  An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a seedling container called a pot sheet or a cell tray, which is called a person skilled in the art, and a large number of pots 2 are connected vertically and horizontally by a synthetic resin or a corrosive water-soluble paper material. Formed. The pot 2 of an Example is arranged in parallel 8 or 10 in the left-right direction, 16 or 20 is arranged in the front-back direction (transfer direction), and a total of 128 or 200 is arranged in parallel. The pot 2 is formed in a circular or square shape in plan view so as to become narrower toward the bottom, and a through hole 4 is formed on the bottom surface thereof.

Reference numeral 6 denotes a seed supply device for seeding the seedling container 1 and is provided at a position above the transfer table 7 for horizontally transferring the storage box 3 fitted with the seedling container 1. A transfer roller 8 that transfers the storage box 3 fitted with the seedling container 1 at a constant speed is arranged in the transfer table 7 in parallel in the transfer direction.
A seed supply hopper 9 is provided on the front upper portion in the transfer direction of the seedling container 1 of the seed supply device 6. Inverted octave-shaped guide plates 10 and 11 are provided at the lower part of the seed supply hopper 9, and a shutter / seed receiving plate 12 is attached to one guide plate 10 so as to be movable and the other guide plate 11 has the shutter function. A feed amount adjusting plate 15 for adjusting the size of the supply port 14 between the seed receiving plate 12 and the seed receiving plate 12 is provided.

In the vicinity of the lower end portion of the guide plate 10, the outer peripheral surface of the horizontal shaft feeding roll 18 is brought close to the guide plate 10. A fitting recess 19 is formed on the outer circumferential surface of the horizontal axis feeding roll 18 at predetermined intervals in the circumferential direction and the roll axis direction (bus line direction). A slit 20 is formed on the outer peripheral surface of the horizontal axis feeding roll 18 over the entire circumference in the circumferential direction of the horizontal axis feeding roll 18 so as to vertically divide the left and right intermediate positions of the respective fitting recesses 19.
The cross-sectional shape of the slit 20 is formed in a U-shaped groove shape with the upper side open. In this case, it is preferable that the boundary portion between the upper portion of the slit 20 and the outer peripheral surface of the horizontal axis feeding roll 18 is so-called chamfered and formed on the inclined surface 21 because the fitting of the seed S is good. In addition, the outer peripheral surface of the horizontal axis feeding roll 18 has a low fitting recess 19 in the roll axial direction (bus line direction), and a high gap between the fitting recess 19 and the fitting recess 19 results in good seed S fitting. It is suitable (FIG. 3).

In this case, the seed may be not only a normal seed but also a so-called coated seed in which the outer periphery of a seed having an irregular shape is coated in a spherical shape.
The depth of the slit 20 is formed to be the same as or slightly deeper than the fitting recess 19, and the scraper 22 is fitted into each slit 20. The scraping body 22 is formed by inserting a plate member thinner than the width of the slit 20 into the mounting shaft 23 and interposing the collar 24 loosely between the scraping bodies 22 so that each scraping body 22 extends in the axial direction of the mounting shaft 23. It moves so that it fits into each slit 20. The left and right sides of the attachment shaft 23 are attached to the arm 25, and the arm 25 is attached to the roll rotation shaft 26 of the horizontal axis feeding roll 18 by mounting.

  At the upper surface position on the rotation descending side of the horizontal axis feeding roll 18, the rotational centering is such that the axial center direction is parallel to the axial direction of the roll rotating shaft 26 of the horizontal axis feeding roll 18 and rotates in the same direction on the contact surface. A brush 27 is provided to sweep back excess seed that rotates together with the horizontal axis feeding roll 18 without being fitted into the fitting recess 19. The rotation leveling brush 27 is pivotally attached to a movement adjusting plate (not shown) that is movably provided on the side plate 30 of the seed supply device 6 at both left and right ends of the central shaft 28, and the movement adjusting plate is attached to the side plate 30. Attached movably with bolts (not shown).

