Abstract
The utility model discloses a top thorn of device scores a goal when retrieving the online portion's coal in top. Which comprises a body, body upper portion equipartition has the cone, and the bottom is equipped with the spout, and this spout top is equipped with the sword groove, and this sword groove upwards extends to in the cone on upper portion. The utility model discloses the structure of well adoption cone and spout makes the cone undertake a function of going into the coal seam, and the spout holds shearing mechanism, has not only supported shearing mechanism, has still protected shearing mechanism to avoid the impact of coal breakage. The utility model discloses the cone on well body upper portion makes the twine of top net be arranged in the slot between two cones in upwards pierceing the mesh of a net, and drive arrangement drive shearing mechanism, will push up the twine of net through fixed blade and spinning blade's cooperation and cut.
Description
Technical field
The utility model tears down the device of top net when relating to a kind of colliery Sub-Level Caving.
Background technology
At present, colliery generally adopts the fully-mechanized mining working of Sub-Level Caving technology, in order to the head of drag conveyor before and after protective stent and tail are not buried by the stone of inbreak, on the support of working face two ends, generally lays top net protect.If when reclaiming the coal resources pushing up online portion, because top net not easily removes, during the net of manual demolition top, potential safety hazard is very large simultaneously, often can only abandon, and the coal resources pushing up online face like this can not reclaim, and cause the significant wastage of resource.Up to the present, yet there are no the device that scores a goal reclaiming online portion, top coal and occur, also have no relevant report.Applicants have invented a kind of shear, due to design feature, shear directly can not insert coal seam, and basis also must be had when installing to rely on simultaneously.
Summary of the invention
The purpose of this utility model be to provide a kind of reclaim top online portion's coal time a kind of device that scores a goal top thorn.
The technical solution of the utility model is: comprise body, and described body upper part is evenly equipped with cone, and bottom is provided with chute, and this chute top is provided with cutter groove, and this cutter groove extends up in the cone on top.
Adopt the structure of cone and chute in the utility model, cone is born head into the function in coal seam, chute holds shear, not only supports shear, also protects the impact of shear from coal breakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram after Fig. 1 loads shear.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but does not form any restriction of the present utility model.Shown in Fig. 1, the top of body 1 is evenly equipped with cone, and bottom is provided with chute, and this chute top is provided with cutter groove, and this cutter groove extends up in cone.
During work: body 1 is fixed by bolts on the head plate of the support tail beam flashboard of working face two ends, is in line with support and arranges.When scoring a goal, support plate is stretched out, drive body 1 upwards to rise and finally head in the mesh of net, make in the groove of each twine between two adjacent vertebral, after starting drive unit 3, two connecting plates 2 of shear are slided in the chute of body, and rotating blade screws out from the cutter groove of cone side, coordinate with fixed blade and make shearing motion, twine is cut off the most at last.After operation of scoring a goal completes, drive unit 3 resets, and makes rotating blade transfer back in cone, and support tailstock plate is retracted, and makes the coal in online portion, top cut off whereabouts from top net, reaches recovery object.
