Technical Field

[0001] The present invention relates to the technical field of plastic bottle processing, and specifically to an automatic storage bin for plastic bottle flakes. Background Art

[0002] The processing of plastic bottle flakes by an automatic storage bin usually includes storage and transportation. The automatic storage bin can store plastic bottle flakes in large quantities, reduce manual intervention, and improve storage efficiency. It is usually equipped with a conveyor belt to transport plastic bottle flakes from the storage bin to different parts of the production line. Such a system is widely used in industries such as plastic bottle production, recycling, and reprocessing, which can greatly improve production efficiency and reduce labor costs.

[0003] The patent with the publication number CN115893027A discloses an automatic feeding storage bin for plastic bottle flakes, including: a storage bin and a conveyor. A feeding port is opened at the upper end of the storage bin. A side groove is provided on one side of the feeding port. A sleeve shaft is rotatably installed in the side groove. An arc plate for blocking the feeding port is fixedly installed on the outer side of the sleeve shaft. An installation hole is opened in the middle of the upper end of the storage bin. A moving rod is arranged in the installation hole. The sleeve shaft is sleeved outside the moving rod and meshed therewith. A square groove is opened in the middle of the upper end of the moving rod, and a fixed disk is fixedly sleeved outside. A spring is arranged between the fixed disk and the storage bin. One end of the conveyor is provided with a T-shaped support column. When the present invention needs to store plastic bottle flakes, under the self-gravity of the conveyor, through the cooperation of the T-shaped support column, the moving rod, the sleeve shaft, the arc plate rotation, and the side groove, the feeding port is automatically exposed for automatic feeding and storage of plastic bottle flakes. It has a high degree of automation, improves efficiency, saves manpower, and has high safety. However, this patent has the problems that the occupied area of the conveying support structure for feeding is large and the flexibility is low. Therefore, it is very necessary to design an automatic storage bin for plastic bottle flakes. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic storage bin for plastic bottle flakes to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: An automatic storage bin for plastic bottle flakes, including a storage tank. A support frame is fixedly connected to the bottom surface of the storage tank. A feeding frame is arranged on the side surface of the storage tank. A feeding port is fixedly connected to the bottom end of the storage tank. An inlet port is opened on the top surface of the storage tank. An automatic feeding mechanism is arranged on the feeding frame. A compression mechanism is arranged at the top end inside the storage tank. An auxiliary discharging mechanism is arranged below the compression mechanism.

[0006] According to the above technical solution, the automatic feeding mechanism includes a support framework, the support framework is fixedly connected to the top surface of the feeding rack, fixed shaft seats are fixedly connected to the bottom surfaces of the upper and lower ends of the support framework, a driving sprocket is rotatably connected above the fixed shaft seat at the bottom, a transmission chain is meshed and connected to the outside of the driving sprocket, corner sprockets are arranged in the middle of both sides of the transmission chain, a plurality of equally spaced fence fixing frames are fixedly connected to the inner side of the support framework, a baffle fence is fixedly connected to the top end of the fence fixing frame, a partition baffle is fixedly connected to the middle of the inner side of the baffle fence, a worm groove chain is arranged outside the partition baffle, a convex block connecting shaft is rotatably connected to the top surface of the fixed shaft seat at the top, a transmission sprocket is fixedly connected to the top end of the convex block connecting shaft, a connecting link is fixedly connected to the side of the transmission chain away from the support framework, a plurality of pushing partition plates are fixedly connected to the outer surface of the worm groove chain, and a tilting plate is fixedly connected to the inner side of the top end of the baffle fence.

[0007] According to the above technical solution, connecting seat bars are fixedly connected to both sides of the top end of the support framework, and a fixed seat bar is fixedly connected to the top surface of the storage tank.

