Trunk injection head holder

Abstract

A liquid injection head fixator for trunks is composed of a fixing plate 1, a butyl rubber stopper fixing groove 2, a liquid injection head socket 3, binding wire troughs 4 and a butyl rubber stopper 5. The liquid injection head socket 3 which is 6mm in diameter and capable of allowing liquid injection heads different in shape and size to insert is reserved in the middle of the fixing plate 1; the groove (namely the butyl rubber stopper fixing groove 2) which is 20mm in diameter and 1mm in depth is arranged in the bottom of the fixator, and the butyl rubber stopper 5 is fixed in the butyl rubber stopper fixing groove 2 so as not to displace; the butyl rubber stopper is a cylinder 20mm in diameter and 4mm in thickness, and a groove which is 4mm in diameter and 2mm in depth is arranged in the center, so that the injection heads conveniently penetrate the rubber stopper; the binding wire troughs 4 include the upper wire trough and the lower trough, so that the fixator can closely contact with the trunks in different parts of the same by using the wire troughs different in height.

Description

technical field [0001] The invention relates to a fixing device for a tree trunk liquid injection head, and is particularly suitable for fixing the injection head for tree trunk liquid injection in a hanging bag (bottle) manner. Used for tree pest control, tree nutrient solution supplementation, etc. Background technique [0002] The liquid injection heads of the hanging bag (bottle) type tree trunk liquid injection equipment currently used in the market are basically all of the expansion plug type (that is, the liquid injection head gradually becomes thicker from the head to the root or the method of stepwise thickening is used. plug the hole to prevent the liquid from flowing out). This type of liquid injection head is more convenient and quick to use, but since the expansion plug type liquid injection head needs to be closely combined with the outermost xylem of the liquid injection hole, this part of the xylem cannot transport the injection liquid. According to the rel...

AI Technical Summary

Problems solved by technology

This kind of liquid injection head is more convenient and fast to use, but because the expansion plug type liquid injection head needs to be closely combined with the outermost xylem of the liquid injection hole, this part of the xylem cannot transport the injection liquid

According to the relevant experiment of "Tree Pipeline Model Theory", this method will affect the conduction of the trees to the injected liquid, and then affect the effect of the injected liquid (such as the reduction of the control effect of diseases and insect pests, and the obstruction of tree nutrient transport).
