Description

Technical Field

[0001] The utility model relates to the technical field of sprocket wheels, in particular to a separate sprocket wheel structure which is easy to replace and is used for a transfer machine. Background Art

[0002] A transfer machine is a heavy-duty mechanical equipment widely used in the fields of mining, construction, ports and logistics. Its main function is to transfer bulk materials (such as coal, ore, sand, grain, etc.) from one mode of transportation to another, or from one storage method to another. Through its internal conveying system, the transfer machine can effectively load, unload and transfer materials, thereby improving production efficiency and flexibility in material handling. In the transfer machine, the sprocket plays a vital role. The sprocket is the core component of the transmission system. Through cooperation with the chain, the power is transmitted from the drive device (such as a motor) to the working parts (such as conveyor belts, agitators, etc.). The design of the sprocket directly affects the transmission efficiency and the stability of power transmission.

[0003] As disclosed in Chinese patent announcement number (CN210259951 U), a separate sprocket for a scraper conveyor comprises an upper sprocket and a lower sprocket, a connecting seat is provided at the joint of the upper sprocket and the lower sprocket, a fixing bolt is provided on the connecting seat, sprocket teeth are installed on the outer extension of the upper sprocket and the lower sprocket, and grooves are provided between two adjacent sprocket teeth, a bearing holder is installed on the inner side of the upper sprocket and the lower sprocket, an oil inlet pipe is provided on the side wall of the upper sprocket, a sealing plate is provided on one side of the bearing holder, a fastening screw is provided on the outer extension of the sealing plate, a pressure ring is provided on the other side of the bearing holder, a groove corresponding to the pressure ring is provided on the side wall of the upper sprocket and the lower sprocket, a plurality of hexagon socket screws are provided on the outer extension of the pressure ring, the pressure ring is clamped in the groove, and is fixedly connected to the upper sprocket and the lower sprocket through the hexagon socket screws. The utility model has strong practicality and is worthy of promotion.

[0004] However, as in the above patent, there is still a problem of low efficiency in replacing and installing the sprocket. For example, the sprocket in the above patent cooperates with the pressure ring through the groove during installation, and then a number of hexagon socket screws are installed accordingly, so that the pressure ring is clamped in the groove to achieve replacement and installation. This method not only consumes a lot of maintenance time when disassembling and installing a number of hexagon socket screws, but also most of the sprocket is inside the equipment, and the space is narrow, which further affects the convenience of operation. At the same time, when the sprocket rotates for a long time, it is easy to cause the screws to loosen, affecting the installation efficiency. Utility Model Content

When the sprocket wheel 310 needs to be replaced, the locking of the sprocket wheel 310 and the fixing plate 25 is reversed to release the locking of the sprocket wheel 310 and the fixing plate 25. Then, the connecting sleeve 33 and the fixing sleeve 32 are moved to remove the old sprocket wheel body 22 and install the new sprocket wheel body 22.
