detailed description

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in the figure, the sunken sand and gravel mixing plant in the utility model includes a control system, an aggregate bin 6, a stirring device 1, a material lifting system 2 and a discharge device 3, and the aggregate bin 6 and the stirring device 1 are all arranged in the pit 4 below the ground, the control system and the unloading device 3 are arranged on the ground; there are at least two aggregate bins 6 arranged horizontally on the side of the stirring device 1, and the aggregate The bottom of the bin 6 is provided with a conveyor belt 9 connected to the material inlet of the stirring device 1 , and the stirring device 1 is connected to the unloading device 3 through the material lifting system 2 .

In this embodiment, the control system and the unloading device 3 are arranged on the ground, and the operator can control the lower operation through the monitoring system installed in the pit and the control system on the ground without entering the pit 4, which improves the operation efficiency. safety. The aggregate silo and mixing device 1 are located underground, and the materials on the ground can be transported horizontally; that is, the materials are transported to the aggregate silo, and the aggregate is transported to the aggregate silo by the way of blanking, which eliminates the need for lifting The process reduces the difficulty of feeding and the energy consumption of feeding. By completing the mixing and stirring underground, the external noise pollution is reduced. In addition, since all parts are operated underground, the dust generated during the operation can be closed and recycled, further reducing the external dust pollution.

The material lifting system 2 in this embodiment is a belt conveyor, which is arranged obliquely in the pit, lifts the material lowered by the stirring device to the ground, and loads it into a transport vehicle or a transfer bin through the unloading device 3 . The belt conveyor can be arranged in various forms. According to the topography and height of the pit, it can be arranged in inclined type, inclined + straight conveying type, etc.

Specifically, the aggregate bin 6 has a multi-level structure, which can realize aggregate batching, weighing and unloading. It quantitatively transports the aggregate to the mixing device 1 through the conveyor belt 9, and the inlet of the aggregate bin 6 is not high. On the ground, the material truck directly transports the aggregate to the material inlet of the aggregate bin 6 on the ground, and the aggregate can be added by dropping the material, which saves the lifting process of the aggregate, reduces energy consumption, and saves footprint. The aggregate bin 6 here also has the function of a storage bin. By enlarging its volume and arranging multiple groups side by side, it can directly receive aggregates such as sand and gravel sent by the feeding truck, and realize temporary storage of aggregates such as sand and gravel. Storage, in order to realize the continuous feeding of the conveyor belt to the mixing device, save waiting time and improve work efficiency.
