Reference numeral 32 denotes a seed guiding groove formed on the upper surface of the shutter 30, and the seed fitting hole 31 is formed at the groove bottom of the seed guiding groove 32.
The width of the seed guiding groove 32 is at least the same as that of the seed 20,
Even if the depth of the seed guiding groove 32 is deep, the seed guiding groove 32 is formed to be the same as the seed 20 so that the seeds 20 can be fitted in a line. The lower end of the leveling brush 27 faces the seed guiding groove 32. A pair of front and rear engagement legs 34, 35 protruding downward is formed on one of the left and right sides of the shutter 30, and the engagement legs 34, 35 are formed.
Is a moving shaft 3 in the front-back direction for moving the shutter 30 back and forth.
6 is detachably engaged from above. The moving shaft 36 is rotatably supported by the front plate 37 and the rear plate 38 of the seeding section 23 so as to be movable back and forth.
A washer 39 is attached to the front end portion of the moving shaft 36 projecting forward from the front plate 37, and a spring 40 is provided between the washer 39 and the front plate 37. Moving shaft 3 inside the front plate 37
A stopper 41 is provided at a predetermined position of 6, and the shutter 3
A washer 42 is fixed to the moving shaft 36 between the engaging leg 34 and the engaging leg 35 of 0, and a spring 43 is provided between the washer 42 and the engaging leg 35. A washer 44 is fixed to the moving shaft 36 between the engaging leg 35 and the rear plate 38.

A left and right engaging shaft 47 is fixed to the rear end portion of the moving shaft 36, and both ends of the engaging shaft 47 are inserted into elongated holes 48 formed in the frame 24. An engagement member 49 that engages and disengages with the engagement shaft 47 at a predetermined position is provided near the engagement shaft 47. The rear end of the engaging member 49 is fixed to the rotating frame 50, and the rotating frame 50 is a horizontal shaft 51 axially attached to the frame 24.
Only the rotation can be freely stopped. The movement of the seeding section 23 (hopper 26 and bottom plate 28) and the shutter 30 will be described. The rotation of the front and rear cranks 25 causes the whole seeding section 23 to move circularly (counterclockwise in the figure), and the moving shaft 36 has its rear end. When the engaging member 49 engages with the engaging shaft 47 of, the position of the moving shaft 36 is immovable with respect to the seeding section 23 (the engaging shaft 4).
If the engaging member 49 is not engaged with 7, the moving shaft 36 moves together with the seeding portion 23 due to the action of the spring 40). As a result, when the seeding section 23 starts descending from the uppermost position (12:00 of the clock) (FIG. 11), the seeding section 23 and the hopper 26 are
It moves rearward with respect to the moving shaft 36 and the shutter 30 (movement is blocked by the washer 44) (FIG. 13),
The leveling brush 27 moves and retracts from above the seed fitting hole 31, the seed fits into the seed fitting hole 31, and the seed is fitted into the horizontal position (9 o'clock on the clock).
When the seeds are moved further to the front, the discharge port 29 is aligned with the seed fitting hole 31 to drop the seed. A regulating member 52 is provided on the rear plate 38 of the seeding section 23 in order to position the seed fitting hole 31 below the leveling brush 27 after dropping the seed.

An upper end of a hose 55 is detachably connected to a lower portion of each of the outlets 29, and a lower end of the hose 55 has a lower end of the seeding section 2.
3 is connected to the drop port 57 of the seeding plate portion 56 provided in the lower part. The drop openings 57 are formed at the same intervals as each of the pots 1 described above. On the rear side of the seeding plate portion 56, a pressing plate portion 59 having a group of pressing protrusions 58 is integrally formed. The pressing protrusion 58 forms a concave portion 60 on the upper surface of the floor soil 4 of the pot 2 and seeds the concave portion 60. Therefore, the transfer device 5 below the frame 24 has a transfer mechanism 6 for seeding.
5 is provided. The transfer mechanism 65 includes a seeding transfer piece 66 that transfers the seedling-growing mat 1 in synchronization with the moving speed of the seeding section 23, and a feed transfer piece 67 that transfers the seedling-growing mat 1 to the seeding transfer piece 66. Transfer pieces 66, 6
7, a base shaft cylinder 70 is rotatably attached to the shafts 68 and 69 and is rotatably mounted so that the tips of the transfer pieces 66 and 67 are positioned downward by their own weight. Underneath 66 and 67, transfer piece 6
The tips of 6, 67 are engaged with the inner wall of the pot 2 for transfer. A projecting piece 85 is fixed to the tips of the transfer pieces 66 and 67, and a through hole 86 is formed in the projecting piece 85. The step between the transfer pieces 66, 67 and the projecting piece 85 securely engages with the inner wall of the pot 2, and the floor soil 4 escapes from the through hole 86 to prevent clogging.

