Description

Technical Field

[0001] The invention belongs to the technical field of buried scraper conveyors and relates to a buried scraper conveyor. Background Art

[0002] The scraper conveyor is widely used in industrial production, especially in the handling of bulk materials, to transport materials by moving the scraper in a closed machine trough. However, when the scraper conveyor is used to transport materials with high viscosity or high humidity, such as solid waste, the solid waste is easy to adhere to and entangle the shaft, affecting the normal operation of the shaft.

[0003] A buried scraper conveyor for harmless treatment of solid waste is disclosed in the patent document with publication number CN117602283A. The present invention includes a driving shaft, a first roller, a second roller and a third roller. The present invention protects the driven shaft through a second anti-winding mechanism, and at the same time, the first roller, the second roller and the third roller form a protective cover to cover the driving shaft. During the rotation of the driving shaft, the first roller, the second roller and the third roller isolate the solid waste. However, during use, garbage is easy to adhere to the first roller, the second roller and the third roller. If it is not cleaned in time, more and more garbage will adhere. After transportation, cleaning will cause a lot of cleaning, and too much garbage will adhere to the conveying work. Moreover, if the adhered garbage is not cleaned in time and solidified and agglomerated, the later cleaning will be more inconvenient.

[0004] In order to solve the above problems, the present invention proposes an embedded scraper conveyor. Summary of the invention

[0005] In order to solve the problems existing in the background technology, the present invention proposes an embedded scraper conveyor.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A buried scraper conveyor comprises a conveying shell, one end of which is provided with a feed pipe, and the other end is provided with a discharge port, and a material-carrying partition and a conveying mechanism for transporting materials are provided in the conveying shell; the conveying mechanism comprises a first conveying belt and a first scraper, and a plurality of first scrapers are fixedly arranged at intervals on the inner side of the first conveying belt along the conveying direction; a rotating roller is rotatably arranged at one end of the conveying shell close to the discharge port, and both ends of the rotating roller are rotatably connected with a rotating ring, and a driven rotating shaft is rotatably arranged at the other end of the conveying shell, and the first conveying belt is transmission-connected between each rotating ring and the driven rotating shaft and the rotating ring; the rotating ring is connected to the rotating roller through a differential mechanism, and under the action of the differential mechanism, there is a speed difference between the rotating ring and the rotating roller, and then when the first scraper contacts the rotating roller, the first scraper slides on the outer circumference of the rotating roller, and the first scraper scrapes and cleans the rotating roller.

[0007] Furthermore, the differential mechanism comprises a driving wheel, a driven wheel and a gear ring; both ends of the rotating roller are coaxially fixedly sleeved with a driving wheel, the driving wheel is rotatably connected to the rotating ring through a bearing, the driving wheel is fixedly connected to the inner ring of the bearing, and the rotating ring is fixedly connected to the outer ring of the bearing; a driven wheel is rotatably arranged on the end surface of the rotating ring, and the driving wheel and the driven wheel are meshed; the gear ring is meshed with the driven wheel, and the gear ring is fixed to the conveying housing; a protective cover covering the gear ring is fixed to the conveying housing, and a motor is fixed to one of the protective covers, and the motor is drivingly connected to the driving wheel; The motor drives the driving wheel and the rotating roller to rotate. The driving wheel drives the driven wheel to rotate while making the driven wheel revolve around the axis of the driving wheel. The first conveyor belt moves, the first scraper moves, and the angular velocity of the driven wheel's revolution is less than the angular velocity of the rotating roller. When the first scraper contacts the rotating roller, the first scraper slides along the outer circumference of the rotating roller to clean the rotating roller.

[0008] Furthermore, the partition has a U-shaped cross section, the first scraper is matched with the partition, both ends of the first scraper are in sliding contact with both sides of the partition, and the first scraper is in sliding contact with the bottom wall of the partition.

[0009] Furthermore, a second scraper is slidably arranged on the first scraper, and the second scraper slides along the first scraper to clean the material adhered to the first scraper.

[0010] Furthermore, a first transmission roller is rotatably provided at one end of the first scraper, and a second transmission roller is rotatably provided at the other end, a first transmission belt is transmission-connected between the first transmission roller and the second transmission roller, the second scraper is fixedly connected to the first transmission belt, and the first transmission belt drives the second scraper to slide around the first scraper; the second scraper is driven to move by the first transmission belt, so that the second scraper moves around the surface of the first scraper, thereby comprehensively cleaning the first scraper, and at the same time, the second scraper moves in one direction, which can prevent the material adhering to the second scraper from sticking to the first scraper again.

