Description

Technical Field

[0001] This application belongs to the field of waste material cleaning technology, and particularly relates to a waste material cleaning device for a carriage. Background Technology

[0002] Currently, rail transport, as a clean mode of transportation, is widely used in material transport, such as transporting coal in the steel and coal-fired power generation sectors, and transporting ore in metal smelting. After the train transports the materials to the designated location, unloading devices such as tippers are generally used to unload the materials from the wagons. A large amount of residual material remains in the wagons after unloading. Therefore, it is necessary to clean up the remaining material in the wagons to avoid resource waste.

[0003] In related technologies, a cargo compartment cleaning device is typically used to clean up the remaining material inside the cargo compartment. However, the failure rate and cost of such cargo compartment cleaning devices are relatively high. Summary of the Invention

[0004] In view of this, the present application provides a carriage waste cleaning device to solve the technical problems of high failure rate and high cost of carriage waste cleaning devices in the related art.

[0005] This application provides a vehicle compartment waste material cleaning device, including a support frame, a first lifting mechanism, a cleaning mechanism, a second lifting mechanism, and a discharging mechanism.

[0006] The vehicle compartment waste material cleaning device has a cleaning state and a discharging state. When the vehicle compartment waste material cleaning device is in the cleaning state, the second lifting mechanism drives the discharging mechanism to rise above the vehicle compartment, and the first lifting mechanism drives the cleaning mechanism to descend into the vehicle compartment to clean the waste material. The vehicle compartment moves forward or backward in its direction of travel so that the cleaning mechanism gathers the waste material at the side door of the vehicle compartment. When the vehicle compartment waste material cleaning device is in the discharging state, the first lifting mechanism drives the cleaning mechanism to rise above the vehicle compartment, and the vehicle compartment moves forward or backward in its direction of travel so that the discharging mechanism is above the waste material. The second lifting mechanism drives the discharging mechanism to descend into the vehicle compartment to move the waste material so that the waste material is removed from the side door of the vehicle compartment.

[0007] The waste material cleaning device for a freight car according to this application embodiment cleans the waste material inside the freight car by first lowering the discharge mechanism into the freight car via a first lifting mechanism, causing the freight car to move forward or backward in its direction of travel, thus accumulating the cleaned waste material. Then, a second lifting mechanism lowers the discharge mechanism into the freight car to remove the accumulated waste material. This waste material cleaning device, by coordinating with the movement of the freight car, completes the cleaning of waste material inside the freight car. It only requires the cleaning mechanism and the discharge mechanism to move up and down, simplifying the mechanical structure of the waste material cleaning device, thereby reducing the failure rate, decreasing the size of the device, and lowering costs.

[0066] To address the high failure rate and cost of existing cargo compartment scrap cleaning devices, the inventors have discovered that the reason lies in the following: Car cargo compartment scrap cleaning devices typically include a support mechanism, a cleaning disc, and a drive mechanism. The cleaning disc is connected to the support mechanism via the drive mechanism. The drive mechanism drives the cleaning disc to clean the scrap material inside the cargo compartment. However, to achieve comprehensive cleaning of the cargo compartment, existing scrap cleaning devices require the cleaning disc to have three mutually perpendicular degrees of freedom, making the structure of the support and drive mechanisms complex. This results in a high failure rate and increases the size and cost of the scrap cleaning device.

[0067] In view of this, this application provides a vehicle cargo compartment scrap cleaning device, which includes a first lifting mechanism, a second lifting mechanism, a cleaning mechanism, and a discharging mechanism. The first lifting mechanism is connected to the cleaning mechanism, and the second lifting mechanism is connected to the discharging mechanism. When cleaning the scrap material inside the vehicle compartment, firstly, the first lifting mechanism lowers the discharging mechanism into the compartment, causing the compartment to move forward or backward in its direction of travel, causing the cleaned scrap material to accumulate. Then, the second lifting mechanism lowers the discharging mechanism into the compartment to remove the accumulated scrap material. This vehicle cargo compartment scrap cleaning device, by coordinating with the movement of the vehicle compartment, completes the cleaning of the scrap material inside the compartment. It only requires the cleaning mechanism and the discharging mechanism to move up and down, simplifying the mechanical mechanism of the vehicle cargo compartment scrap cleaning device, thereby reducing the failure rate, and also reducing the size and cost of the device.

[0068] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0069] It should be noted that the direction of travel, lateral movement, and vertical movement of the carriage described in the embodiments of this application are as follows: Figure 1 and Figure 2 The directions x, y, and z are shown.

