This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time

Abstract : selective mechanisms exist in organism and biosphere, which select the cells with less dna injuy and reproduces them. there are two models ; mechanisms 1 and mechanisms 2, represented respectively b bacteria and mechanolytes of human beings. cells with mechanisms 1 ( e. g. bacteria, generative cells, cancer cells ) can reproduce infinitely, while somatic cells can not. there are deep - going reasons behind the two categories of selective mechanisms. the canceration of the cells is a degenerating process from mechanisms 2 to mechanisms 1
