Horizontal spiral material collecting type vertical spiral car unloader

Abstract

The invention discloses a horizontal spiral material collecting type vertical spiral car unloader which comprises a movable portal, a horizontal spiral mechanism, a vertical spiral mechanism, a lifting mechanism and a sealing bin, a horizontal spiral material collector is installed on one side of the bottom end of the vertical spiral mechanism, and a fixed scraper blade is installed on the other side of the bottom end of the vertical spiral mechanism; and the bottom end of the vertical spiral mechanism is further provided with a movable scraper device, and the movable scraper device is located on the side, away from the vertical spiral mechanism, of the horizontal spiral material collector. The invention provides the horizontal spiral material collecting type vertical spiral car unloader which is high in stability, the power of the whole machine is reduced, the working reliability is improved, residual materials in a carriage are reduced to the minimum, and therefore materials at corners in the carriage can be thoroughly cleaned.

Description

technical field [0001] The invention relates to the technical field of car unloading equipment, and more specifically relates to a horizontal spiral collecting type vertical spiral car unloading machine. Background technique [0002] When transporting materials in train carriages, the single transport volume is large and the cost is low. However, in work practice, the loading and unloading of some bulk materials such as coal, sand and gravel is not only labor-intensive but also very low-efficiency. Bulk material unloading equipment for trains, such as dumpers, chain bucket unloaders, excavators, horizontal screw unloaders, vertical screw unloaders, etc., all have the problem of residual material clearance. [0003] Compared with the dumper, the wagon body of the screw unloader is basically not damaged when unloading coal, and it has good adaptability to general models. The length of the unloading line, the amount of coal received and the output capacity can be flexibly sele...

Problems solved by technology

[0005] However, in the above-mentioned patent, since the vertical screw mechanism is a 3-layer mechanism, the outer layer collector collects the materials in the compartment to the feeder. The material on the outer layer of the vertical screw mechanism cannot be collected, resulting in material residues at the corners of the carriage, incomplete cleaning, and inability to collect materials close to the corners at a close distance, and the collection efficiency is low