[0070] refer to Figure 1 and Figure 2This application provides a vehicle compartment waste material cleaning device, including a support frame 10, a first lifting mechanism 20, a cleaning mechanism 30, a second lifting mechanism 40, and a discharge mechanism 50. The support frame 10 is mounted on a vehicle compartment 70. The first lifting mechanism 20 is connected to the support frame 10. The cleaning mechanism 30 is connected to the first lifting mechanism 20 and configured to clean the waste material inside the vehicle compartment 70. The second lifting mechanism 40 is connected to the support frame 10 and spaced apart from the first lifting mechanism 20. The discharge mechanism 50 is connected to the second lifting mechanism 40 and configured to move the waste material inside the vehicle compartment 70.

[0071] The waste material cleaning device for the carriage has a cleaning state and a discharging state. When the waste material cleaning device is in the cleaning state, the second lifting mechanism 40 drives the discharging mechanism 50 to rise above the carriage 70, and the first lifting mechanism 20 drives the cleaning mechanism 30 to descend into the carriage 70 to clean the waste material. The carriage 70 moves forward or backward in its direction of travel so that the cleaning mechanism 30 gathers the waste material at the side door of the carriage 70. When the waste material cleaning device is in the discharging state, the first lifting mechanism 20 drives the cleaning mechanism 30 to rise above the carriage 70, and the carriage 70 moves forward or backward in its direction of travel so that the discharging mechanism 50 is positioned above the waste material. The second lifting mechanism 40 drives the discharging mechanism 50 to descend into the carriage 70 to move the waste material and remove it from the side door of the carriage.

[0072] The waste material cleaning device for the carriage 70 of this application embodiment cleans the waste material inside the carriage 70 by first lowering the discharge mechanism 50 into the carriage 70 via the first lifting mechanism 20, and causing the carriage 70 to move forward or backward in its traveling direction, causing the cleaned waste material to accumulate. Then, the discharge mechanism 50 is lowered into the carriage 70 via the second lifting mechanism 40 to remove the accumulated waste material from the carriage. The waste material cleaning device for the carriage of this application embodiment completes the cleaning of waste material inside the carriage 70 through the coordinated movement of the discharge mechanism 50 and the carriage 70. Only the cleaning mechanism 30 and the discharge mechanism 50 need to be raised and lowered, which simplifies the mechanical structure of the waste material cleaning device, thereby reducing the failure rate, reducing the size of the waste material cleaning device, and reducing costs.

[0073] The support frame 10 provides support for other components of the cargo compartment scrap cleaning device. For example, refer to... Figure 1 The support frame 10 may include a main frame 110, a first frame 120, and a second frame 130. The main frame 110 may be a three-dimensional frame. For example, the main frame 110 may include two first horizontal beams 111, four first vertical beams 112, and four first vertical beams 113, which together form a three-dimensional frame with an open bottom and sides.

[0074] The bottom of the main frame 110 may also be provided with drive wheels 114 to facilitate the movement of the main frame 110 and other components connected to the main frame 110. For example, when using the car body scrap cleaning device of this application embodiment to transport coal, the drive wheels 114 can move and lock along the existing track of the coal transport port, so that the main frame 110 can be more easily erected on the car body 70, thereby improving the efficiency of installing the support frame 10.

[0075] The first frame 120 and the second frame 130 are both located within the main frame 110 and are both connected to the main frame 110. The first frame 120 is used to connect the first lifting mechanism 20. Exemplarily, the first frame 120 may include a second crossbeam 121 and two second vertical beams 122, the second crossbeam 121 and the second vertical beams 122 forming a portal frame. The second frame 130 is used to connect the second lifting mechanism 40. Exemplarily, the second frame 130 may include a third crossbeam 131 and two third vertical beams 132, the third crossbeam 131 and the third vertical beams 132 forming a portal frame.

[0076] For example, the main frame 110, the first frame 120, and the second frame 130 can all be made of steel to give the support frame 10 greater strength. It is understood that the main frame 110, the first frame 120, and the second frame 130 can also be made of other materials, which will not be described in detail in this embodiment.

[0077] The support frame 10 may also include an equipment platform 140, which can be connected to the side of the main frame 110. The equipment platform 140 is used to support the electrical equipment of the carriage waste cleaning device, such as the control room 60.

[0078] The first lifting mechanism 20 is connected to the support frame 10 and to the sweeping mechanism 30, thereby driving the sweeping mechanism 30 to lift and lower. For example, refer to... Figure 1 and Figure 3The first lifting mechanism 20 may include a lifting drive assembly 210, a connecting beam 220, two transmission screws 230, and two transmission nuts 240. The lifting drive assembly 210 is mounted on the main frame 110. For example, the lifting drive assembly 210 may be connected to the second crossbeam 121 of the first frame 120. Both transmission screws 230 are vertically arranged and spaced laterally. The top end of each transmission screw 230 is connected to the lifting drive assembly 210 to rotate under its drive. Two transmission nuts 240 are respectively fitted onto the two transmission screws 230. The connecting beam 220 is arranged laterally and connects the two transmission nuts 240. The connecting beam 220 connects to the cleaning mechanism 30. When the lifting drive assembly 210 operates, it drives the two transmission screws 230 to rotate, causing the two transmission nuts 240 to slide on the two transmission screws 230 respectively, thereby driving the connecting beam 220 and the cleaning mechanism 30 to rise and fall. The connecting beam 220 is raised and lowered by two drive screws 230 and two drive nuts 240, which can improve the stability of the connecting beam 220 during the raising and lowering process, thereby improving the stability of the sweeping mechanism 30 during the raising and lowering process.

