Description

Technical Field

[0001] This application relates to the field of railway track bed cleaning technology, specifically to a ballast storage hopper. Background Technology

[0002] The side-cutting turnout cleaning machine using a blade-type excavation device requires the excavation blade to rotate in and out at the start and end of excavation. To ensure proper backfilling of ballast, a ballast storage hopper is needed to balance the ballast flow. Furthermore, the ballast storage hopper needs a large storage capacity. Currently used ballast storage hoppers only have floor conveyor belts. To store more ballast in the hopper, the floor conveyor belt needs to rotate in the direction of ballast jamming. Once ballast gets stuck between the conveyor belt and the hopper, it causes damage to the conveyor belt, reduces its lifespan, and increases maintenance workload.

[0003] To improve the lifespan of the floor conveyor belt and reduce maintenance workload, the operating costs of the machinery were reduced in terms of materials and labor; at the same time, the capacity of the ballast buckets was fully utilized.

[0004] Therefore, the floor conveyor belt of traditional ballast storage hoppers has a high damage rate, resulting in insufficient durability of the ballast storage hoppers, which is a technical problem that urgently needs to be solved by those skilled in the art.

[0005] The information disclosed in the background section is only intended to enhance the understanding of the background of this application, and therefore may contain information that is not part of the prior art known to those skilled in the art. Utility Model Content

[0006] This application provides a ballast storage hopper to solve the technical problem that the floor conveyor belt of traditional ballast storage hoppers has a high damage rate, resulting in insufficient durability of the ballast storage hopper.

[0007] This application provides a ballast storage hopper, comprising:

[0008] Ballast bucket body;

[0009] A floor conveyor belt is installed at the bottom of the ballast storage bucket body;

[0010] A ballast-scraping device for leveling and moving ballast inside the ballast storage bucket is located at the top of the ballast storage bucket and extends into the ballast storage bucket.

[0011] The embodiments of this application, by adopting the above technical solutions, have the following technical effects:

[0012] The ballast storage hopper of this application not only has a floor conveyor belt, the function of which is to move the incoming ballast at the bottom of the ballast storage hopper; but also has a ballast scraping device, which is set at the top of the ballast storage hopper body 1 and extends into the ballast storage hopper body. The function of the ballast scraping device is to scrape and move the ballast in the ballast storage hopper body from the top of the ballast.

[0013] In situations where moving ballast using a floor conveyor belt is not feasible, including but not limited to cases where moving the ballast at the bottom of the ballast hopper would damage the conveyor belt, a ballast-scraping device is used to level and move the ballast from the top of the ballast within the hopper. This protects the floor conveyor belt, reduces its damage frequency, improves its durability, and lowers the operating cost of the ballast hopper.

[0014] The system employs two working methods: a floor conveyor belt to move the ballast and a ballast-scraping device to level and move the ballast from the top. These methods can be coordinated according to the actual situation and timing. The floor conveyor belt moves the ballast from the bottom of the ballast storage hopper, while the ballast-scraping device levels and moves the ballast from the top, resulting in high work efficiency.

[0015] The ballast storage hopper of this application embodiment has a simple structure, strong durability, and high working efficiency; it also makes full use of the capacity of the ballast storage hopper. Attached Figure Description

[0028] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown in the figure, an embodiment of this application provides a ballast storage hopper, comprising:

[0031] Ballast bucket body 1;

[0032] Floor conveyor belt 2 is installed at the bottom of the ballast hopper body 1;

[0033] A ballast-scraping device 3, used for leveling and moving the ballast inside the ballast storage bucket 1, is located at the top of the ballast storage bucket 1 and extends into the ballast storage bucket 1.

[0034] The ballast storage hopper of this application not only has a floor conveyor belt, the function of which is to move the incoming ballast at the bottom of the ballast storage hopper; but also has a ballast scraping device, which is set at the top of the ballast storage hopper body 1 and extends into the ballast storage hopper body. The function of the ballast scraping device is to scrape and move the ballast in the ballast storage hopper body from the top of the ballast.

[0035] In situations where moving ballast using a floor conveyor belt is not feasible, including but not limited to cases where moving the ballast at the bottom of the ballast hopper would damage the conveyor belt, a ballast-scraping device is used to level and move the ballast from the top of the ballast within the hopper. This protects the floor conveyor belt, reduces its damage frequency, improves its durability, and lowers the operating cost of the ballast hopper.

