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 for seeding 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, but by changing the length of the rod 73 and the attachment portion to the feed rotary disc 75, the pot sheet 1 by the feed transfer piece 67 is changed. Adjust the feeding speed of. That is, since the pot sheet 1 is commercially available in several types with different intervals between the pots 2, the seeding transfer piece 66 and the feed transfer piece 67 are reciprocally moved in opposite directions, and are fed at a certain point. The transfer piece 67 for transfer is taken over by the transfer piece 66 for seeding, and the moving speed of the transfer piece 67 for feed up to this transfer is changed.

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 take-over point where the tip end coincides with 6, and G is a sowing point at which the sowing transfer piece 66 advances and sows the pot sheet 1. Then, the synchronous sowing interval A is determined by the length of the crank 25, but the seeding portion is set with respect to the total number of the pots 2 of the pot sheet 1 due to the relative relationship between the drop opening 57 and the number of the pots 2 in the transfer direction. 23, the number of seeds is arbitrarily set, and the total number of pots 2 is divided by the set number of seeds to obtain the number of pots 2 to be seeded once. At this time, from the first pot 2 to the last pot 2, Interval and seeding interval C
Match with. For example, the length of the crank 25 is 40m
m, in the case of the pot sheet 1 in which 20 pots 2 in the transfer direction are arranged side by side at an interval of 25 mm, when sowing 4 pots, there is no surplus for 20 pots 2, and the number of sowings is 5,
The seeding interval C is an interval of 25 mm × 4 pots = 100 mm
As described above, since the synchronous sowing interval A is 40 mm, the feeding interval B is from the sowing interval C to the synchronous sowing interval A.
Minus 60 mm. Also, similarly, pot 2
When the number is 18 and the interval is 25 mm, it is preferable to sow in three pots 2, the number of times of sowing is 6, the sowing interval C is 75 mm, and the synchronous sowing interval A is 40 mm. The feed interval B is 35 mm, and the feed interval B and the feed start point S of the feed transfer piece 67 can be changed by changing the length of the rod 73.

Incidentally, the seeding plate portion 56 and the pressing plate portion 5
9 are prepared by exchanging several types of drop ports 57 and pressing protrusions 58 having different numbers and intervals (for example, when 20 pots 20 are used, four dropping ports 57 and pressing protrusions 58 are seeded). Using the plate portion 56 and the pressing plate portion 59, 1

[0014]

