Problems solved by technology

[0002] The coal resource recovery rate of the existing top-coal caving process is low, which has something to do with the low recovery rate of floating coal in the existing top-coal caving scraper conveyor. The width of the middle groove of the existing scraper conveyor is limited, and the When the top coal falls, part of it must fall to the outside of the scraper conveyor and cannot be recovered. In order to solve this problem, the utility model of Chinese patent 02252297.2 discloses a recovery device for floating coal on the top of the scraper conveyor. A rigid box is added to the side, which widens the width of the scraper conveyor, thereby improving the recovery rate of floating coal; although this utility model solves the problem of floating coal recovery to a certain extent, it is still There are certain problems, not very reasonable

Embodiment

[0014] Example: see Figure 1-2 , a top-coal caving scraper conveyor with a movable coal collecting plate in the figure, the movable coal collecting plate is hinged on the upper edge of the baffle groove side of the middle groove of the scraper conveyor, and the movable coal collecting plate and the above-mentioned middle part A hydraulic cylinder is connected between the outer sides of the groove side of the groove baffle. The two ends of the hydraulic cylinder are respectively connected with the movable coal receiving plate and the middle groove through the hinge shaft. A hydraulic hose is connected to the hydraulic cylinder, and a bottom beam is provided at the bottom of the middle trough, and the bottom beam contains a trough-type bottom beam, and the trough-type bottom beam is buckled on the bottom surface of the middle trough, and the hydraulic soft The tubes are protected inside the channel sill. The center line of the hydraulic cylinder and the center line of the tro...

Abstract

The invention relates to a top-coal caving scraper conveyor with a movable coal-collecting plate. The side movable coal-collecting plate is articulated with the upper edge of one outer side of a middle trough of the scraper conveyor, and a hydraulic cylinder is connected between the lower surface of the side movable coal-collecting plate and the outer side of the middle trough. On the whole, the top-coal caving scraper conveyor with the side movable coal-collecting plate increases the coal resource recovery rate of the top-coal caving technology, and the movable top plate not only can enlarge the coal drop space but also can facilitate the recovery of coal flow.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery and equipment, in particular to a caving scraper conveyor with a movable coal receiving plate. Background technique [0002] The coal resource recovery rate of the existing top-coal caving process is low, which has something to do with the low recovery rate of floating coal in the existing top-coal caving scraper conveyor. The width of the middle groove of the existing scraper conveyor is limited, and the When the top coal falls, part of it must fall to the outside of the scraper conveyor and cannot be recovered. In order to solve this problem, the utility model of Chinese patent 02252297.2 discloses a recovery device for floating coal on the top of the scraper conveyor. A rigid box is added to the side, which widens the width of the scraper conveyor, thereby improving the recovery rate of floating coal; although this utility model solves the problem of floating coal recovery to a ...