[0011] Furthermore, the first transmission roller is coaxially fixedly connected with the first gear, and a rack is fixed on the inner wall of the lower side of the conveying shell, and the rack cooperates with the first gear. When the first gear is meshed with the rack, the first gear rotates, the first transmission roller rotates, and the first transmission belt drives the second scraper to move. By setting the first gear and the rack, no additional power is required to drive the first transmission belt to move, and the movement of the second scraper is combined with the movement of the first scraper, so that when the first scraper moves to a specific position, the second scraper cleans the first scraper, which is convenient for collecting the cleaned materials.

[0017] 2. When the first scraper moves around the rear rotating roller to the lower side of the first conveyor belt, the first gear will gradually mesh with the rack. Under the action of the rack, the first gear rotates, the first transmission roller rotates, the first transmission belt moves, and the second scraper slides along the first scraper to clean the materials adhered to the first scraper. After being cleaned, the first scraper bypasses the driven shaft and enters the upper side of the first conveyor belt, and then transports the materials.

[0018] 3. The second scraper moves around the surface of the first scraper in one circle to clean the first scraper comprehensively. Meanwhile, the second scraper moves in one direction to prevent the material adhered to the second scraper from adhering to the first scraper again. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 17 A buried scraper conveyor is shown.

[0023] Embodiment 1: The technical solution adopted by the present invention is as follows: an embedded scraper conveyor includes a conveying shell 2, a feed pipe 1 is installed on the upper end surface of the conveying shell 2 near the left side, and a discharge port 8 is arranged at the lower right end of the conveying shell 2. The material to be transported is put into the conveying shell 2 from the feed pipe 1, and comes out through the discharge port 8 after being transported.

[0024] A partition 6 is provided between the inner walls of the front and rear sides of the conveying housing 2, and the feed pipe 1 is located above the partition 6, and the material is put from the feed pipe 1 onto the partition 6. The cross section of the partition 6 is U-shaped, so that the material is prevented from falling from both sides of the partition 6.

[0025] A conveying mechanism is provided in the conveying shell 2 , and the conveying mechanism conveys the material put onto the partition 6 from the feed pipe 1 to the discharge port 8 .

[0026] The conveying mechanism includes a first conveyor belt 7 and a first scraper 10. The left end of the conveying shell 2 is rotatably connected to a driven rotating shaft 26, and the right end of the conveying shell 2 is rotatably connected to a rotating roller 9. Both ends of the rotating roller 9 are coaxially rotatably connected to a rotating ring 18, and each rotating ring 18 and the driven rotating shaft 26 are drivingly connected to a first conveyor belt 7. Two first conveyor belts 7 are respectively arranged on the inner walls of the conveying shell 2 on both sides. Specifically, mounting grooves are provided on the inner walls of the conveying shell 2 on both sides, and the first conveyor belt 7 is arranged in the mounting grooves. A baffle 21 is fixedly arranged in each mounting groove, and the baffle 21 is located between the upper and lower sides of the first conveyor belt 7. The partition 6 is fixedly connected to the baffle 21. In this embodiment, the baffle 21 and the conveying shell 2 are an integral structure. A differential mechanism is arranged between the rotating ring 18 and the rotating roller 9. Under the action of the differential mechanism, there is a speed difference between the angular velocity of the rotating ring 18 and the angular velocity of the rotating roller 9.

[0027] The differential mechanism includes a driving wheel 15, a driven wheel 16 and a gear ring 17. The inner wall of the conveying housing 2 is provided with a receiving groove at a position corresponding to the end of the rotating roller 9, and the end of the rotating roller 9 extends into the corresponding receiving groove. The two ends of the rotating roller 9 are coaxially fixedly connected with the driving wheel 15. The driving wheel 15 and the rotating ring 18 are rotatably connected through the bearing 19. Specifically, the driving wheel 15 is fixedly connected to the inner ring of the bearing 19, and the rotating ring 18 is fixedly connected to the outer ring of the bearing 19.

[0028] The end surface of the rotating ring 18 is rotatably connected with a driven wheel 16, and the driven wheel 16 is meshed with the driving wheel 15. Specifically, the driven wheel 16 is rotatably connected to the rotating ring 18 through a connecting shaft 20. In this embodiment, there are three driven wheels 16, and the three driven wheels 16 are evenly distributed around the axis of the driving wheel 15.

