Abstract

The utility model relates to a chain conveyor for continuous conveying of high-temperature materials, which is characterized in that the chain conveyor is composed of a redirection drum device, a machine frame, a chain delivery device, a support carrying roller, and a drive drum device with a tension slide track. The redirection drum device and the support carrying roller are fixedly connected to the bolt of the machine frame. The drive drum device is fixed on the machine frame. The chain delivery device is engaged with the redirection drum device and the drive drum device and arranged on the support carrying roller. The chain delivery device is composed of the chain I, the chain II, a chain mat whose two ends are respectively fixed to the chain I and the chain II. Besides, the chain mat is fixedly connected to a flat strip. The utility model has the advantages of stable and reliable operation of the device and convenient maintenance.

Description

Chain conveyor

Technical field

The utility model belongs to a kind of material continuous conveying device, particularly a kind of high-temperature material device of conveying continuously that is used for.

Background technology

Known at present, the feedway of bittulith continuous feeder is realized the continuous conveying of bittulith, common material continuous conveying device has traditional drum belt formula, driving cylinder by power unit rotates, rely on friction force between the two to drive the whole piece belt movement, have the tensioning slideway at driven end, can play the effect of tightening belt, this apparatus structure is simple, easy to maintenance, price economy, but belt-driving skids easily and throws switch, easy sideslip, traveling comfort, poor reliability.Again because the temperature of bittulith generally at 170 ℃, causes the adhesive tape temperature distortion easily, can make the slipping of the belt phenomenon that throws switch more serious.Also having a kind of form of common material continuous conveying device is the scraper chain driving type, and its structure is: the power unit outputting power drives driving chain wheel and rotates through the reductor back of slowing down, thus drive roller chain and move simultaneously with carrier bar that roller chain is connected.This device operates steadily, reliably, but friction drag is big, difficult in maintenance in the transmission, especially cleaning is bonded in the unusual difficulty of pitch on the carrier bar.

Summary of the invention

The utility model provides a kind of chain conveyor for solving the technical matters that exists in the known technology, and this device operates steadily, reliably, and is easy to maintenance.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of chain conveyor, comprise the changed course roller device, frame, chain conveyor, support carrying roller, the head roll device that has the tensioning slideway, the changed course roller device, supporting carrying roller captives joint with frame, the head roll device is installed on the frame, chain conveyor and changed course roller device, the engagement of head roll device, and be supported on and support on the carrying roller, wherein the concrete structure of chain conveyor is: simultaneously with the changed course roller device, head roll device ingear chain I, be connected with a plurality of adjacent carrier bars on the chain II, it is characterized in that: on described carrier bar, be fixed with the flat pattern band.

Advantage and the good effect that the utlity model has are: owing to adopt the version of the flat pattern band that is connected on carrier bar, combine two kinds of devices of drum belt formula and scraper chain driving type advantage separately, this device operates steadily, reliably, and is easy to maintenance.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cut-away view of Fig. 1.

Label among the figure is respectively:

1 changed course roller device, 2 frames, 3 chain conveyors, 4 support carrying roller, 5 head roll devices,

The 5-1 HM Hydraulic Motor, 5-2 reductor, 5-3 bearings I, 5-4 sprocket wheel I, 5-5 sprocket shaft, 5-6 sprocket wheel II, 5-7 bearings II, 8 pins, 3-1 chain I, 3-2 chain II, 3-3 link plate, 3-4 rivet, 3-5 adhesive tape.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1,2, a kind of chain conveyor, comprise changed course roller device 1, frame 2, chain conveyor 3, support carrying roller 4, the head roll device 5 that has the tensioning slideway, changed course roller device 1, it is affixed with frame 2 bolts to support carrying roller 4, head roll device 5 is connected with frame 2, owing to have the tensioning slideway, the adjustable positions of head roll device 5, chain conveyor 3 and changed course roller device 1,5 engagements of head roll device, and place and support on the carrying roller 4, wherein chain conveyor 3 comprises chain I3-1, chain II3-2, also have two ends to be individually fixed in a plurality of adjacent carrier bar 3-3 of chain I chain II, on carrier bar 3-3, be fixed with adhesive tape 3-5 with rivet 3-4.Promptly on the basis of the scraper chain feedway of known technology, adhesive tape is connected on carrier bar.

Operating principle of the present utility model: the band conveyor of this driving system and traditional drum driven as seen from Figure 1 is essentially different on driving system.The type of drive of traditional drum driven is directly to drive cylinder by power unit to move, and the utility model is then moved through reductor deceleration rear driving wheel as power unit by HM Hydraulic Motor, thereby drive chain and adhesive tape are synchronized with the movement.The stable drive of this utility model, the reliability height can actv. prevents the belt deviation problem of conventional belt conveyer, has also solved simultaneously because the high temperature during conveying pitch influences the problem of the stationarity of the reliability of sealing-tape machine and conveying.

Fig. 2 is the A-A cut-away view of Fig. 1, and HM Hydraulic Motor 5-1 drives reductor 5-2, and reductor drives sprocket wheel I5-4, sprocket shaft 5-5, sprocket wheel II5-6 rotate, and there are bearings I5-3 and bearings II5-7 in sprocket shaft 5-5 two ends, constitute head roll device 5.Transmission adhesive tape 3-5 is solidified as a whole by connecting rivet 3-4 and a plurality of adjacent carrier bar 3-3, and carrier bar 3-3 is solidified as a whole with chain I3-1 and chain II3-2 by set pin 8.Thereby guaranteed the motion of adhesive tape 3-5 and chain synchronous same-speed.Changed course roller device 1 is compared with the structure of head roll device 5, and no tensioning slideway mechanism, unpowered part promptly do not have HM Hydraulic Motor, reductor, and the bearings at two ends has the mechanism that flexibly connects with frame, and other parts are identical with head roll device 5.

The utility model has adopted a kind of and the distinct type of drive of conventional apparatus, can be described as the fine combination of two kinds of devices, in conjunction with two kinds of devices advantage separately, eliminates shortcoming separately and a kind of optimal combination of drawing.The utility model can not only rely on scraper plate chain-drive stationarity to eliminate the fugitiveness of drum belt transmission and the phenomenon of the easy sideslip of belt, utilize the characteristics of drum belt transmission to eliminate all drawbacks of scraper plate chain-drive simultaneously, simple more, convenient as cleaning easy to maintenance, pitch, its friction drag also reduces greatly.
