The slider in the first set can restrict the rotation of the first unloading plate relative to the container. The second pulley is drivenly connected to the first end of the first crank in the second set. The slider in the second set can restrict the rotation of the second unloading plate relative to the container. The sliders in the two sets move in opposite directions relative to the container.

[0012] Furthermore, the lower surface of the unloading base plate is provided with an abutment protrusion, and the slider can abut against the abutment protrusion to limit the rotation of the unloading base plate relative to the container; and / or, the container is provided with a guide groove extending along the width direction of the container, and the slider is movably disposed in the guide groove along the extension direction of the guide groove.

[0013] Furthermore, the bottom plate drive component also includes a transmission component, which includes a transmission rod and a connecting rod perpendicular to the drive shaft.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, this embodiment of the invention provides a bottom-opening container, which includes a container 10, a bottom unloading plate 20, a bottom plate locking member 30, and a bottom plate driving member 40. The container 10 has a receiving cavity 11 and a unloading port connected to the receiving cavity 11. The unloading port is located at the lower end of the container 10. The unloading bottom plate 20 is rotatably disposed at the unloading port. The unloading bottom plate 20 has a unloading position with the unloading port open and a transport position with the unloading port closed. The bottom plate locking member 30 has a locked state and an unlocked state. When the bottom plate... When the locking member 30 is in the locked state, the bottom plate locking member 30 can restrict the rotation of the unloading bottom plate 20 relative to the container 10. When the bottom plate locking member 30 is in the unlocked state, the unloading bottom plate 20 can rotate relative to the container 10. The bottom plate driving member 40 is installed on the container 10 and is drivenly connected to the unloading bottom plate 20 and the bottom plate locking member 30 respectively, so that while the bottom plate driving member 40 drives the bottom plate locking member 30 to switch to the unlocked state, the bottom plate driving member 40 drives the unloading bottom plate 20 to rotate from the transport position to the unloading position.

[0033] Using the bottom-opening container provided in this embodiment, the container 10's receiving cavity 11 accommodates the transported goods. When unloading is required, the bottom plate drive 40 drives the bottom plate locking 30 to the unlocked state. Simultaneously, the bottom plate drive 40 drives the unloading bottom plate 20 to rotate from the transport position to the unloading position, opening the unloading port. This allows the goods inside the container 10 to be unloaded through the unloading port at the bottom of the container 10. By simultaneously driving the unloading bottom plate 20 and the bottom plate locking 30 with the bottom plate drive, the opening and closing, locking and unlocking of the unloading bottom plate 20 can be achieved with a single drive. This simplifies the structure of the bottom-opening container and improves the consistency of the opening and closing actions and the locking and unlocking actions of the unloading bottom plate 20, making bottom unloading of the bottom-opening container easier to operate.

[0034] Compared to existing unloading methods that involve unloading from end doors or side doors, bottom-opening containers can improve the unloading efficiency of bulk cargoes such as coal, grain, and ore, reduce unloading costs, and minimize bulk cargo residue.

[0035] Furthermore, compared to the prior art where the unloading base plate 20 is driven to rotate downwards and open by the gravity of the cargo, this embodiment uses the base plate drive component 40 to drive the unloading base plate 20. This can prevent the unloading base plate 20 from opening rapidly due to the gravity of the cargo when the base plate locking component 30 is in the unlocked state. This avoids the cargo from causing excessive impact on the ground or the next process device through the unloading port, reduces unloading impact, and improves unloading safety. The base plate drive component 40 limits the opening speed of the unloading base plate 20, thereby limiting the speed at which the cargo moves downwards through the unloading port and ensuring safety.