[0029] The driven wheel 16 is meshed with a toothed ring 17, and the toothed ring 17 is fixedly connected to the conveying housing 2. The driving wheel 15, the driven wheel 16 and the toothed ring 17 form a planetary gear structure. Since the toothed ring 17 is fixedly connected to the conveying housing 2, when the driving wheel 15 drives the driven wheel 16 to rotate, the speed of the driven wheel 16 is less than the speed of the driving wheel 15.

[0030] A protective cover 3 for shielding the receiving groove is fixedly connected to the conveying housing 2. A motor 5 is fixedly mounted on one of the protective covers 3, and the motor shaft of the motor 5 penetrates the protective cover 3 and is coaxially fixedly connected to the driving wheel 15.

[0031] The motor 5 is started, and the motor 5 drives the driving wheel 15 and the rotating roller 9 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate. Under the action of the gear ring 17, the driving wheel 15 rotates while revolving around the axis of the driving wheel 15. The angular velocity of the revolving driven wheel 16 is less than the angular velocity of the rotating driving wheel 15. The revolving driven wheel 16 causes the rotating ring 18 to rotate around the axis of the driving wheel 15. The rotating ring 18 drives the first conveyor belt 7 to move.

[0032] The partition 6 is located between the upper and lower sides of the first conveyor belt 7. A plurality of first scrapers 10 are fixedly connected between the two first conveyor belts 7 at intervals, and the first scraper 10 is fixedly connected to the inner side of the first conveyor belt 7. Both ends of the first scraper 10 have shoulders, and the two shoulders are respectively slidably matched with the upper ends of both sides of the partition 6. The first scraper 10 is adapted to the partition 6, and the first scraper 10 is in sliding contact with the bottom wall of the partition 6, and the two ends of the first scraper 10 are in sliding contact with the side walls of the partition 6. When the first conveyor belt 7 moves, the first conveyor belt 7 drives the first scraper 10 to move, and when the first scraper 10 is located on the upper side of the first conveyor belt 7, the first scraper 10 gradually enters the partition 6. With the movement of the first conveyor belt 7, the first scraper 10 scrapes the material on the partition 6, thereby driving the material on the partition 6 to move. The right end of the partition 6 is provided in cooperation with the rotating roller 9. When the first scraper 10 moves from the partition plate 6 to the rotating roller 9, the first scraper 10 contacts and cooperates with the rotating roller 9 and transports the material to the rotating roller 9. Then, as the rotating roller 9 rotates, the material falls from the rotating roller 9 and falls to the discharge port 8.

[0033] When the material contacts the rotating roller 9, part of the material may adhere to the rotating roller 9. If it is not cleaned in time, more and more material will adhere to the rotating roller 9, affecting the normal conveying work. Since the angular velocity of the rotating ring 18 is less than the angular velocity of the rotating roller 9, when the first scraper 10 contacts the rotating roller 9, the first scraper 10 slides on the circumferential surface of the rotating roller 9, and then scrapes off the material adhered to the rotating roller 9, so as to achieve the purpose of automatically cleaning the rotating roller 9.

[0034] Since the first scraper 10 is adapted to the partition 6 , the first scraper 10 is in sliding contact with the bottom wall and the side wall of the partition 6 , which can reduce the material adhering to the bottom wall and the side wall of the partition 6 .

[0035] Working principle: When in use, when conveying materials, the motor 5 is started, and the motor 5 drives the driving wheel 15 and the rotating roller 9 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate while making the driven wheel 16 revolve around the axis of the driving wheel 15. When the driven wheel 16 revolves, it drives the rotating ring 18 to rotate. The rotating ring 18 drives the first conveyor belt 7 to move, and the first conveyor belt 7 drives the first scraper 10 to move. When the first scraper 10 is on the upper side of the first conveyor belt 7, the first scraper 10 moves in the direction close to the rotating roller 9. When the first scraper 10 bypasses the rotating roller 9 and moves to the lower side of the first conveyor belt 7, the first scraper 10 moves away from the rotating roller 9. The material is put from the feed pipe 1 onto the partition 6. With the movement of the first conveyor belt 7, the first scraper 10 pushes the material to move in the direction close to the rotating roller 9. When the first scraper 10 moves from the partition 6 to the rotating roller 9, the first scraper 10 contacts and cooperates with the rotating roller 9 and conveys the material to the rotating roller 9. Then, as the rotating roller 9 rotates, the material falls from the rotating roller 9 and falls to the discharge port 8 .

