[0032] The user can install the sensor on the rotating cylinder and the arc slope 4 on the fixed cylinder according to actual needs. The other end of the sensor and the arc slope 4 can be in sliding contact or rolling contact.

[0033] A grain unloading drum position measuring device provided by an embodiment of the utility model mainly changes the rotational position of the grain unloading drum, and utilizes the slope (arc-shaped slope 4) on the rotating drum 1 to drive the rocker arm on the angle sensor (sensor 6) to rotate, so that the voltage value output by the angle sensor can directly feedback the actual position of the grain unloading drum.
