As shown in figures 1-3, the grain blocking door with the upward-turning grain outlet door plate is of a side-by-side door structure, when two door leaves 1 are combined together, an arc or triangle structure protruding into a granary is formed, the bottom of each door leaf 1 is provided with the grain outlet door plate 2, the top of each grain outlet door plate 2 is hinged with the bottom of each door leaf 1 through a hinge 3, an electric telescopic rod 4 arranged along the vertical direction is hinged between the middle of each grain outlet door plate 2 and the bottom of each door leaf 1, and a locking mechanism 5 is connected between the two grain outlet door plates 2. Since the grains can flow out rapidly when the grain outlet door plate 2 is opened, the grain outlet door plate 2 is inconvenient to be opened manually by a person, and the grain outlet door plate 2 is required to be realized by adopting remote-control electric equipment, such as an electric hydraulic rod, an electric cylinder or a screw motor. The locking mechanism 5 has the functions of supporting and fixing the grain outlet door plate 2, ensuring the structural strength of the grain outlet door plate 2 and avoiding the random opening of the grain outlet door plate 2.

The specific working process of the utility model is as follows: when the grain outlet door plate 2 is in a closed state, the electric telescopic rod 4 is in an extension state; when the grain outlet door plate 2 needs to be opened, the electric telescopic rod 4 contracts to drive the grain outlet door plate 2 to turn upwards. Because the two door leaves 1 form an arc-shaped or triangle-shaped structure when in a closed state, after the two grain outlet door plates 2 are connected together by the locking mechanism 5, the two grain outlet door plates 2 cannot be turned upwards, so that the grain outlet door plates 2 are locked. When the grain discharging door plate 2 is ready to be opened, the locking mechanism 5 is required to be removed firstly, then the electric telescopic rod 4 is utilized to drive the grain discharging door plate 2 to overturn upwards, grains in the bin can flow automatically and flow out from the bottom of the grain blocking door safely under the action of gravity and pressure, the grain discharging speed can be controlled by controlling the opening angle of the grain discharging door plate 2 during the grain discharging process, and the discharged grains can be collected and cleaned by utilizing equipment such as a grain scraper and the like, so that the pressure in the grain blocking door is rapidly reduced, the grain blocking door is opened more quickly, the grain discharging efficiency is improved, and the safety of grain discharging is ensured.
