  • Agricultural planter and inter-furrow straw mulcher
    Patent number: 11160203
    Abstract: The invention relates to an agricultural seeding machine, in particular to a straw crushing and inter-furrow collecting-mulching no-tillage seeder. A straw-crushing device, a guide device, a fertilizer discharging device, and a furrowing and seeding device are sequentially arranged on a rack from front to back. According to the guide device, a plurality of straw-crushing guide assemblies having installation positions capable of being horizontally adjusted are arranged on an adjustment crossbeam, are in a prow shape, and each consist of a rear vertical back plate formed with a fertilization port, and two front symmetrical oblique guide plates. Straw is orderly spread on straw mulching belts between seeding belts while being crushed within the working range, and thus, the seeding belts are free of straw obstacles. The straw crushing and inter-furrow collecting-mulching no-tillage seeder is high in working integrity, easy to assemble, and low in energy consumption.
