Abstract
Description
Technical Field
[0001] This invention belongs to the field of forestry pest and disease control technology, and in particular relates to a perforation and injection device for the control of fruit tree pests and diseases. Background Technology
[0002] Injection of pesticides through perforation is a common method for controlling pests and diseases in fruit trees. It is mainly used to control pests and diseases inside the fruit tree. Pesticides can be directly injected into the wood of the fruit tree, allowing them to be quickly transported to the affected areas, thus having a rapid and direct effect on pests and diseases and improving the control effect. It can also be used to directly inject pesticides into parts of the fruit tree that are difficult to spray, in order to kill insects, kill bacteria, or regulate the growth of the fruit tree. Compared with spraying pesticides, injection of pesticides through perforation can reduce pesticide waste and also reduce environmental pollution.
[0003] Existing drilling and injection devices generally include two types. One type separates the drilling bit and the injection pipe. In use, a hole is first drilled, and then the pesticide is injected through the injection pipe. However, this method is cumbersome, involves repetitive steps, reduces injection efficiency, and increases the workload. The other type has a discharge hole on the side wall of the drill bit, and the pesticide is injected through the drill bit that drills into the fruit tree. However, the discharge time of this method is not easy to control, which can easily lead to waste of pesticide and also poses a risk of poisoning to the operator. Furthermore, the discharge hole on the drill bit is prone to blockage, resulting in abnormal pesticide dispensing and affecting the use of the device.
[0004] Therefore, this application designs a perforation and injection device for the prevention and control of fruit tree diseases and pests to solve the above-mentioned technical problems. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] Reference Figures 1-6 As shown, this embodiment provides a perforation and injection device for the control of fruit tree diseases and pests, comprising:
[0032] The main body 1 is provided with a liquid storage cylinder 11 for storing liquid medicine. The liquid storage cylinder 11 is divided into a liquid storage chamber 13 and a cavity 14 by a slidingly disposed first piston 12. The main body 1 is provided with a driving component for drilling.
[0033] The drill rod 2 includes a connecting rod 21 that extends into the main body 1 and is connected to the drive assembly for transmission. The connecting rod 21 has a liquid guiding groove 22 that communicates with the liquid storage cylinder 11. A prism-shaped transmission rod 23 is provided at the end of the connecting rod 21 away from the drive assembly. The transmission rod 23 has a liquid outlet hole 24 that communicates with the liquid guiding groove 22. A drill bit 25 is provided on the upper sliding sleeve of the transmission rod 23. The drill bit 25 is detachably connected to the liquid outlet hole 24.
[0034] The power unit 3 includes a power cylinder 31 installed on the liquid storage cylinder 11, which is connected to the cavity 14; a slide rod 32 is slidably installed inside the power cylinder 31, which extends out of the power cylinder 31 and is in contact with the surface of the fruit tree.
[0035] This invention discloses a drilling and injection device for controlling fruit tree diseases and pests. The main body 1 serves as the foundation of the device, exhibiting good integration. The drive component rotates the drill rod 2, which then drills into the fruit tree. The power unit 3 provides power for the injection process of the drill rod 2. When the drill rod 2 drills, the drill bit 25 slides along the transmission rod 23, blocking the liquid outlet 24 to prevent the liquid from leaking out during drilling, thus ensuring the accuracy of injection. When the hole is pulled out after reaching the specified depth, the transmission rod 23 and the drill bit 25 slide to expose the liquid outlet 24, allowing the liquid to be discharged, ensuring that the liquid is all within the drill hole and reducing liquid waste. When drilling into the fruit tree, the sliding rod 32 contacts the surface of the fruit tree, causing the sliding rod 32 to slide within the power cylinder 31, thereby pushing the first piston 12 in the liquid storage cylinder 11 to discharge the liquid from the liquid storage cylinder 11, facilitating injection. This allows drilling and injection to be performed simultaneously, eliminating the need for separate operations, improving injection efficiency, and reducing labor consumption. This invention has a simple structure and is easy to use. It can complete drilling and injection in one go, improving work efficiency. At the same time, it ensures that the injected liquid is all inside the borehole, reducing liquid waste and minimizing the impact of the liquid on the operator.
