Description

Wheat seeder with full amount of straw that can realize automatic straw diversion control

technical field

The invention relates to the field of agricultural machinery, in particular to a wheat seeder with full amount of straw that can realize the automatic diversion and control of straw.

Background technique

The wheat seeder with full amount of straw can complete straw crushing, cleaning and throwing, rotary tillage sowing, and straw mulching at one time without any treatment on the previous crop straw, which provides strong support for the fertilizer utilization of straw returning to the field and the realization of burning ban. However, when the previous stubble is rice, corn and other crops with a large amount of straw, excessive straw coverage will cause wheat seedling shortage and weak seedling situation, which will affect the yield.

Patent No. 201410113918.7 "A No-tillage Wheat Planter with Adjustable Straw Coverage" discloses a no-tillage wheat planter with adjustable coverage, which can realize part of the straw into the soil and part of the straw mulch. And the amount of straw embedded in the soil and the proportion of coverage can be adjusted, but there are the following problems in practical application:

1. This technology prevents part of the crushed straw from entering the horizontal auger through the adjustment plate, and the rest of the straw enters the horizontal auger from the gap between the adjustment plate and the horizontal auger shell. When working in fields with a large amount of straw for a long time , The gap between the adjustment plate and the horizontal auger shell is easy to block the straw, resulting in machine failure.

2. There are differences in the amount of straw in different fields, which requires the operator to adjust the insertion depth of the adjustment plate when changing the field operation, which is time-consuming and laborious, and it is difficult for the operator to judge the amount of straw in the field before operation, so adjust Quantities cannot be determined in advance.

3. When operating in a certain field, the distribution density of straw in the field is often uneven, and this technology can only divert the straw according to the ratio set before the operation, resulting in poor uniformity of straw coverage and failure to fully utilize straw coverage The effect of sowing.

4. The insertion depth of the adjustment plate is changed through limited screw holes, and the adjustment accuracy is poor.

The above-mentioned problems have affected the application of the wheat planter with full amount of straw in the rice-wheat, corn-wheat rotation area, and the technical solution to overcome the above-mentioned shortcomings is hoped in the field.

Contents of the invention

Aiming at the above problems, the present invention proposes an automatic straw diversion control equipment suitable for a wheat seeder with a full amount of straw, which can automatically adjust the amount of straw covering and soiling according to changes in the amount of straw in the field. The specific plan is as follows:

Further, the gearbox is connected to the first pulley of the rotary cutter shaft through a belt, and a second pulley is also arranged on the rotary cutter shaft, and the second pulley is connected to the auger shaft through a belt.

Further, ground rollers are arranged below the rear of the frame.

Further, a tripod is arranged on the front and upper part of the frame, and the tripod is provided with a pin hole fixed with the traction device.

Further, the arc length of the straw retaining plate is greater than the arc length of the straw unloading door.

Further, the rolling bearing is a deep groove ball bearing.

The innovation point of the present invention is:

1. Before operation, adjust the spring and bevel gear transmission ratio to control the diversion ratio. During operation, the tool automatically realizes the stepless regulation of straw diversion according to the actual straw amount in the field. The whole process does not require manual operation, saving time and labor.

2. The straw retaining plate can be opened and closed through the change of conveying load, so the straw conveying parts will not be jammed.

3. The dynamic split flow automatic adjustment function can ensure that the amount of straw coverage is basically the same, and the uniformity of straw coverage is better than that of similar models, which avoids the problem of lack of seedlings and weak seedlings caused by excessive straw coverage, and also takes into account the advantages of straw coverage. A series of functions such as heat preservation and moisture conservation.
