Description

Technical Field

[0001] The utility model relates to the technical field of mineral crushing equipment, in particular to a cone crushing device used in a mineral processing process. Background Art

[0002] Ore dressing technology plays a vital role in the mining and utilization of mineral resources. One of the core links of the ore dressing process is crushing, which uses crushing equipment to process the raw ore into a particle size suitable for further processing or direct utilization.

[0003] Traditional cone crushing equipment usually directly crushes the ore once, and the overall efficiency of the equipment is not high. Ore particles of large or small size fall directly onto the screen. The subsequent mineral processing process still requires secondary crushing. In addition, the ore is easily accumulated on the screen after crushing, resulting in incomplete screening and frequent shutdown for cleaning, which affects production efficiency. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a cone crushing device for mineral processing, including a receiving frame with upper and lower openings, a fixed extrusion seat is fixed to the inner side wall of the receiving frame, a sliding extrusion seat slidably connected to the inside of the receiving frame is arranged on the opposite side of the fixed extrusion seat, a telescopic cylinder is arranged on the outer side of the receiving frame, a connecting rod deep into the receiving frame is fixed to the telescopic end of the telescopic cylinder, and the other end of the connecting rod is fixed to the sliding extrusion seat; an inverted cone-shaped conical crushing frame is fixed to the bottom of the receiving frame, a mounting rod is rotatably connected to the conical crushing frame, and multiple sets of rollers are fixed on the upper and lower outer sides of the mounting rod, and the outer diameter of the roller gradually decreases from top to bottom; a conical connecting frame is fixed to the bottom of the conical crushing frame, and a screen is fixed to the bottom of the conical connecting frame.

[0005] Furthermore, a collecting frame is fixed at the bottom of the conical connecting frame, a mounting rod extends into the collecting frame, a servo motor is connected to the bottom of the mounting rod, rollers rotatably connected to the collecting frame are arranged on both sides of the mounting rod, an eccentric cam is fixed on the outer side of the roller, and the outer side of the eccentric cam is in contact with the bottom of the screen.

[0006] Furthermore, a main bevel gear is fixed on the outer side of the mounting rod, a slave bevel gear meshing with the main bevel gear is fixed on the outer side of the roller, a protection box is arranged on the outer side of the servo motor, and the main bevel gear and the slave bevel gear are in the protection box.

[0007] Furthermore, a spreading rod is fixed on the mounting rod above the screen.

[0008] Furthermore, a feeding frame in an inverted cone shape is fixed on the top of the receiving frame.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. By setting a fixed extrusion seat and a sliding extrusion seat, the sliding extrusion seat moves toward the fixed extrusion seat under the drive of the telescopic cylinder to perform preliminary extrusion and crushing of the ore. By utilizing the internal stress of the ore, larger pieces of ore are crushed first, which greatly improves the efficiency of preliminary crushing and lays the foundation for subsequent fine crushing; the ore that has undergone preliminary crushing enters the conical crushing frame, and the servo motor drives the mounting rod to rotate, driving multiple sets of rollers to crush the ore finely. The outer diameter of the roller gradually decreases from top to bottom, so that the ore is continuously crushed and the uniformity of the crushed particle size is ensured; through the design of conical crushing frames with different outer diameters, the ore can be crushed to the required particle size under the action of the roller and then separated from the crushing frame, ensuring that the particle size of the crushed ore is uniform and meets the needs of different mineral processing processes.

[0011] 2. The setting of the push rod and eccentric cam ensures that the ore will not accumulate on the screen. The rotation of the push rod and the vibration of the screen further improve the screening effect and effectively avoid the problem of incomplete screening. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The ore to be crushed is fed into the receiving frame 2 through the feeding frame 1, and the telescopic cylinder 5 is started to drive the sliding extrusion seat 4 to move toward the fixed extrusion seat 3 through the connecting rod 6. The sliding extrusion seat 4 and the fixed extrusion seat 3 perform preliminary extrusion and crushing on the ore, and the internal stress is used to crush the larger pieces of ore; the ore that has been preliminarily crushed falls into the conical crushing frame 7, and the servo motor 13 is started to drive the mounting rod 8 to rotate, thereby driving the roller 9 to crush the ore in the conical crushing frame 7. According to the size of different ore that needs to be crushed, the outer diameter of the bottom of the conical crushing frame 7 can be designed in a targeted manner, so that the ore volume will not leave the conical crushing frame 7 until the crushing knife corresponds to the size.

[0022] After the ore falls through the conical crushing frame 7, it falls onto the screen 11 in the conical connecting frame 10. The finely crushed ore falls into the collecting frame 12 through the screen holes.
