Description

Municipal garden afforestation is with trees through hole syringe

Technical Field

The invention relates to the technical field of garden tree punching and injecting equipment, in particular to a tree through hole injector for municipal garden greening.

Background

The most common treatment modes are hormone treatment for trees, contraceptive injection and flying catkin propagation control, but the manual input is too high, and the injection of each tree can be completed by cooperation of a plurality of people.

Landscape plants are often threatened by insect pests or diseases during the growth process, and chemical control is one of the most important measures for a long time. The traditional method mainly comprises stem leaf spraying, but the stem leaf spraying has a plurality of defects, and currently, each skilled person is seeking an improvement method. In recent years, the application of the tree trunk injection technology has better control effect on various pests, such as trunk borers, piercing-sucking pests and the like. The trunk injecting technology for tree is to inject systemic medicine into xylem and phloem, to be transmitted to stem and leaf via the xylem pipe and to be transmitted via the phloem sieve pipe to root. The medicine is mainly accumulated in new leaves, buds and fruits, wherein the number of leaves is the largest, and tender leaves are also accumulated to a certain extent and mainly concentrated in xylem and phloem, so that pests die after eating the medicine.

Currently, there are two methods for injecting trees:

firstly, drilling and then injecting; this method requires drilling holes, some of which require a needle, some of which require multiple needles radially around the tree, depending on the diameter of the tree, and some of which require injection once a year.

Secondly, directly inserting a needle for injection; this method lacks stable positioning, and the inserted needle is easily broken during insertion and extraction, and easily hurts the hand by hand.

The two modes belong to quick injection, the injection liquid easily flows out from an orifice on the surface of the bark, the injection dosage cannot meet the requirement due to backflow, and in addition, the high-pressure injected liquid medicine is easy to influence the human body when being sprayed out from the orifice. Meanwhile, the injection device needs to be operated by a plurality of people, the working efficiency is low, the injection depth of trees with different diameters cannot be accurately adjusted, the trees are easily injured when the injection depth is too deep, and the injection of the medicament when the injection depth is too shallow has no effect. Therefore, a tree through-hole injector for municipal garden greening is proposed to solve the problems.
