The separating ring chain wheel 43 on the separating ring 32 is driven by the chain 42, but the rotation direction is opposite to that of the grabbing rolling ring 21, therefore, when the device works, the grabbing rolling ring 21 grabs the waste plastic films from the shallow ground surface, the waste plastic films are lifted upwards along with rolling, the second grabs 33 crossed in the ground grabbing rolling ring 21 roll along with the separating ring 32, the first grabs 22 of the grabbing rolling ring 21 are lifted upwards from the mixture of the plastic films and the residue soil and the like grabbed from the ground surface, and the residue soil and the stone are thrown back to the ground surface by using the action of gravity.

Specifically, referring to fig. 7, in the present embodiment, the tooth pulling belt conveyor 52 includes a primary rotating wheel 521, a secondary rotating wheel 522 and a belt 523 adapted to be mounted on the primary rotating wheel 521 and the secondary rotating wheel 522, the primary rotating wheel 521 and the secondary rotating wheel 522 are both rotatably mounted at the upper end of the frame 11 through a rotating shaft, teeth 524 are uniformly distributed on the outer surface of the belt 523, the teeth 524 and the second gripper 33 are staggered at the intersection, and the direction of the teeth 524 and the second gripper 33 during operation is opposite, so that the waste residual films on the second gripper 33 are pulled out by the teeth 524 toward the rear of the belt 523.

Because part of the residual leaves are still wrapped by the residual film in the lifting process, the plastic residual film after the separation of the stones and the dregs needs to be further cleaned.

In the present embodiment, above the intersection of the separating ring 32 and the toothed belt conveyor 52, a rod-type electrostatic generator 51 is arranged, the model being: the CKD-CS20/30/50 series electrostatic generator has the maximum input power of 45W, the maximum output power of 20W and the output voltage of 0-50kv, the positive and negative poles can be adjusted according to the requirements of customers, and the infrared remote control is adjusted in the 0-12v gear. When the plastic residual film passes through, the plastic residual film is charged by electrostatic ions, and the charged charges move backwards and rotate along with the belt 523 and the tooth 524 on the tooth pulling belt conveyor 52.

When the plastic reaches the tail end of the tooth pulling belt conveyor 52, due to the property difference of the material composition, after the plastic is charged, the positive charges and the negative charges in the plastic are arranged clearly and strongly and are adsorbed on the belt 523 to move along with the movement of the plastic, the residual leaves are plants in nature, and the electric field adsorption force borne by the residual leaves is far smaller than that of the plastic residual film when the residual leaves reach the tail end of the tooth pulling belt conveyor 52, so that the residual leaves are separated and thrown away by centrifugal force and gravity.

A rod type static electricity removing blower 53 is also arranged at the lower part of the gear-pulling belt conveyor 52, the model is CKD-Q5F ion wind rod (discharge type), and the power supply and the air source can be supplied by a tractor.

Therefore, the abandoned leaves are received by the partition plate 62 arranged at the oblique lower part of the tail end of the belt conveyor with the very short distance pulling teeth and slide to the farmland. And the residual film is brushed down by the fork teeth of the residual film cleaning rack 61, falls into the residual film recycling hopper 63, and slides into the recycling bag.

The working process is as follows: during operation, the tractor pulls the rack 11 to walk at a constant speed in a farmland, the walking wheels 14 and the grabbing rolling rings 21 share one first rotating shaft 13, and the first rotating shaft 13 is connected with the rack 11 through a bearing. The first gripper 22 on the grabbing rolling ring 21 grabs the waste plastic film residues from the ground during walking, the waste plastic film residues are lifted upwards along with the rotation of the grabbing rolling ring 21, and a large amount of soil residues and stones are thrown away under the action of the gravity of the earth. The gravity residual soil lifting mechanism 30 is mainly composed of a separating ring 32 and second grippers 33 which are alternately inserted on the grabbing rolling ring 21, in the process that the first grippers 22 of the grabbing rolling ring 21 lift the waste residual films upwards, the waste residual films are peeled off by the second grippers 33 which are opposite in rotation direction and are alternately inserted on the separating ring 32, the waste residual films are lifted again, and the residual soil and stones which are wound inside are further lifted.

However, the shape and mass of the plant residual leaves wound in the waste residual film are similar to those of the residual film, and the plant residual leaves are difficult to separate only by the action of gravity, so that the residual leaves mixed in the residual film are subjected to electrostatic separation after stones and residue soil are thrown away in gravity separation.

The electrostatic residual leaf separating mechanism 50 is composed of a rod type electrostatic generator 51, a tooth pulling belt conveyor 52, a rod type electrostatic air blower 53 and the like. When the separating ring 32 rotates the waste plastic film wrapped with the plastic film to the other side again, the waste plastic film on the second gripper 33 is pulled out by the pulling teeth 524 on the pulling-out belt conveyor 52 arranged at the other side, and then the waste plastic film rotates backwards. A bar type static generator 51 is arranged above the junction of the second gripper 33 of the separating ring 32 and the gear-shifting 524 on the gear-shifting belt conveyor 52, and blows static ions into the waste residual films to charge the waste residual films. The charged charges move back and rotate with the belt 523 and the teeth 524 on the toothed belt conveyor 52. When the plastic residual film reaches the tail end of the conveying belt, due to the property difference of the materials, after the plastic residual film is charged, the positive charges and the negative charges in the plastic residual film are arranged clearly and are relatively and strongly adsorbed on the belt 523 to move along with the belt, while the residual leaves are plants in nature, and when the plastic residual film reaches the tail end of the belt 523, the adsorption force of an electric field applied to the plastic residual film is far smaller than that of the plastic residual film, and the plastic residual film is separated and abandoned by centrifugal force and gravity. The abandoned residual leaves are received by a partition plate 62 arranged obliquely below the tail end of the tooth pulling belt conveyor and slide to the farmland. A rod-type static electricity removing blower 53 is also arranged at the lower part of the gear-pulling belt conveyor 52, static electricity on the plastic residual film is cleaned along with the plastic residual film brought to the lower part by the gear-pulling belt conveyor 52, and the plastic residual film is brushed down by a residual film cleaning rack 61 carried by the device, falls into a residual film recycling hopper and slides into a recycling bag.

The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the protection scope of the claims of the present invention.
