Detailed Description

The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are easily implemented by those having ordinary skill in the art to which the present invention pertains. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In addition, for the purpose of more clearly describing the present invention, parts not connected with the present invention will be omitted from the drawings.

As shown in fig. 1, a gangue filling and tamping device includes: the device comprises a support bracket 1 and a tamping device 2;

tamping unit 2 sets up at the base end of strutting support 1, and tamping unit 2 includes: the waste rock blocking seat 21, the fixed shaft 22, the swing beam 23, the connecting rod 24, the jack 25 and the fixed block 26;

the waste rock blocking seat 21 is connected with the base 11 of the support bracket 1, the fixed shaft 22 is arranged between two side walls of the waste rock blocking seat 21, the swing beam 23 is in a shape of a 'T', the front end of the transverse end of the swing beam 23 is connected with the curved beam 231, the curved beam 231 is provided with the tamping head 233 through the oil cylinder 232, the oil cylinder 232 controls the tamping head 233 to move, the bottom end of the longitudinal end of the swing beam 23 is rotatably arranged on the fixed shaft 22, the two connecting rods 24 are respectively symmetrically arranged on two sides of the swing beam 23, the front end of the connecting rod 24 is hinged with the tail end of the transverse end of the swing beam 23, the jack 25 is fixedly arranged on the fixed block 26, one end of the shaft of the jack 25 is hinged with the tail end of the connecting rod 24, and the connecting rod 24 drives the swing beam 23 to rotate through the extension and retraction of the shaft of the jack 25, so that the tamping head 233 compacts waste rock passing through a filling area.
