Example Embodiment

[0068] In order to further simplify the adjustment process of the elevation angle of the pick 11, in the present invention, the elevation angle adjustment mechanism can be arranged on the rotation angle adjustment mechanism. After the rotation angle adjustment mechanism adjusts a certain rotation angle, the elevation angle adjustment mechanism is rotated relative to the rotation angle adjustment mechanism. To realize the adjustment of the elevation angle. Based on this, as an embodiment of the elevation angle adjustment mechanism of the present invention, the elevation angle adjustment mechanism may include a second reference portion 23 and a second adjustment portion 24, wherein: the second reference portion 23 is provided on the first adjustment portion 22, and the The second reference portion 23 has a second axis parallel to the inclined plane 211 and perpendicular to the first axis; the second adjusting portion 24 is used to install the cutting assembly 1, that is, the cutti...

Abstract

The invention relates to the technical field of cutting test, and specifically relates to a cutting test device. The device comprises an angle adjustment mechanism, and the angle adjustment mechanism is used for installing a cutting assembly with cutting teeth and a tooth seat. Moreover, the angle adjustment mechanism can adjust at least one of the rotating angle, the pitching angle and the chamfering angle of the cutting teeth on the angle adjustment mechanism. The setting of the angle adjustment mechanism enables the device provided by the invention to flexibly change the installation parameters of the cutting teeth according to the actual cutting demands (different coal and rock characteristics), thereby achieving the effective research of the matching between the installation parameters of the cutting teeth and the actual cutting demands, and facilitating the improvement of the working performance of the device.

Description

technical field [0001] The invention relates to the field of cutting test technology, in particular to a cutting test device. Background technique [0002] The cutting device is an important part of construction machinery used for coal and rock mining and other working media such as roadheaders. It usually includes cutting head body, gear seat, pick, material guide plate, water nozzle and other components. Among them, The tooth seat is arranged on the cutting head body in the form of a helix, and the pick is installed on the tooth seat for crushing working media such as coal and rock. The nature of the working medium is different, resulting in differences in the characteristics of the working medium, the installation parameters of the pick (chamfer, elevation angle and rotation angle), and the movement parameters of the pick. Therefore, in order to better design the cutting device for different working media , so that the pick installation parameters can be reasonably match...
