Description

Technical Field

[0001] This invention belongs to the field of grain brewing technology, specifically relating to an automatic feeding system for a group of fermentation pits. Background Technology

[0002] Currently, the fermentation process of condiments such as soy sauce and vinegar, as well as alcoholic beverages, all require grains to be fermented in a group of fermentation pits after the grains have been made into koji (fermentation starter). Typically, a group of fermentation pits consists of several pit units arranged in an array. A feeding cart is used to evenly distribute the material along each pit unit. There are usually two ways to add material to the feeding cart during the feeding process. One method involves multiple people working together to move the conveying pipe and follow the feeding cart. The disadvantage of this method is that it is labor-intensive and can easily cause dead bends in the conveying pipe during the handling process, leading to material blockage. The other method is that the conveying pipe is fixed, and the feeding cart returns to the outlet of the conveying pipe at regular intervals to add material. The disadvantage of this method is that the feeding cart has too much ineffective travel, which not only makes the route planning of the feeding cart complicated and difficult to control, but also seriously affects the feeding efficiency of the fermentation pit group. Summary of the Invention

[0003] This invention provides an automatic material distribution system for a group of pits, which aims to reduce the labor intensity of material distribution in the pit group and improve the efficiency of material distribution.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic material distribution system for a pit complex is provided, comprising a overhead rail, a first gantry crane and a second gantry crane, a material distribution carriage, two steering mechanisms, and a material distribution tube; wherein, the overhead rail is arranged above both sides of the pit complex; the first gantry crane and the second gantry crane respectively span across the pit complex and are connected to the overhead rail, the traveling speed of the first gantry crane being twice the traveling speed of the second gantry crane; the material distribution carriage is laterally slidably connected to the first gantry crane and follows the longitudinal movement of the first gantry crane; the two steering mechanisms are respectively located at the lateral ends of the second gantry crane; the material distribution tube is arranged along the overhead rail on one side of the pit complex, the material distribution tube sequentially passes around the two steering mechanisms and is fixedly connected to the first gantry crane, and the material distribution tube is connected to the material distribution carriage; a drag chain is connected to the material distribution tube, the drag chain being used to cooperate with the two steering mechanisms to guide the material distribution tube to bend and turn.

[0005] In conjunction with the first aspect, in one possible implementation, the aforementioned automatic material distribution system for the pit group further includes two sets of guide chain mechanisms respectively suspended and fixed above the overhead rails on both sides of the pit group; the guide chain mechanism includes a hanger and several guide chain frames arranged longitudinally at intervals on the hanger; wherein, one end of the guide chain frame is suspended and provided with a guide groove, and each link of the drag chain is provided with a guide component suitable for sliding into the guide groove.

[0006] In some embodiments, each guide chain frame is rotatably connected to the hanger, and each guide chain frame has a downwardly extending swing arm at its end away from its guide groove, and the part of the guide chain frame that is off its rotation axis overlaps and is supported by the hanger; both ends of the first gantry are provided with longitudinally extending guide rods; wherein, when the guide rods abut against the swing arms as the first gantry moves, the suspended ends of the swing arms flip upward to disengage the guide groove from the drag chain.

[0007] For example, the lower end of the swing arm is provided with a roller, and both ends of the guide rod are provided with guide ramps. The side wall of the guide rod located between the two guide ramps forms a limiting surface. The guide ramps are used to guide the roller to roll into or out of the limiting surface to drive the swing arm to swing.

[0008] For example, the gantry is equipped with a support platform, and both the first gantry and the second gantry have a load-bearing platform that is level with the support platform; each link of the cable chain is equipped with a support plate at its bottom, and several casters for rolling the support platform and the load-bearing platform are arranged in an array on the support plate.

