Special drive system that provides automatic application control of granular material

Abstract

A special drive system that provides automatic and uniform application control of granular materials. It provides an automatic application control of a granular material from a granular material spreader and is comprised of (a) at least one electric motor for driving the conveyor and spinner at a speed, the said speed which determines a rate of discharge of the granular material; (b) a power source for the motor; (c) a means for controlling the power from the power source to the at least one motor; (d) a means for inputting a signal to the means for controlling the power; (e) a wiring harness with control and power electrical connectors; and (f) a means to mechanically mount the special drive system to the grain spreader wherein the result of the system is an accurately controlled rate of discharge and hence dispensing of the granular materials.

1 . A special drive system that provides an automatic application control of a granular material from a granular material spreader, the spreader including a hopper, a conveyor and a spinner device with a means for spinning at a desired speed and the said special drive system is comprised of:
 (a) at least one electric motor for driving the conveyor and spinner at a speed, the said speed which determines a rate of discharge of the granular material;   (b) a power source for the motor;   (c) a means for controlling the power from the power source to the at least one motor;   (d) a means for inputting a signal to the means for controlling the power;   (e) a wiring harness with control and power electrical connectors; and   (f) a means to mechanically mount the special drive system to the grain spreader   wherein the result of the system is an accurately controlled rate of discharge and hence dispensing of the granular materials.   
     
     
         2 . The system according to  claim 1  wherein the means for controlling is manual. 
     
     
         3 . The system according to  claim 2  wherein the manual means is a potentiometer. 
     
     
         4 . The system according to  claim 1  wherein the means for controlling is automatic. 
     
     
         5 . The system according to  claim 4  wherein the automatic means uses a software program with the input signal. 
     
     
         6 . The system according to  claim 5  wherein the inputting means is radar. 
     
     
         7 . The system according to  claim 5  wherein the inputting means is a Global Positioning System (GPS) that relates a position with other inputs. 
     
     
         8 . The system according to  claim 7  wherein the other inputs is a crop yield map. 
     
     
         9 . The system according to  claim 7  wherein the other inputs is a fertilizer usage map. 
     
     
         10 . The system according to  claim 1  wherein the means for spinning at a desired speed is a separate motor ( 31 B 1 ). 
     
     
         11 . The system according to  claim 1  wherein the means for spinning at a desired speed is mechanical linkage ( 31 B 2 ) to the conveyor. 
     
     
         12 . A process for accurately spreading a granular material for accurately spreading a granular material without an expensive hydraulic package, or the inherit inaccurate press wheel or ground wheel.
