Description

Technical Field

[0001] This invention relates to the field of pine nematode disease control technology, and particularly to an injection device for pine nematode disease control. Background Technology

[0002] Pine wilt disease, also known as pine wilt, is a devastating forest disease caused by the pine wood nematode. The main vector insect for the pine wood nematode is the pine sawyer beetle. The pine wood nematode's entire reproductive cycle takes place inside the pine tree. When the vector insect carrying the pine wood nematode feeds on healthy pine branches or lays eggs, the nematode enters the pine tree and spreads the disease.

[0003] In the process of controlling pine wilt disease, it is necessary to drill holes in the tree trunks for injection. That is, drilling holes first and then injecting. After the existing injection equipment is used, a separate injection device is needed for injection. The process is cumbersome and reduces the efficiency of injection. Furthermore, when injecting in the field, workers cannot accurately judge the diameter of the pine tree, and therefore cannot accurately control the drilling depth. They also cannot accurately control the amount of medicine injected according to the different diameters of pine trees to save on pesticides. Summary of the Invention

[0004] The purpose of this invention is to provide an injection device for the control of pine nematode disease, which allows for direct injection of pesticides into pine trees after drilling, significantly improving injection efficiency. Furthermore, it enables precise control of drilling depth and injection volume based on the diameter of pine trees, thereby enhancing the control effect of pine nematode disease.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a drug injection device for the prevention and control of pine nematode disease, comprising a supply box, a drill, a measuring rod, and a drill rod. A wire is connected to the drill, and the other end of the wire is connected to the supply box. The supply box contains a battery and stores the drug. A base is fixedly connected to the bottom of the drill. An installation box is fixedly connected to the upper end of the base away from the drill. The installation box contains a drive mechanism and a drug supply mechanism. A sliding groove is provided on the side wall of the installation box away from the drill. Two measuring rods are provided. One measuring rod is fixedly connected to the installation box, and a slider is fixedly connected to the other measuring rod. The slider is slidably connected to the sliding groove. An indicator rod is slidably sleeved on the drill rod.

[0006] The drive mechanism includes a second rotating shaft and a second rack. A round rod is fixedly connected inside the mounting box, and a rack is slidably connected to the outside of the round rod. The second rotating shaft is rotatably connected inside the mounting box. A second gear and a first bevel gear are coaxially fixedly connected to the outside of the second rotating shaft. The second gear meshes with the second rack, and the second rack is fixedly connected to the slider.

[0007] The drive mechanism also includes rack one, shaft one, and gear one. Shaft one is rotatably connected inside the mounting box. Gear one and bevel gear two are coaxially connected to the outside of shaft one. Bevel gear two meshes with bevel gear one. A limit rod is also fixed inside the mounting box. One end of the limit rod is slidably inserted into rack one. Limit blocks are provided on both sides of rack one. Limit grooves are also provided on the mounting box. Rack one is slidably connected inside the limit groove. Rack one meshes with gear one. The upper end of rack one is fixedly connected to the bottom end of the indicator rod.

[0008] Guide rods are fixed to the ends of the two measuring rods away from the mounting box. A sleeve is fixed to the measuring rod fixed to the mounting box, and a sleeve rod is fixed to the measuring rod slidably connected to the mounting box. One end of the sleeve rod is slidably connected to the sleeve, and a spring is fixed between the sleeve rod and the sleeve.

[0009] The drug supply mechanism includes a transition tube, a clamp tube, a conical head, and a drug supply box. The drug supply box is fixed inside the mounting box. A drug supply tube is connected to the drug supply box. A pipe clamp is fixed to the base. The end of the drug supply tube away from the drug supply box passes through the pipe clamp and is tied together with the wire and connected to the inside of the supply box. A push rod is also fixed to the upper end of rack one. Push plate one and push plate two are slidably connected inside the drug supply box. Spring three is fixed between push plate one and push plate two. The push rod is fixed to push plate one.

