Abstract

PURPOSE:To smoothly pull out a tape seedling from a housing case by increasing the relative interval between a tape seedling receiving surface and a tape seedling feeder of the housing case with increasing housing height of the tape seedling housed in a zigzag state in the housing case. CONSTITUTION:A tape seedling housing case 1 is provided so as to vertically move relatively to a feeder 2 for feeding blocklike seedlings (a) formed into a tape seedling to the housing case 1 and the tape seedling is housed in the housing case 1 in a zigzag state. The housing case 1 is separated from the tape seedling feeder 2 with increasing housing height of the tape seedling.

Description

[Detailed description of the invention] [Industrial application field] The present invention sequentially divides block-shaped seedlings into individual plants.
A device for feeding taped seedlings created using continuous tape attached at predetermined intervals along the longitudinal direction of the tape; and a device for feeding taped seedlings that are attached at predetermined intervals along the longitudinal direction of the tape, and the block-shaped seedlings that are continuously fed out from the feeding device are weighted vertically so that the block-shaped seedlings are laid down sideways and folded. Regarding the tape seedling transplanter that is equipped with a storage case that stores the tape seedlings in a matching state, to be more specific, the storage state of the tape seedlings in the storage case is such that the tape seedlings are placed on their side and stacked one on top of the other in a zigzag manner. As can be seen when wrapping tape seedlings around a block-shaped seedling, since the volume of the block-shaped seedling itself is larger at the base of the plant, the wound state becomes a truncated cone, and eventually,
This invention relates to a tape seedling transplanter that has the advantage of avoiding self-destruction.

[Conventional technology]

Conventionally, the height relationship between the device for supplying tape seedlings and the storage case during the storage operation has always been constant.

[Problem to be solved by the invention]

However, as the tape seedlings are stored on the bottom of the storage case in a state where they are vertically stacked, the actual height between the tape seedling feeding device and the tape seedling placement surface on the storage container side changes.

Therefore, if the above-mentioned heights are different, the tape seedling itself is likely to be twisted or tilted due to the weight of the plant base, and the posture may be distorted when placed in the storage container, resulting in uneven distribution of the tape seedlings and the storage container itself. At the time of planting, the taped seedlings could not be pulled out properly due to imbalance or entanglement of block-shaped seedlings.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tape seedling transplanter that can keep the tape seedlings stored in a constant posture and smoothly pull out the tape seedlings from the storage case.

[Means to solve the problem]

Characteristic configurations according to the present invention include: (1) at least one of the storage case and the supply device is configured to be movable in the far and near directions; (2) the storage height of the tape seedlings stored in the storage case in a folded state; The higher the height, the greater the relative distance between the tape seedling receiving surface of the storage case and the feeding device, and its effects are as follows.

[For production]

That is, as shown in FIG. 5, for example, by separating the storage case (1) from the tape seedling supply device (2) as the tape seedling storage height increases, the tape seedling storage case The falling height can always be kept constant.

Therefore, it is possible to suppress changes in the posture of the tape seedlings during the fall due to different falling heights and the resulting disturbance in placement within the storage case.

〔Effect of the invention〕

As a result, there was a lack of posture balance in the storage case due to uneven distribution of tape seedlings due to disordered placement within the storage case, and
It is possible to avoid poor feeding and poor planting due to entanglement of tape seedlings in a placed state.

〔Example〕

As shown in FIG. 5, the tape seedling transplanting machine has a feeding device ( 2) and a tape seedling storage case (1) that moves up and down with respect to the feeding device (2), and is used for planting rushes, rye, etc.

As shown in FIGS. 2 and 5, the supply device (2) is provided on a pair of left and right synchronous belt conveyors (3) (3) and one of the conveyors (3) so that its posture can be changed. A lower continuous tape (5A) that is positioned between a block-shaped bacterial strain base holder (4) and a pair of left and right belt conveyors (3), and moves while supporting the block-shaped seedling (a); It consists of a belt conveyor (3), and an upper continuous tape (5B) that overlaps the lower continuous tape (5A) at the end position of the belt conveyor (3) and holds the block-shaped seedlings (a). As shown in FIG. 2, the block-shaped bacterial strain base holder (4) is pivotally supported on one belt conveyor (3) so that it can freely swing up and down, and when the block-shaped seedlings (a) are stored. As shown in Fig. 2, the seedling is held in an approximately 45° inclined position by the first guide rod (6), and after storing the block-shaped seedling (a), the block-shaped seedling (a) is held in a tilted position as shown in Fig. 3. The second guide rod (7) causes the seedling (a) to fall sideways so that it is placed on both belt conveyors (3), (3). Therefore, the position of the plant base of the block-shaped seedlings (a) when conveyed by the belt conveyors (3), (3) can be always controlled to be constant, and the holding position of the tapes (5A), (5B) can be adjusted from the plant base. Can be placed in a certain upward position.

Lateral movement of the storage case (1) will be explained. The storage case (1) is attached to a vertical support frame (9) so as to be movable up and down, and the support frame (9) is attached to a moving table (10) so that it can be moved laterally. As shown in Figs. 4 and 5, this moving platform (10) is supported by left and right guides (11), (11) and slides, and the horizontally rotating chain (12)
) is laterally movably driven. This sideways chain (12) and the moving table (10) are connected to the moving table (10).
) and the interlocking pin (14) extending from the chain (12
) are interlocked. In the figure (
13) is a motor for driving the chain (12).

Next, the vertical movement mechanism (8) of the storage case (1) will be explained. As shown in FIG. 1, the vertical movement mechanism (8
) includes a vertical rack (16) formed on the support frame (9), and a movable frame (1) that moves up and down with respect to the support frame (9) integrally with the storage case (1).
7) a pinion (18) supported within the interior space surrounded by the movable frame (17) and engaged with the rack (16);
, a bracket (19) supported so as to be vertically swingable at the axial center position of the pinion (18), and this bracket I-(19).
) is supported in a vertically swingable manner and has a distal end protrusion urged to engage with the pinion (18).
, a check claw (21) that prevents the storage case (1) from moving downward within the biasing force of the spring (22), and the movable frame (17).
) (19)
and an operating arm (24) connected via a connecting arm (23). This operating arm (24) is connected to a pulling wire (25) extending from a stop point that is in a stopped state with respect to the lateral movement of the lateral movement table (10), and swings at the moving end of the lateral movement table (10). dynamically driven.

To explain the movement of the above configuration, ■ As shown in Figure 1 (b), the storage case (1)
When it reaches one lateral movement end, the operating arm (24) is rotated downward as shown by the arrow, and the bracket (19) is rotated downward via the connecting arm (23). be done.

■ Then, the engagement piece (20) attached to this bracket (19) engages with the pinion (18) and rotates the pinion (18), lowering the storage case (1) by a predetermined amount. let

■ When the moving platform (10) reaches the other lateral movement end from this state, the operating arm (24) is now oscillated in the opposite direction as shown in FIG. The bracket (19) is also driven to swing in the same direction.

(2) Then, the engaging piece (20), like a ratchet pawl, climbs over both sides of the pinion (18) and rotates in the same direction as the bracket (19). At this time, since the pinion (18) is not rotating, the storage case (1) does not move downward.

As described above, when the storage case (1) reaches the position indicated by the solid line in FIG.
The descending height of the tape seedlings from 2) to the tape seedling receiving surface of the storage case (1) can always be kept constant.
