Detailed Description

The invention will be further described in detail with reference to the drawings and the detailed description below, in order to further understand the features and technical means of the invention and the specific objects and functions achieved.

Referring to fig. 1 to 10, a cone crusher for avoiding stone accumulation pretreatment includes a housing 1; the movable guide module 2 is coaxially and fixedly arranged in the shell 1 and is close to the upper end of the shell 1, and the movable guide module 2 is provided with a first conduction bin 21 capable of conducting stones and a rotary driving unit 22 capable of driving the first conduction bin 21 to axially rotate; the stone guide device comprises a shell 1, a fixed guide module 3, an adjusting module 4 and an adjusting module 4, wherein the fixed guide module 3 is coaxially and fixedly arranged in the shell 1 and is positioned below the movable guide module 2, the fixed guide module 3 is provided with a second guide bin 31 capable of conducting stone, a feed inlet of the second guide bin 31 is communicated with a discharge outlet of the first guide bin 21, the adjusting module 4 is coaxially and fixedly arranged in the shell 1 and is positioned near the lower end of the shell 1, the adjusting module 4 is arranged below the fixed guide module 3, the adjusting module 4 is provided with an adjusting bin 41 capable of longitudinally approaching or separating from the discharge outlet of the second guide bin 31, the top of the adjusting bin 41 is matched with the discharge outlet of the second guide bin 31, an annular gap capable of guiding stone is formed between the adjusting bin 41 and the second guide bin 31, and the annular gap is enlarged when the adjusting bin 41 is longitudinally separated from the second guide bin 31, and is reduced when the adjusting bin 41 longitudinally approaches the second guide bin 31.

When the stone to be crushed is required to be pretreated, the shell 1 is coaxially and fixedly arranged at the feed inlet of the cone crusher. The external automatic feeding device is then actuated to feed stone into the casing 1. At this time, stone enters from the upper end of the housing 1, first enters the first conduction bin 21, is conducted into the second conduction bin 31 after passing through the first conduction bin 21, and finally enters the annular gap formed by the second conduction bin 31 and the adjustment bin 41. Through the annular gap, the stone eventually enters the feed opening of the cone crusher.

When the size of the stone to be transmitted needs to be adjusted, the adjustment bin 41 is only required to be driven to act, and the adjustment bin 41 moves axially to be close to or far away from the second transmission bin 31, so that the width of the annular gap is changed, and the size of the stone passing through is adjusted. The design can adapt to the passing requirements of stones with different diameters, and provides flexible stone size adjusting function.

In addition, when the stones in the first conduction bin 21 and the second conduction bin 31 are accumulated to generate extrusion force, and the stones entering the annular gap are blocked, only an external power supply is connected to drive the rotary driving unit 22 to start. The rotary driving unit 22 drives the first conduction bin 21 to rotate, so that stones therein continuously move, the original stacking state is changed, and the occurrence of a blocking phenomenon is avoided. Through this mechanism, the building stones can keep moving to effectively alleviate the card material problem that leads to because of piling up, ensure that building stones are smoothly transmitted to the breaker in.

Through introducing many storehouses conducting structure and adjustable annular clearance, effectively solved the card material problem that the building stones accumulated and lead to, provided the nimble regulatory function to the building stones size simultaneously. Ensures the smooth flow of stones in the transmission process, improves the crushing efficiency, and reduces the equipment shutdown and loss caused by material clamping.

Referring to fig. 7 and 10, the adjusting module 4 further includes a first fixing frame 42, a guide rod 43 and a first electric push rod 44, wherein the first fixing frame 42 is coaxially and fixedly disposed in the housing 1 and is disposed near a discharge hole of the housing 1, the guide rod 43 is vertically disposed at the bottom of the adjusting bin 41, the rod portion of the guide rod 43 passes through the first fixing frame 42 and is in sliding fit with the first fixing frame 42, the first electric push rod 44 is vertically and fixedly disposed in the first fixing frame 42, and the driving end of the first electric push rod 44 is vertically disposed upwards and is fixedly connected with the adjusting bin 41.

When the size of the annular gap formed between the second conduction bin 31 and the adjustment bin 41 is correspondingly adjusted according to the diameter of stone conducted by the external automatic feeding equipment, the first electric push rod 44 is only required to be operated according to the conduction requirement. Specifically, when the first electric push rod 44 is driven to act, the output shaft of the first electric push rod is contracted, the adjusting bin 41 is driven to move downwards along the longitudinal direction and away from the second conducting bin 31, so that the annular gap is enlarged, and the effect of larger stone conducting gap is realized, whereas when the output shaft of the first electric push rod 44 extends, the adjusting bin 41 is driven to move upwards along the longitudinal direction and close to the second conducting bin 31, so that the annular gap is reduced, and the stone conducting gap is reduced.