[0010] The upper end of the medicine supply box is fixedly connected to a support column and a medicine outlet pipe. The upper end of the support column is fixedly connected to a transition pipe, which is connected to the medicine outlet pipe. The output end of the drilling rig is fixedly connected to a chuck. The chuck is equipped with a limiting ring one, and the end of the chuck is fixedly connected to a plug rod three. The limiting ring one is rotatably connected inside the transition pipe. A clamping pipe is provided between the drill rod and the transition pipe.

[0011] The clamp tube is provided with a second insertion hole and a second limiting ring. The second limiting ring is rotatably connected inside the transition tube. The third insertion rod is inserted into the second insertion hole. The clamp tube is fixedly connected to a fixed ring and slidably connected to a sliding ring. A second spring is fixedly connected between the sliding ring and the fixed ring. A stop block is provided on one side of the sliding ring. A first spring is fixedly connected between the stop block and the clamp tube. A first insertion rod is fixedly connected to the end of the stop block near the clamp tube. The first insertion rod slides into the inside of the clamp tube.

[0012] The drill pipe has a hole inside, and the transition pipe, clamp pipe and the hole are connected. The clamp pipe has a first insertion hole inside. One end of the conical head is fixedly connected to the second insertion rod. The end of the second insertion rod away from the conical head slides through the drill pipe and slides into the first insertion hole. The first insertion rod and the second insertion rod slide into each other. The drill pipe and the clamp pipe are threaded together.

[0013] The beneficial effects of this invention are:

[0014] 1. By setting up the measuring rod and driving mechanism, when drilling holes in pine trees of different diameters, the measuring rod can be used to abut against the outer wall of the pine tree to measure the diameter of the pine tree. At the same time, driven by the rack one, rack two, gear one and other structures, the indicator rod moves on the drill rod to obtain the drilling depth. This enables precise control of the drilling depth when injecting pesticides into pine trees of different diameters, ensuring that the pesticide can penetrate a certain distance into the wood of the pine tree, so that the pesticide can spread throughout the pine tree and ensure the control effect of pine nematode disease.

[0015] 2. By setting up the drug supply mechanism, when the measuring rod touches the outer wall of the pine tree to measure the diameter of the pine tree, the movement of the measuring rod can also drive the movement of the push rod. The greater the distance the measuring rod moves, the greater the distance the push rod moves. When the push rod pushes the first and second push plates, the drug inside the drug supply box is injected into the tree hole through the transition tube, the clamping tube, and the tube hole. This achieves precise control of the amount of drug injected when injecting drugs into pine trees of different diameters, which saves drugs while ensuring the control effect of pine nematode disease.

[0016] 3. The tapered head allows it to rotate with the drill rod during drilling, facilitating hole drilling and sealing the borehole to prevent blockage and ensure the flow of chemicals. During injection, the tapered head separates from the drill rod, allowing the chemicals to flow directly from the borehole for injection. This eliminates the need for a separate injection device after drilling, simplifying the injection process and significantly improving work efficiency. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figures 1-10The device shown is an injection device for controlling pine nematode disease, comprising a supply box 1, a drill 3, a measuring rod 7, and a drill rod 5. A wire 2 is connected to the drill 3, with the other end of the wire 2 connected to the supply box 1. The supply box 1 contains a battery and stores the pesticide. A base 9 is fixedly connected to the bottom of the drill 3. An installation box 8 is fixedly connected to the upper end of the base 9 away from the drill 3. The installation box 8 contains a drive mechanism and a pesticide supply mechanism. A groove 12 is provided on the side wall of the installation box 8 away from the drill 3. Two measuring rods 7 are provided; one measuring rod 7 is fixedly connected to the installation box 8, and a slider 11 is fixedly connected to the other measuring rod 7. The slider 11 is slidably connected to the groove 12. An indicator rod 13 is slidably fitted onto the drill rod 5. Because pine trees have different diameters, generally, pine trees with larger diameters are older, and their phloem and xylem... The thicker the wood, the more the pine tree's xylem has a transport system that can deliver the injected pesticide throughout the tree. Therefore, the drilling depth needs to penetrate 5-7 cm into the xylem. When drilling in the field, workers cannot accurately determine the diameter of the pine tree and obtain the precise drilling depth based on the diameter. This leads to poor control of nematode disease after pesticide injection. The measuring rod 7 in this application can measure the diameter of the pine tree, and the movement of the measuring rod 7 when measuring the diameter of the pine tree can drive the indicator rod 13 to slide on the drill rod 5 to accurately indicate the drilling depth of the drill rod 5 corresponding to the measured diameter of the pine tree. This allows for precise control of the drilling depth according to trees of different diameters, ensuring that the pesticide injection penetrates 5-7 cm into the xylem and guaranteeing the pesticide's control effect on nematode disease.

