[0002] With the rapid development of the construction industry, the demand for steel bars is constantly increasing. The efficiency and continuity of steel bar processing production lines have become key factors affecting the overall production progress. In traditional steel bar production equipment, after processes such as cutting and bending, the steel bars are stored in a finished product silo. However, when the finished product silo is full, workers need to manually clean the steel bars in the silo before continuing subsequent processing operations. This process is not only time-consuming and labor-intensive, but also forces the entire production line to stop and wait, seriously affecting processing efficiency and production continuity. Utility Model Content
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a hopper replacement device that can improve the production efficiency of steel bars.
[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0005] In a first aspect, this application provides a hopper changing device having a first direction, a second direction, and a third direction, wherein the first direction, the second direction, and the third direction are mutually perpendicular. The hopper changing device includes: a unloading assembly, including an unloading frame, a first conveyor, and a second conveyor, wherein the first conveyor and the second conveyor are both connected to the unloading frame and both rotate relative to the unloading frame around the second direction, and the first conveyor and the second conveyor are spaced apart along the third direction; and a transfer assembly, including a transfer component, a lifting component, and a third conveyor, wherein the transfer component is spaced apart from the unloading frame along the first direction and moves relative to the unloading frame along the first direction, the lifting component is connected to the transfer component and moves relative to the transfer component along the third direction, and the third conveyor is connected to the lifting component and rotates relative to the lifting component around the second direction.
[0006] In an optional embodiment, the lifting member has a lifting part and a connecting part connected to the lifting part. The lifting part is connected to the transfer member and moves relative to the transfer member along the third direction. The connecting part is connected to the third conveying member, and the third conveying member rotates relative to the connecting part about the second direction.
[0007] In an optional embodiment, the connecting portion is provided with a clearance groove, the clearance groove extends along the first direction, a plurality of the third conveying components are disposed in the clearance groove, the plurality of the third conveying components are spaced apart along the first direction, and each of the third conveying components rotates around the second direction within the clearance groove.
[0008] In an optional embodiment, the lifting components are connected to both ends of the transfer component along the second direction, and each of the lifting components is connected to the third conveyor component.
[0009] In an optional embodiment, a plurality of first conveying members are provided at both ends of the unloading rack along the second direction, and at the same end of the unloading rack along the second direction, the plurality of first conveying members are spaced apart along the first direction.
[0010] In an optional embodiment, a plurality of second conveying members are provided at both ends of the unloading rack along the second direction, and at the same end of the unloading rack along the second direction, the plurality of second conveying members are spaced apart along the first direction.
[0011] In an optional embodiment, the hopper changing device further includes a transfer frame, which is spaced apart from the unloading frame along a first direction to define a moving space. The transfer frame has a clearance space that communicates with the moving space, and the transfer component moves along the first direction within the clearance space and the moving space.
[0012] In an optional embodiment, the transfer assembly further includes a guide member extending along the first direction within the clearance space and the movement space, the transfer member being connected to the guide member, and the transfer member moving relative to the guide member along the first direction.
[0013] In an optional embodiment, the hopper changing device further includes a discharge component disposed on the side of the discharge frame away from the transfer frame along the first direction.

[0014] Secondly, this application provides a steel bar production equipment, including: a silo replacement device as described in any of the foregoing embodiments.
[0015] The hopper changing device of this application has the following advantages:
[0016] In the hopper replacement device of this application, a full hopper can be placed on the third conveyor of the transfer assembly. The full hopper is then transferred to the unloading rack location by the movement of the transfer assembly along the first direction. Since the lifting component moves relative to the transfer assembly along the third direction, when the transfer assembly transfers the full hopper to the unloading rack along the first direction, the lifting component can move the full hopper to the location of the first or second conveyor along the third direction, and the third conveyor rotates around the second direction to transfer the full hopper to the first or second conveyor along the first direction. This facilitates the unloading of the steel bars in the full hopper on the unloading rack. Simultaneously, during the unloading process, another full hopper can be transferred to the first or second conveyor where no hopper is placed, so that both an unloading hopper (or an empty hopper) and a full hopper can exist on the unloading rack at the same time. This allows for buffering of the hoppers on the unloading rack, thereby reducing the impact of the unloading process on other processes in the steel bar production process and improving the steel bar production efficiency.

[0036] Reference Figure 1 , Figure 3 as well as Figure 4 As shown, the hopper changing device 10 involved in the embodiments of this application has a first direction x, a second direction y and a third direction z, the first direction x, the second direction y and the third direction z are perpendicular to each other, and the hopper changing device 10 includes: unloading component 100 and transfer component 200.