[0009] In conjunction with the first aspect, in one possible implementation, the steering mechanism includes a bogie, a rotary drive, and a steering chain; the bogie is fixedly connected to the second gantry, the rotary drive is fixedly connected to the bogie, the steering chain is connected to the output end of the rotary drive, and the edge of the steering chain has a number of slots evenly distributed around it; each link of the drag chain is provided with a guide wheel suitable for embedding in the slot, and the guide wheel is suitable for rolling into the guide groove.

[0010] In some embodiments, the rotary drive includes a slide, a swivel, and a drive motor; the slide is longitudinally slidably connected to the bogie and an elastic buffer is provided between the slide and the bogie; the swivel is rotatably connected to the slide and coaxially connected to the steering chain; the drive motor is fixed to the slide and is drively connected to the swivel to drive the swivel to rotate.

[0011] For example, the steering chain includes a ring seat and a face plate coaxially fixed on the ring seat. The diameter of the face plate is larger than the diameter of the ring seat, and the edge of the face plate is provided with a groove. Each link of the drag chain is provided with a lateral support wheel, which is used to roll the peripheral wall of the support ring seat.

[0012] For example, each link of the cable chain has a top plate, which is connected to the support plate by several spaced uprights; the fabric tube passes between the top plate and the support plate and has at least one upright on each side; the lateral support wheel is rotatably connected to the upright located on the curved inner side of the fabric tube; adjacent links are connected by a tie rod hinged to the top plate.

[0013] In some embodiments, the first gantry is equipped with a movable material pipe, one end of which is connected to the feeding port of the placing vehicle, and the other end is connected to the placing pipe.

[0014] The beneficial effects of the automatic concrete placement system for pit groups provided by this invention are as follows: Compared with the prior art, the automatic concrete placement system for pit groups of this invention utilizes overhead rails installed above both sides of the pit group to mount a first gantry crane and a second gantry crane. The concrete placement tube is laid along the overhead rails and forms a dynamic path around the second gantry crane and fixed to the first gantry crane based on the cooperation of the cable chain and two steering mechanisms. When the first gantry crane drives the concrete placement vehicle to move synchronously, the first gantry crane simultaneously tractions the concrete placement tube, while the second gantry crane follows the first gantry crane at half the speed of the first gantry crane. In this way, the second gantry crane can be shaped... It functions similarly to a movable pulley, ensuring that the placing tube remains taut on the overhead rail and that materials can be added to the placing cart at any time without manual dragging. This not only saves labor and reduces labor intensity but also avoids ineffective travel of the placing cart, improving placing efficiency. Furthermore, because the placing tube can achieve stable bending and steering through the cooperation of the connected drag chain and steering mechanism, it avoids dead bends in the bending parts of the placing tube that could cause material blockage, thereby improving the smoothness of the placing operation and further promoting the improvement of placing efficiency.

Detailed Implementation

[0027] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0028] It should be noted that when an element is referred to as being "set on" or "connected to" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "lateral," "longitudinal," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0029] Please refer to the following: Figures 1 to 11The automatic material distribution system for pit groups provided by the present invention will now be described. The automatic material distribution system for the pit complex includes a ceiling track 30, a first gantry 10 and a second gantry 20, a material distribution carriage 40, two steering mechanisms 50, and a material distribution tube 60. The ceiling track 30 is positioned above both sides of the pit complex 90. The first gantry 10 and the second gantry 20 span across the pit complex 90 and are connected to the ceiling track 30, with the first gantry 10 traveling at twice the speed of the second gantry 20. The material distribution carriage 40 is laterally slidably connected to the first gantry 10 and moves longitudinally with it. The two steering mechanisms 50 are located at the lateral ends of the second gantry 20. The material distribution tube 60 is laid along the ceiling track 30 on one side of the pit complex 90, successively passing around the two steering mechanisms 50 and fixedly connected to the first gantry 10, and is also connected to the material distribution carriage 40. A drag chain 70 is connected to the material distribution tube 60, which cooperates with the two steering mechanisms 50 to guide the material distribution tube 60 to bend and turn.

