Description

[Detailed description of the invention] Industrial application field This invention is designed to neatly plant sweet potato seedlings supplied to a transplanter into a ridge covered with a mulch sheet in a boat-like planting position as the machine moves. This relates to a sweet potato seedling transplanter that can be used for planting.

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 using horizontal planting, boat-bottom planting, diagonal planting, and upright planting. The so-called boat-bottom planting method, in which the seedlings are planted in a vertical position, is widely used because it requires less planting and the seedlings take root better.

However, with conventional transplanters that simply pinch the base of the seedling with a pair of clamping claws and insert it into the soil, it is not possible to plant the seedling deep in the center of the seedling in a boat-shaped shape. It is being planted. Particularly when planting in a ridge covered with a mulch sheet, the planting holes must be opened in advance, which makes the work troublesome and has the drawback of poor efficiency in the transplanting work.

The present invention was devised in order to solve these problems in view of the above-mentioned actual situation.While the machine is running, the planter can simply hold the sweet potato seedlings in the planting body, and the plant can be planted in the ridges covered with mulch sheets. The purpose of the present invention is to provide a sweet potato seedling transplanter that can automatically plant seeds in a boat-shaped planting position.

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 travel of the aircraft, and the rotating shaft has a plurality of In a sweet potato seedling transplanting machine in which the transplanting bodies are arranged radially and the sweet potato seedlings held in the transplanting bodies are planted as the machine moves, the machine body has perforations in a mulch sheet that covers the ridges. The tool is attached facing the front of the transplanting body so that it can move up and down, and the punching tool is moved up and down intermittently in conjunction with the rotation of the transplanting body, and the sweet potato seedlings are inserted into the openings of the mulch sheet that have been punched in advance. It is characterized by being implanted with.

Function of the invention Next, the function of the invention configured as described above will be explained. Now, when transplanting sweet potato seedlings, if you hold the sweet potato seedlings in the transplanting body installed on the rotating shaft while the machine is moving, the sweet potato seedlings will be planted by the transplanting body that rotates as the machine moves. can be included. Then, the perforator on the mulch sheet, which is attached so that it can move up and down facing the front of the transplanting body, moves up and down intermittently in conjunction with the rotation of the transplanting body, and plants the sweet potato seedlings at predetermined positions on the mulch sheet. Since the holes are automatically drilled in advance, there is no need to manually open the mulch sheet and the transplanting work can be carried out efficiently.

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 lowermost position of the seedling supply surface 15a, which is held together, forms a boat bottom shape.

Reference numeral 19 denotes a root holding part for seedlings made of an elastic body provided at the front in the rotational direction of the seedling feeding surface 15a, and is normally pushed out toward the outside of the transplanting body 15 by a spring built into the rod 20. Retained. 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 17, pulls up the rod 20, and releases the root clamping of the seedling by the root clamping part 19. Further, at the rear of the seedling supply surface 15a in the rotational direction, a leaf tip holding part 25 is provided, which is made of an elastic piece 24 having a sponge body attached to opposing surfaces with a predetermined gap. Clamping part 2
