Abstract
The utility model relates to a component of an underground coal mine conveying device, specifically to a mass flow longitudinal high-position coal drop cushioning device. The cushioning device solves the problems of the prior art that the overlapping part between a rubber belt conveyor and a trench has a big drop height and a too high coal flow dropping speed. The utility model comprises a bottom beam holding frame. The bottom beam holding frame front side opposed to the machine head is provided with a coal stopping plate. The two sides of the bottom beam holding frame are provided with side protective plates. And a coal receiving winnowing-pan is provided on the lower end of the bottom beam holding frame. The utility model can make a high-speed coal flow directly impact on the baffle plate of the coal receiving device. Then a coal flow piling area is formed in the delta area of the baffle plate. The coal in the coal flow piling area then falls to the coal receiving winnowing-pan below. The coal on the coal receiving winnowing-pan then flows downstream into the trench. The coal flow which experiences three smooth transfers has a reduced coal flow impact and an improved coal block ratio.
Description
Technical field
The utility model relates to the coal conveyer assembly under a kind of coal mine, is specially the vertical high-order coal breakage coal stream shock absorber of a kind of big flow.
Background technology
For solving main fortune and auxilliary fortune contradiction, main fortune and the auxilliary crunode place that delivers at some mines adopt 1.4 rice glue band conveyers and trench to slip this design of overlap joint to guarantee the unimpeded of main fortune and auxilliary transport line road, shown in (figure one) through regular meeting.And travelling apron and trench slip the transfer point place owing to band machine belt speed fast (3.5m/s), big, the drop big (3.7m) of coal amount, cause the loss of coal pieces rate and charcoal piece to spill casualty accident easily.It is unrealistic again under this reprinting discrepancy in elevation large-scale plants such as spiral chute, feeder to be installed, and so is badly in need of manufacturing and designing the special device for coal that connects of a cover to address this problem.
Summary of the invention
The utility model slips in order to solve the travelling apron that exists in the prior art and trench that lap-joint's drop is big, coal stream splashes down the too fast problem of speed, and provides a kind of big flow vertical high-order coal breakage coal stream shock absorber.
The utility model is realized by following technical scheme, the vertical high-order coal breakage coal stream shock absorber of a kind of big flow, comprise the collet roof beam structure, the collet roof beam structure is that spillplate, dual-side are provided with side guard plate, also are provided with in the lower end of collet roof beam structure and connect the coal dustpan facing to the front side of head.
Spillplate comprises upper supporting leg, following supporting leg, is fixed with baffle plate on upper supporting leg, the baffle plate outside is fixed with oblique supporting leg.The baffle plate inboard is added with triangle muscle, coal guide plate.
Baffle plate is positioned at the unloading roller dead ahead to be formed by two, is used to connect coal.The baffle plate inboard is added with three road triangle muscle to strengthen intensity, and while and coal guide plate are avoided coal stream directly to pound and hit the spillplate body in conjunction with forming coal stream stocking angle.Baffle plate flow guiding inclined plate angle is 30 ° and is used for secondary and reprints to connecing the coal dustpan in the lateral plan.Upper supporting leg, following supporting leg, oblique supporting leg are used for the fixing of plate washer.
Totally two both sides that are positioned at spillplate of side guard plate is separately fixed on the upper supporting leg and bottom joist of spillplate, makes to connect device for coal and form an obturator, mainly act as to prevent that the charcoal piece from spilling and hurt sb.'s feelings.
Connecing coal dustpan size is to design according to head width and discharge height, its act as connect clearly with device the coal reprinted of clear ground coal and spillplate flow guiding inclined plate secondary slip to trench to guarantee that coal stream can fully smoothly be reprinted.Connect coal dustpan rear end and be hung on the sealing-tape machine head fixed beam with steel rope, front end is fixed on the bottom joist, and setting angle becomes 35 ° with ground, to connect coal dustpan front end downside and is welded with a block plate and is used for being connected with bottom joist in last punching in order to be fixed on.And be reserved with the lengthening that two rounds are used to connect the coal dustpan connecing coal dustpan front end.
Because of sealing-tape machine the place ahead is a trench, spillplate, side guard plate, connect the coal dustpan and can not be fixed on the roadway floor, adopt the joist form to fix only.The two ends land used of joist is anchored on the base plate, middle be welded with following supporting leg, oblique supporting leg, connect the collet that the coal dustpan matches at diverse location, is used for spillplate, side guard plate, connects the coal dustpan and install and fix.Bottom joist has upper, middle and lower three roads to constitute the collet roof beam structure jointly, first road is used to connect the fixing of coal dustpan and side guard plate, at two collets of both sides welding, on box out and be used for side guard plate and install and fix, middle part face down bonding elongate steel sheet, angle become 55 ° to be used to connect the coal dustpan and to install and fix with I-beam section.Second road is divided into two sections (former because improved the coal amount, prevent chute blockage) and is used for installing and fixing of supporting leg under the spillplate, is welded with two collets on it.The 3rd road is used for installing and fixing of the oblique supporting leg of spillplate, is welded with four collets on it.In order to ensure the installing space of three road joists, four installing and locating beams have been manufactured respectively to guarantee setting accuracy according to calculated length.
The utlity model has following advantage:
(1) adopts three grades of coal breakage modes, slowed down of the impact of direct coal breakage, improved former coal cinder rate greatly lump coal.(2) fully use spatial altitude, adopt directly retaining coal mode, reduced vertical coal breakage distance of high drop, realized the direct overlap joint of two transportation devices.(3) the closure design has prevented that effectively the charcoal piece from spilling casualty accident, has also reduced clear coal work capacity simultaneously, concentrates depositing dust in this device, and dust-laying effect is remarkable, has significantly reduced the tunnel Dust Capacity.(4) universal performance is good, can realize the fixed mode of this type of transloading mode.(5) flexible design is convenient to regulate, and installs and fixes.(6) simple in structure, be convenient to make, install.(7) sturdy and durable, elegant in appearance, good airproof performance.Extendability is strong, leaves the vertical and horizontal extending bore.
