Detailed Description of the Invention The present invention provides a transmission device for transmitting rotational power to a grain lifting machine in a grain lifting machine for discharging grains, which is installed in a grain tank mounted on the body of a harvesting machine. This is related to improvements.

The grain lifting machine, which is installed on the grain tank mounted on the body of the harvester to take out the grain stored in the tank to outside 1a, is supported by the grain tank when assembled, but the lifting v4iA is done manually. In order to transmit rotational power to the shaft, the transmission device is installed between the human power shaft and the power extraction shaft provided on the body of the harvesting machine, and the intermediate transmission section, which is constructed separately from the grain lifting machine, is connected to the harvesting pus. Assembled into the fuselage, the input shaft of this intermediate conduction part is conducted to the power take-off shaft provided on the fuselage, and the output shaft of the intermediate conduction part is raised! It is constructed by combining the human power axis of tll and lx 'j'J.

For this reason, the human-powered shaft of the grain lifting machine assembled into the grain tank,
The power take-off 11ζ11 installed on the fuselage is mounted on the fuselage.
