Description
The present invention relates to a kind of coal-cutting machinery, is the coal mining device that is used for stope under the coal mine.
In the present employed coal-winning machine, the flittings that adopt more, this coal-winning machine is to rotate the cut coal body by the cylinder that has pick, this cut mode often makes the coal breakage overcrushing, lump coal rate is very low, and no matter its mode of traction is chain haulage or chainless haulage simultaneously, not only structure is complicated, and is difficult to adapt in half-edge coal seam.And be used for the coal plough of girdle more, though adopt planing tool planing coal body, not only will be with baroque plane chain and drive unit, and use inconveniently, the scope of application is also narrow, can not satisfy the needs of coal production.
Purpose of the present invention just is to provide a kind of novel coal-winning machine, has cancelled cylinder, and with the mining way that vibration advances, reaches and exploit lump coal more, and can use in half-edge coal seam and girdle; Also simplify the structure of existing coal-winning machine simultaneously, reduced cost, can obtain higher technical economic benefit.
To the effect that this coal-winning machine of the present invention includes the hydraulic pressure cutting means, hydraulic feed device and hydraulic control system.Its hydraulic pressure cutting means mainly contains hydraulic shock head, vibration oil cylinder, hydraulic vibration converter; Its hydraulic feed device mainly contains the oil cylinder of moving one's steps, moving one's steps advances oil cylinder, guiding oil cylinder, adjust high cylinder.The mining way of this coal-winning machine is to promote to realize coal breakage by vibration of hydraulic shock head and the hydraulic feed device that has pick along the work plane direction.
The hydraulic shock head of this coal-winning machine is made up of pick, cutting head, broken muscle, spillplate, pivot pin.Its cutting head is wedge shape, settles 8～30 groups of picks in wedge point working position, can adopt the replaceable pick of in-line body.
The vibration oil cylinder of this coal-winning machine can be installed in coal mining body upper and lower part with 2 two-way cylinders, and the piston rod of its oil cylinder links to each other with the upper and lower part of cutting head respectively.
The guiding oil cylinder of this coal-winning machine can be with 4 push action cylinders, and level is installed in coal mining body both sides.Adjust high cylinder can be 2～4, is divided into 2 groups and is installed in the forward and backward two ends of coal-winning machine respectively.The oil cylinder of moving one's steps can be 2～4 and is divided into two groups, also is installed in the forward and backward two ends of coal-winning machine; Moving one's steps promotes oil cylinder and can be 2～4, is installed in the coal mining underpart, and its move one's steps piston rod that advances oil cylinder and base of the oil cylinder of moving one's steps cut with scissors knot mutually.
The hydraulic shock head of this coal-winning machine can be installed one at coal-winning machine one end and both constitute the single head walking hydraulic impulsive coal cutter, also can respectively install one at the two ends of coal-winning machine and promptly constitute the double end walking hydraulic impulsive coal cutter.
The operating principle of this coal-winning machine is to drive cutterhead by the vibration oil cylinder to impact coal body, make coal body local broken, simultaneously under the promotion of hydraulic feed device, by pick, cutting head and broken muscle certain thickness is had the coal body simple crushing on the scope of freedom after, pack in the transporter by spillplate.Coal-winning machine is to adopt the forward and backward oil cylinder of moving one's steps to the support of top board and base plate with unclamp, and advances the flexible of oil cylinder by moving one's steps and realize advancing or retreating of coal-winning machine.Mine for guaranteeing that coal-winning machine is directed, also installed guiding oil cylinder and adjust high cylinder, can guarantee that cutterhead do not cut top, do not undercut, realize accurately directed coal mining.
The invention has the advantages that and adopt vibration to promote and the new method of broken coal can be saved energy consumption, reduce cost the lump coal rate height.Since simple in structure, easy to operate, applied widely, for the colliery underground mining provides a kind of new-type coal-winning machine.

Further this inventive embodiment is illustrated below in conjunction with accompanying drawing:
With reference to the accompanying drawings 1, in top, the lower horizontal of body (9) two groups 4 vibration oil cylinders (8) are installed, its vibration oil cylinder piston bar (7) end respectively and cutting head (2) upper and lower part be connected.Hydraulic shock head (1) is respectively installed one at the coal-winning machine two ends, constitutes the double end walking hydraulic impulsive coal cutter.Cutting head (2) is wedge shape, has 3 broken muscle to play booster action on it, and spillplate (4) also is housed on cutting head (2).The oil cylinder (11) of moving one's steps places the outside, head and the tail two ends of body (9), and advance oil cylinder piston bar (14) to link to each other with the oil cylinder pin (13) of moving one's steps with moving one's steps by the oil cylinder seat of moving one's steps (12), thereby body (9) can be advanced under the coordination of oil cylinder (15) and the oil cylinder of moving one's steps (11) moving one's steps, move forward and backward, realize feed motion.In body (9) inboard, two ends adjust high cylinder (17) is installed also.
With reference to the accompanying drawings 2, in the both sides of body (9) two groups 4 guiding oil cylinders (23) are installed.In use, guiding oil cylinder (23) can a side can contact with coal nation, and opposite side can contact with the water jacket nation of coal-face drag conveyor, because the action of guiding oil cylinder, the body that sets right (9) advances coal-winning machine in a certain direction.
With reference to the accompanying drawings 3, be installed on the high-pressure oil pump (28) on the coal-winning machine, running under the dragging of motor (26), produce hydraulic oil after hydraulic pressure cuts down group (31), enter centralized Control and cut down group (33), cut down group (33) by manually or automatically operating centralized Control, make the oil cylinder of moving one's steps (11), adjust high cylinder (17), guiding oil cylinder (23) action, simultaneously, hydraulic oil cuts down (33) through centralized Control and enters hydraulic vibration converter (30), make the hydraulic oil that changes with the certain frequency travel direction enter vibration oil cylinder (8), thereby make cutting head (2) produce the vibratory impulse effect of pressing certain frequency, reach vibration and advance the purpose of mining.Accumulator (32) is linked in the hydraulic circuit, can play cushioning effect.
The course of work of this double end hydraulic shock formula coal-winning machine is as follows:
After opening high-pressure oil pump (28), cutting down group (33) by centralized Control holds out against the oil cylinder of moving one's steps (11) or unclamps, opening the control of vibration oil cylinder (7) cuts down, make vibration oil cylinder (7) vibration, then hydraulic shock head (1) vibrates thereupon, and the cutting head (2) that has pick (6) impacts coal body, and under the effect of the propelling oil cylinder (15) of moving one's steps, coal-winning machine is realized the reach feeding, thereby realizes the purpose of back production coal.When operation, can suitably control guiding oil cylinder (23) and adjust high cylinder (17), impel the coal-winning machine normal operation.
