RESEARCHES REGARDING THE MECHANO-PNEUMATIC DISTRIBUTION ON THE STRAW CEREALS SOWING MACHINES

This paper presents some theoretical considerations regarding the calculus, design and running of the mechano-pneumatic distribution devices which equip the straw cereals sowing machines. The distribution devices make the seeds measuring and their bleeding to the driven pipes for shovels. This measuring and bleeding process, named the seeds distribution process, affects over the main qualitative index of the sowing machine: flow rate stability, sowing norm, distribution uniformity on the working width, distribution uniformity on row. In paper there are accentuated the advantages of using these distribution devices types in contrast with the classical distribution devices.
