Description

[Detailed Description of the Invention] This invention relates to a seedling turning device interposed between a planting device and a seedling feeding device in a transplanter for transplanting tobacco seedlings, cabbage seedlings, etc. to a field.

Tobacco seedlings, etc. that are planted using a transplanter are planted with the roots of the seedlings in a soil retaining body. Therefore, when feeding the seedlings to the seedling holder of the planting device, it is necessary to feed the seedlings in an upright position. If the posture of the seedlings is uneven, there is a risk that the supply of seedlings will be hindered and it will be difficult to perform the work smoothly.

In view of the above-mentioned points, in this case, a planting device 2 is installed on the traveling machine 1 for the purpose of correcting the posture of seedlings and ensuring reliable feeding when feeding seedlings, and a seedling feeding device is installed above the planting device 2. 3 is provided in the seedling supply device of a transplanter that supplies seedlings placed sideways on the same seedling supply device 3 by dropping them to the seedling holder 4 of the planting device 2. The base end of a seedling posture correcting shutter 5 is pivotally supported on the machine frame between it and the seedling holder 4, and when the seedling is placed on its side, the shutter rotates downward to bring the seedling into an upright position. It is an object of the present invention to provide a turning device configured to drop and supply seedlings to a seedling holder while turning the seedlings.

To explain the embodiment shown in the drawings, 1 is a traveling machine as a transplant machine, and an engine 7 is installed at the front of a machine base 6.
A drive transmission 8 is mounted on the tower, which is connected to the engine I, and a running wheel 10 is provided to the engine 1 via a transmission 3, and an operation handle 11 is provided at the rear of the fuselage 1, and a guide wheel is installed at the front. There are 12.

Reference numeral 2 denotes a planting device, which supports a direct holding body 4 by the tips of a pair of F-shaped rings 13.13 (7) that are shifted in the front and back positions, and has a swinging device attached to the other end of the link 13.13. moving arm 1
4 is pivotally supported, and a crank arm 15 is pivotally supported in the middle of the link 13.13, and by rotating the crank arm 15, the seedling holder 4 can be held in the center of the machine body 1 as shown in FIG. The robot is moved up and down in a reciprocating manner along a trajectory shown by a virtual line.

The seedling holder 4 rotatably supports a pair of cup halves 16.16, which are made by dividing an inverted conical cylinder in half, between the tips of the links 13.13, and has an upper end opening inside the cup halves 16.16. It supports a seedling guide tube 18 whose portion 17 is circular, and the lower end opening 18 of the seedling guide tube 18 is connected to the half-cup body 16.1.
It can be opened and closed freely by the rotational movement of 6.

When transplanting the seedlings 20 supplied to the C seedling holding body 4, the seedling holding body 4 is lowered by lowering the planting device 2 as the crank arm 15 rotates and penetrates into the field. The cup body 16.16 was opened to enlarge the planting hole in the penetration part, and the lower end opening 19 of the seedling guide cylinder 18 was opened to allow the seedling 29 to fall into the planting hole, and the seedling 20 was transplanted to the field. Later, as the planting device 2 rises with the rotation of the crank arm 15, the half-cup body 16.16 is rotated to close the lower end opening 19 of the guide tube 18 and raise the seedling holder 4. .

3 is a seedling feeding device provided above the planting device 2;
A vertical conveyance belt 21 configured to be able to move intermittently supports a machine frame 22, and a horizontal conveyance belt device 23 is adjacent to the transition end portion of the vertical conveyance belt device 21 via a stage so as to be able to rotate intermittently,
And the vertical conveyance belt device 21 is a horizontal conveyance belt device 23.
These are connected in series to perform one intermittent transition through several intermittent transitions.

24 is a seedling mounting device provided above the seedling feeding device 3;
A guide rail 25 is provided that extends directly above the transfer start end of the vertical conveyance belt device 21, and the seedlings 20 in the seedling box 26, which holds the stored seedlings so as to fall freely, are dropped on the guide rail 25 in the state 11, thereby vertically conveying. The seedlings 20 can be arranged and placed on the belt device 21.

Reference numeral 27 denotes a seedling turning device of the present invention which is interposed between the seedling feeding device 3 and the planting device 2, and is provided adjacent to the transition end portion of the horizontal conveying belt device 23, and is pivoted to the machine frame 22. pin 28
The seedling posture correction shutter 5 is pivotally supported on the same pivot pin 28 so as to be rotatable in a direction perpendicular to the direction of movement of the horizontal conveyance belt device 23.

The correction shutter 5 is composed of a support plate 30 having a side plate 29 on the side adjacent to the horizontal conveyance belt device 23, and a downward balance weight 31 connected to the base end of the support plate 30. The pin 28 is interposed between the support plate 30 and the crane weight 31.

32 is a rotation stopper of the correction shutter 5;
The correction shutter 5 is in contact with the balance weight 31.
The support plate 30 is held in a horizontal state as shown in FIG. 3 except when the seedlings 20 are being fed.

Note that the reference numeral 33 is a preliminary mounting portion of the seedling raising box 28.

Therefore, the seedlings 2 are placed in the seedling box 26 placed on the guide rail 25.
0 is dropped and placed on the vertical conveyance belt device 21, and the seedling 20
are sequentially transferred by the intermittent transfer of the vertical conveyance belt device 21 and transferred from the end of transfer to the horizontal conveyance belt device 23. At this time, the intermittent transfer of the vertical conveyance belt device 21 transfers the seedlings 20 in the front row. The seedlings 20 in the second row are transferred from the side to the horizontal conveyance belt device 23 by being laid down from the side via a row, and the seedlings 20 in the second row are transferred to the front row.

The seedlings 2 were then placed sideways on the horizontal conveyor belt device 23.
0 is sequentially transferred by intermittent transfer of the horizontal conveyance belt device 23, and is dropped and supplied to the seedling holder 4 from the transfer end via the correction shutter 5.

At this time, the seedlings 20 that fall horizontally move onto the support plate 30 of the shutter 5, and their weight causes the support plate 33 to rotate downward against the weight of the balance weight 31, and at that point it turns upright. The seedling holder 4 slides down on the rotating support plate 30 while changing its orientation, and is supplied to the seedling holder 4 located at the upper end of the trajectory while changing its orientation to an upright position.

After feeding, the support plate 30 quickly rotates upward due to the weight of the balance weight 31, and the horizontal conveyance belt device 2
3, the next seedling 20 is held in a horizontal state and is awaited for migration.

Since the present invention is configured as described above, it is possible to correct seedlings that are in a horizontal position to an upright position and reliably feed them to the seedling holder. This has the effect of reducing damage to the holding body and allowing work to be carried out smoothly.
