Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sweet potato seedling transplanter that can orderly plant sweet potato seedlings in a predetermined planting posture as the machine moves.

BACKGROUND TECHNOLOGY Conventionally, as a transplanting machine used when transplanting sweet potato seedlings, there is a known one that uses tweezers-like clamping claws to pinch the base of the sweet potato seedling and insert it into the soil.

Problems to be Solved by the Invention In general, methods for planting sweet potato seedlings include horizontal planting in which seedlings are transplanted horizontally, boat bottom planting, diagonal planting,
There are various methods of planting, such as upright planting, but the so-called boat-bottom planting, in which the center of the seedling is made slightly deeper and planted in a boat-like planting position, is widely used because it is less likely to be planted and the seedlings take root well. ing.

However, with conventional transplanters that simply pinch the base of the seedlings with their clamping claws and insert them into the soil, it is not possible to plant the seedlings in a boat-like shape by deepening the center of the seedlings. This was done manually, which required a great deal of labor and had the disadvantage of poor work efficiency.

The present invention was devised in order to solve these drawbacks in view of the above-mentioned actual situation. The purpose of this invention is to provide a sweet potato seedling transplanter that can plant sweet potato seedlings in an orderly manner.

Means for Solving the Problems The technical means taken by the present invention to achieve the above object is that a rotating shaft that rotates in conjunction with the traveling of the aircraft is provided in the aircraft frame, and a predetermined plant is attached to the rotating shaft. By radially arranging a plurality of implants configured in a fixed shape,
The present invention is characterized in that the sweet potato seedlings held by the planting body are planted in a predetermined planting posture as the machine moves.

Effects of the Invention The effects of the present invention configured as described above will be explained. Now, when transplanting sweet potato seedlings, if the transplanter is run, the rotating shaft provided in the machine frame will rotate in conjunction with the machine's running. If the sweet potato seedlings are held in the radial transplanting body arranged on the rotating shaft, it is possible to plant the sweet potato seedlings in a predetermined planting posture by the transplanting body that rotates as the machine moves. If sweet potato seedlings are sequentially supplied to the machine, the sweet potato seedlings can be planted in a predetermined planting posture in an orderly manner simply by driving the machine.

Each transplanting body 15 is attached via a mechanism, and the transplanting body 15 is attached to a cam body disposed concentrically with the rotating shaft 5 by a spring 16 stretched between it and the mounting arm 10. The cam surface 17a of 17 is biased and supported via a roller 18. The cam body 17 has a transplanting body 15 that rotates concentrically with the rotation shaft 5, and the cam body 17 suddenly rotates the rotation shaft 5 from the vicinity of the lowermost position.
A straight line portion 17b is formed to guide the sweet potato seedlings a toward the side, and the running trajectory of the curved seedling supply surface 15a that holds the central portion of the sweet potato seedlings a formed on the outer surface of the transplanting body 15 is As shown in Figure 6, the plants are planted in a predetermined posture, for example in the shape of a boat bottom. Reference numeral 19 denotes a seedling root holding portion made of an elastic body provided on the front side in the rotational direction of the seedling feeding surface 15a, and is a seedling root holding portion made of an elastic body.
It is normally held in an extruded shape toward the outside of the transplant body 15. One end of a lifting arm 22 pivotally connected to the transplanting body 15 is locked to the rod 20, and when the transplanting body 15 is rotated to the lower planting position, the other end of the lifting arm 22 is It contacts the cam piece 23 and rotates, and the rod 20 is pulled up, the root clamping part 19 is retracted, and the root clamping of the seedling is released.

Further, on the rear side of the seedling supply surface 15a in the rotational direction, a sponge body 24 is provided on the opposing surface facing with a predetermined gap.
A seedling leaf tip holding part 26 is provided which is made of an elastic piece 25 to which is attached. While the transplanting body 15 rotates from above to below the rotation shaft 5, the leaf tip holding portion 26 is pressed from both sides by the guide body 27 arranged concentrically with the rotation shaft 5, and the sponge body 24
The leaf tips of the seedlings are held between them, and the transporting body 15 is attached to the rotating shaft 5.
When rotated to the lower planting position, the leaf tip holding part 26
The leaf tip is detached from the guide body 27 to release the grip on the leaf tip.

Reference numeral 28 denotes a punching tool for the multi-sheet b, which is attached to the aircraft frame 1 facing forward of the transplanting body 15, moves up and down in conjunction with the transplanting body 15, and inserts sweet potato seedlings a into the multi-sheet b. Drill implant holes at predetermined intervals.

29 is a seedling guide attached to both sides of the seedling supply surface 15a, 30 is a rotary seat, 31 is a cleaning brush for the seedling supply surface 15a, 32 is a soil cover ring, 33 is a clutch pedal, 34 is a headland turning handle, 35 is a leading round bar provided in front of the root holding part 19.

In the above configuration, when transplanting sweet potato seedlings, one transplanted body is placed on the ridge where the sweet potato seedlings are to be planted.
If you run the seedling transplanter along the ridge in a posture that straddles the ridge between the left and right wheels of the front wheels 2 and the rear wheels 3 so that the front wheels 5 are facing, the seedling transplanter will hit the rotating shaft 5 that rotates in conjunction with the running of the machine. A transplant body 1 attached to a mounting arm 10 provided

If the driver sitting in the position 0 holds the root part of the sweet potato seedling a with the root holding part 19 of the transplanting body 15 which has been rotated to the upper position, the central part of the seedling will move as the transporting body 15 rotates. While being supported by the seedling guides 29 on both sides, it assumes a posture along the curved seedling supply surface 15a, and the leaf tip holder 2
When the seedlings 6 reach the guide body 27, the leaf tips of the seedlings are clamped by the sponge bodies 24 of the elastic pieces 25 pressed from both sides, so that the sweet potato seedlings are moved along the seedling supply surface 15a as shown in FIG. It is held in a stable curved posture.

When the transplant body 15 further rotates downward, the transplant body 15
The roller 18 plunges into the soil while holding the sweet potato seedlings a, but from near the lowest position, the roller 18 is guided by the straight part 17b of the cam body 17 and suddenly approaches the rotating shaft 5 side, causing the running of the seedling supply surface 15a. The trajectory becomes a boat bottom shape. Then, the pulling arm 22 that rotates in contact with the cam piece 23 pulls up the rod 20 and releases the grip of the root gripping part 19, and the leaf tip gripping part 26 that has separated from the guide body 27 releases the gripping of the leaf tip. Since the planting body 15 rotates upward, the sweet potato seedlings a can be planted in an orderly manner in the shape of a boat bottom as shown in FIG. can be improved. Furthermore, at the time of planting, the leading round rod 35 plunges into the soil first, so the root part of the sweet potato seedling a is not damaged, and even if the ridge to be planted is covered with the mulch sheet b, it is linked to the planting body 15. The planting hole can be punched automatically with the punching tool 28.

Effects of the Invention In summary, the present invention provides a rotating shaft that rotates in conjunction with the traveling of the aircraft body on the aircraft frame, and a plurality of planting bodies configured in a predetermined planting shape are arranged radially on the rotating shaft. Since the sweet potato seedlings held by the transplanting body are planted in a predetermined planting posture as the machine moves, the sweet potato seedlings can be held by the radial planting body disposed on the rotating shaft. For example, it can be planted automatically without any manual work, so it is easy to feed sweet potato seedlings to multiple planting bodies one after another while the machine is running, and the desired planting posture can be achieved. The plant can be planted in an orderly manner and has an extremely useful new effect that can significantly improve the efficiency of the planting work.
