Abstract
The utility model relates to a squeegee conveyor for coal mine comprehensive mining working face, which is characterized in that: a dedicated rack-fixed seat is added on the frame of the tail end of the machine near the drag rack-fixed seat on the end of the machine frame, and a dedicated drag rack is provided on the dedicated rack-fixed seat and the drag rack-fixed seat on the end of the machine frame. The utility model can make the coal mining machine shear directly to the tail end of the machine, remaining no coal stack, and without lying at the tail end of the machine. The productive time of every shear of coal can be cut down by 30 minutes more or less, which improves the working efficiency. The daily production capacity is three shears of coal more than the former production of the drag conveyor before reconstruction and the coal more produced in the same time(one working face is one day) can be converted into improved performance of about 480, 000 yuan. On the other hand, the utility model widely reduces the labor intensity of the operating staff working at the tail end of the machine, and eliminates the safety threat of lying at the tail end of the machine.
Description
Technical field
The utility model relates to a kind of slat conveyer, specifically the coal mine fully-mechanized mining working slat conveyer.
Background technology
At present, all there is a common defective in the slat conveyer that coal-face uses, i.e. coalcutter coal cutting is cut less than tail, stays dump.The slat conveyer tail pushes away to pass by, and must take manually to crouch tail, could shift the slat conveyer tail onto coal nation.The each coal cutting of coalcutter carries out once manually crouching tail behind tail, increased working strength of workers.What is more important coal machine cut coal causes that tail trigonum top board is loosening, although top board is in time strengthened management, there is very big security threat in personnel's tail thereunder for sleeping at random.And must stop coal cutting during tail for sleeping in, the tail that crouches approximately needs 30-40 minute, has reduced production efficiency.
Summary of the invention
The purpose of this utility model is: provide a kind of and set up traction rack mechanism at tail, make the coalcutter coal cutting directly to the coal mine fully-mechanized mining working slat conveyer of tail.
Realize that foregoing invention purpose technical scheme is such:
The coal mine fully-mechanized mining working slat conveyer comprises electrical motor, reductor, frame, aircraft tail shelf, sprocket wheel, chain, ramp plate, scraper plate, traction rack permanent seat and traction rack, it is characterized in that:
On aircraft tail shelf, set up a special-purpose tooth bar permanent seat, on the traction rack permanent seat of special-purpose tooth bar permanent seat and frame end, be provided with a special-purpose traction rack with the traction rack permanent seat adjacent of frame end; Described special-purpose tooth bar permanent seat is identical with the traction rack fixed seat structure; Described special-purpose traction rack is identical with the traction rack structure.
The attachment face of described special-purpose tooth bar permanent seat is provided with connecting panel.
The utility model is set up traction rack mechanism at the slat conveyer tail, make the coalcutter coal cutting directly arrive tail, do not stay dump, do not need the tail that crouches, save every cutter coal production time about 30 minutes, improved work efficiency, the productive output of every day is compared and can be produced 3 cutter coals more with transforming the front scrapping plate conveyer, is about 480,000 yuan by the voluminous coal conversion increase benefit of (driving surface one day in) in the identical time.Alleviate tail operating personnel's labour intensity on the other hand greatly, eliminated the security threat that is subjected to because of the tail that crouches.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is special-purpose tooth bar permanent seat scheme drawing,
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
See Fig. 1, coal mine fully-mechanized mining working comprises electrical motor 6, reductor 11, frame, aircraft tail shelf 2, sprocket wheel 5, chain 4, ramp plate 1, scraper plate 3, traction rack permanent seat 8 and traction rack 7 with slat conveyer.
On aircraft tail shelf 2, fixedly mount a special-purpose tooth bar permanent seat 10 with traction rack permanent seat 8 adjacents of frame end, fixed installation one special-purpose traction rack 9 on the traction rack permanent seat 8 of special-purpose tooth bar permanent seat 10 and frame end; Special-purpose tooth bar permanent seat 10 is identical with traction rack permanent seat 8 structures; Special-purpose traction rack 9 is identical with traction rack 7 structures; Be fixed with connecting panel 12 on the attachment face of special-purpose tooth bar permanent seat 10, see Fig. 2, Fig. 3.
When being used for the on-the-spot transformation in down-hole, can special-purpose tooth bar permanent seat 10 be fixedly installed on the aircraft tail shelf 2 by screw on special-purpose tooth bar permanent seat 10 base plates and bolt.
Before slat conveyer is not gone into the well installation, can special-purpose tooth bar permanent seat be fixedly installed on the aircraft tail shelf 2 by welding manner.
Claims (2)
