Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a material application device for building construction. Background Technology

[0002] Construction material mixing equipment is mainly used to mix various building materials, especially concrete. It is an indispensable piece of equipment in construction projects, used to mix concrete with various mix proportions to meet the needs of different construction parts and processes. In precast component plants, concrete mixers are used to produce various precast components, such as precast beams and precast slabs. In road and bridge construction, concrete mixers are used to mix the concrete materials required for road base and surface layers.

[0003] In existing concrete mixers, the mixed concrete flows out through a discharge pipe. One end of the discharge pipe is horizontal. When the concrete flows through the horizontal section of the discharge pipe, the flowability of the concrete slows down significantly due to gravity, resulting in increased residence time and a higher risk of blockage. Within the horizontal section, the pressure generated by the flowing concrete is uneven, easily leading to localized excessively high or low pressure. This causes the concrete to accumulate or clump within the pipe, further exacerbating the blockage problem. Furthermore, the particles in the concrete redistribute due to gravity within the horizontal section, resulting in uneven particle distribution. This uneven particle distribution affects the flowability and discharge speed of the concrete, increasing the likelihood of blockage. Blockage can prevent the mixer from operating continuously, requiring shutdown for cleaning. Utility Model Content

Concrete enters the discharge pipe 2 through the discharge port 8. The spiral blade 17 rotates continuously to transport the concrete inside the discharge pipe 2, preventing concrete from clogging in the discharge pipe 2.

The spiral blade 17 has high conveying efficiency and can quickly discharge concrete from the discharge pipe 2, reducing the residence time of concrete in the discharge pipe 2, thereby reducing the risk of clogging.

[0022] The transmission assembly includes a rotating column 13 and a gear ring 12. The rotating column 13 is movably installed inside the construction mixer 1, and the gear ring 12 is installed on the outer surface of the rotating column 13. The outer surface of the rotating column 13 meshes with the outer surfaces of several toothed blocks 11. A driving helical gear 15 is installed on one end surface of the rotating column 13, and a driven helical gear 16 is installed on one end surface of the driven column 14. The outer surfaces of the driving helical gear 15 and the driven helical gear 16 mesh with each other. The blocking assembly includes a telescopic cavity 18 and a pull rod 19.

Inside the construction mixer 1, a discharge baffle 20 is installed on one end of the pull rod 19. The outer surface of the discharge baffle 20 is in contact with the inner wall of the telescopic cavity 18. The double-ring stirring rod 6 and the arc-shaped stirring rod 7 stir synchronously, quickly mixing raw materials such as limestone, quartz sand, water and fly ash, ensuring that the raw materials are stirred evenly in all directions during the stirring process, thus improving the stirring efficiency. The shape and arrangement of the double-ring stirring rod 6 and the arc-shaped stirring rod 7 increase the contact area between the raw materials during the stirring process, making the stirring more uniform.

[0023] The working principle and usage process of this utility model are as follows: When it is necessary to mix the construction raw materials, limestone, quartz sand, water and fly ash are added through the feed pipe 3.

The column then drives the spiral blades 17 to rotate. When the mixing is complete, the pull rod 19 is pulled to drive the discharge baffle 20 in the telescopic cavity 1. The spiral blade 17 moves within the discharge port 8, thereby connecting the discharge port 8 with the discharge pipe 2. Concrete enters the discharge pipe 2 through the discharge port 8. The spiral blade 17 rotates continuously to transport the concrete out of the discharge pipe 2, preventing concrete from clogging inside the discharge pipe 2. The rotation of the spiral blade 17 enables continuous material transport, avoiding the clogging problems that may occur in the flow discharge method. The spiral blade 17 has high transport efficiency and can quickly discharge concrete from the discharge pipe 2, reducing the residence time of concrete in the discharge pipe 2, thereby reducing the risk of clogging.
