Abstract
The invention discloses the top thorn of a kind of a kind of device that scores a goal reclaimed when pushing up online portion's coal.Including body, 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.Using cone and the structure of chute in the present invention, make cone undertake the function heading into coal seam, chute accommodates shear, not only supports shear, also protects the shear impact from coal breakage.During in the present invention, the cone of body upper part upwards thrusts the mesh of top net, making in twine that the top net groove between two cones, driving means drives shear, is cut off pushing up the twine netted with coordinating of rotating blade by fixing blade.
Description
Technical field
The present invention relates to the device of orcible entry top net during a kind of colliery Sub-Level Caving.
Background technology
At present, the fully-mechanized mining working of colliery commonly used Sub-Level Caving technology, in order to before and after protective stent, head and the tail of drag conveyor are not buried by the stone of inbreak, on the support of work surface two ends, typically lay top net protect.If reclaim the coal resources pushing up online portion, owing to top net is difficult to remove, during the net of manual demolition top, potential safety hazard is very big simultaneously, often can only abandon, and the coal resources so pushing up online face can not reclaim, and causes the significant wastage of resource.Up to the present, yet there are no and reclaim the device appearance of scoring a goal pushing up online portion coal, also have no relevant report.Applicants have invented a kind of shear, due to construction features, shear can not be inserted directly into coal seam, also it is necessary to have basis relies on simultaneously when installing.
Summary of the invention
It is an object of the invention to provide the top thorn of a kind of a kind of device that scores a goal reclaimed when pushing up online portion's coal.
The technical scheme is that and include body, 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.
Using cone and the structure of chute in the present invention, make cone undertake the function heading into coal seam, chute accommodates shear, not only supports shear, also protects the shear impact from coal breakage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the schematic diagram after Fig. 1 loads shear.
Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but does not constitute any limitation of the invention.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 in the head plate of support tail beam flashboard of work surface two ends, it is in line layout with support.When scoring a goal, support plate is made to stretch out, drive body 1 to be raised above and finally head in the mesh of net, make in each twine groove between two adjacent vertebral, after starting driving means 3, making two connecting plates 2 of shear slide in the chute of body, the rotating blade cutter groove from cone side screws out, making shearing motion with fixing blades fit, twine is cut off the most at last.After operation of scoring a goal completes, driving means 3 resets, and makes rotating blade transfer back in cone, and support tailstock plate is retracted, and makes the coal in online portion, top fall from the net place of cutting off, top, reaches to reclaim purpose.
Claims (1)
1. the top thorn of the device that scores a goal, it is characterised in that: including that body (1), described body (1) top are evenly equipped with cone, 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.