[0036] like Figure 2 As shown, the bottom plate drive component 40 includes a drive shaft 41, which extends along the length of the container 10 and is rotatably mounted on the container 10 about its axis. The drive shaft 41 is driven connected to the unloading bottom plate 20 and the bottom plate locking component 30, respectively. By utilizing the drive shaft 41 extending along the length of the container 10, the rotation of the drive shaft 41 about its axis is transmitted to the unloading bottom plate 20 and the bottom plate locking component 30, so that the points of action between the drive shaft 41 and the unloading bottom plate 20 and the points of action between the drive shaft 41 and the bottom plate locking component 30 can be flexibly arranged in the extension direction of the drive shaft 41, and the setting position of the bottom plate locking component 30 can be flexibly selected in the extension direction of the drive shaft 41.

[0037] like Figure 2 As shown, the bottom plate locking member 30 includes a first crank 31, a second crank 32, and a slider 33. The first crank 31 is perpendicular to the drive shaft 41, and the drive shaft 41 is drivenly connected to the first end of the first crank 31. The second crank 32 is perpendicular to the drive shaft 41, and the second end of the first crank 31 is hinged to the first end of the second crank 32. The slider 33 is movably disposed on the container 10 along the width direction of the container 10 and located below the unloading bottom plate 20. The second end of the second crank 32 is hinged to the slider 33 to drive the slider 33 to move. When the bottom plate locking member 30 is in the locked state, the slider 33 abuts against the unloading bottom plate 20. The drive shaft 41 transmits the torque that rotates around its axis to the first end of the first crank 31. The first crank 31, the second crank 32, and the slider 33 constitute a crank-slider mechanism. The torque received by the first end of the first crank 31 is output as the movement of the slider 33 along the width direction of the container 10. The crank-slider mechanism converts the rotation of the drive shaft 41 into the movement of the slider 33, making the structure of the bottom plate locking member 30 simple and the movement reliable.

[0038] like Figure 2As shown, the base plate locking component 30 also includes a speed-increasing mechanism 34. The drive shaft 41 is driven to the input of the speed-increasing mechanism 34, and the output of the speed-increasing mechanism 34 is driven to the first end of the first crank 31. It should be noted that the speed-increasing mechanism 34 refers to a mechanism whose output speed is greater than the speed received by its input speed. By setting the speed-increasing mechanism 34 between the first crank 31 and the drive shaft 41, the speed received by the first end of the first crank 31 is greater than the speed output by the drive shaft 41, thereby enabling the slider 33 to move quickly relative to the unloading base plate 20, preventing the slider 33 from affecting the opening of the unloading base plate 20.

[0039] like Figure 2 As shown, the speed-increasing mechanism 34 includes a driving pulley 341, a driven pulley 342, and a synchronous belt 343. The drive shaft 41 is drivenly connected to the driving pulley 341, and the driven pulley 342 is drivenly connected to the first end of the first crank 31. The diameter of the driving pulley 341 is larger than the diameter of the driven pulley 342. The synchronous belt 343 is fitted onto the driving pulley 341 and the driven pulley 342. Compared with transmission structures such as gear transmission or sprocket transmission, the belt drive composed of the driving pulley 341, the driven pulley 342, and the synchronous belt 343 has the advantages of both the larger diameter of the driving pulley 341 and the larger output speed of the driven pulley 342, which allows the output speed of the driven pulley 342 to be greater than the input speed of the driving pulley 341, and the ease of arranging the driving pulley 341 and the driven pulley 342 relative to the container 10, while also reducing the overall size of the speed-increasing mechanism 34.

