A kind of screw conveyor, including rack 1, transmission road 2, rotary electric machine 3, carrier bar 4, drive sprocket 5, driven sprocket 6,
Chain 7 and chain tensioning device are fixed with transmission road 2 in the rack 1, and transmission road 2 is helical channel, and chain 7 is fixed on chain
4 bottom of plate, carrier bar 4 are slidably connected with transmission road 2, are fixed with drive sprocket 5 in the shaft of rotary electric machine 3, drive sprocket 5 with from
Movable sprocket 6 engages respectively with chain 7, and driven sprocket 6 is movably connected in rack 1, and driven sprocket 6 is equipped with chain tensioning device.
Track 8 is fixed in the transmission road 2, the contact surface of track 8 is arc, and 4 bottom of carrier bar is fixed with for the cunning of matching track 8
Dynamic portion 9.The sliding part 9 is made of fixed frame 91 and collar 92, and collar 92 is rotatably connected on fixed frame 91, outside collar 92
Circle fits with track 8.The sliding part 9 is baltimore groove, and track 8 passes through baltimore groove.The driven sprocket 6 is rotatably connected on
One end of bar 10, the other end of bull stick 10 are hinged in rack 1, and chain tensioning device is hinged on the shaft of bull stick 10.The chain
Stretcher is by position-limiting drum 11, spring 12, threaded rod 13 and nut 14, and threaded rod 13 is through position-limiting drum 11 and spring 12, screw thread
Nut 14 is arranged on bar 13, spring 12 is between position-limiting drum 11 and nut 14, and position-limiting drum 11 is hinged in rack 1, screw thread
13 bottom of bar is hinged on bull stick 10.The material of the track 8 is polyurethane.
There are two types of patterns for the sliding part 9 of 4 bottom of carrier bar of the present invention.As shown in Figure 3,4 bottom of carrier bar is fixed with fixation
Respectively there are one group of collar group in frame 91, fixed frame left and right ends, and each collar group is made of two symmetrically arranged collars 92, two axis
The outer ring of ring 92 is fitted in the both sides up and down of the arcwall face of a track 8 respectively.Such two groups of collar groups are fitted in transmission respectively
On the track 8 of 2 left and right ends of road, so as to fulfill being slidably connected for the carrier bar 4 and transmission road 2.As shown in Figure 4,4 bottom of carrier bar
Symmetrically arranged baltimore groove there are two fixed, towards the direction of track 8, track 8 passes through baltimore groove, utilizes rail the opening of baltimore groove
Road 8 is embedded in realization in baltimore groove and is slidably connected.Possess two kinds of carrier bars 4 of different sliding parts 9, it can be by a kind of wherein independent carrier bar
4 connections are combined into transmission device, can also two kinds of 4 Hybrid connections of carrier bar be formed transmission device.
With reference to shown in attached drawing 1 and attached drawing 2, carrier bar 4 is laid with along the track of transmission road 2, since transmission road 2 is helical form,
Therefore carrier bar 4 is also helical form.Drive sprocket 5 is connected to 1 top of rack, and driven sprocket 6 is connected to 1 bottom of rack, drive chain
Wheel 5 and the shaft of rotary electric machine 3 are connected, and 7 inner ring of chain of 4 bottom of carrier bar engages respectively with drive sprocket 5 and driven sprocket 6.
So when rotary electric machine 3 starts, carrier bar 4 will be driven to be transmitted along transmission road 2.Article is placed on carrier bar 4, just
It can realize transmission of the article on carrier bar 4.Rotary electric machine 3 carries out positive and negative rotation, it is possible to control carrier bar transmission direction about 4
Change.
As shown in Figure 5, driven sprocket 6 is equipped with chain tensioning device, can be certainly after having been grown due to 7 usage time of chain
It so stretches, so as to cause can not to be tensioned between chain 7 and sprocket wheel, it is possible to can occur to jump tooth, it is therefore desirable to use chain tension
Device helps tension chain 7.Position-limiting drum 11 rotates on a fulcrum, and threaded rod 13 can move down on position-limiting drum 11 is interior
It is dynamic, and spring 12 can not pass through position-limiting drum 11 and nut 14.11 bottom of threaded rod is hinged on bull stick 10, and 10 end of bull stick is cut with scissors
It is connected in rack 1.When needing tension chain 7, rotary nut 14, nut 14 is just moved along threaded rod 13 toward the direction of spring 12
Dynamic, spring 12 is subject to the extruding of nut 14 at this time, and spring 12 will be tensioned, and tensioning when will support threaded rod 13 down,
Under the tension of spring 12, bull stick 10 will down be rotated along the fulcrum in rack 1, and the driven sprocket 6 on bull stick 10 is just
It can move down, chain 7 will be tensioned in the folding process of driven sprocket 6 at this time.And chain tensioning device side is equipped with light
Electric inductor, for chain tensioning device because chain 7 relaxes and spring can be caused to open, sensing metallic plate can follow chain tensioning device one
Rise move down, when spring opens up into it is a certain amount of when, sensing metallic plate departing from photoelectric sensor, photoelectric sensor will
Alarm is sent, notifies staff to be adjusted maintenance to entire carrier bar 4.
Track 8 uses PU elastic materials, can not only ensure that carrier bar 4 reduces noise during slip, and can be with
Reduce vibrations when sliding.
Using above-mentioned desirable embodiment according to the invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determine its technical scope according to right.
