Embodiment

[0027] like figure 1 As shown, an efficient transmission device for underground coal mining of the present invention includes a coal belt conveyor 1 and a baffle block 2. The coal belt conveyor 1 can be a fixed universal belt conveyor of Jinding Coal Machine DTII (A) type: DTII (A) General-purpose new series general-purpose belt conveyor is an updated series based on the DT II general-purpose system, which has been optimized and absorbed domestic and foreign advanced technology for the first time. Widely used in coal, mining, metallurgy, ports, power stations, building materials, petroleum, chemical, light industry and other industries. It is only necessary to further improve the transmission belt of the DTII (A) type fixed universal belt conveyor, which is convenient to implement, low in cost and high in efficiency.

[0028] The conveyor belt 3 of the coal belt conveyor 1 is evenly inlaid with multiple rows of electromagnet blocks 4. The connection poles 5 of the electromagn...

Abstract

The invention discloses an efficient transmission device for underground coal mining. The device comprises a coal belt conveyor and a baffle plate; multiple rows of electromagnets are uniformly inlaid in a conveying belt of the coal belt conveyor; the electromagnets are as thick as the conveying belt; the inlaying of the electromagnets cannot influence smooth transmission of the conveying belt on a roller of the coal belt conveyor; connecting wire poles of the electromagnets are arranged on one side of the conveying belt; electric brushes are arranged on the connecting wire poles of a coal conveying section of the conveying belt; a baffle plate pushing device is arranged at the lower end, opposite to the conveying belt, of the coal belt conveyor; the baffle plate pushing device pushes the baffle plate onto the conveying belt; and the baffle plate is connected with the electrified electromagnets in an absorption manner. The baffle plate capable of circularly separating is arranged on the conveying belt of the coal belt conveyor, so that the conveying efficiency of the coal belt conveyor can be improved by three times, and the phenomenon of easy slip of coals is preferably solved.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to an efficient transmission device for underground coal mining. Background technique [0002] As we all know, in the current process of coal mining and transportation in my country, the mined coal is usually transported by means of belt transportation with an included angle. High, difficult to maintain; on the other hand, the existing designed conveying device has a certain angle in the conveying distance (mining surface to the ground) in the process of conveying coal, and the phenomenon of coal slipping occurs, which not only has low conveying efficiency, but also affects mining workers. Personal safety hazards are caused. How to solve the above problems to improve transportation efficiency and reduce mining costs is an urgent problem to be solved at present. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and the...