[0079] In some possible implementations of this application, the lifting drive assembly 210 may include two lifting drive motors, both mounted on the support frame 10. The output shaft of one lifting drive motor is connected to the top end of a transmission screw 230. The output shaft of the other lifting drive motor is connected to the top end of another transmission screw 230. When the cleaning mechanism 30 is raised or lowered, the output shafts of the two lifting drive motors can be controlled to rotate synchronously, and the output shafts of the two lifting drive motors respectively drive the connecting beam 220 and the cleaning mechanism 30 to rise or fall.

[0080] In some other possible implementations of the embodiments of this application, reference is made to Figure 3 The lifting drive assembly 210 may include a dual-axis motor 211, two mechanical commutators 212, and two drive rods 213. Both output shafts of the dual-axis motor 211 are arranged laterally. For example, refer to... Figure 1 The support frame 10 may have two first vertical through holes 123 spaced laterally. For example, the first vertical through holes 123 may be provided on the second crossbeam 121 of the first frame 120. The two first vertical through holes 123 are respectively for the two transmission screws 230 to pass through. Two mechanical commutators 212 are installed on the support frame 10 spaced laterally. Each mechanical commutator 212 has a rotary input end and a rotary output end with mutually perpendicular axes. The rotary input ends of the two mechanical commutators 212 are respectively connected to the two output shafts of the dual-axis motor 211 through the transmission rod 213. The rotary output ends of the two mechanical commutators 212 face the two first vertical through holes 123 and are connected to the top of the transmission screws 230.

[0081] When the two output shafts of the dual-axis motor 211 rotate, they drive two mechanical commutators 212 via a transmission rod 213, which in turn drive two lead screws 230 to rotate. Since the two output shafts of the dual-axis motor 211 can rotate synchronously, the synchronicity of the rotation of the two lead screws 230 is improved, thereby enhancing the smoothness of the lifting and lowering of the connecting beam 220 and the cleaning mechanism 30, and reducing the control difficulty of the lifting drive assembly 210.

[0082] For example, both ends of the connecting beam 220 may be provided with a third vertical through hole, and the axis of the transmission nut 240 may coincide with the axis of the third vertical through hole, so that the transmission screw 230 can pass through the second vertical through hole, and interference between the transmission screw 230 and the connecting beam 220 can be avoided when the cleaning mechanism 30 is raised and lowered.

[0083] A connecting plate 221 can be provided at the bottom end of the connecting beam 220. The diameter of the connecting plate 221 can be greater than the width of the connecting beam 220 along the travel direction of the carriage 70, so that the connecting plate 221 has a sufficiently large area to connect with the cleaning mechanism 30, thereby increasing the connection strength between the connecting beam 220 and the cleaning mechanism 30.

[0084] For example, refer to Figure 2 and Figure 3 Guide wheels 222 can also be provided at both ends of the connecting beam 220. The axes of both guide wheels 222 are set along the traveling direction of the carriage 70. A vertical guide rail 124 can be provided on the side of the support frame 10 facing the first lifting mechanism 20. For example, the guide rail 124 can be connected to the second vertical beam 122 of the first frame 120. The guide wheels 222 can roll on the guide rail 124, thereby guiding the connecting beam 220 and further improving the stability of the connecting beam 220 and the cleaning mechanism 30 during lifting.

[0085] For example, the bottom end of the guide rail 124 may also be provided with a limiting part 125, which can limit the connecting beam 220 to prevent the connecting beam 220 from being too low and causing the transmission nut 240 to slip off the transmission screw 230.

[0086] The cleaning mechanism 30 is connected to the first lifting mechanism 20 and can move up and down under the action of the first lifting mechanism 20. For example, refer to... Figure 4The cleaning mechanism 30 may include a first mounting frame 310, multiple cleaning drive motors 320, multiple cleaning drive shafts 330, and multiple cleaning discs 340. The first mounting frame 310 is connected to the first lifting mechanism 20. For example, the first mounting frame 310 can be connected to the connecting disc 221 of the connecting beam 220 via a connecting column 311. The first mounting frame 310 may be provided with multiple second vertical through holes 312, which are arranged at intervals along the lateral direction. The multiple cleaning drive motors 320 are arranged one-to-one with the multiple second vertical through holes 312, and the output shaft of each cleaning drive motor 320 faces the corresponding second vertical through hole 312. The multiple cleaning drive shafts 330 are arranged one-to-one with the multiple second vertical through holes 312, and each cleaning drive shaft 330 passes through the corresponding second vertical through hole 312. The top end of each cleaning drive shaft 330 is connected to the output shaft of the cleaning drive motor 320. Multiple sweeping discs 340 are configured one-to-one with multiple sweeping drive shafts 330, with each sweeping disc 340 connected to the bottom end of its corresponding sweeping drive shaft 330. When the output shaft of the sweeping drive motor 320 rotates, it can drive the sweeping discs 340 to rotate through the sweeping drive shafts 330, thereby cleaning the remaining material inside the carriage 70.

