Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pot sheet soil supply device.

[0002]

2. Description of the Related Art Conventionally, a pot sheet in which upper portions of pots are vertically and horizontally connected by connecting portions and engaging holes are formed on both left and right sides at predetermined intervals, a transfer table for laterally transferring the pot sheet, and a transfer table of the transfer table. It consists of an upper supply hopper provided in an upper position and a drive roller below the supply hopper, and a floor soil supply device having a soil feeding belt wound around a passive roller, the drive roller engaging the pot sheet during transfer. It is publicly known that it is configured to rotate by an engaging ratchet wheel that engages with a dowel hole and rotates.

[0003]

The above-mentioned known example has a problem that it is troublesome to discharge the soil in the supply hopper after the work is completed.

The discharge dial 57 may be attached so that either the drive roller 31 or the passive roller 32 can be rotated by a manual operation, and for example, the rotating shaft 43 of the passive roller 32 or the bush 35 of the drive roller 31. The drive roller 31 may be attached to the horizontal shaft 3 by fixing the gear to the gear and engaging the gear to be rotated by the discharge dial 57.
If it is attached to the fixed structure 6, the discharge dial 57 can be attached to one end of the horizontal shaft 36.

[0013]

[Operation] Next, the operation will be described. When the pot sheet 1 is placed on the support rail 11 of the transfer table 10 as shown in FIG.
The transfer member 16 provided on the endless chain 15 is the pot sheet 1
The pot sheet 1 is engaged with the engaging projection 8 through the gap 7 and moves in synchronization with the seed feeding of the seed feeding device.
When the pot sheet 1 approaches the floor soil supplying device 25, the engaging ratchet wheel 5 located in front of the feeding portion 60 of the soil feeding belt 30.
0 below, the engaging ratchet wheel 50 engages with the engaging hole 9 of the pot sheet 1 and is rotated by the movement of the pot sheet 1,
The rotation of the engaging claw wheel 50 is transmitted to the lower horizontal shaft 47, the gear 48, the chain 49, and the gear 46 to rotate the drive roller 31, and the drive roller 31 rotates the soil feeding belt 30 and the inside of the supply hopper 26. The soil is dropped from the feeding unit 60, and the floor soil falling from above is supplied to each pot 2 of the pot sheet 1.

Then, the work is completed, and the supply hopper 2
Although dirt remains in the inside of 6, the discharge dial 57 is exposed when the mounting screw 59 is removed, and when the discharge dial 57 is rotated, the discharge dial 57 rotates the rotary shaft 43, and the rotary shaft 43 is passive. The roller 32 is rotated to rotate the soil feeding belt 3
Since 0 is rotated, the soil in the supply hopper 26 is easily discharged. In this case, the discharge dial 57 is the rotary shaft 4
Since it is fixed to 3, the configuration is simple. Further, since the discharge dial 57 is fixed to the rotary shaft 43, the discharge dial 57 is rotated during the soil supplying work, but the discharge dial 57 is surrounded by the cover 58, which is safe. Since the discharge dial 57 is fixedly attached to the rotary shaft 43 of the passive roller 32, the other drive roller 31 can be rotatably mounted on the horizontal shaft 36 mounted on the frame 37. In addition to smoothing the rotation of the frame, the horizontal shaft 36 can be used for determining the width of the frame 37.

[0015]

According to the present invention, the upper portion of the pot 2 is vertically and horizontally connected by the connecting portion 6 and the pot sheet 1 in which the engaging holes 9 are formed at predetermined intervals on the left and right sides, and the transfer table for horizontally transferring the pot sheet 1 are provided. 10 and a floor soil supply device 25 provided above the transfer table 10 and having an upper supply hopper 26 and an earth feeding belt 30 wound around a driving roller 31 and a passive roller 32 below the supply hopper 26. In the configuration in which the driving roller 31 is rotated by the engaging claw wheel 50 that rotates by engaging with the engaging hole 9 of the pot sheet 1 being transferred, the driving roller 31 or the passive roller 32 is A discharge dial 57 that can be manually rotated by rotating one of the rollers
Since the soil supplying device for the pot sheet is attached, when the discharging dial 57 is rotated, the driving roller 31 or the passive roller 32 is rotated, and the roller rotates the soil feeding belt 30, so that the supplying hopper 26
The soil inside can be easily discharged, and workability and operability are improved. Further, according to the present invention, the drive roller 31 is rotatably attached to a horizontal shaft 36 fixed to a frame 37, and a discharge dial 57 is attached to a rotary shaft 43 of the passive roller 32 to provide a pot sheet soil supply device. Since the discharging dial 57 is directly fixed to the rotary shaft 43, the number of parts is small, the structure is simple, the cost is not increased, and the discharging dial 57 can be retrofitted to the already sold soil supplying device. Further, since the discharge dial 57 is fixedly attached to the rotary shaft 43 of the passive roller 32, the other drive roller 31 can be rotatably mounted on the horizontal shaft 36 mounted on the frame 37. Fifty
In addition to smoothing the rotation from the horizontal axis, the horizontal axis 36 can be used for determining the width of the frame 37. Further, the present invention is
Since a pot sheet soil supply device is provided on the outside of the discharge dial 57 with a cover 58 surrounding the discharge dial 57, the discharge dial 57 is directly attached to the rotary shaft of the drive roller 31 or the passive roller 32. However, it is possible to prevent contact with the discharge dial 57 during the soil supply work and ensure safety.
