Abstract

The utility model relates to a plate chain continuous bucket elevator. A tension sprocket and a subassembly (7) of the tension sprocket move horizontally a certain distance corresponding to a drive sprocket and a subassembly (1) of the drive sprocket toward a charging opening (6); a plate chain (4) corresponding to the charging opening (6) and a discharge opening (9) is respectively provided with a spacing and chain pressing device (3); the plate chain (4) is pressed inward into a vertical shape. A material guiding slot (8') and a material guiding slot (8) are respectivelyarranged in the charging opening (6) and the discharge opening (9), which can eliminate the phenomenon that materials scatter in a housing (5) and can eliminate resistance generated when the materials is fetched from the bottom of the housing (5). The utility model can reduce the abrasion of components, can save electricity and can reduce maintenance and cost.

Description

Plate chain bucket gig

The utility model relates to a kind of plate chain bucket gig.

At present, bucket elevator is the vertical transport machinery of widespread use in the building materials industry factories and miness, and is disclosed as " building material machinery and equipment " (China Construction Industry Press publishes in December, 1981).Bucket elevator is divided into belt and chain type two classes by the tow chain component form.In caterpillar elevater, plate chain bucket gig is the most frequently used a kind of, and this gig is made up of casing, tow chain member and affixed thereon hopper and charging door, discharge port.The tow chain member is made up of the idler sprocket of the drive sprocket at top and assembly and bottom and assembly thereof and plate chain; Charging door and discharge port are located at the opposite side of casing upper and lower respectively.During work, under the engine installation driving of (containing retarder), the plate chain is made circulating motion up and down together with hopper, material rises to the top from the charging door hopper of packing into, when hopper turns over drive sprocket, the hopper mouth down, material slips to discharge port by the back guide groove of gravity by next hopper and draws off.But there is following shortcoming in the gig of this structure: drive sprocket and idler sprocket design are on same vertical line, in real work, there is partial material to be scattering in the casing, aggravated the wearing and tearing of INT COMP from the inner edge and the gap location between the hopper of charging door, discharge port.The solid accumulation that is scattered is at bottom of shell, produce when making hopper walk around idler sprocket and draw the phenomenon of getting material, increased shovel material resistance, cause the increase of power consumption and the accelerate the failure of member, make the gig uptime shorten, need often maintenance, and the maintenance difficulty is complicated, wastes time and energy and influence production.

The utility model proposes a kind of plate chain bucket gig, can eliminate effectively material in casing be scattered and hopper is drawn and is got the material phenomenon, reach to save power consumption, reduce the wearing and tearing of tow chain member, reduce maintenance, reduce the purpose of service expenditure.

For achieving the above object, the utility model adopts following solution: it comprises casing, drive sprocket and assembly thereof, idler sprocket and assembly thereof, plate chain, be fixed on the plate chain hopper and at the discharge port and the charging door of relative two sides, casing upper and lower part.The utility model changes the design that former drive sprocket and assembly thereof and idler sprocket and assembly thereof are on the same vertical line into not on same vertical line, the center that is about to idler sprocket and assembly thereof with respect to drive sprocket and assembly thereof to charging door direction translation certain distance; Install deflector chute in charging door additional, the top that deflector chute probes into the up hopper of walking around idler sprocket relatively can all be dissolved in the hopper to material from deflector chute; In discharge port, also install deflector chute additional, correspondingly in casing stretch into and extend upwardly to the casing top; Add respectively corresponding to the plate chain place of charging door and discharge port and to put a spacing pressure chain apparatus, the plate chain inwardly is depressed into vertically.

After adopting such scheme, because the deflector chute of charging door probes into the top of the up hopper of walking around idler sprocket relatively, even partial material is scattered time from the gap location of hopper and deflector chute inward flange in charging, also can be caught by following hopper, guaranteed the material hopper of all packing into; The hopper that material is housed of walking around drive sprocket relatively control is gone in the deflector chute of discharge port, can all enter the deflector chute of discharge port when material falls down and draws off.Thereby eliminated material in casing be scattered and hopper is drawn at bottom of shell and to be got the resistance that material produces, reach to reduce the member wearing and tearing, save because of overcoming and draw the material electric energy that resistance consumed, reduce frequency of maintenance, the purpose of reduction service expenditure.

Fig. 1 is the section of structure of the utility model plate chain bucket gig.

Fig. 2 is the another kind of form of the spacing pressure chain apparatus of gig shown in Figure 1.

In the embodiment in figure 1, the center of idler sprocket and assembly 7 thereof to charging door 6 direction translation certain distances, is about 200mm with respect to drive sprocket and assembly 1 thereof.At plate chain 4 places corresponding to charging door 6 and discharge port 9, install the spacing pressure chain of the wear-resisting flat strip shaped arc of a pair of steel guide plate 3 respectively additional, the modulus that also can install additional as shown in Figure 2 is identical with plate chain 4, the spacing pressure chain sprocket wheel 3 that reference diameter suits ' and, plate chain 4 inwardly is depressed into vertically; Charging door 6 install additional deflector chute 8 ', in casing 5, extend into material in the deflector chute 8 ' hopper 2 of all packing into; Discharge port 9 installs deflector chute 8 additional, correspondingly in casing 5 stretches into and extend upwardly to casing 5 tops.

Claims

1, a kind of plate chain bucket gig, it comprises casing (5), drive sprocket and assembly thereof (1), idler sprocket and assembly thereof (7), plate chain (4), be fixed in the hopper (2) on the plate chain (4) and divide discharge port (9) and the charging door (6) be located at the upper and lower relative both sides of casing (5), it is characterized in that: the center of idler sprocket and assembly thereof (7) with respect to drive sprocket and assembly (1) thereof to charging door (6) direction translation certain distance; Dress deflector chute (8 ') also probes into the top of the up hopper (2) of walking around idler sprocket and assembly (7) thereof relatively in charging door (6); Dress deflector chute (8) in discharge port (9) correspondingly in casing (5) stretches into and extends upwardly to casing (5) top; Plate chain (4) corresponding to charging door (6) and discharge port (9) is located, and installs spacing pressure chain apparatus respectively additional.
