Description

Technical Field

[0001] The invention belongs to the technical field of crushers, and in particular relates to an automatic unloading control method of a multi-lane automatic unloading control device of a large crusher. Background Art

[0002] The original crusher feeding method: manual scheduling is adopted. The on-site operator observes the crusher material level and the position of the ore truck in the unloading lane at the crusher command platform, and uses broadcasting to notify all vehicles in the unloading lane to prepare for unloading. The on-site operator directs the vehicles in the unloading lane to unload according to the order in which the vehicles arrive at the designated position of the unloading lane. This manual command unloading method based on experience may lead to misjudgment, which will lead to crusher blockage, and the lower belt will cause serious problems such as belt slippage, deviation, and material spillage due to unstable crusher discharge, affecting safe and civilized production. At the same time, it greatly shortens the service life of the conveyor belt, affects the smooth operation of the production system, and increases production costs. The operation is greatly affected by the weather, and the manual work intensity is high. The command unloading sequence is chaotic, unfair, and inefficient. There is a fatigue period during night operation, which poses a serious safety hazard.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. Example 1

[0040] like Figures 1 to 3 As shown, the embodiment of the present invention is a multi-lane automatic unloading control device for a large crusher, and the control device includes a crusher, a controller, a detector, a prompt module, and a conveying device. A pouring port is provided above the crusher, and a discharge port is provided below the crusher. The pouring port is provided with a number of lanes connected to the pouring port, and the discharge port is connected to the conveying device. The pouring port is in the shape of a rectangular parallelepiped, wherein three sides are the unloading surface and the other side is the blocking surface. Each unloading surface is provided with two parallel lanes, and the two parallel lanes are vertically connected to the pouring port. The large device has a total of six lanes, which are numbered in sequence, as shown in FIG. Figure 1 As shown, #1, #2, #3, #4, #5, and #6 are the lane numbers. A tower crane is installed on the outside of the other blocking surface. The crane is equipped with a dial switch for manual control, allowing the operator to observe and direct from the crane. The crane serves as an observation and command center and can also dispatch and move cargo, facilitating on-site production needs without the need for a separate command platform. The dial switches are electrically connected to the controller and contain seven dial switches in total: #1, #2, #3, #4, #5, #6, and #7. The dial switches are numbered in the same order as the lanes, with #7 being the toggle switch between automatic and manual control. The dial switches #1, #2, #3, #4, #5, and #6 control the corresponding lane's prompt module. When in manual control, the prompt module indicates to the driver whether unloading is permitted. The prompt device includes red and green indicator lights and an intelligent voice broadcast device, which uses a speaker. When unloading is possible, the green light of the corresponding lane lights up, and a voice announcement indicates that unloading is possible. For other lanes where unloading is not possible, a red light is displayed, and a voice announcement indicates that unloading is not possible. The prompt module is set on one side of the lane, with a total of six prompt modules. Preferably, in order to ensure that the driver can clearly see the red and green indicator lights and hear the intelligent voice announcement, the prompt module is set in front of the vehicle after the vehicle reaches the designated unloading position. The discharge port is connected to the conveying device through the silo. The silo is tilted and has an angle with the horizontal plane. This can reduce the splashing caused by the collision of the material with the conveying device after the material is dropped and the speed is generated during discharge, so that the material can fall more smoothly onto the conveying device, thereby improving the conveying efficiency and reducing industrial waste. One end of the silo is connected to the discharge port, and the other end is directly above the initial end of the conveying device. The conveying device uses a conveyor belt, which makes it more convenient to transport materials.

