Description

Technical Field

[0001] The invention relates to the technical field of pest control, and more specifically to a device for controlling pine wood nematode disease. Background Art

[0002] The pine wood nematode is a pest that can cause the death of pine trees. It has no ability to spread itself and is mainly spread by vector insects, such as the pine beetle (also known as the pine alternator). The pine wood nematode enters the pine tree through the wounds caused by the pine beetle when it supplements nutrition. Once a pine tree is infected with pine nematode disease, it will die quickly. Therefore, pine nematode disease is highly harmful to pine wood. Since the pine wood nematode relies on the pine beetle for transmission, reducing the number of beetles can significantly reduce the transmission efficiency of the nematode. Killing the beetle larvae can effectively cut off the transmission route of the pine wood nematode. Therefore, existing pine nematode control devices usually focus on killing the beetle larvae.

[0003] In the existing technology, when preventing and controlling pine nematode disease, it is usually carried out by injecting pesticides into pine trees or spraying pesticides through drones. However, injecting pesticides will cause certain damage to pine wood. The larvae of longhorn beetles mainly live in the middle and lower sections of pine trunks.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] Reference Figure 1-13A device for preventing and controlling pine wood nematode disease comprises a first guide frame 1, one side of the first guide frame 1 is rotatably connected to a second guide frame 2 via a rotating shaft, one side of the bottom of the first guide frame 1 is fixedly connected to a water tank 3, an interior of the water tank 3 is provided with insecticide, one side of the first guide frame 1 and the second guide frame 2 is provided with a guide groove, an inner wall of the guide groove is slidably connected to a connecting rod, one end of the connecting rod is fixedly connected to a first motor 4, the other end of the connecting rod is fixedly connected to a first gear 5, the inner walls of the first guide frame 1 and the second guide frame 2 are both fixedly connected to a first rack 7, the first gear 5 is meshed on one side of the first rack 7, both sides of the connecting rod are rotatably connected to blocks 6, the blocks 6 is slidably connected to the inner wall of the first guide frame 1 and the second guide frame 2, and also includes an adjustment component for adjusting the spraying angle, the adjustment component is arranged on one side of the block 6, the adjustment component includes a nozzle 12, the nozzle 12 is arranged on one side of the block 6, a transmission component for conveying insecticide is arranged at the top of the water tank 3, the transmission component includes a transmission pipe 20, the transmission pipe 20 is fixedly connected to the top of the water tank 3, a storage component for accommodating the transmission pipe 20 is arranged at the top of the water tank 3, a stirring component for stirring the disinfectant is arranged inside the water tank 3, and a fixing component for fixing the first guide frame 1 and the second guide frame 2 is arranged on one side of the first guide frame 1.

[0033] In order to solve the problem that it is inconvenient to spray medicine on the tree trunks where longhorn beetles live, when it is necessary to spray the pine trees, the second guide frame 2 can be flipped upward. After the second guide frame 2 is flipped, it will be aligned with the top of the first guide frame 1. By setting a fixing component, the positions of the first guide frame 1 and the second guide frame 2 can be fixed. By setting a transmission component, the pesticide in the water tank 3 can be transferred to the nozzle 12, so that the pesticide is sprayed out from the nozzle 12. Then the first motor 4 can be started. When the first motor 4 is started, it will drive the connecting rod and the first gear 5 on one side to rotate, and when the first gear 5 rotates, it will move on the first rack 7, and at the same time The block 6 is driven to slide on the inner wall of the first guide frame 1 and the second guide frame 2. When the block 6 slides, it will drive the nozzle 12 to move together. At the same time, the nozzle 12 will cooperate with the adjustment component to operate. Through the adjustment component, when encountering branches, the position can be adjusted to pass through the branches. At the same time, the direction of the nozzle 12 can also be changed when the adjustment component is running, so as to evenly spray the outer wall of the trunk of the pine tree. By setting up a storage component, the transmission tube 20 can be stored when the block 6 moves downward to prevent the transmission tube 20 from falling at will. By setting up a stirring component, the stirring component can be driven to evenly stir the insecticide in the water tank 3 when the block 6 moves up and down.

