Reference numeral 51 is a compression roller provided on the lower side of the floor soil supplying device 47.

(Operation) Next, the operation will be described.

The supply section 9 of the transfer table 1 is open at the rear, so that the storage box 2 with the pot sheet 4 placed on the upper surface is successively polymerized and supplied. This supply work is easy because it has an open rear part. In the supplied storage box 2, the rear part of the storage box 2 at the lowermost stage rides on the support roller 33, and the front part rides on the fast-forward roller 14 and is in the forward tilted state (FIG. 5). When the motor 46 is energized in this state, the transmission shaft 19 → sprocket 20 → chain 21 → sprocket 18 → rotating shaft 12 → sprocket 16 → chain 17
→ The rotating shafts 11 and 12 are rotated by conduction with the sprocket 15,
Since the fast-forwarding rollers 14, 14 attached to 12 rotate, the storage box 2 generally moves to the front side as shown by the dotted line position, and the rear part of the storage box 2 at the lowermost stage is separated from the support roller 33 and becomes horizontal. , The lowermost storage box 2 comes to ride on the front and rear fast-forwarding rollers 14, 14, and the fast-forwarding rollers 14, 14 are rotating, so the lowermost storage box 2 is
Sent forward.

Therefore, since the gap 32 through which the lowermost storage box 2 passes is formed below the lower portion 31 of the front wall 29, the gap 3 is formed.
Although it is transferred to the lower side after passing through 2, the storage box 2 in the second and higher stages is stopped because the front end portion 37 of the pot sheet 4 is in contact with the inner surface of the front wall 29.

When the lowermost storage box 2 passes through the gap 32, the high end of the second storage box 2 is above the support roller 33, and the front end 30 moves downward to move to the bottom. Since the pot sheet 4 on the storage box 2 is pressed down, even the pot sheet 4 which is warped and floated up can be pressed down and passed through the gap 32, so that it can be passed without being caught on the wall.

When the pot sheet 4 and the storage box 2 are transferred to the lower side in this way, the soil is supplied by the soil cover supply device 39, and the seeding device 4
The seeds are sown according to No. 3, and the soil is supplied by the soil supply device 47, so that the seeding is completed smoothly.

(Effect) Although the known surrounding wall is a box type whose rear surface can be opened and closed, it is difficult to supply the storage box from above to the supply section. It is unnecessary. Further, when only the lowermost storage box is sent out by the rapid feed belt having the protrusion, the front side may be lifted and caught. In particular, as in the present application, in the case where the pot sheet is placed on the top, the pot sheet is often warped, and the front side thereof floats up and can be caught in the gap, so that the storage box at the front is not removed each time. must not.

However, according to the present invention, the front portion of the device for supplying the soil / seed or the like to the position above the transfer table 1 for laterally feeding the storage box 2 in the horizontal state in which the pot sheet 4 is placed and fitted on the upper surface side, or one of the parts. And a supply part 9 capable of accommodating the storage box 2 in a stacked state in a plurality of stages is provided at the start end part 8 of the transfer table 1. The supply part 9 has a rear part opened and a front part and a side part. A surrounding wall 27 that surrounds only a portion, a fast-feed roller 14 that supports and feeds the lower surface of the lowermost storage box 2 of the multiple-stage overlapped storage boxes 2 and feeds forward, and a lower stage at a position higher than the fast-forward roller 14. The support roller 33 that supports the rear part of the storage box 2 in the second stage when the storage box 2 is sent forward, and the storage box 2 in the bottom stage
Since the storage box supply device of the pot sheet seeding device is configured to have the gap 32 provided at the lower portion of the surrounding wall 27 through which only the surrounding wall 27 passes, only the front side and the side part of the surrounding wall 27 are open. Therefore, the structure is simple, the cost is low, and the storage box 2 is easily supplied. Also, the supply unit 9
Among the storage boxes 2 supplied by superimposing a plurality of stages, a fast-forwarding roller 14 that supports the lower surface of the lowermost storage box 2 and when the lowermost storage box 2 is fed forward at a position higher than the fast-forwarding roller 14 2 Since it has a support roller 33 that supports the rear lower surface of the storage box 2 of the second stage, when the storage box 2 of the lowermost stage is fed, press it from above with the front end of the storage box 2 of the second or higher stage. Since it is sent, even the pot sheet 4 that is curving up and floating is suppressed by the floating and the gap 3
It has the characteristic that it can pass through 2.
