Thus, the main unit Um and the cleaning unit U1 are connected by the connection line Us having the waste liquid tube 16 including the cleaning liquid tubes 13a and 13b and the connection cable 81. In this manner, if the cleaning liquid tubes 13a and 13b are inserted into the waste liquid tube 16, even if there are a plurality of cleaning liquid tubes 13a and 13b, the apparent appearance of the single waste liquid tube 16 is sufficient. There is an advantage that appearance can be improved by avoiding complexity.

  On the other hand, in the main body unit Um, the two connection lines of the intake fan 17 and the two connection lines of the electromagnetic valve 23 are connected to the inner connection terminal of the second connector 67. The upper end of one joint pipe 69a is connected to the outlet 23o of the electromagnetic valve 23 via the liquid distribution tube 82a, and the inlet 23i of the electromagnetic valve 23 is connected to the three-way joint 92 (via the liquid distribution tube. Connect to the first connection end in FIG. Further, the upper end port of the other joint pipe 69b is connected to the second connection end of the three-way joint 92 via the liquid distribution tube 82b, and the third connection end of the three-way joint 92 is connected to the cleaning liquid tube via the liquid distribution tube. Connect to the inner end of the connection port 66. If a Y-shaped tube is used as the liquid distribution tube, the three-way joint 92 is not necessary.

  On the other hand, one end of the suction tube 95 is connected to the suction port of the liquid feed pump 14 disposed in the control unit Uc, and the other end side of the suction tube 95 is passed through the tube insertion hole 71 s provided in the lid portion 71. Insert into the reservoir 12. One end of the cleaning liquid tube 96 is connected to the discharge port of the liquid feed pump 14, and the other end of the cleaning liquid tube 96 is connected to the outer end port of the cleaning liquid tube connection port 66. Further, the connector 77 disposed in the control unit Uc is connected to the second connector 67 disposed in the main unit Um via the connection cable 98. Therefore, the control unit Uc and the main unit Um are connected to the electrical system via the connection cable 98 and to the cleaning liquid supply system via the cleaning liquid tube 96.

  Next, the usage method and operation | movement of the nipple washing apparatus 1 which concern on this embodiment are demonstrated based on FIGS. 10-13, referring FIGS.

  When using the nipple cleaning apparatus 1, a predetermined amount of the cleaning liquid L is stored in the cleaning liquid storage unit 12 and the battery 26 is charged. Thereafter, the operator pushes the nipple washing apparatus 1 by hand and moves the nipple washing apparatus 1 to an arbitrary use place in a suitable tethered barn using the nipple washing apparatus 1. Then, the operator holds the cleaning unit U1 by hand and inserts the nipple Cm of the cow C into the insertion opening 2i of the brush cup portion 2 as shown in FIG. Since the second cleaning brush portion 3b in the cleaning unit U1 is biased upward by the springs 38 ..., when the nipple Cm is not inserted, it is at the highest position shown in FIG. 9, but the nipple Cm is inserted. Then, as shown in FIG.

  On the other hand, the cleaning includes preliminary cleaning and main cleaning. FIG. 10 shows a timing chart of a sequence control pattern used when performing preliminary cleaning and main cleaning. First, pre-cleaning is performed. The preliminary cleaning is performed for the purpose of facilitating removal of dirt in the main cleaning by wetting each teat Cm... With the cleaning liquid L before the main cleaning.

  First, the operator pushes the operation switch 49 while holding the cleaning unit U1 by hand to turn it on. In this case, it is turned on only while the operation switch 49 is being pressed, and the liquid feed pump 14, the electromagnetic valve 23, the brush motor 37 and the intake fan 17 are turned on in response to the operation switch 49 being turned on. When the liquid feed pump 14 and the electromagnetic valve 23 are turned on, the cleaning liquid L in the cleaning liquid storage section 12 is supplied to the upper injection section 5a and the lower injection section 5b via the two cleaning liquid supply systems 15a and 15b, that is, the cleaning liquid tubes 13a and 13b. Are supplied respectively. Then, as shown in FIG. 11, the cleaning liquid L is injected above the cleaning member 22 from the upper injection holes 33 a... And is injected below the cleaning member 22 from the lower injection holes 33 b. In addition, power is supplied to the brush motor 37 via the battery 26, the controller 74, the connection cable 98, and the connection cable 81, and the brush motor 37 alternately repeats forward rotation and reverse rotation (in the direction of arrow Fpn in FIG. 11). In FIG. 10, Ts indicates the normal rotation (or reverse rotation) time, and Ti indicates the slight stop time of the brush motor 37 between the normal rotation and the reverse rotation. The forward / reverse times can be set to about 0.4 to 0.8 [seconds]. By the rotation of the brush motor 37, the first cleaning brush portion 3a, the second cleaning brush portion 3b, and the cleaning member 22 rotate together, and preliminary cleaning of the teat Cm is performed. Further, since the inside of the waste liquid storage section 25 and the waste liquid tube 16 is sucked when the intake fan 17 is turned on, the used cleaning liquid L inside the brush cup section 2, that is, the waste liquid Lr, passes through the waste liquid tube 16. It is collected and temporarily stored in the waste liquid storage unit 25 in the unit Um. At this time, since the inside of the waste liquid storage unit 25 is sucked, the liquid discharge unit 24 is closed by the check valve 24v.

