Abstract

A beach cleaning apparatus comprises a forward assembly operatively connected to a trailer member, the forward assembly having a body portion rollably supported on a pair of spaced wheels and adapted for connection to a towing vehicle. A vertical member rotatable about a vertical axis extends upwardly from the body portion and has a rearwardly extending lever arm assembly pivotably secured thereto for movement about a horizontal axis. A winch on the forward assembly is connected to the lever arm assembly for effecting pivotal movement thereof. The free ends of the lever arm assembly are connected to the forward end of the trailer member, which consists of a rectangular container having a bed which comprises an interchangeable screen member adjacent its forward end and an interchangeable ground engaging blade member extending outwardly of the forward end. The trailer member is rollably supported on a pair of spaced wheels at the rear thereof, with the winch and lever arm assembly effecting vertical movement of the forward end thereof. A rotating brush extends transversely of the trailer member intermediate the blade member and screen member for driving sand and debris onto the screen member.

Dependent claims

A beach cleaning apparatus comprising a forward assembly and a trailer member operatively connected thereto, said forward assembly comprising a body portion, means on the forward portion of said body portion for securing the beach cleaning apparatus to a motorized vehicle, and first rotatable means extending transversely of said body portion for rollably supporting said forward assembly on the ground;

said trailer member comprising a bed comprising screen means adjacent the forward end thereof and having ground engaging means extending outwardly of said forward end, upstanding walls extending about the periphery of and mounted to said bed with the lower edge of the wall portion disposed adjacent said forward end of said bed beng spaced upwardly therefrom to provide a transversely extending opening, and second rotatable means extending transversely of the rear portion of said trailer member for rollably supporting said trailer member on the ground;
and lift means operatively interconnecting the forward portion of said trailer member to said forward assembly for raising and lowering the forward portion of said trailer member to disengage and engage said ground engaging means with sand to be cleaned whereby engaged sand passes over said ground engaging means as the beach cleaning apparatus moves forwardly, through said opening and onto said screen means where it undergoes a sifting action to remove debris therefrom, the sand thereafter passing downwardly through said screen means onto a beach or the like.

A beach cleaning apparatus comprising a forward assembly and a trailer member operatively connected thereto, said forward assembly comprising:

A. a body portion;
B. means on the forward portion of said body portion for securing the beach cleaning apparatus to a motorized vehicle;
C. first rotatable means extending transversely of said body portion for rollably supporting said forward assembly on the ground;
D. a vertical member extending upwardly from and mounted on said body portion intermediate the width thereof;
E. elongated lever arm means pivotably mounted at one end thereof to said vertical member at a point spaced upwardly from said body portion for pivotal movement about a horizontal axis;
F. mounting means at the other end of said lever arm means for pivotably securing said trailer member thereto for relative pivotal movement about a horizontal axis;
and
G. elevating means on said forward assembly operatively connected to said lever arm means for effecting pivotal movement thereof;
said trailer member comprising:
H. a rectangular bed comprising screen means adjacent the forward end thereof and having ground engaging means extending outwardly of said forward end;
I. upstanding wall members extending about the periphery of and mounted to said bed with the lower edge of the wall member adjacent said forward end of said bed being spaced upwardly therefrom to provide a transversely extending opening;
J. second rotatable means extending transversely of the rear portion of said trailer member for rollably supporting said trailer member on the ground;
K. third rotatable means extending transversely of said trailer member rearwardly of and adjacent said opening, the circumferential edges of said third rotatable means contacting said bed during rotation thereof whereby sand and debris passing through said opening is engaged by said third rotatable means and driven rearwardly onto said screen means, and drive means for effecting rotation of said third rotatable means;
and
L. coupling means adjacent the forward end of said trailer member cooperating with said mounting means on said lever arm means to releasably secure said trailer member to said lever arm means.
