Description

Technical Field

[0001] This invention belongs to the field of distribution vehicle technology, and more specifically, relates to a distribution vehicle cleaning system and a storage tank distribution vehicle assembly. Background Technology

[0002] In the tobacco industry, distribution vehicles are generally used as the main conveying equipment for tobacco shreds. Distribution vehicles can orderly distribute tobacco shreds, and have advantages such as precise distribution positioning and fast conveying speed. Existing distribution vehicles need to be maintained and repaired in a timely manner after use, especially during the maintenance process, it is particularly important to clean the tobacco shreds in a timely manner to avoid the breeding of tobacco insects due to cleaning dead spots.

[0003] Because there are many maintenance points on the distribution vehicle, especially when there is tobacco in the storage cabinet, using gas to clean and maintain it can easily lead to hidden dangers such as material cross-contamination. Therefore, at present, only manual wiping and maintenance can be used. This method is not only time-consuming, but also easily creates maintenance dead corners in the narrow spaces between cabinets and on the side of the loading and unloading conveyor belts, which can lead to the breeding of tobacco insects and affect the quality of tobacco production in the later stage. At the same time, the above operation also poses certain safety hazards to workers. Summary of the Invention

[0004] The purpose of this invention is to provide a distribution vehicle cleaning system and a storage tank distribution vehicle assembly, which can conveniently collect tobacco, avoid cleaning dead spots, and improve the safety of cleaning operations.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a distribution vehicle cleaning system is provided, including a collection bin, a support frame, and a receiving tray. The collection bin is connected to the bottom of the distribution vehicle, and a sealing door assembly for sealing the bottom opening of the collection bin is connected to the bottom of the collection bin. The support frame is set below the distribution vehicle track, and the receiving tray is connected to the support frame through a lifting module. A suction pipe is connected to the bottom of the receiving tray.

[0006] When the collection bin moves above the receiving plate following the distribution vehicle, the lifting module can move the receiving plate up to connect with the lower opening of the collection bin.

[0007] In one possible implementation, several collection bins are spaced apart along the direction of the loading and unloading conveyor belts. A support frame is provided with a transverse module arranged parallel to the direction of the loading and unloading conveyor belts. A lifting module is connected to the transverse moving end of the transverse module. The lifting end of the lifting module is connected to an elastic compensation mechanism for adjusting the receiving plate so that the receiving plate is aligned and connected with the collection bin. The receiving plate is connected above the elastic compensation mechanism.

[0008] In one possible implementation, a limiting ring seat is connected to the bottom of the collection compartment. The limiting ring seat is located on the outer periphery of the sealing assembly. The elastic compensation mechanism includes a lower support plate, several sets of elastic telescopic rods, and an upper support plate. The lower support plate is connected to the upper part of the support base. The lower end of the elastic telescopic rods is hinged to the lower support plate. The upper support plate is connected to the upper part of the several sets of elastic telescopic rods and is hinged to each of the several sets of elastic telescopic rods. The receiving plate is fixedly connected to the upper part of the upper support plate. The limiting ring seat has a downward-opening, annularly arranged mounting groove. A guide surface is provided on the outer side wall of the mounting groove. Several limiting rollers for rolling cooperation with the guide surface are provided on the outer periphery of the upper support plate.

[0009] When the lifting module drives the receiving plate to move upward, the limiting roller can move upward with the upper support plate and roll in cooperation with the outer peripheral wall of the limiting ring seat. The elastic telescopic rod group can elastically extend and retract to make the receiving plate and the lower opening of the collection bin aligned and connected.

[0010] In one possible implementation, the sealing assembly includes a fixed plate connected to the lower opening of the collection bin and several rotating blades rotatably connected to the bottom of the fixed plate. The fixed plate has a material drop hole that runs vertically through the center, and the rotating blades are rotatably connected to the bottom of the fixed plate via a connecting shaft.

[0011] The limiting ring seat is rotatably connected to the upper outer periphery of the fixed plate, and the lower support plate is rotatably connected to the upper part of the support. A drive assembly is also provided between the support and the lower support plate. The drive assembly is used to drive the elastic compensation mechanism and the receiving plate to rotate circumferentially. The upper support plate is provided with several pushers for pushing the limiting ring seat to rotate circumferentially to open the rotating blade.

