METHOD FOR ROTARY REMOVING OF MATERIALS IN MATERIAL STRIPPING RACK OF MINING MACHINE AND DEVICE FOR ROTARY REMOVING OF MATERIALS IN MATERIAL STRIPPING RACK

WIPO Patent Application WO/2021/047580

A1

A method for rotary removing of materials in a material stripping rack of a mining machine and a device for rotary removing of materials in a material stripping rack for implementing the method. The device for rotary removing of materials comprises a reciprocating impact power box (2), a material stripping rack (3), a rotary material remover supporting mechanism (4), and a rotary material remover (5); the rotary material remover (5) comprises a material tripper device (6) and a material removing driving roller (7), the reciprocating impact power box (2) comprises a reciprocating impact power box power component (8), the reciprocating impact power box power component (8) supports and drives the material stripping rack (3), the rotary material remover supporting mechanism (4) is provided on the reciprocating impact power box (2) or the material stripping rack (3), the material stripping rack (3) has a rear end connected to the reciprocating impact power box power component (8), and has a front end on which reciprocating impact teeth (9) or a reciprocating impact saw plate (10) are provided, the material stripping rack (3) comprises a rotary material discharge rack hole (11), the rotary material remover (5) is provided in the rotary material discharge rack hole (11) of the material stripping rack (3), the rotary material remover supporting mechanism (4) supports the rotary material remover (5) to rotate, the material removing driving roller (7) rotates to drive the material tripper device (6), the material tripper device (6) rotates the materials dropped caused by the impact from the material stripping rack (3) out of the rotary material discharge rack hole (11), thereby reducing the resistance to the reciprocating operation of the material stripping rack and the traveling of the machine body.
