Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The embodiment of the utility model provides a technical solution: a special square bearing sleeve for a roller brush device, comprising a device body 1, the device body 1 comprising a square bearing sleeve 2 and a roller brush driving square shaft 3, the roller brush driving square shaft 3 is installed in the square bearing sleeve 2;

[0021] The problem is that the square bearing sleeve 2 includes an external bearing 4 and a bearing mounting block 5, the external bearing 4 is a ring-shaped structure, and the bearing mounting block 5 is provided with two groups. The external bearing 4 and the two groups of bearing mounting blocks 5 are a smooth transition and integrally processed structure, and the two groups of bearing mounting blocks 5 are located on the outside of the external bearing 4 in a ring-shaped and equidistant manner, and the bearing mounting block 5 is an N-shaped structure. A fixing hole 6 is opened on the surface of the bearing mounting block 5. When in use, the staff fits the square bearing 2 to the installation point, and the staff inserts the bolts into the fixing holes 6 of the bearing mounting block 5, and then the square bearing sleeve 2 can be fixed, and the staff drives the roller brush to penetrate the square shaft 3 into the internal bearing 8 inside the external bearing 4, thereby achieving the installation purpose.

[0022] Furthermore, a group of reinforcing connecting blocks 7 are provided between the bearing mounting blocks 5, the inner end of the reinforcing connecting block 7 is an arc-shaped structure, and is welded to the outer side of the external bearing 4 by welding, and the reinforcing connecting block 7 is a trapezoidal structure. The reinforcing connecting blocks 7 are provided between the bearing mounting blocks 5 to improve the stability and firmness of the overall structure of the square bearing sleeve 2 and prevent a group of bearing mounting blocks 5 from breaking.

[0023] Differently, an internal bearing 8 is installed inside the external bearing 4 , and the internal bearing 8 inside the external bearing 4 is for facilitating the installation of the roller brush driving square shaft 3 and ensuring the stability and smoothness of the rotation of the roller brush driving square shaft 3 .

[0024] Effectively, the external bearing 4, the bearing mounting block 5, the reinforcing connecting block 7 and the internal bearing 8 are all made of alloy steel. The wear resistance and high temperature resistance of the parts can be effectively improved by using the external bearing 4, the bearing mounting block 5, the reinforcing connecting block 7 and the internal bearing 8 made of alloy steel.

[0025] Working principle: During operation, when in use, the staff will fit the square bearing 2 to the installation point, and the staff will use bolts to insert into the fixing holes 6 of the bearing mounting block 5, and then the square bearing sleeve 2 can be fixed.
