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 mechani...

Embodiment 1

[0088] Figure 1 to Figure 4 It is the method for strengthening the righting impact head with the back groove in embodiment 1 and the device for strengthening the righting impact head with the back groove for implementing the method. The device for strengthening the righting impact head with the back groove includes the back groove guide mechanism 37, the impact support mechanism 12. Driving mechanism 9, impact head 3, etc., impact head 3 includes gear seat 4, etc., anti-back groove guide mechanism 37 includes rolling friction anti-back groove structure 10, impact guide 7, etc., rolling friction anti-back groove structure 10 includes upper Rolling friction grooves 22, lower rolling friction grooves 22, etc., upper rolling friction grooves 22, lower rolling friction grooves 22 include guide rolling bodies 6, etc., impact guides 7 include upper impact guides 5, lower impact guides 2 etc., the upper impact guide 5 and the lower impact guide 2 are respectively fixed at both ends o...

Embodiment 2

[0107] Figure 5 It is the use of backing grooves to strengthen the righting impact head device described in embodiment 2. The difference from embodiment 1 is that the upper arc-shaped rolling friction groove 13 and the lower arc-shaped rolling friction groove 14 are arranged on the tooth seat 4 and the upper impact guide 5. In the U-shaped guide frame 15 formed by the lower impact guide 2 or in the frame-shaped guide frame 38 or cylindrical guide frame, the gear seat 4 buckles the upper impact guide 5 and the lower impact guide 2 in the upper arc correspondingly. Type rolling friction groove 13, lower arc rolling friction groove 14, etc., power impact member 8 drives gear seat 4 or upper impact guide 5, lower impact guide 2, etc. to reciprocate, upper impact guide 5, lower impact guide 2. Under the support of the upper arc-shaped rolling friction groove 13 and the lower arc-shaped rolling friction groove 14, the rolling friction reciprocating motion is realized, and the upper...

Embodiment 3

[0110] Figure 6 to Figure 7 It is the use of the opposite back groove to strengthen the righting impact head device described in embodiment 3. The difference from embodiment 1 is that the rolling elements 16 on the upper part of the upper impact guide 5 and the lower rolling elements 16 on the lower impact guide 2 are reduced. The height of the back groove guide mechanism 37, thereby reducing the height of the tooth seat 4, etc., using the back groove guide mechanism 37 to reduce the number of rolling elements 16, etc., make a larger impact head 3 smaller or cut the impact A single tooth seat 4 with the same cutting height is divided into multiple tooth seats 4, the single-layer impact head 3 with the same impact cutting height is changed to a combination of multi-layer impact heads 3, etc., and each small impact head 3 of the combined impact head 17 is used The same power source 18, etc., reduces the impact area of ​​each small impact head 3, the impact force is large, and t...

Abstract

The present invention relates to the field of machinery and provides an impact head strengthening and centralizing method by using dual back recesses and an impact head strengthening and centralizing device by using dual back recesses for applying the method, and the method and the device are particularly applicable to the fields of mining or engineering machinery. The device comprises a dual back recess guidance mechanism, an impact support mechanism, a drive mechanism and impact heads, etc. The dual back recess guidance mechanism comprises a rolling friction dual back recess structure and impact guidance elements, etc. The rolling friction dual back recess structure comprises an upper rolling friction grove and a lower rolling friction groove. A power impact element drives the impact guidance elements to reciprocate. The impact guidance elements are disposed within the space of an external guidance roller. The impact guidance elements increase the centralizing height of the impact heads, and are in rolling friction with the reciprocating movement direction of the dual back recess structure and centralizing tooth holders of the impact guidance elements.

Description

technical field [0001] The invention belongs to the field of machinery, and is particularly applicable to a method for reinforcing a righting impact head with a back groove and a device for implementing the method using a back groove to strengthen a righting impact head, which are suitable for the field of mining or engineering machinery. 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 impact pow...