[0030] The driving mechanism includes a second rotating shaft 31 and a second rack 25. A round rod 26 is fixedly connected inside the mounting box 8, and a rack 25 is slidably connected to the outside of the round rod 26. The second rotating shaft 31 is rotatably connected inside the mounting box 8. A second gear 30 and a first bevel gear 32 are coaxially fixedly connected to the outside of the second rotating shaft 31. The second gear 30 meshes with the second rack 25, and the slider 11 is fixedly connected to the rack 25.

[0031] The drive mechanism also includes a rack 19, a rotating shaft 29, and a gear 24. The rotating shaft 29 is rotatably connected inside the mounting box 8. Gear 24 and bevel gear 33 are coaxially connected to the outside of the rotating shaft 29. The bevel gear 33 meshes with bevel gear 32. A limit rod 27 is also fixed inside the mounting box 8. One end of the limit rod 27 is slidably inserted into the rack 19. Limit blocks 28 are provided on both side walls of the rack 19. The mounting box 8 is also provided with a limit groove 23. Rack 19 is slidably connected inside the limiting groove 23. Rack 19 is meshed with gear 24. The upper end of rack 19 is fixedly connected to the bottom end of indicator rod 13. The meshing connection between gear 20 and rack 25, and between rack 19 and gear 24, can ensure a high-precision transmission ratio, so that the measuring rod 7 can be accurately transmitted to the indicator rod 13 when it moves. This achieves the improvement of the indicating length of indicator rod 13 and the accuracy of drilling depth by using the precise fit of the mechanical structure.

[0032] Guide rods 6 are fixedly connected to the ends of the two measuring rods 7 away from the mounting box 8. The guide rods 6 are designed to facilitate inserting the pine tree between the two measuring rods 7. A sleeve 18 is fixedly connected to the measuring rod 7 fixed to the mounting box 8. A sleeve rod 10 is fixedly connected to the measuring rod 7 slidably connected to the mounting box 8. One end of the sleeve rod 10 is slidably connected to the sleeve 18, and a spring four is fixedly connected between the sleeve rod 10 and the sleeve 18. After the subsequent drilling and injection are completed, the sleeve rod 10 retracts into the sleeve 18 under the action of the spring four, and the two measuring rods 7 can be reset.

[0033] The drug supply mechanism includes a transition tube 16, a clamp tube 22, a conical head 14, and a drug supply box 50. The drug supply box 50 is fixed inside the mounting box 8. A drug supply tube 4 is connected to the drug supply box 50. A tube clamp 49 is fixed to the base 9. The end of the drug supply tube 4 away from the drug supply box 50 passes through the tube clamp 49 and is tied together with the wire 2 and connected to the inside of the supply box 1. A push rod 20 is also fixed to the upper end of the rack 19. A push plate 21 and a push plate 40 are slidably connected inside the drug supply box 50. A spring 41 is fixed between the push plate 21 and the push plate 40. The push rod 20 is fixed to the push plate 21. When the measuring rod 7 is reset, the push rod 20 can be driven to move closer to the measuring rod 7 by the drive mechanism. This causes the push rod to drive the push plate 21 and the push plate 40 to slide inside the drug supply box 50. The drug is drawn into the drug supply box 50 through the drug supply tube 4 for the next injection.

