Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery and relates to a double-acting demoulding roller of a ground film picker and a spring brush suitable for a machine for recycling and cleaning residual film in farmland. Background Art

[0002] Since the last century, with the rapid development of the plastics industry, mulching cultivation technology has been widely used in the fields. Mulching cultivation technology has the advantages of heat preservation, moisture retention, inhibition of weed growth, improvement of soil aggregate structure and increase of crop yields. It is the most effective means of increasing production in agricultural production. Mulching technology has been used in Europe, the United States and Japan since the 1950s. Due to its significant economic benefits, it has soon been widely used around the world. However, agricultural plastic film is extremely difficult to degrade under natural conditions. If the mulch is left in the soil, it will cause a series of serious hazards to agricultural production itself. Therefore, the mulch must be recycled in time. At present, my country ranks first in the world in terms of mulch coverage area and usage. Mulching technology is particularly widely used in Northeast and Northwest my country. The cultivated land area using mulch in my country has reached tens of millions of hectares, and the annual consumption of mulch has reached millions of tons. Mulch has become one of the indispensable agricultural production materials in my country's agricultural production. Due to price factors, the mulch materials used in most parts of my country are polyethylene and polyvinyl chloride. This material remains in the soil for hundreds of years without being easily degraded, and a large amount of residual film fragments remain in the soil during recycling, resulting in poor water circulation, hindering the exchange between soil and air, making it difficult for microorganisms in the soil to survive, causing soil compaction, and may lead to salinization of the land in some areas, resulting in a significant drop in crop yields. Especially after being blown by the wind, buried or burned, it can be seen everywhere in the fields, seriously polluting the living environment and air quality of farmers, and ultimately leading to serious "white pollution".

[0003] At present, there are three main methods for recycling residual film in China, namely manual picking, using degradable film and mechanized recycling. Manual picking has the disadvantages of low efficiency, large labor volume and limited operation range, and residual film buried in deep soil cannot be recycled. This recycling method is gradually being eliminated with the reduction of labor and the improvement of agricultural machinery level. Degradable film is a new type of environmentally friendly mulch film, which is mainly made of a mixture of plastic particle masterbatch and biodegradable masterbatch. After use, it can be very well decomposed into the soil; but this type of degradable film has a high cost and the technology is not mature. At this stage, it is difficult to be accepted by the majority of farmers, especially small and medium-sized farmers, and its promotion in China is limited. Mechanized recycling has the advantages of high efficiency and low cost, which largely makes up for the shortcomings of manual recycling and degradable film recycling methods. my country started research on residual film recycling machinery early, and the earliest related patents can be traced back to the 1980s. Since the research, a variety of residual film recycling machines have been developed and tested and promoted. Despite this, the residual film pollution phenomenon is still serious, and the problems of low recovery rate of residual film recycling machines have not been well solved. Most areas still rely on manual collection of residual film. In order to further improve the quality of residual film recycling, it is urgent to conduct a systematic study on the functional components of existing residual film recycling machines, sort out and summarize their structural characteristics and operating principles, and provide guidance for the further design and optimization of residual film recycling machines. Summary of the invention

[0004] In order to meet the needs of recycling and cleaning residual film in farmland, a double-acting demoulding roller with a spring brush for a film picker was developed. This mechanism is an important component of the high-negative-pressure residual film picker.

[0005] The utility model solves the technical problem by adopting a technical solution: a double-acting demoulding roller with a spring brush for a ground film picker, which is composed of a shaft roller, a rigid demoulding sheet and a flexible demoulding wire. The rigid demoulding sheet is evenly installed on the cylindrical surface of the shaft roller, and the flexible demoulding wire is installed in the gap between the rigid demoulding sheets.

[0006] The beneficial effects of the utility model are easy installation, simple structure and strong reliability. The double-acting demoulding roller of the ground film picking machine can cope with demoulding in various working conditions and meet the functional requirements of effective demoulding of the negative pressure residual film picking machine.
