Description

Conveying belt of plate type conveyer

The utility model relates to a kind of transport plane, particularly relates to a kind of platform conveyer, belongs to the Transport Machinery of loose unpacked material.

Platform conveyer of the prior art, mostly particularly mining heavy-duty plate transport plane is that two head sprockets on the same main shaft of transmission drag by two groups of hinged slat conveyeres that constitute of chain, carry out the transportation of loose unpacked material by two cover main drive gears.The carrier bar of each carrier bar joint of this load-transfer device exceeds the Effective width of convey materials than broad, and side connects two chains respectively outside the at both ends riser.At a kind of plate belt feeder of U.S.'s public use, accompanying drawing 1 to Fig. 4 is the accompanying drawing of explanation prior art.Accompanying drawing 1, it is its shape assumption diagram, drive main shaft (3) and head sprocket (4) and be supported on carriage (5) and be connected on the main stand (10) by electrical motor (1) transmission speed reducer (2), (6) be that carrier bar and riser constitute feeding groove, (7) be chain, (8), (9) respectively are guiding carrier bar and tensioner adjusting mechanism.

Accompanying drawing 2 is structure construction front views of its carrier bar joint, and accompanying drawing 3 is birds-eye vieies of Fig. 2, and accompanying drawing 4 is its side direction views.The two ends symmetry of carrier bar (15) respectively has riser (11), its outside has gusset (12) and riser (11) and carrier bar (12) to be welded to connect, both sides at gusset (12) make carrier bar (15) be connected one with chain section (13) with bolt (14), (16) be the fixed stop flitch that breaks away from load-transfer device, (17) be shelves material square steel on the carrier bar, (18) be crossbeam, (19) are arcs, and (20) are the carrier bar top shoes.From said structure, the carrier bar of this structure is long, its two ends respectively have the distance of installing between chain portion two chains to exceed the Effective width of the material conveying of this carrier bar, therefore its weak point is that this slat conveyer overall width is strengthened, brought the inconvenience that moves, transfer motion power consumption is also than higher.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provide a kind of under the situation of equal effectively transport capacity, both had the defeated material of equal actv. width, reduce the light-duty slat conveyer of auxiliary width again, make the main transmission structure compactness, oad reduces, and total weight alleviates, mobile light, transfer motion power consumption reduces.

The purpose of this utility model can reach by following measure: load-transfer device is to be made of by two groups of chains are hinged a plurality of carrier bars joint, carrier bar two ends at each carrier bar joint respectively has a riser, constitute flute profile, shelves material square steel is arranged in the groove, crossbeam is arranged at the bottom, carrier bar is to dispose in the Effective width of carrier bar material conveying with being connected of chain section, the connection chain setting plate of carrier bar trench bottom welding usefulness, with fastener such as bolt, carrier bar and chain section are connected as one, between carrier bar and adjustment plate, insert and weld arc with putty effect.

The purpose of this utility model can also reach by following measure: the carrier bar of each carrier bar joint, adjusting plate and arc links into an integrated entity with welding or forging type, carrier bar and chain section are to adjust thickness and make on the least significant end of arc and the chain and have 3 to 5mm between the plane by adjusting plate, maximum is no more than the gap of 6mm, the outer rim arc of this arc shape is identical with the trajectory shape of back chain front edge of board operation, when this track is taken from carrier bar at least and is walked around tooth pitch of sprocket wheel revolution or when being equivalent to 26 °～27 ° of angles of revolution, the track that this carrier bar moved, avoid interfering in the rotation of carrier bar and chain anti-simultaneously leak-stopping material.

The utility model has following advantage compared with the prior art:

1, owing to two chain sections of the utility model employing and being connected of carrier bar, it is the technical scheme that in the Effective width of carrier bar material conveying, disposes, the load-transfer device overall width is reduced, and its reduction is at least 30% of bandwidth of the prior art, because two chain stripe pitch are from minimizing, the main transmission structure compactness, the gross weight of equipment amount alleviates, and alleviates 10% of gross weight in the prior art at least, thereby saves raw MAT'L, reduce manufacturing cost, reduce cost.

2, because this platform conveyer load-transfer device width reduces, move the weight saving of part, thereby reduced the operation consumption of power.

3, because the total weight of this platform conveyer alleviates, corresponding bringing moved the light effect that is suitable for the many places operation.

The drawing of accompanying drawing is described as follows:

Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are the explanation prior aries, and the structure construction figure of plate belt feeder is illustrated in describing prior art.

Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9 are the structure construction figure of the technical solution adopted in the utility model and embodiment, are described as follows:

Fig. 5 is the front elevation of the load-transfer device of the utility model platform conveyer.

Fig. 6 is a birds-eye view of the present utility model.
