[Problems to be Solved by the Invention] With the above-mentioned conventional technology, there is no problem in sowing relatively large seeds such as rice, but it is difficult to sow seeds such as lettuce, cabbage, etc. that are small even if coated. When sowing 1 to 3 seeds at a time, the sowing roll is rotating, so if the recess is made small, it will be difficult for seeds to enter from the hopper. It has become difficult to accurately feed the drop while synchronizing it.

[0004] The method of the present invention involves intermittently transporting the seedling box, and in synchronization with this, linearly reciprocates a seeding board having seed holes to move it to a release position from which the seed holes have received seeds in the seed storage section. It is an object of the present invention to provide a seeding method for raising seedlings in which even relatively small seeds can be accurately sown by dropping the seeds from the seed hole at this detached position and sowing them.

[0005] Furthermore, in the device of the present invention, a seeding plate having a large number of seed holes is arranged at the bottom of the seed storage section, this seeding plate is supported by a fixed stand so as to be able to reciprocate in the direction of conveyance of the seedling box, and this fixed stand A seed drop opening is formed in the opening, a number of shoots are placed below the opening for guiding the seeds to the seedling box, and a seedling box transport mechanism is provided to intermittently transport the seedling box, and the multiple shoots are transported to the seedling box. To provide a seedling-raising sowing device capable of accurately and quickly sowing even relatively small seeds by dividing the seeds into multiple groups in multiple directions and simultaneously sowing into multiple rows of pot parts of a seedling-raising box.

Furthermore, in the device of the present invention, the number of seed holes in one row of the seeding board is set to be an integral multiple of the number of holes in one row of the pot part of the seedling nursery box, and the upper part of the multiple shoots can accommodate various holes. By placing the lower part in a position that can accommodate each pot section in multiple rows, seeds can be accurately stored in all seed holes under almost the same conditions even if the seeding plate moves in a short stroke. It is an object of the present invention to provide a seedling-raising seeding device that allows even relatively small seeds to be sown more accurately and quickly.

[0007]

[Means for Solving the Problems] A specific means for solving the problems in the method of the present invention is to linearly reciprocate the seeding plate 3 having the seed holes 2 for storing the required number of seeds 1, and to open the seed holes 2. The seeds 1 are moved from inside the seed storage section 4 that receives the seeds 1 to a release position, and at this release position, the seeds 1 are dropped from the seed hole 2 through the seed drop opening 6 of the fixed base 5 that supports the seeding board 3. The seedlings are sown through a chute 8 into a seedling raising box 7 which is intermittently transported.

The first concrete means for solving the problem in the apparatus of the present invention is that the seed storage section 4 is formed below the hopper 11, and the seed storage section 4 is arranged at the bottom of the seed storage section 4 to collect the required grains. A seeding plate 3 having a large number of seed holes 2 for storing seeds 1, a fixed base 5 that supports the seeding plate 3 so as to be able to reciprocate in the direction of transport of the seedling box, and a part of the fixed base 5 that corresponds to the seed storage section 4. A large number of chutes 8 are disposed below the seed drop opening 6 formed on the outside of the seedling box 7 and are divided into multiple groups in the direction of transport of the seedling box 7 in order to guide the seeds 1 to the plurality of rows of pot portions 9 of the seedling box 7. , a seedling box transport mechanism 15 that intermittently transports the seedling box 7;
From the time the seedling raising box 7 is brought in until the time it is taken out, the seeding plate 3 is driven to reciprocate the seed hole 2 from the inside of the seed storage section 4 to the position corresponding to the seed drop opening 6 in synchronization with the transportation of the seedling raising box 7. The seed plate driving mechanism 16 is provided.

