Full hydraulic drilling type coal mining machine for thin coal seam with large mining width

The invention discloses a full hydraulic drilling type coal mining machine for a thin coal seam with large mining width. The full hydraulic drilling type coal mining machine comprises an electronic control assembly, a hydraulic assembly, a host machine, a drilling tool assembly and a ventilating device, wherein a left hydraulic motor, a middle hydraulic motor and a right hydraulic motor are arranged at the tail end of a rack of the host machine in parallel; the drilling tool assembly comprises a left gear box, a middle gear box and a right gear box, which are arranged at the front end of the rack in parallel; two output shafts are respectively arranged on the left gear box and the right gear box; an output shaft is arranged on the middle gear box; the input shafts of the left gear box, the middle gear box and the right gear box are respectively connected with the output shafts of the left hydraulic motor, the middle hydraulic motor and the right hydraulic motor through a left-hand drill rod, a middle drill rod and a right-hand drill rod; and the ventilating device comprises an air inlet barrel and an air return barrel. The machine solves the defects of the existing drilling type coal mining machine that the mining width is limited, the drilling is easily blocked and gas and coal dust are easily gathered rapidly.
