Problems solved by technology

[0002] At present, the impact device is indispensable in coal mining sites. Its main function is to impact the relatively hard part of the coal and crush the hard object through impact. The existing impact device is mainly driven by hydraulic pressure. The speed of the power source is relatively slow, so the impact effect is poor, and because it needs liquid as a medium, its overall mass is large, which is not convenient to use

Abstract

The invention discloses an impact device for production of coal mines. The impact device comprises a main rod-shaped outer casing, wherein the side surface of the bottom part of the main rod-shaped outer casing is provided with a connecting plate structure which is integrated with the main rod-shaped outer casing. The impact device has the advantages that the initial driving of power is realized under the action force between an electromagnet and a permanent magnet; under the cooperation function of a main spiral spring, the splitting action can be quickly and effectively performed; the impactdevice is driven under the function of a plurality of electromagnetic elements, so that the power strength is high, the driving force is strong, and the practicality is strong; by arranging an objectelastic clamping and fixing mechanism at the bottom part, the splitting object can be fixed at the premises of no influence to splitting; by arranging an annular array type electromagnetic power driving mechanism, the strong push force is produced onto the circumference surface of the driven object, so that the power driving force is enhanced; by arranging an annular array type magnet passive driving mechanism, the magnetic field produced by the electromagnet can be converted into power, so as to complete power drive.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to an impact device for coal mining. Background technique [0002] At present, the impact device is indispensable in coal mining sites. Its main function is to impact the relatively hard part of the coal and crush the hard object through impact. The existing impact device is mainly driven by hydraulic pressure. The speed of the power source is relatively slow, so the impact effect is poor, and because it needs liquid as a medium, its overall mass is large, which is not convenient to use. Contents of the invention [0003] The object of the present invention is to provide an impact device for coal mine exploitation to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an impact device for coal mine exploitation, comprising a main rod-shaped casi...