[Operation] Next, the operation will be described. Since the seed feeding device 22 is provided on the frame 14 of the fixed transfer table 5 through the vertical movement device 21 so as to be adjustable in height, the cam plate 89 is rotated by loosening the nut 100 and then rotating the cam plate 89 by the handle 97.
Will rotate about the horizontal axis 87, and since the horizontal axis 87 is decentered from the center of the circular cam plate 89, it will move up and down with respect to the frame 14 by the rotation of the cam plate 89. When the horizontal axis 87 moves up and down, the vertical up-down vertical axis 53 moves up and down via the mounting plate 84 to which the horizontal axis 87 is attached, and the nut 83 on the upper part of the vertical up-down vertical axis 53 moves down when the vertical up-down vertical axis 53 moves. When the seed feeding device 22 is lowered and the vertical vertical axis 53 moves upward, the spring 98 moves the seed feeding device 22 upward, and the nut 100 is tightened to fix the cam plate 89 to the mounting plate 84. That is, the seed feeding device 22 is supported by the spring 98 of the vertical movement device 21 so as not to descend, and the seed feeding device 22 is not moved upward by a predetermined height by the nut 83. In addition, the pair of left and right cam plates 89 has a horizontal axis 87.
Since one of the handles 97 is rotated, the left and right cam plates 89 act. When the positions of the left and right cam plates 89 fixed to the horizontal shaft 87 are displaced, the left and right nuts 8 are
The seed feeder 22 is made horizontal by 3 (note that the vertical upper and lower vertical axes 53 are a pair of left and right, and the seed feeder 2 is
Provide several sets before and after 2.) Then, the seed supply device 22 for the fixed transfer table 5 corresponding to the height of the pot sheet 1
Adjust the height of. When the pot sheet 1 is supplied to the fixed transfer table 5 in this state, the soil is supplied by the floor soil supply device 8 to reach below the scraper 9, and the scraper 9 is supplied to the soil 4 Among them, the floor soil 4 is left above the pots 2 by the notch portion 12, and the floor soil 4 on the upper surface 14 of the pot sheet 1 between the pots 2 is removed by the scraping portion 13. Therefore, the crushing roller 15 can compress the floor soil 4 above the pot 2 as much as possible to the upper surface position of the pot sheet 1, and thus reliably crush the floor soil 4 in the pot 2. The pot sheet 1 that has passed below the compression roller 15 is pushed into the pot 2 by the elastic leveling brush 16 into the pot soil 4 on the upper surface 14 of the pot sheet 1 between the pots 2 and 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 pot sheet 1 comes into contact with the stop switch 76, the rotation of the transfer roller 77 is stopped, and the pot sheet 1 waits at this point (feed start point S). On the other hand, the rod 73, which is moved backward by the rotation of the feed rotary disc 75, moves the feed transfer piece 67 backward, and the feed transfer piece 67 is on standby, and the inner wall of the first pot 2 of the pot sheet 1. To engage the feed start point S to start the forward movement (when the leading end of the pot sheet 1 comes into contact with the start switch 78, the transfer roller 77 is rotated again). Then, when the feeding transfer piece 67 starts to move forward, the sowing transfer piece 66 starts to move backward, and the tip of the sowing transfer piece 66 and the tip of the sending transfer piece 67 coincide with each other at the takeover point T. The transfer piece 66 continues to advance the pot sheet 1 from the transfer point T. The crank 25 for moving the seeding section 23 and the seeding rotary disc 7 of the seeding transfer piece 66.
Since the diameters of 4 are the same, the transfer speed of the sowing transfer piece 66 and the transfer speed of the sowing section 23 are the same, and the upper surface of the soil floor 4 of each pot 2 of the pot sheet 1 is gradually moved by circular movement. It is pressed by the pressing protrusions 58 of the pressing plate portion 59 that descends. On the other hand, in the seed feeding device 22, since the seeding section 23 is repeatedly moved circularly via the cranks 25, 25, the seeding section 2
The seed 20 can be sown by dropping the seed 20 while moving while keeping the dropping port 57 formed in the sowing plate portion 56 at the lowermost end of 3 aligned with the pot 2. In this case, the height adjustment of the seed supply device 22 is performed by adjusting the drop opening 57 of the sowing plate portion 56 so as to match the height of the pot 2. By changing the height, it is possible to change and adjust the depth at which the pressing protrusions 58 of the pressing plate portion 59 press the floor soil 4 of each pot 2 (note that the pressing protrusions 58 are
If the pressing depth of is shallow, the drop port 57 approaches the pot 2, and if the pressing depth is deep, the drop port 57 moves away from the pot 2, but this is within the allowable range and the seeding accuracy is not affected).

