The transfer table 7 is provided with transfer rollers 8 (FIG. 16) for transferring the storage box 3 fitted with the seedling raising container 1 at a constant speed. A seed supply hopper 9 is provided on the front upper portion of the seed supply device 6 in the transfer direction of the seedling raising container 1. In the lower part of the seed supply hopper 9, the sloping slugs 10 and 11 are provided.
The shutter / seed receiving plate 13 is attached to the
A feeding amount adjusting plate 14 for adjusting the size of the supply port 12 between the shutter plate 11 and the shutter / seed receiving plate 13 is provided on the other drifting plate 11.

[0008] In the vicinity of the lower end portion of the slug 10, it is brought close to the outer peripheral surface of the horizontal shaft feeding roll 15. Horizontal axis feeding roll 15
Are formed at predetermined intervals in the circumferential direction and in the roll axis direction. Further, a slit 18 is formed on the outer peripheral surface of the horizontal axis feeding roll 15 so as to vertically divide the left and right intermediate positions of the fitting recesses 16.
5 is formed over the entire circumference in the circumferential direction. The cross-sectional shape of the slit 18 is a U-shaped groove whose upper side is open, and a boundary between the upper part of the slit 18 and the outer peripheral surface of the horizontal axis feeding roll 15 is formed into an inclined surface 29 by so-called chamfering ( 10 and 11). The inclined surface 29 is formed into a concave groove shape from the left and right sides, but is formed to have a width such that the seeds are not fitted or clogged. The depth of the slit 18 is
And a little deeper, and each slit 18 has a scrape 1
9 is fitted. The scraping body 19 is illustrated in FIG.
It differs from the other embodiment diagrams in the arrangement interval and number,
It is not limited to this.

At the upper surface position on the rotation lowering side of the horizontal axle feeding roll 15, a rotation is made such that the axial direction is parallel to the axial direction of the rotating shaft 20 of the horizontal axle feeding roll 15 and rotates in the same direction on the contact surface. A leveling brush 21 is provided to sweep back excess seeds that do not fit into the fitting recesses 16 and rotate together with the horizontal shaft feeding roll 15. The rotating leveling brush 21 has a central axis 22.
The left and right end portions are axially attached to a movement adjusting plate 24 provided on a side plate 23 of the seed supply device 6, and the movement adjusting plate 24 is movably attached to the side plate 23 by bolts 25. 36 is a contact body for removing foreign matter including seeds, and 37 is a seed receiving box. On the side surface of the horizontal advancing roll 15 on the rotation lowering side of the rotating leveling brush 21, there is provided a derivative 26 for guiding the seeds fitted in the fitting recesses 16 from the upper position to the lower position so as not to be damaged. The derivative 26 covers a resin sheet 28 on the outer surface of an elastic member 27 such as urethane, and brings the sheet into close contact with the side surface of the horizontal axis feeding roll 15 to make sliding contact. Thus, the fitting recess 16 is formed in a size (volume) in which only one seed fits, and the interval and number in the left and right direction are adjusted to the number of the pots 2 of the seedling raising container 1. Are formed at the same pitch in the circumferential direction according to the pitch of the same horizontal shaft feeding roll 15
The unused fitting recess 16 is closed by the number-of-steps changing shield 17 described later, and the fitting recess 16 to be used is exposed. Therefore, the pot 2 of the seedling raising container 1 of the embodiment is
Since it is for 8-row and 10-row, the 8-row fitting recess 16a (N-row fitting recess 16a) and the 10-row fitting recess 16b (n-row fitting recess 16b) are formed accordingly. One of the eight-row fitting recess 16a and the ten-row fitting recess 16b is exposed by the strip changing shield 17, and the other is shielded.

