Description

[Detailed description of the invention] Industrial application field This invention is a sweet potato seedling transplanter that can orderly plant sweet potato seedlings supplied to the transplanter in a predetermined planting posture as the machine moves. This is related.

BACKGROUND ART 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 that the present invention aims to solve In general, sweet potato seedlings can be planted horizontally, in which the seedlings are transplanted horizontally, in a boat bottom, as well as diagonally.
There are many types of upright planting, but in particular, so-called boat-bottom planting, in which the center of the seedling is planted in a boat-like planting position, is slightly deeper.
It is widely used because it requires less planting and the seedlings take root well.

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-shaped manner by deepening the central part of the seedlings, and the seedlings must be planted by hand. Because they were planted in the shape of a boat bottom, the transplanting work was difficult and had the disadvantage of poor work efficiency.

The present invention was devised in order to solve these problems in view of the above-mentioned actual situation.The present invention is designed to solve these problems by simply allowing the transplanting body to hold the sweet potato seedlings while the aircraft is running. The purpose of the present invention is to provide a sweet potato seedling transplanter that can automatically plant seedlings in a predetermined planting posture.

Means for Solving the Problems In order to achieve the above object, the technical means taken by the present invention is to provide a rotating shaft in the aircraft frame that rotates in conjunction with the movement of the aircraft, and the rotating shaft has a plurality of motors. In a sweet potato seedling transplanting machine in which the plants are arranged radially and the sweet potato seedlings held in the transplanting body are implanted as the machine moves, a seedling feeding device formed on the outer surface of the transplanting body is provided. A sweet potato seedling root clamping part is provided on the surface at the front end in the rotational direction of the transplanting body, and a leaf tip clamping part is provided at the rear end in the rotational direction to clamp the sweet potato seedling vines along the seedling supply surface. In addition, the present invention is characterized in that the clamping of sweet potato seedlings by both clamping parts is released at the planting position.

Function of the invention Next, the function of the invention configured as described above will be explained. When transplanting sweet potato seedlings, first the aircraft is driven, and the rotating shaft installed in the aircraft frame rotates in conjunction with the movement of the aircraft. Next, if the roots of the sweet potato seedlings are held between the root holding parts provided on the seedling feeding surface of the transplanting body disposed on the rotating shaft, the root holding parts are provided on the front end side in the direction of rotation of the transplanting body.
Sweet potato seedlings are supported along the seedling supply surface by rotation of the transplanting body. The sweet potato seedlings are held along the seedling supply surface because the leaf tips of the sweet potato seedlings are held by the leaf tip clamping portion provided on the rear end side of the seedling supply surface in the rotational direction of the transplanting body. When the transplanting body further rotates and reaches the lower planting position, the clamping by the two clamping parts is released, the transplanting body rotates upward from the lowest position, and the sweet potato seedlings are planted in a predetermined posture. be able to.

Embodiment The structure of the present invention will be explained based on the embodiment shown in the drawings. Reference numeral 1 denotes a fuselage frame equipped with a front wheel 2 and a rear wheel 3, and an engine 4 mounted at the rear. , a rotating shaft 5 is provided in the width direction of the fuselage frame 1, located between the front wheels 2 and the rear wheels 3. The rotating shaft 5 connects a drive shaft 6 of a transmission mechanism that transmits the power of the engine 4 to the rear wheels 3, a pulley 7,
8. It is driven via a chain 9, and rotates in the same direction as the rear wheels 3 in conjunction with the travel of the aircraft.

Reference numeral 10 denotes a plurality of mounting arms projecting radially from the rotating shaft 5, and the mounting arm 10 has parallel links consisting of connecting arms 13 and 14 pivoted to support shafts 11 and 12 on the distal end side thereof. A transplanting body 15 is attached to each via a mechanism, and the said transplanting body 15 is arranged concentrically with the rotating shaft 5 by the bias of a spring 16 stretched between it and the mounting arm 10. A roller 18 is attached to the cam surface 17a of the cam body 17.
It is held in a compressed manner through the . Also, cam body 1
7 includes a transplanting body 15 that rotates concentrically with the rotating shaft 5.
A straight portion 17b is formed to guide the plant from the vicinity of its lowermost position toward the rotating shaft 5 side, and the outer surface of the transplanting body 15 is formed into a curved shape to guide the vines of the sweet potato seedlings a. The running locus near the lowest position of the seedling supply surface 15a, which is held together, is shaped like the bottom of a boat (see FIG. 6).

