Abstract

The utility model discloses a central dual-chain scraper conveyor which belongs to the technical field of mineral conveying equipment and mainly relates to serial 620 scraper conveyor. The utility model aims to solve the problem that a ring chain of a serial 620 dual-chain scraper conveyor and central single-chain scraper conveyor is easy to fail at a bend site of material channel when driving a material scraper to operate. The technic proposal is that a plurality of transmission gears respectively equipped at two side-by-side neighboring ring chains are equipped at the middle of a head chainwheel (1) and a tail chainwheel (2). Two ring chains corresponding to the transmission gear of the ring chain are wound at the transmission gears of the head and tail chainwheels to form a stepless ring chain. Each material scraper (4) with certain gap is mounted at two ring chains (3) by a horizontal E-shaped bolt (6) and positioned in a material channel (5), keeping vertical to the movement direction of ring chain. The utility model is mainly used for conveying the coal in a mine and suitable for conveying bit material at other mine.

Description

The double center chain slat conveyer

(1) technical field: belong to load transfer device field, mine, relate generally to 620 serial slat conveyer classes.

(2) background technology: the groove width 620 serial slat conveyers that adopt on mine, the colliery have limit double chain conveyor and middle strand slat conveyer at present.The hopper of limit double chain conveyor restricts because of working environment, when the installation of hopper need have certain crooked radian, it is tight that the double-stranded scraper plate in limit will occur when operating in the crooked radian section that radius big outer side chain in the same center of circle draws, the chain that the inner edge radius is little pine occurs and draws, and easy et out of order in this case whenever on the two strands of limit is in addition adorned 1 material scraper plate and need be used a pair of shackle, because it is many with shackle, article two, the loop chain accumulated error is big, two loop chain degrees of tightness occur and differs, and also is prone to fault; In the strand slat conveyer be the needs of fixing scraper plate and pulling force, select for use the loop chain size big, caused sprocket diameter big, cause the frame head and tail size to increase, when the material in the hopper was irregular, fragile equipment caused fault in addition.

(3), summary of the invention:

Technical problem to be solved in the utility model is to eliminate 620 serial limit double chain conveyors when hopper has crooked radian, can make the stressed unanimity of two loop chains as far as possible, removes the shackle of charging scraper plate on the loop chain simultaneously; Single slat conveyer is because of the loop chain size is big in the releasing, and the sprocket diameter that causes increases and fails in the material process because of the irregular fault that causes of material in the hopper.

The technical scheme that solves the problems of the technologies described above is a design double center chain slat conveyer, and it connects the head sprocket wheel by electrical motor through fluid coupling, reductor.Attaching has hopper between head sprocket wheel and the tail sprocket wheel, device has electrodeless the installing around on head sprocket wheel and tail sprocket wheel of loop chain of material scraper plate, it is characterized in that the middle part of head sprocket wheel and tail sprocket wheel is shaped on the driving cog of two loop chains that face mutually side by side, two loop chains that adapt with the driving cog of loop chain install around and form electrodeless loop chain on the driving cogs on head sprocket wheel and the tail sprocket wheel, and each material scraper plate at regular intervals is packed on two loop chains and with the loop chain service direction is perpendicular by horizontal E shape bolt and is seated in the hopper.

The beneficial effects of the utility model: 1, because the driving cog of two loop chains of the present utility model faces the middle part that is located at sprocket wheel side by side mutually, be contained in two loop chains on the chain sprocket drive tooth when moving to the hopper bending radian section is arranged, the double-stranded scraper plate machine in limit can not occur because of the differ fault of appearance of two loop chain degrees of tightness; Also having overcome simultaneously middle strand slat conveyer is that loop chain has enough pulling force and is convenient to the big consequence of frame head and tail chain size of wheel that fixing loop chain size of expecting that scraper plate causes causes greatly, has also eliminated middle strand because of the irregular accident that causes in the conveying of the material in the hopper; 2, owing to adopted horizontal E shape bolt to install the material scraper plate on loop chain, not only quick for installation, the while has also been eliminated a plurality of shackles of having used when feeding scraper plate, make two loop chains consistent on length dimension, the precision height, stressed consistent intensity height during work has improved the quality of this machine greatly; 3, because sprocket wheel and sprocket shaft have adopted splined, one is convenient to install, and transmission force is big simultaneously;

(5) specific embodiment:

Referring to figs. 1 through Fig. 6, connect reductor 9 by electrical motor 7 through fluid coupling 8, this reductor connects head sprocket wheel 1, attaching has hopper 5 between head sprocket wheel 1 and the tail sprocket wheel 2, device has loop chain 3 electrodeless the installing around on head sprocket wheel 1 and tail sprocket wheel 2 of material scraper plate 4, it is characterized in that the head sprocket wheel 1 of excellent suitability for press forming and the middle part of tail sprocket wheel 2 are shaped on the electro-chemical machining shaping, the driving cog of two loop chains that face mutually side by side of flank of tooth quenching strengthening, this driving cog is 7 teeth at five equilibrium sprocket periphery angle, two loop chains 3 that adapt with the driving cog of loop chain install around and form electrodeless loop chain on the driving cogs on head sprocket wheel and the tail sprocket wheel, each material scraper plate 4 at interval 1000mm-1024mm on the loop chain is packed on two loop chains, its fit is on the flat ring of loop chain, to expect scraper plate 4 and perpendicular the tightening together of loop chain operation scheme with horizontal E shape bolt 6, insert in the hopper 5, on the inboard top and bottom of the biside plate of this hopper wear plate 11 is housed.Head sprocket wheel and tail sprocket wheel are to be contained on the bearing seat by 10 of sprocket shafts, and sprocket wheel is a spline fitted with cooperating of sprocket shaft.