[0008] According to the above technical solution, the corner sprocket is rotatably connected to the support framework, the worm groove chain penetrates from the inner top surface of the baffle fence to the bottom surface, the connecting seat bar is slidably connected to the fixed seat bar, one end of the fixed seat bar close to the support framework is integrally triangular, the end of the connecting link away from the transmission chain is fixedly connected to the worm groove chain. When the driving sprocket on the fixed shaft seat rotates to drive the transmission chain to rotate, the transmission chain is supported and lifted by the corner sprocket, the transmission chain rotates to drive the connected transmission sprocket to rotate. During the movement of the transmission chain, the connecting link connected to the transmission chain drives the worm groove chain to move. After putting the crushed materials into the inner bottom side of the baffle fence, the pushing partition plates in the baffle fence move upward along the baffle fence driven by the worm groove chain. When the pushing partition plates push the materials to the tilting plate, since there is no baffle fence blocking at the tilting plate, the crushed materials between the two pushing partition plates enter the inside of the feeding port along the tilting plate to achieve automatic feeding. Through the overall structure of the support framework fitting the outer wall of the storage tank, the occupied area is reduced compared with the traditional transmission mechanism. The feeding port at the top of the storage tank is not convenient to move either. Through the cooperation of the transmission chain and the corner sprocket, the chain structure is combined with the support framework to improve the transmission efficiency of the crushed materials. At the same time, wheels are installed on the feeding rack, and the wheels can be used to assist the movement of the feeding rack and the support framework. Through the movement, the support framework is disengaged from the fixed seat bar through the connected connecting seat bar, so that the support framework moves to be docked with the storage tank in the empty bin state. Through the docking of the fixed seat bar and the connecting seat bar on the storage tank, the top of the baffle fence is docked with the feeding port, thereby improving the flexibility of the support framework and the feeding rack, and quickly positioning through the docking of the fixed seat bar and the connecting seat bar, and improving the loading efficiency of the storage tank.

[0009] According to the above technical solution, the compression mechanism includes a tilting guide plate, which is arranged inside the storage tank. The center of the top end of the storage tank is rotatably connected with a linkage shaft. A guide end is fixedly connected to the outer side of the linkage shaft. A concave material guide plate is fixedly connected to the bottom surface of the guide end. Support brackets are fixedly connected to both sides of the concave material guide plate.

[0010] According to the above technical solution, a tilting guide plate is fixedly connected to the top surface of each support bracket. Pressing slopes are arranged on both sides of the concave material guide plate. A blanking notch is formed on the side surface of each pressing slope. An upper turning plate and a lower turning plate are respectively hinged inside the blanking notch.

[0011] According to the above technical solution, the side cross-sectional shape of the guide end is triangular. The overall shape of the tilting guide plate is fan-shaped, and the thickness of the top arc edge of the tilting guide plate gradually decreases towards the center of the straight edge. The top end of the linkage shaft fits with the bottom end of the convex block connecting shaft. When the transmission sprocket rotates, the transmission sprocket drives the connected convex block connecting shaft to rotate. At this time, the connecting seat bar connected to the support frame and the fixed seat bar are in a butt joint state, so that the convex block connecting shaft and the top end of the linkage shaft are also in a butt joint state. The rotation of the convex block connecting shaft drives the connected linkage shaft to rotate, causing the linkage shaft to drive the concave material guide plate and the guide end to rotate. The materials falling into the feeding port will be guided by the tilting guide plate and enter the inside of the concave material guide plate. As the materials in the concave material guide plate increase, the materials in the concave material guide plate are guided by the guide end and enter the inside of the storage tank through the blanking notch. When the materials gradually accumulate and fit to the bottom surface of the concave material guide plate, the pressing slope of the concave material guide plate squeezes the crushed materials downward, causing the fragments to be squeezed against each other to reduce the gap between them. After the pressing slope squeezes the crushed materials, the gap between the blanking notch and the squeezed crushed materials is reduced, so that the materials in the concave material guide plate continue to fill the inside of the storage tank. During the rotation of the concave material guide plate, the upper turning plate and the lower turning plate block the blanking notch, causing the lower turning plate to press the crushed materials below the blanking notch under the action of gravity, preventing the crushed materials from expanding and blocking the blanking notch. At the same time, the upper turning plate droops under the action of gravity, preventing the pressed crushed materials from bursting and falling back into the concave material guide plate. By pressing the crushed materials inside the storage tank by the concave material guide plate, the efficiency of squeezing the crushed materials is improved, the gap and volume between the crushed materials are reduced, and the capacity of the storage tank is increased.

