Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 and 2, the present application discloses a mineral separator 100 comprising:
a feeding mechanism 11 for feeding ore;
a transport mechanism 12 for transporting the ore to a predetermined position after loading the ore from the feed mechanism 11;
a detection mechanism 13 for detecting the ore at a predetermined position;
the sorting mechanism 14 is used for sorting and picking up the detection result of the ore according to the detection mechanism 13;
wherein the transport mechanism 12 comprises a transport belt 122; a driving roller 123 for driving the transmission belt 122 to move; a driven roller 124 which cooperates with the driving roller 123 to circulate the conveying belt 122; and a belt deviation correcting device 125 disposed between the driving roller 123 and the driven roller 124.
The mineral separator 100 may have various shapes, and may be represented as a metal mineral separator 100 or a nonmetal mineral separator 100 in a specific scene. A metal mineral separator 100 such as iron ore, copper ore, antimony ore, and various rare earth metal ores, etc. A non-metallic mineral separator 100, such as a diamond ore, coal mine, or the like. The mineral separator 100 functions to separate mineral products rich in elements to be extracted from slag that is poor in the elements to be extracted. The mineral separator 100 screens out minerals rich in the elements to be extracted for further processing to form material data beneficial to human beings.
A feeding mechanism 11 for feeding ore. The ore supplied by the feeding mechanism 11 may be a primary raw material or a raw material that has been previously processed. The primary raw material can be obtained directly from the mine by crushing or cutting. The raw material for the rough treatment may be obtained from the primary raw material by simple particle size screening, for example, by removing ores with too large and too small diameters to obtain ores with a particle size within a certain range. Specifically, the feeding mechanism 11 may be provided with a restriction tank, a funnel tank, a vibrating screen, a classifying screen, and the like to obtain ore materials according with expectations. It is understood that the specific form of the feeding mechanism 11 herein obviously does not constitute a limitation to the specific protection scope of the present application.
And a transport mechanism 12 for transporting the ore to a predetermined position after loading the ore from the feeding mechanism 11. It will be appreciated that the transport mechanism 12 has a location to load ore. The position of the ore in the device can be understood as the initial position of the ore on the transport means 12. The setting of the ore loading position is related to the specific configuration of the conveying mechanism 12 and the feeding mechanism 11.
In one practical embodiment provided herein, the feeding mechanism 11 may be a hopper trough, the transport mechanism 12 transports ore through the conveyor belt 122, and the location where ore is loaded may be a location below the hopper trough that is directly opposite the conveyor belt 122. The predetermined position may be understood as a point along which the path of ore transport must pass or a position along which the path must pass. In addition, the transmission mechanism 12 is further provided with a driving roller 123 for driving the transmission belt 122 to move, and a driven roller 124 for realizing the circulation of the transmission belt 122 in cooperation with the driving roller 123. Thus, the conveying belt 122 is unfolded to move circularly by the driving roller 123 and the driven roller 124. In the design concept of the mineral separator 100, the predetermined position is used for judging the mineral or ore rich in the element to be extracted and the slag or ore poor in the element to be extracted for subsequent processing. It is worth noting that the ore falls into the conveyer belt and can produce certain impact force, and under the effect of impact force, the ore can jump relative to the conveyer belt and can not stably fall on the conveyer belt. The conveyor 12 may therefore also be provided with a buffer device 121 to buffer the run-out of ore on the conveyor. In this way, the ore only moves in the direction of transport, or in other words, the ore remains stationary relative to the transport mechanism 12 at the predetermined location, and there is no movement relative to the ore transport assembly in the direction of gravity. That is, the conveyor belt 122 moves the ore to a predetermined position at a moving speed that is consistent with the speed of the conveyor belt 122 under the action of the driving roller 123 and the driven roller 124. In this way, the ore can move in a relatively simple state at the predetermined position, which is beneficial for the ore sorter 100 to judge the ore.
And the detection mechanism 13 is used for detecting the ore at a preset position. In an implementable embodiment provided by the present application, mineral products rich in the element to be extracted are separated from slag poor in the element to be extracted using optical means. The detection mechanism 13 may use X-rays. The detection mechanism 13 may include an X-ray generation device and an X-ray detection device. The X-ray detection device can determine the enrichment degree of the elements to be extracted through optical phenomena such as transmission, diffraction and spectrum of X-rays, so that the separation of ores is carried out. It will be appreciated that the detection mechanism 13 herein may be loaded with different identification or analysis models depending on the ore type to improve the efficiency and accuracy of ore sorting. For example, loading a recognition model for rare earth elements, loading a recognition model for coal mines or loading recognition models for different particle size ores, loading recognition models for different element enrichment concentrations.
