Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transplanting machine, and more specifically to a transplanting machine with an improved seedling feeding device that sequentially supplies soiled seedlings from a seedling storage section to a planting section.

When seedlings, such as onions, are mechanically planted using a transplanter, there are cases where the seedlings are planted with washed roots and seedlings with top dressings, and in the former case, rooting is poor and the seedlings Since the cultivation itself is difficult, the seedlings are grown in a greenhouse etc. in an orderly manner so that they can be separated one by one, and the grown bacteria group is separated into individual seedlings with soil or rows of seedlings with soil and transplanted. It is preferable to use the latter type of seedlings, in which the seedlings are supplied to a machine and then planted one by one.

However, for seedlings of the latter type, which grow as dense clusters in an orderly manner and can be separated one by one, it is possible to grow seedlings in a seedling container such as a paper tube, or in the mixed soil of a seedling box. It is common to have a notch cut out.

When using seedlings with soil, there may or may not be seedlings in the block of soil, so it is important to screen out the presence or absence of seedlings so that planting may lead to missing plants. In addition, because the seedlings are grown in the ground, it is important to properly hold or maintain their posture during the feeding process.

Is the present invention a transplant device that solves these problems? This is what we intend to provide.

Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings.

shall be established.

As is clear from the above explanation, in the specific example shown in FIGS. The pair of conveyor bodies 31 that constitute the 11 @ next stem F2 are held in a hanging manner and sent to the seedling feeding guide means 42. At this time, if the stem F2 is missing or if the stem is defective, the conveyor body 31
The seedlings are not clamped by the block F1, but even if they are clamped, they fall under the weight of the block F1, and only normal seedlings are supplied to the seedling feeding means 42,
The planting is sequentially supplied to the disk 4 while correcting the posture and arranging the plants using the guide plate 47.

The present invention is carried out as described above, by placing block seedlings in a seedling raising container or other container on a seedling storage section, pushing them onto a seedling conveyor or transferring them, and placing them vertically or horizontally. During the process of feeding the seedlings, the presence or absence of missing plants is selected, and the posture is corrected to supply the planting disks to the device, so even if block seedlings are used here, they will grow well. It is of great benefit as it allows for smooth and appropriate supply of seedlings and transplantation.

In particular, a sorting means consisting of a conveyor that clamps the stems of the seedlings is provided above and in front of the extrusion means for pushing out a row of seedlings on the seedling storage section, and a seedling feeding guide having a conveying surface on the same horizontal plane as the seedling storage section. The means is provided to wrap around the forward end of the sorting means at the lower front side thereof, and the seedling storage section is formed with a seedling falling section between the seedling feeding guide means, so that defective seedlings that are not clamped by the sorting means fall under their own weight. The present invention is excellent in that it allows only normal seedlings to be delivered to the guiding means, thereby ensuring that the seedlings are planted without any defects.
