Abstract

In accordance with example embodiments, a system may include a first feeder configured to transport asphalt, a second feeder configured to receive the asphalt from the first feeder, and a controller configured to control a speed of the first feeder and the second feeder in response to an input from an operator.

Claims

exact text as granted — not AI-modified
What we claim is: 
     
         1 . A system comprising:
 a first feeder configured to transport asphalt;   a second feeder configured to receive the asphalt from the first feeder; and   a controller configured to control a speed of the first feeder and the second feeder in response to at least one of an input from an operator and a sensor.   
     
     
         2 . The system of  claim 1 , wherein
 the first feeder includes a first motor and the second feeder includes a second motor and the controller is configured to control the first and second motors.   
     
     
         3 . The system of  claim 2 , wherein the first motor is a hydraulic motor and the second motor is a hydraulic motor. 
     
     
         4 . The system of  claim 3 , wherein the first motor is controlled by first hydrostatic pump and the second motor is controlled by a second hydrostatic pump and the controller controls the first and second hydrostatic pumps to control the first and second hydraulic motors. 
     
     
         5 . The system of  claim 1 , wherein the controller is configured to substantially simultaneously increase and decrease speeds of the first and second feeders based on the input from the operator. 
     
     
         6 . The system of  claim 1 , further comprising:
 a third feeder configured to receive the asphalt from the second feeder, wherein the controller is further configured to control a speed of the third feeder in response to the input from the operator.   
     
     
         7 . The system of  claim 1 , further comprising:
 a third feeder configured to provide the asphalt to the second feeder, wherein the third feeder is controlled independently of the first and second feeders.   
     
     
         8 . The system of  claim 1 , further comprising:
 a first load sensor configured to measure a first load associated with the first feeder; and   a second load sensor configured to measure a second load associated with the second feeder, wherein the controller is further configured to control a speed of the first and second feeders based on at least one of the first and second loads.   
     
     
         9 . The system of  claim 8 , wherein the first feeder includes a first motor and the second feeder includes a second motor and the first load is a first pressure and the second load is a second pressure. 
     
     
         10 . The system of  claim 9 , wherein the first and second motors are hydraulic motors. 
     
     
         11 . A method comprising:
 moving asphalt with a first feeder;   moving the asphalt with a second feeder, the second feeder receiving the asphalt from the first feeder; and   controlling speeds of the first feeder and the second feeder by inputting an input to a controller.   
     
     
         12 . The method of  claim 11 , wherein
 the first feeder includes a first motor and the second feeder includes a second motor and controlling speeds of the first and second feeders includes controlling speeds of the first and second motors.   
     
     
         13 . The method of  claim 12 , wherein the first motor is a hydraulic motor and the second motor is a hydraulic motor. 
     
     
         14 . The method of  claim 13 , wherein the first motor is controlled by first hydrostatic pump and the second motor is controlled by a second hydrostatic pump and controlling speeds of the first and second motors includes controlling speeds of the first and second hydrostatic pumps. 
     
     
         15 . The method of  claim 11 , wherein controlling speeds of the first and second feeders includes one of substantially simultaneously increasing and decreasing speeds of the first and second feeders. 
     
     
         16 . The method of  claim 11 , further comprising:
 moving the asphalt with a third feeder, wherein the controller is further configured to control a speed of the third feeder in response to the input from the operator.   
     
     
         17 . The system of  claim 11 , further comprising:
 moving the asphalt via a third feeder to the second feeder, wherein the third feeder is controlled independently of the first and second feeders.   
     
     
         18 . The method of  claim 11 , further comprising:
 controlling speeds of the first and second feeders based on at least one of a first load sensed by a sensor configured to measure a load associated with the first feeder and a second load sensor configured to measure a load associated with the second feeder.   
     
     
         19 . The method of  claim 11 , wherein the first feeder includes a first motor and the second feeder includes a second motor and the first load is a first pressure and the second load is a second pressure. 
     
     
         20 . The system of  claim 19 , wherein the first and second motors are hydraulic motors.
