[0001] The utility model relates to the technical field of transportation equipment, in particular to a rail transport vehicle. Background Art

[0002] Tobacco leaf harvesting is a very important part of tobacco planting, which is directly related to the quality and yield of tobacco leaves. Correct harvesting technology can ensure the quality indicators of tobacco leaves such as color, aroma and taste. In the process of tobacco leaf harvesting, the harvesting time of tobacco leaves is very critical, which directly affects the quality of tobacco leaves. Generally speaking, the harvesting time should be carried out when the tobacco leaves reach the best maturity. Harvesting too early or too late will affect the quality of tobacco leaves.

[0003] Since the picking window is short (each time tobacco leaves are picked, they should be completed within 1-2 days), and it is best to pick them in the morning and after 5:00 pm, avoiding periods of strong sunlight, each picking operation has the problem of short time and heavy tasks. However, when picking tobacco leaves, workers are currently required to pack the picked tobacco leaves and then carry the tobacco packs to the field manually. The workers have high labor intensity and low work efficiency, and are prone to miss the best harvesting time. Utility Model Content

All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0042] For the convenience of description, the moving direction of the transport vehicle 2 is now defined as the front-to-back direction, the horizontal direction perpendicular to the front-to-back direction is defined as the left-to-right direction, and the front-to-back direction is defined as the longitudinal direction, and the left-to-right direction is defined as the transverse direction.

[0043] Embodiment 1

[0044] like Figure 1 As shown, a rail transport vehicle comprises a rail and a transport vehicle 2 capable of moving along the rail.

[0045] In order to adapt to different conveying distances, the track is composed of a plurality of track monomers 1 connected end to end. The track monomer 1 includes two parallel guide rails 11, and a plurality of bottom plates 12 are evenly arranged between the two guide rails 11 and below the guide rails 11 along the length direction of the guide rails 11. The two ends of the bottom plates 12 are fixedly connected to the lower side of the guide rails 11 by welding.

[0046] As a specific implementation, the guide rail 11 described in this embodiment is made of angle steel, and the back of the guide rail 11 faces upward, and the end of the first wing plate 2512 of the guide rail 11 is fixedly connected to the bottom plate 12 by welding.

[0047] like Figure 2 and Figure 4 As shown, the transport vehicle 2 comprises a base frame 21, on the lower side of which a driving component 22, a power component and a driven component 24 are sequentially arranged along the longitudinal direction.

[0048] like Figure 2 and Fig. 9 As shown, the driving component 22 includes driving wheels 221 respectively located on the left and right sides of the chassis 21 and a driving motor 222 for driving the driving wheels 221 to rotate, and the driving wheels 221 cooperate with the guide rail 11 to move along the guide rail 11. As a specific implementation, the driving component 22 described in this embodiment also includes a differential 223, and the two driving wheels 221 are respectively arranged on the output ends at both ends of the differential 223, and the power output shaft of the driving motor 222 is connected to the input end of the differential 223. The mounting seats 2231 at both ends of the differential 223 are respectively fixedly connected to the chassis 21 in a detachable manner. Exemplarily, the mounting seats 2231 at both ends of the differential 223 are respectively fixedly connected to the chassis 21 by bolt assemblies.

[0049] like Figure 2 and Figure 4As shown, the power component includes a battery box 23, in which a controller (not shown) and a battery (not shown) for providing power to the driving component 22 are arranged. The battery box 23 is fixedly connected to the base frame 21 in a detachable manner.

[0050] like Figure 2 As shown, the driven component 24 includes driven wheels 241 respectively arranged on the left and right sides of the base frame 21 , and the driven wheels 241 cooperate with the guide rail 11 and can move along the guide rail 11 .

[0051] As a specific implementation method, Figure 5 , Figure 6 and Fig. 9 As shown, in this embodiment, the left and right sides of the lower side of the base frame 21 are respectively provided with a first mounting frame, and the first mounting frame includes a vertical rod 211 respectively located on the inner and outer sides of the driven wheel 241 (with the side opposite to the two driven wheels 241 as the inner side), and the driven wheel 241 is connected to the first mounting frame through a connecting shaft 242.

