Description

Przedmiotem wynalazku jest ciagnik kombajnu weglo¬ wego z napedowym kolem o osi obrotowej prostopadlej do spagu, posiadajacy osloniety lancuch pociagowy.The subject of the invention is a coal-loader tractor with a drive wheel with an axis of rotation perpendicular to the spag, and having a sheathed pull chain.

Znana dotychczas konstrukcja kombajnów weglo¬ wych z ciagnikami lancuchowymi wyposazonymi w kola napedowe o osi prostopadlej do spagu, posiadaja rolki lancuchowe osadzone w tej samej plaszczyznie w kadlu¬ bie ciagnika. W tych kombajnach lancuch pociagowyjest wyprowadzony z ciagnika do przestrzeni oslonietej w zastawkach przenosnika, za pomoca dodatkowego zestawu dwóch rolek lancuchowych, przymocowany do przedniej i tylnej czesci san kombajnu. Dodatkowe zestawy rolek lancuchowych, wyprowadzajace lancuch pociagowy do przestrzeni oslonietej, sa zródlem licznych usterek mechanizmów spowodowanych trudnymi wa¬ runkami pracy w przestrzeni silnie zanieczyszczonej urobkiem, oraz sa przyczyna powstawania znacznych strata tarcia przy wspólpracy tych rolek z lancuchem pociagowym.The hitherto known construction of coal harvesters with chain tractors equipped with drive wheels with an axis perpendicular to the spag, have chain rollers embedded in the same plane in the tractor hull. In these combines, the pull chain is led out of the tractor to the space protected in the conveyor valves, by means of an additional set of two chain rollers, attached to the front and rear parts of the combine's san. Additional sets of chain rollers leading the pull chain into the shielded space are the source of numerous mechanism failures caused by difficult working conditions in a highly contaminated space, and are the cause of significant friction losses when these rollers cooperate with the pull chain.

Ciagnik z oslonietym lancuchem pociagowym wedlug wynalazku, wyposazony jest w ciagnik lancuchowy z kolem napedowym o osi obrotu prostopadlej do spagu.The tractor with a shielded pull chain according to the invention is equipped with a chain tractor with a drive wheel with the axis of rotation perpendicular to the spag.

Lancuch pociagowy wyprowadzony jest z kola napedo¬ wego do przestrzeni oslonietej w zastawkach przenosnika za pomoca dwóch rolek lancuchowych, umieszczonych na dwóch prostopadlych do siebie plaszczyznach i pro¬ wadnika lancucha umieszczonego przy plozie kombajnu.The pull chain is led out of the pulley to the space protected in the conveyor valves by means of two chain rollers placed on two planes perpendicular to each other and a chain guide placed at the shearer's skid.

Zastosowanie w ciagniku, przy napedowym kole lancu¬ chowym, rolek lancuchowych o osi obrotu równoleglej do spagu i osi wzdluznej kombajnu pozwala wyelimino¬ wac dwie rolki lancuchowe z ukladu pociagowego. Osa¬ dzenie rolek wspólpracujacych bezposrednio z napedo¬ wym kolem w saniach kombajnu pod kadlubem ciagnika, ulatwia równiez w sposób istotny ich wymiane w razie uszkodzenia.The use of chain rollers with the axis of rotation parallel to the spag and the longitudinal axis of the combine in the tractor, with the drive chain wheel, allows to eliminate two chain rollers from the train system. Placing the rollers working directly with the drive wheel in the shearer sled under the tractor hull also significantly facilitates their replacement in case of damage.

Wyprowadzanie z ciagnika lancucha pociagowego do przestrzeni oslonietej w zastawkach przenosnika za pomoca prostego w konstrukcji elementu w postaci pro¬ wadnika slizgowego, zapewnia niezawodna prace ukladu pociagowego w trudnych warunkach eksploatacyjnych.Leading the pull chain from the tractor to the protected space in the conveyor valves by means of a simple element in the form of a sliding guide, ensures reliable operation of the train system in difficult operating conditions.

Zaletami ciagnika kombajnu z oslonietym lancuchem pociagowym, jest prosta konstrukcja ukladu pociago¬ wego, minimalne straty tarcia oraz duza trwalosc i nieza¬ wodnosc mechanizmów.The advantages of a combine tractor with a shielded pull chain are the simple structure of the train system, minimal friction losses as well as high durability and reliability of the mechanisms.

Przedmiot wynalazku pokazano w przykladzie na rysunku, na którym fig. 1 przedstawia widok z przodu mechanizmu, fig. 2 przekrój poprzeczny ciagnika i san kombajnu i fig. 3 — przekrój przez zastawkeprzenosnika z prowadnikiem lancucha umocowanym do plozy kombajnu.The subject of the invention is shown in the drawing, in which fig. 1 shows a front view of the mechanism, fig. 2 - a cross-section of the tractor and the combine harvester, and fig.

Ciagnik lancuchowy z oslonietym lancuchem pociago¬ wym, zwlaszcza do kombajnów weglowych, wyposazony jest w napedowe kolo lancuchowe 2, które wspólpracuje bezposrednio z dwoma rolkami lancuchowymi 3o osiach obrotowych 4 prostopadlych do osi obrotowej 5 kola lancuchowego 2, obudowy 6 rolek lancuchowych 3, przy-112 288 mocowane sa do san 7 kombajnu 1. Lancuch pociagowy 8 wyprowadzony jest z rolek lancuchowych 3 do prze¬ strzeni oslonietej blachami zastawki 9, przenosnika 10 i pokrywami obrotowymi 11, za pomoca rolek lancucho¬ wych 12 i prowadników lancuchowych 13 umieszczonych przy plozach 14 kombajnu 1. Obudowy 15, rolek lancu¬ chowych 12 oraz prowadniki lancuchowe 13 przymoco¬ wane sa do san 7 kombajnu 1. Odmiana rozwiazania wedlug wynalazku jest umocowanie prowadników lancu¬ chowych 16 do plóz 14 kombajnu 1. Pokrywy obrotowe 11 zamykane pod wplywem dzialania napiecia nastep¬ nego sprezyny, otwierane sa powierzchniami oporowymi prowadników lancucha 13 i plóz 14 kombajnu 1.A chain tractor with a shielded pull chain, especially for coal harvesters, is equipped with a drive chain wheel 2, which works directly with two chain rollers 3 with rotational axes 4 perpendicular to the rotational axis 5 chain wheel 2, casing 6 with chain rollers 112 288 are attached to the sled 7 of the combine 1. Pull chain 8 is led out from chain rollers 3 to the space covered with gate plates 9, conveyor 10 and rotary covers 11, by means of chain rollers 12 and chain guides 13 located at the skids 14 in the combine 1. Housings 15, chain rollers 12 and chain guides 13 are attached to the sled 7 of the combine 1. A variant according to the invention is the attachment of lance guides 16 to the slides 14 of the combine 1. Revolving covers 11 closed under the effect of tension the next spring, they are opened with the supporting surfaces of the chain guides 13 and slides 14 of the combine 1.
