Background
The action principle of the cement stabilized macadam is as follows: the cement stabilized macadam takes graded macadam as aggregate, adopts a certain amount of cementing materials and enough mortar volume to fill the gap of the aggregate, and is paved and compacted according to the embedding and extruding principle. The compactness of the mortar is close to the compactness, the strength mainly depends on the embedding, extruding and locking principles among the gravels, and simultaneously, the mortar has enough volume to fill the gaps of the aggregate. Its initial strength is high, and its strength can be quickly increased with age, and can be quickly formed into plate body, so that it has high strength, and good impermeability and frost resistance.
In the mixing process of the cement stabilized macadam, the uniformity of mixture mixing is a key link influencing the quality of the cement stabilized macadam base course. At present, a general cement stabilized macadam mixing station adopts a belt conveyor to convey mixed materials to a finished product bin. After the mixture is thrown out, the materials with larger particle size have large kinetic energy, and after the mixture falls down, the horizontal displacement is larger than that of the materials with smaller particle size, so that the separation of large materials and small materials in a finished product bin is caused, and the phenomenon of serious throwing segregation occurs. The produced segregated finished material is still in a segregated state after being discharged to a transport vehicle, so that the original design gradation is changed, a series of diseases of the road surface are caused, and the service life of the roadbed and the road surface is seriously shortened.
CN104894947B discloses a steady mixing station of water prevents segregation device, is located between mixture conveyer's discharge end and the play feed bin, including keeping off the anti-segregation baffle in mixture conveyer's the discharge end outside and vertical setting, prevent that the segregation baffle blocks the stone of departure, prevents that big stone from separating from the mixture. The segregation preventing device has the following defects: the back is blockked the rubble to the baffle of preventing educing, and the comparatively concentrated whereabouts of rubble can be piled up under the baffle of preventing educing, influences the space utilization who goes out the feed bin.
Disclosure of Invention
The invention aims to solve the defects of the prior art, and provides an anti-segregation device for a cement stabilized macadam mixing station.
The technical problem to be solved by the invention is realized by adopting the following technical scheme: an anti-segregation device of a cement stabilized macadam mixing station comprises a support, an anti-segregation roller, a torque sensor, a controller and a braking device; the anti-segregation roller comprises a rotating shaft, end plates and material guide rods, the anti-segregation roller is horizontally arranged on the support through the rotating shaft, the end plates are arranged on two sides of the anti-segregation roller, the material guide rods are fixedly arranged between the two end plates, and the material guide rods are provided with a plurality of material guide rods and are uniformly distributed at intervals along the same circumference with the rotating shaft as the center of a circle; torque sensor and arresting gear all install on the support, torque sensor is used for detecting and prevents the moment of torsion of segregation roller to the controller feedback, the controller is used for handling the moment of torsion of preventing segregation roller and control arresting gear to preventing segregation roller braking, arresting gear's braking force is positive correlation with the moment of torsion that torque sensor detected.

Through horizontal straight line module, can adjust the horizontal position of preventing the roller of educing to adjust the mixture and act on the position of preventing the roller of educing, in order to realize preventing the corotation or the reversal of educing the roller, what make the mixture disperse more falls into the feed bin.
The technical scheme of the invention is as follows: the braking device is an electromagnetic brake, and two ends of the rotating shaft are respectively connected with the input port of the torque sensor and the input port of the electromagnetic brake.
The technical scheme of the invention is as follows: the radial section of the material guide rod is circular.
After the mixture is thrown out by the belt conveyor, the mixture acts on the anti-segregation rollers, the kinetic energy of the mixture is converted into the rotational kinetic energy of the anti-segregation rollers, the anti-segregation rollers are made to rotate, a part of the mixture passes through the space between the material guide rods and enters the interior of the anti-segregation rollers, the mixture is thrown out in a dispersed manner along with the rotation of the anti-segregation rollers, the other part of the mixture is rebounded to the opposite direction by the rotating anti-segregation rollers, if the torque sensor detects that the torque of the anti-segregation rollers is too large, the controller controls the electromagnetic brake to increase the braking force, otherwise, the braking force is reduced, and therefore the segregation phenomenon is further prevented, therefore, compared with the prior art, the anti-segregation device for the cement stabilized macadam mixing station has the beneficial effects that: (1) the kinetic energy of the mixture can be reduced to prevent the mixture from segregation; (2) the rotating anti-segregation roller can further stir the mixture to further uniformly mix the mixture; (3) the rotating anti-segregation roller scatters or rebounds the mixture, so that the mixture is prevented from being accumulated in the discharging bin in a concentrated manner, and the space utilization rate of the discharging bin is improved; (4) if the crushed stone with large particle size enters the anti-segregation roller, the anti-segregation roller has larger rotation kinetic energy, and if the crushed stone with large particle size is not braked, the crushed stone with large particle size is thrown too far, so that the segregation phenomenon is caused.
