Invention herewith described refers to the amortization rubber coating for prevention of belt conveyor slipping at pouring bulk materials consisting of two parts (1, 2) with parallel helical spiral grooves wherein a series of grooves (5) is taller and wider achieving greater surface contacts with the belt conveyor, and on its surface has notches (6), for draining water and dirt, preventing the generation of adhesive residue on the belt conveyor, providing good belt conveyor seating and non-slippage despite unequal pouring of material hence the grooves (5) slightly bend and lower parallel grooves (7, 4) receive that as well as extra water and dirt on the left and right side of the herringbone merging (3) by turning the roller that makes the belt conveyor to create the pressure on the liquid in the channels of the lower grooves (7, 4) so that the excess overflows through the notches (6), and drains from the contact surfaces, tangentially from the roller.
