When the limiting plate on the upper surface of the left cleaning roller or the upper surface of the right cleaning roller is perpendicular to the conveying belt, the distance between the limiting plate and the conveying belt at the moment is not more than 10mm.
In the technical scheme, when the particles on the conveying belt need to be cleaned, the exhaust fan is started to suck air into the dust suction port, so that negative pressure air flow is generated in the dust suction port, and the negative pressure air flow drives the limiting plate on the right side of the left cleaning roller and pulls the limiting plate on the left side of the right cleaning roller downwards through the blocking of the inner convex plate, so that the left cleaning roller rotates clockwise and the right cleaning roller rotates anticlockwise.
In the moving process of the conveying belt, when particulate matters with the height higher than 10mm exist under the surface of the conveying belt, the limiting plates form a notch, so that the particulate matters with the height higher than 10mm are contained in the notch, and then the limiting plates rotate to enable the particulate matters with the height higher than 10mm to reach the dust suction opening and be sucked and taken down through the dust suction opening.

When the limiting plate 31 on the upper surface of the left cleaning roller 30 or the upper surface of the right cleaning roller 40 is perpendicular to the conveyor belt 1, the distance between the limiting plate 31 and the conveyor belt 1 at this time is not more than 10mm.
The implementation steps are as follows: when the particles on the conveying belt 1 need to be cleaned, the exhaust fan 20 is started to suck air into the dust suction port 11, so that the dust suction port 11 generates negative pressure air flow, and the negative pressure air flow drives the limiting plate 31 on the right side of the left cleaning roller 30 and the limiting plate 31 on the left side of the right cleaning roller 40 to move downwards through the blocking of the inner convex plate 12, so that the left cleaning roller 30 rotates clockwise and the right cleaning roller 40 rotates anticlockwise.
When the particulate matters with the height higher than 10mm exist under the surface of the conveying belt 1 in the moving process of the conveying belt 1, the limiting plates 31 form a notch therebetween, so that the particulate matters with the height higher than 10mm are accommodated in the notch, and then the limiting plates 31 rotate, so that the particulate matters with the height higher than 10mm reach the dust suction opening 11 and are sucked down through the dust suction opening 11.
