Shanqi full-automatic mixer is used to solve the problem that the mixer has a single function and can only carry out the task of concrete transportation in the prior art. The mixing car comprises a mixing car body, a mixing tank is installed on the mixing car body, the mixing tank is driven and rotated by the hydraulic mechanism of the mixing car body, the mixing tank is arranged obliquely, the high end of the mixing tank is opened, the opening is provided with a feeding port fixed on the mixing car body, the mixing screw is installed in the mixing tank, and the boom is symmetrically arranged on both sides of the mixing tank, One end of the boom is hinged on the mixing car body, and the mixing car body is also provided with a lifting oil cylinder for driving the boom to rise and fall; A hopper is fixed between the two booms, a bin door is arranged at one end of the hopper close to the feeding port, and a discharge oil cylinder for controlling the opening and closing of the bin door is arranged on the hopper. The fully automatic feeding mixer has the advantages of simple structure and simple use. It can realize the mixing, feeding and discharging of concrete without too many staff operation, and has good practicability.
The main structure of the full-automatic mixer is composed of: walking chassis, engine, hydraulic torque converter, front and rear double drive bridges, feeding device, feed hopper, discharge hopper, extended discharge hopper, frame, mixing drum, special mixing reducer, hydraulic system, electric control system, automatic water feeding system, etc. Its Characteristics are as follows:
1. The traveling system is from the engine to the front and rear axles through the hydraulic torque converter and front and rear transmission shafts. The invention adopts the form of front and rear double axle drive. The hydraulic torque converter is used to reduce the impact on the engine and prolong the service life of the engine.
2. The hydraulic system adopts constant power variable piston pump to reduce the power loss of the engine,.
3. The rotation of the mixing drum is driven by the hydraulic motor through the special planetary reducer. The output shaft of the planetary reducer can swing at a certain angle to meet the beating of the mixing drum under bad road conditions.
4. Dry materials shall be loaded automatically by shovel arm, boom cylinder and quantitative hopper according to the designed ratio.
5. The water inlet system can realize automatic water inlet according to the metering setting.
6. Double spiral blades are set on the inner wall of the mixing drum, which rotate forward for feeding and concrete mixing; The concrete is discharged from the discharge port under the push of the spiral blade.
