Concrete is widely used in various building structures, such as bridges, roads, dams, houses, etc., due to its good compressive strength, durability and plasticity. When using concrete, in order to quickly and continuously transport concrete to the construction site, reducing the time and labor intensity of manual handling, a conveying pipeline is usually used to transport concrete. A concrete conveying pipeline is a device specially used to transport concrete, which is usually connected by multiple sections of steel pipes or plastic pipes. Concrete can be transported continuously and quickly through a concrete conveying pipeline, so that concrete can quickly reach the construction site in a shorter time, which can speed up the progress of the project, help improve construction efficiency and shorten the construction period.

[0003] When conveying concrete through a conveying pipeline, concrete is usually pumped into the pipeline to realize the conveying of concrete through the pipeline. After entering the pipeline, concrete is easy to coagulate in the pipeline, which will lead to accumulation in the pipeline. However, in the prior art, the pipeline cannot be well dredged, so that after the concrete accumulates, it is easy to cause the pipeline to be blocked, thereby affecting the conveying efficiency.

Through the arrangement of the spiral conveying rod 25, the spiral conveying rod 25 can stably convey concrete when it rotates, which can prevent the accumulation of concrete in the conveying pipe body 1 and cause the conveying pipe body 1 to be blocked, which is beneficial to improving the efficiency and effect of transportation.

[0025] Furthermore, the anti-blocking mechanism also includes a connecting rod 27, which is fixedly connected to the surface of the spiral conveying rod 25. A scraper 28 is fixedly connected to one end of the connecting rod 27 away from the spiral conveying rod 25, and a crushing tooth 29 is fixedly connected to the inner surface of the scraper 28. Through the arrangement of the scraper 28, when the spiral conveying rod 25 rotates, the connecting rod 27 can drive the scraper 28 to rotate under the action of the spiral conveying rod 25, and then the scraper 28 can scrape the inner wall of the conveying pipe body 1, which is beneficial to reduce the adhesion and condensation of concrete on the inner wall of the conveying pipe body 1, and can ensure the smooth delivery of concrete by the conveying pipe body 1.

[0026] Furthermore, the rotating rod 22 is movably connected to the conveying pipe body 1, and one end of the rotating rod 22 away from the first conical tooth 23 is fixedly connected to the output end of the motor 24. The first conical tooth 23 and the second conical tooth 26 are both movable on the inner side of the connecting block 21. Through the arrangement of the first conical tooth 23 and the second conical tooth 26, when the first conical tooth 23 rotates under the action of the rotating rod 22, the second conical tooth 26 can rotate under the action of the first conical tooth 23 and drive the spiral conveying rod 25 to rotate, thereby realizing the conveying of concrete by the spiral conveying rod 25.

[0027] Furthermore, the connecting rods 27 are fixedly connected to the spiral conveying rods 25 in four groups, two groups of connecting rods 27 are correspondingly connected to the scrapers 28, and the crushing teeth 29 are evenly distributed on the inner surface of the scrapers 28.

[0030] Working principle: when in use, the motor 24 is electrically connected to an external power source, and the staff starts the motor 24 by pressing a switch. The operation of the motor 24 drives the rotating rod 22 to rotate, and the first conical teeth 23 rotate under the action of the rotating rod 22, and then the second conical teeth 26 rotate under the action of the first conical teeth 23 and drive the spiral conveying rod 25 to rotate. The rotation of the spiral conveying rod 25 can stably convey the concrete in the conveying pipe body 1. The connecting rod 27 drives the scraper 28 to rotate accordingly under the action of the spiral conveying rod 25.

By setting the crushing teeth 29, the scraper 28 can collide with the concrete during the rotation process, thereby breaking the agglomerated concrete, avoiding the condensation of the concrete, and thus preventing the conveying pipe body 1 from being blocked.

[0031] By connecting two groups of conveying pipe bodies 1 so that the first connecting pipe 3 enters the inner side of the second connecting pipe 31 and the positioning rod 36 is inserted into the inner side of the second fixing block 37, the connection of the conveying pipe body 1 can be positioned, and then by screwing the bolt 38 so that the bolt 38 enters the inner side of the positioning rod 36, the positioning rod 36 and the second fixing block 37 can be locked, thereby completing the splicing of the conveying pipe body 1. At this time, the first sealing gasket 32 ​​and the second sealing gasket 33 are in close contact, and the first connecting pipe 3 and the third sealing gasket 34 are in close contact, thereby achieving sealing of the splicing of the conveying pipe body 1.
