Abstract
A hose-end spreader device includes a hopper configured to contain an amount of granular product, the hopper comprising a hopper inlet and a hopper outlet in communication with the hopper inlet. The device further includes a first chamber in communication with the hopper outlet, the first chamber comprising a first opening through which the granular product exits the device, and a first impeller disposed in the first chamber. Also included are a housing disposed below the first chamber, the housing comprising a fluid inlet, a second chamber in communication with the fluid inlet, and a second opening in communication with the second chamber through which a fluid exits the device, and a second impeller disposed in the second chamber. The second impeller is coupled to the first impeller.
Claims21
A hose-end spreader device, the device comprising:
- a hopper configured to contain an amount of granular product, the hopper comprising a hopper inlet and a hopper outlet in communication with the hopper inlet;
- a first chamber in communication with the hopper outlet, the first chamber comprising a first opening through which the granular product exits the device;
- a first impeller disposed in the first chamber;
- the first impeller comprising a plate and a plurality of blades;
- a housing disposed below the first chamber, the housing comprising a fluid inlet, a second chamber in communication with the fluid inlet, and a second opening in communication with the second chamber through which a fluid exits the device;
- and
- a second impeller disposed in the second chamber and being disposed below the first chamber and the first impeller and coupled to the first impeller;
- wherein the granular product and the fluid exit the device, separately from each other, at the first opening and the second opening, respectively.
A hose-end spreader device, the device comprising:
- a hopper configured to contain an amount of product, the hopper comprising a hopper inlet, a funnel, and a hopper outlet, the hopper outlet positioned at a bottom portion of the funnel and in communication with the hopper inlet;
- a first chamber in communication with the hopper outlet, the first chamber comprising a first opening through which the product exits the device;
- a first impeller disposed in the first chamber;
- a second chamber disposed below the first chamber, the second chamber comprising a second opening through which a fluid exits the device;
- a second impeller disposed in the second chamber, the second impeller being coupled to the first impeller;
- and
- wherein the first chamber and the second chamber are constructed to keep the product separated from the fluid while inside the device;
- wherein an axis of rotation of the first impeller is coincident with an axis of rotation of the second impeller;
- wherein, when the fluid moves through the second chamber and exits the second opening, movement of the fluid causes rotation of the first impeller and the second impeller, and rotation of the first impeller causes the granular product to exit the first opening;
- and
- wherein the axis of rotation of the second impeller is perpendicular to a flow of the fluid through the second chamber.
A hose-end spreader device, the device comprising:
- a hopper configured to contain an amount of product, the hopper comprising a hopper inlet and a hopper outlet in communication with the hopper inlet;
- a first chamber in communication with the hopper outlet, the first chamber comprising a first opening through which the product exits the device;
- a first impeller disposed in the first chamber, wherein the first impeller comprises a plate and a plurality of blades;
- a second chamber disposed below the first chamber, the second chamber comprising a second opening through which water exits the device;
- a second impeller disposed in the second chamber, the second impeller being coupled to the first impeller;
- and
- a fluid inlet in communication with the second chamber;
- wherein the device is constructed such that water flows through the fluid inlet into the second chamber, through the second chamber causing rotation of the first impeller and the second impeller, and out the second opening, exiting the device;
- wherein rotation of the first impeller causes the product to dispense from the first opening, exiting the device separate from the water;
- and
- wherein the product and water begin mixing at a distance at least four feet from the second opening.