Furthermore, a second specific means for solving the problem in the apparatus of the present invention is, in addition to the first specific means of the apparatus, that the large number of seed holes 2 of the seeding board 3 are arranged so that the number of seedlings in one row is box 7
The number of chutes 8 is set to be an integral multiple of the number of pot sections 9 in one row, and the upper portions of the multiple chutes 8 are arranged in positions that can accommodate various holes 2, and the lower portions are arranged in positions that can accommodate each of the plurality of rows of pot sections 9, respectively. It is located in

0010

[Operation] When the seeding plate 3 is reciprocated on the fixed table 5 in the direction of transporting the seedling box through the seeding plate drive mechanism 16, a large number of seed holes 2
enters the seed storage section 4 formed below the hopper 11, and stores the required number of seeds 1. Since the large number of seed holes 2 move in a straight line and stop momentarily when switching from forward movement to backward movement, the seeds 1 are stored accurately.

[0011] The seeding plate 3 moves back and the seed hole 2 is fixed to the fixed base 5.
When the seed storage part 4 is moved to a position facing the seed drop opening 6 formed on the outside of the corresponding part, the lower part of the seed hole 2 is opened and the seeds 1 fall. At this time as well, the sowing plate 3 momentarily stops because the direction of movement is reversed, and the seeds 1 are reliably discharged. A large number of seed holes 2 are arranged in one row, and when entering the seed storage section 4 and leaving the seed storage section 4, the seeds 1 are stored in all the seed holes 2 under the same conditions, and the seeds 1 are stored in the seed holes 2 under the same conditions. The seeds 1 discharged from the seedling box 2 enter the upper part of multiple chutes 8 at the same time, and since the shoots 8 are divided into multiple groups in the direction of transporting the seedling box, the seeds 1 are delivered to the seedling box 7 which is intermittently transported by the seedling box transport mechanism 15. Multiple rows are supplied for rapid seeding.

The engaging recess 55 is swung in the direction of detaching from the pin 57.

A tension spring 49 is provided between the sowing plate 3 and the fixed base 5 to assist the return movement of the sowing plate 3. Therefore, the slider 19 mainly serves to move the seeding plate 3 forward, and when the clutch pawl 20 is disengaged, the seeding plate 3 is held in a state where the seed holes 2 are located in the seed storage section 4. the motor M, the slider 19, the clutch pawl 20,
The solenoid 21, the tension spring 49, and the like constitute the seeding plate drive mechanism 16.

On the outside of the device frame 40, there is a transport device B.
A seedling-growing box transport mechanism 15, which constitutes a part of the container, is arranged. The seedling box conveyance mechanism 15 is driven by a motor M, and includes a pair of interlocking rods 61 supported on the outer surface of the side wall 41 via rollers 60 so as to be able to move back and forth, and a front end installed between the left and right interlocking rods 61. A frame-shaped movable body 17 is constituted by one support rod 62 and two rear support rods, and each support rod 62 has a pair of left and right engaging claws 1.
8 is swingably provided. Two guide rails 68 are provided on the machine frame 30 via a mounting plate 67, so that the seedling growing box 7 can be transferred from the first belt conveyor 33. A position setting plate 69 is fixed to the support rod 62 for setting the lowest position of the engaging claw 18 so that it does not hang down.

A rotating shaft 63 is supported on the device frame 40, and a gear 64 provided at one end of this rotating shaft 63 is connected to a motor M.
A disk 65 provided at the other end is connected to the interlocking rod 61 via a crank rod 66. Therefore, when the motor M rotates, the interlocking rod 61 is linearly reciprocated back and forth, and all the engaging claws 18 are driven back and forth.

[0026] The left and right engaging pawls 18 are oriented forward and downward,
It can be freely engaged with and detached from the pot portions 9 on the left and right sides of the cell tray 32, and when moving forward, it engages with the pot portion 9 to raise the seedling box 7 into two.
It moves forward by a stroke corresponding to the pot part 9 of the row, and when moving backward, it only slides on the upper surface of the cell tray 32, thereby intermittently transporting the seedling box 7. A detection means 22 is provided on the device frame 40 and the machine frame 30, and this detection means 22 includes three sensors 23 and 24.
, 25. The first sensor 23 is the closest to the carrying direction (
(at the rear), the transfer of the seedling box 7 to the seeding device H is detected and the motor M is activated. The second sensor 24 is located near the chute 8 and excites the solenoid 21 of the seeding board drive mechanism 16 by detecting the seedling raising box 7.

