DETAILED DESCRIPTION

[0032] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] The embodiment of the present invention provides a waste agricultural film recycling and processing device, such as Figure 1-14 As shown, the waste agricultural film recycling and processing device includes: an equipment frame 1, a separation box 2 and a crushing box 3, the separation box 2 is fixedly installed on the equipment frame 1, the crushing box 3 is fixedly installed on the top of the separation box 2, and the crushing box 3 is connected to the separation box 2 so that the crushed agricultural film material falls into the separation box 2; two crushing rollers 4 are rotatably installed in the crushing box 3, and the two crushing rollers 4 are meshed with each other to crush the agricultural film material. The same end of the input shaft of the two crushing rollers 4 is fixedly sleeved with a synchronous gear 5, and the two synchronous gears 5 are meshed with each other. A driving motor 6 located on the side of the crushing box 3 is fixedly installed on the separation box 2. A pulley 7 is fixedly mounted on the output shaft of the driving motor 6 and the input shaft of one of the crushing rollers 4. The two pulleys 7 are mounted with the same synchronous belt 8 so that the driving motor 6 drives the two crushing rollers 4 to rotate; a waste outlet 9 is provided at the bottom of the separation box 2, and a separation net 10 is provided in the waste outlet 9 for separating the crushed agricultural film material and impurities; a secondary crushing mechanism is connected to the separation box 2 for secondary crushing of the screened agricultural film material.

[0034] In this embodiment, the waste agricultural film recycling process consists of two main stages: crushing and separation. First, the waste agricultural film is placed into the crushing box 3. The drive motor 6 is activated, driving the two crushing rollers 4 via pulley 7 and synchronous belt 8. Because the input shafts of the two crushing rollers 4 are fixedly mounted with meshing synchronous gears 5, the two crushing rollers 4 can rotate in opposite directions, initially crushing the waste agricultural film. The crushed material then flows through the connection between the crushing box 3 and the separation box 2 and falls into the separation box 2. Within the separation box 2, the crushed material is screened by a separation screen 10. Impurities are discharged through the waste outlet 9, while material that meets size requirements remains in the separation box 2. Finally, a secondary crushing mechanism connected to the separation box 2 performs a secondary crushing on the screened material, further improving the crushing efficiency and meeting the requirements for subsequent recycling.

[0035] This device, through the provision of two meshing crushing rollers 4 and a transmission structure with synchronous gears 5, achieves efficient crushing of waste agricultural film. Simultaneously, the separation net 10 within the separation box 2 effectively separates the crushed material from impurities, reducing manual screening operations during subsequent processing and improving recycling efficiency. Furthermore, the provision of a secondary crushing mechanism further optimizes the crushing effect, resulting in a more uniform size of the crushed material, which is more conducive to subsequent recycling and processing, thereby increasing the recycling rate of waste agricultural film.

[0036] This device effectively solves the problems of poor crushing effect and difficulty in impurity separation during the recycling and treatment of waste agricultural films through reasonable structural design and transmission mode.

[0037] In a further preferred embodiment of the present invention, the secondary crushing mechanism includes a crushing drum 11 arranged at the bottom of the separation box 2, the bottom of the crushing drum 11 is open, and the crushing drum 11 is arranged to avoid the waste outlet 9. A venturi tube 12 is fixedly installed on the side of the crushing drum 11, and the discharge end of the venturi tube 12 is connected to the crushing drum 11. A suction pipe 13 is fixedly installed on the neck of the venturi tube 12, and the feed end of the suction pipe 13 is connected to the separation box 2 for sucking out the material, and a discharge shaft 14 is rotatably installed in the crushing drum 11, and an auger blade 15 is fixedly sleeved on the discharge shaft 14. The top of the auger blade 15 corresponds to the discharge end of the venturi tube 12 for receiving the material and transmitting it downward, and a plurality of movable blades 16 are fixedly installed on the bottom end of the discharge shaft 14, and a plurality of fixed blades 17 are fixedly installed on the lower inner wall of the crushing drum 11. The fixed blades 17 are engaged with the movable blades 16 for crushing the material.

