[0014] The agricultural waste film recycling and regenerating device has the advantages that: When the agricultural waste film is recycled and regenerated and crushed, the connecting plate is pushed downward by the cooperation of the rotating groove in the interior of the fixed frame and the rotating rod, so that the position of the extruding roller at the bottom of the mounting frame is adjusted, and the soil clumps in the agricultural waste film can be crushed. Further, when the agricultural waste film is conveyed to the top end of the conveying belt, the motor at one end of the extruding roller is started to drive the extruding roller to rotate in the direction opposite to the moving direction of the conveying belt, so that the extruding roller rotates to the right when the conveying belt moves to the left. Further, when the agricultural waste film moves to the bottom end of the extruding roller, the spring is in a slight compression state to apply a stable pre-pressure to the extruding roller, the roller gap between the extruding roller and the conveying belt is fixed, small particle soil can be crushed, and the agricultural waste film can be flattened. Further, after the soil is crushed, the agricultural waste and old film will fall into the inside of the fixed box under the guidance of the guide plate. The crushing plate will reciprocate and hit in the inside of the fixed box. When the crushing plate reciprocates and hits, it will extrude the agricultural waste and old film when the agricultural waste and old film passes through the inside of the fixed box, so as to extrude and crush the soil blocks on the surface of the agricultural waste and old film, complete the secondary crushing work of the soil blocks on the surface of the agricultural waste and old film, so that the soil blocks fall off from the surface of the agricultural waste and old film, and the cleaning work of the soil on the surface of the agricultural waste and old film is completed. When the crushing plate reciprocates and hits, it will drive the cutting knife to move and cut the agricultural waste and old film into pieces, which is convenient for subsequent crushing. Further, after cutting, the agricultural waste and old film and the crushed soil will fall into the inside of the screening frame. The rotating shaft will drive the eccentric wheel to rotate in the rotating process. The eccentric wheel will drive one end of the screening frame to vibrate up and down in the rotating process, so that the agricultural waste and old film jumps up and down on the surface of the screening frame. At this time, the vibrating screening frame will screen the crushed soil in the agricultural waste and old film and fall into the collection box at the bottom end of the screening frame. Since the screening frame has a certain slope, the agricultural waste and old film at the top end of the screening frame will fall into the inside of the crushing box for crushing, so as to complete the recycling and crushing work of the agricultural waste and old film. By setting the auxiliary structure, the crushing roller will be high temperature in the process of crushing the agricultural waste and old film due to friction. The use of the eccentric annular air duct can make air flow in the inside of the eccentric annular air duct. When the eccentric annular air duct is set, the center point is offset to one side of the center point of the crushing roller, forming a wide air duct on one side close to the rotating shaft of the crushing roller and a narrow air duct on the other side close to the shell of the crushing roller. The centrifugal force will make the air in the inside of the eccentric annular air duct move to the side far from the rotating center. This side is close to the hot wall of the crushing roller, which is the roller shell generated by the friction of the film material. The air can be tightly attached to the hot wall to absorb heat, maximize the heat absorption of the hot wall of the crushing roller. The use of the spiral convex rib can make the spiral convex rib rotate synchronously with the roller body when the crushing roller rotates. The convex edge will grab the air in the air duct and push it forward along the spiral direction like an invisible hand. The air can only tightly adhere to the hot wall of the crushing roller to make spiral motion to prolong the contact time of the air and the hot wall and improve the heat absorption effect, that is, complete the heat dissipation work of the crushing roller, so that it is not easy to affect the service life due to high temperature in the process of long-time use. The air can also be heated to dry the agricultural waste and old film, which is a two-in-one effect. Further, the heat-exchanged air is discharged to the inside of the fixed box through the second air inlet seat. Since the second air inlet seat is provided with a second through hole on one side of the fixed box, the hot air discharged from the second air inlet seat can convect in the inside of the fixed box, so that the agricultural waste and old film can be preliminarily dried when passing through the inside of the fixed box. Further, the air outlet pipe also has a flow of air to the inside of the first air inlet seat when discharging air, and then blows to the first through hole. Since the first through hole is provided with two groups of air convection at the top of the screening frame, when the agricultural waste film jumps at the top of the screening frame, hot air can dry the agricultural waste film again, thereby completing multiple drying work of the agricultural waste film, and the agricultural waste film is better crushed in the subsequent crushing. The inside of one side of the first through hole and the second through hole is provided with a dust screen, which can intercept dust carried by air when the air passes through the agricultural waste film, prevent dust from flying during drying of the agricultural waste film, and complete the drying work of the agricultural waste film.

