Direct charge concrete mixer

A batch plant, comprising:

• a frame;
• a cement supply;
• an aggregate supply;
• a mixture delivery system comprising:
• a mixture output mechanism having an inlet and an outlet, wherein the outlet is selectively repositionable relative to the frame;
• and
• a controller configured to:
• determine a state of a mixing drum proximate the outlet of the mixture output mechanism;
• determine a state of the mixture output mechanism;
• and
• based on the state of the mixing drum and the mixture delivery system:
• (i) obtain a setpoint value for an actuator of the mixture delivery system, the setpoint value associated with a position of the mixture output mechanism such that the outlet is disposed within a volume of the mixing drum, (ii) apply the setpoint value to the actuator of the mixture delivery system, and (iii) activate the mixture delivery system to dispense material directly into the volume.

A concrete mixer vehicle, comprising:

• a chassis;
• a mixing drum assembly coupled to the chassis, the mixing drum assembly comprising:
• a mixing drum defining an aperture configured to receive a material and a volume configured to contain the material;
• a mixing element positioned within the volume and coupled to the mixing drum;
• a pedestal coupled to the chassis and configured to support the mixing drum, the pedestal defining a mount for removably attaching an accessory to the pedestal;
• a collector positioned to receive material from the mixing drum;
• and
• a chute positioned to receive the material from the collector;
• an auxiliary fluid system comprising:
• an admixture system configured to selectively add an admixture material to the mixing drum;
• and
• a washout system configured to wash at least one of an interior of the mixing drum, an exterior surface of the mixing drum, the collector, or the chute;
• a user access point coupled to the chassis;
• and
• a controller configured to:
• obtain a setpoint value for an actuator of the concrete mixer vehicle, the setpoint value associated with a position of the actuator such that an outlet of a mixture delivery system of a batch plant is disposed within the volume,
• apply the setpoint value to the actuator of the concrete mixer vehicle, and
• activate the mixture delivery system of the batch plant to output material directly into the volume of the mixing drum to thereby directly charge the concrete mixer vehicle with material.
