Peanut film mulching hole-free seeding machine and seeding method

By designing a peanut mulching planter that eliminates the need for holes, and utilizing a liftable micro-heat needle and a segmented presser, the problem of manual film breaking required in traditional peanut mulching planters is solved. This enables natural emergence of peanut seedlings and efficient mulching, improving the emergence rate and mulching quality.

AI Technical Summary

Technical Problem

Traditional peanut mulching planters require manual breaking of the film to release the seedlings after mulching, which is labor-intensive and time-consuming. Furthermore, the soil covering method is not precise enough, resulting in unstable germination rates and affecting yield and quality.

Method used

Design a peanut mulching hole-free planter. The integrated frame is equipped with a furrow opener, a planter, a mulching device, a weakening point pre-positioning component, a contoured double-disc soil covering device, and a segmented compactor. Local weakening points are formed by lifting and lowering micro-thermal needles. Combined with zoned force control and multi-level contouring adjustment, peanut seedlings can naturally break through the mulch and emerge from the soil.

Benefits of technology

It enables hole-free sowing of peanut seedlings, reduces labor intensity, improves germination and survival rates, ensures consistency in mulching quality and operational efficiency, and is suitable for large-scale planting.

Abstract

The invention relates to the technical field of agricultural equipment, and discloses a peanut film mulching hole-free seeder which comprises an integrated frame, and a connecting frame is arranged at the front end of the integrated frame and used for being connected with a traction machine in a hanging mode; according to the device, a weakening point is accurately preset on a mulching film through a liftable micro hot needle, the traditional manual or mechanical hole breaking is replaced, a hole-free seeding mode of one hole and one point is realized, and the hole-free seeding efficiency is greatly improved. According to the method, the complex procedure of manual film breaking is avoided, the labor intensity is reduced, through the controllable design of the weakening points, it is ensured that peanut seedlings naturally break the mulching film, damage to roots is reduced, the emergence rate and the survival rate are increased, and meanwhile the problem of weed breeding or soil moisture loss caused by too large broken holes is effectively solved.
