Anti-blocking rice storage bin

The utility model relates to the technical field of rice storage, and discloses an anti-blocking rice storage bin which comprises a storage tank, a hydraulic cylinder and a positioning shaft rod. A feeding port is formed in the top end of the storage tank, the positioning shaft rod is installed in the storage tank, the top end of the positioning shaft rod extends out of the top end of the storage tank, the hydraulic cylinder is installed at the top end of the storage tank through a support, and the moving end of the hydraulic cylinder is connected with the top end of the positioning shaft rod. According to the anti-blocking rice storage bin, the hydraulic cylinder drives the positioning shaft rod to move up and down in the storage tank in a small range, when rice is extruded in the storage tank to form yield stress to cause blocking, the yield stress between the rice can be broken through up-down floating of the positioning shaft rod, and the flowing state of the rice can be recovered; a temperature sensor is