[0012] In one possible implementation, the rotating blade is provided with an upwardly extending limiting post, the fixed plate is provided with a first guide groove that runs vertically through and extends outward in an arc shape, and the limiting ring seat is provided with a radially extending second guide groove. The limiting post is arranged to pass through the first guide groove and the second guide groove in sequence. When the limiting ring seat rotates circumferentially, the limiting post can drive the rotating blade to open the material discharge hole under the limiting guidance of the first guide groove and the second guide groove.

[0013] In one possible implementation, the bottom of the fixing plate is provided with a bottom groove, the rotating blade is disposed in the bottom groove, the bottom groove has a first mating surface that gradually extends outward and downward, and the outer periphery of the receiving plate is provided with a second mating surface that gradually extends inward and upward. The second mating surface can move upward with the receiving plate to abut against the first mating surface so that the receiving plate and the fixing plate are sealed together.

[0014] In some embodiments, the bottom of the limiting ring seat is provided with a circumferentially extending and gradually downward extending push arc surface, and the push member is an opening and closing roller disposed on the outer periphery of the upper support plate. The opening and closing roller can push the push arc surface upward to make the limiting ring seat rotate circumferentially and make the rotating blade open the material dropping hole.

[0015] The bottom of the collection chamber is equipped with an elastic reset member connected to the limiting ring seat. The elastic reset member extends tangentially along the limiting ring seat and can elastically pull back the limiting ring seat to close the material discharge hole of the rotating blade.

[0016] In one possible implementation, a mounting hole is provided through the support, and a track ring is provided inside the mounting hole. Several rotating rollers are rotatably connected to the lower support plate, and the outer peripheral wall of the rotating rollers rolls in cooperation with the inner ring of the track ring.

[0017] In one possible implementation, there are three elastic telescopic rod groups. Each elastic telescopic rod group includes two adjacent elastic telescopic rods that are respectively hinged to the lower support plate. The lower ends of the two elastic telescopic rods in the same elastic telescopic rod group are adjacent to each other. The upper ends of the two adjacent elastic telescopic rods in two adjacent elastic telescopic rod groups extend obliquely to the adjacent side and are respectively hinged to the bottom of the upper support plate.

[0018] Compared with the prior art, the solution shown in this application embodiment uses the collection bin at the bottom of the loading and unloading conveyor belt to collect the tobacco falling from above. The receiving plate on the support frame can move upward under the drive of the lifting module and connect with the bottom opening of the collection bin, which facilitates the concentrated suction of the tobacco in the collection bin under the action of the suction pipe, thereby improving the collection efficiency of tobacco and having a good cleaning effect.

[0019] The present invention also provides a storage tank distribution vehicle assembly, which includes a distribution vehicle and a distribution vehicle cleaning system. The distribution vehicle includes a distribution vehicle track, a loading and unloading conveyor belt that is rolled on the distribution vehicle track, and a limiting frame that is set above the loading and unloading conveyor belt. The two sides of the loading and unloading conveyor belt are respectively provided with traveling rollers that roll in cooperation with the distribution vehicle track. The traveling rollers are covered with protective covers. The protective covers include wheel cover frames connected to the side wall of the limiting frame and opening doors hinged to the outside of the wheel cover frames. The two sides of the wheel cover frames are respectively rotatably connected to limiting swing arms. The two limiting swing arms can swing vertically towards each other until they abut against the periphery of the opening door to lock the opening door.

