The bench for simulation research tests of vertical spindle machines for cotton harvesting machines contains spindle drums 1 installed in pairs on holders (not shown) with the formation of a working collar for passing simulators 2 cotton bushes mounted on the element 3 of their longitudinal movement.

Element 3 of longitudinal movement of cotton bushes simulators 2 contains a longitudinal curvilinear guide 4 inside it and has in cross section the profile of a real creek between cotton, while the element 3 of longitudinal movement of simulators 2 cotton bushes is made of separate, interconnected elastic elements 5 sections 6 placed on spring-loaded by means of means for adjusting the compressive force (not indicated) of the springs 7 of the rollers 8.,

The sections b of the element 3 for the longitudinal movement of the simulators 2 cotton bushes are provided with devices for adjusting the compression force (not indicated) of the springs 9 by the rollers 10 for inter 30
