Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in the prior art, after the rice is harvested, there will be straw on the ground, and the ditch opener of the seeder will hang grass and be congested during the advancing process; and the soil moisture content of the rice stubble is high, and the soil is heavy , Poor fluidity, unreliable covering soil after sowing in furrows (especially poor soil fluidity on both sides of the ditch, soil suppression wheel cannot reliably push the soil on both sides into the ditch), resulting in the seed ditch cannot be closed, the seeds are exposed and cannot be covered by soil , resulting in a decrease in the emergence rate and affecting the quality of sowing

Abstract

The invention relates to a stubble cutting, ditching and earthing device for a no-tillage planter of rice stubble. A stubble cutting assembly comprises a stubble cutting disk component, wherein the disk component is provided with a sharp blade so as to cut joints in land during rotation and cut off straw and weeds on the ground surface; a ditch side scarification component comprises a pair of ditch side scarification disk parts which is inwards inclined from top to bottom, and is symmetrical on two sides by taking the stubble cutting disk component as the center; the ditch side scarification disk parts correspond to ditch side soil in position and are used for cutting the ditch side soil during rotation; a soil shifting component comprises a pair of soil shifting wheels which is inwards inclined from front to back, and is symmetrical on two sides by taking the stubble cutting disk component as the center; the soil shifting wheels are in windmill shapes; shifting surfaces of shifting claws to soil are in smooth curved shapes; the soil shifting wheels are driven by external power to rotate. The stubble cutting, ditching and earthing device disclosed by the invention is mainly characterized in that by matching front stubble cutting disks with two rear obliquely-arranged ditch side scarification disks and the followed soil shifting component, the passing ability of a machine tool and the quality of operation are better guaranteed.

Description

technical field [0001] The invention relates to a seeder auxiliary device, in particular to a device for breaking stubble, ditching and soil covering of a rice stubble no-tillage seeder, and belongs to the technical field of seeder auxiliary devices. Background technique [0002] Rice stubble no-tillage sowing wheat does not damage the soil structure, is conducive to soil moisture conservation, and can save investment in machine tillage, which is a better planting method. [0003] However, in the prior art, after the rice is harvested, there will be straw on the ground, and the ditch opener of the planter will hang grass and block up during the advancement process; The back cover soil is unreliable (especially the soil fluidity on both sides of the ditch is poor, and the cover soil suppression wheel cannot reliably push the soil on both sides into the ditch), resulting in the inability to close the seed ditch, and the seeds are exposed and cannot be covered by the soil, resu...
