Description

Technical Field

[0001] This application relates to the field of transfer bucket equipment, and in particular to a transfer bucket conveying lifting device. Background Technology

[0002] In the alcoholic beverage production process, the transfer of lees is a crucial step connecting the distillation process with subsequent processing stages. Traditional distilleries use manual handling or simple carts to transfer lees, which is labor-intensive, inefficient, and prone to spillage and contamination. Modern brewing workshops generally employ specialized transfer bucket hoisting devices, using cranes in conjunction with detachable transfer buckets to achieve efficient lees transfer. This device not only ensures the lees remain sealed during transfer, preventing alcohol evaporation and external contamination, but also adapts to the high-temperature and high-humidity brewing environment, meeting food-grade hygiene requirements.

[0003] Existing transfer bucket lifting devices typically consist of a frame, a base, a detachable transfer bucket, and clamping components. The frame serves as the main load-bearing structure, with lifting lugs at the top for connection to a crane. The base, housed within the machine body, supports the transfer bucket. The clamping and fixing mechanism mainly includes hydraulic cylinders fixed to both sides of the frame, with locking blocks fixed to the telescopic ends of the cylinders. Locking holes, matching the locking blocks, are provided on the side walls of both the base and the transfer bucket. During operation, the operator first places the transfer bucket on the base, then controls the hydraulic cylinders to extend, causing the locking blocks to insert into the locking holes on the base and the side walls of the transfer bucket. Mechanical interlocking quickly fixes the transfer bucket in place. After fixing, the transfer bucket is transported via trusses or other devices installed in the storage area.

[0004] For existing transfer bucket conveyor lifting devices, the hydraulic cylinder requires sufficient extension and retraction stroke to ensure that the locking block can be inserted into the locking hole of the transfer bucket, which significantly increases the width of the entire frame. In practical applications, the excessively large frame size not only increases the equipment manufacturing cost but also leads to difficulties in transportation and storage, especially in space-constrained old brewery buildings where large frames have poor maneuverability. Utility Model Content

[0005] To address the issues of large size and poor versatility of existing transfer bucket lifting devices, this application provides a transfer bucket conveying lifting device.

[0006] The transfer bucket conveying lifting device provided in this application adopts the following technical solution: A transfer bucket conveying lifting device includes a frame, a base on the frame, a transfer bucket inside the base, lifting lugs on the frame, two locking blocks on opposite side walls of the base, locking holes for interlocking with the locking blocks on the side walls of the base and the transfer bucket, two slide rails on opposite side walls of the base, mounting plates slidably mounted on the slide rails, the locking blocks mounted on the mounting plates, a movable plate between the two mounting plates, and a driving component on the frame for moving the movable plate.

[0007] By adopting the above technical solution, during the hoisting and transportation of the transfer bucket, the transfer bucket is placed in the base, and then the base is fixed to the frame. The drive unit drives the moving plate to move along the width direction of the frame. The moving plate drives the mounting plate to move on the slide rail. The locking block on the mounting plate is inserted into the locking hole of the base and the transfer bucket, so that the base is fixed to the frame. The two locking blocks fixed on the symmetrical side wall of the base improve the stability during the hoisting process and make it difficult for the lees in the transfer bucket to spill out of the transfer bucket. The driving component is used to fix the base and transfer bucket by driving the locking block. Compared with the existing technology that uses hydraulic cylinders for locking, the driving component reduces the overall size of the frame, allowing the transfer bucket to be transported to the edge of the lees warehouse, thus improving the convenience of transportation.

[0008] Optionally, the driving component includes a lead screw rotatably mounted on the frame, a movable plate threadedly connected to the lead screw, motors mounted on opposite sides of the frame, a first bevel gear coaxially fixed to the output end of the motor, a first driven wheel meshing with the first bevel gear fixed to the end of the lead screw, the rotation axis of the motor output end being parallel to the height direction of the frame, and the motor output end being close to the bottom of the frame.