The third sensor 25 is connected to the first and second sensors 23 and 2.
4, to prevent rear-end collisions with subsequent seedling raising boxes 7. That is, the third sensor 25 is ON when detecting the seedling raising box 7.
, and the operation of the motor M is maintained even if the first sensor 23 is turned off. However, when the supply of the seedling growing box 7 is interrupted and the first sensor 23 is turned off, and the third sensor 25 is removed from the rear end of the last seedling growing box 7 and turned off, the motor M stops. Next, a new seedling raising box 7
When the motor M is carried in and the first sensor 23 turns ON, the motor M
is activated, and the seedling box transport mechanism 15 is driven. At this time, even if the engaging claw 18 is in the return stroke and the seedling growing box 7 cannot be sent immediately, two sensors 23 and 25 are installed between the tip of the new seedling growing box 7 and the rear end of the last seedling growing box 7. A gap set by the interval is formed, and the new seedling growing box 7 is the last seedling growing box 7.
Rear-end collision is avoided.

Next, a series of operations in seeding machine A will be explained. A cell tray 32 is inserted into the outer box 31 to form a seedling growing box 7, and this is placed on the first belt conveyor 33 of the transport device B and transported. The seedling raising box 7 to be transported first passes through a bed soil device C, is supplied with the required amount of bed soil, and is moved by a pressing roller D.
After the soil is compacted, the excess soil is removed by a scraper E that comes into sliding contact with the upper surface of the cell tray 32, and then the bed soil volume is optimized by a bed soil brush F.

The seedling raising box 7 containing a predetermined amount of bed soil enters the seeding recess forming device G while being conveyed by the first belt conveyor 33, and passes through the protrusion on the outer periphery of the patterning roller 34 which rotates in synchronization with the conveyance speed. 35, a seeding recess 36 of a required depth is continuously formed in the center of the soil bed of each pot portion 9. Thereafter, the seedling raising box 7 is sent to the entrance of the seeding device H by the first belt conveyor 33 and transferred onto the guide rail 68. In the seeding device H, the first sensor 23 detects the introduction of the seedling growing box 7, and the motor M is activated to operate the seedling growing box transport mechanism 15 and the seeding board drive mechanism 16. The seedling raising box 7 is intermittently fed by two pitches by the engaging claw 18 of the seedling raising box conveying mechanism 15. When this seedling raising box 7 reaches a predetermined position in the seeding device H, that is, a seeding position, the second sensor 24 detects this and excites the solenoid 21 of the seeding board drive mechanism 16.

In the seeding plate drive mechanism 16, a slider 19 is reciprocated by the power from the motor M, and a clutch pawl 20 provided on the slider 19 is activated by the excitation of a solenoid 21, and the seeding plate 3 It moves to the side and engages with the pin 57 on the seeding plate 3, thereby moving the seeding plate 3 together with the slider 19. The seeding plate 3 reciprocates on the fixed base 5, and moves a large number of seed holes 2 formed in one horizontal row from the inside of the seed storage section 4 to a release position. The seed storage section 4 is located below the hopper 11 and stores a large amount of seeds 1.
When the seed holes 2 enter this interior, the seeds 1 are stored in all the seed holes 2 under substantially the same conditions. At this time, the sowing plate 3 stops momentarily because the moving direction changes. When the seed hole 2 passes below the partition member 12 in order to escape from the seed storage section 4, or because the seeding board 3 has tilted forward and upward by then, the surplus seeds 1 are removed and the seeds are seeded. The required number of seeds 1 remains in the hole 2.

