Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a seeding machine for sowing a plant cultivation block.

[Prior Art] As shown in FIG. 3 and FIG. 5, a cross shape vertically formed on a plant cultivation block 4 made of a rectangular urethane block arranged in a nursery box moved by a conveyor.
... That is, four radials ... When seed A is dropped from the seed dropping port 1 of the seeding machine to the center of the cut 4a and seeded, it is conceivable to insert a funnel-shaped seed receiver 9 into the center of the cut 4a.

[Problems to be Solved by the Invention] The seed receiver 9 moves, and the cut 4a of the block 4 moves.
However, there is a drawback that the block 4 is damaged or the seed A is not inserted into the cut 4a and returns to its original state due to the elasticity of urethane and remains on the surface.

The present invention was made in order to solve such a problem, and a seeding machine in which the seeds A are sandwiched inside urethane by allowing the radial cuts 4a to reach a large desired depth without damaging the block. It is intended to provide.

[Means for Solving the Problems] The present invention, as shown in FIGS. 1 to 4, includes at least three radial cuts in the vertical direction formed in a plurality of plant cultivation blocks 4 arranged in a nursery box. 4a is a seeder that drops seeds A from the seed drop opening 1 in the center, and below the seed drop opening 1, the cylindrical bodies 2 and 5 having at least three cuts 3 and 6 formed at the lower end are moved up and down. Arranged as possible,
The projections 2a, 5a at the lower ends of the cylindrical bodies 2, 5 enable the virtual planetary point B between the adjacent cuts 4a, 4a on the upper surface of the block 4 to be pressed and spread when the seed is dropped. It is configured in.

[Operation] When the virtual planetary points B, ..., B between the adjacent cuts of the radial cuts 4a of the block 4 are pressed by the protrusions 2a at the lower end portion in which the plurality of cuts 3 and 6 of the tubular bodies 2 and 5 are formed. Since the virtual planetary point B on the upper surface of the block 4 is pressed by the plurality of projections 2a at the lower end portion, the center of the cut 4a is widened further. Therefore, the seed A is surely sown in the center of the cut 4a.

[Embodiment] A first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

1 is a seed dropping port of a sowing machine, 2 is a tubular body, and at least 3 ... for example 4 notches 3 are formed in the lower end portion,
It is arranged in the seeder below the seed drop port 1 so as to be vertically movable.

A rectangular parallelepiped plant-cultivating block 4 made of foamed urethane, which is arranged adjacent to each other through a pot 4b in a nursery box moving on a conveyor, has at least three radial ..... 4a is formed.

Then, as shown in FIG. 1, the block 4 is the seed drop port 1
The cylindrical body 2 is pushed down as shown in FIG.
The virtual planetary point B between the adjacent cuts 4a of 4b is pressed to widen the center of the cut 4a to form a recess H.
The recess H is effectively expanded by the protrusion 2a and the notch 3. At the same time, the seed A is dropped into the recess H from the seed dropping port 1. After this sowing, the tubular body 2 is lifted,
The recess H formed in the block 4 disappears due to the restoring property of the block 4.

FIG. 4 shows a second embodiment of the present invention, in which at least three, eg, four, notches 6 are formed in the lower end of the tubular body 5, and slits 7 and through holes are formed in the valleys thereof. 8 are provided. The action of the tubular body 5 is substantially the same as that of the tubular body 2 of the first embodiment, but if a soft or elastic material is used as the material, the slit 7 and the through hole 8 make the projection 5a at the lower end portion more elastic. Since it has, the expansion effect can be obtained by pressing the block 4.

[Effects of the Invention] This invention is a lower end that spreads the center of the radial cut 4a by pressing the upper surface of the seed block 4 below the seed drop opening 1 of the seeding machine that seeds the block 4 for plant cultivation. Since the tubular bodies 2 and 5 having the plurality of notches 3 and 6 formed therein are arranged so as to be vertically movable, the notches 3 and 6 of the tubular bodies 2 and 5 and the projections 2a and 5a form the block 4 Effectively expanding the center of the notch 4a to cut the seed A into the notch 4a
The seeds can be surely sown in the center of the block, and the block 4 is not damaged as in the case of inserting a funnel-shaped seed receiver in the center of the cut.
