Wood chipper - efficiency
Šulák, Petr ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
The objective of this bachelor thesis is to design the wood chipper. In the theoretical part I am dealing with the mechanical properties of the processed material. Furthermore, I am mentioning individual types of chippers and crushers. In the practical part, the basic parameters of the machine are deduced from the research. These values are entering into the calculations needed to construct the components that the chipper is assembled with. The thesis includes production drawings and a 3D model made in Autodesk Inventor 2019.

Production of crusher on the plastic waste
Květoun, Jan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
This thesis is focused on designing and manufacturing a shredder for plastic waste 2H for small companies, households and blocks of flats. Thesis contains brief description of plastics, their properties and usage in praxis. It deals with excessive production of plastic, noncircular economy of waste and unsatisfactory processing of plastic waste. There are examples of collecting, sorting and recycling technologies and their application in praxis. It consists of current overview of shredders available on Czech and Slovak market and their comparison. Practical part of this thesis focuses on design itself, its components, parameters and economic issues of manufacturing. Annex contains 3D model of shredder assembly, bought components overview, assembly drawings and photo documentation of created shredder.

Mechanical design of plastic parts crusher
Šebesta, Karel ; Brandejs, Jan (referee) ; Paloušek, David (advisor)
The thesis focuses on the construction of shredder of plastic components produced by 3D printers. The aim of the thesis is to design a shredder whose output components, the so-called flakes, could be used to produce recycled filament. The first part of the thesis covers an analysis of technology of shredding. Furthermore, the properties of shredded material and the requirements for the quality of output granules are determined. Based on the research, the parameters for the efficient shredder are defined. In accordance with these parameters, several variants are created, from which the final design of the two-stage shredder is selected and constructed.

Porovnání hloubkového kypření a zpracování půdy orbou
PROCHÁZKA, Miroslav
The final thesis is theoretical-research. It is divided into theoretical and practical parts. The theoretical part deals with the soil from the point of view of its importance for man and introduces its types. From the point of view of soil cultivation it introduces two different technologies of its processing, namely plowing and deep loosening. It shows types of cultivators and plows. The research part analyzes the results of the research obtained by practical measurement of yields in the spring barley sowing using both tillage technologies. It compares these technologies in terms of economy, impact on growth, soil and yield.
