Description

Technical Field

[0001] The invention belongs to the technical field of feeding equipment, and in particular is a quantitative feeding device for anti-icing material in an anti-icing asphalt mixture. Background Art

[0002] In cold regions, icing on roads is a serious winter traffic safety hazard. To address this issue, anti-icing asphalt mixtures are widely used as a new type of pavement material. These mixtures are typically made by mixing conventional asphalt with a certain proportion of anti-icing materials (such as antifreeze, snowmelt, or special modified materials). They effectively prevent ice formation on roads at low temperatures, improving skid resistance and driving safety. However, during asphalt mixture preparation, anti-icing material particles are prone to poor flow in hoppers or pipelines due to their high viscosity, strong hygroscopicity, or irregular particle shape. This can lead to bridging (material accumulation at the top of the hopper, preventing smooth flow) or blockage. Furthermore, the unstable flow of the particles can cause fluctuations in the discharge rate, making quantitative and precise dispensing impossible. Summary of the Invention

[0021] The material conveyor belt 1 has a feeder cover 11 fixed on one side, and the discharge port of the feeder cover 11 can be connected to the feed port of the external mixing device;

[0022] A fixing frame 13 is horizontally fixed to the upper end surface of the material conveyor belt 1, and two fixing frames 13 are arranged in an arranged manner;

[0023] The main unloading unit 2 is fixed on the fixing frame 13 on the side away from the feeder cover 11, and the feeding unit 14 is installed on the other fixing frame 13;

[0024] Side baffles 12 are installed parallel and symmetrically on both sides of the material conveyor belt 1, which can effectively prevent the anti-icing material from falling from the left and right sides of the material conveyor belt 1;

[0025] A weighing system (not shown in the figure) is arranged below the belt of the material conveyor belt 1. The weighing system is located between the main unloading unit 2 and the feeding unit 14. That is to say, the weighing system can monitor and record the weight of the anti-icing material delivered by the main unloading unit 2 on the material conveyor belt 1 in real time to ensure the accuracy and consistency of the material addition amount. The feeding unit 14 can promptly supplement the anti-icing material when the anti-icing material delivery weight is abnormal (such as insufficient material or blockage) to avoid fluctuations in the performance of the mixture due to insufficient material.

[0026] In this embodiment, the main unloading unit 2 has the same structure as the feeding unit 14; the main unloading unit 2 includes:

[0027] The side frame 21 has a material guide cover 22 fixed on its upper end surface, and a material guide plate 23 is fixed obliquely below the material guide cover 22 inside the side frame 21;

[0028] The blanking plate 3 is mounted on the side frame 21 and is located below the guide plate 23 so that the anti-icing material on the guide plate 23 can be fully dropped onto the blanking plate 3;

[0029] The storage tank 4 is vertically mounted in the material guide cover 22 , and a flow control nozzle 5 is provided at the lower end of the storage tank 4 so that the anti-icing material can be vertically delivered through the flow control nozzle 5 .

[0030] As a preferred embodiment, two rotating shafts 31 are provided in parallel on the side frame 21, and the two rotating shafts 31 are distributed up and down, and a cross frame is fixed on each of the rotating shafts 31, and the cross frame located on the upper side is fixed to the blanking plate 3;

[0031] The ends of the two cross frames are respectively connected by connecting rods 32. The two cross frames and the two connecting rods 32 can be combined to form a parallelogram linkage mechanism. A hydraulic telescopic rod 33 is installed at the lower end of the side frame 21. One end of the hydraulic telescopic rod 33 is connected to the cross frame located below. Therefore, during the telescopic adjustment of the hydraulic telescopic rod 33, the blanking plate 3 can be erected at different inclination angles as the cross frame deflects, so that the feeding angle can be dynamically adjusted according to the feeding flow rate, ensuring the flexibility and efficiency of material transportation; at the same time, when the quantitative feeding of the anti-icing material reaches the expected value, the hydraulic telescopic rod 33 can control the blanking plate 3 to rotate counterclockwise in time, so as to realize the timely collection of excess anti-icing material.

