Abstract
The utility model discloses a grass cutter which is provided with a grass cutting blade that can be lifted manually. The grass cutter comprises a grass cutting power system which consists of the grass cutting blade, a grass cutting motor and a cutter shaft; the grass cutter has the structural characteristics that the grass cutter is also provided with a lifting power system which comprises a revolving switch, a knife rest and a base, wherein the revolving switch is rotatablely positioned in the base, the knife rest is connected with the revolving switch by screw thread in a lifting way, the grass cutting motor is installed on the base and is connected with the cutter shaft in a driving way, and the grass cutting blade is fixed on the cutter shaft that is installed in the knife rest. The utility model has the advantages of prolonging the service life of batteries, improving the efficiency on cutting grass and being safe to operate.
Description
Technical field
The utility model relates to a kind of mower, but especially a kind of mower of the blade hand-operated lifting of mowing.
Background technology
The mowing blade of existing mower is fixing mostly, through higher careless of growth to be cut the time, the operating current of mowing motor will rise, long-term work like this can reduce the service life of battery, and the long-term big electric current mowing motor of work is down burnt easily, not only reduce the mowing efficient of mower, also damaged equipment.If adjust the height of mowing blade as required, then need to unclamp earlier the fixed screw of blade, again screw is fixed after adjusting to proper height, more loaded down with trivial details, and blade is sharper, can produce danger.
Summary of the invention
But technical problem to be solved in the utility model provides a kind of mower that prolongs battery service life, improves the mowing blade hand-operated lifting of mowing efficient, handling safety.
The technical scheme in the invention for solving the above technical problem is: this mower comprises the mowing dynamical system of being made up of mowing blade, mowing motor and cutter shaft, its design feature is also to be provided with the lifting dynamical system that comprises rotary switch, knife rest and base, rotary switch rotatably is positioned at base, knife rest liftably is threaded with rotary switch, the mowing motor is installed on the base and with the cutter shaft driving and is connected, the mowing blade is fixed on the cutter shaft, and cutter shaft is installed in the knife rest.
Cutter shaft described in the utility model is installed in the knife rest by rolling bearing.
Mowing motor described in the utility model, knife rest, cutter shaft, rolling bearing and mowing blade are respectively two groups.
The utility model also is equipped with dust cover below base.
Rotary switch described in the utility model is installed in and covers.
The utility model compared with prior art, has following beneficial effect: rotary switch can be installed in the base by 360 degree with rotating freely, knife rest can be threaded in the rotary switch below with rotary switch with moving up and down, cutter shaft is installed in the knife rest by rolling bearing, by being rotated, rotary switch can drive knife rest rising or decline, knife rest drives cutter shaft again and moves up and down, thereby manually control the lifting of mowing blade, avoided using screwdriver or other instruments to adjust the height of mowing blade, reached the purpose of before mowing, arbitrarily adjusting the mowing blade height, make work simpler and easy easily, safety improves greatly, and also prolong to some extent the service life of battery.

Fig. 2 is the vertical view of the utility model embodiment.
Fig. 3 is A-A cutaway view of Fig. 1.
Embodiment
Referring to Fig. 1～Fig. 3, present embodiment is made up of mowing dynamical system and lifting dynamical system.The mowing dynamical system comprises mowing blade 9, mowing motor 3 and cutter shaft 4, and the lifting dynamical system comprises rotary switch 1, knife rest 6, base 7, loam cake 2 and rolling bearing 5, and the lifting dynamical system has two groups.
Rotary switch 1 is installed on the loam cake 2, and can 360 degree be positioned at base 7 with rotating freely, 1 of rotary switch is rotatable, can not move up and down.Knife rest 6 is installed on the base 7 and liftably is threaded with rotary switch 1, knife rest 6 oscilaltion only, can not rotate freely by 360 degree.Because for being threaded, rotary switch 1 is installed on the loam cake 2 between rotary switch 1 and the knife rest 6, knife rest 6 is installed on the base 7, so rotary switch 1 just can drive knife rest 6 by being threaded and rise or descend when 360 degree rotations.Mowing motor 3 is installed on the base 7 and with cutter shaft 4 drivings and is connected.Mowing blade 9 is fixed on the cutter shaft 4, and cutter shaft 4 is installed in the knife rest 6 by rolling bearing 5, when knife rest 6 moves up and down, can drive cutter shaft 4 and also move up and down.Dust cover 8 also is installed below base 7.
During mowing, the driving shaft of mowing motor 3 drives cutter shaft 4 rotations, and cutter shaft 4 drives 9 work of mowing blade, begins to mow.
When needing to regulate the height of mowing blade 9, rotary switch 1 is rotated, rotary switch 1 drives knife rest 6 and rises or descend, knife rest 6 drives cutter shaft 5 by rolling bearing again and rises or descend, owing to be fixed on the cutter shaft 4 during mowing blade 9, so just realized the function that can manual adjustments mowing blade 9 rises or descend.The mowing blade 9 that can raise in the higher place of grass growth to reduce the operating current of mowing motor 3, after having cut one time, is regulated the height of mowing blade 9, the nursing of further mowing again.
