AI Technical Summary

Technical Problem

Existing weeding devices cannot completely destroy weed roots, leading to rapid weed regeneration, increased weeding frequency and probability of crop damage. At the same time, stripping the soil around crop roots reduces their supporting capacity and affects crop yield.

Method used

Design a smart weeding robot for soybean-corn intercropping. It employs multiple weeding methods, combined with a soil-raising mechanism to collect and crush weeds and soil, and deliver them to the area around the crop roots. The weed debris provides nutrients to the crop, while the spacing control component adapts to different plant spacing requirements, reducing weeding damage.

Benefits of technology

It achieves thorough weed control, reduces weeding frequency, minimizes crop damage, enhances crop root support and lodging resistance, improves soil structure, and saves on labor fertilization costs.

Abstract

The application discloses a soybean-corn compound planting intelligent weeding robot, and relates to the technical field of agricultural robots. The traction increasing mechanism can be used for synchronously adjusting the intervals of the multiple weeding mechanisms by the interval regulation assembly, so that the intervals of the multiple weeding mechanisms can be flexibly adjusted under different planting plant intervals of corn and soybean, the rapid weeding operation under the compound planting mode is improved, and the weeding efficiency is improved. The cultivation mechanism can collect, cut and stir the weeds and part of the soil which are dug by the weeding mechanism. The cutting process can damage the rhizome part of the weeds, so that the weeds lose the regenerative ability, the weeds after being dug are prevented from regenerating under suitable conditions, and the effect of completely weeding is achieved. The stirring process can mix the cut weeds and the soil, the weeds can be decomposed by the microorganisms in the soil after being mixed in the soil, so that the abandoned weeds can form nutrient substances which are beneficial to the growth of soybean and corn.
