Description

[Detailed Description of the Invention] [Industrial Application Field J] The present invention is configured to send crop seedlings placed on a seedling stand toward a seedling take-out port, and take out the seedlings 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. 4811.4, a seedling holder is used to divide the divided strawberry seedlings into sections of a considerable amount and hold them in an upright position. There were some configurations in which there were multiple locations.

[Problem to be solved by the invention]

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 required a large-scale drive structure, making it difficult to implement in practice.

An object of the present invention is to provide a seedling transplanter that eliminates the above-mentioned drawbacks and that can reliably separate each crop seedling to be planted with a simple structure and reduce variations in the number of planted crops. It is in the point of doing.

[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 up and down in conjunction with the operation of the planting mechanism to move the roots of the seedlings above the seedling take-out port in the vicinity of the seedling take-out port. A rake-like partition device is provided to push the seedlings out, and a guide in the form of a deep nip is provided between each partition device, which is located above the area where the planting mechanism takes out the seedlings and aligns the area above the roots of the seedlings. The point is that an alignment tool having a section is provided.

[For production]

At the lower end of the seedling stand, the roots of the first seedling to be planted by the planting mechanism are pushed out toward the partition or the area where the planting mechanism acts, so it is certain that the seedling is taken out by the planting mechanism. The more you go, the less you will get. Furthermore, when the partitioning tool is moved upward, the upper part of the roots of the seedlings at the tip in the feeding direction is stopped and guided by the guide part of the alignment tool placed between the partitioning tools, but this guide part is shaped like a deep pinch. Therefore, each plant will be separated and guided in the innermost part. As a result, the number of target bacteria to be planted by the planting mechanism remains constant.

〔Effect of the invention〕

Therefore, according to the present invention, the bacteria to be planted can be reliably isolated, and the upright posture of the seedlings can be maintained well, and
This reduces variation in the number of seedlings planted and maintains a smooth planting operation with less risk of damage due to missing plants or tearing of seedlings.

〔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 mechanism for planting rice seedlings with a well-known structure, and uses a crank swinging mechanism (11) to move the tip of the rice seedling along a substantially elliptical trajectory while planting one seedling. It is equipped with a planting nail (lO) that is cut out and planted in the 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 partition (12) is provided which can move up and down between the position and the upper position where it moves upward in the sending direction of the seedlings to separate the stems of the seedlings.

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, and this horizontal frame 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 driven dynamically.

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 the rod (24) in one direction, and an arm (25) that swings the rod (24) in one direction, and
6) is interlocked with an arm (26) provided so as to be swingable through a push-pull rod 1'' (27).

The horizontal frame portion (13) for each strip has left and right bins (2
8), (28) on the vertical frame (15) on the seedling surface (
It is engaged with a guide slot (29) formed in a direction substantially perpendicular to 4a) and supported so as to be movable up and down. The swing arm (17) is positioned in the guide elongated hole ( 29), and when the swinging arm (17) 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 partitioning tool (tool 2) moves upward in the direction of sending out the seedlings.

As shown in FIG.
0), increase the distance from 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 as to fit within the tip trajectory of the planting claw (10) 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. The root part of the seedlings can be smoothly guided into the divided 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 arms (33) are pivotally supported on both the 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 to the drive swing arm (17) by a rod (36). In this way, the guide part (31
), the number of target bacteria to be planted will always be maintained constant, and the variation in the number of plants will be small.
It moves up and down in the opposite direction to 12) to prevent the seedlings from being dragged when the partition tool (12) is moved upward, thereby ensuring the separating action.

[Another example]

The alignment tool (32) may be provided in a fixed position instead of moving up and down in synchronization with the partition tool (12).
