Description

Technical Field

[0001] This invention relates to an integrated quantitative loading system and method for bulk and bagged grain in railway open wagons, which is an automated transportation machine and an automated mechanical device for transporting bulk goods by railway. Background Technology

[0002] Bulk cargo, especially grain and similar goods, has a relatively low density. During railway transport, even when the carriages are full, the weight of the goods loaded may not reach the carriage's capacity. Therefore, it's necessary to stack the goods in the carriages as much as possible to maximize the loading capacity. This has led to a method where bulk cargo is first loaded into the carriages, and then bagged bulk cargo is stacked on top of the existing material stacks. Since the bagged cargo can be stacked higher than the carriage's side panels, this increases the loading capacity. However, current technology can only automate the loading of bulk cargo; stacking bagged cargo on top of bulk cargo still requires manual loading. Therefore, achieving fully automated bulk and bagged loading remains a problem that needs to be solved. Summary of the Invention

[0003] To overcome the problems of existing technologies, this invention proposes an integrated quantitative loading system and method for bulk and bagged grain loading in railway open wagons. The system and method include a bulk loading subsystem and a bagging subsystem, achieving full automation of both bulk and bagged loading through the alternating operation of these two subsystems.

[0004] The objective of this invention is achieved as follows: an integrated quantitative loading system for bulk and bagged grain in railway open wagons, the system comprising: a steel frame; a bulk grain conveying and buffering subsystem installed on top of the steel frame; a bulk loading subsystem and a bagged loading subsystem arranged below the bulk grain conveying and buffering subsystem along the direction of movement of the railway loading vehicles; and a wagon position adjustment subsystem installed on one side of the railway.

[0005] The bulk material conveying buffer subsystem includes: a fully enclosed conveyor, connected to the fully enclosed conveyor is a buffer silo, the bottom of the buffer silo has two bulk grain outlets, and the side has a bag grain outlet;

[0006] The bulk loading subsystem includes: two bulk grain scales arranged in a row along the direction of train travel, which cooperate with the discharge ports of the two buffer bins; each bulk grain scale has two discharge ports at the bottom; below each discharge port are four telescopic chutes that cooperate with the four discharge ports of the bulk grain scale; and a mobile leveling device installed below the bulk grain scale.

[0007] The bagged loading system includes: a bagged grain transfer device connected to the bagged grain outlet; the bagged grain transfer device connected to a quantitative bagging and packaging device; the quantitative bagging and packaging device connected to a transverse grain bag transfer device; the transverse grain bag transfer device connected to a first chute; the first chute connected to a horizontal grain bag conveyor; the horizontal grain bag conveyor connected to a grain bag turning conveyor; the grain bag turning conveyor fixedly mounted on a trolley; the trolley can run along a guide rail with the same length as the carriage; and the trolley is equipped with a second chute that can swing left and right.

[0008] The carriage position adjustment subsystem includes: a light rail with a length greater than one carriage installed on one or both sides of the railway, with ground anchors at both ends of the light rail, a traction car on the light rail, a winch on the traction car that works with the ground anchors to drive the traction car to move, and a traction arm that can be raised and lowered, and a locking buckle on the traction arm that can engage the carriage hook when the traction arm is lowered, so as to drive the train to move back and forth.

[0009] Furthermore, the mobile leveling device includes: a scraper guide rail with the same length as the carriage, a scraper plate that can move along the scraper guide rail, and a roller for moving on the scraper guide rail.

[0010] Furthermore, the steel structure frame is also equipped with a closed integrated dust removal subsystem.

[0011] A loading method using the above-described quantitative loading system, comprising the following steps:

[0012] Step 1, Empty car enters the bulk loading subsystem: An empty car enters below the four telescopic chutes of the bulk loading subsystem and comes to a stop, while the bulk grain scale weighs out the bulk grain loaded in the car.

[0013] Step 2, loading bulk grain: Four telescopic chutes are simultaneously extended into the truck bed to start discharging material. As the height of the material pile increases, the telescopic chutes are gradually raised, forming four material piles in the truck bed. When the height of the material piles is close to the truck bed, discharging stops, and the chutes are raised back to their original positions.

[0014] Step 3, Leveling: Start the mobile leveling device to move back and forth on top of the material pile, leveling the top of the material pile in the truck bed to form a flat surface that is conducive to stacking bagged grain;

[0015] Step 4, Carriage movement: Drag the carriage with the top of the material pile leveled to the bottom of the bag loading system and start the bag loading system;

[0016] Step 5, Loading bagged grain: The bulk grain in the buffer bin is transported from the bagged grain outlet to the quantitative bagging and packaging device via the bagged grain transfer device. The quantitative bagging and packaging device fills the bulk grain into bags, forming bags of grain. The bags of grain enter the carriage through the first chute, the grain bag turning conveyor, the horizontal grain bag conveyor, and the second chute. The bags of grain are continuously stacked on top of the bulk grain by the forward and backward movement of the horizontal grain bag conveyor and the left and right swing of the second chute. After the bags of grain are evenly stacked to the specified height and number of layers, the bagged grain loading operation is suspended, and the carriage filled with bulk grain and bagged grain is pulled out of the bagging and loading subsystem.

