Technical Field
[0001] This utility model relates to the field of forestry pest control technology, specifically a forestry pest and disease control infusion auxiliary tool. Background Technology
[0002] Infusion therapy for forest pest and disease control is a technique that involves directly injecting pesticide solutions into trees to control and prevent pests and diseases. Compared to traditional spraying, it may be more efficient and environmentally friendly, but in practical applications, equipment support and tree species suitability must be considered to ensure its effectiveness and safety.
[0003] Chinese utility model patent CN221228315U discloses an infusion device for controlling forest pests and diseases, comprising a fixed structure. A U-shaped handle is fixedly connected to both the upper left and upper right ends of the fixed structure. A fixing strap is movably connected to the U-shaped handle on the left end. An infusion bottle is fixedly held inside the fixed structure. An infusion tubing is fixedly connected to the lower end of the infusion bottle, passing through the fixed structure. Two sets of straps are inserted and bound to the outside of the infusion tubing. A square pusher is fixedly connected to the lower end of the infusion tubing, and an infusion needle is fixedly connected to the lower part of the infusion needle. A square pusher is inserted and fixedly connected to the upper part of the infusion needle, and the upper end of the square pusher is inserted and fixedly connected to the infusion tubing. This utility model describes an infusion device for controlling forest pests and diseases.
[0004] Existing forestry infusion methods involve drilling a 45-degree upward-facing hole in the tree, hanging a medicine bag on the trunk with a rope, and then inserting a needle connected to the lower end of the medicine bag into the hole to inject the medicine into the tree. However, for trees with smooth trunks, tall branches, and varying diameters, it is difficult to hang the medicine bag. The aforementioned patent cannot effectively secure the medicine bag to trunks of different diameters. In addition, existing methods insert the needle directly into the slanted hole in the tree, resulting in poor sealing between the needle and the hole, which can easily lead to leakage of the medicine. Therefore, we propose an auxiliary tool for forestry pest and disease control infusion. Utility Model Content

[0028] The following will be combined with the appendix Figures 1 to 5 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0029] This utility model provides an improved infusion aid for the prevention and control of forest pests and diseases, such as... Figure 1 - Figure 5 As shown, the device includes a support assembly 1, which includes a tube 101. A connecting half tube 102 is fixedly connected to the tube 101. A placement frame 103 is fixedly connected to the end of the connecting half tube 102 away from the tube 101. An adjustment assembly 2 is fixedly connected to the placement frame 103.
[0030] The adjusting assembly 2 includes two fixed plates 201 fixedly connected to the placement frame 103. A round tube 202 is rotatably connected to each of the two fixed plates 201. A winding drum 203 is connected between the two round tubes 202. A torsion spring 204 is fixedly connected between the winding drum 203 and the fixed plates 201. A winding assembly 3 for fixing the support assembly 1 is fixedly connected to the winding drum 203. An infusion assembly 4 for infusion is placed inside the support assembly 1. A sealing assembly 5 to prevent leakage of the medicine is installed on the tube 101.
[0031] In this embodiment: When it is necessary to install the bracket assembly 1, first insert the insert 101 into the insertion hole in the tree trunk. At this time, the bracket assembly 1 is tilted on the side wall of the tree. Then press the two pressing plates 208. The two pressing plates 208 drive the friction plate 209 to move through the square rod 207, so that the friction plate 209 no longer contacts the inner side wall of the winding drum 203. At this time, the winding drum 203 is in an active state. At this time, you only need to pull the binding hook 303 to hook the tree to complete the installation of the bracket assembly 1.
[0032] In the above embodiments, in order to facilitate the adjustment of the length of the connecting rope 302 to accommodate trees of different diameters, the following method can be adopted:
[0033] The adjusting assembly 2 also includes a fixed frame 205 fixedly connected to the opposite side wall of the two fixed plates 201. A square tube 206 is fixedly connected to each of the two fixed frames 205. A square rod 207 is inserted into each of the two square tubes 206. A friction plate 209 is fixedly connected to the square rod 207 through the round tube 202. The friction plate 209 abuts against the inner wall of the take-up drum 203. A toothed surface is fixedly connected between the friction plate 209 and the inner wall of the take-up drum 203. A pressing plate 208 is fixedly connected to the end of the square rod 207 away from the take-up drum 203. A connecting spring 210 is fixedly connected between the pressing plate 208 and the fixed frame 205. The take-up assembly 3 includes two take-up reels 301 fixedly connected to the take-up drum 203. A connecting rope 302 is wound around the take-up drum 203 and is located between the two take-up reels 301. A binding hook 303 is fixedly connected to the end of the connecting rope 302 away from the take-up drum 203.
[0034] In a preferred embodiment, when the friction plate 209 separates from the winding drum 203, the toothed surface no longer contacts the toothed surface of the friction plate 209, and the winding drum 203 is in a movable state. Conversely, when the friction plate 209 contacts the inner wall of the winding drum 203, the toothed surfaces correspond to each other, and the square rod 207 is limited by the square tube 206 and cannot rotate. At this time, the winding drum 203 cannot rotate under the action of friction, thus locking the length of the connecting rope 302.
[0035] refer to Figure 4 and Figure 5 In a preferred embodiment, the infusion assembly 4 includes a needle 401 inserted into the insert 101, a medicine bag 403 is disposed inside the placement frame 103, a needle tube 402 is connected between the needle 401 and the medicine bag 403, and the sealing assembly 5 includes a plurality of air holes 501 drilled on the insert 101. Rubber semicircles 502 are fixedly connected to both the inner and outer side walls of the insert 101, and the rubber semicircles 502 on the inner and outer sides are connected through the air holes 501.
[0036] In this embodiment: After the bracket assembly 1 is installed, the medicine bag 403 is placed in the placement frame 103, and then the needle 401 is inserted into the insert 101, so that the needle 401 squeezes the rubber semicircle 502 on the inner side of the insert 101. At this time, the rubber semicircle 502 on the outer side of the insert 101 expands under the action of air pressure, which can improve the sealing between the insert 101 and the tree hole.
[0037] Working principle: During installation, the worker first drills a 45-degree upward-facing angled hole at the injection point on the tree. Then, the insert 101 is inserted into the hole in the tree trunk. At this time, the support assembly 1 is tilted against the side wall of the tree. Then, the two pressing plates 208 are pressed. The two pressing plates 208 drive the friction plate 209 to move through the square rod 207, so that the friction plate 209 is no longer in contact with the inner wall of the take-up drum 203. The toothed surface of the take-up drum 203 is no longer in contact with the toothed surface of the friction plate 209. At this time, the take-up drum 203 is in an active state. At this time, simply pull the binding hook 303 to hook the tree. Then, the worker releases the pressing plates 208 again. The pressing plates 208 are reset under the action of the connecting spring 210, so that the take-up drum 203 contacts the friction plate 209 again, thus locking the length of the connecting rope 302. The installation of the support assembly 1 is then completed. The state after installation is as follows. Figure 1 As shown;
[0038] After the bracket assembly 1 is installed, the medicine bag 403 is placed in the placement frame 103, and then the needle 401 is inserted into the insert 101. The medicine flows into the tree through the insert 101. At this time, the needle 401 will squeeze the rubber semicircle 502 on the inner side of the insert 101. At this time, the rubber semicircle 502 on the outer side of the insert 101 expands under the action of air pressure, which can improve the sealing between the insert 101 and the hole drilled in the tree.
[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