[0034] Reference Figure 5-6The adjustment component also includes a rotating structure, which includes an arc frame 8, which is fixedly connected to one side of the block 6, and the inner wall of the arc frame 8 is slidably connected to an arc block 11. The nozzles 12 are provided in multiple groups and are distributed in an arc shape on the inner wall of the arc block 11. The nozzles 12 are rotatably connected to the arc block 11. A second motor 9 is fixedly connected to the top of the arc frame 8, and a second gear 10 is fixedly connected to the output end of the second motor 9. A second rack is fixedly connected to the outer wall of the arc block 11, and the second gear 10 is meshed on one side of the second rack. Two groups of baffles are fixedly connected to both ends of the arc block 11.

[0035] The insecticide in the water tank 3 will be injected into the arc block 11 through the transmission pipe 20 and sprayed toward the tree trunk through the nozzle 12. When it is necessary to avoid branches, the second motor 9 can be started to drive the second gear 10 to rotate. When the second gear 10 rotates, since the second rack provided on the outer wall of the arc block 11 is meshed with the second gear 10, the second gear 10 will drive the arc block 11 to rotate in the arc frame 8 when rotating, thereby changing the angle of the arc block 11, so that the notch of the arc block 11 moves to the bottom of the branch, so that the arc block 11 can pass through the branch of the pine tree through the notch of the arc block 11, so that the arc block 11 can move upward along the trunk. By arranging two sets of baffles at both ends of the arc block 11, the arc block 11 can be prevented from falling off from the arc frame 8. When the arc block 11 rotates, the direction of spraying the trunk can also be changed, which is conducive to uniform spraying of the trunk.

[0036] Reference Figure 3-4 The adjustment assembly also includes a direction adjustment structure, which includes a bevel gear 13, which is fixed to the outer wall of the nozzle 12, one end of the nozzle 12 is inclined to one side, the top of the water tank 3 is fixed with a pump, and the pump is arranged on one side of the transmission pipe 20, the bottom of the inner wall of the arc frame 8 is fixed with an arc-shaped bevel gear ring 14, the shape of the arc-shaped bevel gear ring 14 is arc-shaped, the bevel gear 13 is meshed with the top of the arc-shaped bevel gear ring 14, and the top of the arc block 11 is provided with an arc groove Two groups of sealed pads 15 are fixedly connected to the two sides of the inner wall of the arc groove, a connecting pipe 19 is fixedly connected to the center of the arc frame 8, a slip ring 16 is fixedly connected to the bottom of the connecting pipe 19, a circular groove is opened on the outer wall of the slip ring 16, the two groups of sealed pads 15 are attached to the inner wall of the circular groove, an entry pipe 17 is fixedly connected to the bottom of the slip ring 16, the entry pipe 17 extends into the inner wall of the arc block 11, a cover plate 18 is fixedly connected to the outer wall of the connecting pipe 19, and the transmission pipe 20 is fixedly connected to the top of the connecting pipe 19.

[0037] When the nozzle 12 moves with the arc block 11, the bevel gear 13 arranged on the outer wall thereof will be driven to move together. Since the bevel gear 13 is meshed with the top end of the arc bevel gear ring 14, the bevel gear 13 will drive the bevel gear 13 and the nozzle 12 to rotate through the arc bevel gear ring 14 when the nozzle 12 moves. Since one end of the nozzle 12 is inclined to one side, the spraying angle will be changed when the nozzle 12 rotates, so that the pesticide can be sprayed evenly on the surface of the tree trunk. By setting a pump, the pesticide in the water tank 3 can be pumped into the transmission pipe 20 and passed through the transmission pipe 20. The insecticide is transferred to the connecting tube 19 and the inlet tube 17, and is injected into the inner wall of the arc block 11 through the inlet tube 17. When the arc block 11 slides, the two groups of sealed pads 15 arranged in the top arc groove will be driven to slide together. Since a slip ring 16 is arranged at the top of the inlet tube 17, and a circular groove is arranged on the outer wall of the slip ring 16, when the two groups of sealed pads 15 pass through the slip ring 16, the circular groove on the outer wall of the slip ring 16 will separate the two groups of sealed pads 15. When the slip ring 16 moves to the other side, the two groups of sealed pads 15 will close again, thereby keeping most of the top area of ​​the arc groove sealed.