[0009] By adopting the above technical solution, when fixing the base and the transfer hopper, the motor is started. The motor rotates, driving the first bevel gear to rotate. The first bevel gear meshes with the first driven wheel and drives the lead screw to rotate. The rotation of the lead screw drives the moving plate to move along the width direction of the frame. The mounting plate on the moving plate moves with the moving plate, causing the locking plate on the mounting plate to move along the slide rail, so that the locking block is inserted into the locking holes of the base and the transfer hopper, thereby fixing the base to the frame. By driving the lead screw to rotate, the lead screw drives the locking block to fix the base. Compared with the existing technology that uses a hydraulic cylinder to fix the base, the rotation direction of the motor output end is parallel to the height direction of the frame, which reduces the overall volume of the frame, reduces manufacturing costs, and allows the transfer hopper to be closer to the edge of the warehouse, effectively improving the handling effect of the lees.

[0010] Optionally, a limiting block is fixedly connected to the end of the lead screw away from the motor, and the limiting block is movably fitted against the side wall of the transfer bucket.

[0011] By adopting the above technical solution, during the movement of the moving plate driven by the lead screw, the locking block is inserted into the locking hole. After the locking block is locked in place, the limiting block abuts against the side wall of the transfer bucket. The contact area between the limiting block and the transfer bucket is large. Compared with the end of the lead screw directly abutting against the side wall of the transfer bucket, the limiting block reduces the damage to the transfer bucket and also reduces the excessive insertion of the locking block into the locking hole.

[0012] Optionally, the frame is further provided with a sealing assembly for sealing the transfer hopper. The sealing assembly is a folding sealing plate that is telescopically disposed on both sides of the frame. The folding sealing plate is movably fitted with the top of the transfer hopper. The direction of movement of the folding sealing plate is parallel to the length direction of the frame. Threaded rods are rotatably disposed on both sides of the frame, and the two threaded rods are arranged alternately. One end of the folding sealing plate rotates on the frame, and the other end of the folding sealing plate is rotatably disposed with a slider. The slider is threadedly connected to the threaded rod. The sealing assembly also includes a synchronizing element for driving the threaded rod to rotate.

[0013] By adopting the above technical solution, when there is a large amount of lees in the transfer hopper, the lees are prone to spilling out of the transfer hopper during the hoisting process, polluting the environment and increasing cleaning costs. At the same time, the lees in the transfer hopper are easily oxidized and deteriorated when exposed to air, affecting the quality of subsequent brewing. When the motor drives the first bevel gear to rotate, it simultaneously drives the synchronizing component to operate. The synchronizing component drives the threaded rod to rotate, and the threaded rod drives the slider to move along the length of the machine body. The slider drives the folding sealing plate to move along the length of the frame. The synchronizing components located on both sides of the frame drive the two sealing plates to move towards the middle of the transfer hopper. When the locking rod is inserted into the locking hole, the ends of the two sealing plates fit together, sealing the opening of the transfer hopper. When the transfer hopper is hoisted, the sealing plate reduces the risk of dust and impurities in the storage room falling into the lees, reduces the risk of lees spilling out of the transfer hopper, and maintains the temperature stability inside the transfer hopper, reducing the impact of external temperature on the lees.

[0014] Optionally, the synchronizing element is a second bevel gear disposed at the output end of the motor. The output end of the motor is close to the top of the frame. A transmission rod is rotatably disposed on the frame. Both ends of the transmission rod are coaxially fixed with transmission gears. A second driven wheel is coaxially fixed in the middle of the transmission rod. The two transmission gears mesh with the second bevel gear and the second driven wheel, respectively.

[0015] By adopting the above technical solution, when the motor starts, the motor rotates and drives the second bevel gear to rotate. The second bevel gear meshes with the transmission gear on the transmission rod near the motor end, and drives the transmission rod to rotate. The transmission gear on the transmission rod away from the motor end meshes with the second driven wheel. The rotation of the transmission rod drives the threaded rod to rotate, so that the threaded rod drives the slider to move along the length of the frame.

[0016] Optionally, the frame is provided with a sliding groove, and the end of the folding sealing plate is fixedly connected to a roller that slides and fits in contact with the sliding groove.

