Description

Technical Field

[0001] This utility model relates to the field of railway logistics equipment technology, specifically to a railway logistics unloading device. Background Technology

[0002] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0003] In modern logistics and transportation, railway transportation is widely used for transporting various types of goods due to its advantages of large capacity and long distance. However, during the railway unloading process, there is often a problem of goods falling directly onto the conveyor equipment inside the unloading device. Some large or heavy goods generate huge impact forces during the fall, which can easily cause serious damage to the conveyor belts and other equipment inside the unloading device, not only affecting the efficiency of logistics and transportation but also increasing equipment maintenance costs.

[0004] To address the aforementioned technical issues, existing technologies have incorporated corresponding innovative designs. For example, Chinese patent CN221939593U discloses a railway ore unloading device. By ensuring the steel rails possess sufficient strength and reliability to withstand the impact of large ore pieces, it effectively prevents large ore pieces from directly entering the feeding chute, avoiding direct impact on the conveyor belt within the chute. This provides protection, ensures production efficiency, and reduces maintenance costs and safety hazards. Furthermore, by replacing the limiting devices with different spacing sleeves, the screening spacing can be adjusted, demonstrating strong adaptability and applicability to various ore particle size requirements.

[0005] However, although the above-mentioned device blocks large pieces of ore through the screening device, large pieces of ore are prone to blockage when they accumulate on the screening device, and it is difficult to transport large pieces of ore. Therefore, it is necessary to continue to innovate the design in terms of structure and study a railway logistics unloading device that can solve the above-mentioned technical problems. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a railway logistics unloading device, aiming to solve the problems of large materials easily accumulating and clogging on the screening device, making transportation difficult, and causing equipment damage due to the impact of falling goods in existing railway logistics unloading devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A railway logistics unloading device includes a feeding trough, a screening device with adjustable screening spacing is provided on the top of the feeding trough, the screening device includes multiple crossbeams, and multiple steel rails with adjustable spacing are provided on the crossbeams; a conveying device is provided inside the feeding trough. The two sides of the feeding trough are inclined at different heights, and the screening device is installed at an incline on the top of the feeding trough. The screening device is located on the side near the high part of the crossbeam, and multiple large material feeding holes formed by the crossbeam are provided on the lower side of the screening device. The conveying device includes a first conveyor belt disposed below the screening device and a second conveyor belt disposed below the discharge hole; A screen is installed above the first conveyor belt, and the screen is inclined, with one lower end positioned above the second conveyor belt; A pair of crushing wheel sets are installed below the discharge hole and between the second conveyor belt to crush large pieces of material into coarse material that falls into the second conveyor belt.

[0008] Preferably, a first guide plate assembly is provided below the crossbeam to guide the material screened by the screening device to the screen.

[0009] Preferably, a second guide plate assembly is provided below the crossbeam to guide large pieces of material to the crushing wheel assembly.

[0010] Preferably, a third guide plate assembly is provided below the screen to guide the fine material screened by the screen to the first conveyor belt.

[0011] Preferably, a fourth guide plate assembly is provided below the crushing wheel assembly to guide the crushed material to the second conveyor belt.

[0012] Preferably, the crossbeam is provided with a limiting block for restricting the screening device.

[0013] This utility model has at least the following beneficial effects: In this invention, both the screening device and the side of the feeding trough are designed with an inclination. Large pieces of material automatically roll along the inclined surface of the screening device towards the large material feeding hole under the action of gravity, avoiding accumulation on the surface of the screening device. This fundamentally solves the problem of material blockage caused by material accumulation in traditional screening devices, ensuring the continuity of the unloading process. At the same time, small pieces of material directly enter the feeding trough after passing through the screening device, while large pieces of material fall directionally through dedicated feeding holes, realizing automatic diversion of materials of different sizes, reducing the workload of manual cleaning of blockages, and improving overall unloading efficiency.

