Description

Sprinkler fault monitoring device

Technical field:

The utility model relates to a sprinkler irrigation machine, in particular to a fault monitoring device for a sprinkler irrigation machine.

Background technique:

DYP series electric circular sprinkler is an indispensable large-scale agricultural machinery equipment for water-saving irrigation of crops in arid areas. Its structure and working principle are as follows: the central support shaft is installed at the center of the irrigated land and fixed with foot bolts; one end of the first-span truss is installed on the top of the central support shaft, and the other end is supported by a tower truck; after the second span, each span They are connected by spherical flexible joints, which are suitable for working on undulating ground; motor reducers and wheel reducers are installed on each span of the tower car as the driving force, and the walking speed of the tower car is controlled by the electronic control synchronization system. The trusses of each span are always rotated around the central axis in the same straight line; the water pipe trusses are equipped with inverted branch pipes and sprinklers, so as to realize self-moving continuous spraying operations and irrigate crops in a circular area of land. However, when the motor reducer is running, there will be problems of over-current, over-voltage, under-voltage or wheel slipping and overloading, which will cause the tower truck to stop automatically. In addition, the sprinkler is very large (one sprinkler can irrigate 1225 acres of land) ), when a fault occurs, it is necessary to run around to check the fault location, and the maintenance is very inconvenient.

Invention content:

The utility model mainly solves the problems existing in the above-mentioned prior art, and provides a fault monitoring device for a sprinkler irrigation machine.

The technical solution adopted by the utility model to solve the technical problems is: a sprinkler irrigation machine failure monitoring device, the sprinkler irrigation machine includes a central support shaft, a water pipe truss, and a tower vehicle, the central support shaft is installed in the center of the irrigated land, and the water pipe truss consists of several One end of the first-span truss is installed on the central support shaft, and the other end is supported by a tower truck. One end of the second-span truss is also set on the tower truck to connect with the first-span truss. A motor reducer is installed, and a control tower box is installed on each span of the tower car. A thermal protection relay is installed in the control tower box. The signal is transmitted to the connected main control box, and the main control box is connected with an alarm display device. When the motor reducer is over-voltage, over-current, under-voltage, traveling wheel slipping, or overloading, the motor heats up, and the thermal protection relay will automatically cut off the power supply of the running motor, and transmit the signal of cutting off the power from the module to the main control box. The control box alarm will alarm and display the position of the faulty motor by numbers.

As a preferred solution of the above solution, the alarm display device includes an alarm unit and a display unit, the alarm unit is a light alarm device or a sound alarm device, and the alarm display device receives the signal sent by the thermal protection relay and displays the fault location on the display device . The alarm display unit can automatically display the location of the fault. The maintenance personnel do not have to run around to find the location of the fault, but can carry out targeted repairs at the location of the fault. For high-stalk crops such as sorghum and corn, it is inconvenient to walk between the fields, and the efficiency of fault repair can be increased by more than ten times, and the effect is relatively obvious.

The utility model has the advantages of simple and reasonable structure. Once the motor reducer is running, it will automatically stop when it is over-current, over-voltage or under-voltage, and the tower wheel will automatically stop when it is climbing, overloaded or slipping, and it will give an alarm through the alarm display device. The location of the faulty motor is displayed by numbers, and when a fault occurs during operation, the maintenance personnel can go to the fault location to repair it, which brings great convenience to find the fault location and repair.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a kind of structural framework schematic diagram of the present utility model.

Detailed ways:

The technical solutions of the present utility model will be further described below through the embodiments and in conjunction with the accompanying drawings.