[0017] Step 6, End loading: Repeat steps 1-5 to load both bulk and bagged grain onto the entire train until the last car, thus ending the loading process for the entire train.

[0018] The advantages and beneficial effects of this invention are: This invention utilizes four subsystems—bulk material conveying and buffering subsystem, bulk loading subsystem, bagged loading subsystem, and car body position adjustment subsystem—to organically combine and form a loading process that first fills the bulk grain and then stacks the bagged grain on top. This achieves full automation of both bulk and bagged loading, solves the problem of requiring a large amount of manpower in the loading process, and improves loading efficiency.

[0025] Example 1:

[0026] This embodiment is an integrated quantitative loading system for bulk and bagged grain in railway open wagons, such as... Figure 1 , 2As shown in Figures 3 and 4, this embodiment mainly consists of four parts: a bulk material conveying and buffering subsystem, a bulk loading subsystem, a bagged loading subsystem, and a car body position adjustment subsystem. These four subsystems are organically combined to form a loading process where bulk grain is first filled and then bagged grain is stacked on top.

[0027] The system described in this embodiment specifically includes: a steel structure frame 1; a bulk grain conveying and buffering subsystem 2 installed on top of the steel structure frame; a bulk grain loading subsystem 3 and a bagged grain loading subsystem 4 arranged below the bulk grain conveying and buffering subsystem along the direction of movement of the railway loading vehicles; and a carriage position adjustment subsystem 5 installed on one side of the railway. Figure 1 , 2 3, 4.

[0028] The bulk material conveying and buffering subsystem includes: a fully enclosed conveyor 201, connected to which is a buffer silo 202. The bottom of the buffer silo has two bulk grain outlets 203, and a bag grain outlet 204 is located on the side. Figure 1 , 2 3, 4.

[0029] The bulk material conveying buffer subsystem is mainly used to transport bulk grain to a high position and temporarily store it, allowing the bulk material to fall naturally, or to fill the truck bed or grain bags. The bulk material conveying buffer subsystem mainly includes a belt conveyor that transports the bulk material to a high position, and a buffer silo for temporarily storing the bulk grain at that high position. A level sensor is installed in the buffer silo to monitor the amount of bulk grain in the silo in real time, and the conveying speed of the belt conveyor is adjusted to maintain a certain amount of bulk grain in the buffer silo to ensure loading needs. For distributed loading, this embodiment has two bulk grain outlets at the bottom of the buffer silo to correspond to two bulk scales, and a dedicated bagged grain outlet on the side of the buffer silo for bagged grain. The belt conveyor and buffer silo should be enclosed and equipped with dust removal devices to ensure the cleanliness of the grain and the surrounding environment.

[0030] The bulk loading subsystem includes: two bulk grain scales 301 arranged in a line along the direction of train travel, which cooperate with the discharge ports of two buffer silos; each bulk grain scale has two discharge ports 302 at its bottom, for a total of four discharge ports; below each discharge port are four telescopic chutes 303 that cooperate with the four discharge ports of the bulk grain scale; and a movable leveling device 304 installed below the bulk grain scales. Figure 1 , 2 4.

[0031] The bulk loading subsystem is mainly used for weighing bulk grain and loading it evenly into the truck bed. The subsystem mainly consists of a bulk grain scale, four chutes, and a crucial leveling device. This embodiment employs a stationary loading method, meaning the truck bed remains stationary during loading. To ensure the bulk grain is loaded evenly into the truck bed, this embodiment uses multiple chutes arranged along the front and rear of the truck bed. During unloading, four small, gently undulating grain piles are formed within the truck bed, creating better working conditions for the leveling device. The chutes used in this embodiment are large, telescopic chutes that extend deep into the truck bed and feature a fully enclosed dust-collecting design to ensure the cleanliness of the grain and the surrounding environment. Another important component of the bulk loading subsystem is the mobile leveling device. This device flattens the raised grain piles from the four chutes into a flat surface for stacking grain bags. The mobile leveling device uses a scraper that moves back and forth along the truck bed to level the top of the grain pile. The scraper can move back and forth multiple times to produce a good leveling effect.

