The scraper 27 is attached to the attachment member 31 such that the central portion is located on the rearmost side and is located on the front side as it reaches both left and right sides, thereby improving the scraping of mud. Scraper 2
7 is located immediately above or behind the left and right passive rollers 43 of the fast-forward belt 33. The fast-forward belt 3
The left and right drive rollers 35 face the vicinity of the front chain 29, and the drive that engages with the engagement holes 75 on both the left and right sides of the seedling raising container 5 is located above one of the left and right drive rollers 35. A ratchet wheel 80 is provided. The driving ratchet wheel 80 is fixed to a connecting shaft 81 in the left-right direction, and both ends of the connecting shaft 81 are rotatably mounted on tips of a pair of left and right arms 82, respectively.
The base of each arm 82 is rotatably mounted on a fixed portion 83. Then, the rotation of the motor 30 is transmitted to the rotating shaft 86 of the driving roller 35, and the rotation of the rotating shaft 86 is transmitted to the connecting shaft 81 so that the driving ratchet wheel 80 and the driving roller 35 rotate at the same peripheral speed. To be configured. 84 is a spring that urges downward, 87 is an endless chain that is rotated by the motor 30, 88 is a pulley, 89 is a transmission belt that expands and contracts to some extent, and transmits rotation even when the driving ratchet wheel 80 moves up and down.

A pair of front and rear chains 29, 29 are provided with receiving bars 34, which move on from a fast-forward belt 33. A pair of front and rear chains 29, 29 are provided on the left and right, and a group of chains 29 is rotated by driving a motor 39 by a sensor 38. In the embodiment, the chains 29, 29 have a pair
Since the motor 4 is provided, when one of them descends, it comes into contact with the sensor 40 to stop the motor 39 and wait the other. A receiving table 41 is provided below the receiving bars 34, 34. Cradle 41
Is constituted by a pair of left and right transport belts 42 and a freely rotating support roller 43 for supporting the transport belts 42. When a predetermined number of seedling growing containers 1 are stacked on the transport belt 42, the motor 4
4 to rotate the transport belt 42,
To 5. Accordingly, the cradle 41 is provided with
It has the function of receiving and supporting, and the function of carrying and taking out. In addition, the transfer unit 45 has a freely rotating wheel 46 arranged side by side, receives the stepped seedling raising container 1 on the wheel 46, and takes it out by any means.

[0012]

Next, the operation will be described. Support rail 76 of transfer table 1
When the feeding is performed so that the sliding contact portion 77 of the seedling raising container 5 is positioned above, the transfer ratchet 4 is engaged with the engaging hole 75 of the seedling raising container 5 and transferred, and each pot 74 of the seedling raising container 5 is supplied with floor soil. When passing through the lower part of the device 8, the floor soil 13 is supplied and the seeding device 9 is supplied.
The seeds 17 are sown when passing below, and the covering 21 is supplied when passing below the covering device 10 to reach the terminal end 7. At the end portion 7, the user moves on to the fast-forward belt 33 of the fast-forward belt table 32. The fast-forward belt 33 is
Since it is rotating faster than the transfer pawl 4 due to 0, it is fast-forwarded and moves on to the receiving rail 34 of the stacking device 22.

In this case, since the scraper 27 is provided at a predetermined position behind the fast-forward belt table 32,
The upper surface slides on the lower surface of the scraper 27 to remove excess soil. Therefore, the soil does not fall below the fast-forward belt table 32 and the soil is not dropped by the fast-forward mechanism. Then
At a position above the left and right driving rollers 35, a pair of left and right driving pawls 80 that engage with the engaging holes 75 on both left and right sides of the seedling raising container 5 are provided, and the driving pawl 80 and the driving roller 35 are the same. Because it is configured to rotate at the peripheral speed,
The seedling raising container 5 pushes up the driving ratchet wheel 80, the driving ratchet wheel 80 is rotated by the arm 82, the driving ratchet wheel 80 is engaged with the engaging hole 75 and transferred, and the terminal portion of the seedling raising container 5 is also driven. The sheet is nipped by the drive roller 35 and the roller 80 and sent toward the stacking device 22, and is reliably transferred to the receiving rail 34 of the stacking device 22. That is, in the transfer by the drive roller 35, when the frictional resistance between the seedling raising container 5 and the bottom surface becomes small, the slip occurs,
In particular, at the end of the seedling raising container 5, the weight applied to the drive roller 35 is reduced, so that it is easy to slip. However, since the drive ratchet wheel 80 is engaged with the engagement hole 75, the slip is prevented, and the transfer is ensured. In addition, since the pinion is vertically held by the driving ratchet wheel 80 and the driving roller 35 and rotates at the same peripheral speed, the rotation of the driving roller 35 works well for the transfer of the seedling growing container 5.

Then, the seedling raising container 5 hits the sensor 38 and the motor 39 rotates. Then, the lower rotating shaft 26 rotates, and the lower rotating shaft 26 rotates the chains 29, 29. The seedling raising container 5 that has been transferred to the container 34 descends and is stacked by the receiving bar 34, and is received by the receiving bar 34.
Contacts the sensor 40 to stop the motor 39, and the other receiving beam 34 reaches the standby position. In this case, the receiving bar 34 can be freely rotated upward with respect to the chain 29, but is mounted so as not to rotate downward. Therefore, when descending, it supports the seedling raising container 5 and moves the first stage seedling raising container 5 When it is lowered, it retreats downward as it is, and when it is in the second stage, it comes into contact with the upper surface of the stacked seedling raising containers 5 and turns upward to retreat.

When the above operation is repeated, the pedestal 4
When a predetermined number of seedling raising containers 5 are stacked on the transport belt 42 constituting 1 and this is detected, the transport belt 42 is driven to rotate, transported to the transfer unit 45, and taken out by any means. Since the scraper 27 is provided at a predetermined position at the rear of the fast-forward belt table 32, excess soil on the upper surface of the seedling raising container 5 to which the covering soil 21 has been supplied can be removed. The soil can be prevented from falling on the device, ensuring operation and facilitating maintenance. In addition, below the fast-forward belt table 32,
Even if 8 is provided, since the soil does not fall above it, it does not affect the operation of the floor plate supply device 48.

[0016]

According to the present invention, a pair of left and right receiving bars 34, which descend by slidingly placing the seedling container 5 at the end of the transfer table 1 capable of transferring the seedling container 5, are lowered. A fast-forward belt 33 is provided between the receiving tray 34 in standby and the terminal end of the transfer table 1 in the one provided with the receiving stand 41 for supporting the seedling raising container 5. Since the seedling raising container stacking device is provided with a scraper 27 that slides on the upper surface of the container 5 and removes excess soil, the excess soil on the upper surface of the seedling raising container 5 to which the covering soil 21 is supplied can be removed. It is possible to prevent the soil from dropping into the fast-forward device provided on the fast-forward belt table 32, to ensure operation, and to facilitate maintenance.
