Problems solved by technology

Since the upper belt of the conveyor belt is a plane or very shallow concave surface during transportation, the gangue in the consignment cannot be piled up too thick, otherwise a large amount of gangue will be scattered from the machine head or fall from the conveyor belt during operation, so the current Belt conveyors cannot store a large amount of gangue

Embodiment Construction

[0020] Such as figure 1 As shown, a belt type storage and transportation machine on the excavation working face, it is arranged with an upper idler 7 and a lower idler 7.1 at a certain distance on the frame 4, and a conveyor belt 6 is arranged on the idler, and the structure of the frame 4 There are rotary drums at both ends, wherein one end of frame 4 is gangue unloading rack 1.2, and the rotary drum installed on gangue unloading rack 1.2 is unloading drum 1.1, and the other end of frame 4 is tail rack 5.1, and the tail rack 5.1 is The installed rotary drum is the tail drum 5.2; a tensioning frame 3.1 is provided under the frame 4, and two tensioning drums are installed on the tensioning frame 3.1, which are respectively the movable first tensioning drum 3.2 and the guide rail for guiding. The second tensioning cylinder 3.3; the bottom of the frame 4 is provided with a driving frame 2.1, and the driving drum 2.2 is installed on the driving frame 2.1; 8 Install the baffle pla...

Abstract

The invention discloses a belt type storing and conveying machine and a method for storing and conveying gangue for an underground heading face. Upper carrier rollers and lower carrier rollers are arranged on a rack at intervals; rotary drums are arranged at the two ends of the rack; a pair of driving drums and tensioning drums are arranged below the rack; the driving drums are dragged by a driving device to rotate; vertical supports are fixedly connected to the two sides of the rack at intervals; material blocking plates are arranged on the vertical supports so as to enable groove-type spaces to be formed above the conveying belt; and the driving device is composed of a permanent magnet direct-current driving frequency conversion speed regulating motor and a frequency converter, wherein the motor is in rigid linkage with the driving rollers through elastic pin couplings. When the gangue is output from the heading face, the groove type spaces of the storing and conveying machine running at a low constant speed are filled with the gangue sent to the machine. When storage is full, the machine stops running and waits for being unloaded; when a tunnel conveying system is free in coal conveying, the stored gangue can be rapidly unloaded to the tunnel conveying system of, and therefore time conflict between outputting the gangue from the heading face and outputting coal of a working face is solved, and the tunneling efficiency is greatly improved.

Description

technical field [0001] The invention relates to a transportation device and a storage device for an underground driving face in a mine, and is an integrated device used for centralized storage and centralized transportation of coal gangue produced by driving ahead. Background technique [0002] At present, the raw coal produced by each coal mining face and the gangue produced by each excavation face in the underground coal mine must be transported to the main and auxiliary shafts through the transportation roadway. During transportation, gangue is sometimes mixed into the raw coal transportation system, resulting in a decline in the quality of raw coal and increasing the burden of ground washing. [0003] For this reason, it is best not to transport gangue when coal mines are transported, and to transport coal in priority; therefore, the tunneling face can only be excavated when coal is not transported, which has resulted in the gangue of the previous excavation cycle. If t...
