Material bin discharging device

Abstract

A material-discharging apparatus of a material chamber. Strip-shaped protrusions (110) are arranged at intervals on the surface of the bottom (100) of the material chamber. Screw conveyor material-guiding mechanisms (200) are arranged in material-guiding grooves (120) formed between every two adjacent protrusions (110). The material-guiding grooves (120) are in communication with a material-discharging channel (310) accommodating a material-discharging mechanism (300). Rotary arch-breaking wheels (400) are arranged along sidewalls (121) of at least one side of the material-guiding grooves (120). The arch-breaking wheels (400) are rotatively supported on the sidewalls (121) of the strip-shaped protrusions (110). Paddling structures (401) are radially arranged on the peripheries of the rotary arch-breaking wheels (400). The paddling structures (401) are interference installed with moving parts (200) of the material-discharging apparatus. When moving, the moving parts (200) drive the arch-breaking wheels (400) into rotation for arch breaking. The material-discharging apparatus of the material chamber improves the fluidity of materials on the wall surface of the material chamber, thus preventing formation of arches on the wall surface structure of material chamber.

Description

technical field [0001] The invention relates to a bin discharging device for storing loose materials. Background technique [0002] The lower part of the existing silo is generally in a shrinking shape, and a discharge port or a discharge channel is set on the narrowed bottom surface to provide a gathering effect like a funnel. The arch is completely dependent on the contracted silo bottom structure at the bottom of the silo and it is difficult to export it from the discharge port. For this reason, people have proposed a kind of feed bin, as the utility model patent of publication number 202897570U. In this patent, the two sides of the bottom of the silo are tapered to form more than one longitudinal discharge channel, and an auger is longitudinally arranged at the bottom of the discharge channel. When the material falls to the bottom of the silo along the cone surface, the material falling into the bottom of the silo is output from the silo by the forced propulsion of the...

Problems solved by technology

[0005] Second, in the above-mentioned structure, although the arrangement is relatively dense, there will still be some materials remaining between the two screw propulsion devices. These remaining materials cannot be discharged for a long time, and will form serious arching under the action of continuous extrusion. , and form an extremely rough arched surface between the screw propulsion devices, the screw propulsion device located in between has to carry out the propulsion and export movement of materials in the channel formed by the rough arch surface, so that the materials entering the screw propulsion device or between them are more accurate It is easy to arch, which increases the resistance of the propulsion movement of the screw propulsion device, wastes energy consumption, and affects the discharge effect of the silo