[0020] Specifically, in the present embodiment, when the agricultural waste film is recycled and crushed, the staff outputs the preliminarily treated agricultural waste film to the top end of the conveying belt 601 through the feeding machine. When the conveying belt 601 is working, the rotating rod 603 is rotated, and the rotating rod 603 is used in cooperation with the rotating groove in the fixed frame 602 to push the connecting plate 605 to move downward, thereby indirectly pushing the extrusion roller 609 at the bottom of the mounting frame 606 to move downward, so as to adjust the position of the extrusion roller 609 according to the crushing requirement, so that the extrusion roller 609 can crush the soil clumps in the agricultural waste film. When the agricultural waste film is conveyed to the top end of the conveying belt 601, the servo motor 6019 is started to move the conveying belt 601, and the servo motor 6019 is started at the same time to drive the extrusion roller 609 to rotate through the motor at one end of the extrusion roller 609. The rotating direction of the extrusion roller 609 is opposite to the moving direction of the conveying belt 601. For example, when the conveying belt 601 moves to the left, the extrusion roller 609 rotates to the right, so that the extrusion roller 609 can extrude the agricultural waste film. The core purpose is to make the friction direction of the extrusion roller 609 on the film consistent with the conveying direction of the conveying belt, so as to form an auxiliary driving force and avoid hindering the movement of the film. When the agricultural waste film moves to the bottom end of the extrusion roller 609, the spring 608 is in a slightly compressed state under the normal state, so as to apply a stable pre-pressure to the extrusion roller 609. At this time, the roller gap between the extrusion roller 609 and the conveying belt 601 is fixed, which can crush small particle soil and flatten the agricultural waste film. The rotating extrusion roller 609 can preliminarily crush the small particle soil in the agricultural waste film. When the extrusion roller 609 encounters large particle soil entering between the extrusion roller 609 and the conveying belt 601 during the crushing process, the large particle soil will generate an upward thrust on the extrusion roller 609. The thrust is greater than the pre-pressure of the spring 608, so that the spring 608 is further compressed, thereby driving the extrusion roller 609 and the mounting frame 606 to automatically rise in the vertical direction. The rising distance is equal to the height of the large particle, and the roller gap is expanded accordingly, so as to accommodate the large particle. During the compression process of the spring 608, the elastic reaction force of the spring 608 will increase with the increase of the deformation variable. The reaction force will be converted into the continuous extrusion force of the extrusion roller 609 on the large particle soil. As long as the spring 608 has a matching stiffness, even if the extrusion roller 609 rises, the extrusion force is still sufficient to crush the large particle soil clumps. After the large particle is crushed and conveyed out of the roller gap with the film material, the upward thrust disappears, the spring 608 returns to the original state, thereby driving the extrusion roller 609 to automatically descend back to the original position, the roller gap returns to the normal state, and the subsequent film material and small particles are continuously and stably extruded, so as to complete the preliminary crushing work of the large and small particle soil clumps in the agricultural waste film. The preliminary soil crushed agricultural waste film will fall into the inside of the fixed box 6010 under the guidance of the guide plate 6015, at this time the servo motor 6019 will drive the connecting disc 6020 to rotate through the belt after starting, the connecting disc 6020 will drive the rotating disc 6021 to rotate in the process of rotation, the rotating disc 6021 will drive the fixed column 6025 to rotate in the process of rotation, the fixed column 6025 will drive the moving rod 6023 to reciprocate in the inside of the guide sleeve 6024 through the cooperation of the connecting frame 6022 in the process of rotation, the moving rod 6023 will drive the crushing plate 6016 to reciprocate in the inside of the fixed box 6010 in the process of movement, the crushing plate 6016 will extrude the agricultural waste film when reciprocating, when the agricultural waste film passes through the inside of the fixed box 6010, so as to extrude the soil block on the surface of the agricultural waste film, the soil block on the surface of the agricultural waste film is crushed again, so that the soil block falls off from the surface of the agricultural waste film, the cleaning work of the soil on the surface of the agricultural waste film is completed, and the cutting knife 6017 will move to cut the agricultural waste film when the crushing plate 6016 reciprocates, so as to cut it into pieces, which is convenient for subsequent crushing, the agricultural waste film and the crushed soil after cutting will fall into the inside of the screening frame 6011, at this time the connecting disc 6020 will drive the rotating shaft 6013 to rotate through the belt in the process of rotation, the rotating shaft 6013 will drive the eccentric wheel 6014 to rotate in the process of rotation, the eccentric wheel 6014 will drive one end of the screening frame 6011 to vibrate up and down in the process of rotation, so that the agricultural waste film jumps up and down on the surface of the screening frame 6011, at this time the vibrating screening frame 6011 will screen the crushed soil in the agricultural waste film and fall into the collection box at the bottom end of the screening frame 6011, because the screening frame 6011 has a certain slope, so that the agricultural waste film at the top end of the screening frame 6011 will fall into the inside of the crushing box 3 for crushing, so as to complete the soil cleaning work on the surface of the agricultural waste film.

