Therefore, accurately controlling the proportional relationship between materials and water is crucial for ensuring the project quality. During the proportioning process, a special proportioning device is usually required.

[0003] Traditional proportioning devices are usually equipped with a feeding structure to add various materials and water into the batching kettle. However, for the control of the proportion between materials and water, such devices often rely on the experience and judgment of the operator rather than precise automatic control. This approach has the following problems:

A plurality of observation windows 17 for observing the mixing situation of the material are evenly arranged on the outer side wall of the batching kettle 2. The observation windows 17 are made of wear-resistant materials and are not easily damaged by the friction of the material inside the batching kettle 2. A proportioning assembly is provided on the support 1, and a stirring assembly is provided on the kettle lid 3.

[0026] As shown Figures 1-3 in the figure, the proportioning component includes a storage hopper 4, a motor I 5, a screw conveyor rod 6 and a blanking pipe 7. The left and right sides of the top of the bracket 1 are symmetrically connected with a storage hopper 4 for placing materials. Motors I 5 are installed on the outer sides of the storage hoppers 4. The motors I 5 are electrically connected to the integrated controller 18. Inside the storage hoppers 4, screw conveyor rods 6 for pushing materials are rotatably connected. The output shafts of the motors I 5 are connected to the screw conveyor rods 6 on the same side. Blanking pipes 7 are welded on the inner sides of the storage hoppers 4.

The motor II 10 is installed on the top of the kettle cover 3 through bolts. The motor II 10 is electrically connected to the integrated controller 18. The output shaft of the motor II 10 penetrates into the kettle cover 3. A rotating frame 101 is connected to the output shaft of the motor II 10. Four connecting rods 11 are evenly rotatably connected along the circumference on the outer side of the rotating frame 101. Stirring paddles 12 for mixing materials are connected to the connecting rods 11. The rotating frame 101, the connecting rod 11 and the stirring paddle 12 are all located inside the batching kettle 2. A rotating disk 14 is rotatably connected to the bottom of the kettle cover 3.

[0028] When mixing and proportioning building materials, different categories of building materials are added into the two storage hoppers 4, the water tank 8 is filled with clear water, and then the power supply of the device is started. The integrated controller 18 is operated to start the motor I 5. The output shaft of the motor I 5 rotates to drive the screw conveyor rod 6. The screw conveyor rod 6 pushes the materials inward to the blanking pipe 7. The materials fall into the batching kettle 2 through the blanking pipe 7 and the feeding port 33. At this time, the motor II 10 and the solenoid valve I 91 are started, so that the clear water in the water tank 8 slowly flows into the batching kettle 2 through the water inlet pipe 9. After the motor II 10 is started, the output shaft rotates to drive the rotating frame 101, the connecting rod 11 and the stirring paddle 12 to rotate. The connecting rod 11 drives the gear 13 and the rotating disk 14 to rotate. The gear 13 meshes with the gear ring 31. Under the action of the gear ring 31, the gear 13 rotates self. The gear 13 drives the connecting rod 11 and the stirring paddle 12 to rotate self, so that the stirring paddle 12 rotates self while rotating with the rotating frame 101, fully mixes the materials in the batching kettle 2, and mixes them with the clear water. The radio frequency sensor 16 works by emitting electromagnetic waves and receiving the signals reflected from the surface or inside of the materials. Materials with different humidities will affect these electromagnetic waves in different ways, so the humidity level can be deduced by analyzing the changes in the reflected signals. Furthermore, the opening and closing of the solenoid valve I 91 are controlled through the integrated controller 18 to control the amount of water flowing out. After the humidity is appropriate, the solenoid valve I 91 is closed to stop the outflow of clear water. The mixing condition of the materials can be known by checking the observation window 17. After the material proportioning is completed, the solenoid valve II 151 can be opened by operating the integrated controller 18. The mixed materials will be discharged through the discharge pipe 15. The stirring paddle 12 can continue to rotate to assist the rapid discharge and collection of the materials. After use, the power supply of the device can be turned off.
