Description

Technical Field

[0001] The present 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 for crushing large stones in industries such as mining, construction, and stone processing. As highly efficient crushing equipment, cone crushers are typically capable of handling materials of varying hardness, suitable for a variety of applications, including coarse, fine, and intermediate crushing. However, in practice, especially when crushing larger or harder stones, stone accumulation within the crushing chamber is a common problem. This can lead to reduced crushing efficiency, excessive equipment load, and even jamming or blockage. In severe cases, this can cause downtime or equipment damage.

[0003] For example, a blockage-proof cone crusher is disclosed in Chinese patent publication number CN118719197A. This device utilizes an eccentrically rotating crushing cone to avoid larger materials, and longitudinally adjusts the crushing cone to change the discharge gap between the limiting shell and the crushing cone to achieve the crushing of stones of different sizes and the anti-blocking effect. However, in actual use, although the device can improve the unobstructed discharge by adjusting the discharge gap, it cannot fundamentally eliminate the stone accumulation phenomenon, and an excessively wide discharge opening will reduce the crushing efficiency of the crusher. Furthermore, while the eccentric rotation of the crushing cone allows larger stones to pass through to solve the material jam problem, the stones that pass through are not effectively crushed and are transferred to the next stage. This only solves the material jam problem, but the stones are not effectively crushed, and the desired crushing effect cannot be achieved. Moreover, if the material jam occurs during the eccentric rotation process, 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.

[0014] A pretreatment method for a cone crusher for avoiding stone accumulation pretreatment is provided, and the method comprises the following steps:

[0015] S1: First, connect the guide barrel to the inlet of the cone crusher; then drive the external automatic feeding device to operate, and guide the stones into the first transfer bin through the automatic feeding device; and control the feeding amount of the external automatic feeding device to ensure that the stones in the first transfer bin are maintained in an appropriate amount of accumulation;

[0016] 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, so that they finally fall into the cone crusher;

[0017] S3: When the pressure sensor detects that the support pressure on the adjustment bin exceeds the threshold and lasts for a certain period of time, the rotary drive unit is activated to drive the first conduction bin to rotate. The rotating first conduction bin cooperates with the coiling plate fixed inside thereof 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, and thus solving the problem of material jamming.

[0019] The beneficial effects of the present invention compared with the prior art are as follows:

[0020] 1. Through the combination of the first conduction bin and the second conduction bin, the present invention forms a path capable of continuously conducting stones, and utilizes the function that the first conduction bin can be driven to rotate by the rotation drive unit to achieve dynamic adjustment of the stones during the conduction process, avoiding the problem of material jamming caused by excessive accumulation of stones.

[0021] 2. Through the coiling plate fixedly arranged in the first conduction bin, the present invention realizes how to lift and redistribute the stones accumulated in the first conduction bin in a short range, thereby reducing the pressure of the stones in the annular gap and effectively alleviating the problem of material jamming.

[0022] 3. The conical structure at the top of the adjustment bin of the present invention matches the inner wall of the conical bin, and the formed annular gap enables the discharged stones to be evenly scattered into the cone crusher, avoiding the excessive unilateral crushing pressure caused by traditional fixed-point feeding, and significantly improving the crushing uniformity and the stability of the equipment operation.

[0023] 4. The relative position between the adjustment bin and the second conduction bin of the present invention can be flexibly adjusted, and the width of the annular gap is precisely controlled through the first electric push rod, adapting to the pretreatment requirements of stones with different particle sizes, and enhancing the adaptability and practicability of the equipment.

[0024] 5. The present invention uses a pressure sensor to detect the bearing weight at the top of the adjustment bin in real time and is linked with an external automatic feeding device. When it detects that the pressure in the conduction bin exceeds the limit, it automatically adjusts the feeding speed or pauses the feeding to avoid the problem of material jamming that is likely to occur when overloading the conduction of stones.

