Further, the present invention can, for example, collect vegetable seeds using a tractor.
This is a sowing device that can reliably sow a desired number of seeds automatically.

Conventionally, seedlings with soil for rice transplanters have progressed from seedlings sown in bulk to seedlings with soil sown in rows. Recently, paper pot seedlings have appeared. 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.

The present invention can be easily and easily applied to paper pots.
It is capable of seed spot sowing, and allows single seed seeding of vegetable seeds to be easily and easily done in the field.A large number of horizontal or inclined spiral rolls with spiral grooves formed on the outer circumferential surface are arranged side by side. A Y-shaped seed movement groove is formed between them, one of which is a starting end and the other is a terminal end, and the seeds moving from the starting end to the terminal end are returned to the upper part of the movement groove. A seeding device is provided with a leveling rotating brush whose height can be adjusted freely, and the seeding device is provided with a rotating brush that is movable up and down and in contact with the spiral roll with its own weight, and the rotating brush. is movable up and down and is provided so that it contacts the spiral roll with its own weight, and the rotary brush support device that supports the rotary brush so that it can move up and down has a device that collects seeds carried around by the rotary brush. The gist of the invention is the configuration of a seeding device equipped with a seed receiving box.

The guide 66 is formed with two surfaces: an inclined surface 68 that covers the upward rotation side 67 of the spiral roll 16, and an inclined surface 70 that covers the downward rotation side 69. The inclined surface 68 covering the rotation rising side 67 is wide enough to cover almost the entire rotation rising side 67 and is also long in the direction of movement of the seeds, so that the seeds 20 and the rotation rising side 67 are almost completely separated from each other. Avoid contact. The inclined surface 70 covering the downward rotation side 69 is formed to cover approximately half of the downward rotation side 69, and guides the seeds 20 through the seed moving groove 214. guide 66

A sprocket 75 is attached to the front end small diameter portion 34 of the spiral roll 16 of the rear roll group B, and a chain 76 is wound around each sprocket 75.

77 is a rotating shaft, and the rotating shaft 77 is connected to the side plate 52 of the seeding device 12.
It is installed on a metal frame 31 on the side.

A sprocket 78 is fixed to the shaft end of the rotating shaft 77 on the transfer direction side of the storage case 2. A bevel gear 79 is fixed to the middle part of the rotating shaft 77, and a rotating shaft 81 that meshes with a bevel gear 80 fixed to the shaft end of the drive shaft 51 is a rotating shaft installed on the metal frame 31 on the side plate 53 side of the seeding device 12. A tin rocket 82 is fixed to the shaft end of the supply side 6, and a bevel gear 83 is fixed to the middle part of the shaft 81, and meshes with the bevel gear 84 fixed to the shaft end of the drive shaft 51. A sprocket 85 is fixed at an intermediate position between the bevel gear 83 and the sprocket 82 of the rotating shaft 81, and the chino 76 is wound around the sprocket 78 of the rotating shaft 77 and the sprocket 75, which transmits the power of the motor 57 to the sprocket 85. Then, each spiral roll 16 of the rear roll group B is rotated. The chain 74 is wound around the sprocket 82 of the rotating shaft 81, and each sprocket 73 is rotated to rotate the spiral roll 16 of the front roll group A.

The spiral roll 16 has a starting end 22 with a low H shape and a terminal end 23 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 22 side is the seed supply side. As a result, each drop port 86 of the seed rice supply hopper 14 is opened above the starting end portion 22 of the roll groups A and H.

87 is the ground.

A motor 88 is provided in front of the seeding device, and a soil supply device 89 is provided downstream of the motor 88. The floor supply device 89 is formed by a hopper 90, a feed belt 91, a bed soil supply amount adjustment device 92, and the like.

A plurality of guide rolls 93 for moving the storage case 2 are provided on the horizontal transfer table 1. The guide roll 93 is connected to the motor 88 by a chino 94 and rotated. Note that the guide roll 93 may be formed by a guide belt.

Next, we will discuss the effect.

