Opening-closing type intelligent weeding device for acquiring seedling and grass information based on binocular vision

Abstract

The invention belongs to the technical field of agricultural equipment, in particular to an opening-closing type intelligent weeding device for acquiring seedling and grass information based on binocular vision. The device is fixedly connected to a horizontally arranged cross beam which is perpendicular to the heading direction. The weeding device comprises a binocular vision servo control system,an inter-strain grass removing end executor and a parallel four-rod profile modeling unit. The binocular vision servo control system comprises a binocular camera, a single chip microcomputer and a servo controller. The binocular camera is fixed on the front end face of the cross beam and used for acquiring seedling and grass information of a big field. The single chip microcomputer has an image processing function. The parallel four-rod profile modeling unit comprises a parallel four-rod mechanism, a land wheel rod and a land wheel. The parallel four-rod mechanism comprises an upper pull rod,a lower pull rod, a front installation plate, a back installation plate, a hanging rod and a hook. The inter-strain grass removing end executor comprises a top plate, a base plate, a hydraulic cylinder, a hoe rod and a hoe. According to the invention, the weeding device is compact in structure, high in weeding efficiency, high in accuracy, high in transportability, widely applicable and suitablefor various kinds of large-field working conditions.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and relates to an opening-and-closing intelligent weeding device for acquiring seedling grass information based on binocular vision. Background technique [0002] Elimination of field weeds is an important part of field management operations. At present, in our country, there are many methods of weeding, and the commonly used weeding methods include artificial weeding, chemical weeding and mechanical weeding. Manual weeding has the disadvantages of high labor intensity, time-consuming and laborious work, and low operating efficiency. Chemical herbicides are highly efficient, but if used improperly, not only will not achieve the expected control effect, but it will damage or even destroy crops, and the residual toxicity of the chemical will cause certain environmental pollution, which is not conducive to the sustainable development of agriculture. Mechanical weeding is more advanc...

AI Technical Summary

Problems solved by technology

At present, domestic mainstream mechanical weeding mostly uses a rotary hydraulic motor to drive the end actuator to perform swing or rotation operations, and uses single-camera machine vision to obtain the position information of seedlings and grass. The structure and function are relatively simple, and the control method is relatively complicated, requiring high accuracy
