[0003]

The above-mentioned well-known examples are originally
Since it is used alone as a soil supplying device or a sowing device, there is a problem that continuous operation is difficult. That is, since the independent transfer stands are driven individually, if they are simply connected, the transfer speed of the seedling raising container will be different and the transfer of the seedling raising container will be impaired, so that they cannot be connected. In particular, in order to improve versatility, in the case of a transfer table using a variable speed motor, there is an obstacle in transfer, and in the case of an auxiliary transfer table having transfer means such as a mere freely rotating transfer roll or transfer belt. Since the rotation transmission is troublesome, it is not integrally formed from the beginning and connected later. Therefore, even if the transfer table originally has independent transfer means, if a plurality of transfer tables are connected, continuous work becomes possible.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Is a transfer table 1 for transferring the seedling raising container, which is formed long in the transfer direction of the seedling raising container, and is placed on the floor by supporting legs provided at predetermined intervals (not shown). A transfer device (not shown) such as a transfer roll or a transfer belt driven by (omitted) is provided, and a processing device (not shown) such as a soil supply device, a seeding device, or a washing device for seedling raising containers is provided.

Thus, the start end or the end of the transfer table 1 is connected to the end or start of another transfer table 1 via the rotation transmission connection device 2. This is the gist of the present invention. That is, originally, when another transfer table 1 is connected to the transfer table 1, since each of them is driven separately, the transfer speed of the seedling raising container is different and the transfer of the seedling raising container is disturbed. This is possible, and particularly in the case of the transfer table 1 that uses a variable speed motor in order to improve versatility, it is difficult to synchronize the transfer speeds, which causes an obstacle to the transfer. Further, in the case of the auxiliary transfer base 1 having a transfer means such as a transfer roller or a transfer belt which can be freely rotated, the rotation transmission is troublesome, so that it is not integrally formed from the beginning and connected later. The rotation transmission connection device 2 has a pair of frame side plates 4 of a box-shaped frame 3 on which a one-side rotation transmission shaft 5 is rotatably mounted. An engagement portion 6 is formed on the one-side rotation transmission shaft 5, and a transfer table side engagement portion 8 provided on the transfer table side rotation shaft 7 of the transfer table 1 is engaged with the engagement portion 6. One side gear 9 is fixed to one side rotation transmission shaft 5 in the frame 3.

Therefore, the other transfer table side rotary shaft 15 of the other transfer table 1 is provided with the other transfer table side engaging portion 16, and the other transfer table side engaging portion 16 is provided with the other side rotation transmission shaft 17. The other rotation transmission side engaging portion 18 provided is engaged. The other side rotation transmitting shaft 17 is rotatably mounted on a pair of moving side plates 20 of a moving body 19 formed in a U-shape in plan view. The pair of left and right moving side plates 20 are provided with engaging protrusions 21 that protrude vertically. A vertical elongated hole 22 is formed in the frame side plate 4, and a long elongated hole 23 is formed following the vertical elongated hole 22 toward the one side rotation transmission shaft 5 side. Then, the engaging protrusions 21 are fitted through the vertically elongated holes 22, the moving side plate 20 is slidably contacted with the inner surface of the frame side plate 4, and the engaging protrusions 21 are slidably contacted with and engaged with the outer surface of the frame side plate 4. The inside is configured such that the other side rotation transmission shaft 17 is movable. In addition,
It is expected that the moving side plate 20 of the moving body 19 slides on the inner surface of the frame side plate 4 and guides the movement of the moving body 19.

Therefore, the other side gear 24 is fixed to the other side rotation transmission shaft 17, and the endless chain 25 is wound between the other side gear 24 and the one side gear 9. One end of a moving shaft 26 in the front-rear direction is fixed to the moving body 19, and the other end of the moving shaft 26 is slidably inserted into an insertion hole 28 of a stay 27 fixed to the frame 3 to allow the stay 27 and the moving body to move. 19
A spring 29 is provided on the moving shaft 26 between the two, and the spring 29 urges the endless chain 25 so that the other gear 24 moves in a direction in which the endless chain 25 is always tensioned. Reference numeral 30 is a stopper pin provided on the moving shaft 26.

[0010]

Next, the operation will be described. The terminal ends of the transfer table 1 on the other side are arranged near the start end part of the transfer table 1 on the one side at an arbitrary interval, and then the other transfer of the rotary shaft 15 on the other transfer table side of the transfer table 1 on the other side is performed. The other rotation transmitting side engaging portion 18 of the other side rotation transmitting shaft 17 of the rotation transmitting connecting device 2 is engaged with the table side engaging portion 16. Next, while holding the frame 3, the engagement portion 6 of the one-side rotation transmission shaft 5 of the rotation transmission connection device 2 is aligned with the transfer table side engagement portion 8 of the transfer table side rotation shaft 7 of the transfer table 1 and engaged. When the part 6 and the transfer table side engaging part 8 are engaged, the connection of the two transfer tables 1 is completed.

In this case, the other side rotation transmitting shaft 17 is mounted on the moving side plate 20, and the moving side plate 20 is movable in the frame 3 in the tensioning direction of the endless chain 25. When the frame 3 and the other-side rotation transmission shaft 17 are relatively moved in a state of being engaged with the other-side transport table-side rotation shaft 15 of the transport table 1, the engaging portion 6 of the one-side rotation transmission shaft 5 causes the transport table 1 to move. It can be connected easily by matching with the transfer table side engaging portion 8 of the transfer table side rotating shaft 7. Therefore, when the motor of the transfer table 1 on one side is driven, the rotation shaft 7 on the transfer table side rotates, and the rotation of the rotation shaft 7 on the transfer table side rotates via the engagement parts 8 and 6 on the transfer table side. The one-side rotation transmission shaft 5 rotates the one-side gear 9, the rotation of the one-side gear 9 is transmitted to the other-side gear 24 by the endless chain 25, and the rotation of the other-side gear 24 is transmitted to the other-side gear 24. Transmission to the other transfer table side engaging portion 16 of the other transfer table 1 via the side rotation transmitting shaft 17, the other rotation transmitting side engaging portion 18 and the other transfer table side engaging portion 16, and transfer of the other side The table 1 is rotated at the same transfer speed as the transfer table 1 on one side.

