Mechanical weeding mechanism with function of changing track to avoid seedlings

Abstract

The present invention aims to provide a mechanical weeding mechanism with the function of changing the track and avoiding the seedlings. The equipment includes a supported aluminum horizontal turntable, a module with the function of changing the track and avoiding the seedlings, and a loose cutting ruler mechanism. Power is provided by the motor to drive the aluminum horizontal turntable. On this basis, machine vision is used to collect and analyze the poses of field seedlings and grass, and the function of changing tracks and avoiding seedlings is realized through the multi-degree-of-freedom movement of the claw arm. This mechanism is helpful Improve the weeding effect, increase the rate of weeding between plants, reduce the rate of injury to seedlings, and ensure soil compactness.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural engineering and relates to a mechanical weeding mechanism with the function of changing tracks and avoiding seedlings. Background technique: [0002] The trochoidal track mechanical weeding mechanism uses its rod-shaped spring teeth to rotate horizontally, turning into the gap between seedlings to damage inter-plant weeds, and the end of the rotating rod-shaped spring teeth is inserted into the soil layer to disturb and comb the soil surface. As the weeding machine advances along the ridge, the rod-shaped spring teeth form a pendulum movement track, covering the soil layer, and realizing the removal of weeds in the area. The mechanical weeding mechanism is required to have good grass cutting performance and can scratch the stems and leaves of weeds. The rod-shaped elastic teeth follow the rotation of the horizontal disc. When moving along the ridge of the seedling belt, a trochoid track is ...

AI Technical Summary

Problems solved by technology

However, for traditional trochoidal mechanical weeding, the morphological parameters of the trochoidal trajectory formed on the soil surface are fixed, and it is difficult to cope with the characteristics of many types of weeds and regional growth; secondly, the removal rate of weeds close to crops is low, but The spring teeth are too close to the crops when they enter the gap between plants, causing serious damage to the seedlings, and the movement of the traditional spring teeth forms a plane trajectory. When moving to the ridge, the ends of the spring teeth will penetrate too deep into the soil, disturbing the soil layer. large, affecting the compactness of the soil, and the compactness of the soil after deep scratches decreases, which is not conducive to the exchange of material and energy between the plant root system and the soil; Forming a fixed tooth track shape, it is difficult to cope with the weeding needs of variable weed areas, and there are under-scratch and over-scratch situations
