Description

Technical Field

[0001] This invention relates to the field of transportation machinery technology, and more specifically, to a scraper structure for a suspended scraper conveyor. Background Technology

[0002] In the field of grain processing and storage, scraper conveyors are one of the most critical and fundamental logistics equipment. They are widely used in almost all stages of grain processing, from receiving, cleaning, and storing raw grains such as wheat, corn, rice, and soybeans, to processing, packaging, and distributing finished grains such as flour and rice, as well as feed processing and port grain loading and unloading. From inter-warehouse transfers in large grain depots and unloading bulk grains from ships at docks, to the diversion and redirection of materials between different processes within processing plants, scraper conveyors bear the heavy responsibility of ensuring the continuous and efficient flow of bulk grains. As a continuous conveying device that transports bulk materials within a closed rectangular shell using a moving scraper chain, the working principle of a scraper conveyor is to fix scrapers onto a chain to form a scraper chain, which is driven by a drive unit at the head of the conveyor to drive the sprocket, causing the scraper chain to circulate.

[0003] During operation, when material accumulates at the feed inlet, the scraper experiences a sharp increase in operating resistance as it cuts into the material layer. This causes the scraper root and drive chain connection to be subjected to alternating stress far exceeding design standards, making the scraper prone to bending and deformation. This severely shortens the equipment's service life and increases the risk of downtime. Summary of the Invention

[0004] The present invention provides a scraper structure for a suspended scraper conveyor, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this solution provides a scraper structure for a suspended scraper conveyor, including a conveying channel. A drive motor is installed at one end of the conveying channel, and a drive chain is assembled inside the conveying channel. The drive motor drives the drive chain. Multiple mounting blocks are fixedly installed on the drive chain. A rotating plate is rotatably connected inside each mounting block. A sliding block is slidably connected to one side of the rotating plate. A sliding groove is formed on the rotating plate, and a sliding column is slidably arranged inside the sliding groove. The end of the sliding column is fixedly connected to one side of the sliding block. A scraper is rotatably installed on the outside of the sliding block, and a protrusion is provided at one corner of the scraper.

[0006] Optionally, a guide slope is fixedly provided on the rotating plate, and the protrusion is slidably connected to the guide slope. The guide slope is used to guide the position of the protrusion.

[0007] Optionally, the inner wall of the mounting block is provided with a guide arc groove, the sliding column passes through the sliding groove, and one end of the sliding column is slidably connected to the guide arc groove.

[0008] Optionally, a limiting slider is slidably mounted inside the mounting block, a guide plate is rotatably connected to the limiting slider, one end of the guide plate has a sharp bevel, and a limiting block is fixedly mounted on the limiting slider, the limiting block being used to limit the position of the guide plate.

[0009] Optionally, a positioning spring is fixedly connected to one side of the limiting slider, and the other end of the positioning spring is fixedly connected to the interior of the mounting block.

[0010] Optionally, a rotating gear is fixedly connected to the pivot of the guide plate and the limiting slider, and the rotating gear meshes with a guide rack.

[0011] Optionally, the guide rack is provided with a limiting groove, and a limiting tooth is slidably connected inside the limiting groove. A first spring is fixedly connected to one side of the limiting tooth, and the first spring is located inside the limiting groove.

[0012] Optionally, a sealing groove is provided on one side of the mounting block, and a sealing slider is slidably connected inside the sealing groove. The sealing slider is slidably connected to the mounting block, and one side of the sealing slider is used to abut against the sharp bevel.

[0013] Optionally, a second spring is fixedly connected to one side of the sealing slider, and the other end of the second spring is fixedly connected to the interior of the mounting block; When the sharp bevel contacts the sealing slider, the sealing slider slides into the mounting block, and at the same time the second spring deforms.

