Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sand removal, in particular to an anti-blocking sand suction pump pipeline sand removal device. Background Art

[0002] Sand pumps are power equipment used for transportation. They are suitable for extracting various yellow sands, mineral sands, tailings slurries and other highly abrasive media in industrial and mining enterprises. The pipes used by sand pumps are often silted up by sand and soil. If they are not cleaned in time for a long time, the pipes will be seriously blocked.

[0003] The existing sand removal device can prevent the drill bit from getting stuck by the reciprocating contraction movement of the drill bit. For example, Chinese patent application No. CN202121694546.3 discloses a wear-resistant sand pump pipeline dredging device, including an installation box, an installation chamber and a water chamber are provided in the installation box, a telescopic rod is arranged on the installation box, a moving component is arranged at the output end of the telescopic rod and is used for moving the installation box, a hollow shaft is slidably connected to the installation box, a diversion box is fixedly connected to the hollow shaft, and a drill bit is fixedly connected to the diversion box.

[0004] This device drives the moving wheel through a motor, so that the moving wheel drives the device to move, and at the same time, the moving wheel is squeezed by a sliding rod so that the moving wheel is close to the inner wall of the pipe. The structure is relatively complicated. At the same time, the moving wheel needs to be pressed each time before using the device so that the device can enter the pipe, which makes the operation inconvenient. Utility Model Content
