Reaping and harvesting, wherein a stem culm combing device that moves a stop claw upward from near the ground at a front location of the pulling device group is configured to be switchable between a lateral end position and a lateral intermediate position of the pulling device group. The purpose of the present invention is to facilitate and speedily replace the stem culm combing device with respect to the lifting device of the machine.

The above-mentioned lifting treatment device combs up the stem culms planted in the field in advance with a combing device equipped with claws in a forward-protruding position. The system is designed to be able to effectively pull up stem culms that are in a collapsed state, which is difficult to lock, and moreover, the stem culm combing device is placed at the lateral end position and the lateral intermediate position of the group of lifting devices. By making it replaceable, a state is achieved in which an effect is exerted to separate the entanglement between the group of stem culms to be reaped located at a position corresponding to the front of the machine body and the group of stem culms that are not cut, located at the side part of the machine body. , a state in which the group of stem culms to be harvested can be properly pulled up in a desired posture and delivered to the device can be used depending on the working conditions, and even better lifting processing can be performed. However, it has become difficult to easily and quickly move the stem culm combing device to a different position.

In other words, in order to support the combing device, it is necessary to support the combing device at two points, its upper end and its lower end, to support the combing device as a whole. The upper end of the combing device can be supported in a manner that allows for easy and quick replacement operations by using a guide support mechanism that is provided so as to bypass the tips of the stalks to be harvested. , its lower end must be fixedly connected to fixed frames provided at different positions in a state that allows passage of the group of reaped stems and culms. However, the work of fixing and connecting the lower end of the combing device, which will be located below the machine, and the fixed frame using bolts, etc. is difficult.
Because the worker has to perform the work in a bent-down position, the work tends to be troublesome and troublesome, and as a result, the entire replacement work is difficult to perform easily and quickly. .

The present invention has been made with the above-mentioned circumstances in mind, and in a lifting device for a reaping and harvesting machine having the above-mentioned structure, when the combing device is supported at different positions, the upper end thereof is supported in a lateral direction. A mechanism is provided for guiding and supporting the device in a movable and adjustable manner, and a mechanism is provided for fixing and locking the lower end of the device to a fixing frame provided at different positions, and the fixing lock mechanism can be switched between a locked state and an unlocked state. It is characterized in that a switching operation tool is provided at the upper end of the combing device.

That is, the upper end of the combing device is supported using a guide support mechanism in a manner that allows easy and quick replacement operations, and the lower end of the combing device is provided at the top end of the combing device for easy handling. The device uses a fixed lock mechanism that can be switched between a locked state and an unlocked state using a suitable operating tool, and is fixedly supported by fixed frames provided at different positions. This solves the above-mentioned problem in which the work of fixedly connecting the part and the fixed frame is complicated, and it becomes possible to perform the entire replacement work easily and quickly. As a result, we have achieved a lifting device for a reaping harvester that can be used more conveniently as a whole.
