Description

Technical Field

[0001] This invention relates to the field of material transport technology, and in particular to a material transport vehicle. Background Technology

[0002] In the existing technology, palletized boxes, as a type of reusable standardized logistics carrier, have advantages such as flexible assembly and disassembly, convenient stacking, stable structure, and high recycling rate. They have been widely used in warehousing and material transfer, especially in the temporary storage and short-distance transfer of granular materials such as grains, chemical powders, plastic particles, and bulk building materials.

[0003] A standard pallet box mainly consists of a box body and a top cover. The box body is formed by multiple rigid panels enclosing an open storage space at the top; the top cover is installed on the top of the box body and is used to close or open the feed inlet.

[0004] In actual operation, workers need to manually remove the top cover, fill it with materials, and then close it again to seal it, completing the storage or transfer. After arriving at the destination, the cover still needs to be manually opened again to unload the materials. This operation relies entirely on manual repeated opening and closing of the cover, which is complicated, has low unloading efficiency, and cannot achieve rapid gravity discharge of materials, making it difficult to meet the needs of automated production lines for rapid and continuous material supply. Summary of the Invention

[0005] One objective of this application is to provide a material transport vehicle capable of rapid unloading, thereby simplifying the unloading process and improving unloading efficiency, thus meeting the needs of rapid and continuous material supply in automated production lines.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] According to one aspect of this application, a material transport vehicle is provided, comprising: a base structure, a enclosure structure, and a top cover structure; the base structure extends horizontally; a discharge channel is provided on the base structure; a discharge valve for controlling the opening and closing of the discharge channel is provided within the discharge channel; the enclosure structure extends horizontally in a polygonal shape; the enclosure structure is detachably connected to the upper side of the base structure; the enclosure structure is foldable; the top cover structure is detachably connected to the upper side of the enclosure structure; wherein the base structure, the enclosure structure, and the top cover structure enclose a receiving space; the receiving space communicates with the discharge channel.

[0012] In this embodiment, the base support structure has an inspection groove recessed on the periphery of the first limiting groove; the periphery wall of the base support structure has an inspection port relative to the inspection groove, and the inspection port communicates with the inspection groove; the base support structure has an inspection cover plate movably provided on the outside of the inspection port for opening and closing the inspection port.

[0013] In this embodiment, the base support structure includes a base plate and a plurality of first support blocks protruding from the lower side of the base plate. The plurality of first support blocks are arranged in parallel and spaced apart to support the base plate. The top cover structure includes a top plate and a plurality of second support blocks protruding from the upper side of the top plate.

In the horizontal direction, the first support blocks and the second support blocks are staggered. The first receiving groove is used to receive the second support block of another material transport vehicle, and the second receiving groove is used to receive the first support block of another material transport vehicle.

[0014] In this embodiment, the discharge channel passes through the middle of the base plate and the first support block located in the middle; and / or, the inspection groove is located on the periphery of the base plate, and the inspection port is opened on the outermost first support block.

[0015] In this embodiment, the unloading valve is an iris opening and closing structure or a knife gate valve.

[0016] In this embodiment, the base structure is equipped with a weighing device to obtain the weight of the material carried on the base structure.

[0017] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, when the material transport vehicle is in use, granular materials are moved into the containment space to achieve temporary storage and transportation of the materials.

[0029] See Figure 1 For ease of description and understanding, the state of the material transport vehicle during use will be used as a reference, the vertical direction of the material transport vehicle will be the vertical direction in the following text, and the direction perpendicular to the vertical direction will be the horizontal direction in the following text.

[0030] Figure 2 yes Figure 1 Side view of the structure shown. Figure 3 yes Figure 1 The bottom view of the structure shown.

