Chain supporting wheel and lower part bend wheel of shallow slot separator

Abstract

The invention provides a chain supporting wheel and a lower part bend wheel of a shallow slot separator and belongs to the shallow slot separator fitting field. The chain supporting wheel and the lower part bend wheel of the shallow slot separator mainly comprise wheel hubs (1) and hub sleeves (2), wherein the wheel hubs (1) are in the shape of T; the hub sleeves (2) which are matched with the wheel hubs (1) are in the shape of a groove; inclined planes (6) are arranged inside of an outer edge of the wheel hubs (1); two wheel hubs (1) are installed in opposite directions at both ends of a shaft (4) through keys (3); the hub sleeves (2) are snapped on the wheel hubs (1) by using screws. End parts of the two wheel hubs form a trapezoid to prevent chain wheel deviation; the inclined planes on the wheel hubs can assist in preventing chain falling; chains slide on the hub sleeves when chains are started to run, and the wheel hubs and the shaft are driven to move; if any wearing exists, only the hub sleeves are needed to be replaced. According to the invention, current chain wheels can be replaced by the chain supporting wheel and the lower part bend wheel of the shallow slot separator. The invention is advantaged by a simple structure, convenient processing, low cost, high security, easy installation and easy replacing.

Description

technical field [0001] The invention relates to accessories of a shallow slot sorting machine, in particular to a chain support wheel and a lower redirecting wheel of the shallow slot sorting machine. Background technique [0002] Dense medium shallow tank separator is an ideal coal preparation equipment with simple structure, high efficiency and good separation effect. Its main working part is scraper chain. A set of support wheels is required between the chain from the head drive wheel to the tail tension wheel to support the sagging caused by the chain being too long. In the lower part of the tail of the tank body, the chain needs to have a set of reversing wheels before entering the slideway, so that the chain can enter the slideway horizontally after running downward. At present, the supporting wheel and the lower redirecting wheel used in the shallow slot sorting machine are all sprockets, and the more sprockets are used, the more accident points will occur in the ope...

AI Technical Summary

Problems solved by technology

The wear of the chain and the wear of the sprocket will cause the two to cooperate poorly, and it is easy to cause accidents such as off-chain, stuck chain or even broken chain.

Moreover, the processing cost of the sprocket is high, and the replacement and installation requirements are high, which brings difficulties to maintenance, not only requires a lot of manpower and time, but more seriously affects the normal operation of the equipment and even the operation of the entire system
