Description

Technical Field

[0001] This utility model relates to the field of pesticide applicator technology, specifically a handheld pesticide applicator. Background Technology

[0002] A pesticide applicator is a machine used to apply chemical pesticides; it is also known as plant protection machinery or agricultural spraying equipment. Its function is to evenly distribute a certain amount of pesticide solution or powder onto fields or crops according to the control requirements, in order to prevent and control the damage of pests to crops. The main role of pesticide applicators in agriculture is to efficiently and precisely apply chemical pesticides to prevent and control the damage of pests to crops, while improving agricultural production efficiency. Pesticide applicators can save a significant amount of manpower and time costs. Compared to manual application, using a pesticide applicator allows for faster completion of large-area pesticide spraying operations. Pesticide applicators avoid the uneven application problems that can occur with manual operation, ensuring that pesticides are evenly covered on crops, thereby improving pesticide utilization and control effectiveness.

[0003] Existing pesticide applicators are often handheld, which spray a fixed amount of pesticide each time. If a large amount of pesticide needs to be sprayed or a small amount of pesticide needs to be sprayed, it may result in insufficient or excessive spraying, which may lead to waste or failure to achieve the expected results.

[0004] To address these issues, we designed a handheld applicator. Utility Model Content

[0005] The purpose of this invention is to provide a handheld applicator to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a handheld pesticide applicator, including a tube wall. A rotating body is rotatably connected to the middle surface of the tube wall. The top and bottom of the rotating body are provided with first mounting grooves. A compression spring is fixedly installed on the inner wall surface of one end of each first mounting groove. A pressing block is fixedly installed on the other end of the compression spring. A pesticide storage ring is fixedly installed on the inner wall of the tube wall. A pesticide dispensing block is inserted into the top of the pesticide storage ring. A base plate is fixedly installed at the bottom of the pesticide dispensing block.

[0007] Furthermore, the top of the dispensing block is symmetrically provided with second mounting grooves, and each second mounting groove has a tension spring fixedly installed on its inner wall, with the other end of the tension spring fixedly connected to both ends of the base plate.

[0008] Furthermore, a gun body is fixedly provided on one side surface of the tube wall, and a grip is fixedly provided on the bottom of the gun body.

[0009] Furthermore, a pressing block is slidably connected to one side of the grip.

[0010] Further, the inner wall surface of the handle is fixedly provided with a pumping device, and the pressing block is fixedly connected with the telescopic end of the pumping device.

[0011] Further, the top of the pumping device is fixedly provided with an air outlet pipe, and the other end of the air outlet pipe is fixedly connected with the inner wall surface of one side of the pipe wall.

[0012] Further, the other side surface of the pipe wall is fixedly provided with a spray head, and the inside of the spray head is provided with a filter screen.

[0013] Compared with the prior art, the beneficial effects of the utility model are that: through rotating the rotating body, when the lower pressing block in the rotating body rotates to the upper side of the medicine discharging block, the lower pressing block pushes the medicine discharging block under the elasticity of the compression spring, so that the medicine discharging block drives the bottom plate to move to the inside of the medicine storage ring, the medicine stored in the medicine storage ring will flow to the inside of the medicine storage ring through the gap between the medicine storage ring and the medicine discharging block, and through rotating the rotating body for many times, different doses of medicine can be stored in the inside of the medicine storage ring, so that the control of the medicine dose can be realized.

[0014] Compared with the prior art, the beneficial effects of the utility model are that: through setting the spray head at one end of the pipe wall and setting the filter screen in the inside of the spray head, when the medicine reaches one end of the spray head, the medicine will be sprayed to the outside through the filter screen and sprayed to crops, and the medicine sprayed from the other end of the filter screen will be concentrated together, so that the filter screen only needs to be aimed at the place needed to be sprayed, and positioning spraying is realized.
