Weeding device and weeding method

Abstract

The invention discloses a weeding device and a weeding method, which belong to the technical field of mechanical weeding. The weeding device includes a connection assembly, a global camera module, a local camera module, a main control system and multiple groups of weeding mechanisms; the global camera module is located at The distribution images of target economic crops and weeds are captured in the first area on the side of the direction of travel of the weeding device, and the local camera module captures images of green distribution in the second area on the side of the direction of travel of the weeding device; The distribution image of the weeds is used to obtain the distribution information of the target economic crops, and the weed distribution information is obtained according to the green distribution image and the distribution information of the target economic crops, and the action of the lifting drive and the weeding component is controlled according to the weed distribution information, so that the weeding component removes the weeds. Grass. The invention is used for mechanical weeding in the field, and can have higher weeding efficiency and better weeding effect on the basis of protecting the farmland environment and maintaining the growth of target economic 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
