Abstract

A granular spreader having a V-shaped hopper for distribution of oil absorbing granules can be used on race track spills. The granular spreader is towed by a vehicle such as a pickup truck during racing intervals. A rotatable scrubber is affixed to the hopper which can be lowered by an electric winch to contact the race track to urge the deposited granules into the spilled liquid. A pair of flexible flaps are affixed to the bottom of the hopper to assist in distribution and to prevent the fine granule particles from being blown away before contacting the spilled liquids. A cart is also provided for storing the granular spreader during periods of non-use.

Claims

1. A Granular spreader for attachment to a vehicle comprising:

a hopper, said hopper defining an egress;

a first flexible flap;

a second flexible flap, each of said first and second flaps attached to said hopper and extending along said egress the width thereof in opposing relation to allow granular material from said egress to pass therebetween during spreading;

a scrubber, said scrubber affixed to said hopper, a target, said target selectively slideable along said scrubber, said scrubber being pivotally joined to said hopper; and

a winch positioned on said hopper, said winch connected to said scrubber to raise and lower said scrubber.

2. The granular spreader of claim 1 further comprising an auxiliary spreader, said auxiliary spreader connected to said hopper.

3. The granular spreader of claim 1 further comprising a remote, said remote connected to said winch for operating the same.

4. The granular spreader of claim 1 further comprising a handle, a dispersion tube, said handle affixed to said dispersion tube to rotate said dispersion tube, said dispersion tube mounted proximate said egress.

5. The granular spreader of claim 1 wherein said hopper is V-shaped.

6. The granular spreader of claim 1 further comprising a scrubber frame, said scrubber frame attached to said hopper and to said scrubber.

7. The granular spreader of claim 1 further comprising a chain, said chain attached to said first flap for lifting the same.

8. The granular spreader of claim 7 wherein said second flap defines an opening, said chain passing through said opening.

9. The granular spreader of claim 6 further comprising a chain, said chain attached to said scrubber frame.

10. A granular spreader for attachment to a vehicle comprising:

a V-shaped hopper, said hopper defining an egress, a first flexible flap, a second flexible flap, each of said first and second flaps attached to said hopper and extending along said egress the width thereof in opposing relation to allow granular material from said egress to pass therebetween during granular spreading, a scrubber, said scrubber pivotally affixed to said hopper, a target, said target selectively slideable along said scrubber, a winch, said winch positioned on said hopper, said winch connected to said scrubber to raise and lower said scrubber, a remote, said remote connected to said winch, an auxiliary spreader, said auxiliary spreader connected to said hopper, a handle, a dispersion tube, said handle affixed to said dispersion tube to rotate said dispersion tube, said dispersion tube mounted proximate said egress.

11. The granular spreader of claim 10 further comprising a cart frame, a pair of adjustable side stanchions, said pair of side stanchions attached to said cart frame, a pair of side arms, one each of said pair of side arms affixed to one each of said pair of side stanchions, said pair of side arms supporting said hopper, a jack, said jack attached to one of said pair of side stanchions for raising said hopper, two pairs of wheels, each of said pairs of wheels attached to said frame.