[0040] like Figure 2 and Figure 5As shown, the unloading bottom plate 20 includes a first unloading plate 21 and a second unloading plate 22. The side of the first unloading plate 21 facing the second unloading plate 22 and the side of the second unloading plate 22 facing the first unloading plate 21 are both hinged to the middle of the container 10. The first unloading plate 21 and the second unloading plate 22 can open or close the unloading port together. The driven pulley 342 includes a first pulley 3421 and a second pulley 3422. The bottom plate locking member 30 includes two sets of first cranks 31, second cranks 32, and sliders 33. The bottom plate locking member 30 also includes a reversing gear set 35. The wheel set 35 includes a driving gear and a driven gear 352 that mesh with each other. The first pulley 3421 is coaxially arranged with the driving gear and drivenly connected to the driving gear. The driven gear 352 is located at the first end of the first crank 31 in the first set. The slider 33 in the first set can restrict the rotation of the first unloading plate 21 relative to the container 10. The second pulley 3422 is drivenly connected to the first end of the first crank 31 in the second set. The slider 33 in the second set can restrict the rotation of the second unloading plate 22 relative to the container 10. The sliders 33 in the two sets move in opposite directions relative to the container 10. The drive pulley 341 drives the first pulley 3421 and the second pulley 3422 to rotate in the same direction via the synchronous belt 343. By setting the reversing gear set 35, the torque received by the first end of the first crank 31 in the first set is opposite to the torque received by the first end of the first crank 31 in the second set. This makes the sliders 33 in the two sets move in opposite directions relative to the container 10, so that the sliders 33 in the two sets move closer or further away in the width direction of the container 10, simplifying the stroke of the sliders 33 in the two sets to synchronously open or close the unloading bottom plate 20.

[0041] like Figure 5 As shown, an abutment protrusion 23 is provided on the lower surface of the unloading base plate 20. The slider 33 can abut against the abutment protrusion 23 to restrict the rotation of the unloading base plate 20 relative to the container 10. When the slider 33 abuts against the abutment protrusion 23, the slider 33 restricts the unloading base plate 20 from rotating downward relative to the container 10. By utilizing the abutment engagement between the slider 33 and the abutment protrusion 23, the frictional force that the slider 33 needs to overcome to slide can be reduced, the resistance of the base plate locking member 30 switching to the unlocked state can be reduced, and the mating structure of the slider 33 restricting the rotation of the unloading base plate 20 can be easily manufactured.

[0042] like Figure 2 and Figure 5 As shown, the container 10 is provided with a guide groove 13 extending along the width direction of the container 10, and the slider 33 is movably disposed within the guide groove 13 along the extension direction of the guide groove 13. The extension direction of the guide groove 13 guides the movement of the slider 33 relative to the container 10, thereby improving the reliability of the movement of the slider 33.

[0043] Specifically, the guide groove 13 is provided on the lower end beam 15.

[0044] like Figure 4 and Figure 6 As shown, the bottom plate drive component 40 also includes a transmission component 42. The transmission component 42 includes a transmission rod 421 and a connecting rod 422 perpendicular to the drive shaft 41. The drive shaft 41 is drivenly connected to the transmission rod 421. The end of the transmission rod 421 is hinged to the first end of the connecting rod 422. The second end of the connecting rod 422 is hinged to the unloading bottom plate 20. The hinge point between the second end of the connecting rod 422 and the unloading bottom plate 20 and the hinge point between the unloading bottom plate 20 and the container 10 are spaced apart in a direction perpendicular to the length direction of the container 10. With the above structure, the container 10, the transmission rod 421, the connecting rod 422, and the unloading bottom plate 20 form a four-bar linkage structure. The line connecting the second end of the connecting rod 422 and the hinge point of the unloading bottom plate 20 to the drive connection point between the drive shaft 41 and the transmission rod 421 is fixed, transmitting the rotation of the drive shaft 41 around its axis to the transmission rod 421, thereby driving the unloading bottom plate 20 to rotate relative to the container 10.

[0045] like Figure 4 and Figure 6 As shown, the unloading base plate 20 includes a first unloading plate 21 and a second unloading plate 22. The side of the first unloading plate 21 facing the second unloading plate 22 and the side of the second unloading plate 22 facing the first unloading plate 21 are both hinged to the middle of the container 10. The first unloading plate 21 and the second unloading plate 22 can open or close the unloading port together. The connecting rod 422 includes a first rod body 4221 and a second rod body 4222. The drive shaft 41 is drivenly connected to the middle of the transmission rod 421. The two ends of the transmission rod 421 are respectively connected to the first end of the first rod body 4221 and the second rod body 4222. The first end of the first rod 4221 is hinged to the first unloading plate 21, and the second end of the second rod 4222 is hinged to the second unloading plate 22. The hinge point between the second end of the first rod 4221 and the first unloading plate 21, and the hinge point between the first unloading plate 21 and the container 10, are spaced apart in a direction perpendicular to the length direction of the container 10. Similarly, the hinge point between the second end of the second rod 4222 and the second unloading plate 22, and the hinge point between the second unloading plate 22 and the container 10, are also spaced apart in a direction perpendicular to the length direction of the container 10. When the first unloading plate 21 and the second unloading plate 22 close the unloading port, the transmission rod 421, the first rod 4221, and the second rod 4222 are approximately straight, improving the self-locking property of the transmission component 42 and thus ensuring high reliability of the bottom plate drive component 40.