[0038] In this embodiment, the secondary crushing mechanism further optimizes the recycling process for waste agricultural film. After initial crushing and screening, the material is drawn into the venturi tube 12 through the suction pipe 13 and fed into the crushing drum 11 from the discharge end of the venturi tube 12. Auger blades 15 are fixedly mounted on the discharge shaft 14 within the crushing drum 11. These auger blades 15 pick up the material and convey it downward to the bottom of the crushing drum 11. At this point, the multiple moving blades 16 at the bottom of the discharge shaft 14 engage with fixed blades 17 on the lower inner wall of the crushing drum 11, performing a secondary crushing of the material. The crushed material is discharged through an opening at the bottom of the crushing drum 11, completing the secondary crushing process.

[0039] This embodiment, through the provision of a venturi tube 12 and a suction pipe 13, effectively and automatically draws separated material into the crushing drum 11, reducing manual operation and improving automation. Furthermore, the coordination of the auger blades 15, the moving blades 16, and the fixed blades 17 within the crushing drum 11 further enhances the crushing effect, making the material size more uniform and further reducing the difficulty of subsequent processing. Furthermore, the crushing drum 11 is positioned away from the waste outlet 9.

[0040] In this embodiment, the auger blades 15 play a crucial role. After initial crushing and screening, the material is drawn into the venturi tube 12 through the suction pipe 13 and fed into the crushing drum 11 from the discharge end of the venturi tube 12. At this point, the auger blades 15, driven by the discharge shaft 14, rotate, picking up the material and conveying it downward along the spiral direction of the blades to the bottom of the crushing drum 11. During this process, the auger blades 15 not only convey the material but also provide preliminary compression and alignment, ensuring a more even distribution of the material into the secondary crushing zone, thus providing better conditions for the subsequent crushing operations by the moving blades 16 and fixed blades 17.

[0041] In a further preferred embodiment of the present invention, a V-shaped dividing plate 18 is fixedly installed on the bottom inner wall of the separation box 2. The V-shaped dividing plate 18 is inverted with the tip facing upward. Its setting position corresponds to between the two crushing rollers 4 and is used to separate materials to both sides. Two waste outlets 9 and separation nets 10 are provided, which are respectively located on both sides of the V-shaped dividing plate 18, and the crushing cylinder 11 is located directly below the V-shaped dividing plate 18.

[0042] In this embodiment, the waste agricultural film recycling and processing device optimizes the separation and transmission process of materials by fixing an inverted V-shaped dividing plate 18 on the bottom inner wall of the separation box 2. After the waste agricultural film is crushed by the crushing roller 4, the material falls into the separation box 2. The tip of the V-shaped dividing plate 18 faces upward, and the setting position corresponds to the position between the two crushing rollers 4, which can separate the crushed materials evenly to both sides. The bottom of the separation box 2 is provided with two waste outlets 9 and two separation nets 10, which are respectively located on both sides of the V-shaped dividing plate 18, for separating materials and impurities. The material screened by the separation net 10 is sucked into the venturi tube 12 through the suction pipe 13, and is sent to the crushing cylinder 11 located directly below the V-shaped dividing plate 18 for secondary crushing.

[0043] The V-shaped separator 18 further improves the separation and transport of waste agricultural film. First, it evenly distributes the crushed material to both sides of the separation box 2, preventing accumulation and improving separation efficiency. Second, the design of the two waste outlets 9 and the two separation screens 10 allows for more efficient separation of impurities and material.

[0044] In a further preferred embodiment of the present invention, two Venturi tubes 12 and two suction pipes 13 are provided, and the two Venturi tubes 12 are respectively located on the corresponding sides of the crushing cylinder 11, and the two suction pipes 13 are respectively connected to the corresponding sides of the separation box 2 and are arranged corresponding to the waste outlet 9.

