Description

[Detailed description of the invention] This invention is a seedling feeding device in a seedling transplanter, which enables smooth transfer of seedlings from the seedling stand to the seedling holder, and prevents deformation of the lower end of the seedling stand. The purpose is to

On the bottom of the seedling tray of the seedling transplanter, there are many pine-shaped seedlings placed on the bottom of the seedling tray to prevent them from sliding sideways in the left and right direction when the pine-shaped seedlings placed on this table are sent toward the seedling tray. A protrusion consisting of a rim or keel is provided. However, with conventional devices, when the tops of the ridges are aligned with the receiving surface of the seedling holder, the lower ends of soft, pine-like seedlings are lower than the tops of the ridges, so there are only a few seedlings. When this occurs, the seedlings may fall over due to the influence of the upper edge of the bottom side of the receiving surface of the seedling holder, or the joints of the seedlings may not stick together. On the other hand, if the bottom of the seedling stand and the receiving surface of the seedling holder are aligned, the ridges will not dig into the bottom of hard, pine-like seedlings with little moisture, so when passing them on, the tops of the ridges will need to be aligned. The seedlings started falling onto the receiving surface, and when there were only a few seedlings left, they sometimes fell over.

In addition, the lower edge of the seedling stand becomes deformed over time, and as a result, seedlings may not be transferred smoothly from the seedling stand to the seedling holder.

This invention overcomes these conventional deficiencies.

Next, the device for feeding out seedlings in the seedling transplanter with this invention will be explained based on the drawings. 1 is a seedling mounting stand, which has a pair of side walls 1a, 1a on the left and right.
A pine-shaped seedling with a size of cm x 60 cm is placed on the bottom surface 1b, and the seedling is placed diagonally so that it can be rolled out in the longitudinal direction. Reference numeral 2 denotes a seedling holder, which is fixed to the body with its L-shaped bottom receiving surface 2a and vertical receiving surface 2b facing upward. And seedling stand 1
is provided so that its lower edge 1f approaches in parallel with the bottom upper edge 2f of the bottom side receiving surface 2a of the seedling holder 2 and moves from side to side, and on the bottom surface 1b there is a holder that faces toward the seedling holder 2. A large number of parallel protrusions 1c, 1c... are formed, and the lower end of the bottom surface 1b is thickened so as to bulge toward the top ends 1d, 1d... of the protrusions 1c, 1c... as it approaches the lower edge 1f. It is set in.

In the figure, 2c is a seedling outlet, 3 is a feeding wheel, 4 is a liner, 5 is a reinforcing metal, 6 is a guide piece, and 7 is a seedling planting claw.

Since this feeding device is configured as described above, the lower surface and end surface of the lower end of the pine-shaped seedling are in contact with the bottom side receiving surface 2a and the vertical side receiving surface 2b of the seedling holder 2, and the upper side of the pine-shaped seedling is is placed on the bottom surface 1b of the seedling stand 1,
When the seedling platform 1 is moved from side to side, its lower end portion slides on the seedling holder 2 and moves from side to side. Here, the seedling planting claw 7 is descending through the seedling removal port 2c, so
The seedlings above the seedling removal port 2c are scraped off by the seedling claws 7. In this way, when the lower end of the pine-shaped seedling is scraped off, the feeding wheel 3 is activated and the pine-shaped seedling is fed downward until the end surface contacts the vertical receiving surface 2b. By repeating this process, the pine-shaped seedlings are eventually cut off from the right end to the left end and from the left end to the right end while being intermittently drawn downward.

When the number of one seedling runs low, the next seedling is added on top of the pine-shaped seedling. If the seedlings are too soft due to overcontaining, the protrusions 1c, 1c, etc. will dig deep and the bottom surface of the seedlings will reach the floor 1a, but the bottom end of the seedlings will fall on the seedling stand 1 and the bottom of the seedlings will fall. When trying to reach the edge 1f, the bottom surface 1b at the lower end
Since the seedlings are close to the top ends 1d, 1d... of c..., the lower surface of the seedling is lifted and smoothly transferred onto the bottom receiving surface 2a.

In short, this invention consists of an inclined seedling platform 1 on which pine-shaped seedlings are placed, and an L-shaped bottom receiving surface 2.
a and a vertical side receiving surface 2b, and the lower edge 1f of the seedling stand 1 is the bottom upper edge 2f of the seedling holder 2.
The bottom surface 1b of the seedling stand 1 is provided with a large number of protrusions 1c, 1c, . . . facing the seedling holder 2, and this bottom surface 1b
As the lower end approaches the lower edge 1f, the protrusions 1c and 1
Since this is a seedling feeding device in a seedling transplanter characterized by being thickly provided so as to bulge toward the apex 1d, 1d... of c..., protrusions 1c, 1c for preventing side slipping. The lower surface of the pine-shaped seedling that has bitten into the lower surface is pushed up at the lower edge 1f of the bottom surface 1b, and the lower end of the seedling holder 2
It has the effect of smoothly moving on the bottom receiving surface 2a of the
In addition, the seedling stand 1 has a lower edge 1f of the bottom surface 1b that is thicker than the rest, so it can withstand long-term use without deformation.
