In consideration of the needs of human beings, machinery and computation, the model has been used for structural design combined with relevant knowledge, means, maneuver and strategy.
More than one hundred modern farm tractors from nine countries were shown at Peking Foreign Agricultural Machinery Exhibition in 1978. This paper, on the basis of synthetic analyses of the technical specification, structural characteristics, productive capacity, operation performance and adaptability etc for various kinds of tractors, will probe into the development trends of tractor and its assembly-parts structure.
The boat-type tillage machine is a newly developed power machinery in irrigated land,intia-tively created by China.This paper,through practice of boat-type tillage machine,and analysis of experimental dataas well as deductions of formula,makes a primary trial to develop from a stage of generalperformance analysis to a stage of determining reasonable structure parameters.Through the principal operation of the boat-type tillage machine such as plowing,the totalforces system in the longiludinal plane hav...
This paper is the continuation of Design about Sliding Way Mechanism of SteeringArm for Power Rice Transplanter(Ⅰ) (A. A. S. Vol. X No. I). The power rice transplanter including 9 models was authenticated and finalized from August to November in 1979. The whole series unitedly adopts the inner-cam controlling me-chanism of planting crank for the rotoring-vertical path.According to choice the technical parameters of the sliding way mechanism of steering arm and the results of experiment, the paper makes a sy...
