In order better to understand and to implement the technical solution of the utility model, provide embodiment more of the present utility model at this, these embodiments, in order better to explain technical scheme described in the utility model, do not form any form restriction of the present utility model.
The lime production mixing system of weighing, comprise green stone feed bin, coke feed bin, on green stone feed bin and coke feed bin, be provided with oscillating feeder, oscillating feeder is arranged with weighing device, weighing device is arranged with middle hopper, be arranged with batch mixing belt at the middle hopper of green stone, the middle hopper of coke is arranged with coke belt, described coke belt is positioned at the top of batch mixing belt, the near-end of coke belt and batch mixing belt partly overlaps at above-below direction, described oscillating feeder adopts PLC to control, described oscillating feeder is provided with frequency-converting control device, described green stone middle hopper is to the little 1.2m of distance of batch mixing belt, the middle hopper of described coke is less than 1.2m to coke belt distance, described coke belt and the above-below direction of batch mixing belt distance are less than 1m.More specifically as shown in drawings, in accompanying drawing, each mark is depicted as embodiment: 1-1: oscillating feeder a, 1-2: oscillating feeder b, 2-1: green stone Weighing system, 2-2: coke Weighing system, 3:PLC, 4: batch mixing belt, 5: coke belt, 6: truck, 7: weighing hopper combination, 8: bracket, 9: LOAD CELLS, 10: pneumatic means, 11: middle bucket support, the lime production mixing system of weighing, comprise green stone feed bin, coke feed bin, on green stone feed bin and coke feed bin, be provided with oscillating feeder, 1-1 is the oscillating feeder a arranging on green stone feed bin, oscillating feeder a is arranged with green stone weighing device, 2-1 is green stone weighing system, green stone weighing device is arranged in weighing system, green stone weighing device is arranged with middle hopper, 11 supports that are depicted as middle hopper in Fig. 2, middle hopper is arranged on middle hopper support, middle hopper at green stone weighing system 2-1 is arranged with batch mixing belt 4, 1-2 is depicted as the oscillating feeder b1-2 arranging on coke feed bin, oscillating feeder a is arranged with green stone weighing device, 2-2 is coke weighing system, coke weighing system is identical with green stone weighing system, on the middle hopper support of coke weighing system, be provided with middle hopper, the middle hopper of coke is arranged with
