The invention of an automatic feeding mixer is used to solve the problem that the mixer in the prior art has a single function and can only carry out the task of concrete conveying. The automatic feeding mixer includes a mixing body, on which a mixing tank is installed. The mixing tank can rotate freely for 290 degrees. The mixing tank is driven and rotated by the hydraulic mechanism of the mixing body. The mixing tank is tilted. The upper end of the mixing tank is opened, and the opening is provided with a feeding port fixed on the mixing body. The mixing screw is installed in the mixing tank. The two sides of the mixing tank are symmetrically equipped with a boom, and one end of the boom is hinged on the mixing body, The mixing machine body is also provided with a lifting cylinder for driving the boom to rise and fall; A hopper is fixed between the two booms, one end of the hopper close to the feeding port is provided with a bin door, and the hopper is provided with a discharge cylinder for controlling the opening and closing of the bin door. The automatic feeding mixer is simple in structure and easy to use. It can realize the mixing, feeding and discharging of concrete without too many operators. It has good practicability.

自动上料搅拌机适应小型工程建设集自动上料、搅拌、运输、自动卸料于一体的混凝土搅拌运输机。采用大功率柴油发动机，液力变矩器，保证行走与搅拌同时工作所需动力。

The automatic loading mixer is suitable for the construction of a concrete mixing conveyor integrating automatic loading, mixing, transportation and automatic unloading in small projects. High power diesel engine and hydraulic torque converter are used to ensure the power required for walking and mixing at the same time.

自动上料搅拌机主要结构由：行走底盘、发动机、液力变矩器、前后双驱桥、上料装置、进料斗、卸料斗、加长卸料斗、机架、搅拌筒、搅拌推荐减速机、液压系统、电控系统、自动上水系统等组成，其特征如下：

The main structure of the automatic feeding mixer is composed of: traveling chassis, engine, hydraulic torque converter, front and rear double drive bridges, feeding device, feed hopper, discharge hopper, extended discharge hopper, frame, mixing drum, mixing recommended reducer, hydraulic system, electric control system, automatic water feeding system, etc. Its characteristics are as follows:

1.行走系统由发动机通过液力变矩器、前后传动轴到前后桥。本发明采用前后双桥驱动形式。采用液力变矩器减少对发动机的冲击、延长了发动机的寿命。

1. the traveling system is from the engine to the front and rear axles through the hydraulic torque converter and the front and rear transmission shafts. The invention adopts a front and rear double axle driving form. The hydraulic torque converter is used to reduce the impact on the engine and prolong the service life of the engine.

2.液压系统采用恒功率变量柱塞泵，减少发动机的功率损耗，。

2. the hydraulic system adopts constant power variable piston pump to reduce the power loss of the engine,.

3. 搅拌筒的旋转由液压马达通过推荐行星减速机带动，行星减速机的输出轴可以实现一定角度的摆动，以满足恶劣路况下搅拌筒的跳动。

3. the rotation of the mixing drum is driven by the hydraulic motor through the recommended 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. 干料上料，按照设计好的配比由铲臂、动臂缸、定量的料斗自动上料。

4. dry materials shall be loaded automatically by shovel arm, boom cylinder and quantitative hopper according to the designed ratio.

5.进水系统可根据计量设定实现自动进水。

5. the water inlet system can realize automatic water inlet according to the metering setting.

6.搅拌筒内壁上设置双螺旋形叶片，正向旋转为进料、混凝土搅拌；反向旋转，在螺旋叶片的推动下、混凝土由出料口出料。

6. double spiral blades are set on the inner wall of the mixing drum, and the positive rotation is feeding and concrete mixing; Reverse rotation, the concrete is discharged from the discharge port under the push of the spiral blade.
