An intelligent all-round weeding device and method for crops

Abstract

The invention discloses an intelligent all-round weeding device and method for crops, comprising a frame, a visual and intelligent electric control system, a depth and height adjustment device, an inter-row weeding device, an inter-row weeding device, and an intelligent spraying device. The three-point suspension mechanism located on the frame is connected with the walking machinery; the vision and intelligent electronic control system is used to collect the relative position information of the plants and inter-plant weeding shovels and sprinklers, and control the working status of the inter-plant weeding device and the intelligent spraying device; The depth and height adjustment device is used to adjust the depth of the inter-row weeding shovel and the inter-row weeding shovel and the height of the frame chassis; the inter-row weeding device and the inter-row weeding device are used to remove weeds between the rows and between the plants; intelligent spraying The medicine device is used to remove the weeds at the roots of the plants that cannot be removed by the weeding shovel between the plants. The invention protects the plants from being damaged by the weeding shovel between the plants, solves the problem that the weeds at the root of the plants hinder the growth of the crops, and realizes the all-round removal of the weeds between the rows of the crops and between the plants.

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 weed...

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