And the sorting mechanism 14 is used for sorting and picking up the detection result of the ore according to the detection mechanism 13. The function of the sorting mechanism 14 is to separate the identified mineral products that are rich in the element to be extracted from the slag that is poor in the element to be extracted. Wherein the sorting mechanism 14 comprises a spraying device having at least two different fluid spraying modes for separating ore into at least three types.
In an implementation provided herein, the sorting mechanism 14 includes an air jet device, a liquid jet device, or a robot. The ore continues to move after the transport mechanism 12 passes the predetermined position and eventually disengages from the transport mechanism 12. The sorting mechanism 14 may sort and pick the identified ore before or during the detachment of the ore from the conveyor mechanism 12. For example, the flight path of ore as it exits from the conveyor 12, and thus the drop point of ore, may be varied by means of a jet device during the exit of ore from the conveyor 12. It can be understood that the gas injection device can realize the separation of ores meeting the conditions only by configuring compressed gas, and the realization cost is low. For another example, the flight path of the ore when the ore is separated from the conveying mechanism 12 can be changed by the liquid spraying device in the separation process of the ore from the conveying mechanism 12, and the falling point of the ore can be further changed. It can be understood that the liquid spraying device needs to be provided with pressure liquid, and although the realization cost is high, the ore can be cleaned, and the convenience is brought to the subsequent treatment of the ore. As another example, a robot may be used to pick up ore that meets the conditions before it is detached from the conveyor mechanism 12. It will be appreciated that whilst it is costly to pick up ore satisfying the conditions using a robot, the use of a refined classification of the ore may facilitate subsequent processing of the ore.
It should be noted that, in an actual application scenario, due to the precision problem of the processing and installation of the conveyor belt 122, during the operation of the conveying mechanism 12 of the mineral sorting machine 100, the conveyor belt 122 may deviate, specifically, the conveyor belt 122 may move in a direction perpendicular to the original operation direction of the conveyor belt 122. When the conveyor belt 122 deviates, the ore on the conveyor belt cannot be separated from the conveyor belt 122 according to the predetermined movement track, i.e. deviates from the original predetermined separation position, and is not in the separation range of the separation mechanism 14. In this way, the sorting mechanism 14 cannot accurately sort the materials, thereby affecting ore sorting accuracy. Therefore, the conveying mechanism 12 further includes a conveying belt deviation correcting device 125 disposed between the driving roller 123 and the driven roller 124 to correct the real-time running direction of the conveying belt 122 when the conveying belt 122 deviates, and ensure that ore can be stably conveyed to a predetermined deviation position and be deviated from the conveying belt 122 in a predetermined trajectory.
Further, in a preferred embodiment provided herein, the conveyor belt deviation rectifying device 125 includes: the conveying belt detection device 1251 is configured to send a deviation rectification control signal when an included angle between the running direction of the conveying belt 122 and a preset direction is detected; a deviation rectification motor 1252 for operating upon receiving the deviation rectification control signal; and the deviation rectifying combination 1253 is driven by the deviation rectifying motor 1252 to reset the conveying belt 122.
It will be appreciated that the conveyor belt 122 is driven by the drive roller 123 to move in a spread motion and, under the action of the driven roller 124, to move in a loop motion. The conveyor belt 122 operates normally according to a predetermined operation, and drives the ore to a predetermined separation position at a predetermined speed, and is classified by the sorting mechanism 14 in a predetermined sorting manner. However, since there is a certain error in the processing and installation of the conveyor belt 122, the conveyor belt deviates from the preset direction in the operation process, and thus the moving direction of the ore is changed, and the ore cannot be transported to the designated sorting area. In practical application, the outer ring of the transmission mechanism 12 is usually provided with a safety isolation device for preventing workers from accidentally injuring due to ore splashing, so that the workers cannot find the deviation of the transmission belt 122 at the first time. When the conveyor mechanism 12 is found to be running abnormally and the running direction of the conveyor belt 122 is readjusted, the sorted ore often needs to be sorted again, which undoubtedly reduces the efficiency of ore sorting. Therefore, it is necessary to provide a belt detecting device 1251 for detecting the moving direction of the belt 122 in the belt deviation correcting device 125. The conveying belt detecting device 1251 can detect the running direction of the conveying belt 122 by using a distance sensing method or a light detecting method.
