Pneumatic vibration device for high-frequency vibration coal conveying of raw coal hopper

Abstract

The invention discloses a pneumatic vibration device for high-frequency vibration coal conveying of a raw coal hopper. The device comprises a coal hopper and an annular fixing plate, a plurality of air hammers are arranged on the annular fixing plate, a re-rapping device is arranged on a hammer rod of each air hammer, and a plurality of rapping resonance devices are arranged on the outer wall of the coal hopper; the re-rapping devices comprise slide ways, plungers slidably connected with the inner wall of the slide was, guide rods arranged on the side wall of the plungers, sleeves arranged at the far end of the guide rods, elastic driving components arranged on the outer wall of the guide rods in a sleeving mode, and airflow driving components arranged on the outer wall of the air hammers and magnetic attraction fixing components arranged on the outer wall of the hammer rods in a sleeving mode; and the rapping resonance devices comprise hammering blocks, warping plates fixed to the side wall of the coal hopper through a bearing seat and a plurality of resonance components arranged on the outer wall of the coal bucket in a sleeving mode, the bottom end of the warping plates are connected with the hammering blocks through first elastic reset components, and the top of the warping plates are connected with the side wall of the coal hopper through second elastic reset components. According to the vibrating device, high-frequency vibrating can be conveniently conducted on the raw coal hopper, and high-frequency vibrating can be conveniently conducted on the whole coal hopper.

Description

technical field [0001] The invention mainly relates to the technical field of dredging devices for raw coal scuttles, in particular to a pneumatic vibrating device for high-frequency vibration coal transportation of raw coal scuttles. Background technique [0002] When the raw coal scuttle is transporting coal, the coal scuttle will be blocked due to the accumulation of coal material in the coal scuttle and the large amount of moisture in the coal material, which will have a huge impact on processing and production. [0003] According to the suspension rapping integrated coal scuttle provided by the patent literature with the application number CN201220315940.6, it can be known that the product includes a beating cylinder, a hammer head, a hammering support and a self-unloading coal scuttle. The curved and inverted hyperbolic coal bucket sections are alternately connected, and the coal bucket sections are connected by welding. The upper end of the self-unloading coal hopper...
