[0002] Stadium marking machines are essential sports equipment when schools hold activities. The earliest marking tools for stadiums were ash spoons and ash buckets. These tools are relatively primitive, and the lines can only be controlled by the operator's experience. Later, roller-type marking machines and funnel-type marking machines appeared. Both roller-type marking machines and funnel-type marking machines include a box with a handle, an ash outlet at the bottom of the box, and a wheel parallel to the box is rotatably installed on the box. When marking, white lime is placed in the box, and the handle is pushed to rotate the wheel. The rotation of the wheel drives the box to move.
