要望がある。 The above-mentioned lifting treatment device combs up the stem culms planted in the field in advance using the stem culm lifting device, thereby removing the fallen stems that are difficult to catch with the claws of the stem culm lifting device. It is designed to be able to pull up the stem culm well, and by making it possible to change the position of one combing device to different positions depending on the working conditions, it A state in which the culm group to be reaped at a certain point and a group of uncut culms located on the side of the machine body are separated from the entanglement, and a state in which the culm group to be reaped is pulled up and the device is moved to the desired position. Although the device is designed to perform better lifting processing while being properly used in a posture that allows the transfer action to be performed properly, there are the following demands.

た。 In other words, when the stem culm combing device is positioned at the lateral end position to exert the effect of separating the entangled stem culms, a stem culm guide that protrudes laterally toward the rear is provided, There is a desire to press and guide a group of stem culms to be cut toward the outer side of the machine body, or to press and guide a group of stem culms to be harvested toward the inner side of the machine body. but,
When the stem culm combing device is positioned at a horizontally intermediate position to perform the action of pulling up the stem culm group and delivering it to the device, if the stem culm guide tool is provided, this guide tool will move to the rear of the stem culm group. This creates unnecessary resistance to the movement of the stems and causes problems such as disturbing the posture of the stems and culms. For this reason, in the past, it was carried out without providing a stem culm guide, so when the stem culm combing device was positioned at the lateral end position, it was not possible to fully exert the desired lifting action. I was afraid.

る。 The present invention has been made with the above-mentioned circumstances in mind, and includes a lifting device for a reaping and harvesting machine having the above-mentioned structure, in which a stem culm guiding posture that protrudes laterally toward the rear of the combing device is provided. The combing device is characterized in that a stem culm guide is attached to the side wall of the combing device so as to be switchable between the storage position and the storage position in which the entire device is brought close to the side wall of the combing device.

るに至つた。 That is, since the stem culm guide device that can change its posture is attached to the combing device, when the combing device is positioned at the lateral end position, the stem culm guide device must be switched to the stem culm guiding posture. , by exerting the effect of pressing and guiding the group of uncut stem culms outward to the side of the machine body or the effect of pressing and guiding the group of stem culms to be harvested inward to the side of the machine body, and fully exerting the desired raising effect. On the other hand, when the combing device is located at a laterally intermediate position, it is possible to avoid unnecessary resistance to the movement of the stem culm group by switching the stem culm guide to the retracted position. By satisfying the above-mentioned requirements, we have finally achieved a lifting device for a reaping and harvesting machine that can be used more favorably as a whole.
