[0002] The current agricultural mulch film is a film made of polyethylene. The thickness of my country's mulch film is generally thicker, which is the result of the development of the plastic industry. Agricultural mulch films are mostly used in agricultural production. They play a very important role in moisture retention and heat preservation during the sowing period of agricultural production. They have greatly changed the growth environment of crops and the agricultural planting model, allowing some crops that were originally unable to be planted or had low planting benefits in plateau areas to grow well. Therefore, they are widely used in agricultural production in agricultural countries such as my country. However, due to the polyethylene material of agricultural mulch films, the mulch films left in the land will cause a lot of harm to the cultivated land environment and agricultural crops, and the use area of ​​mulch films is large, so the used mulch films need to be recycled and reused. At present, in the recycling process, the pressed blocks on the mulch films need to be cleaned first, and then the mulch films are wound onto the winding shaft for recycling.

[0031] See also Figure 1 and Figure 8 A device for recycling and reusing agricultural mulch film comprises a U-shaped frame 1, a walking roller 2, a cleaning mechanism 3, a cleaning mechanism 4 and a winding mechanism 5. The front and rear end surfaces of the U-shaped frame 1 are rotatably connected with two walking rollers 2 arranged symmetrically on the left and right sides. The left end surfaces of the two vertical sections of the U-shaped frame 1 are jointly provided with the cleaning mechanism 3. The cleaning mechanism 4 and the winding mechanism 5 are sequentially provided between the two vertical sections of the U-shaped frame 1 from left to right.

[0032] See also Figure 1 , Figure 2 , Figure 6 and Figure 8The cleaning mechanism 3 includes a mounting plate 30, a rotating shaft 31, a placement plate 32, a cleaning shaft 33 and a cleaning roller 330. The left end surfaces of the two vertical sections of the U-shaped frame 1 are fixedly connected with mounting units. The mounting units are two mounting plates 30 symmetrically arranged up and down. The front section between the two mounting plates 30 in the same mounting unit is rotatably connected with the rotating shaft 31. The rotating shaft 31 is fixedly connected with two placement plates 32 symmetrically arranged up and down, and the placement plates 32 are both located between the corresponding two mounting plates 30. The cleaning shaft 33 is rotatably connected between the corresponding upper and lower placement plates 32, and the cleaning shaft 33 passes through the corresponding upper placement plate 32. A cleaning roller 330 is fixedly sleeved on the cleaning shaft 33. The circumferential outer wall of the cleaning roller 330 is provided with rigid plates 331 and cleaning brushes 332 uniformly and staggeredly distributed along its circumference, and the rigid plates 331 and the cleaning brushes 332 are staggered. The length of the cleaning brush 332 is greater than the length of the rigid plates 331. The two opposite surfaces of the mounting plate 30 are commonly fixedly connected with a placement bar 34, and the upper end surface of the placement bar 34 is provided with two front-to-rear symmetrical rotating shafts 340, and the rotating shaft 340 and the placement bar 34 are rotationally connected, and the rear side of the rotating shaft 340 located at the rear is provided with an arc-shaped motor seat 35 fixedly connected to the placement bar 34, and a cleaning motor 350 is fixedly provided on the arc-shaped motor seat 35, and the output shaft of the cleaning motor 350 is fixedly connected to the rotating shaft 340 adjacent to the arc-shaped motor seat 35, and the upper end surface of the rear placement plate 32 is rotationally connected with a matching shaft 320, and the matching shaft 320 is located on the right side of the cleaning shaft 33 on the placement plate 32, and a matching gear 321 is fixedly sleeved on the matching shaft 320, and a cleaning gear 333 is fixedly sleeved on the cleaning shaft 33 adjacent to the matching shaft 320, and the two are meshed with each other, and the matching shaft 320, the two rotating shafts 340 and the front cleaning shaft 33 are matched with the cleaning belt 36 through the pulleys on each of them.

