Mulching film recovery machine

Abstract

The invention discloses a mulching film recovery machine. The mulching film recovery machine comprises a frame body, and a rotary tillage device, wherein the rotary tillage device is arranged at the right lower side of the frame body, a feeding device is arranged at the left lower side of the rotary tillage device, a feeding conveyor is arranged at the left side of the feeding device, a sorting device is arranged at the left lower side of a feeding conveyor belt, the sorting device further comprises a rope screen conveyor composed of a driving grooved wheel, a driven grooved wheel and a rope ring, the lower left side of the rope screen conveyor is provided with a collection bucket, demoulding rollers are arranged between the rope screen conveyor and the collection bucket, the rope ring isalso wound with reversing wheels, and protrudes outward and is in contact with the demoulding rollers under the influence of one of the reversing wheels, and the rear side of the rope screen conveyoris provided with an impurity removal sieve plate. The scheme has the advantages of complete separation of impurities and high recovery efficiency of residual film in the soil.

Description

technical field [0001] The application belongs to the field of agricultural machinery, in particular to a plastic film recovery machine. Background technique [0002] At present, there is no qualified residual film recycling machine widely promoted. Cause the residual amount of soil plow layer to be very big (the average value of residual film amount in Xinjiang cotton field is 30kg / mu). The yield of crops has been seriously affected, and serious white pollution has been caused. The main reasons are as follows: Firstly, because the plastic film has the physical properties of non-rigidity but certain toughness, the plastic film is mixed with the adhered soil straw. Grass separation is more difficult; moreover, the current recycling methods of residual film recycling machines are basically picking up and recycling, and the state of collecting residual film is the whole film. Contains a lot of soil, straw and weeds. The harvested residual film cannot be disposed of, either i...

AI Technical Summary

Problems solved by technology

The yield of crops has been seriously affected, and serious white pollution has been caused. The main reasons are as follows: Firstly, because the plastic film has the physical properties of non-rigidity but certain toughness, the plastic film and the adhered soil straw are mixed. Grass separation is more difficult; moreover, the current recycling methods of residual film recycling machines are basically picking up and recycling, and the state of collecting residual film is the whole film. Contains a lot of soil, straw and weeds

The harvested residual film cannot be disposed of, either it is piled up in the field, and it is blown everywhere after the wind blows, and a considerable part returns to the cultivated surface; or it is burned or buried, causing secondary pollution

The problem has not been fundamentally solved, and the requirements for the recycling and reuse of the residual film have not been met; there is still a problem in collecting the whole film, which is the winding and clamping of the running parts of the machine, which makes the machine unable to work normally
