DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Hitherto, a stacking device in which a fast-forwarding roll is provided at an end portion of a seedling device for a nursery box, and a receiving bar which receives the seedling-growing box and descends following the fast-forwarding roll is known.

[0003]

In the case of the known device, there is a problem in feeding by the rapid traverse roll, and the feeding cannot be completed completely. That is, when the seedling box is fed by the roll, the seedling box cannot be sent completely due to a lack of the coefficient of friction.

[0004]

According to the present invention, there is provided a stacking device 22 provided with a receiving bar 34 for receiving the seeded seedling box 5 and descending at the end of the transfer table 1 of the seedling box seeding device. In the present invention, a seedling box stacking device of a seedling box sowing device is provided with a fast-forward belt stand 32 around which a fast-forward belt 33 is wound, between the transfer table 1 and the receiving bar 34.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a transfer table, which is horizontally mounted on a floor 2 by supporting legs 3 and 3. The transfer table 1 is publicly known, is formed to be long in the transfer direction of the seedling raising box 7, and is provided with transfer rollers 4, 4 at predetermined intervals. Since the transfer roll 4 is a means for transferring the seedling box 5, a transfer belt may be used instead of the transfer roll 4. Reference numeral 6 denotes a supply side of the seedling raising box 5, and 7 denotes 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 directed toward the take-out side 7 by the transfer roll 4 rotating by a motor. Send sideways.

[0006] On the transfer table 1, a floor soil supply device 8, a seeding device 9, a covering soil supply device 10, and the like are provided in this order. 11 is a hopper of the floor soil supply device 8, 12 is the feeding belt, 13 is floor soil, and between the floor soil supply device 8 and the seeding device 9,
Floor soil leveling brush 14 for leveling the floor soil 13 in the nursery box 5
Is attached. Reference numeral 15 denotes a seed hopper of the sowing device 9;
Is a feeding roll, and 17 is a seed. A motor 18 for driving the transfer roll 4 and the like is provided between the seeding device 9 and the cover feeding device 10. 19 is a hopper of the earth covering supply device 10, 20 is the feeding belt, and 21 is earth covering.

[0007] A stacking device 22 for the seedling raising box 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 left pillars 24, 24 on the front, rear, left and right,
An upper rotation shaft 25 and a lower rotation shaft 26 are fixed to the upper and lower sides of the right column 23 and the left column 24 on the near side, respectively, and the right column 23 on the other side is fixed.
And upper and lower rotating shafts 25 and 26 above and below the left column 24, respectively.
To each. Upper and lower sprockets 27 and 27 are fixed to the left and right sides of the upper and lower rotation shafts 25 on the front side and the rear side, respectively, and lower and upper sprockets 27 and 27 are fixed to the lower rotation shaft 26, respectively. At the same time, chains 29 and 29 are respectively wound around.

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 2 on the near side and the other side
Fast-forward belt table 3 protruding in the direction of transfer table 1 from 3 and 23
2 is provided, and a fast-forward belt 33 is attached to the fast-forward belt table 32. The fast-forward belt 33 is connected to the motor 30.
To rotate. That is, a pair of drive pulleys 41 is provided on the shaft 36 of the guide roll 35 on the left and right,
2, a shaft 42 corresponding to the shaft 36 is provided. The shaft 42 is provided with a passive pulley 44 in addition to the guide roll 43. The drive pulley 41 and the passive pulley 44 A fast-forward belt 33 is wound therebetween. Reference numeral 45 denotes a guide plate for guiding the nursery box 5. The shaft 42 is always moved in the belt tension direction by a spring 46. 47 is a scraper.

[0009] The left and right chains 29, 29 are provided with receiving bars 34 which are moved by a fast-forward belt 33. Since the left and right chains 29, 29 are mounted via the one-rotation clutch 31, the receiving beam 34 is stopped at a position where it can be transferred from the fast-forward belt 33. Stopped at a slightly lower position. This is to ensure that the nursery box 5 can be sent to the receiving bar 34 by the fast-forward belt 33. A feed pawl 37 is provided on the shaft 36 of the guide roll 35 at the end of the fast-forward belt 33. Reference numeral 38 denotes a U-shaped bracket, and the U-shaped bracket 3
8, two pins 39 are attached so as to protrude with a spring 40 across the shaft 36. Then, even in the seedling raising box 5 having a different bottom shape, the pin 39 can be sent to the seedling box 5 with the tip touching the bottom surface, and finally the bottom part of the seedling raising box 5 can be pushed out by the pin 39 and sent out to the receiving tray 34. The one-turn clutch 31 is turned ON when one seedling box 5 is securely mounted on the receiving bar 34, and the motor 30 rotates the chain 29 to stack the seedling boxes 5 downward. For example, ten seedling boxes 5 Are stacked, another motor 4
0 is turned on and sent to the extraction unit 41.

[0011]

Next, the operation 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 the seedling box 5 passes below the floor soil supply device 8, it is supplied with the floor soil 13 and passes under the seeding device 9. When passing, the seed paddy 17 is sown, and when passing below the covering device 10, the covering material 21 is supplied 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. Rapid feed belt 3
The motor 3 is rotated faster than the transfer roll 4 by the motor 30, so that the motor 3 is fast-forwarded and moves on to the receiving tray 34 of the stacking device 22.

[0012]

According to the present invention, there is provided a transfer table 1 for a seeding apparatus for a nursery box.
Receiving the seedling box 5 that has been sown at the end of
And a seedling box of a seedling box seeding apparatus in which a fast-forward belt stand 32 around which a fast-forward belt 33 is wound is provided between the transfer table 1 and the receiving bar 34. Since the stacking device is used, the friction coefficient is larger than that of the conventional rapid-forwarding roll, and the seedling raising box 5 can be fed reliably.
