Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for sowing soybeans, etc.

Recently, a method of using a rice transplanter for paddy rice to plow field crops such as soybeans and then transplanting them to somewhat dry paddy fields is becoming more and more popular. Because they are large and spread from side to side, if the seedlings are not sown in rows and raised in orderly rows, when the seedlings are scraped off during transplanting with a rice transplanter, the planting claws will damage the leaves or the leaves will be torn off, resulting in poor growth after transplanting. is significantly suppressed, causing a decrease in sales.

By the way, in order to sow yuzu such as soybeans in rows, the conventional method has been to use a row sowing machine to sow each row in a seedbed and then cover it with soil. However, it is difficult to produce seedlings in neat rows because they move irregularly during germination. Another method is to make a groove in the bed soil using a trenching tool, drop the soybean seeds into the groove, and then sow the seeds in the ridge soil. The grooves may collapse or soil may adhere to the groove-cutting tools, making it impossible to perform groove-cutting work smoothly and making work on the machine cumbersome.

Therefore, in the present invention, after the seedling raising box is filled on the floor, a large number of grooves are arranged in parallel at regular intervals on the seedling raising box, and a nine-row sowing machine is placed in one go to sow 1/% of the rows. Yuzu such as soybeans are inserted into the grooves of the vessel and positioned on the top surface of the bed soil, and then the protruding ridges are provided which can be freely inserted into and removed from each of the grooves and have a protruding length that is longer than the height of the grooves. By pressing the yuzu holder from above with the protrusions aligned with the grooves, the seeds on the bed are immersed in the casing at a predetermined depth inside the bed, which eliminates the need for conventional methods. Disclosed is a method for sowing soybeans, etc., which allows yuzu such as soybeans to always settle on the bed in a stable state, and also allows seedlings to grow in orderly rows of yuzu, from moths that can cause disrespectful work on the ground. The aim is to provide equipment.

An embodiment of the present invention will be described in detail with reference to the drawings. First, a seedling raising box 1 is filled with beds 2 to almost full, and then a row sowing machine 3 is placed on top of the seedling raising box 1. The seedling box mentioned above doubles as a fungus box for growing rice fungi, and the inner dimensions are, for example, 280mm.
It is 580 mm (width) x 30 mm (height). Furthermore, the row sowing device 3 is made up of a large number of row grooves 3/, 3/, etc. arranged in parallel at predetermined intervals, and the depth of the row grooves 3' is approximately the same as one dog bean. The grains are arranged one by one along the grooves 3 at corresponding depths. The illustrated example is made by superimposing upper and lower two-stage plate bodies 3a and 3b in which grooves 3, 3', etc. are arranged in parallel at the same pitch, and as shown in the figure, the lower plate body 3a Although it is slidably fitted into the upper plate 3a or the lower plate 3b via the guide rail 4, it may be only the upper plate 3a or the lower plate 3b.

After placing the row wT holder 3 on the seedling growing box 1 as described above, as shown in FIG. Seeds 5, such as soybeans, are inserted into the grooves 3' of the upper plate 3a with the upper plate 3a closed. Then, if the upper plate body 3a is shifted in the opposite direction to the above and the upper and lower grooves 3/ and 3/ are brought into communication with each other, the seeds 5
falls into the groove 3' of the lower plate 3b and is positioned and supported while being in contact with the upper surface of the floor 2. In this state, the yuzu holding tool 6 is used to push the seeds 5 on the bed to a predetermined depth. This Miko holding tool 6 is provided with protrusions 6/, c, /... that can be inserted into and removed from each of the above-mentioned grooves 3', and the protrusion length t of each protrusion 6' body 3a,
The overlapping height H of the strips 37 and 3/3 provided on the upper and lower plates 3a, respectively.

It is set so that h is the same as the total wall thickness of 3b).

The amount of soil to be covered with soil can be arbitrarily changed by changing the dimension of this h as appropriate and changing the depth of pushing the seeds 5 onto the bed.

The protruding end surface of the protrusion 6' is formed into a curved surface 67a roughly drawn around the outer periphery of the soybean seeds 5, as shown in FIGS. 3 and 6, and pushes the seeds 5 into the bed 2. At this time, if the soybean seeds 5 are pushed downward with the protrusions 6' aligned with the grooves 3', the soybean seeds 5 are held from above by the curved surfaces 6'a at the lower ends of the protrusions 6'. The device can be reliably immersed to a certain depth in the same state (see Figure 3).

5-A After pushing the seeds 5 into the bed soil 2 using the seed presser 6 as described above, if the rod presser 6 is removed, the rotation of the seeds 5 will easily collapse due to vibration etc. This has the same effect as creating a channel over the seeds 5 and covering them with soil.

In addition, during the subsequent irrigation, the soil around the pushed seeds 5 collapses evenly, so the horizontal raising work that was previously required is completely unnecessary, which not only greatly simplifies the row sowing work, but also allows the seeds 5 to be spread in rows. It forms a strip and reliably lands on the floor ±2. Therefore, it is possible to grow seedlings in nine rows in an orderly manner.

As mentioned above, in the present invention, after filling the seedling box with bed soil,
A row sowing machine with a number of rows arranged in parallel at predetermined intervals is stacked on top of a seedling nursery box, and seeds such as soybeans are inserted into the grooves of each row sowing machine and positioned on the upper surface of the bed. Next, a seed holding tool, which is removably inserted into the groove and has a protruding length larger than the height of the groove, is pushed in from above with the protrusion aligned with the groove. Since the seeds on the bed soil are immersed to a predetermined depth inside the bed soil, the horizontal raising work after sowing, which was conventionally required, is no longer required, which greatly simplifies the work and reduces labor. It is possible to ensure that yuzu such as soybeans always settle in the bed soil in an orderly row in a stable state, thereby making it possible to obtain soybean seedlings, etc. in orderly rows. This has the effect of making it possible to more accurately and easily transplant soybean seedlings using a rice transplanter.
