A stone crushing device for highway construction according to claim 5, characterized in that: The bottom of the inner wall of the work box (1) is connected to the main funnel (765), and a ring block (766) is fixedly connected to the center of the top of the inner wall of the work box (1). Several connecting plates (767) are fixedly connected to the inner walls of the ring block (766), and a conical column (768) is fixedly connected between the four connecting plates (767).

7. A method of using a road construction stone crushing device, applicable to the road construction stone crushing device as described in claim 6, characterized in that, Includes the following steps: Step 1: Place the stone material into the device from the feed cylinder (4), start the motor (71), the motor (71) drives the rotating shaft (72) to rotate, the rotating shaft (72) drives the main grinding wheel (73) to rotate, the main grinding wheel (73) drives the gear (752) to rotate, the gear (752) drives the round block (753) to rotate, the round block (753) rotates and causes the clamping plate (754) to move back and forth, the clamping plate (754) drives the crossbar (755) to move, the crossbar (755) drives the cross plate (757) to move, the cross plate (757) drives the triangular block (758) to move, thus solving the problem of residual material remaining inside the device after the stone material is crushed; Step 2: The stone falls downwards and comes into contact with the secondary funnel (777). The secondary funnel (777) moves downwards, which in turn drives the connecting ring (775) to move downwards. The connecting ring (775) drives the slider (774) to move downwards. During the downward movement of the slider (774), it squeezes the main reset spring (773). The connecting ring (775) drives the connecting block (778) to move downwards. The connecting block (778) drives the extrusion arc plate (779) to move downwards. During the downward movement of the extrusion arc plate (779), it squeezes the airbag (7710). Through the setting of the airbag (7710), the round tube (7711), the water tank (7712), the secondary reset spring (7713), and the pressure plate (7714), the pressure plate (7714) moves upwards. Through the setting of the water tank (7712) and the sprayer (7715), the problem of a large amount of dust during the crushing process is solved. Step 3: During the rotation of the rotating shaft (72), the belt (761) is driven to rotate. The belt (761) drives the rotating sleeve (762) to rotate. The rotating sleeve (762) drives the secondary grinding wheel (763) to rotate. Through the setting of the ring block (766), connecting plate (767), conical column (768), and secondary funnel (777), the problem of stone blockage during crushing is solved.
