Description
Technical Field
[0001] This utility model relates to the field of drive sprocket technology, specifically to a separate drive sprocket device for a cleaning chain. Background Technology
[0002] A coal mill is a machine that crushes and grinds coal into pulverized coal. The coal grinding process is a process in which coal is crushed and its surface area is continuously increased. To increase the surface area, the intermolecular forces of solid molecules must be overcome, thus requiring energy consumption. During coal mill operation, a sprocket transmission system is used to guide coal blocks into the mill. A sprocket is a solid or spoked gear that meshes with a chain to transmit motion. For example, patent CN205991149U discloses a split-type drive sprocket device for a cleaning chain, including a hub and a toothed disc. The hub consists of an outer ring and an inner ring. A toothed disc and a pressure plate are sequentially installed on the left side of the outer ring. Bolt holes are evenly distributed on the outer ring. The toothed disc is composed of two split toothed discs joined together, with teeth evenly distributed at the top and bolt holes evenly distributed at the inner end. The pressure plate is annular with evenly distributed bolt holes. The pressure plate and toothed disc are bolted to the outer ring of the hub. The number of teeth is 8, and the number of bolts and bolt holes is 10 each.
[0003] When the above device is in use, if the drive sprocket is defective and needs to be replaced, it is not necessary to completely disassemble the cleaning chain reducer, bearing housing, and cleaning chain drive shaft. Only the bolts and pressure plate need to be removed and the two toothed discs can be replaced. However, when disassembling, it is relatively inconvenient to remove the chain on the outer end face of the drive sprocket. At the same time, it is not possible to adjust the spacing of the drive sprocket according to the specifications of the chain, which affects the applicability of the drive sprocket.