[0014] In this invention, a crushing wheel assembly is installed below the large material discharge hole to crush the large material into coarse material before conveying it, solving the problem of difficult direct conveying of large materials in traditional devices and reducing the load pressure on subsequent conveying equipment. Simultaneously, a screen performs two-stage screening: fine materials fall onto the first conveyor belt through the screen, while coarse materials slide along the lower side of the screen to the second conveyor belt, achieving refined classification and conveying of materials to meet the particle size processing needs of different logistics scenarios. The two conveyor belts operate independently, avoiding the mixing of materials of different particle sizes and improving subsequent sorting efficiency. Attached Figure Description

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Figs. 1-2 A railway logistics unloading device is presented, including a feeding trough 100. The top of the feeding trough 100 is provided with a screening device with adjustable screening spacing. The screening device includes multiple crossbeams 200, and multiple steel rails 300 with adjustable spacing are provided on the crossbeams 200. For a more specific structure, please refer to the existing patent document CN221939593U. A conveying device is provided inside the feeding trough 100. In this device, the two sides of the feeding trough 100 are inclined at different heights, and the screening device is installed at an incline on the top of the feeding trough 100. The screening device is located on the side near the high point of the crossbeam 200, and multiple large material discharge holes 230 formed by the crossbeam 200 are provided on the lower side of the screening device. In this way, the material falls onto the screening device from the side of the train. Small pieces of material enter the feeding trough 100 through the screening device, while large pieces of material are screened and roll towards the large material discharge holes 230, falling into the feeding trough 100 through the large material discharge holes 230. This avoids the accumulation of large pieces of material on the screening device, which would cause blockage. At the same time, the large pieces of material also fall into the feeding trough 100 for further processing.

[0019] The conveying device includes a first conveyor belt 500 positioned below the screening device and a second conveyor belt 600 positioned below the discharge hole, arranged side by side. A screen 400 is installed above the first conveyor belt 500, and the screen 400 is inclined, with its lower end positioned above the second conveyor belt 600. This completes the secondary screening of the material. The fine material that passes through the secondary screening falls onto the first conveyor belt 500, while the coarse material screened by the screen 400 falls onto the second conveyor belt 600. A pair of crushing wheel sets 700 are installed below the discharge hole, mounted by a mounting bracket 710. Their purpose is to crush large pieces of material into coarse material, which then falls onto the second conveyor belt 600.

[0020] To effectively prevent material from splashing or scattering during its descent, the device incorporates multiple sets of flow guiding structures, as detailed below: The first guide plate group 210 is installed below the crossbeam 200. Its function is to accurately guide the small pieces of material screened by the screening device to the surface of the screen 400; guide the material to fall accurately into the effective screening area of ​​the screen 400, and reduce the decrease in screening efficiency caused by material deviation.

[0021] A second guide plate group 220 is installed below the crossbeam 200 at the corresponding large material discharge hole 230 to guide the large material to the crushing wheel group 700 in a directional manner; so that the large material enters the crushing wheel group 700 at the optimal angle, ensuring the crushing wheel's gripping and crushing effect on the material.

[0022] A third guide plate assembly 410 is installed below the screen 400, which can efficiently guide the fine materials screened by the screen 400 to the first conveyor belt 500; by guiding the fine materials to fall accurately into the center of the first conveyor belt 500, the impact of the materials on the conveyor belt is reduced, and the service life of the equipment is extended.

[0023] The fourth guide plate group 720 is configured below the crushing wheel group 700, which can smoothly guide the crushed material to the second conveyor belt 600; ensuring that all the crushed material falls into the conveying range of the second conveyor belt 600, and avoiding the accumulation of material at the bottom of the discharge trough 100, which would cause cleaning problems.

[0024] In order to rigidly limit the installation position of the screening device and ensure that it always stays in the set position, the crossbeam 200 is provided with a limiting block 240 for limiting the screening device, so as to prevent the screening device from shifting due to material impact, and at the same time prevent the diameter deviation of the discharge hole 230 of large pieces of material due to device displacement.
