Vibratory unloading machines, due to their high efficiency and energy saving, are gradually gaining market attention. The project has a very broad prospect. With the acceleration of industrial modernization, the demand for efficient and stable unloading equipment continues to grow across various industries. The material chute unloading device, optimized to address existing problems, is expected to solve material unloading difficulties, improve production efficiency, and reduce enterprise operating costs, possessing enormous development potential in the future market. Utility Model Content

[0004] The purpose of this utility model is to provide a chute unblocking device, which solves the problems of poor unloading and material blockage in the material storage and transportation process in modern industrial production, and has comprehensive technical effects.

[0005] The material chute unblocking device includes a hopper, two vibrators installed at the bottom of the hopper, a vibrating plate installed on the side wall of the hopper, and an inlet and an auxiliary inlet installed at the top of the hopper. The two vibrators are respectively installed on both sides of the bottom of the hopper and are fixedly connected to the hopper by connecting parts. The vibrating plate is fixed to the side wall of the hopper by elastic support parts. The two vibrators are controlled by a PLC controller. The PLC controller is connected to a sensor, which is used to detect the material status in the hopper.

[0006] The bottom of the silo has a conical structure, which facilitates the concentration and smooth discharge of materials.

[0007] The PLC control technology used in this solution is a mature technology. In addition, the sensor technology, after adjustment and optimization, is a technology that can be implemented by those skilled in the art, and will not be described in detail here.

[0025] This utility model provides a chute unblocking device, mainly including a hopper 1, dual vibrators 2, a vibrating plate 3, an elastic support 4, a feed inlet 5, an auxiliary feed inlet 6, a PLC controller 7, a sensor 8, a vibrating motor 9, a vibrating spring 10, a discharge port 11, a gate 12, a drive device 13, a heat dissipation device 14, a pressure sensor 15, and a temperature sensor 16. The following will be described in conjunction with the attached... Figure 1 To be continued Figure 4 The structure and working principle of this utility model are described in detail.

[0026] First, the silo 1 is designed with a conical bottom to facilitate material concentration and smooth discharge. The top of the silo 1 has an inlet 5 for feeding materials into it; the bottom has a discharge port 11 for discharging materials. A vibrating plate 3 is fixedly installed on the side wall of the silo 1, and the vibrating plate 3 is connected to the side wall of the silo 1 by multiple elastic support members 4. The vibrating plate 3 is made of a highly wear-resistant material, such as wear-resistant steel, to improve its service life. The elastic support members 4 can be springs or rubber pads, and their function is to ensure that the vibrating plate 3 has good elasticity and stability during vibration, so that the material can effectively overcome friction and cohesion under the action of the vibrating plate 3, achieving smooth discharge.

[0027] Dual vibrators 2 are installed on both sides of the bottom of the hopper 1 and are fixedly connected to the hopper 1 via connectors. Each dual vibrator 2 includes a horizontally arranged vibrating motor 9 and a vibrating plate fixed to the vibrating motor 9. The vibrating plate is provided with several vibrating springs 10, the other end of which is fixed to the bottom of the hopper 1. The function of the vibrating springs 10 is to transmit the vibration generated by the vibrating motor 9 to the bottom of the hopper 1, thereby causing the material in the hopper 1 to vibrate, so that it overcomes friction and cohesion and is discharged smoothly. The vibrating motor 9 is connected to the PLC controller 7 via wires. The PLC controller 7 controls the start and stop of the vibrating motor 9 according to the material status data detected by the sensor 8.

[0028] The PLC controller 7 is the core control unit of this invention. It stores preset material state parameters, which can be adjusted according to the characteristics of different materials. The PLC controller 7 is connected to sensors 8 via wires. Sensors 8 include a pressure sensor 15 and a temperature sensor 16, used to detect pressure and temperature changes within the silo 1, respectively. Sensors 8 transmit the detected data to the PLC controller 7 in real time. The PLC controller 7 compares the collected material state data with the preset material state parameters. When the collected material state reaches the preset value, the PLC controller 7 sends a control signal to start the vibration motor 9. Through the vibration of the vibrating plate and vibrating spring 10, the material overcomes friction and cohesion, achieving smooth unloading. Simultaneously, the PLC controller 7 also controls the drive device 13 to open the gate 12, discharging the material from the silo 1.

