Abstract

The utility model relates to a bucket elevator, which is mainly characterized by comprising a driving chain wheel, a driven wheel, a chain, a box body of the bucket elevator, a material hopper, a motor, a speed reducer, a chain tensioning device, and a chain back-stopper, wherein the chain consists of an internal chain plate, an external chain plate and a roller sheathed on a shaft sleeve; the pitch length of the internal chain plate and the external chain plate is shortened; the section areas of the internal chain plate and the external chain plate are increased; and the driven wheel is a toothless smooth wheel. Through the adoption of the technical scheme, the pitch length of the chain plates is shortened, the section areas of the chain plates are increased, the tensile resistance and torsional resistance of the chain is improved, the chain plates with short pitch length are adopted, the chain runs stably and a special guide rail does not need to be arranged in the box body, thus greatly reducing the possibility that the material hopper is impacted; the driven chain wheel at the lower part is changed from a gear to the toothless smooth wheel; the toothless smooth wheel can act as the guide rail, thus avoiding the phenomenon of broken chain under great tensile stress owning to material gluing of the driven chain wheel and the further tooth-climbing of the chain.

Description

Bucket elevator

Technical field

The utility model belongs to the bont of transported material, is specifically related to a kind of bucket elevator.

Background technology

At present, existing bucket elevator mainly is made up of parts such as drive sprocket, driven sprocket, chain, bucket elevator casing, hopper, motor, reductor, chain swelling device, chain holdbacks.Its common advantage be the equipment traffic capacity strong, operate steadily, floor area is little, hoisting depth is high, running noises is little; Its shortcoming is in service because its chain is subjected to the effect of tensile stress and the flexure stress when promoting with the drive sprocket incision for a long time, the carrier bar fatiguability fracture of chain, next adds that some material that is transferred is easy to again bond in the race of last lower sprocket, especially on lower sprocket, material is pressed by the chain medicated roll, bonded assembly material is too many between the groove of the gear teeth, and then cause the wheel pitch of teeth to change, chain and sprocket engagement are bad in operational process, the chain climbing tooth appears by the click phenomenon, again because its inner space is little, in case chain disconnected and drop in the casing after, overhaul very inconvenient.

Summary of the invention

Be prone to the chain climbing tooth in order to overcome existing bucket elevator, fracture causes the deficiency that bucket elevator can't normal operation, the utility model provides a kind of bucket elevator, and this bucket elevator can use more long period and chain climbing tooth and fracture not occur, has improved the normal operation cycle of bucket elevator.

It is that this bucket elevator comprises drive sprocket, flower wheel, chain, bucket elevator casing, hopper, motor, reductor, chain swelling device, chain holdback that the utility model solves the problems of the technologies described above the technical scheme of being taked, chain by inner plate, pin link plate, axle sleeve and on axle sleeve the roller bearing of socket form, wherein the pitch of inside and outside carrier bar shortens, the sectional area of inside and outside carrier bar increases, and flower wheel is anodontia halo.

The utility model adopts technique scheme, shortens the carrier bar pitch, increases the sectional area of carrier bar, improve chain tension anti-twisting property, adopt the carrier bar of short pitch, chain operates steadily, need not in the casing specific guide rail is installed, thereby reduced the possibility that hopper is collided greatly; Make the driven sprocket of bottom into anodontia halo by gear, anodontia halo is equivalent to the effect of guide rail, thereby can avoid because of the driven sprocket binding material, and then the chain climbing tooth takes place, and chain is subjected to huge tensile stress and the chain rupture phenomenon.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the transmission device schematic diagram of this novel bucket elevator.

Fig. 2 is the chain structure scheme drawing of this novel bucket elevator.

The specific embodiment

Referring to Fig. 1, Fig. 2, bucket elevator described in the utility model comprises: drive sprocket 1, flower wheel, chain 3, bucket elevator casing 4, hopper, motor, reductor, chain swelling device, chain holdback, chain 3 by inner plate 3.1, pin link plate 3.2, axle sleeve 3.3 and on axle sleeve the roller bearing of socket form, wherein inside and outside carrier bar 3.1,3.2 pitch shorten to original 2/3rds, the sectional area of inside and outside carrier bar 3.1,3.2 increases to original 2 times, and driven sprocket is replaced by anodontia halo 2.

Claims

1. bucket elevator, comprise drive sprocket, flower wheel, chain, bucket elevator casing, hopper, motor, reductor, chain swelling device, chain holdback, it is characterized in that chain by inner plate, pin link plate, axle sleeve and on axle sleeve the roller bearing of socket form, wherein the pitch of inside and outside carrier bar shortens, the sectional area of inside and outside carrier bar increases, and flower wheel is anodontia halo.