When the storage case 2 fitted with the paper pot seedling box 4 is placed on the supply side 6 of the horizontal transfer table l, it is transferred by the guide roll 93, and the paper pot seedling box 4 is placed below the soil covering supply device 7.
The cover 10 is supplied into the pot 5 and further advances to reach the bottom of the seeding device 12.

The spiral grooves 17 and peaks 18 of the spiral rolls 16 arranged in parallel rotate in a state in which the left and right sides coincide with each other, and seed transfer grooves 2 are provided on the upper surface between the spiral rolls 16 and 16, respectively.
1 is formed, and a spiral groove 17 and a fitting groove 19 in which the two spiral grooves 17 are combined are formed at the bottom of the seed transfer groove 21.

When the sprocket 85 is rotated by the motor 57, a rotating shaft 81 to which the tin rocket 85 is fixed is rotated.
rotates to rotate the tin rocket 82 fixed to the shaft end of the rotating shaft 81, and since the sprocket 82 and the sprocket 73 are wound with a chain 74, the front end small diameter portion 34 of the front roll group A is rotated. direction.

The front end small diameter portion 34 of the spiral roll 16 of the rear roll group B is
Rotating shaft 81, bevel gear 83, bevel gear 84, drive shaft 51, bevel gear 80, bevel gear 79, rotating shaft 77, sprocket 78
, chino 76, and sprocket 75 to rotate in the same direction.

Therefore, the fitting grooves 19 of the seed transfer grooves 21 move in the direction of arrow A while being aligned.

When the storage case 2 approaches the lower part of the seeding device 12, a suction device 27 is provided below each spiral roll 16 of the seeding device 14, 15, and the suction port 45 of the device 26
When the air is sucked, the suction air blows through the fitting groove 19 from top to bottom and sucks the seeds moving in the seed moving groove 21 downward, so the seeds 20 fit into the fitting groove 19 in an upright state, and , Seed transfer groove 2 without coming off while remaining in place.
1 to the terminal end 23 in the A direction.

The seeds that have moved to the terminal end 23 of the seed transfer groove 21 are dropped through the seed drop opening 41 formed between the right and left sides 40, 40 of the engaging portion 39 of the synthetic resin wall 36 provided at the terminal end 23. fall downwards. Below the seed fall port 41,
The mouth-shaped groove 42 is surrounded by the metal frame 31, and the same number of falling chutes 35 as the seed transfer grooves 21 are formed in the shape of a substantially opening (or U-shape), and the lower ends 43 of the falling chutes 35 are formed in the shape of a substantially opening (or U-shape). Because it is located directly above pot 5 of 4,
The seeds that have fallen one by one from the seed drop opening 36 are guided by the drop chute 35 and fall one by one into the center of the pot 5 of the paper pot seedling box 4. In this sowing, the seed 20 is first supplied into the pots 5 at odd-numbered places in the horizontal direction of the paper, seedling box 4 by the spot-seeding device 14, and then the seeds 20 are supplied into the pots 5 at even-numbered places in the left-right direction by the spot-seeding device 14. 20 is not supplied. Then, the storage case 2 is connected to the dispensing device 1.
5, seeds 20 go into the pot 5 at an even number.
will be supplied.

At this time, when the seeds 20 are supplied from the hopper to the seed moving groove 21 , the seeds are moved to the adjacent seed moving groove 21 due to the rotation of the spiral roll 16 . The sloped surface 68 on the rotationally rising side 67 of the spiral roll 16 is formed wide and long, and the sloped surface 68 is moved toward the rotationally rising side 67 to form the guide 66.
Since it is a wall, the seeds 20 are moved into the adjacent seed transfer groove 2.
1, and the seeds are evenly supplied to each seed transfer groove 21.