  Then, the operator releases (OFF) pressing of the operation switch 49 at an appropriate time. In FIG. 10, Ta indicates the ON time of the operation switch 49. The preliminary cleaning is intended to wet the nipple Cm with the cleaning liquid L, and therefore, a short time of about several seconds is sufficient as the time Ta. For the time Ta, the maximum time Tam is set, and when this maximum time Tam is exceeded, a control pattern in the main cleaning described later is obtained. When the operation switch 49 is turned off, the liquid feed pump 14, the electromagnetic valve 23, and the brush motor 37 are also turned off. However, even if the operation switch 49 is turned off, the intake fan 17 is turned off after a time Tb, for example, about several seconds. Thereby, since the intake air inside the waste liquid storage unit 25 is released, the check valve 24v of the drainage unit 24 is opened, and the waste liquid L in the waste liquid storage unit 25 is discharged from the drainage unit 24 to the outside. In addition, since the nipple washing apparatus 1 is normally stopped in a passage or the like in a cowshed, the waste liquid L may be discharged from the drainage part 24 as it is, or a drainage tube may be provided in the drainage part 24 if necessary. You may connect and lead to the drainage channel etc. which are provided along the channel | path etc. in a cowshed. As described above, if the waste liquid collecting means 18 is provided with the waste liquid storage section 25 that is connected to the waste liquid tube 16 and is negatively pressured by the intake fan 17 and has the drainage section 24 that discharges the collected waste liquid Lr to the outside. There is an advantage that the waste liquid Lr can be reliably recovered and then reliably disposed at a predetermined disposal place. Thus, the preliminary cleaning of one nipple Cm is completed. The same preliminary cleaning is sequentially performed on the other three teats Cm.

  When the preliminary cleaning is completed, the main cleaning is then performed. Although the basic operation in the main cleaning is the same as that in the preliminary cleaning, the operator can arbitrarily change the time for pressing the operation switch 49 (ON time) in consideration of the degree of contamination of the teat Cm. First, the nipple Cm is inserted into the cleaning unit U1. Then, the operation switch 49 is pressed to turn it ON. When the operation switch 49 is turned on, the liquid feed pump 14, the electromagnetic valve 23, the brush motor 37, and the intake fan 17 are turned on. Therefore, as in the case of the preliminary cleaning, the cleaning liquid L in the cleaning liquid storage unit 12 is supplied to the upper injection unit 5a and the lower injection unit 5b via the cleaning liquid tubes 13a and 13b. Then, as shown in FIG. 11, the cleaning liquid L is injected above the cleaning member 22 from the upper injection holes 33 u... And is injected below the cleaning member 22 from the lower injection holes 33 d. Further, the brush motor 37 repeats forward rotation and reverse rotation alternately (in the direction of arrow Fpn in FIG. 11). By the rotation of the brush motor 37, the first cleaning brush portion 3a, the second cleaning brush portion 3b, and the cleaning member 22 are integrally rotated, and main cleaning is performed on the teat Cm.

