Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seeding device for a bulb seed or the like having a projection, and more specifically, it is a plant for continuously planting bulbs while aligning them in the vertical direction.

[0002]

2. Description of the Related Art Up to now, many devices for planting bulb seeds have been proposed. For example, Japanese Examined Patent Publication 5-28564
The ones described in the issue are known. The technology disclosed in this publication can reliably adjust the planting interval regardless of large and small bulbs, and can surely dispense a large amount of bulbs into the hopper in order to increase the planting efficiency. It is related to.

[0003]

By the way, when seeds having a germination projection on the top of garlic or the like are aligned vertically and planted with the roots facing downward, stable and uniform growth of the rhizomes of the rhizomes is achieved. It is known to obtain a high quality harvest. Also in the garlic cultivation test, it was confirmed that the more vertical the vertical inclination is, the more stable and uniform growth was obtained, and the result was favorable. However, in the above-mentioned known planting device, control and adjustment in the vertical direction of seeds are not taken into consideration at all, and bulbs or the like are laterally oriented, non-paged (2) regular planting such as upside down, and garlic and the like as they are. When used for sowing, there is a risk that growth may be suppressed or yield may be reduced.

[0004]

In view of the above problems, the present invention is a seeding device having the following features. That is, it is an apparatus for sowing bulb seeds or the like, which comprises a supply hopper and a rotating cylindrical cylinder having a hole through which the projection of the seed is caught when the seed having the projection passes through the inside, or a rotating cylinder. Further, the seeding device has a structure in which a coil-shaped elastic body having a diameter substantially equal to the cylinder diameter is provided in the joint portion of the rotating cylindrical cylinder.

[0005]

When the bulb seeds are moved from the feed hopper into the appropriately tilted rotating cylindrical cylinder of the present invention, the bulb drops while contacting the inner wall of the cylindrical cylinder. When the projecting portion is in the downward state, the dropped seeds are caught by the hole in the inner wall of the cylindrical cylinder or the projecting portion and are inverted, and the seeds are discharged while being aligned in the vertical direction and sown.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing the embodiment of the present invention, and FIG. 2 is a sectional view of a rotating cylindrical cylinder portion which is a main portion.

Reference numeral 1 is an engine, which is transmitted to the drive wheels 31 and the seeding device side via the main transmission 2 of the engine. Reference numeral 18 is a traveling clutch. A transmission 3 receives the power from the main transmission 2 and transmits the rotational force to the transmission vehicle A and the transmission vehicle B.

Reference numeral 20 designates a frame, on which the above-mentioned submission 3 is placed, and on the rear upper part is arranged a hopper 11 for introducing bulb seeds. A vibrating hopper 12 is arranged below the hopper 11. Page (3)

Reference numerals 21 and 22 denote joint frames, and the support shaft C
The cylindrical cylinder 15 is swung with the support shaft B24 as a swinging reference point. The perforator 10 is attached to the lower end of the cylindrical cylinder 15. The cylindrical cylinder 15 is formed with a hole or a protrusion where the seed protrusion is hooked and engaged.

A crank 9 transmits the rotational force of the transmission wheel B5 to swing the swing arm 8. The rear end of the swing arm 8 is fixed to the upper end of the above-described hole puncher 10 by a support shaft D so as to be swingable.

Reference numeral 27 is a rod for opening the perforator 10 left and right in the traveling direction at a set timing by rotating the pressing piece 28 utilizing the action of the swing arm 8. Reference numeral 16 is a grounding wheel whose height can be adjusted to adjust the implantation depth of the opener 10. Reference numeral 14 denotes a cam bar, which changes the swinging of the joint frame 21 into a horizontal action, and the plate 1
Rotate 3.

Next, the supporting structure and the like of the rotating cylindrical cylinder 15 will be described with reference to FIG. A bearing 29 is supported by the frame 20 and the joint frames 21 and 22 described above, and the cylindrical cylinder 2 is mounted in the bearing 29. The transmission wheel 7 is provided above the bearing 29, and receives the rotational force from the transmission wheel C to rotate the upper and lower cylindrical cylinders 15. The boss portion of the transmission wheel 7 serves as a passage guide for the bulb seeds sent from the eye plate 13.

The boss portion of the transmission wheel 7 and the cylindrical cylinder 15
Upper part of joint and upper joint frame 21 and lower joint frame 22
And the coil-shaped elastic bodies 32 are connected between them. Therefore, when the transmission wheel B5 rotates and the perforator 10 moves F through the swing arm 8, the respective joint movements are absorbed by the coiled elastic body 32 while the bulb smoothly rotates inside. While falling. Page (4)

A spindle 30 rotatably supports the plate 13 and is pivotally attached to a vibrating hopper, and a roller is provided at the lower end of the spindle 30. A convex portion that matches the position of the roller is provided on the upper surface of the transmission wheel 7 to vertically vibrate the vibration hopper 12 simultaneously with the rotation.

In the present embodiment, the number is set to 1 in the drawing, but in the case of garlic bulb sowing, the number is set to 4 and the operator runs the ridge groove by the offset handle 17.

[0016]

[Effect] With the above-described structure, in sowing work of a bulb having a projection, the projection of germination can be surely aligned with the projection upward so that efficient seeding is possible.
