Fixed anti-blocking loading hopper

Abstract

The invention relates to a fixed anti-blocking loading hopper which comprises a conical blanking hopper, a rotary material channel and a cylindrical material channel which are sequentially connected from top to bottom, and is characterized in that an anti-blocking mechanism is arranged in the rotary material channel; retracting and releasing driving assemblies are fixedly installed at the two ends of the cylindrical material channel. The rotating end of the folding and unfolding driving assembly is fixedly connected with a folding and unfolding supporting rod; a first-stage material distributing mechanism is fixedly connected to the lower portion of the folding and unfolding supporting rod and comprises a first material guiding table and a second material guiding table. And a second-stage material distribution mechanism is connected below the second material guide table. Through cooperation of the anti-blocking mechanism, the first-stage material distributing mechanism and the second-stage material distributing mechanism, the flow direction and distribution of the materials can be flexibly controlled while the materials are prevented from being blocked due to accumulation, different truck loading requirements are met, and therefore the bin flattening effect can be better achieved, and smoothness, stability and flexibility of the materials in the conveying and truck loading process are guaranteed.
