Description

Technical Field

[0001] The utility model relates to an arch breaking device for a silo, belonging to the field of powder transfer and transportation. Background Art

[0002] Powder materials are prone to bridging and rat holes in silos due to their characteristics, resulting in poor discharge. Therefore, arch breaking devices are often installed in silos. An arch breaking paddle shaft driven by a motor is installed in the lower part of the silo. Multiple column rods are installed on the surface of the arch breaking paddle shaft. The arch breaking paddle shaft with column rods is driven by a motor to rotate at the bottom of the silo. This is one of the ways to deal with poor discharge of powder materials. Because the bottom of the silo is a conical structure that is wide at the top and narrow at the bottom, the column rods cannot be too long, otherwise the longer column rods will interfere with the inner wall of the silo, resulting in the powder material near the lower end of the silo near the discharge port cannot be loosened, that is, the arch breaking range is small, affecting the arch breaking effect. Therefore, it is necessary to design a silo arch breaking device that expands the arch breaking range. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide an arch breaking device for a silo to solve the problems raised in the above-mentioned background technology. The utility model has a large arch breaking range.

At the same time, the first V-shaped blade installed on the arch-breaking paddle shaft swings between the conical lower silos. Because the lower end of the first V-shaped blade can extend to the lower position of the conical lower silo, and the two oblique sides of the first V-shaped blade are close to the inner edge of the conical lower silo, the powder material in the conical lower silo can be loosened in multiple places, thereby expanding the arch-breaking range.
