Problems solved by technology

However, the multi-cylinder cone crushers currently on the market are all fixed strokes, and the eccentric sleeve and the moving cone must be replaced to adjust the stroke, and it often takes a lot of time to replace it once, and many spare parts are added at the same time.

Embodiment 1

[0023] like Figure 1-5 As shown, this embodiment provides an adjustable stroke structure for a multi-cylinder cone crusher. The crusher includes a main shaft 1 and a shaft bushing 2; the shaft bushing 2 is installed on the outer surface of the main shaft 1; and the In the cavity of the crusher, the eccentric bushing 3, the pad bushing 4 and the convex spherical tile 5 are respectively installed from bottom to top; it also includes an eccentric component, a spherical tile seat 6 and a concave spherical tile 7; the eccentric component and the The outer surface of the shaft bushing 2 is matched and arranged between the shaft bushing 2 and the eccentric bushing 3; the eccentric assembly includes an eccentric bushing 8 and an eccentric outer circular bushing 9; the eccentric outer circular bushing 9 Installed on the outer surface of the eccentric sleeve 8; the lower part of the spherical shoe seat 6 is matched with the upper end of the main shaft 1, the upper part of the spherical...

Embodiment 2

[0026] like Figure 1-5 As shown, this embodiment is developed on the basis of the above-mentioned embodiment. Specifically, this embodiment provides an adjustable stroke structure for a multi-cylinder cone crusher. The flange 10 is provided with corresponding installation holes on the mounting flange, which are respectively connected to the large bevel gear and the balance ring of the crusher; the upper surface of the installation flange 10 is provided with an eccentric ring 11, and the eccentric ring 11 The outer diameter of the eccentric ring 11 is smaller than the outer diameter of the mounting flange 10, and the eccentric ring 11 balances the centrifugal force generated by the moving cone when the main engine is running; The larger the eccentric value of the eccentric component, the greater the throughput of the equipment. The eccentric value can be adjusted by adjusting the installation angle of the eccentric outer cylindrical bush 9 and the eccentric sleeve 8, that is, ...

Embodiment 3

[0034]This embodiment is developed on the basis of the above-mentioned embodiment. Specifically, this embodiment provides a specific stroke adjustment method of the stroke adjustment structure of a multi-cylinder cone crusher, as follows:

[0035] like Figure 1-5 As shown, the eccentric outer circle bushing 9 and the eccentric outer circle 8 are connected by keys. In this embodiment, a 30 degree offset angle is provided with six key grooves 13 with different angles. When adjusting the stroke, the eccentric outer circle is rotated. The bushing 9 is used to adjust the installation angle. Rotating the eccentric outer circular bushing 9 will cause the change of the eccentric angle A. The larger the eccentric angle A, the greater the throughput of the equipment, and the greater the stroke, the smaller the diameter of the crushed material. ,Depend on Figure 5 As shown in the figure, from left to right, from top to bottom, in order of non-rotated, rotated 30 degrees, rotated 60 de...

Abstract

The invention provides an adjustable stroke structure of a multi-cylinder cone crusher. The adjustable stroke structure comprises an eccentric assembly, a spherical tile seat and a concave spherical tile, the eccentric assembly is matched with the outer surface of the shaft bushing and is arranged between the shaft bushing and the eccentric bushing; the eccentric assembly comprises an eccentric sleeve and an eccentric outer circle lining. The eccentric outer circle lining is installed on the outer surface of the eccentric sleeve. The lower portion of the spherical tilting fillet is matched with the upper end of the spindle, and the upper portion of the spherical tilting fillet is matched with the lower portion of the concave spherical tile. And the spherical tilting fillet is in conical fit with the tilting fillet bushing. The stroke adjustment of the multi-cylinder cone crusher is realized by adopting a double-eccentric structure, the matching form of the spherical tilting fillet and the tilting fillet bushing is improved, and the stroke adjustment can be realized by changing the mounting angles of the eccentric excircle bushing and the eccentric bushing, so that the stroke adjustment can be realized without replacing the tilting fillet bushing and the eccentric bushing, the adjustment mode is simplified, and the adjustment efficiency is improved. And the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of mine crushing equipment, in particular to a stroke adjustment structure of a multi-cylinder cone crusher. Background technique [0002] Cone crusher is the most widely used mining machinery in the mining crushing industry, especially the multi-cylinder cone crusher is more popular. The multi-cylinder cone crusher has the advantages of large output, low energy consumption, long life and stable performance, but also has certain difficulties in design and manufacture. One of the important parameters of the multi-cylinder cone crusher is the stroke, which directly affects the output size and the load power of the main engine. When crushing different materials, the energy required by the crusher is different, so multi-cylinder cone crushers with different strokes should be selected for different materials. However, the multi-cylinder cone crushers on the market currently have a fixed stroke. To adjust the stroke, the ...