[0030] It should be understood that, as prior art, the overhead rail 30 in this embodiment can be understood as a track with a certain suspended height. Its installation foundation can be a load-bearing wall or column in the fermentation workshop, or a gantry load-bearing beam spanning above the fermentation pit group 90 in the fermentation workshop, and is not limited here. There are two overhead rails 30, which are respectively set on both sides of the fermentation pit group 90. The two ends of the first gantry 10 and the second gantry 20 are respectively connected to one of the overhead rails 30. The first gantry 10 and the second gantry 20 each have a power system to drive themselves to move along the overhead rail 30. It can also be considered that the first gantry 10 and the second gantry 20 are both overhead cranes commonly found in industrial workshops. Furthermore, the fabric placing cart 40 used in this embodiment is the same as the existing fabric placing cart 40. It is only necessary to connect the fabric placing pipe 60 to the feeding port of the fabric placing cart 40. The fabric placing cart 40 can be self-driven or passively driven by the first gantry 10. Since the pit group 90 is usually composed of several pit units arranged in a longitudinal and transverse array, the travel trajectory of the fabric placing cart 40 in this embodiment can be to first align the pit units in one column, and then the fabric placing cart 40 will place the fabric in each pit unit in the column from front to back. After the fabric is placed in each pit unit in the column, it will move laterally to the next column and move in the opposite direction to place the fabric from back to front. This process is repeated until the fabric is placed in the entire pit group 90. The fabric placing cart 40 can also place the fabric laterally first and then move back and forth. This is not limited here.

[0031] The working principle of the automatic material distribution system for the pit group provided in this embodiment can be combined with... Figure 1It is understood that the two steering mechanisms 50 are located at the two lateral ends of the second gantry 20 and cooperate with the drag chain 70 on the fabric tube 60. The cooperation between the steering mechanism 50 and the drag chain 70 can be understood as a chain drive. The bending guidance of the fabric tube 60 by the two steering mechanisms 50 can make the fabric tube 60 form a U-shape. The second gantry 20 as a whole is equivalent to a movable pulley (the traveling distance of the first gantry 10 is equal to the sum of the traveling lengths of the fabric tubes 60 on both sides of the second gantry 20). Therefore, the traveling speed of the first gantry 10 is configured to be twice that of the second gantry 20, so that the fabric tube 60 is always in a taut state. Moreover, although the bending position of the fabric tube 60 is constantly changing, it can always achieve turning in an arc bending shape under the bending guidance of the steering mechanism 50. Therefore, it can avoid the phenomenon of dead bend when the fabric tube 60 bends and changes direction.

[0032] The automatic material distribution system for the pit complex provided in this embodiment, compared with the prior art, utilizes overhead rails 30 installed above both sides of the pit complex 90 to mount a first gantry 10 and a second gantry 20. The material distribution pipe 60 is laid along the overhead rails 30 and forms a dynamic path around the second gantry 20 and fixed to the first gantry 10 based on the cooperation of the drag chain 70 and two steering mechanisms 50. When the first gantry 10 drives the material distribution vehicle 40 to move synchronously, the first gantry 10 simultaneously pulls the material distribution pipe 60, while the second gantry 20 follows the first gantry 10 at half the speed of the first gantry 10. In this way, the second gantry 20 can be shaped into a fixed path. It functions similarly to a movable pulley, ensuring that the placing tube 60 remains taut on the overhead rail 30 and can be loaded with material into the placing cart 40 at any time without manual dragging of the placing tube 60. This not only saves labor and reduces labor intensity but also avoids ineffective travel of the placing cart 40, improving placing efficiency. Furthermore, since the placing tube 60 can achieve stable bending and steering through the cooperation of the drag chain 70 and the steering mechanism 50, it can prevent dead bends in the bending parts of the placing tube 60 that could lead to material blockage, thereby improving the smoothness of the placing operation and further promoting the improvement of placing efficiency.

