Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to a conveyor scraper and a scraper conveyor. Background Technology

[0002] Scraper conveyors are a type of continuous conveying equipment widely used in various industrial fields. They are mainly used for conveying bulk materials over short distances and can meet horizontal, inclined, and even vertical conveying needs. Therefore, they are widely used in industries such as mining, coal, chemical, grain processing, and building materials.

[0003] The main components of a scraper conveyor include the casing, scraper chain, drive unit, tensioning device, and inlet and outlet. The casing, typically made of steel plate, holds the material and protects the internal chain and scrapers. The scraper chain propels the material. The drive unit, including an electric motor and reducer, provides the necessary power to the conveyor. The tensioning device ensures the chain maintains proper tension for smooth operation. Its working principle relies on scrapers fixed to the chain, which, within the enclosed casing, continuously transports material from one location to another through the chain's traction. Scraper conveyors are characterized by their simple structure, large conveying capacity, flexible conveying distance, good sealing, and wide applicability.

[0004] However, the fixed specifications of the scrapers inside traditional conveyors limit the transport capacity of the device, affecting its actual transport volume and efficiency. Summary of the Invention

[0005] This invention addresses the problem of fixed scraper size in current scraper conveyors, which limits conveying efficiency, by providing a new type of scraper for conveyors.

[0006] To address the aforementioned problems, the present invention provides a conveyor scraper comprising a baffle plate with an internal cavity and an opening at the top. An extension plate is installed within the opening, with its upper portion extending above the opening. A pushing mechanism is located at the bottom of the inner wall of the baffle plate, capable of driving the extension plate upwards. This conveyor scraper solution, by providing an opening on the baffle plate and installing a liftable extension plate, increases the area of ​​the conveyor scraper, thereby enhancing the conveying efficiency of the scraper conveyor.

[0007] As a preferred embodiment of a conveyor scraper, the pushing mechanism includes a lead screw disposed at the bottom of the cavity, the lead screw being parallel to the bottom edge of the baffle plate, and a push block threaded onto the lead screw. The top surface of the push block has a first inclined surface, and the bottom surface of the riser plate has a second inclined surface, with the first and second inclined surfaces abutting against each other. Through the cooperation of the lead screw and the inclined surfaces, the lateral drive of the lead screw is converted into a vertical push, and the lead screw structure achieves self-locking in the height direction, preventing the riser plate from descending.

[0008] As a preferred embodiment of a conveyor scraper, the pusher block has a movable guide block at its bottom, and the inner wall of the baffle plate's cavity has a movable groove parallel to the lead screw, with the movable guide block located within the movable groove. This makes the lateral movement of the pusher block more stable.

[0009] As a preferred embodiment of a conveyor scraper, multiple push blocks are provided, all mounted on the lead screw, and the bottom of the riser plate has a second inclined surface corresponding to the number of push blocks. This allows for more balanced lifting and lowering of the riser plate in the lateral direction.

[0010] As a preferred embodiment of a conveyor scraper, the bottom of the baffle plate is provided with a guide block, and the lower part of the guide block has a triangular notch, with the second inclined surface being one side of the triangular notch. The triangular notch increases the lifting range.

[0011] As a preferred embodiment of a conveyor scraper, one end of the lead screw is located on the surface of the baffle plate, and this end is provided with a rotating groove.

[0012] As a preferred embodiment of a conveyor scraper, the top edge of the riser plate is provided with anti-collision cones. The anti-collision cones at the top of the riser plate, through their oblique angle, reduce impact on the conveyed material and minimize material breakage.

[0013] As a preferred embodiment of a conveyor scraper, the bottom front of the baffle plate is provided with a lower shovel edge, which is connected to the front of the baffle plate via a first arc-shaped groove. The front of the baffle plate is also provided with several second arc-shaped grooves. The shovel-shaped structure at the bottom of the baffle plate improves conveying efficiency.

[0014] As a preferred embodiment of a conveyor scraper, the front two vertical sides of the baffle plate are also provided with side baffles. The forward-extending side baffles form a bucket-like structure, which reduces the loss of conveyed material to both sides and further improves conveying efficiency.

[0015] On the other hand, this utility model also provides a scraper conveyor, including a body, a circulating chain on the body, and the aforementioned conveyor scraper mounted on the circulating chain. This scraper conveyor, with the aforementioned conveyor scraper, offers flexible and adjustable conveying efficiency and is more convenient to use.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are as follows: First, by setting an opening on the baffle plate and installing a liftable extension plate, the conveying area of ​​the scraper conveyor is successfully increased, thereby significantly improving the conveying efficiency. Second, the ingenious cooperation between the screw and the inclined plane achieves vertical pushing and has a self-locking function, preventing the extension plate from falling unexpectedly and ensuring the stability of the conveying process. In addition, the design of the moving guide block and the moving chute makes the lateral movement of the push block more stable, and multiple push blocks are evenly distributed on the screw, ensuring the balance of the extension plate's lifting and lowering. The design of the guide block and the triangular notch increases the lifting range and improves the adaptability of the equipment. The setting of the rotating groove makes operation more convenient. The anti-collision cone reduces material damage, and the shovel-shaped structure and side baffles further improve the conveying efficiency and prevent material loss. Finally, the scraper conveyor provided by this utility model, due to these innovative designs, makes the conveying efficiency flexibly adjustable and more convenient to use.

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] Example 1:

[0028] This embodiment provides a conveyor scraper, such as Figure 1 , 2 As shown, it includes a baffle plate 3, and a heightening plate 4 is slidably connected to the upper half of the baffle plate 3. Specifically, the baffle plate 3 has a cavity inside, and the cavity has an opening at the top of the baffle plate 3. The heightening plate 4 is installed in the opening, and the upper part of the heightening plate 4 is higher than the opening. A pushing mechanism is provided at the bottom of the inner wall of the baffle plate 3, and the pushing mechanism can drive the heightening plate 4 to rise.

