The invention relates to the field of agricultural machinery and discloses a machine vision based weeding device between plants. The weeding device consists of a body, blocks, a guide rail, opening-closing arms and tail end actuators; the device adopts a standard three-point mounted manner, so that the device can be hooked on different work platforms and is strong in adaptability; machine vision performs identification on a seedling belt so as to control the device to move on the guide rail, therefore, the work position of the device is above the seedling belt all the time, and precise workingunder different environments and different vehicle platforms can be realized; and machine vision also performs precise removing after identifying seedling grass, so that operation efficiency and quality can be greatly enhanced. The device can walk in fields with the vehicle platform during working, and controls a rack motor to control the opening-closing arms to descend after identifying weeds; tooth cutters of the tail end actuators rotate 360 degrees after staggered, so that the weeds can be uprooted and torn; and therefore, the device is excellent in weeding quality, and the re-growing ofthe weeds can be greatly inhibited.
Description
technical field [0001] The invention discloses an inter-row weeding device based on machine vision, relates to the field of agricultural machinery, and is specifically applied to intelligent inter-row weeding of various crops in the agricultural field. Background technique [0002] Farmland weeds are an integral part of the agricultural ecosystem, which directly or indirectly affect agricultural production. Weeds in the field compete with crops for water and nutrients. Many weeds have deep roots and lush leaves, especially in dry areas. Weeds often absorb more water than crops. Weeds occupy farmland space and affect photosynthesis of crops. , and interfere with crop growth, greatly reduce the yield and quality of crops, and indirectly promote the breeding and spread of pests and diseases. According to statistics, the area of weed damage in our country is huge, and the reduced output of a single crop can reach hundreds of millions of kilograms. It can be seen that the gro...
