Abstract

PURPOSE:To surely deliver a raising seedling box by providing a pair of driving claw wheels to be engaged with engaging holes on the right and left sides of the raising seedling box, and rotating the driving claw wheels at the same circumferential speed as that of a driving roller. CONSTITUTION:A pair of right and left driving claw wheels 80 to be engaged with engaging holes 75 on the right and left sides of a raising seedling box 5 are provided to the upper part of a driving roller 35 of a fast forwarding roller 33 mounted on the end part of a transfer table 1 of the raising seedling box 5, and the driving claw wheels 80 are rotated at the same circumferential speed with that of the driving roller 35. This allows the raising seedling box 5 to push up the driving claw wheels 80, and the box is held by the driving roller 35 in the condition where the driving claw wheels 80 are engaged with the engaging holes 75 to allow the raising seedling box 5 to be surely transferred onto a receiving machine 34 of a stacking device. In the transfer by the driving roller 35, the friction coefficient between the driving roller and the bottom surface of the raising seedling box 5 becomes small, and the weight applied on the driving roller 35 becomes small at the end part of the raising seedling box 5 to make the box easily slippable. But, the slip can be prevented to surely transfer the box because the driving claw wheels 80 are engaged with the engaging holes 75.

[0013]

[Operation] Next, the operation will be described. Support rail 76 of transfer stand 1
When supplying so that the sliding contact portion 77 of the seedling-growing box 5 is located above, the transfer claw wheel 4 engages with the engaging hole 75 of the seedling-growing box 5 and transfers it, and each pot 74 of the seedling-growing box 5 supplies the ground soil. When it passes below the device 8, it receives the supply of the soil bed 13, and when it passes below the seeding device 9, the seed paddy 17 is sown, and the soil cover supplying device 10
When passing below, the covering soil 21 is supplied to reach the terminal end portion 7. At the terminal end portion 7, the fast-forwarding belt 33 of the fast-forwarding belt base 32 is transferred. Since the fast-forward belt 33 is rotated faster than the transfer claw wheel 4 by the motor 30, the fast-forward belt 33 is fast-forwarded and transferred to the receiving bar 34 of the stacking device 22.

In this case, a pair of left and right drive claw wheels 80 that engage with the left and right engaging holes 75 of the seedling raising box 5 are provided above the left and right drive rollers 35.
Since the driving roller 35 and the driving roller 35 are configured to rotate at the same peripheral speed, the seedling raising box 5 pushes up the driving ratchet wheel 80, the driving ratchet wheel 80 is rotated by the arm 82, and the driving ratchet wheel 80 is engaged. The seedling raising box 5 is transported by being engaged with it, and the terminal end portion of the seedling raising box 5 is also sandwiched by the driving claw wheel 80 and the driving roller 35 and sent toward the stacking device 22, and surely rides on the receiving bar 34 of the stacking device 22. Transfer. That is, in the transfer by the drive roller 35, if the frictional resistance between the seedling raising box 5 and the bottom surface becomes small, it will slip, and especially at the terminal end of the seedling raising box 5, the weight applied to the drive roller 35 will be light, so it will easily slip. ,
Since the drive ratchet wheel 80 is engaged with the engagement hole 75, slipping is prevented and it is reliably transported, and it is held vertically by the drive ratchet wheel 80 and the drive roller 35 to rotate at the same peripheral speed. Therefore, the rotation of the drive roller 35 favorably acts on the transfer of the seedling raising box 5.

Then, the seedling raising box 5 abuts against the abutting portion 49 and rotates the rotary shaft 55 via the horizontal link 51, the L-shaped link 52, the vertical link 53 and the arm 54. Rotating shaft 55
When is rotated, the operating rod 56 is rotated, the engagement between the bent portion 57 and the pin 59 is released, the shaft 58 is moved in the direction of the gear 61 by the spring 60, and the claw 63 of the shaft 58 and the claw 62 of the gear 61 are engaged. Then, the one rotation clutch 31 is rotated once by the motor 30.

Then, the lower rotary shafts 26 are respectively rotated, the lower rotary shafts 26 rotate the chains 29, 29, and the seedling raising box 5 transferred to the receiving bar 34 of the stacking device 22 receives the receiving bar 3
It is lowered by 4 and stacked. Then, the pin 59 also makes one rotation, comes into contact with the bent portion 57, moves the shaft 58 against the elastic force of the spring 60, disengages the claws 62 and 63, and stops the rotation of the receiving bar 34. .

[0017]

The present invention provides a seedling raising box 5 in which a large number of pots 74 are formed on a thin plate 73 made of synthetic resin at predetermined intervals in the front, rear, left and right, and engaging holes 75 are juxtaposed on the left and right sides of the thin plate 73. A fast feed belt 33 provided at the end of the transfer table 1 that can be transferred
And a receiving bar 34 for stacking by descending and stacking the seedling raising box 5 provided following the rapid feeding belt 33, and a pair of left and right contacting the bottom surface of the seedling raising box 5 on the terminal end side of the rapid feeding belt 33. The driving roller 35 and the driving claw wheel 80 which is provided above the roller 35 and engages with the engaging hole 75 from above and rotates at the same peripheral speed as the roller 35 are provided as a seedling raising box stacking device. Drive claw wheel 8
Since 0 is engaged with the engagement hole 75, slipping is prevented, the transfer is reliably carried out, and the drive claw wheel 80 and the drive roller 35 hold it vertically to rotate at the same peripheral speed. There is an effect that the rotation of the drive roller 35 favorably acts on the transfer of the nursery box 5.
