The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0032] Please also read Figures 1 to 11 , the self-cleaning tobacco collection system of the distribution vehicle and the tobacco distribution vehicle assembly provided by the utility model are now described. The self-cleaning tobacco collection system of the distribution vehicle comprises a collection bin 1, a support frame 2 and a receiving plate 3, the collection bin 1 is connected to the bottom of the distribution vehicle, the support frame 2 is arranged below the distribution vehicle track 9, the receiving plate 3 is arranged on the support frame 2, a collection hole 11 is arranged on the top surface of the collection bin 1, a sliding door 4 for blocking the lower opening of the collection bin 1 is slidably connected to the bottom of the collection bin 1, a lifting drive member 21 for driving the receiving plate 3 to move up and down is arranged on the support frame 2, and a suction pipe 31 is connected below the receiving plate 3;

[0033] The collecting bin 1 can follow the distribution vehicle to move above the receiving tray 3 , and the receiving tray 3 can move upward driven by the lifting drive 21 and communicate with the collecting bin 1 to suck the collecting bin 1 with the help of the suction pipe 31 .

[0034] The self-cleaning tobacco collection system for the distribution vehicle provided in the present embodiment is compared with the prior art. The self-cleaning tobacco collection system for the distribution vehicle provided in the present embodiment can collect the tobacco dropped from the distribution vehicle in a centralized manner by arranging a collection bin 1 under the distribution vehicle. The receiving tray 3 is connected to the suction tube 31. After the collection bin 1 moves to above the receiving tray 3, the sliding door 4 is opened. Under the suction action of the suction tube 31, the tobacco in the collection bin 1 falls into the receiving tray 3 and is sucked away by the suction tube 31, thereby realizing the effective collection of tobacco. The above structure can effectively remove tobacco, eliminate the hidden dangers of tobacco insects, and is conducive to improving production efficiency.

[0035] It should be noted that the distribution vehicle can roll along the distribution vehicle track 9. The distribution vehicle mainly includes a loading and unloading belt conveyor 7 and a limiting frame 8. The loading and unloading belt conveyor 7 includes a frame 72 and a belt body 71 rotatably connected to the frame 72. The limiting frame 8 is a rectangular frame structure that runs through from top to bottom. The limiting frame 8 is fixedly connected to the frame 72 through a connecting frame 81. The limiting frame 8 is located above the belt body 71. The lower edges of the side plates on both sides of the limiting frame 8 are pressed against the belt body 71 by a belt pressing belt 84 made of a flexible material to ensure the smooth operation of the belt body 71. The end plates at both ends of the limiting frame 8 protrude outward from the belt body 71 to leave space for the unloading of the belt body 71. Both sides of the frame 72 are provided with rollers that can roll along the distribution vehicle track 9. The collection bin 1 is connected to the frame 72 and is located below the belt body 71. The support frame 2 and the receiving plate 3 are located at a fixed position below the distribution vehicle track 9.

[0036] The collecting bin 1 is connected to the lower part of the frame 72 by a connecting screw 82, and is arranged correspondingly with the upper limiting frame 8. When the distribution vehicle rolls along the distribution vehicle track 9, the tobacco leaves on the loading and unloading belt conveyor 7 and the collecting bin 1 can move synchronously. When the loading and unloading belt conveyor 7 moves to the upper and lower corresponding positions of the collecting bin 1 and the receiving tray 3, under the action of the suction pipe 31, the tobacco can enter the suction pipe 31 through the collecting bin 1 and the middle part of the receiving tray 3 in sequence, so as to realize the centralized collection of tobacco.

[0037] When in use, the distribution vehicle moves along the distribution vehicle track 9 to the position where the material is received, and the upper material drop component loads the material into the cavity formed by the limit frame 8 and the belt body 71. At this time, the limit frame 8 does not move, and the belt body 71 moves to distribute the tobacco leaves in the internal space of the limit frame 8 in the horizontal direction. After the loading is completed, the distribution vehicle moves along the distribution vehicle track 9 to the position where the material needs to be unloaded. At this time, the belt body 71 moves to unload the tobacco leaves in the limit frame 8 into the storage cabinet, completing the unloading process.