[0031] See Figure 1 , Figure 2 and Figure 3This application provides a material transport vehicle, comprising a base structure 300, a enclosure structure 200, and a top cover structure 100. The base structure 300 extends horizontally. A discharge channel 310 is provided on the base structure 300. A discharge valve 320 for controlling the opening and closing of the discharge channel 310 is provided within it. The enclosure structure 200 extends horizontally in a polygonal shape. The enclosure structure 200 is detachably connected to the upper side of the base structure 300. The enclosure structure 200 is foldable. The top cover structure 100 is detachably connected to the upper side of the enclosure structure 200. The base structure 300, enclosure structure 200, and top cover structure 100 enclose a receiving space, which communicates with the discharge channel 310.

[0032] When the material transport vehicle is in use, the enclosure structure 200 is placed and connected to the base support structure 300, and the top cover structure 100 is placed and connected to the enclosure structure 200, so that the base support structure 300, enclosure structure 200, and top cover structure 100 enclose a accommodating space. The accommodating space is used to accommodate materials, thereby realizing the temporary storage and transportation of materials.

[0033] Once the materials have been transported to their destination, the staff opens the discharge channel 310 through the discharge valve 320, so that the materials in the containment space can be quickly discharged through the discharge channel 310, thereby simplifying the unloading process, improving unloading efficiency, and enabling the material transport vehicle to meet the needs of rapid and continuous material supply in automated production lines.

[0034] After the granular material is discharged from the material transport vehicle, the top cover structure 100, the enclosure structure 200 and the bottom support structure 300 can be disassembled. The enclosure structure 200 can be folded and placed, which facilitates the stacking and transportation of the top cover structure 100, the enclosure structure 200 and the bottom support structure 300, effectively improving the temporary storage and movement of the material transport vehicle when it is idle, and reducing storage and movement costs.

[0035] Figure 4 yes Figure 1 Top view of the structure shown. Figure 5 yes Figure 4 The structural cross-sectional view at point AA. Figure 6 yes Figure 4 Cross-sectional view of the structure at point BB.

[0036] See Figure 4 , Figure 5 and Figure 6 In this embodiment, the base structure 300 may include a base plate 330 and a plurality of first support blocks 340 protruding from the lower side of the base plate 330. The plurality of first support blocks 340 are arranged in parallel and at intervals to support the base plate 330. Furthermore, the plurality of first support blocks 340 are also easy to connect with external structures such as forklifts, thereby facilitating the overall movement of the material transport vehicle and improving the short-distance movement efficiency of the material transport vehicle.

[0037] In some embodiments, the base plate 330 may be separately disposed from the first support block 340. Alternatively, the base plate 330 and the first support block 340 may be integrally formed to effectively improve the structural strength and reliability of the base support structure 300.

[0038] In some embodiments, three first support blocks 340 may be evenly distributed on the underside of the base plate 330. The three first support blocks 340 are arranged in parallel. A first receiving groove 350 is provided between any two adjacent first support blocks 340. The first receiving groove 350 is used to receive the external connecting structure, so that the connecting structure can surround and connect the top cover structure 100 and the bottom support structure 300, pressing the top cover structure 100 onto the enclosure structure 200, and the enclosure structure 200 onto the base plate 330, thereby improving the connection strength and reliability between the top cover structure 100, the enclosure structure 200 and the bottom support structure 300, preventing the material transport vehicle from scattering under external impact, and ensuring the integrity of the material transport vehicle.

[0039] In other embodiments, in the horizontal direction, the two outermost first support blocks 340 are located on the outermost side of the base plate 330 to fully support the base plate 330 and ensure the reliability and stability of the base support structure 300.

[0040] In some embodiments, each of the plurality of first support blocks 340 is provided with two forklift holes 341. The forklift holes 341 extend along the arrangement direction of the plurality of first support blocks 340, so as to allow external forklifts or robotic arms to be inserted into the forklift holes 341 to lift and move the material transport vehicle, thereby improving the stability and safety of the material transport vehicle.

[0041] See Figure 1 , Figure 5 and Figure 6 In this embodiment, a first limiting groove 331 is recessed on the upper side of the base plate 330. The first limiting groove 331 extends horizontally in an annular shape and is provided relative to the enclosure structure 200 to accommodate and engage the lower side of the enclosure structure 200, thereby improving the connection strength and reliability between the base plate 330 and the enclosure structure 200.

