Description

[0001] Sand impurity removal device [0002]

More particularly, the present invention relates to an apparatus for removing impurities such as small stones or stones and small trash mixed in sand in a convenient and efficient manner by separating pure sand, stones, and impurities from each other , And a stone and impurity removing device mixed with the sand so that the sand surface is uniformly arranged.

As we all know, playgrounds, beaches, and sandy beaches on the banks of rivers are polluted by human waste, or waste from animals such as cats or dogs.

In the case of our country, the cleaning of the sandfield is still mostly dependent on the manpower. It is not so easy because it takes a lot of time and effort to clean the garbage in the sandbox with only the manpower.

In addition, it is easy to pick up conspicuous garbage dumped on the sand, but when garbage is buried in the sand, it becomes difficult to remove it if it is not visible.

Therefore, as mentioned above, it is difficult to collect garbage which is trampled and buried by people like a piece of gum, a bottle lid, a wooden chopstick, a piece of paper, a food waste, a coin, a key,

Because of that reason, there was a case where the garbage buried in the sand was neglected.

If we neglect the garbage that is buried in the sand, it is highly likely that we will make the sandfield unclean and infect the people who use it.
