RESEARCH OF SOIL TILLAGE BY ADVANCED DESIGN SLIT RIPPER
The essence of work of the soil ripping machine ЩР-4-5 is that the soil is worked with the poles, which are located in the distance of 0,5 meter from each other in alternate order. In this way horizontal ruptures and displacements of soil in vertical and horizontal direction ensures ripping of slotted space.
During the dry years, like during the summers of 2007 and 2008 in the re-gion of Turgaisk, working of fields in the depth of more than 25 centimeters was 102 impossible neither with more commonly used aggregate ПГ-3-5, nor slotted ripper ЩР-4-5.Tractor К-701 could not unitize because it’s wheels stalled on the dry soil when the operative parts were in the depth of more than 25 centimeters because in the whole depth of work the soil was resisting to operative parts (although ЩР-4-5 had 9 operative parts of the factory assembly). This is the reason of waste of fuels and lubricants, early deterioration and breakdown of tractor and operative parts, low productivity of the aggregate, insufficient depth of work, what is influential to development of assemblage of rootlets and, of course, to the crop-producing power, moreover, generation of big clods.Changes made to the construction of the slotted ripper ЩР-4-5 would help to eliminate this bug, reduce the resistance of the soil while it is unitized by the trac-tor, and improve economic factors. Moreover, the productivity of the aggregate and the quality of the work would increase.
Keyword(s): The slotted rip, a-hoe blades, spring-loaded poles, the pulling force of the tractor, the resistance of the soil.
