Description

Technical Field

[0001] This utility model relates to the field of coal transportation technology, and more specifically, to a scraper cleaning device. Background Technology

[0002] During coal mining, the moisture content of coal varies across different regions due to variations in natural environment and geological conditions. Therefore, coal can be categorized into wet coal and dry coal based on its moisture content. Wet coal, with its higher moisture content, exhibits greater caking and adhesion properties. While this facilitates shaping in some processing steps, it also creates difficulties for transportation during mining and processing.

[0003] During the transportation of wet coal, after contact with the surface of the transport equipment, the wet coal will physically or chemically adhere to the surface. This is especially true for wet coal with high moisture content, which will form an adsorbed water film on the equipment surface, further enhancing the adhesion. Due to the adhesion of wet coal to the transport equipment surface and its tendency to stick together, coal accumulates on the surface of the transport equipment, becoming increasingly difficult to clean. This increases the weight of the transport equipment, leading to increased energy consumption, and also reduces the amount of coal transported each time, resulting in decreased transport efficiency. Utility Model Content

[0004] This invention provides a scraper cleaning device to solve the problem in the prior art that coal accumulates thickly on the surface of transport equipment and is difficult to clean.

[0005] To address the aforementioned problems, this utility model provides a scraper cleaning device, comprising a frame, a pushing assembly, and a driving assembly. The frame has a hopper, an inlet, and an outlet. The inlet is located at the top of the hopper, and the outlet is located at the bottom and end of the hopper. The pushing assembly includes a pushing plate and a cleaning plate, both movably disposed within the hopper and spaced apart from each other. The pushing plate is spaced from the bottom of the hopper and pushes the material within the hopper to the outlet. The end of the cleaning plate abuts against the bottom of the hopper. The driving mechanism is mounted on the frame and is connected to both the pushing plate and the cleaning plate, driving them to move synchronously.

[0006] Furthermore, the drive mechanism includes a chain and multiple sprockets, which are spaced apart along the extension direction of the hopper. The chain is mounted on the multiple sprockets, and the pusher plate and cleaning plate are fixed on the chain. The sprockets cooperate with the chain to drive the pusher plate and cleaning plate to move.

[0007] Furthermore, the cleaning plate includes a plate body, a cleaning component, and a first elastic member. A driving mechanism is drivenly connected to the plate body. The plate body has a first end and a second end positioned relative to the hopper. The end face of the second end has a mounting groove extending along the width direction of the hopper. The cleaning component is movably disposed within the mounting groove. The first elastic member is disposed within the mounting groove and abuts against both the cleaning component and the plate body. The first elastic member drives the cleaning component to move away from the first end, and the cleaning component abuts against the bottom of the hopper.

[0008] Furthermore, there is a limiting structure between the mounting slot and the cleaning component, which is used to limit the movement of the cleaning component relative to the plate.

[0009] Furthermore, the mounting groove has relatively arranged sidewalls along the moving direction of the plate, and a limiting protrusion is provided on the sidewall. The cleaning component has a relatively arranged cleaning end and a connecting end along the depth direction of the mounting groove. The cleaning end is located away from the first end, and the connecting end is connected to the first elastic component. The cleaning end extends outside the mounting groove. The cleaning end and the connecting end are located on both sides of the limiting protrusion along the depth direction. The cleaning end and the connecting end cooperate with the limiting protrusion to form a limiting structure.

[0010] Furthermore, limit protrusions are provided on both side walls, with the limit protrusions located near the second end. The dimensions of the cleaning end and the connecting end along the moving direction are larger than the dimensions of the middle part of the cleaning component. The two sides of the cleaning end are respectively limited and engaged with the two limit protrusions, and the two sides of the connecting end are respectively limited and engaged with the two limit protrusions.

[0011] Furthermore, the scraper cleaning device also includes a first vibrating element, which is oscillatingly mounted on the frame along the extension direction of the hopper. The first vibrating element has a first vibrating end located on the outside of the hopper and is used to strike the side wall of the hopper.

[0012] Furthermore, the cleaning plate is provided with a driving protrusion located on the side wall of the cleaning plate along the width direction of the hopper. The first vibrating element also has a driving end. The bottom surface of the hopper has a clearance groove, which is located near the side wall of the hopper and extends along the extension direction of the hopper. The first vibrating element passes through the clearance groove, and the driving end is located inside the hopper. The driving protrusion cooperates with the driving end to drive the first vibrating element to swing.