[0036] Furthermore, a liquid inlet ring 18 is provided on one side of the main body 1, which surrounds the transmission rod 23. The drive rod is sealed to the liquid inlet ring 18, so that the liquid inlet hole 212 in the liquid inlet ring 18 enters the liquid guide groove 22, thereby realizing the injection of medicine into the drill rod 2.
[0037] Furthermore, the side wall of the medicine storage cylinder is provided with an inlet pipe 19 that communicates with the inner cavity of the liquid storage chamber 13. After passing through the third one-way valve 110, it communicates with the inner cavity of the inlet ring 18. When the first piston 12 moves, it pushes the liquid medicine in the liquid storage chamber 13 into the inlet ring 18.
[0038] Furthermore, the bottom end of the inlet ring 18 is provided with a discharge valve 215 for discharging residual medicine, which facilitates the discharge of residual medicine after the injection is completed, and also facilitates cleaning of the inlet ring 18.
[0039] In a further optimized design, the drill bit 25 has a transmission groove 26 adapted to the transmission rod 23. The transmission rod 23 is slidably disposed within the transmission groove 26, and the transmission groove 26 is detachably connected to the liquid outlet 24. A clearance groove 27 is connected to the end of the transmission groove 26 away from the transmission rod 23. The transmission rod 23 extends into the clearance groove 27 and is fixedly connected to an end block 28 that slidably dissipates within the clearance groove 27. A first spring 29 is fixedly connected between the end block 28 and the clearance groove 27. When drilling, the end of the drill bit 25 contacts the fruit tree and is subjected to force, causing the transmission rod 23 to slide within the transmission groove 26. This, in turn, blocks the liquid outlet 24 through the transmission groove 26, preventing the liquid from leaking out during incomplete drilling. The end block 28 within the clearance groove 27 slides, preventing the transmission groove 26 from separating from the transmission rod 23. The first spring 29 is used to separate the transmission rod 23 and the transmission groove 26, ensuring that the transmission groove 26 releases the liquid outlet 24 when the drill bit 25 is not under force.
[0040] In a further optimized design, a sealing gasket 210 is installed inside the transmission groove 26. The inner wall of the sealing gasket 210 is interference-fitted with the outer wall of the transmission rod 23 and slidably disposed. A sealing block 211 adapted to the liquid outlet 24 is provided on the inner wall of the sealing gasket 210. The sealing block 211 is detachably connected to the liquid outlet 24. The sealing gasket 210 is made of flexible material, which serves to support the transmission rod 23 and improve the stability of the transmission rod 23. After the transmission rod 23 is subjected to force and extends into the transmission groove 26, the sealing block 211 inside the sealing gasket 210 is positioned corresponding to the liquid outlet 24 and seals the liquid outlet 24.
[0041] Further optimizing the design, the slide bar 32 includes an outer rod 33 slidably disposed within the power cylinder 31, extending out of the power cylinder 31. An inner rod 34 is telescopically disposed within the inner cavity of the outer rod 33. The end of the inner rod 34 furthest from the power cylinder 31 extends out of the outer rod 33 and is fixedly connected to a contact block 35, which contacts the surface of the fruit tree. The slide bar 32 is configured with two parts: the inner rod 34 and the outer rod 33. The outer rod 33 slides within the power cylinder 31, while the inner rod 34 slides within the inner cavity of the outer rod 33. This allows for easy adjustment of the overall length of the slide bar 32, thereby adjusting the drilling depth of the contact block 35 after contact, making it suitable for use with different fruit trees.
[0042] Furthermore, a locking cylinder 313 is provided at the end of the outer rod 33, which can realize the movement and locking of the inner rod 34 and the outer rod 33, and facilitate the adjustment of the length of the slide rod 32. For details, please refer to the rod of a conventional floor fan, which will not be elaborated here.
[0043] Furthermore, the end of the contact block 35 facing the fruit tree is provided with an arc-shaped contact surface, and a contact pad 36 is attached to the contact surface to prevent the contact block 35 from damaging the bark of the fruit tree.