  A derivative 33 for guiding the seed fitted in the fitting recess 19 from the upper position to the lower position is provided on the side surface of the horizontal axis feeding roll 18 on the rotation lowering side of the rotating leveling brush 27. The derivative 33 covers the outer surface of an elastic member 34 such as urethane with a resinous sheet (not shown), and the sheet 33 is brought into close contact with the side surface of the horizontal shaft feeding roll 18 to be in sliding contact.

  Thus, the fitting recess 19 is formed in a size (volume) in which only one seed is fitted, and the distance and the number in the left-right direction are matched with the number of strips of the pot 2 of the seedling raising container 1. Are formed at the same pitch in the circumferential direction in accordance with the pitch of the above, but the fitting recesses 19 having different numbers and intervals and pitches are formed on the same horizontal axis feeding roll 18, and the pot 2 of the seedling container 1 is formed. The horizontal axis feeding roll 18 having the combined fitting recess 19 is attached to and detached from the horizontal axis feeding roll 18 for selective use.

  The left and right side plates 30 of the seed supply device 6 are formed with attachment / detachment grooves 40 through which the roll rotation shaft 26 of the horizontal axis supply roll 18 passes. One end of the attaching / detaching groove 40 is formed in the groove bottom 41, and the groove bottom 41 is originally formed at a position where the roll rotation shaft 26 of the horizontal axis feeding roll 18 is located at the time of the sowing operation, and the other end of the attaching / detaching groove 40 is The mounting opening 42 is formed at the front edge of the side plate 30.

  The horizontal axis feeding roll 18 is inserted into the attaching / detaching groove 40 obliquely from the mounting opening 42 in the radial direction with respect to the axial direction of the roll rotating shaft 26 and the inside of the attaching / detaching groove 40 as it is. It is moved and mounted, and on the contrary, it is moved and removed in the detachable groove 40 for replacement.

  In this case, when the roll unit Y is configured with the scraping body 22 fitted to the slit 20 in the horizontal axis feeding roll 18 and is detachable in units of the roll unit Y, the horizontal axis feeding roll 18 is further layered. Facilitates exchange.

  The roll rotating shaft 26 positioned at the groove bottom 41 of the attaching / detaching groove 40 is supported by a pair of front and rear lower bearing rollers 45 provided on the side plate 30, and upper bearing rollers 46 are disposed on the upper surfaces of the left and right ends of the roll rotating shaft 26. Are brought into contact with each other. The upper bearing roller 46 is attached to the tip of the arm 47, and the base of the arm 47 is attached to the side plate 30 by a shaft 48 so as to be rotatable. Reference numeral 49 denotes a spring that urges the upper bearing roller 46 to retract from the roll rotation shaft 26, and reference numeral 50 denotes a fixing bolt. The fixing bolt 50 is screwed into a screw hole (nut) of the side plate 30 and Fix the rotation.

  Therefore, since the horizontal axis supply roll 18 supports the roll rotation shaft 26 of the horizontal axis supply roll 18 by the lower bearing roller 45 and the upper bearing roller 46, when the upper bearing roller 46 is removed, the roll rotation axis 26 is It can be removed from the side plate 30 through the attaching / detaching groove 40, and the horizontal axis feeding roll 18 can be easily replaced.

  The left and right ends of the roll rotating shaft 26 and the lower bearing roller 45 and the upper bearing roller 46 are not shown, but if they are formed as stepped rollers, the roll rotating shaft 26 is prevented from moving in the axial direction, sowing. The accuracy is improved, which is preferable.

Accordingly, a driven gear 51 is provided on the roll rotating shaft 26, and a chain 52 is hung around the driven gear 51. The chain 52 is wound around an output gear 54 of a motor 53 provided on the rear side of the horizontal shaft feeding roll 18.
In this case, the chain 52 is provided with an intermediate gear 55 on the side plate 30 so as to mesh with the outer periphery of the driven gear 51 on the side opposite to the attaching / detaching groove 40.

