A stall protection device for concrete mixing equipment

Abstract

A stall protection device for concrete mixing equipment, relating to the technical field of concrete, a stall protection device for concrete mixing equipment, comprising a housing, the bottom of the housing is fixedly connected with a fixing seat, and a ring is provided in the middle of the fixing seat, The inner wall of the ring is movably connected with evenly distributed turning blocks, the inner wall of the turning block is fixedly connected with an electromagnet, the inner wall of the turning block is provided with a damping hole, the inner side of the turning block is fixedly connected with a stirring rod passing through the fixed seat, and the inner wall of the stirring rod There are two mutually symmetrical chutes. The stall protection device for concrete mixing equipment is used in conjunction with the electromagnet and the rotary block. When the stirring device rotates too fast, the electromagnet is in the energized state at this time, and the viscosity of the magnetorheological fluid in the ring increases. At this time, the magnetorheological fluid in the damping hole is difficult to flow, which effectively reduces the rotation speed of the rotary block, further reduces the rotation speed of the stirring rod, ensures the stable stirring of the stirring device, and improves the uniform mixing degree of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a stall protection device for concrete mixing equipment. Background technique [0002] Concrete is a kind of building material often used in construction. Concrete is mainly used to improve the strength of the building, ensure the stability of the building, and effectively improve the safety and quality of the building. Most of the current concrete is produced by machinery, and the raw materials are added to the mixing equipment. In the mixing process, it is stirred to fully mix the raw materials, but the current mixing device often has some problems when it is used, resulting in uneven mixing and affecting the quality of the concrete. [0003] When the current stirring device is in use, most of the stirring rods are driven by the motor to rotate, but when the current motors are rotating, stalls often occur, causing the stirring rod to rotate too fast, stirring the raw materials...

Problems solved by technology

[0002] Concrete is a building material often used in construction. Concrete is mainly used to improve the strength of the building, ensure the stability of the building, and effectively improve the safety and quality of the building. At present, most of the concrete is produced by machinery, and the raw materials are added to the mixing equipment. In the process, it is stirred to fully mix the raw materials, but the current mixing device often has some problems when it is used, resulting in uneven mixing and affecting the quality of concrete.

[0003] When the current stirring device is in use, most of the stirring rods are driven by the motor to rotate. However, when the current motors are rotating, stalls often occur, causing the stirring rods to rotate too fast, stirring the raw materials to the outside of the mixing tank, making it difficult for the raw materials to Insufficient mixing, resulting in uneven mixing of the final concrete, which greatly reduces the quality of the concrete