[0012] According to the above technical solution, the auxiliary discharging mechanism includes an auxiliary shaft cylinder, which is fixedly connected to the outer bottom end of the linkage shaft. Four vertical rod seats are fixedly connected to the outer sides of the upper and lower ends of the auxiliary shaft cylinder. A limiting block is fixedly connected to the outer side of each vertical rod seat. A turning shaft rod is fixedly connected to the inside of each vertical rod seat. A material loosening arc plate is rotatably connected to the outer side of the turning shaft rod. A reverse resistance piece is fixedly connected to the end of the material loosening arc plate away from the turning shaft rod. Stop rods are fixedly connected to the upper and lower ends of the material loosening arc plate. A plurality of guide pieces are fixedly connected to the side of the material loosening arc plate close to the auxiliary shaft cylinder. A guide piece groove is formed on the outer side surface of the auxiliary shaft cylinder.

[0013] According to the above technical solution, the guide slot corresponds to the position of the guide sheet, and the loose material arc plate is in mutual contact with the outer side of the auxiliary shaft cylinder. When the linkage shaft rotates counterclockwise, the crushed materials around the inside of the storage tank pass through contacting the loose material arc plate, causing the loose material arc plate to rotate around the turning shaft rod and fit the side of the auxiliary shaft cylinder, and making the guide sheet on the side of the loose material arc plate fit with the guide slot. By rotating the linkage shaft counterclockwise, the loose material arc plate is in the storage state. When the compressed materials in the storage tank need to be discharged through the discharging port, at this time, when the linkage shaft rotates clockwise, the loose material arc plate outside the auxiliary shaft cylinder contacts the compressed crushed materials through the reverse resistance piece, increasing the resistance of the reverse resistance piece. The resistance of the reverse resistance piece drives the loose material arc plate to deflect around the turning shaft rod. After the loose material arc plate deflects, it contacts the limit block on the side of the vertical rod seat through the stop rod, causing the limit block to push the stop rod to make the loose material arc plate rotate around the axis of the auxiliary shaft cylinder. In addition, when the loose material arc plate rotates, it guides the contacted crushed materials downward through the guide sheet, enabling the crushed materials to be conveyed from below the discharging port. As the loose material arc plate continues to rotate, the gaps between the compressed fragments are enlarged, thereby reducing the frictional force between the crushed materials and improving the output efficiency of the compressed crushed materials inside the storage tank.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0015] In the present invention, by providing a support skeleton, a fixed shaft seat, a driving sprocket, a transmission chain, a corner sprocket, a fence fixing frame, a connecting seat bar, a driving sprocket, a connecting chain rod, a worm groove chain, a partition baffle, a pushing partition board, a material blocking fence, a fixing seat bar, and an inclined material plate, through the cooperation of the transmission chain and the corner sprocket, the chain structure is combined with the support skeleton to improve the transmission efficiency of the crushed materials. At the same time, through the docking of the fixing seat bar on the storage tank and the connecting seat bar, the top of the material blocking fence is docked with the feeding port, thereby improving the flexibility of the support skeleton and the material conveying frame, and quickly positioning through the docking of the fixing seat bar and the connecting seat bar, improving the loading efficiency of the storage tank;

[0016] In the present invention, by providing an inclined material guiding plate, a support supporting plate, a concave material guiding plate, a discharging slot, an upper turning plate, a lower turning plate, a material guiding end, a linkage shaft, and a pressure application slope surface, by rotating the concave material guiding plate, the pressure application slope surface squeezes the crushed materials to force them downward, causing the fragments to be squeezed against each other to reduce the gaps between them. After the pressure application slope surface squeezes the crushed materials, the gap between the discharging slot and the squeezed crushed materials is reduced, so that the materials in the concave material guiding plate continue to fill the inside of the storage tank. At the same time, the upper turning plate droops due to gravity, preventing the compressed crushed materials from bursting open and falling back into the concave material guiding plate. By applying pressure to the crushed materials inside the storage tank through the concave material guiding plate, the efficiency of squeezing the crushed materials is improved, the gaps and volume between the crushed materials are reduced, and the capacity of the storage tank is increased;

[0017] In the present invention, by providing an auxiliary shaft cylinder, a vertical rod seat, a limit block, a turning shaft rod, a guide piece groove, a material loosening arc plate, a reverse resistance piece, a blocking rod, and a guide piece, when the reverse resistance piece is blocked, it drives the material loosening arc plate to deflect around the turning shaft rod. After the material loosening arc plate deflects, it contacts the limit block on the side of the vertical rod seat through the blocking rod, causing the limit block to push the blocking rod and enabling the material loosening arc plate to rotate around the axis of the auxiliary shaft cylinder. In addition, when the material loosening arc plate rotates, it guides the crushed materials in contact downward through the guide piece, enabling the crushed materials to be conveyed from below the feeding port. As the material loosening arc plate continues to rotate, the gaps between the compressed fragments are enlarged, thereby reducing the frictional force between the crushed materials and improving the output efficiency of the compressed crushed materials inside the storage tank.

