Technical Field

[0001] The utility model relates to the technical field of wharf loading and unloading structures, and particularly relates to a dust suppression type loading hopper based on a sand and gravel loading and unloading wharf. Background Art

[0002] A sand and gravel wharf refers to a wharf used for loading, unloading, storing, processing, selling sand and gravel materials, etc. In a traditional sand and gravel wharf, the wharf body is spaced from the land area, and is connected by a bridge in the middle. A mobile ship unloading device, a front-end belt conveyor and a transfer station are usually arranged on the wharf body. The mobile ship unloading device is used to unload the sand and gravel materials in the cargo ship onto the front-end belt conveyor. The front-end belt conveyor is arranged along the length direction of the wharf and is used to transport the sand and gravel materials in the sand ship to the transfer station. A shore-based belt conveyor is erected between the transfer station and the land area and is used to transport the sand and gravel materials in the transfer station to the land area. Finally, the sand and gravel loading is completed through a loading hopper.

[0003] In the current sand and gravel industry, a large amount of dust is inevitably generated during the loading process of the wharf hopper, which will have a significant impact on the surrounding environment. At the same time, the loading operation often relies on empirical judgment, resulting in the quantity of the loaded materials being difficult to accurately control. To solve these problems, our company has developed an environmentally friendly metering loading hopper, effectively alleviating this problem. Content of the Utility Model
