Tillage-free sower

Abstract

The invention discloses a tillage-free sower. The tillage-free sower comprises a cross beam plate and is characterized in that a motor is fixedly installed at the front end of the cross beam plate, arotary shaft is connected to the lower end of the motor, a weed roll is arranged on the side wall of the rotary shaft, a cutting disc is arranged at the lower end of the weed roll, a coulter shelf isarranged at one side of the motor, a coulter is hinged to the lower surface of the coulter shelf, a connecting rod is arranged on the side wall of the coulter, a piston rod is hinged to the end of theconnecting rod, under the control of the piston rod, the connecting rod can adjust the tillage depth, a seed box is arranged at one side of the coulter shelf, idler wheels are arranged inside the seed box, a sowing pipeline is communicated with the lower end of the seed box, and a compacting shelf is hinged to the tail of the cross beam plate. The tillage-free sower is simple in structure, twinedweeds can be quickly removed, the sowing efficiency is improved, and the soil-breaking effect is good.

Description

technical field

[0001] The invention relates to the technical field of sowing operation tools, in particular to a no-tillage seeder. Background technique

[0002] In the vast northern dry farming areas of our country, the spring sowing season is mostly a period of low soil moisture content, that is, the soil moisture is poor, which is called nine spring droughts in ten years, which seriously affects agricultural production. In order to maintain the limited moisture in the soil, in recent years, no-tillage and less-tillage techniques have been promoted in agronomy, that is, before the spring sowing operation, the land with the original crop stubble will not be plowed, deep, and Harrowing, plowing and other operations, that is, to complete the sowing of corn, soybeans and other upland crops on the unplowed stubble land, because the stubble, stems and weeds of the crops of the previous season are all left on the soil surface and in the shallow soil layer , the land condition i...
