[0033] As attached Figure 1-4 As shown, the embodiment of the utility model provides an automatic filling and discharging system of an intelligent filling scraper, the system comprising: a filling paste preparation system, a discharging control system and a hydraulic control unit, wherein:

[0038] The control system includes a sensor module for metering, weighing and filling materials, and can monitor and control the material level and the height of the filling slurry in real time, so as to control the entire filling material paste process. Specifically, the sensor and control system are used to achieve accurate metering, weighing and filling of materials, and can monitor and control the material level and the height of the filling slurry in real time to ensure the stability of the production process and the control of the filling quality.

[0039] In some optional implementations of this embodiment, the crushing subsystem may be composed of a crusher 25, a vibrating screen 26 and five conveyors 31, and be equipped with dust removal equipment 36; the mixing subsystem may include a mixer 29, a batching bin 28, a filling bin 33, and four electro-hydraulic unloading valves, two weighing feeders 27, two gangue feeding belt conveyors 31 and a slurry buffer bucket 32.

[0040] In some optional implementations of this embodiment, the various sensor modules include at least: an infrared sensor 20, a height sensor and an ultrasonic sensor 21, which are used to implement calculation and measurement.

[0041] Specifically, high and low limit switches are respectively provided at the top and bottom of the batching bin 28 for high and low level alarms of the powder in the batching bin 28; thereby, the powder in the batching bin 28 can be detected to avoid interruption of the system conveying process due to excessive powder overflow or too little powder.

[0042] Specifically, a radar level meter 22 is also provided on the batching bin 28 for real-time monitoring of the material level; an ultrasonic level meter 37 is installed on the filling bin 33 for monitoring the height of the filling slurry and adjusting the pumping flow of the filling pump by observing its height value. With such a configuration, the ratio of the material in the batching bin 28 to the required material and water is made more suitable and uniform through feedback adjustment, and the performance of the slurry produced by stirring is better.

[0043] In some optional implementations of this embodiment, the discharge valve 34 may be configured to determine when to open based on the height information fed back by the level meter, so that the material in the silo is at a certain height.

[0044] Specifically, the automatic charging and discharging system of the intelligent filling scraper 18 of the utility model also includes a detection unit for detecting the operating status of the scraper, and the detection unit includes: a switch 4, a pan-tilt camera 5, a signal collector 13, a power supply 15, and an inclination sensor; wherein the switch 4, the pan-tilt camera 5, the power supply 15 and the signal collector 13 are randomly distributed on one side or both sides of the scraper, the power supply 15 is used to power the signal collector 13 and the switch 4, the inclination sensor and the pan-tilt camera 5 are arranged in the middle groove of the middle groove 23 of the scraper at intervals, the inclination sensor is used to monitor the three-dimensional posture of the filling scraper, and the pan-tilt camera 5 is used to detect the discharge condition of the discharge hole on the scraper, and transmit the detected discharge image to the external main control computer. Specifically, during use, the signal collector 13 is used to collect information from each sensor, such as the data of the inclination sensor, and its main function is to convert the analog signal into a digital signal, and connect it with other devices through a communication interface for data processing or storage. When performing data conversion, the switch 4 is used to convert the signals of the pan-tilt camera 5, the signal collector 13 and the tilt sensor, and transmit the converted signals to the device to be transmitted in a certain format, such as transmitting the converted signal data to a main control computer, etc. In some optional line-of-sight modes of this embodiment, the switch is suitable for connecting multiple devices to realize network data transmission and exchange.

[0045] With such arrangement, the above-mentioned inclination sensor and pan-tilt camera 5 can not only detect the posture of the scraper machine and realize the detection of the state of the scraper machine, but also the discharging condition of the discharging port of the scraper machine can be detected through the pan-tilt camera, so as to control the charging and discharging process of the scraper machine as a whole, making the charging and discharging process effective, safe and secure.

