Problems solved by technology

The existing weeding machines used for large-scale farmland operations have a low weeding rate because the hoe blade is easily damaged; and due to the lack of a local fine-tuning mechanism for the hoe blade, it is inconvenient to set the blade, and the distance between the hoe blade and the crop seedlings cannot be adjusted correctly. High rate of injury to crops

Abstract

The invention discloses an inter-seedling weeding device and method, and relates to the technical field of agricultural machinery. The inter-seedling weeding device comprises a ground contour following device, a hoe blade lifting device, a tool setting device and a hoe blade device; and the ground contour following device comprises a contour wheel, a sliding plate, two sliding blocks, a spring and a cylindrical slide rail. The contour wheel and the hoe blade device are fixedly arranged on the sliding plate; and the sliding blocks are fixedly arranged on the sliding plate, and the sliding blocks and the spring are sleeved outside the cylindrical slide rail. The hoe blade lifting device comprises a second parallelogram mechanism and a second hydraulic cylinder, and the second hydraulic cylinder is arranged at the opposite sides or the adjacent sides of the second parallelogram mechanism. The tool setting device comprises a first parallelogram mechanism and a first hydraulic cylinder; and the first hydraulic cylinder is arranged on the opposite sides or the adjacent sides of the first parallelogram mechanism. According to the inter-seedling weeding device and method, disclosed by theinvention, the hoe blade can be protected and the seedling injuring rate during weeding can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an inter-seedling weeding device and a weeding method for removing weeds among crop seedlings. Background technique [0002] At present, most of the weeding methods in farmland are manual weeding or weeding by chemical methods. Manual weeding is a heavy workload and low efficiency; weeding by chemical methods usually has serious adverse effects on the ecological environment, food safety of agricultural products, and human health. Because mechanical weeding can greatly improve work efficiency while abandoning many hazards of chemical weeding, it has begun to receive more and more attention. [0003] Mechanical weeding is generally suitable for crops grown in rows in large fields, such as corn, cabbage, and lettuce. Weeds can be divided into row weeds and seedling weeds according to the location where they grow in the farmland. Weeds between rows refer to weeds th...