[0013] Furthermore, the scraper cleaning device also includes a support shaft and a second elastic element. The support shaft is located outside the hopper and at the bottom of the hopper. The middle part of the first vibrating element is located on the support shaft. The second elastic element is located between the support shaft and the first vibrating element. The first vibrating element has a power storage state and a striking state that are arranged opposite to each other. When the driving protrusion abuts against the driving end and drives the driving end to move, the first vibrating element is in the power storage state. When the driving protrusion separates from the driving end, the first vibrating element swings in the opposite direction to switch to the striking state, and the first vibrating end strikes the bottom of the hopper.

[0014] Furthermore, the scraper cleaning device also includes a discharge cylinder and a second vibrating element, which are detachably mounted on the frame and located at the discharge port; the second vibrating element is oscillatingly mounted on the frame along the extension direction of the hopper, and the second vibrating element has a second vibrating end located on the outside of the hopper, and the second vibrating end is used to strike the side wall of the discharge cylinder.

[0015] This invention utilizes a pushing component and a driving component within a hopper. When material enters the scraper cleaning device from the inlet, it falls into the hopper. Simultaneously, the driving component drives the pushing component to transport the material to the outlet, thus completing the material transport process. However, during this transport, due to the adhesiveness of the material, some material may adhere to the bottom of the hopper. To prevent this adhesion, the pushing component includes a pushing plate and a cleaning plate. The end of the cleaning plate abuts against the bottom of the hopper. As the cleaning plate moves from the top to the bottom, its end contacts the bottom, causing it to continuously scrape and rub against the material adhering to the hopper bottom while pushing the material towards the outlet. This effectively removes the material from the bottom surface and allows it to smoothly enter the outlet. This prevents material adhesion and accumulation at the bottom of the hopper, ensuring normal material transport. Attached Figure Description

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0048] like Figure 1 and Figure 5 As shown, this utility model embodiment provides a scraper cleaning device, including a frame 10, a pushing assembly 20, and a driving assembly. The frame 10 has a hopper 11, a feed inlet 12, and a discharge outlet 13. The feed inlet 12 is located at the top of the hopper 11, and the discharge outlet 13 is located at the bottom of the hopper 11, with the discharge outlet 13 positioned at one end of the hopper 11. The pushing assembly 20 includes a pushing plate 21 and a cleaning plate 22, both movably disposed within the hopper 11 and spaced apart from each other. The pushing plate 21 is spaced from the bottom of the hopper 11. The pushing plate 21 pushes the material within the hopper 11 to drive it to the discharge outlet 13, and the end of the cleaning plate 22 abuts against the bottom of the hopper 11. The drive mechanism is mounted on the frame 10 and is connected to the pusher plate 21 and the cleaning plate 22 respectively. The drive mechanism is used to drive the pusher plate 21 and the cleaning plate 22 to move synchronously.

[0049] In the embodiments of this application, the frame 10 includes a hopper 11, a feed inlet 12, and a discharge outlet 13. The feed inlet 12 is located at the top of the hopper 11, and the discharge outlet 13 is located at the bottom of the hopper 11. Therefore, materials can directly enter the hopper 11 smoothly by gravity. Simultaneously, the location of the discharge outlet 13 at the end of the hopper 11 allows for a certain travel distance in material transport, facilitating adjustment of the amount of material fed per unit time and preventing excessive or insufficient feeding. When material enters the feed inlet 12, it falls onto the bottom of the hopper 11. Simultaneously, the drive assembly drives the push plate and cleaning plate 22 to move synchronously towards the discharge outlet 13, causing the material located between the push plate and cleaning plate 22 to move towards and be transported to the discharge outlet 13 under their influence. During the above process, since the end of the cleaning plate 22 abuts against the bottom of the hopper 11, the cleaning plate 22 can scrape off the material attached to the bottom of the hopper 11 as it moves toward the discharge port 13, preventing the material from accumulating at the bottom of the hopper 11 and ensuring the efficiency of material transportation and the smoothness of material conveying.

