<p>Rotating disc-shaped sweep construction as an extension part for weed mowers for removing plant remains, weeds, or dirt from paved surfaces, consists of disc (small brush disc) with pick-up spaces and formed by milling out from a thin cylindrical disc with outer diameter D1 and height H1. The disc is also called a small brush plate, in which as pick-up spaces, quadrangular recesses are milled out. Rotating disc-shaped sweep construction as an extension part for weed mowers for removing plant remains, weeds, or dirt from paved surfaces, consists of disc (1) (small brush disc) with pick-up elements or spaces, in which in each pick-up element a cover (3) can be slid and fixed, the cover on its turn being clamped on a wire bundle (4) for forming the rotating sweep construction and in which locking the cover can be done by a retaining pin mounted through a wall of the pick-up element or space and falling in a corresponding bore of the cover with wire bundle. The disc with pick-up spaces is formed by milling out from a thin cylindrical disc with outer diameter D1 and height H1. The disc is also called a small brush plate, in which as pick-up spaces, quadrangular recesses are milled out for the receipt with little clearance of quadrangular cover with wire bundle in an angle alpha with the horizontal. The quadrangular recesses or pick-up spaces have a side of D2 and a depth H2, in which H2 is less than H1. The springy extendible retaining pin with bolt or nut head is applied radially from a central polygonal recess with inscribed circle with diameter D3 and a depth H3 and is adjustable with regard to the insert length retaining pin, in which H2 greater than H3 but less than H1. The central polygonal recess has a central through bore with diameter D4 for mounting to the weed mower. The material of the thin cylindrical disc has a high tensile strength and elastic modulus and is well mechanically processable.</p> |
