NOVEL DRUG SPRAY DEVICE FOR FOREST PROTECTION

摘要

Disclosed is a novel drug spray device for forest protection, mainly solving the problem that a large machine cannot enter where forest is on two sides of a road to spray pesticides, the machine also being large in volume, complex in structure and irrational in layout and having a high drug spray cost. One side of a drug tank (10) is provided with a first-level electric motor (13), a rotary shaft (12) is arranged inside the drug tank (10), stirring blades (11) are arranged on the rotary shaft (12), and the first-level electric motor (13) is connected to the rotary shaft (12). A lower pipeline (14) is arranged inside a base (3), an upper end of the base (3) is provided with an upper pipeline (16), an upper end portion of the upper pipeline (16) is provided with a shower head (18), and one end of the lower pipeline (14) is connected to the drug tank (10), and the other end thereof is connected to a lower end portion of the upper pipeline (16). One side of the upper pipeline (16) is provided with a hydraulic pump (20), an upper end of the hydraulic pump (20) is provided with a hydraulic rod (19), an upper end of the hydraulic rod (19) is connected to a connection point between the shower head (18) and the upper pipeline (16) via a snap ring (17), and the hydraulic pump (20) drives the upper pipeline (16) to move vertically via the snap ring (17) on the hydraulic rod (19). The device facilitates spraying drugs on trees at any height, and has a simple structure and a reduced drug spray cost.
