Material taking machine and material taking wheel bucket

Abstract

The invention relates to a material taking machine and a material taking wheel bucket. The material taking wheel bucket comprises a body, a front end lug plate, a first pin shaft, a first nut and a first anti-falling piece. When the material taking wheel bucket needs to be arranged on a bucket wheel disc, the first pin shaft penetrates through a first mounting hole and a lug hole, so that a firstlimiting flange of the first pin shaft abuts against a fixed beam; and the first nut is arranged at the other end of the first pin shaft in a sleeving mode, so that the front end lug plate is connected with the fixed beam of the bucket wheel disc, then the first anti-falling piece is inserted into a first anti-falling hole, and the first nut is prevented from loosening and falling off from the first pin shaft. In addition, if the material taking wheel bucket needs to be replaced, the first anti-falling piece is disassembled firstly, then the first nut is disassembled from the first pin shaft,and the first pin shaft is pulled out. Due to the fact that the diameter of the first pin shaft is smaller than the hole diameter of the first mounting hole, the first pin shaft can be conveniently disassembled from the material taking wheel bucket, the maintenance and replacement efficiency can be improved, meanwhile, the normal use of the material taking wheel bucket is not influenced, and the material taking wheel bucket can be prevented from falling off.

Description

technical field [0001] The invention relates to the technical field of port equipment, in particular to a reclaimer and a reclaimer wheel bucket. Background technique [0002] The reclaimer is an important storage yard operation equipment for coal and other materials. It is mainly composed of a traveling mechanism, a slewing mechanism, a pitching mechanism, a reclaiming wheel bucket, and a cantilever belt mechanism. In the coal wharf, the main function of the reclaiming wheel bucket is to take the coal on the yard to the ground belt for the ship loader to load the ship. [0003] Traditionally, the lugs on both sides of the front end of the reclaiming wheel bucket are connected to the bucket wheel disc with two long pins, and the lugs on both sides of the rear end of the reclaiming wheel bucket are fixed on the bucket wheel disc through short pins. After long-term use, corrosion occurred between the two long pins and the corresponding wheel lug hole and wheel hole. When repl...

Problems solved by technology

Although this method can improve the replacement and maintenance efficiency of the reclaiming wheel bucket, after the reclaiming wheel bucket has been replaced many times, the ear plates on both sides of the front end installed on the bucket wheel disc are the first installation of the reclaiming wheel bucket. The ear plates on both sides of the front end and the ear plates on both sides of the front end installed on the bucket wheel disc have been gas-cut and welded for many times, the joint strength of the weld seam is obviously reduced, which affects the normal use of the reclaiming wheel bucket, and there is a safety hazard of the reclaiming wheel bucket falling off
