Description

LIQUID MANURE INJECTING SYSTEM

The present invention relates to a manure spreader used in the application of livestock manure to the packaging in livestock farms, seedlings, etc., in particular to a manure injector to cut the soil and inject the manure into the soil.

As a means of recycling livestock manure, slurry of manure mixture is sprayed on farmland with liquid fertilizer. In spraying such liquid fertilizer on agricultural land, a conventional liquid diffusion spreader or a high-pressure spray liquid sprayer using the principle that the slurry is discharged and collided with the impingement plate is used.

Conventional liquor spreader is attached to the upper or lower portion of the liquid fertilizer tank connected to the tractor to spray the liquid fertilizer by high pressure. However, this method was uneven in spraying, and the odors caused by the spray spread to the atmosphere, and became a source of complaint.

In addition, the spread of the liquid fertilizer was inefficient because it remains on the surface of the soil, the fertilizer component is likely to be lost due to moisture evaporation by solar heat or washing by rainfall.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a liquid infusion system that can directly inject the slurry manure in the soil.

Another object of the present invention is to inject liquid fertilizer into the soil using the liquid fertilizer injection system to minimize the loss of fertilizer components, to suppress the generation of odor.