[0033] In some embodiments, see Figure 1 , Figure 6 and Figure 8 The aforementioned automatic material distribution system for the cellar group also includes two sets of guide chain mechanisms 80, which are respectively suspended and fixed above the overhead rails 30 on both sides of the cellar group 90. The guide chain mechanism 80 includes a hanger 81 and several guide chain frames 82 that are longitudinally spaced on the hanger 81. One end of the guide chain frame 82 is suspended and has a guide groove 821. Each link of the drag chain 70 is provided with a guide component suitable for sliding into the guide groove 821.

[0034] The mounting base for the hanger 81 can be the same as that for the overhead rail 30, such as being fixed to a load-bearing wall or column structure in the fermentation workshop, or to a gantry beam above the pit complex 90; no limitation is made here. The aforementioned guide component can be a guide block with a width smaller than the width of the guide groove 821, or it can be a guide wheel 71 set on the chain link (here, the guide wheel 71 cooperates with both the guide groove 821 and the slot 530 of the steering mechanism 50). The hanger 81 serves as the mounting base for the guide chain frame 82, with one end of the guide chain frame 82 suspended to provide sufficient space. Based on this, the guide groove 821 guides each link of the drag chain 70, thereby enabling the drag chain 70 to always move along the trajectory of the guide groove 821, thus allowing the drag chain 70 to stably constrain the material distribution pipe 60 and ensure smooth material flow within the material distribution pipe 60.

[0035] For some possible implementations, please refer to [link / reference]. Figures 8 to 10 Each guide chain frame 82 is rotatably connected to the hanger 81, and each guide chain frame 82 has a downwardly extending swing arm 822 at its end away from its guide groove 821. The part of the guide chain frame 82 that is off its rotation axis overlaps and is supported by the hanger 81. Both ends of the second gantry 20 are provided with longitudinally extending guide rods 21. When the guide rod 21 abuts against the swing arm 822 as the second gantry 20 moves, the suspended end of the swing arm 822 flips upward to disengage the guide groove 821 from the drag chain 70.

[0036] The guide frame 82 is rotatably connected to the hanger 81, allowing for vertical rotation. In its normal state, the guide frame 82 maintains its middle section overlapping the hanger 81 based on the gravity of its suspended end, thus guiding the cable chain 70. As the first gantry 10 and the second gantry 20 travel, each link on the cable chain 70 passes through the two steering mechanisms 50 in sequence. When passing through the steering mechanism 50, the cable chain 70 needs to disengage from the guide groove 821. Therefore, a swing arm 822 is provided on the guide frame 82, and a guide rod 21 is provided on the second gantry 20. The guide rod 21 abuts against the swing arm 822, causing the suspended end of the guide frame 82 to rotate upward. This makes the guide groove 821 higher than the cable chain 70, ensuring that the cable chain 70 can smoothly pass through the steering mechanism 50 and achieve bending and turning. This avoids the problem that the cable chain 70 cannot disengage from the guide groove 821 and thus cannot enter the steering mechanism 50 for smooth turning, thereby improving the bending and reversing stability of the fabric tube 60.

[0037] Specifically, please combine Figures 8 to 10 In this embodiment, the lower end of the swing arm 822 is provided with a roller 8221, and both ends of the guide rod 21 are provided with guide slopes 211. The side wall of the guide rod 21 located between the two guide slopes 211 forms a limiting surface 212. The guide slopes 211 are used to guide the roller 8221 to roll into or out of the limiting surface 212 to drive the swing arm 822 to swing.

[0038] When the second gantry 20 moves, the guide rod 21 contacts the rollers 8221 at the lower end of each swing arm 822 in sequence, causing the rollers 8221 to roll from the guide ramp 211 at one end of the guide rod 21 to the limiting surface 212. During this process, the swing arm 822 can be driven to swing, thereby causing the guide groove 821 to get rid of the drag chain 70. When the rollers 8221 roll to the other end of the guide rod 21, the corresponding chain link has already been released from the constraint range of the guide groove 821 under the guidance of the steering mechanism 50. Therefore, the rollers 8221 roll away from the limiting surface 212 along another guide ramp 211, thereby causing the swing arm 822 to automatically reset under the gravity of its own suspended end. The automatic flipping of the guide chain frame 82 is achieved purely from the mechanical structure without the need for electronic control components, and the operation is highly reliable.

