7. A crushing method for a stone processing crusher, characterized in that, The crushing method of the stone processing crusher, applicable to the stone processing crusher according to claim 6, includes the following steps: Step 1: When crushing the stone, add stone into the crushing frame (1) through the feeding frame head (2), and start the motor box (607) to drive the rotating crushing rollers (605) on both sides to rotate. The rotating crushing rollers (605) on both sides crush the falling stone. When adjusting the size of the crushed stone, start the small electric telescopic rods (601) on both sides to drive the mounting shafts (602) on both sides to move. The mounting shafts (602) drive the rotating crushing rollers (605) on both sides to move and adjust. When the mounting shafts (602) move, they drive the stabilizing slider (606) to the stabilizing groove (604). Internal sliding: When the stabilizing slider (606) slides inside the stabilizing groove (604), it will drive the moving scale rod (603) to move. The operator can observe the size of the moving distance of the rotating crushing roller (605) through the moving scale rod (603). The stability of the installation shaft frame (602) and the moving crushing roller (605) is increased by the sliding of the stabilizing slider (606) inside the stabilizing groove (604). In addition, the spacing during crushing can be adjusted according to the size of the crushed stone, so the size of the crushed stone can be adjusted. Step 2: When a large amount of stone accumulates at the top of the rotating crushing roller (605) and cannot be crushed, the stone will move towards the movable baffle (401) and push the movable baffle (401) towards the mounting spring (402), squeezing the mounting spring (402) so that the contact ball (403) contacts the touch switch (404). The touch switch (404) simultaneously activates the electric push rods (301) on both sides, causing the electric push rods (301) on both sides to simultaneously push the crushing plates (302) on both sides towards the opposite side. When one side moves, it contacts and squeezes the stone accumulated at the top of the rotating crushing roller (605), and crushes the stone. When the crushing plates (302) on both sides move to the opposite side, the movable crushing plates (303) on both sides lose their restraint. The movable crushing plates (303) are pushed down by the push spring (304) in a compressed state, and the movable crushing plates (303) move to the upper end of the rotating crushing roller (605) on both sides, thereby further crushing the stone accumulated at the top of the rotating crushing roller (605). Step 3: Simultaneously, when the crushing plates (302) on both sides move to the opposite side, the connecting rope (501) will move and stretch, and the traction slider will slide to the top of the inner cavity of the moving slide groove (503). The traction slider will drive the movable mounting rod (502) and the fixed top rod (504) to move upward, and the circuit of the positioning electromagnetic block (509) at the front and rear ends will be disconnected by the touch switch (404), so that the positioning electromagnetic block (509) loses its magnetism, and the tension spring (507) in the stretched state will pull... The movable slider (506) and the movable top rod (505) move away from the movable slide groove (503) and make the docking block (13) fit into the docking interface (12), increasing the firmness of the docking of the two movable top rods (505). After the movable top rods (505) on the front and rear sides dock, the fixed top rod (504) and the movable top rod (505) move upward and move between the rotating crushing rollers (605) on both sides, which will push out the stone stuck between the rotating crushing rollers (605).