[0036] At the same time, since the angular velocity of the rotating ring 18 is less than the angular velocity of the rotating roller 9, when the first scraper 10 contacts the rotating roller 9, the first scraper 10 slides on the circumferential surface of the rotating roller 9, and the first scraper 10 scrapes and cleans the material adhered to the rotating roller 9 to prevent the material from adhering to the rotating roller 9.

[0037] When the first scraper 10 passes around the rotating roller 9 and moves to the lower side of the first conveyor belt 7, and then passes around the driven rotating shaft 26 and moves to the upper side of the first conveyor belt 7 and contacts the partition 6, it pushes the material on the partition 6 to move toward the discharge port 8.

[0038] Accordingly, the material on the partition plate 6 is transported to the discharge port 8 by the action of the conveying mechanism.

[0039] Embodiment 2: A buried scraper conveyor includes a conveying shell 2, a feed pipe 1 is installed on the upper end surface of the conveying shell 2 near the left side, and a discharge port 8 is arranged at the lower right end of the conveying shell 2. The material to be transported is put into the conveying shell 2 from the feed pipe 1, and comes out through the discharge port 8 after being transported.

[0040] A partition 6 is provided between the inner walls of the front and rear sides of the conveying housing 2, and the feed pipe 1 is located above the partition 6, and the material is put from the feed pipe 1 onto the partition 6. The cross section of the partition 6 is U-shaped, so that the material is prevented from falling from both sides of the partition 6.

[0041] A conveying mechanism is provided in the conveying shell 2 , and the conveying mechanism conveys the material put onto the partition 6 from the feed pipe 1 to the discharge port 8 .

[0042] The conveying mechanism includes a first conveyor belt 7 and a first scraper 10. The left end of the conveying shell 2 is rotatably connected to a driven rotating shaft 26, and the right end of the conveying shell 2 is rotatably connected to a rotating roller 9. Both ends of the rotating roller 9 are coaxially rotatably connected to a rotating ring 18, and each rotating ring 18 and the driven rotating shaft 26 are drivingly connected to a first conveyor belt 7. Two first conveyor belts 7 are respectively arranged on the inner walls of the conveying shell 2 on both sides. Specifically, mounting grooves are provided on the inner walls of the conveying shell 2 on both sides, and the first conveyor belt 7 is arranged in the mounting grooves. A baffle 21 is fixedly arranged in each mounting groove, and the baffle 21 is located between the upper and lower sides of the first conveyor belt 7. The partition 6 is fixedly connected to the baffle 21. In this embodiment, the baffle 21 and the conveying shell 2 are an integral structure. A differential mechanism is arranged between the rotating ring 18 and the rotating roller 9. Under the action of the differential mechanism, there is a speed difference between the angular velocity of the rotating ring 18 and the angular velocity of the rotating roller 9.

[0043] The differential mechanism includes a driving wheel 15, a driven wheel 16 and a gear ring 17. The inner wall of the conveying housing 2 is provided with a receiving groove at a position corresponding to the end of the rotating roller 9, and the end of the rotating roller 9 extends into the corresponding receiving groove. The two ends of the rotating roller 9 are coaxially fixedly connected with the driving wheel 15. The driving wheel 15 and the rotating ring 18 are rotatably connected through the bearing 19. Specifically, the driving wheel 15 is fixedly connected to the inner ring of the bearing 19, and the rotating ring 18 is fixedly connected to the outer ring of the bearing 19.

[0044] The end surface of the rotating ring 18 is rotatably connected with a driven wheel 16, and the driven wheel 16 is meshed with the driving wheel 15. Specifically, the driven wheel 16 is rotatably connected to the rotating ring 18 through a connecting shaft 20. In this embodiment, there are three driven wheels 16, and the three driven wheels 16 are evenly distributed around the axis of the driving wheel 15.

[0045] The driven wheel 16 is meshed with a toothed ring 17, and the toothed ring 17 is fixedly connected to the conveying housing 2. The driving wheel 15, the driven wheel 16 and the toothed ring 17 form a planetary gear structure. Since the toothed ring 17 is fixedly connected to the conveying housing 2, when the driving wheel 15 drives the driven wheel 16 to rotate, the speed of the driven wheel 16 is less than the speed of the driving wheel 15.

[0046] A protective cover 3 for shielding the receiving groove is fixedly connected to the conveying housing 2. A motor 5 is fixedly mounted on one of the protective covers 3, and the motor shaft of the motor 5 penetrates the protective cover 3 and is coaxially fixedly connected to the driving wheel 15.

