Description

Przedmiotem wynalazku jest organ urabiajacy do kombajnów weglowych lub innych maszyn do urabiania skal majacy .postac organu obrotowego.The subject of the invention is a mining organ for coal harvesters or other machines mining scales in the form of a rotating body.

Znane sa benowe organy urabiajace z bebnami osadzonymi na wale napedzanym i zaopatrzonymi na obwodzie w sztywno osadzone noze. Ich dzia¬ lanie skrawajace, podobne do dzialania glowicy frezowej, w bardzo malym stopniu wykorzystuje lupliwosc i kruchosc zloza skaly. Dlatego usilo¬ wano rozwiazac bebnowy organ urabiajacy, którego narzedzia urabiaja dzialajac udarowo i'powodujac raczej odlupywanie niz skrawanie. Wszystkie te znane bebnowe ongany urabiajace wykazaly liczne wady.Gas cutting organs with drums are known mounted on a driven and equipped shaft around the perimeter of rigidly mounted knives. Their department cutting cast, similar to the operation of a head cutter, uses very little the lumpiness and brittleness of the rock deposit. So try hard it was important to dismantle the reel mining organ which the tools work with an impact and cause chipping rather than cutting. All those the well-known cutting drums have shown many disadvantages.

W wyniku skrawania uzyskuje sie skaly roz¬ drobnione, a jak wiadomo, o wiele bardziej ce¬ nione sa grube sortymenty. Organy urabiajace o dzialaniu udarowym wykazaly liczne wady. Prze¬ de wszystkim wymagaja one bijaków o duzej masie, krusza odlupane bryly skal i przy tym ulegaja szybkiemu zuzyciu.By cutting, a scale of distribution is obtained fine, and as you know, much more expensive there are thick stocks. The mining organs of Fr. the impact action showed numerous disadvantages. Trans most of all, they require longer rams mass, crumbles chipped rock solids and at the same time they wear out quickly.

Celem wynalazku jest wyeliminowanie wyzej wymienionych wad. Cel ten zostal osiagniety za pomoca organu wedlug wynalazku, który zao¬ patrzony jest w narzedzia urabiajace w postaci niesymetrycznych dysków obrotowych, których u- lozyskowanie znajduje sie ponizej zewnetrznego zarysu elementu ladujacego organu urabiajacego.The object of the invention is to eliminate the above mentioned defects. This goal was achieved for by means of an organ according to the invention which was established by is looked at the cutting tools in the form unsymmetrical rotating disks whose u- the bearing is located below the outer the outline of the loading element of the cutting drum.

Przy czym plaszczyzny obrotu dysków moga byc usytuowane pod róznym katem w stosunku do osi organu urabiajacego w zaleznosci od urabianej skaly.The plane of rotation of the disks may be located at different angles to the axis the cutting head depending on the cut rocks.

Beben urabiajacy wedlug wynalazku jest uwi- doczniony w przykladowym rozwiazaniu na rysun¬ ku, którego fig. 1 przedstawia organ urabiajacy w widoku z boku, fig. 2 przedstawia ten organ w widoku z tylu. Organ urabiajacy stanowi be¬ ben slimakowy 5 do którego ponizej zewnetrznego io obrysu 3 elementu ladujacego 4 przymocowane sa oprawy lozyskowe 2 w których ulozyskowane sa narzedzia urabiajace 1 majace postac niesymetrycz¬ nych dysków obrotowych.According to the invention, the cutting drum is shown in an example solution in the drawing towards which Fig. 1 shows the cutting head in side view, figure 2 shows this organ in the rear view. The mining organ is the beech snail ben 5 to which below the external and the outline 3 of the charging element 4 are attached 2 bearing housings in which are located the cutting tools 1 having an asymmetric form rotating disks.

Beben urabiajacy wedlug wynalazku pozwala na urabianie skal w postaci grubych bryl przy zmniejszonym zapyleniu. Narzadzia urabiajace w postaci niesymetrycznych krazków pozwalaja na znaczne zmniejszenie oporów urabiania a tym sa¬ mym na zwiekszeniu urabiania. According to the invention, the mining drum allows for the cutting of rocks in the form of thick lumps at reduced dustiness. Tools for cutting v the form of unsymmetrical discs allows for significant reduction of the cutting resistance and thus my to increase the mining.
