Abstract:
A magnetic sweeper adapted to be rolled over a surface to pick up metal objects scattered thereon, said magnetic sweeper comprising:an elongated mounting frame including a front end, a rear end, a guide wall disposed at said front end, a barrier wall extending from said guide wall and disposed behind said guide wall so as to define cooperatively an axial hole therebetween that extends along a transverse direction of said mounting frame, and a bottom plate attached to and extending rearward from a lower end portion of said barrier wall, said guide wall having an upper end wall portion, a lower end wall portion, and an outer guide face that is disposed between said upper and lower end wall portions and that extends along a circumferential direction of said axial hole; a magnetically attracting wheel assembly disposed in said axial hole in said mounting frame and including a rotating shaft journal led in said axial hole, at least one magnetically attracting wheel sleeved fixedly on said rotating shaft, and a plurality of magnet units attached to said magnetically attracting wheel; a pair of rotating wheels mounted rotatably and respectively on two opposite sides of said mounting frame and rotatable relative to said mounting frame to rotate said magnetically attracting wheel within said axial hole so as to be adapted to magnetically attract the objects onto said guide face of said mounting frame, thereby moving the objects from said lower end wall portion to said upper end wall portion along said guide face, after which the objects drop from said upper end wall portion to said bottom plate of said mounting frame; and a universal caster mounted on said bottom plate of said mounting frame and cooperating with said rotating wheels so as to be adapted to support said mounting frame on the surface.
