Farmyard plastic film residue recycling machine

Abstract

The invention discloses a farmyard plastic film residue recycling machine similar to a combination of an eccentric expansion link tooth pick-up machine and a roller rod tooth pick-up machine. The farmyard plastic film residue recycling machine comprises two film uncovering rollers, and six groups of pins are distributed on each roller. The pins complete film pricking, film picking, film transporting, film stripping and other actions to finish operation by the aid of a guide rail with a certainly eccentric cam. During rotating of the film uncovering rollers, a certain included angle is kept between the pins and rotating centers of the film uncovering rollers, so that during film stripping, the pins and film stripping scrapers can form larger film stripping angles, and film residues and the pins can be separated easily. Besides, a roller angle adjusting device is arranged between the two film uncovering rollers, so that the whole film uncovering machine can adapt to ridges in different specifications. The recycling machine is high in adaptability, small in size, small in mass, convenient to use, high in film recycling rate, convenient to dismount and maintain and widely applicable to film uncovering of dry land.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a machine for recovering residual film on farmland ridges. Background technique [0002] Film mulching is a mature agricultural cultivation technology, which can effectively increase and prolong the growth period of crops and ensure the increase of crop yield by retaining water, fertilizer and humidity. However, plastics are high-molecular compounds with high melt index (MI) and are extremely difficult to degrade. They are neither corroded by microorganisms nor decomposed by themselves. The degradation cycle is generally 200 to 300 years, and toxic substances will be dissolved during the degradation process. According to statistics, the annual residual amount of agricultural film in my country is as high as 300,000 to 400,000 tons, and the residual film rate is over 40%. It is undoubtedly a great hidden danger that nearly half of the agricultural film remains in the soil. W...

Problems solved by technology

Some residual film collectors can realize joint operations, but they can only integrate the residual film near the surface into strips, and the residual film of the integrated strips needs to be manually loaded and transported out of the field

On the basis of demonstration and popularization of the rake rake (92LZ-4.8) produced by Xinjiang Agriculture and Animal Husbandry Machinery Factory in Shache County, according to the working principle of the rake rake and the characteristics of the residual film recycling machine, it was restructured. It is troublesome to disassemble the residual film recycling machine, and the residual film machine recovers the residual film when plowing the ground. It can only recover the residual film within 1.5 cm of the ground surface, and cannot recycle the residual film below 1.5 cm.
