Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for separating crop seedling bundles at predetermined positions from tape seedlings formed by attaching a plurality of crop seedling bundles at predetermined intervals in the longitudinal direction of the tape. In addition to providing a separating device to separate the crop seedling bundles, the separating device holds the stem tips of the crop seedling bundles, and the held crop seedling bundles are released from the holding in a vertical position with the roots facing down, and then planted. This invention relates to a tape seedling transplanter equipped with a mechanism.

[Conventional technology]

Conventionally, in this type of tape seedling transplanter,
As disclosed in Publication No. 49062, a bundle of crop seedlings held between two tapes is separated and discharged by a separation device that winds and separates the tapes with separate rolls, and the separated and discharged bundles of crop seedlings are separated on the left and right sides. The plant is clamped by a planting mechanism equipped with a pair of elastic clamping rotors, released from holding in a vertical position with its roots facing down, and then planted.

[Problem to be solved by the invention]

However, in this structure, in which only the stem tip of the crop seedling bundle that is separated from the two tapes and falls naturally is held by the elastic clamping rotating body, the falling posture of the crop seedling bundle is affected by the adhesive force with the tape at the time of separation. As a result, the attitude of the elastic clamping rotor at the holding start position of the crop seedling bundle is not constant, and the desired vertical posture is not achieved at the planting position, resulting in poor planting. Ta.

An object of the present invention is to provide a simple mechanism that can be installed at a rationally selected installation position to allow for successful planting.

[Means to solve the problem]

The characteristic configuration according to the present invention is such that the planting mechanism once receives the root part of the separated crop seedling bundle at a holding start position where the tip of the stem of the separated crop seedling bundle is held in a tilted posture facing forward and backward, and the planting mechanism The device is provided with a catch that allows the root to move downward due to operation, and its effects are as follows.

[For production]

In other words, the bundle of crop seedlings separated by the separation device and released to fall naturally is once maintained in a forward and backward falling posture by holding the roots with the receiver and the tip of the stem with the planting mechanism. .

Then, the planting mechanism holding the stem tip moves, for example, by rotation so as to switch to a planting position with the roots facing down, and releases a bunch of crop seedlings at the planting location.

When the planting mechanism rotates, the roots slip through the retainer due to the elastic deformation force of the stem tip.

[Effects of the Invention] Therefore, by providing a simple catch that only catches the roots, the posture of holding the tip of the stem in the planting mechanism becomes constant, and the planting posture becomes stable, so floating seedlings, etc. Planting defects can be prevented. Furthermore, since the seedlings are caught once, there is less impact on the bundle of crop seedlings than when the seedlings are caught mid-fall, and damage etc. can be suppressed.

Moreover, since the planting mechanism holds the stem tip in a tilted position, it is less likely to disrupt the posture due to drooping of the stem tip, compared to, for example, grasping the stem tip in a vertical position with the roots facing down. This has the effect of making it easier to retain the smaller amount.

〔Example〕

The tape seedling transplanter (1) is once a tape seedling making device (not shown).
The tape seedlings created in step 1 are stored in the seedling storage case (2) in a zigzag fashion with the top and bottom facing each other, and the tape seedlings are fed out from there and the crop seedling bundle (a) is separated from the tape (3) and planted. It is something.

The tape seedlings are a bunch of small crop seedlings (a) that have been manually divided from the mother plant against a single continuous tape (3), with the culm direction running along the width direction of the tape (3). Arranged at a predetermined interval in the longitudinal direction of the tape (3),
This is also formed by sewing it onto the tape (3) using a sewing machine (not shown).

As shown in Fig. 1, the tape seedlings stored in the seedling storage case (2) in a tapered manner are fed out downward via the guide roll (4) at the upper end of the seedling storage case (2), and are fed out through the separating device ( Droop down to 5). At this time, the crop seedling bundle (a) is delivered in a tilted posture along the lateral direction of the machine, and midway through, the crop seedling bundle (a) is turned into a tilted posture facing forward and backward.

The separation device (5) has a 10th-
(6), the 20th loop (75) that unravels and winds up the sewing thread (10), and the crop seedling bundle (a) at the separation point of the crop seedling bundle (a).
a 30th rule (8) that guides the tape (3) from which the ) and consists of the 10th
The first rule (6) and the second tenth rule (7) are equipped with slip devices (11) and (12), respectively, for keeping the winding tension constant.

A planting mechanism (13) is arranged below this separation device (5), and these separation devices (5) and the planting mechanism (
Feed case (14) that supplies driving force to

), soil leveling float (16), etc. are connected to form a tape seedling transplanter.

As shown in FIGS. 1 and 2, the planting mechanism (13)
The transmission case (17) is ejected rearward from the rear surface of the feed case (14), and the transmission case (1
7) Arranged on both sides of the power take-off part at the rear end, it receives the discharge tube from the separation device (5), rotates while holding the stem tip of the crop seedling bundle (a), and discharges it onto the field surface. Left and right elastic clamping rotating bodies (18A).

Here, the left and right elastic clamping rotating bodies (18A), (
18B) is a thick rubber plate, which receives and holds the tip of the stem of the dropped crop seedling bundle (a) when the machine is tilted forward and backward, rotates downward, and rotates downward so that the crop seedling bundle (a) When the crop is in the vertical position, the pushing action of the first small-diameter roll-shaped pushing tool (19) is released, and the crop seedling bundle (a) is released and planted. And these elastic clamping rotating bodies (18A) and (18B)
A receiver (24) is provided to temporarily catch the root of the separated crop seedling bundle (a) at the position where the machine starts holding the separated crop seedling bundle (a), and the separated crop seedling bundle (a) is tilted forward and backward. Once the support is stopped in the posture, the elastic clamping rotating body (18A),
The structure is such that the stem tip holding action in (18B) can be performed as expected.

In the figure, (22) indicates the left and right elastic clamping rotating bodies (18A).
) and (18B) are a pair of left and right rod-shaped guides that guide the rotating crop seedling bundle (a) onto the field surface. A groove cutter (
23) is provided, and the structure is such that a groove is made with this groove-maker (23) and the crop seedling bundle (a) is planted in this groove. In addition, the rear end position of the bottom plate (23A) of this trencher (23) is provided near the swinging fulcrum (X) of the soil leveling flow 1- (16), so that the trencher (23) swings integrally with the soil leveling float (16). (2
3) A structure is adopted that reduces height fluctuation due to the bottom plate (23A) and prevents mud from flowing into the groove from the bottom plate (23A) side.

As shown by the imaginary line in Figure 1, this tape seedling transplanter (1