[0040] To further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0041] See Figures 1 to 10As shown: A cone crusher for avoiding pre-treatment of stone accumulation, comprising: a housing 1; a movable guiding module 2, which is coaxially and fixedly arranged inside the housing 1 and is arranged near the upper end of the housing 1. The movable guiding module 2 is provided with a first conduction bin 21 capable of conducting stones and a rotation driving unit 22 capable of driving the first conduction bin 21 to rotate axially; a fixed guiding module 3, which is coaxially and fixedly arranged inside the housing 1 and is located below the movable guiding module 2. The fixed guiding module 3 is provided with a second conduction bin 31 capable of conducting stones; and the feeding port of the second conduction bin 31 is communicated with the discharging port of the first conduction bin 21; an adjusting module 4, which is coaxially and fixedly arranged inside the housing 1 and is arranged near the lower end of the housing 1; the adjusting module 4 is arranged below the fixed guiding module 3; the adjusting module 4 is provided with an adjusting bin 41 capable of longitudinally approaching or moving away from the discharging port of the second conduction bin 31; the top of the adjusting bin 41 matches the discharging port of the second conduction bin 31 and forms an annular gap capable of discharging stones with the second conduction bin 31; when the adjusting bin 41 longitudinally moves away from the second conduction bin 31, this annular gap becomes larger, and when the adjusting bin 41 longitudinally approaches the second conduction bin 31, this annular gap shrinks.

[0042] When pre-treatment of the stones to be crushed is required, first, the housing 1 is coaxially and fixedly arranged at the feeding port of the cone crusher. Subsequently, the external automatic feeding device is driven to start, and the stones are fed into the housing 1. At this time, the stones enter from the upper end of the housing 1, first enter the first conduction bin 21, and after passing through the first conduction bin 21, the stones are conducted into the second conduction bin 31 and finally enter the annular gap formed by the second conduction bin 31 and the adjusting bin 41. Through the annular gap, the stones finally enter the feeding port of the cone crusher.

[0043] When it is necessary to adjust the size of the conducted stones, only need to drive the adjusting bin 41 to act. The adjusting bin 41 moves axially, approaches or moves away from the second conduction bin 31, so as to change the width of the annular gap, and further adjust the size of the passing stones. This design can adapt to the passing requirements of stones with different diameters and provide a flexible function for adjusting the size of stones.

[0044] In addition, when the stones in the first conduction bin 21 and the second conduction bin 31 generate extrusion pressure due to accumulation, resulting in jamming of the stones entering the annular gap, only need to connect to an external power supply to drive the rotation driving unit 22 to start. The rotation driving unit 22 drives the first conduction bin 21 to rotate, so that the stones therein keep moving, change the original accumulation state, and avoid the occurrence of jamming. Through this mechanism, the stones can keep moving, thus effectively alleviating the jamming problem caused by accumulation and ensuring the smooth transmission of the stones into the crusher.

[0045] The introduction of a multi-bin conduction structure and adjustable annular gap effectively solves the problem of material jamming caused by stone accumulation, while also providing flexible adjustment of stone size. This ensures smooth flow of stone during the conduction process, improves crushing efficiency, and reduces equipment downtime and losses caused by material jamming.

[0046] See also Figure 7 and Figure 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 fixed 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 the annular gap between the second conducting chamber 31 and the regulating chamber 41 needs to be adjusted according to the diameter of the stone conveyed by the external automatic feeding equipment, the first electric push rod 44 can be operated according to the conduction requirements. Specifically, when the first electric push rod 44 is driven, its output shaft contracts, driving the regulating chamber 41 to move downward in the longitudinal direction away from the second conducting chamber 31, thereby increasing the annular gap and achieving a larger stone conducting gap. Conversely, when the output shaft of the first electric push rod 44 is extended, it drives the regulating chamber 41 to move upward in the longitudinal direction toward the second conducting chamber 31, thereby decreasing the annular gap and reducing the stone conducting gap.

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

[0049] A retaining ring 45, coaxially fixed to the bottom of the adjustment chamber 41, effectively prevents rocks from falling from the periphery of the adjustment chamber 41 into the cone crusher from contacting the first electric push rod 44 or the guide rod 43, thereby preventing damage to these critical components caused by rock impact. The retaining ring 45 protects the push rod and guide rod 43, extending the service life of the equipment and ensuring its safety and reliability.

[0050] See also Figure 7 and Figure 10 As shown: the adjustment module 4 also includes a pressure sensor 46 that can monitor the support pressure of the adjustment 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 adjustment chamber 41 through the pressure sensor 46.