[0033] When working, the U-shaped frame 1 is pushed, and the cleaning roller 330 in the cleaning mechanism 3 is located at one end of the agricultural mulch film to be recycled through the rolling of the walking roller 2. The cleaning motor 350 works, and its output shaft drives the rotating shaft 340 below to rotate counterclockwise. The front rotating shaft 340, the cleaning shaft 33 and the matching shaft 320 are driven counterclockwise through the cleaning belt 36, so that the front cleaning roller 330 rotates counterclockwise, and the matching shaft 320 is meshed with the cleaning gear 333 on the rear cleaning shaft 33 through the matching gear 321 thereon, driving the cleaning shaft 33 to rotate clockwise, so that the rear cleaning roller 330 rotates clockwise. When the cleaning roller 330 rotates, It drives the rigid plate 331 and the cleaning brush 332 arranged thereon to rotate. When the rigid plate 331 contacts the pressing block above the agricultural mulch film 7, when the material of the pressing block is soil, the rigid plate 331 sweeps the pressing block to both sides of the mulch film 7 to break it, and the cleaning brush 332 cleans the soil remaining on the mulch film 7 out of the surface of the mulch film 7. When the material of the pressing block is a material that is not easy to break, it is mainly swept away by the rigid plate 331 so that it has no pressing effect on the mulch film 7. The front cleaning roller 330 is controlled to turn counterclockwise and the rear cleaning roller 330 is controlled to turn clockwise, and the device is pushed during the working process, so that the pressing blocks on the mulch film 7 that play a pressing role are pushed to both sides or broken and cleaned.

[0034] See also Figure 1 and Figure 5 The right ends of the corresponding upper and lower placement plates 32 are fixedly connected with a connecting block 334, and the right end face of the connecting block 334 is fixedly connected with a rotating rod 335. A vertical plate 336 located on the right side of the connecting block 334 is arranged between the adjacent upper and lower mounting plates 30, and a circular arc plate 337 symmetrically arranged up and down is arranged on the front end face of the vertical plate 336.

[0035] During operation, the left cleaning roller 330 is rotated along the axial direction of the cleaning shaft 33 by rotating the rotating rod 335. When the required angular position is reached, the rotating rod 335 is positioned by inserting the positioning pin 37 into a through hole 339 and its corresponding positioning hole 338 on the rotating rod 335, so that the left cleaning roller 330 is positioned. The cooperation of the through hole 339 and the positioning hole 338 on the rotating rod 335 enables the two cleaning rollers 330 to clean the pressure blocks at different positions, and the staggered positioning holes 338 can perform positioning restrictions when the cleaning roller 330 swings at a smaller angle.

[0036] See also Figure 1 and Figure 6 A spring plate 341 is provided on the left end face of the placement bar 34, and two upper and lower symmetrical limiting plates 342 are provided on the left end face of the spring plate 341. A moving groove 343 is opened on the limiting plate 342, and a moving shaft 344 is slidably connected in the two moving grooves 343. A clamping shaft 345 is fixedly sleeved on the moving shaft 344, and the right side of the clamping shaft 345 is tightly attached to the cleaning belt 36.

[0037] During operation, when the cleaning roller 330 swings to the corresponding two sides, the cleaning belt 36 drives the clamping shaft 345 to move to the left, and the clamping shaft 345 makes the movable shaft 344 slide in the movable groove 343, so the clamping plate 346 moves to the left to stretch the reset spring 347, and when the two cleaning rollers 330 rotate in opposite directions, the reset spring 347 resets, and the clamping plate 346 moves to the right under the action of elastic force, so that the clamping shaft 345 drives the cleaning belt 36 to move to the right, so through the cooperation between the reset spring 347 and the clamping shaft 345, after the cleaning roller 330 swings to adjust its position, the cleaning belt 36 is tightened to avoid the problem of the cleaning belt 36 loosening and affecting the rotation of the cleaning roller 330.

