A wheat no-tillage seeder suitable for full straw-covered land 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 planter in agricultural machinery, in particular to a working machine suitable for planting wheat after harvesting of the previous crop of corn, rice, and cotton. Background technique [0002] In the corn-wheat, rice-wheat, and cotton-wheat rotation areas in my country, wheat needs to be planted in time after the harvest of the previous crops of corn, rice, and cotton. Due to the large amount of corn, rice, and cotton stalks left in the field after mechanized harvesting, the next crop of wheat is mechanized Planting brings greater difficulty, the main problems include the following: [0003] 1. After the previous crops are harvested, the amount of straw covered in the field is large, and the row spacing of wheat is narrow, usually about 15-20cm. During mechanized planting operations, the residual straw in the field can easily cause the planter opener to hang up the grass. [0004] 2. After corn, rice, and cotton are harvested, if no-t...

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 in the prior art. One is a traditional rotary tiller, that is, a tractor pulls a rotary tiller and a seeder. This method is widely used in Jiangsu. Before planting, it is necessary to manually clean up the straw or crush the straw and return it to the field, which is laborious, time-consuming and labor-intensive.

[0008] Another kind of machine is a multi-functional unit for crushing straw, clearing straw, fertilizing, sowing, and covering straw with the patent number 201220535075.6, and the announcement number is CN202941107U. Poor power, many faults, and a multi-functional unit that can cover the field ridges in time after fertilizing and sowing, straw cleaning, fertilization, sowing, and straw covering. This machine is not suitable for previous crops such as corn, rice, In the operation of sowing wheat after cotton is harvested, the last two problems of the above three defects still exist, and the sowing effect is not good

So far, there is no suitable agricultural machinery in this field at home and abroad that can deal with and solve the above problems in a targeted manner.
