Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sowing seeds such as non-spherical vegetables, and more particularly to an apparatus for sowing honeybee seeds.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open No. 63-237708 discloses a supply hopper for storing and supplying seeds at a position above a transfer table for laterally transferring a storage box containing a polypot (trade name). In a sowing device provided with a seeding plate having a seeding hole provided below the supply hopper and a shutter for dropping seeds fitted in the seeding hole, the seeding plate also serves as a bottom plate of the supply hopper. , The seeding plate is composed of two plates, an upper plate and a lower plate, and the shutter is movably provided between the upper plate and the lower plate.

[0003]

However, as compared with the seeding device using the feeding roll having the feeding recess formed on the outer peripheral surface, the seeding by the combination of the seeding plate and the shutter is fixed at a certain position as in the known example. Although there is an advantage that seeds can be sown accurately because the seeds are dropped, there is a problem that the seeds are clogged when the seeds are located in the middle of the through holes of the seeding plate and the shutter. Since the upper plate and the lower plate are also used as two sheets and the shutter is provided between the upper plate and the lower plate, the two plates pass through the matching through holes of the upper plate and the shutter and the shutter and the lower plate. There is a high possibility that it will get stuck. In particular, crescent-shaped non-spherical seeds such as honeybee seeds cannot be sown because they may be crushed when the shutter moves because the state of fitting into the through holes is not constant. Further, since the seeds that have entered the through holes of the shutter are carried to above the through holes of the lower plate while being fitted into the through holes of the shutter, the seeds are crushed or damaged significantly, and the germination rate decreases. From this point as well, non-spherical seeds cannot be sown because the orientation is often changed and jammed during movement. Therefore, there is also a problem that the portion where seeds are clogged becomes a missing strain and the seeding accuracy is significantly reduced. In addition, the seeds of honey are
If the seeds are sown over the seedbed, the growth will be poor and the commercial value will be significantly reduced. Therefore, ideally, a seeded state in which a predetermined amount of seeds are sown in each block of the nursery, and the various seeds are not polymerized is good.

[0004]

It is an object of the present invention to allow a predetermined amount of seed to be sown in each block of a nursery bed without being polymerized.

[0005]

Therefore, according to the present invention, a storage box 4 into which a seedbed 1 made of a flat plate-shaped sponge, in which blocks 2 which can be divided by slits 2 are formed at predetermined intervals in the vertical and horizontal directions, can be fitted.

In the figure, 77 is a watering device, and 81 is a recovery part.

[0018]

[Operation] Next, the operation will be described. Switch group 8 of control panel 76
0 main switch is turned on, standby position switch 72
Is ON, the box-shaped frame 49 is in the standby position, and when the switch 78 is ON, the shutter 38 is in the closed state. Therefore, the control panel 76 (meaning a control unit) energizes the feeding motor 27. The feeding roll 22 is rotated so that the seed in the supply hopper 21 is fitted into the feeding recess 23 of the feeding roll 22 and passes under the sliding brush 24 into the seed guide 30. The number of teeth 26a of the gear 26 of the feeding roll 22 passing through the detection unit 20 is counted, and when the feeding roll 22 rotates by a set amount, the feeding motor 27 is de-energized to stop the rotation of the feeding roll 22. The seed that has entered the seed guide 30 flows down into the drop guide guide 31 by its own weight, and the seed that drops from the drop guide guide 31 is supplied to the drop chute 50 of the moving seed supply unit 45 and temporarily stored, and the feeding motor is used. After a lapse of a predetermined time after the stop of 27, the control board 76 energizes the moving motor 58 and the brush rotating motor 52 to move the moving motor 58.
Rotates the front gear 56 to move the lower chain 57 in the direction of arrow a.

