This pretreatment device is provided with a working unit 1 and a working unit 1 for supplying a mother stock of a strawberries seedling G grown from a seed stock.
From the cutting part 2 which cuts the end of the stem tip and the end part of the root part while sandwiching and transporting the strawberries seedling G, the mother plant of the strawberries seedling G is flattened and deformed and separated into small plantlets for planting. It has a stock splitting section 3 and a transport section (transport mechanism) 4 for sandwiching and transporting the split strawberries and seedlings G, and a soil removing section 51 is provided in front of the working section 1 and boxed below the transport section 4. A part (boxing mechanism) 52 is provided.

The pretreatment device comprises an L-shaped machine body 53 in a front view, which is formed by combining angle materials and plate materials, and has casters (movable wheels) 54 and stationary position stoppers 55 at the bottom. Have. Reference numerals 5a and 5b denote a pair of wide endless rotating belts that are arranged opposite to each other, are driven by power from a motor (driving device) M, and are substantially lateral from the working unit 1 to the cutting unit 2, and pass through the stock dividing unit 3. It is hung over the transport unit 4 in a substantially vertical direction, and is configured to transport the strawberries seedling G placed on the lower endless rotary belt 5a while being sandwiched by the upper endless rotary belt 5b.

In FIG. 1, the lower endless rotating belt 5a of the working unit 1 is a tension pulley 5 from the right end (starting end) side.
6a is slightly inclined to an intermediate position where it is located (horizontal may be used), the strawberries seedling G can be placed on the upper right side, and the upper endless rotation belt 5b is the lower endless rotation belt 5a.
Has a right end (starting end) closer to the cutting portion 2 than the right end thereof, and is inclined downward from the right end to an intermediate position where the tension pulley 56b is located, and the upper endless rotating belt 5b rotates from the conveying starting end opposite to it. The interval is gradually narrowed toward the lower side in the moving direction, and the strawberries and seedlings G are easily pinched.

Further, the endless rotating belts 5a and 5b are inclined in the belt width direction as shown in FIG. 3, and the strawberries seedling G is placed in an inclined posture so that the root side is on the lower side and the stem side is on the upper side. And then transported in that position. Each of the endless rotating belts 5
Sensors S1 and S2 for detecting oversized strawberries are placed on the back side of the sandwiching side of the strawberries seeds G of a and 5b.
As for 1 and S2, a contact type or non-contact type switch is used.

The endless rotating belts 5a and 5b are moved in the facing outward direction by sandwiching the strawberries and seedlings G, and the movements are detected by the sensors S1 and S2.

The claw driving means 65 of the stock splitting unit 3 can connect and disconnect the power from the motor M by the electromagnetic clutch 66, and when the sensor S3 detects the carry-in of the strawberries seedling G, the electromagnetic clutch 66 is operated. The holding claw 15 and the stock split claw 16 are driven.

This is because if the claws 15 and 16 are constantly driven even when the strawberries seedlings G are not carried into the stocking section 3, the power loss is large and the stock splitting timing is suddenly when the strawberries seedlings G are suddenly carried in. There is a case where they do not match, and in order to prevent these, the claws 15 and 16 are driven only when necessary. The endless rotation bands 10a and 10b are constantly driven.
