Bucket elevators
Žák, Zdeněk ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
This bachelor thesis deals with the transport equipment using as the main transport element buckets. To specify this is a device type of elevator, conveyor, digger and excavator, including companies producing these devices. Further work is focused on theoretical and technical approach to calculate where the theoretical part of the thesis deals with the mathematical expression shape layers and logarithmic spiral and in the technical part calculations required to design and determine the parameters of devices. The last section is an overview of transported materials.

Driven roller conveyor
Straka, David ; Jonák, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor' s thesis deals with a structural draft of horizontal powered roller track for stock transportation of carton boxes. The trajectory is thought as non storage. The focus of this study is functional computation of the trajectory, determining of main track dimensions, strength computation of operational conveyer parts, draft and examination of track frame. This study includes draft documentation of: track draft, sections of track draft, powered roller and its build, comprehensive tracing of the powered rollers coating and axis.

Centrifugal bucket hoist
Kotačka, Petr ; Malášek, Jiří (referee) ; Jonák, Martin (advisor)
This bachelor thesis deals with bucket elevator design for transport of dry, loose and non abrasive materials according to given parameters. In the introductory chapter a short search describes the concept of suggested solution. Functional calculation, designs and checks of individual proposed equipment elements are stated in the other chapters. In the design requirements for centrifugal bucket discharge as well as miscellaneous way of filling are preferred. Appropriate drawing documentation is enclosed with this thesis.

Worm conveyor
Sedláček, Martin ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
This bachelor thesis deals with calculation and construction of worm conveyor for slightly sloping transport. The whole work is divided into two main sections, which include structural and textual parts. The text contains analysis of option for single parts of conveyor, functional and strength calculations, which are necessary for proposal of worm conveyor. The structural part includes mechanical drawings, which consists of drawing of configuration and drawings of details for worm shaft.

Belt conveyor for recycle aggregate
Benáček, Richard ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
This work deals with an issue of a belt conveyor for transporting recycled stones. The goal of this work is finding a constructional solution of the belt conveyor for specific constructional parameters namely transport power, assigned axial distance of dunes and altitude difference. Firstly, this work includes a theoretical part describing the belt conveyor, the basic constructional element and the choice of the constructional elements. Secondly, this work includes the functional calculation of the belt conveyor according to the ISO ČSN 5048 regulation, the determination of basic sizes, the type of propulsion, the construction of tensioning device and the strength calculation for selected parts. Finally, the drawing documentation find attached to the work.

Magnetic separator
Křupka, Jiří ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
The aim of this bachelor thesis is to design the structural conception of magnetic separator designated to separate small-sized industrial waste. This report provides an overview of facilities of worldwide manufacturers that are used for magnetic separation of steel scrap. Furthermore, it offers an assessment of variants for technical solutions to structural nodes of magnetic separator; this is followed by a selection of specific solution. According to the input parameters, all the parameters necessary for correct machine design are computed. These computations also include the justification of selected table values, placement, surface roughness, geometric tolerances, materials and heat treatment of the individual parts and assemblies. Attachments to this technical report are documentation drawings of selected parts and assemblies.