[0051] By arranging a pressure sensor 46 at the driving end of the first electric push rod 44, the effect of real-time detection of the weight borne by the top of the adjustment bin 41 is achieved. Through the pressure sensor 46, the weight of the stone material borne by the top of the adjustment bin 41 can be sensed, and in cooperation with the automatic feeding equipment, the feeding amount can be dynamically adjusted according to the detection data. When the sensor detects that the bearing pressure at the top of the adjustment bin 41 is greater than the preset value, the detection signal will be transmitted 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 pressure of the stone material in the annular gap due to stone material accumulation. In addition, the real-time monitoring of the pressure sensor 46 can also provide data support for the entire feeding and crushing process, ensuring the stable operation of the equipment.

[0052] Through the linkage control of the pressure sensor 46 and the automatic feeding equipment, while realizing the dynamic adjustment of the stone material bearing, the problems of stone material accumulation and material jamming in the annular gap can be effectively avoided, improving the efficiency and stability of the feeding and crushing process, and at the same time reducing the maintenance cost and failure rate of the equipment.

[0053] See Figure 9 As shown: The second conduction bin 31 is composed of a conical bin 311 that is hollow and open at both ends and a guide cylinder 312 coaxially and fixedly arranged at the narrow end of the conical bin 311.

[0054] The first conduction bin 21 and the second conduction bin 31 are generally the same and are arranged oppositely, the difference being that a coiling plate 211 capable of coiling the stone material is provided in the first conduction bin 21.

[0055] The first conduction bin 21 and the second conduction bin 31 are arranged oppositely and the guide cylinders 312 respectively provided in the first conduction bin 21 and the second conduction bin 31 are coaxially connected. The outer diameter of the guide cylinder 312 in the first conduction bin 21 is set smaller than the inner diameter of the guide cylinder 312 in the second conduction bin 31, so that the guide cylinder 312 in the first conduction bin 21 is coaxially and slidably arranged in the guide cylinder 312 in the second conduction bin 31, thereby achieving the purpose of their connection; when the first conduction bin 21 rotates under the drive of a rotary drive, the guide cylinder 312 in the first conduction bin 21 and the guide cylinder 312 in the second conduction bin 31 are always in a connected state and do not affect each other.

[0056] See Figure 10 As shown: The adjustment bin 41 is composed of a conical part 411 and a guiding part 412 coaxially and fixedly arranged at the wide end of the conical part 411; and the outer wall of the conical part 411 matches the inner wall of the conical bin 311 and forms an annular gap with the conical bin 311 for the conduction and guiding of the stone material.

[0057] Since the top of the regulating 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 regulating bin 41 longitudinally closer to or away from the second conduction bin 31. Moreover, since the top of the regulating bin 41 is conical, the stones guided through the annular gap are evenly scattered in the circumferential direction into the cone crusher, and the materials are evenly dropped. 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 the stone is also obliquely arranged in the first conducting bin 21 , and multiple groups of the 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 stones being transferred inside to continue to move, thereby changing their original stacking position and significantly reducing the problem of material jamming caused by stone accumulation. However, since rotating the first transfer bin 21 by the rotary drive unit 22 alone can only change the horizontal position of the stones, in order to further reduce the stone transfer pressure within the annular gap, while the first transfer bin 21 is driven to rotate by the rotary drive unit 22, a coiling plate 211 fixedly mounted on the inner wall of the first transfer bin 21 is used to achieve a short-range lifting operation of the stones, giving them a larger range of movement 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 Figure 9 As shown: the rotation drive unit 22 includes a fixed base 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 base 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 bin 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 base 221 through the connecting frame 223; the driving gear 225 is coaxially fixedly arranged at the driving end of the servo motor 226 and engages with the driven gear 224 for rotation.

[0061] When the first conducting bin 21 needs to be rotated to keep the stones inside it moving, an external power source is first connected to activate the servo motor 226. The output shaft of the servo motor 226 rotates, driving the drive gear 225 fixed to its output shaft. The drive gear 225 transmits power through the meshing driven gear 224. The driven gear 224 then simultaneously drives the rotating frame on the fixed base 221 to rotate about its axis, ultimately driving the first conducting bin 21 to rotate along the axis of the material guide channel, thereby continuously moving the stones inside the first conducting bin 21, changing the conducting position, and preventing localized accumulation.