[0046] In some optional implementations of this embodiment, the intelligent unloading system uses devices such as an inclination sensor and a pan-tilt camera 5 to realize real-time monitoring of the filling scraper. Among them, the inclination sensor is installed in the middle slot of every 5 middle slots 23, which is used to monitor the three-dimensional posture of the filling scraper, thereby effectively improving the control accuracy and safety of the filling scraper. In addition, a pan-tilt camera 5 is also configured, one for every 5 middle slots 23. The set pan-tilt camera 5 is used to monitor the situation of the unloading hole and transmit the real-time image to the main control computer connected to the outside; when the working face has problems in the filling coal mining process, the staff can perceive it in real time through the monitoring camera and deal with it in time, thereby improving production efficiency and safety.

[0047] In some optional implementations of this embodiment, taking the porous bottom-discharging filling scraper as an example, every 5 middle slots 23 are grouped into a group, for a total of 12 groups. These middle slots 23 are numbered 1#, 2#, 3#...60#, respectively. In order to achieve precise control of these middle slots 23, each group is equipped with a set of 10-function 10-interface electro-hydraulic reversing valve group 12, corresponding intrinsically safe solenoid valve driver, high-pressure filter, intrinsically safe electro-hydraulic control controller. This solution converts the electrical signal from the controller into a hydraulic signal through the electromagnetic driver, thereby controlling the opening and closing of the main valve core, and then controlling the discharge hole closing cylinder and the sliding cylinder of the porous bottom-discharging scraper conveyor 31 to complete the unloading, pushing and sliding and other tasks.

[0048] Specifically, in actual use, each middle slot 23 uses a telescopic oil cylinder and corresponding sensors, an electro-hydraulic controller 11 and other equipment to achieve precise control of the filling material. Among them, the oil cylinder has a built-in displacement sensor and an external pressure sensor 10 to monitor the stroke pressure of the oil cylinder. The electro-hydraulic controller 11 is responsible for collecting and processing these signals, and determining the telescopic distance of the oil cylinder according to the weight of the filling material. In order to facilitate signal collection and management, it is also equipped with an analog quantity collector, providing a 10-way signal input quick-plug interface to facilitate the pressure and stroke signal collection of the oil cylinder. At the same time, the controller is also equipped with an audible and visual alarm device 14 or a buzzer. When the oil cylinder is activated or opened, an audible and visual alarm prompt or a buzzer prompt will be issued to remind the operator to pay attention to safety. In this way, the control accuracy and safety of the filling material can be effectively improved.

[0049] Specifically, the displacement sensor built into the telescopic oil cylinder is further described to detect the displacement of the oil cylinder:

[0050] The working principle of the displacement sensor built into the cylinder is based on the principle of electromagnetic induction or potentiometer, which can reflect the displacement of the cylinder piston in real time and accurately. The main components of the displacement sensor include a fixed sensor part and a moving part connected to the piston. The signal is transmitted between the two parts through some form of electrical connection (such as wires or slip rings). When the cylinder piston moves, the moving part moves with it and changes its relative position with the fixed part. This position change causes the electrical parameters (such as resistance, inductance or capacitance) inside the sensor to change. The displacement sensor can calculate the displacement of the piston by measuring the changes in these electrical parameters. Specifically, if the displacement sensor is based on the principle of potentiometer, there is usually a pair of contact points between the moving part and the fixed part. As the piston moves, the resistance between the contacts changes, and this resistance change is a measure of the piston displacement. If the displacement sensor is based on the principle of electromagnetic induction, the moving part usually contains a coil and the fixed part contains a magnet. When the piston moves, the relative position between the coil and the magnet changes, causing the induced electromotive force generated in the coil to change. The change in this induced electromotive force is a measure of the piston displacement. Regardless of the principle of the displacement sensor, it is necessary to process and convert the signal through an external circuit to convert the analog signal output by the sensor into a digital signal for subsequent data processing and control. In short, the built-in displacement sensor of the oil cylinder achieves accurate measurement of the displacement of the oil cylinder piston by measuring the relative position change between the piston and the sensor.