[0038] See also Figure 1 , Figure 3 , Figure 7 , Fig. 9 and Fig.10The cleaning mechanism 4 includes a right-angle plate 40, a cleaning shaft 41, a rotating cleaning shaft 42 and a matching belt 43. The left end face of the vertical section of the U-shaped frame 1 is fixedly connected with the right-angle plate 40. The opposite surfaces of the two vertical sections of the U-shaped frame 1 are rotatably connected with two cleaning shafts 41 arranged from left to right. A rotating cleaning shaft 42 rotatably connected to the U-shaped frame 1 is arranged above the middle position of the two cleaning shafts 41 in the horizontal direction, and the rotating cleaning shaft 42 runs through the vertical section in front of the U-shaped frame 1. The front end of the rotating cleaning shaft 42 cooperates with the output end of the winding motor 540 in the winding mechanism 5 through the matching belt 43. A cleaning roller 420 is fixedly sleeved on the rotating cleaning shaft 42. The circumferential outer wall of the cleaning roller 420 is provided with brushes 421 evenly distributed along its circumference for cleaning the ground film 7, and the opposite surface of the vertical section of the U-shaped frame 1 is provided with a lifting groove 44 facing the U-shaped frame 1, and a collecting box 45 is provided between the two lifting grooves 44, and the front and rear end surfaces of the collecting box 45 are provided with lifting blocks 450 that slidably cooperate with the lifting grooves 44, and the collecting box 45 is located on the left side of the cleaning roller 420. The collecting box 45 is a cavity structure with an arc-shaped right end surface, and the arc-shaped section of the collecting box 45 is provided with an opening, and the opening cooperates with the cleaning roller 420, and an arc-shaped rubber baffle 451 made of elastic rubber material is fixedly connected to the upper end surface of the opening of the collecting box 45.

[0039] During operation, when the agricultural mulch film 7 is wound and recovered, the winding motor 540 in the winding mechanism 5 is operated, and the cleaning roller 420 on the rotating cleaning shaft 42 is driven to rotate clockwise by cooperating with the belt 43. Therefore, the brush 421 on the cleaning roller 420 cleans the upper surface of the mulch film 7 passing under the rotating cleaning shaft 42, and sweeps most of the debris and soil attached to the mulch film 7 into the collecting box 45. The rubber baffle 451 in the collecting box 45 blocks the debris and soil swept into the collecting box 45 to prevent the collected debris and soil from returning to the mulch film 7 and affecting the cleaning effect. The two cleaning shafts 41 control the tension and height of the ground film 7 when winding the ground film 7, so that the ground film 7 is in close contact with the cleaning roller 420, ensuring the cleaning effect of the cleaning roller 420. When a large amount of debris and soil are collected in the collecting box 45, the collecting box 45 is taken out through the cooperation of the pulling groove 44 and the collecting box 45 to clean the collecting box 45. In the process of the movement of the device, because the soil on the land covered with the ground film 7 is relatively moist, it will adhere to the ground film 7. The two right-angle plates 40 shovel the ground film 7 on the land during the movement to prevent it from breaking during the recycling process.

[0040] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6The opposite surfaces of the two vertical sections of the U-shaped frame 1 are fixedly connected with a scraper 46 , which is located below the cleaning roller 420 . The scraper 46 is an arc-shaped structure, and the upper arc surface of the scraper 46 is in close contact with the ground film 7 .

[0041] During operation, since the lower surface of the agricultural film 7 is generally in contact with the land for a long time, a large amount of soil clods and debris will be attached to it. When the agricultural film 7 is rolled up, the scraper 46 scrapes and cleans the lower surface of the film 7, scraping off a large amount of soil clods and debris and making them fall onto the land.

[0042] See also Fig.10 A water tank 47 with an upper opening is provided between the vertical sections of the U-shaped frame 1. The water tank 47 is located at the right lower side of the right cleaning shaft 41. Two cleaning shafts 470 are symmetrically distributed and rotatably connected to the vertical section of the U-shaped frame 1. The two cleaning shafts 470 are lower than the two ends of the water tank 47. A strip-shaped cleaning sponge 471 is provided on the lower end surface of the inner cavity of the water tank 47, and the upper end of the cleaning sponge 471 is flush with the lower end of the cleaning shaft 470. Two mutually connected pieces are provided at the right position of the right cleaning shaft 470 between the vertical sections of the U-shaped frame 1.

