Description

Mine quarrying machine

Technical field

The utility model relates to a kind of quarrying machine, is mainly used in the cutting exploitation of mine stones.

Background technology

The method of perforating explosion is generally taked in the mine stones exploitation, and its advantage is time saving and energy saving.But the major defect of this way is: the working environment poor stability, the stone material systematicness is poor, utilization rate is low, waste is serious.

And existing stone material cutting equipment is owing to existing following defective not to be suitable for the cutting exploitation of mine stones.The first, generally adopt monolithic construction, transportation inconvenience; The second, the decline cutting power of cast-cutting saw slice generally adopts hydraulic way to provide, and hydraulic mechanism can cause saw blade, cutter head damage or cause potential safety hazard because of fatigue produces from falling problem after using a period of time; Three, because the stroke up and down of saw blade is generally shorter, reach bigger depth of cut and just must in the middle of cutting process, the small-sized saw blade be replaced by big specification saw blade, not only waste time and energy, and work efficiency is lower; Four, general saw blade does not have horizontal movement, but needs mobile stone material.

The utility model content

Technical problem to be solved in the utility model is, a kind of new mine quarrying machine is provided, and makes its cutting that is adapted to mine stones exploitation by improving cutting mode.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of mine quarrying machine comprises column, the crossbeam that is slidingly connected with column and be installed in saw blade on the crossbeam by the saw blade main shaft, and it is characterized in that: column has four, is divided into two on two in left side and right side, and their bottom all is fixed on the walking chassis; The upper end of four leading screws is connected by four spindle motors of four leading screw reducers with the column upper end respectively; The lower end of leading screw is installed in column lower end by Bearning mechanism or is installed on the walking chassis; Between two root posts of left side, crossbeam is installed, between two root posts of right side, another crossbeam is installed; The two ends of crossbeam are fixed on the screw that is connected with leading screw by slide plate respectively; Cutting motor and the saw blade main shaft that has saw blade are installed on the crossbeam, are in transmission connection between cutting motor and the saw blade main shaft; Wheeled walking axle is installed below the walking chassis; Be fixed with driving wheel on the walking axle, the latter and movable motor are in transmission connection.

Side on the walking chassis is equipped with hydraulic jack.

Also comprise blade shroud, on crossbeam or blade shroud, sparge pipe is installed.

Also comprise a crane column, its lower end is movably arranged on the walking center chassis position by Bearning mechanism, and the upper end also is connected with Bearning mechanism and by the connecting shackle of cranking arm, and is equipped with on cranking arm and bends and stretches oil cylinder.

The utlity model has following good effect: in the rotation of (1), saw blade, incision stone material certain size, complete machine walking cutting certain distance; More deep again incision stone material certain size, complete machine returns walking; And so forth, until the cutting exploitation that reaches the monoblock stone material; Because use lead screw transmission, stroke is enough big up and down, can the big saw blade of disposable installation, needn't change great film in the cutting, work efficiency is improved.(2), realized the complete machine walking, needn't mobile stone material, be more suitable for mining.(3), each critical piece adopts reassembling type, is convenient to accumulating.(4), adopt the leading screw lifting, its rising or falling speed, amplitude are accurate, safety is good, the saw blade long service life.(5), parts such as the saw blade for heaviness, column, crossbeam, can be by its small crane lifting, operation is very easy.
