[0025] In order to enable those skilled in the art of this technology to better understand the solution of this application, the following further detailed description of this application will be made in conjunction with the drawings and specific implementation modes.

[0026] Embodiment:

[0027] Referring to the attached Figures 1 - 4 , a brush shaft for a belt conveyor in this embodiment includes a cleaning brush barrel 1 and coupling shafts 2 provided on both sides of the cleaning brush barrel 1. First connecting grooves 3 are respectively and penetratingly opened at both ends of the cleaning brush barrel 1. A backing plate 4 is fixedly installed at the inner end of the coupling shaft 2. And the diameter of the cleaning brush barrel 1 is equal to the diameter value of the backing plate 4. A first connecting bump 5 adapted to the first connecting groove 3 is integrally provided at the inner end of the backing plate 4. Through the first connecting groove 3 and the first connecting bump 5, a tight fit between the cleaning brush barrel 1 and the coupling shafts 2 on both sides is achieved, reducing relative movement, improving stability, and avoiding poor cleaning effect or equipment damage caused by shaking.

[0028] Referring to the attached Figure 4 and Figure 5 , an annular washer 6 is fixedly installed at the bottom of the backing plate 4. A fixed washer 7 is arranged above the annular washer 6. The thicknesses of both the annular washer 6 and the fixed washer 7 are greater than the thickness of the backing plate 4. The annular washer 6 and the fixed washer 7 have the same specifications and are both semi-annular structures. And the diameter of the cleaning brush barrel 1 is equal to the inner diameter values of the annular washer 6 and the fixed washer 7. The designs of the annular washer 6 and the fixed washer 7 provide stable support for the cleaning brush barrel 1.

[0029] During installation, place the cleaning brush barrel 1 on the annular washer 6. The annular washer 6 receives the cleaning brush barrel 1, and then cover the fixing washer 7. A plurality of connecting pieces 10 are arranged between the annular washer 6 and the fixing washer 7 on the same side. The connecting piece 10 is used to connect the annular washer 6 and the fixing washer 7 on the same side. The combined use of the annular washer 6 and the fixing washer 7 not only facilitates installation and disassembly, but also ensures the firmness of the connection and extends the service life of the equipment.

[0030] Refer to the appendix Figure 6 , the connecting piece 10 includes a plug rod 1001. A limiting block 1002 is arranged at the top of the plug rod 1001. An installation groove 1003 is opened on the plug rod 1001. A spring 1004 is arranged in the installation groove 1003. A clamping block 1005 is fixedly installed at the outer end of the spring 1004. Upper connection holes are opened on both sides of the fixing washer 7, and lower connection holes are opened on both sides of the annular washer 6. When connecting, insert the plug rod 1001 into the upper connection hole and the lower connection hole. When inserting, first press the clamping block 1005 to make it retract into the installation groove 1003. At this time, the spring 1004 is in a compressed state. During the insertion process, the inner walls of the upper connection hole and the lower connection hole obstruct the clamping block 1005, making the clamping block 1005 unable to pop out. When the bottom of the limiting block 1002 fits with the upper surface of the fixing washer 7, at this time the lower connection hole no longer obstructs the clamping block 1005, that is, the clamping block 1005 pops out to realize the limitation of the plug rod 1001, that is, the connection between the fixing washer 7, the annular washer 6 and the connecting piece 10 is realized. This design simplifies the installation steps and improves the installation efficiency.

[0031] Refer to the appendix Figure 4 and Figure 5 , a second connection groove 8 is penetrated and opened at the top of the backing plate 4. The first connection groove 3 and the second connection groove 8 are vertically arranged. A second connection convex block 9 adapted to the second connection groove 8 is integrally arranged on the inner side of the top of the fixing washer 7. The arrangement of the second connection groove 8 and the second connection convex block 9 enhances the connection between the fixing washer 7 and the backing plate 4, further improves the stability and reliability of the entire brush shaft, and ensures the durability of the cleaning effect during the operation of the belt conveyor.

[0032] Both sides of the coupling shaft 2 are made of stainless steel material, which can improve the wear resistance of the coupling shaft 2 and extend the service life of the coupling shaft 2. The plug rod 1001 and the clamping block 1005 are both made of carbon steel material to ensure that they can withstand sufficient tensile force and shear force.

[0033] In the present utility model, the cleaning brush barrel 1 is closely attached to the backing plate 4 on the connecting shaft 2 through the first connecting groove 3. The annular washer 6 and the fixed washer 7 are fixed by the connecting member 10 to ensure the stable support of the cleaning brush barrel 1. The second connecting bump 9 on the fixed washer 7 further enhances the connection with the backing plate 4, improving the overall stability and service life.

[0034] Finally, the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
