Background technology
Concrete mixing and transporting car not only has the transportation function of traditional trucd mixer, and has the concrete-agitating function.Therefore, the requirement to rotating speed and time is just higher in the process of ready-mixed concrete.Common trucd mixer can't have one to measure intuitively to rotating speed, and mixing speed can only by virtue of experience observe to judge the time transfer speed of stirring with mixing time with vision, causes that quality is difficult to be guaranteed in the trucd mixer mixed concrete.
Summary of the invention
Electric-control system for concrete mixing and transporting car of the present invention efficiently solves the problem that mixing speed and mixing time can only artificial judgment.
For addressing the above problem, the present invention is by the following technical solutions: the electric-control system that is used for concrete mixing and transporting car, it is characterized in that, comprise hydraulic power unit, single-chip microcomputer, touch-screen, tachogenerator, the first power supply, second source and hydraulic actuator, described single-chip microcomputer is connected with touch-screen, magnetic valve and tachogenerator respectively, described hydraulic power unit comprises dc motor, magnetic valve and hydraulic pump, described dc motor is connected with hydraulic pump with magnetic valve and is connected, and hydraulic pump links to each other with hydraulic actuator; Described the first power supply provides operating voltage for single-chip microcomputer and touch-screen, and described second source provides operating voltage for dc motor.
Further, also comprise buzzer, described buzzer is connected with single-chip microcomputer.
Preferably, the voltage and current of described the first power supply supply is respectively: 24V, 0.2A; The voltage and current of described second source supply is respectively: 24V, 10A ~ 62.5A.
Preferably, described single-chip microcomputer model is the CUP222 in the Siemens S7-200 series.
Preferably, described hydraulic actuator is two oil cylinders, and described two oil cylinders are installed in respectively the place that hoists of feed hopper seal cover and discharging chute.