[0017] By adopting the above technical solution, when the slider drives the folding sealing plate to move, the rollers on the folding sealing plate move along the sliding groove on the side wall of the frame, which improves the stability of the folding sealing plate during the movement process.

[0018] Optionally, a limiting rod is fixedly connected to the frame, and a limiting plate is rotatably provided at the end of the sealing plate away from the threaded rod, with the limiting plate slidably disposed on the limiting rod.

[0019] By adopting the above technical solution, during the rotation of the threaded rod and the movement of the slider, the limiting plate located on the end of the folding sealing plate away from the threaded rod moves on the limiting rod, so that the longer end of the folding sealing plate is parallel to the width direction of the frame, making the folding sealing plate less prone to tilting and improving the sealing effect of the folding sealing plate on the opening of the transfer bucket.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to use the transfer bucket to lift the lees, the motors located on both sides of the frame are started through the control cabinet. The rotation of the motor drives the first bevel gear to rotate, which in turn drives the lead screw to rotate. The rotation of the lead screw drives the moving plate to move, so that the locking block on the mounting plate is inserted into the locking hole of the base and the transfer bucket, thereby fixing the base and the transfer bucket to the frame. Using the motor to drive the lead screw to rotate to fix the base and the transfer bucket to the frame reduces the overall volume of the frame and saves the manufacturing cost of the frame. At the same time, it allows the transfer bucket to be lifted to the edge of the warehouse, improving the convenience of transportation. 2. While the motor drives the first bevel gear to rotate, it also drives the second bevel gear to rotate, causing the transmission rod to rotate. The transmission rod drives the threaded rod to rotate, and the rotation of the threaded rod causes the slider to move. This causes the two folding sealing plates located on the frame to move towards the center of the transfer hopper, thereby sealing the transfer hopper with the folding sealing plates. This reduces the risk of the lees spilling out of the transfer hopper, reduces the risk of impurities falling into the transfer hopper, reduces the impact of external temperature on the lees in the transfer hopper, and improves the quality of subsequent brewing.

[0022] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0023] Example 1

[0024] This application discloses a transfer bucket conveying lifting device. (Refer to...) Figure 1-3 The transfer bucket conveying lifting device includes a frame 1, a base 2 on the frame 1, a transfer bucket 3 for holding wine lees on the base 2, a lifting lug 11 on the top of the frame 1, two slide rails 43 fixedly connected to the opposite side walls of the frame 1, a mounting plate 44 slidably mounted on the slide rails 43, a cylindrical locking block 41 threaded or integrally formed on the mounting plate 44, a moving plate 45 threaded or integrally formed between the two locking blocks 41, a locking hole 42 for inserting and matching the locking block 41 on the side walls of the base 2 and the transfer bucket 3, and a driving component 46 for driving the moving plate 45 on the frame 1. The driving component 46 is a motor 461 fixedly connected to the frame 1. The frame 1 is located on one side of the motor 461 along its length. The rotation shaft of the output end of the motor 461 is parallel to the height direction of the frame 1, and the output end of the motor 461 is close to the bottom of the frame 1. A control cabinet for controlling the motor 461 is provided on the machine body. A first bevel gear 462 is coaxially fixedly connected to the output end of the motor 461. A lead screw 464 is rotatably provided on the frame 1. A first driven wheel 463 is coaxially fixedly connected to the end of the lead screw 464 near the motor 461. The first driven wheel 463 meshes with the first bevel gear 462. A differential gearbox is provided between the lead screw 464 and the motor 461. A limit block 47 is provided at the end of the lead screw away from the motor 461. The limit block 47 is movably fitted against the side wall of the transfer bucket 3.

