Description

FIELD OF THE INVENTION

The present invention relates to the field of machinery, in particular to a method for reciprocating punching/raking/loading by a power box on an excavator, and an excavator having a power box capable of reciprocating punching/raking/loading.

BACKGROUND OF THE INVENTION

At present, during reciprocating impact excavation, reciprocating impact teeth are vertical to a material to be mined to carry out reciprocating impact punching, the reciprocating impact excavation is high in block rate, energy-saving, environmentally friendly and high in efficiency, so the reciprocating impact excavation has a broad application prospect. A reciprocating impact excavator produced according to the principle is about to be popularized and applied. It is found in the promotion process of the product that, although the mining efficiency of the reciprocating impact excavator is very high, since the extension directions of reciprocating impact teeth and a rocker arm thereof are parallel, the reciprocating impact teeth cannot transfer a material to the shovel plate of a roller excavator through helically disposed rotary teeth just like the rotary teeth of a rotary milling punching type roller excavator, the material quickly mined by the reciprocating impact excavator cannot be cleared away in time, resulting in serious material accumulation, since the material is away from the feed opening of a first transporter for a longer distance, the first transporter cannot be sufficiently fed in time; and meanwhile, an isolation layer is formed by the excessive accumulation of the material on a mining surface, so the reciprocating impact teeth are difficult to touch the material to be mined, thereby hindering the continuous mining of the reciprocating impact head and reducing the mining efficiency. At present, only the rocker arm is used for shifting the material to the shovel plate on the application site, since the motion track of the shifted material is inconsistent with the material clearing direction of a material clearing mechanism, a large number of materials cannot be shifted to the shovel plate, and the material clearing efficiency is lower, and even the rocker arm and the impact head are seriously broken due to frequent material shifting, if the material punched by reciprocating impact is manually cleared, blocks are liable to drop to damage the material clearing personnel because the top of a roadway is not supported after excavation, and the manual clearing efficiency is low. Because the excavator is mainly used for excavating the roadway, to save the roadway excavation cost, the section of the roadway is reduced as much as possible, the section space is only enough for the construction of the excavator when excavating the roadway, a reciprocating hoeing machine, a raking/loading machine or other material clearing equipment cannot be disposed or used at the roadway excavation site, if the reciprocating hoeing machine, the raking/loading machine or other material clearing equipment is disposed and used, the huge machine body of the reciprocating hoeing machine, the raking/loading machine or the like need to operate in the roadway with the reciprocating excavator in parallel, the original high roadway excavation cost is exponentially increased, if a material clearing device is disposed on the machine body of the excavator, the rocker arm of the material clearing device will generate mutual interference with the rocker arm of a reciprocating impact box, and the volume of the reciprocating impact excavator is greatly increased, so that the reciprocating impact excavator cannot adapt to onsite demands due to large volume and complex structure. Since the original reciprocating impact excavator does not solve the above problems for all the time, the reciprocating impact excavator is not truly promoted and applied so far. To fundamentally solve the above problems, widely apply the reciprocating impact excavator, which is energy-saving, environmentally friendly, efficient and capable of improving the material use value, and make a contribution to mankind, the present invention provides a method for reciprocating punching/raking/loading by a power box on an excavator and an excavator having a power box capable of reciprocating punching/raking/loading.