[0014] Through the above technical solution, the scraper structure for the suspended scraper conveyor provided in this solution, when in use: 1. During normal conveying, the scraper maintains a relatively vertical posture. When the grain accumulates at the feed inlet, causing a sharp increase in resistance, the scraper is forced to tilt and drive the rotating plate to rotate. The sliding column slides along the guide arc groove to lift the scraper as a whole. At the same time, the protrusion and the guide slope work together to drive the scraper to make further fine adjustments. By reducing the material receiving area and lifting gap, the scraper is effectively prevented from bending due to overload, and the breakage rate of grain caused by compression is greatly reduced.

[0015] 2. To further improve the stability of the scraper, if the resistance continues to increase, the rotating plate will push the limiting slider to the left, compress the positioning spring and extend the guide plate with a sharp bevel. The sharp bevel first longitudinally divides the accumulated material. When the resistance reaches the limit, the guide plate tilts further under the meshing action of the rotating gear and the guide rack, forming a slope surface to guide the grain to slide over the mounting block. At the same time, the scraper rotates to the maximum posture and leaves the maximum gap at the bottom. 3. To further improve the stability of the scraper, once the resistance decreases, the compressed positioning spring immediately pushes the limiting slider to the right, causing the rotating plate to rotate. The scraper descends and restores its vertical pushing angle, and the guide plate is pulled back into the mounting block. At the same time, the sealing slider automatically closes the sealing groove under the action of the second spring to prevent grain from entering the internal parts of the mounting block and wearing out during normal conveying. The guide plate also returns to horizontal under the action of the rack and pinion and is locked by the limiting teeth. The entire reset process requires no manual intervention and responds quickly, which not only ensures the rapid recovery of conveying efficiency but also greatly extends the service life of the equipment and reduces the frequency of maintenance.

[0016] Other features and advantages of this solution will be described in detail in the following detailed implementation section. Attached Figure Description

The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0021] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0022] According to some embodiments of this solution, a scraper structure for a suspended scraper conveyor is provided, for reference. Figures 1-10 As shown, the scraper structure of the suspended scraper conveyor includes a conveying channel 1, a drive motor 2 installed at one end of the conveying channel 1, a drive chain 3 assembled inside the conveying channel 1, the drive motor 2 driving the drive chain 3, and multiple mounting blocks 4 fixedly mounted on the drive chain 3. A rotating plate 5 is rotatably connected inside the mounting block 4, and a sliding block 6 is slidably connected to one side of the rotating plate 5. See details... Figure 4 and Figure 5The rotating plate 5 has a sliding groove 7, and a sliding column 8 is slidably arranged inside the sliding groove 7. The end of the sliding column 8 is fixedly connected to the sliding block 6. A scraper 9 is rotatably installed on the outside of the sliding block 6. The scraper 9 is a plate with a long rectangular cross section, and a protrusion 10 is provided at one corner of the scraper 9.

[0023] It should be noted that one side of the protrusion 10 will abut against the inner side of the rotating plate 5. When the mounting block 4 drives the scraper 9 to slide to the left, the left side of the scraper 9 abuts against the inside of the rotating plate 5 through the protrusion 10, and at the same time, the rotating plate 5 abuts against the right side of the scraper 9, so that when the scraper 9 pushes the grain, the scraper 9 can be in a relatively perpendicular state to the inside of the conveying channel 1. Meanwhile, the conveying channel 1, the drive motor 2 and the drive chain 3 are all existing technologies, and professionals in this field can freely select them according to the actual situation.

[0024] When grain needs to be transported, the drive motor 2 drives the drive chain 3 to rotate in the conveying channel 1. While the drive chain 3 is rotating, it drives the mounting block 4 and the scraper 9 to move together in the conveying channel 1, so that the scraper 9 can transport the grain in the conveying channel 1.