[0037] Specifically, the unloading assembly 100 includes an unloading rack 110, a first conveyor 120, and a second conveyor 130. Both the first conveyor 120 and the second conveyor 130 are connected to the unloading rack 110 and rotate relative to the unloading rack 110 about a second direction y. The first conveyor 120 and the second conveyor 130 are spaced apart along a third direction z. The transfer assembly 200 includes a transfer component 210, a lifting component 220, and a third conveyor 230. The transfer component 210 is spaced apart from the unloading rack 110 along a first direction x and moves relative to the unloading rack 110 along the first direction x. The lifting component 220 is connected to the transfer component 210 and moves relative to the transfer component 210 along a third direction z. The third conveyor 230 is connected to the lifting component 220 and rotates relative to the lifting component 220 about a second direction y.
[0038] It should be noted that the first direction x is Figure 1 The direction indicated by x in the middle, and the second direction y is... Figure 1 The direction indicated by y in the middle, and the direction of the third direction z are... Figure 1 The direction indicated by z in the middle.
[0039] In the hopper changing device 10 of this application, a full hopper 20 can be placed on the third conveyor 230 of the transfer assembly 200, so that the full hopper 20 can be transferred to the location of the unloading rack 110 by the movement of the transfer member 210 along the first direction x. Since the lifting member 220 moves relative to the transfer member 210 along the third direction z, when the transfer member 210 transfers the full hopper 20 to the unloading rack 110 along the first direction x, the lifting member 220 can move the full hopper 20 to the location of the first conveyor 120 or the second conveyor 130 along the third direction z, and the third conveyor 230 can rotate around the second direction y to transfer the full hopper 20 to the location of the first conveyor 120 or the second conveyor 130. The steel bars are conveyed along the first direction x to the first conveyor 120 or the second conveyor 130 so that the steel bars in the full hopper 20 can be unloaded on the unloading rack 110. At the same time, during the unloading process, another full hopper 20 can be transferred to the one without a hopper 20 in the first conveyor 120 and the second conveyor 130 by the transfer member 210. This allows the unloading rack 110 to simultaneously have both unloading hoppers 20 (or empty hoppers 20) and full hoppers 20, so that the hoppers 20 can be buffered on the unloading rack 110. In this way, the impact of the unloading process on other processes in the steel bar production process can be reduced, thereby improving the production efficiency of steel bars.
[0040] Reference Figure 4 As shown, the lifting member 220 has a lifting part 221 and a connecting part 222 connected to the lifting part 221. The lifting part 221 is connected to the transfer member 210 and moves relative to the transfer member 210 along a third direction z. The connecting part 222 is connected to the third transmission member 230, and the third transmission member 230 rotates relative to the connecting part 222 about a second direction y.
[0041] In this embodiment, since the connecting part 222 is connected to the lifting part 221, and the lifting part 221 is connected to the transfer member 210, and the lifting part 221 moves relative to the transfer member 210 along a third direction z, the connecting part 222 can be moved relative to the transfer member 210 along a third direction z by the lifting part 221. Since the connecting part 222 is connected to the third conveyor 230, when the connecting part 222 moves relative to the transfer member 210 along a third direction z, the third conveyor 230 can be moved along a third direction z by the connecting part 222, so as to move the full hopper 20 on the third conveyor 230 along a third direction z to the location where the first conveyor 120 and the second conveyor 130 are without a hopper 20. Since the third conveyor 230 rotates relative to the connecting part 222 about a second direction y, the full hopper 20 can be transferred along a first direction x to the location where the first conveyor 120 and the second conveyor 130 are without a hopper 20 by the third rotating member.
[0042] Continue to refer to Figure 4As shown, the connecting part 222 is provided with a clearance groove 2221, which extends along the first direction x. A plurality of third conveying members 230 are provided in the clearance groove 2221. The plurality of third conveying members 230 are spaced apart along the first direction x, and each third conveying member 230 rotates around the second direction y in the clearance groove 2221.
[0043] In this embodiment, since multiple third conveying members 230 are spaced apart along the first direction x, the hopper 20 can be placed on the multiple third conveying members 230 to improve the stability of the hopper 20 placement. At the same time, the efficiency of the hopper 20 moving relative to the transfer assembly 200 along the first direction x is improved to ensure that the hopper 20 can move along the first direction x. Since the multiple third conveying members 230 are disposed in the clearance groove 2221, the clearance groove 2221 can provide clearance space 310 for the rotation of the multiple third conveying members 230 around the second direction y, so as to avoid interference between the third conveying members 230 and the connecting part 222 during the rotation.
