Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a transplant tube device for use in a transplanter for planting soiled seedlings such as lettuce into ridges.

(Prior Art) This type of transplanter is disclosed in Japanese Patent Publication No. 57-37282 and Japanese Patent Publication No. 57-46322.

The structure of the transplant tube of these transplanters consists of a tube that receives soiled seedlings supplied from a seedling supply mechanism, and a pair of conical or other front and rear divisions that can open and close the lower end of the tube. After the lower part of the transplant tube that receives the seedlings is inserted into the ridge, the lower end sides of the shutters are opened back and forth, pushing the soil in the ridge back and forth to form a recess into which the seedlings fall. Seedlings are dropped into the seedling-dropping recess, and the seedlings are transplanted into the ridges here.

(Problem to be solved by the invention) According to the above structure, since the opening/closing members of the transplant tube move back and forth to each other to form the seedling-dropping recess, the surrounding soil collapses during the process of forming the seedling-dropping recess. There is a great possibility that soil will enter the seedling depression through the gap created between the two opening and closing members. If the surrounding soil invades the seedling depression in this way,
There is a drawback that seedlings with soil that fall into the seedling-dropping recess are not properly accommodated.

Therefore, in view of the above-mentioned problems, the present invention aims to prevent the soil from collapsing into the seedling-dropping recess and to improve the fit of the seedlings.

(Means for solving the problem) The technical means is that the transplant tube 97 containing the seedlings R
is driven by a drive mechanism, and the transplant tube 97 sticks into the furrow N, and at the same time, the lower side is opened in order to push away the soil in the furrow N and form a seedling-dropping recess, and the transplant tube 97 is inserted into the seedling-dropping recess. In the case where seedlings R are dropped and transplanted, the transplant tube 97 closes the tube body 98 having a U-shaped cross section and the open side of the tube body 98, and leaves the lower side freely openable and closable. ,
A flat lid member 100 pivotally supported on the cylinder body 98 side
There is a point consisting of.

(Function) According to the present invention, the transplant tube 97 that received the seedlings R
is lowered, and the lower part of the transplant tube 97 sticks into the ridge N.
After that, in order to open the lower part of the lid member 100,
The lid member 100 is rotated around the pivot 101,
The soil is pushed away by the lower part of the lid member 100 to form a rectangular seedling depression. When forming this seedling-dropping recess, three sides of the peripheral wall of the seedling-dropping recess are kept in shape by the U-shaped cylinder main body 98, and the remaining one side is pushed away by the cover member 100. It is possible to effectively prevent soil from collapsing into the interior. The seedling R falls into this seedling falling recess and is transplanted.

In other words, the seedling R breaks and the limit switch 89
Even if the main switch 137 is turned OFF to stop traveling or planting, the operating piece 135 will not activate the limit switch 136.
Until it is turned off, the motor 31 operates and moves the transplant tube 97 and gas burner 115 to the upper position. This prevents the motor 31 from stopping when the transplant tube 97 and gas burner 115 are in the lower position, and prevents the transplant tube 97 from remaining stuck in the ridge N, and the gas burner 115 from spreading the multi-membrane body Q over a wide range. Accidents such as burning can be prevented.
