[0050] Working principle:

[0051] Firstly, the sand and stones are conveyed into the loading hopper 2 according to the specified amount through the conveying belt of the loading equipment 3, the control valve 41 is controlled to control the discharging speed of the sand and stones in the loading hopper 2, so that the sand and stones enter the inner cavity of the flow regulating assembly 4 from the discharging hopper 1;

[0052] Then, the plurality of hydraulic telescopic rods 6 are started, the flow hopper 42 is driven to elongate through the telescopic adjustment of the hydraulic telescopic rod 6, the mounting sleeve plate 51 moves towards the bottom, drives the discharging assembly 7 rotatingly connected at the bottom to simultaneously perform lifting movement, when the hexagonal hole on the positioning clamping plate 52 and the positioning clamping piece 53 are mutually sleeved, the positioning clamping piece 53 limits the positioning clamping plate 52, at this time, the conical gear ring 73 and the conical rack 812 are in mutual abutment and engagement;

[0053] Finally, the driving motor set 811 is started, the gear is driven through the driving motor set 811, the gear meshes to drive the bevel gear 812 to slide horizontally in the limiting hole, when the bevel gear 812 moves, the whole discharging assembly 7 can be driven to rotate, through the rotation of the discharging assembly 7, when the sand and stone is discharged through the plurality of first conical discharging ports 711 and the second conical discharging ports 712 and the bottom discharging port of the rotary bucket 72, the discharged sand and stone can be in the annular rotating state, compared with the traditional direct discharging mode, the rotating discharging mode can avoid the accumulation of sand and stone at a single discharging point, and the driver does not need to continuously start the vehicle to move back and forth to adjust the position, the cumbersome process in the loading process is reduced, and the plurality of rotating discharging modes can make the sand and stone after discharging be more evenly distributed in the car bucket, improve the loading uniformity of the car bucket, avoid the problem that the transport vehicle tilts on one side due to loading deviation, improve the loading quality and also improve the safety of vehicle transportation;