[0029] The vibrating motor 9 of the dual vibrator 2 is equipped with a heat dissipation device 14 to ensure the stability and reliability of the vibrating motor 9 during long-term operation. The heat dissipation device 14 includes a fan and heat sinks. The fan is connected to the PLC controller 7 via wires. The PLC controller 7 controls the start and stop of the fan based on temperature changes detected by the temperature sensor 16 to dissipate heat from the vibrating motor 9. The heat sinks are installed on the housing of the vibrating motor 9, increasing the heat dissipation area to improve the heat dissipation effect. This heat dissipation design can effectively prevent the vibrating motor 9 from being damaged due to overheating and extend the service life of the equipment.

[0030] In practical applications, the working process of the material chute unblocking device is as follows: First, the material enters the hopper 1 through the feed inlet 5. As the material accumulates, the pressure sensor 15 and temperature sensor 16 begin to detect the pressure and temperature changes in the hopper 1 and transmit the data to the PLC controller 7 in real time. The PLC controller 7 has preset material state parameters, including pressure thresholds and temperature thresholds. When the detected material pressure or temperature exceeds the preset threshold, the PLC controller 7 determines that the material state in the hopper 1 has reached a state requiring unblocking, and then sends a control signal to start the vibration motor 9 of the dual vibrators 2. The vibration generated by the vibration motor 9 is transmitted to the bottom of the hopper 1 through the vibrating plate and vibrating spring 10, causing the material in the hopper 1 to vibrate, overcome friction and cohesion, and achieve smooth flow. At the same time, the PLC controller 7 also sends a control signal to control the drive device 13 to open the gate 12, discharging the material in the hopper 1 through the discharge port 11.

[0031] In practical implementation, the conical design at the bottom of silo 1 further improves unloading efficiency. When material accumulates to a certain height in silo 1, it naturally concentrates towards the bottom due to gravity. At this time, the vibration generated by the dual vibrators 2 can act more concentratedly on the material, making it easier to overcome friction and cohesion, achieving smooth discharge. Furthermore, the high wear-resistant material design of the vibrating plate 3 greatly extends its service life and reduces equipment maintenance costs. The number and position of the elastic support members 4 can be adjusted according to actual needs to ensure that the vibrating plate 3 has optimal elasticity and stability during vibration. For example, multiple elastic support members 4 can be evenly distributed on the side wall of silo 1 to ensure uniform vibration of the vibrating plate 3.

[0032] In addition, this utility model also includes a gate 12 and its driving device 13 at the discharge port 11. The gate 12 can be driven by a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, and the driving device 13 is connected to the PLC controller 7 via a wire. When the PLC controller 7 determines that the material has reached the preset unblocking state based on the material state data detected by the sensor 8, the PLC controller 7 will send a control signal, the driving device 13 will activate, and the gate 12 will open, allowing the material to be smoothly discharged through the discharge port 11. The design of the gate 12 can also be adjusted according to actual needs. For example, gates 12 of different materials and structures can be selected to adapt to the characteristics of different materials. At the same time, the opening and closing speed and opening and closing angle of the gate 12 can also be precisely controlled by the PLC controller 7 to ensure the discharge speed and smoothness of the material.

