Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a seedling storage section for storing tape seedlings formed by attaching crop seedling bundles at predetermined intervals in the longitudinal direction of the tape in a twisted manner. The present invention relates to a tape seedling planting device that is provided with a feeding device that takes out the tape seedlings from the starting end and feeds them toward a planting section.

[Conventional technology]

Conventionally, this type of tape seedling planting device has not been provided with a means for knowing that the end of the tape seedlings that have been folded and stacked in the seedling storage section has been taken out from the seedling storage section.

[Problem to be solved by the invention]

Therefore, the operator often notices that the seedling storage section has already run out of taped seedlings, and the next seedling supply cannot be made in time, often leading to inconvenient situations such as missing plants.

An object of the present invention is to provide a device that can improve workability by providing a simple mechanism.

[Means to solve the problem]

The characteristic configuration according to the present invention includes a detection mechanism for detecting the movement of the end of the tape seedling due to the feeding of the tape seedling, and
The present invention is provided with a control device that operates an alarm device based on the detection operation of this detection mechanism, and its effects are as follows.

[For production]

In other words, when tape seedlings stored in a zigzag manner are unwound one after another and the end of the tape seedling located at the lowest position is pulled and moved, a detection arm that locks the end of the tape seedling, as shown in Fig. 1, for example. (18) is rotated by being pulled by the tape (1 or 2), and a limit switch (20) as a detection mechanism that is in contact with this detection arm (18) is turned off.

In this case, the movement of the end of the tape seedling may be detected by a non-contact sensor such as an optical sensor instead of the limit switch (20).

Therefore, when the worker learns of the movement of the terminal end, the worker supplies the next tape seedling to the seedling storage section, and for example, in the case where the seedling attached to the tape is cut and planted while attached to the tape, Work such as connecting the end of a tape to the start of the next tape is performed.

〔Effect of the invention〕

By simply modifying the system to provide a detection mechanism that detects movement of the terminal end of the tape seedlings, continuous work can be performed even in a limited tape seedling storage area. or,
Planting work is not continued when there are no tape seedlings to be planted.

[First Embodiment] A tape seedling transplanter used, for example, connected to the rear end of a passenger car body (not shown) will be described.

Before planting with this tape seedling transplanter, a plurality of crop seedling bundles (a) are arranged and held at predetermined intervals in the longitudinal direction of two long tapes (1) and (2). Create seedlings. Here, the crop seedlings targeted are rush and rye. The tape seedling transplanting machine includes a seedling storage section (3) that stores the tape seedlings in a vertically folded manner.
and a feeding device (23) that feeds out the seedling storage portion (3) toward the planting portion (4). The feeding device (2
3) is a first guide roll (5) that changes the traveling direction of the tape seedling transplanter suspended from the seedling storage part (3), and a pair of upper and lower guide rolls (6A) that guide the lower side of the first guide roll (5).
(6B), a pair of separation rolls (7A) that separate both tapes (1) and (2) at the delivery site to the planting section (4),
(7B) and the separated tapes (1) and (2
), a pair of upper and lower winding drive rolls (8A), (8
B). This winding drive roll (8A), (8
B) is a feed case (
9) More powered. The upper winding twin drive roll (8
A) has a sliding mechanism (1
0), and this sliding mechanism (10) controls the winding speed of the tape (1) wound on the drive roll (8A) and the winding speed of the tape (2) wound on the lower double drive roll (8B). A structure is adopted to absorb the deviation from the taking speed.

The upper guide roll (6A) of the pair of upper and lower guide rolls (6A) and (6B) is attached to one end of the swinging arm (11) and is biased in a direction to press down the tape seedling, so that the tape seedling is fed out due to inertia. The structure is designed to prevent overflow.

The planting part (4) includes the separation roll (7A), (7
A scraping rotating body (12) that scrapes the seedlings separated in B), a dropping chute (13) that drops the seedlings scraped by the scraping rotating body (12) onto the planting surface, and a dropping chute (13) that drops the seedlings scraped onto the planting surface. It consists of a soil gathering tool (I4) that gathers soil against the crop seedling bundle (a) that stands on its own. The scraping rotary body (I2) has a rotating disc (12A) formed with a plurality of scraping protrusions (12a), and the scraping protrusions (12a) are used to scrape the stock with the base facing downward. A pushing tool (15) is provided for pressing the crop seedling bundle (a) against the guide surface of the dropping chute (13) while allowing it to fall. A plurality of the pushing tools (15) are attached to the rotating disk (12A), and are urged toward the retracting side, and the cam (
12b). In the figure, (16) indicates the crop seedling bundle (which is being pushed out and dropped by the pusher (15)).
It is a rotating body that applies acceleration by acting on a). The soil gathering tool (14) is disposed on both sides of the falling shoe (13), is freely rotatably supported at the tip of a swinging arm (17) that swings up and down, and is biased downward by a spring.

Next, the treatment of the end portion of the tape seedling in the seedling storage section (3) will be explained.

The end of the tape seedling placed on the bottom of the seedling storage section (3) is made to protrude outward from the seedling storage wall, and the end of the tape is clamped from above and below by one end of the horizontally swinging detection arm (18). It is fixed via a protruding holding mechanism. A massing mechanism (19) is provided at the swing axis position of the detection arm (I8) to restrict the swing of the detection arm (18) when the moving force of the tape seedlings is below a predetermined level. The detection arm (18) is configured not to operate in response to minute movements of the seedling. Therefore, as the tape seedlings are fed out and the end of the tape seedling moves against the massaging mechanism (19), it is pulled by it and rotates the detection arm (18), which turns it into the ON state. The limit switch (2o) is switched to the OFF state.

Therefore, when the limit switch (20) is activated, the alarm device (22) is activated via the control device (21).

On the other hand, the end of the tape seedling leaves the clamping conveyance of the detection arm (18) and is fed out toward the planting section (4).

[Second Embodiment] As shown in Fig. 4, a plurality of seedling storage units (3) are arranged in parallel to enable planting of multiple rows, and crop seedling bundles held in a horizontal position are attached with tape. The crop seedling bundle (a) is pulled out from the seedling storage section (3) while being held in the middle and dropped, and midway through, the attitude of the crop seedling bundle (a) is changed back and forth, cut by the cutting mechanism (25), and released onto the dropping chute (13). Plant with planting nails.

A feeding device (23) is provided above the cutting mechanism (25) for conveying tape seedlings in a hanging manner, and this feeding device (23)
), as shown in Figure 5, the left and right belt conveying devices (2
3A) and (23B), and a plurality of protrusions (23a) are provided on the belt surface of one belt conveying device (23A).

The protrusions (23a) are arranged in parallel at both ends of the belt in the width direction, and are provided at a predetermined pitch in the longitudinal direction of the belt.

The belt of the other belt conveying device (23B) is arranged so as to fit between the left and right protrusions (23a), (23a) located at both ends in the belt width direction.
