Wheat no-tillage seeding machine suitable for full straw mulched ground operation

Abstract

The invention relates to a wheat seeding machine in agricultural machinery, in particular to a wheat no-tillage seeding machine suitable for full straw mulched ground operation. A tractor power output shaft (16) is connected with a horizontal wide box type straw smashing clearing machine, a transverse shallow rotating mechanism (6) is arranged at the back, a first half part of a semicircular cover (6c) of the shallow rotating mechanism (6) is an arc-shaped cover plate, a rear half part of the semicircular cover (6c) is a grid cover formed by a plurality of arc-shaped strips, a wheat fertilizing seeding machine arranged at the back is of an integrated type, a front three-point suspension part (15) is adopted to be connected with a tractor (1), a rear three-point suspension part (13) is connected with the wheat fertilizing seeding machine, and depth limiting wheels (17) are respectively arranged on the left side and the right side of the straw smashing clearing machine. According to the wheat no-tillage seeding machine, straw smashing clearing, operation processes such as shallow rotation, fertilization, seeding, straw mulching after seeding can be finished in one time, times of the machine going to fields is reduced, the operation cost is reduced, and mechanical seeding of narrow line spacing crops such as wheat in corn and rice full straw mulched ground is achieved.

Description

technical field [0001] The invention relates to a seeder in agricultural machinery, in particular to an operating machine suitable for sowing wheat after harvesting previous crops of corn, rice and cotton. Background technique [0002] In my country's corn-wheat, rice-wheat, and cotton-wheat rotation areas, it is necessary to sow wheat in time after the previous crops of corn, rice, and cotton are harvested. Since there are a large amount of corn, rice, and cotton straw left in the field after mechanized harvesting, it is necessary for the next crop of wheat to be mechanized. Seeding brings greater difficulty, and the main problems include the following: [0003] 1. After the previous crops are harvested, the amount of straw covering the field is large, while the row spacing of wheat planting is narrow, usually about 15-20cm. During mechanized sowing operations, the remaining straw in the field can easily cause the ditch opener of the planter to be blocked by grass. [0004]...

AI Technical Summary

Problems solved by technology

[0003] 1. After the previous crops are harvested, the amount of straw covering the field is large, while the row spacing of wheat planting is narrow, usually about 15-20cm. During mechanized sowing operations, the remaining straw in the field can easily cause the ditch opener of the planter to be blocked by grass hanging

[0004] 2. After corn, rice, and cotton are harvested, if the wheat no-tillage sowing operation is directly carried out, the surface soil is compacted and the reflux is poor due to the lack of rotary tillage. Seed drying phenomenon

[0005] 3. Due to the ridge planting of corn and cotton or the crushing of harvesting machines, the fields of corn, rice and cotton are uneven after harvesting, and the phenomenon of dry seeds is easy to occur when the wheat no-tillage planter is operating.

It can be seen that the current mechanized sowing of corn, rice and cotton after harvesting wheat must first process the straw, and then perform rotary tillage and sowing operations. Time-consuming, high operating costs

[0007] There are two types of machines that are relatively similar
