Description

Technical Field

[0001] This utility model relates to the field of conveyor components, and in particular to a coal sweeper for belt conveyors. Background Technology

[0002] Belt conveyors are essential tools for transporting coal in coal mines. During coal transport, coal easily adheres to the surface of the conveyor belt. Therefore, after the drums rotate, a coal scraper is usually used to remove the surface coal. As shown in the structure of a coal scraper at the head of a coal conveyor belt disclosed in utility model patent application number 20221044733.1, a scraper is bolted to a support rod. A spring or counterweight provides rotational power to the support rod, ensuring the scraper remains in contact with the belt and thus scrapes away the coal from its surface.

[0003] During the use of this type of coal sweeper, the applicant found that the scraper, as a consumable part, needs to be replaced periodically. The existing scraper is fixed to the support rod with multiple bolts. Disassembly requires removing each bolt individually, and installation requires aligning each bolt with the mounting holes on the scraper and the support rod before tightening, making the operation quite difficult. Furthermore, the scraper is mostly made of elastic materials such as polyurethane or plastic, and the bolted areas are prone to shearing and tearing under long-term vibration and friction. Some scrapers have a vulcanized metal plate on the inside, with bolts securing the metal plate to prevent tearing, but this method further increases the cost of the scraper. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a coal sweeper for belt conveyors, which effectively solves the existing problems by optimizing the scraper installation structure.

[0005] To address the aforementioned problems, this utility model provides a coal sweeper for a belt conveyor, comprising a scraper and a mounting frame. The scraper has a deformation groove at its bottom, and the mounting frame has a mounting groove for inserting the bottom of the scraper. A fixing block is provided within the mounting groove. The fixing block is slidably movable between a locked position and an unlocked position along the direction of entering and exiting the mounting groove. When the fixing block is in the unlocked position, the bottom of the scraper can be inserted into the mounting groove, and the fixing block is inserted into the interior of the deformation groove. When the fixing block moves from the unlocked position toward the inside of the mounting groove to the locked position, the fixing block can press against the groove wall of the mounting groove to fix the bottom of the scraper. The coal sweeper also includes a screw connecting the mounting frame and the fixing block. The screw extends out of the outside of the mounting frame and can drive the fixing block to move toward the locked position.

[0006] Furthermore, the fixing block includes an upper block and a lower block connected to the lower side of the upper block. The lower block is connected to the screw, and the upper block can extend into the deformation groove of the scraper. The width of the lower block is greater than the width of the upper block. A nut is screwed onto the portion of the screw outside the mounting bracket.

[0007] Furthermore, the top of the fixing block is provided with an enlarged portion, which can extend outward from the outside of the mounting bracket when the fixing block is in the unlocked position.

[0008] Furthermore, the enlarged portion is provided with a rounded chamfer.

[0009] Furthermore, the edge of the mounting groove is provided with a guide slope.

[0010] Furthermore, the inner surface of the deformation groove is provided with an arc-shaped groove corresponding to the position of the enlarged part.

[0011] Furthermore, the mounting bracket is provided with a plurality of fixing blocks spaced apart along its length, and the lower section inside the mounting groove is provided with a partition rib between adjacent fixing blocks.

[0012] Furthermore, the scraper is configured as a polyurethane scraper.

[0013] The beneficial effect of this utility model is that it effectively solves the existing problems by optimizing the installation structure of the scraper. Attached Figure Description

[0020] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In this utility model, 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 unit; 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.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] In this utility model, such as Figures 1 to 4As shown, a coal sweeper for a belt conveyor is provided, including a scraper 1 and a mounting frame 2. The scraper 1 has a deformation groove 3 at its bottom. The mounting frame 2 has a mounting groove 4 for the bottom of the scraper 1 to be inserted. A fixing block 5 is provided in the mounting groove 4. The fixing block 5 can slide in a locked position and an unlocked position along the direction of entering and exiting the mounting groove 4. When the fixing block 5 is in the unlocked position, the bottom of the scraper 1 can be inserted into the mounting groove 4 and the fixing block 5 is inserted into the interior of the deformation groove 3. When the fixing block 5 moves from the unlocked position toward the inside of the mounting groove 4 to the locked position, the fixing block 5 can press and fix the bottom of the scraper 1 against the groove wall of the mounting groove 4.

[0025] The coal sweeper also includes a screw 6 connected between the mounting frame 2 and the fixing block 5. The screw 6 extends out of the outside of the mounting frame 2 and can drive the fixing block 5 to move toward the locking position.

[0026] During installation, the coal sweeper of this invention uses a screw 6 to move the fixing block 5 to the unlocked position. At this point, the bottom of the scraper 1 can be inserted into the mounting groove 4, while the upper part of the fixing block 5 extends into the inner side of the deformation groove 3. Then, the screw 6 moves the fixing block 5 towards the inner side of the mounting groove 4. As the mounting groove 4 moves inward, it gradually presses and fixes the wall of the deformation groove 3 within the mounting groove 4, thus securing the scraper 1. When it is necessary to remove the scraper 1, simply use the screw 6 to move the fixing block 5 towards the outer side of the mounting groove 4 to release the portion of the scraper 1 that was pressed against the groove wall of the mounting groove 4.

