Description

Technical Field

[0001] The utility model relates to the field of dust removal spraying mechanisms, and particularly relates to a dust removal spraying mechanism for a stone conveyor. Background Art

[0002] During the stone processing, large stones need to be crushed into small pieces and then transported to a truck for filling through a stone conveying pipe. Since the stone crushing process is not dust-removed, a large amount of dust will be raised during the filling of the truck, causing environmental pollution.

[0003] After retrieval, an environmental protection dust removal device for mine exploitation with the publication number of CN202123337699.5 is specifically disclosed, which includes a dust removal box body. Inside the upper end of the dust removal box body, a vibration frame is installed. Inside the middle of the vibration frame, a vibrating screen is fixedly installed. At the lower end surface of the vibration frame, a vibration motor is fixedly installed. At the bottom end of the vibration frame, an arc-shaped retention seat is installed. Inside the arc-shaped retention seat, three conical water collection seats are evenly installed. At the bottom end of the conical water collection seat, a second conveying pipe is installed. The bottom ends of the three second conveying pipes are all connected to the dust removal box body through pipe end seals. At the upper end of the dust removal box body, a feeding port is fixedly installed. Inside the feeding port, a spraying pipe is arranged. One end of the spraying pipe is installed with a first conveying pipe. Inside the middle of the dust removal box body, a filter plate is installed. The utility model effectively avoids the generation of dust by dust removal and cleaning during the stone screening process, and is convenient for recycling and filtering water.

[0004] However, the above device still has certain defects. For example, after the stone is dust-removed by spraying, its surface is still in a wet state. After discharging and contacting with the outside air, impurities such as dust and soil are easily adhered to the stone surface again, and a large amount of dust will still be raised during the secondary discharging or filling, causing environmental pollution and poor practicability.

[0005] Therefore, it is very necessary to invent a dust removal spraying mechanism for a stone conveyor to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a dust removal spraying mechanism for a stone conveyor, which can effectively solve the above technical problems.
