Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing and pouring equipment, in particular to a device for preventing concrete from vibrating and segregating. Background Art

[0002] When the height of the concrete column is high, due to the different weights of gravel, sand and cement slurry, during the pouring process, due to the buoyancy of cement slurry, the gravel falls relatively fast, while the sand falls relatively slowly, which easily leads to the separation of gravel and sand. This phenomenon is especially serious when the height of the concrete column exceeds 3m. Therefore, how to provide a device to prevent concrete segregation is an urgent problem to be solved by technicians in this field. In addition, since concrete materials are piled together for concentrated discharge, it is easy to make the discharge rate difficult to control, which has certain disadvantages. To this end, we propose a device to prevent concrete segregation by vibration. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2The utility model provides a technical solution: a device for preventing concrete from vibrating and segregating, comprising a mixing drum 1 installed on a support seat 11, a feed port at the top of the mixing drum 1 being connected to a hopper 15 through a feed pipe 14, a first motor 16 being arranged on the top of the mixing drum 1, a rotating shaft 17 being connected to the bottom of the first motor 16, a mounting bracket 18 being arranged on the rotating shaft 17, a plurality of stirring rods 19 being arranged on the mounting bracket 18, a cylinder body 2 being arranged on the other side of the mounting bracket 18, a feeding auger 21 being installed in the cylinder body 2, two unloading plates 24 being arranged in the lower area of ​​the mixing drum 1, a roller shaft 25 being arranged on the inner side of the unloading plate 24, and a plurality of dividing plates 26 being arranged on the side of the roller shaft 25.

[0017] In the above solution, a support column 12 is provided at the bottom of the support seat 11 .

[0018] In the above solution, a protective cover 13 is provided outside the mixing barrel 1 .

[0019] In the above scheme, the top of the feeding auger 21 is connected to a second motor 22, and the second motor 22 is installed on a connecting bracket 23. By arranging the rotating shaft 17, the mounting bracket 18, the stirring rod 19, the barrel 2, the feeding auger 21, the second motor 22, the first motor 16 and other structures inside the mixing barrel 1, the concrete material entering the mixing barrel 1 can be continuously stirred, and at the same time, the feeding auger 21 inside the barrel 2 is driven by the second motor 22 to rotate so that the material in the lower part of the mixing barrel 1 is automatically transferred upward, so that the material can be evenly moved inside the mixing barrel 1, thereby effectively improving the mixing effect of the material and ensuring the processing quality of the concrete.

[0020] In the above solution, the end of the roller shaft 25 is connected to the third motor 27. Specifically, the first motor 16, the second motor 22 and the third motor 27 are all forward and reverse motors, and are connected to a power supply and a switch through a wire.

[0021] In the above solution, the side of the mixing drum 1 is connected to the aeration mechanism through the aeration pipe 28. The aeration mechanism allows the airflow generated from the bottom inside the mixing drum 1 to impact the concrete material, so that the material can be further fully mixed.

[0022] In the above scheme, a feed pipe 29 is provided at the bottom of the mixing barrel 1, and a solenoid valve is provided on the feed pipe 29. By providing two sets of inclined feed plates 24, the concrete material can be guided, and at the same time, the feed rate can be controlled by the feed dividing mechanism composed of the roller 25 and the feed dividing plate 26 provided on the inner side thereof, so as to achieve the purpose of balanced control of the concrete feed rate and ensure the stability of the processing process. The feed dividing mechanism composed of the roller 25 and the feed dividing plate 26 is installed in the middle channel of the two feed plates 24. When the material moves down from the channel, it accumulates in the area between the two feed dividing plates 26. The third motor 27 drives the roller 25 and the feed dividing plate 26 to rotate, and transfers the material above downward. At this time, the solenoid valve on the feed pipe 29 is opened, so that the material can be discharged from the feed pipe 29.

[0023] Working principle:

[0024] When the device for preventing concrete from being vibrated and segregated is used, the concrete material enters the feeding pipe 14 from the hopper 15 and then enters the mixing barrel 1. At this time, the first motor 16 drives the rotating shaft 17 to rotate, and the material is continuously stirred and mixed through the stirring rod 19. At the same time, the feeding auger 21 inside the barrel 2 is driven to rotate under the action of the second motor 22, so that the material in the lower part of the mixing barrel 1 is automatically transferred upward, and the material can be evenly moved inside the mixing barrel 1, thereby effectively improving the mixing effect of the material. The processed concrete material moves downward into the area between the two dividing plates 26, and then the third motor 27 drives the roller 25 and the dividing plate 26 to rotate, and transfers the upper material downward. At this time, the solenoid valve on the discharge pipe 29 is opened, so that the material can be discharged from the discharge pipe 29. With the cooperation of the above-mentioned mechanism, the mixing quality of the concrete material is effectively guaranteed, and the phenomenon of segregation of materials such as gravel and sand is avoided.
