Abstract
Układ zraszania strefy urabiania skał nożami styczno-obrotowymi zwłaszcza z ostrzami słupkowymi do urabiania skał i węgla kamiennego, wyposażony w nóż z ostrzem osadzonym w części roboczej trzonka noża (oprawie ostrza) oraz częścią chwytową trzonka noża mocowaną w uchwycie nożowym połączonym z instalacją wodną charakteryzuje się tym, że część chwytowa (1) trzonka noża na całej długości posiada spiralne kanały (6) wykonane pod kątem β w granicach 30 ÷ 65° i łączące się z obwodowym wybraniem (14) w kołnierzu oporowym części roboczej (2) trzonka noża (oprawy ostrza), przy czym wybranie (14) połączone jest z co najmniej jednym wzdłużnym, przelotowym otworem (15) zakończonym dyszą zraszającą (13).The system of sprinkling the rock mining zone with tangential-rotating knives, especially with bar blades, for mining rocks and hard coal, equipped with a knife with a blade embedded in the working part of the knife shaft (blade holder) and the gripping part of the knife shaft mounted in the knife holder connected to the water installation, is characterized by in that the gripping part (1) of the knife shaft along its entire length has spiral channels (6) made at the angle β in the range of 30 ÷ 65° and connecting with the circumferential recess (14) in the stop collar of the working part (2) of the knife a blade), wherein the recess (14) is connected to at least one longitudinal, through hole (15) ended with a spray nozzle (13).