When the front and rear cranks 25 rotate, the whole seeding section 23 moves circularly (counterclockwise in the figure), and the engaging member 49 engages with the engaging shaft 47 at the rear end of the moving shaft 36. Since the moving shaft 36 is stationary with respect to the seeding section 23, when the seeding section 23 starts to descend from the uppermost position (12:00 of the clock) (FIG. 11), the seeding section 23 and the hopper 2 are moved.
6 moves in the direction of arrow a on the rear side with respect to the moving shaft 36 and the shutter 30 (movement is blocked by the washer 44) (FIG. 13), and the leveling brush 2 is moved from above the seed fitting hole 31.
7 moves and retreats, and the seed fits into the seed fitting hole 31. Next, since the sowing section 23 is in the counter arrow B direction, which is the frontward movement from the lateral position (9 o'clock of the clock, FIG. 16), the discharge port 29 is aligned with the seed fitting hole 31 and the seed is dropped. , Seeds
Droplets 57 of seeding plate 56 through hose 55 one by one
More fall into pot 2. In this case, since the pressing plate portion 59 having the pressing protrusion 58 is provided on the rear side of the seeding plate portion 56, the concave portion 60 is formed in the upper portion of the soil floor 4 of the pot 2,
When seeds are sown in the recesses 60 and the seeds fall, the seeding plate portion 56 is as close as possible to the upper surface of the pot 2, so that a guiding action is exerted to prevent the seeds from scattering and the seeding accuracy is improved. Is improving. The relationship between the moving shaft 36 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 arrow A due to the elasticity of the spring 40,
The engaging shaft 47 of the moving shaft 36 is engaged with the engaging member 49. The shutter 30 is biased by the spring 43 in the direction of arrow A, but does not move because the regulating member 52 is in contact therewith. In FIG. 12, the seeding section 23 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 that is in contact with the washer 44 does not change, but since the hopper 26 moves together with the seeding section 23, the hopper 26 does not move with respect to the shutter 30. Two
6 moves in the direction of arrow a to move the seed 20 into the seed fitting hole 31.
When the stopper 41 of the moving shaft 36 comes into contact with the front plate 37, the elastic force of the spring 40 does not urge the seeding portion 23 in the direction of arrow A, and the seedling portion 23 is held by 40 and 41. Then, 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 located rearward of the engaging member 49 (FIG. 14). At this time, the engaging member 4
When 9 is removed, 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 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, but is replaced with the washer 44 and the restriction member 52 is engaged by the engagement leg 3.
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 pot sheet 1 having the individual pots 2, it is possible to sow one pot sheet 1 by repeating 5 times, but when the pot sheet 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 is not engaged. There is no relative movement and no seeding. It is also possible to forcibly rotate the support arm 90 by the manual switching device 92 and lower the sensing roller 91. The seeds 20 are coated with vegetable seeds such as lettuce, and not only the size of the seed itself is different even in the same variety, but the size is also different depending on the thickness of the coating. . Therefore, when sowing the seeds of Chinese cabbage after sowing the lettuce, the hopper 26 is removed from the sowing section 23, the shutter 30 on the bottom plate 28 is removed, and the shutter of the seed fitting hole 31 that matches the size of the other seed 20 is released. Thirty
Replace with. Similarly, since several kinds of pot sheets 1 having different intervals between the pots 2 are commercially available, the seeding transfer piece 66 and the feed transfer piece 67 are reciprocally moved in opposite directions, and at a certain point. The transfer piece 67 for feeding is transferred to the transfer piece 66 for seeding, and the moving speed of the transfer piece 67 for feeding until this transfer 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 synchronized with the moving speed of the seeding section 23, and during the return stroke of the seeding section 23, the feeding sheet 67 transfers the pot sheet 1 to the feed start point S. It is being transferred from to the transfer point T. Therefore, the seeding transfer piece 66 and the feed transfer piece 67 move the pot sheet 1 by the distance between the pots 2 to be seeded at once by both (for example, 4 pots out of 20 pots 2), Among these, the movement of the seeding section 23 needs to make the diameters of the crank 25 and the rotary disk 74 for seeding the same so as to be completely matched, but the transporting piece 67 for feeding moves the pot sheet 1 at the takeover point T. After the delivery, it is sufficient to reach the transfer point T at the same time as the returning sowing transfer piece 66. When the moving amount and the moving speed of the feeding transfer piece 67 are changed, the pot sheet 1 having different intervals and different numbers of the pots 2 is 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 takeover point T is a takeover 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.
The pot sheet 1 as a seeding point for advancing and seeding
The number of seeding times by the seeding section 23 is arbitrarily set with respect to the total number of pots 2, and the number of pots 2 to be seeded at one time is obtained by dividing by the set number of seeding times. From the first pot 2 to the last It suffices to match the interval up to the pot 2 with the seeding interval C. When the length of the crank 25 is 40 mm and the number of the pots is 20 and the pot sheet 1 has the pot 2 with an interval of 25 mm, the number of the four pot sheets is 4. When trying to sow the pot 2, the number of sowings is 5, the seeding interval C is 100 mm, and the synchronous sowing interval A is 40 mm, so the feed interval B is 60 mm, and the number of seeds is 18 and the pot 2 with an interval of 25 mm is used. In the case of the pot sheet 1 having the above, when trying to sow three pots 2, the number of sowing is 6, the sowing interval C is 75 mm, and the synchronous sowing interval A is 40 mm.
Is 35 mm. And, even if the number of pots is the same, if the intervals are different, it is possible to deal with it only by changing the feed interval B without changing the synchronous sowing interval A. For example, in the case of the pot sheet 1 having the cranks 25 having a length of 40 mm and the pots 2 having 20 and the intervals of 25 mm, when seeding four pots 2, the number of seeding is 5, and the seeding interval is Since C is 100 mm and the synchronous sowing interval A is 40 mm, the feeding interval B is 60 mm, but in the case of the pot sheet 1 having 20 pots 2 having an interval of 30 mm, 4 pots 2 are seeded. When trying to do so, the number of times of sowing does not change, but the seeding interval C is 120 mm and the synchronous sowing interval A is 40 mm, so the feed interval B may be 80 mm, and the position of the takeover point T does not change. So
The feed start point S is moved to the rear side by 20 mm. At this time,
Corresponding to the change of the feed start point S, the stop switch 76
The start switch 78 is also changed. In the above description, the length of the synchronization sowing interval A is not changed, but
This is a principle, and the length of the synchronous sowing interval A is
The length matches the length of the crank 25, which is set by the moving arc locus of the pressing protrusion 58 of the pressing plate 59, and may be changed depending on the size of the opening of the pot 2, the pressing depth, and the like. is there. In this case, when the length of the crank 25 is 40 mm and the number of the pot sheets 1 is 20 and the number of the pots 2 is 25 mm, the number of the sowing times is 5 when the 4 pots 2 are sowed. Seeding interval C is 1
00 mm and the synchronous sowing interval A is 40 mm, so the feed interval B is 60 mm, but there is no change in the sowing interval C, which is the interval between the pots 2 that are sowed at one time, and only the length of the crank 25 is 50 mm. When changed, the seeding interval C is 1
Since it is 00 mm and the synchronous sowing interval A is 50 mm, it is only necessary to set the feed interval B to 50 mm.