[0020] The aforementioned storage and distribution vehicle assembly utilizes the rolling of loading and unloading belts along the distribution vehicle track to transfer tobacco shreds. The operation of the loading and unloading belts effectively receives and unloads the tobacco shreds within the limiting frame. The collection bin below the loading and unloading belts can collect the tobacco shreds falling from above. The receiving plate on the support frame can move upward under the drive of the lifting module and connect with the lower opening of the collection bin, facilitating the concentrated suction of the tobacco shreds in the collection bin by the suction pipe. This improves the collection efficiency of tobacco shreds, has a good cleaning effect, and ensures safety during the production process. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0040] Please refer to the following: Figures 1 to 14 The present invention will now describe the cleaning system for the distribution vehicle and the storage tank distribution vehicle assembly. The cleaning system for the distribution vehicle includes a collection compartment 3, a support frame 4, and a receiving tray 5. The collection compartment 3 is connected to the bottom of the distribution vehicle, and a sealing assembly 6 for sealing the lower opening of the collection compartment 3 is connected to the bottom of the collection compartment 3. The support frame 4 is located below the distribution vehicle track 11. The receiving tray 5 is connected to the support frame 4 via a lifting module 81, and a suction pipe 41 is connected to the bottom of the receiving tray 5. When the collection compartment 3 moves with the distribution vehicle to above the receiving tray, the lifting module 81 can drive the receiving tray 5 to move up to connect with the lower opening of the collection compartment 3.

[0041] Compared with the prior art, the distribution vehicle cleaning system provided in this embodiment uses the collection bin 3 at the bottom of the loading and unloading conveyor belt 1 to collect the tobacco falling from above. The receiving plate 5 on the support frame 4 can move upward under the drive of the lifting module 81 and connect with the lower opening of the collection bin 3, so that the tobacco in the collection bin 3 can be concentrated and sucked out under the suction action of the suction pipe 41, which improves the collection efficiency of tobacco, has a good cleaning effect, and ensures the safety of the production process.

[0042] It should be noted that the distribution vehicle can roll along the distribution vehicle track 11. The distribution vehicle mainly includes an unloading conveyor belt 1 and a limiting frame 2. The unloading conveyor belt 1 includes a frame 13 and a belt 12 rotatably connected to the frame 13. The limiting frame 2 is a rectangular frame structure that runs vertically through the belt. The limiting frame 2 is fixedly connected to the frame 13 through a connecting frame 21. The limiting frame 2 is located above the belt 12. The lower edges of the side plates on both sides of the limiting frame 2 are pressed against the belt 12 by a pressure belt 27 made of flexible material. The end plates at both ends of the limiting frame 2 protrude outward from the belt 12, leaving space for the unloading of the belt 12. The frame 13 is provided with traveling rollers 22 on both sides that can roll along the distribution vehicle track 11. The collection bin 3 is connected to the frame 13 and located below the belt 12. The support frame 4 and the receiving plate 5 are located at a fixed position below the distribution vehicle track 11.

[0043] Specifically, the frame 13 is a rectangular frame structure that runs vertically through the frame, and the end plates at both ends of the frame 13 are aligned vertically with the end plates at both ends of the limiting frame 2. The collection chamber 3 is bolted to the frame 13 and is located below the belt 12.

[0044] When the distribution vehicle rolls along the distribution vehicle track 11, the tobacco on the loading and unloading conveyor belt 1 and the collection bin 3 can move synchronously. When the loading and unloading conveyor belt 1 moves to the position where the collection bin 3 and the receiving plate 5 correspond vertically, under the action of the suction pipe 41, the tobacco can sequentially pass through the collection bin 3 and the middle of the receiving plate 5 and enter the suction pipe 41, realizing the centralized collection of tobacco.

[0045] In use, the distribution vehicle moves along the distribution vehicle track 11 to the receiving position. The upper unloading component feeds the tobacco into the cavity formed by the limiting frame 2 and the belt body 12. At this time, the limiting frame 2 remains stationary, while the belt body 12 moves to distribute the tobacco shreds within the horizontally positioned internal space of the limiting frame 2. After feeding is completed, the distribution vehicle moves along the distribution vehicle track 11 to the unloading position. At this time, the belt body 12 moves to unload the tobacco shreds from the limiting frame 2 into the storage tank, completing the unloading process.

[0046] There is some tobacco leakage in the narrow area between the two sides of the belt 12 and the frame 13, and there is also some tobacco adhering to the belt 12. The collection chamber 3 can collect the tobacco using the collection holes on the top. Specifically, the top wall of the collection chamber 3 can be made of an air distribution plate, and the collection holes are the holes on the air distribution plate. The air distribution plate can make the airflow of the suction pipe 41 evenly distributed, thereby enhancing the tobacco collection effect.

