Abstract
Description
Technical Field
[0001] This invention relates to the technical field of pesticide spraying, and more particularly to a pesticide spraying device. Background Technology
[0002] Pesticides are chemical compounds that help plants prevent and control harmful organisms. They are widely used in agricultural, forestry, and animal husbandry production, agricultural environments, and sanitation pest control. Pesticides are usually dispersed into the environment by liquid spraying, such as by pesticide trucks or drones. During pesticide spraying, different plants require different amounts of pesticide, so the flow rate needs to be controlled by the nozzle. The flow rate is controlled by rotating a knob at the front of the nozzle. However, in automated spraying systems, such as drones or automatic spraying equipment in greenhouses, it is impossible for personnel to adjust a single nozzle, requiring equipment shutdown or a large number of personnel. Therefore, a pesticide spraying device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] Based on the technical problems existing in the background art, the present invention proposes a pesticide spraying device, including a bracket with an inner cavity, a valve connected to a liquid storage tank is installed on the outside of the bracket, a rocker plate is installed in the inner cavity of the bracket, a rod assembly inserted into the valve is installed at one end of the rocker plate, and an adjusting component for controlling the rotation of the rocker plate is also installed in the inner cavity of the bracket. When the rocker plate rotates, the rod assembly can control the liquid flow rate in the valve.
[0005] Preferably, the valve is provided with a liquid storage tank and an inlet channel and an outlet channel communicating with the liquid storage tank. The valve is provided with a first interface communicating with the inlet end of the inlet channel and a second interface communicating with the outlet end of the outlet channel. The liquid storage tank is connected to the first interface.
[0006] Preferably, the rocker is located in the inner cavity, with one end rotatably connected to the bracket, and the rod assembly rotatably connected to the other end of the rocker.
[0007] Preferably, the rod assembly includes a valve stem, a connecting rod, and a connecting block. The connecting block is connected to the end of the rocker plate. The valve stem extends from the inner cavity to the outside of the bracket and into the valve, and is located in the liquid storage tank. One end of the connecting rod is rotatably connected to the end of the valve stem away from the valve, and the other end of the connecting rod is rotatably connected to the connecting block.
[0008] Preferably, the side of the rocker plate facing the valve is provided with an elastic element, which is located in the inner cavity, and the two ends of the elastic element respectively abut against the connecting block and the inner wall of the bracket.
[0009] Preferably, the elastic element is sleeved on the outer periphery of the connecting rod.

[0018] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0019] Example
[0020] Please refer to Figures 1-2 This invention proposes a pesticide spraying device, including a support 1 with an inner cavity 11. A rocker plate 4 is rotatably installed in the support 1. One end of the rocker plate 4 is a free end, which can move closer to or away from one side of the support 1. A rod assembly 5 is rotatably installed on the free end. The rod assembly 5 includes a valve stem 51, a connecting rod 52, and a connecting block 53. The free end of the rocker plate 4 is provided with an installation groove. The connecting block 53 is installed in the corresponding installation groove and rotatably connected to the rocker plate 4. The rotation axis of the connecting block relative to the rocker plate 4 is parallel to the rotation axis of the rocker plate 4 relative to the support 1. One end of the connecting rod 52 is fixedly connected to the connecting block 53, and the other end is rotatably connected to one end of the valve stem 51. The valve stem 51 extends from the inner cavity 11 to the outside of the support 1.
[0021] Further, refer to Figure 1 , Figure 2 An adjustment component 6 is also installed in the inner cavity 11. The adjustment component 6 can adjust the rotation amplitude of the seesaw 4. The adjustment component 6 includes a drive component 61, a lead screw 62 and a slider 63. The two ends of the lead screw 62 are rotatably connected to the bracket 1. The drive component 61 is located outside the bracket 1 and connected to one end of the lead screw 62. The slider 63 is slidably installed on the lead screw 62 and located in the inner cavity 11. A roller 631 is rotatably installed on the side of the slider 63 facing the seesaw 4. The roller 631 is in contact with the surface of the seesaw 4. When the slider 63 slides along the axial direction of the lead screw 62, it can squeeze the free end of the seesaw 4 close to the side of the bracket 1 and make the valve stem 51 slide out of the bracket 1. The connecting rod 52 is fitted with an elastic element 7. The elastic element 7 is a spring. The two ends of the spring abut against the connecting block 53 and the inner wall of the inner cavity 11, respectively. The elastic element 7 can push the free end of the seesaw 4 closer to the lead screw 62.
[0022] Further, refer to Figure 1 , Figure 2A valve 2 is installed outside the bracket 1. The valve 2 is equipped with a liquid storage tank 21, a liquid inlet channel 22, and a liquid outlet channel 23. The outlet of the liquid inlet channel 22 is connected to the middle of the liquid storage tank 21. The valve 2 is provided with a first interface 24 that is connected to the inlet of the liquid inlet channel 22. The inlet of the liquid outlet channel 23 is connected to the end of the liquid storage tank 21. The valve 2 is also provided with a second interface 25 that is connected to the liquid outlet channel 23. The first interface 24 is connected to the liquid storage tank 3. The second interface 25 is connected to the nozzle. The valve stem 51 passes through the valve 2 and faces the inlet of the liquid outlet channel 23. When the valve stem 51 slides, it can move closer to or further away from the inlet of the liquid outlet channel 23, thereby changing the size of the inlet at the inlet of the liquid outlet channel 23 and thus changing the liquid flow rate.
[0023] In specific implementation, refer to Figure 1 , Figure 2 The bracket 1 has a limiting member 8 installed in its inner cavity 11, and the slider 63 moves between the two limiting members 8.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
