Combined passive soil stirring device of no-tillage planter

Abstract

The invention discloses a combined passive soil stirring device of a no-tillage planter. The combined passive soil stirring device comprises a primary structural rack, a subsoiler assembly, a profiling body and a rake flatting shovel; the profiling body comprises a mount with a square through hole, a square supporting vertical-bar, four elastic triangular rods and a connecting rod, wherein the cross section of each elastic triangular do is in the shape of an isosceles right triangle, the four elastic triangular rods surround to form a box with a square hole, and then penetrate the square through hole in the mount, bevels of the elastic triangular rods closely fit corresponding surfaces of the square supporting vertical-bar, and two right-angle surfaces of each elastic triangular rods closely fit the wall faces of the square through hole. The profiling of the rake flatting shovel is realized through the elastic triangular rods, and accordingly surface soil depth difference of concave areas can be reduced, adaptability of the combined passive soil stirring device of the no-tillage planter to uneven earth surface in tillage can be improved, and secondary damage to the even surface from the rake flatting shovel after stirring can be reduced.

Description

technical field [0001] The invention belongs to the technical field of farmland seeders in agricultural machinery, and in particular relates to a combined passive soil disturbance device for no-tillage seeders. Background technique [0002] With the transfer of land in our country, the area of ​​individual cultivation of fields increases, and the rise of agricultural machinery cooperatives, there is an urgent demand for wide-width, high-efficiency, high-speed oil-wheat dual-purpose seeders. In the wide-width sowing operation of the oil-wheat dual-purpose no-tillage seeder, no-tillage is used for sowing, and the seeder is not equipped with a rotary tillage device. It is difficult to eliminate the soil depression caused by the compaction of the loose soil by the tires of the high-powered tractor, resulting in ditching in the soil depression area. The shovel and fertilization ditching shovel cannot effectively touch the soil. The depth of sowing and fertilization in the soil de...

Problems solved by technology

In the wide-width sowing operation of the oil-wheat dual-purpose no-tillage seeder, no-tillage is used for sowing, and the seeder is not equipped with a rotary tillage device. It is difficult to eliminate the soil depression caused by the compaction of the loose soil by the tires of the high-powered tractor, resulting in ditching in the soil depression area. The shovel and fertilization ditching shovel cannot effectively touch the soil, the depth of sowing and fertilization in the soil depression area is difficult to reach the predetermined depth, and the seeds and fertilizer are exposed on the ground surface, which reduces the consistency of sowing depth and fertilization depth, and it is difficult to ensure a good emergence effect