[0047] During use, tobacco shreds adhering to the belt 12 and those in the gaps on both sides of the belt 12 will fall into the collection chamber 3 for collection. When the collection chamber 3 moves horizontally with the frame 13 above the receiving plate 5, the receiving plate 5 moves upward under the action of the lifting module 81 to connect with the collection chamber 3. Under the suction force of the suction pipe 41, the tobacco shreds are sucked away by the suction pipe 41 through the receiving plate 5. The above structure realizes the effective collection of tobacco shreds from different positions on the distribution vehicle, improves cleaning efficiency, and ensures safety during the cleaning process.

[0048] Specifically, the suction pipe 41 is a flexible vacuum pipe, and its outer end is connected to a vacuum dust removal fan. The vacuum dust removal fan can use a 7.5Kw motor, with a wind force of up to 1.7Kpa and an air volume of up to 5268m³. 3 / h, to meet the suction capacity requirements of suction pipe 41. The selection of vacuum dust removal fan is not limited to the above parameters, but should be based on meeting the specific requirements of tobacco suction function.

[0049] In one possible implementation, please refer to Figures 1 to 14 The collection bins 3 are spaced apart along the direction of the loading and unloading conveyor belt 1. The support frame 4 is provided with a transverse module 82 that is parallel to the direction of the loading and unloading conveyor belt 1. The lifting module 81 is connected to the transverse end of the transverse module 82. The lifting end of the lifting module 81 is connected to an elastic compensation mechanism 7 for adjusting the receiving plate 5 so that the receiving plate 5 is aligned and connected with the collection bin 3. The receiving plate 5 is connected above the elastic compensation mechanism 7.

[0050] In this embodiment, since the limiting frame 2 extends a long distance along the length of the belt, while the size of the receiving plate 5 below is limited in the corresponding direction, the collection bins 3 are set in multiple forms. Multiple collection bins 3 are spaced apart along the direction of the loading and unloading belt conveyor 1. The lifting module 81 is used to lift the receiving plate 5 upward to achieve effective alignment with different collection bins 3, thereby performing a suction action on different positions within the limiting frame 2 to remove tobacco shreds.

[0051] At the same time, the lifting end of the lifting module 81 is also equipped with a horizontal module 82. The horizontal position of the receiving plate 5 is adjusted by the horizontal moving end of the horizontal module 82 to ensure that the receiving plate 5 is effectively aligned with the lower opening of the upper collection chamber 3, and to ensure that the suction pipe 41 has a good suction cleaning effect.

[0052] Based on the above structure, the lower opening of the collection chamber 3 adopts a tubular structure, with the inner cavity of the tubular body forming the lower opening of the collection chamber 3. To ensure effective connection between the receiving plate 5 and the lower opening of the collection chamber 3, the posture of the receiving plate 5 is adjusted by an elastic compensation mechanism 7. This allows the receiving plate 5 to passively move with arbitrary degrees of freedom in space, until the center of the receiving plate 5 and the lower opening of the collection chamber 3 are aligned and their end faces are flush. This avoids the problem of ineffective connection between the surface of the receiving plate 5 and the end face of the lower opening of the collection chamber 3. At least one adjustable frequency vibrator 36 is provided on the bottom wall of the collection chamber 3. The vibrator 36 can drive the collection chamber 3 to vibrate, conveying the material inside the collection chamber 3 to the lower opening position.

[0053] In addition, four steel plates are welded to the ground below the support frame 4. Threaded holes are pre-drilled in the center of the steel plates. Anchor bolts are provided at the four corners of the bottom of the support frame 4. The anchor bolts are connected to the threaded holes of the steel plates to facilitate the installation and connection of the support frame 4.

[0054] In one possible implementation, please refer to Figures 1 to 14 The bottom of the collection chamber 3 is connected to a limiting ring seat 31, which is located on the outer periphery of the sealing assembly 6. The elastic compensation mechanism 7 includes a lower support plate 71, several sets of elastic telescopic rods 73, and an upper support plate 76. The lower support plate 71 is connected to the upper part of the support 44. The lower end of the elastic telescopic rods 73 is hinged to the lower support plate 71. The upper support plate 76 is connected to the upper part of the several sets of elastic telescopic rods 73 and is hinged to the several sets of elastic telescopic rods 73 respectively. The receiving plate 5 is fixedly connected to the upper part of the upper support plate 76. The limiting ring seat 31 has an installation groove 32 with an opening facing downward and arranged in a ring shape. The outer side wall of the installation groove 32 is provided with a guide surface 33. The outer periphery of the upper support plate 76 is provided with several limiting rollers 51 for rolling cooperation with the guide surface 33.

