Bucket elevator
Sklenář, Adam ; Kašpárek, Jaroslav (referee) ; Jonák, Martin (advisor)
This bachelor thesis deals with the design of a vertical bucket elevator for transport of grain. The thesis consists of a description of bucket elevators and their main components, functional calculations and check of the drive shaft. Particular emphasis is placed on the calculation and selection of a gearmotor and subsequent strength check of the drive shaft. The drawing documentation of the entire assembly of the elevator, the elevator head assembly and drive shaft is enclosed with the thesis.

Conceptual description of the design of bucket elevator
Růčka, Martin ; Škopán, Miroslav (referee) ; Jonák, Martin (advisor)
The topic of this bachelor work is to describe the design process bucket elevator. Work is processed as study material for students of bachelor study. The first part is a basic description of the bucket elevator and its types. Furthermore, the description of the basic parts of the bucket elevator. The second part contains equations for bucket elevator design (design drawing element, buckets, engine). Are given two ways to resolve according to [1, 2] and the conclusion of this work is presented a comparative calculation of these solutions.

Design Optimization of Bucket Conveyors
Jonák, Martin ; Svěrák, Tomáš (referee) ; Zegzulka, Jiří (referee) ; Malášek, Jiří (advisor)
This thesis deals with a study of methods sufficient to describe the behavior of bulk materials (homogeneous and non-homogeneous) during their transport by bucket elevators in the application focused on the optimization of the bucket shape and also on the optimization of operating parameters of whole elevator. More specifically, this thesis is based on the studying and creating analytical and numerical computational models which are used for description of flows and deformations especially of particulate materials. Firstly, the thesis is focused on the process of discharging the bucket – the relationship among the shape of the surface of a particulate material and geometry, position and movement of the bucket. The beginning and way of discharge of the bucket will be determined. Secondly, the thesis includes the overall computational model of a bucket elevator which is based on discrete element method and presented in the case study. The goal is to determine the limits of some classical physical and mathematical descriptions.

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.

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.
