AI Technical Summary
In fields with a lot of residual plastic film or dense weeds, traditional seeding equipment is prone to malfunction due to entanglement and blockage by the plastic film and weeds. This can prevent seeds from falling into the soil properly, resulting in problems such as missing seedlings, uneven plant spacing, and low germination rate.
The frame is equipped with a disc trencher. The disc trenching component is located in front of the trencher and includes a rotatable trenching disc and a scraper, forming a V-shaped structure for cutting and pushing away the mulch film and weeds. The trenching depth and soil penetration depth can be flexibly adjusted by adjusting the component.
It effectively cuts and separates plastic film from weeds, ensures smooth operation of the furrow opener, creates a clean planting furrow environment, improves the accuracy of sowing and the quality of operation, and adapts to different soil conditions and plastic film residue.