[0047] The motor 5 is started, and the motor 5 drives the driving wheel 15 and the rotating roller 9 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate. Under the action of the gear ring 17, the driving wheel 15 rotates while revolving around the axis of the driving wheel 15. The angular velocity of the revolving driven wheel 16 is less than the angular velocity of the rotating driving wheel 15. The revolving driven wheel 16 causes the rotating ring 18 to rotate around the axis of the driving wheel 15. The rotating ring 18 drives the first conveyor belt 7 to move.

[0048] The partition 6 is located between the upper and lower sides of the first conveyor belt 7. A plurality of first scrapers 10 are fixedly connected between the two first conveyor belts 7 at intervals, and the first scraper 10 is fixedly connected to the inner side of the first conveyor belt 7. Both ends of the first scraper 10 have shoulders, and the two shoulders are respectively slidably matched with the upper ends of both sides of the partition 6. The first scraper 10 is adapted to the partition 6, and the first scraper 10 is in sliding contact with the bottom wall of the partition 6, and the two ends of the first scraper 10 are in sliding contact with the side walls of the partition 6. When the first conveyor belt 7 moves, the first conveyor belt 7 drives the first scraper 10 to move, and when the first scraper 10 is located on the upper side of the first conveyor belt 7, the first scraper 10 gradually enters the partition 6. With the movement of the first conveyor belt 7, the first scraper 10 scrapes the material on the partition 6, thereby driving the material on the partition 6 to move. The right end of the partition 6 is provided in cooperation with the rotating roller 9. When the first scraper 10 moves from the partition plate 6 to the rotating roller 9, the first scraper 10 contacts and cooperates with the rotating roller 9 and transports the material to the rotating roller 9. Then, as the rotating roller 9 rotates, the material falls from the rotating roller 9 and falls to the discharge port 8.

[0049] When the material contacts the rotating roller 9, part of the material may adhere to the rotating roller 9. If it is not cleaned in time, more and more material will adhere to the rotating roller 9, affecting the normal conveying work. Since the angular velocity of the rotating ring 18 is less than the angular velocity of the rotating roller 9, when the first scraper 10 contacts the rotating roller 9, the first scraper 10 slides on the circumferential surface of the rotating roller 9, and then scrapes off the material adhered to the rotating roller 9, so as to achieve the purpose of automatically cleaning the rotating roller 9.

[0050] Since the first scraper 10 is adapted to the partition 6 , the first scraper 10 is in sliding contact with the bottom wall and the side wall of the partition 6 , which can reduce the material adhering to the bottom wall and the side wall of the partition 6 .

[0051] When the first scraper 10 pushes the material to move, the material will adhere to the first scraper 10. In order to clean the first scraper 10 in time, the second scraper 23 is slidably arranged on the first scraper 10, and when the second scraper 23 slides along the first scraper 10, the first scraper 10 is cleaned.

[0052] The first transmission belt 11 is wound around the first scraper 10. Specifically, a first transmission roller 24 is rotatably mounted on one end of the first scraper 10, and a second transmission roller 25 is rotatably mounted on the other end. The first transmission belt 11 is transmission-connected between the first transmission roller 24 and the second transmission roller 25, and the first scraper 10 is located inside the first transmission belt 11. The first transmission belt 11 is fixedly connected to the second scraper 23. When the first transmission belt 11 moves, the second scraper 23 is driven to move, and then the second scraper 23 slides around the first scraper 10 to clean the first scraper 10 comprehensively.

[0053] The first transmission roller 24 is coaxially fixedly connected with the first gear 22, and a rack 12 is fixedly arranged on the inner wall of the conveying housing 2, and the rack 12 cooperates with the first gear 22. When the first scraper 10 gradually moves to the lower side of the first conveyor belt 7 after bypassing the rotating roller 9 to the right, the rack 12 gradually meshes with the first gear 22. After the rack 12 meshes with the first gear 22, as the first scraper 10 moves, under the action of the rack 12, the first gear 22 rotates, and then the first transmission roller 24 rotates, the first transmission belt 11 moves, and the first transmission belt 11 drives the second scraper 23 to move. The first transmission belt 11 slides along the surface of the first scraper 10 to clean the first scraper 10. Through the arrangement of the first gear 22 and the rack 12, no additional power is required to drive the first transmission belt 11 to move, and the movement of the second scraper 23 is combined with the movement of the first scraper 10, so that when the first scraper 10 moves to a specific position, the second scraper 23 cleans the first scraper 10, which is convenient for collecting the cleaned materials.

