Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a high-strength conveying scraper. Background Art

[0002] Scraper conveyors are commonly used on construction sites for conveying large solid materials. They are primarily used in the construction, mining, and chemical industries. A scraper conveyor consists of a head, tail, center trough, conveyor chain, and several conveyor blades. The blades are connected by the conveyor chain and arranged above the center trough. The head and tail control the movement of the conveyor chain, which in turn drives the conveyor blades. When the scraper conveyor is in use, material is added to the center trough from above the conveyor blades, and the movement of the conveyor blades drives the material along.

[0003] The conveyor scraper is the main part that drives the material to move. It requires a certain degree of rigidity or toughness to ensure that the scraper body is not easily deformed, and a certain load-bearing capacity to bear the weight of the material when moving upward. Common conveyor scrapers often increase their strength by increasing their thickness, but if the conveyor scraper itself is too heavy, it will increase the pressure on the conveyor chain and drive device, reducing the conveying efficiency.

[0004] After searching, the Chinese utility model patent with publication number CN220997967U discloses a high-strength scraper, including a scraper body, a first groove provided on one side of the scraper body, a second groove provided on the other side of the scraper body, a first reinforcing rib provided in the middle of the first groove, and a plurality of second reinforcing ribs provided on both sides of the first reinforcing rib, and the scraper body and the first and second reinforcing ribs are integrally formed. This application improves the toughness of the scraper by providing the first and second reinforcing ribs on the surface of the scraper body, and reduces the weight of the scraper body and improves its toughness by providing the second groove. Although this application provides a technical solution to reduce the weight of the conveyor plate itself, the connection between the chain and the scraper body and the chain itself are exposed, which will be directly affected by the collision and friction of the material, easily wear and tear, and reduce the service life.

[0028] Example 1

[0029] Refer to the attached Figure 1-5 The present application provides a high-strength conveying scraper, including a scraper body 1 used on a scraper conveyor. The scraper body 1 can drive the material to move. The interior of the scraper body 1 is a cavity structure, which can reduce the weight of the scraper body 1. The interior of the scraper body 1 is provided with a reinforcing rib 5. The reinforcing rib 5 can improve the toughness of the scraper body 1. The reinforcing rib 5 is arranged in the cavity along the length direction of the scraper body 1. A first groove is provided at the bottom of the scraper body 1. Preferably, two first grooves can be provided, which need to be symmetrically arranged at the bottom of the scraper body 1. In other embodiments, one first groove can also be provided, which needs to be arranged at the center of the bottom of the scraper body 1. A connecting plate 3 is provided on the side wall of the scraper body 1 in the first groove. The connecting plate 3 is perpendicular to the scraper body 1. The front and rear ends of the connecting plate 3 both extend out of the first groove. The scraper body 1 is connected to the chain of the scraper conveyor through the connecting plate 3. The connecting plate 3 extending out of the first groove is provided with connecting parts 9 at both ends of the plate body outside. The connecting parts 9 are made of rigid material and are detachably connected to the connecting plate 3. The connecting parts 9 can protect the part where the connecting plate 3 is connected to the chain of the scraper conveyor, avoid the connection from being stuck or corroded, and improve the service life and flexibility of the connecting plate 3; a protective cover 8 is provided between the connecting parts 9 on the two adjacent scraper bodies 1, and the connecting parts 9 are detachably connected to the protective cover 8. The protective cover 8 is provided on the chain of the scraper conveyor. The protective cover 8 can protect the chain of the scraper conveyor, avoid the chain from being stuck or corroded, and improve the service life of the chain.

[0030] Preferably, the top of the scraper body 1 is thinner than the bottom, and is configured in an angular shape with a thin top and a thick bottom. The top of the scraper body 1 is tilted forward. When the scraper body 1 drives the material to move horizontally or upward, the bottom bears the greatest pressure from the material. Therefore, the bottom thickness should be greater than the top. The top is configured in an angular shape. This not only reduces the weight of the scraper body 1, but also reduces the contact area between the top of the scraper body 1 and the material. When loading materials from above the center trough of the scraper conveyor, it can reduce the impact of the material on the scraper body 1, reducing the wear of the scraper body 1.

[0031] Preferably, a plurality of partition plates 2 are provided on the front side of the scraper body 1, and the plurality of partition plates 2 are spaced apart along the length direction of the scraper body 1. The partition plates 2 are arranged in an angular shape corresponding to the shape of the scraper body 1. When loading materials from above the middle trough of the scraper conveyor, the partition plates 2 can disperse the materials to both sides, thereby preventing the materials from accumulating in the middle area of the scraper body 1 and causing uneven force on the scraper body 1.

