[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] like Figure 1-6 As shown, a quantitative material discharge mechanism for a train loading platform includes a discharge guide bin 1, a guide plate 2, a rebound unit 3, a rebound spring 35, a connecting rod 34, and a metal bellows 32. The discharge guide bin 1 is partially fixedly connected to the material transport line via bolts, etc. It should be noted that the discharge guide bin 1... Figure 1 As shown, the longitudinal section is designed as an equilateral trapezoid, with the area of ​​the top rectangle being larger than that of the bottom rectangle. At the same time, the discharge guide hopper 1 has a through-type chamber for material guidance and discharge operations.

[0027] In order to provide multi-stage buffering for materials in the discharge guide hopper 1, two sets of guide plates 2 are installed in the discharge guide hopper 1. When in use, the guide plates 2 are rotatable in the discharge guide hopper 1 and are rotatably connected to the discharge guide hopper 1.

[0028] In order to enable the guide plate 2 to provide elastic buffering within the discharge guide chamber 1, a rebound unit 3 is provided under the guide plate 2. One end of the rebound unit 3 is connected to the bottom of the guide plate 2, and the other end of the rebound unit 3 is connected to the inner wall of the discharge guide chamber 1 to provide elastic support for the bottom of the guide plate 2.

[0029] The further springback unit 3 includes a springback spring 35, a connecting rod 34, and a metal bellows 32. The springback spring 35 is connected to the bottom of the guide plate 2. The springback spring 35 supports the bottom of the guide plate 2 without external force and supports the guide plate 2 to a position such that… Figure 4 At the designated location, the connecting rod 34 is welded to the bottom of the rebound spring 35, wherein the connecting rod 34 is as follows: Figure 4The design is inclined. To protect the spring 35 and prevent material jamming inside the spring 35, a metal bellows 32 is sleeved on the outside of the spring 35. The metal bellows 32 is located at the end of the connecting rod 34 and is detachably connected to the connecting rod 34 by bolts or the like. The metal bellows 32 is sleeved on the connecting rod 34 around the spring 35. The metal bellows 32 will contract, expand, and rotate under force during use without affecting the spring 35's rebound operation. The end of the metal bellows 32 away from the connecting rod 34 is slidably connected to the bottom of the guide plate 2.

[0030] It should be further explained that a sliding block is rotatably connected to the top of the metal bellows 32, and a sliding groove is provided at the bottom of the guide plate 2. The sliding block and the sliding groove are in an interlocking state. When in use, the sliding block will move in the sliding groove. When the guide plate 2 is under force, it will press down the rebound unit 3. At this time, the metal bellows 32 will move under the guide plate 2 under the action of the sliding block and the sliding groove. At the same time, the rebound spring 35 inside the metal bellows 32 will perform elastic buffering operation on the guide plate 2.

[0031] To ensure the connection between the connecting rod 34 and the inner wall of the discharge guide chamber 1, the second mounting part 31 is rotatably connected to the bottom of the connecting rod 34. The second mounting part 31 is connected to the inner wall of the discharge guide chamber 1. Specifically, as follows: Figure 4 and Figure 5 As shown, during use, the second mounting part 31 and the inner wall of the discharge guide chamber 1 are detachably connected through the threaded holes and bolts on the second mounting part 31, so that the connecting rod 34 can support and limit the metal bellows 32 and the damping telescopic rod 33.

[0032] To prevent the rebound spring 35 from deviating and wobbling in multiple directions during use, the damping telescopic rod 33 is fixed to the end face of the connecting rod 34 inside the rebound spring 35. During use, the damping telescopic rod 33 and the sliding block at the end of the metal bellows 32 are rotatably connected, which makes it convenient for the damping telescopic rod 33 to limit the elastic direction of the rebound spring 35.

[0033] It should be noted that during use, the second mounting part 31 and the inner wall of the discharge guide chamber 1 are detachably connected via the threaded holes and bolts on the second mounting part 31. This facilitates the connecting rod 34 to support and limit the metal bellows 32 and the damping telescopic rod 33. To prevent the rebound spring 35 from deviating and wobbling in multiple directions during use, the damping telescopic rod 33 is fixed to the end face of the connecting rod 34 inside the rebound spring 35. During use, the damping telescopic rod 33 and the sliding block at the end of the metal bellows 32 are rotatably connected, allowing the damping telescopic rod 33 to limit the elastic direction of the rebound spring 35. When the material plate 2 is impacted by the material, it will exert force on the rebound unit 3 below. At this time, the rebound spring 35 will provide elastic buffering, causing the guide plate 2 to vibrate continuously during operation. On the one hand, the material will be buffered and the impact force will be reduced at the position of the guide plate 2. At the same time, the design of the rebound unit 3 will further make the guide plate 2 continue to move, avoiding the phenomenon of material jamming between the two guide plates 2, ensuring continuous material discharge in the entire discharge guide chamber 1. The design of the metal bellows 32 will prevent the material from entering the rebound spring 35, causing the rebound spring 35 to fail to rebound.

[0034] In some embodiments, the two guide plates 2 are of different sizes, have a difference in vertical position, and the longitudinal section of the discharge guide chamber 1 is designed as an equilateral trapezoid, causing the upper guide plate 2 to be larger than the lower guide plate 2. Both guide plates 2 are inclined towards the following direction. Figure 4 At the center of the discharge guide hopper 1, when material is fed into the discharge guide hopper 1, it will first reach the upper guide plate 2. At this time, the upper guide plate 2 will perform an initial unloading operation on the material, and then... Figure 4 As shown, the material passes through the upper guide plate 2 to the lower guide plate 2, where it undergoes secondary unloading to reduce the impact force on the material entering the train transport container and to protect it.

