Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying device technology, and in particular to a pesticide spraying device. Background Technology

[0002] In agricultural production, in order to reduce the occurrence of pests and diseases, pesticide spraying devices are generally used to spray crops to reduce the occurrence of pests and diseases, effectively protect crop resources, and improve crop yields. Pesticide spraying devices have evolved from manual operation to automatic operation, further improving the efficiency of pesticide spraying.

[0003] A search revealed a Chinese patent with patent number CN222442865U, titled "A Pesticide Spraying Device with Liquid-Pesticide Separation." The patent describes a device comprising: a water storage component, a pesticide storage component, a mixing component, and a spraying component; the water storage component includes a water tank and a dispensing pump, with the pump's suction end connected to the bottom of the water tank; the pesticide storage component includes a pesticide tank and a dispensing pump, with the pump's suction end connected to the bottom of the tank; the mixing component includes a mixing housing, within which a stirring mechanism is rotatably mounted. The mixing housing is equipped with an inlet pipe and an outlet pipe. The outlet end of the mixing water pump and the outlet end of the mixing pesticide pump are both connected to the inlet pipe through pipelines. The spraying assembly includes a spray pipe with a nozzle at one end and the other end connected to the outlet pipe through a hose. This allows for the immediate preparation and use of pesticide solutions, preventing waste caused by preparing too much pesticide solution at once. It also allows for timely adjustment of the pesticide concentration during spraying to target specific areas, and facilitates cleaning after spraying.

[0004] However, in actual use, because there is only one nozzle, the coverage of the pesticide spray is insufficient, reducing the spraying range. Therefore, it is necessary to manually shake the nozzle to make it fan-shaped and reciprocate to spray the pesticide in order to increase the spraying range, which further reduces the efficiency of pesticide spraying.

[0005] Therefore, how to provide a pesticide spraying device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a pesticide spraying device. This invention solves the problem in the prior art where there is only one nozzle, resulting in insufficient pesticide spray coverage. This necessitates manually shaking the nozzle to make it fan-shaped and reciprocate to increase the pesticide spraying range, which reduces the efficiency of pesticide spraying.

[0007] A pesticide spraying device according to an embodiment of the present invention includes a pesticide tank body and a nozzle. A handle is fixedly connected to the side of the pesticide tank body through a flexible tube. A main spraying pipe is provided at the other end of the handle. A branch pipe is fixedly connected to the surface of the main spraying pipe through a flexible connecting tube. A fixing frame is fixedly sleeved on the surface of the main pipe corresponding to the position of the branch pipe. The branch pipe is set on the fixing frame. A docking component is provided at the end of the branch pipe and the main spraying pipe away from the handle. The nozzle is set on the docking component.

[0008] The surface of the branch pipe is provided with a first rotating shaft, which is rotatably connected to the lower surface of the fixing frame near the end face.

[0009] The number of branch pipes is two sets, and the two sets of branch pipes are symmetrically arranged on both sides of the main spraying pipe.

[0010] The main spray pipe is fitted with an angle adjustment element that adjusts the angle between the branch pipe and the main spray pipe.

[0011] The angle adjustment component includes a movable frame, a movable block, a damping ring, a movable ring, and a second rotating shaft. The damping ring is fixedly connected to the inner wall of the movable block. The movable block is movably sleeved on the surface of the main spray pipe through the damping ring. The movable frame is fixedly connected to the surface of the movable block. The movable ring is movably sleeved on the surface of the branch pipe. The second rotating shaft is fixedly connected to the surface of the movable ring and is rotatably connected to the inner side of the movable frame.

[0012] The docking assembly includes a connector, a limiting ring, a first coupling, a second coupling, an outer ring groove, a spring-loaded lever, an outer limiting tube, and a first spring. The connector is fixedly connected to the end face of the main spray pipe, the limiting ring is fixedly sleeved on the side of the connector, the first coupling is fixedly connected to the end of the connector away from the main spray pipe, the second coupling is movably docked with the surface of the first coupling, and the end of the second coupling away from the first coupling is fixedly connected to the end face of the nozzle. The outer ring groove is formed on the side of the second coupling, the spring-loaded lever is fixedly connected to the end face of the connector and located outside the first coupling, and the locking head of the spring-loaded lever is movably locked inside the outer ring groove. The outer limiting tube is movably sleeved on the side surface of the connector and limited by the limiting ring, one end of the outer limiting tube extends to the position of the second locking head, the side of the spring-loaded lever is movably connected to the inner wall of the outer limiting tube, and the first spring is movably sleeved on the surface of the connector, with both ends of the first spring connected to the protruding position of the connector and the end face of the outer limiting tube, respectively.

[0013] A sealing seat is provided on the side of the first pair of connectors, and a sealing ring is provided on the side of the sealing seat near the second pair of connectors. When the second pair of connectors is movably connected to the first pair of connectors, the second pair of connectors is movably connected to the sealing ring. A second spring is movably sleeved on the surface of the connector at the position of the inner wall of the outer limiting tube. The two ends of the second spring are movably connected to the side of the limiting ring near the second pair of connectors and the inner wall of the outer limiting tube near the second pair of connectors, respectively.