Although it is possible to adjust the height of the seed feeding device 22, this does not align the tip of the feeding transfer piece 67 with the pot upper surface 101 of the pot 2, so that the feeding transfer piece 67 can be adjusted. Too low, front wall of storage box 104 front wall 1
Although it may engage with 13 and lose synchronization with the seeding section 23, in the present invention, since the height of the tip of the feeding transfer piece 67 is matched with the pot upper surface 101 of the pot 2, the front of the storage box 104. It does not engage the wall 113. That is, since the restricting portion 109 of the engagement height adjusting device 112 is in contact with the inclined mounting portion 106 of the feeding transfer piece 67, the feeding transfer piece 67 can freely rotate upward about the horizontal shaft 68. However, since the downward rotation is restricted, the tip height of the feeding transfer piece 67 can be adjusted to the pot upper surface 101 of the pot 2 by changing the contact state between the restricting portion 109 and the bolt 108, and the storage is performed. The front wall 113 of the box 104 passes below the front end of the feeding transfer piece 67, engages the through hole 3 of the pot 2 to transfer the pot sheet 1, and when returning from the transfer point T, pivots upward to retract. Then, the feeding start point S is reached. In this way, the seeding transfer piece 66, the front seeding transfer piece 114, and the front feeding transfer piece 115 are respectively the transfer piece 67 for feeding at the take-over point T.
Therefore, the lower end of each pot is set to be considerably lower than the pot upper surface 101 of the pot 2 so as to surely engage with the through hole 3. Is the front wall 113 of the storage box 104
When so engaged, seeding is not possible, so the seed sheet 23 is positioned above the upper end of the front wall 113, and if it is not swung and does not engage with the through hole 3 of the pot 2, the pot sheet 1 does not move forward, so the seeding portion 23 Since the shutter 30 is not opened, the feeding transfer piece 67 may be engaged at the next opportunity, so there is no problem. Rather than that, the feeding transfer piece 67 is arranged in the first row of the pots 2.
This is because it is more important to engage with the through hole 3 and synchronize with the seeding section 23. Further, since the guide groove 111 at the tip of the guide portion 110 is engaged with the horizontal shaft 68, the regulating portion 109 contacts the upper surface of the bolt 108 without rotating.

[0020]

[Effect] The present invention has a horizontal plate-shaped 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 seedling section 23 is configured by the shutter 30 having the number 1 and the hopper 26 provided on the shutter 30. The seeding section 23 is configured to move in a circle, and vertically below and below the seeding section 23 in a synchronized manner. A seeding transfer piece 66 configured to sow a large number of pots 2 arranged side by side in a pot sheet 1 and reciprocating at the same speed as the seeding section 23, and the sowing transfer piece. In the one provided with a moving mechanism 65 composed of a feeding transfer piece 67 that reciprocates in the opposite direction to 66, the seeding transfer piece 66 is rotatable on a shaft 68, and the tip thereof is the weight of the pot upper surface 101 of the pot 2. Mounted so as to be positioned further downward, the transfer piece 67 for feeding can freely rotate upward on the horizontal shaft 69, but the tip corresponds to the height of the pot upper surface 101 of the pot 2 by the engaging height adjusting device 112. Mounted as Since it is obtained by a seeding device,
The feed transfer piece 67 can freely rotate upward about the horizontal shaft 69, but its downward rotation is restricted. Therefore, by changing the contact state between the restricting portion 109 and the bolt 108, the transfer piece 67 is provided. The tip height of the pot can be adjusted to the pot upper surface 101 of the pot 2, and the front wall 113 of the storage box 104 passes below the tip of the feeding transfer piece 67 and engages only the through hole 3 of the pot 2 to form the pot. The sheet 1 is transferred.
