Samojízdné stroje a sklízeče v rostlinné výrobě
Karásek, Tomáš
This thesis gives an overview about self-moving machines and harvesting machines currently used in vegetable production. It mainly focuses on self-moving machines for harvesting of cereals and fodder crops. It focuses only marginally on machines for chemical protection and crops' fertilisation and machines for harvesting of root crops and special crops. History, development and individual functional parts are described at chosen self-moving machines. It deals in detail with possibilities of using of different types of adapters for self-moving threshing machine and self-moving cutting machine. Self-moving threshing machines were chosen for technical and technical-economic evaluation.

Návrh technického zajištění terénních úprav a revitalizace ve vybraném území
Baloušová, Věra
Thesis deals with restoration measures at two selected locations. They were processed technological procedures recommended by the equipment used for laying down the operating costs. These figures were calculated minimum and maximum costs for implementing each variants. Compared with similar calculations showed that the results are real and can have practical use.

Stroje pro šlechtitelské a semenářské provozy
Skřivánková, Eva
This work deals with the characteristics of breeding and seed operations, with a focus on their technical equipment. Furthermore, there are described operations from soil preparation, through the pre-sowing preparation, sowing to harvesting and subsequent processing and treatment of seeds. The largest part of this work is an overview of the different machines used on small parcels of land. Included are photos of selected machinery.

Návrh údržby a technického zajištění vybraného modelového území (sídlištní zeleň)
Březina, Petr
This thesis addresses the issues associated with the maintenance of green spaces and assembly processes. It describes the different categories of automated equipment such as lawn tractors, scarifiers, brush cutters and various hand tools. For these compositions are described in part processed drawing tables, which contain their technical parameters. Another part is to select a model green building settlement drawn technological maintenance procedure with the addition of suitable machinery. It is also estimated economic cost to perform the operations. Dissertation with complementary image attachments described mechanization.

Využití cyklických korozních testů pro antikorozní systémy určené do prostředí průmyslových hnojiv
Konečný, Martin
The diploma thesis is focused on use of cyclic corrosion tests for anti-corrosion systems meant for an environment of industrial fertilizers. The theoretical part is occupied with a description of industrial fertilizers in agriculture, machines for their application and manipulation. Next part of theory is dealt with corrosion factors, corrosive environments including an aggressive environment with acidic and alkaline pH, and last but not least a protection from corrosion. In the practical part there are chosen anti-corrosion systems based on technical data sheets, that are tested on prepared samples by corrosion degradation and by mechanical tests such as cylindrical bend test, pull off test and Erichsen cupping test. Next there is measured corrosion weight loss of non-alloy carbon steel plate. The final part is about data analysis from previously mentioned tests and there is included a suggestion of suitable anti-corrosion protection into a highly aggressive environment.