[0025] During the hoisting of the transfer bucket 3, the frame 1 is lowered from the truss to the same height as the base 2. After the frame 1 and base 2 are pre-fixed, the motor 461 is started via the control cabinet. The rotation of the motor 461 drives the first bevel gear 462 to rotate. The first bevel gear 462 meshes with the first driven wheel 463. The motor 461 drives the lead screw 464 to rotate. The differential gearbox on the lead screw 464 can reduce the speed of the lead screw 464 while increasing the torque of the lead screw 464. The rotation of the lead screw 464 drives the moving plate 45, which is threadedly connected to the lead screw 464, to move along the width direction of the frame 1. The mounting plate 44 on the moving plate 45 moves simultaneously with the moving plate 45, and the locking block 41 on the mounting plate 44 moves along the slide rail 43. The locking block 41 is inserted into the locking hole 42 on the side wall of the base 2 and the transfer bucket 3, thereby fixing the base 2 to the frame 1. Subsequently, the frame... The lifting lug 11 on the frame 1 lifts the transfer bucket 3, transporting the lees in the transfer bucket 3 to the designated position. The motor 461 drives the lead screw 464 to rotate, causing the locking block 41 to insert into the locking hole 42, fixing the base 2 and the transfer bucket 3 to the frame 1. Compared with the prior art, which uses a hydraulic cylinder to fix the base 2 and the transfer bucket 3, this device reduces the overall volume of the frame 1 and reduces manufacturing costs. At the same time, during the lifting and transfer of the transfer bucket 3, it shortens the distance between the transfer bucket 3 and the warehouse, improving the transfer efficiency of the transfer bucket 3 in transporting the lees. When the lead screw 464 drives the moving plate 45 to move, the locking block 41 inserts into the locking hole 42. After the locking block 41 is locked in place, the limiting block 47 on the lead screw 464 abuts against the side wall of the transfer bucket 3, reducing the direct contact between the lead screw 464 and the transfer bucket 3, and reducing the risk of the lead screw 464 causing damage to the transfer bucket 3.

[0026] The implementation principle of the transfer bucket conveying hoisting device in this application embodiment is as follows: During the transfer of lees in the warehouse, the transfer bucket 3 is installed on the base 2, and the lees are filled into the transfer bucket 3. Next, the frame 1 is hoisted to the corresponding position, so that the frame 1 is fitted onto the base 2, and the frame 1 and base 2 are pre-fixed. The motors 461 on both sides of the frame 1 are started via the control cabinet. The rotation of the motors 461 drives the first bevel gear 462 to rotate, which in turn drives the lead screw 464 to rotate. The rotation of the lead screw 464 causes the moving plate 45 to move along the width direction of the machine body. The locking block 41 on the mounting plate 44 moves along the slide rail 43, thereby inserting the locking block 41 into the locking hole 42 of the base 2 and the transfer bucket 3, thus fixing the transfer bucket 3, the base 2 and the frame 1 at the same time. Two locking blocks 41 are provided on the frame 1 on the opposite side to improve stability. The motor 461 drives the lead screw 464 to rotate, thereby fixing the base 2 and the transfer bucket 3, reducing the overall volume of the frame 1, and allowing the transfer bucket 3 to be hoisted to the edge position, effectively improving the transfer efficiency of the lees, while saving the manufacturing cost of the frame 1.

[0027] Example 2

[0028] Reference Figure 4-6 The difference between this embodiment and Embodiment 1 is that: the frame 1 is further provided with a sealing assembly for sealing the opening of the transfer hopper 3. The sealing assembly includes folding sealing plates 51 disposed on both sides of the frame 1. A slider 512 and a limiting plate 513 are rotatably disposed at the bottom of the folding sealing plates 51 respectively. A sliding groove 514 is provided on the side wall of the frame 1. Rollers 511 are rotatably disposed at both ends of the folding sealing plates 51. The rollers 511 are movably fitted with the sliding groove 514. The folding sealing plates 51 are movably fitted with the opening of the transfer hopper 3. The moving direction of the folding sealing plates 51 is parallel to the length direction of the frame 1. Threaded rods 52 are rotatably disposed on the opposite side walls of the frame 1. The two threaded rods 52 are staggered along the width direction of the frame 1. The arrangement direction of the threaded rods 52 is parallel to the length direction of the frame 1. The frame 1 is located on the threaded... A limiting rod 53 is fixedly connected to the side wall opposite to the rod 52. The slider 512 is threadedly connected to the threaded rod 52. The limiting plate 513 is slidably disposed on the limiting rod 53. The sealing assembly also includes a synchronizing element for driving the threaded rod 52 to rotate. The synchronizing element is a transmission rod 543 rotatably disposed on the frame 1. Both ends of the transmission rod 543 are coaxially fixedly connected to transmission gears 544. The arrangement direction of the transmission rod 543 is parallel to the width direction of the frame 1. At this time, the rotation axis of the output end of the motor 461 is along the height direction of the frame 1. The output shaft of the motor 461 is close to the top of the frame 1. A second bevel gear 541 is coaxially fixedly connected to the output end of the motor 461. A second driven wheel 542 is provided at the end of the threaded rod 52. The transmission gear 544 on the transmission rod 543 meshes with the second bevel gear 541 and the second driven wheel 542 respectively.

