Abstract

PURPOSE:To suppress falling down of seedling, etc., by installing a transplanting mechanism cutting out and planting seedlings in receiving parts sent out to a seedling take-out port. CONSTITUTION:A transplanting mechanism 5 pivoted to both side faces of a transplanting case 4 is installed in the subject seedling transplanter. Seedlings for planting having a large stock diameter laid on receiving parts d are sent to a seedling take-out port b by transferring of movable frames B in each cutting out and planting by the seedling transplanting mechanism 5, in turn. The seedling transplanting mechanism 5 performs cutting out of seedlings having a fixed stock diameter to be planted from seedlings for planting having a large stock diameter, keeping and planting. Therefore, the seedlings readily stand by themselves even in a longitudinal attitude making root part to bottom or falling down of only foliage part is not happened as the stock diameter of the seedlings laid on the receiving part d is large.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly involves storing washed root seedlings such as rush grass, which have been divided from the parent plant, on a seedling stand in a vertical position with the roots facing down, and then taking out the seedlings one after another. This invention relates to a seedling transplanter that feeds washed seedlings into its mouth and uses a planting mechanism to cut and plant them.

[Conventional technology]

Conventionally, in this type of seedling transplanter, the seedling surface of the seedling stand is formed with a plurality of partition walls to form a vertical seedling storage space, and the parent plant is divided into this storage space to accommodate the diameter of the plant to be planted. Seedlings were stored and arranged in rows, and the seedlings were sent toward the seedling outlet by a vertical feed mechanism that supported the roots and rotated.
(For example, Japanese Patent Application No. 1-23388) [Problems to be Solved by the Invention] In storage spaces arranged in rows like this, partition walls are arranged in parallel at intervals approximately equal to the diameter of the plant, or The diameter of the divided plants varies considerably, partly because it is done artificially.

In this case, the planted seedlings are supported by the partition walls on the left and right sides, but the planted seedlings arranged in rows are only supporting each other in the front and back direction toward the seedling take-out port. When small-diameter seedlings are lined up in a row,
The seedlings that follow or the seedlings in front may fall down laterally, and the fallen seedlings will not receive the planting action of the planting mechanism of the planting mechanism. Furthermore, even if the seedlings do not fall over, the root diameter is larger than the stem diameter, so the stems of the following plants tend to fall between the front plant and the side wall, making it difficult for the seedling planting mechanism to grasp them effectively.
Or, even if they were able to grasp it, there was a problem that the planting posture was poor.

An object of the present invention is to provide a seedling transplanter that can reasonably set the diameter of the seedlings placed in the seedling storage section and suppress the collapse of the seedlings.

[Means to solve the problem]

The characteristic configuration according to the present invention is to form a storage section for storing seedlings for planting with a diameter larger than that of the seedlings to be planted in a vertical position with the roots facing down, and to use this storage section for feeding the seedlings. A drive mechanism is provided for moving a plurality of movable frames formed along a direction toward a seedling take-out port, and a planting mechanism is provided for cutting and planting the seedlings in the storage section fed out to the seedling take-out port. There are certain points, and its effects are as follows.

[For production]

That is, each time the seedling planting mechanism cuts out and plants the large seedlings placed in the storage section, the movable frame sequentially sends them out toward the seedling take-out port. The seedling planting mechanism cuts out and holds seedlings with a diameter to be planted from among the larger diameter seedlings for planting, and plants them.

Therefore, since the seedling placed in the storage section has a large diameter, it can easily stand on its own even in a vertical position with its roots facing down, and only the leaves and stems will not fall over.

〔Effect of the invention〕

As a result, the fall of seedlings or the fall of leaves and stems in the stored state is reduced, and the phenomenon of missing plants is reduced.

Furthermore, even if the parent plant is divided and the divided seedlings are placed on the seedling surface, the work of dividing the parent plant is easier as the number of times of division can be reduced as the diameter of the parent plant increases.

〔Example〕

Next, an example will be described.

A description will be given of a rush seedling planting device (A) that is attached to the rear end of a traveling body (not shown) via an elevating link mechanism (1). As shown in Figure 1, this seedling planting device (A) consists of a seedling platform (2) that moves back and forth horizontally with a constant stroke, and a feed case (2) that receives power from a traveling body (not shown).
3), a planting case (4) that extends rearward from this feed case (3), and a planting mechanism (5) that is pivotally supported on both sides of this planting case (4). We are prepared.

Next, the structure of the seedling stand (2) will be explained.

The seedling mounting table (2) is divided by a partition wall (6) corresponding to the number of planting rows, and a horizontally long seedling mounting frame unit ( 7) are arranged in parallel along the longitudinal feeding direction. As shown in Figure 2, the frame unit (7) is connected to the partition walls (6) of the left and right seedling stands (2), which have a constant width in the front and back, and (6) a frame with a width slightly shorter than the interval. A main body (7A) and connecting arms (7B) that project backward from both lateral ends of the frame main body (7A).
), and there are retaining pins (
7a) is provided protrudingly, and an engagement groove (7a) is provided at the rear end of the connecting arm (7B).
b), and by engaging the engagement groove (7b) with the retaining pin (7a) of the subsequent frame unit (7), each frame unit (7) is linked to form a movable frame (B). do.

When each frame unit (7) is connected, a certain space is formed between the rear surface of the frame body (7A) of the front frame unit, the left and right connecting arms (7B), and the front surface of the frame body (7A) of the succeeding unit. , Seedlings for planting (a) which are divided from the parent plant and have a larger diameter than the seedlings to be planted are stored in this space. This space will be referred to as a storage section (d).

The first frame unit (7) that has conveyed the seedlings for planting to the seedling take-out port (b) is lifted by a dedicated lifting and recovery device (not shown), and the connection with the following frame unit (7) is cut off. to recover.

Next, the seedlings for planting (a) are fed out near the seedling outlet (b).
) to the seedling removal port (b) will be explained. As shown in Figure 1, a planting case (4
) is equipped with a scraping claw (9C) driven by a crank arm (9A) and a swinging arm (9B) on the opposite side of the planting mechanism (5) to remove the seedlings for planting (a). It constitutes a scraping mechanism (9) that acts on and scrapes out the leaf and stem portions. This scraping mechanism (9) does not operate continuously like the planting mechanism (5), but operates intermittently.

Although not shown, a lateral movement mechanism is provided for reciprocating and lateral movement of the seedling platform (2) at a constant stroke, and the lateral movement mechanism is used to move the seedling platform (5) when the planting mechanism (5) scrapes off the seedlings. stop,
Set to intermittent operation mode, which starts moving when scraping is completed.

With the above configuration, a plurality of seedlings for planting (a) having a diameter larger than that of the seedlings to be planted (the parent plant itself, which is divided from the parent plant or not) are lined up side by side in the storage part (d). Place the seedlings on the seedling outlet (b) and move the seedling stand (2) horizontally.
), the seedlings are cut out and planted using the planting mechanism (5). When the seedling platform (2) reaches the end of the horizontal feed movement, the vertical feed mechanism (8) and the scraping mechanism (9) operate, and the seedlings for planting (
A) is pulled out to the seedling take-out port (b), and the seedling platform (2) starts to move laterally.
