Description

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

  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 root vegetable harvesting machine has a harvesting part arranged on one side of the traveling machine body to extract the root vegetable from the field, cut the main root part of the root vegetable from the foliage part, and transport the obtained main root part by a conveyor. A series of operations of storing in a storage container arranged at the downstream end is performed.

  Further, the main root portion conveyed on the conveyor is visually confirmed by an auxiliary worker different from the worker who operates the root vegetable harvester.

  Then, the auxiliary worker replaces the empty storage container when a predetermined amount of the harvest is stored in the storage container, and the storage container storing the harvest is placed on the other side of the traveling machine body. Work to move the part.

  In this way, the auxiliary worker assists in the harvesting work, and in particular, in the recently known root vegetable harvesting machine, in order to eliminate the need for the auxiliary worker to walk in the field as the root vegetable harvesting machine progresses, There is also a structure in which an auxiliary worker's seat is provided on the airframe so that it can be visually confirmed while seated (see, for example, Patent Document 1).

JP 2012-231697 A

  However, in the conventional root vegetable harvesting machine that enables an auxiliary worker to board, the auxiliary worker is seated on a chair placed on the mounting portion and checks the harvest, so the auxiliary worker himself There is a problem that a blind spot is created, and the storage state of a part of the storage container placed on the placement part cannot be sufficiently confirmed.

  Further, when the root vegetables harvested from the storage container placed on the placement unit spills out while traveling in the field, it is difficult to quickly get off and respond.

  The present invention has been made in view of such circumstances, and allows the harvesting unit, the relay conveyance unit, and the mounting unit to be visually recognized, and can be quickly dismounted and boarded. Provide root crop harvesting machine.

In order to solve the above-mentioned conventional problems, in the root vegetable harvesting machine according to claim 1, a harvesting part for transferring the root vegetable crops in the field to the rear while pulling out the root vegetable crops is arranged on one side of the traveling machine body that is capable of self-running. On the other hand, on the other side of the aircraft, there is a placement part that stores and places the harvested root vegetable crops in the container, and the harvested root vegetable crops are relayed between the harvesting part and the placement part. In the root crop harvesting machine with the relay transport section to transport,
The placement unit is disposed close to the terminal end of the relay transfer unit and receives the storage container, the first half part formed by extending forward from the storage container reception body, and the storage container reception A second half mounting body formed by extending backward from the body,
The container receiving body is provided with a sorting conveyor whose transport direction can be switched between the front and rear, and the container received in the container receiving body is moved to the first half mounting body side or the second half mounting body side by the sorting conveyor. Transportable and none,
