AI Technical Summary

Technical Problem

Existing screw conveyor devices are prone to clogging during walnut processing, making it difficult to separate impurities online, causing kernels to break easily, and the grid plates to become clogged, resulting in low production efficiency and poor purity of the finished product.

Method used

It adopts anti-clogging components, air separation and impurity removal mechanism, flexible cleaning components and double helix differential speed material conveying mechanism. It achieves anti-clogging, online impurity removal and dynamic cleaning through unblocking holes, blowers, fans and flexible rubber comb teeth, respectively, and reduces breakage by differential rotation.

Benefits of technology

It effectively prevents clogging, achieves online impurity removal, improves the purity of finished products, reduces nut breakage, and enhances production efficiency and product quality.

Abstract

This invention discloses an anti-breakage spiral conveyor for walnut processing, relating to the technical field of walnut processing equipment. It includes a conveying chamber, an air-separation and impurity removal mechanism, an anti-clogging component, and a flexible cleaning component. A material guide channel is installed at the rear end of the upper surface of the conveying chamber, an air-separation and impurity removal mechanism is installed on the rear end surface, a discharge chute is opened on the front end surface and connected to a discharge slide plate, and a chip discharge chamber is connected to the lower surface. An anti-clogging component is installed inside the material guide channel. A grid plate is installed on the bottom surface inside the conveying chamber, and a double-spiral differential speed material discharge conveyor is installed in the center of the chamber. A flexible cleaning component is installed at the upper end inside the chip discharge chamber, and the flexible cleaning component is positioned opposite to the grid plate. The anti-clogging component prevents material blockage during feeding, the air-separation and impurity removal mechanism separates light impurities online, the double-spiral differential speed conveying reduces material breakage, and the flexible cleaning component automatically cleans the grid plate. This achieves integrated anti-clogging, impurity removal, anti-breakage, and self-cleaning functions for walnut conveying, effectively improving conveying efficiency and product quality.