[0034] The upper end of the medicine supply box 50 is fixedly connected to a support column 15 and a medicine outlet pipe 51. The upper end of the support column 15 is fixedly connected to a transition pipe 16, which is connected to the medicine outlet pipe 51. The output end of the drilling rig 3 is fixedly connected to a chuck 17. The chuck 17 is provided with a limiting ring 42, and the end of the chuck 17 is fixedly connected to a insertion rod 46. The limiting ring 42 is rotatably connected inside the transition pipe 16. A clamping tube 22 is provided between the drill rod 5 and the transition pipe 16.

[0035] The clamping tube 22 is provided with a second insertion hole 48 and a second limiting ring 45. The second limiting ring 45 is rotatably connected inside the transition tube 16. The third insertion rod 46 is inserted into the second insertion hole 48. The clamping tube 22 is fixedly connected to a fixed ring 39 and slidably connected to a sliding ring 37. A second spring 38 is fixedly connected between the sliding ring 37 and the fixed ring 39. A stop block 34 is provided on one side of the sliding ring 37. A first spring 36 is fixedly connected between the stop block 34 and the clamping tube 22. A first insertion rod 35 is fixedly connected to one end of the stop block 34 near the clamping tube 22. The first insertion rod 35 slides into the inside of the clamping tube 22. The transition tube 16 can both allow the clamping head 17 to drive the clamping tube 22 to rotate and allow the agent to be injected into the tube hole 43 through the transition tube 16 and the clamping tube 22 when the clamping tube 22 rotates. Subsequently, the agent can be injected directly into the tree hole using the drill rod 5, improving work efficiency.

[0036] The drill rod 5 has a pipe hole 43 inside, and the transition pipe 16, the clamping pipe 22 and the pipe hole 43 are connected. The clamping pipe 22 has an insertion hole 47 inside. One end of the conical head 14 is fixedly connected to the insertion rod 44. The end of the insertion rod 44 away from the conical head 14 slides through the drill rod 5 and slides into the insertion hole 47. The insertion rod 35 slides into the insertion rod 44. The drill rod 5 is threadedly connected to the clamping pipe 22.

[0037] Working principle of the invention:

[0038] When in use, staff can carry supply box 1 on their backs. Figure 1The lengths of the guide wire 2 and the drug supply tube 4 do not represent the actual lengths; they are only shown in the attached diagram for a simpler illustration. First, tighten the drill rod 5 and the clamp tube 22 with threads. Then, move the slip ring 37 so that it presses against the stop block 34. The stop block 34 will then cause the insertion rod 35 to extend out of the clamp tube 22. Next, slide the insertion rod 44 of the conical head 14 into the drill rod 5, making the insertion rod 44 slide into the insertion hole 47. Then, loosen the slip ring 37, and the slip ring 37 will disengage from the stop block 34. The stop block 34 will then be held in place by the spring 36. Under the action of resetting, the insertion rod 35 is inserted into the insertion rod 44 to limit the conical head 14. The conical head 14 is tightly fitted with the end of the drill rod 5, sealing the tube hole 43. This allows the conical head 14 to rotate with the drill rod 5, facilitating drilling. At the same time, it can prevent debris from entering the tube hole 43 during drilling, causing blockage inside the tube hole 43 and affecting the flow of the medicine. When it is necessary to inject medicine, the conical head 14 can be separated from the end of the drill rod 5 by one end, allowing the medicine to enter the xylem of the pine tree.

