Drive device and application of blade star wheel in roadheader

Abstract

The invention relates to an insertion board star-wheel driving device in a heading machine and application of the insertion board star-wheel driving device. The driving device comprises a power source, a tightening flange, a rotating bearing and a planet gear system, wherein the planet gear system comprises three planet gears which are uniformly distributed, an inner gear ring of the planet gear system is fixedly connected with the tightening flange through a bolt, the tightening flange is fixedly connected with a runner plate through a bolt, and the rotating bearing is arranged between the inner gear ring and a planet carrier; a sun gear shaft of the planet gear system is an input shaft; one planet gear in the three planet gears is a driving planet gear, a shaft pin of the driving planet gear is an output shaft, the output shaft is supported on the planet carrier through a bearing, the driving planet gear is fixedly connected with the output shaft, the output end of the output shaft is fixedly connected with the center of a star wheel to form a star wheel assembly, when being paired for use in an insertion board, the rotation directions of the two star wheel assemblies are opposite to each other in the autorotation and revolution processes, and the difference of an initial phase of the autorotation axes of the two star wheel assemblies on a revolution orbit is 180DEG in assembling.

Description

technical field [0001] The invention relates to a cantilever roadheader, in particular to a shovel star wheel mechanism of the roadheader. Background technique [0002] Most of the cantilever roadheader shovels use star wheels to transport the cut materials. With the country's emphasis on the coal mine production and operation environment, roadheaders use spray to remove dust during the cutting process. A large amount of dust removal water and the cut materials Coal is mixed to form a paste-like slime, which is easy to stick to the star wheel, resulting in low transportation efficiency. At present, the driving method of the star wheel is generally that the driving device is driven by the gear transmission mechanism and rotates in situ. When the slime cannot be effectively transported and accumulates, its viscosity makes it stick. Although the star wheel can transport the bottom slime away , but the upper layer of coal slime forms a shell, and the star wheel that can only ro...

[0002] Most of the cantilever roadheader shovels use star wheels to transport the cut materials. With the country's emphasis on the coal mine production and operation environment, roadheaders use spray to remove dust during the cutting process. A large amount of dust removal water and the cut materials Coal is mixed to form paste-like slime, which is easy to stick to the star wheel, resulting in low transportation efficiency

At present, the driving method of the star wheel is generally that the driving device is driven by the gear transmission mechanism and rotates in situ. When the slime cannot be effectively transported and accumulates, its viscosity makes it stick. Although the star wheel can transport the bottom slime away , but the upper layer of coal slime forms a shell, and the star wheel that can only rotate in situ cannot make the shelled upper layer of coal slime collapse downward in time, resulting in further accumulation of coal slime, which is not conducive to production
