Description

Technical Field

[0001] The invention relates to the technical field of cone crushers, and in particular to a cone crusher and a method for avoiding stone accumulation pretreatment. Background Art

[0002] Cone crushers are widely used in the crushing of large stones in industries such as mining, construction and stone processing. As an efficient crushing equipment, cone crushers can usually handle materials of different hardness and are suitable for a variety of working conditions such as coarse crushing, fine crushing and medium crushing. However, in actual use, especially when crushing larger or harder stones, the problem of stone accumulation in the crushing chamber often occurs, resulting in reduced crushing efficiency, excessive equipment load, and even stagnation or blockage, which may cause downtime or equipment damage in severe cases.

[0003] For example, a blocking-proof cone crusher is applied for with Chinese patent announcement number: CN118719197A. The device adopts an eccentrically rotatable crushing cone to avoid larger materials, and changes the discharge gap between the limit shell and the crushing cone by longitudinally adjusting the crushing cone to achieve the crushing of stones of different sizes and the blocking-proof effect. However, in actual use, although the discharge smoothness can be improved by adjusting the discharge gap, the stone accumulation phenomenon cannot be fundamentally eliminated, and the overly wide discharge port will reduce the crushing efficiency of the crusher. Furthermore, when the eccentrically rotating crushing cone is used to allow larger stones to pass through to solve the jamming problem, the passed stones are not effectively crushed and are transferred to the next stage, which only solves the jamming problem but the stones are not effectively crushed and the desired crushing effect cannot be achieved. Moreover, if the jamming phenomenon occurs during the eccentric rotation, the crushing cone will not only fail to complete the crushing operation, but may also further aggravate the blockage, affecting the continuity and reliability of the equipment operation.

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] See also Figures 1 to 10As shown: A cone crusher for avoiding stone accumulation pretreatment, comprising: a shell 1; a movable guide module 2, the movable guide module 2 is coaxially fixedly arranged in the shell 1 and arranged near the upper end of the shell 1, the movable guide module 2 is provided with a first conduction bin 21 capable of conducting stones and a rotation drive unit 22 capable of driving the first conduction bin 21 to rotate axially; a fixed guide module 3, the fixed guide module 3 is coaxially fixedly arranged in the shell 1 and located below the movable guide module 2, the fixed guide module 3 is provided with a second conduction bin 31 capable of conducting stones; and the feed port of the second conduction bin 31 is aligned with the feed port of the first conduction bin 21 is connected to the discharge port; an adjusting module 4, which is coaxially fixed in the shell body 1 and arranged near the lower end of the shell body 1; the adjusting module 4 is arranged below the fixed guiding module 3; the adjusting module 4 is provided with an adjusting bin 41 which can longitudinally approach or move away from the discharge port of the second conduction bin 31; the top of the adjusting bin 41 matches the discharge port of the second conduction bin 31, and forms an annular gap with the second conduction bin 31 for guiding the stone; when the adjusting bin 41 longitudinally moves away from the second conduction bin 31, the annular gap becomes larger, and when the adjusting bin 41 longitudinally approaches the second conduction bin 31, the annular gap becomes smaller.

[0042] When the stone to be crushed needs to be pre-processed, the shell 1 is first coaxially fixed at the feed port of the cone crusher. Then, the external automatic feeding device is driven to start and the stone is fed into the shell 1. At this time, the stone enters from the upper end of the shell 1, first enters the first conduction bin 21, and after passing through the first conduction bin 21, the stone is conducted to the second conduction bin 31, and finally enters the annular gap formed by the second conduction bin 31 and the adjustment bin 41. Through the annular gap, the stone finally enters the feed port of the cone crusher.

[0043] When the size of the stones to be conducted needs to be adjusted, the adjustment chamber 41 only needs to be driven to move axially, so that it is close to or away from the second conduction chamber 31, thereby changing the width of the annular gap and adjusting the size of the stones passing through. This design can meet the needs of stones of different diameters passing through and provide a flexible stone size adjustment function.

[0044] In addition, when the stones in the first conductive bin 21 and the second conductive bin 31 generate squeezing force due to accumulation, causing the stones entering the annular gap to get stuck, it is only necessary to connect an external power source to drive the rotary drive unit 22 to start. The rotary drive unit 22 drives the first conductive bin 21 to rotate, so that the stones therein continue to move, changing the original accumulation state and avoiding the occurrence of the jamming phenomenon. Through this mechanism, the stones can continue to move, thereby effectively alleviating the jamming problem caused by accumulation and ensuring that the stones are smoothly transmitted to the crusher.