  In this case, the first cleaning brush portion 3a cleans the peripheral surface portion Cmf of the nipple Cm with the brush-like cleaning brush 3ax. Further, the second cleaning brush portion 3b cleans the boundary surface portion at the tip portion Cms of the nipple Cm with the boundary surface cleaning brush 3bx... And the tip surface portion portion at the tip portion Cms of the nipple Cm with the tip surface cleaning brush 3bc. Wash. At this time, the boundary curved surface cleaning brushes 3bx... Are sheet-like and have an advantage that dust does not easily adhere to them, and the tip surface cleaning brush 3bc uses cylindrical protrusions 43. In particular, there is an advantage that various shapes including a recess at the tip Cms of the nipple Cm can be cleaned. Further, by the rotation of the cleaning member 22, the root portion Cmb in the teat Cm is cleaned by the cleaning unit 22 w (fin-shaped portion 22 wf...), And this cleaning is performed by injection from the upper injection unit 5 a disposed above the cleaning member 22. The cleaning liquid L to be used is used. At this time, since the disc-shaped cleaning member 22 is used, the dust is removed by the cleaning member 22 before being scraped off by the brush of the brush mechanism unit 3 and is quickly flushed by the cleaning liquid L. . That is, the cleaning liquid L used for cleaning the root portion Cmb enters the inside through the gap between the insertion hole 22i of the cleaning member 22 and the nipple Cm by the cleaning water pressure and the suction pressure, travels through the peripheral surface portion Cmf of the nipple Cm, and the tip Cms. Flushed to the side. Further, since the inside of the waste liquid tube 16 is sucked by the intake fan 17, the waste liquid Lr inside the brush cup portion 2 is collected and temporarily stored in the waste liquid storage portion 25 of the main unit Um via the waste liquid tube 16. The

  Then, the operator releases (OFF) pressing of the operation switch 49 at an appropriate time. In FIG. 10, Td indicates the ON time of the operation switch 48. Since the main cleaning is regular cleaning, the time Td is set longer than the time Ta during the preliminary cleaning. In the example, the time Td is about twice the time Ta. Since the time Td exceeds the maximum time Tam, the electromagnetic valve 23 is automatically turned OFF when the maximum time Tam has elapsed, and the injection of the cleaning liquid L from the upper injection unit 5a is stopped. Therefore, after the maximum time Tam has elapsed, the substantial cleaning of the root portion Cmb of the nipple Cm is completed, and the cleaning member 22 starts draining and drying by the rotating fin-like portions 22wf.

  When the operation switch 49 is turned OFF, the rotation of the brush motor 37 rotates only in the forward rotation direction (in the direction of arrow Fp in FIG. 11) as shown in FIG. The liquid feed pump 14 continues to be turned on as it is, and the liquid feed pump 14 and the brush motor 37 are turned off after a preset Te time (for example, about several seconds) elapses. Therefore, after the operation switch 49 is turned OFF, the cleaning unit U1 is detached from the teat Cm within this Te time. In this case, since the cleaning member 22 functions as a blower fan by the rotating fin-like portions 22wf ... within the Te time, the cleaning unit U1 is quickly removed from the teat Cm within the Te time. Smooth draining and drying. In particular, in addition to such a fan function, even when the cleaning liquid L is continuously sprayed from the lower spraying portion 5b during the separation, the portion of the peripheral surface portion Cmf of the nipple Cm is larger than the insertion hole 22i of the cleaning member 22 In addition, liquid drainage is performed by the insertion hole 22i, and a portion where the diameter of the peripheral surface portion Cmf of the nipple Cm is smaller than the insertion hole 22i of the cleaning member 22 is a high-speed approach of air from the gap between the insertion hole 22i and the peripheral surface portion Cmf. Rapid liquid draining and drying can be performed by rotating the brush mechanism unit 3 only in the forward rotation direction. FIG. 12 shows a state at the time of separation. When the Tf time (for example, about several seconds) elapses after the Te time has elapsed, the intake fan 17 is automatically turned off. Thus, the main cleaning of one nipple Cm is completed. The same main cleaning is sequentially performed on the other three teats Cm. Thereby, a series of cleaning operations are completed.

  Therefore, according to the teat washing apparatus 1 according to this embodiment, the washing unit U1 and the main body unit U2 are mounted and the movable carriage unit 11 is provided, and the main body U2 contains the cleaning liquid L. Since the storage section 12 and the cleaning liquid supply means 6 capable of supplying the cleaning liquid L of the cleaning liquid storage section 12 to the cleaning unit U1 are provided, the storage section 12 is used particularly for a large number of cows C ... like a tethered cowshed. Even if it is a case, it can handle easily and can improve the usability of the washing | cleaning apparatus 1 whole, and also convenience and practicality. In addition, it is possible to reduce unnecessary man-hours such as frequent addition work of the cleaning liquid L and improve work efficiency. Further, the cleaning liquid supply means 6 having two cleaning liquid supply systems 15a having a liquid feed pump 14 capable of supplying the cleaning liquid L in the cleaning liquid storage section 12 to the two injection sections 5a in the cleaning unit U1 through the cleaning liquid tubes 13a. Therefore, effective and sufficient cleaning (wiping) of the nipple Cm can be performed. Therefore, adhesion of dirt to the teat cup liner is avoided, which can contribute to ensuring hygienic production of milk, preventing milk quality deterioration and mastitis, and eliminating residual dirt. Additional cleaning by work can be made unnecessary or reduced.

