Abstract
The utility model discloses an adjustable screening middle slot, which relates to a middle slot of a scraper conveyer for screening raw coals. Middle slots of existing scraper conveyer for screening the raw coals can not adjust the aperture size of a middle plate according demands and enable coals to stack, thereby being not capable of normally running. A moving plate with a hole is arranged on the lower surface of a middle plate of the adjustable screening middle slot, and the adjustable screening middle slot achieves to control the aperture size of the middle plate of a screening middle slot by adjusting relative positions of two plates until the hole of the middle plate is completely covered, thereby achieving to stop raw coal screening of the screening middle slot, and solving the problem that the coals are stacked on the bottom portion of the middle slot of the scraper conveyer. The adjustable screening middle slot can flexibly adjust aperture, saves time, reduces production cost, and improves work efficiency.
Description
Technical field
The utility model relates to the intermediate channel of slat conveyer, is specifically related to the intermediate channel of the slat conveyer of raw coal screening.
Background technology
What the intermediate channel of the slat conveyer of raw coal screening was used at present is the structure in a kind of intermediate channel tabularium hole, and middle panel aperture is fixed value, cannot realize panel aperture size in adjusting as required in screening process; In operational process, often occur that coal is accumulated to the middle pan of scraper conveyor bottom, affect the normal operation of slat conveyer, reduce production efficiency.
Summary of the invention
The utility model has overcome 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 has realized in screening intermediate channel panel aperture size.
Solved on the other hand the problem that the middle pan of scraper conveyor bottom coal is piled up.
The concrete technical scheme that the utility model is taked is as follows:
An adjustable screening intermediate channel, comprises intermediate channel both sides ledge 9, middle plate 7, also comprises a portable plate with holes 6 of the lower surface setting of middle plate 7, and the place, two ends 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 slotted hole 8, and slotted hole 8 places are provided with guide plate 5, have long guiding hole 10 on guide plate 5; Back plate 4 is fixedly connected with by bolt, nut 3 with guide plate 5.
Guide plate 5 sides of same one end of above-mentioned intermediate channel ledge 9 both sides are provided with bearing 2, and screw rod 1 is housed on bearing 2.
The utility model is a kind of adjustable screening intermediate channel, on initial active plate 6 and middle plate 7, the position in hole coincides, by regulating the screw rod 1 promotion back plate 4 on bearing 2 to move under the common restriction of bolt, nut 3 and long guiding hole 10, back plate 4 drive portable plates 6 relative in plate 7 parallel longitudinals move, change the aperture of screening, realized the adjusting in screening intermediate channel aperture.
When portable plate 6 relative in plate 7 parallel longitudinals while moving the distance in an aperture, the hole of middle plate 7 is covered, realize screening intermediate channel and stop raw coal screening, solved the problem that the middle pan of scraper conveyor bottom coal is piled up.
The beneficial effects of the utility model are: screening intermediate channel aperture is adjustable, easy to adjust flexible, save time, and have reduced productive costs, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of structural representation of the present utility model is to view;
Fig. 3 is structural representation B-B cutaway view of the present utility model.
Wherein: 1, screw rod, 2, bearing, 3, bolt, nut, 4, back plate, 5, guide plate, 6, portable plate, 7, middle plate, 8, slotted hole, 9, ledge, 10, long guiding hole.
The specific embodiment
Below in conjunction with accompanying drawing, describe performance of the present utility model in detail, but they do not form to restriction of the present utility model.
An adjustable screening intermediate channel, comprises intermediate channel both sides ledge 9, middle plate 7, also comprises a portable plate 6 of the lower surface setting of middle plate 7, and the aperture of portable plate 6 is identical with middle plate 7; The place, two ends of portable plate 6 both sides is respectively arranged with back plate 4, and portable plate 6 is welded into one with back plate 4.
The two ends of intermediate channel both sides ledge 9 have slotted hole 8, and slotted hole 8 places are provided with guide plate 5, have long guiding hole 10 on guide plate 5, and wherein the guide plate 5 of same one end of intermediate channel ledge 9 both sides is other is provided with bearing 2, and screw rod 1 is housed on bearing 2.Back plate 4 is fixedly connected with by bolt, nut 3 with guide plate 5.
A kind of adjustable screening intermediate channel, on initial active plate 6 and middle plate 7, the position in hole coincides, by regulating the screw rod 1 promotion back plate 4 on bearing 2 to move under the common restriction of bolt, nut 3 and long guiding hole 10, back plate 4 drive portable plates 6 relative in plate 7 parallel longitudinals move, changed the aperture of screening, realized the adjusting in screening intermediate channel aperture, when portable plate 6 relative in plate 7 parallel longitudinals the hole on middle plate 7 is covered while moving the distance in an aperture, realize screening intermediate channel and stop raw coal screening.
