Abstract
A concrete mixer system includes a washout system and a controller. The washout system includes a tank configured to store a fluid, a plurality of electronically controllable valves in fluid communication with the tank, and a plurality of nozzles. One or more of the plurality of nozzles are fluidly coupled to a respective one of the plurality of electronically controllable valves. Each of the plurality of nozzles is configured to be positioned to facilitate washing a respective component of a concrete mixer vehicle. The controller is configured to (i) receive an indication that the washout system is coupled to a continuous fluid source and (ii) operate the washout system in a continuous wash mode in response to receiving the indication.
Claims18
A concrete mixer system comprising:
- a washout system including:
- a tank configured to store a fluid;
- an electronically controllable valve;
- and
- a nozzle configured to be positioned proximate a charge hopper of a concrete mixer vehicle;
- and
- a controller having one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
- receive an indication that a mixing drum of the concrete mixer vehicle is about to be charged;
- and
- control the electronically controllable valve in response to the indication such that the fluid is provided to the nozzle from the tank to facilitate pre-wetting the charge hopper of the concrete mixer vehicle prior to the mixing drum being charged.
A concrete mixer system comprising:
- a washout system including:
- a tank configured to store a fluid;
- a plurality of electronically controllable valves in fluid communication with the tank;
- and
- a plurality of nozzles, one or more of the plurality of nozzles fluidly coupled to a respective one of the plurality of electronically controllable valves, each of the plurality of nozzles configured to be positioned to facilitate washing at least one of a charge hopper, a mixing drum, a discharge hopper, or chute of a concrete mixer vehicle with the fluid;
- and
- a controller having one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to operate the washout system in a no mess mode based on a location of the concrete mixer vehicle to prevent one or more of the plurality of electronically controllable valves from being activated to prevent washing at least the discharge hopper and the chute to prevent the fluid from being discharged onto the ground at the location.
A concrete mixer system comprising:
- a washout system including:
- a tank configured to store a fluid;
- an electronically controllable valve;
- and
- a nozzle configured to be positioned proximate a discharge hopper or a chute of a concrete mixer vehicle;
- and
- a controller having one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
- receive an indication that a mixing drum of the concrete mixer vehicle is about to be discharged;
- and
- control the electronically controllable valve in response to the indication such that the fluid is provided to the nozzle from the tank to facilitate pre-wetting the discharge hopper or the chute of the concrete mixer vehicle prior to the mixing drum being discharged.
