Abstract

The invention provides a scrapper machine, which comprises a machine tail frame and a machine tail wheel, wherein an opening groove is arranged in the machine tail frame, and the machine tail wheel passes through the opening groove to be arranged on the machine tail frame and can do linear movement with a certain distance along the opening groove. The scrapper machine also comprises a linear driver and a pushing moving seat, wherein the linear driving device is fixedly arranged on the machine tail frame, one end of the pushing moving seat is fixedly connected with the linear driving device, and a body is fixedly connected with the machine tail wheel. The scrapper machine provided by the invention has the advantages that the pushing moving seat is driven to move by the linear driving device arranged on the machine tail frame, so the machine tail wheel is pushed to move, the chain tensioning goal is realized, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to coal mine transportation technology, in particular to a scraper machine. Background technique [0002] The scraper machine is an important transportation equipment in the process of coal transportation. It is mainly used in the longwall coal mining face to undertake the transportation task. [0003] The scraper machine is usually equipped with a head sprocket and a tail wheel, and the infinitely circulating scraper chain bypassing the head sprocket and the tail wheel is used as a traction mechanism, and the chute is used as a bearing mechanism to realize dragging and unloading of coal. [0004] After the scraper machine runs for a period of time, the scraper chain will be elongated and deformed due to the tension. When it is extended beyond a certain size, it will affect the operation of the whole machine. The current chain tightening method is realized by setting the reverse rotation of the electric motor or setting the hydra...
