The No. 3 elastic telescopic rod will extend after rotation, and the No. 3 elastic telescopic rod will push the auxiliary wheel to move, so that the auxiliary wheel contacts the ground, increasing the supporting force of the support frame, so that the machine can avoid tipping over due to excessive tilting to one side, causing damage to the machine, and the tipping of the machine may cause a large amount of pesticide to flow out of the storage barrel, and the outflow of pesticide will aggravate the damage of the pesticide to the plants, affecting the growth, development and yield of the crops.

[0018] In the present invention, the rotation of the telescopic push plate will push the push block to move, and the movement of the push block will push the inner plate to slide in the direction away from the outer plate, so that the inner plate will push the buffer plate to move downward. The downward movement of the buffer plate can provide a certain buffer when the left large wheel falls from a high place, thereby avoiding damage to the outer shell, components or internal systems of one side of the machine due to falling from a high place. Once the equipment for spraying pesticides is damaged, it may cause pesticide leakage, causing environmental pollution or harm to people. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In some examples, the protection device also includes two No. 1 hydraulic devices 31, two No. 2 hydraulic devices 392, a pressure plate 393, a fixing sleeve 394, a No. 3 elastic telescopic rod 395 and an auxiliary wheel 396. The No. 1 hydraulic device 31 is fixedly installed on the side of the No. 1 elastic telescopic rod 8 close to the telescopic connecting rod 32, the No. 2 hydraulic device 392 is fixedly installed on the side of the inner rod 12 close to the outer plate 38, the pressure plate 393 is fixedly installed on the movable end of the No. 2 hydraulic device 392, and the No. 3 elastic telescopic rod 395 is rotatably installed on the side of the support frame 1 close to the large wheel 6. The fixing sleeve 394 is fixedly installed on one side of the third elastic telescopic rod 395 close to the pressure plate 393. A square key is fixedly installed at the bottom of the pressure plate 393. The square key contacts the inner wall of the fixing sleeve 394. The auxiliary wheel 396 is rotatably installed at the bottom of the third elastic telescopic rod 395. The buffer plate 391 moves downward to provide a certain buffer when the left large wheel 6 falls from a high place, so as to avoid damage to the outer shell, components or internal systems of one side of the machine caused by falling from a high place. Once the equipment for spraying pesticides is damaged, it may cause pesticide leakage, causing environmental pollution or harm to people.

[0036] A No. 2 torsion spring is provided between the rotating plate 35 and the support frame 1. The No. 2 torsion spring is provided to drive the rotating plate 35 to return to its original position. The telescopic push plate 36 contacts the top of the push block 37. A No. 3 spring is provided between the outer plate 38 and the inner plate 39. The No. 3 spring is provided to push the inner plate 39 to move away from the outer plate 38. A No. 4 spring is provided between the buffer plate 391 and the inner plate 39. The No. 4 spring is provided to enable the buffer plate 391 to play a buffering role when falling from a high place. A No. 3 torsion spring is provided between the No. 3 elastic telescopic rod 395 and the support frame 1. The No. 3 torsion spring is provided to be driven by the No. 3 torsion spring to rotate when the limit of the No. 3 elastic telescopic rod 395 is released. The No. 1 hydraulic device 31 on the left is connected with the No. 2 hydraulic device 392 on the right through a No. 1 hose, and the No. 1 hydraulic device 31 on the right is connected with the No. 2 hydraulic device 392 on the left through a No. 2 hose.

