[0026] Working principle: The unloading trolley moves forward along the feeding direction to the unloading area, and the silo door opening rod contacts the swing hook, causing the swing hook to swing backward. At this time, the swing hook gradually disengages from the silo door locking hook, and the silo door is in an open state. Under the action of the control block, the opening angle of the silo door gradually increases, and the bulk materials are gradually discharged downward under the action of gravity; the opening speed of the silo door can be controlled by controlling the slope design of the block to meet the unloading requirements of bulk materials of different sizes; when the unloading is completed, the unloading trolley moves backward and gradually leaves the unloading area, and the silo door gradually closes automatically under the action of the control block. At this time, the silo door striker also gradually disengages from the swing hook. When the silo door is completely closed, the swing hook is reset to engage with the locking hook under the action of the tension spring, thereby locking the silo door.