Referring to fig. 10, a blocking ring 45 capable of blocking stones is coaxially and fixedly arranged at the bottom of the adjusting bin 41.

The ground blocking ring 45 is coaxially and fixedly arranged at the bottom of the adjusting bin 41, so that stones falling into the cone crusher from the periphery of the adjusting bin 41 can be effectively prevented from contacting the first electric push rod 44 or the guide rod 43, and damage to key parts caused by stone impact is avoided. The design of the material blocking ring 45 protects the push rod and the guide rod 43, prolongs the service life of equipment, and ensures the safety and reliability of the device.

Referring to fig. 7 and 10, the adjusting module 4 further includes a pressure sensor 46 capable of monitoring the supporting pressure of the adjusting bin 41 in real time, the pressure sensor 46 is fixedly disposed at the driving end of the first electric push rod 44, and the driving end of the first electric push rod 44 is fixedly connected with the adjusting bin 41 through the pressure sensor 46.

By arranging the pressure sensor 46 at the driving end of the first electric push rod 44, the effect of detecting the weight borne by the top of the adjusting bin 41 in real time is achieved. The weight of the stones carried by the top of the adjustment bin 41 can be sensed by the pressure sensor 46, and the automatic feeding equipment is matched, so that the feeding amount is dynamically adjusted according to the detection data. When the sensor detects that the top bearing pressure of the regulating bin 41 is greater than a preset value, a detection signal is transmitted to an external automatic feeding device, so that the feeding device is driven to suspend or stop feeding until the pressure value is restored to be within a set range, and the problem of material clamping caused by overlarge pressure of stones in the annular gap due to stone accumulation is effectively avoided. In addition, the real-time monitoring of the pressure sensor 46 also provides data support for the entire feeding and crushing process, ensuring stable operation of the apparatus.

Through the coordinated control of pressure sensor 46 and autoloading equipment, can effectively avoid building stones to pile up and block material problem in the annular clearance when realizing building stones bearing dynamic adjustment, improve the efficiency and the stability of pay-off and crushing process, reduced the maintenance cost and the fault rate of equipment simultaneously.

Referring to fig. 9, the second conducting chamber 31 is composed of a hollow conical chamber 311 with two open ends, and a guiding cylinder 312 coaxially and fixedly arranged at the narrow end of the conical chamber 311.

The first conduction bin 21 and the second conduction bin 31 are substantially identical and are disposed opposite to each other, wherein the difference is that a coil plate 211 capable of rolling up stones is disposed in the first conduction bin 21.

The first conduction bin 21 and the second conduction bin 31 are oppositely arranged, the guide barrels 312 respectively arranged in the first conduction bin 21 and the second conduction bin 31 are coaxially communicated, wherein the outer diameter of the guide barrel 312 in the first conduction bin 21 is smaller than the inner diameter of the guide barrel 312 in the second conduction bin 31, so that the guide barrel 312 in the first conduction bin 21 is coaxially and slidably arranged in the guide barrel 312 in the second conduction bin 31, the purpose of communication between the two is achieved, and when the first conduction bin 21 rotates under the drive of a rotary driver, the guide barrels 312 in the first conduction bin 21 and the guide barrel 312 in the second conduction bin 31 are always communicated and are not affected by each other.

Referring to fig. 10, the adjusting bin 41 is composed of a conical portion 411 and a guiding portion 412 coaxially and fixedly arranged at the wide end of the conical portion 411, and the outer wall of the conical portion 411 is matched with the inner wall of the conical bin 311 and forms an annular gap with the conical bin 311 for conducting and guiding stones.

The top of the adjusting bin 41 is in a conical shape and is matched with the inner wall of the conical bin 311, so that an annular gap capable of conducting and guiding stones is formed, when the conducting gap of the annular gap is required to be increased or decreased, the adjusting bin 41 is only required to be longitudinally close to or far away from the second conducting bin 31, and the top of the adjusting bin 41 is in a conical shape, so that stones guided by the annular gap uniformly scatter into the cone crusher in the circumferential direction, and the technical problems of high crushing pressure and blockage on one side caused by fixed-point blanking are avoided.