By moving the chain 57, the moving seed supply unit 4
The box-shaped frame 49 of No. 5 moves in the arrow A direction with the guide rollers 60 and 62 on the left and right sides of the box-shaped frame 49 engaged with the guide rails 61 and 61 provided on the left and right sides of the seeding plate 36. , Box frame 49 and drop chute 5
0 moves. While the drop chute 50 stands by below the payout roll 22, a small amount of seeds flow down into the gap between the lower end of the drop chute 50 and the upper surface of the sowing plate 36, and the seeds cause the drop chute 50 to fall. The lower end of the drop chute is blocked and does not flow down any more.
When starts moving in the direction of arrow A, a gap is formed again between the lower end of the drop chute 50 and the upper surface of the sowing plate 36, so that the seeds in the drop chute 50 flow down to the upper surface of the sowing plate 36. Therefore, the drop chute 50 moves to uniformly supply seeds from one end to the other end of the sowing plate 36.

In this case, on the upper surface of the sowing plate 36 between the sowing holes 35 in each of the adjacent left and right columns, a seed guide body 37 having a triangular cross section whose width becomes narrower as it goes upward is provided. Therefore, the seeds flowing down from the drop chute 50 are distributed by the seed guide body 37 to the vertical rows of the right and left seeding holes 35, and thus are uniformly supplied. Further, since the seed guide body 37 is formed in a triangular cross-section whose lateral width becomes narrower as it goes upward, the drop chute 50
The seeds that have flowed down are guided by the slopes of the seed guide body 37 to the seeding holes 35 located at the center, and are securely fitted into the seeding holes 35. Then, the rotation leveling brush 5 rotated by the brush rotation motor 52 provided in the box-shaped frame 49.
1 moves while sweeping the seeds that have not been fitted into the seeding holes 35 among the seeds that have fallen to the front side (the starting end side of the transfer table 10) in the movement direction. Also in this case, since the seed guide body 37 is provided between the sowing holes 35 in each of the columns that are adjacent to each other on the left and right, the seeds swept by the rotary leveling brush 51 are sowed by the seed guide bodies 37 in the columns that are adjacent to each other. Since it does not move to the group 35 side, seeds can be uniformly supplied to the group 35 of sowing holes in each column, and uniform seeding can be performed. Then, the box-shaped frame 49 reaches the intermediate position A which is the rearmost part of the seeding hole 35 of the seeding plate 36.
Is moved, the box-shaped frame 49 moves the intermediate switch 73
Then, the control board 76 reverses only the brush rotation motor 52 to reversely rotate the rotary leveling brush 51, and the rotary leveling brush 51 does not form the seeding hole 35 in the rear portion of the seeding plate 36 in this state. Move to the non-hole portion 70. Therefore, the rotating and leveling brush 51, which has been swept to the non-hole portion 70 side until now, moves toward the non-hole portion 70 while returning to the supply hopper 21 side.

The box-shaped frame 49 is provided at the end of the non-hole portion 70.
When the box position is reached, the box-shaped frame 49 turns the return position detection switch 7
4, the control board 76 reverses the moving motor 58, moves the box-shaped frame 49 in the arrow B direction toward the standby position below the feeding roll 22, and ignores the intermediate switch 73. When 49 returns to the standby position, the standby position switch 72 is turned on, and the control board 76 stops the brush rotation motor 52 and the movement motor 58. Therefore, the rotary leveling brush 51 has the non-perforated portion 7 in the forward stroke.
The seeds that have been swept up to 0 are swept back in the return path, and are flattened again when returning, so that the seeds are securely fitted into the sowing holes 35. Then, the rotating and leveling brush 51 that has returned to the standby position skips and collects the excess seed to the collecting unit 81 provided on the front side of the seeding plate 36.

