Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transplanting machine for transplanting block seedlings.

[Conventional technology]

In a transplanting machine for transplanting block seedlings, the machine frame is equipped with a seedling supply device, a planting device, and a drive wheel that rolls on the ground to drive these seedling supply device and planting device. There is.

In the seedling feeding device, seedling tubes into which block seedlings are placed are arranged radially on a seedling tube support base, and the seedling tubes are intermittently driven around a vertical axis so that the lower end opening of the seedling tube is positioned at a predetermined position on the support base. Make sure to open it at the position,
The block seedlings in the seedling cylinder are made to fall.

In addition, the planting device is equipped with a seedling supply device and a transplant tube that moves up and down between the furrows, and after the transplant tube catches the block seedlings that have fallen from the seedling tube, it is inserted into the furrow to transfer the block seedlings. Plant in rows.

By the way, in the past, the above-mentioned seedling supply device, planting device, and drive wheel were separately provided in the machine frame.

[Problem that the invention attempts to solve]

For this reason, it is not easy to perform adjustment operations to correspond to the height of the ridges, and the interlocking relationships and various timings of the seedling supply device, planting device, and drive wheels are also likely to be disrupted by this adjustment operation. Moreover, this resulted in a more complicated structure. Furthermore, since the distance from the seedling supply device to the planting device is long and the block seedlings are dropped, the block seedlings may be damaged or tilted.

The present invention is easy to adjust to accommodate the height of the ridge, and does not disrupt the interlocking relationships and various timings of each device and drive wheel for transplanting block seedlings. Moreover, it is an object of the present invention to provide a transplanter that can transport block seedlings from above to a planting device near a ridge without dropping them.

In the planting device 18, when the pair of left and right clamping arms 63 come to the diagonally upper front side of the support shaft 61, the roller 65 is moved to the upper guide rod 66.
When the upper guide rods 6 are opened by being guided by the upper guide rods 69 and the upper guide rods 6
The release of both clamping arms 53 by 6 is released, and both clamping arms 63 clamp the block soil 40a of the block seedling 40.

In this state, the transport table 56 on which the block seedling 40 was placed moves away from the block seedling 40 as shown by the imaginary line in FIG. When the roller 65 rotates approximately 1/4 of a turn around the shaft 61, both clamping arms 63 are opened as the roller 65 is guided by the lower guide rod 67, and the block seedling 40 that was being clamped is placed in a state with the stems and leaves 40b facing upward. Then, the groove cutter 16 is dropped between the rear sides of both side plates 44 and transplanted into the transplant groove 42.

Next, the left and right soil covering compaction wheels 19 scoop up the soil in the ridge 41 between both compaction wheels 19, and transfer this soil to the transplant groove 4.
2, supply 40 blocks of soil for 40 block seedlings.
A is buried in the ridge 41, and both sides of the block seedling 40 are crushed.

Note that even when the planting device 18 and the conveyor device 17 are reversed due to other reasons such as a conveyance jam of the block seedlings 40, a chamfered portion 60 is formed on the protruding portion 59 of the conveyance table 56, and the clamping arm 63 Since the rear side chamfer 74 is formed in the rear side, there is no risk of interference between the clamping arm 63 and the conveyance table 56.

In the above embodiment, the transplant frame 14 was provided so as to be able to move up and down around the support shaft 24, but as shown by the phantom line in FIG. 1, the front side plate 2 of the transplant frame 14
1 may be provided to be vertically movable parallel to the bracket 27 via a parallel link mechanism 109 consisting of a pair of upper and lower links 108.

FIG. 7 shows a second embodiment of the present invention, in which one arm portion 6 of the corresponding left and right clamping arms 63 is shown.
8, the adjustment bolt 111 is inserted from the outside so as to be movable and adjustable in the left and right direction, and the lock nut 112 is inserted into the lock nut 112.
