Description
Technical Field
[0001] This utility model relates to the field of agricultural pest control technology, and in particular to a simple punching and injecting device for pest and disease control. Background Technology
[0002] Simple, perforated injection devices for pest and disease control are commonly used in agriculture, particularly for crop pest and disease control. These devices work by creating small holes in the plant stem or fruit, through which pesticides are injected to control pests and diseases or improve crop health. Their simple design makes them easy for farmers and professionals to use in the field.
[0003] Existing pesticide injection devices are designed with biodegradable plastic and have a storage bag. When in use, the storage bag is placed directly into the drilled hole, and then the storage bag is punctured with a puncture needle to achieve the desired effect. The cone cap is easy to fix, saving time and effort, and the control efficiency is relatively high. However, the hole must be drilled first before the vegetation can be injected, which is too cumbersome and the stability when pushing it is poor. Therefore, a simple drilling and injection device for pest and disease control is proposed to solve the above problems. Utility Model Content

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 , Figure 3An embodiment of this utility model provides a simple punching and injection device for pest and disease control, comprising a storage cylinder 1, a connecting plate 2 that is engaged with the inside of the right side of the storage cylinder 1, a sleeve 3 that is fixedly connected to the right side of the connecting plate 2, a push rod 4 that is slidably connected inside the sleeve 3, a piston 14 that is fixedly connected to the left end of the push rod 4, a support block 7 that is fixedly connected to the lower side of the connecting plate 2, an insertion rod 5 that is slidably connected inside the support block 7, a connecting block 6 that is fixedly connected to the upper outside of the insertion rod 5, the upper side of the insertion rod 5 that is slidably connected inside the sleeve 3, a first spring 23 that is sleeved on the outside of the insertion rod 5, a push block 8 that is fixedly connected to the bottom end of the insertion rod 5, a locking assembly that is fixedly connected to the upper right side of the push block 8, the locking assembly being used to fix the position of the insertion rod 5, one end of the first spring 23 that is fixedly connected to the bottom of the connecting block 6, and the other end of the first spring 23 that is fixedly connected to the upper part of the support block 7;
[0031] The engaging assembly includes an elastic locking element 9, which is fixedly connected to the upper right side of the push block 8. A pressing rod 13 is attached to the right side of the elastic locking element 9. One side of the pressing rod 13 is slidably connected to the inside right side of the support block 7. A pressing block 11 is fixedly connected to the right end of the pressing rod 13. A second spring 12 is sleeved on the outside of the right side of the pressing rod 13. One end of the second spring 12 is fixedly connected to the left side of the pressing block 11, and the other end of the second spring 12 is fixedly connected to the right side of the support block 7.
[0032] By pushing the push block 8, the insertion rod 5 is inserted into the sleeve 3, and the connecting block 6 is moved. The first spring 23 is pulled to generate a rebound force. At the same time, the support block 7 causes one end of the elastic clip 9 to hook into the clip groove 10, fixing the position of the insertion rod 5. This allows the insertion rod 5 to firmly hold the push rod 4, thus smoothly pushing the push rod 4 and allowing the medicine to enter the needle 17 smoothly and evenly to inject medicine into the vegetation. Pressing the pressing block 11 downwards causes the elastic clip 9 to be pushed out and no longer locked with the support block 7. Then, the push block 8 can be pulled to move the insertion rod 5 out of the sleeve 3, so that it no longer holds the push rod 4.
[0033] Reference Figure 1 , Figure 2 , Figure 4 The storage cylinder 1 is fixedly connected to the left side of the cylinder bottom 16, and the cylinder bottom 16 is fixedly connected to the left side of the needle tube 21. The needle tube 21 is externally connected to the mounting part 18. The mounting part 18 is fixedly connected to the left side of the mounting part 18, and four plugs 19 are fixedly connected to the right side of the mounting part 18. The cylinder bottom 16 has four insertion holes 22 on the left side inside. The plugs 19 are slidably connected to the inside of the insertion holes 22. The front side of the mounting part 18 is threaded with a bolt 20, and the rear end of the bolt 20 is fitted to the outer wall of the needle tube 21.
[0034] By rotating the bolt 20, it is unscrewed from the interior of the mounting part 18, no longer tightly pressing against the needle tube 21, thus securing the needle tube 21 to the mounting part 18. Pulling the mounting part 18 moves the insert 19 inside the insertion hole 22, separating it from the bottom of the cylinder 16, thus separating the mounting part 18 from the needle tube 21. This allows for quick and convenient disassembly and replacement of the needle 17, improving the practicality and convenience of the device.
[0035] Reference Figure 1 , Figure 2 , Figure 3 The support block 7 has a groove 10 inside, and the elastic clip 9 is slidably connected inside the groove 10. The front side of the elastic clip 9 is attached to the front side wall of the groove 10. The piston 14 is slidably connected inside the storage cylinder 1, and the push rod 4 is slidably connected inside the connecting plate 2. The front side of the storage cylinder 1 is fixedly connected with a scale line 15.
[0036] The elastic clip 9 slides inside the slot 10 and fits against the inner wall of the slot 10, allowing the insert rod 5 to press against the push rod 4 to ensure stability; the push rod 4 is pushed and slides inside the connecting plate 2, causing the piston 14 to move inside the storage cylinder 1 and squeeze out the medicine; the scale line 15 facilitates the observation of the medicine inside the storage cylinder 1.
[0037] Working principle: When the device is needed, the insert rod 5 is inserted into the sleeve 3 by the push block 8, which moves the connecting block 6 to pull the first spring 23 and make it hold the push rod 4 against it. At the same time, the elastic clip 9 is hooked into the slot 10 by the support block 7 to fix the position of the insert rod 5. This makes it possible to push the push rod 4 smoothly and evenly, so that the medicine can be injected into the needle 17 to inject medicine into the vegetation.
[0038] By rotating the bolt 20 to unscrew it from the interior of the mounting piece 18 and no longer pressing against the needle tube 21, the mounting piece 18 is pulled to pull the insert 19 out of the insertion hole 22, thus separating the mounting piece 18 from the needle tube 21. This allows for quick and convenient disassembly and replacement of the needle 17, improving the practicality and convenience of the device.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