[0050] like Figure 1 and Figure 5 As shown, the drive mechanism includes a chain 31 and multiple sprockets 30. The multiple sprockets 30 are distributed at intervals along the extension direction of the hopper 11. The chain 31 is mounted on the multiple sprockets 30. The pusher plate 21 and the cleaning plate 22 are fixed on the chain 31. The sprockets 30 cooperate with the chain 31 to drive the pusher plate 21 and the cleaning plate 22 to move. Figure 1 The X-axis represents the extension direction of the hopper 11, and the Y-axis represents the width direction of the hopper 11.

[0051] In this embodiment, by setting sprockets 30 at both ends of the hopper 11 and circumferentially arranging a chain 31 around the sprockets 30, the chain 31 is divided into an upper chain layer and a lower chain layer. The upper chain layer 31 is located at the top of the hopper 11, and the lower chain layer 31 is located above the bottom of the hopper 11. The rotation of the sprockets 30 along their own axes is transformed into the reciprocating movement of the chain 31 between the sprockets 30, thereby causing the pusher plate 21 and the cleaning plate 22 fixed on the chain 31 to reciprocate between the upper and lower chain layers. Furthermore, the chain links have equal intervals, providing convenient conditions for the equal-interval arrangement of the cleaning plate 22 and the pusher plate 21, allowing materials to fall directly into the gap between the cleaning plate 22 and the pusher plate 21, facilitating material transport. Simultaneously, the chain 31 and sprockets 30 can adapt to scenarios with high dust and particle content in coal mines, ensuring the normal and effective operation of the scraper cleaning device. In some embodiments of this application, the drive mechanism includes two sprockets 30, which are located at both ends of the bottom of the hopper 11, thereby ensuring that the material can be effectively transported to the discharge port 13.

[0052] In other embodiments of this application, the drive mechanism includes three sprockets 30, which are equally spaced. Two sprockets 30 are located at both ends of the hopper 11, and one sprocket 30 is located in the middle of the hopper 11. By adding a sprocket 30 in the middle of the hopper 11, the pusher plate 21 and the cleaning plate 22 can move more smoothly, avoiding swaying of the pusher plate 21 and the cleaning plate 22 under the drive of the chain 31, which would otherwise reduce the material conveying efficiency.

[0053] like Figure 1 , Figure 3 and Figure 4As shown, the cleaning plate 22 includes a plate body 221, a cleaning component 223, and a first elastic member 224. A driving mechanism is driven to the plate body 221. The plate body 221 has a first end and a second end positioned relative to the hopper 11. The end face of the second end has a mounting groove 222 extending along the width direction of the hopper 11. The cleaning component 223 is movably disposed within the mounting groove 222. The first elastic member 224 is disposed within the mounting groove 222 and abuts against both the cleaning component 223 and the plate body 221. The first elastic member 224 drives the cleaning component 223 to move away from the first end, and the cleaning component 223 abuts against the bottom of the hopper 11. Figure 4 The Z-axis is the depth direction of the mounting groove 222.

[0054] In the embodiments of this application, the plate body 221 of the cleaning plate 22 is fixedly connected to the drive mechanism, and the mounting groove 222 within the plate body 221 provides a space for accommodating the cleaning component 223 and the first elastic component 224. Simultaneously, the two ends of the first elastic component 224 abut against the cleaning component 223 and the plate body 221 respectively, allowing the cleaning component 223 to move up and down with damping along the depth direction of the mounting groove 222 within the mounting groove 222. With the above configuration, as the cleaning plate 22 gradually moves from the top of the hopper 11 to the bottom of the hopper 11, the cleaning component 223 begins to abut against the bottom of the hopper 11. This causes the cleaning component 223 to move away from the bottom of the hopper 11 and compress the first elastic component 224, giving the first elastic component 224 elastic potential energy. The first elastic component 224 then applies an elastic force to the cleaning component 223, causing the cleaning component 223 to maintain a strong and stable contact with the bottom of the hopper 11, thereby ensuring that the cleaning plate 22 can effectively scrape off the material adhering to the bottom of the hopper 11.

[0055] In other embodiments of this application, the cleaning plate 22 further includes a plurality of first elastic elements 224, which are equally spaced in the mounting groove 222, so that the cleaning element 223 can move more smoothly in the mounting groove 222, and the first elastic elements 224 apply a stronger and more balanced elastic force to ensure stable contact between the cleaning element 223 and the bottom of the hopper 11.

