[0022] The reinforcement mechanism 2 includes a reinforcement groove 201, which is respectively opened at the top of the inner cavity of the first wear-resistant plate 101 and the second wear-resistant plate 102. The inner cavity of the reinforcement groove 201 is movably connected with a connecting plate 203, and the bottom of the connecting plate 203 is fixedly connected with the reinforcement plate 202. One side of the reinforcement plate 202 is tightly fitted with the surface of the first wear-resistant plate 101 and the second wear-resistant plate 102 respectively.

The bottom of the fixing block 206 is tightly fitted with the top of the connecting plate 203, and the surface of the fixing block 206 is movably connected with the inner cavity of the reinforcement groove 201. The setting of the positioning screw 205 guides the movement of the fixing block 206 to prevent the position of the fixing block 206 from shifting during the movement. The setting of the fixing block 206 fixes the top of the connecting plate 203 to prevent the connecting plate 203 from detaching from the inside of the reinforcement groove 201.

[0024] Reference Figure 3The top of the fixed block 206 is movably connected with a nut 204, and the inner cavity of the nut 204 is threadedly connected to the surface of the positioning screw 205. Through the setting of the nut 204, the fixed block 206 is positioned to prevent the fixed block 206 from detaching from the surface of the positioning screw 205.

[0025] Reference Figure 1 , Figure 2 and Figure 4 A positioning mechanism 3 is installed on one side of the fixed block 206, and the positioning mechanism 3 includes a positioning plate 301 and a plug-in slot 302.

[0027] Working principle: First, install the first wear-resistant plate 101 and the second wear-resistant plate 102 on the inner wall of the coal bunker, hold the fixing bolt 103 and rotate it, insert the fixing bolt 103 into the inside of the first wear-resistant plate 101 and the second wear-resistant plate 102, fix the first wear-resistant plate 101 and the second wear-resistant plate 102 to the inner wall of the coal bunker, and then push the reinforcement plate 202 to move, and the movement of the reinforcement plate 202 drives the connection plate 203 to move. When the bottom of the connection plate 203 is attached to the bottom of the inner cavity of the reinforcement groove 201, the reinforcement plate 202 can be attached to the connection between the first wear-resistant plate 101 and the second wear-resistant plate 102, so as to The connection between the first wear-resistant plate 101 and the second wear-resistant plate 102 is reinforced. At the same time, the positioning screw 205 is driven to move during the movement of the connecting plate 203. When the connecting plate 203 is in place, the fixing block 206 is held and moved downward. During the movement of the fixing block 206, the fixing block 206 slides on the surface of the positioning screw 205 until the bottom of the fixing block 206 is attached to the top of the connecting plate 203, thereby fixing the position of the connecting plate 203 to prevent the connecting plate 203 from detaching from the inside of the reinforcement groove 201. The nut 204 is held and rotated to sleeve the nut 204 on the surface of the positioning screw 205 until the nut 204 is fixed. The bottom of the fixing block 206 fits tightly with the top of the fixing block 206, so that the fixing block 206 can be positioned to prevent the fixing block 206 from being separated from the surface of the positioning screw 205, and the positioning plate 301 will be driven to move during the movement of the fixing block 206, and the plug-in board 304 will be driven to move by the movement of the positioning plate 301. When the fixing block 206 is in place, the surface of the plug-in board 304 will be plugged into the inside of the plug-in slot 302, so as to improve the stability of the connection between the first wear-resistant plate 101 and the second wear-resistant plate 102, and when the plug-in board 304 is inside the plug-in slot 302, the damping sleeve 303 on the surface of the plug-in board 304 will increase The friction force exerted on the plug-in board 304 when in contact with the plug-in slot 302 can improve the fixing effect of the plug-in board 304 and prevent the plug-in board 304 from detaching from the inside of the plug-in slot 302, thereby completing the overall reinforcement between the first wear-resistant plate 101 and the second wear-resistant plate 102. Moreover, both the first wear-resistant plate 101 and the second wear-resistant plate 102 are made of high-strength polytetrafluoroethylene PVF. Since the high-strength polytetrafluoroethylene PVF itself has extremely high wear resistance, excellent chemical corrosion resistance and extremely low friction coefficient, and excellent self-lubricating properties, it can improve the wear resistance of the wear-resistant plate material, thereby improving the overall service life of the first wear-resistant plate 101 and the second wear-resistant plate 102.