When the conveying belt detection device 1251 detects that the running direction of the conveying belt 122 is deviated from the original preset direction, a running abnormal signal can be sent out immediately, so that the running direction of the conveying belt 122 can be adjusted immediately. That is, when the conveying belt detecting device 1251 detects the deviation of the conveying belt 122, it immediately sends out a deviation-correcting control signal. It should be noted that the running direction of the conveyor 122 here deviates from the original preset direction, i.e. there is an included angle between the running direction of the conveyor 122 and the preset direction. It can be understood that, when the conveying belt 122 is not off tracking, the included angle between the running direction of the conveying belt 122 and the preset direction is 0. Therefore, the included angle between the running direction of the conveying belt 122 and the preset direction is a value other than 0. The deviation rectifying control signal can be sent to an equipment maintenance end for exception warning. When the worker finds the abnormal warning information, the operation of the mineral product sorter 100 can be suspended, and the tensioning adjustment of the conveyor belt 122 is performed. In this way, the worker can know in time that the transport mechanism 12 is abnormally operated. However, the manual adjustment of the running direction of the conveying belt 122 undoubtedly increases the manpower input, and in the manual deviation rectifying process of the conveying belt 122, the mineral product sorting machine 100 can not be put into actual production, and undoubtedly reduces the production efficiency. In addition, although the deviation of the conveying belt 122 can be limited by arranging a plurality of vertical rollers with cylindrical shapes on the two sides of the conveying belt 122, the vertical rollers can only limit the deviation of the conveying belt 122 within a certain range, and cannot automatically correct the deviation of the conveying belt 122 and enable the conveying belt to return to a preset position, and the maintenance of the conveying mechanism 12 still needs to be manually carried out. Therefore, the tensioning adjustment signal can also be sent to the automatic conveyor belt deviation correction mechanism. When the running direction of the conveying belt 122 is detected to be abnormal, the automatic deviation rectifying mechanism of the conveying belt 122 can reach the running direction of the conveying belt 122, and the working efficiency of the mineral product sorting machine 100 is guaranteed.
Specifically, when the deviation rectifying control signal is obtained by the automatic deviation rectifying mechanism of the conveyor belt 122, the automatic deviation rectifying mechanism of the conveyor belt 122 can spread out the deviation rectifying of the conveyor belt 122. That is, a force opposite to the offset direction is applied to the conveying belt 122 to gradually return the conveying belt 122 to the original running direction, i.e., to return to the original position. It will be appreciated that the motor is capable of converting electrical energy into mechanical energy and, via the motor shaft, moves the device to which it is connected in a predetermined manner. Therefore, a motor is preferred here as a power source of the tension automatic adjusting mechanism. After the deviation rectifying motor 1252 receives the deviation rectifying control signal, the deviation rectifying assembly 1253 connected to the deviation rectifying motor 1252 and used for adjusting the running direction of the conveyor 122 can be driven according to a preset deviation rectifying mode until the conveyor 122 resets.
It should be noted that the position at which the belt 122 starts to shift varies among the different transport mechanisms 12, and therefore, the belt deviation correcting device 125 may be installed at different positions. For example, the conveyor belt deviation correcting device 125 is installed at a position where the conveyor belt 122 receives ore from the feeding mechanism 11, and at several positions on the way of the conveyor belt 122 running the sorting mechanism 14. Thus, the deviation of the conveying belt 122 can be found at the first time, and the adjustment of the running direction of the conveying belt 122 can be timely carried out through the deviation rectifying motor 1252 and the deviation rectifying combination 1253.
Further, in a preferred embodiment provided herein, the rectification combination 1253 includes: a leveling roller 12531 abutting the conveyor belt 122; a mounting base 12532 for mounting the rectifying roller 12531; a push rod for driving the rectifying roller 12531 to rotate relative to the mounting base 12532.
It will be appreciated that the deskew assembly 1253 deskews the conveyor 122, primarily by applying a force to the conveyor 122 in a direction opposite to the direction of its offset. Therefore, the rectification assembly 1253 is provided with the rectification roller 12531 directly contacting the conveyor belt 122 and the mounting base 12532 mounting the rectification roller 12531. In addition, in order to ensure stable operation of the rectifying rollers 12531, the mount 12532 needs to be fixed to the mineral separator 100. When the conveying belt 122 is not deviated, the deviation rectifying roller 12531 is driven by the conveying belt 122 to rotate at a certain rotation speed. When the conveying belt 122 is shifted in a certain direction, a force opposite to the shifting direction is applied to the conveying belt 122, so that the running state of the conveying belt 122 can be changed.
Specifically, a force opposite to the offset direction is applied to the conveying belt 122, mainly by adjusting the orientation of the rectification roller 12531 relative to the conveying belt 122, that is, adjusting the real-time orientation of the rectification roller 12531 by the rectification motor 1252. The real-time orientation of the rectification roller 12531 is adjusted by the rectification motor 1252, and the rectification roller 12531 is driven by the rectification motor 1252 to rotate relative to the mounting seat 12532, or the rectification roller 12531 is driven by the rectification motor 1252 to translate relative to the mounting seat 12532.
