Description

Technical Field

[0001] This utility model belongs to the technical field of grain conveying equipment, specifically relating to a sealed bulk grain train mobile unloading conveyor belt used in grain railway transportation. Background Technology

[0002] Currently, sealed bulk grain cars, such as grain hopper cars, are typically used for transporting bulk grain by rail. These cars have a sealed compartment with a loading port at the top and a hopper discharge port at the bottom, facilitating loading and unloading. However, grain hopper cars are often quite long, and they typically have multiple loading ports at the top and hopper discharge ports at the bottom, arranged along the length of the compartment. This necessitates moving the conveyor between the loading ports and discharge ports during loading and unloading. Currently, mobile belt conveyors are commonly used for loading and unloading grain hopper cars. Existing mobile belt conveyors have casters at the tail and directional rollers at the front. The combination of the rollers and casters allows the belt conveyor to move smoothly between the loading ports and discharge ports. The forward, backward, and turning movements of belt conveyors enable their movement. However, for grain hopper cars, the distance between two adjacent loading or unloading ports is very short, and existing belt conveyors do not have the function of direct lateral movement. This means that when moving the belt conveyor between the loading or unloading ports of the grain hopper car, it is necessary to coordinate the forward, backward, and turning movements of the belt conveyor. This is not only cumbersome to operate, but also requires a large turning space, making operation very inconvenient. There is an urgent need in the market for conveying equipment suitable for loading and unloading grain hopper cars. Summary of the Invention

[0003] In summary, to overcome the shortcomings of existing technologies, this utility model provides a closed-type bulk grain train mobile unloading belt conveyor. It designs the rollers at the front of the belt conveyor as directional rollers capable of 90° rotation, allowing the belt conveyor to move laterally. When it is necessary to move between the loading and unloading ports of the grain hopper car, the directional rollers are rotated 90°, and the belt conveyor can be moved laterally. Operation is simple and convenient, requiring no conveyor rotation or turning space, effectively improving grain loading and unloading efficiency and reducing labor intensity.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0005] A sealed bulk grain train mobile unloading belt conveyor includes a belt conveyor and casters. The casters are located at the tail of the belt conveyor and connected to the frame of the belt conveyor. The conveyor also includes directional rollers located in the inclined lifting section of the belt conveyor. Each directional roller includes a support base connected to the frame of the inclined lifting section of the belt conveyor, a wheel frame rotatably connected to the support base, a roller movably connected to the wheel frame, and a power and transmission device for driving the wheel frame to rotate.

[0006] Furthermore, the wheel frame has a rotating shaft, the support base has a through hole, the rotating shaft of the wheel frame is inserted into the through hole of the support base, and the rotating shaft is connected to the through hole through a bearing assembly. The output shaft of the power and transmission device is connected to the rotating shaft of the wheel frame.

[0007] Furthermore, the power and transmission device is a speed-reduced stepper motor or a rotating handwheel.

[0008] Furthermore, the belt conveyor is a closed belt conveyor.

[0009] Furthermore, a connecting frame is provided inside the shell of the enclosed belt conveyor, and a dust baffle is fastened to the connecting frame. The dust baffle is a rubber plate or a silicone plate, and the dust baffle is in close contact with the upper conveyor belt of the enclosed belt conveyor.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention designs the front rollers of a belt conveyor as directional rollers capable of 90° rotation, allowing the belt conveyor to move laterally. When it is necessary to move between the loading and unloading ports of a grain hopper car, the directional rollers are rotated 90°, and the belt conveyor can be moved laterally. Operation is simple and convenient, requiring no conveyor steering or steering space, effectively improving grain loading and unloading efficiency and reducing labor intensity. The dust baffles in this enclosed belt conveyor effectively reduce dust generation during the transport of bulk grain materials. Attached Figure Description

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a closed-type bulk grain train mobile unloading belt conveyor includes: a belt conveyor 1 and casters 2. The casters 2 are located at the tail of the belt conveyor 1 and connected to the frame of the belt conveyor 1. The belt conveyor 1 is a closed-type belt conveyor. A connecting frame 4 is provided inside the shell 7 of the closed-type belt conveyor 1. A dust baffle 5 is fastened to the connecting frame 4. The dust baffle 5 is a rubber plate or a silicone plate. The dust baffle 5 is in close contact with the upper conveyor belt 10 of the closed-type belt conveyor 1. The system also includes a directional roller 3, which is installed in the inclined lifting section of the belt conveyor 1. The directional roller 3 includes a power and transmission device 31, a support base 32, a wheel frame 33, and rollers 34. The support base 32 is fixedly connected to the frame of the inclined lifting section of the belt conveyor 1. The support base 32 has a through hole. The wheel frame 33 has a rotating shaft 35. The rotating shaft 35 of the wheel frame 33 is installed in the through hole of the support base 32 and is connected to the through hole through a bearing assembly. The power and transmission device 31 is fixedly connected to the support base 32, and the output shaft of the power and transmission device 31 is connected to the rotating shaft 35 of the wheel frame 33. The rollers 34 are movably connected inside the wheel frame 33. The power and transmission device 31 is a reduction stepper motor or a rotating handwheel. The enclosed belt conveyor 1 includes a frame 6, a housing 7, an inlet 8, an outlet 9, a conveyor belt 10, trough idlers 11, parallel idlers 12, a driven roller 13, a driving roller 14, and a drive unit 15. The driving roller 14 is connected to the output shaft of the drive unit 15. The driving roller 14, driven roller 13, trough idlers 11, parallel idlers 12, and conveyor belt 10 constitute the belt conveyor 1. The belt conveyor 1 is arranged inside the housing 7 supported by the frame 6, forming an enclosed belt conveyor 1.

[0017] In use, push the tail of this utility model under the hopper discharge port of the grain hopper car, so that the feed port 8 of this utility model corresponds to the discharge port of the grain hopper car. Move the mobile conveying equipment under the discharge port 9 of this utility model, open the hopper discharge port of the grain hopper car, and the bulk grain material in the grain hopper car falls from the hopper discharge port and enters from the feed port 8 of the enclosed belt conveyor 1 of this utility model, falling onto the conveyor belt 10. Start the drive device 15 of the enclosed belt conveyor 1, and the drive device 15 drives the active roller 14 to rotate, thereby moving the conveyor belt 10, conveying and lifting the bulk grain material on the conveyor belt 10, and discharging it from the discharge port 9 of the enclosed belt conveyor 1, falling into the mobile conveying equipment. To achieve the unloading operation of the grain hopper car, when it is necessary to unload grain at other hopper discharge ports of the grain hopper car, the power and transmission device 31 of this utility model is started. The power and transmission device 31 drives the rotating shaft 35 to rotate 90° relative to the support seat 32, thereby causing the wheel frame 33 to rotate 90°, causing the roller to turn 90°, and then pushing this utility model laterally, pushing the feed port 8 of this utility model to below the next hopper discharge port of the grain hopper car. The above operation is repeated to carry out the unloading operation of the grain hopper car.
