The utility model relates to the field of land preparation agricultural tools in agriculture, in particular to a plastic film cleaner, which is mainly applicable to uncovering and removing plastic film discarded in tobacco fields, including a handle and a rake part. Several rake teeth are arranged on the rake part, the front part of the rake teeth is bent downward, and the rear part of the rake teeth extends outward along the periphery of the rake teeth and is even. Distributing hook teeth, the front part of the rake teeth is provided with a film-coiling component, which includes a rotating bearing and a film-coiling drum. The rotating bearing sleeve is on the rake teeth, the film-coiling drum sleeve is on the rotating bearing, and the outer wall of the film-coiling drum is covered with a number of uniformly distributed film-coiling teeth. The film-coiling teeth are arranged in two intersections along the axial helix of the film-coiling drum. The design is durable, time-saving, labor-saving, quick and convenient to grasp film. The rotatable film-rolling parts are not easy to crumble when sweeping film. They can pick up the film and roll it up at the same time. The residual rate of the film is low and the cleaning is cleaner. It can effectively remove the plastic film remaining in the field soil, thus reducing the pollution to the soil environment. Dyed.

地膜清除器
本技术涉及农业中的整地农具领域,尤其是一种地膜清除器,主要适用于烟地里废弃地膜的揭膜、除膜工具。
技术介绍
烟草地膜覆盖栽培技术自20世纪80年代研究、示范、推广以来,面积逐年扩大,目前已是高海拔烟区优质烟叶生产的一项不可缺少的重要技术。在高海拔烟区,针对当地的实际情况,因地制宜的制定相应的烟草地膜覆盖综合配套技术措施,能够显著的提高烟叶的产量和质量。在烟叶生长前期,烟田覆盖地膜可以增加地温,保水,保肥,防止出现低温冻害和早花现象,促进烟苗移栽后早生快发,增产、增质、增效效果明显。但是,烟株生长后期不揭膜,会出现第二次吸肥高峰,导致烟株易早衰、抗倒伏性和抗逆性变差、病虫害加重,使烟叶的烟碱含量过高,化学成分的比例失衡,降低烟叶品质等问题。因此,烟株在移栽后30—35天,应及时揭除地膜,改善土壤通透性,增加土壤接收降雨的面积,使根际得到较多雨水补给;使在揭膜前产生的气生根能和土壤充分结合,扩大根系对土壤营养的吸收面,从而促进烟株早生快发,促进烟株正常生长。现有清除田间废旧地膜一般采取人工或机械的方式,国内先后专利技术了多种田间废旧地膜清理回收机械,但是, ...