[0041] The controller is electrically connected to the detector. The detector includes a material level detection module and a vehicle detection module. The material level detection module uses a high-frequency radar material level sensor. The high-frequency radar material level sensor is installed at the inner top of the crusher. The high-frequency radar material level sensor can detect the material level in the crusher vertically downward and continuously transmit signals to the controller. The full material level of the crusher is 100%. According to the actual production requirements, the crusher control program is set with a low shutdown value of 20% and a high shutdown value of 90% for the material level in the crusher. Both shutdown values can trigger the crusher to stop. During actual operation, each truck can complete one unloading in 30 seconds. When the crusher and the discharge belt are running simultaneously and the truck is unloading normally, one unloading by a truck can increase the material level of the crusher by about 20%. When the crusher and the discharge belt are running simultaneously and there is no truck unloading, the material level of the crusher decreases by about 8% every 30 seconds. Based on long-term data monitoring of the material level value of the crusher, the saturation range of the crusher material level is calculated. The operator can set the lower limit material level one and the upper limit material level two of the material level saturation value on the touch screen in the driver's cab in combination with the actual on-site working conditions. To prevent the crusher from stopping due to slow incoming material from the unloading truck resulting in the actual material level being lower than 20%, and to keep the processing capacity of the crusher in a saturated state all the time, the unloading system control program sets the saturation lower limit material level one. To prevent the material level of the crusher from exceeding the saturation upper limit due to truck unloading, the saturation upper limit value material level two is set. The material level in the crusher monitored by the high-frequency radar material level sensor in real time is the actual material level value. The controller compares the preset material level value with the actual material level value. Assuming the actual material level is x, when the actual material level is greater than the low shutdown value set by the crusher control program and less than material level one, that is, 20% < x < material level one, two trucks are allowed to unload simultaneously. When the actual material level of the crusher is greater than material level one and less than material level two, that is, material level one < x < material level two, one truck is allowed to unload. When the actual material level value of the crusher is greater than material level two, that is, x > material level two, the controller issues a signal prohibiting unloading to prevent the material level of the crusher from reaching the high shutdown value and causing a stop.

[0042] The vehicle detection module uses an ultrasonic sensor, which is electrically connected to the controller. The ultrasonic sensor is used to identify whether the vehicle has entered the designated lane for unloading. The ultrasonic sensors are all installed on one side of the lane. Preferably, the ultrasonic sensor is installed on the side of the lane near the car body after the vehicle reaches the designated position. The ultrasonic sensor determines whether a vehicle has arrived at the designated location based on the length of time it takes for the emitted ultrasonic wave to be reflected back. When the vehicle arrives at the designated location, the ultrasonic sensor detects the vehicle and transmits the electrical signal to the controller. The controller sorts the vehicles in the corresponding lanes according to the order in which the signals are sent from the ultrasonic sensors in different lanes. The control program of the controller uses the FIFO table sorting method for sorting. The FIFO table sorting method is a sorting method based on the first-in-first-out principle. When unloading is allowed and two vehicles are allowed to unload, it is necessary to abide by the principle that adjacent lanes in different directions cannot unload at the same time, such as Figure 1 As shown, lane 2# and lane 3#, lane 4# and lane 5# are adjacent lanes in different directions, that is, vehicles in lane 2# and lane 3# cannot unload at the same time, and vehicles in lane 4# and lane 5# cannot unload at the same time.

[0043] When the control program determines that one vehicle is allowed to unload, the order of the vehicles arriving at the lane is calculated according to the FIFO table sorting method, and the vehicle ranked first unloads. The unloading time is 30s. After the time is up, the vehicle leaves. The ultrasonic sensor detects whether the vehicle has left and feeds the signal back to the controller. The material level and the priority order of the vehicles arriving at the lane are re-determined, and the unloading cycle is automatically controlled. When the control program determines that two vehicles are allowed to unload at the same time, it is also necessary to determine whether there are more than or equal to 3 vehicles in the crusher lane. If the number of waiting vehicles is greater than or equal to 3, the control program sorts the order of the vehicles arriving at the lane according to the FIFO table sorting method. According to the principle that adjacent lanes in different directions cannot unload at the same time, it is determined whether the first two vehicles in the ranking are adjacent lanes in different directions. If so, the ranking of the second and third vehicles will be swapped. After the swap, the first two vehicles in the ranking are directed to unload. If not, the first two vehicles in the ranking are directed to unload. The unloading time is allowed to be 30S. When the time is up After the vehicle leaves, the ultrasonic sensor detects whether the vehicle has left and feeds the signal back to the controller, which then re-determines the material level and the priority order of the vehicles arriving at the lane, and automatically controls the unloading cycle. If there are less than 3 vehicles, when there are 2 vehicles in the lane, the control program calculates the order in which the vehicles arrive at the lane according to the FIFO table sorting method. If the two vehicles come from different directions and non-adjacent lanes, the control program instructs the two vehicles to unload. If the two vehicles come from different directions and adjacent lanes, the vehicle with the first order will complete the unloading first, and then re-determine the material level and the priority order of the vehicles arriving at the lane, and automatically control the unloading cycle. When the unloading conditions are met and unloading is possible, the controller transmits a signal to the lane prompt module, the red and green indicator lights of the corresponding lanes turn green, and an intelligent voice broadcast indicates that unloading is possible. The red and green indicator lights of other lanes turn red, and a voice broadcast indicates that unloading is not possible.