[0021] Referring to Figures 6-13The inside of the pulverizing box 3 is internally provided with a pulverizing roller 4, the inside of the pulverizing roller 4 is provided with an auxiliary structure 7, the auxiliary structure 7 comprises an eccentric ring air duct 701, the eccentric ring air duct 701 is arranged on one side of the central axis of the pulverizing roller 4, the inside of the pulverizing roller 4 is fixedly provided with a fixed shaft 703, one end of the fixed shaft 703 is rotatably and sealingly connected with one end of the air inlet pipe 2, the other end of the fixed shaft 703 is rotatably and sealingly connected with an air outlet pipe 709, one side of the inside of the eccentric ring air duct 701 is provided with a spiral convex rib 702, one side of the one end of the fixed shaft 703 is provided with an air inlet 704, one side of the other end of the fixed shaft 703 is provided with an air outlet 705; one end of the air outlet pipe 709 is provided with a connecting pipe 7010, one end of the connecting pipe 7010 is provided with a second air inlet seat 7011, the second air inlet seat 7011 is arranged on one side of a fixed box 6010, both sides of the fixed box 6010 are provided with second through holes 7012, the other end of the air outlet pipe 709 is provided with a first air inlet seat 706, the first air inlet seat 706 is arranged on one side of a screening frame 6011, both sides of the top end of the screening frame 6011 are provided with first through holes 707, the first through holes 707 and the second through holes 7012 are uniformly provided with dustproof nets 708 on one side of the inside; the first through holes 707 are provided in multiple groups, the multiple groups of the first through holes 707 are symmetrically distributed in the inside of the top end of the screening frame 6011; the spiral convex ribs 702 are provided in multiple groups, the multiple groups of the spiral convex ribs 702 are equidistantly arranged on one side of the inside of the eccentric ring air duct 701.

[0022] Specifically, in the present embodiment, when the pulverizing box 3 is pulverizing, the motor is started to drive the two sets of pulverizing rollers 4 to rotate, thereby completing the pulverizing work of the agricultural waste film. During the pulverizing process of the agricultural waste film, the pulverizing rollers 4 will be high temperature due to friction. At this time, the air inlet pipe 2 is externally connected to the air blower, so that air is blown to the inside of the fixed shaft 703 through the air inlet pipe 2, and then blown to the inside of the eccentric annular air duct 701 through the air inlet 704. The eccentric annular air duct 701 is arranged with the center point offset to one side of the center point of the pulverizing roller 4, forming a wide air duct on one side close to the center axis of the pulverizing roller 4 and a narrow air duct on the other side close to the shell of the pulverizing roller 4. The air is thrown by the centrifugal force. The pulverizing roller 4 generates centrifugal force during self-rotation, which can throw the air in the eccentric annular air duct 701 to the side farther from the rotation center, that is, the narrow air duct. This side is just close to the hot wall of the pulverizing roller 4, which is the roller shell generated by the friction of the film material. The air can be tightly attached to the hot wall to absorb heat, and the use of the spiral protruding rib 702 can make the spiral protruding rib 702 rotate synchronously with the roller body during the self-rotation of the pulverizing roller 4. The protruding edge will grab the air in the air duct and push it forward along the spiral direction like an invisible hand, forcing the air to move in a spiral motion close to the hot wall of the pulverizing roller 4 to prolong the contact time of the air and the hot wall and improve the heat absorption effect, that is, to complete the heat dissipation work of the pulverizing roller 4, so that it is not easy to affect the service life due to high temperature during long-term use. Also, the air can be heated, so that hot air can dry the agricultural waste film. It is a hit and a win. The air after heat exchange is discharged through the air outlet 705 and discharged into the inside of the air outlet pipe 709. Then the air in the inside of the air outlet pipe 709 is discharged into the inside of the fixed box 6010 through the second air inlet seat 7011 at one end of the connecting pipe 7010. Since the second air inlet seat 7011 is arranged with the second through hole 7012 on one side of the fixed box 6010, the hot air discharged from the second air inlet seat 7011 can be convection in the inside of the fixed box 6010, so that the agricultural waste film can be preliminarily dried when passing through the inside of the fixed box 6010. The air outlet pipe 709 also has a way of air flowing into the inside of the first air inlet seat 706 when discharging air, and then blowing to the first through hole 707. Since the first through hole 707 is arranged with two sets of air convection at the top of the screening frame 6011, the hot air can dry the agricultural waste film again when the agricultural waste film jumps at the top of the screening frame 6011, thereby completing the multiple drying work of the agricultural waste film, so that the agricultural waste film is better in subsequent pulverizing. The inside of the first through hole 707 and the second through hole 7012 are both arranged with 708 dust screens, so that the dust carried by the air can be intercepted when the air passes through the agricultural waste film, preventing the dust from flying during the drying of the agricultural waste film. The dried agricultural waste film will fall into the inside of the pulverizing box 3 for pulverizing and recycling.Finally, the recycling of agricultural waste film is completed.
