The utility model discloses a detection device for a coal machine. The detection device for the coal machine comprises the coal machine, a coal seat is fixedly installed on the coal machine, a coal pipe is fixedly installed at the top of the coal seat, a coal feeding hopper is fixedly installed at the top end of the coal pipe, a linkage assembly and a detection assembly are arranged on the coal pipe, and an alarm is fixedly installed on the outer wall of one side of the coal seat. Through the arrangement of the linkage assembly and the detection assembly, the weight of coal extrudes a connecting plate, the connecting plate extrudes a telescopic rod and a first spring, the connecting plate can push a moving rod to drive a second spring to stretch, the moving rod pushes the moving plate to move on a fixed rod, and the moving plate extrudes a pressure sensor; the transmitter converts the received pressure into an electric signal and transmits the electric signal to the alarm, and when the pressure borne by the p
