Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a so-called rush plant sorting method for mechanically dividing a parent plant of rush into small planting plants, and a novel plant sorting machine used for the method. Things.

<Prior Art> Many attempts have been made to use a machine in order to eliminate the laborious work of dividing a parent plant of rush into small plants for planting. A typical example of such a structure will be introduced. For example, after inserting a plurality of splitting nails into a parent plant of rush, some of the splitting nails are rotated to split the split into small plants for planting (Japanese Patent Application Laid-Open (JP-A) no. No. 48-75323, No. 55-166414,
Japanese Utility Model Publication No. 56-35209), a method in which a parent strain is cut with a disk cutter so as to be easily separated, or a small strain is removed from the parent strain by using a chain structure in which a large number of stocking claws are provided at predetermined intervals. No. 71405) has been proposed.

<Problems to be Solved by the Invention> In the above example, the sizes of the small strains torn from the parent strain are not uniform, and there is a problem that the root buds are damaged. In the example,
Since the plants were cut, the seedlings became waste, and the roots were poor and growth was delayed. Further, in the case of the chain system, the size of the divided stock is too small, and it is necessary to close the stock later.

For this reason, without damaging the roots and buds,
The challenge was to develop an excellent method and device that could continuously divide the parent strain into small ones of a certain size.

<Means for Solving the Problems> Therefore, as a result of various studies, a stock splitting claw is inserted into the root stock of the grass to be held by the seedling feeding mechanism in the longitudinal direction of the grass above the root surface, and then the stock splitting claw is rotated. We have developed a method for classifying rush plants, characterized in that the roots are separated by moving the stock splitting claw laterally.

The structure of the plant splitting machine capable of carrying out the method of the present invention developed at the same time includes a seedling feeding mechanism (1) for holding a rush seedling and feeding a predetermined amount, and a stocking claw (2) comprising a plurality of needles.
A claw moving mechanism (5) for moving the turf in the direction of the root stock and in a direction away from the root stock; and a turning mechanism (6) for the stock splitting claw (2). In this structure, the seedling feed mechanism (1) comprises a seedling feed wheel (10) and a pair of upper and lower feed wheels (3) and (4) rotating in opposite directions, and the claw moving mechanism (5) comprises a stock splitting claw (5). The slot holder (8) attached to the holding shaft (7) of (2) is linked to a rotating disk (9) driven by a motor, and the turning mechanism (6) of the stock splitting claw (2) is provided with the holding mechanism. Cam groove (20) provided on shaft (7)
And a guide (21) for sweeping the inside of the cam groove (20).

<Effect> In the method for separating rush plants according to the present invention, the stake is inserted into the root plant of rush in the longitudinal direction of the rush from the root surface, and is rotated by the seedling feeding mechanism without damaging the roots and buds. A predetermined amount of a precise small plant is separated from the grass root plant that has been obtained and retained. In addition, the lateral movement of the stocking claw allows the planting plantlets to be completely separated from the root stock by tearing rather than cutting.

In the rush plant sorter of the present invention, the seedling feeding mechanism (1)
When the root stock of rush is supplied, the stock splitting claw (2) composed of a plurality of needles is inserted into the root by the claw moving mechanism (5). Insertion of the stock splitting claw (2) by the claw moving mechanism (5) is performed by a rotating disk (9) linked with a slot holder (8) mounted on a holding shaft (7) of the stock splitting claw (2).
Is made while rotating approximately 180 ° by the motor drive. Then, the stock splitting claw (2) inserted into the root stock is rotated by the guide (21) sweeping the cam groove (20) provided on the holding shaft (7) as the holding shaft advances, and the root stock is rotated. Is divided into a predetermined amount of small strains.

The separation of small strains by the lateral movement of the stock splitting claw (2) by the claw moving mechanism (5) is followed by the shaft holder (8) with a long hole as the rotating disc (9) is further rotated by 90 °. This is done by: According to the claw moving mechanism (5), the rotation of the rotary disk (9) causes the oblong shaft receiver (8) to follow, and the stock splitting claw (2) includes forward and backward movement and lateral movement. Follow the trajectory (a).