[0044] In a further optimized design, a power chamber 37 is formed inside the power cylinder 31. An outer rod 33 extends into the power chamber 37 and is fixedly connected to a second piston 38. The second piston 38 is in a sealed sliding contact with the inner wall of the power chamber 37. A second spring 39 is fixedly connected between the second piston 38 and the bottom end of the power chamber 37. When the contact block 35 contacts the fruit tree, the outer rod 33 pushes the second piston 38 to slide within the power chamber 37, thereby compressing the air inside the power cylinder 31. This compressed air then enters the cavity 14, increasing the pressure within the cavity 14 and pushing the first piston 12 to move and discharge the pesticide. The second spring 39 is used to push the second piston 38 back to its original position, facilitating the reset of the contact block 35 after each injection, preventing interference with subsequent use.
[0045] In a further optimized design, the end of the power chamber 37 furthest from the outer rod 33 is connected to a three-way hole 310 located inside the power cylinder 31. One outlet of the three-way hole 310 is connected to the power chamber 37, and the other outlet of the three-way hole 310 is connected to a first one-way valve 311 located at the end of the power cylinder 31. After compressed air enters the three-way hole 310, it opens the second one-way valve 312 and enters the cavity 14, causing the pressure inside the cavity 14 to increase, thereby pushing the first piston 12 to facilitate the discharge of the liquid medicine. When the second piston 38 returns to its original position, the first one-way valve 311 on the power cylinder 31 opens, while the second one-way valve 312 closes, making the air pressure inside the power chamber 37 the same as the outside pressure.
[0046] Further optimization of the design involves a support rod 15 mounted on the main body 1, with a support ring 16 at the top of the support rod 15. The support ring 16 is slidably fitted onto the outer wall of the inner rod 34. A bottom ring 17 is fixedly connected to the side wall of the liquid inlet ring 18, and the support ring 16 is fixedly connected to the bottom ring 17 via the support rod 15. The support ring 16 is fitted onto the outer wall of the inner rod 34, thereby improving the stability of the slide rod 32.
[0047] Further optimizing the design, the drive assembly includes a drive motor 111 and counterweights 112. The drive motor 111 is located inside the main body 1 and is connected to the connecting rod 21 for transmission. A ventilated protective cover 113 is provided at the end of the main body 1 away from the transmission rod 23, and the counterweights 112 are axially and equally spaced on the inner wall of the ventilated protective cover 113. The drive motor 111, located inside the main body 1, drives the drill rod 2 to rotate, providing drilling power; while the counterweights 112 inside the ventilated protective cover 113 are used to balance the center of gravity of the device and prevent the device from becoming too heavy; the ventilated protective cover 113 also improves the heat dissipation and ventilation performance of the main body 1, ensuring the operational stability of the equipment.
[0048] Further optimizing the design, a mounting box 114 is installed at the bottom of the main body 1. Inside the mounting box 114 is a control module 115 electrically connected to the drive motor 111. The control module 115 is also electrically connected to a control button 116 located at the bottom of the main body 1. A battery module 117 is detachably connected to the bottom of the mounting box 114, and the battery module 117 is electrically connected to the control module 115. The control module 115 inside the mounting box 114 controls the operation of the drive motor 111, which is controlled via the control button 116. The battery module 117 is detachably connected to the bottom of the mounting box 114 and supplies power to the drive module and the drive motor 111. The battery module 117 is easily removable and replaceable, increasing its service life and facilitating large-area drilling and injection. Furthermore, the battery module 117 is removable and rechargeable, allowing for the preparation of multiple spare batteries.
[0049] In a further optimized design, a drill bit 213 is provided at the end of the drill bit 25 furthest from the transmission rod 23 to facilitate drilling into the fruit tree. Several cutting edges 214 are axially spaced evenly on the outer wall of the drill bit 25. The drill bit 213 enhances the drilling capability of the drill bit 25, while the cutting edges 214 cut and enlarge the hole through the rotation of the drill bit 25, providing space for the chemical solution; simultaneously, they prevent the chemical solution from being carried out when the drill bit 25 is pulled out, reducing waste.
