Beneficial effect of the present invention is: (1), the storehouse by feeder bin bottom retransmit sensor the heavy signal in real-time storehouse is sent into weighing instrument, weighing instrument passes to upstream equipment frequency converter by conditioning signal after comparing according to the heavy signal in storehouse and setting value blanking velocity is controlled and adjusted, and guarantees that the inventory in feeder feed bin is relatively stable; (2), by speed sensor and the LOAD CELLS of feeder, respectively speed signal, weighing-up wave are transferred to weighing instrument, weighing instrument output regulation signal regulates to feeder frequency converter, guarantees actual feeding coal and sets feeding coal and match; (3), the present invention reduced artificial input, improved the economic benefit of enterprise.
 
Accompanying drawing explanation
Fig. 1 is the dual Weighing feeder structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
In figure of the present invention: weigh roller, 8-LOAD CELLS, 9-speed sensor, 10-carrying roller, 11-scale frame, 12-storehouse of 1-frame, 2-feed bin, 3-drive motor, 4-load-transfer device, 5-great wheel, 6-tail wheel, 7-retransmits sensor, 13-overload prevention cover, 14-Dust guard cover, 15-and adjust roller, 16-tensioner, 17-belt scraper, 18-weighing instrument, 19-feeder frequency converter, 20-upstream equipment frequency converter.
As shown in Figure 1, in the dual Weighing feeder of the present invention, great wheel 5 is arranged on the rear end of frame 1, and great wheel 5 is connected whole feeder is driven with drive motor 3; Tail wheel 6 is arranged on the front end of frame 1, and speed sensor 9 is arranged on tail wheel 6 and is connected with weighing instrument 18.The outside of great wheel 5 and tail wheel 6 is provided with load-transfer device 4, and load-transfer device adopts shirt rim belt; Tail wheel 6 connects tensioner 16, for regulating the tensile force of load-transfer device 4.Before 2 adjustment rollers 15 are arranged on respectively great wheel 5 and after tail wheel 6, adjust roller 15 and can freely finely tune height up and down, the impact of weighing to reduce the tensile force of load-transfer device 4; At 2, adjust between roller 4 and 4 carrying rollers 13 are installed successively and weigh roller 7.Directly over 4 carrying rollers, 13 upper conveyor belts 6, feed bin 2 is installed, 4 carrying rollers 13 are seated on scale frame 11 simultaneously, the below of scale frame 11 is provided with storehouse and retransmits sensor 12, storehouse retransmits sensor 12 and is connected with weighing instrument 18, storehouse retransmits sensor 12 outsides and is provided with overload prevention cover 13, and overload prevention cover 13 outsides are provided with Dust guard cover 14.The weigh below of roller 7 arranges LOAD CELLS 8, and LOAD CELLS 8 is connected with weighing instrument 18, and LOAD CELLS 8 outsides are provided with Dust guard cover 14.Belt scraper 17 is installed in the load-transfer device bottom of frame 3 rear end, and belt scraper 17 is adjustable with load-transfer device 6 distances, to remove in time the residual object of load-transfer device 6.Weighing instrument 18 is connected with feeder frequency converter 19, upstream equipment frequency converter 20 respectively.
It is that the heavy signal in storehouse is sent into weighing instrument by the material in feeder feed bin that the present invention retransmits sensor by storehouse, weighing instrument passes to conditioning signal upstream equipment frequency converter after comparing according to the heavy signal in storehouse and setting value again the blanking velocity of upstream equipment is controlled, make the material in feeder feed bin remain on a metastable state, to prevent the phenomenons such as fracture, full material; LOAD CELLS measures on load-transfer device that the weight signal of material sends with speed sensor becomes the impulse singla of fixed proportion with load-transfer device speed, by weighing instrument conversion process, draw actual feeding coal, and after actual feeding coal is constantly contrasted with setting feeding coal, send conditioning signal and to feeder frequency converter, adjust the delivery speed of load-transfer device, make actual feeding coal meet setting feeding coal, thereby guarantee that Weighing feeder realizes accurate dosing.
During work, drive motor 3 drives great wheel 5 to drive tail wheel 6 and load-transfer device 4 to rotate, upstream equipment is transported to raw material in the feed bin 2 of dual Weighing feeder, the storehouse of feed bin 2 belows retransmits sensor 12 the heavy signal in real-time storehouse is transferred to weighing instrument 18 Treatment Analysis, when the heavy signal in storehouse that weighing instrument 18 obtains certainly and setting value there are differences, weighing instrument 18 sends conditioning signal and to upstream equipment frequency converter, the blanking velocity of upstream equipment is regulated and controled, thereby guarantees that the material in feeder feed bin is relatively stable; Material in feed bin 2 is transferred is with 4 drives to transport forward, through weighing roller 7 tops, weigh the LOAD CELLS 8 of roller 7 belows rapidly by weight signal, together with the speed signal recording with speed sensor 9, be transferred to weighing instrument 18 processing and draw actual feeding coal, and after actual feeding coal and setting feeding coal are contrasted, send conditioning signal to feeder frequency converter 19, adjust the delivery speed of load-transfer device 4, make actual feeding coal meet setting feeding coal.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
