Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a building steel cage concrete grouting device. Background Art

[0002] Precast concrete parts refer to concrete products that are processed and produced in a standardized and mechanized manner in a factory. In contrast, traditional cast-in-place concrete requires on-site mold making, on-site pouring and on-site maintenance. Precast concrete parts are widely used in construction, transportation, water conservancy and other fields. During the processing of precast concrete parts, it is necessary to first make a steel cage, then place the steel cage in the mold, pre-tighten it, and then grout it. In addition, during the assembly process of the precast parts, concrete slurry needs to be poured between the two precast parts through a grouting device.

[0003] The existing grouting device needs to stir the concrete first when in use, and then transport it to the junction of the two prefabricated parts through the action of the dragon and the pipeline. Although the existing grouting device usually has a mixer, the multiple stirring blades on the stirring shaft of the existing mixer are usually fixed, which leads to the concrete between the upper and lower stirring blades not being fully stirred, and the concrete blades between the lowest stirring blade and the bottom of the mixing barrel are difficult to be stirred, which makes the viscosity between the concrete poor, affecting the stability between the prefabricated parts. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a construction steel cage concrete grouting device, which can drive a plurality of stirring blades to rotate with a stirring shaft driven by a motor, and at the same time, can enable a rolling component to transport the concrete between two upper and lower adjacent stirring blades at corresponding positions from bottom to top, so that the concrete between the plurality of stirring blades can be fully stirred, and the time of concrete stirring can be reduced, thereby improving the efficiency of concrete mixing.

The rotating bevel gear three 22227 can make the auger 22225 at the corresponding position rotate. Since the two adjacent double-groove pulleys 22226 are connected by belt transmission, the rotating auger 22225 can make the plurality of augers 22225 at the corresponding position rotate. 2225 rotates simultaneously, and the multiple rotating augers 22225 can transport the concrete between the two adjacent stirring blades 2212 at the corresponding positions from bottom to top, so that the concrete between the multiple stirring blades 2212 can be fully stirred, and the time of concrete stirring can be reduced, and the efficiency of concrete stirring can be improved. At the same time, the two electric push rods 22113 are started, and the output ends of the electric push rods 22113 are reciprocated to make the stirring shaft 2211 and the multiple stirring blades 2212 reciprocate. Since the bottom surface of the mixing barrel 21 is a conical structure, when the stirring shaft 2211 moves downward, the pressing block 2215 can move the accumulated The concrete at the bottom of the mixing barrel 21 is squeezed, causing the concrete accumulated at the bottom of the mixing barrel 21 to spread out to the periphery (similar to stepping on water with your feet, water will spread out to the periphery). Since the end of the stirring blade 2212 is in close contact with the airbag 212 and the side where the airbag 212 and the stirring blade 2212 are in contact are concave, the rotating stirring blade 2212 can cause the airbag 212 to push the concrete that the stirring blade 2212 cannot touch to the middle of the mixing barrel 21. When the concrete mixing is completed, the mixed concrete is poured into the conveying mechanism 3 through the discharge port at the bottom of the mixing barrel 21, and then the concrete is poured into the connection between the two prefabricated parts through the conveying mechanism 3.