[0014] The beneficial effects of this utility model are:

[0015] By setting up branch pipes and fixed brackets, the branch pipes and the main spraying pipe form a three-pipe structure, and the three nozzles are designed in a fan shape. In this way, the three branch pipes and three nozzles directly cover the area on both sides of the main spraying pipe, which greatly improves the spraying coverage. This solves the problem in the existing technology where there is only one nozzle, which results in insufficient pesticide spraying coverage and requires manual shaking of the nozzle to make it fan-shaped and reciprocate to increase the pesticide spraying range, thus reducing the pesticide spraying efficiency.

[0016] By setting an angle adjustment component, the movement of the angle adjustment component on the surface of the main spray pipe will cause the branch pipe to rotate around the first pivot on the fixed frame. When the angle adjustment component moves towards the nozzle, it will reduce the angle between the branch pipe and the main spray pipe, and vice versa, it will increase the angle between the branch pipe and the main spray pipe, thereby achieving the purpose of adjusting the spray range of the nozzle by adjusting the angle between the branch pipe and the main spray pipe.

[0017] By setting up docking components, the purpose of quickly installing and replacing the nozzles can be achieved. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-5 In this embodiment, the medicine box body 1 and the nozzle 2 are included. A handle 3 is fixedly connected to the side of the medicine box body 1 through a flexible tube. A main spray pipe 4 is provided at the other end of the handle 3. A branch pipe 5 is fixedly connected to the surface of the main spray pipe 4 through a flexible connecting tube. A fixing frame 6 is fixedly sleeved on the surface of the main pipe corresponding to the position of the branch pipe 5. The branch pipe 5 is set on the fixing frame 6.

[0027] The number of branch pipes 5 is two sets, and the two sets of branch pipes 5 are symmetrically arranged on both sides of the main spraying pipe 4. The surface of the branch pipe 5 is provided with a first rotating shaft 8, which is rotatably connected to the lower surface of the fixing frame 6 near the end face.

[0028] The branch pipe 5 and the main spray pipe 4 are provided with a docking component 7 at the end away from the handle 3, and the nozzle 2 is provided on the docking component 7.

[0029] In practice, the number of nozzles 2 is the same as the sum of the number of branch pipes 5 and the main spraying pipe 4. Then, the nozzles 2 are installed on the end faces of the branch pipes 5 and the main spraying pipe 4 through the docking assembly 7. The fixing bracket 6 is used to position and stabilize the branch pipes 5. The two sets of branch pipes 5 and the main spraying pipe 4 form a fan shape, which greatly increases the spraying area of ​​the nozzles 2, so that both sides of the main spraying pipe 4 are covered, and there is no need to shake a nozzle 2 to carry out spraying operations.

[0030] refer to Figure 1-5In this embodiment, the surface of the main spraying pipe 4 is movably fitted with an angle adjusting member 9 for adjusting the angle between the branch pipe 5 and the main spraying pipe 4. The angle adjusting member 9 includes a movable frame 10, a movable block 11, a damping ring 12, a movable ring 13, and a second rotating shaft 14. The damping ring 12 is fixedly connected to the inner wall of the movable block 11, and the movable block 11 is movably fitted onto the surface of the main spraying pipe 4 through the damping ring 12. The movable frame 10 is fixedly connected to the surface of the movable block 11, the movable ring 13 is movably fitted onto the surface of the branch pipe 5, and the second rotating shaft 14 is fixedly connected to the surface of the movable ring 13. The second rotating shaft 14 is rotatably connected to the inner side of the movable frame 10.

[0031] In practice, the movable frame 10 moves, which in turn causes the damping ring 12 to move along the surface of the main spray pipe 4 via the movable block 11. The movement of the movable frame 10 also causes the movable rings 13 at both ends to move along the surface of the branch pipes 5. When the movable frame 10 moves closer to the nozzle 2, the branch pipes 5 on both sides are pulled closer to the main spray pipe 4, thus reducing the angle between the main spray pipe 4 and the branch pipes 5. This closer movement of the branch pipes 5 causes the nozzles 2 on the branch pipes 5 to move closer to the nozzles 2 on the main spray pipe 4, thereby shortening the coverage area of ​​the nozzles 2. When the movable frame 10 moves towards the handle 3, it will open the branch pipe 5. It should be noted that the branch pipe 5 moves around the first pivot 8. The movement of the movable frame 10 will open the branch pipe 5, causing the two sets of branch pipes 5 to move away from the main spraying pipe 4, thereby increasing the angle between the branch pipe 5 and the main spraying pipe 4. This will cause the nozzle 2 on the branch pipe 5 to move away from the nozzle 2 on the main spraying pipe 4, thus increasing the coverage area of ​​the nozzle 2. This achieves the purpose of further adjusting the coverage area of ​​the nozzle 2 by adjusting the angle between the branch pipe 5 and the main spraying pipe 4.

