Study on the Characteristics of Rotary Tillage

Abstract

For the purpose of study on the characteristics of the rotary tillage, we constructed a test car running on a soil tank.
The test car was driven by I/2_??_ single phase induction motor and the rotary shaft drived by 5_??_ three phases induction motor respectively, the rotary tines are used ordinary tine and flat knife tine (Natazume).
The speeds of the car and the rotary shaft are changeable, and the hardness and moisture of soils were maintained as possible as uniformly.
The results obtained may be summarized as follows:
1. The driving power of car was very little as compared wth the driving power of tine shaft.
2. When the tine shaft was slow revolution, the driving power per roll (Tan) was the most profitable, and increased hastily when the coefficient of breaking soil is under 200.
3. The tine shaft driving power was influenced by the soil hardness than the type of tines.
