Drėgnų kukurūzų burbuolių kūlimo ir grūdų separacijos pro pobūgnį tyrimai / Wet corn cobs threshing and grain separation

Jackis, Donatas 18 June 2010 (has links)
Magistratūros studijų baigiamojo darbo apimtis 66 puslapiai, kuriuose yra 64 paveikslai ir 4 lentelės. Literatūros sąraše 50 šaltinių. Darbo pradžia 2008 09 01, pabaiga 2010 05 10. Objektas. Keturi skirtingi pobūgniai, kurie skyrėsi savo konstrukcija ir aktyviu separacijos plotu. Tikslas. Nustatyti drėgnų (> 35%) kukurūzų burbuolių iškūlimą, grūdų separaciją pro tiriamus pobūgnius ir grūdų sužalojimą sąlygojančius veiksnius bei pagrįsti racionalias jų vertes. Aktualumas. Pateikto darbo literatūros apžvalgoje išanalizuota kukurūzų grūdų nuėmimo technologijos ir kukurūzų burbuolių kuliamųjų konstrukciniai ypatumai. Atlikta mokslinių tyrimų apžvalga, kurioje išsamiai išanalizuoti kūlimo aparatų technologinių reguliavimų ypatumai, kuliant drėgnas kukurūzų burbuoles ir apibendrinti grūdų separaciją pro pobūgnį sąlygojantys veiksniai. Lietuvoje labai drėgnų (> 35%) kukurūzų burbuolių kūlimas mažai tyrinėtas, todėl būtina išanalizuoti kaip keičiasi iškultų grūdų separacija pro pobūgnį, naudojat skirtingų separacijos plotų pobūgnius. Rezultatai. Eksperimentiniais kukurūzų burbuolių kūlimo tyrimais nustatyti tangentinio kūlimo aparato racionalūs technologiniai parametrai kuliant labai drėgnas kukurūzų burbuoles. Tyrimais pagrįsta, kad pobūgnio aktyvus separacijos plotas ženkliai įtakoja grūdų separaciją. Nustatyta tiekiamų burbuolių srauto įtaka iškultų grūdų separacijai pro atskiras pobūgnio dalis. Taip pat nustatytas kūlimo procesui reikalingos galios poreikis, kuris kinta nuo 1,5... [toliau žr. visą tekstą] / The Master thesis consists of 66 pages, including 64 figures and 4 tables. There are 50 sources in the references. This work was started on the 1st of September 2008 and finished on the 10th of May 2010. The object of the work. Four concaves where the difference between them was their construction and active separation area. The aim of the research. The aim of the research is to define wet (> 35) corn cobs’ threshing, grain separation, factors that determine harm and, also, to motivate their rational values. Relevancy of the research. Certain maize grain harvesting technologies and structural peculiarities of corn cobs threshing-machines’ are analyzed in the literature review. The peculiarities of threshing-machines’ setting while threshing wet corn cobs are analyzed as well. Furthermore, special factors that necessitate grain separation through the concave are also generalized in this thesis. However, extremely wet (> 35) corn cobs’ threshing is only slightly studied in Lithuania. It is essentially important to analyze the shift of the threshing grain separation through the concave, using concaves that have different separation areas. The results. Rational technological parameters of tangential threshing-machine are defined by experimental researches of corn cobs’ threshing. This was done by threshing extremely wet corn cobs. The influence of supplying corn cobs flow to the separation of threshing corns through the particular parts of concave is identified. Finally... [to full text]

Performance of a tangential feed threshing cylinder as affected by corn cob break-up and concave design parameters.

Wall, Gavin Lindsay. January 1981 (has links)
A laboratory threshing unit was constructed utilising a standard tangential feed ("conventional") combine cylinder, concave, beater and transition grate. This unit was used to study the phenomenon of corn cob break-up and its effect on the performance of the threshing unit. It was found that the degree of corn cob break-up was affected by cylinder peripheral speed, cylinder-concave clearance and hybrid cultivar. Within the hybrid cultivars used, increased cob break-up was associated with decreased shelling efficiency and concave separation efficiency. / The possibility of reducing kernel damage and increasing concave separation efficiency by changing some of the concave design parameters was investigated. A mathematical model of the tangential feed threshing unit was developed and used to investigate the effect of the concave design parameters. Experimental data indicated that kernel damage may be reduced by at least 24 per cent and concave separation efficiency increased by at least 38 per cent.
