Description

  The present invention relates to a crop harvesting machine for harvesting root vegetables such as radish, strains, ginger and carrot carrots.

A crop harvesting machine for harvesting root vegetables planted in a field is described in Patent Document 1 and Patent Document 2 below.
Patent Document 1 discloses a self-propelled harvesting auxiliary working machine that includes a conveyor that conveys harvested radishes, and a foliage removing device that cuts and removes the foliage portions of the radishes during conveyance.

  As a result, if the worker places the radish dug from the field on the conveyor, the radish is removed in the middle of the transportation, and the leaves and leaves are removed, and the radish is put into the storage container provided in the harvesting auxiliary work machine. The work becomes easy, and it is not necessary for the operator to manually remove the stems and leaves of the radish, thereby saving labor.

  Patent Document 2 discloses a drawing assistance operation in which an operator does not have to perform a drawing operation that requires force by holding and pulling a radish stem and leaf portion that is vegetated in the field and leaving the radish dropped on a drawing trace in the field. The machine is listed.
