Description

Technical Field

[0001] The utility model relates to the technical field of drug injection devices, in particular to a drug injection device for preventing and controlling pine wood nematodes. Background Art

[0002] Pine wilt disease, also known as pine wilt, is a destructive disease caused by pine nematodes. The main characteristic of pine nematode disease is that it causes rapid withering and death of pine trees. Infected pine trees will show symptoms of gradual yellowing and withering of the crown, and the trunk will become soft, eventually leading to the death of the tree. This is because pine nematodes parasitize and reproduce inside the pine trees, causing the pine trees to decay and die. The pine nematode control agent injection device is a device used to control pine nematode disease. It is used to inject agents into infected pine wood to control and prevent the spread and reproduction of pine nematodes.

[0003] For example, a Chinese authorized patent, with a publication number of CN220140346U, is a device for injecting pine nematode control agents, which belongs to the technical field of pine nematode control equipment. The device for injecting pine nematode control agents includes a first splint, a second splint, a fastening assembly and a push-in assembly, wherein the second splint is hinged at one end of the first splint, and the fastening assembly includes a clamping block, a first screw rod and a first threaded block, the clamping block is slidably mounted on the side wall of the second splint, and the side wall of the clamping block is symmetrically fixed with a guide rod, which is slidably connected to the second splint. The utility model is provided with a fastening assembly, the first splint is pressed against the side wall of the trunk, the second splint is rotated, and the trunk is sleeved between the first splint and the second splint; then the first knob is rotated to drive the first screw rod to rotate, and the first screw rod is driven to move toward the inner cavity of the second splint through the first threaded block, thereby driving the clamping block to move and press against the side wall of the trunk, completing the fixation of the device, and can be used for trees of different diameters.

[0004] The above-mentioned traditional drug injection device is generally used to inject at the locked position of the pine wood, but is not conducive to injecting at different horizontal positions of the pine wood, resulting in a relatively fixed injection range of the equipment, which in turn affects the control efficiency of pine wood nematodes.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0029] Reference Figure 1-6 As shown, a drug injection device for controlling pine wood nematodes includes a drug injector body 1, which includes two groups of collars 211 that rotate toward or away from each other, a bracket 215 that is slidably connected to the outer wall of the two groups of collars 211, a medicine bottle 216 installed on the top of the bracket 215, a needle 219, an infusion tube 217 connected to the medicine bottle 216 and the needle 219, and a driving mechanism for driving the bracket 215 to rotate along the direction of the collar 211. Under the action of the driving mechanism, the bracket 215 can be driven to rotate along the direction of the collar 211, and the needle 219 can correspond to different positions of the pine wood, thereby increasing the contact surface with the pine wood and improving the use range of the drug injection. The two groups of collars 211 are fixed with a wear-resistant layer 212 on the opposite side, and the wear-resistant layer 212 is made of silicone material. The silicone material has a good wear-resistant effect, ensuring that the collar 211 will not fall off after being attached to the pine wood, and at the same time, it can also ensure that the pine wood will not be worn.

[0030] The outer walls of the two sets of collars 211 are provided with sliding grooves 213, and the inner walls of the sliding grooves 213 are slidably connected with sliding blocks 214 fixedly connected with the bracket 215. The inner wall of the bottom end of the bracket 215 is provided with slots 220, and the inner wall of the slots 220 is slidably connected with a movable plate 221. A sleeve block 218 is fixed on the top of the movable plate 221, and the sleeve block 218 is fixed to the outer wall of the infusion tube 217. By pushing the movable plate 221, the needle 219 can be driven to be embedded in the pine wood, making the operation more comfortable. A fixed plate 222 is fixed on the inner wall of the bottom end of the bracket 215, and a movable rod 224 is fixed on the outer wall of the movable plate 221. A hole 223 is provided on the inner wall of the fixed plate 222 for the movable rod 224 to move back and forth. The movable rod 224 and the hole 223 are provided to ensure the stability of the movement of the movable plate 221. A pull plate 225 is fixed to one end of the movable rod 224 away from the movable plate 221 . The diameter of the pull plate 225 is larger than that of the movable rod 224 . The pull plate 225 can provide a better protective effect and prevent the movable rod 224 from completely falling off from the hole 223 .

[0031] The driving mechanism includes a motor 226, a rotating rod 227, a rotating gear 228 and a rack ring 229. The motor 226 is installed at the bottom end of the bracket 215. The output end of the motor 226 is connected to the rotating rod 227. The rotating gear 228 is fixed to the end of the rotating rod 227 away from the motor 226. The outer wall of the ring 211 is fixed with a rack ring 229 that meshes with the rotating gear 228. When the motor 226 is turned on, the rotating rod 227 and the rotating gear 228 are driven to rotate, and the bracket 215 can be driven to rotate automatically under the reaction force.

[0032] A rotating shaft 312 is fixed to both the front and rear sides of the connecting block 311 . One end of the rotating shaft 312 away from the connecting block 311 is rotatably connected to the collar 211 . The two sets of collars 211 can rotate toward or away from each other.

[0033] A screw rod 314 runs through the two sets of rings 211, a nut 313 that fits the outer wall of the ring 211 is fixed at one end of the screw rod 314, and a rotating nut 316 is threadedly connected to the outer wall of the other end. A rotating plate 315 that is rotatably connected to the ring 211 is fixed to the outer wall of the rotating nut 316. The rotating nut 316 is rotated to make it rotate, and the two sets of rings 211 move toward or away from each other under the action of the thread. This locking method is relatively firm and can prevent the drug injector body 1 from falling off.

[0034] Working principle: When multi-directional drug injection is required, the motor 226 is turned on to drive the rotating rod 227 and the rotating gear 228 to rotate. The rotating gear 228 can engage with the rack ring 229. Under the reaction force, the bracket 215 slides along the direction of the ring 211, and drives the medicine bottle 216, the infusion tube 217 and the needle 219 to move, so that the needle 219 corresponds to different positions of the pine wood, thereby achieving a multi-directional drug injection effect.

[0035] When it is needed, the two sets of rings 211 are sleeved on the pine material. At this time, the screw 314 is passed through the two sets of rings 211. By rotating the rotating nut 316, the two sets of rings 211 are rotated towards each other under the action of the thread and clamped with the outer wall of the pine material. At this time, the staff can push the pull plate 225 backward to drive the movable rod 224, the movable plate 221, the sleeve block 218 and the needle 219 to move backward, so that the needle 219 is inserted into the interior of the pine material, achieving the effect of insertion for drug injection.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