[0038] Tobacco shreds may leak out of the narrow area between the two sides of the belt body 71 and the frame body 72, and tobacco shreds may adhere to the belt body 71. The collecting bin 1 may collect the tobacco shreds with the help of the collecting holes 11 above. Specifically, the top wall of the collecting bin 1 may adopt an air distribution plate, and the collecting holes 11 are holes on the air distribution plate. The air distribution plate may evenly distribute the wind force of the suction pipe 31, thereby enhancing the tobacco shreds collection effect.

[0039] When the collecting bin 1 moves horizontally to the top of the receiving plate 3 following the limiting frame 8, the receiving plate 3 moves upward under the drive of the lifting drive member 21 to connect with the collecting bin 1. Under the suction force of the suction tube 31, the tobacco adhered to the belt body 71 and the tobacco in the gaps on both sides of the belt body 71 can fall into the collecting bin 1 and be sucked away by the suction tube 31 through the middle of the receiving plate 3. The above structure realizes the effective collection of tobacco at different positions of the distribution vehicle, improves the cleaning efficiency, and ensures the safety during the cleaning process.

[0040] In one possible implementation, see Figures 1 to 11 A plurality of collecting bins 1 are arranged at intervals along the extending direction of the limiting frame 8 , and two sliding doors 4 are arranged under each collecting bin 1 , and the two sliding doors 4 are symmetrically arranged on both sides of the central axis of the collecting bin 1 .

[0041] In this embodiment, since the length of the distribution vehicle is relatively large and the size of the receiving tray 3 below is limited in the corresponding direction, the collecting bins 1 are provided in a plurality, and two sliding doors 4 are symmetrically provided below each collecting bin 1. When a certain collecting bin 1 moves to the top of the receiving tray 3, the receiving tray 3 moves upward under the drive of the lifting drive 21 and connects with the bottom wall of the collecting bin 1, and then the two sliding doors 4 move away from each other and open the lower opening of the collecting bin 1 to connect the collecting bin 1 with the receiving tray 3. Under the action of the suction pipe 31, the tobacco shreds at different parts of the distribution vehicle enter the collecting bin 1 and fall into the receiving tray 3 to be smoothly extracted by the suction pipe 31, thereby realizing the rational use of space and reducing the overall cost of the equipment.

[0042] Specifically, the opening of the sliding door 4 can be driven by a hydraulic cylinder. The moving position of the collection bin 1 can be monitored by setting a proximity switch on the receiving plate 3. A marking component for the proximity switch to monitor is set on the collection bin 1. After the proximity switch detects the above-mentioned marking component, it sends a signal to the controller. The controller determines that the collection bin 1 has reached the position corresponding to the upper and lower receiving plate 3 below according to a preset program, and then the controller sends a control instruction to the hydraulic cylinder to drive the sliding door 4 to open. In addition, the sliding door 4 can also be driven by a mechanical structure.

[0043] For some examples, see Figures 1 to 11 A door opening vertical plate 41 is provided at the bottom of the sliding door 4, and the door opening vertical plate 41 extends along the central axis direction of the collecting bin 1. There is an opening gap between the two door opening vertical plates 41 of the same collecting bin 1, and an opening and closing block 5 is provided on the receiving plate 3. When the collecting bin 1 moves with the limiting frame 8, the opening and closing block 5 can enter the opening gap and horizontally push the two door opening vertical plates 41 to separate the two sliding doors 4 from each other.

[0044] In this embodiment, a door opening plate 41 is provided at the bottom of the sliding door 4, and the opening and closing block 5 on the receiving plate 3 is used to push the two door opening plates 41 to realize the separation and opening of the sliding doors 4 on both sides. Specifically, the opening and closing block 5 can be a structure with a pointed end such as a diamond block or a conical block. When the collection bin 1 moves with the limiting frame 8, the pointed end of the opening and closing block 5 can enter the opening gap between the two door opening plates 41 and form a pushing effect on the door opening plates 41, thereby making the sliding doors 4 move away from each other and separate, so as to open the lower opening of the collection bin 1.

