堆肥埋込機の開発

その他

The majority of manure is spread on the field surface in a thin layer. This deposition technique leads to problems from runoff, undesirable order and most importantly a serious loss of the nitrogen content of manure because of exposure to the air. To avoid these problems, injection device of manure was developed.
At the field test, this device worked well and the manure pump pushed the manure into the furrow. But the piston period of manure pump unit required to match with the travel speed of tractor in order to push manure into the furrow continually. The pump unit also cannot arrange the injection volume of manure. To avoid these problems, This manure injector had better change injection unit from pump to auger.
In realization, 3 or 4 drills of this device will be located at the front end of a box type manure spreader, in which the travel direction of the web will be reversed to bring the manure to the front. The device should inject the manure at a spacing which corresponds to row crop spacing and if it could use at the same time with seeding device, a consideable reduction of production coat would be realized.
