Description

Technical Field

[0001] This invention relates to the field of unloading system technology, and specifically to an unloading system for unloading multiple types of goods continuously and uniformly without stopping. Background Technology

[0002] In the port logistics operation system, trains are the key carriers for bulk cargo transportation. Their unloading efficiency and smoothness play a decisive role in the overall operational efficiency of the port. At present, the traditional port train unloading mode has many drawbacks, which seriously restrict the modernization and efficiency of the port.

[0003] In traditional port unloading, to ensure stable unloading of freight cars while they are moving, the unloading tunnel is designed to be relatively long so that the cargo can be completely dumped into the tunnel during the car's journey. However, due to space constraints, some ports cannot adopt a long unloading tunnel design and can only ensure complete unloading by reducing the speed at which the cars pass through the unloading tunnel, thus reducing the unloading speed. Therefore, an unloading system for non-stop, continuous, and uniform unloading of multiple types of cargo is proposed. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, the present invention provides an unloading system for non-stop, continuous and uniform unloading of multiple types of goods.

[0005] To solve the above technical problems, the present invention provides the following technical solution: an unloading system for non-stop continuous and uniform unloading of multiple types of goods, including a truck passing through an unloading pit, several sets of unloading hoppers arranged in parallel in the unloading pit, a rail being erected on the top of each set of unloading hoppers, and a scattered material collection device being arranged on the side of the unloading pit.

[0006] The freight car travels along the rails to the top of the unloading hopper, where it dumps its cargo into the hopper. Some of the spilled cargo falls into the cargo collection equipment, which then sends the spilled cargo back into the unloading hopper.

[0007] Preferably, the unloading hopper has an asymmetrical eccentric structure, and the inner wall of the unloading hopper is equipped with a steel guard plate.

[0008] Preferably, the scattered material collection device includes a material collection trough, a hydraulic rod groove, a rotating seat, and a material collection plate. The unloading hopper has a material collection trough on one side of the truck's travel direction, and the material collection trough is connected to the unloading hopper. A hydraulic rod groove is provided in the middle of the material collection trough. A rotating seat is provided on one side of the inside of the material collection trough, and a material collection plate is installed inside the rotating seat through a rotating shaft.

[0009] Preferably, the scattered material collection device further includes a rubber sealing plate, and rubber sealing plates are fixed on both sides of the surface of the material collection plate, with the rubber sealing plates abutting against the side wall of the collection trough.

[0010] Preferably, the scattered material collection device further includes a hydraulic push rod, a lifting seat, and rollers. The hydraulic push rod is installed inside the hydraulic rod groove via a rotating shaft. The lifting seat is installed at the movable end of the hydraulic push rod, and rollers are installed at both the upper and lower ends of the lifting seat via rotating shafts.

[0011] Preferably, the hydraulic rod groove is a two-section design, with one side of the hydraulic rod groove being straight and the other side being inclined. The hydraulic push rod is located on the straight side of the hydraulic rod groove, and the lifting seat installed at the movable end of the hydraulic push rod is located on the inclined side of the hydraulic rod groove.

[0012] An unloading system for continuous and uniform unloading of multiple types of goods without stopping includes the following steps:

[0013] Step S1: Calculate the speed of the truck bed as it passes through the tunnel based on the type of cargo loaded in the truck bed;

[0014] Step S2: The freight car travels along the rail at the calculated speed. When the freight car reaches the unloading hopper, it begins to unload without stopping. The cargo is poured into the unloading hopper, and some of the cargo falls onto the surface of the cargo collection plate in the collection trough.

[0015] In step S3, after the truck bed has completely passed, the hydraulic push rod extends, and the lifting seat at the end of the hydraulic push rod moves along the inclined surface of the hydraulic rod groove under the push of the hydraulic push rod.

[0016] In step S4, the rollers at the bottom of the lifting seat gradually lift the hydraulic push rod and the end of the lifting seat upward under the guidance of the hydraulic rod groove. The rollers at the top of the lifting seat gradually come into contact with the bottom of the material collection plate under the push of the lifting seat, thereby gradually lifting the material collection plate upward.

[0017] Step S5 causes the material collection plate to tilt, thus tilting the material.

[0018] Step S6: The material entering the unloading hopper is guided by the unloading hopper into the first material conveying tunnel, and then conveyed from the first material conveying tunnel to the second material conveying tunnel.

[0019] In step S7, the second material conveying tunnel distributes the materials to the third material conveying tunnel and the first material transfer and distribution point.

[0020] Preferably, step S1 includes:

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] 1. The present invention provides an unloading area and a material collection plate. The material collection plate can collect some of the materials scattered along the freight car body, thereby avoiding the accumulation of some materials on one side of the unloading hopper and reducing manual cleaning. At the same time, by calculating the passage time of the freight car body, it can ensure sufficient unloading while determining the maximum passage speed of the freight car body to ensure unloading efficiency.

[0034] 2.

The hydraulic rod groove 42 has a two-section design; one side is straight, and the other side is inclined. The hydraulic push rod 46 is located on the straight side of the hydraulic rod groove 42, while the lifting seat 47, mounted on the movable end of the hydraulic push rod 46, is located on the inclined side of the hydraulic rod groove 42. Rollers 48 are mounted on both the upper and lower ends of the lifting seat 47 via rotating shafts. The two sets of rollers 48 contact the hydraulic rod groove 42 and the material collection plate 44, respectively, when it is necessary to move the material... When the material collection plate 44 is lifted, the hydraulic push rod 46 extends. The lifting seat 47 at the end of the hydraulic push rod 46 moves along the inclined surface of the hydraulic rod groove 42 under the push of the hydraulic push rod 46. The roller 48 at the bottom of the lifting seat 47, guided by the hydraulic rod groove 42, gradually lifts the ends of the hydraulic push rod 46 and the lifting seat 47 upward. The roller 48 at the top of the lifting seat 47 gradually contacts the bottom of the material collection plate 44 under the push of the lifting seat 47, thereby gradually lifting the material collection plate 44 upward, so that the material collection plate 44 turns into an inclined state, realizing the dumping of the material.