[0044] like Figure 3 FIG. 1 is a flow chart of the control method of the present invention, and the steps of the workflow are as follows:

[0045] S1, start, start the program, whether to start the automatic mode, if so, execute S2; if not, start the manual mode and execute S14;

[0046] S2, the material level detection module detects whether the material level is greater than 20% and less than 90%. If not, the controller stops and executes S14; if satisfied, executes S3;

[0047] S3, the material level detection module detects whether the material level is less than material level 2. If so, execute S4. If not, stop pouring and return to S2 loop;

[0048] S4, the ultrasonic sensor detects whether there is a vehicle arriving at the designated unloading location. If yes, execute S5, if not, return to S4 loop;

[0049] S5: After the ultrasonic sensor detects that a vehicle has entered the designated position, it transmits a signal to the controller. Different lanes correspond to different ultrasonic sensor numbers. The controller sorts the vehicles at the designated lane positions according to the time when the ultrasonic sensor transmits the signal, and then executes S6.

[0050] S6, determine whether the material level is less than material level 1, if so, execute S7; if not, execute S12;

[0051] S7, allow two vehicles to unload materials, and execute S8;

[0052] S8, determining whether the first two vehicles in the sorting order are located in adjacent lanes in different directions. If so, execute S9; if not, execute S10;

[0053] S9, determining whether there are three or more vehicles in the lane, if so, executing S11; if not, executing S12;

[0054] S10: The first two vehicles in the queue are allowed to unload. The controller transmits a signal to the prompt module. The lanes of the first two vehicles display a green light and a voice broadcast that unloading is allowed. The lanes of other vehicles display a red light and a voice broadcast prohibiting unloading. Then, S13 is executed.

[0055] S11, swap the positions of the second and third vehicles in the sorting, and then execute S10;

[0056] S12: One vehicle is allowed to unload. The controller transmits a signal to the prompt module. The lane with the first vehicle in the queue displays a green light and a voice announcement that unloading is allowed. The other lanes with vehicles display red lights and a voice announcement prohibiting unloading. Then, S13 is executed.

[0057] S13, after unloading is completed, the vehicle is instructed to leave. The ultrasonic sensor detects the vehicle leaving and transmits the signal to the controller, and then returns to S2 to cycle;

[0058] S14, end.

[0059] Case 1

[0060] When the crusher is 100% full, with low and high level stop values ​​of 20% and 90% respectively, material level 1 is 50%, material level 2 is 70%, vehicles are in designated positions in all six lanes, and no other vehicles enter the lanes during the unloading process. After ultrasonic sensor detection, the control program in the controller arranges the vehicles in the following order: lane 2#, lane 3#, lane 4#, lane 5#, lane 6#, lane 1#. The automatic control system of the large-scale control device operates as follows:

