Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a seeding machine for sowing seeds on a plant cultivation block.

[Prior Art] This will be explained with reference to FIGS. 3 and 4. Seeds A are dropped from the downward seed drop tube 1 of the seeding machine into the center of a cross-shaped cut 3a formed vertically in a plant cultivation block 3 made of a rectangular urethane block placed in a seedling box that moves together with the conveyor. When sowing seeds, a funnel-shaped seed receiver 4 having a lower insertion tube with a small diameter to allow the seeds to pass through is used.
It is conceivable to insert this into the center of the cut 3a. In this case, it is easier to insert the seed receiver 4 into the center of the cut 3a by making the diameter of the lower tube for insertion as small as possible.

[Problems to be Solved by the Invention] Since the seed receiver 4 is inserted into the cut 3a of the moving block 3, the block 3 may be damaged, or the seeds may not be inserted into the crack and may be damaged due to the elasticity of the urethane. It has the disadvantage that it returns to the surface and remains on the surface.

The present invention has been made to solve these problems, and an object of the present invention is to provide a seeding machine that can hold seeds inside the urethane without damaging the blocks.

[Means for solving the problems] As shown in FIGS. 1 to 3, the present invention has the following features:
Plant cultivation blocks 3 arranged in multiple places in the seedling box
Seeds A are placed in the center of the radial vertical cut 3a formed in the downward seed dispensing tube 1 provided at the bottom of the sowing machine.
In a seeding machine that drops seeds, a seed droplet is provided below the downward seed dropping tube 1, which has a considerably larger diameter than the diameter of the downward seed dropping tube, and which has a diameter around the center of the cut 3a on the upper surface of the block 3 when dropping seeds. The expanding cylindrical body 2, which is pressed to expand the center of the cut 3a, is arranged to be movable up and down.

[Function] The center of the cut 3a of the block 3 is expanded by the cylindrical body 2.
Since it can be expanded by pressing the block 3, the sowing of the seeds A is performed reliably, and since the expanding cylindrical body 2 only presses the top surface of the block 3, even if the block 3 is displaced, the seed A can be sown without fail. The cylindrical body 2 does not slide on the upper surface of the block 3 and damage it.

[Embodiment] An embodiment of the present invention will be described based on FIGS. 1 to 3.

Reference numeral 1 denotes a downward seed dispensing tube of the sowing machine, and 2 denotes an expanding cylindrical body, which has a considerably larger diameter than the diameter of the downward seed discharging tube, and is disposed below the downward seed discharging tube 1 of the sowing machine. It is arranged so that it can move up and down.

A rectangular parallelepiped plant cultivation block 3 made of urethane foam, which is arranged adjacent to each other in a seedling box moved by a conveyor, has cross-shaped cuts 3a at the top and bottom.
is formed.

When the block 3 is moved below the downward seed dropping tube 1 as shown in FIG. 1, the expanding cylindrical body 2 is lowered as shown in FIG. 2 and presses around the center of the cut 3a. The center of the cut 3a is widened to form a recess H. At the same time, seeds A are thrown into the recess H from the downward seed dropping cylinder 1. When this seeding is finished, the expanding cylindrical body 2 is raised and the recess formed in the block 3 disappears due to the restorability of the block 3.

[Effects of the Invention] This invention provides radial cuts 3 below the downward seed dropping tube 1 of a seeding machine that sows seeds into a plant cultivation block 3 by pressing the top surface of the block 3 when dropping seeds.
Since the expanding cylindrical body 2 that expands the center of the block 3 is movable up and down, seeds can be reliably sown in the center of the cut 3a of the block 3, and the funnel-shaped seed receiver can be Unlike the case where the block 3 is inserted into the center of the cut 3a, the block 3 is not damaged.