Thus, while the seeds are being supplied to the sowing holes 35 of the sowing plate 36, the front transfer table 1 of the transfer table 10 is provided.
The storage box 4 fitted with the sponge seedbed 1 (which may or may not already absorb water) supplied to the starting end portion of 1 is transferred by the transfer roll 13 rotated by the front transfer motor 14. When moving forward and the tip of the storage box 4 reaches a predetermined position below the supply hopper 21, the stop position switch 75 is turned on to stop the operation of the front side transfer motor 14 and move the storage box 4 to the predetermined position. The control panel 76 energizes the solenoid 67 when the standby position switch 72 is turned on by the box-shaped frame 49 returned to the standby position, the solenoid 67 pulls the shutter 38, and the seeding plate 36 is completely seeded. The seeds fitted in the holes 35 are
The seeds are sown on the upper surface of each block 3 of the sponge nursery 1 waiting downward through the drop opening 41 of the shutter 38, and the control panel 76 energizes the solenoid 68 when the switch 78 is turned on by opening the shutter 38. And shutter 38
To the closed position.

In this case, the drop opening 41 of the shutter 38
Since the diffuser 32 is provided below the diffuser 32 at a predetermined interval, the seeds above the peripheral edge of the diffuser 32 fall around the center of each block 3 as it is, but the diffuser 32 The seeds in the drop port 41 above the ‘1’ drop once on the diffuser 32 and bounce to fall on the block 3. Therefore, the seeds dropped from the drop opening 41 are diffused by the diffuser 32 and are not sown in the center of the block 3 of the sponge seedbed 1, but fall around the center of the block 3.
Therefore, during seedling germination and growth, sufficient ventilation and sunshine between seedlings can be secured, good cultivation can be performed, and when harvested, the stems of each block 3 have the same thickness and thin yellowish stems. Since it does not exist, it has high commercial value, and it reduces the burden of pretreatment before shipping to remove thin yellowed stems.

When the switch 79 is turned on by the return of the shutter 38, the control panel 76 energizes the front transfer motor 14 to start the transfer of the storage box 4, and the switch 79 resets the shutter 38. Box frame 49
Is detected by the standby position switch 72, the feeding motor 27 is energized again, and seeds are supplied to the seeding holes 35 of the seeding plate 36 until the storage box 4 reaches the predetermined position. In the above case, when the drop hole 41 of the shutter 38 is aligned with the seed hole 35 of the seed plate 36, the seed drops, so the seed hole 35 and the drop port 4 are provided.
Since there is no movement of seeds as in the known example in 1, the seeds are not clogged and the seeds are not damaged. Therefore, not only ordinary seeds having a spherical shape, but also coated seeds and seeds having a non-spherical shape such as honeywort and leeks can be satisfactorily sown. Further, the shutter 38 has a long hole 44 which is long in the moving direction of the shutter 38, and the bolt 39 is inserted into the long hole 44 from above the seeding plate 36 to suspend the shutter 38. It is attached to the seeding plate 36.

The movement of the shutter 38 is carried out by the shutter 3
Since the elongated hole 44 of No. 8 is guided and regulated by the bolt 39 fixed to the sowing plate 36, the moving direction becomes constant, and the drop opening 41 of the shutter 38 surely matches the sowing hole 35 to surely drop the seeds. .. Further, a spring 40 is provided on the outer circumference of the bolt 39, and the spring 40 urges the upper surface of the shutter 38 to closely contact with the lower surface of the seed plate 36. Therefore, the drop opening 41 of the shutter 38 and the seed hole 35. Make sure to drop the seeds without any gap between them. Further, since the drop opening 41 of the shutter 38 is formed in a hole larger than the seeding hole 35 of the seeding plate 36, the seed can be dropped more favorably. Further, since the solenoid 67 shock-pulls the shutter 38 and the solenoid 68 shock-returns to the original position of the closed state, not only the seeds in the drop opening 41 but also the diffuser 32 and the connecting body 33 are struck. Be sure to drop the seeds that are riding on. Then, the seeded storage box 4 is transferred to the rear transfer table 12, is watered by the irrigation device 77, and is taken out at the terminal end of the transfer table 10. The removal of the storage box 4 fails and the storage box 4 is switched. When it comes into contact with 82, all devices including the irrigation device 77 are stopped. The sponge seedbed 1 taken out at the end of the transfer table 10 germinates after a few days, so it is divided into blocks 3 and fitted into the fitting holes of a foamed polystyrene seedbed about the size of one tatami mat. Raise seedlings, harvest and ship. Further, in this embodiment, since the excess seeds are leveled and removed by the rotary leveling brush 51, it is possible to supply more seeds than the amount to be sown to the moving seed supply unit 45, and surely all the seeds are seeded. The seeds are fitted in the sowing holes 35 to prevent the occurrence of stockout.