[0029] Combination Figure 3-5 The pushing mechanism includes a lead screw 9 disposed at the bottom of the cavity, the lead screw 9 being parallel to the bottom edge of the baffle plate 3. Several guide blocks 5 are mounted on the lower surface of the lead screw 9 and the raising plate 4. Each guide block 5 has a triangular notch at its lower part, within which a push block 6 is disposed. The top surface of the push block 6 has a first inclined surface, and one side of the triangular notch at the lower part of the guide block 5 forms a second inclined surface. The first and second inclined surfaces are abutted against each other. The lower part of the push block 6 is threadedly connected to the lead screw 9. A movable guide block 7 is also disposed on one side of the push block 6. The inner wall of the cavity of the baffle plate 3 has a movable slide groove 8, which is parallel to the lead screw 9. The movable guide block 7 is located in the movable slide groove 8 and can move along the movable slide groove 8. A window communicating with the inner cavity is opened on the side of the baffle plate 3. One end of the lead screw 9 is located in this window and on the surface of the baffle plate 3. This end of the lead screw 9 has a rotating groove 10. Figure 5 As shown, the rotating groove 10 has an internal hexagonal structure, which can be used with a hexagonal wrench to rotate the lead screw 9.

[0030] The bottom front of the baffle plate 3 is provided with a lower shovel edge 301. The lower shovel edge is connected to the front of the baffle plate 3 through a first arc-shaped groove 302. The front of the baffle plate 3 is also provided with several second arc-shaped grooves 303. The first arc-shaped groove 302 and the second arc-shaped grooves 303 are arc-shaped, and both the first arc-shaped groove 302 and the second arc-shaped grooves 303 are concave inward. The two vertical sides of the front of the baffle plate 3 are also provided with side baffles 304. A ring of cone-shaped edge 305 is provided at the top opening of the baffle plate 3. The top surface of the cone-shaped edge 305 is a beveled surface. The top of the cone-shaped edge 305 gradually approaches the heightening plate 4. The top edge of the heightening plate 4 is provided with anti-collision cone strips 401. The top of the anti-collision cone strips 401 gradually narrows upward. The side baffle 304 is arc-shaped on the side near the baffle plate 3, and the outer end of the inner side of the side baffle 304 is cone-shaped. By using the arc-shaped design of the lower shovel edge 301, the material can be pushed obliquely upwards, moving towards the surface of the baffle plate 3. The layered contact between the first arc-shaped groove 302 and the second arc-shaped groove 303, along with their arc-shaped surface structure, provides a large contact area between the baffle plate 3 and the material, thereby increasing friction and preventing the material from moving out of the pushing range of the baffle plate 3. Furthermore, the conical guidance and arc-shaped limiting of the side baffles 304 further limit the material, preventing it from slipping during movement. This increases the volume of material pushed by the baffle plate 3, enhancing the device's ability to move material and ensuring the strength of each material movement. The tight guidance of the cone edge 305 limits any residual material on the surface of the riser plate 4, preventing it from flowing into the baffle plate 3. The conical guidance of the anti-collision cone strip 401 provides an inclined guide for the material's movement, preventing direct impact on the riser plate 4 and thus preventing damage.

[0031] Example 2

[0032] This embodiment further provides a coal mine scraper conveyor, such as... Figure 6 As shown, the device includes a body 1, inside which two circulating chains 2 are installed, and between the two circulating chains 2 are several baffles 3 provided in Embodiment 1. The bottom ends of the baffles 3 are respectively connected to the links of the two circulating chains 2.

[0033] In this invention, the stable transport of materials within the machine body 1 is ensured by connecting multiple baffles 3 with the circulating chains 2 on both sides. By rotating the lead screw 9, multiple moving guide blocks 7 move simultaneously, causing multiple push blocks 6 to push the guide block 5 sequentially. Based on the inclined structure of the push block 6 itself, the guide block 5 is pushed, resulting in a height movement that moves the lifting plate 4 out of the guide block 5. The lifted plate 4 is then used in combination with the baffles 3 to increase the contact area with the material, thereby increasing the volume of material pushed by the lifting plate 4 and the baffles 3 in a single movement. This improves the single-time support capacity of the device. By adjusting the lifting plate 4 to different degrees, different combinations of the baffles 3 and the lifting plate 4 can be selected, allowing the device to have multiple pushing areas and adjustable support for various pushing amounts. Simultaneously, with multiple spring limit connections between the lifting plate 4 and the baffles 3, the lifting plate 4 moves stably while also having an automatic reset effect.

[0034] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: First, by setting an opening on the baffle plate and installing a liftable extension plate, the conveying area of ​​the scraper conveyor is successfully increased, thereby significantly improving the conveying efficiency. Second, the ingenious cooperation between the screw and the inclined plane achieves vertical pushing and has a self-locking function, preventing the extension plate from falling unexpectedly and ensuring the stability of the conveying process. In addition, the design of the moving guide block and the moving chute makes the lateral movement of the push block more stable, and multiple push blocks are evenly distributed on the screw, ensuring the balance of the extension plate's lifting and lowering. The design of the guide block and the triangular notch increases the lifting range and improves the adaptability of the equipment. The setting of the rotating groove makes operation more convenient. The anti-collision cone reduces material damage, and the shovel-shaped structure and side baffles further improve the conveying efficiency and prevent material loss. Therefore, the scraper conveyor provided by this utility model, due to these innovative designs, makes the conveying efficiency flexibly adjustable and more convenient to use.
