Rocker arm mechanism and coal mining machine

The invention provides a rocker arm mechanism and a coal mining machine, and the rocker arm mechanism comprises: a rocker arm assembly; and the crushing assembly is movably connected to the rocker arm assembly, the crushing assembly is used for removing a rock layer outside the ore, and the crushing assembly can move between an operation position and a recovery position relative to the rocker arm assembly. The rocker arm assembly and the crushing assembly are arranged in the rocker arm mechanism, so that when the rocker arm mechanism excavates the ore, the rock layer located outside the ore is removed through the crushing assembly, and then the ore is excavated through the rocker arm assembly. Moreover, the crushing assembly is arranged to be capable of moving between the operation position and the recovery position, so that the crushing assembly can be moved to the operation position when the rock layer needs to be removed, and the crushing assembly can be moved to the recovery position when the ore needs to
