Separable residual plastic film recovery device of straw returning machine

Abstract

The invention relates to the technical field of agricultural residual plastic film recovery machines, and discloses a separable residual plastic film recovery device of a straw returning machine. Theseparable residual plastic film recovery device comprises a film collecting machine body and a separable straw returning device which is located at the front end of the film collecting machine body. The straw returning device comprises a returning rack, a returning gearbox and a straw smashing device with a flailing knife. The separable residual plastic film recovery device is reasonable and compact in structure and convenient to use; the separable residual plastic film recovery device is connected with the straw returning device through a returning connecting frame, a film collecting connecting frame and adjusting pull rods and can be conveniently separated from the straw returning device. Convenience is brought for a user to a select a tractor with large horsepower or medium horsepower for work, and the problem that power of a tractor and power of a residual plastic film recovery device are not matched is effectively solved. Besides, by forming impurity removal holes and replacing chain wheels with pulleys, the equipment can solve the problem of chain hole blockage caused by residual plastic film so that a spike tooth chain belt can efficiently and continuously work, the applicability is high, the residual film recovery effect is good, the equipment work efficiency is high, and the separable residual plastic film recovery device has the advantages of being safe, capable of saving labor, simple, convenient to use and efficient.

Description

technical field [0001] The application relates to the technical field of agricultural residual film recovery machinery, and relates to a detachable residual film recovery device for a straw returning machine. Background technique [0002] Agricultural mulch is widely used in the planting of various crops, especially cotton, but agricultural mulch needs to be recycled in a timely and effective manner to avoid environmental pollution, soil compaction, and degradation. In order to avoid the influence of straw in the field on the recovery of residual film after autumn, it is usually necessary to crush the cotton straw and return it to the field before recycling the residual film. Returning the straw alone is more time-consuming and the corresponding operating cost is higher. At present, the existing integrated residual film recovery machinery that can realize cotton straw returning to the field and residual film recovery is more efficient, but its size is usually large, consumes...
