Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is configured so that crop seedlings placed on a seedling stand are sent out toward a seedling take-out port, and the seedlings are taken out one by one from the seedling take-out port. This invention relates to a seedling transplanter equipped with a planting mechanism for planting seeds.

[Conventional technology]

In the above-mentioned seedling transplanting machine, conventionally, for example, JP-A-1-1
As disclosed in Publication No. 48114, a seedling holder is used to divide the divided strawberry seedlings into large sections and hold them in an upright position. Some were configured to have multiple locations.

[Invention or problem to be solved]

The conventional structure described above uses the existing mechanism for planting rice seedlings that are relatively tall and have hard stems, making it possible to plant rice seedlings with fewer mistakes. This is what I did.

However, when using the above conventional structure, the seedling holder is required for each row of seedlings placed on the seedling stand, and during planting, the used seedling holder is removed from the seedling stand. This requires a large-scale drive structure, making it difficult to implement in practice.

The purpose of the present invention is to eliminate the above-mentioned disadvantages, to ensure separation of crop seedlings such as rush seedlings into each planting row with a simple structure, and to reduce the risk of occurrence of missing plants and damaged seedlings. To provide a seedling transplanter capable of improving the standing posture of seedlings.

[Means to solve the problem]

A characteristic configuration of the present invention is that, in the seedling transplanting machine described at the beginning, the seedling platform is moved upward near the seedling take-out opening in conjunction with the operation of the planting mechanism, and moved downward in the seedling sending direction. The lower end acts on the roots of the seedlings and pushes them out to the seedling take-out port, and the upper position moves toward the upper side in the feeding direction of the seedlings to separate the stems of the seedlings. The reason is that it has a rake-like partition.

[For production]

On the lower end side of the seedling stand, the seedling root is pushed out toward the lower side of the partitioning device in the direction of seedling delivery, that is, toward the area where the planting device takes out the first seedling to be planted by the planting mechanism. Seedlings can be reliably removed by the planting mechanism,
There will be less leftovers. Further, when moving upward, it moves toward the upper side in the direction of sending out the seedlings, so at that time, the seedlings can be effectively separated by combing the stems of the seedlings. Since such vertical movement is repeated, separation and extrusion of the seedlings can be continued smoothly.

〔Effect of the invention〕

Therefore, according to the present invention, by providing a partition with a simple structure, the seedlings can be held in a good posture, and the separation and removal of the seedlings can be performed smoothly, thereby preventing the occurrence of missing plants or damaged seedlings. This makes it possible to continue planting operations with less risk of damage. Moreover, since the partitioning tool is provided at a position close to the planting mechanism, there is an advantage that the drive system can be constructed relatively easily by using the existing drive structure of the planting mechanism.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 shows a strawberry seedling transplanter according to the present invention. This seedling transplanter has a link mechanism (not shown) at the rear of the traveling body.
The seedling planting device (2) is connected to a seedling planting device (2) that can be raised and lowered via a frame. It is constructed by attaching a seedling stand (4) that moves back and forth and a planting mechanism (5) that is fixed in position.

Block-shaped strawberry seedlings grown from the mother plant and with the old parts removed are placed and supported in an upright position in each row separated by a partition wall (6) on a seedling mounting table (4). (4a)

) to be cut out and planted in the field.

The planting mechanism (5) uses a well-known mechanism for planting rice seedlings, and uses a crank swinging mechanism (11) to cut out seedlings one by one while the tip thereof traces a substantially elliptical trajectory. The plant is provided with planting nails (10) for planting in a field.

and the seedling outlet (9) of the seedling stand (4).
Near the upper side, in conjunction with the operation of the planting mechanism (5), a lower part that moves downward in the seedling sending direction and acts on the lower end or the root of the seedling to push it out to the seedling take-out port (9). A rake-shaped partitioning tool (12) is provided which is movable up and down between the upper position and the upper position where the stem part of the seedling is separated by moving upward in the feeding direction of the seedling.

To be more specific, as shown in FIGS. 1 and 2, the partitions (12) are integrally fixed to the horizontal frame portions (13) located on the upper side of each strip. Part (1
3) via the left and right arm parts (14), (14),
A swing arm (
17). The rotation shaft (16) extends over the entire fruit, and is powered from the planting transmission case (3) at the outer left and right sides of the seedling stand (4) and swings within a certain range. It is configured to be dynamically driven.

A drive cam (19) is provided on the transmission shaft (18) on the front side inside the planted transmission case (3), and a driven shaft (20) supported near this transmission shaft (18) in a state that projects outward from the case. A cam follower (21) that comes into contact with the drive cam (19) once per rotation is provided, and a return spring ( 23
) to return to the standby position. A rod (22a) supported at the other end of the balance arm (22) in a U-shaped holding part (22a) and swingably supported around the horizontal axis on the lower surface side of the horizontal end strip of the seedling stand (4). 24) is engaged so that it can be slid laterally. Further, an arm (25) that swings integrally with the rod (24) and the pivot shaft (1
6) and an arm (26) provided so as to be swingable are interlocked and connected via a push/pull rod (27).

The horizontal frame portion (I3) for each strip has left and right pins (2
8), (28) on the vertical frame (15) on the seedling surface (
It engages with a guide slot (29) formed in a direction substantially perpendicular to 4a) to support vertical movement. The swing arm (17) is positioned in the guide elongated hole ( 29), and when the swinging arm (F) moves toward the lower position, the partition (12) moves downward in the seedling feeding direction and swings. When the arm (17) moves toward the upper position, the partition (12) also moves upward in the direction of sending out the seedlings.

As shown in FIG.
0), increase the distance to the receiving surface (30a) or the upper side,
The lower end side is formed to be small, and the lower end portion of the partition tool (12) in a downwardly moving state is formed to be narrow so that it fits within the tip trajectory of the planting claw (lO) when viewed from the side. Also, among the partitions (12), every other partition,
The upper end of the upper end in the seedling supply direction is formed to protrude in that direction more than the other parts so that the inner action of raising up the seedlings by vertical movement can work effectively.

With this configuration, the relatively hard and easy-to-separate stem portion can be reliably separated by the large protruding upper side of the divider, and the lower end side is narrower. Smoothly dividing the base of the seedlings makes it easier to guide them into the area, reducing the risk of missing plants.

Then, between each of the partitions (12), planting nails (
10) above the point of action for taking out the seedlings,
In addition, an alignment tool (32) having a guide part (31) in the shape of a rear nip for aligning the upper part of the roots of the seedlings is connected to the partition tool (12).
It is arranged so that it moves up and down in synchronization with the up and down movement of. In other words, the support arm (33) is pivotally supported on both left and right sides of the seedling stand (4) so as to be able to swing up and down around the horizontal axis;
A support rod (34) is installed at the swinging end of the vertical frame (33) over the entire width of the rear side of the vertical frame (15), and the alignment tool (32) is attached to this support rod (34). Then, the middle part of the support arm (33) and the partition (12)
The arm (26), which is provided on the opposite side of the drive swing arm (17) and can swing integrally therewith, is pivotally connected by a rod (36). In this way, when the partition (I2) moves upward by moving up and down in the opposite direction to the partition (12),
This is to prevent the seedlings from dragging and ensure separation.
