Title:
RECIPROCATING IMPACT BEVEL DISCHARGING SHOVEL OF RECIPROCATING IMPACT MINING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/210881
Kind Code:
A1
Abstract:
A reciprocating impact bevel discharging shovel of a reciprocating impact mining machine, comprising a reciprocating impact box and a reciprocating impact bevel discharging shovel (1). The reciprocating impact box comprises a reciprocating impact box body (3), a reciprocating impact power element, and a reciprocating impact guide element (2). The reciprocating impact power element is provided in the reciprocating impact box body (3), and is supported by the reciprocating impact box body (3) to drive the reciprocating impact guide element (2). One end or both ends of the reciprocating impact guide element (2) extend out of the reciprocating impact box body (3). The reciprocating impact bevel discharging shovel (1) comprises a main gear base (5), main impact gears (4), a side discharging gear wing plate (6), and side discharging bevels (7). The main gear base (5) is provided at the end portion of the reciprocating impact guide element (2) extending out of the reciprocating impact box body (3). The main impact gears (4) are provided at the top of the main gear base (5). The thickness of the side discharging gear wing plate (6) is less than that of the main gear base (5) to reduce the height of a discharging surface of the reciprocating impact bevel discharging shovel (1). The side discharging bevels (7) are alternately or symmetrically provided or sequentially provided on the side discharging gear wing plate (6). The tops of the side discharging bevels (7) extend out of a plane of one side of the side discharging gear wing plate (6), so that the impacted materials are discharged from a gap where the side discharging bevels (7) are higher than the side discharging gear wing plate (6), and the resistance of the materials to the reciprocating impact bevel discharging shovel (1) is reduced.
