Embodiment

[0033] like figure 1 As shown, a method for improving underground coal mining transmission efficiency of the present invention includes a coal belt conveyor 1 and a baffle plate 2, and the coal belt conveyor 1 can adopt a fixed general-purpose belt conveyor of the Jinding Coal Machine DTII (A) type: DTⅡ(A) general-purpose new series general-purpose belt conveyor is an updated series after the first revision after optimization and absorption of domestic and foreign advanced technologies on the basis of DTⅡ general-purpose series. Widely used in coal, mining, metallurgy, port, power station, building materials, petroleum, chemical industry, light industry and other industries. It only needs 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.

[0034] The conveyor belt 3 of the coal belt conveyor 1 is uniformly inlaid with multiple rows of electromagnet blocks 4, the conn...

Abstract

The invention discloses a method for improving underground cold mining conveying efficiency. A coal belt conveyor and baffle blocks are adopted. A plurality of rows of electromagnet blocks are evenly embedded to a conveyor belt of the coal belt conveyor, the thickness of each electromagnet block is equal to that of the conveyor belt, and smooth transmission of the conveyor belt on rollers of the coal belt conveyor cannot be affected by embedding of the electromagnet blocks. Connection line poles of the electromagnet blocks are arranged on one side of the conveyor belt. Connection lines poles of a coal conveying segment of the conveyor belt are provided with electric brushes. A baffle block pushing device is arranged at the position, corresponding to the conveyor belt, of the lower end of the coal belt conveyor, the baffle block pushing device pushes the baffle blocks to the conveyor belt, and the baffle blocks are connected with the powered-on electromagnet blocks in an attraction manner. The conveyor belt of the coal belt conveyor is provided with the baffle blocks which are circularly separated, the conveying efficiency of the coal belt conveyor can be improved by three times, and the phenomenon that coal slides easily is solved well.

Description

technical field [0001] The invention relates to the coal mining field, in particular to a method for improving underground coal mining transmission efficiency. Background technique [0002] As we all know, in the current process of coal mining and transportation in our country, the mined coal is usually transported by means of belt transportation with an included angle. High and difficult to maintain; on the other hand, the existing design of the conveying device has a certain angle (from the mining face to the ground) in the process of conveying coal, so the phenomenon of coal slipping occurs, not only the conveying efficiency is low, but also the mining workers Personal life causes potential safety hazards. How to solve the above problems to improve transportation efficiency and reduce mining costs is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and th...
