Specific embodiment

Specific embodiment of the present utility model is further illustrated with reference to the accompanying drawing:

Such as Fig. 1-Fig. 5, a kind of bucket type blanking device of band casting machine, bucket type blanking device is located at 1 discharge end of casting machine Between finished product bucket 7, bucket type blanking device includes material-gathering device 3 and device for discharging 4, and material-gathering device 3 includes aggregate bin 8, sector Valve 11, idler wheel 14, counterweight 10, limiter 12；Aggregate bin 8 is fixed on casting machine main frame 2.The lower section of aggregate bin 8 For feed opening 13, feed opening 13 is externally provided with segmental valve 11, and segmental valve 11 is hinged by pin shaft and aggregate bin 8, segmental valve 11 two sides are respectively equipped with strut 1 and strut 29, and the end of strut 1 is equipped with idler wheel 14, and the end of strut 29 is hung Counterweight 10, strut 1 and strut 29 are arcuate structure.The outer wall of aggregate bin 8 is equipped with limiter 12.

Device for discharging 4 is equipped with below material-gathering device 3, device for discharging 4 includes transport mechanism, dump skip 16, elastic damper 18, valve driving lever 19；Transport mechanism includes drive sprocket 17, driven sprocket 21, chain belt 20, driving motor 5, cycloidal-pin wheel deceleration Machine 6, drive sprocket 17 and driven sprocket 21 are to be vertically arranged up and down, and driving motor 5 is connect with cycloidal planetary gear speed reducer 6, cycloid Pin gear speed reducer 6 drives drive sprocket 17 to rotate, and chain belt 20 is driven to rotate, and chain belt 20 is equipped with multiple dump skips 16, dump skip 16 top is connect by elastic damper 18 with chain belt 20, and elastic damper 18 includes pull rod 24, otic placode 23, spring 25, is drawn Sheathed spring 25 and otic placode 23 on bar 24,25 one end of spring are fixedly connected on pull rod 24, and the other end is fixedly connected with otic placode 23, Otic placode 23 is fixed on 16 outer wall of dump skip, and pull rod 24 and chain belt 20 are hinged.

The base angle of dump skip 16 and the chain rivet 22 of transport mechanism are hinged, and 16 top of dump skip is fixedly connected with taintor valve driving lever 19, when dump skip 16 runs to 8 lower section of aggregate bin, valve driving lever 19 pushes the segmental valve 11 of aggregate bin 8 aside, expects ingot from aggregate bin 8 fall into dump skip 16, and aggregate bin accepts material ingot, are transported to dump skip, and material ingot is discharged in finished product bucket by dump skip again, the company of realization Continued access material and blanking.

When casting machine needs discharging, bucket type blanking device is started, the material ingot on casting machine in ingot mould falls into aggregate bin first In, segmental valve is in close state at this time, with the movement of chain belt, when one of dump skip is run to close to aggregate bin When, the valve driving lever on dump skip stirs the idler wheel on segmental valve, then segmental valve is gradually opened material ingot and fallen into dump skip, Dump skip does continuous movement, and after the dump skip leaves aggregate bin, segmental valve voluntarily closes under counterweight effect and under When one material ingot reaches, continue splicing.It is moved downward in the dump skip while next dump skip is to moving under aggregate bin, completed Discharging charging movement, carries out in cycles.The dump skip of charged ingot is flipped when running near driven sprocket, and material ingot falls Enter in finished product bucket, completes discharging movement.To accomplish to realize slow discharging, the unexpected overturning of dump skip is avoided, in dump skip and chain Elastic damper is installed between band, achievees the purpose that expect that ingot is slowly tumbled, to reduce material impact to the maximum extent, to make powder Broken rate is preferably minimized.The speed of service of dump skip can be according to the casting machine ingot mould speed of service and needing through driving motor tune Section.

The utility model reasonable integral structure, bucket type device for discharging and casting machine no-float, using bucket type device for discharging Discharging reduces material height of fall to the maximum extent, realizes material and gently unloads, efficiently avoid between material and material with Impact between chute and steel finished product bucket significantly reduces brittle material degradation rate.Therefore alloy finished product rate greatly improves, The chip index of alloy is reduced to 3% and required hereinafter, meeting product standard, reduced the disposition of rejected product by 8% or more original Rate reduces production cost, improves economic benefit.

Described above is only the basic principle of the utility model, is not imposed any restrictions to the utility model, all foundations The utility model carries out equivalent variations and modification to it, within the scope of the art of this patent protection scheme.
