Abstract
A magnetic sweeper includes a mounting frame with left and right side walls, a rotating shaft with ends journalled in the left and right side walls, and a cylindrical body rotated with and surrounding the rotating shaft. A plurality of permanent magnets are disposed in a circumferential wall of the cylindrical body and define uppermost and lowermost magnetic linear limits. A guiding member, formed from a non-magnetic material, is secured to the left and right side walls, and includes a major wall with leading and tailing ends that are respectively spaced non-equidistantly from the uppermost and lowermost magnetic linear limits. A collecting member is disposed downstream of and below the uppermost magnetic linear limit for receiving magnetic metal objects captured by means of the permanent magnets. A mounting axle is disposed on the mounting frame and is spaced apart from the rotating shaft for mounting of a wheel member. A coupling member is provided to transmit rolling movement of the wheel member to the rotating shaft for rotating the cylindrical body.
