Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural plant protection equipment, in particular to a hand injection trunk pesticide applicator. BACKGROUND

[0002] At present, most of the tree pesticide or fertilizer application is carried out by base application, root irrigation and foliar spraying. These methods have slow absorption by crops, most of the fertilizer is not absorbed by trees, a large amount of fertilizer is lost, and the evaporation amount is large during spraying, causing certain waste. When carrying out tree insect control and disease prevention, the pesticide is usually sprayed directly to the leaves of the tree. During the operation, due to the evaporation of the surrounding environment and air, a considerable amount of pesticide is not sprayed on the leaves or the trunk, but is dispersed in the air, so the effect of controlling the borer is not good. Trunk injection pesticide application is a method of directly injecting pesticide into the trunk, which has the advantages of good control effect, high utilization rate of pesticide, and small environmental pollution. However, the existing trunk injection pesticide applicator has the problems of complex operation, uneven pesticide application, and waste of pesticide. CONTENT OF THE UTILITY MODEL

[0012] 2. The operator stabs the needle on the injection tube into the tree trunk to be medicated, and then manually pushes the piston rod. The liquid medicine in the injection tube is injected into the inside of the tree trunk through the needle. During the medication process, the operator can judge whether the liquid medicine has been injected into the inside of the tree trunk by observing the pressure gauge. After the medication is completed, the injection tube is pulled out, and a medication operation is completed. BRIEF DESCRIPTION OF DRAWINGS
