Description

Technical Field

[0001] This utility model relates to the field of ore processing technology, and in particular to an ore crushing device. Background Technology

[0002] A crusher is a pulverizing machine used in the processing of metallic and non-metallic minerals to break mined raw ore into small particles through compression and bending. This equipment is widely used in mining, construction, and metallurgy industries, and is of great significance for improving production efficiency and saving costs. Existing ore crushers mostly use two crushing wheels rotating in opposite directions to achieve the crushing effect. However, in actual use, because the distance between the two adjacent crushing wheels cannot be adjusted, a single machine often can only crush the ore into one size. Different processing requirements and different types of ore have different requirements for the size of the crushed ore, resulting in poor versatility, high operating costs, and limitations. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing an ore crushing device that can perform multi-size crushing of ores.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an ore crushing device, comprising,

[0005] The crusher casing contains two rotatable crushing wheels;

[0006] Arc-shaped grooves are formed on both sides of the crusher casing, and both ends of one of the crushing wheels are rotatably and slidably disposed in the corresponding arc-shaped grooves;

[0007] A displacement control mechanism, rotatably mounted on the crusher housing, is used to drive the corresponding crushing wheel to move in the arc groove, so as to move it closer to or away from another crushing wheel.

[0008] A transmission mechanism, which is mounted on the crusher housing, is used to drive two crushing wheels to rotate simultaneously in opposite directions.

[0009] Furthermore, the crusher housing includes a shell, with an inlet at the top and an outlet at the bottom of the shell, and the crushing wheel located between the inlet and the outlet. Uncrushed ore enters the shell through the inlet, and crushed ore is discharged out of the shell through the outlet.

[0010] Furthermore, the telescopic end of the displacement control mechanism is provided with a mounting base, and the end of the crushing wheel near the displacement control mechanism is rotatably connected to the mounting base.

[0011] Furthermore, the transmission mechanism includes a motor mounted on the crusher housing, which drives another crushing wheel to rotate. A rotating column is rotatably mounted on the inner wall of the crusher housing, located at the center of an arc-shaped groove. Two transmission belt groups are mounted on the rotating column. Each transmission belt group consists of a first transmission wheel, a second transmission wheel, and belts mounted on and engaging with the two transmission wheels. A mounting frame is rotatably mounted on one of the crushing wheels. The first transmission wheels in both transmission belt groups are coaxially mounted on the rotating column. The second transmission wheel in one transmission belt group is coaxially mounted on the other crushing wheel driven by the motor. The second transmission wheel in the other transmission belt group is rotatably mounted on the mounting frame, and both the second transmission wheel and the corresponding crushing wheel are coaxially equipped with meshing gears. Another arc-shaped groove centered on the rotating column is formed on the inner wall of the crusher housing. A pin is mounted on the mounting frame, and the pin is slidably inserted into the pin.

[0012] Furthermore, a downwardly inclined guide plate is provided on the inner wall of the crusher casing. The guide plate is located at the top of both sides of the two crushing wheels and is used to guide the ore into the middle between the two crushing wheels.

[0013] The beneficial effects of this utility model are reflected in:

[0014] This invention utilizes a displacement control mechanism. The moving end of the mechanism extends or retracts, causing the corresponding crushing wheel to move within an arc-shaped groove. This movement moves the crushing wheel closer to or further away from the other crushing wheel, altering the distance between them. A smaller distance results in finer ore particles, while a larger distance results in coarser particles. Once the distance is adjusted to the desired value, the ore is fed into the crusher casing. The transmission mechanism then activates, causing both crushing wheels, adjusted to different distances, to rotate in opposite directions, thus crushing the ore to the required size for practical use.

[0021] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-4 This utility model discloses an ore crushing device, including a crusher shell 1, two crushing wheels 2 are rotatably installed inside the crusher shell 1, and arc-shaped grooves 3 aligned with each other are opened on both sides of the crusher shell 1. Both ends of one of the crushing wheels 2 are rotatably and slidably installed in the corresponding arc-shaped groove 3.

[0023] In one embodiment, a displacement control mechanism 7 is rotatably mounted on the crusher housing 1. The displacement control mechanism 7 may be a hydraulic push rod. The displacement control mechanism 7 is used to drive the corresponding crushing wheel 2 to move in the arc groove 3, so that it moves closer to or away from the other crushing wheel 2. The crusher housing 1 is also provided with a transmission mechanism, which is used to drive the two crushing wheels 2 to rotate simultaneously in opposite directions.

