Abstract
The invention discloses an elevation-type material-fetching device for a mining-use automatic-feeding concrete jet machine. The invention relates to the technical field of concrete jet machines. According to the invention, a fixed support is connected with an elevation support through a guide rail and a guide wheel assembly. An elevation cylinder is arranged between the fixed support and the elevation support. Driving sprockets are arranged on the fixed support. Driven sprockets are arranged on the elevation support. Tension sprockets are arranged at the middle of chains. Internal-pressure sprockets are arranged on the fixed support. External-pressure sprockets are arranged on the elevation support. During a material-fetching process, with the reduction of dry materials in a mine car, the elevation cylinder drives the elevation support to move downward, and digging buckets fetch all the concrete dry materials in the mine car. Forward and reverse screws concentrate concrete on two ends of the mine car towards the digging buckets, and the digging buckets fetch all the concrete dry materials from the mine car with no dead angle. With the actions of the internal-pressure sprockets and the external-pressure sprockets, when the working position of the elevation support is at any point, the tightness of the chains is not changed, and the chains are in a tensioned state.