[0045] In this embodiment, the waste agricultural film recycling and processing device further optimizes the material transfer process by providing two Venturi tubes 12 and two suction tubes 13. Specifically, the two Venturi tubes 12 are located on corresponding sides of the crushing drum 11, while the two suction tubes 13 are connected to corresponding sides of the separation box 2 and are arranged corresponding to the waste outlet 9. After preliminary crushing and screening, the material is sucked into the two Venturi tubes 12 through the two suction tubes 13 and delivered into the crushing drum 11 from the discharge end of the Venturi tubes 12. This dual-channel design allows material to be sucked in from both sides of the separation box 2 simultaneously, avoiding the problems of material accumulation and poor transfer that may occur with a single channel.

[0046] Secondly, the two suction pipes 13, positioned corresponding to the waste outlet 9, more effectively aspirate the screened material. Since the suction pipes 13 are positioned higher than the waste outlet 9, they prevent impurities from entering the crushing drum 11, further improving the purity of the material. Furthermore, the discharge ends of the two venturi tubes 12 are respectively connected to the crushing drum 11, evenly feeding the material into the crushing drum 11. This provides better conditions for secondary crushing and further enhances the crushing effect.

[0047] In a further preferred embodiment of the present invention, a shaft plate 19 is fixedly installed at the bottom of the separation box 2, and a power transmission shaft 20 is rotatably installed on the shaft plate 19. The power transmission shaft 20 and the input shaft of one of the crushing rollers 4 are fixedly sleeved with a pulley 21, and the two pulleys 21 are sleeved with the same synchronous belt 22, so that the crushing roller 4 drives the power transmission shaft 20 to rotate, and the top of the power transmission shaft 20 and the discharge shaft 14 are fixedly sleeved with a bevel gear 23, and the two bevel gears 23 are engaged with each other, so that the power transmission shaft 20 drives the discharge shaft 14 to rotate.

[0048] In this embodiment, the power transmission system of the waste agricultural film recycling and processing device achieves power linkage between the crushing roller 4 and the discharge shaft 14 through a shaft plate 19, a power transmission shaft 20, a second pulley 21, and a second synchronous belt 22. Specifically, a shaft plate 19 is fixedly mounted on the bottom of the separation box 2, and the power transmission shaft 20 is rotatably mounted on the shaft plate 19. A second pulley 21 is fixedly mounted on the power transmission shaft 20 and the input shaft of one of the crushing rollers 4. The two pulleys 21 are connected by a second synchronous belt 22. When the crushing roller 4 rotates, its power is transmitted to the power transmission shaft 20 via the second pulley 21 and the second synchronous belt 22. A bevel gear 1 23 is fixedly mounted on the top of the power transmission shaft 20. A bevel gear 1 23 is also fixedly mounted on the top of the discharge shaft 14. The two bevel gears 1 23 mesh together, allowing the power transmission shaft 20 to drive the discharge shaft 14 to rotate, thereby driving the auger blades 15 and the moving blade 16 to operate, completing the material transfer and secondary crushing.

[0049] In a further preferred embodiment of the present invention, the inlet ends of the two venturi tubes 12 are both closed ends, on which a fan shaft 28 is rotatably mounted, and an air inlet 30 with a filter is also provided. The fan shaft 28 has fan blades so that when the fan shaft 28 rotates, the fan blades on it inhale air through the air inlet 30 with the filter and discharge it to the discharge end of the venturi tube 12. The inlet ends of the two venturi tubes 12 are both fixedly mounted with a shaft plate 24, and the two shaft plates 24 are both rotatably mounted with a synchronous shaft 25. The two synchronous shafts 25 and the power transmission shaft 20 are both fixedly sleeved with pulleys 3 26, and the three pulleys 3 26 are sleeved with the same synchronous belt 3 27, so that the power transmission shaft 20 drives the two synchronous shafts 25 to rotate, and the two synchronous shafts 25 and the two fan shafts 1 28 are both fixedly sleeved with bevel gears 29, and the corresponding synchronous shafts 25 and the two bevel gears 29 on the fan shaft 1 28 are meshed.