[0051] Specifically, an end controller 1 is provided at the end of the scraper machine, and the end controller 1 is electrically connected to the power unit of the scraper machine for controlling the operation of the scraper machine.

[0052] In some optional implementations of the present embodiment, the end controller 1 is electrically or wirelessly connected to an external main control unit and a remote control device, so that the end controller 1 can be controlled through the remote control device, thereby realizing automatic charging and discharging of the scraper; or the end controller 1 can be controlled at a long distance or away from the site through an external main control unit, and controlled in an environment such as a control room, so as to realize charging and discharging control of the scraper, and at the same time, it can also avoid working in a dusty working environment to ensure the safety of the operators.

[0053] It should be noted that the purpose of configuring the end controller 1 at the position of the scraper head 3 of the intelligent unloading control system of the filling scraper is to realize the remote manual control and monitoring of the baffle of the middle slot 23 of the filling scraper, and to receive, store and upload the operating parameters of all controllers of the working face. Specifically, the end controller 1 plays a connecting role in the entire electro-hydraulic control system, and is the hub and key link of control and monitoring. Its main functions include: sending action commands to any controller to realize remote manual control of the action of the baffle of the middle slot 23 of the filling scraper; sending inspection operation parameter commands to the controller to receive and store the operating parameters of all controllers of the working face; being able to quickly modify the operating parameters of the end controller 1 and the intermediate controller; uploading the operating parameters of the filling scraper to the explosion-proof computer; by judging the real-time position and operating process section of the coal mining machine, sending action commands to the filling scrapers around the coal mining machine, automatically dropping gangue, and realizing centralized control, so that the precise control and monitoring of the baffle of the middle slot 23 of the filling scraper can be better realized, and production efficiency and safety can be improved.

[0054] In some optional implementations of this embodiment, the terminal controller 1 may be an industrial computer.

[0055] Specifically, a baffle that can be opened and closed automatically is arranged at the bottom of each middle groove 23 of the scraper.

[0056] In some optional implementations of the present embodiment, the baffle is controlled by a hydraulic cylinder, which is electrically connected to the end controller 1. A displacement sensor is provided inside each hydraulic cylinder, and a pressure sensor 10 and an electro-hydraulic controller 11 are provided outside each cylinder to monitor the displacement and pressure of the cylinder. The electro-hydraulic controller 11 is used to collect and process the signals of the displacement sensor and the pressure sensor 10, and determine the extension and retraction distance of the cylinder according to the weight of the filling material, so as to realize the opening and closing of the baffle at different angles.

[0057] In some other optional implementations of the present embodiment, the baffle can be opened and closed by means of a connecting rod mechanism in cooperation with a power device, or by means of a connecting rod structure in cooperation with a hydraulic component. For example, a four-bar linkage is adopted, the four-bar linkage is disposed on the baffle, and a power unit is disposed to drive the connecting rod to swing within a preset angle and size range to realize the opening and closing of the baffle.

[0058] With such arrangement, the opening and closing angle of the baffle can be controlled by controlling the hydraulic cylinder and the like, and further the automatic charging and discharging of the scraper can be realized.

[0059] Specifically, an alarm device is provided on the electro-hydraulic controller 11 for reminding and alarming the action of the oil cylinder.

[0060] Specifically, the hydraulic control unit includes a hydraulic support 19 , a support rear top beam, and a support front top beam. The support rear top beam and the support front top beam are respectively arranged at the front and rear of the hydraulic support 19 and are hingedly connected to the hydraulic support 19 .