  On the other hand, FIG. 14 shows a teat washing apparatus 1 according to a modified embodiment of the present invention. The teat cleaning apparatus 1 shown in FIG. 14 is configured such that the cart unit 11, the cleaning liquid storage unit 12, and the control unit Uc are integrated in a shape (design) with respect to the teat cleaning apparatus 1 shown in FIGS. In particular, the cleaning liquid storage unit 12 is fixed to the carriage unit 11. Therefore, there is an advantage that the cleaning liquid storage unit 12 can be stably mounted on the carriage unit 11. In addition, the movable support mechanism 21 has a U-shaped first arm portion 101 whose rear end is rotatably supported with respect to the carriage unit 11, and the rear end can be rotated at the front end of the first arm portion 101. A U-shaped second arm portion 102 coupled to the second arm portion 102 and a hook portion 103 fixed to the tip of the second arm portion 102. Thereby, the handle part 63 provided in the main body unit Um can be hung on the hook part 103 and hung. Reference numeral 104 denotes a cap of the purified liquid storage unit 12. In addition, in FIG. 14, the same reference numerals are given to the same portions (same function portions) as those in FIGS. 1 to 9 to clarify the configuration.

  Although various embodiments have been described in detail above, the present invention is not limited to such embodiments, and the detailed configuration, shape, quantity, numerical values, and the like are within the scope not departing from the gist of the present invention. , Can be changed, added and deleted arbitrarily. For example, although the cart part 11 illustrated the type moved manually, the type moved with motive power (an electric motor etc.) is not excluded. In addition, when there is a power outlet at a required position such as a barn, a DC power supply unit having a power plug can be mounted instead of the battery 26. On the other hand, although the illustrated teat washing apparatus 1 has shown the case where the liquid feeding pump 14 and the lower injection | pouring part 5b were directly connected and comprised the washing | cleaning liquid supply system 15b, the liquid feeding pump 14 was shown similarly to the washing | cleaning liquid supply system 15a side. And the lower injection part 5b may be connected via an electromagnetic valve 23s. If the cleaning liquid supply system 15b is configured by directly connecting the liquid feed pump 14 and the lower injection unit 5b, the use of one electromagnetic valve 23s can be omitted. Therefore, there is an advantage that the configuration can be simplified and the number of parts can be reduced, thereby contributing to cost reduction. However, if the liquid feed pump 14 and the lower injection unit 5b are connected via the electromagnetic valve 23s, more flexible and diverse control can be performed on the cleaning liquid supply system 15a and the cleaning liquid supply system 15b. In particular, in this case, separate cleaning liquid storage units 12 and 12 are connected to the cleaning liquid supply system 15a and the cleaning liquid supply system 15b, respectively, and different cleaning liquids L and L, for example, one of the cleaning liquid storage units 12 and 12 are connected. It is also possible to store a normal cleaning solution in the cleaning liquid reservoir 12 and a disinfectant or pure water in the other cleaning liquid reservoir 12. Furthermore, although the case where the electromagnetic valves 23 and 23s function as opening / closing valves is illustrated, they may be functioned as control valves whose opening amounts are variable as necessary. In addition, although the case where the cleaning unit 22w is configured by the fin-shaped portions 22wf... Protruding upward from the upper surface of the cleaning member 22 is shown, the cleaning unit 22w configured in a brush shape is not excluded. Moreover, although the brush mechanism part 3 showed the case where it comprised with the 1st washing | cleaning brush part 3a which wash | cleans the peripheral surface part Cmf of the nipple Cm, and the 2nd washing | cleaning brush part 3b which wash | cleans the front-end | tip part Cms of the nipple Cm, The cleaning brush portion 3a and the second cleaning brush portion 3b may be configured integrally. In addition, the nipple washing | cleaning apparatus in this invention is the concept containing a nipple wiping apparatus.
