The spiral roll 16 has a starting end 21 with a low H shape and a terminal end 22 with a high H shape, and when viewed from the side, the axial direction is set so that both ends are higher, and the lower starting end 21 side is the seed supply side. As a result, each drop port 40 of the seed rice supply hopper 14 is opened above the starting end portion 21 of the roll groups A and H.

The suction device 25 provided below each spiral roll 16,
A suction port 42 is opened in either the left or right side plate 41 of the suction case 26. A hose of a suction machine (not shown) is connected to the outside of the suction port 42. The suction device 25 allows suction air to blow through the seed moving groove 20 from top to bottom, and sucks the seeds moving in the seed moving groove 20 downward, so that the seeds stand upright and fit into the seed moving groove 20. Between the starting end 21 and the terminal end 22 of the spiral rolls 16 arranged in parallel to allow the seeds to be sucked into the groove, there is a layer between the starting end 21 and the terminal end 22 at the upper position of the seed transfer groove 20. The 0-rotation brush 43 is provided with a rotating brush 43 that smooths out the seeds moving in the seed moving groove 20 toward the seed moving groove 20. The zero-rotation brush 43 is rotated by a motor so as to sweep the seeds back toward the starting end 21.

A guide 4 is provided on the upper surface of the spiral roll 16 on the starting end 21 side.
5 will be provided. The guide 45 is for preventing the seeds from moving from the seed moving groove 20 to the adjacent seed moving groove 20 due to the rotation of the spiral roll 16. Form to cover. The lower surface of the guide 45 is connected to the spiral roll 16
The spiral roll 16 is formed into a semicircular arc shape to match the upper surface of the spiral roll 16
A large number of them are arranged in parallel with a slight gap near the upper surface, and their bases are fixed to the horizontal rod 46 and formed integrally.
6 is attached to the suction case 26.

A motor 47 is provided in front of the seeding device in the transport direction, and a bed soil supply device 48 is provided in front of the motor 47. The bed soil supply device 48 includes a hoe 2 par 49 and a feeding belt 5.
0, the soil supply amount adjusting device 51, etc.

A plurality of guide rolls 52 for moving the storage case 2 are provided on the horizontal transfer table l. The guide roll 52 is connected to the motor 47 by a chain 753. Note that the guide roll 52
It may also be used as a guide belt instead.

Next, we will discuss the effect.

When the storage case 2 fitted with the paperbot seedling box 4 is placed on the supply side 6 of the horizontal transfer table l, it is transferred by the guide roll 52, and below the soil covering supply device 7, the pot 5 of the paperbot seedling box 4 is covered with soil. IO is supplied and further advances,
It reaches below the seeding device 12.

The IJ @ spiral grooves 17 and peaks 18 of each spiral roll 16 of the seeding device 412 rotate in a state in which the right and left sides coincide with each other, and the upper surface between each spiral roll 16.16 has a Y
A mold-shaped seed moving groove 20 is formed, and a fitting groove in which the left and right spiral grooves 17 are combined is formed at the bottom of the seed moving groove 20.

When the sprocket 38 attached to the shaft 24' of the spiral roll 16 is rotated by the checker 739, each spiral roll 16 rotates to the left (or right) at the same time, so that the fitting groove of the seed transfer groove 20 is Proceed in the direction of arrow A in a matched state. Therefore, the storage case 2 is the sowing device 1.
2, the front seeding device 14 first spreads the pots 5 at odd-numbered places on the left and right sides of the paperbot seedling box 4.
When the storage case 2 moves below the seeding device 15, the seeds 20 are fed into the pots 5 at even-numbered locations.

A suction device 25 is provided below the spiral roll 16, and when air is sucked from the suction port 42 of the device 25, suction air blows from top to bottom through the fitting groove of the seed transfer groove 20. Since the seeds 19 moving in the seed moving groove 20 are sucked downward, the seeds 20 fit into the fitting groove in an upright state, and move in the seed moving groove 20 in the A direction without coming off while being fitted.

The seeds that have moved to the terminal end 22 of the seed transfer groove 20 fall one by one from the seed drop port 36, move within the drop chute 30 below the seed drop 1'' 36, and then move to the drop chute 3.
0 is formed directly above the pot 5 of the paper pot seedling box 4 from the lower end 54 of the paper pot seedling box 4, so that - grains fall one by one to the center of the pot 5 of the paper pot seedling box 4 passing just below by the guide roll 52. .

When seeds are supplied to the seed transfer groove 20 from the hoist, the rotation of the spiral roll 16 causes the seeds to move to the adjacent seed transfer groove 20. Since the guide 45 is formed and serves as a wall, seeds do not move to adjacent seed moving grooves 20, and seeds are evenly supplied to each seed moving groove 20.

Since the rotating brush 43 rotates so as to sweep out excess seeds (seeds not fitted into the fitting groove 19) toward the starting end 21, the rotation of the rotating brush 43 sweeps them back toward the starting end 21.

In this case, one seed 20 falls when each spiral roll 16 rotates once in a --striped spiral, two seeds fall when each spiral roll 16 rotates once in a double-striped spiral, and two seeds fall when each spiral roll 16 rotates once in a multi-striped spiral. When the roll 16 rotates once, many particles fall.

Therefore, if the rotational speed of each spiral roll 16 by the motor is adjusted to a designed speed, 1. For example, one seed can be dropped one by one into the center of the pot 5 of the paper pot seedling box 4 that is just passing below. becomes possible.

The storage case 2 is then further advanced by the guide roll 52, and the floor is fed by the floor feeding device 48, completing the seeding.

As already mentioned, the use of soil-grown seedlings for rice transplanters has progressed from the use of para-sown Jukin-nae to the use of row-sown Doki-nae. And recently, it is called paper pot seedling,
Seedlings sown one by one are appearing in paper boxes made of paper material. This soil-attached seedling has thicker and stronger stems than conventional seedlings, so it has been confirmed that it is resistant to cold damage. Therefore, although it is quite popular, there has never been a device that can reliably sow one seed at a time in small pots, making it difficult to create paper pot seedlings.

However, in the present invention, a large number of spiral rolls 16 each having a spiral groove 17 for transferring seeds 19 on the outer circumferential surface are arranged in parallel, a Y-shaped seed moving groove 20 is formed between the spiral rolls 16, and a Y-shaped seed moving groove 20 is formed between the spiral rolls 16. One is formed as a starting end 21 and the other is formed as a terminal end 22,
In the device in which a suction device 25 is provided below the spiral roll 16, a seeding device is provided with a dropping chute 30 for the seeds 19 at the terminal end 22 of the moving groove 20, and a suction case 25 is provided below the spiral roll 16. and suction case 26
The seeding device has a side wall made of a synthetic resin wall 31, and a falling chute 30 for the seeds 19 is provided on the synthetic resin wall 31, and the falling chute 30 forms a ]-shaped groove on the surface of the synthetic resin wall 31. Metal frame 3 provided outside the resin wall 31
Since the seeding device is formed into a mouth-shaped shape by surrounding the mouth-shaped groove as shown in FIG. 7, the seeds are reliably dropped one by one into the small pot.

Since the drop chute 30 is provided below the seed drop port 36, the seeds 19 can be guided accurately.C.A suction case 26 is provided below the spiral roll 16, and the side wall of the suction case 26 is made of a synthetic resin wall 31. , seeds 1 are placed on the synthetic resin wall 31.
Since the falling chute 30 of 9 is provided, the falling chute 30
But it's easy to do.

This effect is achieved.