[0026]

According to the present invention, the transfer table 10 for laterally transporting the storage box 4 into which the seedbed 1 made of a flat plate-shaped sponge, in which the blocks 3 are formed by forming the cuts 2 at predetermined intervals in the vertical and horizontal directions, can be fitted. And a seed hopper 21 for storing seeds provided above the transfer table 10 and seeding holes 35 which are fixed to the transfer table 10 at a lower position of the supply hopper 21 and are arranged side by side at predetermined intervals. The seeding plate 36, a shutter 38 for dropping seeds fitted in the seeding holes 35 that overlap the lower surface of the seeding plate 36, and the supply hopper provided between the lower part of the supply hopper 21 and the seeding plate 36. In the seeding device comprising a drop chute 50 for supplying the seeds in 21 to the sowing holes 35 of the sowing plate 36, and a brush 51 which moves with the drop chute 50 to level the surface of the sowing plate 36, Shhh Between each of the drop openings 41 of 38 and the seedbed 1, a diffuser 32 for diffusing the seeds dropped from the drop openings 41 so as to sow around the center of the block 3 of the seedbed 1 while avoiding the center of the block 3. Since the seeding device is provided, the seeds other than above the diffuser 32 among the fixed amount of seeds corresponding to each block 3 of the seedbed 1 fitted into the seeding holes 35 of the seeding plate 36 are: The seeds above the diffuser 32 fall once while avoiding the center of each block 3 and once the diffuser 32
Since the seeds are spread by and fall down avoiding the center, the seeds are sown around the blocks 3 avoiding the center thereof, and ventilation and sunshine between the seedlings are sufficiently secured, and there is an effect that it can be cultivated satisfactorily. In addition, since the ventilation between the seedlings and the sunshine are sufficiently secured and good cultivation is possible, the stems of each block 3 have the same thickness when harvested, and there is no thin yellowish stem, so that the commercial value is high. Also, the effect of reducing the burden of pretreatment before shipping to remove yellowed thin stems can be expected.

Claims (1)

[Claims] 1. A transfer table 1 for laterally transporting a storage box 4 into which a seed bed 1 made of a flat plate-shaped sponge, in which cuts 2 are formed at predetermined intervals in vertical and horizontal directions to form a separable block 3, is fitted.
0, a feed hopper 21 for storing seeds provided above the transfer table 10, and seeding holes 35 which are fixed to the transfer table 10 at a lower position of the supply hopper 21 and arranged at predetermined intervals side by side in the front-rear and left-right directions. Seeding plate 36, a shutter 38 for dropping the seeds fitted in the seeding holes 35 which are superposed on the lower surface of the seeding plate 36, a lower part of the supply hopper 21 and the seeding plate 3
6 and a drop chute 50 that supplies seeds in the supply hopper 21 to the sowing holes 35 of the sowing plate 36, and moves with the drop chute 50 to level the surface of the sowing plate 36. In the seeding device including the brush 51, between the respective drop openings 41 of the shutter 38 and the seedbed 1, the drop openings 41 are arranged so as to avoid seedling around the center of the block 3 of the seedbed 1 and avoid the center of the block 3. A seeding device provided with a diffuser 32 for diffusing more dropped seeds.