[0055] When the lifting module 81 drives the receiving plate 5 to move upward, the limiting roller 51 can move upward with the upper support plate 76 and roll in cooperation with the guide surface 33. The elastic telescopic rod group 73 can elastically extend and retract to make the receiving plate 5 aligned with the lower opening of the collection chamber 3.

[0056] In this embodiment, during the process of the lifting module 81 driving the receiving plate 5 to move up and down, the limiting roller 51 on the outer periphery of the receiving plate 5 can form a rolling engagement relationship with the guide surface 33, ensuring the alignment effect between the receiving plate 5 and the limiting ring seat 31 during the rising process, thereby improving the sealing of the subsequent connection between the two and ensuring the suction function of the suction pipe 41.

[0057] Specifically, three limiting rollers 51 are spaced apart on the outer periphery of the receiving plate 5, with adjacent limiting rollers 51 set at a 120° angle to ensure effective limiting with the guide surface 33 and improve positioning accuracy.

[0058] Based on the above structure, the posture of the receiving plate 5 is adjusted by the elastic compensation mechanism 7, so that the upper support plate 76 and the receiving plate 5 can move in any degree of freedom in space by relying on the elastic telescopic rod group 73 until the receiving plate 5 and the lower center of the collection chamber 3 are aligned and the end faces are aligned, which means that it will be aligned and connected with the fixed plate 61 in the future.

[0059] In one possible implementation, the sealing assembly 6 includes a fixed plate 61 connected to the lower opening of the collection bin 3 and several rotating blades 62 rotatably connected to the bottom of the fixed plate 61. The fixed plate 61 has a material drop hole 63 that runs vertically through the center, and the rotating blades 62 are rotatably connected to the bottom of the fixed plate 61 via a connecting shaft 64.

[0060] The limiting ring seat 31 is rotatably connected to the upper outer periphery of the fixed plate 61, and the lower support plate 71 is rotatably connected to the upper part of the support 44. A drive assembly 72 is also provided between the support 44 and the lower support plate 71. The drive assembly 72 is used to drive the elastic compensation mechanism 7 and the receiving plate 5 to rotate circumferentially. The upper support plate 76 is provided with several pushers for pushing the limiting ring seat 31 to rotate circumferentially to open the rotating blade 62.

[0061] In this embodiment, the sealing assembly 6 adopts a combination of a fixed plate 61 and multiple rotating blades 62. The fixed plate 61 is provided with a material discharge hole 63 that is aligned vertically with the lower opening of the collection bin 3. The material discharge hole 63 is blocked by multiple rotating blades 62 that are rotatably connected to the bottom of the fixed plate 61.

[0062] In one possible implementation, the rotating blade 62 is provided with an upwardly extending limiting post 65, the fixing plate 61 is provided with a first guide groove 66 that runs vertically through and extends outward in an arc shape, and the limiting ring seat 31 is provided with a radially extending second guide groove 37. The limiting post 65 is arranged to pass through the first guide groove 66 and the second guide groove 37 in sequence. When the limiting ring seat 31 rotates circumferentially, the limiting post 65 can drive the rotating blade 62 to open the material discharge hole 63 under the limiting guidance of the first guide groove 66 and the second guide groove 37.

[0063] In some embodiments, please refer to Figures 1 to 14 The bottom of the fixing plate 61 is provided with a bottom groove 67, and the rotating blade 62 is disposed in the bottom groove 67. The bottom groove 67 has a first mating surface 68 that gradually extends outward and downward. The outer periphery of the receiving plate 5 is provided with a second mating surface 53 that gradually extends inward and upward. The second mating surface 53 can move upward with the receiving plate 5 to abut against the first mating surface 68 so that the receiving plate 5 and the fixing plate 61 are sealed together.

