Problems solved by technology

[0003] Traditional mechanical rotary sealing devices do not have a good sealing structure. Due to the high-speed rotation during the working process, fine dust and debris will inevitably enter the device, resulting in damage and potential safety hazards after long-term use. , and it is not convenient to work

Abstract

The invention discloses a rotary sealing structure for coal mine machinery in the technical field of coal mine machinery. The rotary seal structure for coal mining machinery includes a central shaft, a first housing is sheathed on the outside of the central shaft, a second housing is fixed on one side of the first housing, and the second housing is sleeved in the center Outside the rotating shaft, an auxiliary mechanism is arranged inside the second housing. The rotary sealing structure for coal mine machinery will drive the second gear to rotate when the central shaft rotates, and then drive the limit ring to rotate, and then use the moving belt to slide and connect with the limit ring and limit the limit to surround the inside of the box, so that It will use the moving belt of the limit ring to bypass the inside of the box, and then add lubricating oil to the inside of the box in advance, so that the limit ring will pass through the inside of the lubricating oil, then wet the sponge block, and then use Some of the dust is adhered to by the wetted sponge block, so that the dust will not continue to enter.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery, in particular to a rotary sealing structure for coal mine machinery. Background technique [0002] Machinery is the general term for machines and mechanisms. Machinery is a tool device designed to help people reduce work difficulty or save energy. Items such as chopsticks, brooms, and tweezers can be called simple machines; and two or more simple machines are complex machines. And complex machinery is called a machine. In fact, from the point of view of structure and movement, there is no difference between machinery and machinery, which are collectively referred to as machinery. The working conditions and environment of the fully mechanized mining face in coal mines are relatively poor, and particles such as water, coal powder, and sand are driven by scraper conveyors The rotating parts of the sprocket assembly, shearer cutting drum and other components have accumulated for a long ...
