Description

Technical Field

[0001] The utility model relates to the field of cement pole manufacturing, in particular to an automatic weighing and stirring device for cement poles. Background Art

[0002] Cement poles are mainly made of a mixture of cement, fine sand and gravel, supplemented with steel bars to enhance strength, so they are also called reinforced concrete cement poles. They are mainly used as wire support pillars in the power, communications, railways, petroleum and other industries.

[0003] When cement poles are manufactured, the raw materials need to be weighed before mixing. Currently, cement pole mixing devices on the market do not have a weighing structure and most rely on manual weighing, which not only increases labor intensity, but also makes it difficult to ensure uniform quality of the poles due to human operating errors.

The PLC controller controls the feed solenoid valve to close and controls the dumping motor to rotate, driving the weighing tank to pour the material into the mixing barrel. The weighing tank then returns to its original position and repeats the above steps until the total weight of the material reaches the set value.

[0009] Furthermore, the combination of the weighing tank and the dumping motor can be provided as one set to weigh the materials one by one in sequence; or multiple sets can be provided to weigh various materials separately and simultaneously.
