Description

Technical Field

[0001] The utility model relates to the technical field of crop prevention and treatment, in particular to a medicine sprayer. Background Art

[0002] Plant cultivation industry. The agricultural production sector that cultivates various crops and obtains plant products. Planting industry is one of the main components of agriculture. It is a social production sector that uses the life functions of plants to obtain food, non-staple food, feed and industrial raw materials through artificial cultivation. The spraying of liquid medicine is indispensable in the process of planting and cultivation.

[0003] The patent with publication number CN219961760U discloses a drug sprayer for preventing and controlling leek maggots, which includes a bottom plate, a slide rod symmetrically arranged at the lower end of the bottom plate, two support legs slidingly arranged in the slide rod, one end of each support leg is provided with a universal wheel, a handle is arranged at the upper end of the bottom plate, and a drug storage box is arranged at the upper end of the bottom plate. The device can spray the drug evenly through a spraying mechanism, and can also adjust the spraying height. The sliding distance adjustment mechanism can adjust the distance between the two support legs. However, the device has the problem of using an adjustment block and a bidirectional screw according to the spacing of leek planting. The structure cooperates with the supporting legs and the slide rod to adjust the distance between the supporting legs, and then uses the spray pipe and the rotating spray head to spray the medicine, but the distance between the two spray pipes is fixed. Even if a rotatable spray head is used to spray the medicine, it is difficult to spray the medicine in the middle position during the rotating spraying process, and the sprayer can only move in a straight line at the same position, so it is difficult to ensure that the planting area can be completely sprayed with the medicine through the two fixed position spray heads. For this reason, a medicine sprayer is proposed to solve the problem that it is difficult for the existing sprayer to conveniently adjust the spraying range according to the spraying area.

[0023] Example: See Figure 1-5A medicine sprayer comprises a bottom plate 1, a push handle 2 is fixedly connected to the top of the bottom plate 1, an adjustable leg 3 is arranged at the bottom of the bottom plate 1, a universal wheel 4 is fixedly connected to the bottom of the adjustable leg 3, an adjustment mechanism 5 is arranged at the bottom of the bottom plate 1, a water pump 6 and a liquid medicine tank 13 are arranged at the top of the bottom plate 1, a liquid inlet is provided at the top of the liquid medicine tank 13, a connecting pipe 7 is provided on one side of the water pump 6, a spray pipe 8 is fixedly connected to the bottom of the bottom plate 1, a second spray pipe 9 is provided in the inner cavity of the spray pipe 8, a plurality of spray heads 10 are mutually provided at the bottom of the spray pipe 8, a groove 11 and a second groove 14 are respectively provided at the bottom of the inner cavity of the spray pipe 8, and a connecting plate 12 is fixedly connected to one side of the adjustable leg 3 on the same side.

[0024] Furthermore, the water pump 6 is interconnected with the liquid medicine tank 13, and the connecting pipe 7 is interconnected with the water pump 6 and the spray pipe 8. The width between the adjustable legs 3 is adjusted. During the process, the connecting plate 12 is cooperated, and the second spray pipe 9 is moved out of the spray pipe 8 until the width of the two pipes is equal to the width of the planting area. When the water pump 6 is turned on, the liquid medicine can be pumped from the connecting pipe 7 into the spray pipe 8 and the second spray pipe 9, and the spray head 10 sprays the liquid medicine on the crops evenly.

[0025] Furthermore, the spray head 10 on the spray pipe 8 is communicated with the groove 11, the spray head 10 on the second spray pipe 9 is located in the inner cavity of the second groove 14, and the bottom and the outer circle of the spray head 10 are both in contact with the inner cavity wall of the second groove 14. When the medicine is injected into the spray pipe 8, the medicine will enter the second spray pipe 9 and the groove 11. When the second spray pipe 9 is not moved out of the spray pipe 8, the spray head 10 on the second spray pipe 9 will block the second groove 14 to prevent the medicine from flowing out of the second groove 14 and causing waste. At the same time, the medicine entering the groove 11 will be sprayed out from the spray head 10 on the spray pipe 8; when the second spray pipe 9 is moved out of the spray pipe 8, the medicine will be sprayed out from the spray head 10 on the second spray pipe 9 that is moved out of the spray pipe 8, and from the spray head 10 on the spray pipe 8.

[0026] Furthermore, the adjustment mechanism 5 includes an adjustment seat 508 fixed at both ends of the bottom of the base plate 1 , an adjustment slot 501 is provided at the bottom of the adjustment seat 508 , and two adjustment plates 502 are provided in the inner cavity of the adjustment slot 501 , and the adjustment plates 502 are fixedly connected to the adjustable legs 3 .
