Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides block-shaped seedlings for one strain,
Tape seedlings are created by attaching to a continuous tape at regular intervals along the length of the tape to create tape seedlings, transporting the tape seedlings to the planting section, and separating the block seedlings from the tape. Related device.

[Conventional technology]

Conventionally, in the process of making tape seedlings before planting, a continuous tape that holds a block-shaped seedling is taken up by a take-up roll.
The tape is rolled up and unwound, and the tape is unwound and transported to the planting section. Alternatively, the once wound tape seedling is transferred to a roll on the side of the planting device, unwound from this roll and transported to the planting section. The tape seedling production form was adopted (for example, Japanese Utility Model Laid-Open No. 58-117810).

[Problems to be Solved by the Invention]

However, considering the case of winding the tape around the roll, the block-shaped seedlings held by the tape are wound with the plant base on one side and the stem tip on the other side in the axial direction of the roll. Therefore, the winding diameter of the large diameter stock side is larger than that of the stem tip, and the winding state of the tape seedling becomes a truncated cone shape of the large winding diameter of the stock base side. If it becomes extremely large, it may not be possible to wind it or the winding condition may collapse, leaving room for improvement.

An object of the present invention is to provide a seedling storage part that can form a tape seedling once before planting and properly perform the operation of the tape seedling, and efficiently plant seedlings fed from this seedling storage part. The point is to provide things.

[Means for Solving the Problems]

A characteristic configuration according to the present invention is that a block-shaped seedling for one strain divided into strains is sequentially attached to a continuous tape at predetermined intervals along the longitudinal direction of the tape, and the continuous tape attached with the block-shaped seedling is In a posture in which the block-shaped seedlings are in a sideways state, a point for providing a seedling storage section for storing in a zigzag state, and a point for providing a transfer section for transferring the block-shaped seedlings from this seedling storage section to a planting section, The point is to provide a rotating claw that switches the posture of the seedling transported from the transport section from the tape to the horizontal posture by laying it down, and the action and effect are as follows.

[Action]

[Operation of Claim 1] That is, as shown in FIG. 1, the tape seedlings stored in the seedling storage portion are in a state in which the block-shaped seedlings (a) held by the tapes (2) and (3) are laid sideways. Since it is stored in a zigzag folded state (the next tape is stacked on top of the previously stored tape so that it is folded over), the plant base of the block-like seedling (a) is stalk tip part. Since the diameter is larger than that of the above, even if a tape seedling is placed in this seedling storage part (7), the stocker side has a high tilted posture, but as in the conventional method, the tape is wound around the winding roll. In the case of the present invention, unlike the case where the tapes are stacked, the tapes are simply stacked. Therefore, the stacked state is not broken due to the difference in diameter between the root portion and the tip of the stem. Also, since the stacked state is only placing the upper tape on the lower tape, the upper tape is placed on the upper tape with respect to the lower tape. Therefore, when the number of stacking layers increases, the block-shaped seedlings sandwiched by the upper tape are inserted between the adjacent block-shaped seedlings sandwiched by the lower tape due to the weight of the stacked stacks. Becomes smaller and the stacking posture becomes stable.

Therefore, it becomes easy to pull out and convey the tape seedling from the seedling storage portion, and a correction mechanism for correcting the posture of the tape seedling before reaching the planting portion is not required.

〔The invention's effect〕

Therefore, when storing the tape seedlings in the seedling storage section,
Even when the tape seedlings are pulled out from the seedling storage unit for transportation to the planting unit, there is little disturbance in the posture of the tape seedlings inside the seedling storage unit, so there is no need to provide a posture correction mechanism, etc. There is nothing to do.

Moreover, the rotary claw is provided in the planting part, and the rotary claw is acted on the plant base side of the block-shaped seedling to switch the posture of the block-shaped seedling to the vertical direction, and when the plant base part is dropped first, it remains as it is. Since it can be planted, there is an advantage that it is not necessary to provide a mechanism for planting only by providing the posture switching rotary pawl.

[Advantageous Effects in Claim 2] In this case, the surface of the continuous tape holding the block-shaped seedlings is vertically inclined from the sideways direction by the guide surface of the posture switching mechanism including the first guide member during the transportation to the planting section. By guiding the seedlings along the facing posture, the block-shaped seedlings in the lying-down posture can be switched to the vertical posture, and, in the planting part, the block-shaped seedlings are guided by the guide surface of the discharging mechanism including the second guide member. By guiding the two continuous tapes holding each other in a direction away from each other, the block-shaped seedlings switched to the vertical orientation can be released from the continuous tape, and the vertical orientation of the vertical tape released from the continuous tape can be removed. Since the block-shaped seedlings are grasped and planted by the planting claws, the planting can be done reliably, and the planting claws used in the rice transplanter can also be used.

[Advantageous Effects in Claim 3] In this case, the surface of the continuous tape holding the block-shaped seedlings is oriented vertically from the laying direction by the guide surface of the posture switching mechanism including the guide member during the transportation to the planting section. By guiding it along the posture, it is possible to switch the block-shaped seedling in the horizontal sideways posture to the horizontal front-back posture, and in this horizontal front-back posture, cut the continuous tape and plant the block-shaped seedling while holding it with the tape. Therefore, since the block-shaped seedlings are hardly disturbed in posture and are transported in a horizontal front-back posture, they occupy little space in the lateral direction, which is advantageous for multi-row planting.

A tape seedling preparation device is configured by arranging a tape seedling storage case (7) as a storage part. Incidentally, the belt conveyor (1)
For this, the worker takes stocks and puts them into each stock. The tape seedling storage case (7) can be folded and stored sideways, and there is also a method of winding it around a drum, but when winding around this drum, the root of the stock is larger than the tip of the stem. Because of this, the diameter of the stock side becomes larger and the tape wound on the drum becomes a truncated cone, and eventually the wound tape self-destructs, avoiding such self-destruction phenomenon. This is because.

Next, the tape seedling planting device (A) will be described.
