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.

Stanovení potenciálního množství biomasy pro energetické využití u LDO Přibyslav
Benc, Martin
Aim of this diploma work was assessment of biomass potential quantity for energetic using at LDO Přibyslav,especially at forest administration of Staré Ransko. Total quantity of biomass, which can be obtained from mature stand for energetic using was determined at study area. Further issues of appropriate technology of collecting and transporting of logging residues and possibilities of wood chips processing are dealt. There was found in total 49 019.07 tons of available quantity of biomass at the mature stand at research area. Technology of logging residues transporting to a roadside landing and its chipping was designed on the base of findings.

The trailer for a chipper
Poul, Ondřej ; Robotka, Tomáš (referee) ; Kašpárek, Jaroslav (advisor)
The goal of this thesis is structural design of the trailer for a LASKI chippers and to create a construction drawings. Important part is information about legislation rules, which this trailer has to fulfill. The aim of this work is to do a dynamic simulation using multi-body system. Results of this simulation are used for a stress analysis witch using a fine element method.

Design of mobile chipper
Svoboda, Tomáš ; Šuranský, Michal (referee) ; Brandejs, Jan (advisor)
The Bachelor thesis deals with the structural design of a mobile chipper that uses mass-produced compact tractors VARI as its energy sources. This Bachelor thesis is divided into four main chapters: a description of the basic technology used for processing natural materials that is characteristic of this type of equipment, the current state of structural details of compact tractors VARI and their equipment, a detailed study of technical aspects of the compact tractor providing the power, various drafts of possible solutions with a presentation of a functional home-made prototype, and a detailed description of the final version of the design. The thesis also includes an approximate calculation of the maximal possible diameter of the processed material and a technical drawing.

Rozbor možností zpracování a využití dendromasy získané při arboristických činnostech
Matěna, Jiří
These Bachelor's Theses are oriented on processing and utilization of dendromass that is produced as a result of some arboristic activities. Totally 50 arboristic companies and arborists were evaluated. The single subjects are evaluated especially from the point of view of firewood and wood chips production. The main purpose was to check which activities result in production of dendromass and what are the possibilities of its final treatment and utilization. As for dendromass processing these theses are concentrated on daily production, type of necessary machinery, labour consumption and financial profitability. During the last years there have occurred new possibilities of dendromass processing and using small and large machinery.
