Abstract
The invention discloses a novel tool structure of a vertical shaft drill, and is characterized in that multi-blade hobs are arranged on the end face of a cutting plate body, spiral size scrapers are arranged on the end face of the cutting plate body, each of the multi-blade hobs is located in a region between the scrapers, a spiral convergence center of the size scraper is provided with a slag outlet, and the upper side of the slag outlet is communicated with a sipper. According to the invention, by adopting the multi-blade hobs, the pressure acted on the rock is larger so as to be beneficial for cutting the rock, and the cutting efficiency is improved; the size is collected through the curved slurry collecting scrapers, so that the slag soil is quickly transported, and the working efficiency is improved.
Description
technical field
The invention belongs to shaft excavation technical field, relate in particular to a kind of Novel silo cutting tool for drill structure.
Background technology
Vertical shaft drilling equipment has a large amount of uses in colliery and mine at present, but the restriction due to geological conditions, its use is subject to great restriction, major limitation has two aspects, the first, referring to Fig. 4, use rolling hobbing cutter efficiency very low, by friction, carry out rock cutting running into rock, this method only has the progress of tens meters for general one month; The second, because disk body size is very large, by the rolling hobbing cutter rock getting off that weares and teares, can not collect in time slag outlet, to such an extent as to quarrel soil cannot transport outward fast, caused efficiency of construction low.
Summary of the invention
The present invention is directed to problems of the prior art and deficiency, a kind of cutting rock that is conducive to is provided, improve cutting efficiency, and can improve the quarrel soil Novel silo cutting tool for drill structure of outward transport fast.
Technical scheme: a kind of Novel silo cutting tool for drill structure, comprise cutting disk body, disk body rotating shaft is installed on cutting center, the disk body back side, on cutting disk body end face, be provided with hobboing cutter, on cutting disk body end face, be provided with spiral-shaped slurries scraper plate, in the region of each hobboing cutter between scraper plate, the spiral convergence center of slurries scraper plate is provided with slag notch, slag notch is positioned at cutting disk body spindle central, the upside of slag notch is communicated with pulp-absorbing pipe, pulp-absorbing pipe is arranged in cutting disc rotating shaft inner chamber, cutting disk body rotating shaft and drive unit are in transmission connection, pulp-absorbing pipe is communicated with the midge pump housing.
Described hobboing cutter is multi-edge type hobboing cutter, in hobboing cutter rotating shaft, by bearing, broach shell is installed, and is set with side by side the blade of a plurality of plate-likes on broach shell, forms combined type multi-edge type hobboing cutter.
The diameter of each blade of described multi-edge type hobboing cutter is identical, or the diameter of adjacent knife blades blade diameters different and separately are identical.
Described spiral-shaped slurries scraper plate is one or two, and described slag notch is one or two.
Beneficial effect: 1, cutting disk body center is provided with pulp-absorbing pipe, cutting disk body end face is provided with spiral slurries scraper plate, by disk body back side reperfusion serosity, cutting disk body is in rotary course, the slurries at the disk body back side enter disk body work plane downwards from circumferential edges, rely on the midge pump housing by pulp-absorbing pipe, the slurries in work plane region to be extracted out from disk body center, disk body is rotated in the forward and can drives slurries reverse rotation, slurries carry rock slag and counter-rotate together and converge at slag notch, the rock slag of guaranteeing to wear and tear can be transported outward fast in time, has improved operating efficiency.
2, adopt multi-edge type hobboing cutter, the pressure acting on like this above rock is larger, is conducive to cutting rock, improves cutting efficiency.
accompanying drawing explanation:
Fig. 1 is cutting disc body running view of the present invention;
Fig. 2 is the end face structure schematic diagram that cuts disk body in Fig. 1;

Number in the figure: 1 is cutting disk body, and 2 is multi-edge type hobboing cutter, and 3 is spiral-shaped slurries scraper plate, and 4 is pulp-absorbing pipe, and 5 is slurries, 6 is slag notch, and 7 is borehole wall, and 8 is pedestal, and 9 is hobboing cutter rotating shaft, 10 is bearing, and 11 is broach shell, and 12 is each blade of multi-edge type hobboing cutter, 13 knife faces that are rolling hobbing cutter; 14 is cutting disk body direction of rotation, and 15 is slurries flow direction.
The specific embodiment
Embodiment 1: referring to Fig. 1, Novel silo cutting tool for drill structure is to be set with pulp-absorbing pipe 4 in the rotating shaft of cutting disk body 1 (being demonstration in figure) inner chamber.Referring to Fig. 2, on cutting disk body 1 end face, be provided with two centrosymmetric spiral-shaped slurries scraper plates 3, in the region of each hobboing cutter between scraper plate.Described hobboing cutter is multi-edge type hobboing cutter 2, referring to Fig. 3, in the rotating shaft 9 of multi-edge type hobboing cutter, by bearing 10, broach shell 11 is installed, on broach shell 11, be set with side by side the blade 12 of a plurality of plate-likes, form combined type multi-edge type hobboing cutter 2, wherein the diameter of each blade of multi-edge type hobboing cutter 2 is identical.
The spiral convergence center of slurries scraper plate 3 is provided with one or two slag notch 6, and two slag notches 6 in Fig. 2 lay respectively at cutting disk body spindle central position, and lays respectively at the end of two slurries scraper plates 3.The upside of slag notch 6 is communicated with pulp-absorbing pipe 4, and rotating shaft and the drive unit of cutting disk body 1 are in transmission connection, and pulp-absorbing pipe 4 is communicated with the midge pump housing.
Embodiment 2, and accompanying drawing is not drawn, and content is substantially the same manner as Example 1, and something in common does not repeat, different: the diameter blade diameters different and separately of adjacent knife blades are identical.