[0044] Continue to refer to Figure 4 As shown, the transfer component 210 is connected to lifting components 220 at both ends along the second direction y, and each lifting component 220 is connected to the third transfer component 230.
[0045] In this embodiment, since both ends of the transfer member 210 along the second direction y are connected to lifting members 220, and each lifting member 220 is connected to the third conveyor 230, in the second direction y, the lifting members 220 at both ends of the transfer member 210 can make the third conveyor 230 at both ends of the transfer member 210 move along the third direction z, so that the hopper 20 placed on the third conveyor 230 can move along the third direction z at both ends of the second direction y, thereby ensuring the consistency of movement of the hopper 20 and ensuring that the hopper 20 can be smoothly transferred to the unloading rack 110.
[0046] Reference Figure 2 as well as Figure 3 As shown, the unloading rack 110 is provided with multiple first conveying components 120 at both ends along the second direction y. On the same end of the unloading rack 110 along the second direction y, the multiple first conveying components 120 are arranged at intervals along the first direction x.
[0047] In this embodiment, since multiple first conveying members 120 are provided at both ends of the unloading rack 110 along the second direction y, when the hopper 20 is transferred to the first conveying member 120, a first bearing platform can be formed by the multiple first conveying members 120 at both ends of the unloading rack 110 along the second direction y, so as to support the hopper 20 and improve the stability of the hopper 20 placed on the unloading rack 110. Furthermore, since multiple first conveying members 120 are spaced apart along the first direction x at the same end of the unloading rack 110 along the second direction y, when the hopper 20 is transferred between the unloading rack 110 and the transfer assembly 200, the efficiency of the hopper 20 moving relative to the unloading rack 110 along the first direction x can be improved, so as to ensure that the hopper 20 can move along the first direction x.
[0048] Continue to refer to Figure 2 as well as Figure 3 As shown, the unloading rack 110 is provided with multiple second conveying components 130 at both ends along the second direction y. On the same end of the unloading rack 110 along the second direction y, the multiple second conveying components 130 are spaced apart along the first direction x.
[0049] In this embodiment, since multiple second conveying members 130 are provided at both ends of the unloading rack 110 along the second direction y, when the hopper 20 is transferred to the second conveying member 130, a first bearing platform can be formed by the multiple second conveying members 130 at both ends of the unloading rack 110 along the second direction y, so as to support the hopper 20 and improve the stability of the hopper 20 placed on the unloading rack 110. Furthermore, since multiple second conveying members 130 are spaced apart along the first direction x at the same end of the unloading rack 110 along the second direction y, when the hopper 20 is transferred between the unloading rack 110 and the transfer assembly 200, the efficiency of the hopper 20 moving relative to the unloading rack 110 along the first direction x can be improved, so as to ensure that the hopper 20 can move along the first direction x.
[0050] Continue to refer to Figure 2 as well as Figure 3 As shown, the hopper changing device 10 also includes a transfer frame 300. The transfer frame 300 and the unloading frame 110 are spaced apart along the first direction x to define a moving space 400. The transfer frame 300 is provided with a clearance space 310, which is connected to the moving space 400. The transfer component 210 moves along the first direction x within the clearance space 310 and the moving space 400.
[0051] In this embodiment, the full hopper 20 can be placed on the transfer frame 300, so that the transfer component 200 can transfer the full hopper 20 on the transfer frame 300 to the unloading frame 110. This allows the full hopper 20 to be temporarily buffered on the transfer frame 300, reducing the impact on the steel bar production process. During this process, since the clearance space 310 is connected to the moving space 400, and the transfer component 210 moves along the first direction x within the clearance space 310 and the moving space 400, the transfer component 210 can be directed towards the transfer frame 300 along the first direction x. The transfer component 210 moves from the moving space 400 to the clearance space 310, so that the transfer component 210 moves to the transfer frame 300. Then, the lifting component 220 moves along the third direction z to move the third transfer component 230 along the third direction z to contact the hopper 20 on the transfer frame 300, and lifts the hopper 20 on the transfer frame 300 along the third direction z, so as to facilitate the separation of the hopper 20 on the transfer frame 300 from the transfer frame 300, and facilitate the transfer of the hopper 20 from the transfer frame 300 to the transfer assembly 200.
