Targeted false rock wall used for experiment of mine excavation equipment

The invention belongs to coal mine mechanical experimental equipment, and particularly relates to a targeted false rock wall used for the experiment of mine excavation equipment. A movable base (13) is installed on two parallel guide rails (9). A guard rail (8) is arranged on the front bottom edge of the movable base (13). A first transverse lead screw nut (14) and a second transverse lead screw nut (14-1) are fixed in the middle of the bottom part of left and right base rib frames (13-1). A vertical lead screw coupler shell (15) is fixed on two parallel base upper frame plates (13-3). The output shaft of a vertical lead screw gear motor (1) is connected at the top end of the vertical lead screws (2) in the vertical lead screw coupler shell (15) by using a second coupler (15-1). An upper first vertical lead screw nut (3) and a lower second vertical lead screw nut (3-1) sleeve the two parallel vertical lead screws (2). According to the targeted false rock wall used for the experiment of the mine excavation equipment, the mechanical structure acts as the main body, the mechanical part can be permanently used and only prefabricated rock blocks require to be replaced in repeated use so that various different types of lithology can be respectively simulated.