[0027] The beneficial effect of this utility model is that when disassembling the scraper 1, it is not necessary to completely remove the screw 6; simply rotating the screw 6 allows the fixing block 5 to move outward from the mounting groove 4. When installing the scraper 1, simply insert the scraper 1 into the mounting groove 4 and insert the top of the fixing block 5 into the deformation groove 3, then rotate the screw 6 to move the fixing block 5 inward from the mounting groove 4.

[0028] Furthermore, in the application of this utility model, compared with the scraper 1 of the prior art, the scraper 1 of this utility model does not need to be opened for fixing holes, and the existing scraper 1 can be used directly, which reduces the modification cost of processing the scraper 1.

[0029] In a preferred embodiment, more specifically regarding the structure of this utility model, the fixing block 5 includes an upper block 501 and a lower block 502 connected to the lower side of the upper block 501. The lower block 502 is connected to the screw 6, and the upper block 501 can extend into the deformation groove 3 of the scraper 1. The width of the lower block 502 is greater than the width of the upper block 501, and the screw 6 is screwed with a nut 7 on the outer side of the mounting bracket 2.

[0030] As shown in the figure, this configuration allows the lower block 502 to have sufficient lateral dimensions for connection with the screw 6, and also reduces the width of the upper block 501 to facilitate the connection between the upper block 501 and the deformation groove 3 of the scraper 1.

[0031] As shown in the figure, this allows the screw 6 to move outward when the nut 7 is rotated, causing the screw 6 to move towards the inside of the mounting groove 4. When it is necessary to disassemble the scraper 1, the nut 7 can be rotated outward, allowing the fixing block 5 to move towards the outside of the mounting groove 4. At this time, the scraper 1 can be pulled outward, which will move the scraper 1 and the fixing block 5 outward together. After the fixing block 5 moves to the unlocked position, the scraper 1 can be separated from the fixing block 5.

[0032] In a preferred embodiment, specifically regarding the structure of this utility model, the top of the fixing block 5 is provided with an enlarged portion 8. When the fixing block 5 is in the unlocked position, the enlarged portion 8 can extend outward from the outside of the mounting bracket 2. As shown in the figure, by providing the enlarged portion 8, the stability of the squeezing and fixing of the scraper 1 against the groove wall of the mounting groove 4 can be increased when the enlarged portion 8 enters the inner side of the mounting groove 4.

[0033] In a preferred embodiment, more specifically regarding the structure of this utility model, the enlarged portion 8 is provided with a rounded chamfer. As shown in the figure, by providing a rounded chamfer to the enlarged portion 8, the enlarged portion 8 is made to be ellipsoidal in shape, which facilitates the entry of the enlarged portion 8 into the deformation groove 3 and also reduces the shearing damage of the edge of the enlarged portion 8 to the scraper 1.

[0034] In a preferred embodiment, specifically regarding the structure of this invention, the edge of the mounting groove 4 is provided with a guide slope 9. This reduces the difficulty of inserting the scraper 1 into the mounting groove 4.

[0035] In a preferred embodiment, specifically regarding the structure of this utility model, the inner surface of the deformation groove 3 is provided with an arc-shaped groove 10 corresponding to the position of the enlarged part 8. As shown in the figure, this can increase the deformation difference of the groove wall of the deformation groove 3 at the position of the enlarged part 8 and the lower side position of the enlarged part 8 when the enlarged part 8 presses and fixes the groove wall portion of the deformation groove 3, so as to further prevent the scraper 1 from falling out of the mounting groove 4.

[0036] In a preferred embodiment, more specifically regarding the structure of this utility model, the mounting frame 2 is provided with a plurality of fixing blocks 5 spaced apart along its length, and the lower section inside the mounting groove 4 is provided with a partition rib 11 between adjacent fixing blocks 5.

[0037] As shown in the figure, each fixing block 5 is equipped with a screw 6, which allows the fixing blocks 5 to be moved one by one when installing the scraper 1, reducing the difficulty of moving the fixing blocks 5. The partition ribs 11 also prevent the fixing blocks 5 from shifting laterally.

[0038] In a preferred embodiment, specifically regarding the structure of this invention, the scraper 1 is configured as a polyurethane scraper 1. As shown in the figure, this invention uses a fixing block 5 to press and fix the scraper 1. Compared to the prior art method of opening fixing holes in the scraper 1, the technical solution of directly using a polyurethane scraper 1 can prevent the scraper 1 from tearing at the fixing hole position, eliminating the need to reinforce the bottom of the scraper 1 with a metal plate or other means, thus reducing the processing cost of the scraper 1.

[0039] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0040] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
