****lt t«5**l Int. Cl.4 E21C 25/10 Twórcy wynalazkut Jan Myrczek, Norbert Pioseczny, Rajmund Josko9 Michal Fele, Kazimierz Franozak, Stanislaw Orchel, Marek Baryoki Uprawniony z patentu: Rybnicko-Jastrzebskie Gwarectwo Weglowe Kopalnia Wegla Kamiennego "Borynia", Jastrzebie Zdrój (Poleka) ORGAN URABIAJACY KOMBAJNU SCIANOWEGO Przedmiotem wynalazku jest organ urabiajacy kombajnu soianowego utworzony z piasty w fonnie walca, zaopatrzony w czolowa tarcze, a wzdluz piasty zaopatrzony w srubowo zwiniete ladujace platy, który ma do ozolowej tarozy i krawedzi platów zamocowane urabiajaoe noze.Organ Jest przeznaozony do urabiania zwiezlego wegla oraz skal plonnyoh wystepujacych w po¬ kladzie. Znany z opisu patentowego RFN nr 3 105 732 urabiajaoy organ ma oylindiyozna piaste z czolowa tarcza, a na piasoie ma ladujace platy zwiniete w linie srubowa. Platy te sa dwo¬ jakiego rodzaju, a to jedne rozoiagaja sie na oalej dlugosci piasty i sa zaopatrzone w skra¬ waJaoe noze na zewnetrznej krawedzi. Drugi rodzaj platów, rozmieszczonych w polowie odleglo¬ sci miedzy platami pierwszego rodzaju, siegaja od krawedzi piasty do polowy jej szerokosoi i sa usytuowane w organie po przeciwnej stronie piasty w stosunku do ozolowej tarczy. Ich zew¬ netrzna krawedz sklada sie z czesoi wznoszacej od powierzchni piasty do wysokosoi pozosta¬ lyoh platów, a w sasiedztwie krawedzi piasty platy te maja stala wysokosó. Organ ten zostal zaopatrzony w dodatkowe, krótkie platy w celu uzyskania bardziej równomiernego splywu urobku z organu na przenosnik odstawiajacy urobek z wyrobiska. Organ zaopatrzony na przyklad w dwa ladujaoe platy przekazuje przy jego pelnym obrocie dwie porcje urobku na przenosnik. Zasto¬ sowanie w nim dwóch krótkich dodatkowyoh platów spowoduje, ze na jeden obrót organu dostar- ozany bedzie urobek na przenosnik w czterech porcjach. Rozwiazanie to zmienia wlasciwosci organu Jako urzadzenia slimakowego transportowego, ale nie ma wplywu na proces urabiania oalizny• Organ wedlug wynalazku ma pomocnicze ladujace platy równej wysokosci z ladujacymi pla¬ tami, przy ozym pomocnicze platy sa usytuowane po stronie czolowej tarczy organu i sa zaopa¬ trzone w urabiajace noze. Noze na pomocniczym ladujacym placie sa ustawione z przesunieciem o pól podzialki w stosunku do nozy na poprzedzajacym go placie, liczao platy zgodnie z kie¬ runkiem obrotu organu. Na nastepnym placie noze sa ustawione na tej samej linii skrawania, 146 8822 146 882 oo noze na pomocniczym ladujacym plaoie. W szczególnym wykonania organ ma na pornooniczy oh platach obrotowe noze, a na ladujacy oh plataoh promieniowe noze.Organ urabiajacy wedlug wynalazku nadaje sie do urabiania wegli zwiezlych i wegli z ka¬ miennymi przerostami dzieki zwiekszonej liczbie nozy od strony czolowej tarczy, co jest mozliwe przez zastosowanie pomocniczych ladujacych platów uzbrojonych na krawedzi w urabia- jaoe noze. Ta czesc organu pracuje bowiem w obszarze pokladu w jego glebi, gdzie wegiel jest nieodprezony. Hatorniast w obszarze pokladu od strony czola sciany organ ma mniejsza liczbe nozy, oo jest wystarczajaoe, gdyz jest to obszar wegla czesciowo odprezonego ze wzgledu na sasiedztwo z czolem solany* Do tej czesci organu nie siegaja juz pomocnicze la- dujaoe platy, ozyli zwiekszyla sie przestrzen miedzy platami ladujacymi. W tej przestrzeni miesci sie wiec wiecej urobku, oo jest korzystne, gdyz w tym obszarze jest transportowany urobek uzyskany przez ozolowa czesc organu oraz urobek uzyskany w tylnej ozesoi organu. Za¬ razem w tylnej ozesoi organu przez brak w niej pornooniozyeh ladujacych platów maleje tarcic urobku, a przez to transport urobku odbywa sie sprawniej, ozyli takze szybciej. W organie wedlug wynalazku uzyskano zatem nie tylko korzystniejsze warunki urabiania fragmentem Olga¬ mi najbardziej zaglebionym w calizne, ale zarazem szybszy odplyw urobku i wiecej mlejsoa dla urobku w tylnym fragmenoie organu. Unika sie przez to równiez kruszenia urobku, a takze uzyskuje sie wiekszy wyohód grubszego sortymentu urobku zwlaszoza dzieki mniejszej liczbie nozy na obwodzie w ozesoi tylnej organu urabiajacego* Organ urabiajacy