Reference numeral 19 denotes a root holding part made of an elastic body provided on the front end side of the seedling supply surface 15a in the rotational direction of the transplanting body 15, and a spring 21 installed in the rod 20.
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 rotates in contact with a cam piece 23 attached to the cam body 16, pulls up the rod 20, and releases the root clamping of the seedling by the root clamping part 19. Also, seedling supply surface 15
A leaf tip holding part 26 made of an elastic piece 25 having a sponge body 24 attached to opposing surfaces facing each other with a predetermined gap is provided at the rear in the rotational direction of a. In this case, the transplanting body 15 is connected to the rotating shaft 5.
While rotating from the upper side to the lower side, the elastic piece 25 is pressed from both sides by the guide body 27 disposed concentrically with the rotating shaft 5, and the root part is held between the sponge bodies 24 by the root holding part 19. Hold the tip of the leaf of the sweet potato seedling. When the planting body 15 rotates to the lower planting position, the elastic pieces 25 separate from the guide body 27 and expand to release the grip on the leaf tips.

28 is a boring tool that moves up and down in conjunction with the rotating shaft 5 to open a planting hole in the mulch sheet b, and 29 penetrates into the soil before the root holding part 19 during planting to prevent damage to the seedlings. The leading rod 30 is a seedling guide attached to both sides of the seedling supply surface 15a. Further, 31 is a cleaning brush for the seedling supply surface 15a, 32 is a driver's seat, 33 is a soil covering wheel, 34 is a clutch pedal, and 35 is a headland turning handle.

In the above configuration, when transplanting sweet potato seedlings, if the seedling transplanter is positioned across the ridge so that the transplanting body 15 faces the ridge and runs along the ridge, the rotation axis The transplanting body 15 attached to the mounting arm 10 protruding from the machine body 5 rotates in the direction of arrow A in conjunction with the traveling of the machine body. Next, if the driver sitting in the driver's seat 32 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 sweet potato seedling a will be removed as the transporting body 15 rotates. The trunk takes a posture along the curved seedling supply surface 15a while being supported by the seedling guide 30 on both sides, and when the leaf tip holding part 26 reaches the guide body 27, the sponge body 24 of the elastic piece 25 pressed from both sides The tip of the leaf is held between them, and the sweet potato seedling a is held in a stable curved posture along the seedling supply surface 15a, as shown in FIG.

When the transplant body 15 further rotates downward, the transplant body 15
enters the soil while holding the sweet potato seedlings a, but the roller 18 is guided by the straight portion 16b of the cam body 16 from near the lowest position, and the seedling supply surface 15a draws a running trajectory in the shape of a boat bottom. Further, the pulling arm 22 that rotates in contact with the cam piece 23 releases the root grip of the root grip part 19, while the leaf tip grip part 26, which has separated from the guide body 27, releases the grip on the leaf tip and then transports the leaf. Since the body 15 rotates upward, sweet potato seedlings a whose root and leaf tips are released can be planted in an orderly boat-like shape (see Fig. 7).

In addition, when the transplanting body 15 enters the soil, the leading rod 29 first enters the soil, so the roots of the sweet potato seedlings a are not damaged by the impact of the soil, and the mulch sheet b is used to prevent the roots from being damaged by the impact of the soil. Even when the planting hole is covered, the planting hole can be opened automatically using the punching tool 28 that is linked to the rotating shaft 5.

Effects of the invention In short, the present invention provides a rotating shaft that rotates in conjunction with the traveling of the aircraft on the aircraft frame, a plurality of transporting bodies are arranged radially on the rotating shaft, and
In the sweet potato seedling transplanter which is configured to implant the sweet potato seedlings held in the transplanting body as the machine moves, the seedling supply surface formed on the outer surface of the transplanting body has a front end in the rotational direction of the transplanting body. A part to hold the roots of sweet potato seedlings is provided on the side.
A leaf tip clamping part is provided on the rear end side in the direction of rotation to clamp the sweet potato seedling vines along the seedling supply surface, and the clamping part is configured to release the sweet potato seedlings from being clamped at the planting position. Therefore, if the root part of the sweet potato seedlings is held between the root holding parts provided on the seedling supply surface of the transplanting body disposed on the rotating shaft, the sweet potato seedlings will be supported along the seedling supply surface by the rotation of the transplanting body. Since the leaf tip portion is held by the leaf tip holding portion provided on the rear end side of the seedling supply surface in the direction of rotation of the planter, the sweet potato seedlings can be held in a shape along the seedling supply surface. When the planting body further rotates and reaches the lower planting position, the clamping of the two clamping bodies is released and the sweet potato seedlings can be planted in a predetermined posture. This method has extremely useful practical effects, such as the ability to efficiently plant sweet potato seedlings by simply holding the sweet potato seedlings one after another between the plants, and the efficiency of transplanting work can be significantly improved. be.
