Description

[Detailed explanation of the idea] This invention relates to a rice transplanter.

When planting rice, determining the number of pine-shaped seedlings to prepare for the planned rice field has conventionally relied on experience and intuition, and when there are not enough pine-shaped seedlings, it is necessary to go back and collect pine-shaped seedlings midway through the work. Farmers face many practical problems, such as being forced to suspend production, or having to prepare a large number of seedlings in advance to avoid shortages, leaving a large number of pine-shaped seedlings left over. In particular, in recent years, the amount of seedlings to be taken out per plant and the planting interval have been changed depending on the variety of seedlings and the growth state at the time of planting, so even if the rice field is the same area, the pine-like The situation was such that the number of seedlings required changed, causing even greater confusion.

In view of the above points, the present invention enables the required number of pine-like seedlings for planting to be accurately and easily determined, regardless of changes in the amount of seedlings to be taken out depending on the variety of seedlings, etc. The purpose is to provide a rice transplanter that is extremely convenient in practice.

In order to achieve the above object, the rice transplanter according to the present invention has a first input part for means for changing and setting the distance between plants by changing the driving speed of the seedling planting device with respect to the running speed of the machine body, a seedling planting claw, and a seedling planting device. a second input unit for means for changing and setting the number of times the seedling planting claw takes out the seedlings by changing the relative driving speed with the mounting table; A third input section for the means for changing and setting the amount of seedlings taken out per one time by the claw, a fourth input section for the means for changing and setting the spacing between adjacent rows, and an area input section for inputting an arbitrary area; The present invention is characterized by being equipped with a mechanism that calculates and displays the required number of pine-shaped seedlings per required area based on set values input to each input section.

In other words, regardless of changes in plant spacing, changes in the number of times seedlings are taken out per one stroke of the lateral movement of the seedling stand, changes in the amount of seedlings taken out per plant, or changes in settings between adjacent rows, these changed settings can be input to the input section. By inputting , the required number of pine-shaped seedlings per required area will be calculated and displayed according to the area of the rice field and the remaining planting area during the work, so you can calculate and display the required number of pine-like seedlings in advance before starting the planting work. Regardless of the settings for changing the planting method, in other words, the settings for changing the planting consumption rate of pine-like seedlings, this can be determined depending on each setting.
Furthermore, even during work, by checking the actual amount used and the required number at an early stage, even if there is a shortage, the auxiliary worker can replenish the necessary number of pine-like seedlings and the work can be continued. We have now been able to provide a rice transplanter that is extremely convenient in practice and can avoid interruptions.

In the planting mechanism case 6, a speed change mechanism 15 is provided as a means for changing the number of seedlings to be taken out, which changes the lateral movement speed of the seedling platform 7 in two steps relative to the driving speed of the planting claws 11, and adjusts the width of the pine-shaped seedlings. The structure is such that the number of rotations of the planting claw 11 required to take out the seedlings over the entire width, that is, the number of times to take out the seedlings, can be changed in two stages, for example, 18 times and 26 times. .

The swinging arm 10 is planted in the planting case 6.
In order to pivot the swing arm 10, the pivot shaft 16 of the swing arm 10 is attached so that its position can be changed by rotating the screw member 14, and by changing the pivot position, the planting claw 11
Change the rotation locus of the planting claw 1 with one rotation.
The amount of seedlings taken out according to 1 can be changed, and the setting means for changing the amount of seedlings taken out is configured.

Attach the boss member 18 to the spare seedling stand at the front of the vehicle body.
18 is provided protrudingly, and a marker 19 is attached to each of the mounting boss members 18, 18 so as to be changeable between an upright non-use position and a horizontally fallen use position, and the marker 19 is attached adjacently by expansion/contraction and fixation. The distance between adjacent rows can be changed in three stages, for example, 28, 30, and 33 cm, and the means for changing the distance between adjacent rows is configured.

Below the handle 4, there are various means for changing the consumption rate of seedlings during the above-mentioned planting run, namely, a first means for adjusting the spacing between plants, a second means for changing the number of times seedlings are taken out, and a second means for changing the amount of seedlings taken out. 3 means and the 4th means for adjusting the distance between adjacent rows, respectively.
