Detailed Description of the Embodiment

[0030] The following will Figure 1 - with reference to the attached Figure 3 drawings to further describe the present application in detail.

[0031] The embodiment of the present application discloses a large material grinding device. Referring to Figure 1 , it includes a conveyor belt 1 erected on the ground. There is a support frame 3 above the conveyor belt 1. The support frame 3 is in a portal shape and both ends of the support frame 3 are abutted against the ground. Referring to Figure 1 and Figure 2 , a moving plate 4 is provided on the support frame 3, and a counterweight 11 is fixedly connected to the upper end of the moving plate 4. A driving assembly 5 for driving the moving plate 4 to move on the support frame 3 is provided on the support frame 3.

[0032] The driving assembly 5 includes multiple pairs of pulleys 51 rotatably connected to the lower end of the moving plate 4. In this embodiment, two pairs of pulleys 51 are provided. A same second driving motor 52 is provided between the pulleys 51 of the same pair. The output shaft of the second driving motor 52 is coaxially arranged and fixedly connected with the pulley 51, and the second driving motor 52 is fixedly connected to the lower end of the moving plate 4.

[0033] Thus, the second driving motor 52 is started, so that the second driving motor 52 drives the pulley 51 to slide on the support frame 3, and further the moving plate 4 moves on the support frame 3. At the same time, in order to improve the sliding stability of the pulley 51 on the support frame 3, a limiting groove 31 is formed on the upper end surface of the support frame 3 corresponding to the pulley 51. The limiting groove 31 is arranged along the upper length direction of the support frame 3, and the pulley 51 is slidably connected in the chute.

[0034] A lifting plate 6 is arranged below the moving plate 4. The lifting plate 6 is in a cuboid shape, and a lifting assembly 8 for driving the lifting plate 6 to lift is arranged between the moving plate 4 and the lifting plate 6.

[0035] The lifting assembly 8 includes two hydraulic cylinders 81. The telescopic direction of the hydraulic cylinder 81 is perpendicular to the lower end surface of the moving plate 4. The bottom end of the hydraulic cylinder 81 is fixedly connected to the lower end of the moving plate 4, and the telescopic end of the hydraulic cylinder 81 is fixedly connected to the upper end of the lifting plate 6.

[0036] Thus, by controlling the telescopic movement of the hydraulic cylinder 81, the hydraulic cylinder 81 can drive the lifting plate 6 to move up and down.

[0037] A mounting plate 9 is arranged below the lifting plate 6. A first driving motor 41 for driving the mounting plate 9 to rotate is arranged between the lifting plate 6 and the mounting plate 9. The bottom end of the first driving motor 41 is fixedly connected to the lower end of the lifting plate 6, the output shaft of the first driving motor 41 is fixedly connected to the upper end of the mounting plate 9, and the output shaft of the first driving motor 41 is fixedly connected to the upper end of the mounting plate 9.

[0038] Refer to Figure 2 and Figure 3 , a plurality of brush blocks 7 are arranged at the lower end of the mounting plate 9, and a plurality of bristles 71 are fixedly connected to the lower end of the brush block 7. A connecting member 91 for connecting the two is arranged between the brush block 7 and the mounting plate 9. In this embodiment, the connecting member 91 is arranged as a locking bolt, and two connecting bolts are arranged on each brush block 7. The locking bolt is threadedly connected to the mounting plate 9, and the rod portion of the locking bolt passes through the mounting plate 9 and is threadedly connected to the brush block 7.

[0039] Thus, by rotating the locking bolt, the locking bolt can be disengaged from the brush block 7, and thus the disassembly of the brush block 7 on the mounting plate 9 can be realized.

[0040] Refer to Figure 1 and Figure 2, a placing plate 2 for placing workpieces is fixedly connected to the conveyor belt 1. A collection box 10 is provided on one side of the conveyor belt 1. The collection box 10 is arranged in a cuboid shape and the upper end of the collection box 10 is open. The collection box 10 is arranged along the length direction of the conveyor belt 1 of the moving conveyor belt 1.

[0041] The placing plate 2 includes a fixed part 21 and a rotating part 22. The fixed part 21 and the rotating part 22 are stacked. One end of the rotating part 22 is rotatably connected to one end of the fixed part 21 close to the collection box 10. A driving member 23 for driving the rotating part 22 to rotate is provided on the fixed part 21.

[0042] The driving member 23 is arranged as a rotating motor. The rotating motor is fixedly connected to the fixed part 21, and the output shaft of the rotating motor is fixedly connected to the rotating part 22.

[0043] Thus, start the driving motor to drive the rotating part 22 in the placing plate 2 to rotate towards the collection box 10, so that the zinc blocks accumulated on the rotating part 22 fall into the collection box 10.

[0044] The implementation principle of an abrasive device for large materials in an embodiment of the present application is as follows: The tool to be cleaned can be placed on the placing plate 2 on the conveyor belt 1. Subsequently, the conveyor belt 1 can be started to place the workpiece under the support frame 3. Then, control the hydraulic cylinder 81 to drive the hydraulic cylinder 81 to descend, so that the bristles 71 of the brush block 7 on the mounting plate 9 are in contact with the workpiece. Subsequently, start the first driving motor 41 to rotate the bristles 71, and repeatedly clean the surface of the workpiece during the rotation. At the same time, drive the pulley 51 to move repeatedly on the support frame 3 through the second driving motor 52, so that the moving plate 4 moves repeatedly, and the bristles 71 repeatedly sweep the workpiece. The zinc blocks falling on the upper end of the rotating part 22 during the sweeping process can drive the workpiece. After the cleaning is completed, start the rotating motor to rotate the rotating part 22, so that the zinc blocks accumulated on the rotating part 22 fall into the collection box 10.

[0045] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this.
