Technical Field

[0001] The utility model relates to the technical field of coal mine auxiliary tools, in particular to a detachable and maintainable machine plate of a coal mine conveyor. Background Art

[0002] Coal mine conveying equipment is an important auxiliary tool in coal mining and processing. It can transport and concentrate the mined coal and is an indispensable tool in coal mining processing.

[0003] At present, the commonly used conveyors in coal mining and transportation are conveyor belt conveyors, scraper conveyors, etc. Among them, the scraper conveyor is more stable in transportation and has better support for coal materials. When the scraper conveyor is in operation, the largest consumption is the machine plate used for scraping and pushing coal, because it has the highest contact with the harder coal raw materials, so its service life is also shorter.

[0004] The existing detachable and maintainable machine plate of the coal mine conveyor has the following disadvantages: the machine plate is easy to wear, has a short life, and the disassembly and replacement structure is not simple enough. Therefore, we propose a detachable and maintainable machine plate of the coal mine conveyor. Utility Model Content

[0009] Furthermore, internal thread seats corresponding to the positions of the bolts are respectively arranged at the middle and both ends of the bottom of the chain through groove.

[0010] Furthermore, the bottom of the bolt is threadedly connected to the internal thread seat.

[0011] Furthermore, the plate seat and the plate cover are both made of stainless steel, and the surfaces of the plate seat and the plate cover are plated with a chrome layer.

[0012] According to the detachable and maintainable machine plate of the coal mine conveyor, a positioning step higher than the bottom surface and lower than the top surface of the plate seat is provided around the chain groove, and a positioning step is contacted with the positioning step around the plate cover.

[0013] According to the detachable and maintainable machine plate of a coal mine conveyor, the middle of the plate seat is concave, and a chain fixing ring is arranged through the chain groove in the middle, the chain fixing ring protrudes from both sides of the plate seat, and reinforcing ribs extending toward the chain groove are arranged on both sides of the concave position.

[0014] Compared with the prior art, the utility model has the following beneficial effects: a coal scraper is formed by a plate seat, a plate cover and bolts, so as to realize a scraper conveyor for coal mining and transportation, and provide a set of coal scraper plates which are convenient to disassemble and replace and stable in pushing coal; the arrangement of the chain threading groove can help the chain threading of the scraper conveyor; the plate cover is set to cover the chain threading groove on the plate seat, and the plate cover and the plate seat are tightened and fixed by bolts to realize the assembly of the whole coal scraper on the chain of the scraper conveyor; during the chain transmission of the scraper conveyor, the coal scraper can follow the chain transmission of the scraper conveyor to scrape and push the coal on the scraper conveyor, so as to transport the coal; through the first material stagnation groove and The setting of the second material retention groove can help more coal to be retained on the inner side of the coal scraper plate, so that the coal scraper plate can push the coal better when the coal scraper plate moves with the chain of the scraper conveyor. The setting of the chrome plating layer can improve the use strength of the scraper plate surface and increase the wear resistance of the scraper plate. When it is necessary to replace one group of scraper plates on the chain of the scraper conveyor separately, the worker removes the bolts on the plate cover and takes the chain of the scraper conveyor out of the chain groove, so as to remove the scraper plate and replace it with a new one. The operation is simple and easy to use, and the problems of inconvenient disassembly, easy wear and short service life of the scraper plate of the existing scraper conveyor used for coal mine transportation are solved.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a detachable and maintainable machine plate of a coal mine conveyor includes a coal scraper plate 1, and the coal scraper plate 1 includes a plate seat 2, a plate cover 3 and a bolt 5. A chain groove 4 is opened in the middle of the top of the plate seat 2, and the plate cover 3 is arranged on the top of the chain groove 4. A first material retention groove 7 and a second material retention groove 8 are opened on both sides of the two ends of the plate seat 2. Bolts 5 are inserted in the middle and both ends of the top of the plate cover 3. Internal thread seats 6 corresponding to the bolts 5 are respectively arranged in the middle and both ends of the bottom of the chain groove 4, and the bottom of the bolt 5 is threadedly connected to the internal thread seat 6.

[0022] The plate seat 2 and the plate cover 3 are both made of stainless steel, and the surfaces of the plate seat 2 and the plate cover 3 are plated with a chrome layer 9; the chrome layer 9 can increase the wear resistance of the surface of the plate seat 2 and the plate cover 3, thereby effectively improving the service life of the coal scraper 1.

[0023] The device is provided with a positioning step higher than the bottom surface and lower than the top surface of the plate seat (2) around the chain through groove (4), and the plate cover (3) contacts the positioning step around the plate seat (2). The positioning step isolates the cover plate from the bottom surface of the plate seat (2) where the chain through groove (4) is located to form a space, and the chain through groove (4) intersects with the space.

[0024] At the same time, the middle of the plate seat (2) is concave, the middle of the space passes through a chain groove (4) and a chain fixing ring is arranged, the chain fixing ring leaks out of both sides of the plate seat, and the chain connects the two ends of the chain fixing ring to form an uninterrupted chain machine plate connected front and back.

[0025] At the same time, reinforcing ribs extending toward the chain passing groove (4) are arranged on both sides of the concave position to strengthen the structural strength of the plate seat at the space where the chain passing groove (4) and the chain fixing ring pass through.

[0026] It should be noted that the utility model is a detachable and maintainable machine plate of a coal mine conveyor. When working, a worker assembles a coal scraper plate 1 on the chain of the scraper conveyor required for operation. During assembly, the chain is placed in the chain groove 4, and then the plate cover 3 is covered on the chain groove 4. The plate cover 3 and the plate seat 2 are tightened and fixed by bolts 5. When the chain of the scraper conveyor is driven, the coal scraper plate 1 can follow the chain of the scraper conveyor to scrape and push the coal on the scraper conveyor to achieve the transportation of the coal. The provision of the first material retention groove 7 and the second material retention groove 8 can help more coal to be retained on the inner side of the coal scraper plate 1, so that the coal scraper plate 1 can better push the coal when the coal scraper plate 1 moves with the chain of the scraper conveyor. The provision of the chrome plating layer 9 can improve the efficiency of the coal scraper plate 1. The surface strength is increased, and the wear resistance of the coal scraper plate 1 is increased. When one group of coal scraper plates 1 on the chain of the scraper conveyor needs to be replaced separately, the worker removes the bolts 5 on the plate cover 3, and the chain of the scraper conveyor can be taken out from the chain groove 4, so that the coal scraper plate 1 can be removed and replaced with a new one. It is flexible and convenient to use.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