[0056] like Figure 4As shown, a limiting structure exists between the mounting groove 222 and the cleaning component 223, which limits the movement of the cleaning component 223 relative to the plate 221. The mounting groove 222 has opposing sidewalls along the moving direction of the plate 221, and a limiting protrusion 225 is provided on the sidewall. The cleaning component 223 has a cleaning end 226 and a connecting end 227 opposing each other along the depth direction of the mounting groove 222. The cleaning end 226 is located away from the first end, and the connecting end 227 is connected to the first elastic member 224. The cleaning end 226 extends outside the mounting groove 222. The cleaning end 226 and the connecting end 227 are located on both sides of the limiting protrusion 225 along the depth direction of the mounting groove 222, and the cleaning end 226 and the connecting end 227 cooperate with the limiting protrusion 225 to form a limiting structure.

[0057] In this embodiment, by providing a limiting protrusion 225 on the side wall of the mounting groove 222, the connecting end 227 cannot disengage from the mounting groove 222 when the cleaning component 223 moves within the mounting groove 222, thereby ensuring stable contact between the connecting end 227 and the first elastic member 224. This also prevents the cleaning end 226 of the cleaning component 223 from entering the mounting groove 222, avoiding the possibility of the cleaning component 223 getting stuck in the mounting groove 222. Furthermore, the limiting structure formed by the cleaning end 226 and the connecting end 227 respectively cooperating with the limiting protrusion 225 allows the cleaning component 223 to move within the mounting groove 222 according to a preset travel range. Through cooperation with the first spring assembly, the cleaning component 223 can adaptively adjust the distance it moves within the mounting groove 222, thereby ensuring stable and powerful contact between the cleaning component 223 and the bottom of the hopper 11, thus ensuring the effective operation of scraping material from the bottom of the hopper 11.

[0058] like Figure 4 As shown, limiting protrusions 225 are provided on both side walls. The limiting protrusions 225 are located near the second end. The dimensions of the cleaning end 226 and the connecting end 227 along the moving direction are larger than the dimensions of the middle part of the cleaning component 223. The two sides of the cleaning end 226 are respectively limited and engaged with the two limiting protrusions 225. The two sides of the connecting end 227 are respectively limited and engaged with the two limiting protrusions 225. In this embodiment, by setting the dimensions of the cleaning end 226 and the connecting end 227 along the moving direction to be larger than the dimensions of the middle part of the cleaning component 223, there is redundant space in the middle part of the cleaning component 223. This allows the limiting protrusions 225 on the two side walls to be accommodated in the middle part of the cleaning component 223, ensuring that the two sides of the cleaning end 226 and the connecting end 227 are subject to the action of the limiting protrusions 225. This prevents the cleaning component 223 from shifting or derailing during its movement within the mounting groove 222, ensuring the continuity and stability of the movement of the cleaning component 223.

[0059] like Figure 1 and Figure 2As shown, the scraper cleaning device also includes a first vibrating element 40, which is oscillatingly mounted on the frame 10 along the extension direction of the hopper 11. The first vibrating element 40 has a first vibrating end 41, which is located on the outside of the hopper 11 and is used to strike the side wall of the hopper 11. In addition, a driving protrusion 228 is provided on the cleaning plate 22, which is located on the side wall of the cleaning plate 22 along the width direction of the hopper 11. The first vibrating element 40 also has a driving end 42. The bottom surface of the hopper 11 has a clearance groove 14, which is located near the side wall of the hopper 11 and extends along the extension direction of the hopper 11. The first vibrating element 40 passes through the clearance groove 14, and the driving end 42 is located inside the hopper 11. The driving protrusion 228 cooperates with the driving end 42 to drive the first vibrating element 40 to oscillate.

[0060] In the embodiments of this application, the clearance groove 14 on the bottom surface of the hopper 11 provides space for the installation of the first vibrating member 40. Furthermore, it allows the first vibrating end 41 of the first vibrating member 40 to directly strike the bottom surface of the hopper 11, causing the material adhering to the bottom of the hopper 11 to separate from the bottom of the hopper 11 through the vibration of the first vibrating end 41. This assists the cleaning plate 22 in removing the adhering material, thereby improving the efficiency of cleaning the material adhering to the bottom of the hopper 11. Additionally, the cleaning plate 22 has a driving protrusion 228 on its side wall along the width direction of the hopper 11. The driving protrusion 228 can cooperate with the driving end 42 of the first vibrating member 40. When the driving protrusion 228 of the cleaning plate 22 moves to contact the driving end 42, it causes the first driving member to swing, thereby causing the first vibrating end 41 to strike the bottom surface of the hopper 11, thus assisting in cleaning the material adhering to the bottom of the hopper 11.

