Description

Technical Field

[0001] This invention relates to the field of pest and disease control equipment technology, and in particular to a forest pest and disease control device. Background Technology

[0002] Pest and disease control is the human effort to reduce or prevent the damage of pathogenic microorganisms and pests to crops or livestock. It can generally be divided into chemical control using chemical substances such as insecticides and physical control using physical energy such as light or radiation or by building barriers.

[0003] Chemical control is a method of controlling pests and diseases using chemical pesticides. Its main advantages are rapid action, good effect, and ease of use. It can eliminate or control large-scale outbreaks of pests and diseases in a short period of time. Commonly used tools include insecticides and fungicides. However, in the current technology for controlling pests and diseases in forest trees, most methods involve spraying pesticides with drones or using trunk injection. However, the trunk injection method requires manual measurement of the tree's diameter and then injecting different amounts of pesticides according to the diameter, which is cumbersome and increases the workload of controlling tree pests and diseases.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0005] To address the aforementioned shortcomings, the present invention aims to provide a forest pest and disease control device.

This automatic measurement and quantitative application of pesticide solution reduces errors and procedures caused by manual control, simplifying the trunk-injection control process.

[0006] To achieve the above objectives, the present invention provides a forest pest and disease control device, comprising: a main frame, the top of which is slidably connected to two symmetrically arranged clamping heads for clamping trees; the top of the main frame is provided with a driving member for driving the two clamping heads to move towards each other; a container for holding pesticide solution disposed on the outside of the main frame; a sliding column slidably connected to the inside of the container of the clamping heads; the sliding column slidably controls the storage space of pesticide solution inside the container; a pesticide solution channel is opened inside the clamping heads; an injection head is provided at the front end of the clamping heads; the outlet of the pesticide solution channel is connected to the inlet of the injection head; a connecting hole is provided on the end side wall of the sliding column connecting the pesticide solution channel and the storage space; a first piston is slidably provided on the side wall of the storage space; the first piston pushes the pesticide solution through the injection head and injects it into the interior of the tree.

[0007] According to the forest pest and disease control device of the present invention, the interior of the accommodating cylinder is provided with a first sliding hole and a second sliding hole, the first sliding hole is located at one end near the clamping head, the diameter of the second sliding hole is larger than the diameter of the first sliding hole, and the end of the sliding column is provided with an annular protrusion that is in close contact with the inner wall of the first sliding hole.

[0008] According to the forest pest and disease control device of the present invention, a plug is slidably connected inside the second sliding hole, and a thrust spring is provided between the plug and the bottom of the second sliding hole. After the sliding column disengages from the first sliding hole, it pushes the plug to slide inside the second sliding hole.

[0009] According to the forest pest and disease control device of the present invention, a second piston is slidably connected inside the second sliding hole. The outer wall of the second piston is in close contact with the outer wall of the second sliding hole and the inner diameter of the piston corresponds to the diameter of the first sliding hole. A certain gap is provided between the second piston and the sliding column. When the first piston slides to fit with the second piston, the first piston and the second piston cooperate to seal the second sliding hole.

[0010] According to the forest pest and disease control device of the present invention, the inner wall of the first sliding hole is provided with a groove, the first piston is provided with a protrusion that cooperates with the groove, the side wall of the second piston is provided with a groove that cooperates with the protrusion, and a control hole is opened on the side wall of the first sliding hole near the clamping head. Positive or negative pressure fluid is introduced into the control hole to drive the first piston and the second piston to slide back and forth.

[0011] According to the forest pest and disease control device of the present invention, the driving component is a bidirectional screw, the clamping head is provided with a threaded hole, the two clamping heads are respectively threaded to the two sections of the bidirectional screw, and a rotary motor for driving the bidirectional screw to rotate is fixed on the main frame.

[0012] According to the forest pest and disease control device of the present invention, the top of the clamping head is provided with an injection port communicating with the liquid channel, the injection port is connected to the liquid supply mechanism, and the outlet is connected to the injection head through a flexible tube.

[0013] According to the forest pest and disease control device of the present invention, the clamping head includes an arc-shaped clamping part, the side wall of the arc-shaped clamping part is provided with an insertion hole inclined at 45° from the outside to the inside, and the injection head is inserted into the insertion hole.

