Description

Technical Field

[0001] The utility model relates to the technical field of mining crushers, in particular to a mining crushing trough with a convenient replacement of a middle plate and a mining crusher. Background Art

[0002] Crusher is an important equipment in coal mining, among which the crushing trough is an important component of the crusher. It is the movement track of the scraper chain and coal flow, and is the indirect force-receiving body during the crushing process of raw coal.

[0003] The damage of the crushing trough is mainly caused by the wear of the upper edge and the middle plate. Especially during crushing, when large pieces of raw coal are transported on the middle plate of the crushing trough to the bottom of the crushing teeth of the crusher, the crushing teeth crush them by hitting the coal blocks. At this time, the impact and squeezing of the coal blocks on the middle plate of the crushing trough and the impact of the crushed coal blocks falling on the middle plate again on the middle plate are very large. The destructive force borne by the middle plate here is many times greater than that borne by the middle plate at other positions, making it a weak position of the middle plate of the entire middle trough. If, according to the design in the prior art, two middle plates are spliced ​​and welded with the vertical plates on both sides to form an integrated structure with uniform strength, the position of the middle plate facing the crushing teeth of the crusher is the most susceptible to damage and is also the first part to be damaged, thereby making the entire crushing trough scrapped and unusable.
