Abstract
The utility model relates to a powder-weighing controller used in the asphalt-mixing device of a pavement engineering machine. The power-weighing controller includes a weighing hopper, and a high-throughput rough-weighing screw conveyer and a low-throughput accurate-weighing screw conveyer are arranged over the inlet of the weighing hopper. By applying the big and small screw conveyers to feed materials, the powder-weighing controller can not only ensure the feeding speed and shorten the weighing period but also ensure the final weighing precision by means of the coordinate operation of the two screw conveyers in different time periods.
Description
Technical field
The utility model relates to a kind of powder metering control that is used for field of road engineering machinery pitch mixing mixing plant.
Background technology
In existing asphalt mixing plant, the flow of powder is controlled by following apparatus: promptly, before powder enters weighing hopper, by conveying worm control powder flow, the size of total amount was controlled with the time, because the discharge value of single conveying worm is certain, the low precision strain capacity is relatively poor, and mixing plant has requirement to metering cycle and precision, this structure can not the very back good requirement of satisfying system, cause the powder weight inaccuracy in the weighing hopper, the error effect of this weight the degree of accuracy of weighing and proportioning, caused the waste of material also to influence the quality of asphalt concrete pavement.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can shorten metering cycle, has the powder metering control of higher weighing precision simultaneously.
Powder metering control of the present utility model includes a weighing hopper, is provided with a bigger thick title conveying worm and the less essence of discharge value of discharge value and claims conveying worm above the weighing hopper inlet.
The utility model adopts small one and large one two conveying worm chargings, both can guarantee charging rate, shorten metering cycle, also can guarantee final measuring accuracy in the co-ordination of different time sections by two conveying worms simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, in this powder metering control, above the inlet of weighing hopper 1, be provided with a bigger thick title conveying worm 2 and the less essence of discharge value of discharge value and claim conveying worm 3.The utility model in the course of the work, weighing early stage, the thick conveying worm that claims kept operation, guaranteed feeding fast in weighing early stage; Weighing mid-term slightly claims conveying worm to close when powder amount during near required amount, and the smart conveying worm that claims keeps operation to carry out micro-feeding, thereby satisfies required precision.
Claims (1)
1, a kind of powder metering control includes a weighing hopper (1), it is characterized in that: be provided with a bigger thick title conveying worm (2) and the less essence of discharge value of discharge value and claim conveying worm (3) above the weighing hopper inlet.
