Claims

[Scope of utility model registration request]

■ At least one of the vertical conveyance device for supplying the harvested husk culm to the threshing feed chain at the start end of the reaped husk culm inheritance or the start end of the supply of the reaped husk culm to the feed chain is repositionably installed, and A swing operation lever is provided for changing the position of the vertical conveyance device, and by operating this lever, the receiving position of the culm supplied to the feed chain is adjusted, thereby adjusting the handling depth of the culm with respect to the handling barrel. The control lever is configured to be freely configured, and the control lever is removably engaged with a screw conveyor rotated by a forward/reverse motor with a substantially constant rotation speed, and in the engaged state, the control lever is automatically engaged based on the result of culm length detection by a sensor. A handling depth adjustment device for a combine, which is equipped with a control device that operates the motor in forward and reverse directions to maintain the handling depth within a set range, wherein the swinging angle of the lever per unit rotation of the screw conveyor is approximately constant. A handling depth adjusting device for a combine harvester, characterized in that the transfer pitch of the screw conveyor with respect to the lever is set so as to achieve the following. −
■ The screw conveyor is constructed by integrally molding a portion of the screw with which the operating lever engages and comes into contact with the outer circumferential portion of the shaft from synthetic resin, and a steel material is embedded inside the outer circumferential portion of the shaft. Scope of claim for utility model registration No. 0
The handling depth adjustment device described in Section.
