  • Publication number: 20200113396
    Abstract: A plate system converts a wheelbarrow to a receptacle for a vacuum device. The plate system includes a vacuum plate body, an intake port, an exhaust port, and a vacuum pump mounted to the vacuum plate body. The vacuum plate body has an upper surface, a lower surface, and a resilient gasket on the lower surface of the vacuum plate body around a perimeter of the vacuum plate body to form a seal between the upper perimeter of the wheelbarrow body and the lower surface of the vacuum plate body when the vacuum plate system is on the wheelbarrow body. The resilient gasket covers an area of the lower surface of the vacuum plate body sufficient to fit over the upper perimeter of a plurality of wheelbarrows having open bodies in a range of sizes.

  • Patent number: 10582819
    Abstract: A vacuum plate converts a conventional wheelbarrow into a wet and dry dual purpose vacuum cleaner receptacle. Collection of fluids and solids directly into a wheelbarrow simplifies larger cleaning tasks, small flood remediation, transport of bulk particulate materials such as sand, pea stone, and mulch, and allows hydro-excavation to be carried out in home improvement and small scale professional landscaping projects. A fluid level sensor prevents the wheelbarrow from overflowing when collecting large quantities of fluid, and a sump pump allows fluids to be drained from collected slurries, leaving only solids in the wheelbarrow for reuse or independent disposal.
