Problems solved by technology

[0004] Some impact head coal shearers also adopt rocker-type lifting mechanism to lift. When the impact head needs to be turned around, because the length of the impact head and the rocker arm is too large, it is difficult to turn the impact head for return mining in narrow coal lanes. , because the rocker arm uses swing to adjust the coal mining height, so when the impact head adjusts the upper and lower mining heights, the impact angle of the impact

Abstract

The invention specifically relates to a method for retaining vertical impact of an impacting mechanism and a vertical-lift impact-cutting digger implementing the method, belonging to the field of machinery, especially to the field of mining. The digger comprises a body, the impacting mechanism and a vertical lift mechanism, wherein the impacting mechanism comprises a guiding member and an impacting head, the vertical lift mechanism comprises a vertical lift driving unit, a lifting and moving part, a supporting seat and the like, the lifting and moving part is movably connected with the supporting seat, the supporting seat is connected with the body, the impacting mechanism is arranged on the lifting and moving part, the vertical lift driving unit drives the lifting and moving part to vertically move up and down, and the lifting and moving part drives the impacting mechanism to vertically rise and fall. The digger provided by the invention has the advantages of a long service life, a small amount of maintenance, high work efficiency, shortened body length and applicability to a complex usage occasion.

Description

technical field [0001] The invention belongs to the field of machinery, is applicable to the field of excavation, and in particular relates to a method for maintaining the vertical impact of an impact mechanism and a vertical lifting punching excavator implementing the method. Background technique [0002] At present, the lifting mechanism of coal shearer is basically rocker arm type. The higher the lifting height, the longer the rocker arm, which makes the whole machine bulky and complicated. Because the rocker arm is too long, it consumes a lot of power, and the rocker arm must be rigid. Heavy weight increases the waste of resources. [0003] When the power of the power box is transmitted to the roller on the top of the rocker arm, the distance is long, the structure is complicated, and the energy consumption is large, which increases the manufacturing difficulty and failure rate of the equipment. [0004] Some impact head coal shearers also adopt rocker-type lifting mech...
