Multiple-cylinder rolling bearing hydraulic cone crusher

Abstract

The invention relates to the field of mining equipment, especially to a multiple-cylinder rolling bearing hydraulic cone crusher. The multiple-cylinder rolling bearing hydraulic cone crusher comprises the following components: a frame, a transmission mechanism, an eccentric mechanism, a moving cone set and a moving cone anti-reverse rotation mechanism. According to the invention, the frame comprises a lower frame and an upper frame; the transmission mechanism, the eccentric mechanism, the moving cone set and the moving cone anti-reverse rotation mechanism are all installed on the lower frame; the transmission mechanism is connected with the eccentric mechanism; the lower end of the moving cone set is arranged inside 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 set. The multiple-cylinder rolling bearing hydraulic cone crusher is characterized in that the space of the lower frame is reasonably arranged and the axial angle of a fixed cone can be adjusted by the upper frame, so as to change the size of a crushing cavity. Eccentric rotation and swing of the moving cone set are also stable.

Description

Technical field [0001] The invention involves the field of mining equipment, especially a multi -cylinder rolling bearing liquid crusher. Background technique [0002] Multi -cylinder rolling bearing liquid crusher crusher is a mining machine for crushing stone. The principle is to drive the eccentric mechanism through the transmission mechanism.For crushing stone.However, there are the following shortcomings of the existing multi -cylinder rolling bearing liquid compression cone crusher: 1. The lower frame structure of the existing multi -cylinder cone type crusher is unreasonable, resulting in inconvenient installation of eccentricity and transmission mechanism, and it is easy to transmission.The phenomenon of departure; 2. The upper racks of the existing cone crusher can only be used for feeding, and cannot adjust the axial height of the fixed cone; therefore, in order to adjust the size of the crushing cavity, it is used to break the sizes of different sizes.The cone crusher ...

AI Technical Summary

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.