[0045] By introducing a multi-bin conduction structure and an adjustable annular gap, the problem of material jamming caused by stone accumulation is effectively solved, while providing a flexible adjustment function for stone size. This ensures smooth flow of stone during the conduction process, improves crushing efficiency, and reduces equipment downtime and loss caused by material jamming.

[0046] See also Figure 7 and Fig.10 As shown: the adjustment module 4 also includes a first fixed frame 42, a guide rod 43 and a first electric push rod 44; the first fixed frame 42 is coaxially fixedly arranged in the shell 1 and is arranged near the discharge port of the shell 1; the guide rod 43 is vertically arranged at the bottom of the adjustment bin 41 and the rod portion of the guide rod 43 passes through the first fixed frame 42 and slides with the first fixed frame 42; the first electric push rod 44 is fixedly arranged in the first fixed frame 42 in a vertical state, and the driving end of the first electric push rod 44 is vertically arranged upward and fixedly connected to the adjustment bin 41.

[0047] When it is necessary to adjust the size of the annular gap formed between the second conduction bin 31 and the adjustment bin 41 according to the diameter of the stone conducted by the external automatic feeding device, it is only necessary to operate the first electric push rod 44 according to the conduction requirements. Specifically, when the first electric push rod 44 is driven to move, its output shaft contracts, and the adjustment bin 41 is driven to move downward in the longitudinal direction away from the second conduction bin 31, thereby increasing the annular gap and achieving the effect of a larger stone conduction gap; conversely, when the output shaft of the first electric push rod 44 is extended, the adjustment bin 41 is driven to move upward in the longitudinal direction close to the second conduction bin 31, thereby reducing the annular gap and reducing the stone conduction gap.

[0048] See also Fig.10 As shown, a blocking ring 45 capable of blocking stones is coaxially fixedly arranged at the bottom of the regulating bin 41.

[0049] The material blocking ring 45 coaxially fixedly arranged at the bottom of the adjusting bin 41 can effectively prevent the stones falling from the periphery of the adjusting bin 41 into the cone crusher from contacting the first electric push rod 44 or the guide rod 43, thereby avoiding damage to these key components caused by the impact of the stones. The design of the material blocking ring 45 protects the push rod and the guide rod 43, prolongs the service life of the equipment, and ensures the safety and reliability of the device.

[0050] See also Figure 7 and Fig.10 As shown: the regulating module 4 also includes a pressure sensor 46 that can monitor the supporting pressure of the regulating chamber 41 in real time; the pressure sensor 46 is fixedly arranged at the driving end of the first electric push rod 44; the driving end of the first electric push rod 44 is fixedly connected to the regulating chamber 41 through the pressure sensor 46.

[0051] By setting a pressure sensor 46 at the driving end of the first electric push rod 44, the effect of real-time detection of the weight carried on the top of the regulating bin 41 is achieved. The pressure sensor 46 can sense the weight of the stone carried on the top of the regulating bin 41, and cooperate with the automatic feeding equipment to dynamically adjust the feeding amount according to the detection data. When the sensor detects that the bearing pressure on the top of the regulating bin 41 is greater than the preset value, it will transmit the detection signal to the external automatic feeding equipment, driving the feeding equipment to suspend or stop feeding until the pressure value returns to the set range, thereby effectively avoiding the problem of material jamming caused by excessive stone pressure in the annular gap due to stone accumulation. In addition, the real-time monitoring of the pressure sensor 46 can also provide data support for the entire feeding and crushing process to ensure stable operation of the equipment.

[0052] Through the linkage control of the pressure sensor 46 and the automatic feeding equipment, it is possible to effectively avoid stone accumulation and jamming problems in the annular gap while achieving dynamic adjustment of the stone load, thereby improving the efficiency and stability of the feeding and crushing process and reducing the maintenance cost and failure rate of the equipment.

[0053] See also Fig. 9 As shown, the second conducting bin 31 is composed of a conical bin 311 which is hollow and open at both ends, and a material guide cylinder 312 which is coaxially fixedly arranged at the narrow end of the conical bin 311 .

[0054] The first conducting bin 21 and the second conducting bin 31 are substantially the same and are arranged opposite to each other, wherein the difference is that a coiling plate 211 capable of rolling up stones is disposed in the first conducting bin 21 .

