Description

  The present invention relates to a root vegetable harvester, and more particularly to a harvester for mainly harvesting radishes.

  A known radish harvester including the harvester disclosed in Patent Document 1 is a pulling and conveying mechanism that pulls out the radish from the field while sandwiching the foliage portion and cuts the foliage and delivers the radish to the collection conveyor (Patent Document) 1, a pulling and conveying device 3, a drawing processing unit 8, a foliage processing unit 9), and a foliage scratching mechanism installed in front of the drawing and conveying mechanism (pretreatment device 10 described in Patent Document 1, longitudinal rotation) There is known one provided with a type pulling mechanism 22 and a side turning type pulling mechanism 24).

  The reason why the radish harvester is equipped with a mechanism for raising the foliage is that the foliage that was standing upright in the morning will be in the daytime and the sun will become stronger, and it will spread laterally just before harvesting, This is because it becomes difficult for the pulling and conveying mechanism to pinch the proximal end portion of the foliage, so that the pulling and conveying mechanism can easily pinch the foliage by scratching the foliage spreading in the lateral direction in the vertical direction.

  By the way, in the field where the planted radish row continues several tens of meters in the front-rear direction, the field itself is often inclined, and in order to harvest the radish by operating the harvester in such a field, It is desirable that the foliage raising mechanism is always set at a position facing the base end of the foliage during the harvesting operation.

  The foliage scratching mechanism is set to an appropriate position immediately before the start of work, but when the harvester reaches an inclined ground during the work and the distance from the field surface is different from the setting time, the black laid on the field A film (a black film called a so-called multi-film) may be scratched together with the foliage. Since the black film is discarded after the harvesting operation is completed, the black film may be scraped by the scratching mechanism. However, the black film is scratched by the scratching mechanism and entangled with the pulling and conveying mechanism. If this happens, the subsequent harvesting operation will be hindered, and the entangled film must be removed. In addition, since the harvesting operation must be interrupted during the removal of the black film, care should be taken so that the film does not get entangled with the drawing / conveying mechanism or the like during the harvesting operation.

  The harvesting machine described in Patent Document 1 includes a vertical rotation raising mechanism 22 (corresponding to the second raking belts 230 and 240 of the present invention) and a horizontal rotation raising mechanism 24 (the present invention) constituting the pretreatment device 10. 1) and a handle means 25 for adjusting the positions of these mechanisms in the vertical direction (paragraph number 0022 in the specification). . However, in the apparatus described in Patent Document 1, the vertical rotation type and the horizontal rotation type raising mechanism 22 and 24 are integrally adjusted up and down by the operation of the handle means 25, and can correspond to an inclined farm field. It was impossible. For this reason, when the apparatus reaches an inclined ground during the work, it is not easy to continue the harvesting work by scratching the foliage corresponding to the inclination direction, and the black film laid on the field during the harvesting work is used as the radish. There was a problem of scratching together.

  In addition, a conventionally known pulling / conveying mechanism has a free end at the top that can be rotated in the vertical direction. However, a foliage cutting mechanism is provided in the vicinity of the base end of the pulling / conveying mechanism. The extracted radish is sandwiched between transport belts provided in the pulling and transporting mechanism, and the foliage portion is cut while being transported, and is delivered to a collecting conveyor provided immediately below the pulling and transporting mechanism. In the prior art, the pulling / conveying mechanism is rotatable about the fulcrum shaft, so when the work position of the pulling / conveying mechanism is adjusted in the vertical direction, the end position of the pulling / conveying mechanism and the height of the collection conveyor change. In some cases, the radish could not be delivered to the center of the collection conveyor. The radish dropped from the collection conveyor may be damaged and lose its commercial value.

  In the conventionally known radish harvesting work machine, since the pulling and conveying mechanism is rotatably attached to the base end by the fulcrum shaft, the height of the radish cut from the foliage is transferred to the collection conveyor is the pulling and conveying mechanism. Therefore, there was a problem that the radish could not be delivered to the center of the collection conveyor.