[0032] In this embodiment, an installation groove is provided in the blanking plate 3, and an oscillator 34 is configured in the installation groove so that the anti-icing material can be dispersed and transported when passing through the blanking plate 3, preventing the material from sticking due to stickiness or moisture, and to a certain extent reducing the residence time of the material on the blanking plate 3, thereby improving the overall blanking efficiency.

[0033] In this embodiment, the outer sleeve of the material storage tank 4 is coaxially provided with an outer cylinder 24, the lower end of the outer cylinder 24 is fixed to the material guide cover 22 by multiple racks; multiple inner springs 25 are distributed circumferentially between the outer cylinder 24 and the material storage tank 4;

[0034] A pulse vibration device (not shown in the figure) is installed on the side wall of the outer cylinder 24. The vibration output end of the pulse vibration device is connected to the storage tank 4. Especially during the unloading process, the pulse vibration device can continue to work at a high frequency to make the storage tank 4 vibrate and shake as a whole, so that the anti-icing material inside it can be quickly unloaded under the action of vibration, reducing the chance of blockage.

[0035] In this embodiment, a plurality of circumferentially distributed blades 51 are used below the flow control nozzle 5, and the upper ends of the blades 51 are rotatably connected to the flow control nozzle 5. An adjusting ring 52 is coaxially rotatably connected to the outside of the flow control nozzle 5. The outer peripheral wall of the adjusting ring 52 is provided with a plurality of oblique slot holes 53. A guide pin 54 is fixed to the upper side wall of the blade 51, and the guide pin 54 is slidably assembled with the oblique slot hole 53. A driving motor is provided in the flow control nozzle 5, which can drive the adjusting ring 52 to rotate in the right direction through the gear meshing action. Reverse deflection, so when the adjustment ring 52 deflects, it can control the vane 51 to deflect closer to or away from the center of the circle through the sliding of each guide pin 54 and the inclined slot hole 53, thereby adjusting the feeding and conveying diameter, so that it can be dynamically adjusted according to the specific feeding amount during use, thereby ensuring both the smoothness of feeding and the accuracy of feeding. It should be noted that the feeding and conveying diameter of the control flow nozzle 5 in the feeding unit 14 is generally not larger than the feeding and conveying diameter of the control flow nozzle 5 in the main feeding unit 2, thereby achieving more accurate feeding and conveying in the later stage.

[0036] As a preferred embodiment, a beam 41 is horizontally fixed in the storage tank 4, and a vibration tube 6 is fixed at the center of the beam 41. The vibration tube 6 can achieve a vibration guiding effect on the anti-icing material at the center position of the storage tank 4 during operation, and two ring sleeves 42 are slidably provided on the vibration tube 6. A plurality of vertically arranged guide rods 43 are distributed on the outer circumference of the ring sleeve 42, and the guide rods 43 are connected to the two ring sleeves 42 through an X-connecting frame 44; wherein, when the distance between the two ring sleeves 42 becomes smaller, each guide rod 43 can be gradually moved to the side away from the center of the circle through the X-connecting frame 44, thereby effectively controlling the specific placement position of each guide rod 43, and conveniently combining with the vibration tube 6 to provide a vibration guiding effect for the anti-icing material at different positions in the storage tank 4;