[0061] The high-frequency radar level sensor located on the top inner side of the crusher detects that the material level is 35%, which allows two vehicles to unload. At this time, there are vehicles in all six lanes, and the order is: lane 2#, lane 3#, lane 4#, lane 5#, lane 6#, lane 1#. According to the principle that adjacent lanes in different directions cannot unload materials, it is determined that lanes 2# and 3#, which are the first two in the order, cannot unload materials at the same time. At this time, the second and third positions in the order are swapped, and the order is: lane 2#, lane 4#, lane 3#, lane 5#, lane 6#, lane 1#. Lane 2# and lane 4# are non-adjacent lanes in different directions and can unload materials. The controller transmits a signal to the prompt module that unloading is allowed. The green lights in lanes 2# and 4# illuminate, and a voice announcement reads, "Unloading is allowed." The red lights in lanes 3#, 5#, 6#, and 1# illuminate, and a voice announcement reads, "Unloading is not allowed." Vehicles in lanes 2# and 4# proceed to unload. The unloading time is 30 seconds, and after the time expires, the vehicle leaves. The ultrasonic sensor detects the vehicle's departure and transmits a signal to the controller. The high-frequency radar level sensor detects that the material level in the crusher has reached 75%, prohibiting unloading.

[0062] After 30 seconds, the high-frequency radar level sensor detects that the material level in the crusher is 67%, allowing one vehicle to unload. The controller then sorts the remaining vehicles into lanes 3, 5, 6, and 1. The green light in lane 3 illuminates, and a voice announcement announces "Unloading is permitted." The red lights in the other lanes illuminate, and a voice announcement announces "No unloading." After 30 seconds, the vehicle in lane 3 completes unloading and leaves the lane. The ultrasonic sensor detects the vehicle's departure and transmits a signal to the controller. The high-frequency radar level sensor detects that the material level in the crusher has reached 87%, prohibiting unloading.

[0063] After 30 seconds, the crusher's material level decreases by 8%, leaving 79%; unloading is prohibited. Another 30 seconds later, the high-frequency radar level sensor detects that the crusher's material level has reached 71%, prohibiting unloading. Another 30 seconds later, the high-frequency radar level sensor detects that the crusher's material level has reached 63%, allowing one vehicle to unload. The controller sorts the vehicles in lanes 5#, 6#, and 1#. Lane 5# turns green, and a voice message announces "Unloading is allowed." The other lanes turn red, and a voice message announces "No unloading." After 30 seconds, the vehicle in lane 5 completes unloading and leaves the lane. The ultrasonic sensor detects the vehicle's departure and transmits a signal to the controller. The high-frequency radar level sensor detects that the crusher's material level has reached 83%, prohibiting unloading.

[0064] After 30 seconds, the high-frequency radar level sensor detects that the material level in the crusher has reached 75%, and unloading is prohibited. After 30 seconds, the high-frequency radar level sensor detects that the material level in the crusher has reached 67%, allowing one vehicle to unload. The controller sorts the vehicles in the lanes into lanes 6# and 1#. The green light in lane 6# is on, and the voice broadcast says "unloading is allowed". The red lights in other lanes are on, and the voice broadcast says "unloading is not allowed". After 30 seconds, the vehicle in lane 6# completes unloading and leaves the lane. The ultrasonic sensor detects that the vehicle has left and transmits a signal to the controller. The high-frequency radar level sensor detects that the material level in the crusher has reached 87%, and unloading is prohibited.

[0065] After 30 seconds, the high-frequency radar level sensor detects that the material level in the crusher has reached 79%, prohibiting unloading. Another 30 seconds later, the high-frequency radar level sensor detects that the material level in the crusher has reached 71%, prohibiting unloading. Another 30 seconds later, the high-frequency radar level sensor detects that the material level in the crusher has reached 63%, allowing one vehicle to unload. The controller sorts the vehicles in the lanes, assigning them to lane 1. The green light in lane 1 illuminates, and a voice message announces "Unloading is allowed." The red lights in the other lanes illuminate, and a voice message announces "No unloading." After 30 seconds, the vehicle in lane 1 completes unloading and leaves the lane. The ultrasonic sensor detects the vehicle's departure and transmits a signal to the controller.