[0042] In some embodiments, the first limiting groove 331 may be octagonal to adapt to the enclosure structure 200, thereby accommodating and engaging the enclosure structure 200. In other embodiments, the first limiting groove 331 may be a regular octagon.

[0043] See Figure 1 , Figure 5 and Figure 6In this embodiment, a second limiting groove 332 may also be provided on the base plate 330. The second limiting groove 332 extends horizontally in a rectangular shape. This allows the base support structure 300 to selectively adapt to the octagonal enclosure structure 200 via the first limiting groove 331, and also to selectively adapt to the rectangular enclosure structure 200 via the second limiting groove 332, thereby improving the versatility of the base support structure 300 and reducing its usage cost. In other embodiments, the second limiting groove 332 may be square.

[0044] In some embodiments, the four sides of the second limiting groove 332 coincide with the four sides of the first limiting groove 331 to make full use of the space on the upper side of the base plate 330, increase the effective capacity of the accommodating space, and improve the transportation efficiency of the material transport vehicle.

[0045] See Figure 1 , Figure 5 and Figure 6 In this embodiment, the discharge channel 310 can be provided with a bottom support structure 300 in the vertical direction, thereby facilitating the output of particulate materials in the accommodating space.

[0046] The discharge channel 310 can be sequentially connected to the middle part of the base plate 330 and the first support block 340 located in the middle, so that the material in the accommodating space can pass through the base plate 330 and the first support block 340 and be output to the outside, thereby ensuring the structural strength and reliability of the bottom support structure 300 at the discharge channel 310.

[0047] In some embodiments, the diameter of the discharge channel 310 gradually decreases from top to bottom to facilitate the material's convergence towards the center during discharge. This prevents the particulate material from forming an arched support at the outlet of the discharge channel 310, promoting continuous downward flow of the particulate material. Furthermore, this structure effectively increases the output rate of the particulate material, facilitating its rapid emptying.

[0048] In some embodiments, the discharge valve 320 is located at the lower part of the discharge channel 310 to facilitate operation of the discharge valve 320 by the operator and improve the operating efficiency of the discharge valve 320.

[0049] In other embodiments, the discharge valve 320 can be an iris opening and closing structure to facilitate the rapid opening of the discharge channel 310, so that the particulate material in the discharge channel 310 can be output quickly.

[0050] In related technologies, the iris opening and closing structure can refer to existing iris opening and closing structures to quickly and stably open or close the discharge channel 310. The iris opening and closing structure may include a valve body and multiple valve discs disposed within the valve body. A through valve body channel is provided within the valve body. Multiple valve discs are evenly distributed within the valve body, and each valve disc can approach each other to close the valve body channel, or move away from each other to open the valve body channel, thereby realizing the opening and closing of the discharge channel 310.

[0051] In other embodiments, the discharge valve 320 may be a knife gate valve for quickly opening or closing the discharge channel 310.

[0052] See Figure 5 and Figure 6 In this embodiment, a guide surface 333 is formed on the upper side of the base structure 300. The discharge channel 310 is located within the guide surface 333. The guide surface 333 is inclined towards the discharge port in the top-to-bottom direction. The guide surface 333 guides the particulate material within the accommodating space, allowing the particulate material to move along the guide surface 333 under the action of gravity and pressure, and ultimately converge at the discharge channel 310. This facilitates rapid output of the particulate material, improves the output efficiency of the particulate material, avoids residue of the particulate material, and improves the cleaning efficiency of the material transport vehicle.

[0053] In some embodiments, in the horizontal direction, the guide surface 333 may be located within the enclosure of the first limiting groove 331 to guide the particulate material on the first limiting groove 331 to move toward the discharge channel 310.

