Embodiment

[0021] Example: A method for picking up residual film

[0022] Including the following steps:

[0023] (1), film picking: driven by the transmission mechanism 2 installed on the frame 1, the film picking device 3 with a higher speed drives the three rows of spring teeth 4 arranged on the film picking device, and the diameter of the spring teeth is 5 mm , when the spring tooth 4 enters the soil and is perpendicular to the ground, the linear velocity direction X at the top of the spring tooth and the forward direction X of the film picker 1 On the contrary, the linear velocity v=25 m / s at the top of the spring teeth, the depth of the spring teeth h=5 to 10 cm, most of the residues in the soil will be dislodged by the deformation of the spring teeth and its high linear velocity during work. The membrane is lifted into the air to achieve the separation between the membrane and the soil;

[0024] (2) Film collection: The fan 5 at a distance of 1.0 meters from the film picking dev...

Abstract

The invention relates to a method for collecting residual film, which comprises: the high-speed rotating of the residual film-collecting device equipped with spring tines, which makes the linear speed in the top of spring tine reach 10-30m / s and makes a large part of the residual film in soil float in the air, reach the effect of separating the film and soil; the air flow with the speed of 3-20m / s provided by fan or air-supply arrangement forms a air-bed with a certain thickness in the air up the working area, which makes the floating film can not fall to ground easily; the floating property of the film can also reach the effect of separating the soil and the floating film further; blowing the floating residual film into the film-collecting device in the end.

Description

technical field [0001] The invention belongs to the recycling process of residual plastic film in agricultural machinery, and in particular relates to a method for picking up residual plastic film. Background technique [0002] Although the production of crops is improved when plastic film is covered, a large amount of residual film is left in the soil, which obviously hinders the sustainable development of agriculture. [0003] In order to solve the problem of residual film in the soil, many people have designed many kinds of residual film picking machines. In summary, there are three main types, namely, film picking machines at seedling stage, film picking machines after autumn and film picking machines before sowing. But because the existing residual film pick-up machine all has some miscellaneous defects, thereby fails to be popularized and applied on a large scale. [0004] From China Agricultural Mechanization, 2004, (6), 68~71, "Residual Film Recovery Process Discuss...
