JZC250 concrete mixer is composed of feeding mechanism, mixing mechanism, transmission mechanism, water supply mechanism, chassis and electronic control system. The feeding mechanism is composed of a feeding frame, a feed hopper and a lifting device. Feeding mechanism of JZC250 type machine. Lifting or lowering hand lever control of feed hopper. The feed hopper is driven by the output shaft of the gear box through the shaft end of the feed clutch and the wire rope reel. The upper limit position of the hopper is controlled by a limiting device, and when the hopper is in place, the clutch is automatically disengaged, and the hopper is dropped by the deadweight of the hopper. The mixing mechanism of mixing mechanism of JZC250 mixer is the working part of the mixer, which is composed of a mixing drum, a supporting wheel and a transmission system.
The utility model is characterized in that the structure of the mixing drum is simplified, and the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is provided with a high and a low blades. The mixer rotates along with the mixing cylinder, the blade causes the material in the promotion, falls, simultaneously makes the axial reciprocating agitation, therefore stirs strongly, the effect is better. The mixing time of JZC250 concrete is about 35S-45S. The inner part of the discharge cone of the shaking cylinder is welded with a pair of discharging blades. When the concrete is mixed, the rotating direction of the mixing cylinder is changed. The mixing drum is composed of four roller bearing, the mixing drum rotation is driven by the gear installed in the simplified circle and realized by a motor through a transmission system, reliable work, reversing drum is achieved by reversing the motor.
The water supply system is composed of an electric motor, a water pump, a regulating valve, a suction valve and a pipeline. Start the pump, then the water can be injected into the mixing drum, stirring every tank concrete water required by the time relay in control system to control pump operation time to master, when the button is rotated to "control" position, the pump will operate according to the set time and automatically stop. When the button is rotated to the "manual" position, the water can be continuously supplied.