[0052] Furthermore, for the convenience of installation, the connecting shaft 242 sequentially passes through the two first mounting frames in the transverse direction, and the vertical rod 211 of the first mounting frame is provided with a mounting hole 2111 that matches the connecting shaft 242. The cross section of the connecting shaft 242 is a non-circular structure, and the mounting hole 2111 matches the connecting shaft 242 to limit the degree of freedom of the connecting shaft 242 to rotate around its own axis. As a specific implementation, Fig.10 and Fig.11 As shown, the connecting shaft 242 described in this embodiment is provided with a flat opening 2421 , and the shape of the mounting hole 2111 is consistent with the cross section of the connecting shaft 242 .

[0053] A positioning sleeve 243 is sleeved on the connecting shaft 242 between the two first mounting frames. The positioning sleeve 243 is fixedly connected to the connecting shaft 242 in a detachable manner, and the two ends of the positioning sleeve 243 respectively abut against the vertical rod 211 located on the inner side (the side opposite to the two driven wheels 241 is the inner side) of the first mounting frame. The positioning sleeve 243 limits the freedom of the connecting shaft 242 to move in the axial direction. As a specific implementation, the sleeve in this embodiment is provided with a locking bolt 244 that penetrates the sleeve in the radial direction, and the locking bolt 244 is provided with a locking nut 245. The connecting shaft 242 is provided with a fixing hole 2422 for accommodating the locking bolt 244.

[0054] Under the joint action of the mounting hole 2111 and the positioning sleeve 243, the mounting and fixing of the connecting shaft 242 is achieved, so that the connecting shaft 242 can be reliably fixed on the two first mounting frames.

[0055] The driven wheel 241 includes a coaxially arranged driven wheel body 2411 and a transition sleeve 2412. The driven wheel body 2411 is rotatably connected to the transition sleeve 2412 via a bearing assembly 2413. The transition sleeve 2412 is provided with a mounting through hole that matches the connecting shaft 242.

[0056] The reason for this design is that the driven wheel 241 is designed as a single component. When disassembling, it is only necessary to remove the locking bolt 244 and then pull out the connecting shaft 242 to remove the driven wheel 241. The installation process is similar and will not be repeated here. In this way, once the driven wheel 241 is damaged, it can be easily replaced.

[0057] Furthermore, in order to facilitate the installation and removal of the power unit, it is convenient for future repair and maintenance. Figure 4 As shown, the front and rear ends of the battery box 23 are slidably connected to the base frame 21 through sliding components, and a locking mechanism 25 for locking and positioning the battery box 23 is provided between the battery box 23 and the base frame 21.

[0059] As a specific implementation, the battery box 23 described in this embodiment includes a box body 231, and a frame 232 formed by welding of profiles is arranged inside the box body 231, and the box body 231 is fixedly connected to the frame 232 by welding. Exemplarily, the frame 232 includes a square frame formed by four side beams connected end to end in sequence, and the four corners of the square frame are respectively provided with vertical beams extending upward, and the upper ends of the vertical beams are fixedly provided with connecting plates by welding. The two ends of the guide slide 233 located on the front side are fixedly connected to the two connecting plates located on the front side by screws, and the two ends of the guide slide 233 located on the rear side are fixedly connected to the two connecting plates located on the rear side by screws.

[0060] like Figure 3 and Figure 8As shown, the locking mechanism 25 includes a fixing frame 251 fixedly arranged on the lower side of the base frame 21. The fixing frame 251 includes a first web 2511, and the first web 2511 is fixedly connected to the base frame 21 by screws. The left and right ends of the first web 2511 are respectively provided with first wing plates 2512 extending downward perpendicularly to the first web 2511, and the first web 2511 and the first wing plates 2512 together form a U-shaped structure with an opening facing downward. A rotating frame 252 is rotatably arranged between the two first wing plates 2512. The rotating frame 252 includes a second web 2521, and the two ends of the second web 2521 are respectively provided with second wing plates 2522 extending to one side perpendicularly to the second web 2521, and the second web 2521 and the second wing plates 2522 together form a U-shaped structure. A hinge shaft 2523 is provided on the outer side of the second wing plate 2522 (the side opposite to the two second wing plates 2522 is the inner side), and a hinge hole matching with the hinge shaft 2523 is provided on the first wing plate 2512 .

