Description
Technical field
The utility model relates to a kind of Transport Machinery, relates in particular to a kind of shaft type conveyor screw.
Background technology
Domestic existing at present " GX serial universal conveyor screw (the F200-F400 scope) " of listing national standard in.GX serial universal conveyor screw (F200-F400) is domestic application one of airtight continuous conveyor of bulk granular material the most widely; Form by parts such as driving device (not shown), drop-hanger bearing body 31, screw shaft 32, side bearing (not shown), casings 33, referring to Fig. 1.Wherein screw shaft 32 is to be formed by connecting according to conveyor lengths and through flange 34 segmentations, wherein between flange 34 junctions rely on drop-hanger bearing body 31 supportings be suspended on the casing 33.
But; The first, owing to flight being interrupted on the screw shaft 32 at drop-hanger bearing body 31 places; Lost the thrust that flight applies at this in the logistics course of conveying, formed delay, just will be detained material 35 and pass forward owing to follow-up constantly defeated next logistics extruding.More, material 35 is piled up gradually, formed bigger delay band because the operational throughput of drop-hanger bearing body 31 both sides can't be reached balance, as shown in Figure 1.The second, because the existence of drop-hanger bearing body 31 has reduced the defeated material of actv. cross-sectional plane greatly, also make the materials flow that is certain cross-sectional plane be obstructed at drop-hanger bearing body place and pile up, increased near the thrust that flight bore before this bearing body thereupon.
The development of both of these case has just formed the material obstruction.When conveyer was inclined upwardly conveying, problem was particularly outstanding.When latch up phenomenon is serious, can make the cabinet cover plate arch play distortion, an axle moment of torsion increases suddenly, causes screw shaft to be killed or fault such as motor overload.Simultaneously because the drop-hanger bearing body is to be in the casing of exuberant bulk granular material to be dry condition work, inclement condition, common first seal failure, after be lubrication failure, the life-span just is a problem.
Hence one can see that, and the drop-hanger bearing body of this conveyor screw is the key that influences its result of use.If this bearing body of cancellation at first will solve the centering rotation that how to keep screw shaft, two kinds of situation promptly can appear: the one, and when being unkitted material, whole screw shaft be two end supports only, and centre portion is in free state, thereby produces than deep camber, causes sagging; The one, when packing material into, screw shaft receives the material effect and produces bigger arch power, damages the casing cover plate.The size of this power is relevant with the material carrying capacity again, and material is many more, and arch power is big more.Therefore, solve screw shaft centering rotation problem, will guarantee the gap of flight and casing and overcome screw shaft arch power.
Summary of the invention
The purpose of the utility model is to provide a kind of shaft type conveyor screw, and this carries function to eliminate the material latch up phenomenon, promotes operational throughput, improves the screw shaft mechanical characteristics.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of shaft type conveyor screw; Comprise driving device, side bearing, casing, screw shaft and centering rotation holding apparatus; Said screw shaft is for fixedly being equipped with the axis of flight, and flight is continuous on axis, and the screw shaft two ends are installed on the side bearing and by actuator drives;
Said centering rotation holding apparatus comprises pedestal, pressure roller, bearing, bolt, nut; Pedestal is made up of substrate and the earphone plate that is fixed on the substrate both sides, has bearing hole on the earphone plate, and the earphone plate on substrate both sides is symmetrical set; The substrate both sides have bolt hole; Pair of base is installed relatively, between pair of base, is provided with two pressure rollers, and the projecting shaft at pressure roller two ends is in the earphone plate bearing hole of bearing installation in pair of base; Pair of base is installed in the casing internal upper part through bolt and nut, two pressure rollers from both sides corresponding to the screw shaft flight that is installed in the casing.
Said pressure roller length is greater than two pitch of flight.
Said centering rotation holding apparatus evenly is provided with in casing at interval, and pressure roller is pushed down screw shaft from both sides from top to bottom.
The cooresponding bottom of shell inner face of said centering rotation holding apparatus one deck arc abrasion-proof backing block of applying ointment or plaster.
The utility model is on the basis of existing universal conveyor screw, to have adopted continuous screw shaft of flight and centering rotation holding apparatus; On the complete machine length of conveyer, there have not been the set drop-hanger bearing body of existing universal conveyor screw and the spacer flanger of connecting bolt axle; Thereby can eliminate the material latch up phenomenon; Promote operational throughput, increase and carry the inclination angle, improve the screw shaft mechanical characteristics.
The shaft type conveyor screw coefficient of admission of the utility model rises to 40-60%, carries the inclination angle to increase to 25 degree from maximum 20 degree that limit, and the screw shaft mechanical characteristics is greatly improved, and complete machine operation life greatly improves.