[0054] A collecting port is provided at the lower side of the conveying housing 2 corresponding to the rack 12, and a collecting bucket 4 is provided below the collecting port. The materials cleaned by the first scraper 10 by the second scraper 23 fall from the collecting port into the collecting bucket 4, so that the materials can be collected conveniently.

[0055] The collecting bucket 4 is detachably connected to the conveying shell 2. Specifically, the parts on both sides of the collecting port of the conveying shell 2 are provided with card slots, and flanges are fixedly provided on both sides of the collecting bucket 4, and the flanges are slidably set in the card slots on the same side. Furthermore, the parts on both sides of the collecting port of the conveying shell 2 are fixed with connecting plates 13, and the connecting plates 13 and the collecting bucket 4 are connected by fastening screws 14. A handle is provided on the collecting bucket 4. When the collecting bucket 4 needs to be cleaned, the fastening screws 14 are removed, and then the collecting bucket 4 is pulled out to clean the collecting bucket 4. Afterwards, the collecting bucket 4 is connected to the conveying shell 2 by the cooperation of the flange and the card slot, and then the collecting bucket 4 is fixedly connected to the connecting plate 13 by the fastening screws 14.

[0056] Working principle: When in use, when conveying materials, the motor 5 is started, and the motor 5 drives the driving wheel 15 and the rotating roller 9 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate while making the driven wheel 16 revolve around the axis of the driving wheel 15. When the driven wheel 16 revolves, it drives the rotating ring 18 to rotate. The rotating ring 18 drives the first conveyor belt 7 to move, and the first conveyor belt 7 drives the first scraper 10 to move. When the first scraper 10 is on the upper side of the first conveyor belt 7, the first scraper 10 moves in the direction close to the rotating roller 9. When the first scraper 10 bypasses the rotating roller 9 and moves to the lower side of the first conveyor belt 7, the first scraper 10 moves away from the rotating roller 9. The material is put from the feed pipe 1 onto the partition 6, and the first scraper 10 pushes the material to move in the direction close to the rotating roller 9. When the material contacts the rotating roller 9, as the rotating roller 9 rotates, the material falls from the rotating roller 9 and falls into the discharge port 8.

[0057] At the same time, since the angular velocity of the rotating ring 18 is less than the angular velocity of the rotating roller 9, when the first scraper 10 contacts the rotating roller 9, the first scraper 10 slides on the circumferential surface of the rotating roller 9, and the first scraper 10 scrapes and cleans the material adhered to the rotating roller 9 to prevent the material from adhering to the rotating roller 9.

[0058] When the first scraper 10 moves to the lower side of the first conveyor belt 7 after passing the rotating roller 9, it then passes the driven rotating shaft 26 and moves to the upper side of the first conveyor belt 7 and contacts the partition 6, pushing the material on the partition 6 to move toward the discharge port 8. Accordingly, the material on the partition 6 is transported to the discharge port 8 under the action of the conveying mechanism.

[0059] During the process of conveying materials, the first scraper 10 will also be adhered to the materials. When the first scraper 10 bypasses the rotating roller 9 and moves to the lower side of the first conveyor belt 7, when the first gear 22 is meshed with the rack 12, as the first scraper 10 moves, under the action of the rack 12, the first gear 22 rotates, the first transmission roller 24 rotates, the first transmission belt 11 moves, and the first transmission belt 11 drives the second scraper 23 to slide along the first scraper 10. The second scraper 23 cleans the first scraper 10, and the cleaned materials enter the collecting bucket 4 through the collecting port. When the collecting bucket 4 needs to be cleaned, the fastening screw 14 is removed, and then the collecting bucket 4 is pulled out to pour out the materials in the collecting bucket 4. After that, the collecting bucket 4 is clamped to the conveying shell 2 through the cooperation of the flange and the card slot, and the collecting bucket 4 is fixedly connected to the connecting plate 13 by the fastening screw 14.

[0060] Embodiment 3: This embodiment is an improvement based on embodiment 2.

[0061] The upper ends of both sides of the partition 6 are fixedly connected with second blocks 28, which block the gap between the end of the first transmission belt 11 and the baffle 21 to prevent materials from entering the gap between the end of the first transmission belt 11 and the baffle 21.

[0062] A first stopper 27 is fixedly sleeved on the outer circumference of the rotating roller 9 , and the first stopper 27 blocks the gap between the end of the first transmission belt 11 and the rotating ring 18 to prevent materials from entering the gap between the end of the first transmission belt 11 and the rotating ring 18 .

[0063] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