[0087] For example, refer to Figure 5 The sweeping mechanism 30 may further include a first baffle assembly 350 and a second baffle assembly 360 connected to the first mounting bracket 310. The first baffle assembly 350 and the second baffle assembly 360 are respectively disposed on both sides of the sweeping disc 340 along the travel direction of the carriage 70. Both the first baffle assembly 350 and the second baffle assembly 360 are configured to block residual material swept by the sweeping disc 340, so that the residual material accumulates. Below, we assume that along the travel direction of the carriage 70, the first baffle assembly 350 is located in front of the second baffle assembly 360, i.e.... Figure 4 Taking the example of the first material blocking component 350 located on the left side of the cleaning disc 340 and the second material blocking component 360 located on the right side of the cleaning disc 340, the working process of the first material blocking component 350 and the second material blocking component 360 will be explained.

[0088] During the cleaning of residual material inside the carriage 70, the carriage 70 can move forward in its direction of travel. When the first lifting mechanism 20 drives the cleaning mechanism 30 to descend into the carriage 70, the cleaning mechanism can approach the rear end of the carriage 70. Then, the first material blocking component 350 can be controlled to be in a non-blocking state so as not to block the residual material. And the second material blocking component 360 can be controlled to be in a blocking state to block the residual material. Subsequently, the cleaning drive motor 320 drives the cleaning disc 340 to rotate, and the carriage 70 moves backward in its direction of travel. The second material blocking component 360 blocks the residual material cleaned by the cleaning disc 340 and pushes the residual material from the rear end of the carriage 70 to the front end of the carriage 70.

[0089] During the cleaning of residual material inside the carriage 70, the carriage 70 can also reverse along its direction of travel. When the first lifting mechanism 20 lowers the cleaning mechanism 30 into the carriage 70, the cleaning mechanism can approach the front end of the carriage 70. Then, the first material blocking component 350 can be controlled to be in a blocking state to block the residual material. The second material blocking component 360 can be controlled to be in a non-blocking state to not block the residual material. Subsequently, the cleaning drive motor 320 drives the cleaning disc 340 to rotate, and the carriage 70 moves forward along its direction of travel. The first material blocking component 350 blocks the residual material cleaned by the cleaning disc 340 and pushes the residual material from the front end to the rear end of the carriage 70.

[0090] Accordingly, when cleaning the remaining material inside the carriage 70, the first baffle assembly 350 and the second baffle assembly 360 can be controlled to be in a blocking or non-blocking state, and in coordination with the moving direction of the carriage 70, so that the remaining material cleaned by the cleaning disc 340 can move within the carriage 70, thereby adjusting the position of the remaining material so that it can accumulate at the side door of the carriage 70, so that the subsequent discharge mechanism 50 can remove the remaining material from the side door of the carriage 70. Compared with the related technology, which uses a dust suction device to suck up the remaining material located on the floor of the carriage 70, changes the height of the remaining material in the vertical direction, and does work on the remaining material in the vertical direction, the carriage remaining material cleaning device of this application embodiment can change the position of the remaining material inside the carriage 70 and do work on the remaining material in the horizontal direction. The work done is less, thereby reducing the energy consumption of the carriage remaining material cleaning device.

[0091] For example, refer to Figure 4 The first baffle assembly 350 may include a first baffle 351, a gear 352, a rack 353, and a baffle drive motor. The first baffle 351 is slidably connected to the first mounting bracket 310 in a vertical direction. For example, the first mounting bracket 310 has a vertically arranged first slide rail 313 on the side facing the first baffle 351. A first slider 354 is connected to the side of the first baffle 351 facing the first mounting bracket 310, and the first slider 354 slides on the first slide rail 313. The first mounting bracket 310 and the first baffle 351 are slidably connected by the cooperating first slide rail 313 and first slider 354. The baffle drive motor is mounted on the side of the first mounting bracket 310 facing the first baffle 351, and the output shaft of the baffle drive motor is arranged in a horizontal direction. The gear 352 is sleeved on the output shaft of the baffle drive motor. The rack 353 is vertically mounted on the side of the first baffle 351 facing the first mounting bracket 310 and meshes with the gear 352.