[0025] When grain accumulates at the feed inlet of conveyor channel 1, the mounting block 4 drives the scraper 9 to push the accumulated grain, which greatly increases the running resistance of the scraper 9, thus pushing the scraper 9 to tilt. While the scraper 9 is rotating, the protrusion 10 drives the rotating plate 5 to tilt together. By tilting the scraper 9, the amount of material pushed by the scraper 9 can be reduced, thereby reducing the load on the scraper 9. At the same time, it can also reduce the squeezing of the grain stuck between the scraper 9 and the conveyor channel 1, which can prevent the grain from breaking due to squeezing during the grain conveying process.

[0026] A guide slope 11 is fixedly provided on the rotating plate 5. The protrusion 10 is slidably connected to the guide slope 11. The guide slope 11 is used to guide the position of the protrusion 10. Through the design of the protrusion 10 abutting against the guide slope 11, the protrusion 10 can drive the scraper 9 to tilt when it abuts against the guide slope 11.

[0027] The inner wall of the mounting block 4 is provided with a guide arc groove 12, and the sliding post 8 passes through the sliding groove 7, with one end of the sliding post 8 slidably connected to the guide arc groove 12; it should be noted that the guide arc groove 12 is designed to be inclined inward, so that when the sliding post 8 slides in the guide arc groove 12, see Figure 7 Under the guidance of the guide arc groove 12 on the sliding column 8, the sliding column 8 and the sliding block 6 can be pulled closer to the rotating shaft of the rotating plate 5, while the scraper 9 can slide into the rotating plate 5.

[0028] It should be noted that, see Figure 5The inner side of the rotating plate 5 is provided with a sliding block 6, a sliding groove 7, a scraper 9, a protrusion 10, a guide slope 11, and a guide arc groove 12. In normal state, the scraper 9 is vertical and relatively perpendicular to the conveying channel 1. At this time, the protrusion 10 abuts against the straight surface below the guide slope 11. When the load on the scraper 9 is too large, the scraper 9 drives the rotating plate 5 to tilt. At the same time, the sliding column 8, guided by the guide arc groove 12, pulls the sliding block 6 and the scraper 9 to slide into the rotating plate 5. When the load on the scraper 9 increases further, the scraper 9 will drive the rotating plate 5 to rotate further. Under the guidance of the guide arc groove 12, the sliding block 6 pulls the scraper 9 to continue sliding into the rotating plate 5. Under the guidance of the guide slope 11, the protrusion 10 drives the scraper 9 to rotate to a state relatively perpendicular to the conveying channel 1. At the same time, the distance between the scraper 9 and the conveying channel 1 is at its maximum. As the rotating plate 5 tilts, it causes the sliding block 6 and the sliding column 8 to rotate together, allowing the sliding column 8 to slide within the guide groove 12. Guided by the guide groove 12, [the following is observed]. Figure 5 This allows the sliding column 8 to pull the sliding block 6 and the protrusion 10 upward together, so that while the scraper 9 is rotating, the distance between the scraper 9 and the conveying channel 1 can be increased, reducing the amount pushed by the scraper 9, thereby further reducing the load on the scraper 9 and preventing the scraper 9 from bending due to excessive load. It should be noted that during the process of guiding the sliding block 6 and scraper 9 to slide upward, the guide groove 12 will drive the protrusion 10 to slide upward together. At this time, the protrusion 10 will abut against and slide against the inner side of the rotating plate 5.

[0029] A limiting slider 13 is slidably mounted inside the mounting block 4. A guide plate 14 is rotatably connected to the limiting slider 13. One end of the guide plate 14 has a sharp bevel 15. A limiting block 16 is fixedly mounted on the limiting slider 13. The limiting block 16 is used to limit the position of the guide plate 14. Through the design of the sharp bevel 15, the piled grain can be divided, thereby reducing the resistance when the mounting block 4 and the scraper 9 are pushed.

