Technical Field
The invention relates to the technical field of material metering, in particular to a novel material metering device.
Background
The aggregate (including sand and stone), powder (including cement, fly ash, mineral powder and the like) and liquid (including water, admixture and the like) of the existing mixing plant are mostly measured in the following ways: a plurality of weighing sensors at fixed positions are arranged on a weighing hopper bracket, and then the weighing hopper is arranged on the weighing sensors for weighing.
Wherein weighing sensor's rigidity, because the difference of concrete ratio, the weight of weighing at every turn is also different, causes to weigh material focus also different, and the shape of weighing hopper is general all irregular moreover, so stress that leads to a plurality of weighing sensor when weighing is inhomogeneous. According to the weighing principle of the existing weighing sensors, the stress of the weighing sensors is more uniform, the weighing precision is higher, but the positions of the existing weighing sensors are fixed, the stress of the weighing sensors is not uniform, the weighing precision is poorer, and the actual material metering accuracy is deviated.