[0014] According to the forest pest and disease control device of the present invention, the connecting pipe of the injection port is provided with an inlet control valve, and the connecting pipe of the outlet port is provided with an outlet control valve.

The sliding column slides to control the medicine storage space inside the receiving cylinder, ensuring that different amounts of medicine are injected into trees of different sizes. The inside of the clamping head is provided with a medicine channel, and the front end of the clamping head is provided with an injection head. The medicine is injected into the inside of the tree through the injection head. The outlet of the medicine channel is connected to the inlet of the injection head.

[0019] 4. By setting up a clamping head that automatically measures the diameter of trees, the system ensures that when the clamping head clamps the tree, it automatically dispenses the corresponding amount of pesticide according to the position of the clamping head, and then injects the corresponding amount of pesticide into the tree.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0031] See Figures 1-7This invention provides a forest pest and disease control device, which includes a main frame 1 with two symmetrically arranged clamping heads 5 slidably connected to its top. The clamping heads 5 clamp the tree at the location where drilling and injection are needed, automatically detecting the tree's diameter and reducing the need for manual measurement with a measuring tape. The top of the main frame 1 is equipped with a drive unit that moves the two clamping heads 5 towards each other, clamping the tree. A container 11 for holding pesticide solution 9 is located outside the main frame 1. The container 11 allows the clamping heads 5 to slide, controlling the size of the pesticide storage space. A sliding column 56 is slidably connected to the inside of the container 11 on the outside of the clamping heads 5. The sliding column 56 controls the pesticide storage space inside the container 11, ensuring that different sizes of trees can be injected with different solutions. The clamping head 5 has a liquid medicine channel 58 inside, and an injection head 4 is provided at the front end of the clamping head 5. The liquid medicine 9 is injected into the tree through the injection head 4. The outlet 55 of the liquid medicine channel 58 is connected to the inlet of the injection head 4. The end side wall of the sliding column 56 is provided with a connecting hole 57 that connects the liquid medicine channel 58 and the storage space. By setting the connecting hole 57, it is ensured that the storage space and the liquid medicine channel 58 can be connected, and further ensures the supply of liquid medicine 9 to the injection head 4. The side wall of the storage space is provided with a first piston 8. The first piston 8 pushes the liquid medicine 9 through the injection head 4 and injects it into the tree, thereby realizing the quantitative supply of liquid medicine 9 to the injection head 4. The connecting pipe of the injection port 54 is provided with a feed control valve, and the connecting pipe of the outlet 55 is provided with a discharge control valve. The feed control valve and the discharge control valve work together to control the feeding and discharging process inside the liquid medicine channel 58.

[0032] Preferably, the accommodating cylinder 11 of the present invention has a first sliding hole 13 and a second sliding hole 12 inside. By setting two sliding holes, it is ensured that during use, since the trees are 10 cm in diameter, the amount of additional medicine 9 required for each additional centimeter of diameter increases differs between trees larger than 10 cm and trees smaller than 10 cm. This ensures that when the first sliding hole 13 is inside, it is suitable for small-diameter trees, while when clamping larger-diameter trees, the flange of the sliding post 56 will enter the second sliding hole 12, thus controlling the amount of medicine 9. The first sliding hole 13 is located near the end of the clamping head 5, and the diameter of the second sliding hole 12 is larger than the diameter of the first sliding hole 13. The end of the sliding post 56 has an annular protrusion that fits tightly against the inner wall of the first sliding hole 13, ensuring that the amount of medicine 9 is controlled within the first sliding hole 13. When the first sliding hole 13 is inside, the annular protrusion can seal the first sliding hole 13, ensuring that the amount of medicine 9 can be controlled. A sealing plug 6 is slidably connected inside the second sliding hole 12. A thrust spring 15 is provided between the sealing plug 6 and the bottom of the second sliding hole 12. Under the action of the thrust spring 15, the sealing plug 6 abuts against the annular protrusion, ensuring the sealing of the other side of the sealing plug 6. At the same time, after the sliding column 56 disengages from the first sliding hole 13, it pushes the sealing plug 6 to slide inside the second sliding hole 12. At this time, the tree is exactly 10 cm or more in diameter, thereby controlling the increase of medicine 9. At the same time, the medicine storage space is the space formed by the gap between the sliding column 56 and the first sliding hole 13 and the second sliding hole 12. The inner wall of the first sliding hole 13 is in close contact with the outer wall of the annular protrusion, ensuring the sealing effect of various sliding parts.

