Description

A no-tillage wheat planter with adjustable straw coverage

technical field

The utility model relates to a seeder in agricultural machinery, in particular to an improved mechanism of an operation machine suitable for no-tillage sowing of wheat after harvesting corn, rice and cotton crops. the

Background technique

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. Sowing brings greater difficulty. the

Patent No. 201210397462.2 "A Multifunctional Unit for Shredded Straw, Straw Clearing, Fertilization, Sowing, and Straw Covering" is disclosed. When the previous stubble is corn, rice and other crops with a large amount of straw, the seeds are sown and the crushed straw is covered, which solves the current problem. There are technical defects, but when the previous stubble of no-tillage sowing is corn, rice and other crops with a large amount of straw, if the straw is completely covered or returned to the field, there are the following problems:

1. After all the straw is returned to the field, the nitrogen in the soil is insufficient, which makes the microorganisms compete with the crops for nitrogen. As a result, the straw decomposes slowly, and the wheat seedlings turn yellow due to nitrogen deficiency, the seedlings are weak, and the growth is poor; the soil becomes too loose and the large pores are too large. If there are too many, it will lead to wind loss and moisture loss, which will affect the germination and growth of seeds, and make the wheat roots not firmly rooted and hang roots. the

2. Excessive straw coverage can easily lead to low low temperature in the early stage, which will affect the supply of nutrients; when the fertility is low or no fertilization is applied, the seedlings will not grow well, resulting in yellow and weak seedlings, delaying the growth and development of seedlings and even dying seedlings. the

For the above problems, the art hopes to have a technical solution that can overcome the above deficiencies. the

Utility model content

The purpose of this utility model is to address the above-mentioned deficiencies in the prior art, to provide a no-tillage wheat sowing machine in full-straw-covered land that can adjust the amount of straw-covered land, and to realize a shunt device with adjustable straw-covered amount for no-tillage operations in full-straw-covered land. A device that realizes partial straw returning and partial straw mulching, and the ratio of the amount of straw returning to the field and the amount of mulching can be adjusted. the

The purpose of this utility model is achieved by the following technical solutions. the

A no-tillage wheat planter with adjustable straw coverage, characterized in that it is configured as follows from front to back:

The tractor power output shaft is connected to the rotary knife shaft of the horizontal wide box-type straw crushing and cleaning machine perpendicular to the walking direction, and a plurality of straw crushing knives are arranged on the knife shaft, and a horizontal auger is behind the straw smashing knife;

An adjustment seam is horizontally opened on the upper cover panel between the straw cutter and the horizontal auger, and the adjustment seat bar is fixed on one side of the adjustment seam, and a rectangular adjustment plate is inserted in the adjustment seam, and the adjustment plate is fixed on the adjustment seam by bolts. on the seat strip;

The regulating plate blocks the straw crushed by the straw cutter from entering the horizontal auger;

There are multiple screw holes on the adjustment plate, and the bolts connect the screw holes at different positions, so that the depth of the adjustment plate inserted into the upper cover panel can be changed, and the amount of blocking the crushed straw from entering the horizontal auger can be adjusted;

The output end of the horizontal auger is equipped with a fan, which is sent backward through the pipeline to the top of the wheat fertilizing and seeding machine, and the range of straw thrown out is equivalent to the width of the wheat fertilizing and seeding machine;

A wheat fertilizing seeder is configured behind the horizontal auger. the

With this technical solution, an adjustment seam is horizontally opened on the upper cover panel between the straw cutter and the horizontal auger, and the adjustment seat bar is fixed on one side of the adjustment seam, and a rectangular adjustment plate is inserted in the adjustment seam, and the bolts The adjusting plate is fixed on the adjusting seat bar; the adjusting plate prevents part of the straw crushed by the straw cutter from entering the horizontal auger, thereby adjusting part of the straw returning to the field and part of the straw covering, so that the amount of straw returning to the field and the ratio of covering amount can be changed the goal of. the

Further, the one adjusting seam is divided into several sections, and the adjusting plate is correspondingly divided into several pieces. the

Further, the adjusting seat bar is a folded angle steel, one side is fixed on the upper cover panel, and the other side is provided with a screw hole. the

The beneficial effect of the utility model is that through the above-mentioned technical scheme, the adjusting plate prevents part of the straw from entering the horizontal auger, part of the straw is directly returned to the field, and part of the straw is covered by the auger and the pipeline, which can change the amount of straw returning to the field and the amount of coverage The ratio overcomes the problems such as returning all straw to the field or covering it completely. The technical solution has the advantages of simple structure, low cost, simple and reliable assembly and remarkable effect. the
