Problems solved by technology

The existing 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 the 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 upper frame of the existing cone crusher can only be used for feeding , the axial height of the fixed cone cannot be adjusted; 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 under the hydraulic lifting mechanism, the control accuracy of the size of the crushing chamber 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] Such as Figure 1~Figure 8 The shown cone crusher includes a frame, and a transmission mechanism 3 , an eccentric mechanism 4 , a moving cone group 5 and a moving cone anti-rotation mechanism 6 arranged inside the frame. The frame 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 1 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 connection between 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 to form. The cross-section of the upper end port side wall of the lower frame outer cylinder 11 is V-s...

Abstract

The invention relates to the field of mining equipment, in particular to a cone crusher. A cone crusher, including a frame, and a transmission mechanism, an eccentric mechanism, a moving cone group, and a moving cone anti-rotation mechanism arranged inside the frame; the frame includes a lower frame and an upper frame; the lower frame The internal space is designed reasonably, and the lubricating oil circuit is gathered to the oil storage chamber of the inner cylinder for lubricating the eccentric mechanism and the transmission mechanism, thereby simplifying the design of the internal oil circuit; the upper frame can adjust the axial height of the fixed cone, thereby changing the crushing chamber. size.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a cone crusher. Background technique [0002] Cone crusher is a kind of mining machinery used for crushing stones. Its principle is to crush stones through the mutual cooperation between the movable cone and the fixed cone that rotates through the swing; between the movable cone and the fixed cone is the cone crusher. crushing cavity. The existing 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 the 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 upper frame of the existing cone crusher can only be use...