[0039] In some embodiments, see Figure 5 , Figure 7 and Figure 8 The gantry 81 is equipped with a support platform 811, and the first gantry 10 and the second gantry 20 both have a load-bearing platform 11 that is flush with the height of the support platform 811; wherein, each link of the drag chain 70 is equipped with a support plate 72 at the bottom, and several casters 721 for rolling the support platform 811 and the load-bearing platform 11 are arranged in an array on the support plate 72.

[0040] The casters 721 roll the support platform 811 and the load-bearing platform 11 to provide stable support for the cable chain 70, thereby providing support for the fabric delivery tube 60. This not only ensures the ease of movement of the fabric delivery tube 60, thus preventing it from bearing excessive traction, but also prevents the fabric delivery tube 60 from becoming too long and bending under the force of gravity. This ensures the stability of the cooperation between the cable chain 70 and the guide groove 821, and thus ensures the posture stability of the fabric delivery tube 60.

[0041] As one specific embodiment of the steering mechanism 50 described above, please refer to Figure 11 The steering mechanism 50 includes a bogie 51, a rotary drive 52, and a steering chain 53. The bogie 51 is fixedly connected to the second gantry 20, the rotary drive 52 is fixedly connected to the bogie 51, and the steering chain 53 is connected to the output end of the rotary drive 52. The edge of the steering chain 53 is evenly distributed with several slots 530. Each link of the drag chain 70 is provided with a guide wheel 71 suitable for embedding in the slot 530, and the guide wheel 71 is suitable for rolling into the guide groove 821.

[0042] The rotary drive component 52 can be a motor, hydraulic motor, or pneumatic motor. It directly or indirectly drives the steering chain 53 to rotate, causing the guide wheel 71 embedded in the slot 530 to actuate the corresponding chain link. This constrains the fabric tube 60 to the corresponding link, completing the bending and reversing process. This design is not only simple and reliable in its overall structure, but the cooperation between the guide wheel 71 and the slot 530 prevents slippage of the fabric tube 60 during bending and reversing, thus improving the stability of the fabric tube 60. Furthermore, the guide wheel 71, in conjunction with the guide groove 821, also serves as a guide component, constraining the travel trajectory of the drag chain 70. This not only improves the compactness of the motion cooperation structure between each chain link and the guide groove 821, but also reduces the relative motion resistance between the chain link and the guide groove 821, thereby improving the stability of the fabric placement process.

[0043] Optionally, see Figure 11 In this embodiment, the rotary drive component 52 includes a slide 521, a swivel 522, and a drive motor 523. The slide 521 is longitudinally slidably connected to the bogie 51 and an elastic buffer 54 is provided between the slide 521 and the bogie 51. The swivel 522 is rotatably connected to the slide 521 and coaxially connected to the steering chain 53. The drive motor 523 is fixed to the slide 521 and is drively connected to the swivel 522 to drive the swivel 522 to rotate.

[0044] The drive motor 523 is connected to the slide 521 and can maintain stable drive to the turntable 522 when the slide 521 moves. The elastic buffer 54 can be a rubber buffer pad or a spring. By setting the elastic buffer 54, the slide 521 can form a flexible connection on the bogie 51. In this way, when the fabric tube 60 bends and changes direction around the steering chain 53, the slide 521 can be driven to swing flexibly based on the magnitude of the traction force on the fabric tube 60. On the one hand, this avoids the fabric tube 60 from being damaged due to excessive force, and on the other hand, it avoids jamming between the drag chain 70 and the steering chain 53, thereby ensuring the smoothness and stability of the fabric operation.

