The feed hopper is installed in the box body, and the inner cavity of the box body is equipped with a limiting device for limiting the food from falling out of the bottom opening of the feed hopper. The metering device includes a weighing device and a pushing assembly, a support plate is horizontally provided in the inner cavity of the box body, a groove is provided on the top of the support plate, the weighing device is adapted to be installed in the groove, a loading plate is fixedly installed on the top of the weighing device, and the loading plate is directly below the bottom opening of the feed hopper", and the technical deficiency of "obtaining the weight of food by manual weighing with a balance is more troublesome, and when the amount of food is large, the manual operation process is also more troublesome" is proposed.