[0033] To further improve the reliability and stability of this invention, a heat dissipation device 14 is provided on the vibratory motor 9. The heat dissipation device 14 includes a fan and heat sinks. The fan is connected to the PLC controller 7 via wires. Based on temperature changes detected by the temperature sensor 16, the PLC controller 7 controls the fan's start and stop, thus dissipating heat from the vibratory motor 9. The heat sink design increases the heat dissipation area and improves the heat dissipation effect. Specifically, the heat sink can be made of aluminum alloy, which has good thermal conductivity. The number and position of the fans can be adjusted according to the actual working conditions and heat dissipation requirements of the vibratory motor 9 to ensure the stability and reliability of the vibratory motor 9 during long-term operation.

[0034] The control logic of this utility model is as follows: When sensor 8 detects that the material pressure or temperature in silo 1 exceeds a preset threshold, PLC controller 7 will start the vibration motor 9 of the dual vibrators 2. After continuous vibration for a period of time, PLC controller 7 will again detect the material status in silo 1 through sensor 8. If the material status still has not reached the preset value, PLC controller 7 will continue to control the vibration motor 9 to vibrate until the material status reaches the preset value. When the material status reaches the preset value, PLC controller 7 will control drive device 13 to open gate 12 and discharge the material in silo 1. At the same time, PLC controller 7 will also record the time and frequency of each vibration and unloading for subsequent data analysis and fault diagnosis.

[0035] In specific application scenarios, the material chute unblocking device can be widely used in material storage and conveying processes in various industrial production. For example, in the cement production process, blockages and obstructions often occur during the storage and conveying of cement powder in the silo 1. The design of the dual vibrators 2 and vibrating plate 3 in this invention effectively overcomes these problems, ensuring smooth unloading and conveying of cement powder. The intelligent control system, consisting of the PLC controller 7 and sensor 8, can perform real-time monitoring and automatic control based on the actual state of the cement powder, improving production efficiency and product quality. Furthermore, the heat dissipation device 14 on the vibrating motor 9 ensures the stability and reliability of the vibrating motor 9 during long-term operation, preventing damage due to overheating and extending the service life of the equipment.

[0036] In the steel production process, materials such as coke and iron ore powder stored in silo 1 are prone to blockage and obstruction due to their characteristics. The material discharge chute unblocking device of this invention can also be applied to such scenarios. Through the vibration of the dual vibrators 2 and the vibrating plate 3, the material overcomes friction and cohesion, achieving smooth unloading and conveying. The intelligent control system of PLC controller 7 and sensor 8 can monitor the status of materials such as coke and iron ore powder in silo 1 in real time, ensuring the stability and continuity of the production process. Simultaneously, the high-wear-resistant material design of the vibrating plate 3 effectively resists the wear of materials such as coke and iron ore powder, extending the service life of the equipment.

[0037] In the food processing industry, powdery or granular materials stored in silo 1, such as flour and rice, are prone to blockage and obstruction. The material discharge chute unblocking device of this invention utilizes a design with dual vibrators 2 and a vibrating plate 3 to overcome friction and cohesion, achieving smooth unloading and conveying. The intelligent control system, consisting of a PLC controller 7 and sensors 8, ensures stable material conditions during food processing, preventing production interruptions due to blockages. Furthermore, the heat dissipation device 14 on the vibrating motor 9 effectively prevents overheating from prolonged operation, ensuring normal equipment operation.

[0038] In summary, the material unloading chute unblocking device of this utility model has the following significant effects: First, the design of the dual vibrators 2 and the vibrating plate 3 effectively avoids material blockage and obstruction in the hopper 1, achieving smooth unloading and conveying. Second, the conical design at the bottom of the hopper 1 further improves unloading efficiency, allowing materials to be discharged more concentratedly and smoothly. Third, the installation of pressure sensor 15 and temperature sensor 16 allows for real-time monitoring of the material status in the hopper 1, and the intelligent control by the PLC controller 7 ensures the stability and continuity of the production process. Finally, the heat dissipation device 14 on the vibrating motor 9 effectively prevents the vibrating motor 9 from overheating due to prolonged operation, ensuring the normal operation and service life of the equipment. The combination of these designs and technologies gives this utility model broad application prospects and significant technical advantages in various industrial production processes.
