Novel screening scraper reversed loader

Abstract

The invention discloses a novel screening scraper reversed loader. The screening scraper reversed loader comprises a machine body, wherein the machine body comprises a machine head, a first middle groove, a second middle groove, a third middle groove and a machine tail, the second middle groove comprises a second middle plate and a second bottom plate, the second middle plate comprises a left plate and a right plate, the opposite side edges of the left plate and the right plate do not make contact, the first middle groove comprises a first middle plate and a first bottom plate, a plurality ofscreening holes are formed in the working face of the first bottom plate, the screening holes are arranged in the length direction of the first bottom plate, and the hole diameters of the plurality ofscreening holes are gradually increased in the movement direction of a lower chain of a scraper chain. The novel screening scraper reversed loader has the beneficial effects that a traditional designthat materials are conveyed through an original upper chain way is changed into lower chain way conveying, namely, the second middle plate of the second middle groove is open, the materials can directly fall onto the second bottom plate of the second middle groove from the position above the second middle groove, the materials are conveyed through a lower chain way, the materials are prevented from being sheared and broken by a scraper when falling from the upper chain way in the screening process, and the particle size damage rate of material screening is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of coal mining and conveying devices, in particular to a novel screening scraper transfer machine. Background technique [0002] Material screening and transfer technology has always been one of the key research technologies for bulk objects in the stages of sorting and washing. Traditional screening and transfer equipment generally consists of two parts: screening equipment and transfer equipment. The system is relatively complicated, and the screening The screening capacity of the equipment or the matching degree of the transfer capacity of the transfer equipment cannot be optimal, resulting in waste of resources. The existing screening and reloading machine uses the upper chain to transport materials, and the screening holes are set on the upper chain. When the screening materials fall from the screening holes, the screening materials are easily transported by the upper and lower chains with opposite runn...

[0002] Material screening and transfer technology has always been one of the key research technologies for bulk objects in the stages of sorting and washing. Traditional screening and transfer equipment generally consists of two parts: screening equipment and transfer equipment. The system is relatively complicated, and the screening The screening capacity of the equipment or the matching degree of the transshipment capacity of the transshipment equipment cannot be optimal, resulting in waste of resources

The existing screening and reloading machine uses the upper chain to transport materials, and the screening holes are set on the upper chain. When the screening materials fall from the screening holes, the screening materials are easily transported by the upper and lower chains with opposite running directions. The scraper is sheared and broken, resulting in a high particle size damage rate of the screened material