[0045] In one possible implementation, see Figures 1 to 11The bottom wall of the collecting bin 1 gradually extends obliquely downwardly from the central axis of the collecting bin 1 . A supporting plate 12 is connected to the bottom of the collecting bin 1 . A mounting groove for mounting the sliding door 4 is formed between the supporting plate 12 and the bottom wall of the collecting bin 1 . An elastic member 13 is provided in the mounting groove for elastically pushing the sliding door 4 toward the central axis side of the collecting bin 1 .

[0046] In this embodiment, the bottom wall of the collecting bin 1 is inclined to facilitate the movement of the tobacco to the lower opening of the collecting bin 1, so that the tobacco can be discharged smoothly. In order to facilitate the installation of the sliding door 4, a supporting plate 12 is provided at the bottom of the collecting bin 1, and a mounting groove is formed between the supporting plate 12 and the bottom wall of the collecting bin 1. At the same time, the sliding door 4 is elastically pushed by the elastic member 13, so that the two sliding doors 4 remain in a closed state.

[0047] For some examples, see Figures 1 to 11 A limiting column 14 extending along the sliding direction of the sliding door 4 is also provided in the installation groove. The elastic member 13 is sleeved on the limiting column 14 and protrudes from the limiting column 14 toward the central axis side of the collecting bin 1. An inner groove 42 is provided on the outer end surface of the sliding door 4. The end of the elastic member 13 extends into the inner groove 42 and abuts against the bottom wall of the inner groove 42.

[0048] In this embodiment, a limiting column 14 is further provided in the installation groove, and the elastic member 13 is sleeved on the outer periphery of the limiting column 14. The limiting column 14 can improve the stability of the axial position of the elastic member 13 and prevent the elastic member 13 from being skewed.

[0049] On this basis, an inner groove 42 is provided on the outer end surface of the sliding door 4 to limit the extended end of the elastic member 13, thereby avoiding positional displacement of the contact portion between the elastic member 13 and the sliding door 4 and ensuring the elastic pushing effect of the elastic member 13 on the sliding door 4.

[0050] For some examples, see Figures 1 to 11 A guide groove 15 is provided through the supporting plate 12 and is arranged along the sliding direction of the sliding door 4 . A guide column 43 extending downward is provided on the sliding door 4 . The guide column 43 is slidably connected in the guide groove 15 .

[0051] In this embodiment, a guide groove 15 is provided on the supporting plate 12, and a guide column 43 extending downward is provided on the sliding door 4. The sliding direction of the sliding door 4 is effectively limited by the sliding cooperation of the guide groove 15 and the guide column 43, so as to avoid the sliding direction of the sliding door 4 being misaligned and causing the position of the sliding door 4 to be stuck.

[0052] Specifically, the sliding door 4 is provided with a mounting hole 44 which passes through from top to bottom, and the mounting hole 44 is used to install the guide column 43. A plurality of guide columns 43 and guide grooves 15 can be provided one by one to ensure a good guiding effect. On the basis of the above effects, the cooperation between the guide grooves 15 and the guide columns 43 can also limit the sliding range of the sliding door 4, thereby improving the smoothness of the sliding process.

[0053] In one possible implementation, see Figures 1 to 11 Vibration assemblies 6 are respectively provided on both sides of the support frame 2, and the vibration assembly 6 includes an articulated frame 61 hinged to the side of the support frame 2, an auxiliary frame 62 hinged to the outer end of the articulated frame 61, an exciter 63 rotatably connected to the outer end of the auxiliary frame 62, and a telescopic driving member 64. The main axis of the exciter 63 is arranged parallel to the central axis of the collecting bin 1, and the outer periphery of the exciter 63 is provided with a tangentially extending bonding plate 65. The lower end of the telescopic driving member 64 is hinged to the support frame 2, and the upper end is hinged to the articulated frame 61. The telescopic driving member 64 is used to drive the articulated frame 61 and the exciter 63 to swing vertically so that the bonding plate 65 contacts the bottom wall of the collecting bin 1.

[0054] In this embodiment, the auxiliary frame 62 is hinged to the side of the support frame 2 through the hinge frame 61, and the telescopic driving member 64 is used to drive the auxiliary frame 62 to swing vertically, thereby adjusting the position of the exciter 63, so that the bonding plate 65 of the exciter 63 contacts the bottom wall of the collecting bin 1, driving the collecting bin 1 to vibrate, thereby facilitating the discharge of tobacco in the collecting bin 1 and improving the discharge efficiency.

