A detector 4 for detecting the accumulated height of gravel in the corresponding chamber is provided at the outlet of the first conveyor belt 1. The detector 4 is electrically connected to the controller of the adjusting mechanism through a circuit. The controller is configured to move the outlet of the first conveyor belt to the next chamber or stop the first conveyor belt 1 in the last chamber when the detector 4 detects that the accumulated height of gravel in the corresponding chamber reaches a set height. N is a natural number greater than 1. The specific circuit structures of the controller and the detector 4 belong to the prior art and will not be described in detail herein.

[0026] Above the storage bin 3, a frame body 5 is provided. The first conveyor belt 1 is arranged on the tensioning rollers of the frame body 5 in a circulating and rolling manner. The first tensioning roller is located above the first bin chamber. The first tensioning roller is connected to a tensioning roller driver 51, and the tensioning roller driver is electrically connected to the controller. The second tensioning roller is located above the last bin chamber. The adjusting mechanism is movably arranged on the frame body 5. A deflecting roller 62 and a driving roller 61 are arranged on the adjusting mechanism. The first conveyor belt 1 is connected to the deflecting roller 62 and the driving roller 61. The outlet of the first conveyor belt 1 corresponds to the driving roller 61. The tensioning roller driver 51 is a tensioning roller driving motor. The output wheel of the tensioning roller driving motor drives the tensioning roller to rotate through a gear set.

[0027] The adjusting mechanism is specifically as follows: On the frame body 5, a slide rail is provided. On the slide rail, a pulley car 6 is provided. On the pulley car 6, a vehicle frame and a pulley driver are provided. The deflecting roller 62 and the driving roller 61 are arranged on the vehicle frame. The driving roller 61 is connected to a driving roller transmission motor, and the driving roller transmission motor is electrically connected to the controller. The detector 4 is arranged on the vehicle frame on one side of the driving roller 61. The pulley driver is connected to the controller through a circuit. A blanking hopper 63 is arranged on the vehicle frame below the outlet of the first conveyor belt. An auxiliary support 64 is arranged on the pulley car 6. Auxiliary rollers 65 are arranged at intervals on the auxiliary support 64. Each group of auxiliary rollers 65 is in contact with the first conveyor belt 1 at the corresponding position. Each of the auxiliary rollers 65 is composed of three guide rollers. The two guide rollers located on both sides of the three guide rollers converge towards the middle position, and the three guide rollers are distributed in a wing shape. The specific structure of the pulley driver is that a driving motor 66 is arranged on the vehicle frame.

[0028] Frame body auxiliary rollers are distributed at intervals on the frame body 5. The frame body auxiliary rollers are also composed of three roller bodies, and have the same arrangement structure as the auxiliary rollers 65. The second conveyor belt 2 is perpendicular to the conveying direction of the first conveyor belt 1. At the outlet of the second conveyor belt 2, a guiding hopper 21 is provided to enable the crushed stones to fall on the first conveyor belt 1. On the frame body 5 corresponding to each bin chamber, a guiding plate 52 is provided to change the falling direction of the crushed stones.

[0029] Working principle: The crushed stones fall onto the first conveyor belt from the second conveyor belt. The tensioning roller driver drives the first conveyor belt to rotate, and the crushed stones fall from the first conveyor belt into the first chamber. When the detector detects that the height of the crushed stones in the first chamber reaches the set value, the controller stops the tensioning roller driver and drives the driving roller to rotate, thereby driving the first conveyor belt to rotate in the reverse direction, and the crushed stones fall into the second chamber from the side of the driving roller. When the height of the crushed stones in the second chamber reaches the set height, the controller drives the pulley car to move forward. The pulley car stops until the outlet of the first conveyor belt is aligned with the next chamber. The crushed stones fall from the first conveyor belt into the new chamber and circulate in turn. After the height of the crushed stones in the last chamber reaches the set height, the controller controls the device to stop working.
