Automatic feeding locomotive

The utility model relates to an automatic feeding locomotive, in particular to a feeding mechanism in the process of manufacturing and processing petroleum fracturing propping agents. The automatic feeding locomotive comprises a supporting frame, a power mechanism, a feeding mechanism, a driven shaft self-leveling mechanism, an electrical control system and a storage bin. The power mechanism, the feeding mechanism, the driven shaft self-leveling mechanism and the electrical control system are fixed on the supporting frame, and the storage bin is arranged above the feeding mechanism and fixed with the supporting frame. Rotating efficiency and locating accuracy are improved, and the automatic feeding locomotive is fast in response speed and long in service life. Swing of a driven shaft in appropriate range can be achieved, derailment caused by suspension of a monowheel due to uneven rails can be avoided, and a safety factor is improved. The storage bin can be used for feeding repeatedly after one-time charging, and feeding efficiency is high. The electrical control system is used for receiving preset control instructions in a wireless mode, a circuit control system is used for controlling a servo motor, and therefore automatic feeding can be achieved.