[0043] During operation, clean water is placed in the water tank 47, and the two cleaning shafts 470 cooperate with each other to press the ground film 7 into the clean water. During the winding process of the ground film 7, the cleaning sponge 471 below cleans the lower surface of the ground film 7. The ground film 7 cleaned in the clean water enters the cooperation between the right cleaning shaft 470 and the matching rotating shaft 49 so that it passes between the two inclined plates 48, and the moisture on the two surfaces of the ground film 7 is absorbed by the water-absorbing sponge 482 on the two inclined plates 48. When the water absorption effect of the water-absorbing sponge 482 is poor, the trapezoidal slider 481 is taken out at the rear end face of the U-shaped frame 1 through the cooperation between the trapezoidal groove 480 and the trapezoidal slider 481, and the water-absorbing sponge 482 is cleaned or replaced.

The front end surface of the triangular plate 53 on the front side is fixedly connected with the front end surface of the U-shaped frame 1 to have two U-shaped blocks 530 arranged symmetrically on the left and right. The rear end surface of the triangular plate 53 on the rear side is fixedly connected with the rear end surface of the U-shaped frame 1 to have two U-shaped blocks 530 arranged symmetrically on the left and right. The front end surface of the U-shaped frame 1 is fixedly connected with a motor seat 54. The motor seat 54 is fixedly connected with a winding motor 540, and the axial direction of the output shaft of the winding motor 540 is located at the slanted lower opening 51. A winding shaft 6 is arranged at the intersection with the upper oblique opening 52 and at the intersection with the lower oblique opening 51 and the upper oblique opening 52. The output shaft fixing sleeve of the winding motor 540 is provided with a winding sleeve 541 which matches the winding shaft 6. The circumferential outer wall of the winding sleeve 541 is provided with a groove 542 which leads to the center of the winding sleeve 541 and is wider than the winding shaft 6. The rear end face of the winding sleeve 541 is provided with a T-shaped groove 543 which is symmetrical along the center of its cross-section circle, and the vertical section of the T-shaped groove 543 is connected with the groove 542. A T-shaped block 544 which slides along its vertical section is arranged in the T-shaped groove 543, and a top spring 545 is arranged between the horizontal section of the T-shaped block 544 and the horizontal section of the T-shaped groove 543. The circumferential outer wall of the winding shaft 6 close to the end face is provided with an even number of right-angled trapezoidal grooves 60 evenly distributed along its circumference, and the hypotenuse of the right-angled trapezoidal groove 60 is close to the end face of the winding shaft 6.

[0045] During operation, the winding shaft 6 is placed on the horizontal opening 50, and the end of the winding shaft 6 with the trapezoidal groove 480 is placed on the front side, so that it rolls down from the oblique lower opening 51 to the junction of the oblique lower opening 51 and the oblique upper opening 52. The winding shaft 6 is manually pushed from the rear to make the front end of the winding shaft 6 press against the inside of the winding sleeve 541, the T-shaped block 544 contacts the circumferential surface of the winding shaft 6, the top spring 545 is compressed, and the winding shaft 6 is rotated so that the right-angled trapezoidal groove 60 of the winding shaft 6 cooperates with the T-shaped block 544. When the T-shaped block 544 is facing the right-angled trapezoidal groove 60, the top spring 545 is reset, and the vertical section of the T-shaped block 544 is locked in under the elastic force of the top spring 545. In the right-angled trapezoidal groove 60, the winding motor 540 drives the winding sleeve 541 on its output shaft to rotate clockwise, so the winding shaft 6 winds and collects the ground film 7 wound thereon. When there is too much ground film 7 collected on the winding shaft 6, the winding shaft 6 is manually pulled from the rear, and the vertical section of the T-shaped block 544 contacts the inclined surface of the right-angled trapezoidal groove 60. The T-shaped block 544 compresses the top spring 545 to take out the winding shaft 6, and the top spring 545 is reset. The special shape of the right-angled trapezoidal groove 60 facilitates the removal of the winding shaft 6 and the circumferential limitation of the winding shaft 6 during rotation. The winding shaft 6 wound with the ground film 7 is taken out through the inclined upper opening 52 for recycling or other treatment.