  That is, the lower intermediate gear 55A is provided at a predetermined position on the lower rear side of the driven gear 51, and the upper intermediate gear 55B is provided at a predetermined position on the oblique upper side of the driven gear 51. The intermediate gear 55B is located between the lower intermediate gear 55A and the upper intermediate gear 55B. The chain 52 is meshed with the driven gear 51.

  The intermediate gear 55C is an intermediate gear provided between the lower intermediate gear 55A and the output gear 54. Further, in the embodiment, the upper intermediate gear 55B is configured as a tension gear and is movably attached to the side plate 30 to adjust the tension of the chain 52.

Accordingly, the chain 52 between the lower intermediate gear 55A and the upper intermediate gear 55B is wound around the outer periphery of the driven gear 51 on the opposite side of the attaching / detaching groove 40, so that the chain 52 is one after another. It can be removed as it is through the attaching / detaching groove 40 without removing the upper intermediate gear 55B as a tension gear.
Also when mounting, when the roll rotation shaft 26 passes through the detachable groove 40 and reaches the groove bottom 41 and is supported by the lower bearing roller 45, the lower intermediate gear 55A and the upper intermediate gear 55B. The chain 52 between them may be hung around.

  Thus, the same number of position detection through holes 56 as the pots 2 are formed on the side surface of the horizontal axis feeding roll 18 in a circular shape around the roll rotation shaft 26. The side plate 30 is provided with a roll position detection sensor 57 for detecting the presence or absence of the position detection through hole 56. The roll position detection sensor 57 is formed by, for example, a photo sensor that detects light and dark, and is configured to detect the presence or absence of the position detection through hole 56.

In the embodiment, a window 58 is provided in the side plate 30, and the roll position detection sensor 57 is configured to detect the position detection through hole 56 through the window 58.
On the other hand, a container sensor 60 for sensing the transfer of the seedling container 1 is provided at a predetermined position of the transfer table 7 or the seed supply device 6. When the container sensor 60 senses the seedling container 1, the motor 53 is energized. The rotation of the horizontal axis feeding roll 18 is started, and the rotation of the fitting recess 19 of the horizontal axis feeding roll 18 and the movement of the pot 2 of the seedling raising container 1 are synchronized, so that about 1 to 3 grains are placed in each pot 2. Point sowing.

  That is, the rotation of the motor 53 is stopped and the horizontal axis feeding roll 18 is made to stand by so that the fitting recess 19 of the horizontal axis feeding roll 18 is stopped at the seeding position by the roll position detection sensor 57. The feeding roll 18 is rotated by sensing the seedling container 1 by the container sensing body 60, and thereafter, the fitting recess 19 of the rotating horizontal axis feeding roll 18 and the pot 2 of the seedling container 1 are synchronized, and the pot 2 that is moving Can be sown.

  Although the container sensor 60 of the embodiment is formed by a contact type limit switch, a non-contact type switch may be used. Similarly, the position detection through hole 56 and the roll position detection sensor 57 are provided with a position detection through hole 56 in a driven gear 51 or a separately provided member that rotates in synchronization with the rotation of the horizontal shaft feeding roll 18. 56 may be detected by a roll position sensor 57.

(Operation of Example)
When seeds are put into the seed supply hopper 9 and the storage box 3 fitted with the seedling raising container 1 is supplied to the transfer stand 7, it is transferred by the transfer roll 8 and reaches below the seed supply device 6.
The seed in the seed supply hopper 9 flows down on the shutter / seed receiving plate 12 and accumulates between the shutter / seed receiving plate 12 and the outer peripheral surface of the horizontal feeding roll 18, and the rising horizontal shaft feeding roll 18 is fitted. Excess seed that is fitted in the mating recess 19, rises by the rotation of the horizontal shaft feeding roll 18, and is not fitted in the fitting recess 19 that rotates together with the horizontal shaft feeding roll 18 is returned by the rotating leveling brush 27. The seeds are leveled and guided by the derivative 33 to reach the bottom, and are sown in the pot 2 of the seedling raising container 1.