[0092] The first material blocking assembly 350 has a blocking state and a non-blocking state. When the first material blocking assembly 350 is in the blocking state, the material blocking drive motor drives the gear 352 to rotate, and the gear 352 pushes the rack 353 to move vertically downward, thereby causing the first baffle 351 to move towards the bottom plate of the carriage 70, so as to reduce the distance between the first baffle 351 and the bottom plate of the carriage 70 and block the excess material. When the carriage 70 moves, the first baffle 351 can push the excess material to move. When the first material blocking assembly 350 is in the non-blocking state, the material blocking drive motor drives the gear 352 to rotate in the opposite direction, and the gear 352 pushes the rack 353 to move vertically upward, thereby causing the first baffle 351 to move away from the bottom plate of the carriage 70, so as to increase the distance between the first baffle 351 and the bottom plate of the carriage 70 and not block the excess material.

[0093] For example, the end of the first baffle 351 facing the floor of the carriage 70 may be covered with rubber to prevent the first baffle 351 from damaging the floor of the carriage 70 when the carriage 70 moves.

[0094] For example, a detection sensing element, such as a proximity switch or a laser rangefinder, may be provided at the end of the first baffle 351 facing the floor of the carriage 70 to detect the position of the first baffle 351. When the first baffle 351 descends to a certain height, the detection sensing element sends a position signal. After receiving the position signal, the control room 60 controls the first lifting mechanism 20 to stop descending, thereby automatically stopping the cleaning mechanism 30 when it descends, so as to realize the automatic control of the carriage waste cleaning device.

[0095] The structure of the second baffle assembly 360 can be similar to that of the first baffle assembly 350. For details, please refer to the above description of the structure and working process of the first baffle assembly 350. This application embodiment will not repeat the details.

[0096] The second lifting mechanism 40 is connected to the support frame 10 and is spaced apart from the first lifting mechanism 20. The second lifting mechanism 40 is connected to the discharge mechanism 50 to drive the discharge mechanism 50 to lift. Exemplarily, the structure of the second lifting mechanism 40 can be the same as that of the first lifting mechanism 20, except that the lifting drive component 210 in the second lifting mechanism 40 is connected to the third crossbeam 131 of the second frame 130. Furthermore, the connecting beam 220 in the second lifting mechanism 40 is connected to the discharge mechanism 50. For details, please refer to the above description of the structure and working process of the first lifting mechanism 20; this embodiment will not repeat the details here.

[0097] The discharge mechanism 50 is connected to the second lifting mechanism 40 and is used to remove the accumulated surplus material from the side door of the carriage 70. For example, refer to... Figure 5 and Figure 6The discharge mechanism 50 may include a mounting plate 510, a discharge assembly 520, and a discharge drive cylinder 530. The mounting plate 510 is connected to the second lifting mechanism 40. For example, the mounting plate 510 may be connected to the connecting beam 220 of the second lifting mechanism 40 via a connecting bracket 513. The discharge assembly 520 is slidably connected to the mounting plate 510 in a transverse direction to push the accumulated residual material. The discharge drive cylinder 530 is mounted on the mounting plate 510 and connected to the discharge assembly 520 to drive the discharge assembly 520 to slide relative to the mounting plate 510.

[0098] After the surplus material accumulates at the side door of the carriage 70, the first lifting mechanism 20 drives the cleaning mechanism 30 to rise above the carriage 70. The carriage 70 moves forward or backward in its direction of travel so that the discharge mechanism 50 is positioned above the surplus material. The second lifting mechanism 40 drives the discharge mechanism 50 to descend into the carriage 70. The discharge drive cylinder 530 drives the discharge assembly 520 to slide laterally relative to the mounting plate 510, thereby removing the surplus material from the carriage 70 through the side door of the carriage 70.

[0099] For example, a second slide rail 511 arranged laterally is installed below the mounting plate 510, and a second slider 521 is connected to the side of the discharge assembly 520 facing the mounting plate 510. The second slider 521 slides on the second slide rail 511. The mounting plate 510 is provided with a clearance through hole 512, through which a portion of the discharge assembly 520 passes. A discharge drive cylinder 530 can be installed on the mounting plate 510, for example, on the top surface of the mounting plate 510. The discharge drive cylinder 530 is connected to a portion of the discharge assembly 520 passing through the clearance through hole 512, thereby driving the discharge assembly 520 to slide laterally relative to the mounting plate 510.

[0100] For example, refer to Figure 6 There can be two discharge components 520, both of which are laterally slidably connected to the mounting plate 510. There can also be two discharge drive cylinders 530, each connected to one of the two discharge components 520 to drive the two discharge components 520 to slide relative to the mounting plate 510. For example, the two discharge components 520 can be driven in opposite directions, which can remove accumulated waste material from the side doors on both sides of the carriage 70, improving the efficiency of waste material cleaning.

