Description

Description: TECHNICAL FIELD The present invention relates to a seedling transplanter for transplanting crop seedlings such as straw grass, and more specifically, to a crop seedling placed on a seedling stand on a seedling take-out port. The present invention relates to a seedling transplanter having a planting mechanism that is configured to send the seedlings to each of the plants and picks up the seedlings one by one from the seedling take-out port.

[Conventional technology]

In the above-mentioned seedling transplanter, conventionally, there is a structure in which a plate-shaped support member that receives and supports the upper part of the stem portion of the placed seedling is provided above the seedling take-out port of the seedling stand (for example, the present application. (See Japanese Patent Application No. 1-321639).

[Problems to be Solved by the Invention]

The above-mentioned conventional structure is designed to receive and support the standing seedlings and not to hinder the operation of the seedlings when the seedlings are taken out.

However, crop seedlings such as straw grass have relatively hard stems and roots, and the seedling stand moves back and forth with a constant stroke. The top seedlings tend to have unstable lateral orientation. When the seedling removal action is performed in such a state of falling sideways, the seedling holder may be mistakenly bent further in the direction of falling sideways due to the seedling holder, which may cause damage, and there is a drawback that smooth planting cannot be performed. .

The present invention aims to solve the above-mentioned problems.

[Means for solving the problem]

The characteristic configuration of the present invention is, in the seedling transplanting machine described at the beginning, above the vicinity of the seedling take-out port of the seedling placing table, in conjunction with the planting operation, the lower end is retracted to a position where it acts on the root of the seedling and above. The point is that a rake-shaped partitioning tool that can move up and down over the above-mentioned position is provided.

[Work]

The leading seedling on the seedling take-out port side is supported by a rake-shaped partitioning tool that is long in the vertical direction, and the horizontal posture is stabilized. Moreover, since the partitioning tool moves up and down, it does not interfere with the seedling removal action of the planting mechanism by retreating up and down.
When moving downward, its lower end acts on the root of the seedling,
The lateral separation of the seedling-holding seedlings by the planting mechanism is performed smoothly.

〔The invention's effect〕

Therefore, according to the present invention, by adding a member having a rational structure, the lateral posture of the leading seedling is stabilized, the risk of seedling damage is reduced, and the number of seedlings of the planting plant is stabilized, resulting in It has become possible to provide a plant that can prevent the occurrence of stockouts and can perform a smooth planting operation.

〔Example〕

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

FIG. 1 shows a straw plant seedling transplanter according to the present invention. This seedling transplanter is connected to a traveling machine body (not shown) via a link mechanism (1) so as to be able to move up and down, and is reciprocally driven at a constant stroke with respect to a frame-equipped planting transmission case (2). After that, the seedling stand (3) in a downwardly inclined posture, the strawberries seedlings (a) placed on the seedling stand (3) from the seedling outlet (5) provided at the lower end of the seedling stand (3) [crop seedling [Example of planting] and planting the plants one by one and planting the seedlings from the top seedlings sent to near the seedling take-out port (5) prior to the seedling taking-out operation of the planting mechanism (4) ( 3) A seedling holder (6) for holding the strawberries seedlings (a) placed thereon and forcibly moving them to the seedling take-out port (5) is provided.

An endless belt type vertical feed device (8) with a locking projection (7) over the entire width of the strip is provided at a position on the seedling take-out port (5) side of the seedling stand (3) to take out the placed seedling (a). It is arranged for delivery towards the mouth (5). In addition, a partition wall (9) extending substantially over the entire area is erected at the center of the seedling placement surface (3a) in the left-right direction, and a slide plate (which pushes the uppermost rear end of the seedling placement (a) downwards ( 10) is provided. This slide plate (1
As shown in FIG. 4, the slit (11) formed in the central portion of (0) engages with the partition wall (9), and the upper engaging portions (12) and (12) have support rods (). 13) and 13) are slidably engaged. The engaging portions (12), (12) are locking pieces (14), (14) for locking the support rods (13), (13) to the outer side, and both locking pieces (14). ), (14), and a retaining device (15) extending above the retaining device (15). The retaining device (15) is rotatably attached in a loosened state by tightening it with a central thumbscrew (16) to prevent retaining. The slide plate (10) can be easily removed by loosening and rotating the tool (15).

The seedling holder (6) is a support arm (18) pivotally connected to the planted transmission case (2) via a pair of front and rear links (17a), (17b), and this support arm (18). It consists of a seedling holding claw (19) that can swing relative to, and is urged to move forward by a coil spring (20).
The cam mechanism (21) moves back and forth to perform the above-mentioned seedling holding action prior to the operation of the planting mechanism (4).

Then, the seedling take-out port (5) of the seedling stand (3)
A rake-shaped partitioning tool (upwardly and downwardly movably) between a position where the lower end portion acts on the root portion of the seedling (a) and a position retracted upward in association with the operation of the seedling holding tool (6). 23) is provided. More specifically, as shown in FIGS. 2 and 3,
Each strip partition (24) at the lower end of the seedling stand (3),
The partitioning tool (23) is interposed between the fixed support shaft plates (25) and (25) standing upright from the (24) so as to be vertically movable relative to each other, and its upper end portion is provided with a pair of left and right swing arms (26). ), (26) and guide pins (28), (2) which are supported by the fixed support plates (25), (25) and engage with the lower vertical slots (27), (27).
8) is provided. In addition, a push-pull rod (32) is provided between the swing arm (30) and the upper part of the partitioning tool (23), which are interlockingly connected to the seedling holding tool (6) driving link (17a) through a wire (29). It is interlockingly connected through.

When the seedling holder (6) is in the rearward retracted position, the swing arm (30) is pulled by the pulling operation of the wire (29) to cause the spring (31).
The partitioning tool (23) retreats upward by swinging backwards against. Then, as the seedling holder (6) moves forward toward the seedling take-out opening (5), the pulling force of the wire (29) is weakened and the swing arm (30) is urged by the spring (31). The divider (23) is configured to swing forward and move downward. Then, at the time of this downward movement, the lower end of the sharply formed partitioning tool (23) acts on the root of the seedling (a), and the seedling to be planted and the seedling on the side thereof can be reliably separated. It is configured as follows. The partitioning tool (23) is formed in a plate shape along the front-rear direction, and is configured to effectively prevent the seedling (a) from falling sideways.

It should be noted that reference numerals are added to the claims for convenience of the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
