The device comprises a back-trough pair guide mechanism, an impact supporting mechanism, a driving mechanism, an impact head and the like, wherein the back-trough pair guide mechanism comprises a rolling friction back-trough pair structure, an impact guide element and the like, the rolling friction back-trough pair structure comprises an upper rolling friction recess and a lower rolling friction recess, a power impact element drives the impact guide element and the like to reciprocate, the impact guide element is placed in a space occupied by an external guide rolling body, the impact guide element increases the correcting height and the like of the impact head, and the rolling friction back-trough pair structure and the impact guide element correct the reciprocating movement direction of a toothholder.

Description

technical field [0001] The invention belongs to the field of machinery, and is especially applicable to a method for increasing and / or widening a backing groove to straighten an impact head in the field of mining or construction machinery and to implement the method by using a back groove to increase and / or widen a righting impact head device. Background technique [0002] Coal shearers, roadheaders, and excavators are collectively referred to as mining machines. Reciprocating impact mining machines and reciprocating impact excavators are used in the upper and lower parts of the impact guide to quickly and efficiently mine rocks or coal seams or cement concrete or hardened mudstone. Both are equipped with guide rolling bodies, because the upper and lower rolling bodies need to occupy a large space, so the size of the impact guide supporting the righting impact head is relatively reduced, resulting in insufficient strength to support the righting impact head, so that the impa...

AI Technical Summary

Problems solved by technology

For example, the reciprocating impact shearer must have a certain amount of undercover excavation in order to match the flexible scraper conveyor used for reloading, and it must also have sufficient top cutting in order to facilitate the smooth advancement of the hydraulic support. Therefore, the impact head must be set There is a certain height, that is, the impact head must be made larger and heavier, but when the larger and heavier impact head hits the material, it will contact the material with a large area at one time, so that the reaction force is concentrated and strong, and the impact reaction force is transmitted to the guide mechanism, The driving mechanism and the rear of the fuselage are easy to damage the guiding mechanism and the driving mechanism, prematurely damage the impact power box, etc., and easily cause the impact reaction force to resonate with the fuselage to deform the fuselage. Serious losses caused by the inability of the equipment to work continuously. In order to solve the above-mentioned problems, the present invention proposes a method of increasing and / or widening the back groove to straighten the impact head and implementing the method by using the heightening and / or widening of the back groove Righting the impact head device, which greatly reduces the height and / or width of a single impact head, realizes the purpose of mining lower materials by a single impact head and combining multiple smaller impact heads to use the same power source, saving energy and reducing consumption and improving efficiency