[0037] A plurality of the blades 51 are hinged with a vibration frame 45, and a guide rod is hinged in the middle of the vibration frame 45. The upper end of the guide rod is connected to a slip ring 46 slidably set on the vibration tube 6. The slip ring 46 is fixed to the upper ring sleeve 42 through a plurality of vertically fixed connecting rods 47. Therefore, when the blades 51 in the flow control nozzle 5 gradually approach the center of the circle (the discharge conveying diameter becomes smaller), each guide rod can push the upper ring sleeve 42 to slide upward through the connecting rod 47. At this time, each guide rod 43 can gradually approach one side of the center of the circle through the X connecting frame 44, so that each guide rod 43 can It can combine with the vibrating tube 6 to fully provide a vibration guiding effect for the anti-icing material near the center of the storage tank 4; and when the blade 51 in the flow control nozzle 5 gradually moves away from the center of the circle (the material discharge and conveying diameter becomes larger), each guide rod can push the upper ring sleeve 42 to slide downward through the connecting rod 47. At this time, each guide rod 43 can gradually move away from the center of the circle through the X-connecting frame 44, so that each guide rod 43 can fully provide a vibration guiding effect for the anti-icing material near the inner wall of the storage tank 4, which is convenient for providing effective vibration guiding for the entire anti-icing material, further improving the discharge speed, and avoiding internal accumulation and blockage.

[0038] In this embodiment, an inner rod 61 is coaxially connected to the vibrating tube 6. A plurality of eccentric masses 62 are distributed on the inner rod 61. Therefore, the inner rod 61 can provide a centrifugal vibration effect to the vibrating tube 6 under continuous rotation. The frequency is high, which effectively prevents the anti-icing material from condensing or clogging during the transportation process and ensures the smooth flow of the material.

[0039] A shaft sleeve 63 is slidably provided at the annular sleeve 42 located below the vibration tube 6. The shaft sleeve 63 is fixed to the annular sleeve 42 via a plurality of radially distributed couplings. A limiting spring is provided between the shaft sleeve 63 and the vibration tube 6.

[0040] A top shaft 64 is fixed on the inner rod 61, and the top shaft 64 is in contact with the lower end surface of the sleeve 63, and its contact surface is set to a bevel tooth surface structure. Especially during the continuous rotation of the inner rod 61, it can realize high-frequency axial reciprocating sliding of the lower ring sleeve 42 through the contact effect of the bevel tooth surface between the top shaft 64 and the sleeve 63, so that each guide rod 43 can achieve radial vibration effect during the high-frequency axial reciprocating sliding of the ring sleeve 42, further enhancing the vibration guide of the anti-icing material.

[0041] In this embodiment, the lower end of the inner rod 61 extends into the flow control nozzle 5, and a transmission sleeve 48 is rotatably provided on the inner rod 61. The other end of the vibration transmission frame 45 is hinged to the transmission sleeve 48. The centrifugal vibration generated by the operation of the inner rod 61 can be transmitted to the vibration transmission frame 45 through the transmission sleeve 48, and can also be transmitted to the blade 51 of the flow control nozzle 5 to a certain extent, ensuring that the vibration energy is fully distributed in the entire flow control nozzle 5, improving the overall vibration material guiding effect, and further enhancing the anti-clogging performance of the flow control nozzle 5, avoiding blockage caused by material viscosity or moisture, especially in the process of adjusting the conveying diameter, ensuring the continuity and stability of the material.

[0042] Specifically, the anti-icing material can be stored in the storage tanks 4 of the main unloading unit 2 and the feeding unit 14 respectively. The main unloading unit 2 can dynamically adjust the unloading and conveying diameter of the flow control nozzle 5 according to the specific unloading amount of the anti-icing material, thereby ensuring both the unimpeded unloading and the accuracy of the unloading. Among them, the anti-icing material can be dropped vertically through the flow control nozzle 5 and then dropped onto the unloading plate 3 through the guide plate 23. The unloading plate 3 can be erected at a corresponding inclination angle under the telescopic adjustment of the hydraulic telescopic rod 33 to ensure the flexibility and efficiency of material transportation. Then it can be dropped onto the material conveyor belt 1. At this time, the weighing system can monitor and record the weight of the anti-icing material conveyed on the material conveyor belt 1 in real time. When the conveying weight of the anti-icing material is abnormal (such as insufficient material or blockage), the feeding unit 14 supplements the anti-icing material to avoid fluctuations in the performance of the mixed material due to insufficient material, thereby realizing quantitative unloading of the anti-icing material and ensuring the accuracy of the unloading amount.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
