Pesticide spraying apparatus with adjustable spraying range

Abstract

The invention discloses a pesticide spraying apparatus with adjustable spraying range in the technical field of agricultural production. The pesticide spraying apparatus comprises a guide rail, a liquid storage tank and a spraying mechanism. In the invention, spray heads of a first spraying component are adjusted in diagonal arrangement from up to down, corresponding to an oblique planting frame by an adjusting component based on an oblique angle of the planting frame on both sides of the guide rail, so that spraying range of the spray heads can be adjusted according to different planting frames; the liquid storage tank and the spraying mechanism move along the guide rail for long-distance pesticide spraying; after a connection assembly moves along a large-diameter tube, a threaded shaft rotates to tightly press the inner end of the threaded shaft against a rubber pad and the outer lateral wall of the large-diameter tube for being fixed on the large-diameter tube and separated from a connection shaft by placing a rotating rod through a limit plate on the threaded shaft; when the large-diameter tube moves, a press table on a second nozzle is in contact with the inner wall of the large-diameter tube through two sealing rings, thereby improving sealing performance, and a baffle is in detachable connection with ends of the large-diameter tube.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a pesticide spraying device with an adjustable spraying range. Background technique [0002] Pesticides, the current unified English name in the world is pesticide--that is, "killing chemicals", but in fact the so-called pesticides refer to harmful organisms (pests, pest mites, nematodes, pathogenic bacteria, miscellaneous insects, etc.) Grass and mice. Later, through the long-term development of production and living processes, we gradually realized that some natural chemicals and biological drugs that have the ability to prevent and control harmful organisms in agriculture and animal husbandry (to 17 categories, etc.) and regulate plant growth. Usually, various additives used for sanitation and improving the physical and chemical properties of active ingredients are also included. [0003] The broad definition of pesticides refers to chemicals used to prevent, ...

AI Technical Summary

Problems solved by technology

[0008] The existing large-scale planting mostly adopts greenhouse planting and other methods. In order to make reasonable use of space, etc., planting frames are often set up in the greenhouses for planting. Vegetables are distributed in steps. When liquids such as pesticides are sprayed horizontally, the pesticides are usually sprayed by laying pipelines and setting nozzles at fixed points. When the greenhouse is large, long-distance pipeline laying is required. When the pipeline system fails When spraying with a fixed-point sprinkler, the spraying range remains unchanged in order to spray evenly. When the distance between the planting racks changes or the inclination angle changes, the spraying range cannot be adjusted. convenient