[0062] The cooperation between the servo motor 226 and the driving gear 225 realizes the continuous rotation drive of the first conduction bin 21, 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 in a vertical state on the outer wall of the second conduction bin 31 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 high 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 the stone needs to be further driven to move, it is only necessary to connect an external power supply to drive the second electric push rod to move. The output shaft of the second electric push rod will drive the rotary drive unit 22 to move synchronously in the retracted state, thereby prompting the first conduction bin 21 to axially approach the second conduction bin 31 and prompting the stone in the first conduction bin 21 to move upward. In this process, when the rotary drive unit 22 drives the first conduction bin 21 to rotate, the coiling plate 211 set on the inner wall of the first conduction bin 21 will further push the stone to form a winding motion, thereby achieving the effect of winding more stone from the bottom upward. In this way, not only can the pressure problem caused by stone accumulation in the annular gap be effectively reduced, but the material jamming phenomenon caused by static stone accumulation can also be significantly improved.

[0066] By driving the first conduction bin 21 to axially approach the second conduction bin 31 and cooperating with the rotary drive unit 22 to achieve the lifting operation of the stone material, it is possible to quickly adjust the position of the stone material when the conduction speed of the stone material is abnormal or there is material jamming, effectively reducing the accumulation pressure, ensuring the smooth conduction of the stone material, further improving the operation efficiency and crushing effect of the cone crusher, and at the same time reducing the possibility of shutdown for maintenance.

[0067] A preprocessing method for a cone crusher to avoid stone material accumulation, applying a cone crusher for avoiding stone material accumulation, comprising the following steps:

[0068] S1: First, connect the material guiding cylinder 312 to the feeding port of the cone crusher; then drive the external automatic feeding device to act, and introduce the stone material 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 material in the first conduction bin 21 maintains an appropriate accumulation state;

[0069] S2: At this time, the stone material falls into the annular gap under the action of gravity, and the regulating bin 41 disperses and guides the stone material, so that it finally falls 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, at this time, the rotary drive unit 22 acts to drive the first conduction bin 21 to rotate. The rotating first conduction bin 21 cooperates with the coiled material plate 211 fixedly arranged inside it to continuously lift the stone material by using the coiled material plate 211, thereby changing the current accumulation position and accumulation state of the stone material, thereby reducing the stone material conduction pressure in the annular gap, and thus solving the problem of material jamming;

[0071] S4: When S3 cannot solve the problem of material jamming, at this time, drive the linear reciprocating driver 23 to act, and longitudinally drive the regulating bin 41 away from the second conduction bin 31 through the linear reciprocating driver 23, and reset the linear reciprocating driver 23 after solving the material jamming problem.

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

[0073] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.

8. A pretreatment method for a cone crusher to avoid stone accumulation, which is applied to a cone crusher for avoiding stone accumulation pretreatment as described in claim 7, characterized in that, Comprising the following steps: S1: First, connect the material guiding cylinder (312) to the feeding port of the cone crusher; then drive the external automatic feeding device to act, and feed the stone material into the first conduction chamber (21) through the automatic feeding device; and control the feeding amount of the external automatic feeding device to ensure that the stone material in the first conduction chamber (21) maintains an appropriate accumulation state; S2: At this time, the stone material falls into the annular gap under the action of gravity, and the regulating chamber (41) disperses and guides the stone material, so that it finally falls into the cone crusher; S3: When the pressure sensor (46) detects that the support pressure on the regulating chamber (41) exceeds the threshold value and lasts for a certain period of time, drive the first conduction chamber (21) to rotate. The rotating first conduction chamber (21) cooperates with the coiled material plate (211) fixedly arranged inside it to continuously lift the stone material by using the coiled material plate (211), so as to change the current accumulation position and accumulation state of the stone material, thereby reducing the stone material conduction pressure in the annular gap and solving the problem of material jamming; S4: When S3 fails to solve the problem of material jamming, drive the first electric push rod (44) to act at this time, and longitudinally drive the regulating chamber (41) away from the second conduction chamber (31) through the first electric push rod (44), and reset the first electric push rod (44) after solving the material jamming problem.
