The invention discloses a lower limiting device of a bulk machine. The bulk machine comprises a bulk head and a winding device; the bulk machine can adapt to loading of vehicles with different heights; a dust collection cover is always located at the optimal position, dust is gathered together, dust overflow is reduced, the dust removal effect is improved, and the bulk machine is more environmentally friendly; the bulk head is of a telescopic structure, the dust collection cover is arranged at the lower end of the bulk head, and lifting of the bulk head is driven by the winding device; the winding device comprises a first movable pulley, a steel wire rope, a fixed pulley and a winch, wherein the first movable pulley is installed on the lower portion of the bulk head; the fixed pulley is installed on the portion, above the bulk head, of a rack; the first movable pulley, the fixed pulley and the winch are connected through the steel wire rope; the steel wire rope between the winch and the fixed pulley is provided with a second movable pulley; the second movable pulley is hinged to a base of the winch through a balance weight support; a balance weight block is hung on the second movable pulley; and an infrared sensor is installed below the balance weight block. The bulk machine can adapt to the loading of the vehicles with different heights, and the dust removal effect is improved.
