[0017] 3. When the crawler-type wide-width mower and pesticide sprayer is in use, the liquid medicine is put into the water tank, and the liquid medicine enters the inner cavity through the bend, floats the float ball, and then enters the inner side of another inner cavity through the bend, and then floats the float ball into the bottom of the water tank, so that the piston moves to the top of the liquid medicine under its own buoyancy, and the air at the bottom of the piston enters the inner side of the bend, and then the pressure generated by the weight of the piston is used to push the float ball upward, and then the air at the bottom of the piston in the water tank is discharged to the top of the piston. As the crawler vehicle moves The shaking caused by the movement allows the medicine liquid to enter the inner side of the inner cavity through the bottom end of the bend, and then floats the float upward. The float stretches the spring and seals the top of the inner cavity, effectively preventing the medicine liquid from entering the top of the piston, and the air cannot float the float into the bottom of the piston, effectively preventing the medicine liquid from being agitated in the water tank. It can avoid the generation of a large amount of foam in the medicine liquid and affecting the spraying effect of the medicine liquid, and can also avoid the agitation of the medicine liquid causing the tracked vehicle to overturn when tilting, thereby ensuring the safe movement of the tracked vehicle.

[0030] In this embodiment, a piston 31 is installed on the inner side of the water tank 10. The density of the piston 31 is less than the density of water. A bend 32 is opened on the inner side of the piston 31. The bends 32 are evenly distributed on the piston 31. The top of the piston 31 is connected to the bottom of the piston 31 through the bend 32. An inner cavity 33 is opened on the inner side of the bend 32. A float 34 is placed on the inner side of the inner cavity 33. The float 34 is stuck in the inner cavity 33. The diameter of the float 34 is larger than the inner diameter of the bend 32, and the diameter of the float 34 is smaller than the inner diameter of the inner cavity 33. The bottom of the float 34 is connected to the inner wall of the bend 32 through the spring 35. When spraying, the liquid medicine is put into the water tank 10, and the liquid medicine enters the inner cavity 33 through the bend 32. After the float 34 is floated, it enters the inner side of another inner cavity 33 through the bend 32, and then the float 34 is floated and enters the bottom of the water tank 10, and then The piston 31 moves to the top of the liquid medicine under its own buoyancy, and the air at the bottom of the piston 31 enters the inner side of the bend 32.

[0031] The crawler-type wide-width mowing and pesticide-spraying machine provides power to all electrical equipment through the crawler vehicle. When in use, after the crawler vehicle 1 moves to the position where the grass is required to be mowed, the telescopic rod 7 is controlled to retract, so that the support rod 6 is rotated downward on the crawler vehicle 1 through the rotating shaft, and then the shield 2 is rotated to the front of the crawler vehicle 1, and then the motor 2 8 is turned on according to the required mowing depth. The motor 2 8 drives the screw 9 to rotate on the support rod 6, and the screw 9 drives the shield 2 to move up and down, which can not only adjust the mowing depth, but also ensure the flatness of the grass after mowing. As the crawler vehicle 1 moves, the motor 1 4 drives the rotary cutter 5 to rotate, and cuts off the grass passing through the bar 3. At the same time, the bar 3 is used to push away the stones in the grass, or the crawler vehicle 1 is blocked and cannot move, effectively ensuring the grass is smooth. The safety of the rotary cutter 5 is prevented by the shield 2 to prevent grass fragments from splashing from both sides. The grass fragments are removed from the back of the shield 2 for subsequent collection. When spraying, the liquid medicine is loaded into the water tank 10, and the liquid medicine enters the inner cavity 33 through the bend 32. After the float 34 is floated, it enters the inner side of another inner cavity 33 through the bend 32, and then the float 34 is floated and enters the bottom of the water tank 10, so that the piston 31 moves to the top of the liquid medicine under its own buoyancy, and the air at the bottom of the piston 31 enters the inner side of the bend 32, and then the pressure generated by the gravity of the piston 31 is used to make the air push the float 34 upward, thereby discharging the air at the bottom of the piston 31 in the water tank 10 to the top of the piston 31. The shaking caused by the movement of the crawler vehicle 1 causes the liquid medicine to pass through the bend The bottom end of the port 32 enters the inner side of the inner cavity 33, thereby floating the float 34 upward, and the float 34 stretches the spring 35 and seals the top of the inner cavity 33, effectively preventing the liquid from entering the top of the piston 31, and the air cannot float the float 34 to the bottom of the piston 31, effectively preventing the liquid from being agitated in the water tank 10, which can not only prevent a large amount of foam from being generated in the liquid and affecting the spraying effect of the liquid, but also prevent the agitation of the liquid from causing the crawler 1 to roll over when tilted, ensuring the movement safety of the crawler 1. When spraying, the motor 3 24 drives the gear 25 to rotate, and the gear 25 engages with the gear ring 26, so that the gear 25 pushes the support plate 23, and the support plate 23 drives the snap ring 22 between the ball sleeve 19 and the support block 2 0 is rotated, so that the support plate 23 pushes the screw rod 30 through the rotating plate 28, and the screw rod 30 pushes the counterweight 14 through the rotating block 27. The counterweight 14 rotates horizontally on the inner side of the ball sleeve 19 through the ball joint 13, thereby driving the nozzle 15 to rotate in order to adjust the direction of spraying. Then the motor 29 is turned on. The motor 29 moves the screw rod 30 on the inner side of the rotating plate 28, so that the screw rod 30 drives the counterweight 14 through the rotating block 27 to rotate up and down on the inner side of the ball sleeve 19 through the ball joint 13, thereby rotating the nozzle 15 up and down to adjust the angle of spraying. The solenoid valve 18 on the main nozzle 16 and the auxiliary nozzle 17 is opened as needed. The main nozzle 16 and the auxiliary nozzle 17 can be opened at the same time to increase the spraying range.It is also possible to open only the main nozzle 16 to increase the spraying distance, and to flexibly adjust the spraying direction, angle and spraying range.