The deflection correcting roller 12531 is driven by the deflection correcting motor 1252 to rotate relative to the mounting base 12532 by means of a push rod connected to the deflection correcting motor 1252. The pushing rod can drive the deviation rectifying roller 12531 to rotate in a direction opposite to the deviation direction of the conveying belt 122 according to a preset mode under the driving of the deviation rectifying motor 1252. Here, the mounting seat 12532 reserves a certain space for the rotation of the rectification roller 12531. The push rods are preferably symmetrically disposed at both ends of the rectification roller 12531. Namely, two sets of push rods are symmetrically arranged at two ends of the rectification roller 12531 respectively. In practical application, a lead screw or a hydraulic rod can be selected as the push rod according to actual conditions.
During the rotation of the rectification roller 12531, the rectification roller 12531 constantly applies a force to the transport belt 122 in a direction opposite to the offset direction thereof. Under the action of the force, the conveying belt 122 is brought back to the preset running path by the rectifying rollers 12531. In this way, the conveyor belt 122 continues to convey the ore on the original predetermined path, and prevents the ore from being separated from the conveyor mechanism 12 beyond the predetermined separation position.
Further, in a preferred embodiment provided herein, the rectification combination 1253 includes: a leveling roller 12531 abutting the conveyor belt 122; a mounting base 12532 for mounting the rectifying roller 12531; the deviation rectifying rollers 12531 are driven by the deviation rectifying motor 1252 to move laterally with respect to the running direction of the conveyor belt 122.
It will be appreciated that the deflection correcting assembly 1253 primarily adjusts the direction of travel of the conveyor 122 by controlling the orientation of the deflection correcting rollers 12531 relative to the conveyor 122. The real-time orientation of the rectification roller 12531 is adjusted by the rectification motor 1252, and the rectification roller 12531 is driven by the rectification motor 1252 to rotate relative to the mounting seat 12532, or the rectification roller 12531 is driven by the rectification motor 1252 to translate relative to the mounting seat 12532. The rectification roller 12531 is driven by the rectification motor 1252 to translate relative to the mounting base 12532, that is, the rectification roller 12531 moves towards the extending direction of the roller shaft of the rectification roller 12531 under the driving of the rectification motor 1252. The specific direction in which the rectification roller 12531 translates here is determined by the offset direction of the conveyor belt 122. For example, when the conveying belt 122 is shifted to the left in the preset direction, the deviation rectifying roller 12531 is driven by the deviation rectifying motor 1252 to move toward the right extending direction of the roller shaft of the deviation rectifying roller 12531, i.e., to traverse to the right with respect to the preset running direction of the conveying belt 122. When the conveying belt 122 is shifted to the right in the preset direction, the deviation rectifying roller 12531 is driven by the deviation rectifying motor 1252 to move towards the left extending direction of the roller shaft of the deviation rectifying roller 12531, i.e. to move transversely to the left of the preset running direction of the conveying belt 122. During the lateral movement of the deviation rectifying roller 12531 relative to the conveying belt 122, the conveying belt 122 can be brought back to the original running path. In this way, the conveyor belt 122 continues to convey the ore on the original predetermined path, and prevents the ore from being separated from the conveyor mechanism 12 beyond the predetermined separation position.
Further, in a preferred embodiment provided herein, the rectification roller 12531 continuously traverses with respect to the mounting seat 12532.
It will be appreciated that the leveling rollers 12531 translate relative to the direction of travel of the conveyor belt 122, i.e., the leveling rollers 12531 translate relative to the mounts 12532. Here, the continuous traverse, i.e., the correction roller 12531 is kept in lateral translation by the driving of the correction motor 1252, until the conveying belt 122 resumes running on the original moving path. Thus, the adjustment of the running offset of the conveying belt 122 can be continuously carried out, and the deviation rectifying efficiency of the conveying belt 122 is improved.
Further, in a preferred embodiment provided herein, a motor shaft of the deviation rectifying motor 1252 is coupled to the deviation rectifying roller 12531 through a worm gear and a worm.
