Description

Przedmiotem wynalazku jest zgarniak do czyszczenia prowadnic rynien zgrzeblowych prze¬ nosników górniczych zaopatrzonych w ogniowe ciegna lancuchowe usytuowanych we wnekach prowadnic.W czasie transportu urobku z miejsca wydobycia przenosnikami zgrzeblowymi zdarzaja sie czesto przypadki zanieczyszczenia wnek prowadnic mialem weglowym, kamiennym lub lupkami w postaci zwartej masy w wyniku obfitego zraszania urobku woda przez kombajny wzglednie tez eksploatacji pokladów zawodnionych. W wyniku zanieczyszczenia prowadnic nastepuje znaczny wzrost oporu przesuwanego ciegna powodujac znacznie zwiekszony pobór mocya takze doprowa¬ dzajacy czesto do zaklinowania lancucha a w konsekwencji do jego zerwania.W celu niedopuszczenia do zanieczyszczenia prowadnic, kopalnie stosuja zuzyte noze kombaj¬ nowe, wzglednie plaskowniki czesto zbrojone weglikami spiekanymi i zamocowane przy pomocy sruby do ogniwa lancucha usytuowanego w pozycji poziomej. Stosowane sa nieraz kawalki preta przyspawanego do zamka bocznego ciegna lancuchowego. Wada tak uzbrojonych ciegien lancu¬ chowych jest niedokladne czyszczenie prowadnic rynien, ponadto ostre konce narzedzi powoduja niszczenie wnek prowadnic.Celem wynalazku jest opracowanie zgarniaka umozliwiajacego dokladne czyszczenie wnek przenosnika zgrzeblowego.Wedlug wynalazku zgarniak stanowi jednolity element wykonany jako odkuwka w postaci ksztaltki skladajacej sie z korpusu i glówki. Zgarniak zamocowany jest do ogniwa poziomego przy pomocy sruby z lbem klinowym. Dla wlasciwego prowadzenia lancuchów w rynnach, zgarniaki sa mocowane symetrycznie po obydwu stronach ciegna i w odstepach przecietnie co dziesiec odcin¬ ków trasy. Zaleta skonstruowanego zgarniaka jest zapewnienie bezawaryjnej pracy przenosnika wskutek zanieczyszczenia, zmniejszenie poboru mocy i wytapiania sie bezpieczników topikowych.Wynalazek blizej przedstawiony jest w przykladzie wykonania na rysunku, na którym fig. 1 przedstawia widok zgarniaka z przodu w ukladzie z ogniwem i prowadnica rynny, fig. 2 — widok z góry.2 120327 Zgarniak stanowi jednolita ksztaltka skladajaca sie z korpusu 1 i glówki 2. Korpus 1 posiada dwa pólokragle rowki 3 o rozstawie odpowiadajacym szerokosci ogniwa lancucha 6. Prostopadle do rowków 3 korpus 1 posiada otwór 4 do osadzenia sruby 7 z lbem klinowym 8 osadzonym po zamontowaniu pomiedzy ramionami ogniwa 6. Sruba 7 zabezpieczona jest przed odkreceniem nakretka 9.

Naklad 120 egz.Cena 100 zl PLThe subject of the invention is a scraper for cleaning the guides of the card gutters of mining conveyors equipped with fire chain links located in the recesses of the guides. During the transport of the spoil from the place of extraction by card conveyors, there are often cases of contamination of the guide slots with coal dust, stone or slate in the form of a as a result of abundant sprinkling of the excavated material with water by combine harvesters, or the exploitation of wet decks. As a result of contamination of the guides, the resistance of the moving tendon increases significantly, causing a significantly increased power consumption, also leading to the chain jamming and, consequently, its breaking. In order to prevent contamination of the guides, mines use worn-out combine knives, or flat bars often reinforced with carbide and fastened with a bolt to a chain link arranged in a horizontal position. Sometimes pieces of rod welded to the side lock of the chain string are used. The disadvantage of such armed chain cords is inaccurate cleaning of the gutter guides, moreover, the sharp ends of the tools cause damage to the guide grooves. The aim of the invention is to develop a scraper that allows for thorough cleaning of the scraper conveyor cavities. and heads. The scraper is attached to the horizontal link with a wedge-headed bolt. For proper guidance of the chains in the gutters, the scrapers are mounted symmetrically on both sides of the string and at intervals of approximately every ten route sections. The advantage of the constructed scraper is to ensure failure-free operation of the conveyor due to contamination, reduction of power consumption and melting of fuse fuses. The invention is presented in more detail in the example of the embodiment in the drawing, in which Fig. 1 shows a front view of the scraper in a system with a link and the gutter guide, Fig. 2 - top view.2 120327 The scraper is a uniform shape consisting of the body 1 and the head 2. The body 1 has two semi-circular grooves 3 with a spacing corresponding to the width of the chain link 6. Perpendicular to the grooves 3 the body 1 has a hole 4 for mounting the screw 7 with with a wedge head 8 mounted between the arms of the link 6. The screw 7 is secured against unscrewing the nut 9. The head 2 has a shape on the side of the rake face 5 corresponding to the profile of the recess 11 of the gutter guide 10. Patent claims 1.
