摘要:
A reciprocating impact slack-drop/rotating/raking multifunctional power shaft, comprising a power shaft section (5), eccentric shaft sections (6), a power take-off (2) comprising a lubricated power take-off (7) and/or a raking power take-off (8), and a power source component (4); the sections (6) comprising bearing separate snap-fitted eccentric shaft sections (6) or bearing integrated sleeved eccentric shaft sections (3); the sections (6) comprising connecting rods (1) comprising separate snap-fitted connecting rods and/or integrated sleeved connecting rods; the power take-off (2) being arranged between the sections (5) and (6), or between the section (6) and the section (6), or at one end of the section (6), or at one end of the section (5); the component (4) driving the section (5) to rotate; the section (6) driving the rod (1) in reciprocating motion; and the section (5) driving the power take-off (2) to operate in rotation.
摘要:
The method for reciprocating punching/raking/loading by a power box on an excavator and the excavator having a power box capable of reciprocating punching/raking/loading, which includes a reciprocating impact power box body and a reciprocating impact box raking device, the reciprocating impact box raking device includes a raking rotary member disposed on the lower portion of the side face of the reciprocating impact power box body and a raking rotary arm disposed on the raking rotary member and driven by it to rotate, the raking end of the raking rotary arm disposed on the reciprocating impact power box body rotates relative to the reciprocating impact power box body to rake the material to an area beyond the surface of the reciprocating impact power box body, the raking rotary arm rakes up the material punched by a reciprocating impact head and moves the material to a material-clearing portion.

A continuous mining method includes operating a vibratory milling machine having a milling head, a base, and a milling tool to oscillate the milling head in a substantially linear reciprocating fashion relative to the base to move the milling tool along a milling axis; and advancing the vibratory milling machine in a work piece in a cutting direction and wherein milling axis is oriented at an attack angle relative to the cutting direction, the attack angle being between about 0 and about 40 degrees.
摘要:
A method and an apparatus for building a thin lining on a tunnel to be excavated. The method includes the steps of boring a slot along an outer periphery of a cross section of the tunnel, filling lining material into the slot so as to form the lining material into the thin lining and removing bedrock surrounded by the thin lining so as to expose the thin lining. The apparatus includes a boring device for boring a slot in the tunnel and an injection device for injecting lining material into the slot. The boring device further includes a hollow frame, a plurality of rods fitted axially movably into the hollow frame, and a drive mechanism for rotating the rods and striking rear ends of the rods.

There is disclosed an impact material fracturing apparatus that is operated by a dynamic mechanical system designed to deliver large amounts of power in a compact system. The apparatus provides a compact system by arranging the drive shaft and fracturing shank in a substantially parallel arrangement in the same plane. The compact arrangement permits the apparatus to be mounted on a swivel joint for 360* of rotation on its mounting so that when mounted on the end of an excavator boom the apparatus has almost unlimited maneuverability.
摘要:
A mounting device having a rigid frame and a stabilizer for carrying a tool in an operable position, and which may be carried by a boom, or by an adapter member which is carried by a boom. Adapter members are provided which may be carried by various types of booms. The mounting device and the adapters are constructed so that the mounting device may be used with all of the adapters.