[0064] In this embodiment, the material discharge hole 63 is connected vertically to the lower opening of the collection bin 3. The guide surface 33 of the bottom groove 67 can guide the limiting roller 51 from bottom to top, so that when the lifting module 81 moves the receiving plate 5 upward, it can accurately align the receiving plate 5 with the fixing plate 61, thereby ensuring the effective alignment of the lower suction pipe 41 with the material discharge hole 63.

[0065] Based on this, the effective fit between the first mating surface 68 on the bottom groove 67 and the second mating surface 53 on the receiving plate 5 is utilized. Both have inclined peripheral walls. Under the drive of the lifting module 81, they can gradually approach and fit together, avoiding the problem of gaps between the receiving plate 5 and the fixed plate 61, thereby ensuring the suction effect of the suction tube 41 on the tobacco in the collection chamber 3.

[0066] In some embodiments, please refer to Figures 1 to 14 The bottom of the limiting ring seat 31 is provided with a circumferentially extending and gradually downward extending push arc surface 35. The push component is an opening and closing roller 52 set on the outer periphery of the upper support plate 76. The opening and closing roller 52 can push the push arc surface 35 upward to make the limiting ring seat 31 rotate circumferentially and make the rotating blade 62 open the material dropping hole 63.

[0067] The bottom of the collection chamber 3 is provided with an elastic reset member 34 connected to the limiting ring seat 31. The elastic reset member 34 extends tangentially along the limiting ring seat 31 and can elastically pull back the limiting ring seat 31 so that the rotating blade 62 closes the material drop hole 63.

[0068] In this embodiment, when the pushing arc surface 35 of the limiting ring seat 31 is pushed by the opening and closing roller 52, the limiting post 65 on the rotating blade 62 can rotate horizontally around its own connecting shaft 64 under the dual guidance of the first guide groove 66 and the second guide groove 37, and rotate to open towards the outer periphery of the discharge hole 63, so that the discharge hole 63 is effectively connected to the suction pipe 41 below, thereby realizing the driving effect on the rotating blade 62, which facilitates the effective opening of the lower opening of the collection chamber 3 and meets the collection needs of tobacco.

[0069] When the above structure operates, the horizontal module 82 first drives the elastic compensation mechanism 7 and the receiving plate 5 to move laterally so that the lower opening of the collection chamber 3 (i.e., the fixed plate 61) roughly aligns with the receiving plate 5. Then, the drive assembly 72 drives the lower support plate 71, the elastic telescopic rod assembly 73, and the receiving plate 5 to rotate synchronously in the circumferential direction so that the opening and closing roller 52 and the arc surface of the pushing arc surface 35 correspond and fit together one by one. Then, the lifting module 81 drives the elastic compensation mechanism 7 and the receiving plate 5 to move upward, so that the upper support plate 76 and the receiving plate 5 passively undergo arbitrary spatial freedom of movement based on the elastic telescopic rod assembly 73, until the center of the receiving plate 5 and the lower opening of the collection chamber 3 (i.e., the fixed plate 61) are aligned and the end faces are aligned. After that, when the elastic telescopic rod assembly 73 is gradually compressed to its limit, the elastic telescopic rod 74 locks, and the upper support plate 76 and the receiving plate 5 lock and remain stationary.

[0070] At this time, the opening and closing roller 52 contacts the pushing arc surface 35 at the bottom of the limiting ring seat 31. As the opening and closing roller 52 continues to rise, it presses the pushing arc surface 35 in the forward direction. The separation of the forward pressing force in the horizontal direction drives the limiting ring seat 31 to rotate. At this time, the limiting post 65 on the rotating blade 62 is affected by the position change of the first guide groove 66, and rotates around the connecting shaft 64 under the constraint of the second guide groove 37, so that the rotating blade 62 is opened externally, so that the dropping hole 63 is connected from top to bottom, making it easier for the tobacco to fall into the tray 5 or the suction pipe 41 below.