[0061] In other embodiments of this application, the scraper cleaning device includes a plurality of first vibrating elements 40, which are oscillatingly spaced on the frame 10 along the extending direction of the hopper 11. With this arrangement, each time the driving protrusion 228 of the cleaning element 223 contacts one of the first vibrating elements 40, the first vibrating element 40 strikes the bottom of the hopper 11 once. By having the cleaning element 223 contact multiple first vibrating elements 40 in one stroke, thus striking the bottom of the hopper 11 multiple times, the material adhering to the bottom of the hopper 11 is ensured to loosen and detach, thereby improving the effect of the first vibrating elements 40 in assisting the separation of material from the bottom of the hopper 11, and further improving the efficiency of separating material adhering to the bottom of the hopper 11.

[0062] like Figure 1 and Figure 2As shown, the scraper cleaning device also includes a support shaft 43 and a second elastic element. The support shaft 43 is located outside the hopper 11 and at the bottom of the hopper 11. The middle part of the first vibrating element 40 is located on the support shaft 43. The second elastic element is located between the support shaft 43 and the first vibrating element 40. The first vibrating element 40 has a power storage state and a striking state that are arranged opposite to each other. When the driving protrusion 228 abuts against the driving end 42 and drives the driving end 42 to move, the first vibrating element 40 is in the power storage state. When the driving protrusion 228 separates from the driving end 42, the first vibrating element 40 swings in the opposite direction to switch to the striking state, and the first vibrating end 41 strikes the bottom of the hopper 11.

[0063] In this embodiment, the support shaft 43 located on the bottom side of the outer side of the hopper 11 provides support for the first vibrating element 40. Furthermore, the second elastic element stores and releases elastic potential energy. When the driving protrusion 228 abuts against the driving end 42 and drives the driving end 42 to move, the second elastic element deforms and stores elastic potential energy, thus putting the first vibrating element 40 in a charged state. When the driving protrusion 228 separates from the driving end 42, the second elastic element deforms again and releases elastic potential energy, causing the first vibrating element 40 to move back to its initial position and switch to a striking state. This causes the first vibrating end 41 to strike the bottom of the hopper 11, assisting in cleaning materials adhering to the bottom of the hopper 11. In other embodiments of this application, the second elastic element can be a return spring.

[0064] like Figure 1 and Figure 3 As shown, the scraper cleaning device also includes a discharge cylinder 15 and a second vibrating element 50, which are detachably mounted on the frame 10 and located at the discharge port 13. The second vibrating element 50 is oscillatingly mounted on the frame 10 along the extension direction of the hopper 11. The second vibrating element 50 has a second vibrating end located on the outside of the hopper 11 and is used to strike the side wall of the discharge cylinder 15. In this embodiment, the discharge cylinder 15 is located at the discharge port 13 to guide the movement direction of the material after it leaves the discharge port 13, so that the material moves accurately to a preset range after leaving the discharge port 13, facilitating subsequent material transfer or processing. The arrangement of the second vibrating element 50 allows the side wall of the discharge cylinder 15 to be struck by the second vibrating end of the second vibrating element 50, reducing material adhesion inside the discharge cylinder 15 and preventing discharge blockage or obstruction. The detachable arrangement of the discharge cylinder 15 makes it easy to clean or replace it periodically, ensuring the long-term stable operation of the scraper cleaning device.

[0065] In other embodiments of this application, the inner diameter of the discharge cylinder 15 gradually decreases in the direction away from the bottom of the hopper 11. The structure of the second vibrating member 50 can be the same as that of the first vibrating member 40. The scraper cleaning device also includes a third elastic member, which enables the second vibrating member 50 to have a striking state and a power storage state. When the third elastic member deforms and stores elastic potential energy, the second vibrating member 50 is in a power storage state. When the third elastic member deforms again and releases elastic potential energy, the second vibrating member 50 moves back to its initial position and switches to a striking state, thereby causing the second vibrating end to strike the side wall of the discharge cylinder 15, thereby reducing the material adhering to the side wall of the discharge cylinder 15.
