Paving and soil-covering integrated machine of mulching film

Abstract

The invention discloses a paving and soil-covering integrated machine of a mulching film. The machine includes a main rack (3), a rear bearing piece (1), a rear-hitch drawing apparatus, a large wheel set (18), a small wheel set (9), a distance adjusting beam (33), a sliding cylinder (19), a first-stage film pressing roller (39), a second-stage film pressing roller (38), film pressing roller lugs (15), a soil covering apparatus, a front bearing piece (4), a mulching film sleeve hanging ring, a front-hitch drawing apparatus and a mulching film sleeve rod (11). The machine is pulled by dynamic power, so that the mulching film can be paved flatly and quickly and is free of being damaged. Through multi-stage film pressing, the mulching film is ensured to be flat, and through friction between ground and the film pressing rollers, tension force of multiple points is ensured, thereby effectively ensuring uniform distribution of tension force on the mulching film during the paving process and ensuring the mulching film to be not liable to be lifted due to external force. The machine has low requirement on thickness of the ground film, has a wide adaptability range on mulching films, and has strong modificability on structure and functions.

Description

technical field [0001] The invention relates to the field of devices for laying protective coverings for plants in the field of protection of cultivated species of agricultural gardening, vegetables, flowers, rice, fruit trees, grapes, hops or seaweed, especially an integrated machine for laying mulch and covering soil. Background technique [0002] There are a lot of mechanical laying or manual laying equipment for the film in the prior art. The mechanical laying is mainly hung on the mechanical equipment for laying, and generally consists of a film release roller, support wheel and soil plow (or soil wheel). It is composed of main components, and it does not have a film structure, and does not have a structure that squeezes out the air between the film and the ground surface. In actual use, there are the following technical problems. The first is to directly rely on traction to pull the film, and only rely on the opening of the film.

AI Technical Summary

Problems solved by technology

[0002] There are a lot of mechanical laying or manual laying equipment for the film in the prior art. The mechanical laying is mainly hung on the mechanical equipment for laying, and generally consists of a film release roller, support wheel and soil plow (or soil wheel). It is composed of main components, and it does not have a film structure, and does not have a structure that squeezes out the air between the film and the ground surface. In actual use, there are the following technical problems. The first is to directly rely on traction to pull the film, and only rely on the opening of the film. Pull force is used to achieve tension, which makes the film vulnerable to the wind during laying, resulting in large fluctuations and easy damage during the laying of the film, which requires the use of thicker film, which will undoubtedly increase the cost and reduce the laying speed , this is the problem caused by the structural design without film-pressing rollers. The second problem is that there is a lot of air in the process of laying the film, that is, it is uneven. In places with strong winds, it is easy to cause the film to be lifted. The problem caused by the unreasonable design between the film roller and the laminating roller. The third problem is that the function is single, and there are few additional structures and functions. As for the manual laying equipment and the mechanical laying equipment of the film, the only difference is the traction The power is different, the mechanical laying equipment of the mulch film is mechanical traction, and the manual laying equipment is human propulsion and traction. There is no difference in other technical structures and use shortcomings between the two.
