AI Technical Summary
In the current technology, unloading bulk granular materials from train carriages mainly relies on manual labor or equipment, which is costly and inefficient.
By combining an excavator with a belt conveyor, the excavator pushes the material to the discharge port, and the belt conveyor transports the material between the excavator and the track, achieving efficient material transfer.
It improves the efficiency of train unloading, meets the unloading needs, and has a reasonable overall design that does not affect the operation of excavators.

Abstract
Description
Technical Field
[0001] This invention relates to the field of train unloading technology, and in particular to a train unloading system. Background Technology
[0002] Most freight yards rely mainly on manual labor or other equipment to unload bulk granular materials from train carriages, which is costly or inefficient. To address this problem and improve the mechanization of train unloading, this invention aims to address this issue. Summary of the Invention
[0003] In view of this, the present invention proposes a train unloading system, the specific technical solution of which is as follows:
[0004] A train unloading system includes an excavator body and a belt conveyor. The excavator has two tracks underneath it, and the belt conveyor is located between the excavator body and the tracks. One end of the belt conveyor is equipped with a guide chute, which is located below the discharge port of the corresponding train car. The material coming out of the train discharge port is fed into the guide chute and then transported by the belt conveyor to the other end, where it naturally falls into a pile.
[0005] Furthermore, the belt conveyor has a bandwidth of 1600 mm.
[0006] Furthermore, the excavator body is raised by 2 meters from the slewing position using a four-post chassis.
[0007] Furthermore, the guide trough is fixed on the belt conveyor.
[0008] The above technical solution has the following beneficial effects:
[0009] This invention connects and coordinates an excavator and a belt conveyor. The excavator pushes materials from inside the train car to the discharge port, while the belt conveyor transports the materials. The belt conveyor passes between the excavator body and the tracks, without affecting the excavator's operation. The overall design is reasonable, improves the efficiency of train unloading, and meets unloading requirements. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of the present invention;
[0011] In the diagram: 1-Train carriage; 2-Wheel; 3-Chassis; 4-Excavator body; 5-Discharge port; 6-Belt conveyor; 7-Crawler; 8-Guide chute. Detailed Implementation
[0012] The invention will now be further described with reference to the accompanying drawings.
[0013] like Figure 1The diagram shows the structure of the present invention. The excavator is raised by four pillars from the swing position, with the height increase being approximately 2 meters. The specific height is determined based on the excavator model and the work site. A belt conveyor 6 with an hourly capacity of 3000 tons (1600mm wide) is installed between the excavator body 4 and the tracks 7 (at the location of the raised four-pillar structure). The conveyor can be hydraulically adjusted in front, back, height, and low position. An inverted trapezoidal guide chute 8 is installed at the front of the conveyor to receive materials. During operation, the guide chute 8 is located below the discharge port 5 of the train car 1. After the discharge port 5 of the train car 1 is opened, the bulk materials fall into the guide chute 8 along the lower door of the train, and are then transported by the belt conveyor 6 to the rear of the belt conveyor 6 to naturally fall. If the materials cannot fall by themselves, the excavator bucket is used to scoop the materials to the discharge port 5 until they fall naturally. The belt conveyor 6 is electrically driven, and the power supply is provided by a mobile generator or a mobile cable.
[0014] The specific structure is as follows: a train unloading system includes an excavator body 4 and a belt conveyor 6. A chassis is provided below the excavator body 4, and two tracks 7 are provided below the excavator. The belt conveyor 6 is provided between the excavator body 4 and the tracks 7. A guide chute 8 is provided at one end of the belt conveyor 6. The guide chute 8 is located below the discharge port 5 corresponding to the train car 1. The material coming out of the train discharge port 5 is transferred into the guide chute 8, and then transported by the belt conveyor 6 to the other end where it falls naturally into a pile. The belt width of the belt conveyor 6 is 1600 mm. The excavator body 4 is raised by 2 meters from the rotating position using a four-column chassis 3. The guide chute 8 is fixed on the belt conveyor 6.
[0015] In this embodiment, the belt conveyor 6 transports goods at an upward angle. In other embodiments, the direction of the belt conveyor 6 can be specifically designed as needed.
[0016] In this embodiment, the excavator is used to scoop materials to the discharge port 5 when the materials cannot fall by themselves, until they fall naturally.
[0017] In this embodiment, the material is transported to the other end by the belt conveyor 6 and then falls freely to the ground. In other embodiments, a collection device such as a loading cart can be placed at the other end of the belt conveyor 6.
[0018] This invention connects and cooperates an excavator with a belt conveyor 6. The excavator is used to push the material in the train car 1 to the discharge port 5. The train car is equipped with wheels 2 underneath. The belt conveyor 6 transports the material. The belt conveyor 6 passes between the excavator body 4 and the track 7 without affecting the operation of the excavator. The overall design is reasonable, improves the efficiency of train unloading, and meets the unloading requirements.
[0019] The basic principles and main features of the present invention have been described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention. All such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the invention is defined by the appended claims and their equivalents.