In this case, the number-of-rows changing shield 17 is provided with the eight-row fitting recess 16a or the ten-row fitting recess 16b.
A window 38 for exposing one of the fitting recesses 16 to be used, and a shielding portion 39 for shielding the other unused fitting recess 16, and the window 38 and the shielding portion 3.
Several types having different positions from 9 are prepared and selected for use. In the embodiment, two types, one for eight and one for ten, are prepared. The relationship between the window 38 and the shield 39 is such that the window 38 is made as large as possible to expose not only the fitting recess 16 but also the outer peripheral surface in the width direction of the horizontal axis feeding roll 15. 39 is formed in a size as small as possible so that the unused recess 16 can be shielded. Since the number-of-rows changing shield 17 regulates the seeds from being fitted into the fitting recesses 16, the horizontal axis is extended from the shutter / seed receiving plate 13 below the rotating flat brush 21 or to the derivative 26. It is provided so as to be in close contact with the outer surface of the roll 15, is formed of a synthetic resin or a thin metal plate into an arc shape corresponding to the outer peripheral surface shape of the horizontal axle feeding roll 15, a mounting hole 40 is formed in a front side portion, and a rear side portion is formed. A mounting portion 41 is provided on the side,
The attachment hole 40 and the attachment portion 41 are detachably attached to the attachment portion 42 of the seed supply hopper 9, respectively.

In this case, the seed number changing shield 17 may be detached from the seed supply hopper 9 from the frame 43 of the seed supply device 6 and exchanged in this state. The combined number-of-rows changing shield 17 may be attached and prepared, and the seed supply hopper 9 may be selected and replaced for use. Thus, the shutter / seed receiving plate 13 is provided with the inclined portion 4 corresponding to the flocking plate 10.
4 and a substantially horizontal receiving plate portion 45 formed thereunder.
5 is brought into contact with the upper surface of the number-change shield 17. On the front side of the shutter / seed receiving plate 13, a seed take-out box 46 is provided.
Is provided. The seed take-out box 46 is attached to the front side of the seed supply hopper 9 to form an enclosed take-out space between the seed feed hopper 9 and the outer periphery of the horizontal shaft feed roll 15. The seeds are dropped into the seed take-out box 46 from the opening between the two, and the seeds in the seed supply hopper 9 are collected.
Thus, in the seedling raising container 1, the pots 2 intermittently move one row at a time, and the seeds are supplied below the horizontal advancing roll 15. Therefore, the transfer of the seedling raising container 1 and the horizontal roll 1
Synchronize the rotation of 5.

As an example, reference numeral 67 denotes a motor, and a chain 7 is provided between an output gear 68 and an intermediate gear 69 of the motor 67.
Multiply by zero. A pair of front and rear receiving rollers 71 are provided on the left and right side plates 23 of the seed supply device 6, and a pair of right and left moving shafts 72 in the front and rear direction are respectively mounted on the receiving rollers 71. Moving axis 72
, One end of a rod 73 is axially mounted, and the other end of the rod 73 is axially fixed to the intermediate gear 69 to convert the rotational movement of the intermediate gear 69 into a front-rear lateral movement. A pulley 75 is provided on the rotating shaft 74 of the intermediate gear 69, and the moving shaft 7 is attached to the pulley 75.
The other end of the rod 73 having one end attached to 2 is axially mounted. In addition, the pulley 75 and the central shaft 22 of the rotating leveling brush 21 are used.
The belt 77 is wound around the pulley 76 in a cross state. Reference numeral 78 denotes a guide roller which receives the moving shaft 72 and vertically guides it by the roller 71. Both ends of a pair of front and rear transfer shafts 80 are fixed to the left and right moving shafts 72, respectively. A pair of transfer projections 81 are attached to the transfer shaft 80 so as to be rotatable only by its own weight, and the transfer protrusions 81 can freely rotate upward but are restricted from rotating downward by stoppers 82 fixed to the transfer shaft 80. . In addition, the transfer projection 81 is inclined at the top surface of the distal end so that the transfer protrusion 81 can easily contact the inner surface of the pot 2 (FIG. 15). One transfer shaft 8 of the transfer shafts 80
A moving shaft 83 for synchronization is provided near zero. Synchronous moving shaft 8
Reference numeral 3 denotes a shaft mounted on the side plate 23 so as to be rotatable only, a base of an arm 84 is fixed to the moving shaft 83 for synchronization, and one end of a rod 85 is attached to a tip of the arm 84. To the shaft 80. Therefore, the transfer shaft 8
Due to the forward / backward movement of 0, the synchronization moving shaft 83 alternately repeats normal rotation and reverse rotation.