[0061] A positioning pin 253 is provided on the second web 2521 of the rotating frame 252, and a guide hole matching the positioning pin 253 is provided on the second web 2521. Under the guidance of the guide hole, the positioning pin 253 can slide back and forth relative to the second web 2521. A limiting member and a baffle 2531 are provided on both sides of the rotating frame 252 of the positioning pin 253, and a spring 254 is sleeved on the positioning pin 253 between the baffle 2531 and the rotating frame 252. A positioning hole 234 matching the positioning pin 253 is provided on the battery box 23.

[0062] As a specific implementation, the position-limiting member described in this embodiment is a hand wheel 2532. Here, the hand wheel 2532 not only plays a position-limiting role, but also facilitates operation as a gripping member.

[0063] As a specific implementation method, Figure 7 As shown, four locking mechanisms 25 are provided between the battery box 23 and the base frame 21 in this embodiment. Two locking mechanisms 25 are provided on the front and rear sides of the battery box 23, respectively, and the two locking mechanisms 25 on the same side are located at the left and right ends of the battery box 23, respectively.

[0064] like Fig.16 and Fig.17As shown, when the locking mechanism 25 needs to be opened, the positioning pin 253 is first pulled outward so that the end of the positioning pin 253 is separated from the battery box 23, and then the rotating frame 252 is rotated downward until the positioning pin 253 is in a vertical state, and then the hand wheel 2532 is released. At this time, the positioning pin 253 will move upward under the action of the spring 254 until the end of the positioning pin 253 rests on the first belly plate 2511 of the fixing frame 251.

[0065] Furthermore, in order to prevent the cigarette packs from falling off the transport vehicle 2 during transportation, Figure 1 As shown, a guardrail is provided at the edge of the base frame 21. As a specific embodiment, the guardrail described in this embodiment includes guard frames 261 respectively located at the front and rear ends of the base frame 21, and the guard frame 261 includes a web bar and wing bars located at both ends of the web bar, and the web bar and the wing bar together form a U-shaped structure with an opening facing downward, and the lower end of the wing bar is fixedly connected to the base frame 21 by welding. Connecting rods 262 are respectively provided on both sides of the two guard frames 261, and the two ends of the connecting rod 262 are respectively fixedly connected to the wing bars of the guard frames 261 by welding.

[0066] Furthermore, in order to avoid misalignment and deformation between the rail monomers 1 during transportation, Fig.14 and Fig.15 As shown, a first positioning plate 111 is provided inside the guide rail 11 at one end of the guide rail 11, and the first positioning plate 111 extends along the length direction of the guide rail 11, and one end of the first positioning plate 111 extends to the outside of the guide rail 11. A second positioning plate 112 is provided inside the guide rail 11 at the other end of the guide rail 11. The first positioning plate 111 is provided with a slot 1111 that matches the second positioning plate 112.

[0067] Furthermore, the outer side surface of the second positioning plate 112 is flush with the end surface of the guide rail 11, and the side surface of the slot 1111 close to the guide rail 11 is flush with the end surface of the guide rail 11. In this way, when the second positioning plate 112 is inserted into the slot 1111, the end surfaces of the two guide rails 11 can be matched, thereby ensuring the stability and continuity of the operation of the transport vehicle 2.

[0068] Furthermore, if Fig.14 and Fig.15As shown, the side of the slot 1111 facing away from the guide rail 11 is an inclined surface, and the slot 1111 is generally a V-shaped structure with the opening facing upward. In this way, during installation, it is only necessary to insert the second positioning plate 112 into the opening of the slot 1111, and the second positioning plate 112 will move downward under the guidance of the inclined surface until it slides to the bottom end of the slot 1111, thereby realizing the splicing and installation of the track unit 1.
