Description

Technical Field

[0001] This utility model relates to the field of drilling and injection technology, and in particular to a drilling and injection device for the control of forest pests. Background Technology

[0002] The perforation and injection device for forest pest control is a professional control device designed for tree diseases and pests (such as trunk borers and xylem diseases). Its core function is to inject the pesticide directly into the xylem or phloem of the tree by precisely drilling holes in the trunk. The pesticide is then transported to various parts of the tree by the tree's own transport system (such as xylem vessels and sieve tubes), thereby achieving efficient control of diseases and pests.

[0003] However, existing technologies, such as Chinese Publication No. CN218007356U, "Drilling and Injection Device for Forest Pest Control," provide a drilling and injection device for forest pest control, including a main shell, a storage tank, a handle, a switching mechanism, a drilling mechanism, and an injection mechanism. The main shell has an operating hole at its front end; the storage tank is fixedly mounted on the upper part of the main shell; there are two handles, corresponding to opposite sides of the main shell; the switching mechanism is located inside the main shell; both the drilling and injection mechanisms are mounted on the switching mechanism; the injection mechanism and the storage tank are connected via a delivery hose; the switching mechanism drives the drilling and injection mechanisms to move along the front-rear direction of the main shell, allowing either the drilling or injection mechanism to extend from the operating hole to drill or inject pesticide into the tree trunk. This enables integrated automatic drilling and injection, effectively improving forest pest control efficiency and reducing manual labor. It solves the problem of low efficiency and time-consuming manual pesticide injection processes in existing technologies.

[0004] However, the device lacks an adjustable embedding depth structure, which prevents it from adapting to tree characteristics, protecting tree health, and targeting pests and diseases. This hinders the scientific and eco-friendly approach to forest pest control. Furthermore, the device cannot be flexibly adjusted according to the type of pesticide, leading to pesticide waste or conduction failure due to the fixed depth. This makes it difficult for the pesticide to be transported to the canopy and other parts with water, reducing the control effect, increasing the number of injection points, and affecting tree growth.

A second shaft block is rotatably connected to the end of the two connecting rods away from the first shaft block.

[0013] The technical effect of adopting the above-mentioned further solution is that when the two internal threaded blocks approach each other, they will drive one end of the connecting rod through the first shaft block, and the other end of the connecting rod will push the insert pin through the second shaft block.

[0014] In a preferred embodiment, a pin is fixedly embedded inside the second shaft block, the outer surface of the pin is movably embedded on one side of the housing, a stabilizing sleeve is movably sleeved on the outer surface of the pin, and one side of the stabilizing sleeve is fixedly connected to the inner surface of the housing.

[0017] The technical effect of adopting the above-mentioned further solution is that the motor is fixed to one side of the liner through the mounting sleeve, and the motor will drive the positive and negative lead screws to rotate inside the liner after being powered on.

[0018] In a preferred embodiment, the injection assembly includes a tubing, one end of which is connected to one end of a needle, the outer surface of which is fixedly embedded inside a liner, and the outer surface of which is fixedly embedded on one side of a housing.

[0019] The technical effect of adopting the above-mentioned further solution is that the medicine will be dripped into the tree through the medicine bag, connecting tube, and flexible tube and embedded needle.

[0020] In a preferred embodiment, the end of the tubing away from the needle is connected to a connector, the outer surface of the connector is provided with a connecting tube, the end of the connecting tube away from the connector is connected to a medicine bag, and the top of the medicine bag is fixedly connected to a hanging strap.

[0022] In a preferred embodiment, a fixing block is fixedly connected to the end of the housing away from the drill bit, and a rocker arm is movably embedded inside the fixing block.

[0023] The technical effect of adopting the above-mentioned further solution is that the fixed block and rocker arm drive the insert, drill bit and drilling auger to rotate, and the rotating drilling auger will drive the insert to embed into the tree.