[0055] For some examples, see Figures 1 to 11 Two limit rods 66 are hinged on the auxiliary frame 62, which are respectively located on both sides of the exciter 63. The limit rods 66 are rotatably connected to the two sides of the auxiliary frame 62 through the limit plates 67 and extend along the circumference of the exciter 63. The extending end of the limit rod 66 is provided with a connecting portion 68, and the connecting portion 68 is connected to the bonding plate 65 through a hinge 69. The side wall of the auxiliary frame 62 is provided with a limit groove 621 for limiting the rotation angle of the limit plate 67. The limit plate 67 is a polygonal plate, and the adjacent two end faces of the limit plate 67 have an arc transition.

[0056] In this embodiment, the connection portion 68 at one end of the limit rod 66 is connected to the bonding plate 65 through a hinge 69, and the other end of the limit rod 66 is connected to the auxiliary frame 62 through a limit plate 67. The limit rod 66 is arranged perpendicular to the plate surface of the limit plate 67. The limit groove 621 is located on the outer wall of the auxiliary frame 62, and its height in the up and down direction is greater than the height of the limit plate 67. The limit plate 67 is a polygonal plate, which can be a triangle, a rectangle or a pentagon, etc. The swing angle of the limit rod 66 is limited by abutting one side of the limit plate 67 with the bottom wall of the limit groove 621, and then the rotation angle of the exciter 63 is limited by means of the hinge 69, so as to avoid the problem that the bonding plate 65 swings too much and is difficult to contact the bottom wall of the collection bin 1.

[0057] In one possible implementation, see Figures 1 to 11 The lifting drive member 21 is connected to the support frame 2 along the up and down direction. The lifting end of the lifting drive member 21 is provided with a horizontally extending lower support bar 22. The lower support bar 22 is provided with a transverse driving member 23 arranged perpendicular to the central axis direction of the collecting bin 1. The receiving plate 3 is connected above the moving end of the transverse driving member 23.

[0058] In this embodiment, the lifting drive member 21 can drive the receiving tray 3 to move up and down. In order to ensure that the receiving tray 3 is effectively aligned with the lower opening of the collecting bin 1, a transverse driving member 23 is also provided. The transverse driving member 23 can be used to drive the receiving tray 3 to move laterally (that is, perpendicular to the moving direction of the distribution vehicle) to ensure that the receiving tray 3 can be accurately aligned with the lower opening of the collecting bin 1.

[0059] Based on the same inventive concept, an embodiment of the present application also provides a tobacco dispensing trolley assembly, including a dispensing trolley track 9, a dispensing trolley and a self-cleaning tobacco collection system for the dispensing trolley. The dispensing trolley includes a loading and unloading belt conveyor 7 that is rollingly connected to the top of the dispensing trolley track 9 and a limiting frame 8 that is arranged above the loading and unloading belt conveyor 7. Rollers that roll with the dispensing trolley track 9 are respectively provided on both sides of the loading and unloading belt conveyor 7, and a protective cover 85 is provided on the roller cover.

[0060] On this basis, a protective cover 85 is provided on the outside of the roller, and the protective cover 85 includes a protective cover shell and a protective cover door, and the protective cover door is hinged on the outside of the protective cover shell, and the sealing inside the structure can be maintained when the roller is moving. When maintenance is required, the protective cover door can be conveniently opened for maintenance operations.

[0061] The present embodiment provides a tobacco dispensing vehicle assembly, which utilizes a collecting bin 1 to collect tobacco in a centralized manner. When in use, the receiving tray 3 rises, and the collecting bin 1 moves to above the receiving tray 3 and then the sliding door 4 opens. Under the suction action of the suction tube 31, the tobacco in the collecting bin 1 falls into the receiving tray 3 and is sucked away by the suction tube 31, thereby achieving effective collection of tobacco. The above structure can effectively remove tobacco, eliminate the hidden dangers of tobacco insects, and is conducive to improving production efficiency.

[0062] The above are only 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 in the protection scope of the present invention.