[0036] The floor conveyor belt 2 moves the ballast, and the ballast removal device moves and leveles the ballast from the top. Depending on the actual situation and timing, the floor conveyor belt 2 moves the ballast at the bottom of the ballast hopper, while the ballast removal device moves and leveles the ballast from the top, resulting in high work efficiency.

[0037] The ballast storage hopper of this application embodiment has a simple structure, strong durability, and high working efficiency; it also makes full use of the capacity of the ballast storage hopper.

[0038] During implementation, such as Figure 1 , Figure 2 , Figure 5 As shown, the ballast removal device 3 includes:

[0039] Mounting bracket 31 is suspended and installed on the top of the ballast bucket body 1;

[0040] A bracket 32 ​​is connected to the lower part of the mounting bracket, and the bracket 32 ​​has an elongated elliptical outer peripheral surface;

[0041] The drive sprocket assembly 33, the driven sprocket assembly 34, and the ballast raking chain 35 are meshed with the sprockets of the drive sprocket assembly and the driven sprocket assembly, and the ballast raking chain are connected to the elongated elliptical outer circumferential surface of the support.

[0042] Multiple strips 36 are arranged at intervals along the ballast chain.

[0043] By suspending the mounting frame on the top of the ballast storage bucket 1, a flexible connection between the ballast removal device and the ballast storage bucket body is achieved, which facilitates the adjustment of the working position of the ballast removal device and adapts to the operational needs under different working conditions.

[0044] The support frame features an elongated elliptical outer surface design, allowing the drive sprocket assembly, driven sprocket assembly, and ballast removal chain to fit more closely against the support surface, improving transmission efficiency and stability. The elongated elliptical design helps optimize the movement trajectory of the ballast removal chain and blades, ensuring that the ballast is leveled and moved evenly and effectively, thus enhancing the ballast removal effect.

[0045] The precise meshing connection between the drive sprocket assembly and the driven sprocket assembly ensures the smooth operation of the ballast screed chain, reduces chain skipping and wear, and extends the maintenance cycle of the equipment.

[0046] This design allows the ballast removal chain to efficiently drive multiple ballast removal blades in continuous operation, improving both removal efficiency and quality. The multiple blades, spaced apart on the ballast removal chain, not only increase the ballast coverage area but also effectively prevent ballast accumulation, ensuring even distribution. The blade design ensures that each removal action more thoroughly moves and disperses the ballast, further enhancing the precision and efficiency of the removal process.

[0047] In practice, as an optional method, the drive sprocket assembly drives the ballast chain to rotate in one direction.

[0048] In practice, as an optional method, the drive sprocket assembly 33 drives the ballast chain 35 to rotate in both directions.

[0049] By enabling the drive sprocket assembly to rotate the ballast-removing chain in both directions, the ballast-removing device achieves operational capability in different directions. This bidirectional operational capability allows the equipment to flexibly adjust the ballast-removing direction according to actual site conditions, adapting to a wider range of operational needs.

[0050] The bidirectional rotation function allows the ballast-scraping chain to operate continuously in two directions, effectively avoiding the problems of ballast accumulation or uneven distribution that may occur with unidirectional ballast scraping. This not only increases the processing speed of ballast but also improves the flatness and uniformity of the ballast.

[0051] During implementation, such as Figure 1 and Figure 2 As shown, there are two sets of ballast removal devices 3, which are arranged side by side on the top of the ballast storage bucket body 1.

[0052] By setting up two sets of ballast removal devices to work in parallel, more ballast can be processed simultaneously, significantly improving the speed of ballast leveling and movement. This not only speeds up the entire operation process but also enables a more rapid response to high-load work demands.

[0053] The design of the double-set ballast removal device allows the ballast to be evenly distributed and leveled over a larger area. Compared to a single-set device, the double-set device can provide a wider coverage area, ensuring a higher flatness of the ballast layer and reducing local ballast accumulation or insufficiency.

[0054] During implementation, such as Figure 3 and Figure 4 As shown, a hopper gate 11 for backfilling ballast is provided on one side of the ballast hopper body 1;

[0055] The portion between the ballast removal device 3 and the bucket gate 11 on the top opening of the ballast storage bucket body 1 serves as the ballast cleaning opening 13, and the portion between the ballast removal device and the bucket gate 11 on the opposite side serves as the new ballast filling opening 12.

