Description

Technical Field

[0001] The utility model belongs to the technical field of silo equipment, in particular to a vibration arch-breaking device in an aggregate silo. Background Art

[0002] The silo consists of a silo body and a hopper located at the lower port. The silo is often used to hold aggregates and powdered materials. When the silo is in use, due to factors such as mutual squeezing and friction between the aggregates, the aggregates are easily arched at the discharge port of the hopper, resulting in the aggregates not being able to be discharged smoothly. In severe cases, the discharge port will be blocked. Therefore, it is necessary to set an arch breaking mechanism at the hopper to improve the smoothness and accuracy of aggregate discharge. Common arch breaking methods include manual arch breaking, mechanical arch breaking and vibration arch breaking.

[0003] Vibration arch breaking is a method of driving the vibration of the grid inside the hopper by the operation of a vibrating motor, thereby driving the aggregate inside the hopper to vibrate to achieve the purpose of preventing arching and breaking arches. In the prior art, for example, the arch breaking device and silo disclosed in Publication No. CN105366225A, the arch breaking device includes: a grid and a vibrator, the vibrator is installed on the grid, and is used to drive the grid to vibrate to achieve arch breaking of the material on the grid. In its technical solution, the grid is set at the upper port position of the hopper, and the arch breaking function of the material on the grid is achieved by the operation of the vibrator. However, the silo generally has a large volume, and the hopper below it also has a certain volume. Although its technical solution achieves the arch breaking work below the silo, that is, above the grid, after the aggregate after arch breaking falls into the hopper through the grid, the size of the lower end discharge port of the hopper is smaller than the size of the upper port of the hopper, resulting in the possibility of arching again inside the hopper, affecting the smoothness of the hopper's discharge.

[0004] Based on the deficiencies in the prior art, the utility model discloses a vibration arch-breaking device in an aggregate silo. A first vibration arch-breaking mechanism for breaking the arch of the aggregate at the lower end of the silo is arranged at the upper port of the hopper, and a second vibration arch-breaking mechanism for secondary arch-breaking of the aggregate in the hopper is arranged inside the hopper. While breaking the arch of the aggregate at the lower end of the silo, the aggregate in the hopper can be broken for the secondary time, thereby further improving the discharge smoothness of the hopper.
