Weeding device between paddy fields

Abstract

The invention relates to the field of agricultural mechanical engineering. The purpose is to provide an active access type paddy field inter-row weeding device, which can effectively cover the inter-row weeding area, improve the weeding effect, reduce the rate of weeding injury, and has a simple structure, stable operation, and high reliability. features. The technical solution is: a weeding device between paddy fields, which is characterized in that it includes a frame, two swing rod hinge brackets fixed on the left and right sides of the frame, respectively hinged on the two swing rod hinge brackets and can be vertically Two pendulum bars that swing in a straight plane, a driving mechanism that is installed on the frame and exerts force on the two pendulum bars to drive the two pendulum bars to approach or separate from each other, and two weeding rods that are respectively fixed at the lower ends of the two pendulum bars Knife, a camera installed on the frame to collect images of paddy fields in real time, and a controller to control the weeding movement between the weeding knives.

Description

technical field [0001] The invention relates to the field of agricultural machinery engineering, in particular to a weeding device between paddy fields. Background technique [0002] Rice is the largest grain crop in China. In the process of rice production, weeds in paddy fields compete with rice for growth resources, which is one of the main reasons for the decline of rice yield and quality. Mechanical weeding is an environmentally friendly weeding method that uses special equipment to remove weeds in the field. It meets the needs of green production and life and is worthy of vigorous promotion. [0003] The existing machines for weeding can be divided into row weeding machines and inter-row weeding machines according to the area covered by the weeding operation. At present, the application of weeding machinery between rows of paddy fields is relatively mature. However, due to the passive entry type, there are problems such as small coverage of the weeding area between r...

AI Technical Summary

Problems solved by technology

At present, the application of inter-row weeding machinery in paddy fields is relatively mature, and the inter-row weeding machinery has the problems of small coverage of inter-row weeding area and low weeding efficiency due to the passive entry type, and its practical application needs to be improved, especially the sensors and sensors. The inter-row weeder realized by the combination of machinery has the problem of complex drive control, and the deviation between mechanical operation and computer simulation is prone to occur, resulting in low weeding reliability and high seedling damage rate.
