Description

Technical Field

[0001] The utility model relates to the technical field of material distribution for a coal conveying section crusher, in particular to an inlet material distribution device for a coal conveying section crusher. Background Art

[0002] The materials (coal) are relatively concentrated at the entrance of the crusher. There are many types of distributors, including guide plate distributors, electric swing distributors and star feeder distributors. The distributor changes the falling direction of the materials (coal) through its internal structure, causing a change in direction so that the materials enter the crusher as evenly as possible.

[0003] The feeder in the prior art is usually arranged at the entrance of the crusher, and then the coal screened by the drum screen enters the crusher for crushing. However, the existing feeder may have coal blockage, electric swing arm failure and other phenomena, which result in the coal screened by the drum screen not being able to enter the crusher evenly, and it is also inconvenient to clean and maintain after a blockage failure occurs at the feeder. For this reason, we propose a feeder device at the entrance of the coal conveying section crusher. Utility Model Content

[0004] The main purpose of the utility model is to provide an inlet feeding device for a coal conveying section crusher. By improving the coal discharge hopper box of the screening machine and setting a feeding mechanism, the coal and mineral materials screened off at the drum screen can be guided down by the guide plate of the feeding mechanism. The shaft rod driven by a motor at the guide plate can be rotated to change the angle, thereby reducing the frequency of blockage during feeding at the coal conveying section crusher. A side window that is easy to open is provided at the coal discharge hopper box to facilitate cleaning of blocked materials at the coal discharge hopper box. The single-mouth pipe of the screening machine can clean the drum screen with compressed air, thereby increasing the screening rate of materials and reducing the burden on the coal conveying section crusher. Combined with the existing space conditions, the material diversion is even and not easy to be blocked by coal, which can effectively solve the problems in the background technology.