The worm drives the worm wheel to rotate continuously at a certain rotation speed under the driving of the deviation rectifying motor 1252, so as to drive the deviation rectifying roller 12531 to move continuously and transversely relative to the mounting base 12532. Moreover, the rotation direction of the motor shaft is controlled by the deviation rectifying motor 1252, so that the rotation direction of the worm wheel can be controlled, and the deviation rectifying roller 12531 can translate towards different directions relative to the conveying belt 122. The motor shaft of the deviation correction motor 1252 is coupled to the worm to drive the worm gear to rotate in a predetermined manner. The rotation of the worm gear will drive the deviation rectifying roller 12531 coupled with the worm gear to transversely translate. The deviation correcting roller 12531 and the deviation correcting motor 1252 are matched and connected in a matching mode of worm and gear, so that a large speed ratio can be achieved by using a small overall dimension of the worm and gear, the occupied space of the deviation correcting motor 1252 and a transmission mechanism is saved, and the miniaturization of equipment is facilitated; and when the deviation rectifying motor 1252 drives the deviation rectifying roller 12531 to move through the worm gear and the worm, the generated noise and vibration are small, and the phenomenon that ores are separated from the conveying belt 122 due to vibration on the conveying belt 122 can be effectively reduced.
Further, in a preferred embodiment provided herein, the rectification roller 12531 comprises a roller; the inner shaft of the rectification roller is intermittently matched and connected with the roller; in a first stroke, the inner shaft of the rectification roller 12531 continuously drives the roller to continuously move transversely relative to the mounting seat 12532; after the first stroke is exceeded, the inner shaft of the rectification roller 12531 is reset and then the roller is continuously driven to continuously move transversely relative to the mounting seat 12532.
It will be appreciated that the rollers of the rectification rollers 12531 are driven to move within the rectification roller shafts. The intermittent matching is that a reset structure is arranged between the roller and the inner shaft of the rectification roller 12531, so that the continuous rotation of the inner shaft of the rectification roller 12531 can be converted into the periodic movement and the stop of the roller. That is, after the inner shaft of the rectification roller rotates by a certain angle, the roller of the rectification roller 12531 and the inner shaft of the rectification roller are restored to the original coupled state, and the next period of movement is performed again. For example, the roller is coupled to the inner shaft of the rectification roller 12531 through a ratchet mechanism, a sheave mechanism, a cam intermittent mechanism or an incomplete gear mechanism.
The first stroke is understood to mean that the roller is in an effective coupling state with the inner shaft of the rectification roller 12531, that is, the roller is driven to translate when the inner shaft of the rectification roller 12531 rotates. The roller and the inner shaft of the rectification roller 12531 are in an effective matching state in continuous time periods, and the roller can be driven to continuously translate. The first stroke is understood to mean that the inner shafts of the roller 12531 and the rectification roller are in an invalid coupling state, that is, the inner shafts of the rectification roller 12531 and the roller are in a coupling state, but the rotation of the inner shafts of the rectification roller 12531 does not drive the roller to translate until the inner shafts of the roller 12531 and the rectification roller are restored to an effective coupling state, that is, the inner shafts of the rectification roller 12531 are reset relative to the roller. Under the rotation of the inner shaft of the rectification roller 12531, the roller is driven to continue to translate. Through rational design the translation frequency, the translation distance of roller can be realized to the adaptation structure size that resets between roller and the axle in rectifying roller 12531 to the precision that can accurate control transmission band 122 rectifies. Moreover, when the roller is in a stop state, a certain time length can be reserved for the detection device of the transmission belt 122 to detect the real-time running angle of the transmission belt 122, so that the precision of the detection of the running angle of the transmission belt 122 is increased.
Referring to fig. 3, the present application further discloses a conveyor belt deviation correcting device 200, which includes:
the conveying belt detection device 1251 is used for sending a deviation correction control signal when detecting that the driving roller slips and the included angle between the running direction of the conveying belt and the preset direction;
a deviation rectification motor 1252 for operating upon receiving the deviation rectification control signal;
and the deviation rectifying combination 1253 is driven by the deviation rectifying motor 1252 to reset the conveying belt.
The belt deviation correcting device 200 may be used to correct the running state of the belt in a running state in a circulating motion, or to serve as a carrier roller. The apparatus on which the conveyor is installed may be provided with the conveyor deviation correcting device 200 at an appropriate position according to the actual situation. However, in order to ensure the deviation rectifying effect, the deviation rectifying device 200 is preferably arranged at the roller near the material receiving end or the material separating end. In one embodiment provided herein, the conveyor belt deviation rectification device 200 is used to tension a mineral conveyor belt in the mineral separator 100.