  In this case, the fitting concave portion 19 of the horizontal axis feeding roll 18 is formed in a size (volume) in which a predetermined number (one) of seeds is fitted, and the horizontal direction depends on the number of strips of the pot 2 of the seedling container 1. The horizontal axis feeding roll 18 has the same number of position detection through holes as the pot 2 on the side surface of the horizontal axis feeding roll 18. 56 is formed in a circular shape around the roll rotation shaft 26, and the side plate 30 is provided with a roll position detection sensor 57 for detecting the presence or absence of the position detection through hole 56. The position detection through hole 56 and the roll position detection sensor 57 are provided as follows. When the seed supply device 6 is energized, the position detection through hole 56 and the roll position detection sensor 57 are left as they are, and the position detection through hole 56 and the roll position detection sensor 57 are in agreement. Horizontal axis feeding roll up to 8 is rotated and stopped in a standby state in which the fitting recess 19 is located at the drop position R which is substantially the center of the pot 2 passing below (because the container sensor 60 described later has not detected the seedling container 1). The roll position sensor 57 has priority).

Therefore, the seeds are put into the seed supply hopper 9 and are idled until the seeds fall at the dropping position R, and are temporarily stopped.
That is, the seed in the drop fitting recess 19A at the drop position R falls, but the seed is fitted in the standby fitting recess 19B in front of it (FIG. 9).

  Next, when the storage box 3 fitted with the seedling container 1 supplied to the transfer table 7 reaches a predetermined position below the seed supply device 6, the container sensing body 60 detects the seedling container 1 and the horizontal axis feeding roll 18. The rotation is started, and the rotating speed of the horizontal axis feeding roll 18 and the moving speed of the pot 2 are synchronized, whereby the rotating horizontal axis feeding roll 18 is continuously seeded on the moving pot 2.

  In this case, the container sensing body 60 is arranged so that the seedling container 1 moves by a predetermined distance T while the standby fitting recess 19B in which the seed of the horizontal axis feeding roll 18 that is on standby is fitted reaches the drop position R. Is positioned at a predetermined position (FIG. 9).

  While the seedling container 1 is being sown, since the container sensor 60 is on, the signal of the roll position sensor 57 is ignored, but sowing of one seedling container 1 is completed. When the container sensing body 60 is separated from the seedling raising container 1 and turned off, the roll position sensing sensor 57 detects the next position detection through hole 56 before the next fitting recess 19 reaches the drop position R, and the horizontal axis The rotation of the feeding roll 18 is stopped, and the operation is repeated when the container sensing body 60 senses the next seedling container 1.

  That is, when seeding in the drop fitting recess 19A at the drop position R in the last row of pots 2 of the seedling container 1, the seedling container 1 is separated from the container sensing body 60, so that the standby fitting recess 19B is at the drop position. Before rotating to R, the roll position detection sensor 57 senses the position detection through hole 56, stops the rotation of the horizontal axis feeding roll 18, and puts it in a standby state.

  Therefore, the pitch of the pot 2 of the seedling raising container 1 and the pitch of the fitting concave part 19 of the horizontal axis feeding roll 18 must be completely matched, and the fitting concave part 19 having a pitch matching the pitch of the pot 2 of the seedling raising container 1 is required. The horizontal axis feeding roll 18 having the

  Therefore, the left and right side plates 30 of the seed supply device 6 are formed with a detachable groove 40 through which the roll rotation shaft 26 of the horizontal axis feeding roll 18 passes, and one side of the detachable groove 40 is formed as a groove bottom groove bottom 41 and the other. Each side is formed in a mounting opening 42 opened to the front edge of the side plate 30, and the groove bottom 41 of the attaching / detaching groove 40 is set to a position where the roll rotating shaft 26 of the horizontal axis feeding roll 18 is mounted, and below the left and right groove bottoms 41. Are provided with a pair of lower bearing rollers 45 in the front and rear, and an upper bearing roller 46 is brought into contact with the upper surface of the roll rotating shaft 26. Therefore, the roll rotating shaft 26 of the horizontal shaft feeding roll 18 is a pair of lower bearing rollers. 45 and the upper bearing roller 46 are supported and rotated, and the roll rotating shaft 26 can move in the attaching / detaching groove 40 only by retracting the upper bearing roller 46, and the horizontal shaft feeding roll 18 can be removed.