wedlug wynalazku przedstawiono w przykladzie wykonania na rysunku na którym fig. 1 jest rozwinieciem organu z nozami ustawionymi na tarczy czolowej w linii, fig. 2 jest rozwinieciem organu z nozami ustawionymi przemiennie, fig. 3 jest fragmentem widoku organu z nozami obrotowymi, a fig. 4 widokiem z boku noza obrotowego.Organ urabiajacy tworza czolowa taro za 2 1 transportuj aco-urabiajaca czesc 5. Transpor- tujaco-urablajaoa ozesc 5 organu tworza ladujaoe platy 8 zwiniete srubowo, przez co powsta¬ je trójwohodowy transporter slimakowy. Ladujaoe platy 8 rozciagaja sie na cala dlugosc oze¬ soi 5. Miedzy ladujaoyml platami 8 sa umieszczone pomocnicze ladujace platy 8a, które sa ulokowane od strony czolowej tarozy 2 i rozoiagaja sie na polowe dlugosci 6 transportujaco- ladujaoej ozesoi 5.

Cl.4 E21C 25/10 Creators inventions Jan Myrczek, Norbert Pioseczny, Rajmund Josko9 Michal Fele, Kazimierz Franozak, Stanislaw Orchel, Marek Baryoki The holder of the patent: Rybnicko-Jastrzebskie Weglowe Gwarectwo "Borynia" Stone Coal Mine, Jastrzebie Zdrój (Poleka) ORGAN FOR A SCREEN COMBINE The subject of the invention is the mining organ of a soybean harvester made of a hub in the cylinder phono, equipped with a front disc, and along the hub with a helical plinth, and the edges of the blades are attached with cutting knives. The organ is intended for the mining of compact coal and yielding scales occurring in stock. The working organ, known from the German patent specification No. 3,105,732, has an aluminum hub with a front disc, and on the sand it has landing plates coiled in a helical rope. These plates are of two kinds, some of them extend along the length of the hub and are provided with sharp blades on the outer edge. The second type of lobes, placed halfway between the lobes of the first type, extend from the edge of the hub to the half of its width and are situated in the body on the opposite side of the hub with respect to the Ozole disc. Their outer edge consists of a comb rising from the surface of the hub to the height of the remaining plates, and adjacent to the edge of the hub these plates have a constant height. This organ has been equipped with additional, short plates in order to obtain a more even flow of the spoil from the organ onto the conveyor which puts the spoil away from the excavation. The organ equipped with, for example, two loading plates, transfers two portions of the spoil to the conveyor at full rotation. The use of two short additional plates in it will cause that the spoil will be delivered to the conveyor in four portions for one revolution of the drum. This solution changes the properties of the organ as a conveyor auger, but does not affect the process of mining the tube. • The organ according to the invention has auxiliary landing plates of equal height with landing plaques, while the auxiliary axes are located on the front side of the organ disk and are filled in carving knives. The knives on the auxiliary loading plate are positioned half-graduated with respect to the knives on the preceding plate, counting the plates according to the direction of rotation of the organ. On the next plate, the knives are positioned on the same cutting line, 146 8822 146 882 about the knives on the auxiliary landing beach. In a special embodiment, the organ has rotating knives on the lobes of the plata, and radial knives on the plataoh. The mining organ according to the invention is suitable for the production of coals and lumpy coals due to the increased number of knives on the front side of the disc, which is possible by the use of auxiliary landing plates armed on the edge with working knives. This part of the organ works in the area of the deck in its depth, where the coal is not impregnated. Hatorniast in the area of the deck on the front side of the wall, the organ has a smaller number of knives, o it is sufficient, because it is a partially relaxed carbon area due to the vicinity of the brine forehead * There are no auxiliary lathes to this part of the organ anymore, the space has increased between the loading plates. In this space there