The rotating brush 47 is configured such that the inner end of a rotating arm 49.50 is fixed to a drive shaft 51, the shaft 48 of the rotating brush 47 is fixed to the outer end of the rotating arm 49.50, and the rotating brush 47 is driven by the shaft 48. Fix pulley 54.54° and passive pulley 55.55'
The motor 57 rotates the sprocket 85 to rotate the rotating shaft 81, rotates the bevel gear 83 fixed to the rotating shaft 81, and connects the drive shaft via the bevel gear 84. 51 is rotated, each outer side of the rotating brush 47 moves up and down freely around the drive shaft 51, and comes into contact with the spiral roll 16 by its own weight. Then, it is rotated so as to sweep the seeds back toward the starting end 22 side. Therefore, the rotating brush 47
removes excess seeds (seeds that are not fitted into the fitting groove 19),
As the rotating brush 47 rotates, the seed rice with awns is swept back toward the starting end 22 side, and the awns attach to the rotating brush 47 once, rotate together, and are collected in the seed receiving box 61. Therefore, only the rice seeds without awns move into the seed transfer groove 21, which makes it easier to fit into the fitting groove 19, ensuring that each seed moves one by one. At this time, the rotating brush 47 that smoothes the seeds moving in the seed moving groove 21 needs to have its tip positioned on the upper surface of the seed moving groove 21 . The adjustment screw 63 is
The rotary arm 49.5O is supported by bringing its lower end 65 into contact with a receiving plate 64 formed by bending the upper end of the side plate 52.53 of the seeding device 12 inward. Then, when the adjusting screw 63 is rotated clockwise, the horizontal rod 59 rises, and the rotating arm 49.50 is rotated upward about the drive shaft 51.
Conversely, when the adjusting screw 63 is rotated to the left, the horizontal rod 59 is lowered and the rotating arm 49.50 is rotated downward about the drive shaft 51, so that the shaft 48 of the rotating brush 47 is aligned with the side plate 52.
．． 53 to adjust the degree of contact between the rotating brush 47 and the spiral roll 16.
7 and the seed receiving box 61.

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 each seed 20 falls in a multi-striped spiral. When the spiral roll 16 rotates once, many particles fall.

Therefore, if the rotational speed of each spiral roll 16 by the motor 57 is adjusted to a designed speed,
For example, it becomes possible to drop one seed at a time into the center of the bot 5 of the paper bot seedling box 4 that is just passing below.

The storage case 2 is then further advanced by the guide rolls 93, and the bed soil is supplied by the bed soil supplying device 89.
Sowing is complete.

As already mentioned, conventional seedlings with soil for rice transplanters have progressed from using seedlings with soil sown in bulk to seedlings with soil sown in single rows. Recently, paper pot seedlings have appeared. 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.

As already mentioned, conventional seedlings for rice transplanters have progressed from para-sown seedlings to row-sown seedlings. Recently, paper pot seedlings have appeared. 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 horizontal or inclined spiral rolls 16 each having a spiral groove 17 formed on the outer peripheral surface are arranged in parallel, a Y-shaped seed movement groove 21 is formed between the spiral rolls 16, and the movement groove 2
1 has one end as a starting end 22 and the other as a terminating end 23, and the upper part of the moving groove 21 has a terminating end 23 from the starting end 22.
A rotating brush 47 that smoothes the seeds while returning them as they move toward the
A seeding device 4 whose height is adjustable, and a seeding device in which the rotating brush 47 is movable up and down and in contact with the spiral roll 16 with its own weight; 47 is vertically movable, and is provided so as to contact the spiral roll 16 with its own weight, and a rotary brush support device that supports the rotary brush 47 so as to be able to move vertically includes a rotary brush 47 that can be held by the rotary brush 47. Since the gist of the invention is the configuration of a seeding device equipped with a seed receiving box 61 for collecting spinning seeds, (a) the degree of contact is adjusted so that the tip of the rotating brush 47 is always located on the upper surface of the seed transfer groove 21; can be adjusted using the adjustment screw 63.

The seeds moving in the seed moving groove 21 are leveled evenly by the single-rotation brush 47.

C. Remove excess seeds (seeds that are not fitted into the fitting groove 19),
Since the rotation of the rotating brush 47 sweeps the grains back toward the starting end 22 side, each grain fits into the fitting groove 19 one by one, making it possible to perform accurate spot sowing.

2. In the above case, the seeds attached to the rotating brush 47 and rotating together can be collected in the seed receiving box 61.

Since most of the seeds that adhere to the rotary brush 47 are seeded seeds, it also serves as a seed sorter.

This effect is achieved.
