This conventional seedling delivery device of a transplanter has a second transfer conveyor with a large number of pick-up members arranged in a row interposed between the first transfer conveyor below the seedling box and the planting disk, and 2 Transfer conveyor with 1st
A conveyance path is formed generally perpendicular to the transfer conveyor, and the seedlings on the first transfer conveyor are picked up one by one by the second transfer conveyor, and the seedlings are planted and supplied to the disk.

(Problems to be Solved by the Invention) In the prior art described above, seedlings can be continuously fed out at regular intervals using the pick-up member of the second transfer conveyor, but if the roots of the seedlings are entangled, the pick-up member of the second transfer conveyor There is no means to untangle the roots before reaching the transfer conveyor, and one pick-up member sometimes picks up multiple seedlings, and it is difficult to shake off adhering soil.

(Means for solving the problem) The tree plant 15111 solves the problem of the conventional technology by cutting a selective sieve between the seedling box (6) and the planting mechanism.
In addition to providing a suction and feeding mechanism, seedlings (3) are installed during sorting.
All of these problems can be solved by providing an air blowing mechanism to untangle them.

That is, the specific configuration of the problem-solving means of the present invention is characterized by a seedling feeding device of a transplanter that continuously sends seedlings from a seedling box to a mechanism for planting them at regular intervals. There is a sorting sheave that receives seedlings that are rejected in excess of quantity and transfers them while sorting them, and a sorting sheave that is located below the end of this sorting sieve picks up the seedlings after sorting one by one and transfers them to the mechanism for planting. It has a suction feeding mechanism and an air blowing mechanism that blows air from below to untangle the roots of the seedlings on the sorting sheep.

(Function) The seedlings (8) taken out from the seedling box (6) are transferred by the sorting sheep circle, and the attached soil is removed, and during the transfer, the roots are removed by the air blown up from the air blowing mechanism below. The tangled seedlings are disentangled and clumps are formed.For planting, the clumps of seedlings are supplied to the suction and feeding mechanism (A) in an amount larger than the quantity. , the plants are sent to Mechanism αQ to be sure to be planted one by one.

A seedling feeding device (a seedling feeding device) is disposed between the seedling box (6) and the belt conveyor 0 of the planting mechanism α. This seedling feeding device (a) is suitably supported by the machine frame (5), and power can be transmitted from the gear case (2) to the seedling box (6).
It has a sorting sheep (21) that receives seedlings (8) from the seedlings, a suction roll placed below the terminal end of the sorting sieve guard 1, and an air blowing mechanism placed below the sorting sheep (21). ing.

The suction roll is connected to a vacuum device (24J) attached to the back of the gear case (2) via a hose □□□, and the suction roll (23) and the vacuum device (goods) are connected to the suction feed mechanism. The vacuum device is a proa, and its discharge port is connected to the air blowing mechanism □□□ via a hose □, which serves as a supply source of the blown air.

The seedling box (6) and the sorting sieve 1) are each supported by a swinging arm a'71vjK so as to be swingable in the front-rear direction (seedling transfer direction). A large number of onions and other screens are stored in a pile in the seedling box (6), which are sequentially fed out from the feeding row at the bottom of the seedling box and supplied to the starting end of the sorting sieve.

Sorting Sheep Prevention) is formed into a serrated shape, and its shape and vibration loosen entangled roots between seedlings,
It divides the seedlings one thick at a time, corrects the seedling's posture parallel to the other, and while doing this, removes the attached soil and transports it forward. (361 is a presser plate.

The air blowing mechanism has many air holes that open upward.
The air supplied from the vacuum device is blown upward from below the sorting sheep (21).

This air is intensively blown onto the roots of the seedlings (8) being transported, loosening entangled roots. This air blowing mechanism (2
The unraveling of the roots by 2 is carried out in parallel with that by the screening sieve factor), and a synergistic effect is produced, resulting in more completeness. Note that the air supply source for the air blowing mechanism (2) may be provided separately from the vacuum device ρ4).

The suction roll is driven to rotate in synchronization with the belt conveyor a◆, and a plurality of recesses parallel to the axis are formed at regular intervals on the outer peripheral surface of the suction roll, and each recess (support) has at least one A suction port 31 is formed, and the suction port @31 can communicate with the hose via a suction path.

The suction port (to) of this suction roll (to) is for sorting sheep (
