Abstract

PURPOSE:To obtain the title device automatically carrying out dividing operation without damaging buds by inserting a separating pawl into a storage part of rush seedling from the root side in the direction of culm of stored rush mother stock to the side of stem tip, circulating and driving the pawl in the locus separating from the direction to cross the culm of rush. CONSTITUTION:In a dividing device wherein a pawl device 2 and a storage part 3 of rush mother stock A are arranged on a side wall face 1a of a case main body 1 having a built-in driving gear, the pawl device 2 has a chopstick- like separating pawl 2a, the separating pawl is detachably fixed to a separating arm 2b; the separating arm 2b is supported by a rocking arm 2d rotatably attached to the side wall surface 1a, the separating pawl 2a is inserted into the storage part 3 with laying the root part toward the side of the pawl device 2 from the root side in the direction of culm of the rush mother stock A fed in the horizontal attitude to the side of stem tip. The separating pawl is driven and circulated in the locus downward departing from the direction to cross the rush culm to divide the large mother stock A into small rush seedlings (a) and a transfer stopping pawl 6 for preventing movement of the mother stock A is equipped.

Description

[Detailed description of the invention] [Industrial application field] When planting strawberry seedlings in paddy fields, after washing off the mud adhering to the roots of the seedlings dug out from the nursery bed, the large parent plants are transformed into small plants suitable for planting. It is necessary to separate. The present invention relates to a device for dividing rice seedlings for automatically carrying out this dividing operation.

[Conventional technology]

The conventional plant separation device was configured to strip the parent plant into strips using a separation tool from the direction intersecting the rush culm, and then cut the strip-shaped seedlings into appropriate numbers of plants using a cutter (for example, using a special method). (Refer to Japanese Patent Publication No. 1985-85304).

[Problem to be solved by the invention]

Rush seedlings reproduce by growing new shoots at the base of the parent plant. In the conventional technology, the plant was divided using a separating tool that penetrates from the direction that intersects with the strawberry culm, but the separating tool that separates the entangled roots acts directly on the new shoots, piercing or chipping them. There was a risk.

The present invention solves the above-mentioned problems of the prior art, and aims to provide a device for dividing strawberry seedlings without damaging the new shoots.

[Means to solve the problem]

In order to achieve the above-mentioned object distantly, the present invention provides a method for inserting a separating claw of a strawberry seedling into a strawberry seedling accommodating part from the root side of the culm of the accommodated strawberry parent plant to the stem end side, It is driven in a circular manner with trajectories spaced apart in intersecting directions.

Further, the strawberry seedling storage section is provided with a movement preventing claw that penetrates into the roots of the accommodated strawberry parent plant in conjunction with the insertion of the separating claw into the strawberry seedling storage section and prevents the parent plant from moving in the direction of separation. You can also do it.

[Effect]

The apparatus for producing rice seedlings of the present invention configured as described above is as follows:
The separating claw is inserted from the root side to the stem tip side along the culm direction so as not to intersect with the rice seedling, and after entering the plant from the root side, it is separated in the direction crossing the rice culm direction. It works like dividing stocks. In addition, the strawberry seedling storage section works to hold the parent plant against force.

When a movement-preventing claw is provided that penetrates into the roots of the accommodated strawberry parent plant, the blocking claw works to hold the rush seedlings on the upper side of the plant.

〔Effect of the invention〕

Therefore, the following effects can be expected from the apparatus of the present invention.

B. Since there is no crossing between the strawberry seedlings and the separating claws when inserting them into the housed strawberry parent plant, there is less crossing between the separating claws and the new shoots, making it easy to divide the plants without damaging the important new shoots.

The opening and separating claws enter the plant from the root side along the culm direction of the parent plant, making it easy to insert deeply without much resistance, compared to the configuration of conventional technology in which the plant is stripped from the side of the parent plant. This makes it easy to divide tightly tangled strawberry seedlings without damaging the new shoots.

C. If a movement-preventing claw that penetrates into the root of the parent plant is provided, it will directly support the parent plant, so compared to a structure that prevents the movement of the parent plant by, for example, holding the stem of a rush seedling, it will prevent the parent plant from moving in the direction of separation. It is easier to divide the stock by reliably preventing movement.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show an apparatus for growing strawberry seedlings according to a first embodiment of the present invention. In Fig. 2, a claw device (2) and a accommodating part (3) for the parent plant (A) are arranged on the side wall surface (1a) of the case body (1) in which the drive device is installed. It makes up the whole. The code (4) in the figure is

In FIG. 1, the accommodation section (3) for the parent rice plant (A) is constituted by a container whose left side and top surface are open on the paper. The bottom of the storage section (3) has a concave shape that guides the parent plant (A) placed in a horizontal position toward the seedling outlet (3a). A release guide (9) for seedlings (a) is provided in series. In order to actively press the parent plant (A) toward the seedling outlet (3a), a crank-shaped stock holding rod (5) is swingably installed between the side walls of the storage section (3). A biasing spring (5b) is stretched between the operating arm (5a) fixed to the end of the housing (5) and the accommodating portion (3). Storage part (3
) In order to prevent the parent plant (A) introduced into the chamber from moving in the separation direction, a movement preventing claw (6
) has been established. This movement preventing claw (6) is connected to the housing portion (3).
) moves in and out guided by the slide tube (6a) fixed to the front wall of the nail shaft, and by the force of the spring (7) fitted onto the claw shaft, it retreats from the accommodation portion (3) and enters the regulating device (8). It is biased to return to the abutting position. Said separating arm (