  Therefore, since the horizontal axis supply roll 18 supports the roll rotation shaft 26 of the horizontal axis supply roll 18 by the lower bearing roller 45 and the upper bearing roller 46, when the upper bearing roller 46 is removed, the roll rotation axis 26 is It can be removed from the side plate 30 through the attaching / detaching groove 40, and the horizontal axis feeding roll 18 can be easily replaced.

  In this case, the upper bearing roller 46 is attached to the tip of the arm 47, the base of the arm 47 is rotatably attached to the side plate 30 by the shaft 48, and the upper bearing roller 46 is retracted from the roll rotation shaft 26 by the spring 49. When the fixing bolt 50 that fixes the arm 47 is removed, the upper bearing roller 46 is retracted from the roll rotating shaft 26, and the roll rotating shaft 26 can move in the detachable groove 40. Thus, the horizontal axis feeding roll 18 can be removed.

  Thus, an endless chain 52 is wound between the driven gear 51 of the roll rotating shaft 26 of the horizontal shaft feed roll 18 and the output gear 54 of the motor 53, but the outer peripheral side of the chain 52 is connected to the detachable groove 40. Since it is hung around a part of the outer periphery of the driven gear 51 on the opposite side and does not come into contact with the outer periphery of the driven gear 51 on the moving direction side of the attaching / detaching groove 40, the driven gear is removed when the horizontal shaft feeding roll 18 is removed. 51 simply leaves the chain 52 and can be removed as it is.

  That is, the intermediate gear 55 is attached to the side plate 30 between the driven gear 51 and the output gear 54 of the motor 53 so that the chain 52 meshes with the outer periphery of the driven gear 51 on the side opposite to the attaching / detaching groove 40.

  In the embodiment, a lower intermediate gear 55A is provided at a predetermined position on the lower rear side of the driven gear 51, and an upper intermediate gear 55B is provided at a predetermined position on the oblique upper side of the driven gear 51. The lower intermediate gear 55A and the upper intermediate gear 55B are provided. Since the intermediate chain 52 is meshed with the driven gear 51, the chain 52 between the lower intermediate gear 55A and the upper intermediate gear 55B is pressed against the rear side surface of the driven gear 51 to transmit the rotation.

  Accordingly, the outer peripheral side of the chain 52 between the lower intermediate gear 55A and the upper intermediate gear 55B is wound around so as to mesh with the outer periphery of the driven gear 51 on the side opposite to the attaching / detaching groove 40. Without being removed from the intermediate gear 55 or the upper intermediate gear 55B, which is a tension gear, can be removed as it is through the attaching / detaching groove 40.

  Also when mounting, when the roll rotation shaft 26 passes through the detachable groove 40 and reaches the groove bottom 41 and is supported by the lower bearing roller 45, the lower intermediate gear 55A and the upper intermediate gear 55B. The chain 52 between them may be hung around.

  In this way, the horizontal axis feeding roll 18 having the fitting recesses 19 having a pitch matched to the pitch of the pot 2 of the seedling raising container 1 can be easily attached and detached and selectively used so that the horizontal axis feeding roll during continuous rotation can be selected. 18 and the moving speed of the pot 2 are synchronized, so that the continuous seeding operation is realized.

  Thus, the scraping body 22 is fitted to the slit 20 of the horizontal axis feeding roll 18, but the arm 25 is connected to the slit 20 in the state where each scraping body 22 is fitted to each slit 20.