Therefore, when the soil supplying device is provided on the transfer table 1 on the other side and the seeding device is provided on the transfer table 1 on the one side,
The nursery containers are reliably transported and may receive soil and seed supplies during the transport. It is also possible to provide a cleaning device on each transfer table 1 and continuously wash the seedling raising container. It is of course possible to drive the transfer table 1 on the other side and operate the transfer table 1 on the one side. In this case, preferably, if the one-side gear 9 is set to the driving side and the upper endless chain 25 is rotated so as to be pulled, the endless chain 25 can be prevented from coming off. That is, when the rotation transmission connecting device 2 is connected to the other transfer table side rotating shaft 15 on the other side, the rotation transfer connecting device 2 is inverted and used in FIG.
6 is engaged with the engaging portion 6 of the one-sided rotation transmission shaft 5 (see FIG.
Is synonymous with flipping upside down). Therefore, the rotation transmission connection device 2 can be attached to the transfer table 1 at any position.
It can be installed in any place.

As described above, by connecting the plurality of transfer tables 1 with the rotation transmission connection device 2, various operations can be continuously performed. In this case, it does not matter whether or not each transfer table 1 is provided with a transfer motor, but when each has a motor, one of them is used. Therefore, the rotation transmission connection device 2 includes the frame 3, the two shafts, and the moving body 1.
Since it can be constituted by 9 and the spring 29, the number of parts is small and the cost can be reduced. In this case, since the transfer speed of the seedling raising container of the seeding device is not so fast, the distance between the one-side rotation transmission shaft 5 and the other-side rotation transmission shaft 17 becomes narrower than the length of the endless chain 25, and the endless chain 25 comes loose even if loose. However, after connecting each of the one-side rotation transmission shaft 5 and the other-side rotation transmission shaft 17 to the transfer table-side rotation shaft 7 and the other transfer table-side rotation shaft 15 of the transfer table 1, the respective transfer tables 1 are connected. A method of mounting the endless chain 25 until it is tensioned is also effective, and a tension gear 34 may be provided as shown in FIG.

Since the moving body 19 is composed of a pair of moving side plates 20 that are in sliding contact with the inner surfaces of the left and right frame side plates 4 of the frame 3, the moving body 19 can move smoothly and reliably without providing a special guide. You can do it. Therefore, the stay 27 acts as a bearing of the moving shaft 26, a guide of the moving body 19, and a stopper of the spring 29, and the rotation transmission connecting device 2 is provided.
Can be simplified. The rotation transmission connection device 2 may be assembled in any order and may be used in any manner, and is not limited to the above embodiment.

[0015]

According to the present invention, the frame 3 having the pair of frame side plates 4, the one side rotation transmission shaft 5 provided on the frame side plate 4 with the one side gear 9 mounted on the frame side plate 4 and the one side gear 9 are provided. The other side rotation transmission shaft 1 which has the other side gear 24 around which the endless chain 25 is wound and is rotatably mounted on the frame side plate 4 so as to be movable in the tension direction of the endless chain 25.
7, and the end portions of the one-side rotation transmission shaft 5 and the other-side rotation transmission shaft 17 are provided on the transfer table-side rotation shafts of a plurality of transfer tables 1 each independently having a seedling raising container transfer means. Since it is a rotation transmission connection device of a seedling raising box transfer table, each of which is provided with an engaging part that engages with the transfer table side engaging part and can transmit rotation, a transfer table provided with a soil supplying device. By connecting the transfer table 1 provided with the seeding device to 1, it is possible to perform the supply of soil and seeds in a continuous operation, and it is also possible to connect various transfer boxes for seedling raising boxes into a continuous operation, It is possible to improve work efficiency and versatility of continuous work. Further, since the end portions of the one-side rotation transmission shaft 5 and the other-side rotation transmission shaft 17 may be connected to the respective transfer base side rotary shafts of the plurality of transfer bases 1,
The rotation transmission connection device 2 can be attached to any side surface of the transfer table 1 and can be attached at any attachment position. Therefore, the rotation transmission connection device 2 is easy to attach, does not interfere with work, and improves workability. According to the present invention, the other side rotation transmission shaft 17 is axially mounted on a pair of moving side plates 20 of a moving body 19 that moves by sliding contact with the inner surface of the frame side plate 4.
A pair of upper and lower engaging projections 21 that are slidably engaged with the outer surface of the frame, and the frame side plate 4 has a vertically long hole 22 that intersects the moving direction of the moving body 19 and into which the engaging projection 21 can be inserted. Since the rotation transmission connection device of the transfer table for the nursery box is formed with the horizontally elongated hole 23 through which the other side rotation transmission shaft 17 can move following the hole 22, the frame 3 of the rotation transmission connection device is formed.
By relatively moving the other-side rotation transmitting shaft 17 and the other-side rotation transmitting shaft 17, it is possible to easily connect the one-side rotation transmitting shaft 5 and the other-side rotation transmitting shaft 17. Since the present invention is a rotation transmission connection device for a nursery box transfer table, which is provided with a tension gear 34 between the one-side gear 9 and the other-side gear 24,
The endless chain 25 can be completely prevented from being loosened, which further ensures the work.