[0030] The automatic feeding mechanism 5 includes a support framework 51, which is fixedly connected to the top surface of the material conveying rack 3. Fixedly connected to the bottom surfaces of both the upper and lower ends of the support framework 51 are fixed shaft seats 52. Above the fixed shaft seat 52 at the bottom, a driving sprocket 53 is rotatably connected. Meshed to the outside of the driving sprocket 53 is a transmission chain 54. At the middle parts on both sides of the transmission chain 54, corner sprockets 55 are provided. Fixedly connected to the inner side of the support framework 51 are a plurality of equally spaced fence fixing frames 56. Fixedly connected to the top ends of the fence fixing frames 56 is a material retaining fence 513. Fixedly connected to the middle of the inner side of the material retaining fence 513 is a partition baffle 511. Outside the partition baffle 511 is a worm groove chain 510. Rotatably connected to the top surface of the fixed shaft seat 52 at the top is a convex block connecting shaft 516. Fixedly connected to the top end of the convex block connecting shaft 516 is a transmission sprocket 58. Fixedly connected to the side of the transmission chain 54 away from the support framework 51 is a connecting link 59. Fixedly connected to the outer side surface of the worm groove chain 510 are a plurality of material pushing partitions 512. Fixedly connected to the inner side of the top end of the material retaining fence 513 is a tilting plate 515. Fixedly connected to both sides of the top end of the support framework 51 are connecting seat bars 57. Fixedly connected to the top surface of the storage tank 1 is a fixed seat bar 514. The corner sprockets 55 are rotatably connected to the support framework 51. The worm groove chain 510 penetrates from the inner top surface of the material retaining fence 513 to the bottom surface. The connecting seat bars 57 are slidably connected to the fixed seat bar 514. The end of the fixed seat bar 514 close to the support framework 51 is triangular as a whole. The end of the connecting link 59 away from the transmission chain 54 is fixedly connected to the worm groove chain 510. Through the cooperation of the transmission chain 54 and the corner sprockets 55, the chain structure is combined with the support framework 51 to improve the crushing material transmission efficiency. At the same time, wheels are installed on the material conveying rack 3, and the wheels can be used to assist the movement of the material conveying rack 3 and the support framework 51. Through the movement, the support framework 51 is disengaged from the fixed seat bar 514 through the connected connecting seat bars 57, so that the support framework 51 moves to dock with the storage tank 1 in the empty bin state. Through the docking of the fixed seat bar 514 on the storage tank 1 and the connecting seat bars 57, the top of the material retaining fence 513 is docked with the feeding port 8, thereby improving the flexibility of the support framework 51 and the material conveying rack 3, and quickly positioning through the docking of the fixed seat bar 514 and the connecting seat bars 57, improving the loading efficiency of the storage tank 1.