One end of the synchronization moving shaft 83 projects laterally from the side plate 23, and an intermediate arm 86 is fixed to the end of the synchronization moving shaft 83, and the base of the driving arm 87 is attached to the tip of the intermediate arm 86. Axle. The driving arm 87 has an engaging portion 88 at the tip. The center of a vertical disc 89 is fixed to the rotating shaft 20 of the horizontal shaft feeding roll 15, and an engaging pin 90 protruding laterally in parallel with the rotating shaft 20 is fixed to the disc 89 at a predetermined interval in the circumferential direction. And place them side by side. In the embodiment, ten pots 2 are used since the seedling raising container 1 in which ten pots 2 are juxtaposed in the front-rear direction is used. When the driving arm 87 moves in the horizontal direction, it engages with the engaging pin 90 and pushes forward, thereby rotating the disc 89 to rotate the horizontal axis feeding roll 1.
Rotate 5 A lower end of the driving arm 87 is brought into contact with a supporting roller 91, and the supporting roller 91 is connected to the clutch arm 9.
2, the base of the clutch arm 92 is fixed to a left-right sensing shaft 93, and the sensing shaft 93 is mounted on the side plate 23. The base of a flat plate-shaped sensing element 94 protruding forward is fixed to the sensing shaft 93 at a position corresponding to the position above the flat part 5 of the seedling raising container 1. Therefore, when the sensing element 94 senses the seedling raising container 1, the sensing shaft 93 is rotated to rotate the clutch arm 92 upward to support the driving arm 87 and engage the engaging pin 90, and , The clutch arm 92 rotates downward, the driving arm 87 does not engage with the engagement pin 90, and does not rotate the horizontal shaft feeding roll 15.

The transfer projection 81 is so constructed that it can be sown in the seedling raising container 1 of the pot 2 having a different pitch without changing the stroke. First, first,
When there are large and small pots 2, the length of the transfer projection 81 is relatively changed by a half of the difference between the sizes of the large pot 2L and the small pot 2S. That is, the stroke T is the amount by which the transfer projection 81 is moved by bringing the transfer protrusion 81 into contact with the inner wall of the pot 2, and thus is equal to the amount of movement of the inner wall of the large pot 2L (FIG. 1).
7). Next, this stroke T is the same even if the length of the transfer projection 81 is changed as shown in FIG. 17 except that the position of the stroke start point and the end point (the position of the transfer shaft 80) are different (one point from the solid line). Although the inner diameter of the small small pot 2S is smaller than the large pot 2L by H, the inner diameter of the large pot 2L and the small pot 2S is smaller than that of the large pot 2L. The centers coincide with each other and are shifted forward and backward by half of H, and if the length of the transfer projection 81 is shortened by this h, the transfer protrusion 81 will be located closer to the stroke end, and the small pot 2S The center can be made to coincide with the center of the large pot 2L.

Therefore, paying attention that the difference in pitch at the seeding position is half of the overall difference, and to make the centers of the large pot 2L and small pot 2S coincide with each other at the seeding position, The length may be changed, and in the case of the small pot 2S, the transfer projection 81 returns to the stroke start point, thereby absorbing the remaining half h. The stroke T may be adjusted to the pitch of the large pot 2L.
In the embodiment, the length is slightly increased in consideration of a manufacturing error (FIGS. 18 to 22). Next, as shown in FIG. 18, the positional relationship between the pair of front and rear transfer protrusions 81 and the horizontal shaft feed roll 15 is such that the rear transfer protrusion 81 and the horizontal shaft feed roll 15 are
At the stroke end pressed by 1, the horizontal axis feeding roll 15 is provided at a position above the point where the centers of the large pot 2L and the small pot 2S coincide with each other. Since there are several places where the center of the large pot 2L coincides with the center of the large pot 2L, there is no displacement at the point where the front and rear transfer projections 81 abut on the front side based on this distance. In FIG. 18, the horizontal axis feeding roll 15 is positioned slightly behind the coincidence point between the center of the small pot 2S and the center of the large pot 2L in consideration of the time difference until the seeds fall into the pot 2. Let me.