[0054] See Figure 1 , Figure 2 and Figure 6 In this embodiment, the base support structure 300 may have an inspection groove 361 recessed on the periphery of the first limiting groove 331. An inspection opening 362 is formed on the periphery of the base support structure 300 relative to the inspection groove 361, and the inspection opening 362 communicates with the inspection groove 361. An inspection cover plate 363 is movably provided on the outside of the inspection opening 362 of the base support structure 300 for opening and closing the inspection opening 362.

[0055] Workers can move the inspection cover 363 to open the inspection port 362, allowing for the removal of some particulate material from the containment space. This facilitates sampling and inspection of the particulate material, improving the convenience and functionality of the material transport vehicle. Workers can also move the inspection cover 363 to close the inspection port 362, ensuring the airtightness of the containment space and preventing leakage of particulate material. Furthermore, it prevents external debris from entering the containment space through the inspection port 362, thus avoiding material contamination.

[0056] In some embodiments, the cross-sectional area of ​​the inspection groove 361 gradually decreases from top to bottom, so that the inner wall of the inspection groove 361 can guide the flow of particulate material. Furthermore, the inner wall of the inspection groove 361 can be inclined toward the inspection port 362, so that the inspection groove 361 can guide the particulate material toward the inspection port 362, thereby facilitating the sampling inspection of particulate material.

[0057] In some embodiments, the inspection slot 361 is located on the periphery of the base plate 330. The inspection slot 361 extends through the floor and a portion of the first support block 340 in a vertical direction. The inspection port 362 may be formed on the outer wall of the first support block 340 to facilitate workers to quickly extract goods through the inspection port 362, thereby improving sampling efficiency.

[0058] In some embodiments, the cover plate 363 is checked to be snap-fitted to the base structure 300 to facilitate the inspection of the removal and installation of the cover plate 363.

[0059] See Figure 5 In this embodiment, the base structure 300 may be equipped with a weighing device 370 to obtain the weight of the material carried on the base structure 300, thereby facilitating the staff to obtain the weight of the granular material in real time.

[0060] In some embodiments, there may be multiple weighing devices 370, which can be respectively disposed between multiple first support blocks 340 and the base plate 330 to obtain the total weight of objects on the base plate 330, thereby enabling the calculation of the total weight of the particulate material. In other embodiments, the base plate 330 may include two plates arranged vertically. A weighing device 370 is disposed between the two plates to obtain the total weight of objects on them, thereby enabling the calculation of the total weight of the particulate material. In other embodiments, the weighing device 370 may also be configured in other ways, such that it can calculate the weight of the particulate material within the accommodating space. In other embodiments, it may not be necessary to install a weighing device 370 within the base structure 300; the total weight of the particulate material can be obtained by weighing the entire material transport vehicle.

[0061] See Figure 1 , Figure 5 and Figure 6 In this embodiment, the enclosure structure 200 extends vertically. The lower end of the enclosure structure 200 is detachably engaged in the first limiting groove 331 or the second limiting groove 332 to achieve a detachable connection between the enclosure structure 200 and the base plate 330. The upper end of the enclosure structure 200 is detachably connected to the top cover structure 100.

[0062] In this embodiment, the enclosure structure 200 can be formed from a single piece of sheet material. The sheet material is first heated and bent, and then the opposing ends of the bent sheet are welded together to form the enclosure structure 200, thereby ensuring the overall structural strength and reliability of the enclosure structure 200. Furthermore, the enclosure panels can be folded at the bends and welds, allowing the enclosure structure 200 to be folded for storage, facilitating its storage and transportation, reducing the storage volume of material transport vehicles, and lowering storage and transportation costs.

[0063] In some embodiments, the enclosure structure 200 may also be formed by hinged multiple enclosure panels. On the one hand, the multiple enclosure panels can rotate to enclose and form a polygonal enclosure structure 200, thereby facilitating connection with the base support structure 300 and the top cover structure 100. On the other hand, the multiple enclosure panels can rotate and fold for storage, thereby facilitating the placement and transportation of material transport vehicles.