The shafts 68 and 69 are engaged with the guide holes 71 formed in the frame 24 in the front-rear direction, and the rear ends of the rods 72 and 73 are attached to the portions projecting from the guide holes 71, respectively. The front end of the rod 72 is pivotally attached to the seeding rotary disc 74. The radius of the sowing rotary disc 74 is the same as the length of the crank 25, and the moving speed of the sowing transfer piece 66 and the moving speed of the sowing section 23 are matched. The front end of the rod 73 is pivotally attached to the feed rotary disc 75,
By changing the length of the rod 73 and the mounting portion of the feeding rotary disk 75, the feeding speed of the seedling raising mat 1 by the feeding transfer piece 67 is adjusted. That is, since the seedling raising mat 1 is commercially available in several types with different intervals between the pots 2, the seeding transfer piece 66 and the feed transfer piece 6 are provided.
7 and 7 are reciprocally moved in opposite directions, so that at a certain point, the feeding transfer piece 67 can take over the seeding transfer piece 66.
This is handled by changing the moving speed of the feed transfer piece 67 until the transfer.

In FIG. 25, S is the feed start point of the feed transfer piece 67, and T is the feed transfer piece 67 and the seeding transfer piece 6.
6 is a transfer point where the tip end coincides with 6, and G is a seeding point at which the seeding transfer piece 66 advances the seedling mat 1 to sow.
Then, the number of sowing times by the sowing section 23 is arbitrarily set with respect to the total number of pots 2 of the seedling raising mat 1 and divided by the set number of sowings to obtain the number of pots 2 to be sowed at one time. The interval from the first pot 2 to the last pot 2 and the seeding interval C are matched. For example, crank 25
In the case of the seedling raising mat 1 having a length of 40 mm, 20 pots and an interval of 25 mm, when seeding four pots 2, the number of seeding is 5 and the seeding interval C is 100 mm. Since the synchronous sowing interval A is 40 mm, the feed interval B is 60 mm, which is 18 and the interval is 25.
In the case of the seedling raising mat 1 having a pot 2 of mm, when sowing three pots 2, the number of seeding is 6, the sowing interval C is 75 mm, and the synchronous sowing interval A is 40 mm.
Therefore, the feed interval B is 35 mm. As the seeding plate portion 56 and the pressing plate portion 59, several kinds of dropping ports 57 and pressing protrusions 58 having different numbers and intervals are prepared and used in exchange (for example, when there are 20 pots, 4).
The seeding plate portion 56 and the pressing plate portion 59 of the individual drop openings 57 and the pressing projections 58 are used, and the seeding plate portion 56 and the pressing plate portion 59 of the three drop openings 57 and the pressing projections 58 are used when the number is 18. To do. )

Reference numeral 61 is a motor, 62 is a gear, 63 is a shaft, 6
4 is a gear, 76 is a transfer roller 77 on the starting end side of the transfer device 5, the automatic supply device 6 and the soil supply device 8
A stop switch for stopping these, 78 a start switch for activating them, 79 a shaft, 80 a gear, 81 a shaft, 82
Is a chain. The seeding transfer piece 66 and the feed transfer piece 67 are transferred faster than the transfer roller 77. Since the shutter 30 is opened and closed only when the engaging member 49 is engaged with the engaging shaft 47 of the moving shaft 36, the rear end of the support arm 90 is attached to the horizontal shaft 51 to which the engaging member 49 is attached. The shaft is stopped, and a sensing roller 91 is provided at the front end of the support arm 90. When the sensing roller 91 comes into contact with the upper surface of the side edge of the seedling raising mat 1, the engaging shaft 47 of the moving shaft 36 engages with the engaging member 49.
When the seedling-growing mat 1 is not present, the sensing roller 91 descends, the support arm 90 does not rotate, and the engaging member 49 retreats to a position where the engaging shaft 47 does not engage. As a result (clutch disengagement), the relative movement of the shutter 30 and the bottom plate 28 is not performed, and seeding is not performed. A manual switching device 92 is provided at a desired position of the support arm 90 so that the support arm 90 can be manually moved up and down to manually engage and disengage the clutch. Reference numeral 93 is a cover soil supplying device, 94 is a brush, 95 is an irrigation device, and 96 is an extracting device. In addition,
The transfer roll 7 is provided on the transfer device 5 on the rear side of the seed supply device 22.
7 is provided.