As described above, the length of the transfer protrusion 81 is relatively changed by a length corresponding to half of the size difference between the large and small pots 2, and a pair of front and rear transfer protrusions 81 and a horizontal member therebetween. Since the center of some of the pots 2 whose center is shifted from the center in the front and rear of the seed drop point of the shaft feeding roll 15 is coincident, these intervals are set as a reference and the seeding position and the transfer are synchronized. FIG. 19 illustrates an example in which the lengths of the connecting portions between the small pots 2S are different based on the above-described configuration. In this case, if the configuration is the same, synchronization can be achieved. FIG. 23 shows the transfer projection 8.
An example of a means for changing the length of the shaft 51 is shown. A pivoting member 50 is attached to the tip of a transfer projection 81 by a shaft 51 so as to be switchable between a long position and a short position. 52 and 53 are formed, and the through-hole 54 formed in the rotating member 50 is overlapped and fixed at the switching position by the stop shaft 55.

While the transfer roller 8 at the start end of the transfer table 7 is driven to rotate, the transfer roller 8 on the front side of the seed supply device 6 allows the roller 96 to loosely fit on the rotation shaft 95 of the drive rotation. The roller 96 rotates forward by friction, but reverses when a resistance is applied to the transfer of the seedling raising container 1. A freely rotating support roller 97 is provided below the seed supply device 6, and the drive-rotation transfer roller 8 is provided side by side from a predetermined position on the end side of the seed supply device 6.
Although not shown, the transfer table 7 may be provided with a floor soil supply device, a cover soil supply device, a rotating brush, or the like, to form a fully automatic sowing device.

[0018]

Next, the operation will be described. Since the present invention is configured as described above, the seeds are put into the seed supply hopper 9 and the storage box 3 fitted with the seedling growing container 1 is supplied to the transfer table 7, the seeds are transferred by the transfer rolls 8, and the lower part of the seed supply device 6 Leads to. The seeds in the seed supply hopper 9 flow down on the shutter / seed receiving plate 13 and the shutter / seed receiving plate 13 and the horizontal axis feeding roll 1
5, which accumulates between the outer peripheral surface (more precisely, the number-of-steps changing shield 17), fits into the fitting recess 16 of the rising horizontal-axis feeding roll 15, rises by rotation of the horizontal-axis feeding roll 15, and moves upward. Excess seeds that are not fitted in the fitting recesses 16 that co-rotate with the shaft feeding roll 15 are returned and leveled by the rotating leveling brush 21, guided downward by the derivative 26, and moved down to the pot of the seedling raising container 1. 2 seeded. Thus, the fitting recess 16
Are formed in the axial direction of the horizontal axis feeding roll 15 in accordance with the number of the pots 2 of the seedling growing container 1 and in the rotation direction of the horizontal axis feeding roll 15 in accordance with the pitch of the pot 2.
A horizontal axis feed roll 15 having a fitting recess 16 having a different number of threads and a different pitch is used. Since the fitting recess 16 to be used is exposed by the window 38 of the fitting 17, the fitting recess 1 exposed by the window 38 is formed.
6 are sown, and the horizontal axis feeding roll 15 is sown.
Are seeded (point-sown) one by one into each pot 2 of the seedling raising container 1 having a different number of rows and a different pitch.

In this case, the number-of-steps changing shield 17 has the shielding portion 39 formed with a minimum area capable of shielding the unused fitting concave portion 16, and the window portion 38 allows the periphery of the fitting concave portion 16 to be used. Because the seeds are exposed as much as possible,
By contacting the outer peripheral surface of the roller 5 and rotating or vibrating, the roller 5 is positioned around the horizontal axle feeding roll 15 in a so-called dancing manner and is securely fitted. In this regard, if the width of the window 38 is reduced in accordance with the width of the fitting recess 16 to be used, the fitting recess 1
The number of seeds facing 6 is small, the probability of fitting is reduced, and sowing accuracy is reduced. Also, the horizontal axis feeding roll 15
The slit 18 is formed over the entire circumference in the circumferential direction of the horizontal axis feeding roll 15 by vertically dividing the left and right intermediate position of the fitting recess 16 so as to connect the fitting recesses 16. Since the boundary between the outer peripheral surface of the horizontal axis feeding roll 15 on the upper side of 18 and the inclined surface 29 is chamfered and formed on the inclined surface 29, the seed is guided to the fitting recess 16 by the slit 18 widened by the inclined surface 29. Thus, the seeding accuracy is improved by securely fitting the fitting recess 16. In addition, when the number-changeable shield 17 having the window 38 opened greatly is used, the fitting rate is further improved by a synergistic effect.

