A multifunctional material metering device for
engineering cost comprises a box body, and supporting components which are evenly distributed are arranged on the periphery of the bottom of the box body; the top wall and the bottom wall of the box body are respectively provided with two feed ports and a
discharge port; the two discharging hoppers are arranged in the inner cavity of the box body and correspond to the two feeding ports one to one, and a smashing component is arranged in one discharging hopper and used for smashing large materials in advance; the metering component is arranged in the inner cavity of the box body, and the metering component is used for temporarily storing and weighing materials; the feeding end of the metering component is in
butt joint with outlets of the two discharging hoppers, and the discharging end of the metering component is provided with a first
electromagnetic valve and is in
butt joint with the discharging port. And the buffer component is arranged in the inner cavity of the box body and connected between the metering component and the bottom of the inner cavity of the box body, and the buffer component is used for eliminating the material
impact force. The material metering device can solve the problems that when an existing material metering device for
engineering cost is used for weighing materials, the material
impact force on a metering cylinder is large, parts such as a weighing sensor in the metering cylinder can be damaged, gaps between material blocks are large due to the fact that part of large materials are poured into the metering cylinder, the materials contained in the metering cylinder are few when the metering cylinder is used for weighing the materials each time, and the weighing efficiency is high. And the weighing efficiency is influenced.
