A Soil Scraping and Suppression Profiling Device with Wide Compartment

Abstract

The invention relates to a partition soil scraping and pressing profiling machine suitable for being used after seeding and film mulching, in particular to a large-breadth partition soil scraping and pressing profiling device, and belongs to the technical field of agricultural machines. The large-breadth partition soil scraping and pressing profiling device comprises a rack, soil scraping plates and a pressing roller, and is characterized in that the two soil scraping plates are fixed to the front lower portion of the rack in a splayed mode through a front hitching device and rear connecting rods, the minimum distance between the front ends of the two soil scraping plates ranges from 150 mm to 300 mm, and the pressing roller is installed on the lower portion, behind the soil scraping plates, of the rack through a rotating shaft and supporting rods. The large-breadth partition soil scraping and pressing profiling device is simple in structure; the soil scraping surface is reduced by 25%, the passing ability is improved, the jamming rate is reduced to less than 3-5%, and the soil scraping energy consumption is reduced by 35-50%; a film space for growth of cotton seedlings is formed after soil scraping and pressing, and the sun burn rate of the seedlings is reduced to less than 0.1%; soil scraping stability and seeding depth uniformity are guaranteed.

Description

technical field [0001] The invention relates to a soil scraping and suppressing profiling machine for compartments suitable for sowing and filming, in particular to a soil scraping and suppressing profiling device for wide compartments, which belongs to the technical field of agricultural machinery. Background technique [0002] Nowadays, cotton planting generally requires film-laying and sowing, and the surface is scraped, fertilized, sown, film-covered and soil-covered and suppressed at one time through the film-laying seeder. Existing sowing machinery is only limited to the conventional planting mode of mulch film width 950 millimeters, sowing row spacing 450 millimeters. At present, the cotton mechanized harvesting and sowing mode adopts the sowing mode with a film width of 1300 mm and a sowing row spacing of 760 mm. At present, the soil scraping and suppressing devices of film-laying seeders are generally "human" character scraping and suppressing devices. In order to...

Problems solved by technology

However, such improvement will bring many defects: increasing the angle of the "herringbone" type scraping device will cause many problems in the fluidity of the soil in the scraping device, and it will be easily blocked, making the machine not work normally; increasing the " The length of the "herringbone"-shaped scraping device, although the fluidity of the soil is less affected, but with the increase of the length, it will cause the soil to stay on the scraping device, which will also cause congestion and increase the machine tool. load, and increases the longitudinal dimension of the implement

At the same time, the "herringbone"-shaped soil scraping and suppression device scrapes the entire film-laying line flat, which makes it easy to directly contact the film after the cotton seedlings emerge, causing burns to the cotton seedlings under sunlight
