Description

Technical Field

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

[0002] Pine wilt disease, also known as pine wood nematode disease, is a destructive disease caused by the pine wood nematode. The main characteristic of pine nematode disease is the rapid wilting and death of pine trees. Infected pine trees exhibit symptoms such as gradually yellowing and withering of the crown, softening of the trunk, and ultimately, tree death. This is due to the pine nematode parasitizing and multiplying inside the pine tree, leading to its decline and death. A pine wilt disease control agent injection device is a device used to control pine wilt disease. It is used to inject pesticides into infected pine wood to control and prevent the spread and reproduction of the pine wood nematode.

[0003] However, existing pine wilt nematode control agents cannot quickly apply the ring to the surface of the tree, thus lengthening the control cycle and reducing the efficiency of pine wilt nematode control. This may lead to the death of some trees due to untimely control.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] To solve the above problems, the technical solution of this utility model is: a pine wilt nematode control agent injection device, including a quick-release structure, which solves the problem that the existing pine wilt nematode control agent injection device cannot quickly put the ring on the surface of the tree, thus making the pine wilt nematode control cycle longer and the efficiency of pine wilt nematode control reduced, which may lead to the death of some trees due to untimely control. Preferably, the collar has two symmetrically arranged fixing plates fixedly connected to one end, and the surface of the collar is provided with a sliding structure, which includes an injection mechanism and a swing mechanism. The hinge plates are arranged in three sets on the inner side of the collar, with two hinge plates in each set. A flat plate is fixedly connected to one end of each hinge plate that is close to the other. A quick-release structure is provided at one end of a fixed plate, and the quick-release structure includes a disassembly mechanism and a fixing mechanism.

[0006] Furthermore, the swing mechanism includes a rack fixedly connected to the outer surface of the collar, a gear meshing with the upper end of the rack, a connecting plate rotatably connected to one end of the gear, a U-shaped rod fixedly connected to one end of the connecting plate, and an L-shaped rod fixedly connected to one end of the U-shaped rod.

[0007] Furthermore, a groove is fixedly connected to the middle of the outer surface of the collar, and a slider is slidably connected to the inner side of the groove. One end of the slider is fixedly connected to one end of the L-shaped rod.

[0008] Furthermore, the injection mechanism includes a fixed frame fixedly connected to the upper end of an L-shaped rod. A medicine bottle is fixedly connected to the upper end of the fixed frame. Two symmetrically arranged mounting blocks are fixedly connected to the lower end of the inner wall of the fixed frame. A sliding rod is fixedly connected to one end of the mounting blocks that is close to each other. A sliding plate is slidably sleeved on the surface of the sliding rod. A syringe is fixedly connected to the upper end of the sliding plate. The syringe is connected to the medicine bottle via a conduit.

[0009] Furthermore, the disassembly mechanism includes a baffle one fixedly connected to one end of a fixed plate, a baffle two fixedly connected to one end of the other fixed plate, a fixed shell fixedly connected to one end of the baffle one, guide rods fixedly connected to both ends of the inner wall of the fixed shell, two symmetrically arranged sliding blocks slidingly sleeved on the surface of the guide rods, an L-shaped rod two fixedly connected to one end of the sliding block, and a pressing plate fixedly connected to one end of the L-shaped rod two.

[0010] Furthermore, the fixing mechanism includes a partition plate fixedly connected to one end of the inner wall of the fixing shell, a connecting rod fixedly connected to one end of the sliding block, a connecting block fixedly connected to one end of the connecting rod, an insert block fixedly connected to one end of the connecting block, a U-shaped block fixedly connected to one end of the baffle, and the insert block inserted into the inner side of the U-shaped block.

[0011] Furthermore, springs are directly provided between the partition and the connecting block.

[0012] Furthermore, the inner wall of the collar is provided with a wear-resistant layer.