[0046] See also Figure 1 , Figure 4 and Fig.10 A through slot 531 penetrating the triangular plate 53 is provided on the left upper end surface of the triangular plate 53, a shaft blocking pin 532 is slidably arranged in the through slot 531, and a shaft blocking spring 533 is arranged between the lower end surface of the round cap of the shaft blocking pin 532 and the corresponding upper end surface of the triangular plate 53.

[0047] During operation, multiple winding shafts 6 are placed on the horizontal opening 50. When the previous winding shaft 6 finishes winding and collecting the ground film 7 and is taken out, the two blocking shaft pins 532 are pulled upwards. The blocking shaft pins 532 stretch the blocking shaft springs 533, and at the same time, the lower ends thereof are recovered into the through grooves 531 from the oblique lower opening 51, so that the wound winding shaft 6 rolls to the bottom to wait for the winding operation. The blocking shaft pins 532 are released, the blocking shaft springs 533 are reset, and the blocking shaft pins 532 are reset under the action of elastic force, and continue to block the winding shaft 6 in the horizontal opening 50.

[0048] In addition, the present invention also provides a method for recycling and reusing agricultural mulch film, comprising the following steps: S1, cleaning blocks: the cleaning motor 350 works, and the front rotating shaft 340, the cleaning shaft 33 and the matching shaft 320 rotate counterclockwise through the cleaning belt 36, so that the front cleaning roller 330 rotates counterclockwise, and the matching shaft 320 is meshed with the cleaning gear 333 on the rear cleaning shaft 33 through the matching gear 321 thereon, driving the cleaning shaft 33 to rotate clockwise, so that the rear cleaning roller 330 rotates clockwise, and when the cleaning roller 330 rotates, it drives the rigid plate 331 and the cleaning brush 332 arranged thereon to rotate, and pushes the device during the working process, thereby pushing the blocks that play a pressing role on the mulch film 7 to both sides or breaking and cleaning them.

[0049] S2. Winding the ground film: manually push the winding shaft 6 from the rear so that the front end of the winding shaft 6 is pressed tightly against the winding sleeve 541, the T-shaped block 544 contacts the circumferential surface of the winding shaft 6, the top spring 545 is compressed, and the winding shaft 6 is rotated so that the right-angled trapezoidal groove 60 of the winding shaft 6 cooperates with the T-shaped block 544. When the T-shaped block 544 is directly opposite to the right-angled trapezoidal groove 60, the top spring 545 is reset, and the vertical section of the T-shaped block 544 is stuck in the right-angled trapezoidal groove 60 under the elastic force of the top spring 545. After cleaning a section of the ground film 7 above the pressure block at one end of the ground film 7 by the cleaning mechanism 3, the ground film 7 is manually passed through two cleaning shafts 41, two cleaning shafts 470 and one matching shaft to the installed winding shaft 6.

[0050] S3. Cleaning the ground film: After the ground film 7 is wound up, the collecting box 45 is put down, and the winding motor 540 is started to wind the ground film 7, thereby driving the cleaning roller 420 on the rotating cleaning shaft 42 to rotate clockwise through the matching belt 43. Therefore, the brush 421 on the cleaning roller 420 cleans the upper surface of the ground film 7 passing under the rotating cleaning shaft 42, and sweeps most of the debris and soil attached to the ground film 7 into the collecting box 45, and the cleaning sponge 471 below cleans the lower surface of the ground film 7. The ground film 7 cleaned in the clean water enters the matching between the right cleaning shaft 470 and the matching shaft 320, so that it passes between the two oblique plates 48, and the moisture on the two surfaces of the ground film 7 is absorbed by the water-absorbing sponge 482 on the two oblique plates 48.

[0051] S4. Recovering the ground film: After the ground film 7 is cleaned, the device is moved along the placement direction of the ground film 7 under manual push, and a large amount of ground film 7 is wound on the winding shaft 6. The winding shaft 6 is manually pulled from the rear, and the vertical section of the T-block 544 contacts the inclined surface of the right-angle trapezoidal groove 60. The T-block 544 compresses the top spring 545, and the winding shaft 6 wound with the ground film 7 is taken out through the inclined upper opening 52 for recovery or other treatment.
