Description

Technical Field

[0001] The utility model relates to the field of coal retaining plates, in particular to a coal retaining plate with an anti-scratch effect. Background Art

[0002] The conveyor is a key piece of equipment for coal transportation in fully mechanized mining face operations. The conveyor's coal baffles are used to block the coal, ensuring its proper transport. These baffles are typically connected to connecting plates, making them a crucial component of the conveyor's coal baffles.

[0003] After the existing coal baffle plate and the connecting plate are connected, the connecting plate is usually protruding compared to the coal baffle plate. Therefore, during the coal transportation process, large pieces of coal and gangue often scrape the connecting plate at the coal baffle plate, causing the connecting plate to deform. When the connecting plate is deformed, it will affect the dragging of the coal mining machine cable clamp, thereby causing the coal mining machine to be unable to cut coal normally. In addition, when large pieces of coal and gangue collide with the connecting plate, since the connecting plate is protruding compared to the coal baffle plate, it is easy to cause the large pieces of coal and gangue to get stuck, thereby affecting the normal transportation of coal.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 5 As shown, a coal blocker with an anti-scratch effect includes a first connecting plate 1, a second connecting plate 2, and a coal blocker 3. The coal blocker 3 is installed between the first connecting plate 1 and the second connecting plate 2. A fixing seat 4 is provided on the coal blocker 3. Adjacent coal blockers 3 are respectively provided with an anti-scratch structure 5 and a closing assembly 6 through the fixing seat 4. The fixing seat 4 is provided with a connecting hole, and the coal blocker 3 is provided with a through hole 7. A connecting bolt 8 is provided on the first connecting plate 1, and the end of the connecting bolt 8 passes through the through hole 7 and the second connecting plate 2. The end of the connecting bolt 8 is provided with a nut.

[0021] When installing and connecting the coal baffle 3 on the conveyor, the coal baffle 3 is placed between the first connecting plate 1 and the second connecting plate 2. The ends of the connecting bolts 8 are sequentially inserted through the first connecting plate 1, the through-holes 7, and the second connecting plate 2. Nuts are then installed at the ends of the connecting bolts 8 to secure the coal baffle 3. After the coal baffle 3 is installed, the anti-scratch structure 5 and the sealing assembly 6 are respectively installed on the coal baffle 3 on both sides of the connecting plate along the direction of coal conveyance through the fixing base 4. After all the anti-scratch structures 5 and sealing assemblies 6 are installed, the conveyor can be put into use. The comprehensive mining working face is in operation, and the conveyor is transporting coal. During this process, the coal blocking plate 3 installed through the connecting plate plays a role in blocking the coal. The anti-scratch structure 5 and the closing component 6 protect the part where the connecting plate is connected to the coal blocking plate 3, preventing larger coal blocks from getting stuck in the protruding first connecting plate 1, thereby ensuring the normal transportation of the coal. At the same time, the anti-scratch structure 5 guides the coal to the center, preventing the coal from scratching and getting stuck on the first connecting plate 1, thereby ensuring the integrity of the first connecting plate 1 and further ensuring the normal progress of the coal transportation work.

[0022] According to the above embodiment, the anti-scratch structure 5 includes a mounting rod 501, a mounting bolt 502, a protective plate 503, a screw hole 504, and a buffer assembly 505. The mounting rod 501 is fixed to the fixing base 4 via the mounting bolt 502. The protective plate 503 is rotatably mounted on the mounting rod 501. The screw hole 504 is provided in the protective plate 503. The end of the buffer assembly 505 is connected to the screw hole 504 in the protective plate 503, and the end of the buffer assembly 505 abuts against the first connecting plate 1. The buffer assembly 505 includes a connecting block 5051, a threaded joint 5052, a special-shaped abutting block 5053, and a spring 5054. The connecting block 5051 is fixedly connected to the threaded joint 5052, and the threaded joint 5052 is connected to the screw hole 504. The special-shaped abutting block 5053 is provided with a round rod. One end of the spring 5054 is connected to the round rod, and the other end of the spring 5054 is connected to the connecting block 5051.

[0023] The closing assembly 6 includes a mounting plate 601, a closing plate 602 and a rubber strip 603. The mounting plate 601 is fixedly connected to the closing plate 602, and the mounting plate 601 is fixedly mounted on the fixing seat 4 by screws. The rubber strip 603 is arranged on the inner side of the mounting plate 601, and the rubber strip 603 contacts the first connecting plate 1.

[0024] It should be noted that by providing a fixing seat 4 on the coal-blocking plate 3 and providing an anti-scratch structure 5 and a closing assembly 6 on both sides of the connecting plate along the forward direction of the coal, the connecting plate can be protected. The anti-scratch structure 5 is provided with a protective plate 503, which can also guide the coal and guide the coal to the middle part of the conveyor, thereby ensuring the stability of the conveying. A buffer assembly 505 is provided on the protective plate 503. When the coal hits the protective plate 503, the protective plate 503 rotates on the mounting rod 501 and cooperates with the buffer assembly 505 to form a buffer. While ensuring the guiding effect, it can avoid damage caused by the collision and ensure the integrity of the protective plate 503. The buffer assembly 505 is installed in a threaded connection manner, which is convenient for disassembly and replacement.

[0025] When installing the anti-scratch structure 5, the mounting rod 501 is fixed to the corresponding fixing seat 4 by means of the mounting bolt 502, and the entire buffer assembly 505 is mounted to the protective plate 503 by means of the threaded joint 5052, thereby completing the installation of the anti-scratch structure 5. When installing the closing assembly 6, the mounting plate 601 is fixed to the fixing seat 4 by means of screws, and the closing plate 602 closes the connection between the first connecting plate 1 and the corresponding coal blocking plate 3. At this time, the rubber strip 603 contacts the first connecting plate 1. During coal conveying, the guard plate 503 cooperates with the closing plate 602 to protect the connection between the first connecting plate 1 and the coal retaining plate 3. When the first guard plate 503 is struck by coal, it rotates on the mounting rod 501, thereby causing the connecting block 5051 to flip toward the first connecting plate 1. During this process, the spring 5054 deforms under the limiting action of the special-shaped abutment block 5053. The spring 5054 is compressed to absorb kinetic energy, thereby providing a buffering and supporting effect, ensuring the integrity of the guard plate 503. At the same time, during coal conveying, the spring 5054 cooperates with the guard plate 503 to be relatively tilted, guiding and centering the coal, allowing the coal to be transported in the middle of the conveyor, further preventing the coal from hitting the first connecting plate 1 and ensuring the integrity of the first connecting plate 1.
