Description
Technical field
The utility model relates to colliery used on down-hole mining surface coal-winning machine device, relates in particular to a kind of combining and adopts type coal mining knife system.
Background technology
Under prior art condition, the comprehensive form of adopting under coal mine, substantially be two kinds of performing comprehensive coal mining forms of drilling type coal-winning machine and cutting type coal-winning machine, adopt the performing comprehensive coal mining equipment of drilling type, the performing comprehensive coal mining that carries out large face is feasible, because the efficiency of this coal mining form is high, but for the face of developed surface deficiency, this coal excavation apparatus has no idea to launch, especially adopt the coal mining form of this large developed surface, due to loosening to comprehensively creeping into globality of coal seam, be easy to the incidents that caves in.The sawing formula coal excavation apparatus of prior art, is to cut out digging border at face with the form of sawing, adopts the good stability of this digging form, but relative inefficiency.
Utility model content
The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of combining to adopt type coal mining knife system, the form combining with drilling type performing comprehensive coal mining and cutting type performing comprehensive coal mining, guaranteeing to tunnel under safe prerequisite, improving the efficiency of colliery down-hole mining.
One described in the utility model is combined and is adopted type coal mining knife system, include left coal cutting cutter, cutter use hole for water spraying, cutter with in hole for water spraying, coal cutting dish, dish hole for water spraying, right coal cutting cutter and the lower hole for water spraying of cutter.Said coal cutting dish, roughly the same with the disk coal cutting device of prior art, consider environment for use of the present utility model, said coal cutting dish should be slightly less than commercially available disk coal cutting device now, in the middle position of said coal cutting dish, be provided with dish hole for water spraying, simultaneously directly over coal cutting dish, under, position in the dish of front-left and front-right, be also provided with dish hole for water spraying.In the left side of coal cutting dish, be provided with left coal cutting cutter, be provided with right coal cutting cutter on the right side of coal cutting dish, in the middle position of left coal cutting cutter and right coal cutting cutter, be provided with hole for water spraying in cutter use, position in the upper end of left coal cutting cutter and right coal cutting cutter, is provided with cutter and uses hole for water spraying, position in the lower end of left coal cutting cutter and right coal cutting cutter, is provided with the lower hole for water spraying of cutter.In the scope of operation of said coal cutting dish, be provided with cutting diamond cutter, creeping into coal cutting dish of the form that specifically arranges of diamond cutter and prior art is roughly the same.Said left coal cutting cutter and right coal cutting cutter are arranged on face left two coal cutting dishes of same form on side and right side of coal cutting, and the structure of the general structure of coal cutting dish and the chain saw of prior art is roughly the same, and just sawtooth is larger.A kind of structure that the coal cutting cutter of adopting the coal cutting dish of type coal mining knife system and be arranged on the coal cutting dish left and right sides adopts same engine to drive of combining described in the utility model, use same motor to connect Driven by Coaxial device, drive in the lump coal cutting dish and the coal cutting cutter that is arranged on coal cutting dish both sides.
One described in the utility model is combined and is adopted type coal mining knife system, and overall structure is simple, easy for operation, good stability, and reliability is high.Use one described in the utility model to combine and adopt type coal mining knife system, the form combining with drilling type performing comprehensive coal mining and cutting type performing comprehensive coal mining, is guaranteeing to tunnel under safe prerequisite, improves the efficiency of colliery down-hole mining.A kind of face driving coal mining activity of adopting type coal mining knife system and being especially suitable for middle and small scale coal mine of combining described in the utility model, less on the impact of coal seam environment in operation process, so safety is better.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of adopting type coal mining knife system of combining described in the utility model.1-left coal cutting cutter, 2-cutter is used the lower hole for water spraying of hole for water spraying 4-coal cutting dish 5-hole for water spraying 6 for dish-right coal cutting cutter 7-cutter in hole for water spraying 3-cutter use.
Detailed description of the invention
Be described as follows referring now to accompanying drawing 1: one described in the utility model is combined and adopted type coal mining knife system in conjunction with the embodiments, include left coal cutting cutter 1, cutter use hole for water spraying 2, cutter with in hole for water spraying 3, coal cutting dish 4, dish hole for water spraying 5, right coal cutting cutter 6 and lower hole for water spraying 7 for cutter.Said coal cutting dish 4, roughly the same with the disk coal cutting device of prior art, consider environment for use of the present utility model, said coal cutting dish 4 should be slightly less than commercially available disk coal cutting device now, in the middle position of said coal cutting dish 4, be provided with dish with hole for water spraying 5, simultaneously directly over coal cutting dish 4, under, position in the dish of front-left and front-right, be also provided with dish hole for water spraying 5.In the left side of coal cutting dish 4, be provided with left coal cutting cutter 1, be provided with right coal cutting cutter 6 on the right side of coal cutting dish 4, in the middle position of left coal cutting cutter 1 and right coal cutting cutter 6, be provided with hole for water spraying 3 in cutter use, position in the upper end of left coal cutting cutter 1 and right coal cutting cutter 6, is provided with cutter and uses hole for water spraying 2, position in the lower end of left coal cutting cutter 1 and right coal cutting cutter 6, is provided with lower hole for water spraying 7 for cutter.In the scope of operation of said coal cutting dish 4, be provided with cutting diamond cutter, creeping into coal cutting dish of the form that specifically arranges of diamond cutter and prior art is roughly the same.Said left coal cutting cutter 1 and right coal cutting cutter 6 are arranged on two coal cutting dishes of the same form on coal cutting dish 4 left sides and right side, and the structure of the general structure of coal cutting dish and the chain saw of prior art is roughly the same, and just sawtooth is larger.A kind of structure that the coal cutting cutter adopting the coal cutting dish 4 of type coal mining knife system and be arranged on coal cutting dish 4 left and right sides adopts same engine to drive of combining described in the utility model, use same motor to connect Driven by Coaxial device, drive in the lump coal cutting dish 4 and the coal cutting cutter that is arranged on coal cutting dish 4 both sides.One described in the utility model is combined and is adopted type coal mining knife system, and overall structure is simple, easy for operation, good stability, and reliability is high.Use one described in the utility model to combine and adopt type coal mining knife system, the form combining with drilling type performing comprehensive coal mining and cutting type performing comprehensive coal mining, is guaranteeing to tunnel under safe prerequisite, improves the efficiency of colliery down-hole mining.A kind of face driving coal mining activity of adopting type coal mining knife system and being especially suitable for middle and small scale coal mine of combining described in the utility model, less on the impact of coal seam environment in operation process, so safety is better.