[0032] Preferably, a ribbed partition 6 is provided on the front side of the ribbed plate 5, extending from the front side of the ribbed plate 5 into the interior of the partition plate 2. A cavity structure is provided inside the partition plate 5 to reduce the weight of the partition plate 2 itself. The ribbed partition 6 is arranged in the cavity structure and is integrally formed with the ribbed plate 5. The ribbed partition 6 can improve the toughness of the partition plate 2 and prevent the partition plate 2 from deflecting to the left or right.

[0033] Preferably, the connecting plate 3 extending out of the first groove is provided with a connecting hole 4. A strip-shaped connector is provided at the connecting hole 4. The connector passes through the connecting hole 4, the scraper conveyor chain, and the connecting plate 3 in sequence, rotatably connecting the connecting plate 3 to the scraper conveyor chain. The length of the connector is greater than the width of the first groove, and both ends of the connector protrude from the connecting hole 4, facilitating installation and removal of the connector.

[0034] Preferably, the connector 9 includes two frames with openings facing each other, and the two frames are symmetrically arranged along the vertical axis. A clamp is provided on the outside of the connector 9, and the clamp is used to fix the two frames in connection; second grooves are provided on the inner walls on both sides of the connector 9, and the two second grooves are respectively adapted to the two ends of the connector. When the connector 9 wraps the connecting plate 3 from the left and right sides, the two ends of the connector enter the second grooves respectively. The second grooves limit the relative movement of the connector 9 and the connector, so that the connector 9 is connected to the connecting plate.

[0035] Preferably, the protective cover 8 includes a flexible portion and a rigid portion. The rigid portion ensures the support of the protective cover. In the natural state, the width of the rigid portion is greater than that of the flexible portion. The rigid portion can protect the flexible portion from collision with materials and reduce wear of the flexible portion. The flexible portion ensures that the protective cover has the function of telescopic deformation to prevent the scraper conveyor chain from being obstructed when turning. The flexible portion and the rigid portion are arranged at intervals. The bottom of the protective cover 8 is provided with an opening along the length direction. The protective cover 8 is placed on the scraper conveyor chain from above and below. The rigid portion of the protective cover is tough and can quickly return to a circular shape after deformation, ensuring that the opening of the protective cover 8 is closed in the natural state, preventing materials from entering the protective cover 8 from below. The rigid portion is provided at the port of the protective cover 8. The rear end of the connector 9 is provided with a card interface. The width of the card interface is less than the distance between the side walls of the connector. The protective cover 8 is connected to the connector 9 at the card interface through the rigid portion at the port.

[0036] Preferably, a buffer sleeve is provided on the portion of the connector located in the first groove, and the buffer sleeve is provided on the outside of the connector. The buffer sleeve is made of a tough material. When the scraper conveyor chain drives the scraper body 1 to turn, the connector is subjected to the downward pulling force of the front and rear chains. The addition of a tough buffer sleeve at the contact portion of the connector and the chain can reduce the impact of the chain pulling force on the connector, prevent the connector from breaking or bending, and increase the service life of the connector.

[0037] Working principle: When installing the conveying scraper, first, place the scraper body 1 above the chain of the scraper conveyor, and place the chain through the first groove at the bottom of the scraper body 1. Insert the connector into the connecting hole 4 on one side, the chain, and the connecting hole 4 on the other side in sequence. Then, place the rigid part at the port of the protective cover 8 into the card interface of the connector 9. Note that the side of the protective cover 8 with the opening is placed at the bottom. At the same time, align the two second through holes of the connector 9 with the two ends of the connector respectively, and then merge the two frames of the connector 9. Use a clamp to cover the outside of the connector 9 to connect the two frames of the connector 9 together. Finally, separate the opening at the bottom of the protective cover 8 and put the protective cover 8 downward on the chain of the scraper conveyor.

[0038] Example 2

[0039] Refer to the attached Figure 6 The present application provides a high-strength conveying scraper. Compared with Example 1, in order to further improve the bearing capacity of the scraper body 1, the reinforcing rib plate 5 is a corrugated plate.

[0040] Working Principle: The corrugated plate has a higher load-bearing capacity due to its special shape, which can better improve the toughness of the scraper body 1. Moreover, compared with flat plates or plates with less curvature, the corrugated plate can occupy a larger space in the scraper body 1, which can greatly reduce the weight of the scraper body 1.

[0041] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The scope of protection of the present utility model should be based on the scope of protection of the claims.