[0101] refer to Figure 7 and Figure 8The discharge assembly 520 may include a second mounting bracket 522, two support plates 523, a discharge roller brush 524, and a roller brush drive motor 525. The second mounting bracket 522 is laterally slidably connected to the mounting plate 510; for example, the second mounting bracket 522 may be connected to the second slider 521. Part of the second mounting bracket 522 may pass through the clearance hole 512 and be connected to the drive cylinder 530. The two support plates 523 are respectively disposed on both sides of the second mounting bracket 522 along the traveling direction of the carriage 70, and the first ends of both support plates 523 are connected to the second mounting bracket 522. The discharge roller brush 524 is located between the two support plates 523, and both ends of the discharge roller brush 524 are rotatably connected to the second ends of the two support plates 523, respectively. The roller brush drive motor 525 is mounted on the second mounting bracket 522 and connected to one end of the discharge roller brush 524 to drive the discharge roller brush 524 to rotate, thereby enabling the discharge roller brush 524 to remove accumulated excess material.

[0102] For example, refer to Figure 7 The second mounting bracket 522 may include a connecting portion 5221 and a receiving portion 5222. A first end of the connecting portion 5221 can be connected to the second slider 521, and a second end of the connecting portion 5221 is connected to the receiving portion 5222. The receiving portion 5222 has a receiving space. The roller brush drive motor 525 can be housed within the receiving space of the receiving portion 5222 and is fixedly connected to the receiving portion 5222. The output shaft of the roller brush drive motor 525 can extend out of the receiving portion 5222 and is rotatably connected to the receiving portion 5222 via a rolling bearing. In some possible implementations of this application embodiment, the output shaft of the roller brush drive motor 525 may be connected to a connecting shaft, and the connecting shaft is rotatably connected to the receiving portion 5222 via a rolling bearing.

[0103] Two support plates 523 are respectively disposed on both sides of the receiving part 5222 along the traveling direction of the carriage 70. The first end of the two support plates 523 is connected to the receiving part 5222, and the second end of the two support plates 523 is connected to the discharge roller brush 524.

[0104] The discharge roller brush 524 may include a discharge shaft 5241 located between two support plates 523 and a plurality of discharge push plates 5242. Both ends of the discharge shaft 5241 are rotatably connected to the second ends of the two support plates 523, respectively. For example, each of the second ends of the two support plates 523 is provided with a rotating through hole, and both ends of the discharge shaft 5241 are inserted into the rotating through hole. One end of the discharge shaft 5241 can be connected to the output shaft of the roller brush drive motor 525. The plurality of discharge push plates 5242 are circumferentially spaced around the discharge shaft 5241, and one side of each discharge push plate 5242 is connected to the discharge shaft 5241, for example, by welding. When the roller brush drive motor 525 drives the discharge shaft 5241 to rotate, the discharge shaft 5241 drives the plurality of discharge push plates 5242 to rotate, and the plurality of discharge push plates 5242 sequentially push the remaining material to move, thereby realizing the removal of the remaining material.

[0105] The discharge mechanism 50 may further include a roller brush drive assembly 540, through which the discharge shaft 5241 and the output shaft of the roller brush drive motor 525 can be connected. Exemplarily, the roller brush drive assembly 540 may include a drive wheel 541, a driven wheel 542, and a drive belt 543. The drive wheel 541 is sleeved on the output shaft of the roller brush drive motor 525. The driven wheel 542 is sleeved on the discharge shaft 5241 of the discharge roller brush 524. The drive belt 543 surrounds the drive wheel 541 and the driven wheel 542 and meshes with them. When the output shaft of the roller brush drive motor 525 rotates, it drives the drive wheel 541 to rotate. The drive wheel 541 drives the driven wheel 542 to rotate via the drive belt 543, thereby driving the discharge shaft 5241 of the discharge roller brush 524 to rotate, so that the multiple discharge push plates 5242 of the discharge roller brush 524 push the remaining material. By setting the roller brush drive assembly 540, the position of the roller brush drive motor 525 can be adjusted, thereby optimizing the mechanical structure of the discharge mechanism 50.

[0106] For example, the driving pulley 541 can be a main synchronous belt pulley, the driven pulley 542 can be a driven synchronous belt pulley, and the transmission belt 543 can be a synchronous belt. Alternatively, the driving pulley 541 can be a driving sprocket, the driven pulley 542 can be a driven sprocket, and the transmission belt 543 can be a chain. In some possible implementations of this application's embodiments, the roller brush transmission assembly 540 can also be a gear transmission assembly, which will not be elaborated further in this application's embodiments.

[0107] For example, a second baffle 526 may also be provided on the discharge roller brush 524. When the multiple discharge push plates 5242 push the residual material, the second baffle 526 can block the residual material to prevent the residual material carried by the discharge push plates 5242 from accumulating on the side opposite to the direction of the discharge roller brush 524, thereby ensuring the effect of removing the residual material. For example, the second baffle 526 can be an arc-shaped baffle, which is provided above the multiple discharge push plates 5242 and has a gap between it and the discharge push plates 5242. The two ends of the arc-shaped baffle are respectively connected to two support plates 523.

