Description

Technical Field

[0001] This utility model relates to the field of ore crusher technology, specifically an ore crusher with an adjustable end cover liner structure. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain usable properties. When ore is mined, it is fed into a crusher for rapid crushing in order to facilitate subsequent transportation and processing. During the crushing process, the ore will cause wear on the inner wall shell of the crusher, so liners need to be added.

[0003] In the process of ore crushing, ore crushers with adjustable end cover liner structures are required. Existing ore crushers mostly have fixed end cover liners. When processing ores with high hardness or large particle size, the fixed angle of the liner may lead to insufficient crushing force and incomplete crushing of the ore. On the other hand, for ores with low hardness or small particle size, it may cause over-crushing, increasing energy consumption and affecting subsequent mineral processing. In addition, in the existing crushers, the uneven force on the ore in the crushing chamber during the crushing process also affects the crushing quality. Therefore, an ore crusher with an adjustable end cover liner structure is proposed to solve the problems mentioned above. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This embodiment of an adjustable end cap liner structure ore crusher includes a body 1, a feed hopper 2 fixedly connected to the outside of the body 1, a mounting frame 3 fixedly connected to the top of the body 1, a fixed liner 4 fixedly connected to one side of the inside of the body 1, a crushing roller 5 rotatably mounted on the body 1, and a movable liner 6 disposed on the other side of the inside of the body 1. An adjustment mechanism for reciprocating swing of the movable liner 6 is provided on the outside of the body 1 and extends into its interior. A pressing device is provided on the upper surface of the body 1 and extends into its mounting frame 3. The adjustment mechanism includes a drive motor 7 fixedly mounted on the back of the body 1, a rotating shaft 8 fixedly connected to the output shaft of the drive motor 7, a swing arm 9 fixedly connected to the outside of the rotating shaft 8, and a drive rod 10 hinged to the outside of the swing arm 9.

[0025] The end of the drive rod 10 furthest from the swing arm 9 is hinged to the back of the moving liner 6, which is rotatably connected to the inside of the machine body 1 via a hinge seat. When the tilt angle of the moving liner 6 needs to be adjusted according to the characteristics of the ore, the drive motor 7 is started by the controller. The output shaft of the drive motor 7 drives the rotating shaft 8 to rotate, and the swing arm 9 on the rotating shaft 8 begins to swing in a circular motion. The swing of the swing arm 9 drives the drive rod 10, which is hinged to it, to move. The end of the drive rod 10 furthest from the swing arm 9 is hinged to the back of the moving liner 6, thereby pushing the moving liner 6 to rotate around its hinge point with the inside of the machine body 1, realizing the reciprocating swing adjustment of the tilt angle of the moving liner 6.

[0026] In this embodiment, the pressing device includes a pressure plate 11 slidably connected inside the mounting frame 3, a connecting column 12 fixedly connected to the top of the pressure plate 11, a horizontal plate 13 fixedly connected to the top of the connecting column 12, a moving rod 14 fixedly connected to the bottom of the horizontal plate 13, a pulley 15 rotatably connected to the outer surface of the bottom end of the moving rod 14, and a transmission mechanism disposed inside the body 1.

[0027] The transmission mechanism includes a mounting base 16 fixedly connected to the inner wall of the body 1, a guide seat 17 fixedly connected to the top of the mounting base 16, a guide shaft 18 slidably connected to the inside of the guide seat 17 and extending to its outside, a protrusion 19 fixedly installed on the outside of the guide shaft 18, a slide groove 20 opened inside the protrusion 19, a connecting shaft 21 fixedly installed on the outside of the protrusion 19, and a rotating rod 22 rotatably installed on the connecting shaft 21. The end of the rotating rod 22 away from the connecting shaft 21 is rotatably connected to the swing arm 9 through a pin.

[0028] Specifically, the mounting base 16 is fixedly installed on the inner wall of the machine body 1 by bolts. There are two guide seats 17, which are symmetrically distributed on the top of the mounting base 16. The machine body 1 has a moving hole that matches the guide shaft 18. A return spring 23 is fixedly installed between the left mounting base 16 and the protrusion 19. The return spring 23 is connected to the outside of the guide shaft 18. When the swing arm 9 swings in the opposite direction, the protrusion 19 returns to its original position under the action of the return spring 23. The moving rod 14 drives the pressure plate 11 to move upward and return to the initial position, realizing the reciprocating up and down movement of the pressure plate 11. This allows the ore crusher to adjust the shape of the crushing chamber and the force angle of the moving liner 6 according to the hardness, particle size and other characteristics of different ores, thereby improving the crushing effect on different types of ores and enhancing the adaptability of the equipment.

[0029] It should be noted that the pulley 15 is slidably connected to the inside of the chute 20, and the outer diameter of the pulley 15 matches the inner diameter of the chute 20. The moving rod 14 is slidably connected to the inside of the machine body 1 via the pulley 15. A guide rod 25 is fixedly connected to the top of the machine body 1, and a limiting seat 24 is fixedly connected to the back of the moving rod 14. The limiting seat 24 has a limiting hole inside that matches the guide rod 25, and the limiting seat 24 is slidably connected to the outside of the guide rod 25. During the crushing process, when the swing arm 9 swings, it drives the protrusion 19 to move through the rotating rod 22 and the connecting shaft 21. The chute 20 on the protrusion 19 cooperates with the pulley 15, causing the moving rod 14 to drive the pressure plate 11 to move downward within the mounting frame 3, pressing down on the ore and enhancing the crushing effect.

[0030] In addition, the pressure plate 11 is slidably connected to the inside of the mounting frame 3 via the moving rod 14, and the outer diameter of the pressure plate 11 is adapted to the inner diameter of the mounting frame 3.

[0031] In this embodiment, a servo motor is fixedly installed on the back of the machine body 1, and the output shaft of the servo motor is fixedly connected to one end of the crushing roller 5. A feeding port is opened inside the machine body 1, and four support legs are fixedly installed at the bottom of the machine body 1.

[0032] The working principle of the above embodiments is as follows:

[0033] In operation, ore enters the machine body 1 through the feed hopper 2. The controller starts the servo motor to drive the crushing roller 5 to rotate, and the controller also starts the drive motor 7 to work. Its output shaft drives the rotating shaft 8 and the swing arm 9 to rotate, which in turn drives the hinged drive rod 10 to move. The drive rod 10 pushes the movable liner 6, which is hinged to it, to rotate around the hinge seat, realizing the reciprocating swing adjustment of the tilt angle of the movable liner 6. When the swing arm 9 swings, the rotating rod 22 connected by the pin shaft rotates, which drives the protrusion 19 on the connecting shaft 21 to move. The sliding groove 20 in the protrusion 19 cooperates with the pulley 15, so that the moving rod 14 drives the pressure plate 11 to slide up and down in the mounting frame 3, pressing down on the ore to assist in crushing. When the swing arm 9 swings in the opposite direction, the return spring 23 causes the protrusion 19 to return to its original position, driving the moving rod 14 and the pressure plate 11 back to their initial positions, realizing the reciprocating motion of the pressing device. The ore is crushed under the combined action of the movable liner 6, the fixed liner 4, the crushing roller 5 and the pressure plate 11, and the crushed ore is discharged from the discharge port.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.

[0035] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
