Further, a sensor protection device is fixedly arranged on the outer side of the weighing sensor.
Further, a material wall baffle is arranged on the top edge of the hopper.
Further, a movable vibration device is arranged on the hopper.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, four sensors are uniformly distributed at the lower part of the hopper, so that the aggregate bin can simultaneously bear aggregate storage and metering functions, and a traditional metering hopper or a metering belt is canceled, thereby compressing the whole height of the aggregate bin, meeting the requirement of direct loading of a loader, avoiding digging a pit or digging a loading slope, and avoiding the problems of high civil construction cost and large loading oil consumption of the loader;

Detailed Description
Example 1
Referring to fig. 1-2, the aggregate batching and metering device for a concrete mixing plant comprises a hopper 2 provided with a frame 3, wherein a material wall baffle 1 is arranged on the top edge of the hopper 2 and can be used for storing more sand aggregates; the bottom of the hopper 2 is provided with a discharging mechanism, the discharging mechanism comprises a revolving door 4 with two ends hinged on the hopper 2, the middle part of the discharging mechanism is hinged with the hopper 2 through an air cylinder 8, and the air cylinder 8 controls the opening and closing of the revolving door 4 to realize the discharge of sand aggregates from the hopper 2 for batching;
in order to avoid arching or sticking of inferior sand, a movable vibration device 7 is arranged on the hopper 2, so that arching and sticking of materials to the hopper wall can be effectively prevented;
the hopper 2 is connected with the frame 3 through four weighing sensors 5 which are uniformly distributed, so that the weighing function of sand aggregates is realized, namely, when ingredients are discharged, the weight reduction amount of the weighing sensors 5 for weighing the hopper 2 is the weight of the ingredients; the outside of each weighing sensor 5 is fixedly provided with a sensor protection device 6, so that the sensor is prevented from being hit by the dropping sand and stone in the feeding process. Because the weighing sensor 5 is directly arranged on the aggregate bin hopper 2, the aggregate bin has the aggregate storage and metering functions, and a traditional metering hopper or a traditional metering belt is omitted, so that the height of the overall structure of the aggregate bin is reduced, the requirement of direct loading of a loader is met, and a loading slope or a pit is not required to be formed by the loader;