[0108] refer to Figure 7 and Figure 8 The first ends of both support plates 523 are rotatable relative to the second mounting bracket. For example, the first end of one support plate 523 may be rotatably connected to the receiving portion 5222 of the second mounting bracket 522 via a rotating shaft. The first end of the other support plate 523 may be provided with a connecting through hole, which is sleeved on the output shaft of the roller brush drive motor 525 or a connecting shaft connected to the output shaft of the roller brush drive motor 525. The discharge mechanism 50 may also include a lifting drive cylinder 550, the first end of which is rotatably connected to the second mounting bracket 522 about the traveling direction of the carriage 70, and the second end of which is rotatably connected to the support plate 523 about the traveling direction of the carriage 70. For example, the support plate 523 has a protrusion 5231 extending toward the lifting drive cylinder 550. A support shaft 5232 connects the protrusions 5231 of the two support plates 523. One end of the lifting drive cylinder 550 is rotatably connected to the support shaft 5232.

[0109] The lifting drive cylinder 550 can drive two support plates 523 to rotate relative to the second mounting frame 522 via the support shaft 5232. The two support plates 523 drive the discharge roller brush 524 to rotate relative to the second mounting frame 522, thereby controlling the discharge roller brush 524 to be raised or lowered, and precisely adjusting the height of the discharge roller brush 524, thus improving the positional accuracy of the discharge roller brush 524.

[0110] refer to Figure 5 and Figure 6 The discharge mechanism 50 may further include two third baffles 560, which are respectively disposed on both sides of the discharge assembly 520 along the traveling direction of the carriage 70, and both third baffles 560 are connected to the mounting plate 510. When the discharge assembly 520 removes excess material, the two third baffles 560 can block the excess material, preventing it from overflowing to both sides of the discharge assembly 520 and affecting the removal effect.

[0111] For example, the end of the third baffle 560 facing the floor of the carriage 70 may be covered with rubber to prevent the third baffle 560 from damaging the floor of the carriage 70.

[0112] For example, a detection sensing element, such as a proximity switch or a laser rangefinder, may be provided at the end of the third baffle 560 facing the floor of the carriage 70 to detect the position of the third baffle 560. When the third baffle 560 descends to a certain height, the detection sensing element sends a position signal. After receiving the position signal, the control room 60 controls the second lifting mechanism 40 to stop descending, thereby automatically stopping the descent of the discharge mechanism 50.

[0113] To facilitate understanding of the technical solutions in the embodiments of this application, the following description takes the side door of the carriage 70 located in the middle of the carriage as an example, and describes the process of cleaning up leftover materials in detail with reference to the specific structure of the carriage leftover material cleaning device. It is understood that the side door of the carriage 70 can also be located in other positions of the carriage 70, such as near the front or rear end of the carriage, which will not be elaborated in the embodiments of this application.

[0114] First, gather the remaining material inside carriage 70 at the side door of carriage 70.

[0115] The support frame 10 is erected directly above the carriage 70. For example, the support frame 10 can be moved along an existing track such as a coal port to the travel track of the carriage 70, the carriage 70 can be moved along the travel track of the carriage 70 to directly below the support frame 10 by a traction vehicle, and the position of the support frame 10 can be adjusted and fixed.

[0116] The traction vehicle moves the carriage 70 forward in its direction of travel, bringing the sweeping mechanism 30 closer to the rear end of the carriage 70. The sweeping mechanism 30 is then lowered, and the discharge mechanism 50 is raised. For example, in the first lifting mechanism 20, the two output shafts of the dual-axis motor 211 rotate synchronously. Each output shaft drives a mechanical commutator 212 via a transmission rod 213, which in turn drives two transmission screws 230 to rotate. This causes two transmission nuts 240 to descend relative to the two transmission screws 230. The two transmission nuts 240, through the connecting beam 220, lower the sweeping mechanism 30 into the carriage 70 and closer to the rear end of the carriage 70. In the second lifting mechanism 40, the two output shafts of the dual-axis motor 211 rotate synchronously in opposite directions. The two output shafts of the dual-axis motor 211 drive the two mechanical commutators 212 through the transmission rod 213, thereby driving the two transmission screws 230 to rotate in opposite directions. This causes the two transmission nuts 240 to rise relative to the two transmission screws 230. The two transmission nuts 240 drive the discharge mechanism 50 to rise above the carriage 70 through the connecting beam 220.

