AI Technical Summary

Technical Problem

Existing plant protection equipment requires workers to carry the sprayer when spraying pesticides on low-growing crops, which increases the labor burden and makes it difficult to achieve full mixing of multiple pesticides, resulting in pesticide damage and reduced efficacy.

Method used

Design a pesticide and fertilizer sprayer that includes a storage tank, a feeding mechanism, a mixing mechanism, and a spraying mechanism. The pesticides are mixed in proportion by the feeding mechanism, stirred by the mixing mechanism, and sprayed by the spraying mechanism, thereby reducing the labor intensity of workers.

Benefits of technology

This technology enables the mixing and spraying of multiple drugs in specific proportions, reducing the labor intensity of workers, improving drug efficacy, and reducing pesticide damage.

Abstract

The invention discloses a pesticide and chemical fertilizer sprayer for agricultural plant protection, and relates to the technical field of agricultural machinery. The storage box is arranged on one side in the box body; the feeding mechanism is arranged on one side of the interior of the box body and connected with the storage box. The stirring mechanism is arranged on the side, away from the feeding mechanism, of the partition plate. Connecting rods are screwed to the front side and the rear side of the upper surface of the fixing plate through hinge seats, moving blocks are screwed to the upper ends of the connecting rods through hinge seats, and the moving blocks are arranged in sliding grooves in the outer bottom wall of the box body in a sliding mode. The pushing lead screws are arranged in the fixing plate in a bilateral symmetry mode, the pushing lead screws are connected to the moving blocks on the two sides in a screwed mode through threads, and one end of one pushing lead screw is connected with a pushing motor; the spraying mechanism is arranged on the fixing plate, a pumping pump is fixed to one side wall of the fixing plate, and the pumping pump is connected with the box body through a telescopic pipe; according to the pesticide spraying device, various pesticides can enter the box body in proportion and then are mixed, the pesticides can be directly sprayed after being mixed, a worker does not need to bend down to spray the pesticides, and the burden of the worker is reduced.
