[0052] In combination with the drawings, the use process of the silo door locking device in the present embodiment is described as follows:

[0053] Firstly, pull the handle 50 to open the door body 100 to fill the material, and then rotate the door body 100 to the closed position after filling;

[0054] Secondly, rotate the rotary wheel 13 to make the first locking piece 211 and the second locking piece 212 respectively inserted into the corresponding limiting groove 221 through the rotating shaft 11 and the gear 12;

[0055] Finally, pass the limiting rod 40 through the limiting hole 131 and the plug hole 32 in sequence to limit the rotary wheel 13, so as to avoid the rotary wheel 13 from rotating to open the door body 100.

[0056] In summary, the silo door locking device in the present embodiment not only has simple structure and is convenient to open and close, but also can effectively prevent the door body 100 from being opened by itself, and has good locking effect.