[0039] Then, when drilling is required into the pine tree, and the hole depth reaches 5-7cm into the wood, the worker can hold the drill rig 3 so that the guide rod 6 abuts against the outer wall of the pine tree until the two measuring rods 7 abut against the outer wall of the pine tree. During the process of abutting against the outer wall of the pine tree, the measuring rod 7 fixed to the mounting box 8 remains stationary, while the measuring rod 7 slidably connected to the mounting box 8 will slide along the sliding groove 12. This measuring rod 7 moves away from the fixed measuring rod 7 until the two measuring rods 7 abut against the outer wall of the pine tree. When the sliding measuring rod 7 moves, it will drive the rack 25 to move along the round rod 26 through the slider 11. When the rack 25 moves, it drives the gear 20 to rotate. When the gear 20 rotates, it drives the coaxial bevel gear 32 to rotate. The bevel gear 32 drives the bevel gear 33 to rotate. The bevel gear 33 drives the coaxial gear 24 to rotate. The gear 24 then drives the rack 19 to move along the limiting groove 23 and the limiting rod 27. When the rack 19 moves, it moves the indicator rod 13 fixed to it. The indicator rod 13 then slides on the drill rod 5. The larger the diameter of the pine tree, the greater the distance the measuring rod 7 moves. The greater the distance the rack 19 moves the indicator rod 13, the greater the drilling depth of the drill rod 5. The length of the drill rod 5 between the indicator rod 13 and the conical head 14 can reach a hole depth of 5-7 cm into the pine wood. This allows for accurate control of the drilling depth according to the diameter of different pine trees. It avoids the situation where the hole depth is too small, causing the pesticide to only stay in the phloem and other parts and not be able to enter the transport system of the pine wood, resulting in the pesticide being completely ineffective and reducing the control effect of pine nematode disease. When the hole depth is too large, the pesticide will enter the heartwood of the pine tree. After entering the heartwood, the pesticide is difficult to be transported to the crown and most of it will remain near the hole, which will also reduce the control effect of pine nematode disease.

[0040] Next, the drill rig 3 is started. The chuck 17 of the drill rig 3 drives the chuck tube 22 to rotate through the insertion rod 3 46. The chuck tube 22 drives the drill rod 5, which is threaded to it, to rotate. The drill rod 5 drives the conical head 14 to rotate through the insertion rod 2 44, thereby drilling a hole in the pine tree. At the same time, when the rack 1 19 moves, it also drives the push rod 20 to move. The larger the diameter of the pine tree, the greater the distance that the rack 1 19 drives the push rod 20 to move. The push rod 20 will drive the push rod 21 to squeeze the spring 3 41. The spring 3 41 is in a compressed state to store energy. Since the conical head 14 is in contact with the drill rod 5 at this time, it blocks the pipe hole 43 on the drill rod 5. Therefore, the push plate 2 40 remains stationary under the elastic compression of the spring 3 41.

[0041] After drilling, the drill rod 5 can extend a short distance out of the tree hole. Then, the slip ring 37 is moved, causing it to press against the block 34. The block 34 then drives the insertion rod 35 to extend out of the clamping tube 22, releasing the conical head 14 from its limit. The energy-storing spring 3 41 can then drive the push plate 2 40 to squeeze the medicine inside the medicine supply box 50. The medicine enters the transition tube 16, clamping tube 22, and the tube hole 43 of the drill rod 5 through the medicine outlet tube 51. The medicine inside the tube hole 43 impacts the conical head 14, which is no longer limited and can slide on the drill rod 5 via the insertion rod 2 44. The conical head 14 separates from the drill rod 5 by a certain distance, and the medicine flows into the pine tree hole. This allows for the injection of different amounts of medicine according to the diameter of the pine tree, saving medicine while ensuring the control effect of pine nematode disease. Furthermore, it does not require electricity to power the injection of medicine, allowing all electrical energy to be used for drilling pine trees, enabling the injection of medicine into more pine trees at once.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
