Description

Electric seed seeder with a seated chair {ELECTRIC SEEDING MACHINE WITH A CHAIR}

The present invention relates to an electric seed sowing machine having a seated chair. More specifically, the present invention relates to an electric seed sowing machine that can sow seeds while riding on a seated chair, enabling sowing of seeds over a long period of time. In addition to minimizing noise and vibration when sowing garlic, a plurality of seed sowing units are installed in a row, and each seed sowing unit has a sitting chair that allows automatic sowing of seeds and simultaneous planting and covering. It is about an electric seed seeder.

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 seeds the seed automatically using a self-installed engine. In both cases, the seed supply roller, which has a number of seed grooves of different sizes, is driven by the driving shaft of the wheel. It is configured to be connected and rotated, 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 are subsequently covered with soil. The 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.

In addition, since conventional seed drills use an engine as the main power source, there is a problem in that seeds are not seated in the seed receiving groove of the seed supply roller due to vibration of the engine.

In addition, the conventional seed sowing machine had the problem of not being able to sow seeds over a long period of time because the operator had to sow seeds while moving while holding the handle.

It can be configured to receive rotational power, and more preferably, since a relatively high number of rotations is required, a separate drive motor (not shown) can be fixed to the side frame 200 to receive rotational power. .

In this configuration, when the camshaft 454 rotates, the lifting plate 451 in contact with the cam 455 is raised and lowered by the spring 453, so that the cleaning brush 450 is raised and lowered to the circle of the seed supply roller 420. It is configured to clean the main surface and the interior of the first seed receiving groove (421).

Therefore, when the first seed receiving groove 421, from which the seeds have escaped, re-enters the seed storage container 410, it can be maintained in a clean state without being clogged by soil, making it possible to provide a structure that can continuously supply seeds.

In another embodiment, the cleaning brush 450 may be composed of two. Each of these cleaning brushes 450 may be provided with two camshafts 454 so that they can be alternately raised and lowered (not shown).

It may be configured to be equipped with a fixing lever 461 for fixing it.

The covering plate 472 is elastically installed on the covering plate 470 to cover the seeding bone formed by the covering plate 470, so that each seed sowing unit 400 independently forms a seeding bone, and sowing seeds. The process of sowing and covering the seeded seeds can be processed in one batch.

In addition, each seed sowing unit 400 is an independent entity and can be easily replaced and expanded in the electric seed sowing machine 500 with a seat, making maintenance very convenient.

In addition, since each of the seed sowing units 400 is integrally connected with the topsoil plate 470 and the topsoil plate 472, a larger number of seed sowing units 400 can be installed compared to the overall size of the electric seed seeder with a sitting chair. You can install it.

Hereinafter, the operation of the electric seeding machine according to the present invention will be briefly described with reference to FIG. 13.

First, when the user rotates the motor (M) using the control panel 112, the motor (M) rotates the rear compaction roller (300a) connected to the reducer (120) and the chain (C).

At the same time, when the rear wheel compaction roller (300a) rotates, the front wheel compaction roller (300a) receives power through the belt (B) and rotates.

Then, like a four-wheeled vehicle, power is transmitted to the front wheel compaction roller 300a and the rear compaction roller 300a, allowing smooth driving even on highly curved ground.

And the drive shaft 233 is connected to the front wheel compaction roller 300a and the chain (C) and rotates, and each seed sowing unit 400 has a driven gear 424 engaged with the drive gear 233a connected to the drive shaft 233. ) to rotate the seed supply roller (420).

Then, among the seeds stored in the seed storage container 410, the seeds accumulated in the seed groove 422a of the seed supply roller 420 are received in the first seed receiving groove 421 as the seed supply roller 420 rotates.

In this state, when the seed supply roller 420 rotates clockwise, the seeds accommodated in the first seed receiving groove 421 enter the inside of the elastic plate 432 through the selection brush 440, and the first seed Due to the interference of the sorting brush 440 that is not accommodated in the receiving groove 421, it is prevented from entering the inside of the elastic plate 432.

The seeds that have entered the inside of the elastic plate 432 are guided until they approach the ground without leaving the first seed receiving groove 421, and fall into the seeding groove formed by the topsoil plate 470, where the seeds are sown. The valley is covered by the covering plate 472.

Here, the first seed receiving groove 421, from which the seeds are released, is cleaned without being clogged by the soil because the soil scattered and adhered to the ground is removed by the washing brush 450, which is raised and lowered before re-entering the seed storage container 410. By maintaining this condition, seeds can be supplied continuously.

Meanwhile, the ground is leveled before sowing the seeds through the front wheel compaction roller (300a) to induce the formation of the seed bone at a balanced depth before the seed bone is formed, and the seed bone covered with soil is formed through the rear wheel compaction roller (300a).
