Description

Technical Field

[0001] The invention relates to the technical field of residual film recovery, and in particular to a device for recovering tiny residual films in farmland soil based on high voltage static electricity. Background Art

[0002] At present, the residual film in farmland of Xinjiang is mainly recycled by residual film recycling machines. According to the operation time and agronomic requirements, the residual film recycling machines can be divided into three categories: residual film recycling machines in seedling stage, residual film recycling machines after autumn and residual film recycling machines before spring sowing.

[0003] However, although the existing soil micro-residue film recovery device can effectively recover about 80% of the film in the farmland when in use, it cannot effectively remove the micro-residue film in the soil.

[0004] In order to solve the above-mentioned defects, in the prior art, a Chinese patent with publication number CN213972070U discloses a device for recovering residual film from farmland. Through transmission connection, when the servo motor drives the No. 2 rotating shaft to rotate, the sweep wheel can also be driven to move through the belt. The No. 1 bevel gear at the front end of the No. 2 rotating shaft drives the tamping rod to tamp up and down, so that a servo motor drives the rake teeth, the sweep wheel and the guide rod to work at the same time, which is convenient for saving energy. By tamping the vibration plate with the tamping rod, most of the soil adhered to the residual film can be shattered, which is convenient for the subsequent screen to screen out the soil on the residual film and also convenient for the subsequent treatment of the residual film. The No. 2 pulley is driven by the No. 2 rotating shaft, and the No. 1 pulley is connected to the No. 2 pulley through a conveyor belt transmission. The rake teeth on the conveyor belt can turn over and hook the residual film from the soil. When it is transmitted to the upper part of the box, the rotating sweep wheel can sweep the residual film off in time.

[0005] In the prior art, a Chinese patent with publication number CN221264631U discloses a device for recovering farmland mulch film, comprising a frame, movable wheels are installed at the outer ends of the frame and near the four corners, and a pair of support blocks are fixedly connected to the top of the frame, mounting blocks are rotatably connected to the inner parts of the pair of support blocks, and a winding roller is detachably installed between the pair of mounting blocks. During the mulch film winding and recovery process of this scheme, the rotating shaft and the cam at the outer end can be driven to rotate under the transmission action of the belt, so that the piston at one end of the piston rod performs reciprocating piston motion in the boosting box, and the water tank is pressurized. The cleaning liquid in the water tank can soak the wiping piece, and the wiping piece filled with the cleaning liquid abuts against the mulch film. As the mulch film moves, the mulch film can be cleaned to remove attached soil, pesticide residues and other impurities, which helps to reduce the residual pollutants after the mulch film is recovered and improve the quality of the recovered mulch film.

[0006] During use, the above-mentioned device utilizes a vibration plate to break up the soil to which the residual film adheres, so as to facilitate screening of the soil on the residual film. However, in the above-mentioned device, the vibration plate only breaks up the soil to which the residual film adheres, and the recovery effect of tiny residual film is poor, resulting in many tiny residual films remaining in the soil. Therefore, in actual use, the recovery effect of tiny residual films is poor, resulting in residual films remaining in the soil. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) By starting the reduction gearbox, the reduction gearbox drives the output shaft to rotate, the output shaft drives the belt 1 to rotate, the belt 1 drives the drive shaft to rotate, the drive shaft drives the belt 2 to rotate, and the belt 2 drives the throwing roller 1 to rotate, so that the soil can be thrown and the transmission efficiency can be improved. The soil mixture is scooped up by the digging shovel, and the electrode plate 1 charges the soil mixture. After the soil mixture is positively charged by the electrode plate, it is thrown by the throwing roller 1, which is convenient for loosening and separating the soil mixture, and can reduce the adsorption distance of the tiny residual film, and the adsorption capacity is stronger;

[0020] (2) The conveyor belt 1 is driven to rotate by the driving shaft, and the conveyor belt 1 transmits the separated soil, and the driving shaft drives the belt 3 to drive the rotating rod to rotate, and the rotating rod drives the conveyor belt 2 to rotate, so that the residual film in the soil mixture is attracted by the electric charge greater than its own gravity and is adsorbed to the negatively charged conveyor belt 2, and is transmitted through the conveyor belt 2, thereby improving the transmission efficiency;

[0021] (3) The support rod is driven to rotate by the conveyor belt 2, and the support rod drives the gear 1 and the gear 2 to mesh and operate, and the gear 2 drives the film brush roller 1 to rotate, and the film brush roller 1 brushes off the residual film adsorbed on the conveyor belt 2 and drops it into the film collection box, while other substances in the soil mixture continue to be transported by the conveyor belt 1. These processes form the first separation of the tiny residual film of the soil mixture;

[0022] (4) By starting the high-voltage electrostatic generator, using the battery pack to power the high-voltage electrostatic generator, and supporting the high-voltage electrostatic generator and the battery pack through the support plate, the equipment can be operated stably;

[0023] (5) By starting the stepper motor, the stepper motor drives the transmission shaft to rotate, the transmission shaft drives the output screen to rotate, the output screen drives the driving gear rod to rotate, the driving gear rod and gear three are meshed and operated, and gear three drives the film brushing roller two to rotate, so as to facilitate the brushing of the residual film in the transmitted soil mixture, and facilitate the secondary separation of the residual film;

[0024] (6) The conveyor belt 1 drives the limit rod to rotate, the limit rod drives the conveyor belt to rotate, and the conveyor belt drives the throwing roller 2 to rotate, and finally the soil mixture is thrown onto the output screen rotating counterclockwise. Since the mass of other substances in the soil mixture is greater than the mass of the residual film, the distance it is thrown onto the output screen is also greater than the tiny residual film, which makes it easier for the soil mixture to roll down along the output screen and fall from the screen hole to the ground, while the residual film is adsorbed on the output screen by electrostatic force and continues to be transported counterclockwise.
