Power-driven return material clearing scraper conveying device

Abstract

The invention belongs to the field of machinery, and particularly relates to a power-driven return material clearing scraper conveying device. According to the conveying device, material clearing gearshafts are connected and fixed to material clearing transmission gears and hanging material clearing chain driving gears in a penetrating manner and are supported by machine frames or supported by lower material clearing hoppers, the material clearing transmission gears drive the hanging material clearing chain driving gears to rotate, return material clearing scrapers are arranged between two return material clearing scraper chains, and the return material clearing scraper chains are buckled on the hanging material clearing chain driving gears and material clearing reversing gear parts in asurrounding manner to form return material clearing scraper conveyors. The conveying device has the advantages that the material clearing transmission gears drive the hanging material clearing chain driving gears to rotate, so that the power for clearing return materials is saved, the active power on buckle tooth multi-dimensional integral leakage-proof side positioning bands is used as the powerfor clearing return coal, and therefore the power for clearing the return materials is increased, it is guaranteed that the power of the power-driven return material clearing scraper conveying deviceis reliable, the structure is simple, and the return material clearing effect is good.

Description

technical field

[0001] The invention belongs to the field of machinery, and in particular relates to a scraper conveying device driven by power for cleaning return materials. Background technique

[0002] The conveyor belt of the old belt feeder and the armor belt feeder is fed by the driving roller and the driven roller by friction. There are gaps in the perforation, there are gaps between multiple nails, etc., which are affected by tension, temperature, and the deflection of the rollers and rollers, etc., which will inevitably lead to the frequent deviation of the belt and nail belt during operation, resulting in material leakage and return. The material is serious and the leakage is serious. In order to solve the problems of material leakage and return material, a return material collector is added to the lower part of the feeder chassis. The old return material collector is driven by a separate power, with a complex structure and large volume and weight. Occupies a lot ...