[0037] For example, Figure 1 to Figure 9 As shown, when the No. 1 rack 192 pushes the gear shaft 193 to rotate, the thin rope 20 will be pulled to be tightened. When the thin rope 20 is pulled by the gear shaft 193, the thin rope 20 will pull the control end of the No. 1 valve 21 to rotate, so that the flow rate of the pesticide in the No. 1 valve 21 increases. The rotation of the No. 1 valve 21 will drive the linkage rod 22 to move, and the movement of the linkage rod 22 will drive the control end of the No. 2 valve 23 to rotate. The rotation of the control end of the No. 2 valve 23 will cancel the obstruction of the movable nozzle 24, so that the pesticide can flow out through the movable nozzle 24 to increase the spraying flow of the pesticide, and avoid that the amount of pesticide discharged does not increase when the spraying range of the pesticide increases, which may result in insufficient pesticide concentration, unable to effectively control pests or pathogens, and affect the prevention and control effect. The rotation of the control end of the No. 2 valve 23 will drive the connecting rod 26 to move, and the movement of the connecting rod 26 will drive the rotating rod 27 to rotate, then the rotating rod 27 will rotate. The movable rod 27 will be in the same straight line as the connecting rod 26, and the rotating rod 27 will push the movable nozzle 24 to rotate slightly. The rotation of the movable nozzle 24 can prevent the pesticide spraying range of the movable nozzle 24 from overlapping with the spray head 9. The overlap of the spraying position will cause the same area to be sprayed repeatedly, which will cause a waste of pesticides. Excessive spraying not only increases the cost of pesticide use, but may also cause unnecessary environmental pollution. The rotation of the movable nozzle 24 will drive the baffle 25 to move, and the movement of the baffle 25 will drive the L-shaped rod 29 to move. The movement of the L-shaped rod 29 will contact the inclined surface of the fixed block 28, and the fixed block 28 will press the L-shaped rod 29 to move. The movement of the L-shaped rod 29 will drive the baffle 25 to rotate. The rotation of the baffle 25 will remove the obstruction to the spraying range of the movable nozzle 24, so that the pesticide can be sprayed to a larger range, further increasing the spraying range of the pesticide and improving work efficiency.

[0038] When the left wheel 7 hits a larger stone or earth slope during the forward movement of the machine, the wheel 7 will move toward the No. 1 hydraulic device 31. When the wheel 7 moves toward the No. 1 hydraulic device 31, it will push the telescopic connecting rod 32 to move. The movement of the telescopic connecting rod 32 will push the movable end of the No. 1 hydraulic device 31, so that the movable end of the No. 1 hydraulic device 31 moves toward the inside of the No. 1 hydraulic device 31. Then, the movable end of the No. 1 hydraulic device 31 will press the liquid inside the No. 1 hydraulic device 31 through the hose into the inside of the No. 2 hydraulic device 392 on the right. The increase of liquid in the inner wall of the hydraulic device 392 will push the movable end of the No. 2 hydraulic device 392 to move away from the No. 2 hydraulic device 392, and the movement of the movable end of the No. 2 hydraulic device 392 will push the pressure plate 393 to move upward, and the upward movement of the pressure plate 393 will drive the square key to move, and the movement of the square key will lose contact with the inner wall of the fixed sleeve 394, and the limit of the No. 3 elastic telescopic rod 395 will be released, and the No. 3 elastic telescopic rod 395 will be driven by the No. 3 torsion spring to rotate in the direction away from the support frame 1. After the rotation, the No. 3 elastic telescopic rod 395 When the telescopic link 32 moves, the push plate 33 is driven to move, and the push plate 33 moves to move the sliding plate 34, and the sliding plate 34 moves to drive the rotating plate 33 to move. The plate 35 rotates, and the rotation of the rotating plate 35 will drive the telescopic push plate 36 to move. The rotation of the telescopic push plate 36 will push the push block 37 to move. The movement of the push block 37 will push the inner plate 39 to slide in the direction away from the outer plate 38, and the inner plate 39 will push the buffer plate 391 to move downward. The downward movement of the buffer plate 391 can provide a certain buffer when the left large wheel 6 falls from a high place, avoiding damage to the outer shell, components or internal systems of one side of the machine due to falling from a high place. Once the equipment for spraying pesticides is damaged, it may cause pesticide leakage, causing environmental pollution or harm to people.
