The utility model is characterized in that the chain plate conveying belt is formed in the mode that a plurality of chain plates are hinged together, shifting forks with equal separation distances are arranged on both ends of each chain plate. The shifting forks are engaged with a tooth surface of gear teeth of a driving sprocket and a driven sprocket. The utility model has the advantages of simple and compact structure, low cost, low energy consumption, long service life, and convenient maintenance.

Description

A kind of carrier bar feedway

The utility model relates to a kind of carrier bar feedway.

The open transmitting bulk material device of metallurgical, the existing use of building material industry can be divided into two kinds of non-metal belt conveyor and metal belts according to the material of belt conveyor.The non-metal belt conveyor generally adopts balata belt, so owing to can not high temperature resistantly can only transmit the normal temperature loose unpacked material, as: sand, stone, cement etc.For the transmission that is fit to building materials metallurgy industry high-temperature material has produced metal carrier bar feedway, it adopts the chain-type flight conveyor usually, and this structure is by slick and sly chain captive joint metal carrier bar, by a large amount of bogie wheel supporting carrier bar motions.This structure exists that bogie wheel is many, complex structure, from great, power consumption is high, shortcomings such as cost is high, fault is many, maintenance cost height.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, compactness, and cost is low, and energy consumption is low, long service life, the carrier bar feedway of being convenient to safeguard.

The purpose of this utility model realizes by following technical proposals:

The carrier bar feedway comprises frame, drive part, running part, flight conveyor, carrying roller, running part has and cooperates drive sprocket and the driven sprocket that this belt conveyor is back and forth transmitted with flight conveyor, its technical scheme is that described flight conveyor is joined end to end by a plurality of carrier bars and is hinged together respectively, each carrier bar two ends is equipped with the shift fork that spacing equates, this shift fork is meshed with the gear teeth flank of tooth of drive sprocket, driven sprocket.

In the technique scheme, a plurality of carrier bars join end to end and are hinged together by bearing pin, short tube respectively, short tube is fixed in below each carrier bar the both sides along the carrier bar sense of motion, bearing pin inserts in the short tube on adjacent two carrier bars, the spacings of arbitrarily adjacent two row's short tubes equate, shift fork is the free end of the short tube that stretches out from the carrier bar two ends.One of them carrier bar two ends of adjacent two carrier bars also can be connected with backplate, and backplate is hinged with the free end of the short tube that is connected these adjacent two carrier bars.

The utility model is because flight conveyor is joined end to end by a plurality of carrier bars and is hinged together respectively, and each carrier bar two ends is equipped with the shift fork that spacing equates, this shift fork is meshed with the gear teeth flank of tooth of drive sprocket, driven sprocket.Like this, it is simple in structure, compactness, and cost is low, and energy consumption is low, is convenient to safeguard long service life.

The utility model is described in further detail below in conjunction with embodiment:

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

Fig. 2 is the front view of carrier bar (a wherein part).

Fig. 3 is the birds-eye view of carrier bar (a wherein part).

Fig. 4 is along the part sectional view of A-A line among Fig. 3.

Fig. 5 is the structural representation that drive sprocket cooperates with the shift fork transmission in the utility model.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model comprises frame 10, drive part 7, running part, flight conveyor 3, carrying roller 4 and 8, frame 10 adopts angle steel and channel-section steel to form truss structure, and the drive part 7 that is installed on the frame has electrical motor and retarder.Running part except that having drive sprocket 2 and driven sprocket 9, the chain 5 that also has the sprocket wheel 1 coaxial, is installed on the sprocket wheel 6 on the reducer output shaft and cooperates with this two sprocket wheel 1 and 6 with drive sprocket.Driving and driven sprocket wheel 2 and 9 respectively is a pair of, is located at the both sides of flight conveyor 3 respectively.Drive sprocket 2, driven sprocket 9, sprocket wheel 1 are by frame 10 supportings.Carrying roller 4 and 8 rollers are located between the driving and driven sprocket wheel and are connected with frame respectively, and they are in order to supporting flight conveyor 3.Flight conveyor 3 is joined end to end by a plurality of measure-alike carrier bars 31 and is hinged together respectively, and carrier bar 31 adopts the metallic material that is fit to the high-temperature material transmission to make.Above-mentioned pivotally attached structure is along the both sides welded metal short tube 34 of carrier bar sense of motion, in the short tube 34 that inserts on adjacent two carrier bars with bearing pin 32, with the carrier bar composition flight conveyor that connects together below carrier bar 31.The spacing of adjacent arbitrarily two row's short tubes 34 equates.The free end of the short tube 34 that stretches out from the carrier bar two ends is shift fork 34a, this shift fork 34a is meshed with the gear teeth flank of tooth of drive sprocket 2, driven sprocket 9, driving and driven sprocket wheel 2 and 9 wheel pitch of teeth equal the width between centers of adjacent two row's short tubes, thereby realize that sprocket teeth stirs shift fork and move.For strengthening the pulling strengrth of belt conveyor, prolong its service life, adjacent two carrier bars 31 one of them carrier bar two ends also can be connected with backplate 33, and backplate 33 is hinged with the free end (shift fork 34a) of the short tube 34 that is connected these adjacent two carrier bars.During the utility model work, the output shaft of retarder drives sprocket wheel 6 rotations, sprocket wheel 6 drives sprocket wheel 1 rotation by chain 5, because sprocket wheel 1 and drive sprocket are coaxial, so drive sprocket 2 rotations, the gear teeth of drive sprocket are stirred shift fork 34a and are moved, make flight conveyor 3 along driving and driven sprocket wheel crank motion, when flight conveyor process driven sprocket, shift fork 34a stirs the gear teeth of driven sprocket, makes driven sprocket 9 rotations.The utility model is particularly suitable for requiring to vibrate less occasion and uses.