[0046] Specifically, when unloading is required, the drive shaft 41 is rotated, and the drive shaft 41 drives the sliders 33 in the two sets to move closer to each other, so that the sliders 33 separate from the abutting protrusions 23. At the same time, the drive shaft 41 drives the first unloading plate 21 and the second unloading plate 22 to rotate downward through the transmission rod 421, the first rod body 4221 and the second rod body 4222, thereby opening the unloading port.

[0047] In this embodiment, multiple transmission components 42 are arranged at intervals along the length of the container 10, thereby providing a uniform driving force to the unloading base plate 20 along the length of the container 10, making the rotation of the unloading base plate 20 stable and reliable.

[0048] like Figure 7 and Figure 8 As shown, the base plate drive unit 40 also includes an operating lever 43 disposed outside the container 10 and perpendicular to the drive shaft 41. The end of the operating lever 43 is connected to the end of the drive shaft 41, and the operating lever 43 is rotatable relative to the container 10 about the axis of the drive shaft 41. Using the aforementioned operating lever 43 facilitates the application of rotational torque to the drive shaft 41 by workers. Specifically, a rope or other transmission structure can be used, allowing for operation by a single worker on the ground, reducing the number of operators required to open and close the unloading base plate 20.

[0049] like Figure 7 and Figure 8 As shown, container 10 includes a body 14 and a lower end beam 15, with a bottom plate locking member 30 disposed within the lower end beam 15. By placing the bottom plate locking member 30 within the lower end beam 15, the bottom plate locking member 30 is arranged without being exposed, and no additional housing structure is required, simplifying the structure of the bottom-opening container.

[0050] like Figure 1 , Figure 4 , Figure 7 as well as Figure 8 As shown, the container body 14 includes a side panel 141 and a top plate 142 disposed at the upper end of the side panel 141. The lower edge of the side panel 141 is arranged to form a discharge port, making full use of the lower space of the container body 14 to form a discharge port, thereby improving the unloading efficiency of the bottom-opening container and reducing cargo residue.

[0051] like Figure 3 and Figure 6As shown, the unloading bottom plate 20 includes a first unloading plate 21, a second unloading plate 22, and a central beam 24. The central beam 24 is located at the unloading port and extends along the length of the container 10. Both ends of the central beam 24 are connected to the container 10 to divide the unloading port into a first unloading sub-port and a second unloading sub-port. The first unloading plate 21 and the second unloading plate 22 are both hinged to the central beam 24. The first unloading plate 21 is closable at the first unloading sub-port, and the second unloading plate 22 is closable at the second unloading sub-port. Since the first unloading plate 21 and the second unloading plate 22 are both hinged to the central beam 24, it is convenient to set up a bottom plate drive unit 40 to simultaneously drive the opening and closing of the first unloading plate 21 and the second unloading plate 22, simplifying the structure of the bottom-opening container.

[0052] like Figure 3 and Figure 6 As shown, the drive shaft 41 is located inside the central beam 24. The unloading base plate 20 also includes a connecting plate 25 vertically disposed inside the central beam 24. The drive shaft 41 is rotatably mounted on the connecting plate 25 around its axis. The central beam 24 accommodates the drive shaft 41, and the connecting plate 25 provides stable support for the rotating drive shaft 41, preventing the central part of the drive shaft 41 from being suspended in the air.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
