Trunk injector for injecting disease-treating chemical into trunk

Abstract

The invention provides a trunk injector for injecting a disease-treating chemical into a trunk. The trunk injector comprises a screw rod, spring seats, a slider, a chemical adding tank, a driven shafttube and a threaded connecting sleeve and is characterized in that a first rotary shaft and a second rotary shaft are respectively connected to two ends of a double-shaft motor, the screw rod is connected to the first rotary shaft, the spring seats are respectively arranged on the first rotary shaft parts located at two ends of the screw rod, a push rod at the top of the slider penetrates a slidegroove in an injector body to be arranged on the rear side of a piston rod, the inner side of a transparent chemical tube is provided with a rubber plate and the piston rod, a sealing partition is further embedded into the inner side of the front end of the transparent chemical tube, five arc-shaped brushes are connected to one end, penetrating the sealing partition, of the driven shaft tube, a drill bit is connected to one end, penetrating the transparent chemical tube, of the driven shaft tube through the threaded connecting sleeve, a hand wheel sealing column penetrates the middle of the threaded connecting sleeve, and the chemical adding tank is connected to the top of the transparent chemical tube through a pipeline. The trunk is capable injecting the chemical into the trunk during drilling.

Description

technical field [0001] The invention belongs to the technical field of tree treatment, and more specifically relates to a trunk injector for injecting symptomatic pesticides into the trunk. Background technique [0002] Garden plants are often threatened by pests during their growth, and chemical control is one of the most important measures for a long time. The traditional method is to spray pesticides on plant leaves and tree trunks. Although the control effect of pesticide spraying is better, there are many shortcomings in spraying. Drilling and injecting pesticides to prevent and control pests is an effective, labor-saving, time-saving and cost-saving technology. [0003] The inventor found similar patents for tree injection in the process of searching for patents. For example, in the Chinese patent application number: 201510545731.9, a continuous pressure device for tree injection and infusion is disclosed, which is characterized in that it includes Probe and air bag,...

AI Technical Summary

Problems solved by technology

[0005] Based on the above, the inventors found that when using the traditional tree injector, the tree needs to be drilled first, and then the pesticide is poured into the hole, which is a waste of time, and the dosage of the medicine injected each time is also different. Injecting more drugs will cause waste of drugs, and injecting less drugs will affect the control effect
