Abstract
The invention provides an adjustable screening middle trough, and relates to a middle trough of a scraper conveyer for raw coal screening. According to the conventional middle trough of the scraper conveyer for raw coal screening, the aperture of a middle plate cannot be adjusted according to the requirement, and normal operation of the scraper conveyer cannot be realized due to coal accumulation. According to the adjustable screening middle trough, the lower surface the middle plate is provided with a movable plate with holes, the control for screening the aperture of the middle plate of the middle trough is realized via the adjustment of the relative position of the two plates until the holes of the middle plate are fully covered, the stopping of raw coal screening of the screening middle trough is realized, and the problem of coal accumulation at the bottom of the middle trough of the scraper conveyer is solved. According to the adjustable screening middle trough, the aperture can be flexibly adjusted, the time is saved, the production cost is lowered, and the work efficiency is improved.
Description
Technical field
The present invention relates to the intermediate channel of slat conveyer, be specifically related to the intermediate channel of the slat conveyer of raw coal screening.
Background technology
The intermediate channel of the slat conveyer of current raw coal screening uses a kind of structure of intermediate channel tabularium hole, and middle panel aperture is fixed value, panel aperture size in cannot realizing in screening process regulating as required; Often occur in operational process that coal is accumulated to bottom the middle pan of scraper conveyor, affects the normal operation of slat conveyer, reduce production efficiency.
Summary of the invention
Instant invention overcomes above-mentioned the deficiencies in the prior art part and a kind of adjustable screening intermediate channel is provided.
It is adjustable that a kind of adjustable screening intermediate channel achieves panel aperture size in screening intermediate channel.
Solve the problem that the middle pan of scraper conveyor bottom coal is piled up on the other hand.
The concrete technical scheme that the present invention takes is as follows:
A kind of adjustable screening intermediate channel, comprises intermediate channel both sides ledge 9, middle plate 7, the portable plate 6 that the lower surface also comprising middle plate 7 one piece of arranging is with holes, and the two ends place of portable plate 6 both sides is respectively arranged with back plate 4.
On above-mentioned portable plate 6, the arrangement in hole is consistent with middle plate 7 with aperture.
The two ends of above-mentioned intermediate channel both sides ledge 9 have elongated hole 8, and elongated hole 8 place is provided with guide plate 5, guide plate 5 has long guiding hole 10; Back plate 4 is fixedly connected with by bolt, nut 3 with guide plate 5.
The guide plate 5 of same one end of above-mentioned intermediate channel ledge 9 both sides is other is provided with bearing 2, bearing 2 is equipped with screw rod 1.
The present invention is a kind of adjustable screening intermediate channel, initial active plate 6 coincides with the position in hole on middle plate 7, promote back plate 4 by regulating the screw rod 1 on bearing 2 to move under the common restriction of bolt, nut 3 and long guiding hole 10, back plate 4 drive portable plate 6 relative in plate 7 is parallel longitudinal moves, change the aperture of screening, achieve the adjustment in screening intermediate channel aperture.
When portable plate 6 relative in plate 7 is parallel longitudinal move the distance in an aperture time, by the hole of middle plate 7 cover, realize screening intermediate channel stop raw coal screening, solve the middle pan of scraper conveyor bottom coal pile up problem.
The invention has the beneficial effects as follows: screening intermediate channel aperture is adjustable, flexibly easy to adjust, saves time, reduces productive costs, increase work efficiency.

Wherein: 1, screw rod, 2, bearing, 3, bolt, nut, 4, back plate, 5, guide plate, 6, portable plate, 7, middle plate, 8, elongated hole, 9, ledge, 10, long guiding hole.
Detailed description of the invention
Describe performance of the present invention in detail below in conjunction with accompanying drawing, but they do not form limitation of the invention.
A kind of adjustable screening intermediate channel, comprises intermediate channel both sides ledge 9, middle plate 7, one piece of portable plate 6 that the lower surface also comprising middle plate 7 is arranged, and the aperture of portable plate 6 is identical with middle plate 7; The two ends place of portable plate 6 both sides is respectively arranged with back plate 4, and portable plate 6 and back plate 4 are welded into one.
The two ends of intermediate channel both sides ledge 9 have elongated hole 8, and elongated hole 8 place is provided with guide plate 5, guide plate 5 has long guiding hole 10, and wherein the guide plate 5 of same one end of intermediate channel ledge 9 both sides is other is provided with bearing 2, bearing 2 is equipped with screw rod 1.Back plate 4 is fixedly connected with by bolt, nut 3 with guide plate 5.
A kind of adjustable screening intermediate channel, initial active plate 6 coincides with the position in hole on middle plate 7, promote back plate 4 by regulating the screw rod 1 on bearing 2 to move under the common restriction of bolt, nut 3 and long guiding hole 10, back plate 4 drive portable plate 6 relative in plate 7 is parallel longitudinal moves, change the aperture of screening, achieve the adjustment in screening intermediate channel aperture, when portable plate 6 relative in plate 7 is parallel longitudinal move the distance in an aperture time hole on middle plate 7 is covered, realize screening intermediate channel and stop raw coal screening.
