[0003]

In the above-mentioned known example, the two sprockets c, c are fixed to the rotating shaft, and the chain d is wound around two adjacent sprockets c, c, so that the number of parts is large. There is a problem that the weight is large and the cost is high.

[0004]

It is an object of the present invention to reduce the number of parts and reduce the weight by using one sprocket and one long chain.
It is designed to reduce man-hours and costs.

[0005]

Therefore, according to the present invention, a pair of left and right frames 7, 7 arranged in parallel at a predetermined interval.
, And the left and right rotating shafts 9, 9, ... Axed at predetermined intervals in the length direction of the frame 7, and the transfer rolls 8, 8, ... A sprocket 10 is attached to an end portion of the rotary shaft 9, and the chain 11 wound around the group of sprockets 10 is wound around the sprocket 10 at the front and rear ends as one, and the sprocket 10 at an intermediate position is provided on the upper surface side and the lower surface side thereof. The seedling raising box transfer device is provided with a support rail 18 for preventing slackening of the chain at the lower part of the chain 11 only for engagement.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 is a nursery box transfer table having a transfer device 2 for transferring a nursery box A, which is placed on the floor by supporting legs 3 provided at predetermined intervals. To be done. Above the seedling raising box transfer table 1, a part or all of a bed soil supply device 4, a seed supply device 5, a soil cover supply device 6 or a watering device (not shown) for supplying bed soil is provided. A cleaning device may be provided in the
Any material can be used as long as it can process the nursery box A being transferred.

Reference numeral 7 denotes a pair of left and right frames of the seedling raising box transfer table 1, which are provided at predetermined intervals on the left and right. Both ends of a rotating shaft 9 of a transfer roll 8 are attached to the frame 7, and the transfer roll 8 is provided with a plurality of shafts at predetermined intervals in the front and back to form the transfer device 2. The rotary shaft 9 is projected outward from the frame 7, a sprocket 10 is fixed to the projected portion, and an endless chain 11 is wound around each sprocket 10.
Reference numeral 12 is an inner plate of the endless chain 11, 13 is an outer plate of the endless chain 11, 14 is a pin, and 15 is a roll.

The endless chain 11 is a sprocket 10.
Upper moving chain 16 and sprocket 1 moving on the upper side of
The lower moving chain 17 moves on the lower side of 0, and a chain support rail 18 is provided below the lower moving chain 17. The chain support rail 18 includes a chain receiving portion 19 located below the roll 15 provided between the inner plate 12 and the inner plate 12 of the endless chain 11.
The lower end of the chain receiving portion 19 is bent and attached to the frame 7, and is formed to be long in the moving direction of the endless chain 11. The attaching portion 20 is brought into contact with the outer surface of the frame 7 by the bolt 21. Install.

That is, a single endless chain 11 is wound around the sprockets 10 of the plurality of transfer rolls 8, the chain 11 is wound around the front and rear sprockets 10, and the sprocket 10 at the intermediate position has upper and lower surfaces thereof. Side 1
1 is engaged only, and the chain receiving portion 19 of the chain support rail 18 is located below the lower moving chain 17 of the endless chain 11. Therefore, it is also possible to hang one endless chain 11 from the start end to the end of the seedling raising box transfer table 1 and support it by the chain support rails 18, and in all the transfer rolls 8, several sets. A group of a plurality of transfer rolls 8 is formed, and the chain 11 is wound around the sprocket 10 at the front and rear ends of each of these several sets, and the sprocket 10 at the intermediate position only engages the chain 11 at the upper surface side and the lower surface side. You may do it. Further, there is a case in which one endless chain 11 is supported by chain support rails 18 that are appropriately divided and formed.

As described above, the gist of the present invention is that one endless chain 11 is wound around the sprockets 10 of the plurality of transfer rolls 8 and the chain support rail 18 is provided below the lower moving chain 17 of the endless chain 11. That is to position the chain receiver 19. The chain support rail 18 includes a roll 15 of the endless chain 11 in which the chain receiving portion 19 is in a regular position.
In contrast, it is located at a lower position with a predetermined interval, but a long hole 22 is formed in the mounting portion 20 and the bolt 21 is inserted into the long hole 22 to move the chain support rail 18 to the frame 7. Mount freely up and down. Reference numeral 23 is a motor provided on the seedling raising box transfer table 1, 25 is an output sprocket of the motor 23, and 26 is a passive sprocket provided on the rotary shaft 9 of the desired transfer roll 8, and between the output sprocket 25 and the passive sprocket 26. Put chain 24 around.

[0011]

[Operation] Next, the operation will be described. When the motor 23 is energized,
The rotation of the motor 23 is output to the sprocket 25 and the chain 24.
And a desired transmission sprocket 26 provided on the rotary shaft 9 of the transfer roll 8 transmits this rotation to the sprocket 10 of each transfer roll 8 by the endless chain 11 to rotate all the transfer rolls 8. When the seedling raising box A is supplied to the starting end portion of the seedling raising box transfer base 1, the seedling raising box A is transferred toward the terminal end by the transfer roll 8, the bed soil is supplied by the bed soil supplying device 4, and the seed soil supplying device 5 is used. The seeds are supplied, and the soil cover supplying device 6 supplies the soil to sow the seeds.

In this case, one endless chain 11 is wound around the sprockets 10 of the plurality of transfer rolls 8 and wound around the sprockets 10 at the front and rear ends, and the sprockets 10 at the intermediate position are engaged with the upper surface side and the lower surface side thereof. Since the chain receiving portion 19 of the chain support rail 18 is located below the lower moving chain 17 of the endless chain 11, even if one endless chain 11 is wound over a long distance, Since the lower moving chain 17 is supported by the chain support rail 18, the sprocket 10 of each transfer roll 8 is supported.
Reliably transmit rotation to.

Conventionally, two sprockets are fixed to the rotary shaft 9, but since one endless chain 11 is wound around the sprocket 10, the number of sprockets 10 and the endless chain 11 can be reduced, and the number of man-hours can be reduced. The cost can be reduced.

[0014]

According to the present invention, a pair of left and right frames 7, 7 are arranged in parallel at a predetermined interval, and left and right rotating shafts 9, 9 are axially mounted at a predetermined interval in the length direction of the frame 7. …
, And the transfer rolls 8, 8 fixed to the rotating shaft 9, a sprocket 10 is attached to an end of the rotating shaft 9, and the chain 11 wound around the sprocket group 10 is one. The sprocket 10 at the front and rear ends is wound around, and the sprocket 10 at the intermediate position is engaged only with the upper surface side and the lower surface side thereof, and a support rail 18 for preventing slackening of the chain is provided under the chain 11. Since the transfer device is used, one endless chain 11 can be wound around the sprockets 10 of the plurality of transfer rolls 8, and the number of parts can be reduced, the number of assembling steps can be reduced, and the cost can be reduced.