[0061] In some optional implementations of this embodiment, the intelligent filling scraper conveyor 31 is equipped with a filling hydraulic support 19 control system that uses infrared sensors 20 and drop height sensors and other equipment to achieve real-time monitoring of the filling scraper. Among them, an infrared sensor 20 is installed in the front of the hydraulic support 19, which is converted into an electrical signal through infrared radiation, and is used to measure the position of the coal mining machine in real time, position the coal mining machine, and accurately grasp the filling time. In addition, an ultrasonic sensor 21 is installed next to the scraper conveyor 31 behind the support to monitor the distance between the filling material and the drop port in real time, accurately control the height of the pile, and facilitate the timely closure of the discharge port to avoid position interference with the compaction mechanism. Therefore, the production efficiency and safety of the filling scraper can be effectively improved. At the same time, in order to further improve safety, pressure sensors 10 are installed on the jacks of the front and rear columns of the hydraulic support 19, respectively, so as to monitor the stress conditions of the columns in real time. At the same time, through the calculation of pressure data, it can be determined whether the top plate is damaged during the filling process, which helps the filling hydraulic support 19 to make autonomous adjustments according to different geological conditions, thereby preventing damage to the filling hydraulic support 19.

[0062] Specifically, the use process and principle of the automatic charging and discharging system of the intelligent filling scraper 18 of the utility model are as follows:

[0063] Gangue, yellow stone, fly ash and binder are put into the crusher 25 for crushing, and the crushed materials are put into the batching bin 28 through the weighing belt conveyor; or the pre-crushed materials are directly put into the batching bin 28, and the batching bin 28 reasonably distributes the ratio of water and mixed materials according to the data collected by the gravity sensor. After the material distribution is completed, the door of the batching bin 28 is opened to allow the well-proportioned materials to fall into the mixer 29 for mixing operation; so that materials of different properties are fully mixed to form a uniform filling paste. The filling paste formed during the mixing process then falls into the receiving part 17 of the intelligent filling scraper 18, and the mixed materials are transported by the conveyor 31. In this way, the work of the filling paste preparation system forms a cycle to process the materials in the above manner. During the processing, the material is emulsified to make the filling more thorough, so that large particles or dust and other materials that are difficult or impossible to automatically charge and discharge have fluidity and conveyability. At the same time, the start, stop and extension of the scraper are controlled by the unloading control unit to realize the charging and discharging of the material, and the opening and closing degree of the middle groove 23 on the scraper is adjusted by the hydraulic component, so that the transported material can be transported according to a certain amount, and at the same time, congestion and interruption during transportation can be avoided, so that the transportation of materials has a certain continuity. Secondly, through the detection of the detection module, the posture of the scraper can be detected, as well as the detection of the discharge port, which can further better realize the automatic charging and discharging of the material on the scraper.

[0064] It should be noted that the above-mentioned mixing ratio is determined based on the specific process requirements and material properties actually required. This process helps to ensure the quality and stability of the filling paste.

[0065] In addition, the utility model is also equipped with a motor 2, a discharge cylinder 6, an intrinsically safe laser distance sensor 7, a push cylinder 8, a stroke sensor 9 and a distance sensor 24, and their connection relationship and position relationship are as follows: Figure 1-4 As shown, it is used to realize functions such as power transmission and detection.

[0066] In summary, the automatic charging and discharging system of the intelligent filling scraper 18 of the utility model adopts the method of pasting the filling material, so that the filling material becomes a filling mud similar to cement, so that the filling is more comprehensive and has no dead angles, effectively solving the problem of incomplete filling. Secondly, this filling material paste device has a simple structure and is easy to operate, which reduces the production cost. In addition, the device has the characteristics of high degree of automation, safety and reliability, and easy operation, which is conducive to improving production efficiency and safety. In order to further improve the intelligence level of the filling process, this scheme adopts an intelligent unloading control system for the filling scraper. The system realizes precise control and monitoring of the filling scraper through the synergistic effect of components such as the end controller 1 and the sensor, thereby realizing automatic opening and closing of the unloading. At the same time, the system also has functions such as an audible and visual alarm device 14 or a buzzer device, which helps to improve the safety of the operator. In addition, the use of sensors and other equipment on the hydraulic support 19 can accurately control the height of the pile and realize accurate filling. These three linkage methods together constitute a highly intelligent automatic filling process, which further improves the efficiency and safety of the filling process.
