Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to lift up and transfer heading vegetables such as cabbage and Chinese cabbage that are being set up by lifting and transferring with a holding and transferring device. The present invention relates to a vegetable harvester configured for cutting.

[0002]

2. Description of the Related Art A transfer device for holding headed vegetables such as cabbage and Chinese cabbage planted in a field and lifting them while transferring them obliquely rearward and upward, and a stem portion or an onion from a head part of cabbage or the like during the transfer. There is known a vegetable harvesting machine in which a self-propelled vehicle body is equipped with a harvesting working unit including a cutting tool for separating leaves (for example, Jitsukai Sho 50-12255).
No. 6 publication).

[0003]

A pull-out transfer device in a conventional vegetable harvester includes a pair of left and right screws for holding and transferring the stem roots of headed vegetables, and a transfer belt for abutting the crown of the headed part. When the device is tilted at a steep angle, the posture of the headed vegetable becomes unstable during the transfer, and the product is likely to fall down.

Therefore, conventionally, the harvesting and transferring device is provided at a gentle angle and inclined rearward to prevent the heading vegetables from falling, while the harvesting work section is provided with the gently lifting and withdrawing and transporting device. Was installed on the lateral outer side portion of the body of the crawler vehicle so as not to increase the front-rear length of the harvester. Since the harvesting work section and the harvesting work section move laterally at different positions, there is an inconvenience that it is not possible to suddenly enter the middle part of the field where the heading vegetables are planted and perform the harvesting work. In addition, since the transfer end portion of the pulling-out transfer device, that is, the portion for taking out the headed vegetables is located at the rear of the vehicle body and is far from the operating section, the operator cannot cooperate in the work for taking out the headed vegetables. It was

Further, in the conventional lifting and transferring device in the vegetable harvesting machine, the transferring belt for holding the heading vegetables in cooperation with the pair of right and left screws is provided with the central part of the upper surface of the heading part.
That is, since the head portion of the headed vegetable is pressed against the head portion of the headed vegetable, there is a problem that the head portion of the headed vegetable is easily damaged and the commercial value is lowered.

[0006]