[0055] The first conduction bin 21 and the second conduction bin 31 are arranged opposite to each other, and the material guide cylinders 312 respectively arranged in the first conduction bin 21 and the second conduction bin 31 are coaxially connected, wherein the outer diameter of the material guide cylinder 312 in the first conduction bin 21 is smaller than the inner diameter of the material guide cylinder 312 in the second conduction bin 31, so that the material guide cylinder 312 in the first conduction bin 21 is coaxially slidably arranged in the material guide cylinder 312 in the second conduction bin 31, thereby achieving the purpose of connecting the two; when the first conduction bin 21 rotates under the drive of the rotary drive, the material guide cylinder 312 in the first conduction bin 21 and the material guide cylinder 312 in the second conduction bin 31 are always connected and do not affect each other.

[0056] See also Fig.10 As shown: the regulating bin 41 is composed of a conical portion 411 and a guide portion 412 coaxially fixedly arranged at the wide end of the conical portion 411; and the outer wall of the conical portion 411 matches the inner wall of the conical bin 311, and forms an annular gap with the conical bin 311 for conducting and guiding stones.

[0057] Since the top of the adjusting bin 41 is conical and matches the inner wall of the conical bin 311, an annular gap is formed to conduct and guide the stones. When the conduction gap of the annular gap needs to be increased or decreased, it is only necessary to drive the adjusting bin 41 longitudinally close to or away from the second conduction bin 31. Moreover, since the top of the adjusting bin 41 is conical, the stones guided by the annular gap are evenly scattered in the circumferential direction into the cone crusher, and the materials are evenly dropped, and there will be no technical problems such as high crushing pressure on one side and material jamming due to fixed-point dropping.

[0058] See also Figures 1 to 10 As shown, a coiling plate 211 capable of rolling up stones is obliquely arranged in the first conducting bin 21 , and a plurality of coiling plates 211 are arranged circumferentially along the axis of the first conducting bin 21 .

[0059] When the stones are continuously transferred through the first transfer bin 21 and the second transfer bin 31, the first transfer bin 21 is driven to rotate by the rotary drive unit 22, which can cause the internally transferred stones to continuously move, thereby changing their original stacking position and significantly reducing the material jamming problem caused by stone accumulation. However, since rotating the first transfer bin 21 only by the rotary drive unit 22 can only change the horizontal position of the stones, in order to further reduce the stone transfer pressure in the annular gap, while the first transfer bin 21 is driven to rotate by the rotary drive unit 22, the material coiling plate 211 fixedly arranged on the inner wall of the first transfer bin 21 can be used to achieve a short-range rolling operation of the stones, so that the stones have a larger active stroke during the transfer process, thereby effectively alleviating the transfer pressure and improving the continuity and stability of the stone transfer.

[0060] See also Figure 6 and Fig. 9 As shown: the rotation drive unit 22 includes a fixed seat 221, a rotating ring 222, a connecting frame 223, a driven gear 224, a driving gear 225 and a servo motor 226; the rotating ring 222 is coaxially rotatably arranged on the fixed seat 221; the connecting frame 223 is fixedly arranged on the rotating ring 222 and multiple groups are arranged circumferentially along the axis of the rotating ring 222; the first conduction chamber 21 is fixedly connected to the rotating ring 222 through multiple groups of connecting frames 223; the driven gear 224 is coaxially fixedly arranged in the rotating ring 222; the servo motor 226 is fixedly arranged on the fixed seat 221 through the connecting frame 223; the driving gear 225 is coaxially fixedly arranged at the driving end of the servo motor 226 and meshes and rotates with the driven gear 224.

[0061] When the first conducting bin 21 needs to be driven to rotate so that the stones inside it can be continuously moved, an external power source is first connected to drive the servo motor 226 to start, and the output shaft of the servo motor 226 rotates to drive the driving gear 225 fixed to its output shaft to rotate. The driving gear 225 realizes power transmission through the driven gear 224 meshing with it, and the driven gear 224 synchronously drives the rotating frame to rotate around its axis on the fixed seat 221, and finally realizes the effect of driving the first conducting bin 21 to rotate along the axis of the material guide channel, so that the stones in the first conducting bin 21 can be continuously moved, the conducting position can be changed, and local accumulation can be avoided.

[0062] Through the cooperation of the servo motor 226 and the driving gear 225, the first conduction bin 21 is driven to rotate continuously, so that the stones inside are always in a dynamic conduction state, avoiding the possibility of static accumulation.

[0063] See also Figure 1 and Figure 8 As shown: the movable guiding module 2 also includes a linear reciprocating drive 23 capable of driving the first conduction bin 21 and the rotation drive unit 22 to move axially along the axis of the shell 1; the linear reciprocating drive 23 is fixedly arranged on the outer wall of the second conduction bin 31 in a vertical state through a second fixed frame 24, and the output shaft of the linear reciprocating drive is fixedly connected to the rotation drive unit 22.

