Step one, when the device moves, the output end of the motor 72 drives the first belt pulley 731 to rotate, power is transmitted between the first belt pulley 731 and the second belt pulley 732 through the synchronous belt 733, the driving shaft 74 drives the chain wheel 761 connected with the first belt pulley to rotate, under the meshing action of the chain teeth of the chain wheel 761 and the chain link of the chain 762, the chain 762 drives the chain wheel 761 positioned below to rotate, so that the output end of the motor 72 drives the two rear side wheels 77 to rotate, and the steering gear 5 can adjust the rotating angles of the two front side wheels 6, so as to steer the device, thereby realizing the movement of the device;

step two, in the moving process of the equipment, the wheel 77 positioned at the rear side drives the transmission shaft 74 to rotate through the chain transmission assembly 76, the rotation shaft 84 is driven to rotate through the meshing of the two bevel gears 81 and the meshing between the first gear 82 and the second gear 83, the rotation shaft 84 drives the limiting rod 856 to rotate, the driving rod 865 is pulled through the connecting rod 866 to drive the piston 862 to move back and forth along the inner cavity of the piston cylinder 861, the piston 862 moves towards the front side, the volume of the inner cavity of the piston cylinder 861 is increased, the inner cavity of the second one-way valve 867 is closed, the first one-way valve 863 is opened, so that liquid is extracted from the water tank 3 through the connecting pipe 864, when the piston 862 moves towards the rear side, the volume of the inner cavity of the piston cylinder 861 is reduced, the first one-way valve 863 is closed, the second one-way valve 867 is opened, the liquid is pressed into the liquid distribution cavity 43 of the irrigation mechanism 4 through the three-way pipe 87 and the two hoses 88 and is sprayed out from the spraying port 44 for irrigation, the rotating speed of the rotating disc 851 is positively correlated with the rotating speed of the rear wheel 77, namely the water amount irrigated in unit area is the same no matter the moving speed of the device is;

step three, adjusting the irrigation water amount in unit area, wherein the output end of the motor 854 drives the screw 855 to rotate, and drives the sliding block 853 to move along the sliding groove 852 under the matching action of the threads, so that the rotating radius of the limiting rod 856 rotating around the rotating shaft 84 is adjusted, the stroke distance of the piston 862 is changed, namely the volume change range between the piston 862 and the piston cylinder 861 is changed, and the irrigation water amount in unit area is adjusted;

this device is convenient for remove, need not the manual work and pulls, and labour saving and time saving irrigates the radiating area great, and the sprinkling irrigation is even, and irrigation efficiency is high to be convenient for control unit area's irrigation water yield, the irrigation water yield that can adjust unit area simultaneously.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
