Description

  The present invention relates to a root vegetable harvester that harvests root vegetables.

2. Description of the Related Art Conventionally, a self-propelled root vegetable harvesting machine that harvests root vegetables planted in a field while traveling in the field is known. Such a conventional root vegetable harvesting machine performs a series of operations such as extracting a root vegetable from the field, cutting off the stem and leaf portion of the root vegetable from the main root portion, and storing the main root portion of the root vegetable in a storage bag. For example, as described in Patent Document 1.
Moreover, the conventional root crop harvesting machine can adjust a cutting position (position which separates a foliage part and a main root part) by adjusting the vertical position of the foliage cutting device with respect to the shoulder aligner. Therefore, by adjusting the cutting position to a desired position in advance, the root vegetables stored in the storage bag are taken out from the storage bag again, and the cutting position is adjusted again manually (for example, the operator can use a cutter knife or the like). The remaining foliage is cut off from the main root).

Here, depending on the shape of the field or the environment surrounding the field, there is a part in the field where the root vegetables cannot be extracted by a conventional root vegetable harvesting machine. For example, when there are walls, irrigation channels, etc. around the field, it is necessary for the conventional root vegetable harvester to turn (change the direction of travel) in the field with the “position where the pulling and conveying device is lifted with respect to the traveling device”. is there. In addition, even when entering the field through a downhill from a farm road or the like adjacent to the field, in order to prevent the pulling and conveying device etc. from sticking into the field, the “position in which the drawing and conveying device is lifted with respect to the traveling device” It is necessary to drive at. The conventional root crop harvester cannot harvest the root crops planted in the portion running in such a posture.
Regarding the root vegetables planted in the portion where the root vegetables cannot be extracted by the conventional root vegetable harvesting machine, the operator manually pulls them out from the field and inserts them into the pulling and conveying device.

  However, a raising device and a plow are arranged in front and below the pulling and conveying device, respectively, and the operator's hand or root vegetables come into contact with them, so that it is difficult to insert the root vegetables into the pulling and conveying device. Another possible method is for the operator to manually adjust the "cutting position of the root vegetable manually pulled out" to the same position as the "cutting position of the root vegetable pulled out by the conventional root vegetable harvesting machine". However, this method is complicated.