[0056] The length direction of the ballast removal chain 35 is consistent with the arrangement direction of the new ballast inlet 12 and the clean ballast inlet 13.

[0057] Specifically, the new ballast inlet 12 is used to pour new ballast into the ballast storage bucket 1. During the railway track bed cleaning and screening operation, the vibrating screening device will screen the dirty track ballast dug by the excavation device, and pour the clean ballast that meets the standards into the ballast storage bucket 1 through the clean ballast inlet to prepare for the subsequent backfilling operation.

[0058] By setting a gate 11 on one side of the ballast storage bucket body 1, rationally planning the positions of the ballast cleaning opening and the new ballast filling opening, and ensuring that the length direction of the ballast removal chain is consistent with the arrangement direction of the ballast cleaning opening and the new ballast filling opening, the efficiency, operational flexibility and accuracy of ballast management and processing are significantly improved. At the same time, it also supports a more efficient continuous operation process and enhances the adaptability and reliability of the equipment.

[0059] During implementation, such as Figure 3 and Figure 4 As shown, a backfilling opening 15 is provided on one side of the ballast storage bucket body 1 where the bucket door 11 is located;

[0060] The hopper gate 11 is hinged to the outside of the backfill opening. The hopper gate 11 can be rotated to open and expose the backfill opening, and can be rotated to close the backfill opening 15.

[0061] During implementation, such as Figure 3 and Figure 4 As shown, the length direction of the floor conveyor belt 2 is consistent with the length direction of the ballast chain 35;

[0062] The positive conveying direction of the floor conveyor belt 2 is:

[0063] From the opposite side of the sluice gate 11 toward the sluice gate 11;

[0064] The reverse conveying direction of the floor conveyor belt 2 is:

[0065] From the direction of the sluice gate 11 to the opposite side of the sluice gate 11.

[0066] like Figure 3 As shown, ballast is dropped from the replenishment ballast inlet 12. When the ballast reaches a certain height, the floor conveyor belt 2 slowly rotates in the forward direction, controlling the belt speed according to the amount of ballast dropped, to try to fill the ballast storage hopper as much as possible. The conveyor belt must stop when the ballast reaches the backfill inlet; otherwise, ballast will drop from the backfill inlet. At this point, a large portion of the ballast storage hopper is not full. Especially when the replenishment ballast inlet is too small, the capacity of the ballast storage hopper cannot be fully utilized.

[0067] During ballast storage, the floor conveyor belt can remain stationary or operate normally.

[0068] When the ballast reaches a certain height, the ballast shoveling device can fill the ballast hopper to the maximum extent. If the ballast is stored at too low a height, the ballast shoveling device cannot reach the ballast and therefore does not need to operate.

[0069] When backfilling ballast, the sluice gate 11 is opened, and the floor conveyor belt moves in the positive direction of the floor conveyor belt 2 to backfill the ballast.

[0070] like Figure 4 As shown, ballast is dropped from the ballast inlet 13. When the ballast reaches a certain height, the floor conveyor belt 2 slowly rotates in the opposite direction, controlling the belt speed according to the amount of ballast dropped, trying to fill the ballast storage hopper as much as possible. When the ballast reaches the lower left part of the storage hopper, the floor conveyor belt 2 must stop, otherwise ballast will jam and damage the floor conveyor belt 2. At this time, a considerable portion of the storage hopper is not full. Especially when the ballast inlet is too small, the capacity of the storage hopper cannot be fully utilized.

[0071] To ensure sufficient ballast storage capacity, the floor conveyor belt must continue moving the ballast after it reaches the lower left of the storage hopper. If the ballast inlet is too small, the capacity on both sides of the storage hopper cannot be fully utilized.

[0072] During ballast storage, the floor conveyor belt remains stationary.

[0073] When the ballast reaches a certain height, the ballast shoveling device can fill the ballast hopper to the maximum extent. If the ballast is stored at too low a height, the ballast shoveling device cannot reach the ballast and therefore does not need to operate.

[0074] By using the ballast removal device, the ballast can be filled to the maximum extent possible in the ballast storage bin.

[0075] When backfilling ballast, the sluice gate 11 is opened, and the floor conveyor belt 2 moves in the opposite direction to backfill the ballast.

[0076] During implementation, such as Figure 3 and Figure 4 As shown, the ballast storage hopper also includes:

[0077] A gate actuator 14 with precise control is connected to the gate 11.

[0078] The gate actuator 14 is used to open and close the gate 11.
