Description

Seed discharge roller with seeding control function {SEEDING ROLLER DEVICE HAVING FUNCTION OF ADJUSTING THE QUANTITY OF SOWED SEEDS}

The present invention relates to a seed discharge roller, and in particular, the seed discharge roller having a seeding rate adjustment function that can be arbitrarily adjusted according to the user's convenience to implement a variety of seeding methods such as sowing, point waves in a single seeding device It is about.

As a rule, sowing is made of mockup, fertilizer, cover with a little soil, and then seed. Afterwards, the soil was covered again to finish sowing. At this time, the reason for covering the soil after spraying the fertilizer is to reduce the chemical damage that can occur when the seeds are in direct contact with the fertilizer. This is to allow the growth of seeds from the harmful effects of rain and wind.

In recent years, the population of farming households has been gradually increasing due to the drastic decrease of rural population, but the working age actually participating in farming is gradually getting older. Therefore, various ways to realize the prolific work with a small labor force are being sought. One of the solutions is the spread of automated agricultural machinery.

The direct cultivation method is a method of planting and harvesting seeds directly in rice fields without growing them in the pond, and it is a new concept crop that can reduce the labor of workers according to seedling management and transplanting efforts, compared to the transfer method, which is currently used as a general cultivation method.
