The present invention relates to a device for opening and closing a grain storage tank for a combine, comprising: an opening and closing door (10) installed on a grain discharge port (401) formed on a grain storage tank for a combine (40) to be able to lift so as to open and close the grain discharge port (401); a discharge chute (20) installed on a lower part of the grain discharge port (401) to be able to rotate so as to guide grain discharged from the grain discharge port (401); and a driving part (30) which realizes interworking between opening and closing of the opening closing door (10) and rotation of the discharge chute (20) to be performed in sequence by rotation of a plate cam (303) rotated by an actuator (304). Accordingly, since malfunction of the opening and closing device may be prevented, grain is accurately be discharged and loss of grain and improving convenience of work can be prevented. |
