AI Technical Summary
Traditional scraper conveyors typically use scrapers made entirely of steel, which results in issues such as heavy weight, susceptibility to corrosion, high energy consumption, and short lifespan, making it difficult to meet the needs of weight-sensitive conveying scenarios.
The design combines a metal skeleton with a polymer plastic material body. The metal skeleton provides strength, while the polymer plastic material body covers and forms a plate-like structure with through holes and through holes. Combined with injection molding process, it forms a lightweight and corrosion-resistant scraper.
It achieves a 30%-50% reduction in scraper weight, reduces equipment energy consumption and wear, extends service life, improves the overall integrity and reliability of the scraper, and adapts to stable operation under harsh working conditions.

Abstract
Claims
1. A flight for use on a flight conveyor, characterized in that include: A metal frame (10) having at least two through holes (11) located on both sides of the length direction of the metal frame (10); A polymer plastic material body (20) is wrapped around the outside of the metal skeleton (10) to form a plate-like structure. The polymer plastic material body (20) has through holes (23) on both sides of its length direction. The through holes (23) correspond to the through holes (11) and are used to connect the chain of the scraper conveyor.
2. The scraper according to claim 1, characterized in that, The through holes (11) include a plurality of holes, which are spaced apart along the length of the metal frame (10).
3. The scraper according to claim 1, characterized in that, The polymer plastic material body (20) is formed on the outer wall of the metal skeleton (10) by casting or injection molding process.
4. The scraper according to claim 1, characterized in that, Grooves (22) are provided in the two oppositely arranged scraper main surfaces (21) formed by the polymer plastic material body (20) along the length direction of the scraper main surfaces (21).
5. The scraper according to claim 4, characterized in that, The groove (22) includes a main groove (221) and a secondary groove (222) formed on both ends of the main groove (221), wherein the secondary groove (222) is positioned to overlap with the through hole (11), and the area of the secondary groove (222) is larger than the area of the through hole (11).
6. The scraper according to claim 5, characterized in that, The recess depth of the secondary groove (222) on the main surface (21) of the scraper is greater than the recess depth of the main groove (221) on the main surface (21) of the scraper.
7. The scraper according to claim 1, characterized in that, The polymer plastic material body (20) is high-density polyethylene.
8. The scraper according to claim 1, characterized in that, The metal skeleton (10) is made of Q345 steel.
9. The scraper according to claim 1, characterized in that, Two demolding ramps (242) are formed in the two oppositely arranged scraper sides (24) formed by the polymer plastic material body (20). The structure of each scraper side (24) is such that one of the scraper side sides (24) is inclined towards the scraper main surface (21) at the central axis (241) in the length direction.
10. An apron conveyor characterized in that Includes the scraper as described in any one of claims 1 to 9.