[0071] Specifically, there are three opening and closing rollers 52. The three opening and closing rollers 52 are arranged at intervals along the outer periphery of the receiving plate 5. The two adjacent opening and closing rollers 52 are arranged at an angle of 120°. The opening and closing rollers 52 and the limiting rollers 51 are arranged at intervals in the circumference of the receiving plate 5, which facilitates spatial arrangement.

[0072] In one possible implementation, a mounting hole 42 is provided through the support 44, and a track ring 43 is provided in the mounting hole 42. Several rotating rollers 75 are rotatably connected to the lower support plate 71, and the outer peripheral wall of the rotating rollers 75 rolls in cooperation with the inner ring of the track ring 43.

[0073] In this embodiment, the rotating roller 75 is limited by the track ring 43 located above the support 44, and the rotation direction of the lower support plate 71 is effectively limited by the cooperation between the rotating roller 75 and the track ring 43. The drive assembly 72 adopts a structure in which the motor drives the lead screw, and the lead screw drives the slider to slide. The bottom of the slider is provided with a rotating shaft rotatably connected to the lower support plate 71. The bottom of the motor is provided with a turntable. The output shaft of the motor drives the lead screw to rotate. While the slider moves along the axial direction of the lead screw, it drives the lower support plate 71, the elastic telescopic rod assembly 73 and the receiving plate 5 to rotate synchronously, which has a stable driving effect.

[0074] Furthermore, the lower support plate 71 is provided with an installation groove extending radially along the track ring 43. The rotating roller 75 is installed in a suitable position in the installation groove through a connector, which facilitates the adjustment of the relative position of the rotating roller 75 and the track ring 43 and improves the convenience of installation.

[0075] In one possible implementation, there are three elastic telescopic rod groups 73. Each elastic telescopic rod group 73 includes two adjacent elastic telescopic rods 74 that are respectively hinged to the lower support plate 71. The lower ends of the two elastic telescopic rods 74 in the same elastic telescopic rod group 73 are adjacent to each other. The upper ends of the two adjacent elastic telescopic rods 74 in two adjacent elastic telescopic rod groups 73 extend obliquely to the adjacent side and are respectively hinged to the bottom of the upper support plate 76.

[0076] In this embodiment, the elastic telescopic rod group 73 is provided in three groups. Each elastic telescopic rod group 73 includes two elastic telescopic rods 74 that gradually move away from each other from bottom to top. In two adjacent elastic telescopic rod groups 73, two close elastic telescopic rods 74 gradually move closer from bottom to top, forming multiple approximately triangular support structures between the upper support plate 76 and the lower support plate 71, ensuring the elastic support effect on the upper receiving plate 5.

[0077] Specifically, each elastic telescopic rod 74 has the following structure: it includes an upward-opening sleeve and a telescopic rod slidably connected within the sleeve. The sleeve contains an elastic element for elastically pushing the telescopic rod upwards. When the receiving plate 5 moves upwards to contact the limiting ring seat 31, the elastic element is gradually compressed until it reaches its compression limit, which can be set to 20mm. At this point, the receiving plate 5 adjusts its position and posture to ensure a tight seal with the limiting ring seat 31, guaranteeing a sealed connection between the two.

[0078] Based on the same inventive concept, this application also provides a storage tank distribution vehicle assembly, which includes a distribution vehicle and a distribution vehicle cleaning system. The distribution vehicle includes a distribution vehicle track 11, a loading and unloading conveyor belt 1 that is rolled on the distribution vehicle track 11, and a limiting frame 2 that is set above the loading and unloading conveyor belt 1. The loading and unloading conveyor belt 1 is provided with two traveling rollers 22 that roll in cooperation with the distribution vehicle track 11 on both sides. The traveling rollers 22 are covered with protective covers 23. The protective covers 23 include wheel cover frames 24 connected to the side wall of the limiting frame 2 and an opening door 25 hinged to the outside of the wheel cover frames 24. The two sides of the wheel cover frames 24 are rotatably connected to limiting swing arms 26. The two limiting swing arms 26 can swing vertically towards each other until they abut against the periphery of the opening door 25 to lock the opening door 25.

