Research of stress-strain state of tank of small-size self-propelled sprayer

Scientific journal of the Ternopil national technical university
For the developed design of a small-sized self-propelled sprayer, it is proposed to use a tank from which the working fluid is displaced under pressure in the power system of the spraying devices. For the safe operation of such a shell, a method of determining its stress-strain state has been developed.

Automatic Control of Boom Height and Positioning on a Self Propelled Sprayer

World Congress of Computers in Agriculture and Natural Resources, Proceedings of the 2002 Conference, 2013
Owing to the control of erosion caused by rainwater, the lands have contour curvesthat make difficult the sprayer movement and stability. The sprayer's operator,besides driving, aligning in the paths between the plants rows, also looks forcontrolling the height of the boom sections in order to keep them from touching theground and at an appropriated ...
