When grinding the surface of the cement concrete slab, the vacuum fan is turned on, and the suction force generated by the vacuum fan is used to suck the waste chips and dust generated during grinding into the collection box through the mesh plate. At the same time, the square frame is separated from the mesh plate and moves downward through the sliding shaft by the suction force of the vacuum fan, so that the impurities and waste chips generated during grinding fall on the baffle plate for collection.

[0005] The beneficial effects of the present invention are as follows: 1. The present invention provides a grinding component. When the cement concrete slab is transported and moved by the conveying component, the small motor is turned on and the output end of the small motor drives the screw rod to rotate in the fixed frame, thereby driving the movable plate to perform corresponding adjustment work according to the position of the cement concrete slab. At the same time, the surface of the cement concrete slab is ground by the grinding block and the friction mechanism. When the cement concrete slab is ground, an instruction is issued by controlling the control panel, so that the jet mechanism blows air to the surface of the cement concrete slab, thereby blowing off the waste chips generated during the grinding to both sides of the cement concrete slab, so as to facilitate the subsequent collection component to collect the waste chips.

[0006] 2. The present invention sets a friction mechanism. When the grinding block grinds the surface of the cement concrete slab, the output end of the motor is controlled to drive the hydraulic rod to move downward, so that the cleaning block drives the steel brush to clean the surface of the cement concrete slab, and the waste generated when the cement concrete slab is grinded is swept away.

[0007] 3. The present invention provides an ejection mechanism. When the grinding work is completed and the air suction machine stops working, the square frame drives the ejection rod to move upward through the tensile force of the third spring, thereby driving the ejection pin to eject the impurities stuck in the mesh holes of the mesh plate through the ejection rod, thereby preventing the impurities generated during processing from entering the collection box through the mesh plate, and the impurities and gravel will be stuck in the mesh holes of the mesh plate, causing the mesh plate to be blocked. When the extrusion force between the ejection pin and the gravel stuck between the mesh holes is greater than the tensile force of the fourth spring, the ejection pin drives the slider to slide in the notch through the round rod, thereby preventing the extrusion force between the ejection pin and the impurities stuck between the mesh holes from being too large, and then when the ejection pin ejects the impurities, extrusion damage will be caused to the side of the ejection pin. At the same time, when the ejection pin moves in the mesh hole, it also drives the arc plate to clean the inner side of the mesh hole, thereby preventing the dust generated during processing from adhering to the inner side of the mesh hole.

[0008] 4. The present invention provides a contact mechanism. When the suction machine is working, the suction force generated by the suction machine causes the contact rod to rotate on the baffle through the rotating shaft, so that the gravel impurities adsorbed on the baffle are swept to the surroundings of the baffle, thereby avoiding a large amount of gravel to accumulate in the ventilation area of ​​the baffle. At the same time, a brush is provided on the side of the contact rod. When the contact rod rotates on the baffle, the brush can clean the top of the baffle. When the contact rod rotates, it drives the grabbing rod to rotate in the rotating groove. By opening arc grooves on both sides of the grabbing rod, when the grabbing rod rotates, the flocculent dust from the outside that follows the grinding debris and is sucked into the collection box can be grabbed, thereby avoiding a large amount of flocculent dust from being entangled on the rotating shaft, thereby interfering with the normal rotation of the rotating shaft.

At the same time, when the steel brush 687 and the surface of the cement concrete slab are pressed against each other for cleaning, the rubber rod 6811 is first used to squeeze the surface of the cement concrete slab, so that the rubber rod 6811 drives the circular plate 686 to move on the steel brush 687, and at the same time, the circular plate 686 drives the cleaning component 689 to clean the side of the steel brush 687. When the grinding work on the surface of the cement concrete slab is completed, when the rubber rod 6811 and the cement concrete slab are released from the extrusion limit, the circular plate 686 is driven by the reset of the first spring 6810, so that the scraper 6893 and the side of the steel brush 687 are moved for cleaning. At the same time, when the scraper 6893 and the steel brush 687 are in contact for cleaning, the scraper 6893 can be buffered by the tensile force of the second spring 6894, so as to avoid excessive extrusion pressure of impurities between the steel brush 687 and the scraper 6893, which will cause damage to the steel brush 687, thereby avoiding a large amount of waste debris adhering to the steel brush 687 when the steel brush 687 is cleaning the surface of the cement concrete slab, which is difficult to fall off naturally; When grinding the surface of the cement concrete slab, the vacuum fan 83 is turned on, and the suction force generated by the vacuum fan 83 is used to suck the waste and dust generated during grinding into the collection box 81 through the mesh plate 82. At the same time, the square frame 87 is separated from the mesh plate 82 and moves downward through the sliding shaft 86 by the suction force of the vacuum fan 83, so that the impurities and waste generated during grinding fall on the baffle 84 for collection. At the same time, the contact mechanism 85 is rotated on the baffle 84 by the suction force generated by the vacuum fan 83, so as to prevent a large amount of processing waste and gravel falling from the cement concrete slab from accumulating in the ventilation area of ​​the baffle 84. When the grinding work is completed and the suction machine 83 stops working, the square frame 87 drives the ejector rod 891 to move upward through the tensile force of the third spring 88, so that the ejector rod 891 drives the ejector pin 895 to eject the impurities stuck in the mesh of the mesh plate 82, thereby preventing the impurities generated during processing from entering the collection box 81 through the mesh plate 82, and the impurities and gravel will be stuck in the mesh of the mesh plate 82, causing the mesh plate 82 to be blocked. When the tensile force of the fourth spring 897 is greater than the tensile force of the fourth spring 897, the ejector pin 895 drives the slider to slide in the slot 892 through the round rod 894, thereby preventing the ejector pin 895 from squeezing the impurities stuck between the meshes too much, and then when the ejector pin 895 ejects the impurities, squeezing damage will be caused to the side of the ejector pin 895. At the same time, when the ejector pin 895 moves in the mesh, it drives the arc plate 896 to clean the inside of the mesh, thereby preventing the dust generated during processing from adhering to the inside of the mesh. When the suction machine 83 is working, the suction force generated by the suction machine 83 causes the contact rod 851 to rotate on the baffle 84 through the rotating shaft 852, so that the gravel impurities adsorbed on the baffle 84 are swept to the surroundings of the baffle 84, thereby avoiding a large amount of gravel to accumulate in the ventilation area of ​​the baffle 84. At the same time, a brush 853 is provided on the side of the contact rod 851. When the contact rod 851 rotates on the baffle 84, the brush 853 can clean the top of the baffle 84. When the contact rod 851 rotates, it drives the grabbing rod 855 to rotate in the rotating groove 854. By providing arc grooves 856 on both sides of the grabbing rod 855, when the grabbing rod 855 rotates, the flocculent dust from the outside that is sucked into the collecting box 81 along with the grinding debris can be grabbed, thereby avoiding a large amount of flocculent dust from being entangled on the rotating shaft 852, thereby interfering with the normal rotation of the rotating shaft 852.
