[0013] Another object of the present invention is to provide a method for using a jaw crusher anti-jamming device in a coarse crushing workshop of a sandstone system, comprising the following steps: Step 1: When in use, the feeding conveyor belt and the driving gear 1 are connected by rotation. The driving gear 1 is driven by the motor 1, and the feeding conveyor belt and the driving gear 1 are rotated, so that the feeding conveyor belt transports the stone to the jaw crusher mechanism for crushing. The jaw crusher driving device is electrically connected with the eccentric shaft and the eccentric seat. When the material enters between the static jaw and the movable jaw in the crushing box, the movable jaw on one side makes periodic reciprocating motion relative to the fixed static jaw under the action of the eccentric shaft and the eccentric seat. When the movable jaw approaches the static jaw, the stone is clamped between the two jaw plates for compression. As the movable jaw continues to move, the stone is further crushed and sheared by the jaw plate, and the size of the stone blocks gradually decreases. When the movable jaw moves away from the static jaw, the material that has been crushed to a small enough size is discharged from the bottom of the crushing box under the action of gravity, completing a crushing cycle. By setting a dredging mechanism, when the material is stuck at the jaw crushing mechanism, the hydraulic controller controls the hydraulic telescopic rod to make the hydraulic telescopic rod move up and down with the dredging seat. Through the up and down extension of the dredging seat, the stone stuck between the static jaw and the movable jaw is squeezed downward and crushed by the movable jaw. Step 2: Then, by setting up a moving mechanism, if the dredging mechanism cannot dredge the blockage, the bidirectional threaded shaft is driven by the dual-drive motor box to make a threaded rotation connection between the bidirectional threaded shaft and the moving seat, and the jaw crushing drive equipment is moved left and right by the moving seat to open the distance between the static jaw and the movable jaw, so that the stuck stone can leak out from the opened distance. By setting up a discharge mechanism, the driving gear two is rotationally connected to the discharge conveyor belt under the drive of the motor two, and the crushed stone crushed by the jaw crushing mechanism is sequentially conveyed through the discharge conveyor belt.

[0014] The beneficial effects of the present invention are: 1. When the present invention is in use, a feeding mechanism is provided, a feeding conveyor belt and a driving gear 1 are rotatably connected, the driving gear 1 is driven by a motor 1, and the feeding conveyor belt and the driving gear 1 are rotated, so that the feeding conveyor belt can transport stones to the jaw crushing mechanism for crushing. The feeding mechanism can control the flow rate and speed of the material, so that the jaw crushing mechanism can evenly receive the material, which is conducive to the stability of the crushing effect and can prevent blockage during crushing to a certain extent.

[0015] 2. When the present invention is in use, a jaw crushing mechanism is set up, and the jaw crushing driving device is electrically connected to the eccentric shaft and the eccentric seat. When the material enters between the static jaw and the movable jaw in the crushing box, the movable jaw located on one side makes periodic reciprocating motion relative to the fixed static jaw under the action of the eccentric shaft and the eccentric seat. When the movable jaw approaches the static jaw, the stone is clamped between the two jaw plates and crushed. As the movable jaw continues to move, the stone is further crushed and sheared under the action of the jaw plates, and the size of the stone blocks gradually decreases. When the movable jaw is away from the static jaw, the material that has been crushed to a small enough size is discharged from the bottom of the crushing box under the action of gravity, completing a crushing cycle.

[0016] 3. When the present invention is in use, by setting up a dredging mechanism, when material jamming occurs at the jaw crushing mechanism, the hydraulic telescopic rod can be controlled by the hydraulic controller, so that the hydraulic telescopic rod can move up and down with the dredging seat. Through the up and down extension of the dredging seat, the stone stuck between the static jaw and the movable jaw can be squeezed downward and crushed by the movable jaw.

[0017] 4. When the present invention is in use, by setting a moving mechanism, if the dredging mechanism cannot dredge the blockage, the bidirectional threaded shaft is driven by the dual-drive motor box, so that the bidirectional threaded shaft and the moving seat are threadedly connected. The moving seat drives the jaw crushing drive device to move left and right, so as to open the distance between the static jaw and the movable jaw, so as to facilitate the jammed stone to leak out from the opened distance. The overall operation is simple and convenient.

[0018] When the present invention is in use, a feeding mechanism is provided, and driving gear 2 is rotationally connected with the feeding conveyor belt under the drive of motor 2. The crushed stones crushed by the jaw crushing mechanism can be sequentially conveyed through the feeding conveyor belt. The feeding mechanism receives the materials evenly, which can prevent the stone outlet from being blocked to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

The method for using the jaw crusher anti-jamming device in a coarse crushing workshop of a sandstone system according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: When in use, the feeding conveyor belt (201) and the driving gear 1 (202) are connected in rotation, and the driving gear 1 (202) is driven by the motor 1 (204). The feeding conveyor belt (201) and the driving gear 1 (202) are rotated, so that the feeding conveyor belt (201) transports the stones to the jaw crushing mechanism (1) for crushing. The jaw crushing driving device (108) is electrically connected to the eccentric shaft (105) and the eccentric seat (106). When the material enters between the static jaw (102) and the movable jaw (103) in the crushing box (101), the movable jaw (103) located on one side performs periodic reciprocating motion relative to the fixed static jaw (102) under the action of the eccentric shaft (105) and the eccentric seat (106), and the movable jaw (103) approaches the static jaw (102). When the movable jaw (103) moves away from the stationary jaw (102), the material that has been crushed to a small enough size is discharged from the bottom of the crushing box (101) under the action of gravity, completing a crushing cycle. By providing a dredging mechanism (3), when the material is stuck at the jaw crushing mechanism (1), the hydraulic controller (304) controls the hydraulic telescopic rod (303) so that the hydraulic telescopic rod (303) moves up and down with the dredging seat (301). Through the up and down extension of the dredging seat (301), the stone stuck between the stationary jaw (102) and the movable jaw (103) is squeezed downward and crushed by the movable jaw (103); Step 2: Then, by setting a moving mechanism (4), if the dredging mechanism (3) cannot be dredged, the bidirectional threaded shaft (402) is driven by the dual-drive motor box (404), so that the bidirectional threaded shaft (402) and the moving seat (401) are threadedly connected, and the jaw crushing driving device (108) is moved left and right by the moving seat (401), so as to open the gap between the static jaw (102) and the movable jaw (103), so that the stuck stone can leak out from the opened gap. By setting a discharge mechanism (5), the driving gear 2 (502) is driven by the motor 2 (505) to be rotationally connected with the discharge conveyor belt (501), and the crushed stone crushed by the jaw crushing mechanism (1) is sequentially conveyed through the discharge conveyor belt (501).
