Debris dropped from the rotating mesh plate 11 can enter the debris collection box 3 along the material guide trough 2 to collect the debris.

[0026] Cutting pads 12 are fixed to the top and bottom of the rotating screen plate 11. During the processing of PC bricks, PC brick raw materials are placed on the cutting pads 12, and a cutting seam is provided between two adjacent cutting pads 12 to facilitate the cutting of the PC brick raw materials.

[0027] Both ends of the top of the cutting table 1 are fixedly connected with a hydraulic telescopic rod 4, and the top of the hydraulic telescopic rod 4 is fixedly connected with a sealing cover 5. Through the setting of the hydraulic telescopic rod 4, the extension and retraction of the hydraulic telescopic rod 4 can change the position of the sealing cover 5 fixedly connected thereto. When the cross-cutting machine cuts the PC brick raw material, the bottom of the sealing cover 5 contacts the top of the cutting table 1, and the rotating mesh plate 11 is located in the inner cavity of the sealing cover 5. At this time, the sealing cover 5 can intercept the debris and dust generated during the cutting process, so that the debris can fall on the rotating mesh plate 11, which is convenient for collecting and cleaning the debris and dust.

The debris falling on the pressing plate 13 is blown onto the rotating mesh plate 11 by the dust blowing plate 20. The debris smaller than the mesh diameter of the rotating mesh plate 11 falls directly into the debris collection box 3 under the action of gravity, and the remaining debris falls into the debris collection box 3 when the rotating mesh plate 11 is flipped, thereby realizing the operation of cutting and cleaning at the same time, and can ensure the efficiency and effect of debris cleaning.
