Dynamic device is connected with the revolving support simultaneously by a synchronous gear transmission device.
Further, a diameter of 4.5m to 6m of the impeller body.
Further, each drive device includes a motor and the deceleration with driving motor output shaft drive connection
Machine, the rated power of the motor is 30kw to 40kw.
Further, the motor connects a frequency converter simultaneously.
Further, a pair of drive devices are arranged symmetrically using the gyroaxis of revolving support as symmetry axis.
Further, the synchronous gear transmission device includes：It is respectively arranged at the one of the output end of a pair of drive devices
To little gear；The gear wheel engaged simultaneously with little gear, the gear wheel are connected with revolving support.
Further, the gear wheel and the gearratio of little gear are 1:3 to 1:7.
Further, in addition to below the impeller unit, it is symmetrically arranged in the coal groove of the revolving support both sides.
By using above-mentioned technical proposal, drain batcher of the present utility model is the realization of square coal receiving bunker in equipment
Aspect provides the foundation, and is achieved plurality of advantages of the square coal receiving bunker in work progress.And by setting synchronous drive
Dynamic, transmission mechanism can balance feeder stress, the stress of coal conveyer beltses below feeder thus be balanced, to improve equipment
Stability.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clear, complete description.
In one embodiment, in square coal receiving bunker as shown in Figure 1, the coal receiving bunker uses slot type coal hopper coal receiving bunker structure,
Its bottom is square arrangement, bottom arrangement ribbon conveyer, and drain feeder provided by the utility model is i.e. defeated positioned at belt
Send above machine.
As shown in Fig. 2 (part universal architecture has been done suitable drain feeder with the application core purport onrelevant structure
When omission) mainly include：Impeller unit 1, below impeller unit 1, it is symmetrically arranged in the coal groove of impeller unit axis both sides
2, the walking of bottom and supporting construction 3, wherein, walking and supporting construction refer to the corresponding position of paddle coal feeder in the prior art
Structure is put, will not be repeated here.The both sides of coal groove 2 are arranged, so as to realize both sides blanking, two-way group of coal of impeller.
As shown in figure 3, impeller unit mainly includes, and impeller body 11, the drive component that driving impeller body 11 rotates；
With reference to Fig. 4 and Fig. 5, drive component specifically includes：The coaxially connected single-revolution support 12 with impeller body 11；A pair of drives
Dynamic device 1301；A pair of drive devices 1301 are connected with revolving support 12 simultaneously by a synchronous gear transmission device.And
