Minimally invasive tree injector with controllable injection pressure and injection amount and working method thereof

Abstract

The invention discloses a minimally invasive tree injector with controllable injection pressure and injection volume and a working method thereof. The minimally invasive tree injector comprises an injector shell, an injection needle connector, an injection assembly and an injection supply bottle, an injection cylinder matched with the injection assembly is arranged in the injector shell, the injection assembly comprises an injection piston matched with the injection cylinder, an injection piston rod connected to the injection piston and a piston rod stop nut matched with the injection piston rod, the rear end of the injector shell is further connected with an air storage tank driving the injection piston rod to act, a pressure regulator is arranged on the air storage tank, a flow monitoring cylinder is arranged at the front end of the injector shell, the injection supply bottle is connected to the flow monitoring cylinder, and a liquid inlet and outlet change-over switch is arranged on the injector shell. Theminimally invasive tree injector is small in damage to trees, prolongs the service life of the trees, can automatically inject agents to the trees, is high in injection speed and efficiency, and can well adjust and monitor the injection pressure and the injection amount; and meanwhile, the minimally invasive tree injector is not affected by weather during injection and is wide in application range.

Description

technical field [0001] The invention belongs to the field of tree treatment, in particular to a minimally invasive tree injector with controllable injection pressure and injection volume and a working method thereof. Background technique [0002] Diseases of trees need to be treated by injecting drugs. At present, after punching a hole in the tree, the head of the medicine bottle is directly inserted into the hole for self-drip; [0003] Existing tree treatments have the following drawbacks: [0004] 1. The diameter of the opening on the tree is large, which will cause great damage to the tree. Over time, the opening is easy to rot and affect the life of the tree; [0005] 2. The speed of self-drip is slow and the efficiency is low. A bottle of medicine needs to be dripped for half a day or even a whole day; [0006] 3. In seasons or areas where the temperature is high, trees tend to have oil retention, and the self-dripping lacks the injection power, so it can no longer d...

AI Technical Summary

Problems solved by technology

[0004] 1. The diameter of the opening on the tree is large, which will cause great damage to the tree. Over time, the opening is easy to rot and affect the life of the tree;

[0005] 2. The speed of self-drip is slow and the efficiency is low. A bottle of medicine needs to be dripped for half a day or even a whole day;

[0006] 3. In seasons or areas where the temperature is high, trees tend to have oil retention, and self-dripping lacks the injection power, so it can no longer drip by itself, so it is more affected by the injection climate. In seasons with higher temperatures and in southern regions It is basically impossible to perform automatic dripping, which limits its scope of application
