Anti-plugging concrete powder storage hopper

Abstract

The invention discloses an anti-plugging concrete powder storage hopper, which includes: a hand cranking scratch board mechanism, a storage inner cylinder, a storage outer cylinder, a material outputmechanism, a lower end communication pipe, a flange disk and a material discharge pipe; the hand cranking scratch board mechanism is installed on the side surface of the storage outer cylinder; the material output mechanism is located below the hand cranking scratch board mechanism and is mechanically connected to the storage outer cylinder; the lower end communication pipe is welded to the bottomof the storage outer cylinder; the bottom end of the lower end communication pipe is provided with the material discharge pipe; the flange disk is arranged on the outer surface of the material discharge pipe; the storage inner cylinder is movably installed inside the storage outer cylinder. By means of the hand cranking scratch board mechanism, storage inner cylinder, a sliding control mechanismand a wire clamping column, the material discharge pipe is free of plugging; in addition, a scratch board on the hand cranking scratch board mechanism can remove concrete powder on the storage inner cylinder or detach the storage inner cylinder for cleaning, so that the hand cranking scratch board mechanism can work stably without dislocation.

Description

technical field [0001] The invention is an anti-clogging concrete powder storage hopper, which belongs to the field of concrete production equipment. Background technique [0002] Ordinary concrete generally refers to the artificial concrete made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, densely formed and cured and hardened. Stone and concrete are mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete, in which sand and stone form a skeleton Function, called aggregate; cement and water form cement slurry, the cement slurry wraps on the surface of the aggregate and fills its gaps, before hardening, the cement slurry acts as a lubricant, endows the mixture with a certain degree of...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an anti-clogging concrete powder storage hopper to solve the problem of using a vibrator in the prior art to shake off the concrete on the inner wall of the storage hopper, but there will still be residues on the inner wall of the storage hopper. Generally, lime powder will be contained in concrete powder. If it has not been used for a long time, the lime powder will react with the moisture in the air to form lumps, which will stick to the inner wall of the storage hopper, which will not easily fall off and cause the powder to stick.