Specifically, the conveyor belt 122 in the mineral separator 100 is driven by the drive roller 123 to move in a spreading manner, and is driven by the driven roller 124 to move in a circulating manner. The conveyor belt 122 operates normally according to a predetermined operation, and drives the ore to a predetermined separation position at a predetermined speed, and is classified by the sorting mechanism 14 in a predetermined sorting manner. However, since there is a certain error in the processing and installation of the conveyor belt 122, the conveyor belt deviates from the preset direction in the operation process, and thus the moving direction of the ore is changed, and the ore cannot be transported to the designated sorting area. In practical application, the outer ring of the transmission mechanism 12 is usually provided with a safety isolation device for preventing workers from accidentally injuring due to ore splashing, so that the workers cannot find the deviation of the transmission belt 122 at the first time. When the conveyor mechanism 12 is found to be running abnormally and the running direction of the conveyor belt 122 is readjusted, the sorted ore often needs to be sorted again, which undoubtedly reduces the efficiency of ore sorting. Therefore, it is necessary to provide a belt detecting device 1251 for detecting the moving direction of the belt 122 in the belt deviation correcting device 200. The conveying belt detecting device 1251 can detect the running direction of the conveying belt 122 by using a distance sensing method or a light detecting method.
When the conveying belt detection device 1251 detects that the running direction of the conveying belt 122 is deviated from the original preset direction, a running abnormal signal can be sent out immediately, so that the running direction of the conveying belt 122 can be adjusted immediately. That is, when the conveying belt detecting device 1251 detects the deviation of the conveying belt 122, it immediately sends out a deviation-correcting control signal. It should be noted that the running direction of the conveyor 122 here deviates from the original preset direction, i.e. there is an included angle between the running direction of the conveyor 122 and the preset direction. It can be understood that, when the conveying belt 122 is not off tracking, the included angle between the running direction of the conveying belt 122 and the preset direction is 0. Therefore, the included angle between the running direction of the conveying belt 122 and the preset direction is a value other than 0. The deviation rectifying control signal can be sent to an equipment maintenance end for exception warning. When the worker finds the abnormal warning information, the operation of the mineral product sorter 100 can be suspended, and the tensioning adjustment of the conveyor belt 122 is performed. In this way, the worker can know in time that the transport mechanism 12 is abnormally operated. However, the manual adjustment of the running direction of the conveying belt 122 undoubtedly increases the manpower input, and in the manual deviation rectifying process of the conveying belt 122, the mineral product sorting machine 100 can not be put into actual production, and undoubtedly reduces the production efficiency. In addition, although the deviation of the conveying belt 122 can be limited by arranging a plurality of vertical rollers with cylindrical shapes on the two sides of the conveying belt 122, the vertical rollers can only limit the deviation of the conveying belt 122 within a certain range, and cannot automatically correct the deviation of the conveying belt 122 and enable the conveying belt to return to a preset position, and the maintenance of the conveying mechanism 12 still needs to be manually carried out. Therefore, the tensioning adjustment signal can also be sent to the automatic conveyor belt deviation correction mechanism. When the running direction of the conveying belt 122 is detected to be abnormal, the automatic deviation rectifying mechanism of the conveying belt 122 can reach the running direction of the conveying belt 122, and the working efficiency of the mineral product sorting machine 100 is guaranteed.
Specifically, when the deviation rectifying control signal is obtained by the automatic deviation rectifying mechanism of the conveyor belt 122, the automatic deviation rectifying mechanism of the conveyor belt 122 can spread out the deviation rectifying of the conveyor belt 122. That is, a force opposite to the offset direction is applied to the conveying belt 122 to gradually return the conveying belt 122 to the original running direction, i.e., to return to the original position. It will be appreciated that the motor is capable of converting electrical energy into mechanical energy and, via the motor shaft, moves the device to which it is connected in a predetermined manner. Therefore, a motor is preferred here as a power source of the tension automatic adjusting mechanism. After the deviation rectifying motor 1252 receives the deviation rectifying control signal, the deviation rectifying assembly 1253 connected to the deviation rectifying motor 1252 and used for adjusting the running direction of the conveyor 122 can be driven according to a preset deviation rectifying mode until the conveyor 122 resets.
It should be noted that the position at which the conveyor belt 122 starts to shift varies among the different conveying mechanisms 12, and therefore, the conveyor belt deviation correcting device 200 can be installed at different positions. For example, the conveyor belt deviation rectifying devices 200 are installed at a position where the conveyor belt 122 receives ore from the feeding mechanism 11, and at several positions on the way of the sorting mechanism 14 where the conveyor belt 122 runs. Thus, the deviation of the conveying belt 122 can be found at the first time, and the adjustment of the running direction of the conveying belt 122 can be timely carried out through the deviation rectifying motor 1252 and the deviation rectifying combination 1253.
