Abstract

The utility model relates to a scraper conveyor whose main shaft is driven by a motor installed on a machine body through a belt pulley, a belt, a speed reducer, roller chain wheels and a roller chain. The main shaft drives a scraper on a loop chain through a round loop chain, a hanging guide wheel and a concave guide wheel and, particularly, the roller chain wheel is formed by a gear ring through overloading screw bolts and wheel cores. A plurality of reinforced sheets are arranged between the scraper and the loop chain. Compared with the existing scraper conveyors, the utility model has the advantages of long service life and simple maintenance.

Description

Scraper cnveyer

The utility model relates to a kind of slat conveyer, is applicable to powder agglomates shape objects such as carrying coal, cinder and sandstone.

In CN2048058u, disclosed and a kind of worm gear and sprocket wheel have been combined into an axle, the worm case at axle two and adjust a bearing is contained in casing mouth both sides by gib block adjustable bolt, nut and bow plate slat conveyer, it is simple in structure that it is had, cost is low, advantage such as in light weight, but it is yielding and burn the deficiency of motor that it also exists scraper plate, thereby increased maintenance load, reduced its service life.

The purpose of this utility model is the slat conveyer that a kind of easy to maintenance and long service life will be provided.

The utility model is to realize like this, drive main shaft by the motor that is contained on the body by small belt pulley, belt, big belt pulley, retarder, small roller sprocket wheel, roller chain, large roller chain, main shaft is by the annulus sprocket wheel, the scraper plate that hangs on guide wheel and the recessed guide wheel drive loop chain is formed, and particularly the large roller sprocket wheel is formed by connecting by overload bolt and wheel stamen by gear ring.When producing overload, overload bolt will be sheared disconnected, thereby protection motor and other transmission parts are raised the long purpose of life thereby reach easy to maintenance with using.

The utility model also can be realized like this: on the basis of above scheme, will between scraper plate and the loop chain reinforced sheet be housed.Thereby make scraper plate be difficult for stressed modification, further reach easy to maintenance and purpose long service life.

Below by drawings and Examples, describe CONSTRUCTED SPECIFICATION of the present utility model and principle of work thereof in detail.

Accompanying drawing 1 is a front view of the present utility model, and accompanying drawing 2 is birds-eye vieies of accompanying drawing 1, and accompanying drawing 3 is amplification circles of large roller sprocket wheel, and accompanying drawing 4 is amplification circles of scraper plate, and accompanying drawing 5 is birds-eye vieies of accompanying drawing 4.

With reference to accompanying drawing, slat conveyer passes through small belt pulley 13 by 1.5 kilowatt motors 12 that are contained on the body 5, belt 11, big belt pulley 10, retarder 4, small roller sprocket wheel 19, roller chain 18 drives the large roller chain 17 that is formed by connecting by the overload bolt 23 of gear ring 22 by 10 millimeters of 4 φ and wheel stamen 24, large roller chain 17 drives main shaft 16, main shaft 16 is by being contained in the adjustable shaft bearing 14 in two gib blocks 21, through bolt 1, nut 2 and bow plate 3 are contained in the both sides of casing 5 mouths, annulus sprocket wheel 15 on the main shaft 16 is by hanging guide wheel 9 and recessed guide wheel 6 drive loop chains 8, and the scraper plate 7 that band reinforced sheet 20 is housed on the loop chain 8 is formed.

When slat conveyer is used as boiler slag removal, the inboard of the recessed guide wheel 6 of slat conveyer is lain in boiler slag eye place, slat conveyer main shaft 16 1 ends are placed on deslagging stacking place, after motor 12 energized, just can make the loop chain 8 that has scraper plate 7 along the B in the accompanying drawing 1 to constantly rotating, make the slag that enters the recessed guide wheel of slat conveyer 6 places constantly be transported to main shaft 16 1 ends, and the machine that is discharged from pile heap outward.For furnace clinker the big or quantity of slag more for a long time, scraper plate 7 is not because the support of reinforced sheet 25 can produce modification; , the quantity of slag excessive when furnace clinker is too many or when being stuck, and the overload bolt 23 that 4 φ 10 millimeters will be sheared disconnected, thereby plays the effect of protection motor and transmission parts.As long as get rid of the overload factor, change the normal operation that the bolt of being cut off can recover slat conveyer simultaneously.

Use drag conveyor described in the utility model, compare with existing drag conveyor, have easy to maintenance and advantage long service life.