[0032] The bagged loading system includes: a bagged grain transfer device 401 connected to the bagged grain outlet; the bagged grain transfer device is connected to a quantitative bagging and packaging device 402; the quantitative bagging and packaging device is connected to a transverse grain bag transfer device 403; the transverse grain bag transfer device is connected to a first chute 404; the first chute is connected to a horizontal grain bag conveyor 405; the horizontal grain bag conveyor is connected to a grain bag turning conveyor 406; the grain bag turning conveyor is fixedly mounted on a trolley 407; the trolley can run along a running guide rail 408 with the same length as the carriage; the trolley is equipped with a second chute 409 that can swing left and right. Figure 1 , 3 4.

[0033] The bagging loading system is mainly used for bagging bulk grain and stacking the bagged grain onto the bulk grain. The system consists of two main parts: bagging and stacking. Bagging begins with a bag outlet in the buffer hopper. After weighing and bagging, the grain is formed into bags. These bags are then stacked onto the bulk grain in the truck bed via a conveyor mechanism that moves along the length of the truck bed. The stacking mechanism mainly includes a swinging second chute for laterally stacking the bags in the truck bed, and a horizontal conveyor that stacks the bags along the front and back of the truck bed. Bagged grain typically needs to be stacked three to four layers onto the bulk grain. Therefore, one approach is to first stack a set of three-layer bags at one end of the truck bed, then gradually stack three-layer sets along the front and back of the truck bed. Alternatively, one approach is to first stack one layer, filling the entire truck bed with that layer before stacking the second and third layers. Both methods have their advantages and disadvantages, and should be applied flexibly in practice. However, for the stacker crane itself, the difference lies only in the operating procedures, and the equipment itself can handle it with ease.

[0034] The bagged grain transfer device is used to transport the bulk grain output from the bagged grain outlet on the buffer silo to the quantitative bagging and packaging device. The bagged grain transfer device can be a belt conveyor or a screw conveyor, etc.

[0035] Quantitative bagging packaging equipment is a mature product that is available for purchase and use. It is used to weigh bulk grains, fill them into grain bags, and seal the bags.

[0036] The lateral transfer device for grain bags is used to transport the filled grain bags laterally into the first chute. This lateral transfer device can be a belt conveyor or other mechanical equipment that facilitates the transport of grain bags, such as a bag unwinding machine.

[0037] The first chute is used to allow the grain bags to fall along the chute using gravity, so that they can enter the horizontal grain bag conveyor.

[0038] The function of a horizontal grain bag conveyor is to transport grain bags horizontally to their stacking location. Grain bags are typically stacked from front to back, with each stack moving backward one step at a time, and this backward movement continues as the stacking progresses. The length of the horizontal conveyor should be the same as or slightly longer than the length of the wagon compartment to ensure the grain bags can be transported to various positions within the compartment. Horizontal grain bag conveyors can utilize equipment such as belt conveyors to transport the grain bags.

[0039] The grain bag turning conveyor is used to remove grain bags from the horizontal grain bag conveyor and transfer them to the second chute. The horizontal grain bag conveyor is mounted on a trolley and moves back and forth with it. The main function of the horizontal grain bag conveyor is to address the issue of the forward and backward positioning of the grain bags; the specific position of the grain bags is determined by the position of the trolley.

[0040] The trolley plays a crucial role, primarily used for stacking and arranging grain bags within the wagon's compartment. The trolley can move back and forth on guide rails, such as... Figure 1 , 4 The trolley moves in the direction of arrow D to determine the front and rear positions of the stacked grain bags within the carriage. The trolley can be driven by an electric motor or a winch.

[0041] The main function of the second chute is to arrange the grain bags left and right. The second chute works by oscillating, such as... Figure 3 , 4 Swing in the direction of the middle arrow E to arrange the grain bags horizontally.

[0042] It should be noted that the front, back, left, and right directions described in this embodiment and the next embodiment refer to the front, back, left, and right directions as usually indicated by the forward direction of a vehicle. Figure 1 , 4 In the diagram, the left side of the paper represents the direction the vehicle is moving forward; that is, left is front and right is back. The left and right sides are divided according to the view.

[0043] The aforementioned carriage position adjustment subsystem includes: a light rail 501, longer than one carriage, installed on one or both sides of the railway; ground anchors 502 at both ends of the light rail; a traction car 503 mounted on the light rail; a winch 504 mounted on the traction car, which works in conjunction with the ground anchors to drive the traction car's movement; and a traction arm 505 capable of being raised and lowered, with a locking buckle 506 on the traction arm that engages with the carriage hook when the traction arm is lowered, for driving the train to move back and forth. Figure 1 , 3 4.

[0044] Freight trains often consist of multiple carriages, making it difficult to use a locomotive to move the carriages back and forth to find a precise stopping position. However, loading bagged grain requires precise positioning, and loading bagged grain is a lengthy process. Using a dedicated locomotive for loading would be costly. To address this issue, this embodiment incorporates a carriage position adjustment subsystem. During loading, this subsystem moves the train forward and can also move it slightly back and forth without requiring a dedicated locomotive. The carriage position adjustment subsystem described in this embodiment uses light rails on one or both sides of the railway, with trolleys mounted on these rails. A winch and ground anchors are used to move the trolleys back and forth. A traction arm that can be raised and lowered is mounted on the trolley; when lowered, it engages the coupler on the carriage, moving the carriage back and forth.

