Design of single-purpose cutting machine for shortening of plant stems
 Žižka, Jakub ; Brandejs, Jan (referee) ; Vespalec, Arnošt (advisor)
This bachelor thesis deals with the design of a single-purpose machine for cutting plant stems. The task of the machine is to cut already partially shortened and stripped wheat straw stalks to the required length. The operation of the machine is fully automated, the operator only ensures the supply of semi-finished products to the machine, removes the finished stalks and controls the operation of the machine. In the thesis is a search describing the existing technologies used for cutting plant stalks, the possibility of driving a single-purpose machine and possible solutions for transporting stalks. The research also includes an analysis of the necessary mechanical and physical properties of wheat stalks. Subsequently, the analysis of information from the research part of the thesis and the definition of important parameters for the design construction balance sheet is performed. In the practical part of the work are developed concepts of possible solutions of individual structural nodes and justification of the choice of individual solutions. The second part of the practical part deals with the construction design of a selected conceptual design, including calculations. The work shows a possible solution for the construction of a machine for processing semi-finished products with a large variety of shapes.