Further, in a preferred embodiment provided herein, the rectification combination 1253 includes: a leveling roller 12531 abutting the conveyor belt 122; a mounting base 12532 for mounting the rectifying roller 12531; a push rod for driving the rectifying roller 12531 to rotate relative to the mounting base 12532.
It will be appreciated that the deskew assembly 1253 deskews the conveyor 122, primarily by applying a force to the conveyor 122 in a direction opposite to the direction of its offset. Therefore, the rectification assembly 1253 is provided with the rectification roller 12531 directly contacting the conveyor belt 122 and the mounting base 12532 mounting the rectification roller 12531. In addition, in order to ensure stable operation of the rectifying rollers 12531, the mount 12532 needs to be fixed to the mineral separator 100. When the conveying belt 122 is not deviated, the deviation rectifying roller 12531 is driven by the conveying belt 122 to rotate at a certain rotation speed. When the conveying belt 122 is shifted in a certain direction, a force opposite to the shifting direction is applied to the conveying belt 122, so that the running state of the conveying belt 122 can be changed.
Specifically, a force opposite to the offset direction is applied to the conveying belt 122, mainly by adjusting the orientation of the rectification roller 12531 relative to the conveying belt 122, that is, adjusting the real-time orientation of the rectification roller 12531 by the rectification motor 1252. The real-time orientation of the rectification roller 12531 is adjusted by the rectification motor 1252, and the rectification roller 12531 is driven by the rectification motor 1252 to rotate relative to the mounting seat 12532, or the rectification roller 12531 is driven by the rectification motor 1252 to translate relative to the mounting seat 12532.
The deflection correcting roller 12531 is driven by the deflection correcting motor 1252 to rotate relative to the mounting base 12532 by means of a push rod connected to the deflection correcting motor 1252. The pushing rod can drive the deviation rectifying roller 12531 to rotate in a direction opposite to the deviation direction of the conveying belt 122 according to a preset mode under the driving of the deviation rectifying motor 1252. Here, the mounting seat 12532 reserves a certain space for the rotation of the rectification roller 12531. The push rods are preferably symmetrically disposed at both ends of the rectification roller 12531. Namely, two sets of push rods are symmetrically arranged at two ends of the rectification roller 12531 respectively. In practical application, a lead screw or a hydraulic rod can be selected as the push rod according to actual conditions. During the rotation of the rectification roller 12531, the rectification roller 12531 constantly applies a force to the transport belt 122 in a direction opposite to the offset direction thereof. Under the action of the force, the conveying belt 122 is brought back to the preset running path by the rectifying rollers 12531. In this way, the conveyor belt 122 continues to convey the ore on the original predetermined path, and prevents the ore from being separated from the conveyor mechanism 12 beyond the predetermined separation position.
Further, in a preferred embodiment provided herein, the rectification combination 1253 includes: a leveling roller 12531 abutting the conveyor belt 122; a mounting base 12532 for mounting the rectifying roller 12531; the deviation rectifying rollers 12531 are driven by the deviation rectifying motor 1252 to move laterally with respect to the running direction of the conveyor belt 122.
It will be appreciated that the deflection correcting assembly 1253 primarily adjusts the direction of travel of the conveyor 122 by controlling the orientation of the deflection correcting rollers 12531 relative to the conveyor 122. The real-time orientation of the rectification roller 12531 is adjusted by the rectification motor 1252, and the rectification roller 12531 is driven by the rectification motor 1252 to rotate relative to the mounting seat 12532, or the rectification roller 12531 is driven by the rectification motor 1252 to translate relative to the mounting seat 12532. The rectification roller 12531 is driven by the rectification motor 1252 to translate relative to the mounting base 12532, that is, the rectification roller 12531 moves towards the extending direction of the roller shaft of the rectification roller 12531 under the driving of the rectification motor 1252. The specific direction in which the rectification roller 12531 translates here is determined by the offset direction of the conveyor belt 122. For example, when the conveying belt 122 is shifted to the left in the preset direction, the deviation rectifying roller 12531 is driven by the deviation rectifying motor 1252 to move toward the right extending direction of the roller shaft of the deviation rectifying roller 12531, i.e., to traverse to the right with respect to the preset running direction of the conveying belt 122. When the conveying belt 122 is shifted to the right in the preset direction, the deviation rectifying roller 12531 is driven by the deviation rectifying motor 1252 to move towards the left extending direction of the roller shaft of the deviation rectifying roller 12531, i.e. to move transversely to the left of the preset running direction of the conveying belt 122. During the lateral movement of the deviation rectifying roller 12531 relative to the conveying belt 122, the conveying belt 122 can be brought back to the original running path. In this way, the conveyor belt 122 continues to convey the ore on the original predetermined path, and prevents the ore from being separated from the conveyor mechanism 12 beyond the predetermined separation position.
