A weeding device integrating cutting and spraying

Abstract

A weeding device integrating cutting and spraying belongs to the technical field of agricultural machinery. The invention consists of a spraying part, a cutting part, a connecting assembly, a bolt group I and a bolt group II, wherein the spraying part is provided with an electric push rod, and the cutting part consists of Composed of four sets of identical cutting components, the cutting connecting piece is fixed on the connecting component through the screw hole and through hole pair II, the stepping motor is fixed on the cutting connecting piece, the stepping motor meshes with the long shaft of the gear type, and the gear type The long axis and the profiling tool are fixed through the coupling, and the four sets of cutting parts are 90° to each other, the cutting parts and the spraying parts are 45° to each other, and the connecting assembly is composed of a short shaft and a disc; The combined use of cutting can not only remove weeds more efficiently, but also reduce the damage to the land and play a role in environmental protection; it can also be used in the growth period of corn crops, combined with circuit control to automatically avoid plants and remove the plants at the same time Weeds between and between rows, the present invention has simple structure and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a weeding device integrating cutting and spraying. Background technique [0002] During the growth of corn plants, the growth of weeds is always accompanied. Under the same nutrient conditions, corn plants and weeds are in a state of competition. Corn plays a pivotal role in ensuring grain production, and weeds in cornfields are one of the main factors affecting corn production. At present, there are spraying and mechanical weeding methods for weeding. The extensive spraying is not only easy to damage the plants, but also damages the soil structure and nutrients. The mechanical weeding also has defects, and it is not easy to remove the inter-row and inter-plant weeds at the same time. Weeds, weeding rate is not high and other problems. Through recent research, it is found that spraying the cut weeds only needs 1 / 7 of the original spraying amount to re...
