Method for rotary clearing in stripping tooth holder of mining machine and rotary clearing device in stripping tooth holder

A method for rotary clearing in a stripping tooth holder of a reciprocating impact mining machine, wherein

• (1) a stripping tooth holder is arranged, a rear end of the stripping tooth holder being connected to a reciprocating impact power box power member, and a front end of the stripping tooth holder being provided with a reciprocating impact tooth or a reciprocating impact saw plate;
• (2) a rotary discharging tooth holder hole is provided between the rear end of the stripping tooth holder and the front end of the stripping tooth holder;
• (3) a shifter is arranged, specifically on a clearing drive roller to form a rotary clearer;
• (4) a rotary clearer supporting mechanism is arranged on a reciprocating impact power box or the stripping tooth holder;
• (5) the rotary clearer is arranged in the rotary discharging tooth holder hole of the stripping tooth holder, such that the rotary clearer rotates supported by the rotary clearer supporting mechanism;
• (6) the stripping tooth holder is driven to make the reciprocating impact tooth or the reciprocating impact saw plate strip off material from a material wall;
• and
• (7) the clearing drive roller is made to rotate, and the material stripped off by the stripping tooth holder is spirally pushed by the shifter to a conveyor.
