Intelligent comprehensive crop weeding device and method

Abstract

The invention discloses an intelligent comprehensive crop weeding device and method. The intelligent comprehensive crop weeding device comprises a rack, a vision and intelligent electric control system, a depth and height adjusting device, a line space weeding device, a plant space weeding device and an intelligent pesticide spraying device. A three-point suspension mechanism located on the rack is connected with a walking machine. The vision and intelligent electric control system is used for acquiring relative position information of a plant and plant space weeding shovel and a nozzle and controlling the work states of the plant space weeding device and the intelligent pesticide spraying device. The depth and height adjusting device is used for adjusting the embedded depth of a line space weeding shovel and the plant space weeding shovel and the height of a chassis of the rack. The line space weeding device and the plant space weeding device are used for removing weeds of the line space of plants and weeds between the plants. The intelligent pesticide spraying device is used for removing the weeds which grow at the roots of the plants and can not be removed by the plant space weeding shovel. By the adoption of the intelligent comprehensive crop weeding device and method, the plants are protected against damage caused by the plant space weeding shovel, the problem that crop growth is impeded by the weeds growing at the roots of the plants is solved, and the weeds of the line space and the weeds between the plants of crops are comprehensively removed.

Description

technical field [0001] The invention relates to crop management machinery, in particular to an intelligent all-round weeding device for crops, which belongs to the field of agricultural machinery. Background technique [0002] The existence of weeds is the most common problem encountered during the growth of crops, especially the weeds at the roots of the plants, which directly compete with crops for water, nutrients and sunlight, seriously affecting the growth of crops. At present, weeding in the field mainly depends on chemical weeding, which leads to the widespread use of herbicides. Although remarkable results have been achieved, it has also brought many problems. The rough spraying method has caused a waste of energy, causing weed resistance and pesticide residues. security issues, etc. This requires a method that can replace large-scale application of pesticides for weeding. [0003] Aiming at the problem of herbicide abuse, there are researches on corresponding wee...

AI Technical Summary

Problems solved by technology

As the forward speed increases, the rate of injury to seedlings also increases, and the rate of injury to seedlings is within 8%. The number of weeding claws entering the inter-plant area is related to the planting spacing of crops. Crops planted within a plant spacing of 20cm cannot guarantee each inter-plant area. There are weeding claws to enter between the plants for weeding, so some of the plants cannot be weeded, especially the weeds at the root of the plants
