[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting apparatus for a vegetable transplanter which can transplant a pot seedling by vertically moving a hopper type planting claw.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Patent Application No. 4-112229 already filed by the present applicant, a hopper-type planting claw in which a seedling removal claw can receive a pot seedling taken out from a tray when it is raised. In a vegetable transplanter configured to be able to open and transplant while lowering, the pot seedling that is separated from the seedling removal claw completely falls into the inner bottom of the hopper-type planting claw stopped at the ascending position. From then, the planting claws began to descend.

[0003]

[Problems to be Solved by the Invention] However, when the planting claw starts to descend after the pot seedling completely falls into the inner bottom portion of the planting claw, the pot seedling floats in the air by inertia. The planting claw that has descended opens and falls into the place where the hole was drilled, the pot seedlings fell, so-called rolling seedlings occurred, and the planting accuracy was poor,
The problem was presented.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised to solve such a problem and to further improve the planting accuracy. Therefore, the seedling removal claws raise the potted seedlings taken out of the tray. In a vegetable transplanter configured to be able to open and transplant while lowering a hopper-type planting claw that can be received at a time, the pot-type seedling that is separated from the seedling removal claw is stopped at an ascending position. The planting claw is provided so as to be movable up and down so that the planting claw starts to descend before falling into the inward bottom portion.

[0005]

Therefore, when the pot seedlings taken out of the tray are separated from the seedling removal nails and fall into the inside of the planting nail stopped at the ascending position, they fall into the inner bottom of the planting nail. Before the planting claw starts to descend, the pot seedling does not float in the air and can follow the descending of the planting claw from the beginning, and in the hole created by the descending planting claw Can be transplanted with the pot seedlings standing upright, and can be planted with high planting accuracy.

3 and 4 schematically show a vegetable transplanter. An engine 3 and a transmission case 4 and a hydraulic pump 5 driven by the engine 3 are provided at the front of the body. The rear ends of both swing cases 6, 6 extending from both sides of the rear wheel 4, both rear wheels 7, 7 are respectively supported by shafts, and the front of both rear wheels 7, 7 are interlocked by hydraulic drive via interlocking mechanisms 8, 8. The front wheels 9, 9 which can be moved up and down together with the rear wheels 7, 7 are provided.
9 and a rear between the two rear wheels 7, 7 are equipped with a pressure-reducing roller 10 capable of rolling on the ridge B and both cultivation wheels 11, 11, respectively. A pot seedling a is provided in front of a handle 12 at the rear of the machine. The tray A seedling supply device 13 having the tray A is provided.
The seedling mounting table 14 on which the seedlings are placed is mounted on the drive mechanism 1 by the planting clutch case 17 transmitted from the transmission case 4 via the continuously variable transmission belt 15 and the planting timing rod 16.
The drive mechanism 18 is operatively connected to a seedling push-out pin 20 and is provided on both upper sides of a bonnet 21 with spare seedling mounts 22, 2.
2 are respectively provided and configured in the same manner as the conventional structure.

A hopper-type planting claw 2 is provided between the rear wheels 7, 7, and a seedling take-out claw 1 is provided above the front side of the seedling supply device 13. The seedling removal claw 1 is driven by the planting transmission case 23 that is operatively connected to the transmission case 4 to move up and down and open when lowered, as in the conventional case. 2, while taking out the pot seedlings a of the tray A by a rotary case 26 driven by a seedling picking claw drive wheel 25 interposed in the middle of a sprocket chain 24 transmitting to the mechanisms 18 and 19, as shown by an arrow A in FIG. It is configured to be drivable similarly to the conventional type so that the pot seedling a can be dropped downward by moving the pot seedling a. The planting claws 2 are provided so as to be able to move up and down so that the planting claws 2 start to descend before the seedlings a fall into the inner bottom of the planting claws 2 stopped at the rising position. I do.

Therefore, the seedling removal claw 1 is rotated as shown by the phantom line in FIG.
1 and 2, the pot seedlings a fall away from the seedling take-out nails 1 as shown by the arrow B while being separated from the seedling take-out nails 1, and stop inside the planted nails 2 at the ascending position. 1, the planting claw 2 starts to descend as shown by the arrow C before dropping into the inward bottom of the planting claw 2 as shown in FIG. a can follow the descent of the planting claw 2 from the beginning without floating in the air, and the pot seedling a stands upright in the hole formed by the planting claw 2 opened on the ridge B. Since the transplant is performed in the posture, the transplant can be performed with high precision.

[0009]

As described above, according to the present invention, when the pot seedling a taken out of the tray A separates from the seedling take-out claw 1 and falls into the inside of the planting claw 2 which is stopped at the ascending position, the present invention is not limited to this. The planting claw 2 starts to descend before falling into the inner bottom portion of the hopper-shaped planting claw 2, so that the pot seedling a does not float in the air as in the conventional type. It is possible to follow the descent from the beginning, so that the pot seedling a can be transplanted in a hole formed by the lowered planting claw 2 in an orderly manner while standing upright. It can be planted effectively with high planting accuracy without becoming a sardine seedling, and has a feature that can be suitably implemented.