[Operation] Next, the operation will be described. When the seedling-growing mat 1 is supplied to the transfer table 5, the soil is supplied by the bed soil supply device 8 to reach below the scraper 9, and the scraper 9 is one of the floor soils 4 supplied on the seedling-growing mat 1. The floor soil 4 is left above the pot 2 by the notch portion 12, and the floor soil 4 on the upper surface 14 of the seedling-growing mat 1 between the pots 2 is removed by the scraping portion 13. Therefore, the compression roller 15
Put the soil 4 above the pot 2 on the seedling mat 1
Since it can be compressed as much as possible to the upper surface position, the soil floor 4 in the pot 2 is reliably suppressed. The seedling-growing mat 1 that has passed below the compression roller 15 can be pressed into the pot 2 by the elastic leveling brush 16 into the pot soil 2 on the upper surface 14 of the seedling-growing mat 1 between the pots 2. Excessive soil is removed by the rotating and leveling brush 17, and the supply of the floor soil 4 is completed.

When the tip of the seedling-growing mat 1 comes into contact with the stop switch 76, the rotation of the transfer roller 77 is stopped, and the seedling-growing mat 1 is at this point (feed start point S).
Wait at. On the other hand, the rod 73, which is moved backward by the rotation of the feeding rotary disc 75, moves the feeding transfer piece 67 backward, and the feeding transfer piece 67 is on standby.
It engages with the inner wall of the first pot 2 at the feed start point S to start the forward movement (when the tip of the seedling-growing mat 1 comes into contact with the start switch 78, the transfer roller 77 is rotated again). When the feeding transfer piece 67 starts to move forward,
The sowing transfer piece 66 starts to move backward, and the sowing transfer piece 66
And the tip of the feeding transfer piece 67 are coincident at the transfer point T,
The sowing transfer piece 66 continues to advance the seedling raising mat 1 from the takeover point T. Since the crank 25 for moving the seeding unit 23 and the diameter of the seeding rotary disc 74 of the seeding transfer piece 66 are the same, the transfer speed of the seeding transfer piece 66 and the transfer speed of the seeding section 23 are the same. The upper surface of the pot 4 of each pot 2 of the seedling-growing mat 1 is pressed by the pressing protrusions 58 of the pressing plate portion 59 that gradually descends due to the circular movement.

On the other hand, the seed feeding device 22 includes the crank 2
5. Since the seeding section 23 is repeatedly moved circularly via the crank 25, the seeds 20 are being moved while the drop opening 57 formed in the seeding plate section 56 at the lowermost end of the seeding section 23 is being matched with the pot 2. Can be seeded by dropping. That is, when the front and rear cranks 25 rotate, the whole seeding section 23 moves circularly (counterclockwise in the figure), and when the engaging member 49 engages with the engaging shaft 47 at the rear end of the moving shaft 36, the moving shaft 36 moves. Since the position is immovable with respect to the sowing section 23, when the sowing section 23 starts descending from the uppermost position (12:00 of the clock) (FIG. 11), the sowing section 23 and the hopper 26 cause the moving shaft 36 and the shutter 30 (washer). (Movement is blocked by 44), and the leveling brush 27 is moved and retracted from above the seed fitting hole 31 into the seed fitting hole 31 (FIG. 13). Seeds fit.

