Abstract
An electro-hydraulic actuation system for a sprayer comprises a hydraulic system, a hydraulic actuator, an electric actuator and a sprayer. The hydraulic system is for pressurizing a hydraulic fluid. The hydraulic actuator is powered by the hydraulic system. The electric actuator controls actuation of the hydraulic actuator by the hydraulic system. The sprayer is actuated by the hydraulic actuator.
Claims20
A line striping system comprising:
- a chassis;
- a wheel mounted to the chassis;
- a spray system mounted on the chassis, the spray system comprising:
- a spray gun having a lever;
- and
- a fluid pump that provides pressurized fluid to the spray gun;
- an electrically controlled actuation system connected to the spray system, the electrically controlled actuation system comprising:
- an actuator;
- and
- a cable connected between the actuator and the lever of the spray gun, so that activation of the actuator causes the cable to actuate the spray gun.
7 more elements
A line striping system comprising:
- a spray system comprising:
- a first spray gun having a lever;
- a fluid pump that provides pressurized fluid to the first spray gun;
- an electrically controlled actuation system connected to the spray system, the electrically controlled actuation system comprising:
- a first actuator;
- and
- a first cable that is connected between the first actuator and the first spray gun, so that activation of the first actuator causes the first cable to actuate the lever of the first spray gun.
4 more elements
A line striping system comprising:
- a chassis;
- a plurality of wheels mounted to the chassis to allow the chassis to roll;
- a handlebar;
- a spray system supported by the chassis, the spray system comprising:
- one or more lever actuated spray guns positioned for painting stripes on the ground by spraying;
- and
- a fluid pump that provides paint under pressure to the one or more lever actuated spray guns;
- an electrically controlled actuation system supported by on the chassis, the actuation system comprising:
- an actuator mounted on the chassis, the actuator comprising one or more electric solenoids;
- a push-button control mounted on the handlebar;
- and
- one or more cables that extends from the actuator and are linked to the one or more lever actuated spray guns, wherein actuation of the push-button control causes activation of the one or more solenoids and the one or more cables to be pulled by the electrically controlled actuation system sufficient to actuate the one or more lever actuated spray guns to spray one or more stripes on the ground.
