The invention discloses a crushing particle size adjusting device and a mining wheel crusher. The crushing particle size adjusting device comprises a crushing shaft seat, a movable cushion block assembly and a jacking assembly, wherein the crushing shaft seat is detachably connected with a crusher groove body; the jacking assembly is connected with the crusher groove body, is positioned below thecrushing shaft seat, and is used for adjusting the height of the crushing shaft seat separated from the crusher groove body; the cushion block assembly comprises at least one movable cushion block which is horizontally arranged and detachably connected with the top of the crushing shaft seat, and the movable cushion block can be further detachably connected with the bottom of the crushing shaft seat; and the height of the crushing shaft seat on the crusher groove body is changed along with the number of the movable cushion blocks located at the bottom of the crushing shaft seat. The crushing particle size adjusting device not only is compact in structure, but also can avoid the time consumption for conveying the movable cushion blocks, and effectively reduces the labor intensity of workers.
Description
technical field [0001] The invention relates to the technical field of coal mine engineering machinery, in particular to a crushing particle size adjusting device and a mining wheel crusher. Background technique [0002] The mining wheel crusher is mainly used for high-yield, high-efficiency comprehensive mechanized working face. When working, one end of the mining wheel crusher is connected with the input trough of the trough loader, and the other end is connected with the output trough of the trough loader. The wheel crusher is used to break the coal in the middle of the trough loader. Among them, according to the output, required coal particle size and input coal block size, the staff will adjust the crushing particle size by adjusting the height of the crushing shaft group of the crusher. [0003] At present, the most commonly used particle size adjustment device in China uses four sets of hydraulic cylinders to lift the entire crushing tank, and then adjusts the crushi...