[0045] Specifically, such as Figure 11 As shown, a worm gear 5211 is rotatably connected to the slide 521, and one end of the worm gear 5211 is connected to the drive motor 523. A worm wheel 5221 is mounted on the rotary seat 522, and the worm wheel 5221 meshes with the worm gear 5211. The drive motor 523 drives the worm gear 5211 to rotate, which in turn drives the worm wheel 5221 to rotate, ultimately enabling the steering chain 53 to rotate with the rotary seat 522. The transmission method is simple, compact, and highly reliable.

[0046] As one specific structural form of the aforementioned steering chainring 53, please refer to Figure 11The steering chain 53 includes a ring seat 531 and a face plate 532 coaxially fixed on the ring seat 531. The diameter of the face plate 532 is larger than the diameter of the ring seat 531, and the edge of the face plate 532 is provided with a groove 530. Each link of the drag chain 70 is provided with a lateral support wheel 73, which is used to roll and support the peripheral wall of the ring seat 531. The face plate 532 is used to achieve meshing connection with each link. Considering that the fabric tube 60 has a large lateral force on the steering chain 53 during bending and reversing, a ring seat 531 with a smaller diameter is provided below the face plate 532. On the one hand, the ring seat 531 is used to achieve a fixed connection with the swivel seat 522. On the other hand, the peripheral wall of the ring seat 531 serves as a circumferential support surface to provide rolling support for the lateral support wheel 73 on the link, thereby improving the bending and reversing stability of the fabric tube 60.

[0047] For some possible implementations, please refer to [link / reference]. Figure 5 Each link of the cable chain 70 has a top plate 74, which is connected to the support plate 72 by a number of spaced uprights 75. The fabric tube 60 passes between the top plate 74 and the support plate 72, and each side of the fabric tube 60 has at least one upright 75. The lateral support wheel 73 is rotatably connected to the upright 75 located on the curved inner side of the fabric tube 60. Adjacent links are connected by a pull rod 76 hinged to the top plate 74 and the support plate 72.

[0048] Four uprights 75 can be used to connect the top plate 74 and the support plate 72 into a single link. This allows the fabric tube 60 to have two uprights 75 on each side for horizontal radial constraint, while the top plate 74 and the support plate 72 provide vertical diameter constraint on the fabric tube 60. This not only prevents the fabric tube 60 from slipping off the link but also ensures the flexibility of the fabric tube 60 when bending between the top plate 74 and the support plate 72. Furthermore, the uprights 75 serve as the mounting base for the lateral support wheels 73, thereby improving the structural compactness and motion stability of the link. The links of the drag chain 70 are connected by tie rods 76. Both ends of the pull rod 76 are hinged to adjacent chain links, and each chain link has a hinge point at both ends. The distance between the two hinge points is the same as the distance between the two hinge points of the pull rod 76, which ensures the bending flexibility between adjacent chain links. Furthermore, a guide wheel 71 is installed on each hinge point at both ends of the chain link. The guide wheel 71 and the pull rod 76 can share the same shaft for connection. The distribution spacing of the slots 530 on the face plate 532 matches the center distance of the adjacent guide wheels 71, which ensures the meshing stability between each chain link and the face plate 532, thereby improving the bending and turning stability of the fabric tube 60.

[0049] It should be noted that you should refer to [link / reference]. Figure 2 and Figure 7The first gantry crane 10 is equipped with a movable material pipe 61. One end of the movable material pipe 61 is connected to the feeding port of the placing cart 40, and the other end is connected to the placing tube 60. The movable material pipe 61 can be understood as an extension of the placing tube 60. At the same time, the movable material pipe 61 is also equipped with a chain link with casters 721, so that the movable material pipe 61 can move flexibly on the load-bearing platform 11 of the first gantry crane 10 as the lateral position of the placing cart 40 changes, thereby realizing automated material placement of the pit group 90.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