[0052] Continue to refer to Figure 2 as well as Figure 3 As shown, the transfer assembly 200 also includes a guide 240, which extends along the first direction x and is disposed within the clearance space 310 and the movement space 400. The transfer component 210 is connected to the guide 240, and the transfer component 210 moves relative to the guide 240 along the first direction x.
[0053] In this embodiment, since the guide member 240 extends along the first direction x and is disposed within the clearance space 310 and the movement space 400, the transfer member 210 is connected to the guide member 240, and the transfer member 210 moves relative to the guide member 240 along the first direction x, the guide member 240 can guide the movement of the transfer member 210 to ensure that the transfer member 210 can always move along the first direction x within the clearance space 310 and the movement space 400.
[0054] Continue to refer to Figure 2 as well as Figure 3 As shown, the hopper changing device 10 also includes a discharge component 500. The discharge component 500 is disposed on the side of the discharge rack 110 away from the transfer rack 300 along the first direction x. The discharge component 500 moves relative to the discharge rack 110 along the third direction z and rotates around the third direction z.
[0055] In this embodiment, since the unloading component 500 moves relative to the unloading frame 110 along the third direction z and rotates around the third direction z, the unloading component 500 can gradually approach the hopper 20 on the unloading frame 110 by moving relative to the unloading frame 110 along the third direction z, and unload the steel bars in the hopper 20. At the same time, the rotation of the unloading component 500 around the third direction z can realize the unloading of steel bars at various locations in the hopper 20, thereby improving the unloading efficiency of steel bars.
[0056] Specifically, in this embodiment, the hopper changing device 10 further includes a first driving member (not shown), which is connected to the first conveyor 120 and is used to drive the first conveyor 120 to rotate around the second direction y; the hopper changing device 10 further includes a second driving member (not shown), which is connected to the second conveyor 130 and is used to drive the second conveyor 130 to rotate around the second direction y; the hopper changing device 10 further includes a third driving member (not shown), which is connected to the third conveyor 230 and is used to drive the third conveyor 230 to rotate around the second direction y; the hopper changing device 10 further includes a fourth driving member (not shown), which is connected to the lifting member 220 and is used to drive the lifting member 220 to move along the third direction z.
[0057] The following example illustrates the operation of the hopper changing device 10 of this application, assuming that neither the first conveyor 120 nor the second conveyor 130 has a hopper 20 placed on it, and the hopper 20 is first placed on the first conveyor 120:
[0058] First, during the steel bar production process, a full hopper 20 is placed on a transfer frame 300. Then, a transfer component 210 moves along a first direction x into a clearance space 310. A lifting component 220 moves a third transfer component 230 along a third direction z until it contacts the hopper 20 on the transfer frame 300, thereby lifting the hopper 20 along the third direction z and separating it from the transfer frame 300. Then, the transfer component 210 moves along the first direction x... The direction x moves toward the unloading rack 110. When the transfer component 210 moves to the side of the unloading rack 110 along the first direction x, the lifting component 220 moves the full hopper 20 along the third direction z to the first conveyor 120. The full hopper 20 is transferred to the first conveyor 120 by the rotation of the first conveyor 120 and the third conveyor 230 around the second direction y. Then, the unloading component 500 unloads the steel bars in the hopper 20 on the first conveyor 120.
[0059] Secondly, during the process of unloading the steel bars in the hopper 20 on the first conveyor 120 by the unloading component 500, the transfer component 200 can repeat the above process to transfer another full hopper 20 to the second conveyor 130.
[0060] Furthermore, after the steel bars in the hopper 20 on the first conveyor 120 are unloaded, the third conveyor 230 can be moved along the third direction z to the first conveyor 120 by the lifting member 220, and the empty hopper 20 on the first conveyor 120 can be transferred to the third conveyor 230 by the rotation of the first conveyor 120 and the third conveyor 230 around the second direction y, so that the unloading member 500 can unload the steel bars in the hopper 20 on the second conveyor 130.
[0061] Repeating the above operations can improve the unloading process of steel bars and reduce the impact of the unloading process on other processes in the steel bar production process, thereby improving the production efficiency of steel bars.
[0062] The steel bar production equipment involved in this application embodiment includes: the above-mentioned silo replacement device 10.
[0063] In the steel bar production equipment of this application, since the hopper replacement device 10 of this application can improve the unloading process of steel bars, the steel bar production equipment of this application can have higher production efficiency.