A large number of seed holes 2 are all removed from the seed storage section 4 at the same time to face the seed drop opening 6 of the fixed base 5 that supports the seeding plate 3. The seeds 1 stored in all the seed holes 2 fall from the seed holes 2 through the seed drop openings 6 and enter into a large number of chutes 8. At this time as well, the sowing plate 3 stops momentarily because the direction of movement changes. Each shoot 8 is arranged in one row so that its upper part can face all the seed holes 2, but its lower part is divided into two rows (multiple groups) in the direction of conveyance of the seedling box, in which seeds 1 are placed in one horizontal row. Seedling raising box 7 is divided into two groups, front and rear, and transported intermittently.
Seeds are simultaneously sown into the seeding recesses 36 of the two rows of pot sections 9. When the seeding plate 3 releases the seeds 1, it is moved back by the slider 19 and the tension spring 49, and returns to the seed storage section 4, where new seeds 1 are stored.

[0032] After seeding, the seedling raising box 7 is transferred to the second belt conveyor 3.
7, the irrigation device J supplies the required amount of water and chemicals, and the soil covering device K supplies soil to cover the soil, and the soil surface is leveled. The seedling growing boxes 7 are continuously carried into the seeding device H, but if the feeding is interrupted for some reason, the first sensor 23 is turned off, but the third sensor 25 detects the rear end of the last seedling growing box 7. The motor M is driven until it is detected, and stops when the third sensor 25 is turned off. Then, when a new seedling growing box 7 is brought in next time, there is a gap between the two sensors 23 and 25 between the tip of the new seedling growing box 7 and the rear end of the last seedling growing box 7. A set gap is formed, and the new seedling growing box 7 is prevented from colliding with the last seedling growing box 7.

It should be noted that the present invention is not limited to the embodiments described above, and can be modified in various ways. For example, the seeding plate 3 is tilted forward and upward in order to remove excess seeds placed thereon from above the seed hole 2 in front of the front partition member 12;
This may be horizontal, the seed holes 2 may be in one row, but they may be arranged in two or more rows, or the shoots 8 may be divided into three or more groups in the direction of transport of the seedling box. box 7
The feed pitch is also set to 3 pitches or more accordingly. In addition, the seedling raising box 7 can be prepared by inserting a paper pot into the outer box 31,
A lattice-like partition plate may be provided to partition the interior.

[0034]

According to the method of the present invention described in detail above, the seeding plate 3 having the seed holes 2 is reciprocated in a straight line while the seedling raising box 7 is being conveyed intermittently, and the seed holes 2 are removed from the seed storage section 4. It moves to the detachment position, receives the seeds 1 in the seed storage section 4, drops the seeds 1 at the detachment position, and sows the seeds through the chute 8.
Even relatively small seeds can be sown accurately.

According to the device of the present invention, the seed storage section 4 is formed below the hopper 11, and the seeding plate 3 having a large number of seed holes 2 is disposed at the bottom of the seed storage section 4. 3 are supported by a fixed stand 5 so as to be able to reciprocate in the direction of transporting the seedling box, a seed drop opening 6 is formed in this fixed stand 5, and a number of chutes 8 for guiding the seeds 1 to the seedling box 7 are arranged below the opening 6. Since a seedling box transport mechanism 15 for intermittently transporting the seedling box 7 is provided, and the plurality of shoots 8 are divided into groups in the direction of transport of the seedling box, even relatively small seeds can be sown accurately and quickly.

Furthermore, according to the device of the present invention, the number of seed holes 2 in one row of the seeding plate 3 is set to be an integral multiple of the number of holes in one row of the pot portions 9 of the seedling raising box 7, and a large number of shoots 8 are arranged. The upper part is placed in a position that can accommodate the various holes 2, and the lower part is placed in a position that can accommodate each of the plurality of rows of pot parts 9, so even if the seeding plate 3 moves in a short stroke, all the seed holes will be covered. Seeds 1 can be accurately stored in the container 2 under substantially the same conditions, and even relatively small seeds can be sown more accurately and quickly.
