Blanking metering device capable of achieving accurate feeding

The invention relates to the technical field of agricultural equipment, and discloses a discharging metering device capable of achieving accurate feeding, which comprises a feeding trough, a supporting plate is fixed at the bottom of the feeding trough, a supporting frame is slidably connected to the outer side of the supporting plate, a fixing frame is connected to one side of the top of the feeding trough, a storage tank is fixed at the top of the fixing frame, and a feeding port is formed in the top of the storage tank. When animals are fed, the PLC transmits a signal to the electric push rod, the push rod end of the electric push rod extends out, the transverse plate pushes the first baffle and the push plate to move upwards at the same time, feed in the storage tank enters the feeding trough through the discharge pipe, and the feed in the storage tank enters the feeding trough through the discharge pipe. When the weight reaches the weight that the animals need to eat each time, the push rod end of the el
