[0002] At present, the mulching film planting technology has been widely used, which brings great benefits to agriculture, but the residual film in the soil also becomes a serious problem, which also brings great pollution and harm to the soil and environment. The soil is hindered by the growth of crops due to white pollution, and is seriously unable to provide for the crops.

[0032] Referring to the accompanying Figures 1-6 In the present application, a drum type residual film recycling device is disclosed, comprising a rack 7 and a pickup mechanism 1, an auxiliary film stripping mechanism 2, a turnover auxiliary impurity removal roller 3, an auger mechanism 5 and a film winding mechanism 6 connected to the rack 7. One end of the auxiliary film stripping mechanism 2 is located above the pickup mechanism 1 and cooperates with the pickup mechanism 1 with a gap, the other end abuts with the turnover auxiliary impurity removal roller 3, the end away from the auxiliary film stripping mechanism 2 of the turnover auxiliary impurity removal roller 3 cooperates with the auger mechanism 5 with a gap, and the film winding mechanism 6 is located below the turnover auxiliary impurity removal roller 3. The auxiliary film stripping mechanism 2 in the present application facilitates the separation of the pickup mechanism 1 and the picked-up ground film, and can separate the film and soil under the cooperation of the turnover auxiliary impurity removal roller 3. The separated soil and impurities are transported back to the field through the auger mechanism 5, and finally the film is wound through the film winding mechanism 6, greatly reducing the impurity content in the recycled film and improving the film recycling rate.

[0033] The pickup mechanism 1 comprises a pickup roller 11, both ends of which are rotatably connected to the rack 7, and the pickup roller 11 is driven to rotate clockwise by a motor. A plurality of rows of film lifting teeth 12 are uniformly arranged on the pickup roller 11, and the film lifting teeth 12 are used for recycling the film.

[0034] The auxiliary film stripping mechanism 2 comprises a plurality of auxiliary film stripping units and a connecting rod 24, both ends of the connecting rod 24 are fixedly connected to the rack 7, a plurality of auxiliary film stripping units are fixedly sleeved on the connecting rod 24, and a gap is provided between adjacent auxiliary film stripping units for accommodating the rotation of the film lifting teeth 12. The auxiliary film stripping unit comprises a support cover plate 21, one end of the support cover plate 21 is located above the pickup roller 11 and cooperates with the pickup roller 11 with a gap, the other end is provided with a circular arc groove matched with the turnover auxiliary impurity removal roller 3, the support cover plate 21 is circumferentially provided with a film stripping belt 23, and a support shaft 22 is rotatably connected inside the support cover plate 21 for supporting the film stripping belt 23.

[0035] The two ends of the turnover auxiliary cleaning roller 3 are rotatably connected to the frame 7, the turnover auxiliary cleaning roller 3 is located in the arc groove on the side close to the support cover plate 21, and abuts against the stripping belt 23 in the arc groove. One end of the pickup roller 11 is fixedly connected with a large chain wheel, and the same end of the turnover auxiliary cleaning roller 3 is fixedly connected with a small chain wheel. The large chain wheel and the small chain wheel are connected through an “8”-shaped chain (not shown in the figure). The clockwise rotation of the large chain wheel drives the counterclockwise rotation of the small chain wheel, that is, the clockwise rotation of the pickup roller 11 drives the counterclockwise rotation of the turnover auxiliary cleaning roller 3. Since the radius of the large chain wheel is greater than that of the small chain wheel, the angular velocity of the small chain wheel is greater than that of the large chain wheel, so that the angular velocity of the turnover auxiliary cleaning roller 3 is greater than that of the pickup roller 11. The counterclockwise rotation of the turnover auxiliary cleaning roller 3 drives the clockwise rotation of the stripping belt 23 in the arc groove, so that the linear velocity of the stripping belt 23 is greater than that of the film lifting teeth 12 in the pickup roller 11. Due to the greater linear velocity, the stripping belt 23 has a pulling effect on the mulch film by its own ductility, separates the mixture of the mulch film, the soil and the impurities from the film lifting teeth 12, and flattens the mulch film, which is transported along the arc surface to the turnover auxiliary cleaning roller 3.

[0036] The stirring mechanism 5 includes a main shaft 51, which is located on the side away from the support cover plate 21 of the turnover auxiliary cleaning roller 3. One end of the main shaft 51 is rotatably connected to one end of the frame 7, and the other end of the main shaft 51 extends out of the other end of the frame 7. The main shaft 51 is provided with a spiral blade 52. The soil and impurities falling into the stirring mechanism 5 are transported to the field under the action of the spiral blade 52 for recycling.

[0037] The film winding mechanism 6 includes two first film winding rollers 61 and two second film winding rollers 62. The two ends of the first film winding rollers 61 and the two ends of the second film winding rollers 62 are rotatably connected to the frame 7. The two first film winding rollers 61 are arranged in parallel below the turnover auxiliary cleaning roller 3, and are located at the same horizontal height and are jointly sleeved with a first film winding belt 63. The two second film winding rollers 62 are obliquely downwardly arranged on the side away from the pickup mechanism 1 of the first film winding rollers 61, and are jointly sleeved with a second film winding belt 64. The second film winding belt 64 is in clearance fit with the first film winding belt 63 and forms an included angle of 30-80°, so as to ensure that part of the mulch film hanging on the second film winding belt 64 can fall down, and the mulch film is wound at the included angle.

[0038] The first film winding belt 63 and the second film winding belt 64 are both provided with cleaning holes for separating the soil and impurities falling during the winding of the film.

[0039] The both sides of the guard plate 8 are fixedly connected to the rack 7, one end of the guard plate 8 is located between the turnover auxiliary cleaning roller 3 and the spiral blade 52, and the other end is located at the side of the second film winding roller 62 close to the spiral blade 52, for shielding the film winding mechanism and preventing the soil and impurities in the auger mechanism from falling into the film winding mechanism.

[0040] The soil scraping shovel 4 is also included, the both ends of the soil scraping shovel 4 are fixedly connected to the rack 7, the soil scraping shovel 4 is located between the guard plate 8 and the turnover auxiliary cleaning roller 3, and the side of the soil scraping shovel 4 close to the turnover auxiliary cleaning roller 3 is provided with a sharp end arc surface matched with the turnover auxiliary cleaning roller 3, for cleaning the impurities adhered to the turnover auxiliary cleaning roller 3.

[0041] The working principle of the present application is as follows: the pickup mechanism 1 picks up the mulch on the ground through the film lifting tooth 12, and rotates the mulch to the film stripping belt 23 in the auxiliary film stripping mechanism 2, the film stripping belt 23 has a pulling effect on the mulch due to the greater linear speed and the extensibility of the film stripping belt 23, the mixture of the mulch, soil and impurities is separated from the film lifting tooth, and the mulch is flattened and transported to the turnover auxiliary cleaning roller 3 along the arc surface, the turnover auxiliary cleaning roller 3 is extruded and matched with the film stripping belt 23 in the arc groove to transport the mulch to the film winding mechanism 6 below, part of the soil and impurities fall into the auger mechanism 5, and are transported to the field for recycling under the action of the spiral blade 52, and the mulch is wound at the angle between the second film winding belt 64 and the first film winding belt 63.
