Title:
NEGATIVE-PRESSURE SUCTION SYSTEM USED FOR RESIDUES AT BOTTOM OF CONTAINER AND HAVING MOVABLE SUCTION HEAD
Document Type and Number:
WIPO Patent Application WO/2023/103608
Kind Code:
A1
Abstract:
A negative-pressure suction system used for residues at the bottom of a container and having a movable suction head, the negative-pressure suction system at least comprising a dust suction and collection device (1), a dust suction pipeline (2), a movement device (3) and a moving suction head device (5), wherein first pulleys (509) are provided below a housing of the moving suction head device (5); second pulleys (510) are provided above an upper platform (551) of an in-parallel mechanism (55), and upper end universal joints (552) are provided below the upper platform (551); the upper end universal joints (552) are rotationally connected to lower end universal joints (554) by means of connecting rods (553), and the lower end universal joints (554) are arranged above a lower platform (555); a suction head (517) is mounted below the lower platform (555), and the suction head (517) is connected to the dust suction pipeline (2); one end of a steel wire rope (512) is connected to a boss, and the other end of the steel wire rope (512) passes through the first pulleys (509), the second pulleys (510) and the housing in sequence, and is then connected to the movement device; and the steel wire rope (512) is stretched or retracted by means of the movement device, so that the in-parallel mechanism (55) drives the suction head (517) to move in a horizontal plane. The negative-pressure suction system achieves a three-degrees-of-freedom motion of the moving suction head device, thereby solving the problem of it not being possible for a suction range to cover the whole area of the bottom of a container.