Referring to fig. 1 to 10, a material rolling plate 211 capable of rolling up stones is also obliquely arranged in the first conduction bin 21, and a plurality of groups of material rolling plates 211 are circumferentially arranged along the axis of the first conduction bin 21.

When the stone is continuously conducted through the first conducting bin 21 and the second conducting bin 31, the first conducting bin 21 is driven to rotate by the rotary driving unit 22, so that the stone which is internally conducted can be continuously moved, the original stacking position of the stone is changed, and the problem of material blockage caused by stone stacking is remarkably reduced. However, since only the first conduction bin 21 is rotated by the rotation driving unit 22 to change the horizontal position of the stone, in order to further reduce the stone conduction pressure in the annular gap, the first conduction bin 21 is driven to rotate by the rotation driving unit 22 and simultaneously is matched with the coil plate 211 fixedly arranged on the inner wall of the first conduction bin 21, so that the short-range coil-up operation of the stone can be realized, the stone has a larger movable stroke in the conduction process, the conduction pressure is effectively relieved, and the continuity and stability of stone conduction are improved.

Referring to fig. 6 and 9, the rotary driving unit 22 comprises a fixed seat 221, a rotary ring 222, a connecting frame 223, a driven gear 224, a driving gear 225 and a servo motor 226, wherein the rotary ring 222 is coaxially and rotatably arranged on the fixed seat 221, the connecting frame 223 is fixedly arranged on the rotary ring 222 and provided with a plurality of groups along the axis circumference of the rotary ring 222, the first conducting bin 21 is fixedly connected with the rotary ring 222 through a plurality of groups of connecting frames 223, the driven gear 224 is coaxially and fixedly arranged in the rotary ring 222, the servo motor 226 is fixedly arranged on the fixed seat 221 through the connecting frame 223, and the driving gear 225 is coaxially and fixedly arranged on the driving end of the servo motor 226 and meshed with the driven gear 224 for rotation.

When the first conduction bin 21 needs to be driven to rotate so as to enable the stones in the first conduction bin to continuously move, an external power supply is 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 on the output shaft of the servo motor to rotate. The driving gear 225 realizes power transmission through the driven gear 224 meshed with the driving gear, and the driven gear 224 drives the rotating frame to rotate around the axis of the rotating frame on the fixed seat 221 synchronously, so that the effect of driving the first conduction bin 21 to rotate along the axis of the material guiding channel is finally realized, and therefore stones in the first conduction bin 21 continuously move, change the conduction position and avoid partial accumulation.

Through the cooperation of servo motor 226 and drive gear 225, realized the continuous rotation drive to first conduction storehouse 21, make the building stones in it be in dynamic conduction state all the time, avoided static accumulations's possibility.

Referring to fig. 1 and 8, the movable guiding module 2 further includes a linear reciprocating driver 23 capable of driving the first conducting bin 21 and the rotary driving unit 22 to axially move along the axis of the housing 1, where the linear reciprocating driver 23 is fixedly disposed on the outer wall of the second conducting bin 31 in a vertical state through a second fixing frame 24, and an output shaft of the linear reciprocating driver is fixedly connected with the rotary driving unit 22.

The linear reciprocating driver 23 is specifically a second electric push rod.

When the pressure detected by the pressure sensor 46 is high during the process of conducting the stone through the first conducting bin 21 and the second conducting bin 31, which causes abnormal stone conduction speed or slow transmission, and the stone needs to be further driven to move, the second electric push rod is driven to move only by accessing an external power supply, and the output shaft of the second electric push rod drives the rotary driving unit 22 to synchronously move in a contracted state, so that the first conducting bin 21 is driven to be axially close to the second conducting bin 31, and the stone in the first conducting bin 21 is driven to move upwards. In this process, when the first conduction bin 21 is driven to rotate by the rotation driving unit 22, the rolling plate 211 disposed on the inner wall of the first conduction bin 21 further pushes the stone to form rolling motion, so as to achieve the effect of rolling more stone from bottom to top. By the mode, the problem of pressure caused by stone accumulation in the annular gap can be effectively reduced, and the phenomenon of material clamping caused by static accumulation of stones can be remarkably improved.

Through driving first conduction storehouse 21 and second conduction storehouse 31 axial to cooperate rotatory drive unit 22 to realize the operation of rising of rolling up to the building stones, can be when building stones conduction speed is unusual or card material quick adjustment building stones position, effectively alleviate and pile up pressure, ensure that the building stones are smooth and easy to be conducted, further improve cone crusher's operating efficiency and crushing effect, reduce the possibility of shutting down the maintenance simultaneously.