[0064] The linear reciprocating drive 23 is specifically a second electric push rod.

[0065] When the pressure detected by the pressure sensor 46 is relatively large during the process of conducting the stone through the first conduction bin 21 and the second conduction bin 31, resulting in abnormal conduction speed or slow transmission of the stone, and when it is necessary to further drive the stone to move, it is only necessary to connect an external power supply to drive the second electric push rod to move, and the output shaft of the second electric push rod will drive the rotation drive unit 22 to move synchronously in the contracted state, thereby prompting the first conduction bin 21 to be axially close to the second conduction bin 31, and prompting the stone in the first conduction bin 21 to move upward. In this process, when the first conduction bin 21 is driven to rotate in cooperation with the rotation drive unit 22, the coiling plate 211 provided on the inner wall of the first conduction bin 21 will further push the stone to form a rolling motion, thereby achieving the effect of rolling more stone from the bottom to the top. In this way, not only can the pressure problem caused by the accumulation of stones in the annular gap be effectively reduced, but also the jamming phenomenon caused by the static accumulation of stones can be significantly improved.

[0066] By driving the first conduction bin 21 and the second conduction bin 31 axially close together and cooperating with the rotary drive unit 22 to realize the stone lifting operation, the stone position can be quickly adjusted when the stone conduction speed is abnormal or the material is stuck, effectively reducing the stacking pressure, ensuring smooth stone conduction, further improving the operating efficiency and crushing effect of the cone crusher, and reducing the possibility of shutdown for maintenance.

[0067] A pretreatment method for a cone crusher for avoiding stone accumulation pretreatment, using a cone crusher for avoiding stone accumulation pretreatment, comprising the following steps:

[0068] S1: First, connect the guide cylinder 312 with the feed port of the cone crusher; then drive the external automatic feeding device to operate, and guide the stones into the first conduction bin 21 through the automatic feeding device; and control the feeding amount of the external automatic feeding device to ensure that the stones in the first conduction bin 21 are maintained in an appropriate amount of accumulation state;

[0069] S2: At this time, the stones fall into the annular gap under the action of gravity, and are dispersed and guided by the regulating bin 41, so that they finally fall into the cone crusher;

[0070] S3: When the pressure sensor 46 detects that the support pressure on the regulating bin 41 exceeds the threshold value and lasts for a certain period of time, the rotary drive unit 22 is actuated to drive the first conduction bin 21 to rotate. The rotating first conduction bin 21 cooperates with the coiling plate 211 fixed inside thereof to continuously roll up the stone, thereby changing the current stacking position and stacking state of the stone, thereby reducing the conduction pressure of the stone in the annular gap, thereby solving the problem of material jamming.

[0071] S4: When S3 cannot solve the material jamming problem, the linear reciprocating drive 23 is driven to operate, and the adjustment bin 41 is longitudinally driven away from the second conduction bin 31 by the linear reciprocating drive 23, and the linear reciprocating drive 23 is reset after solving the material jamming problem.

[0072] The present invention can not only monitor the conduction state of the stone in real time but also can self-adjust the conduction mode when the stone is stuck, and has high conduction efficiency and good effect.

[0073] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.

10. A pretreatment method for a cone crusher to avoid stone accumulation pretreatment, applied to a cone crusher to avoid stone accumulation pretreatment as claimed in any one of claims 1 to 9, comprising the following steps: S1: First, connect the guide cylinder (312) to the feed port of the cone crusher; then drive the external automatic feeding device to operate, and guide the stone into the first conduction bin (21) through the automatic feeding device; and control the feeding amount of the external automatic feeding device to ensure that the stone in the first conduction bin (21) is maintained in a proper amount of accumulation state; S2: At this time, the stones fall into the annular gap under the action of gravity, and are dispersed and guided by the regulating bin (41) so that they finally fall into the cone crusher; S3: When the pressure sensor (46) detects that the support pressure on the regulating bin (41) exceeds a threshold value and lasts for a certain period of time, the first conducting bin (21) is driven to rotate, and the rotating first conducting bin (21) cooperates with the coiling plate (211) fixed inside the first conducting bin (21) to continuously roll up the stone, thereby changing the current stacking position and stacking state of the stone, thereby reducing the stone conduction pressure in the annular gap, thereby solving the problem of material jamming; S4: When S3 cannot solve the material jamming problem, the linear reciprocating drive (23) is driven to operate, and the adjustment bin (41) is longitudinally driven away from the second conduction bin (31) by the linear reciprocating drive (23), and the linear reciprocating drive (23) is reset after the material jamming problem is solved.
