The invention relates to a thin seam short-span coal mining machine swing arm shell, a main body of the shell is an arm frame extending left and right, a transmission cavity used for installing a cutting transmission mechanism is arranged in the arm frame, and the left end and the right end of the arm frame are respectively a high-speed end and a low-speed end. An input end gear mounting hole and an output end gear mounting hole are formed in the rear portion of the high-speed end of the arm frame and the low-speed end of the arm frame respectively, a connecting arm overhanging forwards from the arm frame is arranged in the middle of the arm frame, and a front arm overhanging leftwards or rightwards from the connecting arm is arranged on the connecting arm. The front parts of the high-speed ends of the front arm and the arm frame are respectively provided with a front pin shaft mounting hole and a rear pin shaft mounting hole which are used for mounting the cutting motor as a pin shaft; and the front pin shaft mounting hole, the rear pin shaft mounting hole and the input end gear mounting hole are coaxial. According to the invention, a larger mining range and larger cutting power can be provided, the machine body can be shortened, and the gravity center of the coal mining machine can be improved.

The invention provides a coating for lost foam casting. The coating is prepared from the following raw materials by weight percent: 40%-47% of water glass with the modulus of 2.0-2.5, 52-59% of bauxite with the granularity of 62-74 microns or silica sand with the granularity of 62-74 microns, not more than 0.2% of emulsifier op-10, and 0.95% of phenolic resin liquid. The application method of the coating for lost foam casting comprises the following steps of: firstly, mixing the water glass, the emulsifier op-10 and the phenolic resin liquid together, and then adding the bauxite or the silica sand, and stirring all the materials evenly; then painting a lost foam module with the mixture pass by pass while drying; drying after the last pass of painting, and then cooling to room temperature; roasting the lost foam module; preserving heat at a temperature not lower than 400 DEG C; after burying the lost foam module in a box, carrying out slight vibration and then performing casting molding. The coating for lost foam casting can be used for solving the problems of recarburization, pore formation and slag inclusion in the lost foam casting process; the application time from coating painting to completion of roasting is reduced to not more than 32 hours from previously at least 48 hours; besides, the coating is excellent in high temperature resistance, high in shell mould strength and excellent in moulded shell collapsibility; the cost can be reduced by **-**.