[0050] In this embodiment, the material transfer efficiency is further improved by optimizing the air intake system of the venturi tubes 12. Specifically, the inlet ends of both venturi tubes 12 are closed, and a fan shaft 28 is rotatably mounted thereon. A filter-equipped air inlet 30 is also provided. Fan blades are mounted on the fan shaft 28. When the fan shaft 28 rotates, the blades draw air through the filter-equipped air inlet 30 and discharge it toward the outlet end of the venturi tubes 12, thereby creating a negative pressure within the venturi tubes 12 and assisting in the suction and transfer of material to the crushing drum 11. Furthermore, a second shaft plate 24 is fixedly mounted on the inlet ends of both venturi tubes 12, on which a synchronization shaft 25 is rotatably mounted. The power transmission shaft 20 drives the two synchronous shafts 25 to rotate through the pulley three 26 and the synchronous belt three 27. The synchronous shaft 25 and the fan shaft one 28 are fixedly provided with a bevel gear two 29, and the corresponding bevel gear two 29 on the synchronous shaft 25 and the fan shaft one 28 are engaged with each other, so that the power transmission shaft 20 drives the fan shaft one 28 to rotate, providing power support for the venturi tube 12.

[0051] In a further preferred embodiment of the present invention, stabilizing shaft plates 31 are fixedly installed on both sides of the equipment frame 1 , and the two synchronizing shafts 25 are rotatably connected to the two stabilizing shaft plates 31 respectively.

[0052] In this embodiment, the mounting structure of the synchronization shaft 25 is further optimized by fixing stabilizing shaft plates 31 on both sides of the equipment frame 1. Specifically, the two synchronization shafts 25 are rotatably connected to the two stabilizing shaft plates 31, respectively. This mounting method ensures the stability of the synchronization shaft 25 during operation and prevents axial deviation caused by vibration or external forces.

[0053] In a further preferred embodiment of the present invention, a guide belt block 32 is fixedly mounted on the equipment rack 1 , and the guide belt block 32 contacts the synchronous belt three 27 , and the contact surface of the guide belt block 32 and the synchronous belt three 27 is an arc surface.

[0054] In this embodiment, the operating stability of synchronous belt 3 27 is further optimized by fixing a guide block 32 to the equipment frame 1. The guide block 32 contacts synchronous belt 3 27, and the contact surface is an arc. This design allows synchronous belt 3 27 to fit tightly with the guide block 32 during operation, thereby effectively guiding the movement direction of synchronous belt 3 27 and preventing it from deflecting or jittering during operation. Through the guidance of the guide block 32, synchronous belt 3 27 can transmit power more smoothly, ensuring the efficiency and stability of power transmission between the power transmission shaft 20 and the synchronous shaft 25, thereby providing stable power support for the fan shaft 1 28 of the venturi tube 12.

[0055] In a further preferred embodiment of the present invention, a control box 33 is installed on the separation box 2 , and the control box 33 is connected to the drive motor 6 .

[0056] In this embodiment, a control box 33 is installed on the separation tank 2 and connected to the drive motor 6, achieving centralized control of the entire device. The operator can start or stop the drive motor 6 through the control interface or buttons on the control box 33, thereby controlling the rotation of the crushing roller 4 and the operation of the entire recycling device. This design makes operation more convenient, allowing the operator to flexibly adjust the device's operating status according to actual needs and monitor the device's operating status in real time to ensure normal operation.

[0057] In a further preferred embodiment of the present invention, the top and bottom of the crushing box 3 are both open, and the top of the crushing box 3 is expanded outward.

[0058] In this embodiment, the top and bottom of the crushing box 3 are both open, with the top flaring outward. This design allows for easier loading of waste agricultural film into the crushing box 3. The expanded top structure also accommodates more material, preventing spillage during loading. The crushed material then falls directly into the separation box 2 through the bottom opening of the crushing box 3, completing the material transfer process after initial crushing.

