The pressure sensor 84 and the rotation angle sensor 4 arranged on the stepping motor 34 are electrically connected with a processor 88, a controller 87 and a display 86 of the measurement and control center 8, the pressure sensor 84 transmits the detected gravity data of the material receiving box 81 to the processor 88 in real time, when the gravity of the material receiving box 81 is found to be increased, the processor 88 sends a control instruction to the controller 87, the controller 87 controls the stepping motor 34 to rotate to adjust the distance between the movable cone and the fixed cone, namely, the size of the discharge opening, until the gravity of the material receiving box 81 detected by the pressure sensor 84 is not increased any more.
Because the unqualified crushed materials need a certain time from the crusher 2 to the receiving box 81, the controller 87 controls the stepping motor 34 to rotate at intervals, for example, if the unqualified crushed materials need 10 seconds (or other values) from the crusher 2 to the receiving box 81, after the processor 88 sends a control instruction to the controller 87, the controller 87 immediately controls the stepping motor 34 to rotate for one circle (or other values) and then stops rotating, at the moment, the distance between the movable cone and the fixed cone is only reduced by 1 millimeter (or other values), after the stepping motor 34 stops rotating for 10 seconds (or other values), if the gravity of the receiving box 81 is still in a state of continuous increase, and the state lasts for 2-5 seconds, the processor 88 continues to send a control command to the controller 87, the controller 87 controls the stepping motor 34 to rotate for one turn and then stop rotating, then continuously waits for 10 seconds and observes whether the gravity of the material receiving box 81 is still in the continuously increased state, and as long as the gravity of the material receiving box 81 is still in the continuously increased state after 10 seconds and the state lasts for 2-5 seconds, the processor 88 repeatedly sends the control command; when the stepping motor 34 stops rotating for 10 seconds, the gravity of the material receiving box 81 keeps constant and does not increase any more, and the constant state lasts for 2 to 5 seconds, the processor 88 stops sending the control command, the adjustment of the distance between the movable cone and the fixed cone disk is finished, namely the size adjustment of the discharge port is in place.
The controller 87 controls the stepping motor 34 to stop rotating by the rotation angle sensor 4 arranged on the stepping motor 34, as mentioned above, if the distance between the movable cone and the fixed cone is set to be reduced by only 1 mm each time, the number of turns of the screw 32 required to rotate can be calculated according to the pitch of the screw 32, and then the rotation angle of the stepping motor 34 is obtained, after the controller 87 controls the stepping motor 34 to rotate, the rotation angle sensor 4 transmits the detected rotation angle data of the stepping motor 34 to the processor 88, when the rotation angle of the stepping motor 34 reaches the predetermined value, the processor 88 sends a control instruction to the controller 87, the controller 87 controls the stepping motor 34 to stop rotating, (the upper section shows that when the stepping motor 34 is defaulted to rotate by one turn, the distance between the movable cone and the fixed cone is just reduced by 1 mm, and actually, the number of turns of the stepping motor 34 and the distance between the movable cone and the fixed cone are reduced each time according to the pitch of the screw 32 Measured).
The distance between the movable cone and the fixed cone disc can be set to be reduced by 1 mm each time, and can also be set to be any value such as 0.5 mm, 2 mm and the like, the smaller the value is, the longer the time is consumed for adjusting the size of the discharge opening, but the size of the discharge opening can be easily adjusted in place; conversely, the larger the value, the shorter the time taken to adjust the size of the discharge opening, but it is not easy to adjust the size in place, and therefore the above-mentioned set value cannot be too large nor too small.
Considering that the granularity of the crushed materials required in actual production is not only one specification, but also the ore components and hardness are different, in order to conveniently adjust the parameters (such as the distance reduction amount of each adjustment of the movable cone and the fixed cone, the time interval of two adjacent adjustment actions, the time from the time when the unqualified crushed materials come out of the crusher 2 to the time when the unqualified crushed materials roll down to the material receiving box 81 and the like), the controller 87 is adapted to the crushed materials with different specifications and granularities, preferably, the controller 87 adopts a PLC (programmable logic controller) controller 87, so that a worker can conveniently rewrite a control program according to actual conditions.
The data detected by the pressure sensor 84 and the rotation angle sensor 4 are processed by the processor 88 and displayed on the display 86, the display 86 is installed on the machine table 85 (as shown in fig. 3), and the worker can know whether the size of the discharge port is adjusted in place or not by observing the data information displayed on the display 86, for example, the data information detected by the pressure sensor 84 is displayed on the display 86 at every moment, when the broken line formed by connecting the data by line segments is inclined, the size of the discharge port is being adjusted, and when the broken line is continuously horizontal, the size of the discharge port is adjusted in place, and at this moment, the crushed material is qualified.
Considering that the crushed material falling into the receiving box 81 can cause the receiving box 81 to shake, which affects the accuracy of the data detected by the pressure sensor 84, a buffer spring 82 can be arranged between the pressure sensor 84 and the receiving box 81 to buffer the shock impact of the receiving box 81 to the pressure sensor 84, which helps to prolong the service life of the pressure sensor 84.
The upper end and the lower end of the buffer spring 82 are respectively fixedly connected with the placing plate 89 and the bearing plate 83, the material receiving box 81 is placed on the placing plate 89, the bearing plate 83 is fixedly installed on the pressure sensor 84, and after the size of the discharge hole is adjusted in place, a worker moves the material receiving box 81 from the placing plate 89 to pour unqualified crushed materials into the crusher 2 for re-crushing.
The size adjustment operation of the discharge hole completely realizes automatic adjustment, manual observation, study and judgment and operation are not needed, time and labor are saved, and the practicability is good.