[0024] In practice, by activating the displacement control mechanism 7, the moving end of the displacement control mechanism 7 extends or retracts, thereby driving the corresponding crushing wheel 2 to move in the arc-shaped groove 3. The crushing wheel 2 will move closer to or further away from the other crushing wheel 2, thereby changing the distance between the two crushing wheels 2. When the distance is smaller, the crushed ore particle size becomes finer; when the distance is larger, the crushed particle size becomes coarser. After the distance is changed to the required value, the ore is put into the crusher casing 1, and then the transmission mechanism is activated. The transmission mechanism enables the two crushing wheels 2, which are adjusted to different distances, to rotate in opposite directions, thereby crushing the ore to the required size for practical use.

[0025] In one embodiment, the crusher housing 1 includes a housing 11, with an inlet 12 and an outlet 13 at the top and bottom of the housing 11, respectively, and the crushing wheel 2 is located between the inlet 12 and the outlet 13.

[0026] With this design, when the ore needs to be crushed, the uncrushed ore enters the shell 11 through the inlet 12, and then the ore is crushed by two rotating crushing wheels 2. The crushed ore is then discharged out of the shell 11 through the outlet 13.

[0027] In one embodiment, the telescopic end of the displacement control mechanism 7 is equipped with a mounting base 8, and the end of the corresponding crushing wheel 2 near the displacement control mechanism 7 is rotatably connected to the mounting base 8.

[0028] With this design, since the arc groove 3 is arc-shaped, the corresponding crushing wheel 2 will also move according to this shape when it moves in the arc groove 3. The setting of the mounting base 8 can prevent the displacement control mechanism 7 from getting stuck when driving the corresponding crushing wheel 2 to move, so as to facilitate actual operation.

[0029] In one embodiment, the transmission mechanism includes a motor 4 mounted on the crusher housing 1. The motor 4 drives another crushing wheel 2 that does not contact the arc groove 3 to rotate. A rotating column 5 is rotatably mounted on the inner wall of the crusher housing 1. The rotating column 5 is located at the center of the arc groove 3. Two transmission belt groups 6 are provided on the rotating column 5. The transmission belt group 6 consists of a first transmission wheel 61, a second transmission wheel 63, and a belt body 62 disposed on the two transmission wheels and drivingly engaging with them. A mounting bracket 64 is rotatably mounted on one of the crushing wheels 2. The first of the two transmission belt groups 6... All drive wheels 61 are coaxially mounted on the rotating column 5. The second drive wheel 63 in one of the drive belt groups 6 is coaxially mounted on another crushing wheel 2 driven by the motor 4. The second drive wheel 63 in the other drive belt group 6 is rotatably mounted on the mounting frame 64. The second drive wheel 63 and the corresponding crushing wheel 2 are coaxially mounted with meshing gears 65. Another arc-shaped groove 3 with the rotating column 5 as the center is opened on the inner wall of the crusher housing 1. The mounting frame 64 is equipped with a pin 66, which can be slidably inserted into the pin 66.

[0030] In specific implementation, when the displacement control mechanism 7 drives the corresponding crushing wheel 2 to approach or move away from the other crushing wheel 2 along the opening direction of the arc groove 3, since the rotating column 5 is located at the center of the arc groove 3, the distance between the two crushing wheels 2 and the rotating column 5 is constant. When the motor 4 is working, it drives the other crushing wheel 2 to rotate, and the corresponding transmission belt group 6 drives the rotating column 5 to rotate synchronously. During this process, the rotating column 5 will drive the other transmission belt group 6 to move, thereby causing the corresponding gear 65 to rotate and drive the other gear 65 located on the crushing wheel 2 to rotate, thus causing the corresponding crushing wheel 2 to rotate in the opposite direction, so that the rotational power can be transmitted to the corresponding crushing wheel 2 that can move on the arc groove 3. This method enables the two crushing wheels 2 to rotate effectively at different distances.

[0031] Understandably, the pin 66 will move in an arc shape in another arc groove 3 in sync with the mounting bracket 64, thus keeping the relative distance between the mounting bracket 64 and the crushing wheel 2 constant, so as to ensure that the two gears 65 can always remain in a meshed state.

[0032] In one embodiment, a downwardly inclined guide plate 9 is installed on the inner wall of the crusher housing 1, and the guide plate 9 is located at the top of both sides of the two crushing wheels 2.

[0033] With this design, the guide plate 9 is used to guide the ore into the middle between the two crushing wheels 2, so as to prevent the ore from affecting the transmission mechanism.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] Additionally, "multiple" refers to two or more.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