Further, in a preferred embodiment provided herein, the rectification roller 12531 continuously traverses with respect to the mounting seat 12532.
It will be appreciated that the leveling rollers 12531 translate relative to the direction of travel of the conveyor belt 122, i.e., the leveling rollers 12531 translate relative to the mounts 12532. Here, the continuous traverse, i.e., the correction roller 12531 is kept in lateral translation by the driving of the correction motor 1252, until the conveying belt 122 resumes running on the original moving path. Thus, the adjustment of the running offset of the conveying belt 122 can be continuously carried out, and the deviation rectifying efficiency of the conveying belt 122 is improved.
Further, in a preferred embodiment provided herein, a motor shaft of the deviation rectifying motor 1252 is coupled to the deviation rectifying roller 12531 through a worm gear and a worm.
The worm drives the worm wheel to rotate continuously at a certain rotation speed under the driving of the deviation rectifying motor 1252, so as to drive the deviation rectifying roller 12531 to move continuously and transversely relative to the mounting base 12532. Moreover, the rotation direction of the motor shaft is controlled by the deviation rectifying motor 1252, so that the rotation direction of the worm wheel can be controlled, and the deviation rectifying roller 12531 can translate towards different directions relative to the conveying belt 122. The motor shaft of the deviation correction motor 1252 is coupled to the worm to drive the worm gear to rotate in a predetermined manner. The rotation of the worm gear will drive the deviation rectifying roller 12531 coupled with the worm gear to transversely translate. The deviation correcting roller 12531 and the deviation correcting motor 1252 are matched and connected in a matching mode of worm and gear, so that a large speed ratio can be achieved by using a small overall dimension of the worm and gear, the occupied space of the deviation correcting motor 1252 and a transmission mechanism is saved, and the miniaturization of equipment is facilitated; and when the deviation rectifying motor 1252 drives the deviation rectifying roller 12531 to move through the worm gear and the worm, the generated noise and vibration are small, and the phenomenon that ores are separated from the conveying belt 122 due to vibration on the conveying belt 122 can be effectively reduced.
Further, in a preferred embodiment provided herein, the rectification roller 12531 comprises a roller; the inner shaft of the rectification roller is intermittently matched and connected with the roller; in a first stroke, the inner shaft of the rectification roller 12531 continuously drives the roller to continuously move transversely relative to the mounting seat 12532; after the first stroke is exceeded, the inner shaft of the rectification roller 12531 is reset and then the roller is continuously driven to continuously move transversely relative to the mounting seat 12532.
It will be appreciated that the rollers of the rectification rollers 12531 are driven to move within the rectification roller shafts. The intermittent matching is that a reset structure is arranged between the roller and the inner shaft of the rectification roller 12531, so that the continuous rotation of the inner shaft of the rectification roller 12531 can be converted into the periodic movement and the stop of the roller. That is, after the inner shaft of the rectification roller rotates by a certain angle, the roller of the rectification roller 12531 and the inner shaft of the rectification roller are restored to the original coupled state, and the next period of movement is performed again. For example, the roller is coupled to the inner shaft of the rectification roller 12531 through a ratchet mechanism, a sheave mechanism, a cam intermittent mechanism or an incomplete gear mechanism.
The first stroke is understood to mean that the roller is in an effective coupling state with the inner shaft of the rectification roller 12531, that is, the roller is driven to translate when the inner shaft of the rectification roller 12531 rotates. The roller and the inner shaft of the rectification roller 12531 are in an effective matching state in continuous time periods, and the roller can be driven to continuously translate. The first stroke is understood to mean that the inner shafts of the roller 12531 and the rectification roller are in an invalid coupling state, that is, the inner shafts of the rectification roller 12531 and the roller are in a coupling state, but the rotation of the inner shafts of the rectification roller 12531 does not drive the roller to translate until the inner shafts of the roller 12531 and the rectification roller are restored to an effective coupling state, that is, the inner shafts of the rectification roller 12531 are reset relative to the roller. Under the rotation of the inner shaft of the rectification roller 12531, the roller is driven to continue to translate. Through rational design the translation frequency, the translation distance of roller can be realized to the adaptation structure size that resets between roller and the axle in rectifying roller 12531 to the precision that can accurate control transmission band 122 rectifies. Moreover, when the roller is in a stop state, a certain time length can be reserved for the detection device of the transmission belt 122 to detect the real-time running angle of the transmission belt 122, so that the precision of the detection of the running angle of the transmission belt 122 is increased.