[0059] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments:

[0060] In another embodiment of the present invention, an air cavity is formed between the V-shaped dividing plate 18 and the inner wall of the separation box 2. The separation box 2 is located on one side of the synchronous belt 22 and is rotatably mounted with a fan shaft 24. A filter screen air inlet 24 is also provided on its side. The filter screen air inlet 24 is connected to the air cavity. The fan shaft 24 has fan blades on the part located in the air cavity so that when the fan shaft 24 rotates, the fan blades on it inhale air into the air cavity through the filter screen air inlet 24. The fan shaft 24 is fixed at one end outside the separation box 2. A synchronous wheel 35 is sleeved thereon, and the synchronous wheel 35 is connected to the synchronous belt 22 so that when the crushing roller 4 rotates, the fan shaft 2 34 is driven to rotate through the synchronous belt 22. A plurality of exhaust ports 37 are provided on both sides of the top of the V-shaped dividing plate 18. The exhaust ports 37 are arranged toward the feed end of the suction pipe 13 and are used to discharge the air in the air cavity and then blow the material into the suction pipe 13. Material guide shielding plates 38 are fixedly installed on both sides of the top of the V-shaped dividing plate 18 to separate the material while preventing the material from falling directly into the exhaust ports 37.

[0061] In this embodiment, by providing an air cavity and a second fan shaft 34 in the separation box 2, the separation and transmission process of the materials is further optimized. Specifically, an air cavity is formed between the V-shaped material separation plate 18 and the inner wall of the separation box 2. The separation box 2 is located on one side of the synchronous belt 22 and is rotatably mounted with a second fan shaft 34. A second air inlet 36 with a filter is provided on its side, and the air inlet is connected to the air cavity. Fan blades are installed on the portion of the fan shaft 34 located in the air cavity. When the fan shaft 34 rotates, the fan blades draw air into the air cavity through the second air inlet 36 with a filter. A synchronous pulley 35 is fixed on one end of the fan shaft 34 located outside the separation box 2. The synchronous pulley 35 is connected to the synchronous belt 22, so that when the crushing roller 4 rotates, the fan shaft 34 is driven to rotate through the synchronous belt 22. Multiple exhaust ports 37 are provided on both sides of the top of the V-shaped material separator 18. The exhaust ports 37 are arranged toward the feed end of the suction pipe 13 and are used to exhaust the air in the air cavity and blow the material into the suction pipe 13. In addition, material guide shielding plates 38 are fixedly installed on both sides of the top of the V-shaped material separator 18 to prevent the material from falling directly into the exhaust ports 37 while separating the material.

[0062] This embodiment significantly improves the separation and transmission efficiency of materials by providing an air cavity, a second fan shaft 34, and an exhaust port 37. First, the air in the air cavity can blow up the material after being discharged through the exhaust port 37, making it easier for the material to be sucked into the suction pipe 13, further improving the transmission efficiency of the material. Secondly, the second air inlet 36 with a filter can filter the air entering the air cavity, preventing impurities from entering the air cavity, thereby maintaining the cleanliness of the air flow and avoiding secondary contamination of the material. In addition, the design of the material guide shielding plate 38 can effectively prevent material from falling directly into the exhaust port 37, preventing material from clogging the exhaust port, ensuring the smooth discharge of the air flow, and further improving the operational stability of the equipment.

