Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

As shown in fig. 1 and 2, the embodiment of the utility model discloses a waste rock blocking device which is arranged at a baffle plate 101 at one side of a coal spitting point corresponding to a scraper conveyor 100. This waste rock blocking device includes: a foundation plate 10, a movable coal baffle plate 20 and a telescopic cylinder 30.

The lower portion of the base plate 10 is attached to the rear side of the baffle plate 101 fixed to the scraper conveyor 100, and the base plate 10 is provided with a plurality of reinforcing ribs 12 in the area near the baffle plate 101, the plurality of reinforcing ribs 12 being horizontally arranged for increasing the strength of the base plate 10.

The movable coal blocking plate 20 is arranged on the rear side of the foundation plate 10, the telescopic cylinders 30 are arranged on two sides of the movable coal blocking plate 20, the lower ends of the telescopic cylinders are hinged to the foundation plate 10, and the upper ends of the telescopic cylinders 30 are hinged to the movable coal blocking plate 20. The telescopic cylinder 30 may be a hydraulic oil-driven cylinder, a pressure gas-driven cylinder, or an electric cylinder driven by a motor. When a gangue material (coal) falls onto the scraper conveyor 100 at a high height, as shown in fig. 2, the telescopic cylinder 30 is extended in advance to drive the movable coal blocking plate 20 to rise, thereby increasing the stopping height to prevent the gangue material from escaping to hurt people, and when the gangue material falls onto the scraper conveyor 100 at a low height only, the telescopic cylinder 30 is retracted in advance to reduce the stopping height, for example, as shown in fig. 1, the telescopic cylinder 30 is fully retracted.
