Claims

[Scope of utility model registration request]

A vertical conveyance cheno 9 of the reaping conveyance section A that supplies grain culms to the foot chain 12 of the threshing section C is movably attached to the machine body 2, and a handling depth adjustment lever 17 is attached to the vertical conveyance cheno 9.
By operating this adjustment lever 17, the receiving position of the grain culm supplied to the foot chain 12 can be adjusted, and the handling depth of the grain culm with respect to the handling barrel 14 can be adjusted. is configured to be freely engageable and detachable from the screw conveyor 20 rotated by a forward and reverse rotation motor M, and the rotation of this forward and reverse rotation motor M is arranged at a location where the grain culm reaches the supply port 11 at the front end of the threshing section C. The handling depth is automatically controlled based on the handling depth detection result of the handling depth detection device 27, and by engaging and disengaging the adjustment lever 17 from the screw conveyor 20, automatic control/manual control of handling depth adjustment is performed. The handling depth adjustment device for a combine harvester is capable of switching, in which a guide plate 33 having a guide opening 33a for the adjustment lever 17 is provided above the screw conveyor 20, and the adjustment lever 17- is connected to the screw A biasing mechanism 34 is provided inside the guide plate 33 to constantly bias the adjusting lever 17 in the direction of engagement with the conveyor 20. A safety guard 3 that moves lightly so as to automatically close the opening 33a of the guide plate 33 when biased and moved to the matching position.
5. A handling depth adjustment device for a combine harvester, characterized in that: 5 are interlocked and connected.