[0064] In some embodiments, the enclosure structure 200 may be octagonal in the horizontal direction to fit and engage with the first limiting groove 331, thereby facilitating the engagement connection between the enclosure structure 200 and the base plate 330. In other embodiments, the enclosure structure 200 may be a regular octagon.

[0065] In some embodiments, the enclosure structure 200 may also be rectangular in the horizontal direction to fit and engage with the second limiting groove 332, thereby facilitating the engagement connection between the enclosure structure 200 and the base plate 330. In other embodiments, the enclosure structure 200 may be square.

[0066] Compared to a rectangular enclosure structure 200, when the enclosure structure 200 is octagonal, the side walls of the enclosure structure 200 can improve their structural strength, thereby increasing the enclosure structure 200's resistance to lateral compressive forces and tensile strength. This helps prevent problems such as box bulging and side wall warping deformation of granular materials during storage and transportation, avoids leakage of granular materials, and ensures the safety of material transport vehicles.

[0067] In some embodiments, the enclosure structure 200 may also be other polygonal shapes to enclose and form an accommodating space with the top cover structure 100 and the bottom support structure 300, and can be folded for placement to reduce the space volume required for transportation. In other embodiments, the enclosure structure 200 may also be hexagonal, dodecagonal, etc.

[0068] In some embodiments, the enclosure structure 200 may also be recessed with a hand grip groove to facilitate workers to move and operate the enclosure structure 200 through the hand grip groove.

[0069] See Figure 1 , Figure 5 and Figure 6In this embodiment, the top cover structure 100 includes a top plate 110 and a plurality of second support blocks 120 protruding from the upper side of the top plate 110. The top plate 110 is used to connect with the enclosure structure 200 so that the top plate 110, the enclosure structure 200 and the bottom plate 330 enclose and form an accommodating space. The plurality of second support blocks 120 are arranged in parallel and at intervals to improve the structural strength and reliability of the top plate 110.

[0070] In some embodiments, the top plate 110 and the second support block 120 can be separately disposed. In other embodiments, the top plate 110 and the second support block 120 can be integrally formed.

[0071] See Figure 5 and Figure 6 In this embodiment, the lower side of the top cover structure 100 may be recessed with a third limiting groove 111. In the horizontal direction, the third limiting groove 111 extends horizontally in an octagonal shape corresponding to the first limiting groove 331, so as to accommodate the top of the octagonal enclosure structure 200, thereby realizing the engaging connection between the top plate 110 and the enclosure structure 200, and improving the structural strength and reliability of the material transport vehicle.

[0072] In some embodiments, the lower side of the top cover structure 100 may also be recessed with a fourth limiting groove 112. In the horizontal direction, the fourth limiting groove 112 extends horizontally in a rectangle corresponding to the second limiting groove 332, so as to accommodate the top of the rectangular enclosure structure 200, thereby realizing the engaging connection between the top plate 110 and the enclosure structure 200, so that the top cover structure 100 and the bottom support structure 300 can be adapted to enclosure structures 200 of various shapes, improving the versatility of the top cover structure 100 and the bottom support structure 300, and making it suitable for accommodating various particulate materials.

[0073] In some embodiments, the four sides of the fourth limiting groove 112 coincide with the four sides of the third limiting groove 111 to make full use of the space under the top plate 110, increase the effective capacity of the accommodating space, and improve the transportation efficiency of the material transport vehicle.

[0074] See Figure 1 , Figure 5 and Figure 6In this embodiment, the arrangement direction of the second support block 120 is the same as that of the first support block 340. A first receiving groove 350 is provided between any two adjacent first support blocks 340. A second receiving groove 130 is provided between any two adjacent second support blocks 120. In the horizontal direction, the first support blocks 340 and the second support blocks 120 are staggered. The first receiving groove 350 is used to accommodate the second support block 120 of another material transport vehicle, and the second receiving groove 130 is used to accommodate the first support block 340 of another material transport vehicle, thereby facilitating the stacking of multiple material transport vehicles. On the one hand, this improves the reliability and stability of stacking multiple material transport vehicles; on the other hand, it reduces the overall volume of multiple material transport vehicles, thereby increasing the transport capacity of the material transport vehicles.