[0038] Reference Figure 7 and Fig.10 The transmission component includes a support plate 23, which is fixed to the top of the water tank 3. One side of the support plate 23 is rotatably connected to a mounting tube 24. The outer wall of the mounting tube 24 is provided with a threaded groove 25. The transmission tube 20 is wound around the inner wall of the threaded groove 25. The top of the arc frame 8 is slidably connected to a first pulley 21. One side of the arc frame 8 is rotatably connected to a second pulley 22. The transmission tube 20 is slidably connected to the tops of the first pulley 21 and the second pulley 22.

[0039] When the transmission tube 20 is pulled upward, the installation cylinder 24 is driven to rotate through the storage assembly, and the transmission tube 20 wrapped around the outer wall of the installation cylinder 24 is gradually released along the thread groove 25. By setting the first pulley 21 and the second pulley 22, the transmission tube 20 can be protected by the first pulley 21 and the second pulley 22 when the arc block 11 and the arc frame 8 move upward, thereby reducing the friction between the transmission tube 20 and the arc frame 8. By setting the thread groove 25, when the transmission tube 20 is stored, it is convenient to spirally store the transmission tube 20 along the thread groove 25, thereby preventing the transmission tube 20 from being disorderly wound around the outer wall of the installation cylinder 24, and facilitating the storage and release of the transmission tube 20.

[0040] Reference Figure 8-9The storage assembly includes a column 26, which is fixed to the top of the water tank 3. A frame plate 27 is fixed to the top of the column 26. A first spring 28 is fixed to the inner wall of the frame plate 27. A pressure plate 29 is fixed to the bottom of the first spring 28. A circular groove is provided at the bottom of the pressure plate 29. A fourth gear 30 is fixed to one side of the mounting tube 24. A transverse plate 31 is fixed to one side of the arc frame 8. A toothed belt 32 is fixed to the bottom of the transverse plate 31. The toothed belt 32 is meshed with the bottom of the fourth gear 30. A limiting ring 33 is fixed to the top of the water tank 3. A support block 34 is fixedly connected to one side of the water tank 3, and a storage tube 35 is fixedly connected to the top of the support block 34. The storage tube 35 is circular in shape, and the end of the toothed belt 32 away from the horizontal plate 31 extends into the interior of the storage tube 35. A fixing rod 37 is fixedly connected to the center of the inner wall of the storage tube 35, and a coil spring 38 is fixedly connected to the outer wall of the fixing rod 37. The end of the coil spring 38 away from the fixing rod 37 is fixed to one side of the toothed belt 32. A third pulley 36 is rotatably connected to one side of the storage tube 35, and one side of the toothed belt 32 is slidably connected to the top of the third pulley 36.

[0041] When the arc frame 8 moves upward, it will drive the horizontal plate 31 on one side to move upward, and when the horizontal plate 31 moves upward, it will pull the top of the toothed belt 32 to move upward together. When the toothed belt 32 is pulled, it will drive the fourth gear 30 to rotate, and when the fourth gear 30 rotates, it will drive the installation cylinder 24 to rotate, so that the transmission tube 20 in the threaded groove 25 on the outer wall of the installation cylinder 24 is gradually released. When the toothed belt 32 is pulled, the coil spring 38 arranged in the receiving cylinder 35 will be gradually tightened, so that the coil spring 38 is tightened toward the center. By setting the third pulley 36, the sliding position of the toothed belt 32 can be limited. By setting the limiting ring 33, the meshing state between the toothed belt 32 and the fourth gear 30 can be maintained. When the arc frame 8 and the cross plate 31 move downward, the top end of the toothed belt 32 will move downward, and at the same time, the toothed belt 32 will be rolled into the storage tube 35 through the reset potential energy of the coil spring 38. When the toothed belt 32 is rolled into the storage tube 35, it will drive the fourth gear 30 and the mounting tube 24 to rotate in the opposite direction, so that the transmission tube 20 is stored in the threaded groove 25 on the mounting tube 24. When the transmission tube 20 is stored, the first spring 28 can provide a downward thrust for the pressure plate 29, which can cause the transmission tube 20 to be pressed on the threaded groove 25 by the pressure plate 29 during storage, thereby keeping the transmission tube 20 wound on the threaded groove 25 during storage, and the circular groove set at the bottom of the pressure plate 29 can cooperate with the transmission tube 20 for storage.

