Description

[0001] The present invention relates to an automatic distribution apparatus for liquid fertilizer,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic spreading apparatus, and more particularly, to an apparatus capable of automatically spreading slurry into an unmanned system within a narrow limited space such as a greenhouse and a greenhouse.

In general, the problem of environmental pollution is serious in the housing, and the problem of disposal of the manure caused by the excretion of the livestock becomes serious. In consideration of this, the liquid fertilizer is utilized for the effect of treating the manure according to the inclusion of the environmentally-friendly liquid fertilizer which is fermented by the excretion of livestock on the farmland, and the effect of forming the soil of good quality which gives the fertilizer .

Generally, when you want to spray liquid in the field of cultivated land in rural area, you use liquid dispenser.

In the past, a man used a liquid dispenser to spray a liquid dispenser back and forth, but this requires a lot of effort and time because an operator must spray the liquid dispenser while walking around the rice fields In addition, it has been pointed out that workers are forced to be exposed to sprayed liquid.

In order to solve the above-mentioned problems, a liquid dispenser is installed in a vehicle such as a tractor and sprayed on a field of rice. However, it is easy to spray liquid fertilizer while moving a vehicle equipped with a liquid fertilizer spreader in a large-sized field. However, in a place where a vehicle such as a greenhouse or a greenhouse is difficult to move, it is necessary to manually spray the liquid fertilizer .
