Description

Technical Field

[0001] This utility model belongs to the technical field of scraper conveyors, specifically relating to a scraper mechanism and a scraper conveyor. Background Technology

[0002] A scraper conveyor is a continuous mechanical device suitable for conveying bulk materials. It is widely used in industries such as mining, grain and oil processing, and building materials to realize material transportation. The scraper conveyor is driven by a motor to rotate the sprocket, which drives the scraper chain and scrapers to circulate inside the conveyor. The material moves along the inside of the scraper conveyor under the action of scraper pressure and chain traction.

[0003] When scraper conveyors are in use, materials or dust easily adhere to the scraper plates. If not cleaned in time, this will affect operating efficiency and equipment lifespan. Therefore, it is necessary for workers to clean the plates. However, current technology usually involves manual cleaning, which is not only time-consuming and labor-intensive, but also increases the risk of injury to workers from the scraper mechanism and scraper chain inside the scraper conveyor. To address this problem, designing a scraper mechanism and scraper conveyor is a problem that we need to solve. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a scraper conveyor scraper mechanism and a scraper conveyor.

[0005] To achieve the above objectives, this utility model provides a scraper mechanism for a scraper conveyor, including a connecting member, in which a plate is inserted, and a limiting member is inserted into the connecting member and the plate; and a dust scraping assembly, which is used to clean and disassemble the plate, and is connected to the connecting member, the plate, and the limiting member.

[0006] In the above technical solution, the dust scraper assembly further includes a slot formed on the outer wall of the limiting member, a card block is inserted into the inside of the slot, and a connecting rod is fixedly connected to the outer wall of the card block.

[0007] In the above technical solution, the connecting rod is further sleeved on the outer wall of the end of the limiting member, the connecting rod is rotatably connected to the outer wall of the connecting member, and a sealing sheet is fixedly connected to the outer wall of the connecting rod.

[0008] In the above technical solution, a first circular slider is fixedly connected to the outer wall of the end of the connecting rod away from the limiting member, and a scraper is slidably connected to the outer wall of the first circular slider.

[0009] In the above technical solution, the scraper is further fitted onto the outer wall of the plate, the sealing sheet is attached to one side of the scraper, and the two ends of the scraper are fixedly connected to a second circular slider.

[0010] In the above technical solution, the outer wall of the second circular slider is slidably connected to a guide groove, and the outer wall of the guide groove is connected to a slot.

[0011] A scraper conveyor with a scraper mechanism includes a conveyor body. A belt drive component and a motor are fixedly connected to the outer wall of the conveyor body. Two rotating shafts are rotatably connected inside the conveyor body. Sprockets are fixedly connected to the outer walls of both rotating shafts. One of the rotating shafts is fixedly connected to the large pulley of the belt drive component. The output shaft of the motor is fixedly connected to the small pulley of the belt drive component. Scraper chains mesh with the outer walls of the two sprockets. Multiple connecting members are provided and fixedly connected to the outer walls of the scraper chains at equal intervals. The plate body fits against the inner wall of the conveyor body. Guide grooves and slots are formed on the inner wall of the conveyor body.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By setting up a dust scraping component, the scraper can scrape off the material and dust adhering to the plate body as the plate body is driven to rotate through the connecting parts, so as to achieve the effect of automatically cleaning the outer wall of the plate body. This eliminates the need for manual cleaning of the plate body, reduces the workload of the staff, and avoids the impact of material or dust adhering to the plate body on operating efficiency or damage to the scraper conveyor. By setting up a dust scraper assembly, when workers need to replace a panel, they can move the panel to be replaced to the slotted position, then pull the scraper on the panel upwards along the slot, eventually stopping the locking block in place of the limiting component. This allows workers to pull out the limiting component and replace the old panel with a new one. Finally, the limiting component is reinserted and the scraper is pushed back to its original position, ultimately locking the limiting component again with the locking block and slot. This achieves the effect of quickly replacing the panel, making it convenient for workers to install or remove panels. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 3 The scraper mechanism of the scraper conveyor shown includes a connector 5, a plate 6 is inserted into the inside of each connector 5, and a limiting member 7 is inserted into the inside of the connector 5 and the plate 6; a dust scraping assembly is used to clean and disassemble the plate 6, and the dust scraping assembly is connected to the connector 5, the plate 6, and the limiting member 7.