[0042] Reference Fig.11The stirring assembly includes a first pulley 39, which is fixedly connected to one end of the mounting tube 24 away from the fourth gear 30. A transmission belt 40 is sleeved on the outer wall of the first pulley 39, and a second pulley 41 is sleeved on the bottom of the inner wall of the transmission belt 40. A round rod 42 is fixedly connected to one side of the second pulley 41, and one end of the round rod 42 is rotatably connected to the inner wall of the water tank 3. A stirring blade 43 is fixedly connected to the outer wall of the round rod 42, and the stirring blade 43 is arranged inside the water tank 3.

[0043] When the mounting cylinder 24 rotates, the first pulley 39 on one side will be driven to rotate, and when the first pulley 39 rotates, the transmission belt 40 arranged on its outer wall will be driven to rotate, and when the transmission belt 40 rotates, the second pulley 41 arranged at the bottom will be driven to rotate, and when the second pulley 41 rotates, the round rod 42 and the stirring blade 43 on one side will be driven to rotate at the same time, and when the stirring blade 43 rotates, the insecticide in the water tank 3 will be stirred, so that the insecticide can be fully mixed evenly.

[0044] Reference Fig.13 The fixing assembly includes an insert strip 44, which is fixedly connected to the bottom of the second guide frame 2. A fixing seat 45 is fixedly connected to the top of the first guide frame 1. A groove is provided on one side of the inner wall of the fixing seat 45. A pull rod 47 is slidably connected to the inner wall of the groove. A fixing block 48 is fixedly connected to one side of the pull rod 47. The fixing block 48 is arranged at the top of one side of the insert strip 44. A second spring 46 is fixedly connected to the outer wall of the pull rod 47. The other end of the second spring 46 is fixedly connected to the inner wall of the groove.

[0045] When the second guide frame 2 is flipped to the top of the first guide frame 1, the insertion strip 44 provided on one side of the second guide frame 2 will be flipped accordingly and inserted into the inside of the fixing seat 45, so that the bottom of the insertion strip 44 is inserted into the bottom of the fixing block 48, and the second spring 46 can keep the pull rod 47 and the fixing block 48 in the original position, so that the position of the first guide frame 1 and the second guide frame 2 can be fixed by fixing the position of the insertion strip 44, and when it is necessary to move the second guide frame 2 away from the top of the first guide frame 1, the pull rod 47 can be pulled, and when the pull rod 47 is pulled, the fixing block 48 can be driven to move to one side, so that the fixing block 48 is retracted into the inside of the groove and the second spring 46 is squeezed, and when the fixing block 48 is moved away from one side of the insertion strip 44, the fixation of the insertion strip 44 can be released, so that the second guide frame 2 can be removed from the first guide frame 1.

[0046] Working principle: In order to solve the problem that it is inconvenient to spray medicine on the trunks where longhorn beetles live, when it is necessary to spray the pine trees, the second guide frame 2 can be flipped upwards. After the second guide frame 2 is flipped, it will be aligned with the top of the first guide frame 1. When the second guide frame 2 is flipped to the top of the first guide frame 1, the cutting strip 44 set on one side of the second guide frame 2 will be flipped and inserted into the inside of the fixing seat 45, so that the bottom of the cutting strip 44 is inserted into the bottom of the fixing block 48, and the second spring 46 can keep the pull rod 47 and the fixing block 48 in the original position, so that the position of the first guide frame 1 and the second guide frame 2 can be fixed by fixing the position of the cutting strip 44;

