Bursaphelenchus xylophilus disease multi-micropore non-return quick suction needle type trunk pesticide injection device

Abstract

The invention belongs to the technical field of forestry pest control, and provides a pine wood nematode disease multi-micropore non-return quick suction needle type trunk pesticide injection device which comprises a liquid storage pipe, a piston assembly with a front rod, a limiting assembly matched with the piston assembly, a multifunctional valve set and a quick change needle head assembly. The multifunctional valve group comprises a valve body, an air escape valve, a first one-way valve and a second one-way valve, a first quick-change self-sealing adapter, a liquid storage tank adapter and a second quick-change self-sealing adapter are arranged on the multifunctional valve group, the quick-change needle head assembly comprises a non-return device and a needle head part, and the needle head part comprises a main needle tube and two elastic branch tubes. And a synchronous plug piece is arranged at the forked part of the needle head piece. The device is reasonable in design, good in portability, convenient to operate, high in injection capacity, capable of breaking through the time limit of punching pesticide injection, capable of achieving perennial normalization of pine tree trunk injection pesticide application, small in damage to pine tree bodies, high in treatment efficiency and utilization rate and suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of forestry disease and insect pest control, and relates to a trunk medicinal liquid injection device, in particular to a pine wood nematode disease multi-microporous non-return quick suction needle type trunk medicinal injection device. Background technique [0002] Pine wood nematode is a devastating epidemic of pine trees, and one of the most harmful and devastating diseases in the global forest ecosystem. It is extremely contagious and is known as the cancer of the pine tree. The pine wood nematode enters the xylem through the nutrient-supplemented wound of the pine brown longhorn beetle, and parasitizes in the resin canal. The pine wood nematode disease moves while multiplying, gradually spreads to the whole plant, and leads to the destruction and death of the parenchyma cells and epithelial cells of the resin canal, causing the plant to lose water, reduce transpiration, and sharply reduce and stop resi...
