A device for embedding plastic film on a seeder

Abstract

The invention provides a device for embedding plastic film on a seeder. The front end of the frame body is provided with a connecting frame for connecting with the seeder. The film pressing mechanism, the film pressing wheel, the film brushing mechanism, and the film covering plow; The quantity is 2, and a mulch pressing wheel and a mulching soil plow are respectively installed on the left and right sides of the connecting frame; Level and expel excess air from under the mulch. The invention can eliminate excess air in the laid mulch as much as possible through the elastic contact-type mulch initial laying and pressing mechanism and the mulch brushing mechanism, so as to keep the surface of the mulch flat, enhance its wind resistance, and prevent it from being subjected to long-term Torn apart by the wind.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a device for embedding and pressing mulch on a seeder. Background technique [0002] Use a film-covered seeder to spread plastic film on the ground after sowing, which can keep warm and prevent water from evaporating. During the laying of the film, it is easy to cause too much air to be covered under the film, resulting in too much air under the film, causing the air in the laid film to flow easily under the action of external wind, making the film bulge and fluctuate with the wind. The general film is thin, so it is easy to cause damage to the film, which greatly reduces the effect of heat preservation and moisture retention. Therefore, it is necessary to remove excess air as much as possible during the film laying process to enhance its wind resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the ab...

AI Technical Summary

Problems solved by technology

During the laying of the film, it is easy to cause too much air to be covered under the film, resulting in too much air under the film, causing the air in the laid film to flow easily under the action of external wind, making the film bulge and fluctuate with the wind. However, the general film is relatively thin, so it is easy to cause damage to the film, which greatly reduces the effect of heat preservation and moisture retention. Therefore, it is necessary to remove excess air as much as possible during the film laying process to enhance its wind resistance.