[0029] During the process of fixing the transfer bucket 3 using this device, the control cabinet starts the motor 461. The motor 461 drives the first bevel gear 462 to rotate, which in turn drives the lead screw 464 to rotate. The rotation of the lead screw 464 causes the locking block 41 to insert into the locking hole 42. At the same time, the rotation of the motor 461 drives the second bevel gear 541 to rotate. The second bevel gear 541 engages with the transmission gear 544 on the transmission rod 543, driving the transmission rod 543 to rotate. The transmission gear 544 at the other end of the transmission rod 543 meshes with the second driven wheel 542, driving the threaded rod 52 to rotate. The rotation of the threaded rod 52 causes the slider 512 to move along the threaded rod 52, and causes the limiting plate 513 to slide on the limiting rod 53. The limiting plate 513 and the limiting rod 53 improve the stability of the folding sealing plate 51 during movement. The slider 512 moves and drives the folding sealing plate 51 to move along the length of the frame 1. The two folding sealing plates 51 move towards the center of the hopper. The rollers 511 at both ends of the folding sealing plates 51 slide within the slide groove 514 of the frame 1. The slide groove 514 and the rollers reduce the damage caused by excessive friction between the folding sealing plates 51 and the transfer hopper 3 during the movement. When it is necessary to remove the lees from the transfer hopper 3, the control motor 461 reverses, and the locking block 41 moves away from the locking hole 42. At the same time, the folding sealing plates 51 move to both sides of the frame 1, thereby opening the folding sealing plates 51. This device reduces the risk of lees spilling from the transfer hopper 3, reduces the influence of external temperature on the lees in the transfer hopper 3, and reduces the amount of impurities in the storage room falling into the transfer hopper 3, thus improving the quality of subsequent brewing. Setting the sealing plates on the frame 1 to seal the transfer hopper 3 saves costs and reduces the workload of cleaning the cover compared to directly setting the cover on the transfer hopper 3.

[0030] The implementation principle of the conveying hoist device for the transfer bucket in this embodiment is as follows: During the process of fixing the transfer bucket 3, the control cabinet controls the motor 461 to start. The motor 461 drives the first bevel gear 462 and the second bevel gear 541 to rotate. The rotation of the first bevel gear 462 drives the lead screw 464 to rotate. The lead screw 464 drives the moving plate 45 to move and inserts the locking block 41 on the mounting plate 44 into the locking hole 42, thus completing the fixing of the base 2 and the bucket. At the same time, the second bevel gear 541 rotates and drives the transmission rod 543 to rotate. The rotation of the transmission rod 543 drives the threaded rod 52 to rotate. The rotation of the threaded rod 52 drives the slider. 512 moves along the length of the machine body, causing the folding sealing plates 51 located at both ends of the frame 1 to move towards the center of the transfer hopper 3. The rollers 511 at both ends of the folding sealing plates 51 move in the slide grooves 514 of the frame 1. When the locking block 41 completes locking, the side walls of the two folding sealing plates 51 abut against each other, sealing the transfer hopper 3. This device, while fixing the base 2 and the hopper to the frame 1, also seals the transfer hopper 3 with the folding sealing plates 51, reducing the risk of spillage of the lees during the transfer process, reducing the amount of impurities falling into the transfer hopper 3, and reducing the impact of external temperature on the lees, thus improving the quality of subsequent brewing.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