[0063] In another embodiment of the present invention, the separation net 10 can be lifted and slidably installed in the waste outlet 9, and support plates 39 are fixedly installed on both sides of the bottom of the separation box 2. A screening drive mechanism is provided on the two support plates 39 to drive the separation net 10 to shake back and forth up and down to screen the material. The screening drive mechanism includes an interleaving strip 40 fixedly installed between the two support plates 39, and a slidable sleeve is provided on the interleaving strip 40. The top of the slit frame 41 is fixedly connected to the bottom of the corresponding separation net 10, and a force-bearing synchronization plate 42 is fixedly installed on the side of the slit frame 41. A reset spring 43 is provided in the slit frame 41, and the top of the reset spring 43 is connected to the bottom of the separation net 10. The bottom of the interlaced strip 40 is fixedly connected, and the bottom end is fixedly connected to the bottom inner wall of the mouth frame 41. A camshaft 44 is rotatably installed between the two support plates 39. The camshaft 44 is located below the force-bearing synchronous plate 42. A push cam 45 is fixedly sleeved on the camshaft 44. The outer edge of the push cam 45 contacts the bottom of the force-bearing synchronous plate 42. When the push cam 45 rotates, it cooperates with the reset spring 43 to make the mouth frame 41 and the separation net 10 move up and down to separate the materials. A pulley four 46 is fixedly sleeved on the camshaft 44 and the power transmission shaft 20, and a synchronous belt four 47 is sleeved on the pulley four 46 to enable the power transmission shaft 20 to drive the camshaft 44 to rotate.

[0064] In this embodiment, the material screening process is further optimized by providing a separation net 10 that can be raised and lowered and slidably provided, as well as a screening drive mechanism. Specifically, the separation net 10 is installed in the waste outlet 9 and is shaken back and forth up and down by the screening drive mechanism. The screening drive mechanism includes a through strip plate 40 fixedly installed between two support plates 39, and a die frame 41 slidably sleeved on the through strip plate 40. The top of the die frame 41 is fixedly connected to the bottom of the separation net 10, and a force-bearing synchronization plate 42 is fixedly installed on its side. A return spring 43 is provided in the die frame 41, the top end of the return spring 43 is fixedly connected to the bottom of the through strip plate 40, and the bottom end is fixedly connected to the bottom inner wall of the die frame 41. A camshaft 44 is rotatably installed between the two support plates 39, and a push cam 45 is fixedly sleeved on the camshaft 44, and the outer edge of the push cam 45 contacts the bottom of the force-bearing synchronization plate 42. A pulley 46 is fixedly mounted on both the camshaft 44 and the power transmission shaft 20. Pulley 46 is connected via a timing belt 47, enabling the power transmission shaft 20 to drive the camshaft 44 to rotate. As the camshaft 44 rotates, the outer edge of the push cam 45 periodically pushes the force-bearing synchronization plate 42. This, in conjunction with the action of the return spring 43, causes the die frame 41 and the separation screen 10 to reciprocate up and down, thereby screening the material.

[0065] This embodiment significantly improves the screening efficiency and quality of materials by providing a separation net 10 that can be raised and lowered and a screening drive mechanism. First, the up and down reciprocating shaking of the separation net 10 can effectively prevent the material from clogging the mesh, ensuring the continuity of the screening process. Secondly, the design of the reset spring 43 can ensure that the separation net 10 can achieve stable reciprocating motion under the push of the push cam 45, further improving the screening effect. In addition, through the power transmission system of the pulley four 46 and the synchronous belt four 47, the power of the power transmission shaft 20 is transmitted to the camshaft 44, making the operation of the entire screening drive mechanism more stable and reliable. This design not only improves the screening efficiency of materials, but also reduces manual intervention and reduces the operating cost of the equipment.

[0069] In this embodiment, by providing an operating shaft 56 and a positioning insert 59 in the crushing roller 4, the fixing and unlocking mechanism of the track bar 49 is further optimized. Specifically, an assembly cavity 55 is provided in the crushing roller 4, and the operating shaft 56 is rotatably mounted in the crushing roller 4, with one end thereof extending into the assembly cavity 55 and the other end extending outside the crushing roller 4.

First, the positioning plug 59 can be accurately inserted into the positioning slot 60 on the track bar 49 to achieve a firm fixation of the track bar 49 and ensure that it will not loosen during the crushing process. Secondly, through the rotation of the operating shaft 56, the sliding of the positioning plug 59 can be flexibly controlled to achieve rapid fixing or unlocking of the track bar 49, greatly improving the maintenance and replacement efficiency of the equipment.
