Abstract

A multifunctional multi-disk saw solves the problems that the drum type machine head coal mining is low in massive carbon forming rate and large in energy dissipation, which is characterized in that: the multifunctional multi-disk saw is used instead of the drum on the original drum type coal mining machine head, consisting of a center tube body (1), a square bar fixing screw (2), an inner end ring (3), an outer end ring (6), a convex part (7), a square bar fixing screw (8), a center tube spiral plate (10) and a tooth holder (11); a sawing disc (5) or an outer sawing disc (9) is perpendicularly arranged on the center tube body (1); the inner side of the sawing disc close to the center tube body (1) is provided with a bumping block (4).

Description

Multi-functional polydisc piece saw

The utility model relates to a kind of multi-functional polydisc piece saw, belongs to coal mine machinery coal excavation apparatus manufacturing technology field, is particularly useful for the lump coal exploitation of fully-mechanized mining working.

The drum-type head that present state-of-the-art coal-winning machine uses, though mechanical output is big, it is fast to produce coal, because the coal cutting method of its drum-type is almost all rolled into the coal dust face to the coal seam, be difficult to be willing to the coal sanction is slit into piece with the people, and power consumption is big.

The purpose of this utility model is can be willing to arbitrarily the coal seam be cut out be slit into the charcoal piece with the people for overcoming a kind of that above-mentioned deficiency designs, and reduces the digging face that produces coal, and improves block coal rate, the multi-functional polydisc piece saw that energy consumption is low.

The utility model is to realize like this, on former drum shearer head, use cylinder instead multi-functional polydisc piece saw, by central tube main body (1), square bar hold-down screw (2), inner end ring (3), outer end ring (6), protuberance (7), square bar outer end hold-down screw (8), central tube spiral plate (10), toothholder (11) is formed, and it is characterized in that being vertically installed with on central tube main body (1) saw disc (5) or outer saw disc (9), locates setting near central tube main body (1) and bumps son (4) in that saw disc is inboard.

Multi-functional polydisc piece saw of the present utility model, be under the effect of coal-winning machine power, center of rotation tube main body (1), the drive saw disc rotates, go deep into the coal seam at random and the saw formula is carried out in the coal seam cut out and to cut, adjust the distance between saw disc and the saw disc, determine the thin and thick in sawing coal seam, to be broken up by the coal seam of sawing and split by bumping son (4) again, form required piece charcoal.

The advantage of multi-functional polydisc piece saw of the present utility model is, rolling coal by the drum-type in past uses polydisc piece saw instead and the saw formula is carried out in the coal seam cuts out the coal cutting layer, the charcoal block size is cut out the coal cutting layer with the need, the fine coal shape that has reduced the coal seam destroys, improved the block coal rate that work plane is mined, also, reduced energy consumption, greatly improved the economic benefit in colliery because it is concentrated hard.

Description of drawings

Fig. 1 is multi-functional polydisc piece saw structural representation

Among the figure: 1, central tube main body, 2, the square bar hold-down screw, 3, the inner end ring, 4, bump son, 5, saw disc, 6, outer end ring, 7, protuberance, 8, square bar outer end hold-down screw, 9, outer saw disc, 10, the central tube spiral plate, 11, toothholder,

Below in conjunction with description of drawings the utility model embodiment, multi-functional as shown in drawings polydisc piece saw, be on former drum shearer drive mechanism basis of invariable, change the cylinder head into multi-functional polydisc piece saw, its method be central tube main body (1) go up vertical fixing have polylith saw disc (5) or outside saw disc (9), adopt square bar, square bar hold-down screw (2) encircles (3) fixedly saw disc inner end with the inner end, outer end ring (6), protuberance (7), square bar, square bar outer end hold-down screw (8) is saw disc outer end saw disc (9) fixedly, can be the polylith saw disc, and the inboard close central tube main body (1) of saw disc is located to be provided with and bumped son (4), central tube spiral plate (10) is arranged on the central tube main body (1), and toothholder (11) is arranged on the square bar between saw disc and the saw disc.

Claims

1, a kind of multi-functional polydisc piece saw is by central tube main body (1), square bar hold-down screw (2), inner end ring (3), outer end ring (6), protuberance (7), square bar outer end hold-down screw (8), central tube spiral plate (10), toothholder (11) is formed, it is characterized in that on central tube main body (1), being vertically installed with saw disc (5) or outside saw disc (9).

2, multi-functional polydisc piece saw according to claim 1, its feature are that also locating setting in the inboard close central tube main body (1) of saw disc bumps son (4).
