Corn stubble land residual film picking-up machine and stubble cutting and soil preparation method

Abstract

The invention provides a corn stubble land residual film picking-up machine and a stubble cutting and soil preparation method. The picking-up machine comprises a frame equipped with a traction frame, wherein a front ground wheel, a soil breaking and film removing device, a press roller, a soil-film separating device and a rear ground wheel are sequentially mounted below the frame, and an arched collecting device which can be lifted up and lowered down is arranged on the frame; and the press roller and the soil-film separating device can move up and down along the ground surface. The soil-breaking depth is controlled to be 50cm, the soil breaking and film removing device is used for pricking corn stubbles and breaking the ground surface, soil blocks, residual films and straws are mixed and flow back along the opposite direction of the soil breaking and film removing device, and substances with different weights can sequentially fall onto the ground surface; and after soil is broken, the soil-film separating device is used for re-separation, after the residual films and the straws are accumulated to a certain quantity in the arched collecting device, the arched collecting device is lifted up, and then the residual films and the straws in the arched collecting device can fall off. The residual film picking-up machine can pick up the residual films left in the stubble soil, break the roots of the stubbles and realize a new breakthrough in complex operation of seed production and corn planting, as well as mechanical picking-up of the residual films.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery manufacturing, and relates to a mulch pick-up machine, in particular to a mulch pick-up machine capable of breaking stubble roots, crushing crushed soil, raising the film to prepare the ground, and picking up and collecting the corn stubble; the invention also relates to The invention discloses a method for loosening soil and preparing soil while picking up corn stubbles by the corn stubble plastic film picker. Background technique [0002] Film mulching technology was introduced into my country in the 1970s. With its remarkable characteristics of heat preservation, moisture conservation, soil conservation, and production increase, it has greatly promoted the increase of farmers' income and agricultural production, and brought huge economic benefits to agricultural production. The "White Revolution" in Agriculture. With the promotion of mulching planting technology, the use of plast...

Problems solved by technology

However, while plastic film mulching technology brings significant economic benefits, it also causes serious white pollution to the land, which has become an urgent problem to be solved to maintain the agricultural ecological environment and promote sustainable agricultural development.

[0003] In order to remove the plastic film remaining in the soil, many forms of residual film picking machines have appeared, but the existing residual film picking machines can only pick up the residual film, and cannot break roots, break stubble, prepare the ground, and cannot cleanly and thoroughly remove the plastic film and plastic film. Straw on the ground, and it is impossible to pick up and remove the residual film on the corn stubble field. The plastic film left in the hard stubble soil can only be picked up manually, which is inefficient and labor-intensive.