Next, the sowing section 23 is placed in the horizontal position (9 of the clock).
16), the direction of movement is in the direction opposite to the arrow A, which is the frontward movement. Therefore, the discharge port 29 coincides with the seed fitting hole 31 to drop the seeds, and the seeds are passed one by one through the hose 55 to the sowing plate. It falls into the pot 2 through the drop opening 57 of the portion 56. In this case, since the pressing plate portion 59 having the pressing protrusions 58 is provided on the rear side of the seeding plate portion 56, the concave portion 60 is formed in the upper part of the soil 4 of the pot 2 and the seed is seeded in the concave portion 60. When the seeds fall, the seeding plate portion 56 is as close as possible to the upper surface of the pot 2, so that the seeding effect is prevented by preventing the seeds from scattering and improving the seeding accuracy. The moving axis 3
The relationship between 6 and the seeding section 23 will be described. In FIG. 11, since the moving shaft 36 is about to move in the direction opposite to the arrow A due to the elasticity of the spring 40, the engaging shaft 47 of the moving shaft 36 engages with the engaging member 49. It fits. The shutter 30 has a spring 43.
Although it is urged in the direction indicated by arrow A, it does not move because the regulating member 52 is in contact therewith. In FIG. 12, the seeding section 2
3 moves a little in the direction of arrow a, but the moving shaft 36 does not move and the spring 40 extends a little. In FIG. 13, since the seeding section 23 further moves in the direction of arrow A, the position of the shutter 30 in contact with the washer 44 does not change, but the hopper 26 moves together with the seeding section 23, so that the hopper does not move relative to the shutter 30. 26 moves in the direction of arrow a to move the seed fitting hole 3
When the seed 20 is fitted into the inside of 1 and the stopper 41 of the moving shaft 36 comes into contact with the front plate 37, the elasticity of the spring 40 does not urge the sowing section 23 in the direction of arrow a, and the sowing section 23 is provided by 40 and 41. The moving shaft 36 moves together with the seeding section 23, and the engaging shaft 47 at the rear end of the moving shaft 36 is engaged with the engaging member 49.
It is located further back (Fig. 14). At this time, the engagement shaft 47
When the engaging member 49 is removed further, the seeding section 23 and the moving shaft 36 both move circularly.

When the engaging member 49 is engaged with the engaging shaft 47, only the seeding portion 23 moves in the direction opposite to the arrow A while contracting the spring 40 as shown in FIG. 15, and eventually, as shown in FIG. The outlet 29 of the bottom plate 28 is aligned with the seed fitting hole 31,
The seed 20 falls into the hose 55 through the discharge port 29. Further, when the seeding section 23 moves in the direction opposite to the arrow A, the engagement leg 35 of the shutter 30 is disengaged from the washer 44.
5, so that the seeding part 23 can be used until it returns to FIG.
And the shutter 30 move together. Thus, the four drop openings 57 are formed in the seeding plate portion 56 of the seeding portion 23,
In the case of the seedling-growing mat 1 having individual pots 2, it is possible to inoculate all of the seedling-growing mat 1 by repeating 5 times, but when the seedling-growing mat 1 is not transferred for some reason, The sensing roller 91 descends to the front end of the support arm 90 of the engaging member 49, and the engaging member 49 retreats to a position where the engaging shaft 47 of the moving shaft 36 does not engage. There is no relative movement and no seeding. In addition, the manual switching device 92
It is also possible to forcibly rotate the support arm 90 to lower the sensing roller 91.

However, the seed 20 is obtained by coating vegetable seeds such as lettuce, and not only the size of the seed itself is different even in the same variety, but the size of the seed 20 also depends on the thickness of the coating. Is different. Therefore,
When sowing Chinese cabbage seeds after sowing the lettuce, the hopper 26 is removed from the sowing section 23, and the shutter 30 on the bottom plate 28 is removed.
And replace it with a shutter 30 having a seed fitting hole 31 that matches the size of another seed 20. Similarly, the nursery mat 1
, Several kinds of pots having different intervals are commercially available. Therefore, the seeding transfer piece 66 and the feed transfer piece 67 are reciprocally moved in opposite directions, and seeded from the feed transfer piece 67 at a certain point. The transfer piece 66 is taken over and the moving speed of the feed piece 67 for feeding is changed. That is, the seeding section 23 moves in a circle without stopping, sowing is performed by the descending stroke and the ascending stroke from the rear to the front, and the returning stroke is performed until the first seeding start position is reached. The speed at which the transfer piece 66 transfers from the takeover point T to the seeding point G is set to the seeding section 23.
The seedling raising mat 1 is transferred from the feed start point S to the transfer point T by the feed transfer piece 67 during the return stroke of the seeding section 23 in synchronism with the moving speed of the seedling section 23. Therefore, the seeding transfer piece 66 and the feed transfer piece 67 move the seedling-growing mat 1 by the distance between the pots 2 to be seeded at once by both (for example, 4 out of 20 pots 2), Among them, the movement of the seeding section 23 needs to make the diameters of the crank 25 and the sowing rotary disc 74 the same so as to be completely matched. However, the feeding transfer piece 67 moves the seedling-growing mat 1 at the transfer point T. After delivery, it is sufficient to reach the transfer point T at the same time as the returning sowing transfer piece 66. If the moving amount and moving speed of the sending piece 67 for feeding are changed, the seedling mat 1 with different intervals and number of pots 2 can be used. If so, you can sow.