[0031] The compression mechanism 6 includes a tilting guide plate 61 which is arranged inside the storage tank 1. A linkage shaft 68 is rotatably connected to the center of the top end of the storage tank 1. A material guiding end 67 is fixedly connected to the outer side surface of the linkage shaft 68. A concave material guiding plate 63 is fixedly connected to the bottom surface of the material guiding end 67. Support brackets 62 are fixedly connected to both sides of the concave material guiding plate 63. A tilting guide plate 61 is fixedly connected to the top surface of each support bracket 62. Pressing slopes 69 are arranged on both sides of the concave material guiding plate 63. A material discharging notch 64 is formed in the side surface of each pressing slope 69. An upper turning plate 65 and a lower turning plate 66 are respectively hinged inside the material discharging notch 64. The side cross-sectional shape of the material guiding end 67 is triangular. The overall shape of the tilting guide plate 61 is fan-shaped, and the thickness of the top arc edge of the tilting guide plate 61 gradually decreases towards the center of the straight edge. The top end of the linkage shaft 68 fits with the bottom end of the convex block connecting shaft 516. By rotating the concave material guiding plate 63, the pressing slope 69 squeezes the crushed material downward, causing the fragments to be squeezed against each other to reduce the gap between them. After the pressing slope 69 squeezes the crushed material, the gap between the material discharging notch 64 and the squeezed crushed material decreases, so that the material in the concave material guiding plate 63 continues to fill the inside of the storage tank 1. During the rotation of the concave material guiding plate 63, the upper turning plate 65 and the lower turning plate 66 block the material discharging notch 64, so that the lower turning plate 66 presses the crushed material below the material discharging notch 64 under the action of gravity, preventing the crushed material from expanding and blocking the material discharging notch 64. At the same time, the upper turning plate 65 droops under the action of gravity, preventing the pressed crushed material from bursting and falling back into the concave material guiding plate 63. By pressing the crushed material inside the storage tank 1 with the concave material guiding plate 63, the efficiency of squeezing the crushed material is improved, the gap and volume between the crushed materials are reduced, and the capacity of the storage tank 1 is increased.

[0032] The auxiliary discharging mechanism 7 includes an auxiliary shaft cylinder 71, which is fixedly connected to the outer bottom end of the linkage shaft 68. Four vertical rod seats 72 are fixedly connected to the outer sides of the upper and lower ends of the auxiliary shaft cylinder 71. A limiting block 73 is fixedly connected to the outer side surface of each vertical rod seat 72. A turning shaft rod 74 is fixedly connected to the inner side of each vertical rod seat 72. A material loosening arc plate 76 is rotatably connected to the outer side of the turning shaft rod 74. One end of the material loosening arc plate 76 far from the turning shaft rod 74 is fixedly connected with a reverse resistance piece 77. Stop rods 78 are fixedly connected to the upper and lower ends of the material loosening arc plate 76. A plurality of guide pieces 79 are fixedly connected to the side of the material loosening arc plate 76 close to the auxiliary shaft cylinder 71. A guide piece groove 75 is formed on the outer side surface of the auxiliary shaft cylinder 71, and the guide piece groove 75 corresponds to the position of the guide pieces 79. The material loosening arc plate 76 is in mutual contact with the outer side surface of the auxiliary shaft cylinder 71. The reverse resistance piece 77 is blocked to drive the material loosening arc plate 76 to deflect around the turning shaft rod 74. After the material loosening arc plate 76 deflects, it contacts the limiting block 73 on the side surface of the vertical rod seat 72 through the stop rod 78, so that the limiting block 73 pushes the stop rod 78 to make the material loosening arc plate 76 rotate around the axis of the auxiliary shaft cylinder 71. In addition, when the material loosening arc plate 76 rotates, the crushed materials in contact are guided downward through the guide pieces 79, so that the crushed materials are conveyed from below the feeding port 4. As the material loosening arc plate 76 continues to rotate, the gaps between the compressed fragments are enlarged, so that the frictional force between the crushed materials is reduced, and the output efficiency of the compressed crushed materials inside the storage tank 1 is improved.

[0033] Working principle: When the driving sprocket 53 on the fixed shaft seat 52 rotates to drive the transmission chain 54 to rotate, the transmission chain 54 is supported and lifted by the corner sprocket 55, and the transmission chain 54 rotates to drive the connected transmission sprocket 58 to rotate. During the movement of the transmission chain 54, the connecting link 59 connected to the transmission chain 54 drives the worm groove chain 510 to move. After the crushed material is placed inside the bottom side of the baffle fence 513, the pushing partition plate 512 in the baffle fence 513 moves upward along the baffle fence 513 driven by the worm groove chain 510. When the pushing partition plate 512 pushes the material to the tilting plate 515, since there is no baffle fence 513 blocking at the tilting plate 515, the crushed material between the two pushing partition plates 512 enters the inside of the feeding port 8 along the tilting plate 515 to achieve automatic feeding. The overall structure of the support frame 51 fits the outer wall of the storage tank 1, thus reducing the occupied area compared with the traditional transmission mechanism. The feeding port 8 located at the top of the storage tank 1 is also not convenient to move. Through the cooperation of the transmission chain 54 and the corner sprocket 55, the chain structure and the support frame 51 are used to improve the transmission efficiency of the crushed material. At the same time, wheels are installed on the material conveying frame 3, and the wheels can be used to assist the movement of the material conveying frame 3 and the support frame 51. Through the movement, the support frame 51 is separated from the fixed seat bar 514 through the connected seat bar 57, so that the support frame 51 moves to be docked with the storage tank 1 in the empty tank state. Through the docking of the fixed seat bar 514 and the seat bar 57 on the storage tank 1, the top of the baffle fence 513 is docked with the feeding port 8, thereby improving the flexibility of the support frame 51 and the material conveying frame 3, and quickly positioning through the docking of the fixed seat bar 514 and the seat bar 57 to improve the loading efficiency of the storage tank 1;

