a tree injection gun

Abstract

The invention discloses a pesticide injection gun for trees. The pesticide injection gun comprises a gun body, a gun barrel, a gun bolt, a gun rod and a gun head, wherein a gun handle of the gun bodyis of a hollow structure; the hollow part of the gun handle is filled with pesticide liquor; female screws are arranged at the inner wall of the gun barrel, a liquid absorbing hole is formed at the back end of the gun barrel, a lower end port of the liquid absorbing hole is connected with a liquid absorbing pipe, and a first check valve is arranged at an upper end port of the liquid absorbing hole; the gun bolt is arranged in the gun barrel and can slide back and forth in the gun barrel, male screws are arranged on the side peripheral surface of the gun bolt, a liquid discharging hole is formed in the center position of the gun bolt, and a second check valve is arranged on the liquid discharging hole; the gun rod is of a hollow structure, the back end of the gun rod extends into the gun barrel and is fixedly connected with the gun bolt, and the front end of the gun rod is connected with the gun head; and a drill bit is arranged at the front end of the gun head, and an injection hole isformed in the side of the drill bit. The pesticide injection gun for trees has the beneficial effects that two operations of drilling and liquid injection can be simultaneously accomplished by abutting the gun head against a trunk and pressing the gun body, and the pesticide injection gun has convenient operation, high efficiency and controllable and adjustable liquid injection amount.

Description

technical field [0001] The invention belongs to the technical field of forestry supplies, in particular to a tree medicine injection gun. Background technique [0002] When trees are used to control diseases and pests or liquid fertilization, foliar spraying or soil fertilization are often used. The former is limited due to the limited spraying range, and the control effect is not good. The objects applied by the latter are easily absorbed by the soil, not only the fertilizer utilization rate is not high, but also it is easy to pollute the soil and water sources. [0003] In order to solve the above problems, a trunk drug delivery technology came into being in the late twentieth century. This technology is to inject the liquid medicine into the tree body, so that it can be delivered to various parts of the tree body along with the flow of the sap to take effect. This method can reduce pollution, protect natural enemies, and is beneficial to ecological balance, especially ...

AI Technical Summary

Problems solved by technology

At present, the implementation of this technology mostly uses tools such as nails, chisels, pots, etc. to punch holes and then inject liquid medicine. The two processes of drilling holes and injecting liquid medicine are not only low in efficiency, but also labor-intensive. Moreover, the operation is difficult and the injection volume is uncertain, which affects the popularization and application of the technology
