[0017] Example: The invention has a built-in water cooling and dust removal device for the oil tank of a roadheader, such as figure 1 , figure 2 As shown, it includes an oil tank 1, a serpentine copper tube cooler 2, two high-pressure articulated joints 3, a ball valve 4, a hose 8; 9; 10, a water pressure safety valve 5, a water spray bracket 6 and a scraper conveyor 7. The serpentine copper tube cooler 2 is built in the oil tank 1. The serpentine copper tube cooler 2 cools the hydraulic oil through heat exchange between the flowing cooling water and the hydraulic oil in the oil tank 1. The serpentine copper pipe in the spool is arranged in the oil tank 1, so the contact area with the hydraulic oil is large, the cooling water can fully exchange heat with the hydraulic oil, and the cooling efficiency is higher; the high-pressure articulated joint 3 is installed in the The serpentine copper tube cooler 2 extends out of the nozzle of the oil tank 1, and the pipeline direction of t...
