Title:
FULLY-MECHANIZED COAL MINING FACE CROSSHEADING FLEXIBLE SCRAPER REVERSED LOADER
Document Type and Number:
WIPO Patent Application WO/2024/060594
Kind Code:
A1
Abstract:
A fully-mechanized coal mining face crossheading flexible scraper reversed loader. Middle slots of a reversed loader body are connected by a first dumbbell pin, the reversed loader body comprises a climbing section (4) and a landing section (10), the landing section is located at the bottom of a roadway, the height of the climbing section is raised obliquely upward towards a head (3), and a crusher is arranged between the climbing section and the landing section. One side of the crusher is connected to the middle slot at the climbing section by means of a second dumbbell pin, the other side thereof is connected to the middle slot at the landing section by means of a third dumbbell pin, and the head is connected to the middle slot at the climbing section by means of a fourth dumbbell pin; the head is connected to a belt self-moving tail (1) by means of a pushing device (2), the belt self-moving tail is provided with a slideway (13), and the climbing section and the head are in lap joint connection with the slideway of the belt self-moving tail. According to the described reversed loader, on the basis of the means of flexible connection between the internal components, the height of the head part of the reversed loader is reduced on the basis of implementing connection and displacement between the head and the belt self-moving tail, the displacement distance of the reversed loader is prolonged, and the production efficiency of a coal mine is improved.