[0033] In addition, a second piston 7 is slidably connected inside the second sliding hole 12 of the present invention. The outer wall of the second piston 7 is in close contact with the outer wall of the second sliding hole 12, and the inner diameter of the second piston 7 corresponds to the diameter of the first sliding hole 13. This ensures that the second piston 7 blocks the second sliding hole 12. At the same time, it ensures that when the first piston 8 is disengaged from the first sliding hole, the first piston 8 can be engaged with the second piston 7, forming a process of blocking the gap between the sliding column 56 and the second sliding hole 12 and pushing the material. A certain gap is provided between the second piston 7 and the sliding column 56 to ensure that the annular protrusion of the sliding column 56 can slide inside the second piston 7 during use, preventing the sliding column 56 from driving the second piston 7 to move. When the first piston 8 slides to fit with the second piston 7, the first piston 8 and the second piston 7 cooperate to block the second sliding hole 12. At the same time, a sealing hole 16 is provided at the end of the first sliding hole 13 to fit with the outer wall of the sliding column 56, preventing the liquid medicine 9 from leaking from the gap between the sliding column 56 and the first sliding hole 13, thus affecting the amount of liquid medicine 9.

[0034] See Figures 1-5 , Figure 8 and Figure 9Furthermore, the inner wall of the first sliding hole 13 of the present invention is provided with a sliding groove, and the first ring body 81 on the first piston 8 is provided with a protrusion 82 that cooperates with the sliding groove, ensuring that the first ring body 81 can tightly seal the entire first sliding hole 13. The side wall of the second piston 7 is provided with a groove 71 that cooperates with the protrusion 82. By setting the protrusion 82 and the groove 71, it is ensured that the annular protrusion can pass through the second ring body 72 of the second piston 7, preventing the second piston 7 from interfering with the annular protrusion. The side wall of the first sliding hole 13 near the clamping head 5 is open. A control hole 14 is provided. Positive or negative pressure fluid is introduced into the control hole 14 to drive the first piston 8 and the second piston 7 to slide back and forth. When the storage space is filled with liquid medicine 9, high pressure fluid (which can be liquid or gas) is introduced into the control hole 14 to push the first piston 8 to slide inside the first sliding hole 13. The liquid medicine 9 inside the storage space is directly pushed into the outlet 55 through the connecting hole 57 and injected into the tree through the injection head 4 inside the insertion hole 51, completing the trunk injection prevention process.

[0035] Even better, the driving component of the present invention is a bidirectional screw 2, and the clamping head 5 is provided with a threaded hole 53. The two clamping heads 5 are respectively threaded to the two sections of the bidirectional screw 2. A rotary motor 3 for driving the bidirectional screw 2 to rotate is fixed on the main frame 1, which ensures that the arc-shaped clamping parts 52 of the two clamping heads 5 can be driven by the rotary motor 3 to clamp the tree. At the same time, a torsion bearing can be provided between the bidirectional screw 2 and the drive shaft of the rotary motor to ensure that the bidirectional screw 2 stops rotating after the clamping head 5 clamps the tree.

[0036] Furthermore, the top of the clamping head 5 of the present invention is provided with an injection port 54 communicating with the liquid channel 58. The injection port 54 is connected to the liquid supply mechanism 9 to ensure the supply of liquid 9 to the inside of the storage space. The outlet 55 is connected to the injection head 4 through a flexible tube to prevent affecting the movement of the clamping head 5. The clamping head 5 includes an arc-shaped clamping part 52. The side wall of the arc-shaped clamping part 52 is provided with an insertion hole 51 that is inclined at 45° from the outside to the inside. After clamping, the injection head 4 can be pulled out and then a hole can be drilled in the tree facing the insertion hole 51 to ensure the drilling angle. At the same time, after drilling, the injection head 4 can be directly inserted to complete the injection of the liquid 9 inside. Alternatively, a hole can be drilled first, and then the insertion hole 51 can be clamped in the tree facing the hole to ensure that the injection head 4 is inserted into the insertion hole 51 and the inside of the drilled hole.

