Push-and-shift anti-drifting spray lance

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a push-and-shift anti-drifting spray lance. The push-and-shift anti-drifting spray lance comprises a main frame body, a drawing frame, a front cover plate, a back cover plate, a spray lance retainer, a seedling shifting rod, a spray lance and spray nozzles, wherein the drawing frame is connected to the front side of the main frame body; the lower end of the main frame body is connected with the spray lance retainer; the spray lance is mounted on the spray lance retainer; the spray nozzles are arranged on the spray lance; the lower end of the spray lance retainer is connected with the seedling shifting rod parallel to the spray lance; the upper end of the spray lance retainer is connected with the front cover plate located in the front of the lower part of the main frame body and the back cover plate located behind the lower part of the main frame body; the spray lance is located above the seedling shifting rod and between the front cover plate and the back cover plate. The push-and-shift anti-drifting spray lance can be used for effectively controlling damage of diseases and pests of field crops, can solve the problem of agricultural mist droplet drifting in machine tool operation, and is low in manufacturing cost and good in use and operation effect.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a push-and-pull anti-drift spray rod. Background technique [0002] The boom sprayer can quickly and effectively spray pesticides on field crops, but the diseases and insect pests of field crops often occur at the roots, and the dense canopy blocks the effective spraying of pesticide droplets, and the problem of pesticide droplet drift is also a problem. People are concerned that the lost pesticide droplets not only pose a threat to the health of the operators themselves, but also cause immeasurable harm to other non-target crops and the environment around the field. [0003] At present, the field spray anti-drift technology is mainly the wind curtain barrier type, that is, an air bag is added behind the spray boom. The air bag can not only blow open the crop canopy, so that the pesticide mist can be sprayed to the diseased area under the canopy, but also the air b...
