Abstract

The invention relates to the field of mining equipment, in particular to a multi-cylinder rolling bearing hydraulic cone crusher. A multi-cylinder rolling bearing hydraulic cone crusher, including a frame, a transmission mechanism, an eccentric mechanism, a moving cone group and a moving cone anti-rotation mechanism; the frame includes a lower frame and an upper frame, a transmission mechanism, an eccentric mechanism, Both the moving cone group and the moving cone anti-reverse rotation mechanism are installed on the lower frame, the transmission mechanism is connected with the eccentric mechanism, the lower end of the moving cone group is set in the eccentric mechanism, and the upper end of the moving cone anti-reverse rotation mechanism is connected with the lower end of the moving cone group ;The space setting of the lower frame of the multi-cylinder rolling bearing hydraulic cone crusher is reasonable; the upper frame can adjust the axial height of the fixed cone, thereby changing the size of the crushing cavity; the eccentric swing of the moving cone group is stable.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a multi-cylinder rolling bearing hydraulic cone crusher. Background technique [0002] The multi-cylinder rolling bearing hydraulic cone crusher is a kind of mining machinery used for crushing stone. Its principle is to drive the eccentric mechanism through the transmission mechanism, and the eccentric mechanism drives the moving cone group to rotate and swing, and through the mutual cooperation between the moving cone group and the fixed cone frame. For crushing stones. However, the existing multi-cylinder rolling bearing hydraulic cone crusher has the following disadvantages: 1. The lower frame structure of the existing multi-cylinder cone crusher is unreasonable, which leads to inconvenience in the installation of the eccentric mechanism and the transmission mechanism, and is prone to transmission failure. 2. The upper frame of the existing cone crusher can only be used for fe...

Problems solved by technology

However, the existing multi-cylinder rolling bearing hydraulic cone crusher has the following disadvantages: 1. The lower frame structure of the existing multi-cylinder cone crusher is unreasonable, which leads to inconvenience in the installation of the eccentric mechanism and the transmission mechanism, and is prone to transmission failure. 2. The upper frame of the existing cone crusher can only be used for feeding materials, and the axial height of the fixed cone cannot be adjusted; therefore, in order to adjust the size of the crushing chamber to crush stones of different sizes, The cone crusher is also equipped with a hydraulic lifting mechanism for changing the axial height of the moving cone group; however, 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; 3. The eccentric mechanism includes a bearing seat and an eccentric bushing, and the eccentric bushing is positioned in the bearing seat through the bearing; however, the contact between the eccentric bushing and the bearing is offset, and the positioning effect is not good, and the bearing misalignment is prone to occur, and the eccentric bushing is damaged 4. The installation stability of the moving cone group of the cone crusher is insufficient, which is specifically reflected in the fact that the moving cone is set on the moving cone shaft, and the circumferential direction between the moving cone and the moving cone shaft is not fixed, which is prone to deflection and loosening; 5. The connection between the moving cone group and the eccentric mechanism is only to position the lower end of the moving cone shaft in the eccentric sleeve through the bearing. During the swinging process of the moving cone group, the balance of the moving cone group is insufficient, resulting in the rotation The pendulum amplitude is unstable, the size of the crushed stone particles is different, and the crushing effect is not good; 6. The lower end of the moving cone group of the existing multi-cylinder cone crusher is not equipped with a moving cone anti-rotation mechanism, which leads to the rotation of the moving cone group. The direction is not fixed, it is easy to cause the material to slip, and the crushing effect of the stone is not good.
