(54) Nůž pro rozpojování hornin(54) Rock disintegrating knife
Vynález řeší nůž pro rozpojování hornin.The invention solves a rock breaking knife.
Dosud známé řezné nástroje razících a dobývacích kombajnů mají různé tvary i velikost, ale jsou nedokonalé v tom, že jejich nejvíce namáhavé části, tj. břity, ve tvaru kužele s ostrým nebo zakulaceným vrcholem, ve tvaru dláta s rovnými nebo zaoblenými plochami jsou málo odolné proti působení dynamických sil, které vznikají zejména při rozpojování těžce rozpojitelných hornin.Known cutting tools for punching and quarrying combines have different shapes and sizes, but are imperfect in that their most strenuous parts, i.e., cones in the form of a cone with a sharp or rounded apex, in the shape of a chisel with flat or rounded surfaces, are less resistant against the influence of dynamic forces, which arise especially during the disintegration of hard-to-disintegrate rocks.
Účinkem dynamických rázů dochází často k destrukci nejvíce namáhaných částí břitu a následně k rychlé likvidaci celého nože často i nožových držáků, nejsou-li nože včas zaměněny za nové.Due to dynamic shocks, the most stressed parts of the cutting edge are often destroyed and consequently the entire blade, often the knife holders, is quickly destroyed if the blades are not exchanged for new ones in time.
Uvedené nedostatky odstraňuje nůž pro rozpojování hornin podle vynálezu, jehož podstata spočívá v tom, že v tělese nože je uložen břit ve tvaru koule, přičemž více než polovina břitu je uvnitř tělesa nože. Břit může být spojen s tělesem nože pevně, nebo kluzně. Nůž se může otáčet kolem podélné osy. Břit může být z tvrzeného materiálu. Kulovité těleso, které tvoří břit nože, má nejlépe koncentrovanou hmotu ze všech těles a může proto lépe odolávat dynamickým rázům, než ostré nebo mírně zakulacené břity současných řezných nástrojů razících a dobývacích kombajnů.These drawbacks are overcome by the rock disintegrating knife according to the invention, characterized in that a knife-shaped blade is housed in the knife body, with more than half of the blade inside the knife body. The cutting edge can be fixed or slidingly connected to the blade body. The blade can rotate about the longitudinal axis. The blade may be of a hardened material. The spherical body, which forms the cutting edge of the knife, has the best concentrated mass of all bodies and can therefore better withstand dynamic shocks than the sharp or slightly rounded cutting edges of current cutting tools for punching and quarrying harvesters.
Na přiložených obr. 1 a 2 jsou schematicky znázorněny příklady provedení nože s břitem ve tvaru koule podle vynálezu.1 and 2 show schematically exemplary embodiments of a knife with a ball-shaped blade according to the invention.
Nůž pro rozpojování hornin podle vynálezu představuje na obr. 1 tangenciálně otáčivý nůž kolem podélné osy 3 s břitem 1 ve tvaru koule, který je s tělesem 2 nože pevně spojen.The rock disintegrating knife according to the invention in FIG. 1 represents a tangentially rotatable knife about a longitudinal axis 3 with a ball-shaped lip 1 which is fixedly connected to the knife body 2.
Na obr. 2 je schematicky znázorněn nůž s břitem ve tvaru koule, který je vložen do vybrání tělesa nože kluzně, a proto se břit 1 může při činnosti nože v hornině v libovolném směru pootáčet. Více než polovina břitu 1 ve tvaru koule je uvnitř tělesa . 2 nože.FIG. 2 shows schematically a knife with a blade in the shape of a ball, which is inserted into the recess of the knife body slidingly, and therefore the blade 1 can rotate in any direction during operation of the knife in the rock. More than half of the ball-shaped blade 1 is inside the body. 2 knives.