The number-of-rows changing shield 17 is provided on the horizontal axis feeding roll 1.
The seed supply hopper 9 fitted to the fitting recess 16 of FIG.
Since it is detachably attached to the attachment portion 42, the seeds can be seeded into the seedling raising containers 1 having different numbers of rows only by changing and selecting and using. In this case, if the entire seed supply hopper 9 is detached, the replacement operation is easy, and the seed supply hopper 9 equipped with the number-of-rows changing shield 17 is attached, so that the positioning is easy and the attachment accuracy is high. , Sowing accuracy is also improved. Thus, the number-of-rows changing shield 17 has its front end fixed to the back side (front side) of the shutter / seed receiving plate 13,
Since the rear end is located on the rotation lowering side with respect to the rotating leveling brush 21, the seeds are fitted only into the fitting recesses 16 exposed from the respective windows of the row number changing shield 17, and the row number changing shield 17
It does not fit in the fitting concave portion 16 shielded by. Also,
Since the number-of-steps changing shield 17 is formed of a synthetic resin or a thin metal plate and is thin, it does not adversely affect the existence of the shutter / seed receiving plate 13 and the rotating flat brush 21 at all.

A shutter / seed receiving plate 13 is provided on the lower surface side of the slug 10 and the shutter / seed receiving plate 13 is provided.
The seed take-out box 46 is provided below the container, so that during the sowing operation, the shutter-seed receiving plate 13 closes the gap between the flow-breaking plate 10 and the horizontal-axis feeding roll 15, and when the operation is completed,
When the shutter / seed receiving plate 13 is moved upward and retracted to open the opening, the remaining seeds fall into the seed take-out box 46, and the seed take-out box 46 together with the seed supply hopper 9 is removed and collected. Thus, in the seedling raising container 1, the pots 2 intermittently move one row at a time, and the seeds are supplied below the horizontal advancing roll 15. For this reason, the transfer of the seedling raising container 1 and the rotation of the horizontal axis feeding roll 15 are synchronized. In this case, the motor 67
Rotation of the output gear 68 → the chain 70 → the intermediate gear 69
(Rotary shaft 74, pulley 88) → rod 73 → moving shaft 72
And the transfer shaft 80 is moved
Moves back and forth, and the transfer projection 81 of the transfer shaft 80 engages with the inner surface of the pot 2 of the seedling raising container 1 and moves forward by one row.

On the other hand, the forward / backward movement of the transfer shaft 80 causes the synchronization movement shaft 83 to alternately repeat forward and reverse rotations. The rotation of the synchronization movement shaft 83 causes the intermediate arm 86 to rotate. Move the driving arm 87 at the tip back and forth,
Further, since the sensing element 94 is rotated upward by the seedling raising container 1, the clutch arm 92 is rotated upward, and the driving roller 87 is supported by the support roller 91, the engaging portion 88 at the tip of the driving arm 87 is circular. It engages with the engaging pin 90 of the plate 89 and pushes forward, thereby rotating the disk 89 to rotate the horizontal axle feeding roll 15 and dropping a row of seeds. Accordingly, the transfer of the seedling raising container 1 by the transfer protrusion 81 and the rotation of the horizontal axis feeding roll 15 are synchronized, and when the seedling raising container 1 does not exist, the driving arm 8 is supported by the support roller 91.
Since the seed 7 is not supported, the seeds do not drop, and synchronization is also achieved in this respect. With a simple configuration, synchronization can be ensured and the seedling raising container 1 can be sensed, thereby reducing the cost. Thus, the transfer protrusion 81
Is provided with a rotating member 50 which can be switched between a long position and a short position on the distal end side, and the transfer projection 81 moves between a short position and a long position which are shorter by h which is half the size difference H of the large and small pots 2. When the large pot 2L is long and the small pot 2S is short, the transfer protrusions 81 can be seeded into the pots 2 having different pitches without changing the stroke.

