Weeding device and weeding method

Abstract

The invention discloses a weeding device and a weeding method, and belongs to the technical field of mechanical weeding. The weeding device comprises a connecting assembly, a global camera module, a local camera module, a main control system and a plurality of groups of weeding mechanisms; the global camera module shoots distribution images of target commercial crops and weeds in a first area located on the advancing direction side of the weeding device, and the local camera module shoots green distribution images in a second area located on the advancing direction side of the weeding device; the main control system obtains target commercial crop distribution information according to the distribution images of target commercial crops and weeds, obtains weed distribution information according to the green distribution image and the target commercial crop distribution information, and controls lifting driving parts and weeding assemblies to act according to the weed distribution information, so that the weeding assemblies remove weeds. The weeding device is used for field mechanical weeding, and has higher weeding efficiency and better weeding effect on the basis of protecting the farmland environment and maintaining the growth of target commercial crops.

Description

technical field [0001] The invention relates to the technical field of mechanical weeding, in particular to a weeding device and a weeding method. Background technique [0002] The planting of target economic crops can bring significant economic benefits to farmers. The planting areas are distributed in many provinces and autonomous regions in my country. The planting of target economic crops in farmland in my country generally adopts crop rotation. The different types and cultivation methods of previous crops lead to great differences in the occurrence of field weeds when the target economic crops are planted. At the same time, chemical herbicides are used to remove weeds in the field all the year round, and the population structure of weeds in the field of target economic crops has changed greatly. There are many kinds of weeds, and the growth time and occurrence characteristics of weeds also show great differences. . [0003] The overgrowth of weeds in the field will ha...

AI Technical Summary

Problems solved by technology

[0003] The overgrowth of weeds in the field will have a great negative impact on the growth and development of the target economic crops at the seedling stage. The conventional weeding method is generally to use herbicides. Although the use of herbicides can bring better results, but due to the After sowing and at the seedling stage, the distribution area of ​​weeds in the field is small, and the distribution uniformity in the field is low. It is easy to cause excessive application of chemical herbicides, which will not only cause damage to the farmland and water environment, but also increase the risk of pesticide residues. risk; and, long-term excessive application of herbicides will also destroy the balance of the farmland environment, resulting in the increase of weed resistance, making the effect of weeding gradually worse
