In the building materials, metallurgy, coal, chemical and other industries, can be used along the horizontal or inclined direction from the storage bin to the crusher, conveyor or other working machinery to transport all kinds of block or loose materials, is an indispensable equipment in the process of raw material treatment or continuous production, especially suitable for the operation of large and sharp materials. The conveyor trough plate of the plate feeder is directly in contact with the material to be transported, and the conveyor trough plate is the main part of the heavy duty apron feeder. With the increasing scale of modern engineering, the selection of heavy duty apron feeder specifications and models are also increasing, and the requirements for the molding structure of the conveyor trough plate are also increasing.
The purpose of the design is to provide a heavy duty apron feeder conveyor plate that can improve the conveyor efficiency and better sealing. The two ends of the feeding groove plate of the plate are respectively large arc and small arc raised upward, and the outer convex surface of the small arc is consistent with the inner concave surface of the large arc. ] The beneficial effect of the technology: when used, for two adjacent conveyor groove plates, a small arc of a conveyor groove plate extends into the large arc of another conveyor groove plate, so that the outer convex surface of the small arc contacts the inner concave surface of the large arc. During operation, the friction between the convex arc and the conveying material increases, and the large arc of the groove plate is superimposed on the small arc, which has better sealing and can effectively prevent material leakage and improve the conveying efficiency.
The concrete implementation method is that the double arc conveying groove plate is respectively presented as a large arc 1 and a small arc at both ends, and the outer convex surface of the small arc is consistent with the inner concave surface of the large arc. When used, for two adjacent conveyor groove plates, a small arc of a conveyor groove plate extends into the large arc of another conveyor groove plate, so that the outer convex surface of the small arc contacts the inner concave surface of the large arc.
The double circular groove plate structure designed by heavy duty apron feeder can realize the forming of the double circular groove plate by using the oil press. The upper and lower die tools are fixed on the fixed body and sliding body of the hydraulic press respectively. The raw materials of the groove plate are heated, and the spindles are pushed into the molding space by using the spindles to open the hydraulic press to press the raw materials of the groove plate to the requirements of the drawing of the groove plate.
The use of circulating water can effectively prevent the mold deformation caused by the heating of the groove plate: the forming upper and lower molds can be manufactured in sections to meet the molding requirements of the groove plate with different widths and pitch: the forming upper and lower molds and fetal molds can be disassembled and replaced to meet the molding requirements of the groove plate with different pitch. Greatly save the investment cost.
