  However, in the case where trouble such as clogging occurs in one of the left and right two rows of the alignment transfer unit, the alignment supply device stops the entire apparatus in order to operate on one side after removing the troubled transfer material. In addition, there is a problem in that the alignment transfer capability is halved by one-side operation, resulting in a great confusion.

  The problem to be solved is that in the root crop crop aligning and feeding apparatus composed of the slanting transport section, the sorting section, the left and right aligning transport section, etc., even if trouble occurs on one side, the transported material does not stay. Another object of the present invention is to provide an aligning and supplying apparatus capable of continuing the aligning and supplying by a simple operation without degrading the processing capability.

  The invention according to claim 1 includes a slanting transfer part (3) for pulling up the root crops introduced into the storage part (2), a distribution part (4) for distributing left and right from the center of the entire transfer width, In the root crop crop aligning and feeding apparatus comprising left and right aligning and transferring units (5j, 5k) that receive and transfer in two rows respectively, the sorting unit (4) is configured to move the entire width by sliding operation in the left and right width directions. And a slide support means (4s) for directing to one side, and the alignment transfer unit (5j, 5k) drives the side directed by the sliding operation of the distribution unit (4) to increase speed and A control unit that stops driving is provided.

  When the above-structured uplift transport unit pulls up the root vegetable crop from the storage unit, the distribution unit provided in the center of the entire transfer width distributes the root vegetable crop left and right, and the left and right rows of aligned transport units receive the root vegetable crop. By aligning and transferring each, the root crops can be individually supplied to the measuring unit or the like one by one. At this time, if the distribution unit is slid to the left or right side, the alignment transfer unit on the left and right sides of the machine body is stopped, and the one side operation of the alignment transfer unit on the other side of the machine body is switched. The conveying speed of the aligning / transferring unit is increased, and the aligning operation can be performed with substantially the same efficiency as the both-side operation.

According to a second aspect of the present invention, in the configuration of the first aspect, the left and right aligned transfer parts (5j, 5k) are transferred in two rows from one end to one side by a common drive (11a, 11b). These two rows of horizontal transfer sections (11a, 11b) are characterized in that transfer sections by a plurality of partitions (11c) are formed in a staggered arrangement.
The two rows of horizontal transfer sections configured as described above separate and supply root crops at high speed, and the horizontal transfer section has a staggered transfer section to suppress movement between adjacent areas, and the common drive simplifies the configuration. The

  According to the configuration of the first aspect, when the distributing unit is slid to one side, the operation on one side is stopped, the operation is switched to the one-side operation by the alignment transfer unit on the other side, and the conveyance speed on the other side is increased. Therefore, the alignment supply device is efficiently aligned and supplied by the alignment transfer unit without interrupting the operation by a simple slide operation of the distribution unit, and the work efficiency is ensured by the acceleration of the alignment transfer unit. The

  In the aligned supply device according to claim 2, since the two horizontal transfer units can be supplied in parallel from the side of the single line, the root vegetable crop can be reliably separated and supplied at a high speed. Movement between adjacent rows is suppressed by the staggered transfer section of the transfer unit. In addition, since the configuration is simplified by the common drive, the maintainability can be improved.

Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
FIG. 1 and FIG. 2 are a side view and a plan view, respectively, of a root vegetable crop aligning and feeding apparatus according to the present invention.
The root crop crop aligning and feeding apparatus 1 includes a hopper 2 that temporarily stores an object such as a washed root vegetable crop to be aligned and supplied from the cleaning section C, and a conveyor that lifts the stored target. Left and right by a part 3 and a sorting part 4 by a roof-type member of both flows for distributing the object received for the entire width of the transfer to the left and right, and a conveyor (alignment transfer means) arranged in parallel on both sides of each part And the left and right shooters 6 and 6 for returning to the hopper 2 from the outer positions of the respective ends. Two rows of weighing and sorting lines M and M are arranged corresponding to the end portions of the left and right alignment transfer units 5j and 5k, and the mass of the harvested root vegetable crops is measured via the weighing and sorting lines M and M.