[0030] A positioning spring 17 is fixedly connected to one side of the limiting slider 13, and the other end of the positioning spring 17 is fixedly connected to the inside of the mounting block 4. The positioning spring 17 is designed to limit the position of the limiting slider 13 and provide power for its reset. Furthermore, the design of the positioning spring 17 and the limiting slider 13... (See...) Figure 5When the scraper 9 pushes the material, the resistance of the material will exert a force that tilts to the left on the scraper 9 and the rotating plate 5. The positioning spring 17 pushes the limiting slider 13 to the right to make one side of the limiting slider 13 contact one side of the rotating plate 5, thereby limiting the position of the rotating plate 5 and preventing the rotating plate 5 and the scraper 9 from tilting to the left. Only when the resistance of the subsequent material is greater than the elastic force of the positioning spring 17 will the rotating plate 5 and the scraper 9 be tilted.

[0031] A rotating gear 18 is fixedly connected to the pivot of the guide plate 14 and the limiting slider 13, and the rotating gear 18 is meshed with a guide rack 19.

[0032] The guide rack 19 is provided with a limiting groove 20. The limiting groove 20 is designed to limit the sliding position of the limiting tooth 21 and prevent the limiting tooth 21 from shifting position during the sliding process. The limiting tooth 21 is slidably connected inside the limiting groove 20. A first spring 22 is fixedly connected to one side of the limiting tooth 21. The first spring 22 is located inside the limiting groove 20.

[0033] It should be noted that when the rotating gear 18 slides, it will drive the limiting tooth 21 to slide together. The design of the limiting tooth 21 can limit the position of the rotating gear 18 and prevent the position of the rotating gear 18 and the guide plate 14 from being offset. At the same time, the pulling of the first spring 22 ensures that the rotating gear 18 and the guide plate 14 always have a pulling force. In addition, the limiting block 16 can prevent the guide plate 14 from rotating excessively.

[0034] A sealing groove 23 is provided on one side of the mounting block 4. A sealing slider 24 is slidably connected inside the sealing groove 23. The sealing slider 24 is slidably connected to the mounting block 4. One side of the sealing slider 24 is used to abut against the sharp inclined surface 15 to reduce the accumulation of grain entering the interior of the mounting block 4.

[0035] A second spring 25 is fixedly connected to one side of the sealing slider 24, and the other end of the second spring 25 is fixedly connected to the inside of the mounting block 4. The design of the second spring 25 is described below. Figure 8 It can apply an upward sliding force to the sealing slider 24, so that the sealing slider 24 can slide upward continuously, thereby sealing the sealing groove 23. When the sharp bevel 15 contacts the sealing slider 24, see Figure 8 It can apply a downward sliding force to the sealing slider 24, so that the sealing slider 24 can slide downward, while compressing the second spring 25.

[0036] As the rotating plate 5 tilts, one end of the rotating plate 5 will abut against one side of the limiting slider 13. Through this abutment against the limiting slider 13, [the following is observed]. Figure 5 This allows the limiting slider 13 to slide to the left. While the limiting slider 13 slides to the left, it can resist the positioning spring 17, causing the positioning spring 17 to deform. While the limiting slider 13 slides to the left, it can also drive the guide plate 14 and the sharp inclined surface 15 to slide to the left together.

[0037] As the sharp bevel 15 slides to the left, it abuts against the sealing slider 24, allowing the sealing slider 24 to slide downwards and open the sealing groove 23. It should be noted that, under the action of the second spring 25, one end of the sealing slider 24 will be tightly attached to the lower side of the guide plate 14, which can reduce the amount of grain entering the interior of the mounting block 4 through the sealing groove 23 when the guide plate 14 slides to the left. The design of the guide plate 14 sliding out of the mounting block 4 allows the sharp bevel 15 to divide the accumulated grain, reducing the resistance of the mounting block 4 and the scraper 9 when sliding to the left.

