Description

Technical Field

[0001] This utility model relates to pine wilt disease control equipment in the field of forestry technology, specifically a device for controlling pine wilt disease. Background Technology

[0002] In existing technologies, pine wilt disease is a devastating disease of pine trees, often referred to as "pine cancer." It is primarily caused by the parasitic pine wilt nematode and mainly affects pine species. The main method of controlling pine wilt disease in existing technologies is through pesticide spraying, with particular emphasis on affected areas of the pine trunk and branches. Many common pesticide spraying techniques exist; for example, the "pesticide spraying device for controlling pine wilt disease" disclosed in patent announcement number CN223379896U, uses an arc-shaped structure and a vertical box. A sliding block slides on a guide rod, facilitating adjustment of the height of the vertical box and nozzle to accommodate spraying at different heights on the trunk. A third motor drives the arc-shaped structure to adjust the tilt angle of the vertical box and nozzle to accommodate tilted trunks. As the arc box slides inside the arc sleeve, it moves the vertical box and nozzle via a connecting pipe, allowing spraying to cover the outside of the trunk, thus increasing the coverage area and improving the practicality of the pesticide spraying device.

[0003] The above technical solutions mainly expand the coverage area by setting up nozzles and other technical means to achieve spraying at different heights and positions on the tree trunk; however, the method of expanding the coverage area in the above technical solutions will lead to inconcentrated spraying, which also has great drawbacks; especially when the diseased areas on the pine branches and trunks are difficult to spray, it will be very troublesome, and it is difficult to achieve the spraying of medicine in the diseased areas by simply adjusting the position or height in one direction.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a device for controlling pine wilt disease that has a reasonable structure and can be adjusted at multiple angles. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for controlling pine wilt disease; the technical solution is as follows:

[0006] A device for controlling pine wilt disease includes a pesticide back box and an electric actuator for use in conjunction with it. The main shaft of the electric actuator can extend and retract accordingly, and an adjustable spraying assembly is installed at the end of the main shaft. A strip-shaped groove is also installed on the side wall of the electric actuator. A spraying hose is installed at the bottom of the pesticide back box. The spraying hose is correspondingly embedded in the strip-shaped groove and is correspondingly connected to the adjustable spraying assembly.

[0007] Furthermore, the adjustable spraying assembly includes a cover, in which a spraying head is installed. Several adjusting screws are installed on the upper end of the cover, and adjusting plates are installed on the adjusting screws. Each adjusting screw is equipped with two adjusting nuts, which are located on the upper and lower sides of the adjusting plate, respectively. The adjusting plate is fixed to the adjusting screw by the adjusting nuts on the upper and lower sides, and an adjustment gap is left between the adjusting plate and the cover.

It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0031] like Figure 1 As shown, a device for controlling pine wilt disease includes a pesticide back box 15 and an electric push rod 16 used in conjunction with it. The main shaft 11 of the electric push rod 16 can extend and retract accordingly, and an adjustable spraying assembly 17 is installed at the end of the main shaft 11. A strip-shaped slot 18 is also installed on the side wall of the electric push rod 16. A spraying hose 14 is installed at the bottom of the pesticide back box 15. The spraying hose 14 is correspondingly embedded in the strip-shaped slot 18 and is correspondingly connected to the adjustable spraying assembly 17.

[0032] like Figure 4 and Figure 5 As shown, the adjustable spraying assembly 17 includes a cover 1, in which a spraying head 101 is installed. Several adjusting screws 2 are installed on the upper end of the cover 1, and adjusting plates 3 are installed on the adjusting screws 2. Two adjusting nuts 4 are installed on each adjusting screw 2. The two adjusting nuts 4 are located on the upper and lower sides of the adjusting plate 3, respectively. The adjusting plate 3 is fixed on the adjusting screw 2 by the adjusting nuts 4 on the upper and lower sides, and an adjustment gap 5 is left between the adjusting plate 3 and the cover 1.

[0033] A rotating seat 6 is also installed on the adjusting plate 3, and an adjusting rod 7 is installed on the rotating seat 6. The end of the adjusting rod 7 is connected to a hinge rod 9 via a rotating pin 8, and the hinge rod 9 is correspondingly installed at the end of the main shaft 11 of the electric push rod 16.

[0034] The hinge rod 9 and the main shaft 11 of the electric push rod 16 are connected to each other through the hinge assembly 10. The angle of the hinge rod 9 is adjusted accordingly through the hinge assembly 10. The adjustment direction of the hinge assembly 10 is perpendicular to the adjustment direction of the rotating pin 8. The hinge assembly 10 is adjusted in the vertical direction, and the rotating pin 8 is adjusted in the horizontal direction.

[0035] The spray head 101 is installed inside the cover 1, and a pipe joint 12 is also installed at the bottom of the cover 1. The spray hose 14 is detachably installed on the pipe joint 12, and the pipe joint 12 is connected to the spray head 101.

[0036] The bottom of the medicine back box 15 is equipped with a pipe joint 12, and the spray hose 14 is detachably installed on the pipe joint 12; there are four adjusting screws 2 on the cover 1.

[0037] like Figure 2 As shown, the electric push rod 16 has a square cross-section, and the strip groove 18 on the side wall of the electric push rod 16 has a semi-circular cross-section, with a vertical notch 19 on the top of the strip groove 18. The spray hose 14 is fitted into the strip groove 18 through the notch 19 and can be removed from the strip groove 18. The strip groove 18 is made of plastic.

[0038] like Figure 3 As shown, the hinge assembly 10 includes a U-shaped hinge seat 102 disposed at the upper end of the spindle, a hinge rod 9 correspondingly inserted into the hinge seat 102, and a hinge shaft 103 passing through the hinge rod 9 is correspondingly installed in the hinge seat 102.

