Abstract
A method is provided. First and second carriers of a base are engaged with first and second tines of a fork of a loader, and the distribution box is lifted. A pneumatic pump is actuated with a hydraulic motor, and air is moved from the pneumatic pump through an ingress pipe to a valve housing and from the valve to a spreader bar through an egress pipe. A valve is actuated so as to mix the binder exiting the hopper with the air. The loader is moved along an unfinished surface while distributing the binder through the spreader bar onto the unfinished surface.
Claims19
An apparatus comprising:
- a hopper having:
- a substantially closed interior space that is configured to receive a binder;
- a fill assembly that is configured to be in fluid communication with the interior space of the hopper;
- and
- an exit port;
- a base that is secured to the hopper, wherein the base includes at least one carrier;
- a pneumatic pump that is secured to the hopper;
- an ingress pipe that is secured so as to be in fluid communication with the pneumatic pump and that is secured to the base;
- a valve housing that is secured to the ingress pipe and the exit port of the hopper, wherein the valve assembly is configured to be in fluid communication with the pneumatic pump;
- a valve that is secured within the valve housing, wherein the valve is configured to be pneumatically controlled;
- an egress pipe that is secured to the valve housing and that is secured to the base;
- and
- a spreader bar that is secured to the egress pipe.

A method comprising:
- engaging first and second carriers of a base of a distribution box with first and second tines of a fork of a loader;
- lifting the distribution box with the first and second tines of a fork;
- activating pneumatic pump with a hydraulic motor of the loader to generate pneumatic pressure;
- providing moving air from the pneumatic pump through an ingress pipe to a valve housing and from the valve to a spreader bar through an egress pipe;
- creating pressure on a binder at an exit port of a hopper by creating a gradient with a narrowing segment of the hopper;
- activating a valve secured to the valve housing at the exit port of the hopper so as to mix the binder exiting the hopper;
- moving the loader along an unfinished surface;
- and
- distributing the mixture of air and binder through the spreader bar onto an unfinished surface while moving.
6 more elements
An apparatus comprising:
- a base having a first area, wherein the base includes first and second carriers that each have a substantially rectangular cross-section and a length such that the first and second carriers are dimensioned to receive a tine of a fork, and wherein the first and second carriers are spaced apart from one another and are generally parallel to one another;
- a first outer wall that is secured along at least a first portion of the periphery of base;
- a second wall that is secured along at least a second portion of the periphery of the base;
- an inner support that is secured to the first and second carriers;
- a hopper having:
- an upper segment having a second area;
- and
- a lower segment having an upper end and a lower end, wherein the upper end of the lower segment is secured to the upper segment at a transition, and wherein the first outer wall is secured along a first portion of the transition, and wherein the second outer wall is secured along a second portion of the transition, and wherein the lower segment includes an exit port with a third area at the lower end of the lower segment, and wherein the third area is less than the second area, and wherein the inner support is secured to the lower segment;
- a valve housing that is secured to the exit port;
- a pneumatic pump;
- an ingress pipe that is secured between the pneumatic pump and the valve housing, wherein the ingress pipe is secured to the base;
- an egress pipe that is secured to the valve housing and the base;
- a valve that is secured with the valve housing, wherein the valve is configured to be pneumatically actuated;
- and
- a spreader bar that is secured to the egress pipe.