[0038] If there is a large amount of accumulated grain, causing a sharp increase in the pressure of the scraper 9, the scraper 9 will rotate at a greater angle under the action of the grain, thereby causing the limiting slider 13 to slide further to the left. At the same time, it will drive the guide plate 14 to slide to the left as well. Meanwhile, the rotating gear 18 and the guide rack 19 mesh, allowing the guide plate 14 to tilt. Through the tilting of the guide plate 14, the mounting block 4 and the scraper 9 can divide and guide the accumulated grain when sliding to the left, allowing the grain to slide over the mounting block 4, thereby further reducing the resistance of the scraper 9 sliding.

[0039] As the rotating plate 5 continues to rotate, the sliding column 8 can pull the sliding block 6 and the scraper 9 further upward under the action of the guide arc groove 12, so that the protrusion 10 can abut against the inclined surface of the guide slope 11. Under the guidance of the guide slope 11, the scraper 9 can rotate on the sliding block 6, so that the scraper 9 can be in a relatively perpendicular state to the inside of the conveying channel 1. At the same time, there is a certain gap between the scraper 9 and the bottom surface of the conveying channel 1. Through this design, the load on the scraper 9 can be reduced.

[0040] When the resistance at the front end of scraper 9 decreases, the compressed positioning spring 17 immediately pushes the limiting slider 13 to slide to the right. When the limiting slider 13 moves to the right, it will abut against one side of the rotating plate 5, pushing the rotating plate 5 to rotate in the opposite direction, causing the sliding column 8 to slide along the original path of the guide arc groove 12. At the same time, the sliding column 8 slides down in the sliding groove 7. At this time, the sliding block 6 and scraper 9 descend as a whole, restoring the normal working distance with the bottom surface of the conveying channel 1. At the same time, the protrusion 10 disengages from the inclined surface of the guide slope 11, and the scraper 9 rotates back to the normal pushing angle under the cooperation of the rotating shaft. As the limiting slider 13 moves to the right, the guide plate 14 and the sharp slope 15 fixed thereto will be pulled back into the mounting block 4. At the same time, the sealing slider 24, which was originally pushed open by the sharp slope, automatically slides upward under the elastic force of the second spring 25, closing the sealing groove 23 and preventing the grain from entering the interior of the mounting block 4 during normal conveying. While the guide plate 14 slides back, it returns from the inclined posture to the horizontal state under the action of the guide rack 19, and is then fixed under the restriction of the limiting tooth 21.

[0041] Through the above technical solution, the scraper structure of the suspended scraper conveyor provided by this solution maintains a relatively vertical posture during normal conveying, with the sealing slider 24 enclosing the mounting block 4 to ensure efficient quantitative pushing. When grain accumulates at the feed inlet, causing a sharp increase in resistance, the scraper 9 is forced to tilt and drive the rotating plate 5 to rotate. The sliding column 8 slides along the guide arc groove 12, causing the scraper 9 to lift as a whole. By reducing the material receiving area and lifting gap, the scraper 9 is prevented from overloading and bending, and the grain breakage rate is reduced. If the resistance continues to increase, the rotating plate 5 pushes the limiting slider 13 to the left, compressing the positioning spring 17 and extending the guide plate 14 with a sharp inclined surface 15, which divides the material. When the ultimate resistance is reached, the guide plate 14... The rotating gear 18 tilts under the meshing action of the guide rack 19, guiding the grain to slide over the mounting block 4, greatly reducing the pushing resistance. The scraper 9 rotates further to its maximum position. At the same time, the protrusion 10 and the guide slope 11 cooperate to drive the scraper 9 to adjust further, so that the scraper 9 is vertical again but leaves the maximum gap at the bottom. When the subsequent resistance decreases, the positioning spring 17 immediately pushes the limiting slider 13 to the right, causing the rotating plate 5 to rotate. The scraper 9 descends and restores the vertical pushing angle. The guide plate 14 is pulled back into the mounting block 4. The sealing slider 24 automatically closes the sealing groove 23 under the action of the second spring 25. At the same time, the guide plate 14 returns to horizontal under the action of the guide rack 19 and is locked by the limiting tooth 21, realizing a quick reset without intervention.

[0042] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0044] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
