DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a fertilizer that is fed into a fertilizer hopper of a fertilizer spreader when the fertilizer is sprayed by the fertilizer spreader, for example, a nitrogen fertilizer, a phosphate fertilizer, and a kari fertilizer. The present invention relates to a fertilizer mixing apparatus for feeding a predetermined amount of each of them into a desired mixing ratio, stirring and mixing them, and adjusting and preparing the compound fertilizer.

[0002]

2. Description of the Related Art Conventionally, when a fertilizer is applied to a field using a fertilizer spreader, a fertilizer mixing apparatus for adjusting the fertilizer to be applied to a fertilizer hopper of the fertilizer spreader in advance and to adjust the fertilizer in advance is known. In, facilities are fixed and installed in a fixed place such as a work building as a facility, or, while mixing a small amount of fertilizer into the fertilizer hopper of the fertilizer spreader, or while stirring and mixing There are only small ones that are built into the fertilizer spreader as they are being spread.

[0003]

In the former fertilizer mixing apparatus, which is installed in a certain place as the former facility, the adjusted fertilizer is fed into a fertilizer hopper of a fertilizer spreader, and is fed to a field. When spraying, every time you have finished spreading the fertilizer in the fertilizer hopper of the fertilizer spreader, be patient with the trouble of having to move the fertilizer spreader between the facility and the field, or separately from the facility. There is a problem that a transport vehicle for transporting the adjusted fertilizer to the field must be prepared.

[0004] Even if a transport vehicle is prepared, when the fertilizer is fed from the transport vehicle into the fertilizer hopper of the fertilizer spreader,
Another problem comes with cumbersome work.

[0005] In the latter small fertilizer mixing device incorporated in the fertilizer spreader, since the processing capacity for mixing the fertilizer is small, when a large amount of fertilizer is sprayed over a wide field, the fertilizer is mixed. There is a problem that the time required to adjust the compound fertilizer decreases the efficiency of the fertilizer spraying operation, and also transports the single element fertilizer before mixing and adjusting to the field. The problem of needing a car comes up.