[0035] Protective plates 12 are connected to the discharge guide chamber 1 above the guide plate 2 by bolts or the like. The guide plate 2 is rotatably connected inside the discharge guide chamber 1. The protective plates 12 protect the connection part of the guide plate 2, reducing the material from getting stuck on the rotating part of the guide plate 2. The bottom of the protective plate 12 and the guide plate 2 abut against each other. The circular design of the part where the protective plate 12 and the guide plate 2 abut against each other further reduces the weight of the train transport box.

[0036] A support rotating rod 13 is detachably installed inside the discharge guide hopper 1 by bolts or the like, and the support rotating rod 13 is set inside the guide plate 2. The support rotating rod 13 and the guide plate 2 are rotatably connected, and the support rotating rod 13 provides rotational support force for the guide plate 2.

[0037] The top of the discharge guide hopper 1 is welded with a first mounting component 11 featuring a U-shaped design. The bottom of the first mounting component 11 is welded to the top of the discharge guide hopper 1, and the U-shaped groove within the first mounting component 11 matches the size of the feed chute at the top of the discharge guide hopper 1 to ensure material conveying. The first mounting component 11 is connected to the material transport line. An infrared sensor is connected to the bottom of the discharge guide hopper 1. An infrared sensor is an electronic device that detects the presence, movement, or temperature of an object by detecting infrared radiation heat or infrared light of a specific wavelength. Its core principle is based on the interaction characteristics of infrared light with matter, and it can be divided into two categories: active and passive. The above is the disclosed technology. The infrared sensor monitors the train transport box below the discharge guide hopper 1 in real time and transmits the signal to the control panel, which then controls the material unloading status of the transport line.

[0038] It should be noted that the two guide plates 2 have a difference in vertical position, and the longitudinal section of the discharge guide chamber 1 is designed as an equilateral trapezoid, causing the upper guide plate 2 to be larger than the lower guide plate 2. Both guide plates 2 are inclined towards the following direction. Figure 4 At the center of the discharge guide hopper 1, when material is fed into the discharge guide hopper 1, it will first reach the upper guide plate 2. At this time, the upper guide plate 2 will perform an initial unloading operation on the material, and then... Figure 4 As shown, the material passes through the upper guide plate 2 to the lower guide plate 2, where it undergoes secondary unloading to reduce the impact force on the material entering the train transport box and to provide protection. The guide plate 2 is rotatably connected within the discharge guide hopper 1, and the protective plate 12 protects the connection part of the guide plate 2, reducing the risk of material getting stuck on the rotating part of the guide plate 2. The bottom of the protective plate 12 and the guide plate 2 abut against each other, and the circular design of the abutment part of the protective plate 12 and the guide plate 2 further lowers the train transport box. At the same time, the U-shaped groove in the first mounting part 11 is the same size as the feed chute at the top of the discharge guide hopper 1 to ensure material conveying. Infrared sensors monitor the train transport box below the discharge guide hopper 1 in real time and transmit the signal to the control panel, which controls the material unloading status of the transport line.

[0039] Working principle: When using the quantitative discharge mechanism of the train loading platform, an external power supply is used. Firstly, during use, the second mounting part 31 and the inner wall of the discharge guide chamber 1 are detachably connected via threaded holes and bolts on the second mounting part 31. This facilitates the connecting rod 34 in supporting and limiting the metal bellows 32 and the damping telescopic rod 33. To prevent the rebound spring 35 from deviating and wobbling in multiple directions during use, the damping telescopic rod 33 is fixed to the end face of the connecting rod 34 inside the rebound spring 35. During use, the damping telescopic rod 33 and the sliding block at the end of the metal bellows 32 are rotatably connected, facilitating the damping telescopic rod 33 in limiting the rebound spring. In the elastic direction of 35, when the guide plate 2 is impacted by material, it will exert force on the rebound unit 3 below. At this time, the rebound spring 35 will perform elastic buffering, so that the guide plate 2 will continue to shake during operation. On the one hand, the material will be buffered and the impact force will be reduced at the position of the guide plate 2. At the same time, the design of the rebound unit 3 will further make the guide plate 2 continue to move, avoiding the phenomenon of material jamming between the two guide plates 2, ensuring continuous material discharge operation in the entire discharge guide chamber 1. The design of the metal bellows 32 will prevent material from entering the rebound spring 35, causing the rebound spring 35 to fail to rebound.

[0040] Secondly, the two guide plates 2 have a difference in vertical position, and the longitudinal section of the discharge guide chamber 1 is designed as an equilateral trapezoid, causing the upper guide plate 2 to be larger than the lower guide plate 2. Both guide plates 2 are inclined towards the following direction. Figure 4 At the center of the discharge guide hopper 1 shown, when material is fed into the discharge guide hopper 1, it will first reach the position of the upper guide plate 2. At this time, the upper guide plate 2 will perform an initial unloading operation on the material, and then... Figure 4 As shown, the material passes through the upper guide plate 2 to the lower guide plate 2, where it undergoes secondary unloading to reduce the impact force on the material entering the train transport box and provide protection. The guide plate 2 is rotatably connected within the discharge guide hopper 1, and the protective plate 12 protects the connection part of the guide plate 2, reducing the risk of material getting stuck on the rotating part of the guide plate 2. The bottom of the protective plate 12 and the guide plate 2 abut against each other, and the circular design of the abutment part of the protective plate 12 and the guide plate 2 further lowers the train transport box. At the same time, the U-shaped groove in the first mounting part 11 is the same size as the feeding groove at the top of the discharge guide hopper 1 to ensure material conveying. Infrared sensors monitor the train transport box below the discharge guide hopper 1 in real time and transmit the signal to the control panel in real time. The control panel controls the material unloading status of the transport line, ultimately completing the quantitative discharge mechanism of the train loading platform.