[0013] The advantages of this invention compared to existing technologies are as follows: (1) This utility model, through its quick-release structure, allows for easy installation of the collar on the surface of a tree. Pressing the pressing plate inward causes the L-shaped rods to move closer together, which in turn causes the sliding blocks to move closer together, which in turn causes the connecting rods to move closer together, which in turn causes the connecting blocks to move closer together, which in turn causes the insert blocks to move closer together, thus compressing the spring. Then, the inner side of the collar is brought into contact with the surface of the tree. When the first and second baffles are in contact, the fixing shell is in contact with the inner wall of the U-shaped block. Releasing the pressing plate allows the spring to return, causing the insert block to be inserted into the inner side of the U-shaped block, thus allowing the first baffle to be inserted. The device is fixed together with the baffle plate 2, allowing the collar to be secured to the surface of the tree. This allows for quick and easy attachment of the collar. When the pine wilt nematode control agent injection device needs to be retrieved, pressing the pressing plate again disengages the insert block from the U-shaped block, allowing the collar to be quickly removed from the tree surface. This rapid disassembly and installation improves the efficiency of the pine wilt nematode control agent injection device, enabling more timely control of pine wilt nematodes and enhancing its practicality.

[0020] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0022] A pesticide injection device for controlling pine wilt nematodes includes: a collar 1, a fixing plate 2, a sliding structure 3, a hinged plate 4, and a quick-release structure 6. One end of the collar 1 is fixedly connected to two symmetrically arranged fixing plates 2. The surface of the collar 1 is provided with the sliding structure 3, which includes an injection mechanism 31 and a swinging mechanism 32. In use, the collar 1 is placed on the outer surface of the tree, and the tree is injected through the injection mechanism 31 to control pine wilt nematodes. The swinging mechanism 32 can change the position of the injection mechanism 31, allowing injection at different locations on the tree surface.

[0023] Three sets of hinge plates 4 are respectively set on the inner side of the collar 1. Each set of hinge plates 4 has two plates. The ends of the hinge plates 4 that are close to each other are fixedly connected to a plate 5. When in use, the hinge plates 4 and the plate 5 can increase the degree of freedom of the collar 1, so that the collar 1 can be more easily put on the surface of the tree.

[0024] The quick-release structure 6 is located at one end of the fixed plate 2. The quick-release structure 6 includes a disassembly mechanism 61 and a fixing mechanism 62. When in use, the quick-release structure 6 can improve the installation efficiency of the pine wilt disease control agent injection device, so that the pine wilt disease can be controlled more promptly, thereby improving the practicality of the pine wilt disease control agent injection device.

[0025] The swing mechanism 32 includes a rack 321 fixedly connected to the outer surface of the collar 1. A gear 322 is meshed with the upper end of the rack 321. A connecting plate 323 is rotatably connected to one end of the gear 322. A U-shaped rod 324 is fixedly connected to one end of the connecting plate 323. An L-shaped rod 325 is fixedly connected to one end of the U-shaped rod 324. A groove 326 is fixedly connected to the middle of the outer surface of the collar 1. A slider 327 is slidably connected to the inner side of the groove 326. One end of the slider 327 is fixedly connected to one end of the L-shaped rod 325. The injection mechanism 31 includes a fixed frame 311 fixedly connected to the upper end of the L-shaped rod 325. A medicine bottle 312 is fixedly connected to the upper end of the fixed frame 311. Two symmetrically arranged mounting blocks 313 are fixedly connected to the lower end of the inner wall of the fixed frame 311. A sliding rod 314 is fixedly connected to one end of each mounting block 313 that is close to the other. A sliding plate 315 is slidably fitted onto the surface of the sliding rod 314. A syringe 316 is fixedly connected to the upper end of component 5. The syringe 316 is connected to the medicine bottle 312 via a pipe. In use, by swinging the L-shaped rod 325, the slider 327 begins to slide inside the groove 326, which causes the gear 322 to rotate on the rack 321. This causes the L-shaped rod 325 to swing around the arc of the collar 1, which in turn causes the fixed frame 311 to swing around the arc of the collar 1. This causes the syringe 316 to swing around the arc of the collar 1. When the syringe 316 swings to the position to be injected, the swinging of the L-shaped rod 325 is stopped. By pushing the slide plate 315, it slides along the slide rod 314, which drives the syringe 316 to move back and forth, allowing the injection needle to penetrate into the tree. The medicine is then introduced into the syringe 316 through the medicine bottle 312, thus injecting the tree and controlling pine wilt disease.

