[0022] The outside surface of rotating arm 5 is fixedly arranged with first gear 11, one end of transmission rod 9 is fixedly arranged with second gear 12, first gear 11 and second gear 12 are engaged with each other, through the linkage of first gear 11 and second gear 12, when rotating arm 5, gate 6 rotates and opens, drives transmission rod 9 and stirring rod 10 to rotate together;

[0023] The diameter of the first gear 11 is greater than the second gear 12, so that the first gear 11 can drive the second gear 12 to rotate at high speed, that is, as long as the rotating arm 5 and the shutter 6 are slightly rotated, the first gear 11 can drive the second gear 12 to rotate in a large range, so that the rotating range of the transmission rod 9 and the stirring rod 10 can be increased, and the stirring effect can be improved.

[0024] The storage bin 3 is fixedly provided with a ladder 13 on the surface, and the ladder 13 can facilitate manual climbing to observe the storage condition in the storage bin 3.

[0025] The pressure detection device 14 is fixedly arranged between the bottom plate 1 and the column 2, and the pressure detection device 14 can play a weighing role. When the shutter 6 moves and the gravel in the storage bin 3 leaks out to a predetermined weight, the hydraulic cylinder 7 can be retracted to block the discharge port 4, so that the function of quantitatively discharging gravel can be achieved, thereby facilitating the subsequent concrete batching and mixing work.

[0026] Working principle: when the device is used, the excavator or forklift can pour gravel into the storage bin 3, so that the storage bin 3 can store gravel. When batching and discharging are needed, the hydraulic cylinder 7 is elongated to push the rotating arm 5 and the shutter 6 to rotate and open to the two sides, so that the shutter 6 no longer blocks the lower end of the discharge port 4, so that the discharge port 4 can discharge gravel.
