detailed description

The specific embodiment of the utility model will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, a double-crank stone roller grinding device described in the utility model includes a grinding plate 1, a stone roller 4, a gantry frame, a double crank mechanism, an electric motor 8 and a reducer 9; the gantry is erected on the grinding plate 1, a motor 8 and a reducer 9 are fixed in the middle; the stone roller 4 is placed on the grinding plate 1, one end of the stone roller 4 is rotatably connected to the grinding plate 1 through the central vertical shaft 2, and the other end is connected to the reducer 9 through a double crank mechanism. Output shaft; driven by the motor 8, the output shaft of the reducer 9 drives the stone roller 4 to rotate around the central vertical shaft 2 through the double crank mechanism, and the stone roller 4 rolls in a circle on the grinding plate 1 at the same time.

As shown in Figure 2, the outer side of the stone roller 4 is fitted with a support frame 3, horizontal support plates are respectively arranged on the support frames 3 on both sides of the stone roller 4 in the axial direction, and tapered concave holes 41 and horizontal support plates are respectively arranged at both ends of the stone roller 4. The conical top 32 on the inner side of the plate is matched and connected; the horizontal support plate located on the inner side of the stone roller is provided with a through hole 33 for the central vertical shaft 2 to pass through, and the horizontal support plate located on the outer side of the stone roller is provided with a through hole 31 for the shift fork 6 to pass through; The bottom of the central vertical shaft 2 is inscribed in the central groove of the grinding pan 1 .
