Bucket elevator
Technical field:
The utility model belongs to a kind of gig, relates in particular to the bucket elevator in the forced action type asphalt mixing plant.
Background technology:
Gig is widely used in a plurality of fields such as industrial and mining enterprises, chemical industry metallurgical as a kind of lift mechanism, and bucket elevator mainly is the elevating gear that powdery or granular bulk material is risen to certain altitude with elevator bucket.It mainly comprises gig housing, driving wheel, follower, plate chain, feed inlet and outlet and driving device, driving device links to each other with driving wheel and is positioned at the top of housing, discharging opening is positioned at position relative with driving wheel on the housing, follower is fixed on the driven axle, driven axle is fixed on lower part of frame by bearings at both ends and bearing seat, the stationkeeping of bearing seat is constant, between driving wheel and follower, be connected with the plate chain, be fixed with a plurality of chain buckets on the plate chain, on the corresponding housing of follower, be provided with inlet point.Gig drives driving wheel by driving device and rotates, and driving wheel drive plate chain rotates, and carries material thereby the plate chain drives chain bucket.The fixed gig of this follower is had relatively high expectations to the squareness of housing, simultaneously, gig driving wheel in top is very difficult corresponding consistent again with the bottom follower when mounted, and can't adjust, cause and in use easily fall the chain phenomenon, cause influences such as stopping production for the production user.
Summary of the invention:
At the problem that above-mentioned gig exists, it is a kind of simple in structure that the purpose of this utility model is to provide, the bucket elevator that flower wheel can in axial direction be adjusted.
For achieving the above object, the technical scheme that this bucket elevator adopts is as follows: bucket elevator comprises inlet point, discharging opening, housing, driving wheel, follower, driving device, carrier bar and chain bucket, driving wheel links to each other with driving device and is positioned at the top of housing, on the housing of driving wheel opposite position, be provided with discharging opening, be connected by the plate chain between follower and the driving wheel, chain bucket is fixed on the plate chain, follower is packed on the driven axle and places lower housing portion, be provided with inlet point on the housing of follower opposite position, the housing that is positioned at described follower opposite position is provided with the axial adjusting device of follower.
The follower axial adjusting device is for being respectively equipped with two slide rail adapter plates in the relative both sides of housing, two slide rail adapter plates of each side are vertically corresponding to be provided with, the slide rail adapter plate is provided with long slot bore along the driven axle axis direction, bolt passes long slot bore and is fixed on the adjustable slide rail, be connected with a clamp nut on the bolt, bearing is housed in the bearing seat, and the bearing seat outside is provided with sliding-rail groove, and adjustable slide rail is stuck in the sliding-rail groove.
Adopt the beneficial effect of technique scheme: the housing of follower opposite position is provided with the axial adjusting device of follower, this setting device is for being respectively equipped with two slide rail adapter plates in the relative both sides of housing, the slide rail adapter plate is provided with long slot bore along the driven axle axis direction, bolt passes long slot bore and is fixed on the adjustable slide rail, be connected with a clamp nut on the bolt, bearing is housed in the bearing seat, the bearing seat outside is provided with sliding-rail groove, adjustable slide rail is stuck in the sliding-rail groove, and the driven axle two ends cooperate with bearing.When deviation appears in the follower position of the driving wheel on top and bottom, can unclamp the clamp nut on the bolt, thereby bolt is slided along the long slot bore on the slide rail adapter plate, and then drive the slip of bearing seat, driven axle, realize adjustment to follower.Have simple in structurely, follower can axially be adjusted, and makes stable drive, has reduced the generation of falling chain.

The specific embodiment:
Below in conjunction with accompanying drawing specific embodiment of the utility model is further described.Bucket elevator as shown in Figure 1, has inlet point 1, discharging opening 2, housing 4, driving wheel 3, follower 5, driving device, carrier bar 7 and chain bucket 6, driving wheel 3 is fixed on the imput shaft, imput shaft is bearing in the top of housing 4, driving device links to each other with imput shaft, with the housing 4 of driving wheel 3 opposite positions on be provided with discharging opening 2, follower 5 is packed on the driven axle 8 and places housing 4 bottoms, be connected by plate chain 7 between follower 5 and the driving wheel 3, chain bucket 6 is fixed on the plate chain 7, with the housing of follower 5 opposite positions on be provided with inlet point 1, the housing that is positioned at described follower 5 opposite positions is provided with the axial adjusting device of follower.
Setting device as shown in Figure 2 is for being respectively equipped with two slide rail adapter plates 9 in the relative both sides of housing 4, two slide rail adapter plates of each side are vertically corresponding to be provided with, slide rail adapter plate 9 is provided with long slot bore 12 along the driven axle axis direction, bolt 10 passes long slot bore 12 and is fixed on the adjustable slide rail 14, be connected with a clamp nut 11 on the bolt 10, in the bearing seat 13 bearing is housed, bearing seat 13 outsides are provided with sliding-rail groove, adjustable slide rail 14 is stuck in the sliding-rail groove, follower 5, driven axle 8, bearing seat 13 integral body can move up and down along adjustable slide rail 14, can realize plate chain 7 degrees of tightness are regulated.Unclamp clamp nut 11, follower 5, driven axle 8, bearing seat 13, adjustable slide rail 14 and bolt 10 integral body can endwisely slip along long slot bore 12, realize the adjustment axial to follower 5.
