Active paddy field weeding device with self-adaptive weeding strength

Abstract

The invention relates to an active paddy field weeding device with self-adaptive weeding strength. The active paddy field weeding device comprises an inter-row weeding component and a driving component, wherein the inter-row weeding component comprises a rigid inter-row weeding roller group and a plurality of flexible inter-row weeding roller groups; the rigid inter-row weeding roller group is vertically arranged; the flexible inter-row weeding roller groups are evenly distributed around the circumference of the rigid inter-row weeding roller group; the driving component drives the inter-row weeding component to rotate, so that the rigid inter-row weeding roller group carries out autoroatation; and the flexible inter-row weeding roller groups carry out circumferential rotation around the autoroatation center of the rigid inter-row weeding roller group. The active paddy field weeding device adopts a weeding scheme that rigid weeding roller fingers and flexible weeding roller fingers are matched for weeding and meanwhile, a sensing mechanism is used for conducting active strength adjustment, and the active paddy field weeding device belongs to the field of mechanical weeding.

Description

technical field [0001] The invention relates to the field of mechanical weeding, in particular to an active paddy field weeding device with self-adaptive weeding intensity. Background technique [0002] In the rice field ecosystem, weeds compete with rice for growth space, fertilizer nutrients, light, heat and other resources, which is one of the important reasons for the decline in rice yield and quality. Effective control of weed growth is an important part of rice growth. links. Although the use of chemical herbicides can efficiently and timely control weed seedlings and avoid affecting the yield after weeds mature, the residual toxicity of chemical agents will cause certain environmental pollution to crops and soil. Therefore, mechanical weeding methods have begun to receive more and more attention in recent years. [0003] There are still problems in paddy field mechanical weeding.

AI Technical Summary

Problems solved by technology

[0003] There are still problems in paddy field mechanical weeding. The traditional inter-row weeding components mainly realize inter-row weed control through pressing, cutting, and pulling. Most of them are passive and have limited weeding intensity. In areas with high weed density, due to The root system of the colony and the soil are intertwined with each other, forming a network-reinforced soil-fixing pattern, resulting in poor weed control effects in high-density areas

[0004] The inter-row weeds are disturbed by the row of rice, and it is difficult for the weeding parts to avoid the rice plants to effectively control the inter-row weeds. However, the existing relatively mature inter-row weeding parts need to be strictly aligned during operation, otherwise the weeding parts may invade the rice. Damage to the root zone of the rice plant, or may be far away from the root zone of the rice plant, making it difficult to effectively control weeds in the root zone

However, the flight path of paddy field operation equipment is unstable, and the curvature of the seedling belt changes, making it difficult to guarantee the parallel operation in the paddy field environment.
