Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a seedling storage section for storing tape seedlings, which is formed by attaching a crop seedling bundle at a predetermined interval to the tape, In order to store it in the seedling storage section in a zigzag shape while being overlapped with each other, a mechanism for raising and lowering this seedling storage section and a mechanism for reciprocating left and right are provided, and this mechanism for reciprocating is driven by a rotating endless belt type drive. The present invention relates to a seedling storage mechanism of a tape seedling making apparatus, which is composed of a mechanism and a linking mechanism that links the drive mechanism and the seedling storage section.

[Conventional technology]

In the seedling storage mechanism of this kind of tape seedling making apparatus, conventionally, the drive mechanism and the seedling storage section are connected by a fixed linking mechanism such as a bolt.

[Problems to be solved by the device]

Therefore, for example, when a predetermined amount of tape seedlings are stored in the seedling storage unit and the seedling storage unit is removed from the tape seedling making device and replaced with the tape seedling planting device, it is suitable to remove the seedling storage unit. Since good tools were required, workability was not good. Moreover, since the seedling storage portion is driven to reciprocally slide in the endless belt of rotation, a link mechanism capable of absorbing the relative displacement between the two is usually provided as a linking mechanism between the two.

It is an object of the present invention to provide a structure in which the linkage mechanism is rational so that the seedling container can be easily attached to and detached from the drive mechanism.

[Means for Solving the Problems]

A characteristic configuration according to the present invention is that the linkage mechanism is connected and fixed to the rotary endless belt drive mechanism, and an engagement portion thereof moves on a straight line connecting left and right reversal centers of the rotary endless belt drive mechanism. An engaging portion, and a second engaging portion that is detachably attached to the first engaging portion and attached to the seedling storage portion, and the first engaging portion and the second engaging portion. The drive mechanism and the seedling storage section are released based on the operation of releasing the connection to the connecting pin to be engaged. The operation and effect thereof are as follows.

[Action]

That is, as shown in FIGS. 1 and 2, the drive mechanism (12) is configured so that the first engaging portion (25) is positioned on the straight line connecting the left and right reversing centers (X) and (X). Is a rotation endless belt type and is rotated in one direction, the first engaging portion (25) reciprocates on the straight line.

Therefore, only the first engaging portion (25) and the second engaging portion (26) from the seedling storage portion (1) are used for the linkage mechanism (17).
And a connecting pin (2) that connects the two (25) and (26).
The linkage can be easily released by the connection release operation by inserting and removing in 7).

As an actual operation, as shown in FIG. 1, the connecting pin (27) is pulled out, the case support (4) is moved to the outside of the machine frame (28), and the case support (4) is moved at its moving end. The upper seedling storage case (1) can be taken out in a comfortable posture.

[Effect of device]

(A) With the configuration in which the first engaging portion is moved on the straight line connecting the left-right reversal centers of the endless belts for rotation, even if the drive mechanism is an endless belt for rotation, a linkage mechanism between the drive mechanism and the seedling storage portion is provided. It can be limited to the first engaging portion and the second engaging portion.

(B) Therefore, it is possible to perform a one-touch operation by simply releasing the connection between the first and second engaging portions without adopting a link mechanism or the like between the endless rotation belt that moves on the endless rotation track and the seedling storage portion that moves linearly. Since a possible connecting pin method can be adopted,
The operability of disconnecting the seedling storage portion from the drive mechanism can be improved.

Therefore, even if the drive mechanism is not stopped at a fixed position, the connection pin can be removed and the seedling storage section can be pulled out to an arbitrary position and taken out in a state where the work can be performed easily. In particular, when the seedling storage portion and the drive mechanism are located in the frame of the machine body frame, the seedling storage portion can be pulled out to any position, so that the seedling storage portion can be taken out easily.

The connection between the first engagement portion (25) and the second engagement portion (26) can be released by inserting and removing the connection pin (27). That is, as shown in FIG. 2, the first engaging portion (25) is fixed to the link of the transverse chain (12) and extends inward in a cantilever manner. The engagement hole (25a) is traversed and is positioned on the line connecting the left and right reversing centers (X) of the chain (12). Therefore, when the lateral rotation type chain (12) rotates in one direction, the first engaging portion (25) reciprocates along the straight path and the center of reversal along the reversing path, as shown in FIG. Since rotation is performed around (X), the engagement hole (25
a) stops on the reversal center (X).

On the other hand, the second engaging portion (26) has a right and left reversing center (X),
It is located on a line connecting (X) and is connected to the engagement hole (25a) by a connecting pin (27), and reciprocates the storage case (1) and the support frame (9) integrally. However, when the first engaging portion (25) is on a curved road, the storage case and the support frame (9) are in a stopped state. The connecting pin (27) is attached to the holder (26a) of the second engaging portion (26) and is urged to project toward the first engaging portion (25) to pull up against the urging force. When operated, the engagement with the second engagement portion (26) is released.