[0117] Adjust the first baffle assembly 350 and the second baffle assembly 360 so that the first baffle assembly 350 is in a non-baffle state and the second baffle assembly 360 is in a baffle state, and cause the cleaning mechanism 30 to clean and collect the remaining coal. For example, the output shaft of the baffle drive motor in the first baffle assembly 350 rotates, driving the gear 352 to rotate. The gear 352 pushes the rack 353 upward, and the rack 353 drives the first baffle 351 upward, so that the first baffle 351 of the first baffle assembly 350 does not block the remaining material. In the second baffle assembly 360, the output shaft of the baffle drive motor rotates in the opposite direction, driving the gear 352 to rotate in the opposite direction. The gear 352 pushes the rack 353 downward, and the rack 353 drives the first baffle 351 downward, so that the first baffle 351 of the second baffle assembly 360 blocks the remaining material. In the sweeping mechanism 30, the sweeping drive motor 320 drives the sweeping disc 340 to rotate via the sweeping transmission shaft 330 to sweep away residual coal. The traction vehicle moves the carriage 70 backward in its direction of travel. The first baffle 351 of the second baffle assembly 360 blocks the residual material swept by the sweeping disc 340 and applies a pushing force to the material, causing it to move from the rear end of the carriage 70 towards the middle. The residual material is then collected at the side door in the middle of the carriage 70. The sweeping drive motor 320 then stops.

[0118] The sweeping mechanism 30 is raised, and the traction vehicle moves the carriage 70 backward in its direction of travel, bringing the sweeping mechanism 30 closer to the front end of the carriage 70, and then lowers the sweeping mechanism 30. Exemplarily, in the first lifting mechanism 20, the two output shafts of the dual-axis motor 211 rotate synchronously in opposite directions. Each output shaft drives a mechanical commutator 212 via a transmission rod 213, thereby causing two transmission screws 230 to rotate in opposite directions. This causes two transmission nuts 240 to rise relative to the two transmission screws 230, and the two transmission nuts 240, through the connecting beam 220, raise the sweeping mechanism 30 above the remaining material. The traction vehicle continues to move the carriage 70 backward in its direction of travel, bringing the sweeping mechanism 30 closer to the front end of the carriage 70, and the first lifting mechanism 20 controls the sweeping mechanism 30 to descend.

[0119] The first baffle assembly 350 and the second baffle assembly 360 are readjusted so that the first baffle assembly 350 is in the baffle state and the second baffle assembly 360 is in the non-baffle state, and the cleaning mechanism 30 cleans and collects the remaining coal again. For example, the output shaft of the baffle drive motor in the first baffle assembly 350 rotates in the reverse direction, driving the gear 352 to rotate in the reverse direction. The gear 352 pushes the rack 353 downward, and the rack 353 drives the first baffle 351 downward, thus blocking the remaining material. In the second baffle assembly 360, the output shaft of the baffle drive motor rotates, driving the gear 352 to rotate. The gear 352 pushes the rack 353 upward, and the rack 353 drives the first baffle 351 upward, thus preventing the first baffle 351 from blocking the remaining material.

[0120] The tractor drives the carriage 70 forward in its direction of travel. The first baffle 351 of the first baffle assembly 350 blocks the residual material swept by the sweeping disc 340 and applies a pushing force to the residual material, causing it to move from the front end of the carriage 70 to the middle end. The residual material is then collected at the side door in the middle of the carriage 70. The sweeping drive motor 320 is then paused.

[0121] Then, the accumulated leftover material is removed from the side door of carriage 70.

[0122] The traction vehicle moves the carriage 70 forward in its direction of travel, positioning the discharge mechanism 50 above the remaining material at the side door of the carriage 70. The discharge mechanism 50 is lowered, and the cleaning mechanism 30 is raised. For example, in the second lifting mechanism 40, the two output shafts of the dual-axis motor 211 rotate synchronously. Each output shaft drives a mechanical commutator 212 via a transmission rod 213, thereby rotating two transmission screws 230. This causes two transmission nuts 240 to descend relative to the two transmission screws 230. The two transmission nuts 240, through the connecting beam 220, lower the discharge mechanism 50 above the remaining material accumulated at the side door of the carriage 70. In the first lifting mechanism 20, the two output shafts of the dual-axis motor 211 rotate synchronously in opposite directions. The two output shafts of the dual-axis motor 211 drive the two mechanical commutators 212 to work through the transmission rod 213, thereby driving the two transmission screws 230 to rotate in opposite directions. This causes the two transmission nuts 240 to rise relative to the two transmission screws 230. The two transmission nuts 240 drive the sweeping mechanism 30 to rise above the carriage 70 through the connecting beam 220.

[0123] The discharge mechanism 50 removes the accumulated waste material from the side door of the carriage 70. Exemplarily, two third baffles 560 of the discharge mechanism 50 are located on either side of the accumulated waste material to block it. The output shaft of the roller brush drive motor 525 rotates, driving the discharge shaft 5241 to rotate, which in turn drives multiple discharge push plates 5242 to rotate. Simultaneously, the discharge drive cylinder 530 drives the discharge assembly 520 to move laterally, causing the multiple discharge push plates 5242 to sequentially push the accumulated waste material, thus removing it from the side door of the carriage 70.

[0124] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
