Description

[Detailed Description of the Invention] The present invention relates to a device for injecting chemicals such as nutrient solution and insecticide and fungicide into trees that are weakened or infested with pests and diseases.

When supplying chemical solutions to trees, the method of injecting the chemical solution into the vascular bundle of the tree trunk or root and allowing it to be absorbed is extremely effective in restoring tree vigor and in particular controlling pests (e.g. pine tree nematode) that live inside the tree. show.

For this reason, it is conceivable to make a hole in the tree trunk or root and inject the chemical solution naturally or under pressure, but it is desirable to have a device that can continuously and automatically inject a large amount of the chemical solution.

The present invention was devised based on such a request, and a chemical solution supply port 3 is provided at the bottom of the closed container 1, a plurality of injection tubes 6 are connected to the supply port 3, and the tip of the injection tube 6 is connected to the supply port 3. 10 is a tree that penetrates through the elastic stopper 9 but does not protrude; 1 has a structure in which the bottom of the elastic stopper 9 is formed into a concave surface 11; and a liquid supply port 4 with a degassing hole 5 is provided in the upper part of the container 1. It is a liquid injection device.

Referring to the embodiment of FIG. 1, the container 1 is preferably a commercially available plastic 187 liquid carrying container, for example.

Several injection tubes 62 are connected to the chemical solution supply port 3 .

The connecting portion is preferably made by passing two to several glass tubes 8 of about 5 mm through the rubber stopper 7, and connecting the flexible injection tube 6 to the glass tubes.

The length of the injection tube is 1 to 3 m, and a 10 glass tube of about 5 CIn is connected to the tip thereof, and the rubber stopper 9 is passed through this glass tube.

This rubber stopper 9 has a size that fits into a hole 13 drilled into the tree trunk or root, and the stopper seals the hole with the stopper to prevent leakage of the chemical solution 2 and intrusion of air.

In particular, as shown in FIG. 2, the bottom of the rubber stopper 9 is formed into a concave surface 11, and the tip 12 of the glass tube 10 penetrating there is structured so that it does not protrude into the concave surface. 13, and can prevent air from accumulating in the connection part during use.

A degassing hole 5 is provided in the lid of the chemical solution supply port 4 of the container to prevent internal pressure from building up during injection.

When using this device, make a hole as perpendicular to the tree as possible while pouring water into the hole, immediately insert the rubber stopper 9 so that there are no air bubbles inside, and then turn the container on its side and open the chemical solution supply port. 3 facing down, the injection tube 6 is filled with a medical solution and the air is completely removed, and then the tip thereof is connected to a glass tube 10 that penetrates a rubber stopper 9.

The container is placed one step higher and the drop is used to inject the chemical solution.

Since several injection tubes are connected, it is possible to inject into several places at the same time, and it is possible to inject continuously and automatically using a head without leaking the chemical solution or intruding air.
