堆肥埋込機開発のための基礎実験(2) : バーク堆肥による堆肥投入装置の性能

A solid manure injection system is a benifical method which preserves manure nitrogen and reduces undesirable odor and pollution problems. This system design consists of two basic units which are a furrow opener and auger conveyer of manure.
The manure which was first tested in the auger unit was bark of broad-leaved tree. This material did not work into the auger unit readily, therefore, did not allow it to work. To solve this problem, in this paper, the tests were tried with lieqid(moisture content 78%) and dry condition of bark mnanure.
The injection volume per required torque of auger shaft in liquid condition of manure, was much as compared with dry condition when the revolution speed and the angle of auger shaft were relatively small, and was less when they were large. The efficiency of auger unit was high in liquid condition when the area of feed inlet port of auger conveyer was relatively small.
From test results, in liquid condition of manure, the injection divice of auger unit can be applid with less required torque of auger shaft by using 45゜in angle and relatively small feed inlet port.
