Trunk injector capable of automatically adjusting dosage along with metabolic rate of tree

Abstract

The invention discloses a trunk injector capable of automatically adjusting the dosage along with the metabolic rate of a tree, and belongs to a liquid medicament applicator for forest trees. The trunk injector comprises a medicament chamber over which a liquid storage bag is arranged; the liquid storage bag is connected with the medicament chamber through an infusion tube and an air inlet tube; the mouth of the air inlet tube is higher than an injection port and the mouth of the infusion tube; the liquid storage bag is provided with a spare air inlet pipe; and the medicament chamber is a semi-cylinder or a semi-cone made of stainless steel or galvanized iron sheet and is provided with a chamber cover. The trunk injector can provide corresponding control or nutrient according to physiology of trees; and when diseases are serious or the trees require nutrient, the spare air inlet pipe can be adopted for injection timely. The trunk injector has the advantages of low cost, simple operation, and easy use in rural areas. The trunk injector achieves good effect in experiments in the control of bark beetle in Wushan County and the urban afforestation trees in Chongqing City.

Description

technical field [0001] The invention belongs to a forest liquid spraying device. Background technique [0002] In the practice of forestry stem borer pest control and large tree transplanting, systemic pesticides and nutrient solutions are often injected into the trunk, and injection tools are very important. The previous tree trunk injection machines cannot automatically adjust and control the dosage of systemic pesticides and nutrient solutions, and require quantitative plunger pressure pumps, pressure gauges, high-pressure hoses and other mechanical components with an injection pressure above 30Mpa, which are expensive. In order to change this situation, "automatic tree trunk injector" (Chinese Utility Model Patent Application No. 922384118) proposes a convenient portable tree trunk injection tool, which includes a liquid storage bottle with lifting lugs at the bottom, and a discharge bottle is inserted in the bottle mouth. The needle; the liquid discharge needle is comp...

AI Technical Summary

Problems solved by technology

But this injector is the same as the trunk injection machine of other structures, on the one hand, the size of the injection dose is outside the physiological cycle of tree metabolism, although the medicine is directly injected into the tree, it cannot be well absorbed; on the other hand, simple mechanical injection The method prevents the medicine from entering the tree body and is lost in vain, resulting in waste

Therefore, not only can not achieve the purpose of preventing and treating diseases and replenishing nutrients and water, but also has low efficiency and consumes chemicals and manpower.
