Multi-crop united screening and sowing machine for wheat, rice, grass and vegetables

Abstract

The invention belongs to the technical field of tillage sowing machines, and discloses a multi-crop united screening and sowing machine for wheat, rice, grass and vegetables. The multi-crop united screening and sowing machine is mainly technically characterized in that the machine comprises a frame, a fertilizer case with a fertilizer tube, a seed case with a seed tube, a trenching and banking device, a fertilizer evening plate, a rotary blade, a compressing device and an upscraper are arranged on the frame, a grate-type sowing device composed of a grate beam and hollow tubular grates is arranged on the frame, the hollow tubular grates arranged densely are fixed on the grate beam, the bottom ends of the hollow tubular grates are close to the ground, the upper ends of the hollow tubular grates are connected with the seed tube, and an adjusting mechanism is arranged between the grate beam and the frame. The screening and sowing machine is provided with the grate-type sowing device, is suitable for combine even planting of crops of wheat, rice and the like in varied zoology areas, and is suitable for sowing vegetable seeds in fields. Field crops can be sowed evenly and covered with earth like vegetables; the seeds are in the same earth layer and saved; the seedlings come out tidily and evenly; and the advantage of even planting of the crops can be completely achieved.

Description

technical field [0001] The invention belongs to the technical field of cultivating and sowing machines, in particular to a combined screening and sowing machine for multiple crops of wheat, rice, grass and vegetables. Background technique [0002] Various crops such as wheat, rice, grass, and vegetables have different methods of soil preparation and sowing. Some are directly sown in large fields, which are suitable for large-scale cultivation of bulk crops. The operation procedures are simple and extensive, easy to mechanize, and high in operation efficiency. And what have needs to carry out field border seedling raising or field border sowing, and the procedure of soil preparation and seeding is fine and loaded down with trivial details, and efficiency is low, only suitable for the raising of seedlings of small economic crops such as vegetables or bulk crops. For thousands of years, the sowing of field crops generally adopts the method of ditching and drilling with machines...

AI Technical Summary

Problems solved by technology

Others need to raise seedlings or seedlings in the field. The procedure of soil preparation and sowing is tedious and cumbersome, and the efficiency is low. It is only suitable for raising seedlings of small economic crops such as vegetables or bulk crops.

For thousands of years, the sowing of field crops generally adopts the method of ditching and drilling with machines and tools. The applicant's patent number is "200620127802.X", and the patent name is "Wheat Combined Spreader". In the new era, it was later improved to a wheat ridge-free combined tillage and seeding machine, and the uniform planting method of sowing and rotary tillage. The seeds are not in the same soil layer, which not only wastes seeds, but also has irregular seedling emergence, poor uniformity, patchy lack of seedlings, and cannot give full play to uniform planting. The advantages

Later, although wheat spreaders were improved so that the seeds were placed in the same soil layer, the application conditions were harsh. Not only did the strict requirements on soil quality and moisture content not match the actual production, but it could not be directly applied in the case of straw returning to the field.

Compared with the extensive cultivation of field crops, paddy rice seedling raising and vegetable sowing are horticultural operations, and the procedures are fine and cumbersome. Generally, it is necessary to plow the land first to make a furrow, and then rake the ground to remove the surface finely divided soil and pile it up separately. Put it on the outside of the furrow, flatten the furrow again and spread the seeds evenly, then cover the furrow evenly with the topsoil placed on the outside of the furrow, and then re-irrigate to complete, which is labor-intensive and water-intensive. work without mechanization
