METHOD OF GENERAL-TILLAGE CULTIVATOR PRODUCTION Russian patent published in 2009 - IPC A01B35/00 

FIELD: agriculture.

SUBSTANCE: at first, an operating width for average thrust power of tractor is selected. Thereafter, a bar frame is selected and operating elements are disposed. At first, minimal required operating width of general-tillage cultivator is calculated according to the ratio Bmin.= (Tmin. Cr)/ Rc. (n+1), where Tmin. - minimal current capacity of tractor, Cr. - capacity ratio of tractor 0.8-0.9, n - number of operating elements in a row, starting with 1, k - number of rows, Rc - resistivity constant of operating element. Thereafter, a type of operating elements, pattern array are selected, whereat working length of the bar frame Br. is fixed, note that it should corresponds the inequation Wl.<Br.>Wl., where Wl. - width of attachment sector of hitch lock CA-1. Thereafter, to apply another tractor I<Mn.tr./(Tmin.Cr.) is determined. I - integer, if it is even - hitch lock CA-1 is left in the previous place, and if it is uneven, hitch lock CA-1 is replaced on the joint of two Bmin. The hitch lock is designed with the possibility of being moved along the frame, the length of which on using a tractor Br.n. is Br.n.=Bmin. (1+I), hereafter the operating width is increased to 7-8 m. Thereafter, self-castering wheels are fixed on the ends of the frame, and after open-side joints with hydraulic cylinders are fixed with the possibility of folding side wings in the transport position upward or on the level forward. The operating width of cultivator is increased by the value Bmin. symmetrically from the both ends after the joints till the power of tractor is exhausted.

EFFECT: development of the method for general-tillage cultivator design envisaging more quantity of tractors with low power.
