Description

Bucket hoister with lower automatic tensioning structure

Affiliated technical field

The utility model relates to the Transport Machinery product, especially the bucket elevator used of grain processing.

Background technology

Bucket elevator is to use more Transport Machinery in the grain processing, is generally used for the vertical transport of material.In the special grain processing complete equipment, generally with the mass transport between bucket elevator solution process equipment.The bucket elevator that grain processing is at present used has two kinds substantially by the tensioning form: 1, utilize screw rod to regulate the follower bearing seat that is contained in the Xia Cang both sides, come tensioning winnowing pan band.To in time adjust after machine run a period of time, the winnowing pan band fluffed, and will guarantee two ends adjustment amount unanimity, to prevent winnowing pan band sideslip.This gig is an early production, uses many and wide.Existing problems are: need often to adjust, use inconvenience, in the course of conveying grain is had damage, the gig that has increases broken rate and can reach 0.1% when the material at the bottom of the conveying intensity.2, go up auto-tensioning, adopt driving wheel to be contained on rocking arm one end, utilize the other end of spring tension rocking arm, force the driving wheel that is in the storehouse to swing up and down, realize auto-tensioning.This gig adopts lower running velocity, has reduced gap at the bottom of winnowing pan and the storehouse with measures such as reduction Lower Hold material stocks.Its objective is the broken rate that increases that reduces convey materials.But stretching device designs on top, and is overhead higher, and structure is complicated, huge, the installation and maintenance difficulty.

Summary of the invention

The purpose of this utility model is the defective that overcomes prior art, and a kind of bucket hoister with lower automatic tensioning structure is provided, and it has kept the advantage of second kind of gig, and auto-tensioning design is in bottom, and compact conformation cost easy to adjust is low.

The purpose of this utility model realizes as follows: the driving wheel of gig is fixed in the storehouse, drives its rotation by motor through slowing-down structure.The follower of gig is contained in down in the storehouse by the bearing seat that is fixed on the Xia Cang both sides, and the regulating mechanism that bearing seat is moved up and down is arranged.Xia Cang top two the pipe respectively with base-mounted raising pipe, return duct free-running fit, following storehouse is contained in the base and can moves up and down, to satisfy the tensioning needs.Following storehouse central upper portion is adorned a compression spring, is connected with both sides above the base with thru-bolt, packing ring, nut by pressing plate, and tensioning power is provided.Feeder hopper is installed in storehouse, base up and down feeding inlet.

The advantage that this bucket hoister with lower automatic tensioning structure has is: auto-tensioning designs in bottom, and the compact conformation Installation and Debugging are convenient, low cost of manufacture, dependable performance.

Among the figure 1, base, 2, Xia Cang, 3, return duct, 4, compression spring, 5, winnowing pan, 6, the winnowing pan band, 7, raising pipe, 8, feeder hopper, 9, Shang Cang, 10, driving wheel, 11, pass a bridge, 12, motor, 13, pressing plate, 14, thru-bolt, 15, follower, 16, bearing seat, 17, at the bottom of the right storehouse, 18, at the bottom of the left storehouse.

The specific embodiment

With reference to accompanying drawing, bucket hoister with lower automatic tensioning structure by base, Xia Cang, return duct, compression spring, winnowing pan, winnowing pan band, raising pipe, feeder hopper, Shang Cang, driving wheel, gap bridge, motor, pressing plate, thru-bolt, follower, bearing seat, right storehouse at the bottom of, part is formed at the bottom of the left storehouse etc.Raising pipe 7, return duct 3, be contained on the base 1, last storehouse 9 is contained on raising pipe 7 return duct 3, and motor 12 is contained in raising pipe 7 outsides, and electrical machine belt pulley is connected with the big belt wheel of passing bridge with reduced speed 11 above being contained in it with bead apex.The small pulley of passing bridge with reduced speed 11 is connected with the belt pulley that drives driving wheel 10, can realize suitable running velocity.Follower 15 is contained in down in the storehouse 2 by the bearing seat 16 that is fixed on down 2 both sides, storehouse, two pipes on 2 tops, following storehouse respectively with base-mounted raising pipe 7, return duct 3 free-running fits, following storehouse 2 is contained in the base 1 and can moves up and down, to satisfy the tensioning needs.Following storehouse 2 central upper portion are adorned a compression spring 4, are connected with both sides above the base 1 by pressing plate 13 and thru-bolt 14 and packing ring thereof, nut, and tensioning power is provided.The bolt hole of installation shaft bearing 16 is the above-below direction elongated slot on the following storehouse 2, and the position of bearing seat 16 can be fixed on the bearing seat 16 by an end, and the double-screw bolt that the other end is connected down storehouse 2 lower flange webs is adjusted to behind the position that needs fixing with two nuts.With the axis of assurance follower 15 and the parallel axes of driving wheel 10, prevent winnowing pan band sideslip in service.At the bottom of the right storehouse 17, at the bottom of the left storehouse 18, be contained in down on 2 lower flanges of storehouse with screw, packing ring, nut, composition is the semicircle inner chamber at center with follower 15 installation sites, ragged edge has rational gap with following storehouse 2 inner chambers when making winnowing pan 5 operations, to reduce the material stock in storehouse 2 down.Because 18 convenient disassemblies at the bottom of the right storehouse 17, at the bottom of the left storehouse help installation, inspection, the maintenance of machine.Feeder hopper 8 is installed in storehouse, base 1 up and down 2 feeding inlet, the material that promotes can enter down storehouse 2 by feeder hopper 8.The winnowing pan band 6 of filling winnowing pan 5 at a certain distance is contained on driving wheel 10 and the follower 15.Storehouse 2 is in the limes superiors position of base 1 under the new gig of installing, and make follower 15 axis and driving wheel 10 parallel axes by the bearing seat of adjusting down on the storehouse 2 16 this moment, to prevent winnowing pan band 6 sideslips in service.When gig work a period of time, winnowing pan band 6 elongation backs follower 15 under the effect of compression spring 4 in time moves down with following storehouse 2, realizes the tensioning of winnowing pan band 6.The gig long-term work, when following storehouse 2 is tensioned to the smallest limit position of base 1, can be by the method for brachymemma winnowing pan band 6, make that storehouse 2 returns to initial position under the gig.Material enters winnowing pan 5 by hopper 8, is rising to storehouse 9 under the drive of winnowing pan band 6, outside return duct 3 on the discharging opening in storehouse 9 flow out.