[0047] By setting a pump, the insecticide in the water tank 3 can be pumped into the transmission pipe 20, and the insecticide is transferred to the connecting pipe 19 and the inlet pipe 17 through the outlet transmission pipe 20, and injected into the inner wall of the arc block 11 through the inlet pipe 17, and sprayed toward the tree trunk through the nozzle 12. When it is necessary to avoid branches, the second motor 9 can be started, and the second gear 10 can be driven to rotate by the second motor 9. When the second gear 10 rotates, the second rack arranged on the outer wall of the arc block 11 meshes with the second gear 10. Therefore, when the second gear 10 rotates, it will drive the arc block 11 to rotate in the arc frame 8, so that the angle of the arc block 11 can be changed, so that the notch of the arc block 11 moves to the bottom of the branch, so that the arc block 11 can pass through the branch of the pine tree through the notch of the arc block 11, so that the arc block 11 can move upward along the trunk. By setting two sets of blocking pieces at both ends of the arc block 11, the arc block 11 can be prevented from falling off from the arc frame 8. When the arc block 11 slides, it will drive the two sets of blocking pieces set in the top arc groove to move upward along the trunk. The two groups of sealed pads 15 slide together. Since a slip ring 16 is provided at the top of the entry tube 17, and a circular groove is provided on the outer wall of the slip ring 16, when the two groups of sealed pads 15 pass through the slip ring 16, the circular groove on the outer wall of the slip ring 16 will separate the two groups of sealed pads 15. When the slip ring 16 moves to the other side, the two groups of sealed pads 15 will close again, thereby keeping most of the area at the top of the arc groove sealed. When the arc block 11 rotates, the direction of spraying the tree trunk can also be changed, which is beneficial to spraying the tree trunk. When the nozzle 12 moves with the arc block 11, the bevel gear 13 arranged on the outer wall thereof will be driven to move together. Since the bevel gear 13 is meshed with the top end of the arc bevel gear ring 14, the bevel gear 13 will drive the bevel gear 13 and the nozzle 12 to rotate through the arc bevel gear ring 14 when the nozzle 12 moves. Since one end of the nozzle 12 is inclined to one side, the spraying angle will be changed when the nozzle 12 rotates, so that the insecticide can be sprayed evenly on the surface of the tree trunk more easily.

[0048] When the arc frame 8 moves upward, it will drive the horizontal plate 31 on one side to move upward, and when the horizontal plate 31 moves upward, it will pull the top of the toothed belt 32 to move upward together. When the toothed belt 32 is pulled, it will drive the fourth gear 30 to rotate, and when the fourth gear 30 rotates, it will drive the installation cylinder 24 to rotate, so that the transmission tube 20 in the threaded groove 25 on the outer wall of the installation cylinder 24 is gradually released. When the toothed belt 32 is pulled, the coil spring 38 set in the storage cylinder 35 will be gradually tightened, so that the coil spring 38 is tightened toward the center, and the third pulley 3 is set. 6, the sliding position of the toothed belt 32 can be limited, and the meshing state between the toothed belt 32 and the fourth gear 30 can be maintained by setting the limiting ring 33. By setting the first pulley 21 and the second pulley 22, when the arc block 11 and the arc frame 8 move upward, the first pulley 21 and the second pulley 22 can be used to protect the transmission tube 20, thereby reducing the friction between the transmission tube 20 and the arc frame 8. When the arc frame 8 and the cross plate 31 move downward, the top of the toothed belt 32 moves downward, and the toothed belt 32 is retracted by the reset potential energy of the coil spring 38. The toothed belt 32 is wound into the receiving cylinder 35, and when the toothed belt 32 is wound into the receiving cylinder 35, it will drive the fourth gear 30 and the mounting cylinder 24 to rotate in the opposite direction, so that the transmission tube 20 is received in the thread groove 25 on the mounting cylinder 24. When the transmission tube 20 is received, the first spring 28 can provide a downward thrust for the pressing plate 29, which can cause the transmission tube 20 to be pressed on the thread groove 25 by the pressing plate 29 when it is received, so as to keep the transmission tube 20 wound on the thread groove 25 when it is received, and the circular groove provided at the bottom of the pressing plate 29 can cooperate with the transmission tube 20 for receiving. To prevent the transmission tube 20 from being disorderly wound around the outer wall of the installation cylinder 24, when the installation cylinder 24 rotates, it will drive the first pulley 39 on one side to rotate, and when the first pulley 39 rotates, it will drive the transmission belt 40 set on its outer wall to rotate, and when the transmission belt 40 rotates, it will drive the second pulley 41 set at the bottom to rotate, and when the second pulley 41 rotates, it will drive the round rod 42 and the stirring blade 43 on one side to rotate at the same time, and when the stirring blade 43 rotates, it will stir the pesticide in the water tank 3, which can promote the full and uniform mixing of the pesticide.