For example, in FIG. 25, the feeding start point S
Is a feed start point of the feed transfer piece 67, a take-over point T is a take-over point where the tips of the feed transfer piece 67 and the sowing transfer piece 66 coincide, and a sowing point G is the sowing transfer piece 66 where the seedling mat 1 is placed. As a sowing point for sowing by advancing, the number of sowings by the sowing section 23 is arbitrarily set with respect to the total number of the pots 2 of the seedling raising mat 1, and the pot 2 of one sowing is divided by the set number of sowings. The number is calculated, and the interval from the first pot 2 to the last pot 2 at this time may be matched with the seeding interval C, and the length of the crank 25 is 40 mm, and 20
In the case of the seedling-growing mat 1 having the pots 2 with an interval of 25 mm, when attempting to sow four pots 2, the number of sowing times is 5, the sowing interval C is 100 mm, and the synchronous sowing interval A is 40 mm. , The feed interval B is 60 mm,
In the case of the above-mentioned seedling raising mat 1 having 18 pots with a gap of 25 mm, when trying to sow 3 pots 2,
The number of times of sowing was 6, the sowing interval C was 75 mm, and the synchronous sowing interval A was 40 mm, so the feeding interval B was 35 mm.
Becomes

When the intervals are different even with the same number of two pots, it is possible to cope with them by changing the feeding interval B without changing the synchronous plating interval A. For example, crank 25
With a length of 40 mm and 20 pots with a spacing of 25 mm
In the case of the above seedling raising mat 1 having 4 seeds, when trying to sow into 4 pots 2, the number of sowing times is 5, and the sowing interval C is
Is 100 mm, and the synchronous sowing interval A is 40 mm, so the feed interval B is 60 mm, but with 20 pieces, the interval is 3
In the case of the seedling raising mat 1 having 0 mm pots 2, when trying to sow four pots 2, the number of sowing does not change at 5 times, but the sowing interval C is 120 mm, and the synchronous sowing interval A is 40 mm. Therefore, the feed interval B may be set to 80 mm, and the position of the transfer point T does not change. Therefore, the feed start point S is moved to the rear side by 20 mm. At this time, the stop switch 76 and the start switch 78 are also changed corresponding to the change of the feed start point S. In the above description, it is explained that the length of the synchronous sowing interval A is not changed, but this is a principle, and the length of the synchronous sowing interval A is originally the crank 25.
Of the pressing protrusion 58 of the pressing plate portion 59.
It is set by the movement arc locus of No. 2, and may be changed depending on the size of the opening of the pot 2, the pressing depth, and the like. In this case, the length of the crank 25 is 40 mm and 2
In the case of 0 seedlings and the seedling-growing mat 1 having the pots 2 having an interval of 25 mm, when seeding 4 pots 2, the number of seeding is 5, the seeding interval C is 100 mm, and the synchronous sowing interval A is Since it is 40 mm, the feed interval B is 60 mm
However, when there is no change in the sowing interval C, which is the interval between the pots 2 to be sowed at one time, and when only the length of the crank 25 is changed to 50 mm, the sowing interval C is 100 mm, and the synchronous sowing interval A Is 50 mm, the feed interval B is 50 mm
All you have to do is Anything that can be transferred by the transfer device 5, such as a pot sheet for growing seedlings for rice transplanters and a vegetable seedling sheet having the same shape as the pot sheet but different in size, can be seeded on anything that can be transferred by the transfer device 5. ..

[0022]

[Effect] The present invention has a horizontal plate-like bottom plate 2 having a discharge port 29.
8 and a seed fitting hole 3 that relatively slides on the upper surface of the bottom plate 28.
The shutter 30 having the number 1 and the hopper 26 provided on the shutter 30 constitute the seeding section 23, and the seeding section 23 is configured to move circularly, and vertically below and below the seeding section 23 in a synchronized manner. In a sowing seedling mat 1 in which a large number of pots 2 are arranged side by side, below the sowing section 23, a sowing transfer piece 6 that reciprocates at the same speed as the sowing section 23.
6 and a transfer mechanism 65 including a transfer transfer piece 67 that reciprocates in the opposite direction to the transfer transfer piece 66, a seeding transfer piece 66 and a transfer transfer piece 6 are provided.
By simply changing the moving speed and moving distance of No. 7, any seedling raising mat 1, pot sheet or the like can be seed-seeded.

Since the projecting pieces 85 are fixed to the tips of the transfer pieces 66 and 67 and the through holes 86 are formed in the projecting pieces 85, the seeding transfer piece 66 and the feeding piece 66 are provided. The transfer piece 67 reliably engages with the inner wall without falling into the pot 2, and thus transfers reliably.
