Anti-sag film seeder

Abstract

The invention relates to an agricultural machine tool, in particular to an anti-sinking laminating seeding machine which comprises a machine frame (1), a mulching film scroll (4) and a seed tray (6). The anti-sinking laminating seeding machine is characterized in that a roller (11) is installed at the position below the machine frame (1) and in front of the mulching film scroll (4), and the diameter of the roller (11) varies repeatedly to form a plurality of concave and convex ring-shaped waves (12). The anti-sinking laminating seeding machine has the advantages that the waves of the roller has special mechanical performance and can press loose soil in a wave trough, a plurality of high-density indentations with the sections in wave shapes are formed, namely the local load bearing strength of the soil is improved, pressure of the whole machine tool can be supported, the phenomenon that the machine tool sinks to stack soil is eliminated, uninterrupted rapid stable advancing is achieved, a film is laminated flatly and tightly, the fertilizer distributing quantity and seeding position are accurate, drought-resisting, water-saving and yield increase effects are extremely remarkable, and a new way is opened up for popularization of the film-laminating technology.

Description

technical field [0001] The invention relates to an agricultural implement, namely an anti-sinking film-covered seeder. Background technique [0002] Plastic film mulching is an effective anti-drought technology in farmland, that is, plastic film is spread on the ground with a plastic film seeder when sowing to prevent water from evaporating. Existing film-covered seeder is made of frame, film roller, sowing wheel etc., what have is also equipped with fertilizer box and ground wheel, is towed by tractor operation. Since the film is only 0.004mm thick and is easily damaged, it has high requirements on field hygiene and soil properties. For this reason, before sowing, use a rotary tiller to break up debris and loosen the soil so that the ground is as flat as a mirror and the soil is as fine as a surface. However, when the above conditions are met, the strength of the plow layer is already difficult to bear the weight of the mulching machine, and the machine will continue to s...

AI Technical Summary

Problems solved by technology

At present, the water pipe under the film can only be laid manually in front of the film planter, which is low in efficiency and high in cost

If the problem of soil subsidence of the film-covered planter is solved, the speed of the machine tool will be accelerated, and the manual laying of water pipes will be difficult to meet the needs of the operation

[0005] 2. The process of unrolling the mulch film from the reel downwards and laying it on the ground of the existing machine tool is mainly by pulling the seeding disc. Pulling it in a row is easy to cause tearing, the flatness of the film is very low, the position and size of the perforation are not accurate, and the water retention performance is affected

Because the mulch film is easy to scratch, the existing machinery can only cover soil on both sides of the mulch film, but it is difficult to cover the mulch film with soil, and it is difficult to meet the agronomic requirements

[0007] 4. The existing equipment has only one mulch reel, and sometimes the mulch is used up in the middle of the journey, so the mulch reel can only be transported from a long distance, which is laborious and time-consuming