[0032] refer to Figure 1-5In this embodiment, the docking assembly 7 includes a connector 15, a limiting ring 16, a first mating connector 17, a second mating connector 18, an outer ring groove 19, a spring lever 20, an outer limiting tube 21, and a first spring element 22. The connector 15 is fixedly connected to the end face of the spraying main pipe 4, the limiting ring 16 is fixedly sleeved on the side of the connector 15, the first mating connector 17 is fixedly connected to the end of the connector 15 away from the spraying main pipe 4, the second mating connector 18 is movably mated to the surface of the first mating connector 17, and the end of the second mating connector 18 away from the first mating connector 17 is fixedly connected to the end face of the nozzle 2. The outer ring groove 19... A spring-loaded lever 20 is fixedly connected to the end face of the connector 15 and located outside the first connector 17 on the side of the second connector 18. The locking head of the spring-loaded lever 20 is movably locked inside the outer ring groove 19. The outer limiting tube 21 is movably sleeved on the side surface of the connector 15 and limited by the limiting ring 16. One end of the outer limiting tube 21 extends to the position of the second locking head. The side of the spring-loaded lever 20 is movably connected to the inner wall of the outer limiting tube 21. The first spring member 22 is movably sleeved on the surface of the connector 15, and the two ends of the first spring member 22 are respectively connected to the protruding position of the connector 15 and the end face of the outer limiting tube 21.

[0033] In practice, when it is necessary to remove the nozzle 2, taking the removal of the nozzle 2 on the main spray pipe 4 as an example, firstly, the outer limiting tube 21 needs to be moved. Moving the outer limiting tube 21 towards the main spray pipe 4 will compress the first spring member 22. While compressing the first spring member 22, the outer limiting tube 21 will move away from the elastic locking rod 20, allowing the elastic locking rod 20 to bend freely. Then, force is applied to the side away from the connector 15 to move the nozzle 2, causing the nozzle 2 to separate from the outer ring groove 19 by compressing the elastic locking rod 20. This allows the nozzle 2 to be quickly removed, achieving the effect of quickly removing the nozzle 2 for replacement or maintenance. During installation, due to the elastic force of the first spring member 22, the outer limiting tube 21 will also be locked again. The outer side of the spring clamp 20 is used as the starting point. Therefore, the outer limiting tube 21 is moved first, and then the outer limiting tube 21 is moved to separate from the spring clamp 20. Then, the second connector 18 on the nozzle 2 is connected to the first connector 17. During the connection, the second connector 18 squeezes the spring clamp 20 and bends it until it is locked in the outer ring groove 19. Then, the outer limiting tube 21 is released. At this time, the outer limiting tube 21 is sleeved on the side of the spring clamp 20 by the elastic force of the first spring 22. After the position of the spring clamp 20 is limited, it cannot bend or move. In this way, the spring clamp 20 and the outer limiting tube 21 work together to stably connect the first connector 17 to the second connector 18, so as to quickly install the nozzle 2 and reduce the operation time caused by maintenance or replacement of the nozzle 2.

[0034] refer to Figure 1-5In this embodiment, a sealing seat is provided on the side of the first connector 17, and a sealing ring is provided on the side of the sealing seat near the second connector 18. When the second connector 18 is movably connected to the first connector 17, the second connector 18 is movably connected to the sealing ring. The surface of the connector 15 is movably sleeved with a second spring member 23 at the position of the inner wall of the outer limiting tube 21. The two ends of the second spring member 23 are movably connected to the side of the limiting ring 16 near the second connector 18 and the inner wall of the outer limiting tube 21 near the second connector 18, respectively.

[0035] In specific implementation, the sealing seat is used to position the sealing ring. After the first connector 17 and the second connector 18 are stably mated, the end face of the second connector 18 is tightly attached to the surface of the sealing ring. This ensures a good seal at the connection between the second connector 18 and the first connector 17, preventing leakage. Furthermore, a sealing gasket is also provided at the mating position of the first connector 17 and the second connector 18 to improve the sealing between them, thereby stabilizing the connection of the nozzle 2. The purpose of the second spring member 23 is to increase the elasticity of the outer limiting tube 21, ensuring that the outer limiting tube 21 has sufficient elasticity to stably fit around the outside of the elastic lever 20 and limit its movement.

[0036] The method of using this utility model is as follows:

[0037] During operation, the angle adjustment component 9 is moved, causing the movable block 11 on the angle adjustment component 9 to move on the surface of the main spraying pipe 4 via the damping ring 12. Since the length of the movable frame 10 remains unchanged, the movement of the angle adjustment component 9 will drive the branch pipe 5 to rotate around the first rotating shaft 8, thereby adjusting the angle between the branch pipe 5 and the main spraying pipe 4, and thus adjusting the distance between the three nozzles 2, thereby adjusting the coverage area sprayed by the nozzles 2. When removing the nozzles 2, the outer limit tube 21 is moved directly, and then the nozzles 2 are moved so that the nozzles 2 are separated from the spring clamp 20 by squeezing the spring clamp 20, thereby quickly removing the nozzles 2. During installation, the movement is reversed in the same way, achieving the purpose of quickly and conveniently removing and installing the nozzles 2, facilitating the maintenance and repair of the nozzles 2.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