is more spoil, oo it is advantageous, because in this area the spoil obtained by the salt part of the organ and the spoil obtained in the back of the organ are transported. At the same time, in the back of the organ, the friction of the spoil is reduced due to the lack of pornoniosis of the landing plows, and therefore the transport of the spoil is more efficient, they also recover faster. Thus, in the organ according to the invention, not only more favorable mining conditions were obtained with the Olga fragment deepest in the body, but also faster outflow of the spoil and more soil for the excavated material in the rear fragment of the organ. This also avoids crushing the excavated material, and also obtaining a greater yield of a coarser variety of excavated material, especially due to the smaller number of knives on the perimeter of the rear edge of the cutting head * The cutting head according to the invention is shown in the example in the drawing in which positioned in line on the front disk, Fig. 2 is an expansion of the drum with alternating knives, Fig. 3 is a fragment of the view of the drum with rotary knives, and Fig. 4 is a side view of a rotary knife. The cutting organ creates a front blade for 2 1 transporting Urabiajaca part 5. Transporting and cutting the leg 5 of the organ is formed by a ladder plate 8 coiled helically, thus creating a three-tube screw conveyor. Ladujaoe lobes 8 extend the entire length of the soybean 5. Between the ladujaoyml lobes 8 are placed auxiliary landing lobes 8a, which are located on the front side of the taroza 2 and extend half the length of the 6 transporting-ladder plates 5. The distance between the landing plates is 10. 8 auxiliary ladujaoe plates 8a divide preferably in half, forming a parathyroid fragment 9 of the organ. The organ is equipped with knife handles 3 attached to the ozol taroza 2 and to the outer edges of the loading plates 8 and to the outer edges of the landing plates 8a. The knife holders 3 are equipped with rotating knives 1 or radial knives 1b arranged on the cutting lines 4. In the embodiment shown in Fig. 1 and Fig. 2, the knives 1 or 1b mounted on the landing plates 8 are spread out on the same cutting edges. 4, while the knives 1 or 1b mounted on the auxiliary plates 8a are arranged on the cutting lines 4 shifted by half a division with respect to the cutting line 4 knives on the plates 8. In a special embodiment of the head with rotating knives 1, according to Fig. 3, the knives 1 on the north beach 8a are spaced on the cutting lines 4 shifted by a half of a division to the cut line 4 knives 1 on the preceding beach 8, and knives 1 on the next beach 8 lie on the same cutting lines 49 knives on the pornographic beach 8a. Rotary Hoze 1 have axes 13 deviating from the cutting line 4 by angle {and in the direction of Ozole Tarose 4. Angle (and is most preferably 6 °, oo prevents the organ from being exhausted when the organ is equipped with knives with conical or lenticular blades On the front target plate 2 radial knives 1b are positioned in the lines inclined towards parts 5, so that the lines of the knives 1b_ on the lead plate 2 converge with the line of knives 1b arranged on the landing plate 8, together forming a wedge contour. deviating from the cutting line 4 by an angle from -15 ° to + 15 ° Rotating knives 1 are positioned on the base blade 2 also deviating them from the cutting line by an angle of -15 ° to 45 °, distributing them evenly. 4, the rotating knives 1 are mounted in the holders 3 with a projection above the handle. The hoops are also inclined at an angle fJL to a straight 16 polygonal to the knife trajectory line 12 resulting from the rotary movement around the axis of rotation 7 and the progressive rotation of the knife. direction 14. The angle JL is 43 ° to 45 ° for rotary knives. In the body according to the invention, designed for particularly difficult cutting conditions, the loading plate is to be assisted with the loading plate 6a is equipped with rotary knives 1, and the loading plate 8 is provided with radial knives 1b. 146 682 5 Claims Patent 1.