[0026] The disassembly mechanism 61 includes a baffle 611 fixedly connected to one end of a fixed plate 2, and a baffle 612 fixedly connected to one end of the other fixed plate 2. A fixed shell 613 is fixedly connected to one end of the baffle 611. Guide rods 614 are fixedly connected to both ends of the inner wall of the fixed shell 613. Two symmetrically arranged sliding blocks 615 are slidably sleeved on the surface of the guide rods 614. An L-shaped rod 616 is fixedly connected to one end of each sliding block 615. A pressing plate 617 is fixedly connected to one end of the L-shaped rod 616. The fixing mechanism 62 includes a baffle 611 fixedly connected to one end of the inner wall of the fixed shell 613. A connecting rod 622 is fixedly connected to one end of the partition 621 and the sliding block 615. A connecting block 623 is fixedly connected to one end of the connecting rod 622. An insert block 624 is fixedly connected to one end of the connecting block 623. A U-shaped block 625 is fixedly connected to one end of the baffle 612. The insert block 624 is inserted into the inner side of the U-shaped block 625. A spring 626 is provided between the partition 621 and the connecting block 623. When the collar 1 is to be installed on the surface of the tree, the pressing plate 617 is pressed inward, so that the L-shaped rods 616 begin to move closer to each other, and thus the sliding blocks 615 begin to move closer to each other. The connecting rods 622 move closer together, which in turn moves the connecting blocks 623 closer together, causing the insert blocks 624 to move closer together. This compresses the spring 626, bringing the inner side of the collar 1 into contact with the surface of the tree. When the first baffle 611 and the second baffle 612 are in contact, the fixing shell 613 is in contact with the inner wall of the U-shaped block 625. Releasing the pressing plate 617 causes the spring 626 to rebound, allowing the insert block 624 to insert into the inner side of the U-shaped block 625. This fixes the first baffle 611 and the second baffle 612 together, thus securing the collar 1. The device is fixed to the surface of the tree, allowing the collar 1 to be quickly secured. When the pine wilt nematode control agent injection device needs to be retrieved, the pressing plate 617 is pressed again, causing the insert 624 to disengage from the interior of the U-shaped block 625. This allows the collar 1 to be quickly removed from the tree surface, improving the efficiency of the installation and enabling more timely control of pine wilt nematodes, thus enhancing the practicality of the device.

[0027] The inner wall of the collar 1 is provided with a wear-resistant layer 7. During use, the wear-resistant layer 7 can reduce the friction between the tree and the pine wilt nematode control agent injection device, and can stably fix the pine wilt nematode control agent injection device to the outer surface of the tree.

[0028] In practical use: The hinge plate 4 and the flat plate 5 increase the freedom of the collar 1, making it easier to fit the collar 1 onto the surface of the tree. The collar 1 is then placed on the outer surface of the tree, and the injection mechanism 31 injects the tree to control pine wilt disease. The swing mechanism 32 can change the position of the injection mechanism 31, allowing injection at different locations on the tree surface. The quick-release structure 6, when installing the collar 1 onto the tree surface, presses the pressing plate 617 inward, causing the L-shaped rods 616 to move closer together, which in turn causes the sliding blocks 615 to move closer together, and the connecting rods 622 to move closer together, which in turn causes the connecting blocks 623 to move closer together, and the insert blocks 624 to move closer together, thus compressing the spring 626. This brings the inner side of the collar 1 into contact with the surface of the tree. When the baffle 611 and the baffle... When plate 612 is connected, the fixing shell 613 is connected to the inner wall of the U-shaped block 625. Releasing the pressing plate 617 allows the spring 626 to return, causing the insert 624 to be inserted into the inner side of the U-shaped block 625. This fixes the first baffle 611 and the second baffle 612 together, thus securing the collar 1 to the surface of the tree. When the pine wilt nematode control agent injection device needs to be retrieved, pressing the pressing plate 617 again causes the insert 624 to disengage from the U-shaped block 625, allowing the collar 1 to be quickly removed from the tree surface. This rapid disassembly and installation of the collar 1 improves the installation efficiency of the pine wilt nematode control agent injection device, enabling more timely control of pine wilt nematodes and enhancing its practicality.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
