Roller assembly of sand screening machine

Abstract

The invention discloses a roller assembly of a sand screening machine. The roller assembly comprises a screen drum body (1). A spiral coil (2) is arranged on the inner wall of the screen drum body (1), a steel plate (3) is welded to the end face of one end of the screen drum body (1), a rotation shaft (4) which is concentric with the screen drum body (1) is arranged in the screen drum body (1), one end of the rotation shaft (4) is fixedly connected with the steel plate (3), the other end of the rotation shaft (4) is fixedly connected with a driven belt wheel (5) in a sleeved mode, the driven belt wheel (5) is connected with a driving belt wheel (6) through a belt (7), and the driving belt wheel (6) is installed on an output shaft of a motor (8). The roller assembly is simple in structure and convenient to use. Due to the fact that sand and stone entering the screen drum body can be effectively screened step by step, the economic benefit of screened sand is increased, pebbles entering the positions nearby the tail end are automatically discharged through an outlet, the overall automation degree is increased, the overall working efficiency is increased, abrasion of the ends of a roller is reduced, and the overall service life is prolonged.

Description

technical field [0001] The invention relates to the field of processing and manufacturing construction tools, in particular to a drum assembly of a sand screening machine. Background technique [0002] At present, the overall structure of the common sand screening machines in the market is relatively complicated, and there are many transmission parts between them, so the probability of mechanical failure during operation is increased to a certain extent, and most of the common drum sand screening machines are With the straight cylinder design, the pebbles trapped in the drum cannot be automatically discharged during use, and it is very troublesome to clean up, and the screening effect is poor. Contents of the invention [0003] The object of the present invention is to provide a sand screening machine drum assembly, which can effectively solve the problems in the background technology. [0004] In order to solve the existing problems in the background technology, it inclu...