[0017] like Figures 2 to 5 As shown, the dust scraper assembly includes a slot 8 formed on the outer wall of the limiting member 7. A locking block 9 is inserted into the slot 8. A connecting rod 10 is fixedly connected to the outer wall of the locking block 9. The connecting rod 10 is sleeved on the outer wall of the end of the limiting member 7. The connecting rod 10 is rotatably connected to the outer wall of the connecting member 5. A sealing plate 11 is fixedly connected to the outer wall of the connecting rod 10. A first circular slider 12 is fixedly connected to the outer wall of the end of the connecting rod 10 away from the limiting member 7. A scraper 13 is slidably connected to the outer wall of the first circular slider 12. The circular shape of the first circular slider 12 allows it to slide along the groove of the scraper 13. When rotating, the scraper 13 is sleeved on the outer wall of the plate 6, and the sealing plate 11 is attached to one side of the scraper 13. By setting the sealing plate 11, the sliding groove on the scraper 13 can be blocked and sealed when the scraper 13 does not clean the material or dust adhering to the outer wall of the plate 6, so as to prevent the material or dust from entering the interior of the sliding groove of the scraper 13 and affecting the sliding of the first circular slider 12 along the sliding groove of the scraper 13. The two ends of the scraper 13 are fixedly connected to the second circular slider 14, and the outer wall of the second circular slider 14 is slidably connected to the guide groove 15. The outer wall of the guide groove 15 is connected to the slot 16.

[0018] like Figure 1The scraper conveyor shown includes a scraper mechanism, comprising a conveyor body 1. A belt drive component (a prior art component consisting of a housing, two pulleys of different sizes, and a belt) and a motor are fixedly connected to the outer wall of the conveyor body 1. Two rotating shafts 2 are rotatably connected inside the conveyor body 1. A sprocket 3 is fixedly connected to the outer wall of each of the two rotating shafts 2. One of the rotating shafts 2 is fixedly connected to the large pulley of the belt drive component. The output shaft of the motor is fixedly connected to the small pulley of the belt drive component. Scraper chains 4 are meshed on the outer walls of the two sprockets 3. Multiple connecting parts 5 are fixedly connected to the outer wall of the scraper chains 4 at equal intervals. A plate 6 is attached to the inner wall of the conveyor body 1. Guide grooves 15 and slots 16 are formed on the inner wall of the conveyor body 1.

[0019] Working principle: When the operator powers on and starts the scraper conveyor, the motor drives the rotating shaft 2 via the belt drive component. The rotating shaft 2 drives the scraper chain 4 to rotate via the sprocket 3. The scraper chain 4 drives the plate body 6 to circulate and convey the material inside the conveyor body 1 via the connecting piece 5. The second circular sliders 14 at both ends of the scraper 13 sleeved on the plate body 6 will slide inside the guide groove 15. As the plate body 6 pushes the material out of the conveyor body 1 and continues to be driven to rotate by the scraper chain 4 through the connecting piece 5, the second circular sliders 14 will slide to the part where the guide groove 15 and the rotation trajectory of the scraper chain 4 are misaligned. At this time, the plate body 6 and the scraper 13 sliding along the inside of the guide groove 15 via the second circular sliders 14 are misaligned. This allows the plate body 6 to drive the scraper 13 to move while the scraper 13 moves. 13 slides along the outer wall of the plate 6, allowing the scraper 13 to scrape off the material or dust adhering to the plate 6. When the second circular slider 14 slides to the part where the guide groove 15 coincides with the rotation trajectory of the scraper chain 4, the scraper 13, which slides along the inside of the guide groove 15 via the second circular slider 14, will slide back to its original position along the outer wall of the plate 6, waiting for the next cleaning of the outer wall of the plate 6. As the scraper chain 4 continuously drives the plate 6 to rotate through the connecting piece 5, the scraper 13 will continuously scrape off the material or dust adhering to the outer wall of the plate 6, thereby achieving the effect of automatically cleaning the outer wall of the plate 6. This eliminates the need for manual cleaning of the plate 6 by the staff, reducing the workload of the staff and preventing the plate 6 from being affected by material or dust, thus avoiding damage to the scraper conveyor. Furthermore, when the worker needs to replace plate 6, the plate 6 to be replaced can be moved to the position of slot 16, and then the scraper 13 on this plate 6 can be pulled, so that the scraper 13 drives the second circular slider 14 from the inside of the guide groove 15 to the inside of the slot 16 and rises along the slot 16. The rise of the scraper 13 will pull the connecting rod 10 to rotate through the first circular slider 12 until the two connecting rods 10 connected to the outer wall of the connector 5 are parallel and stop. At this time, the locking block 9 inside the connecting rod 10 will slide along the inside of the locking groove 8 to the opening of the locking groove 8, so that the locking block 9 stops fixing the limiting member 7 through the locking groove 8, allowing the worker to remove the limiting member 7 from the connecting rod 10 and the connecting rod 10. After pulling out the internal parts of component 5 and plate 6, the staff can remove the old plate 6 and replace it with a new plate 6 in this position. Finally, the limiting component 7 is re-aligned and inserted into the internal parts of connector 5, plate 6 and connecting rod 10. The connecting rod 10 is rotated so that the connecting rod 10 drives the locking block 9 to rotate away from the opening of the slot 8. The limiting component 7 is locked and limited again by the locking block 9 and the slot 8. The rotation of the connecting rod 10 will drive the first circular slider 12 to slide along the sliding groove inside the scraper 13 and drive the scraper 13 to descend and re-enter the internal part of the guide groove 15. At this time, the disassembly and assembly of plate 6 is completed, so as to achieve the effect of quickly replacing plate 6 and making it convenient for staff to install or remove plate 6.
