Coaxial push-in-type tree injection tool

Abstract

The invention discloses a coaxial push-in-type tree injection tool. The tool is characterized by comprising a syringe needle, a core rod and a conversion connecting portion, wherein a flow pass extending towards the front end is arranged inside the syringe needle, a connector is arranged at the rear end of the syringe needle and connected with the conversion connecting portion, and the conversion connecting portion is provided with a hose connector; a conical end is arranged at the front end of the core rod, the diameter of the conical bottom of the conical end is equal to the outer diameter of the front end of the syringe needle, the rear end of the core rod penetrates through the flow pass, the connector and the conversion connecting portion, and the rear end of the core rod outside the conversion connecting portion is connected with a pressing plate; when the conical end is flush with the front end of the syringe needle, a distance is maintained between the pressing plate and the conversion connecting portion, and the portions, inside the flow pass and the conversion connecting portion, of the core rod are provided with longitudinal grooves. Tree trunk tissue fiber will not be cut off, later wound healing and growth are facilitated, a needle hole will not be blocked, the infusion coverage diffusion area can also be increased, uniform distribution and transportation of liquid medicine or a nutrient solution are facilitated, and fast absorption is facilitated.

Description

technical field [0001] The invention relates to a device for infusion in the field of tree and plant protection, in particular to a coaxial push-in type tree injection device. Background technique [0002] Our country is a large forestry country, and fruit trees are widely planted. With the improvement of planting technology, when the seedlings are transplanted or in their critical growth period or when diseases occur, in order to make the trees grow healthily, it is often necessary to infuse them to provide them with the necessary water, nutrients or Drugs, thereby greatly improving the survival rate and growth trend of trees, have obvious effects on increasing production and increasing efficiency, especially the cultivation of some trees with high economic value is inseparable from infusion maintenance, so infusion technology is especially important. The existing tree infusion is also like human infusion. The nutrient solution or medicinal liquid is input into the trunk th...

AI Technical Summary

Problems solved by technology

The existing tree infusion is also like human infusion. The nutrient solution or medicinal liquid is input into the trunk through the needle inserted into the trunk, and then transported from the tissue in the trunk to the crown, which is conducive to the rapid absorption of the tree. Although the existing tree infusion methods are already very common , but its infusion equipment does still use equipment similar to human or animal infusion, such as bagged nutrient solution, dropper and injection head. The needle is easil...
