Abstract

PROBLEM TO BE SOLVED: To provide the subject entirely satisfiable soil covering device. SOLUTION: This soil covering device is made up of a pair of soil covering means 11 towed by the transplanter behind a transplantation beak 8 and disposed so as to sandwich transplanted seedlings and a vibration-applying means 13 for applying vibratory motion onto the soil covering means 11 in a seedling transplanter designed to travel astride a ridge and transplant seedlings by the aid of mechanical power. This soil covering device has such an advantage that soil raking up is ensured by applying vibration onto the soil covering means 11, thereby enabling the roots of planted seedlings to be covered with soil to an entirely satisfiable state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling transplanter that runs across a ridge and transplants seedlings by power, and more particularly to a soil covering device that covers soiled transplanted seedlings.

[0002]

2. Description of the Related Art In a seedling transplanter which repeats an operation of receiving, piercing, and implanting seedlings prepared in a rotating seedling holding cup by a vertically moving transplanting beak, an apparatus for covering soil at the root of the seedlings implanted. Usually, the soil is scraped and covered with a plate-shaped or wheel-shaped means opened in a C-shape in the traveling direction or a plate-shaped means operated by opening and closing the transplantation cylinder.

[0003]

Heretofore, the type which opens in a U-shape in the traveling direction has been frequently used. However, since the covering is insufficient, the opening and closing operation of the transplanting beak is used. Various ideas have been devised, such as molds. However, none of them has been proposed to be insufficient and satisfactory. It is an object of the present invention to provide a completely satisfactory covering device for a seedling transplanter.

[0004]

In order to achieve the above object, a soil covering device for a seedling transplanter according to the present invention is arranged so as to run across a ridge and to transplant a seedling by power. And a pair of covering means arranged to sandwich the transplanted seedlings and a vibration applying means for imparting a vibrating motion to the covering means.

[0005]

With the soil covering device configured as described above, vibration is applied to the soil covering means towed behind the transplanting beak, so that the soil is reliably caught and excessively entered without being jumped up by pebbles or the like and slipping upward. It is completely satisfactory without excessive soil covering, and it is easy to adopt because it is only necessary to provide vibration adding means in a conventional device, and it is extremely useful.

[0006]

Embodiments will be described with reference to the drawings.
FIG. 1 is a front view of a seedling transplanter. An endless traveling device 2 is provided below both legs of a gate-shaped body 1 suitable for traveling across a ridge, and a hydraulic pump directly connected to an engine 3 is driven by a driving source. , And can be driven by a control device on the operation handle 4 and the operation panel 5.

[0007] The transplanting mechanism 6 is installed at the lower part of the vehicle body and supported by a seedling holding cup 7 rotatably supported around an upright shaft, and a transplanting beak 8 which can be moved up and down by appropriate means such as a cam or a link mechanism. Are provided. This transplant mechanism 6
During the operation of the cycle, the seedling holding cup rotates one pitch at a time to carry the seedlings sequentially to the supply position, and the transplanting beak 8 rises to receive the seedlings, descends and pierces the ridges, and drops the seedlings into the holes. The embedding operation is repeated, and is the same as that usually seen.

[0008] Behind the transplanting beak 8, a soil covering device is provided. A supporting rod 10 extending rearward from both sides of the transplanting beak 8 is pivotally attached to a part 9 of the frame of the transplanting mechanism 6, and has a front end extending in a C-shape toward the front in the traveling direction. A pair of covering soil rings 11 extending upward in a U-shape are pivotally supported. In other words, the soil covering ring 11 is towed behind the transplanter while holding the transplanted seedlings on both sides by their own weights and contacting the upper surface of the ridge, and covers the soil at the root of the seedlings.

A support plate 12 is fixed to the support rod 10 so as not to hinder the movement of the transplanting beak 8 and the rolling of the earth covering ring 11 so as to connect the support rod 10. 13 is fixed. In the present embodiment, a hydraulic vibrator connected to the hydraulic pump is used as the vibrator, and the vibrator imparts an oscillating motion to the earth covering wheel 11 at all times during operation of the transplanter. The covering soil ring 11 to which the vibration motion is applied, while rotating very smoothly, removes pebbles and the like, does not enter deeply, scrapes the soil on both sides, and covers the root of the seedling.

In this embodiment, the hydraulic pump is used as a driving source, so that a hydraulic vibrator that generates vibration by hydraulic pressure is used as the vibrator. However, the vibration is generated by another driving source, such as electricity or air. Needless to say, the means for generating can be used.

[0011]

By vibrating the soil covering means, the scraping of the soil is assured, and the root of the planted seedling can be completely covered with the soil.
