Description

DETAILED DESCRIPTION OF THE INVENTION This invention sequentially moves the seedlings back and forth between the top and bottom of the planting device as the seven seedlings on the m-supply table that are held horizontally move.
This invention relates to a planting drive mechanism in an m-transplanter VC for planting.

In order to drive the movement of the seedling feeding table, the extrusion of the seedling extrusion rod, and the vertical movement of the planting rod, it is necessary to perform each operation without any deviation in timing. In order to keep these drive mechanisms from becoming heavy, it is necessary to make these drive mechanisms simple; It is fully equipped with a device for pushing out seedlings that fall down, and a planting device that receives the fallen seedlings, moves down to the planting surface, opens its planting claws, and plants the seedlings. Regarding the transplanter, the extrusion operation of the seedling extrusion rod of the seedling extrusion device, the up and down movement of the planting link of the planting device, and the opening and closing operation of the planting claw are all driven by a single crank t% drive shaft. The system is constructed so that each of the above-mentioned operations for planting east can be performed with a simple drive mechanism without any lag in timing.

At this point, attach the hollow cylinder (to), and insert the planting claw (to) into the long hole of the opening/closing rod (41) through the arm Qt.
The crank (An) is fixed to the drive shaft leg 1, and connected by the link (to), crank (c) and t-arm (a), and the crank bin (44) is attached to the opening/closing rod 1411. When connected and the drive shaft rotates in the direction of the arrow in Fig. 1,

With this opening movement of the seedlings (4611t1), they are released into the planting holes drilled in the ridges, and then planted together with the planting links. When the claw C (to) moves upward, the hollow cylinder CI moves downward together with the opening/closing rod j411 and approaches the planting claw (to), so the opening/closing link CIl CI on the right of the craftsman is in an inverted V-shape. As shown in Fig. 5, it is constructed into L parts in which the planting claws (to) are closed by making springs (S7).Then, as shown in Fig. 5, when planting When the claw (to) 31 and the hollow cylinder (7) are at the uppermost position, close to just under the holding loincloth, which is provided directly under the seedling extrusion rod α→, the bottom M coupling of the lower end opening of the holding simple When opened, the moe (IQ) that had been hooked on the bottom M4 until then is configured to fall into the holding cylinder <48.

That is, the bottom cover (which is attached to the holding cylinder) in the bottle group.

The mutual operational relationship between the and seedling supply table (8) is as follows:
While the is moving downward from the uppermost position I# to the lowermost position, the seedling extrusion rod) performs extrusion operation, the foil supply table CM1J stops operating [7ZJ, and the planting claw (toward ) (to) moves upward from the lowest position η to the uppermost position, the moe push rod (1 → stops + at the upper position of the seedling supply stand (9)
At this time, the intermittent rotation mechanism I33 operates in a manner similar to the movement of the foil supply table 01).The intermittent rotation mechanism I33 is exemplified as an example of the intermittent rotation mechanism 4+3.
The engine haze shown in Fig. 1 drives the drive sprocket wheel loosely fitted onto the rotating shaft (6a) shown in Figs. When operated, the operating pin 6a interlocked with this moves backward, and the clutch retainer energized by the spring engages with the drive tin rocket wheel, so the rotating shaft rotates and the gear train r6η The drive shaft (2) rotates, and behind it the planting link CL'il (g) and the opening/closing rod puller move up and down, and the seedling extrusion rod Oa is structured into a gill that makes a sound when moving up and down. ing.

℃, and this lateral movement is formed at l pitch of the title storage section 115). In addition, a lead claw ('/4) that engages with the groove of the lead cam +51 is fixed to the lead gear (il).
Currently, it is driven by a transmission mechanism (engineered by the national government on a rotating shaft).

In the illustrated example, the seedling pushing out operation and the opening/closing operation of the planting claw are both performed by one crank (■), but two separate cranks are used for each operation. It may be a structure in which this is done.

The above-mentioned movement mechanism of the seedling supply platform, and the seedling extrusion device aS
The planting device G1 and the like are not limited to the one shown in the drawings, but can be used in various ways that have similar functions.

The planting drive mechanism of the seedling transplanter according to the present invention is configured as described above, and includes the pushing operation of the seedling extrusion rod (4), the vertical movement of the planting link CI!9@, and the planting claw (4). Since each of the opening and closing operations is driven by a single drive shaft (II/C), the above-mentioned trough operation will be performed accurately without any deviation in timing.
Moreover, the drive mechanism was simple and did not require any special synchronization mechanism, and the VC could be easily used.
