Description

Technical Field

[0001] The utility model relates to the technical field of stem-boring pest control, in particular to a medicine injector for stem-boring pest control. Background Art

[0002] Stem-boring pests generally cause harm by having their larvae live inside branches and feed on them. The impact of stem-boring pests on garden plants is great and often extremely destructive. The larvae mainly bore under the bark, phloem, and xylem, forming tunnels that affect the flow of nutrients and water to the host plant. In mild cases, the tree will become weak and easily broken by the wind or invaded by other pests and pathogens. In severe cases, the entire plant can die.

[0003] When controlling trunk-boring pests, since the trunk-boring larvae live in the subcutaneous tissue of the tree trunk, a syringe is used to inject medicine into the trunk to kill the trunk-boring larvae. However, due to the small capacity of the existing syringe, only a single trunk can be injected. When injecting a large trunk, the medicine needs to be inhaled multiple times. Especially when the trunk is high and the medicine container is inconvenient to carry, climbing up and down is very inconvenient and there is a safety hazard. In this regard, we propose a drug syringe for controlling trunk-boring pests to solve the above-mentioned problems. Utility Model Content

[0020] Syringe 1, the front end of the syringe 1 is fixedly mounted with an injection head 2, the rear end of the syringe 1 is threadedly connected to a first end cover 3, the center of the first end cover 3 is slidably connected to a piston rod 4, the piston rod 4 is located at one end of the inner cavity of the syringe 1 and is fixedly mounted with a piston 5, the rear end of the piston rod 4 is fixedly mounted with a pressing plate 6, a handle 7 is fixedly mounted on the bottom wall of the syringe 1, a push rod 8 is fixedly mounted on the bottom wall of the pressing plate 6, a drug storage cartridge 9 is provided above the syringe 1, a connecting tube 10 is fixedly bonded to the drug storage cartridge 9, the bottom end of the connecting tube 10 is fixedly bonded to the syringe 1, A T-shaped through slot 12 is provided in the through tube 10, and a blocking block 13 is slidably connected to the T-shaped through slot 12. A connecting rod 14 is fixedly bonded at the center of the top wall of the blocking block 13. The top end of the connecting rod 14 passes through the medicine storage cartridge 9 and extends to the top of the medicine storage cartridge 9. A pressing block 15 is fixedly bonded to the top of the connecting rod 14. A sealing block 16 is fixedly bonded to the top wall of the medicine storage cartridge 9 at the position of the connecting rod 14. The sealing block 16 is slidably connected to the connecting rod 14. A first elastic spring 17 is sleeved on the connecting rod 14, and the two ends of the first elastic spring 17 are fixedly connected to the pressing block 15 and the sealing block 16 respectively.

[0021] A second end cap 11 is threadedly installed at the rear end opening of the drug storage cartridge 1, and a mounting sleeve 18 is fixedly bonded to the drug storage cartridge 9. The mounting sleeve 18 is fixedly bonded to the top wall of the injection barrel 1. The threaded second end cap 11 is easy to open, which is convenient for replenishing drugs in the drug storage cartridge 9. The mounting sleeve 18 is used to install and fix the drug storage cartridge 9.

[0022] The piston rod 4 is sleeved with a second elastic spring 19, and the two ends of the second elastic spring 19 are fixedly connected to the first end cover 3 and the pressing plate 6 respectively. The first end cover 3 is provided with a plurality of vent holes 20. The second elastic spring 19 can facilitate the automatic reset of the piston 5 after squeezing, which is convenient for the next pressing injection.

[0023] A sealing gasket 21 is fixedly bonded to the top wall of the blocking block 13 , and the sealing gasket 21 can improve the sealing performance of the blocking block 13 during blocking.

[0024] The injection barrel 1 and the drug storage barrel 9 are both made of transparent plastic material. The injection barrel 1 and the drug storage barrel 9 made of transparent plastic material can conveniently observe the amount of injected medicine and the amount of medicine stored in the drug storage barrel at any time.

[0025] Working principle: The utility model can store medicine during use by installing a drug storage cartridge 9 above the injection barrel 1, and after the medicine in the injection barrel 1 is injected, the medicine stored in the drug storage cartridge 9 is introduced into the injection barrel 1 through the provided connecting tube 10 for injection, so that the effect of replenishing medicine into the injection barrel 1 multiple times can be achieved through the drug storage cartridge 9, which solves the problem that the existing syringe for controlling trunk borers can only be used for injection into a single trunk due to its small capacity. When injecting into a large area of trunks, it is necessary to inhale the medicine multiple times, especially when the trunk is at a high position and the medicine container is inconvenient to carry, and it is very inconvenient to climb up and down to inhale the medicine. The specific operation process is as follows: pushing the push rod 8 can drive the piston 4 to slide in the syringe 1 to inject the stem-boring pest control medicine. When the syringe 1 needs to be supplemented with medicine, the pressing block 15 can be pressed downward, so that the pressing block 15 drives the blocking block 13 to move downward through the connecting rod 14, opening the T-shaped slot 12, so that the medicine in the medicine storage cartridge 9 can be introduced into the syringe 1 through the T-shaped slot 12. After releasing the pressing block 15, the blocking block 13 can be reset under the action of the first elastic spring 17, and the T-shaped slot 12 is blocked, so that the medicine storage cartridge 9 can supplement the medicine into the syringe 1 multiple times.
