JPS599Y2 - Bulbous crop planting device - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a planting mechanism of a bulbous crop planting device.

In conventional bulbous crop planting devices, the planting mechanism is of the perforated roll or bucket roll rotating type, and the planting accuracy is not stable, many plants are missing, and the planting interval is also irregular.

The present invention has been devised in view of the above points, and its purpose is to provide a bulbous crop planting device that reliably plants bulbs one by one at regular intervals.

In order to achieve the above object, the present invention forms a V-shaped groove by arranging two conical bodies with their tops inside and facing each other at appropriate intervals on the same axis, and forming a V-shaped groove on the facing tapered surfaces of the V-shaped groove. A drum having protrusions arranged symmetrically and at regular intervals; a drum shaft having an appropriate number of drums fixed thereon and rotatably disposed at the tip of the supply plate with a predetermined gap; and the supply plate. and a V-shaped guide plate that is disposed between the drum shaft and the drum shaft and swings up and down within the square groove of the drum.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
As shown in FIGS. 1 and 2, the rotation of the axle 2 of the implanter 1 is transmitted to the intermediate shaft 4 by the belt 3, and then from the belt 5 to the gear 6.7, the rotation is transmitted to the axle 2 at the rear of the machine. The signal is transmitted to the drum shaft 8, which is rotatably arranged parallel to the drum shaft 8.

A suitable number of drums 9 for implantation are fixed to this drum shaft 8, and rotate in a direction opposite to the rotational direction of the wheels 2'.

As shown in FIGS. 3 and 4, this drum 9 is made of iron plate cones 9 a and 9 b with their tops facing inwards and facing each other coaxially at appropriate intervals to form ■-shaped grooves. On the opposite tapered surfaces of this ■-shaped groove, there are cones 9a, 9.
A number of protrusions 10 having a triangular cross section are provided symmetrically and at regular intervals from the top of b toward the edge.

One axial force of the PTO shaft of the implanter 1 One rotation As shown in FIG. The back and forth movement of the attached ball joint (of the crank mechanism) 15 is converted into left and right movement by the link mechanism 16.

As shown in FIG. 7 in detail, this motion is transmitted to the crank arm 18 of the transmission shaft 17, and the transmission shaft 17 moves in an arc.

This arcuate motion causes the swing plate 20 to swing up and down by a swing crank 19 attached to the tip of the transmission shaft 17, as shown in FIG. 8 in detail.

This swing plate 20 has a support rod 2 fixedly attached to the swing plate 20.
1 is rotatably provided on the drum shaft 8, and the drum 9
It is arranged at the lower end of the supply plate 22, which is inclined so that the front side of the implanter 1, that is, the side of the drum shaft 7 is lower. This receives the bulbs that have moved on the supply plate 22 from the hopper 23 and moves them to the center of the drum 9.

As shown in FIG.
) in the mill direction, tilt the drum shaft 8 slightly downward to make it easier, and move the drum 9
The V-shaped guide plate 25 is slightly separated from the protrusion 10 of the groove-shaped slope.
is fixed, and moves up and down in the V-shaped groove of the drum 9 by the up and down movement of the swing plate 20.

Even when this V-shaped guide plate 25 is moved down the most with the drum shaft 8 as its virtual axis, the bulbs 24 touch the outer edge of the V-shaped guide plate 25 and the drum shaft 8. The size and positional relationship are such that there is a gap between the V-shaped groove slope of the drum 9 and the tip of the supply plate 22 to prevent the supply plate from falling.

The bulbs 24 are either sent from the hopper 23 through the supply plate 22 to the planting drum 9 as shown in FIGS. 1 and 3, or sent to the planting drum 9 as shown in FIGS. 2 and 10. 22
It is brought to the front of the drum 9 by the upper separation protrusion 26.

7. Then, the bulbs 24 are inserted into the separation protrusion 26 of the supply plate 22. Due to the tip of the drum 9 and the V-shaped guide plate 25, it moves from the gap onto the V-shaped guide plate 25 without falling out of the machine.

Since the ■-shaped guide plate 25 is slightly inclined and oscillates downward from the drum axis of the drum 9, the bulbs 24 move toward the center of the drum 9 on the V-shaped guide plate 25. It is held in contact with the slope inside the ■-shaped groove of the drum 8.

Next, the bulbs 24 are attached to the protrusions 10 of the rotating drum 9.
The field is hooked onto the ground, lifted away from the V-shaped guide plate 25, rotated together with the drum 9, carried down to the bottom, and cut into a field that has been cleared and leveled in advance by the groove-cutting reroller 27, which rotates with ground pressure. It falls under its own weight into the planted groove (the planting interval can be changed as appropriate by replacing the gears 6 and 7).

According to the present invention, as shown in FIG. 9, only one bulb 24 is always caught on the protrusion 10 on the slope of the ■-shaped groove of the planting drum 9, regardless of the size of the bulb 24. .

If the bulbs 24 are small, only the one that has advanced closest to the center of the drum 9 will be caught by the protrusion 10, as shown in FIG. 9a, and if the bulbs are large, as shown in FIG. In the case of small bulbs, they do not progress in any direction towards the center of the drum 9, but only the one that has advanced the most will reach the protrusion 1.
It gets stuck at 0.

Regardless of the size of the bulbs, if one bulb is caught, the next one will not be caught at the same time.

Therefore, both large bulbs and small bulbs can be planted one by one at regular intervals, and there is no need to replace the planting drum depending on the size of the bulbs.
