[0024] The anti-skid assembly comprises a plurality of anti-skid grooves 201 formed in the side walls of the rollers 103, each anti-skid groove 201 is arranged in an annular array, and the side of the conveying belt 104 close to the roller 103 is provided with a plurality of anti-skid plates 202 at equal intervals, each anti-skid plate 202 is arranged in matching with the anti-skid groove 201, and the roller 103 is provided with a cleaning assembly for cleaning the anti-skid groove 201;

[0025] It should be noted that: through the arrangement of the anti-skid assembly, the contact area and friction force between the roller 103 and the conveying belt 104 are significantly increased, a plurality of small “engaging points” are formed, thereby increasing the driving force of the roller 103 on the conveying belt 104, reducing the risk of slipping of the conveying belt 104 on the roller 103 when conveying heavy materials or encountering sudden resistance, and further ensuring stable transmission of power and reducing the risk of jamming caused by slipping.

[0026] Please refer to Figures 1-6The cleaning assembly in the figure comprises cleaning plates 301 slidably connected to the anti-skid grooves 201, each cleaning plate 301 is arranged in matching with the anti-skid groove 201, and each cleaning plate 301 is fixedly connected with L-shaped plates 302 at opposite ends, the drum 103 is provided with sliding holes 303 opposite to the two side walls, the opposite two L-shaped plates 302 are slidably connected to the sliding holes 303, and each sliding hole 303 is provided with an extension assembly for extending and retracting the L-shaped plate 302, and the opposite two support frames 101 are provided with a driving assembly for driving the cleaning plate 301 and a collecting assembly for collecting impurities cleaned by the cleaning plate 301;

[0027] It should be noted that, through the arrangement of the cleaning assembly, the impurities falling into the anti-skid groove 201 are cleaned, and are collected under the collection of the collecting assembly, thereby reducing the risk that the drum 103 is unstable in driving the conveying belt 104 due to the impurities falling into the anti-skid groove 201.

[0028] Please refer to Figures 3-5 , each sliding hole 303 in the figure is provided with an extension sealing sleeve 304;

[0029] It should be noted that, through the arrangement of the extension sealing sleeve 304, the sliding of the L-shaped plate 302 in the sliding hole 303 is not affected while providing a sealing effect for the sliding hole 303.

[0030] Please refer to Figure 5 and Figure 6 , the extension assembly in the figure comprises two fixed rods 401 fixedly connected between the opposite two inner walls of the sliding hole 303, the L-shaped plate 302 is slidably connected to the fixed rod 401, the two fixed rods 401 are provided with springs 402 on the side walls, and the two ends of the two springs 402 are connected with the L-shaped plate 302 and the inner wall of the sliding hole 303 respectively;

[0031] It should be noted that, through the arrangement of the extension assembly, a guiding and resetting effect is provided for the movement of each cleaning plate 301.

[0032] Please refer to Figure 3 and Figure 4 , the driving assembly in the figure comprises a fixed ring 501 fixedly connected to the support frame 101 close to the drum 103, the fixed ring 501 is sleeved on the side wall of the rotating shaft 102, and the fixed ring 501 is fixedly connected with an arc-shaped driving plate 502 away from the contact position of the drum 103 and the conveying belt 104;

[0033] It should be noted that, through the arrangement of the driving assembly, each cleaning plate 301 away from the contact position of the drum 103 and the conveying belt 104 is moved.

[0034] Working principle: when the belt conveyor is in use, the external motor drives the rotating shaft 102 to rotate, and then drives the drum 103 to rotate. In the process of rotating the drum 103, the friction between the drum 103 and the conveyor belt 104 makes the conveyor belt 104 run continuously. When the material is placed on the conveyor belt 104, it will be transported to the designated location along with the movement of the conveyor belt 104;

[0035] And in the process of rotating the drum 103 to drive the conveyor belt 104, the meshing effect of each anti-skid plate 202 and anti-skid groove 201 significantly increases the contact area and friction between the drum 103 and the conveyor belt 104, forming multiple tiny "engaging points", thereby increasing the driving force of the drum 103 on the conveyor belt 104, thereby reducing the risk of slipping of the conveyor belt 104 on the drum 103 when conveying heavy materials or encountering sudden resistance, thereby ensuring stable power transmission and reducing the risk of jamming caused by slipping;

[0036] And in the process of rotating the drum 103, each L-shaped plate 302 will rotate. In the process of rotating each L-shaped plate 302, when each L-shaped plate 302 rotates away from the contact between the drum 103 and the conveyor belt 104, it will abut against the arc-shaped driving plate 502, thereby sliding the cleaning plate 301 in the anti-skid groove 201 under the guidance of the interaction force and the extension assembly, thereby cleaning the impurities falling into the anti-skid groove 201, and collecting them under the collection of the collection assembly, thereby reducing the risk of unstable transmission of the drum 103 to the conveyor belt 104 caused by impurities falling into the anti-skid groove 201, and when each L-shaped plate 302 is away from the arc-shaped driving plate 502, it will shrink into the anti-skid groove 201 under the elasticity of the extension assembly, thereby avoiding interference with the transmission of the conveyor belt 104.

[0037] Embodiment 2

[0038] Please refer to Figure 1 This embodiment further illustrates embodiment 1. The collection assembly in the figure includes L-shaped connecting plates 601 fixedly connected to one side of the opposite two support frames 101. The opposite ends of the two L-shaped connecting plates 601 are provided with dust collectors 602 (as prior art, not described in detail here). The cleaning end of the dust collector 602 is arranged close to the drum 103, and is fixedly connected with an arc-shaped collection cover 603.

[0039] It should be noted that: through the setting of the collection assembly, the impurities cleaned from the anti-skid groove 201 are collected under the adsorption of the dust collector 602 and the guidance of the arc-shaped collection cover 603, thereby facilitating subsequent centralized processing and reducing the risk of impurities falling onto the conveyor belt 104 again.

[0040] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency 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.
