Problems solved by technology

However, the existing multi-cylinder cone crusher has the disadvantages of the following two aspects: 1. The internal space design of the lower frame of the existing cone crusher is unreasonable, resulting in the need to separately set up two lubricating oil circuits for lubricating the transmission mechanism and eccentric mechanism, thereby increasing the technological complexity of the lower frame of the cone crusher, and at the same time reducing the body strength of the lower frame of the cone crusher; 2, the existing upper frame of the cone crusher can only be used for feeding, not Adjust the axial height of the fixed cone; therefore, in order to adjust the size of the crushing cavity to crush stones of different sizes, the existing cone crusher is also equipped with a hydraulic lifting mechanism for changing the axial height of the movable cone group; but in Under the hydraulic lifting mechanism, the control accuracy of the size of the crushing cavity of the cone crusher is not high, and the maintenance cost of the large hydraulic lifting mechanism is too high

Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] like Figure 1~Figure 8 The frame of a multi-cylinder cone crusher shown includes a lower frame 1 and an upper frame 2 .

[0029] The following content describes each part of the cone crusher in detail:

[0030] lower rack

[0031] The lower frame is composed of a lower frame outer cylinder 11, a lower frame inner cylinder 12 arranged at the center of the lower frame outer cylinder 11, and a root connecting the lower frame inner cylinder 12 and the lower frame outer cylinder 11. The transmission pipe 13 is integrally connected with a plurality of frame ribs 14 . The cross-section of the upper end port side wall of the lower frame outer cylinder 11 is V-shaped with the opening facing downward, and the bottom of the outer wall surface of the lower frame outer cylinder 11 protrudes outwards to be provided with an outer cylind...

Abstract

The invention relates to the field of mining equipment, and particularly relates to a multi-cylinder cone crusher rack. The multi-cylinder cone crusher rack comprises a lower rack and an upper rack. The lower rack of the multi-cylinder cone crusher rack is simple in structure, and an internal oil path is reasonable in design; and the upper rack can adjust the axial height of a fixed cone, thereby changing the size of a crushing cavity.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a multi-cylinder cone crusher frame. Background technique [0002] The multi-cylinder cone crusher is a kind of mining machinery used for crushing stones. Its principle is to crush stones through the mutual cooperation between the moving cone and the fixed cone that rotates through the swing; between the moving cone and the fixed cone is the cone crusher. crushing cavity. The existing cone crusher includes a frame, and a transmission mechanism, an eccentric mechanism and a moving cone group installed inside the frame. The frame is divided into a lower frame and an upper frame, wherein the lower frame is mainly used for installing the transmission mechanism and Eccentric mechanism, the upper frame is mainly used for feeding and installing the fixed cone liner. However, the existing multi-cylinder cone crusher has the disadvantages of the following two aspects: 1. The internal spa...
