The present invention relates to a seedling transplanter for picking and planting seedlings from a seedling box. [0002] 2. Description of the Related Art A method for supplying seedlings is disclosed in Japanese Patent Application Laid-Open No. 5-328806.
Place the seedling box with the seedling box tilted so that the
A plurality of seedling supply units that can be placed in series in the feeding direction
A stage is provided, and the seedling supply units of the upper and lower stages merge with the main supply unit.
And the seedling boxes placed in each seedling supply section are
Set up a seedling supply regulator to stop trying to move to the supply
There was a ginger seedling transplanter. In addition, this conventional machine is regulated
When the state that the movement of the seedling box is stopped by the body is released, the seedling supply
Not only the seedling box that was directly blocked by the body, but also
The subsequent seedling boxes were also moved and supplied. [0003] As described above, the conventional seedlings
The transplanter moves several seedling boxes together from the seedling supply
Since these seedling boxes are supplied to the main supply unit,
The impact when stopping at a predetermined location is large, and
There was a problem that the seedlings in the seedling box could jump out. [0004] Note that mat seedlings are not stored in a seedling box.
In the case of seedlings in the condition, the colliding ends are crushed or
The number of planted seedlings has changed due to collapse,
Problem. [0005] [MEANS FOR SOLVING THE PROBLEMS]
In addition, the following measures were taken. That is, the lower side of the seedling supply direction is
Seedling or seedling box in the seedling supply direction
A plurality of seedling supply units that can be placed in series
The upper and lower stages of the seedling supply section merge with the main supply section.
And the seedlings or seedling boxes placed in each seedling supply section
A seedling supply regulator to stop trying to move to the main supply
Establishment,The movement of seedlings or seedling boxes is prevented by the seedling supply regulator.
When releasedOther seedling supply regulators move seedlings or seedling boxes
At the same time, the seedling supply section
The movement of the seedling or seedling box by the body has been released
ComeSeedlings or seedlings that have been directly prevented from moving by the seedling supply regulator
Only the box is supplied and the subsequent seedling or seedling boxRegulation of supply
When the seedling or seedling box is in a movement-prevented state by the seedling supply regulator,
Seedlings or seedlings that are directly prevented from moving by the seedling supply regulator
Remove restrictions on the supply of seedlings or seedling boxes following the boxFollow-on seedling
A seedling transplanter characterized by providing a supply regulating means. [0006] Therefore, according to the present invention, first, a plurality of
A plurality of seedlings or seedling boxes are connected in series in the seedling supply direction at each seedling supply section
It is fully loaded in a state where it is placed on Seedling supply or seedling box
ofSeedling supply regulators are preventing transfer to the main supply. Yo
Therefore, when the seedling supply regulator releases the movement
The seedlings or seedling boxes in the supply section move to the main supply section and are supplied. This
At the time of the seedlings,
The seedling box moves to the main supply department,Seedlings in other seedling supply regulators
Or, the movement of the seedling box is stopped and the movement of the seedling or seedling box is restricted.
Not controlled and not supplied. Also, the movement prevention state has been released
In a seedling or seedling boxSubsequent seedlings or seedling boxes should be
The movement to the main supply unit is restricted by the above, and the supply is not performed. Preceding
Seedling or seedling box passes through the regulatory action section of the seedling supply regulator
After moving to the main supply section, the seedling supply control body
Supply control by means of subsequent seedling supply control means
Is also canceled. Here, the supply is regulated by the subsequent seedling supply regulation means.
Subsequent seedlings or seedling boxes that have been moved toward the main supply
However, the transfer to the main supply section was prevented by the seedling supply regulator.
It is. [0007] Therefore, a plurality of seedlings placed in series can be supplied.
Seedlings or seedling boxes are moved to the main supply unit one by one and supplied.
The seedling box stops at a predetermined point in the main supply section
The impact at the time can be kept small. Therefore,
The pressure of the seedling that was generated by the large impact
Prevent shrinkage and damage, or the escape of seedlings from the seedling box
To stabilize the number of seedlings planted and to prevent the occurrence of missing plantings
