Adjustment of quick clamping equipment for application on screener crusher bucket
Hrňa, Lukáš ; Pokorný, Jan (referee) ; Pokorný, Přemysl (advisor)
This thesis deals with the adjustment of quit camping equipment for application on screener crusher bucket Allu SC 3-20 in order to streamline both digging into the bucket, and the actual screening. Using simulation methods in the Adams programme, forces are detected for the digging with the original suspension. Imperfections are revealed for the current full suspension and suggestions made for the new proposedsuspension. The new shape quick release mechanism is designed in CATIA modeler and the I-Deas programme provides final strength control of parts for the proposed mechanism. Finally, both variants are coMPared in terms of digging, sifting the material complexity of the design and the necessary restrictive criteria.

Bucket hoist for food grain transport
Šustek, David ; Pokorný, Prokop (referee) ; Škopán, Miroslav (advisor)
The aim of this thesis is a construction solution of a bucket elevator for transportation of grain with specifiedtransport quantity and specified transport height. In the first part of the thesis, a brief overview of individual parts of the bucket elevator and their influence on the function of the devicewas performed. The conveyor parameters are then determined based on the overview. The second part of this work focuses on the theoretical calculations. Using these calculations, the individual components of the bucket elevator are selected or designed. This part includes a control of the safety of the drive shaft, together with the subsequent calculation of the bearing durability. This thesis further comprisesa relevant drawing documentation of the whole bucket elevator assembly and the subassembly of the driving station.

Centrifugal bucket hoist
Caletka, Tomáš ; Kašpárek, Jaroslav (referee) ; Jonák, Martin (advisor)
This bachelor thesis deals with an engineering design of a centrifugal bucket elevator with transport height 6.5 metres and transport performance 40 000 kilograms per hour. The thesis focuses especially on a functional calculation of the elevator thanks to which a gear motor, band and bucket are chosen. This is followed by an analysis of a constructional solution with a strength check of a drive shaft and parallel keys as well as a calculation of a service life of bearings. Technical documentation according to the task is attached to the thesis.

High loading shovel for loader
Rajdl, Marek ; Papoušek, Libor (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis deals with design of the high loading shovel for the loader Komatsu WA380. The aim is to find constructional solutions of the high loading shovel for a minimal dumping height of 4 500 mm, for the bucket width of 3 000 mm and for the bucket volume of 5 m3. The thesis contains a brief description of the high loading shovel and description of basic constructional components. It also contains choices of basic constructional components, a calculation of the necessary force to tilt the bucket and a static analysis. Stress control of the bucket, the frame and the pegs forms the final part of the thesis. The thesis is accompanied by the necessary technical drawings.

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.

Tilting head for mini excavators
Zámečník, Stanislav ; Sojka, Michal (referee) ; Škopán, Miroslav (advisor)
The diploma thesis deals with the structural design of the tilting hitch intended for mini-excavators. This thesis includes a critical research of similar devices. Based on this research, there is a custom design of tilting hitch with tilting using linear hydraulic motors created. Furthermore, all necessary calculations of the main parts and strength analysis of the supporting structure are carried out and drawing documentation is created. This diploma thesis was developed in cooperation with the company STAVES s.r.o..

Bucket elevator for transporting glass shards
Kopecký, Michal ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor's thesis deals with the functional design of a bucket elevator for transporting glass shards with a lifting height of 10 meters and a nominal transport capacity of 60 tons per hour. The research part provides a brief introduction to the issues of bucket elevators and the current market for such elevators. In the subsequent sections, functional calculations are performed, and the selection of individual components is made. Lastly, the strength calculation of the drive shaft and sealing rings, as well as the bearing life assessment, are conducted. The thesis includes accompanying drawing documentation.