[0045] Example 2:

[0046] This embodiment is an improvement on the above embodiment and a refinement of the mobile leveling device in the above embodiment. The mobile leveling device in this embodiment includes: a scraper guide rail with the same length as the carriage, a scraper plate that can move along the scraper guide rail on the scraper guide rail, and a roller for moving on the scraper guide rail on the scraper plate.

[0047] Because grain has good fluidity, this embodiment uses a scraper to repeatedly move on the top of the grain pile to level the top of the grain pile, or a combination of scraper and flat rake is used.

[0048] Example 3:

[0049] This embodiment is an improvement upon the above embodiment, a refinement of the steel structure frame described above. The steel structure frame in this embodiment is further equipped with a closed-loop integrated dust collection subsystem 6, such as... Figure 1 .

[0050] Dust control mainly involves sealing off the grain inlets and outlets to prevent dust from being stirred up during the unloading process.

[0051] Example 4:

[0052] A loading method using the aforementioned quantitative loading system involves the following basic steps: With the truck bed stationary, multiple troughs are used to evenly fill the bed with material, ensuring a relatively uniform accumulation of bulk grain. A leveling scraper then flattens the top of the pile into a surface suitable for stacking grain bags. Finally, a mechanized grain bag conveying system neatly and evenly stacks the grain bags on top of the bulk grain. The height of the stacked grain bags can exceed the height of the truck bed's side panels, thereby maximizing the utilization of the truck bed's load capacity. The specific steps of this embodiment are as follows:

[0053] Step 1, Empty car enters the bulk loading subsystem: An empty car enters below the four telescopic chutes of the bulk loading system, while the bulk grain scale weighs out the bulk grain loaded in the car.

[0054] Before loading, a sufficient quantity of bulk grain should be stored in the buffer compartment, exceeding the loading capacity of two wagons. This wagon can be the first wagon or any wagon in the train. When the first wagon enters, it is usually pulled in by a locomotive. Subsequent loading processes can utilize the wagon positioning subsystem to adjust the wagon's position without the need for locomotive traction.

[0055] Step 2, loading bulk grain: Four telescopic chutes are simultaneously extended into the truck bed to start discharging material. As the height of the material pile increases, the telescopic chutes are gradually raised, forming four material piles in the truck bed. When the height of the material piles approaches the truck bed, discharging stops, and the chutes are raised back to their original positions.

[0056] Because the four chutes load the grain simultaneously, the loading process is very fast and can usually be completed in just a few minutes.

[0057] Step 3, Leveling: Start the mobile leveling device to move back and forth on top of the material pile, leveling the top of the material pile in the truck bed to form a flat surface that is conducive to stacking bagged grain.

[0058] The leveling process should be repeated several times to ensure that the top of the grain pile is very flat, which will facilitate the stacking of grain bags.

[0059] Step 4, Carriage Movement: Drag the carriage, after leveling the top of the material pile, under the bagging loading system and start the bagging loading system.

[0060] The process of moving the carriage is completed by the carriage position adjustment subsystem. The tractor moves to the position where the two carriages are connected, lowers the traction arm, and uses the lock to fasten the carriage hook. The winch is started to pull the carriage back and forth to adjust the carriage to a suitable loading position.

[0061] Step 5, Loading of bagged grain: The bulk grain in the buffer bin is transported from the bagged grain outlet to the quantitative bagging and packaging device via the bagged grain transfer device. The quantitative bagging and packaging device fills the bulk grain into bags, which then pass through the first chute, the horizontal bag conveyor, the bag turning conveyor, and the second chute into the truck bed. The bags are continuously stacked on top of the bulk grain by the forward and backward movement of the horizontal bag conveyor and the left and right swinging of the second chute. After the bags are evenly stacked to the specified height and number of layers, the bagged grain loading operation is suspended, and the truck bed filled with both bulk grain and bagged grain is pulled out of the bagging and loading subsystem.

[0062] The process of stacking grain bags mainly involves a trolley driving a grain bag turning conveyor, a second chute determining the front and rear positions of the grain bags, and the swinging of the second chute determining the left and right positions of the grain bags.

[0063] Step 6, End loading: Repeat steps 1-5 to load both bulk and bagged grain onto the entire train until the last car, thus ending the loading process for the entire train.

[0064] Finally, it should be noted that the above is only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred arrangement, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the present invention (such as the loading method of bulk grain, the loading method of grain bags, the form of loading station, the order of steps, etc.) without departing from the spirit and scope of the technical solution of the present invention.
