The user opens the cover on the top of the medicine storage bin 1, pours the pesticide into the inside of the medicine storage bin 1, and starts the driving device 4 to make the spraying tubes 6 on both sides of the medicine storage bin 1 spray the pesticide onto the seedlings. At the same time, the driving device 4 drives the driving wheel 2 to rotate, and controls the medicine storage bin 1 to move forward through the handrail 3. By pulling the pull rod 9 outward, the clamping plate 10 is driven to move outward, the limit on the connecting square tube 11 is released, and the connecting square tube 11 is moved upward, so that the spraying tube 6 can spray the pesticide to a higher position, which is convenient for spraying seedlings of different ages.

When the user needs to adjust the height of the spray pipe 6, the first threaded rod 12 is rotated to move the first threaded rod 12 outward, and the limit on the clamping plate 10 is released. The pull rod 9 is pulled to drive the clamping plate 10 to move outward, and the limit on the connecting square tube 11 is released. The connecting square tube 11 is moved up and down to adjust the height of the spray pipe 6 to a suitable position, and the first threaded rod 12 is rotated in the opposite direction to push the clamping plate 10 inward, so as to squeeze the connecting square tube 11 and fix the position of the connecting square tube 11.

[0024] Reference Figure 5As shown, in the present embodiment: two thrust springs 13 are fixedly connected to one side of the concave block 7, and the top end of the thrust spring 13 is fixedly connected to the inner side of the pull rod 9. The user rotates the first threaded rod 12 to move the first threaded rod 12 outward, thereby releasing the limit on the clamping plate 10, and the clamping plate 10 is driven to move outward under the thrust of the thrust spring 13, thereby releasing the limit on the connecting square tube 11, so that the connecting square tube 11 can be moved up and down to adjust the height.

The user rotates the first threaded rod 12 to move the first threaded rod 12 outward, releases the limit on the connecting square tube 11, and allows the connecting square tube 11 to move up and down. In the process of moving the connecting square tube 11, the limiting block 15 on one side of the connecting square tube 11 moves inside the slide groove 14 to limit the movement of the connecting square tube 11 and prevent the connecting square tube 11 from escaping from the inside of the concave block 7.

[0026] Reference Figure 2 As shown, in this embodiment: the top of the connecting square tube 11 is fixedly connected with a spraying pipe 6, and the surface of the spraying pipe 6 is slidably connected to the inside of the connecting hose 16. After the user pours the pesticide into the inside of the medicine storage bin 1, the spraying pipe 6 is inserted into the inside of the connecting hose 16, and the switch of the driving device 4 is turned on to spray the pesticide through the spraying pipe 6. After the spraying is completed, the spraying pipe 6 is moved upward and taken out from the inside of the connecting hose 16 to prevent the spraying pipe 6 from being too high and encountering obstacles when the equipment moves.

[0027] Reference Figure 2 As shown, in this embodiment: a clamping ring 17 is slidably connected to the surface of the connecting hose 16, and two connecting blocks 18 are fixedly connected to the surface of the clamping ring 17. The internal threads of the connecting blocks 18 are connected to a second threaded rod 19. The user inserts the spraying pipe 6 into the connecting hose 16, rotates the second threaded rod 19, tightens the clamping ring 17, fixes the spraying pipe 6, and prevents the gap between the connecting hose 16 and the spraying pipe 6 from causing the pesticide to flow out and cause waste.

[0028] Reference Figure 2 As shown, in this embodiment: the material of the connecting hose 16 is polypropylene, which is a lightweight, durable, waterproof and corrosion-resistant plastic material. Therefore, the connecting hose 16 is made of polypropylene, which not only has high strength and durability, but can withstand various weather conditions and environmental factors. In addition, the polypropylene material also has good chemical stability, can resist the erosion of pesticides and other chemicals, and ensure the long-term stable operation of the equipment.

[0029] The utility model works as follows: the user opens the lid on the top of the medicine storage bin 1, pours the pesticide into the medicine storage bin 1, starts the driving device 4 to make the spraying pipes 6 on both sides of the medicine storage bin 1 spray the pesticide onto the seedlings, and at the same time the driving device 4 drives the driving wheel 2 to rotate, controls the medicine storage bin 1 to move forward through the handrail 3, drives the clamping plate 10 to move outward by pulling the pull rod 9 outward, releases the limit on the connecting square tube 11, moves the connecting square tube 11 upward, so that the spraying pipe 6 can spray the pesticide to a higher position, rotates the first threaded rod 12 to make the first threaded rod 12 move outward, releases the limit on the clamping plate 10 Limit, pull the pull rod 9 to drive the clamping plate 10 to move outward, release the limit on the connecting square tube 11, move the connecting square tube 11 up and down to adjust the height of the spray tube 6 to a suitable position, reversely rotate the first threaded rod 12 to push the clamping plate 10 to move inward, squeeze the connecting square tube 11, fix the position of the connecting square tube 11, rotate the first threaded rod 12 to move the first threaded rod 12 outward, release the limit on the clamping plate 10, drive the clamping plate 10 to move outward under the thrust of the thrust spring 13, release the limit on the connecting square tube 11, so that the connecting square tube 11 can move up and down to adjust The first threaded rod 12 is rotated to move the first threaded rod 12 outward, and the limit on the connecting square tube 11 is released, so that the connecting square tube 11 can move up and down. In the process of moving the connecting square tube 11, the limit block 15 on one side of the connecting square tube 11 moves inside the slide groove 14 to limit the movement of the connecting square tube 11 and prevent the connecting square tube 11 from escaping from the concave block 7. After the user pours the pesticide into the medicine storage bin 1, the spraying tube 6 is inserted into the connecting hose 16, and the switch of the driving device 4 is turned on to spray the pesticide through the spraying tube 6. After the spraying is completed, the driving device 4 is moved upward. The user moves the spray pipe 6 and takes it out from the inside of the connecting hose 16. The user inserts the spray pipe 6 into the inside of the connecting hose 16 and rotates the second threaded rod 19 to tighten the clamping ring 17 to fix the spray pipe 6. At the same time, it prevents the gap between the connecting hose 16 and the spray pipe 6 from causing the pesticide to flow out. The connecting hose 16 is made of polypropylene, which not only has high strength and durability, but can withstand various weather conditions and environmental factors. In addition, the polypropylene material also has good chemical stability, can resist the erosion of pesticides and other chemicals, and ensure the long-term stable operation of the equipment.
