Small material hoisting and discharging device

The utility model belongs to the technical field of electromechanical equipment, and in particular relates to a small material hoisting and discharging device used for a magnetic material grinding machine. The small material hoisting and discharging device mainly comprises a conveying main board, a rodless cylinder, a bearing cam mechanism, a hopper and a photoelectric sensing device, wherein the rodless cylinder and the bearing cam mechanism are assembled on the conveying main board; and a transmission running slot and a material turnover hole are formed on the conveying main board. The small material hoisting and discharging device can realize timing in a short distance, quantitatively conveys and discharges materials, and gives an alarm and shuts down when materials are enough or deficient. In conveying materials, the device is not influenced by ON/OFF of the grinding machine, namely, when a first batch of products is grinded, a second batch of products can be grinded, semi-automation control and timed and quantitive hoisting are realized.
