Deeply digging, cultivating and seeding unit

Abstract

The invention relates to a deeply digging, cultivating and seeding unit which is mainly comprises a stand 1, a rotary cultivator 2, a deeply digging shovel 3, a fertilizing machine 4, a seeding machine 5, a compacting machine 6, a machine 19 for returning straws to the field, and the like, wherein the machine 19 for returning the straws to the field is directly installed on the stand and is positioned in front of the rotary cultivator 2; the rotary cultivator 2 mainly comprises a speed changing box 7, a rotary blade shaft 8, rotary blades 9 and the like which are installed at the lower part of the stand 1; the deeply digging shovel 3 is fixed on the beam of the stand through a U-shaped bolt, is installed at the front part or the back part of the rotary blade shaft, and passes through the gap between two adjacent rotary vades of the rotary cultivator 2; the fertilizer box of the fertilizing machine 4 and the seed box of the seeding machine 5 are fixed above the stand 1; the fertilizing machine and the seeding machine are installed at the back part of the deeply digging shovel 3; and the compacting machine 6 is installed at the back part of the whole unit.

Description

technical field [0001] The invention relates to a plowing and sowing unit, in particular to a compound subsoiling plowing and sowing unit. Background technique [0002] At present, the depth of cultivation of the soil by rotary seeders and no-tillage seeders in the society is relatively shallow, only about 15 cm. After years of repeated cultivation, the bottom half of the soil will form a hard layer, which is not conducive to Conservation of moisture and fertilizer, resulting in loss of water, soil, and fertilizer, and seriously affecting the growth of crop root systems. In addition, because there is no plowing operation before plowing, the stalks and weeds of the crops of the previous season are all on the surface, which is easy to cause entanglement and blockage during plowing. Contents of the invention [0003] The purpose of the present invention is exactly in order to overcome above deficiency, provides a kind of subsoiling plowing and sowing unit, and it mainly is m...

AI Technical Summary

Problems solved by technology

[0004] Positive effects of the present invention: the plowing depth of the subsoiling plowing and sowing unit of the present invention can reach about 30 cm, which not only solves the problem of repeated plowing by rotary sowers and no-tillage seeders in the current society all the year round, and the bottom half of the soil forms a hard bottom. Layer problem, more conducive to moisture conservation, fertilizer conservation and the growth of crop roots

And because the subsoiling knife passes through the gap between two adjacent rotary tillers of the rotary tiller, under the joint action of the subsoiling knife and the rotary tiller during tillage, the diameter bars and weeds of the crops on the surface are easily destroyed. Shredding solves the problem of winding and clogging of rotary seeders and no-tillage seeders in the current society, and is more suitable for the current market demand for energy saving, environmental protection, and protective farming, as well as the direction of social and technological development.
