Description

Mixer truck with snow removal {Mixer truck for clearing snow from the road}

The present invention relates to a mixer truck having a snow removal function, and more particularly, to a mixer truck having a snow removal function, which is capable of removing roads by mixing and spraying a solid snow removing agent and a liquid snow removing agent as necessary. .

To remove snow accumulated on the road in winter, a solid (or granular) snow remover such as calcium chloride, sodium chloride or magnesium chloride and sand are applied alone or in combination to the road.

The snow remover applied to the road in this way reacts with water to generate heat, thereby melting snow. Moreover, the water melted and converted again reacts with the snow remover to generate heat, which continuously melts the snow. In addition, the water in which the snow remover is dissolved does not freeze even when the temperature is lowered by freezing.

As described above, since the snow removing agent reacts with water, it is preferable to apply a liquid snow removing agent for rapid snow removal. In this case, when the snow removal agent and water are mixed in advance, the reaction heat does not act to melt snow on the road, and thus, a liquid snow removal agent and a solid snow removal agent must be mixed and applied immediately before being sprayed on the road.

In addition, the sand applied to the road serves to reduce friction of the vehicle by acting as a friction material.

However, the conventional snowplow spreading vehicle is spraying a solid snowplow of a predetermined width and amount on the road at a uniform speed in the loading box, or spraying a liquid snowplow using a watering wheel or the like.

In this case, when the liquid snow removing agent is sprayed by the above method, since the liquid snow removing agent that wastes the reaction heat in which the solid snow removing agent reacts with water is sprayed on the road, there is a problem in that the snow removing effect is not large.

In addition, when spraying the solid snow removing agent in the above method can not control the spreading range, if the spraying snow removing agent in a narrow area has a small snow removal effect and when spraying widely, there is a problem to kill the surrounding trees or to corrode the facilities. .

In addition, conventional snowplow spraying vehicles cannot control the amount of snowplow, so when the vehicle travels at a high speed, the amount of snowplow applied is insufficient and snowplowing is not performed properly. Excessive snow removal will lead to unnecessary waste.

In addition, the conventional snow removal vehicle has a problem that can not actively cope with the snow-covered form of the road because it can not adjust the mixing ratio of the snow removal agent during the spraying.

The present invention has been made to solve the above problems,

The purpose of the present invention is to provide a mixer truck having a snow removal function that allows snow to be quickly removed because the solid snow and the liquid snow remover are mixed in real time and sprayed on the road. have.