[0037] In this embodiment, combined with Figures 1-9When in use, the device can be directly installed on a mobile trolley or a handheld device. When injecting medicine into trees, if the diameter of the tree is less than 10 cm, the clamping head 5 clamps the tree, and the annular protrusion at the end of the sliding column 56 is inside the first sliding hole 13. After clamping, the space for the medicine liquid 9 is the storage space between the inner side of the annular protrusion, the outer side of the sliding column 56, and the inner side of the sliding hole. When pushing the material, the first piston 8, under the action of positive pressure fluid, directly pushes the liquid inside the space into the injection head 4. At the same time, it stops moving under the restriction of the inner wall of the annular protrusion, completing the high-pressure injection process into the tree. Even if the medicine liquid 9 leaks from the chute to other positions, since those other positions are also filled with medicine liquid 9, the first piston 8 will only force the medicine liquid 9 in the corresponding area into the injection head 4. When resetting, the medicine liquid 9 will flow back to its original position and will not affect the subsequent use of the clamping head 5 and the medicine liquid 9.

[0038] When the diameter of the tree is greater than 10cm, the annular protrusion of the sliding column 56 will disengage from the inside of the first sliding hole 13 and enter the second sliding hole 12. At this time, the sliding column 56 abuts against the sealing head 6. Under the pushing action of the sliding column 56, the sealing head 6 compresses the thrust spring 15, and the increase in the unit displacement of the liquid medicine 9 changes to adapt to the needs of the liquid medicine 9 for larger trees. During the feeding process, the first piston 8 moves to abut against the second piston 7. In order to ensure the integrity of the first piston 8 and the second piston 7, the first piston 8 and the second piston 7 can be made of the same material to ensure the adsorption effect between them. By moving the first piston 8 and the second piston 7 synchronously, the liquid medicine 9 located inside the first sliding hole 13 and the second sliding hole 12 is directly pressed into the injection head 4 to complete the effect of injecting medicine into the tree. During the reset, the inside of the control hole 14 is drawn into negative pressure, and the first piston 8 and the second piston 7 are reset to their initial positions under the action of negative pressure.

[0039] In summary, this invention provides a forest pest and disease control device, comprising: a main frame, the top of which is slidably connected to two symmetrically arranged clamping heads for holding trees. The two clamping heads clamp the location on the tree where drilling and injection are required, thereby automatically detecting the tree's diameter and reducing the manual steps required for measuring with a measuring tape. The top of the main frame is provided with a driving component that drives the two clamping heads to move towards each other, thereby clamping the tree. A container for holding pesticide solution is located on the outside of the main frame. This container allows the clamping heads to slide, controlling the size of the pesticide storage space. A sliding column is slidably connected to the outside of the clamping heads and inside the container. The sliding column controls the pesticide storage space inside the container, ensuring that different amounts of pesticide solution are injected into trees of different sizes. A pesticide channel is provided inside the clamping heads. The clamping head has an injection head at its front end, through which liquid medicine is injected into the tree. The outlet of the liquid medicine channel is connected to the inlet of the injection head. The end side wall of the sliding column has a connecting hole that connects the liquid medicine channel and the storage space. By setting the connecting hole, the storage space and the liquid medicine channel can be connected, further ensuring the supply of liquid medicine to the injection head. The side wall of the storage space is slidably equipped with a first piston. The first piston pushes the liquid medicine through the injection head into the tree, thereby realizing the quantitative supply of liquid medicine to the injection head. In summary, the technical effect of this invention is that by setting a clamping head that automatically measures the diameter of the tree, it ensures that when the clamping head clamps the tree, it automatically prepares the corresponding amount of liquid medicine according to the position of the clamping head, and then injects the corresponding amount of liquid medicine into the tree. This completes the automatic measurement and quantitative liquid medicine supply, reduces the error of human control of the amount and the process, and simplifies the steps of trunk injection for prevention and control.
