The invention discloses mechanical equipment used for speed production and dust removal. The mechanical equipment comprises a dust removal room, a charge hole and an equipment bracket, wherein the lower end of the dust removal room is equipped with the equipment bracket; the left side of the equipment bracket is equipped with a roller motor; the left end of the roller motor is connected with a roller motor belt wheel through a motor shaft; the roller motor belt wheel is connected with a roller belt wheel through a roller belt; a roller rotary shaft is mounted on the roller belt wheel; and theright end of the roller rotary shaft penetrates through the right side wall of the dust removal room, and is rotatably connected with a supporting rod. The mechanical equipment is reasonable in structure; after the equipment is started, seeds with dust enter the dust removal room; a roller rotates, so that the seeds and the dust fly off; a gas inlet fan above the equipment is used for continuouslyblowing gas to the seeds in the equipment through a gas inlet, so that the seeds and the dust are sufficiently separated; a dust collecting device of the equipment is positioned on the upper part ofthe equipment, and a dust collecting area is relatively great; and the air movement principle is reasonably utilized, so that dust is sufficiently and effectively absorbed.
