In order to save power and use fuel more efficiently,the relationship between the rotator s traction power coefficient and the rotator width was studied in this article.

Technology Research and Trial of Rotary Tillage and Bury-Stalk;

Experiment modeling method was used to establish the oblique rotary tillage torque model.

This paper described the developmental process of rotary cultivator, discussed the technology of rotary cultivation in worldwide, and discusses the rotary tillage effect in the aspect of ecology, economy etc.

Development and experimental research of combined subsoiling and rotary tilling set;

With the basis of theoretical analysing for the possibilities ofdry soil reverse rotary tilling, developed the geometric shape of the reverse rotary tillingblade,the plane-are assembly blades have been designed with CAD technology.

The problems and solutions of mine car scale were summarized,and a novel rotary tilling type mine car cleaner with horizontal shaft was presented in this paper.

On the basis of analyzing the working characteristic and the effect of the rotary cultivation stubble-cleaning implements widely used in China, the problems in the technology of chopping stubble were pointed out.

This paper put forward the teamwork imagine including straw crush, earth up and rotary cultivation, developed out type 1GJQN-165 straw crush-rotary cultivation combination machine, expatiated on this machine s design outline.

In this paper, according to the statistical examination of the experimental data in field and laboratory test, the fundamental statistical properties of working load of engine in plowing and rototilling are summarized.
