[0029] Embodiment 2: Embodiment 2 includes all structures and methods of Embodiment 1, with reference to Figure 1-Figure 7 , a stone grinding machine for convenient discharging, based on Example 1, a gap is left between the connecting disk 12 and the outer wall of the top of the workbench 1, a rotating block 15 is installed at the middle position of the bottom of the connecting disk 12, and a rotating shaft is installed on both sides of the rotating block 15, and a fixed plate 14 is installed at the position corresponding to the rotating shaft on the top of the workbench 1, and the rotating shaft and the fixed plate 14 are rotatably connected, and a motor 2 16 is fixed on the top of the workbench 1, and the output shaft of the motor 2 16 is transmission-connected with the rotating shaft, and the connecting disk 12 and the table panel 13 can be rotated around the rotating shaft toward the end of the workbench 1 through the motor 2 16, mainly to rotate the connecting disk 12 and the table panel 13 in the direction away from the rotating rod 7 to tilt downward, so as to facilitate the stone to be pushed onto the table panel 13 during loading and then rotated to a horizontal position by the motor for placement, and to facilitate the stone to slide downward for discharging during unloading.

[0030] In the present invention, electric telescopic rods 17 extending vertically upward are fixed at both ends of the workbench 1, and a contact block 171 with a spherical structure is fixed to the top of the electric telescopic rod 17. The contact block 171 contacts the bottom outer wall of the connecting disk 12, so that the contact block 171 is pressed against the bottom outer wall of the connecting disk 12 by the electric telescopic rod 17 to assist in supporting the connecting disk 12, thereby improving the stability of the connecting disk 12 when the connecting disk 12 is placed horizontally for grinding operations or when the connecting disk 12 is placed tilted for loading and unloading.

[0031] In the present invention, a contact rod 18 is fixed between the two rotating rods 7 at a position away from the mounting frame 3, and the outer wall of the contact rod 18 is flush with the end of the rotating rod 7. Figure 6 The first usage state shown is that the connecting plate 12 and the table panel 13 are both placed horizontally, and the contact block 171 contacts the two ends of the bottom of the connecting plate 12 for auxiliary support, so that the position of the grinding plate 501 is adjusted by the linear electric guide rail 11, the arc electric guide rail 9 and the electric push rod 6, and the position of the stone is adjusted by the sliding of the table panel 13 relative to the connecting plate 12 to perform grinding operations;

At this time, the contact rod 18 at the other end of the rotating rod 7 is close to the connection disk 12 and can slide in contact with the bottom of the table panel 13; the magnetic force of the electromagnetic block 20 is reduced to make the table panel 13 slide downward relative to the connection disk 12, and the contact rod 18 is used to assist in supporting the table panel 13, so that the table panel 13 slides downward first to reduce the height of the stone, and then slides downward relative to the table panel 13 to push the stone to move the stone out, so as to facilitate the stone discharge operation and improve safety, and effectively improve the stability of the entire mill during the discharge process;

[0033] During loading operation, Figure 7 In the second use state shown, the connection plate 12 and the table panel 13 are tilted, and the table panel 13 is first slid downward for a certain distance and then fixed by the electromagnetic block 20, and the bottom of the table panel 13 is supported by the rotating rod 7. Then, after the stone is moved to the position of the table panel 13, the connection plate 12 is rotated by the motor 2 16, and the contact rod 18 is continued to move upward by the arc-shaped electric guide rail 9 to support the table panel 13, so that the table panel 13 is restored to a horizontal state, and the table panel 13 is moved inward relative to the connection plate 12 to place the stone in place;

[0034] In summary, the structure of the grinding disc 501 connected by the rotating rod 7 and the relative sliding and rotating arrangement of the connecting disc 12 and the table panel 13 improve the convenience of loading and unloading the stone grinding machine as well as the stability and applicability during use.
