Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a seedling storage unit for storing tape seedlings formed by attaching a bundle of crop seedlings at predetermined intervals in the longitudinal direction of the tape in a zigzag folded state. The present invention relates to a tape seedling planting device which is provided with a feeding device for taking out from the starting end of the tape seedling and feeding it toward the planting part.

[Conventional technology]

Conventionally, in this kind of tape seedling planting device, there is no particular means for knowing that the end of the tape seedlings stacked and stored in the seedling storage portion in a zigzag shape has been taken out from the seedling storage portion.

[Problems to be Solved by the Invention]

Therefore, it may be noticed that the operator has to supply seedlings to the seedling storage section after all the tape seedlings stored in the seedling storage section have been fed out and the tape seedlings have already disappeared from the seedling storage section. In many cases like this,
The next seedling replenishment was not in time, leading to inconveniences such as missing stock.

An object of the present invention is to provide a work mechanism capable of improving workability by providing a simple mechanism.

[Means for Solving the Problems]

A characteristic configuration according to the present invention is to provide a seedling storage portion for storing a tape seedling formed by attaching a crop seedling bundle at a predetermined interval in the longitudinal direction of the tape in a zigzag state, and take out from the starting end of the tape seedling. In the tape seedling planting device equipped with a feeding device for feeding the seedlings toward the planting part, a detection mechanism for detecting the movement of the tape seedling end portion in the feeding direction to the lower side in the feeding direction due to consumption of the tape seedlings is provided. In addition to being provided, a control device for activating the alarm device based on the detection operation of the detection mechanism is provided.

[Action]

In other words, the tape seedlings stored in a zigzag shape are sequentially fed out as they are consumed, and when the tape seedling end located at the lowest position is finally pulled and moved to the lower side in the feeding direction, the detection mechanism detects the movement. Upon detection, the detection signal is output to the control device, and the control device activates the alarm device based on the detection signal to prompt the worker to supply seedlings. Therefore, the worker should supply the next tape seedling to the seedling storage portion based on the operation of the alarm device.

By the way, as the detection mechanism, for example, as shown in FIG. 1, the tape seedling end is rotated by being pulled by the tape (1 or 2) as the tape seedling end portion moves downward in the feeding direction. Rotation of the detection arm (18) that locks the part and the detection arm (18) accompanying the movement of the tape seedling end part to the lower side in the feeding direction causes the detection arm (18) to come into contact with the detection arm from the ON state. (18) separated from the limit switch (20) that switches to the OFF state,
Alternatively, it is possible to employ a non-contact type sensor such as an optical sensor that directly or indirectly detects the movement of the tape seedling end portion to the lower side in the feeding direction. In addition, as the replenishment work, for example, in the case where the seedling attached to the tape is cut and planted while attached to the tape, the work of connecting the end of the tape and the start of the next tape is performed. I'll do it.

〔The invention's effect〕

By simply modifying the detection mechanism to detect the movement of the end of the tape seedling, it is possible to easily and accurately recognize the timing of seedling replenishment by the operation of the alarm device, at which point the next tape seedling is seeded. If the storage section is replenished, continuous work can be performed even with a limited tape seedling storage section. Also, the planting work will not be continued in the state where the tape seedlings to be planted are exhausted.

[First Embodiment] For example, a tape seedling transplanting machine used by being connected to a rear end of a passenger car body (not shown) will be described. Before being planted by this tape seedling transplanter, a tape which is previously sandwiched with a plurality of crop seedling bundles (a) arranged at predetermined intervals in the longitudinal direction of the two long tapes (1) and (2). Create seedlings.
Here, strawberries and rye are targeted as crop seedlings. As shown in FIG. 2, the tape seedling transplanter has a seedling storage portion (3) that stores the tape seedlings in a folded manner in a state of being folded up and down, and a planting portion (4) from the seedling storage portion (3). And a feeding device (23) for feeding toward. As shown in FIG. 3, the feeding device (23) guides the tape seedlings hung from the seedling storage section (3) with a first guide roll (5) for changing the feeding direction and a lower side thereof. A pair of upper and lower guide rolls (6A) and (6B), and a pair of separation rolls (7A) and (7B) for separating both tapes (1) and (2) at the delivery site to the planting section (4) , A pair of upper and lower winding drive rolls (8) for winding the respective separated tapes (1), (2)
It consists of A) and (8B). This winding drive roll (8A),
(8B) receives power from a feed case (9) that receives power from the passenger vehicle side. The upper winding drive roll (8A) is provided with a slip mechanism (10) that slips under a certain load, and the tape (1) wound by the drive roll (8A) is wound by the slip mechanism (10). A structure is adopted to absorb the deviation between the winding speed and the winding speed of the tape (2) wound by the lower winding drive roll (8B).

The upper guide roll (6A) of the pair of upper and lower guide rolls (6A) and (6B) is attached to one end of the swing arm (11) and is urged in a direction to press the tape seedling, and the upper guide roll (6A) is driven by the inertia of the tape seedling. The structure is adopted to prevent overfeeding.

The planting part (4) plants a scraping rotator (12) for scraping off the seedlings separated by the separating rolls (7A), (7B) and a seedling scraped off by the scraping rotator (12). It is composed of a drop chute (13) to be dropped on the attaching surface, and a soil gathering tool (14) for scraping soil against the plant seedling bundle (a) which falls on the planting surface and stands on its own. The scraping rotator (12) forms a plurality of scraping protrusions (12a) on the rotating disc (12A), and scrapes the stock with the scraping protrusions (12a) facing downward. An extruding tool (15) is provided for pressing the plant seedling bundle (a) against the guide surface of the drop chute (13) and dropping it. A plurality of push-out tools (15) are attached to the rotary disk (12A), are urged toward the retracted side, and are taken out by the cam (12b).
In the figure, (16) is a rotating body that acts on the crop seedling bundle (a) being pushed and dropped by the pushing tool (15) to apply acceleration. The earthmoving tool (14) is arranged on both outer sides of the drop chute (13), is supported by a free rotation shaft at the tip of a swing arm (17) that swings up and down, and is biased downward by a spring.

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

As shown in FIG. 1 and FIG. 2, the tape seedling end portion placed on the bottom of the seedling storage portion (3) is projected outward from the seedling storage wall, and the detection arm (18) swings horizontally. ) Is fixed to one end of the tape via an elastic projection-like holding mechanism that holds the tape end from above and below. At the swing axis position of the detection arm (18), there is provided a Masatsu mechanism (19) that regulates the swing of the detection arm (18) with a moving force of the tape seedling below a predetermined level, and the seedling seedling due to machine vibration or the like is used. The detection arm (18) does not operate with respect to the fine movement of the. Therefore, when the tape seedling end moves toward the lower side in the feeding direction accompanying the consumption of the tape seedling and the tape seedling end moves against the Masatsu mechanism (19), the detection arm (18) is rotated by being pulled by this, and this The limit arm (20) that was in the ON state is switched to the OFF state by the detection arm (18). Therefore, when this limit switch (20) is activated, the control device (21)
The alarm device (22) is activated via the. On the other hand, the taper seedling end is delivered toward the planting section (4) apart from the carrying by the detection arm (18).