[0075] In some embodiments, three first support blocks 340 protrude from the lower side of the base plate 330. Two second support blocks 120 protrude from the upper side of the top plate 110. The first support blocks 340 and the second support blocks 120 are staggered. Two first receiving grooves 350 between the three first support blocks 340 can accommodate two second support blocks 120 on the top of another material transport structure, thereby facilitating the stacking of multiple material transport vehicles.

[0076] See Figure 1 , Figure 5 and Figure 6 In this embodiment, the material transport vehicle may further include a connecting belt. The connecting belt surrounds the top cover structure 100 and the bottom support structure 300 to press the top cover structure 100 onto the enclosure structure 200, and the enclosure structure 200 onto the bottom support structure 300, thereby ensuring the overall structural strength, reliability, and stability of the material transport vehicle. Furthermore, the plastic bag facilitates intermittent disassembly, improving the disassembly efficiency of the material transport vehicle and facilitating its folding and transport.

[0077] In some embodiments, the connecting strap can pass through the forklift hole 341 and surround the top cover structure 100 and the bottom support structure 300 to further improve the reliability of the material transport vehicle and prevent the connecting strap from shifting or deforming due to external force.

[0078] In some embodiments, the second support block 120 may have a first connecting groove 121 recessed relative to the forklift hole 341. The first connecting groove 121 is used to accommodate the connecting belt so that the connecting belt can pass through the forklift hole 341 and the first connecting groove 121, thereby preventing the connecting belt from sliding or falling off on the top cover structure 100 and improving the structural strength and reliability of the material transport vehicle.

[0079] In some embodiments, the connecting belt can pass through the first receiving groove 350 and surround the top cover structure 100 and the bottom support structure 300 to further improve the reliability of the material transport vehicle and prevent the connecting belt from shifting or deforming due to external force.

[0080] In other embodiments, the second support block 120 may have a second connecting groove 122 recessed relative to the first receiving groove 350. The second connecting groove 122 is used to receive the connecting belt so that the connecting belt can pass through the first receiving groove 350 and the second connecting groove 122, thereby preventing the connecting belt from sliding or falling off on the top cover structure 100 and improving the structural strength and reliability of the material transport vehicle.

[0081] In related technologies, particulate materials can be wrapped in packaging bags and then placed together in the containment space of a material transport vehicle.

[0082] The material transport vehicle is adaptable to automated scenarios. In such scenarios, an automated robotic arm can lift the material transport vehicle through the forklift port 341 and open the unloading valve 320. Subsequently, the packaging bag is pierced through the discharge channel 310 by the piercing structure, allowing the granular material inside the packaging bag to enter the discharge channel 310 along the guide surface 333 under the action of gravity and pressure, and finally be output to the outside. This reduces the number of steps required to use the material transport vehicle and effectively improves the output and utilization efficiency of granular materials.

[0083] See Figures 1 to 6 This application provides a material transport vehicle. When the material transport vehicle transports granular materials, the enclosure structure 200 is first connected to the base support structure 300, and then the granular materials are placed into the accommodating space. Afterwards, the top cover structure 100 is placed on the enclosure structure 200, and the top cover structure 100, enclosure structure 200, and base support structure 300 are connected by a connecting strap, thereby ensuring the stability and reliability of the material transport vehicle.

[0084] Multiple material transport vehicles are stacked and then transported. After the material transport vehicles arrive at their destination, the robotic arm lifts the material transport vehicles through the forklift hole 341, and then opens the unloading valve 320 so that the material in the accommodating space can be quickly output through the discharge channel 310. This simplifies the use of the material transport vehicles, improves unloading efficiency, facilitates the rapid removal and use of granular materials, and meets the needs of rapid and continuous material supply in automated production lines.

[0085] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined. For example, the top cover structure 100 can only have a top plate 110, without the need for a second support block 120.

[0086] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
