Manufacturers can select coal supporting plate bodies 10 of different lengths according to actual use requirements, and the drooping wear zone 101 is about one meter. The area of ​​the coal supporting plate body 10 located at the rear side of the rear iron stop 20 is a spare zone 102, and the length of the spare zone 102 is determined according to actual requirements. In this embodiment, the length of the spare zone 102 accounts for one third of the total length of the coal supporting plate body 10, and a T-shaped groove 103 is provided at the rear end of the coal supporting plate body 10, and a T-shaped block 201 is fixedly connected to the bottom of the rear iron stop 20, and the rear iron stop 20 slides in the T-shaped groove 103 through the T-shaped block 201, and fixing components are provided on both sides of the coal supporting plate body 10, and the rear iron stop 20 is fixed to the coal supporting plate body 10 through the fixing components;

[0026] Further, the fixing assembly includes two symmetrically arranged male plates 30 and female plates 31. In the present embodiment, the male plates 30 and female plates 31 are semicircular arc plates, and may also be rectangular, waist-shaped, trapezoidal and other structures. Both sides of the coal supporting plate body 10 are provided with a plurality of equally spaced mounting holes 104. One side of the male plates 30 and female plates 31 are fixed with connecting columns 32 located inside the mounting holes 104. A mounting groove 33 is formed between the male plates 30 and female plates 31. The interior of the rear stop iron 20 is slidably connected to a connecting plate 21. The connecting plate 21 is slidably connected to the rear stop iron 20. 1 are fixed with vertical rods 22 at both ends, and the two vertical rods 22 are respectively inserted into the corresponding installation grooves 33. It should be noted that in order to ensure the connection strength between the vertical rod 22 and the connecting plate 21, the materials used for the vertical rod 22 and the connecting plate 21 have a structural hardness greater than or equal to the material hardness of the rear stop iron 20. The end of the vertical rod 22 away from the connecting plate 21 is provided with a connecting hole 221, and a sliding rod 34 penetrating the connecting hole 221 and the female plate 31 is slidably connected to one side of the male plate 30. The end of the sliding rod 34 close to the male plate 30 is coaxially fixed with a connecting platform 35. The connecting platform 35 is connected to the male plate 30 through a spring, a support plate 36 is fixed on the top of the female plate 31, and a limit rod 37 that slides up and down is arranged on the support plate 36, and the limit rod 37 passes through the end of the slide rod 34, and a round table 371 is coaxially fixed to the end of the limit rod 37 close to the support plate 36, and the round table 371 is connected to the support plate 36 through a spring. Through the arrangement of the male plate 30, the female plate 31 and the vertical rod 22, the rear stop 20 can be quickly disassembled without using special tools, and the disassembly work will not be caused by rust. The impact is relatively large. When installing the rear stop 20, pull the connecting platform 35 to drive the slide bar 34 to move to one side, then insert the vertical rod 22 into the installation groove 33, and then align the slide bar 34 with the connecting hole 221 and insert it through one side of the female plate 31. Before the slide bar 34 completely penetrates the female plate 31, pull the round table 371 upward to prevent the limit rod 37 from affecting the movement of the slide bar 34.

At this time, the limit rod 37, the slide bar 34, the vertical rod 22 and the rear stop 20 are completely limited.

[0027] refer to Figure 3 and Figure 5 As shown, considering the problem that the connecting plate 21 is prone to displacement when sliding up and down inside the rear stop iron 20, a rectangular groove 202 is provided inside the rear stop iron 20, and the connecting plate 21 is connected to the rectangular groove 202 by a spring. A plurality of limit grooves are provided inside the rectangular groove 202, and a plurality of limit blocks 211 matching the limit grooves are fixed on both sides of the connecting plate 21, and the limit blocks 211 are slidably connected to the limit grooves. The connecting plate 21 is limited by the setting of the limit grooves, the rectangular groove 202 and the limit blocks 211 to prevent the connecting plate 21 from deflecting.

[0028] refer to Figure 3 and Figure 5 As shown, considering that it is rather laborious to pull the connecting plate 21 upward when disassembling the rear stop 20, and the connecting plate 21 is easily tilted when lifting the connecting plate 21 upward, which affects the up and down sliding of the connecting plate 21, a groove 203 is provided at the top of the rear stop 20, and a vertical hole penetrating into the rectangular groove 202 is provided in the middle of the groove 203, a pull rod 23 located in the vertical hole is fixedly connected to the middle of the connecting plate 21, and a handle 24 located in the groove 203 is fixed at one end of the pull rod 23 away from the connecting plate 21. Through the settings of the handle 24, the groove 203 and the pull rod 23, the worker only needs to hold the handle 24 and pull upward, and the connecting plate 21 can be vertically lifted up, and the whole process is more time-saving and labor-saving.

[0029] refer to Figure 1 As shown, in order to prevent a large amount of dust from accumulating inside the T-slot 103 at the front end of the rear stop 20 , an accordion cover 40 is provided between the T-slot 103 and the rear stop 20 .

[0030] refer to Figure 1 As shown, a cutting line is provided near the sagging wear area 101 of the coal supporting plate main body 10, and the length of the cutting line from the front end of the coal supporting plate is about one meter.

[0031] refer to Figure 3 As shown, in order to facilitate workers to hold the handle 24 , the diameter of the middle portion of the groove 203 is larger than the diameters at both ends. The handle 24 is semicircular, and the diameter of the handle 24 is consistent with the diameters at both ends of the groove 203 .

[0032] refer to Figure 4 As shown, further, in order to better cooperate between the sliding rod 34 and the limiting rod 37, a conical block 341 is provided at the end of the sliding rod 34, the bottom of the limiting rod 37 is spherical, and the bottom of the limiting rod 37 in a static state is higher than the axis of the sliding rod 34. Through the settings of the conical block 341 and the ball head, when the sliding rod 34 moves toward the female plate 31, the conical block 341 slowly contacts the ball head, and the limiting rod 37 moves upward under the squeezing of the conical block 341 until the limiting rod 37 is inserted into the hole opened on the sliding rod 34.

[0033] When the utility model is used:

[0034] First, when the sagging wear area 101 reaches the maximum wear amount, the worker cuts off the front end of the coal supporting plate body 10 according to the pre-set cutting line;

[0035] Then, the support plate 36 is pulled upward to disengage the limit rod 37 from the slide rod 34, and the connecting platform 35 is held and pulled toward the side away from the male plate 30, so that the slide rod 34 and the vertical rod 22 are disengaged from the limit. When the slide rods 34 on both sides are disengaged from the vertical rod 22, the worker holds the handle 24 and pulls it upward, and then pulls the rear stop iron 20 toward the rear end;

[0036] Finally, when installing the rear stop iron 20, pull the positive plate 30 and the negative plate 31 on both sides of the coal supporting plate out of the mounting holes 104, and then insert them into the inside of the next group of mounting holes 104. At this time, insert the two vertical rods 22 into the corresponding mounting grooves 33, and then move the support plate 36 and the connecting platform 35 in turn, so that the sliding rod 34 is inserted into the connecting hole 221 and a limit is formed between the limit rod 37 and the sliding rod 34.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
