So arranged, when the foreign matter such as rope is rolled away by the roller brush 4, and then is laid on the comb teeth 61, thereby cleaning the roller brush 4, so that the roller brush 4 can maintain the cleaning ability. In addition, because the comb teeth 61 have a certain distance, the user can take out the impurities such as the rope from the comb teeth 61 conveniently. It need be deep to understand, based on comb strip 6 static, and roller brush 4 operation, under the effect of inertial force, it rises impurity to tear apart and get rid of to change in the rope on the roller brush 4 to make impurity such as rope easily transfer to comb strip 6 from roller brush 4, not only do not need the user to accomplish cleaning on roller brush 4, moreover, from the clear degree of difficulty of comb strip 6 on be less than from the clear degree of difficulty of roller brush 4, greatly reduced the clean degree of difficulty promptly.

It should be noted that, in the original arrangement scheme, the roller brush 4 is driven by manual rotation (of course, the brush bristles 41 of the roller brush 4 abut against the wall of the mesh-shaped filtering roller 2, so the mesh-shaped filtering roller 2 drives the roller brush 4 to rotate), which also meets the use condition of the actual product. In a further development, the second rotary drive 5 is added.

In order to prevent the comb teeth 6 from being broken, it is preferable that the comb teeth 6 be made of a metal material.

In order to facilitate the cleaning of the comb teeth bars 6 by the user, it is preferable that the cylinder brush 4 and the comb teeth bars 6 are provided outside the mesh-shaped filter cylinder 2.

Preferably, the sand sieving device with cleaning function further comprises an inclined upward feeding conveyor 8, the inclined upward feeding conveyor 8 being located directly below the mesh-like filtering drum 2 and serving to convey sand upward to the blanking station. In operation, sand enters the mesh-shaped filter drum 2 through the hopper 7, falls onto the inclined upward feeding conveyor 8, and is sent out of the frame 1.

Preferably, in order to drive the mesh-shaped filter drum 2 more smoothly, the sand screening device with the cleaning function further comprises a reinforcing support 9 arranged inside the mesh-shaped filter drum 2, the reinforcing support 9 comprises an annular frame 91 and a plurality of reinforcing rods 92, the annular frame 91 is fixedly connected with the inner wall of the mesh-shaped filter drum 2, the reinforcing rods 92 are positioned in the annular frame 91, two ends of each reinforcing rod 92 are respectively fixedly connected with the annular frame 91, each reinforcing rod 92 passes through the center of the annular frame 91 to form a driving part, and the first rotary driving mechanism 3 is in driving connection with the driving part.

Preferably, the first rotary drive mechanism 3 and the second rotary drive mechanism 5 are both motors.
