Problems solved by technology

And use the slots on the grinding wheel to increase the crushing force on the stone, but the spacing between the slots on the grinding wheel is relatively large, so the crushing efficiency is low; if you want to improve the crushing efficiency of the grinding wheel, you must increase the speed of the grinding wheel. The increase of the rotating speed of the grinding wheel will inevitably cause the rotating shaft of the grinding wheel to generate a large amount of heat under high-speed rotation, which will damage the rotating shaft of the grinding wheel, so it has to stop for a period of time to dissipate heat, so the crusher cannot meet the requirements of long-term work. needs
Furthermore, the crusher cannot squeeze and stir the stones, and the stones are not easy to enter the rollers for rolling, so the working efficiency of the stone crusher is low and cannot meet people's needs.
In addition, a large amount of dust is generated during the crushing process of the stone, which will cause air pollution, and the dust will be inhaled by the operating workers, endangering the health of the operating workers

Abstract

The invention discloses a self-lubricating bearing and a stone crushing device applying the self-lubricating bearing. The device comprises a first shaft sleeve and a second shaft sleeve which sleeve arotating shaft, wherein inner walls of the first shaft sleeve and the second shaft sleeve are in clearance fit with an outer side wall of the rotating shaft, outer sides of the first shaft sleeve andthe second shaft sleeve are sleeved with bases, inner walls of the bases are in sealed connection with the outer side walls of the first shaft sleeve and the second shaft sleeve, an annular cavity isformed between the first shaft sleeve and the second shaft sleeve, an oil storage block made of a flexible microporous material is arranged in the annular cavity, and the oil storage block is attached to an outer side wall of the rotating shaft and used for lubricating the outer side wall of the rotating shaft. The self-lubricating bearing has the advantages that the self-lubricating bearing canautomatically lubricate the rotating shaft, friction force of the rotating shaft is reduced, heat generated when the rotating shaft rotates at a high speed is reduced, the rotating shaft is preventedfrom being damaged, and the stone crushing device applying the self-lubricating bearing is high in crushing efficiency.

Description

technical field [0001] The invention relates to the technical field of stone crushing, in particular to a self-lubricating bearing and a stone crushing device for its application. Background technique [0002] Stone is one of the indispensable materials in construction engineering, road construction, chemical industry and other fields. Stones are generally taken by quarry machines, and then crushed into a suitable size by crushing process before they can be used by people. The stone crushing process is generally that the stone is uniformly sent to the coarse crusher by the feeder for preliminary crushing, and then the produced coarse material is transported to the crusher by the belt conveyor, and the crusher is further crushed, and the finely crushed stone is sent to the crusher. The vibrating screen screens out stones of different specifications, and the stones that do not meet the particle size requirements are returned to the crusher for further crushing. [0003] The ...
