Preferably, the front side wall and the rear side wall of the positioning groove are perpendicular to the left side face and the right side face of the chain link main body, and the side wall of the positioning groove and the bottom of the groove are in circular arc transition. According to the optimization scheme, the arc transition is arranged, so that the stress at the corner is reduced, and the structural strength of the horizontal chain link is ensured; the front side wall and the rear side wall of the positioning groove are perpendicular to the left side face and the right side face of the chain link main body, the structure is simpler, and the contact area between the front side wall and the rear side wall of the positioning groove and the scraper blade insertion rod is guaranteed.
Preferably, one end of the boss, which is far away from the link body, is fixedly provided with the outline increasing plates, the area of the outline increasing plates is larger than the cross-sectional area of the boss, the two middle outline increasing plates and the middle boss form a T shape respectively, and the outline increasing plates at two ends and the bosses at two ends form an L shape respectively. This optimization scheme has increased the area of contact with the coal through setting up the increase outline board, utilizes the increase outline board to delay the wearing and tearing of coal to the boss, and the part that utilizes the increase outline board to extend the boss simultaneously carries on spacingly to the inserted bar of scraper blade to realized the omnidirectional orientation to four directions of scraper blade inserted bar, further improved the reliability of relatively fixed between scraper blade and the chain.
Preferably, the profile increasing plate, the boss and the link main body are integrally formed. This optimization scheme will increase board, boss and chain link main part and set up to integrated into one piece spare, and the whole casting shaping of being convenient for has improved production efficiency, makes the intensity of horizontal chain link improve by a wide margin moreover.
The utility model has the advantages that: the left side and the right side of the chain link main body are respectively provided with the four bosses, so that the bending resistance weak point of the horizontal chain link is reduced, the wear resistance of the chain link is improved, and meanwhile, the adjacent bosses are utilized to form positioning grooves to reliably position the insertion rod on the scraper, so that the local excessive wear of the outer side surface of the chain link main body is avoided.
