[0021] Refer to the instruction manual Figure 3 , Instruction Manual Figure 4 , Instruction Manual Figure 5 , Instruction Manual Figure 6 And the instruction manual Figure 7 The revolution part 14 includes a fixed circular groove 19 arranged on the inner wall of the collecting frame 9, a rotating ring 20 is rotatably connected in the fixed circular groove 19, arc grooves 21 are arranged on the upper and lower surfaces of the rotating ring 20, and a plurality of rotating balls 22 are arranged at the upper and lower ends of the fixed circular groove 19, the rotating balls 22 are in contact with the arc grooves 21, fixed bearings 23 are installed on both sides of the inner wall of the rotating ring 20, a rotating rod 24 is arranged between the two fixed bearings 23, the outer ring of the fixed bearing 23 is fixedly connected to the inner wall of the rotating ring 20, the inner ring of the fixed bearing 23 is fixedly connected to the rotating rod 24, a wire brush 25 is installed on the rotating rod 24, a gear ring 26 is installed on the outer ring of the rotating ring 20, a fixed through groove 27 is provided on one side of the collecting frame 9, the fixed through groove 27 is communicated with the fixed circular groove 19, the driving gear 13 is located in the fixed through groove 27 and meshes with the gear ring 26.

[0022] Specifically in practical applications, the collecting frame 9 rises to make the wire brush 25 contact with the bottom surface of the tamping hammer 3, and the driving motor 12 starts to work. The output end of the driving motor 12 drives the driving gear 13 to rotate, and the driving gear 13 and the gear ring 26 are meshed with each other. The driving gear 13 drives the gear ring 26 to drive the rotating ring 20 to rotate, and the rotating ring 20 rotates along the rotating ball 22 through the arc groove 21.

[0023] Refer to the instruction manual Figure 4 , Instruction Manual Figure 5 And the instruction manual Figure 7 The self-rotating cleaning part 15 includes a bevel gear ring 28 installed on the inner wall of the collecting frame 9, the bevel gear ring 28 is located above the rotating rod 24, a bevel gear 29 is installed at one end of the rotating rod 24, the bevel gear 29 and the bevel gear ring 28 are meshed with each other, a fixed support plate 30 is installed in the collecting frame 9, the fixed support plate 30 is located below the rotating rod 24, and a plurality of cleaning rods 31 are installed on the surface of the fixed support plate 30.

[0024] Specifically in actual application, when the rotating ring 20 drives the rotating rod 24 to revolve, the bevel gear 29 on the rotating rod 24 meshes with the bevel gear ring 28, and the bevel gear 29 will rotate along the bevel gear ring 28. The bevel gear 29 drives the rotating rod 24 to rotate between the two fixed bearings 23, and the rotating rod 24 drives the wire brush 25 to rotate. Under the action of the rotational force, the coal on the bottom surface of the tamping hammer 3 can be completely cleaned off, thereby improving the cleaning effect. When the wire brush 25 contacts the cleaning rod 31, the coal stuck on the wire brush 25 can be cleaned off through the cleaning rod 31, thereby avoiding affecting the cleaning effect of the tamping hammer 3.

[0025] Refer to the instruction manual Figure 3 And the instruction manual Figure 4 The collecting frame 9 is provided with an annular elastic cloth 32, which is located above the bevel gear ring 28, and the outer ring of the annular elastic cloth 32 is fixedly connected to the inner wall of the collecting frame 9, and the inner diameter of the annular elastic cloth 32 is smaller than the diameter of the tamping hammer 3.

[0026] Specifically in practical applications, when the collecting frame 9 rises, the annular elastic cloth 32 is put on the tamping hammer 3, and the inner circle of the annular elastic cloth 32 is tightly fitted with the tamping hammer 3. When cleaning the attachments on the bottom surface of the tamping hammer 3, the coal ash is prevented from floating out to pollute the air, thereby avoiding pollution to the working environment and keeping the working environment clean.

[0027] Refer to the instruction manual Figure 8 There is a gap between the top of the cleaning rod 31 and the rotating rod 24 , the fixed support plate 30 is trapezoidal, and the upper bottom width of the fixed support plate 30 is the same as the diameter of the cleaning rod 31 .

[0028] Specifically in practical applications, the fixed support plate 30 is trapezoidal, narrow at the top and wide at the bottom, so that the coal falling on the fixed support plate 30 can slide down, thereby preventing the coal from remaining on the fixed support plate 30 .

[0029] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 And the instruction manual Figure 4 The bottom end of the collecting frame 9 is connected with a discharge pipe 33 , which extends through the fixed bottom plate 8 , and a flap valve 34 is provided on the discharge pipe 33 .

[0030] Specifically in practical applications, the coal cleaned from the bottom surface of the tamping hammer 3 is collected in the collecting frame 9. When the coal-loading car is tamped next time, the flap valve 34 is opened, and the coal in the collecting frame 9 falls into the coal-loading car through the discharge pipe 33. The hydraulic cylinder 6 and the linear slide 5 work again to move the collecting frame 9 away from under the tamping hammer 3.

[0031] Refer to the instruction manual Figure 3 And the instruction manual Figure 4 The inner diameter of the collecting frame 9 is larger than the diameter of the tamping hammer 3 , and the inner diameter of the bevel gear 29 is larger than the diameter of the tamping hammer 3 .

[0032] Specifically in practical applications, the bottom surface of the tamping hammer 3 passes through the bevel gear 29 and the tamping hammer 3, so that the attached coal can be completely cleaned and collected.
