Abstract

spreader of the present invention seeks to solve problems of having a single rotor to improve distribution, distribution rate and the amount of material the spreader can distribute and comprises a frame, a hopper connected to the frame and configured to contain granular material to be spread over terrain or other surfaces, two wheels rotatably connected to the frame and a first rotor and a second rotor rotatably connected to the frame below the hopper and configured to spread the granular material. The first and second rotors rotate in opposite directions and independently of each other and a gear system is constructed to drive the first and second rotors. The gear system receives input from at least one wheel of the two wheels. Two square openings are disposed in the lower portion of the hopper such that each of the two openings is located over a different one of the first and second rotors. Each opening is configured to allow the flow of granular material, by gravity, from the hopper onto the different one of the first and second rotors. A first agitator is connected to the first rotor and is configured to facilitate the flow of the granular material from the hopper onto the first rotor. A second agitator is connected to the second rotor and is configured to facilitate the flow of the granular material from the hopper onto the second rotor. A gear assembly is connected to one of the first agitator or the second agitator. A stepper motor is connected to the gear assembly and is configured to generate an amount of current as a function of rotational movement received from the gear assembly. An integrated logic circuit is communicatively coupled to the stepper motor. The integrated logic circuit is configured to: (i) measure the amount of current generated by the stepper motor, (ii) compare the measured amount of current to a reference amount of current, and (iii) determine, based on the results of the comparison, feedback to provide to a user regarding a linear velocity of spreader.

Claims (16)

CLAIMS :
1. A spreader, comprising: a frame; a hopper connected to the frame and configured to contain granular material to be spread over terrain or other surfaces; two wheels rotatably connected to the frame; a first rotor and a second rotor rotatably connected to the frame below the hopper and configured to spread the granular material, wherein the first and second rotors rotate in opposite directions and independently of each other; a gear system constructed to drive the first and second rotors, the gear system receiving input from at least one wheel of the two wheels; two square openings disposed in the lower portion of the hopper such that each of the two openings is located over a different one of the first and second rotors, each opening being configured to allow the flow of granular material, by gravity, from the hopper onto the different one of the first and second rotors; a first agitator connected to the first rotor and configured to facilitate the flow of the granular material from the hopper onto the first rotor; a second agitator connected to the second rotor and configured to facilitate the flow of the granular material from the hopper onto the second rotor; a gear assembly connected to one of the first agitator or the second agitator; a stepper motor connected to the gear assembly and configured to generate an amount of current as a function of rotational movement received from the gear assembly; and an integrated logic circuit communicatively coupled to the stepper motor, the integrated logic circuit configured to: (i) measure the amount of current generated by the stepper motor, (ii) compare the measured amount of current to a reference amount of current, and (iii) determine, based on the results of the comparison, feedback to provide to a user regarding a linear velocity of spreader.
2. The spreader of claim 1, further comprising an indicator, located so as to be visible to the user and configured to provide the feedback to the user.
3. The spreader of claim 2, wherein the indicator comprising three lights, the three lights each indicate the linear velocity of the spreader relative to a predetermined linear velocity.
4. The spreader of claim 3, wherein the three lights comprise red, green, and red lights.
5. The spreader of claim 2, wherein the feedback comprises an indication that the linear velocity of the spreader is too fast, too slow, or within a reference acceptable range.
6. The spreader of claim 1, further comprising a holder for holding a portable electronic device, the holder being located such that it is accessible to the user while using the spreader.
7. The spreader of claim 1, wherein the wheels are made of a foam rubber material.
8. The spreader of claim 1, wherein the granular material comprises any of ice melting granules, fertilizer, pesticides, herbicides, granular soil amendment material, granular oil absorbent material, dusting products, granular floor cleaning product, or grass seed.
9. The spreader of claim 1, further comprising two additional square openings disposed in the lower portion of the hopper such that each of the two additional square openings is located over a different one of the first and second rotors, each additional square opening being configured to allow the flow of granular material, by gravity, from the hopper onto the different one of the first and second rotors.
10. The spreader of claim 1, further comprising a first moveable deflector and a second moveable deflector configured to block at least a portion of the granular material ejected by the first and second rotors, the first moveable deflector rotates in a first direction and is configured to block at least a portion of the first rotor when activated, the second moveable deflector rotates in a second direction and is configured to block at least a portion of the second rotor when activated.
11. The spreader of claim 10, wherein the first moveable deflector comprises a first gear portion; and the second moveable deflector comprises a second gear portion configured to engage with the first gear portion of the first moveable deflector such that rotation of first moveable deflector in the first direction causes the second moveable deflector to rotate in the second direction.
12. The spreader of claim 10, wherein the first moveable deflector and the second moveable deflector are moveable between at least a first position and a second position.
13. The spreader of claim 10, wherein the first moveable deflector blocks at least a portion of the first rotor when activated and the second moveable deflector blocks at least a portion of the second rotor when activated.
14. The spreader of claim 13, wherein the portion of the first rotor blocked by the first moveable deflector is larger than the portion of the second rotor blocked by the second moveable deflector.
15. The spreader of claim 10, further comprising a deflection activation lever connected to the first moveable deflector, the deflection activation lever configured for selective activation of the first and second moveable deflectors.
16. A spreader according to claim 1, substantially as herein described or exemplified with reference to any one of the accompanying drawings.
