Intelligent concrete mixer

Abstract

The invention discloses an intelligent concrete mixer which comprises a cementing material storage box, an aggregate storage box, a water storage box, a cementing material preloading box which is provided with a first weight sensor, an aggregate preloading box which is provided with a second weight sensor, a water preloading box which is provided with a third weight sensor, and a mixing box; the communication between the cementing material preloading box and the cementing material storage box, the communication between the cementing material preloading box and the mixing box, the communicationbetween the aggregate preloading box and the aggregate storage box, the communication between the aggregate preloading box and the mixing box, the communication between the water preloading box and the water storage box, and the communication between the water preloading box and the mixing box are controlled through electromagnetic valves; and a master control module is electrically connected with the various weight sensors and the various electromagnetic valves so as to control operation of the various electromagnetic valves according to proportions of three materials. By means of the design, the proportions of the three materials are controlled precisely and automatically, staff simply need to set data as required, the operation is simple, and the quality of concrete is ensured.

Description

technical field [0001] The invention relates to the field of concrete processing, in particular to an intelligent concrete mixer. Background technique [0002] Traditional concrete mixers add the amount of cementitious material, aggregate, and water through human judgment. After the coagulation is completed, it is necessary to manually observe the concrete to adjust the ratio of cementitious material, aggregate, and water. It requires rich experience to debug a better coagulation ratio, which is impossible for novices to operate, and improper coagulation ratio will also affect the quality of the project. [0003] Later, a manufacturer created an intelligent mixer, which has a cementitious material storage tank, an aggregate storage tank, a water storage tank and a mixing tank. At the same time, three solenoid valves are used to control the conduction between the mixing tank and the other three storage tanks. , the controller regularly controls the on and off of the solenoid...

[0002] Traditional concrete mixers add the amount of cementitious material, aggregate, and water through human judgment. After the coagulation is completed, it is necessary to manually observe the concrete to adjust the ratio of cementitious material, aggregate, and water. It requires rich experience to debug a better coagulation ratio, which is impossible for novices to operate, and improper coagulation ratio will also affect the quality of the project

[0003] Later, a manufacturer created an intelligent mixer, which has a cementitious material storage tank, an aggregate storage tank, a water storage tank and a mixing tank. At the same time, three solenoid valves are used to control the conduction between the mixing tank and the other three storage tanks. , the controller regularly controls the on and off of the solenoid valve, thereby controlling the ratio of the cementitious material, aggregate, and water. However, the cementitious material and aggregate are solid, and the water is liquid. The flow rates of the three are obviously different. At the same time, the different storage conditions in the storage tank, the blockage of the pipeline and other special circumstances may cause the amount of each outflow to be inconsistent, and it is difficult to accurately control the amount of each outflow, resulting in a large deviation in the proportion of the final concrete.