[0039] Firstly, in the technical solution of this device, the pesticide back box 15 is the foundation of the overall structure. The pesticide back box 15 itself is an existing integrated structure. The inside of the pesticide back box 15 is equipped with a pressure device for delivering the pesticide, a power supply device for providing power, various control switches, and a carrying strap, etc. This is a common structural arrangement in the prior art. For example, the "Spraying Device for the Control of Pine Wilt Disease" disclosed in patent announcement number: CN 222382515 U and the "Device for the Elimination of Pine Wilt Disease" disclosed in patent announcement number: CN 219330500 U both have existing structural designs. Therefore, there is no corresponding detailed description of the structural arrangement of the pesticide back box 15 in this device. However, the main function of this device is to realize the angle adjustment problem when spraying pesticides to control pine wilt disease, and to spray the diseased area from multiple directions without dead angles.

[0040] The technical solution of this device firstly includes an adjustable electric push rod 16. The main shaft 11 of the electric push rod 16 can extend and retract accordingly. An adjustable spraying assembly 17 is installed at the end of the main shaft 11. Therefore, the height of the adjustable spraying assembly 17 at the upper end can be adjusted by extending and retracting the main shaft 11 of the electric push rod 16. The electric push rod 16 in this device is a common and frequently used height adjustment device in the prior art. It is a common device, so its structure is not described in detail. However, those skilled in the art should be able to understand how the electric push rod 16 achieves height adjustment.

[0041] Furthermore, in this device, the spray hose 14 and the electric push rod 16 used to guide the pesticide are set separately. The spray hose 14 can be connected to the adjustable spraying assembly 17, but the connection between the spray hose 14 and the electric push rod 16 is detachable. In this device, a strip-shaped groove 18 is provided on the side wall of the spray hose 14, and a notch 19 is provided on the strip-shaped groove 18. The spray hose 14 is inserted into the strip-shaped groove 18 through the notch 19. With this design, the spray hose 14 is properly inserted into the strip-shaped groove 18 and can be disassembled. When spraying pesticides, simply lift the electric push rod 16 to achieve pesticide spraying. Moreover, the electric push rod 16 in the prior art is designed to be very lightweight, making it easy to achieve pesticide spraying by lifting the electric push rod 16.

[0042] The technical solution of this device can not only adjust the spraying height, but also adjust many angles. First, the upper end of the main shaft 11 of the electric push rod 16 is equipped with a hinge rod 9 through the hinge assembly 10. The hinge assembly 10 includes a U-shaped hinge seat 102 set at the upper end of the main shaft 11. The hinge rod 9 is inserted into the hinge seat 102, and a hinge shaft 103 that passes through the hinge rod 9 is installed in the hinge seat 102. Then, the hinge rod 9 can be adjusted in angle with the cooperation of the hinge assembly 10. The hinge rod 9 and the adjusting rod 7 are connected by a rotating pin 8, so the angle of the adjusting rod 7 can be adjusted accordingly. The relationship between the rotating pin 8 and the adjustment direction of the hinge assembly 10 is perpendicular, so multi-angle adjustment can be achieved.

[0043] Furthermore, in this device, an adjusting plate 3 is installed on the upper end of the cover 1 via an adjusting screw 2 and an adjusting nut 4. Firstly, the position of the adjusting plate 3 can be adjusted accordingly, so that an adjusting gap 5 is formed between the adjusting plate 3 and the cover 1. Therefore, the position adjustment of the cover 1 can be achieved by setting the size of the adjusting gap 5, thereby achieving the position adjustment of the spray head inside the cover 1.

[0044] Furthermore, this device includes a rotating seat 6 on the adjusting plate 3, with an adjusting rod 7 embedded in the rotating seat 6. The rotating seat 6 and the adjusting rod 7 work together to adjust the rotation of the cover 1. The adjusting rod 7 is connected to a hinge rod 9 via a rotating pin 8, which can adjust the angle of the cover 1 and the spraying angle accordingly. Through the cooperation of the above components, the cover 1 can be adjusted in various directions, including tilt angle, length position, and rotation position, to adapt to spraying and pest control on pine branches and trunks at different positions and angles, effectively preventing and controlling pine wilt disease.

[0045] In addition, the specific technical solution of this device is to set up a specific connection between the spraying hose 14 and the spraying head inside the cover 1. First, the spraying hose 14 is embedded in the strip-shaped slot 18 and can be taken out from the strip-shaped slot 18. Both ends of the spraying hose 14 are also detachable. One end is connected to the lower end of the agent back box 15 through the pipe connector 12, and the other end is connected to the cover 1 through the pipe connector 12. With this setting, the spraying hose 14 can be disassembled and replaced. Moreover, the electric push rod 16 itself is not connected to the agent back box 15. Therefore, the components can be carried separately. In this device, the transverse cross section of the spraying hose 14 is set to be square, and the strip-shaped slot 18 is set to be semi-circular, so that the spraying hose 14 can be easily embedded in the strip-shaped slot 18. The structure is very ingenious and reasonable, which can be installed as a whole or set separately.

[0046] The device has spray heads installed inside the cover 1. The cover 1 is designed to concentrate the spraying area, making the pesticide spraying more focused. Multiple spray heads can be installed in the device, and each spray head needs to be connected to the pipe joint 12 on the cover 1 to achieve pesticide communication. At the same time, the various angles of the cover 1 can be adjusted so that the spray heads can be aimed at the diseased areas of the pine branches for concentrated disinfection and pest control.

[0047] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
