Airtight pressure type injector for trunks

Abstract

The invention relates to an airtight pressure type injector for trunks. The airtight pressure type injector for trunks comprises a liquid medicine tank, a liquid medicine tank sealing cover and a compression tank, wherein an opening part is formed in the back of the liquid medicine tank, compression tank inserting parts are arranged between an outer wall and an inner wall which are provided with a pair of clamping grooves, and an injection barrier film is arranged between the liquid medicine tank and an injection pipe at the front end of the liquid medicine tank; a hole forming pin guiding pipe of which the front end is blocked by a guiding pipe barrier film is formed on the liquid medicine tank sealing cover in a protuberant manner, and the liquid medicine tank sealing cover and the edge of the opening part of the back of the liquid medicine tank are jointed integrally, so that liquid medicine is prevented from being leaked outwards; and clamping protrusions which are clamped in the clamping grooves are formed on the outer surface of the compression tank, so that the compression tank is assembled in the compression tank inserting parts, and the guiding pipe barrier film, which is in the center of the compression tank and is close to the hole forming pin guiding pipe, is provided with a hole forming pin with circulation grooves in a protuberant manner. If the compression tank is beaten, and pressure of compressed air is used, the liquid medicines are smoothly injected, so that the working efficiency is high, and the construction cost is low. When the liquid medicine tank is stored for a long term, liquid medicine ingredients cannot be leaked outwards, so that ingredient reduction can be effectively avoided.

Description

technical field [0001] The present invention relates to a closed type pressure type tree trunk injector, and more particularly to a closed type pressure type tree trunk injector in which a compression barrel is provided on the bottom of a liquid medicine barrel integrally formed with an injection pipe so that when the compression barrel is hit with a hammer , does not use a separate compression sleeve, and there is no worry about the leakage of the liquid medicine to the outside. It can be quickly and easily inserted into the tree, so that the liquid medicine can be supplied smoothly, so that it can improve the number of roadside trees or forests with many trees, parks, etc. The large-scale operation efficiency of the land. Background technique [0002] Usually, trees are prone to diseases due to pollution caused by the development of various industries, environmental changes in the soil, or various diseases and insect pests, or when various inorganic nutrients required for ...

Problems solved by technology

[0017] In addition, prior art 2 has the following problem: when a joint failure occurs on one side of the pressing part that is jointed with the upper edge of the main body container, there is a possibility that the liquid medicine may directly leak out to the outside. If the engagement state of the engagement part is loose, when the pressing part is pressed and released in order to increase the internal pressure, the guide part is easy to disengage from the engaging part, and the pressing part returns to its original position, so the injection by pressure is carried out smoothly , on the contrary, if the guide part and the engaging part are too close together, it will take quite a lot of force when pressed by hand