That is, since it is shorter by the size difference h,
The stroke end point of the transfer projection 81 is located on the near side, and the small pot 2S is positioned below the horizontal axis feeding roll 15 with respect to the seeding position. Next, when the transfer projection 81 returns to the stroke start point, the return returns to a position considerably short of the pitch of the small pot 2S.
There is no effect on the transfer of the seedling raising container 1, and the returned amount absorbs the remaining shift of h. Therefore, since the stroke of the transfer protrusion 81 is not changed, adjustment of the drive mechanism of the horizontal-axis feeding roll 15 and the transfer protrusion 81 is unnecessary, and the seed can be easily seeded into the pots 2 having different pitches. Further, even in the seedling raising container 1 having the pots 2 having different pitches, when the seedling containers 1 are arranged side by side in front and rear, there is a pot 2 whose center coincides at a constant interval. When the pair of front and rear transfer projections 81 and the horizontal axis feeding roll 15 are arranged, even if the pots 2 having different pitches are transferred, the transfer projections 81 engage with the pot 2 and are located below the horizontal axis feeding roll 15. Coincides with the center of pot 2. As described above, not only can the seedling raising container 1 having a different number of lines be sowed by the number-of-rows changing shield 17, but also the seeding can be accurately sowed even when the pitch of the pot 2 is different due to the change of the number of lines. And improve workability.

[0024]

According to the present invention, fitting recesses 16 are formed at predetermined intervals in the circumferential direction and axial direction above the transfer table 7 for transferring the seedling growing container 1 having a large number of pots 2 vertically and horizontally. In the seeding apparatus provided with the horizontal axis feeding roll 15, the transfer projections 81 on the left and right sides of the horizontal axis feeding roll 15 engage with the pot 2 when moving forward and do not engage when moving backward.
Are provided so as to reciprocate back and forth, and the transfer projection 81 and the horizontal axis feeding roll 15 are intermittently synchronously driven.
1 is configured to be freely changeable in length, and for large and small pots 2,
Since the transfer projection 81 used for the small pot 2S is relatively short with respect to the large pot 2L by half h of the difference H between the two, the seeding device for a pot-type seedling raising container is used. The seedling containers 1 having different pitches of the pots 2 can be sowed easily without exchanging the horizontal advancing roll 15 and the transfer protrusions 81, adjusting the position change, and improving the workability. In the present invention, the pair of front and rear transfer protrusions 81 and the horizontal axis feeding roll 15 provided in the middle of the transfer protrusions 81 are arranged such that the front and rear of the two seedling raising containers 1 having the pots 2 having different pitches are arranged in front and rear. When aligned side by side,
Since the seeding device for a pot-type seedling raising container is arranged based on the interval between the pots 2 whose centers coincide with each other, the device operates accurately and does not reduce the seeding accuracy of the seedling container 1 with a different pitch of the pots 2. The present invention relates to the horizontal axle feeding roll 1
5, the fitting recess 16a for the N-section and the fitting recess 16b for the n-section correspond to the pot 2 of the seedling raising container 1.
Are formed at equal intervals, and a thin sheet-shaped strip-number changing shield 17 having a window portion 38 for exposing the fitting concave portion 16 and a shielding portion 39 for shielding the outer peripheral surface of the horizontal-axis feeding roll 15 is provided.
The number-of-strips changing shield 17 is provided with different positions of the window 38 and the shield 39, and one of the N-section fitting recess 16a and the n-section fitting recess 16b is provided. And use it selectively so as to shield one of the other,
The window portion 38 is as large as possible, and the shielding portion 39 is a pot-type seedling raising container sowing apparatus formed as small as possible. Therefore, only the seedling raising container 1 having the pots 2 having different pitches is used. In addition, even when the pitch of the pot 2 is different due to the change in the number of strips, the seeding can be accurately performed, and the seeding can be performed even when both the number of strips and the pitch are different, thereby improving versatility and improving workability. .
