Conventionally, to sow seeds such as beans, radishes, sweet potatoes, and potatoes, a method was used to sit in the field using a hoe or hoe to dig up the ground, put the seeds in, and then cover the soil again. In case of mass cultivation, sowing was used. There was a problem in that it took a lot of time and effort to sow seeds when laying plastic on the field and sowing the seeds in the multiple holes made in the same manner as above.

Meanwhile, although a seed sowing device has been designed to sow seeds, it is inconvenient to sow seeds in the field by holding the body of the seed sowing device with one hand and pressing the handle with the other hand, making continuous work impossible, and losing seeds. There are many problems where the effect does not meet expectations.

Recently, various types of seeders have been used that have a structure that covers and compacts the soil after sowing the seeds.

Here, the seeding machine can be divided into a manual seeding machine, which sowing by human labor, and an automatic seeding machine, which sowing automatically using a self-installed motor or engine. Both have seed supply rollers with a number of seed grooves of different sizes on wheels. It is configured to be connected to the drive shaft and rotate, and the seeds are stored in the seed storage bin at the top, and as the seed supply roller rotates, they are placed in the seed groove and transferred to the lower part. They move to the lower part through the transfer pipe, fall into the furrow dug by the plow, and then fall into the furrow dug by the plow. The soil cover plate covers the furrow and the compaction roller is configured to compact it.

However, the conventional seeding machine has a problem in that seeds are intermittently not accommodated in the seed-receiving groove of the seed supply roller, resulting in irregular seeding intervals, and there is also a problem in that the seed-receiving groove is blocked by soil flying from the ground, preventing sowing.
