Material channeling prevention device of small powder hopper for producing dry-mixed mortar

Abstract

The invention discloses a hopper anti-channeling device for producing dry-mixed mortar type small powder, which comprises a hopper body, a sieving plate, a triangular limiting ring and a fixing ring, the sieving plate is mounted on the inner wall of the hopper body, the triangular limiting ring is mounted on the inner wall of the hopper body, and the triangular limiting ring is positioned above the sieving plate; a fixing ring is installed on the outer surface of the hopper body, and a telescopic pipe is installed at the bottom of the hopper body. An annular pressure reducing plate is mounted at the top of the triangular limiting ring, and a conical pressure reducing cylinder is mounted at the top of the annular pressure reducing plate. The hopper is provided with an anti-material-channeling structure, the phenomenon of material spraying in the hopper body can be effectively avoided, impurities can be separated in advance when materials fall down in the hopper body, so that the purity of the materials entering the feeding pipe is improved, the feeding pipe can be subjected to self inclination adjustment according to the actual height of a material receiving mechanism placed at a discharging pipe opening, and therefore the feeding efficiency is improved. And finally, the distance between the annular pressure reducing plate and the hopper body is changeable.

Description

technical field [0001] The invention relates to the technical field of powder hoppers, in particular to a small-sized powder hopper anti-channeling device for producing dry powder mortar. Background technique [0002] In the production process of dry powder mortar, various materials need to be put into the mixing tank and mixed together, and then bagged through the hopper. The distance between the hoppers is a fixed value, and there are support rods around it. It is inconvenient to place the material receiving mechanism below it. Therefore, it is necessary to equip the hopper with a mechanism to transfer the position of the outlet, and a mechanism to prevent material channeling is required to improve the hopper. its own practicality. [0003] The defects of the existing powder hopper are: [0004] 1. The prior art CN111908167A discloses an outdoor heavy-duty powder hopper, "including a hopper, a discharging device, a plug-in board, and a bracket. The hopper is welded on th...
