Liquid and solid quantitative feeding device

The utility model relates to the field of feeding, in particular to a liquid and solid quantitative feeding device which comprises a feeding body, a motor is installed at the top end of the feeding body, a transmission shaft is fixedly installed on an output shaft of the motor, a first gear is fixedly installed outside the lower end of the transmission shaft, and a notch is formed in the right end of the lower end of the feeding body. A material control plate is movably mounted in the notch, a fixed block is fixedly mounted at the top end of the material control plate, a roller is movably mounted at the top end of the fixed block through a bearing, a rotating rod is movably mounted at the bottom end in the feeding main body through a bearing, and a cam is fixedly mounted outside the rotating rod; the middle of the cam is attached to the outer surface of the rolling wheel. The problem that quantitative discharging is inconvenient for the feeding main body is solved, the operation convenience of operators is im