[0034] When the driving sprocket 58 rotates, the driving sprocket 58 drives the connected convex block coupling shaft 516 to rotate. At this time, the connecting seat bar 57 connected to the support frame 51 and the fixed seat bar 514 are in a butting state, so that the convex block coupling shaft 516 and the top end of the linkage shaft 68 are also in a butting state. The rotation of the convex block coupling shaft 516 drives the connected linkage shaft 68 to rotate, causing the linkage shaft 68 to drive the concave material guide plate 63 and the material guiding end 67 to rotate. The material falling from the feeding port 8 will be guided by the inclined material guide plate 61 and enter the inner side of the concave material guide plate 63. As the material in the concave material guide plate 63 increases, the material in the concave material guide plate 63 is guided by the material guiding end 67 and enters the inside of the storage tank 1 from the blanking chute 64. When the material gradually accumulates and adheres to the bottom surface of the concave material guide plate 63, the pressure application slope surface 69 squeezes the crushed material downward by the rotation of the concave material guide plate 63, causing the fragments to be squeezed against each other under force and reducing the gap between them. After the pressure application slope surface 69 squeezes the crushed material, the gap between the blanking chute 64 and the squeezed crushed material increases, so that the material in the concave material guide plate 63 continues to fill the inside of the storage tank 1. During the rotation of the concave material guide plate 63, the blanking chute 64 is blocked by the upper turning plate 65 and the lower turning plate 66, so that the lower turning plate 66 presses the crushed material below the blanking chute 64 under the action of gravity, preventing the crushed material from expanding and blocking the blanking chute 64. At the same time, the upper turning plate 65 droops under the action of gravity, preventing the crushed material under pressure from bursting and falling back into the concave material guide plate 63. By pressing the crushed material inside the storage tank 1 by the concave material guide plate 63, the efficiency of squeezing the crushed material is improved, the gap and volume between the crushed materials are reduced, and the capacity of the storage tank 1 is increased;

[0035] When the linkage shaft 68 rotates counterclockwise, the crushed material around the inside of the storage tank 1 passes through the contact loosening arc plate 76, causing the loosening arc plate 76 to rotate around the turning shaft rod 74 and fit the side surface of the auxiliary shaft cylinder 71, and making the guide piece 79 on the side surface of the loosening arc plate 76 fit the guide piece groove 75. By rotating the linkage shaft 68 counterclockwise, the loosening arc plate 76 is in a retracted state. When the compressed material in the storage tank 1 needs to be discharged through the discharging port 4, at this time, when the linkage shaft 68 rotates clockwise, the loosening arc plate 76 outside the auxiliary shaft cylinder 71 contacts the compressed crushed material through the reverse resistance piece 77, causing the resistance of the reverse resistance piece 77 to increase. The resistance of the reverse resistance piece 77 drives the loosening arc plate 76 to deflect around the turning shaft rod 74. After the loosening arc plate 76 deflects, it contacts the limiting block 73 on the side surface of the vertical rod seat 72 through the stop rod 78, causing the limiting block 73 to push the stop rod 78 to make the loosening arc plate 76 rotate around the axis of the auxiliary shaft cylinder 71. In addition, the rotation of the loosening arc plate 76 guides the contacted crushed material downward through the guide piece 79, so that the crushed material is conveyed from below the discharging port 4. As the loosening arc plate 76 continues to rotate, the gap between the compressed fragments is enlarged, so that the frictional force between the crushed materials in contact is reduced, and the output efficiency of the compressed crushed material inside the storage tank 1 is improved.
