Adjustable mud-scraping truss for mud scraper

Abstract

The invention relates to an adjustable mud-scraping truss for a mud scraper. The truss is divided into a left section of truss structure and a right section of truss structure; the truss comprises upper and lower section steel which are arranged in parallel; connecting angle is spliced between the upper section steel and the lower section steel; the connecting angle is arranged slantways or vertically to form a Z-shaped structure or a V-shaped structure; connecting plates are arranged on the corresponding end parts of the left section of truss structure and the right section of truss structure; bolt holes are formed in the upper ends of the connecting plates; connecting lug plates are arranged at the lower ends of the connecting plates; the connecting lug plates are correspondingly hinged to lug plate supports arranged on a transmission shaft of the mud scraper; a U-shaped angle adjusting clamp is arranged on a mud scraper shaft; a screw rod with holes is arranged on the adjusting clamp; one end of the screw rod is rotationally connected with the connecting plates through nuts and the other end of the screw rod is hinged to the U-shaped angle adjusting clamp. Due to improvement of a mud-scraping bracket, the mud-scraping efficiency is greatly improved, the service life is prolonged and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a mud scraping truss for a bushing type mud scraper. Background technique [0002] The prior art mud scraper bracket generally includes a central shaft, which is fixedly connected to the tubular brackets on both sides of the central shaft. The central shaft is provided with a pin gear to drive the bracket to rotate through gear transmission. Due to its transmission mode It is gear driven, and its bracket is a fixed structure, and it can only be a pipe fitting, which cannot be adjusted up and down. It is difficult to adapt to the requirements of various clarifier bottoms, resulting in low mud scraping efficiency, and because it is a single-pipe structure, its strength is relatively high Low, short service life, needs to be improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a mud scraper bracket for a mud scraper that can realize up and down adjustment of th...