[0079] The aforementioned storage and distribution vehicle assembly utilizes the rolling of the loading and unloading conveyor belt 1 along the distribution vehicle track 11 to transfer tobacco shreds. The operation of the loading and unloading conveyor belt 1 enables the effective reception and unloading of tobacco shreds within the limiting frame 2. The collection bin 3 below the loading and unloading conveyor belt 1 can collect the tobacco shreds falling from above. The receiving plate 5 on the support frame 4 can move upward under the drive of the lifting module 81 and connect with the lower opening of the collection bin 3, facilitating the concentrated suction of the tobacco shreds in the collection bin 3 by the suction action of the suction pipe 41. This improves the collection efficiency of tobacco shreds, has a good cleaning effect, and ensures safety during the production process.

[0080] In this embodiment, several traveling rollers 22 are provided on both sides of the loading and unloading conveyor belt 1 for traveling along the distribution vehicle track 11. The protective cover 23 has a streamlined structure and can cover the outside of the traveling rollers 22, forming a good protective effect. The protective cover 23 has a simple structure and is easy to install. It mainly includes two hinged wheel cover frames 24 and an opening door 25. The wheel cover frames 24 are fixed to the outside of the limiting frame 2 by bolts. Both the wheel cover frames 24 and the opening door are arc-shaped cover structures that protect the traveling rollers 22 inside. The shape and size are consistent with the wheel size.

[0081] The opening door 25 is made of lightweight material and is fixed to the outside of the wheel cover frame 24 by a pivot or hinge. The pivot or hinge is located at the top of the wheel cover frame 24, allowing for flexible opening and closing. After the door is closed, it is limited by two limiting arms 26. The limiting arms 26 are rotatably connected to the outside of the wheel cover frame 24, with their main shafts perpendicular to the direction of the belt body 12. By allowing the limiting arms 26 to swing vertically to engage with the outer edge of the upper part of the opening door, the door is prevented from opening automatically when the traveling rollers 22 roll, ensuring the locking effect of the door and facilitating the maintenance and cleaning of internal components such as the traveling rollers 22. This structural design is not only aesthetically pleasing and practical but also simplifies the cleaning, repair, and maintenance of the traveling rollers 22, thus avoiding the cumbersome process of disassembly.

[0082] In use, the horizontal module 82 drives the elastic compensation mechanism 7 and the receiving plate 5 to move laterally so that the receiving plate 5 roughly corresponds to the fixed plate 61. Then, the drive assembly 72 drives the lower support plate 71, the elastic telescopic rod assembly 73 and the receiving plate 5 to rotate synchronously in the circumferential direction so that the opening and closing roller 52 corresponds and fits one-to-one with the arc surface of the pushing arc surface 35, and is close to the lower part of the arc surface of the pushing arc surface 35.

[0083] The lifting module 81 drives the elastic compensation mechanism 7 and the receiving plate 5 to move upward. The limiting roller 51 first contacts the guide surface 33 of the bottom groove 67 of the fixed plate 61, so that the upper support plate 76 and the receiving plate 5 can move freely in space by means of the elastic telescopic rod group 73 until the receiving plate 5 and the fixed plate 61 are aligned at the center and at the end.

[0084] As the lifting module group 81 continues to drive the upper support plate 76 and the receiving plate 5 to rise, the elastic telescopic rod group 73 is gradually compressed to its limit. At this time, the elastic telescopic rod 74 is locked, and the upper support plate 76 and the receiving plate 5 are locked and do not move.

[0085] At this time, the opening and closing roller 52 contacts the pushing arc surface 35 at the bottom of the limiting ring seat 31. As the opening and closing roller 52 continues to rise, it exerts positive pressure on the pushing arc surface 35. The separation of the positive pressure in the horizontal direction drives the limiting ring seat 31 to rotate, which in turn drives multiple rotating blades 62 to rotate and open synchronously in the outward direction, so that the suction pipe 41 and the collection chamber 3 can be effectively connected. At the same time, the cooperation of the first mating surface 68 and the second mating surface 53 ensures the tight sealing between the fixing plate 61 and the receiving plate 5, so that a sealed vacuum adsorption area is formed between the collection chamber 3 and the suction pipe 41, which ensures the suction function of the suction pipe 41, improves the cleaning effect on the distribution vehicle, and improves the convenience of operation.

[0086] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
