Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is provided with a fertilizer application device in which a fertilizer application device that intermittently feeds fertilizer from a tank and supplies it discontinuously to a field is interlocked with a drive mechanism of a nail for planting seedlings. Regarding the transmission part structure of rice transplanter.

[Conventional technology]

In such a rice transplanter equipped with a fertilizer application, the position of the fertilizer application position relative to the seedling planting position can be changed and adjusted, for example, as disclosed in Japanese Utility Model Laid-Open No. 60-151313. That is, the passive side member mounted on the drive shaft of the fertilizer feeding roll in an integrally rotating state and the drive side swinging member linked to the seedling receiving claw drive mechanism can be integrally swingable in a concentric arrangement. The driving side swinging member is configured to change the relative position of the driving side swinging member and the driving side swinging member in the rotational direction by the action of the elongated hole of the driving side swinging member. Is there. That is, the initial rotation position of the fertilizer feeding roll is changed by adjusting the connection of both members.

[Problems to be solved by the invention]

In the conventional configuration, when changing and adjusting the fertilizer application position, not only the bolt rotating operation for loosening or re-tightening the connecting bolt is necessary, but also the drive side swinging member and the passive side member It took time and effort to adjust the connecting posture.

An object of the present invention is to make it possible to easily change and adjust the sprinkling position of fertilizer.

[Means for solving problems]

The characteristic configuration of the present invention is, in the transmission part structure of the rice transplanter with the fertilizer application described above, for the interlocking rotary body on the transmission upper hand side and the interlocking side on the lower transmission side, which constitutes the interlocking mechanism between the fertilizer application device and the drive mechanism. One of the rotating body and the other is slidably mounted in a direction to move toward and away from the other, and the sliding side interlocking rotary body is slid to perform opening / closing operation, and the sliding side interlocking operation in the engaged state. A point in which a clutch is provided between the interlocking rotary body on the transmission upper hand side and the interlocking rotary body on the lower transmission side in a state in which a connection rotational phase of the other rotary body for rotation with respect to the other interlocking rotary body is changed. And its action and effect are as follows.

[Action]

The relative rotation position of the interlocking rotary body on the transmission upper hand side and the transmission lower hand side for the rotation of the interlocking rotary body on the transmission hand side caused by the transmission from the drive mechanism of the seedling planting pawl when the clutch is disengaged. When it becomes different from the one before the clutch is disengaged, the clutch is put back in and operated so that both interlocking rotary bodies rotate in unison. The deviation from the fertilizer feeding timing changes from that before the clutch operation, and the position of the fertilizer application position with respect to the seedling planting site changes.

〔The invention's effect〕

Since the connecting rotational phase of both motion rotary bodies can be adjusted by the driving force, the adjustment of the fertilizer application position can be done simply by operating the clutch, which is excellent in terms of operation. It became a thing.

〔Example〕

As shown in FIG. 5, two seedlings are planted on both sides of the transmission case (2) connected to the rear part of the operating body (not shown) via the link mechanism (1) so that the transmission case can be freely moved up and down. Rotating body (5) with pawls (4A) and (4B) mounted on the periphery is rotatably mounted via drive shaft (2), and can be reciprocally slidable to the left and right on the transmission case (2). Attach the seedling stand (6) and the grounding float (7), and rotate the rotating body (5) so that the seedling planting claws (4A), (4B) sequentially remove the seedlings from the seedling stand (6). The seedling planting device (A) is configured so as to be taken out and planted in the field.

The transmission case (2) has an engine (not shown) of the traveling body.
When the power from is transmitted, the drive shaft (3) is rotated via the transmission chain (12), the rotating body (5) is rotationally driven, and the seedling is rotated with the rotation of the rotating body (5). Planted nails (4A), (4B)
The drive mechanism of the seedling planting claws (4A), (4B) is configured so that the rotation mechanism is rotated by the gear mechanism (27) inside the rotating body (5).

The fertilizer application device (B) is interlockingly connected to the drive shaft (3),
Next, the drive structure of the fertilizer applicator (B) will be described.
As shown in FIG. 4 and FIG. 4, the power transmission body (13) fixed to the drive shaft (3) and the transmission shaft (14) loosely fitted to the transmission shaft (14) installed above the transmission case (2). A transmission chain (16) wound around the interlocking first rotating body (15) on the upper side, the first rotating body (15) and the first rotating body (15) on the transmission shaft (14).
An interlocking mechanism (D) including a second rotating body (17) for interlocking the transmission, which is externally fitted so as to be slidable toward and away from the
A clutch (C) provided between the first rotating body (15) and the second rotating body (17) so that the second rotating body (17) can be turned on and off by sliding operation, the transmission shaft. A link (20) is provided at one end of (14) for connecting the fixed arm (18) to the drive arms (19) and (19) for driving the pair of feeding rolls (9) and (9). The rotary power of the drive shaft (3) is transmitted to the transmission shaft (14), and the rotary power of the drive shaft (14) drives the rotary shaft via the link (20) and the drive arms (19), (19). When the (21) and (21) are driven, the feeding rolls (9) and (9) are configured to reciprocally rotate at a constant angle.

The clutch (C) is, as shown in FIGS. 2 and 3,
