Hodnocení sklízecích mlátiček CLAAS LEXION 780 při sklizni obilovin a řepky ozimé v podniku zemědělské prvovýroby
ROUČKA, František
This Bachelor thesis, with main topic of global reviewing exact harvesters Class Lexion 780 during harvesting cereals and winter rape in primary agricultural company, deals with actual and present summary about harvesting a separating apparatus used in those harvesters. It also mentions individually designed units used inside of harvester Claas Lexion 780. Theoretical part of this thesis ends with chapter focusing on mowing adapters for harvesting cereals and it is complemented with simple description of belt using harvesting adapter produced by MacDon company. Practical part of this thesis deals with methodics and measuring results related to harvesting quality in terms of losses, grinding quality and spreading afterharvesting leftovers, efficiency a consumption. Thesis is also complemented with agricultural operation characteristics and simple investment and running analysis.

Vliv sklízecích ústrojí sklízecí mlátičky na ekonomiku jejího provozu
Duba, Tomáš
This bachelor thesis deals with issue of combine harvesters adapters for agricultural crops harvesting. In the main part are separated and described each single methods of harvesting, harvesting adapters and their functional groups, by which is the harvesting of various crops done. Then, technical solutions of harvesting equipment producers are described there. In the next part are listed electronical systems, which are being used in automatical guidance of harvesters in growth for their maximal use.

Přiháněč sklízecích mlátiček
Janča, Dominik
Bachelor thesis "The reel forage harvester" is aimed at describing the track reel, their function and correct setting, which is important to reduce losses at harvest. There are divided combine harvesters by construction execution of the main gear and equipment. It also deals with the distribution of harvesting adapters for various crops. To conclude, the work deals with the comparison reel adjustments during the harvest different crops and its orbit at work.

Možnosti využití automatizačních prvků sklízecích mlátiček
Skula, Miroslav
Thesis on topic of the possibilities of automation components for combine harvesters. It deals with the issue of direct production of cereals using combine harvesters, fitted with automation components. The first part of the thesis contains a definition of the combine harvester with all the agrotechnical requirements. The combine harvesters are further distributed by some specific criteria like the threshing and the separation system. Further on are mentioned and described the combine harvesters automation systems supplied to the world market. In the practical part of the thesis is a detail explanation of the method used for the performed laboratory field measurement, the process and the followed processing and evaluation of the results. One selected combine harvester was used for observation and testing of the grain losses depending on the forward ground speed and a different setting of the working mechanisms using some automation components from the onboard cockpit computer of the combine harvester. In the conclusion of the thesis all the results were mentioned and the effect of combine harvester setting on the grain losses was evaluated.

Bubnové mlátiace ústrojenstvo obilných kambajnov a jeho modifikácie
Petrek, Dávid
Bachelor thesis is devoted to the description of harvesters, which is the most important link threshing devices. Is this classification harvester workflows harvesting seed crops. I gave a comprehensive overview of tangential harvesters from leading manufacturers. The paper also describes the structure and function of individual harvesters. The determining factor for quality and quantity, collection will be technology of collection. Standards witch are put on this technology are too high therefore pay attention for perpetuance innovation of technology and suitable setting are very important.

Threshing system of combines harvester
Štelcl, Michael ; Červinka, Jan (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis is about evaluation of maximum throughput of straw and grain together, in various types of threshing units which are used in combine harvesters. It provides basic informations about two types of combine field-test procedures. In the end of work is shortly describe current development of combine harvesters and contain two proposals of alternative constructions of threshing units according to author of this bachelor thesis.

Model ranges analysis of threshing machine
Palík, Milan ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The scope of this bachelor work is to give the basic information and explain the functionality of particular harvester thresher mechanism and confront their synthesis and product mix from different producers. The agricultural engineering sale is large and that is why the first step of the usage will be the company literature and then professional magazines will be given. This work is mainly made through the use of visual documentation, which afford explanation of existing mechanics principle, their particular structural design and summary of producers. Then there will be mentioned their percent sales representation and the confrontation according to the efficiency classes. The attention will be first of all paid to the best in this field, for example to the companies, which are engaged in picking engineering production for cereals, as are for example companies Claas, Fendt. Case IH or New Holland.

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.

Rating combine harvesters NEW HOLLAND CR 9080 and NEW HOLLAND CX 8090 at the harvest of cereals and oilseed rape in service company.
ŽELEZNÝ, Josef
The dissertation Comparison combines with a different implementation of threshing unit at harvest of cereals and oilseed rape in the theoretical part provides an overview of the design and development of the main parts of the combine, especially focusing on the threshing unit together with the development of other units providing greater efficiency and performance. The practical part presents the methodology and results of field-laboratory measurements to compare activity combines New Holland CX 8090 and New Holland CR 9080 in terms of loss of quality crushing and spreading crop residues, fuel consumption and performance.
