[0032] Compared with the prior art, the curbstone 12 polishing equipment provided by the utility model has the following beneficial effects: the belt conveyor mechanism 6 is an inclined structure, and the waste water generated during milling and polishing can easily flow downward from the inclined conveyor belt 61, without forming siltation or a small amount of silt remaining on the equipment, thereby reducing the amount of water and time used for flushing the silt, facilitating silt cleaning, and reducing the time for cleaning the grinding silt.

[0033] In some embodiments, Figure 6 As shown, it also includes a rear guard beam adjustment mechanism 9, which includes a support beam 11, a screw rod 901 and a nut 902. The number of support beams 11 is the same as the number of inclined beams. The support beam 11 is located above the belt conveyor mechanism 6 and is parallel to the inclined beam. The front and rear ends of the support beam 11 are respectively connected to the inclined beam through short columns, and the belt conveyor mechanism 6 is located between the two short columns; the front and rear ends of the screw rod 901 are rotatably connected to the support beam 11, the nut 902 is threadedly connected to the screw rod 901, and the rear guard beam 10 is connected to the nut 902. The rear guard beam adjustment mechanism 9 can be driven by a reduction motor to drive the screw rod 901 or manually driven by a hand wheel 908 to control the movement of the rear guard beam 10, so as to facilitate the front and rear adjustment of the position of the rear guard beam 10 when changing products with different widths.

[0034] In some embodiments, Figure 6As shown, the support beam 11 is a square tube, the screw rod 901 is inserted into the square tube, and end caps are provided at both ends of the square tube. The screw rod 901 is rotatably connected to the end caps at both ends. Optionally, the support beam 11 is a round tube.
