A. blending, by means of construction machinery and equipments such as loaders, the third belt feeder blending, by two or many angle of internal friction conveyers, in these blending modes, all be the speed control of volume or the belt feeder of the loader(-mounted) shovel by loader, guarantee the blending ratio of the coal of different heats, thereby make the blending ratio of coal inaccurate, influence the combustion performance of coal.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides a kind of batching metering device for coal blending device, so the accuracy rate height of coal blending ratio.
For achieving the above object, the technical scheme that the utility model is taked is: include on the output port that is arranged on feed bin and for delivery of coal and have load-transfer device band conveyor, be arranged on the band conveyor and the sensor that connects with the load-transfer device contact, be the controller of control band conveyor rotation speed signal with the sensor output signal.
The coal that contains different heats is put in the different feed bins, coal drops on the band conveyor from the output port of feed bin, sensor receives the coal weight signal on the band conveyor, change the velocity of rotation of band conveyor by controller, thereby within a certain period of time, the coal of predetermined weight is transported by band conveyor, owing to designed sensor and controller, weight by the measuring belt conveyer guarantees coal blending ratio, no longer by the volume of coal or the speed assurance coal blending ratio of carrying coal.Therefore coal is admixed the accuracy rate height of ratio.
The utility model has designed, band conveyor is set to include the motor load-transfer device, frame, swelling device, driving wheel and secondary driving wheel, driving wheel and secondary driving wheel are separately positioned on the frame and are set to and connect with the frame rotary type, load-transfer device is arranged on driving wheel and the secondary driving wheel, swelling device is arranged on the frame and is set to and connects with secondary driving wheel, driving wheel is set to connect with the output shaft of motor, sensor is arranged on the frame and the contact of sensor is set to connect with the load-transfer device contact, sensor is set to be connected with the controller input end, and the speed controller of motor is set to be connected with controller output end.
The utility model has designed, and load-transfer device is set to the rib belt.
The utility model has designed, and the turning cylinder of secondary driving wheel is set to connect with the frame sliding type, and swelling device is set to rotating screw bolt and is set to connect with the turning cylinder of secondary driving wheel.
Description of drawings
Fig. 1 is scheme drawing of the present utility model:
