[0024] Further, the lower end of first connecting table 2 is fixedly connected with the first second connecting table 26 on the upper surface close to connecting ring 9, and the first second connecting table 26 is connected with the brush plate 27 on the upper surface, and the brush plate 27 is fixedly connected with the brush head 28 on the upper surface.

[0025] Further, support wheel 7 is fixedly connected to the outer surface of connecting shaft 5 through the threaded connection of screw rod 6 and nut 8, support wheel 7 is fixedly connected to the outer surface of connecting shaft 5 through the threaded connection of screw rod 6 and nut 8, sliding slot 11 is a "T" shaped groove, sliding block 12 is a "convex" shaped block, sliding block 12 is fixedly connected with limit frame one 13, limit frame one 13 and limit frame two 24 are both "mouth" shaped plates, limit frame one 13 is slidably connected to the upper surface of first connecting table 2, limit frame two 24 is fixedly connected to the upper surface of first connecting table 2, which can limit support wheel 7 and connecting sleeve 71 by limit frame one 13 and limit frame two 24, so that support wheel 7 and connecting sleeve 71 rotate between limit frame one 13 and limit frame two 24, limit frame one 13 slides on the upper surface of first connecting table 2, so that the position of limit frame one 13 on first connecting table 2 is adjusted, thereby facilitating the disassembly of support wheel 7 and connecting sleeve 71.

[0026] Further, the fixed plate 14 is in the shape of an "L" plate, the lead screw 16 is in the shape of a rod, and the lead screw 16 is rotatably connected below the fixed plate 14.

The limiting column 22 limits the rotation of the supporting wheel 7, so that the supporting wheel 7 can be disassembled by sliding the limiting frame one 13 on the upper surface of the first connecting table 2, so that the moving block one 21 slides in the inside of the connecting groove one 20. When the moving block one 21 slides to the innermost end of the connecting groove one 20, the limiting column 22 moves synchronously with the limiting frame one 13 as the moving block two 23 continues to slide, so that the moving block two 23 slides in the inside of the connecting groove two 25, thereby adjusting the position of the limiting column 22 and making the limiting column 22 away from the connecting sleeve 71.

[0029] Further, the first and second connecting tables 26 are in the shape of an arc block, the brush plate 27 is in the shape of an arc plate, and the brush head 28 is in the shape of a plurality of fixed connections on the outer surface of the brush plate 27.

[0031] The first second connecting table 26 is fixedly connected to the upper surface of the first connecting table 2 near the lower end of the connecting ring 9, the upper surface of the first second connecting table 26 is connected with a brush plate 27, the upper surface of the brush plate 27 is fixedly connected with a brush head 28, by starting the motor 4, the output shaft of the motor 4 drives the machine box components in the gearbox 3 to rotate, thereby driving the connecting shaft 5 to rotate, thereby driving the supporting wheel 7 and the connecting sleeve 71 to rotate, thereby driving the connecting ring 9 and the drum screen body 10 to rotate, since the brush head 28 is in contact with the outer surface of the connecting ring 9, the rotation of the connecting ring 9 causes the brush head 28 to scrape the outer surface of the connecting ring 9, thereby preventing the connecting ring 9 from containing a large amount of the connecting sleeve 71 due to the friction between the connecting sleeve 71 and the connecting ring 9, thereby affecting the subsequent rotation effect of the connecting ring 9.

[0032] It is apparent for a person skilled in the art that the present application is not limited to the details of the above exemplary embodiments but can be implemented in other embodiments without departing from the scope of the present application. The embodiments are therefore to be seen as exemplary and not restrictive and the scope of the application is defined by the appended claims and not by the above description, and all changes coming within the meaning and range of equivalents of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
