BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling box stacking device for a seedling box sowing device.

0002

2. Description of the Related Art Hitherto, a stacking device has been known in which a fast-feeding roll is provided at the end of a seeding device for seedling-growing boxes, and a receiving bar that receives and descends the seedling-growing box follows the fast-feeding roll.

0003

[Problems to be Solved by the Invention] In the known method, there was a problem in feeding with a rapid-feeding roll, and there were cases where complete feeding was not possible.

0004

[Means for Solving the Problems] Accordingly, the present invention provides a fast-feeding belt 33 at the terminal end of a seedling-growing box sowing device, and following the fast-feeding belt 33, a support bar 34 that receives the seedling-growing box 5 and descends.
In the stacking device, a pin 39 is provided at the terminal end of the fast-feeding belt 33 to engage with the bottom surface of the seedling box 5 and rotate.
This is a seedling box stacking device of a seedling box sowing device equipped with a feed pawl wheel 37 having a feed wheel 37.

[0005]

[Example] An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a transfer table, which is placed horizontally on a floor 2 by supporting legs 3, 3. The transfer stand 1 is well known and is formed long in the direction of transfer of the seedling box 7, and has transfer rolls 4, 4 attached thereto at a predetermined interval. Since the transfer roll 4 is a means for transferring the seedling raising box 5, a transfer belt may be used instead of the transfer roll 4. 6 is a supply side of the seedling raising box 5, and 7 is a take-out side of the seedling raising box. When the seedling raising box 5 is supplied and placed on the supply side 6, it is transported horizontally toward the take-out side 7 by a transfer roll 4 rotated by a motor.

[0006] On the transfer table 1, a bed soil supply device 8, a seeding device 9, a covering soil supply device 10, etc. are provided in this order. 11 is the hopper of the bed soil supply device 8, 12 is the same feeding belt, 13 is the bed soil, and between the bed soil supply device 8 and the seeding device 9,
Soil leveling brush 14 for leveling the soil bed 13 in the seedling raising box 5
is installed.

Reference numeral 15 is a seed hopper of the seeding device 9, 16 is a feed roll thereof, and 17 is a seed. A motor 18 for driving the transfer roll 4, etc. is provided between the seeding device 9 and the soil covering supply device 10. 19 is a hopper of the soil covering supply device 10;
20 is the same feeding belt, and 21 is soil covering.

A stacking device 22 for seedling growing boxes 5 is provided on the floor 2 at the extension of the take-out side 7. The stacking device 22 is provided with four right pillars 23, 23 and four left pillars 24, 24 on the front, rear, left and right sides,
The upper and lower rotation shafts 25 and 26 are respectively fixed above and below the right column 23 and left column 24 on the near side, and the right column 23 on the far side is fixed.
Also above and below the left column 24 are an upper rotating shaft 25 and a lower rotating shaft 26.
are each fixed on the shaft.

Upper sprockets 27, 27 are located on the left and right sides of the upper rotating shaft 25 on the near side and on the far side, and the lower rotating shaft 25
Lower sprockets 28, 28 are respectively fixed to 6, and chains 29, 29 are wound around the left and right upper sprockets 27, 27 and lower sprockets 28, 28, respectively.

A motor 30 for rotating the chain 29 is provided at a lower position. The motor 30 is always energized, and a one-turn clutch 31 is provided between the chain 29 and the motor 30. Right pillar 23 on this side and on the far side
, 23, there is a fast-feeding belt stand 32 protruding in one direction of the transfer table.
is provided, and the fast-feeding belt 3 is mounted on the fast-feeding belt stand 32.
3 is installed. The fast feed belt 33 is rotated by the motor 30.

[0011] The left and right chains 29, 29 are provided with a receiving crosspiece 34 which is transferred from a fast-forwarding belt 33. Since the left and right chains 29, 29 are attached via a one-turn clutch 31, the receiving bar 34 is stopped at a position where it can be transferred from the fast-feeding belt 33. To be precise, the receiving bar 34 is attached to the fast-feeding belt 33. It is stopped at a position slightly lower than the surface. This is to ensure that the seedling box 5 can be sent to the receiving frame 34 using the fast-forwarding belt 33.

Even so, since the seedling box 5 is not completely fed by the fast feed belt 33, a feed pawl wheel 37 is provided on the shaft 36 of the guide roll 35 at the end of the fast feed belt 33. Reference numeral 38 denotes a U-shaped metal fitting, and two pins 39 are attached to the U-shaped metal fitting 38 so as to straddle the shaft 36 and project with a spring 40. Then, even if the seedling raising box 5 has a different bottom shape, the tip of the seedling raising box 5 hits the bottom surface with the pin 39 and is fed, and finally the pin 39 pushes the bottom of the seedling raising box 5 and sends it out to the receiving holder 34.

The one-rotation clutch 31 is turned ON when one seedling box 5 is securely placed on the receiving frame 34, and the motor 30 rotates the chain 29 to stack the seedling boxes 5 downward, stacking, for example, 10 seedling boxes. 5 is stacked, the motor 40 is turned on.
Then, it is sent to the take-out section 41.

[0014]

[Effect] Next, the effect will be described. When the seedling raising box 5 is placed on the transfer roll 4 of the transfer table 1 and transferred by the transfer table 1, when it passes under the bed soil supply device 8, it receives a supply of bed soil 13 and passes under the seeding device 9. When the seed rice 17 was sown,
When passing under the covering soil supply device 10, the covering soil 21 is supplied and reaches the terminal end portion 7. At the terminal end 7, the fast-feeding belt stand 3
2, but the fast-forwarding belt 33
Since it is rotated faster than the transfer roll 4 by the motor 30, it is fast-forwarded and transferred to the receiving crosspiece 34 of the stacking device 22. At this time, since the receiving bar 34 is slightly lower than the surface of the fast-forwarding belt 33, only the tip contacts it as shown in FIG.
The contact resistance is small, and the rapid feed belt 33 allows smooth feeding. Although some seedling raising boxes 5 have different bottom shapes, a feed pawl wheel 37 is provided at the end of the fast feed belt 33 and has a pin 39 that protrudes elastically due to the elasticity of a spring 36. Since the wheel 37 is rotating, the pin 39
The tip of the seedling box 5 engages with the bottom surface of the seedling box 5 to smoothly feed the seedlings, and finally the pin 39 pushes the bottom of the seedling box 5 to completely transfer the seedlings.

[0015]

Effects of the Invention The present invention provides a stacking device in which a fast-feeding belt 33 is provided at the terminal end of a seedling-raising box sowing device, and a receiving bar 34 that receives and descends the seedling-growing box 5 following the fast-feeding belt 33 is provided. At the end of the fast-feed belt 33, there is a feed pawl wheel 3 having a pin 39 that engages with the bottom surface of the seedling box 5 and rotates.
Since the seedling box stacking device of the seedling box seeding device is provided with the seedling box 7, the seedling growing boxes 5 can be reliably fed onto the receiving bar 34 of the stacking device 22.
