Description

Technical Field

[0001] This utility model relates to the field of brewing equipment technology, and in particular to a lees grab bucket device. Background Technology

[0002] Against the backdrop of the rapid development of the modern brewing industry, the efficient treatment of distiller's grains, as a major byproduct of the brewing process, is crucial for improving winery production efficiency and reducing operating costs. With the continuous expansion of brewing scale, traditional manual methods of handling distiller's grains are no longer sufficient to meet the demands, making automated and intelligent distiller's grains handling equipment an inevitable trend in the industry. The distiller's grains grab bucket device, as a key piece of equipment for achieving mechanized distiller's grains transfer, directly affects the efficiency and quality of distiller's grains handling.

[0003] Currently, most common distillery waste grab bucket devices employ hydraulic or electric drive opening and closing structures. Their working principle typically involves a hydraulic cylinder or electric actuator rotating the grab bucket arm around a hinge point, thus opening and closing the grab bucket. When the grab bucket moves to the distillery waste storage area, the drive mechanism opens the grab bucket and inserts it into the waste pile. The grab bucket then closes to grab the waste, and finally, a crane or other hoisting equipment transports the full grab bucket to a designated location for unloading.

[0004] In the existing technology, some devices with a single drive mode are difficult to adapt to the working conditions of distiller's grains with different humidity and density. When grabbing loose or compacted distiller's grains, the opening and closing speed of the grab bucket is slow and the grabbing force is insufficient, resulting in a long grabbing time, reducing work efficiency and restricting the continuity and efficiency of brewing production. In order to address the above problems, a distiller's grains grab bucket device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lees grabber device, which aims to improve the problem of low grabbing efficiency in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A grains grabber device includes a support block, a hook connected to the outer height of the support block, a connecting block fixedly connected to the bottom of the support block, a cleaning mechanism provided on the outside of the connecting block, a grabbing mechanism provided at the bottom of the connecting block, a grabbing protection mechanism provided on the grabbing mechanism, and a second cylinder fixedly connected to the outside of the connecting block. A connecting ring is fixedly connected to the driving end of the second cylinder, and a hollow push rod is rotatably connected to both sides of the connecting ring. A rotating column is fixedly connected to both sides of the hollow push rod, and two rotating connecting plates are rotatably connected to the outside of the rotating column. The rotating connecting plates are rotatably connected to the inside of the grabbing protection mechanism, and a linkage component is provided inside the grabbing protection mechanism.

[0011] The linkage component includes a connecting plate, which is externally fixedly connected to the inside of the grab bucket protection mechanism, and a rotating connecting rod is rotatably connected to the inside of the connecting plate.

[0012] As a further description of the above technical solution:

[0013] A rotating ring two is fixedly connected to the outside of the rotating connecting rod, and a support shaft is rotatably connected to the outside of the rotating ring two. The support shaft is fixedly connected to the inside of the support block.

[0014] As a further description of the above technical solution:

[0015] A support ring is fixedly connected to the outside of the support frame, and the support ring is fixedly connected to the outside of the motor. A rotating plate is fixedly connected to the drive end of the motor, and a connecting column is fixedly connected to the outside of the rotating plate.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the coordinated design of cylinder two and linkage components enables precise opening and closing and stable gripping of the grab bucket. The linkage transmission structure driven by cylinder two ensures that the grab bucket opens and closes quickly and flexibly, adapting to gripping needs under different working conditions. The rotating linkage in the linkage component cooperates with the support shaft to effectively disperse stress during the gripping process, improve the structural stability of the grab bucket, and reduce the risk of shaking and deformation. At the same time, the multi-layer protection of the grab bucket protection mechanism can resist corrosion and wear of the lees, extend the service life of the equipment, and significantly improve the efficiency and reliability of lees gripping operations.

[0024] 2. In this utility model, the linkage between cylinder one and motor achieves a highly efficient and intelligent cleaning function. Cylinder one controls the lifting and lowering of the cleaning block, ensuring that the cleaning block can quickly approach and move away from the grab bucket surface, avoiding interference with normal grabbing operations. The motor-driven rotating structure enables the cleaning block to clean the grab bucket surface without dead angles, which greatly improves efficiency compared to traditional manual cleaning, effectively reduces the residue of lees, and prevents problems such as grab bucket opening and closing jamming and accelerated corrosion caused by material adhesion. This not only ensures the continuous and stable operation of the equipment, but also reduces maintenance costs and manpower input. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a lees grab bucket device, including a support block 1. The support block 1 is used to bear the overall weight of the grab bucket and the load after grabbing the lees. It is connected to the hook 7 to achieve a stable connection with the hoisting equipment, ensuring the stability of the grab bucket during hoisting. The hook 7 is connected to the outer height of the support block 1. The hook 7 is made of high-strength alloy steel and has excellent load-bearing capacity and fatigue resistance. The bottom of the support block 1 is fixedly connected to a connecting block 2. The connecting block 2 connects the support block 1 to the cleaning mechanism 4 and the grabbing mechanism 6 below, transmits the load from the support block 1, and provides an installation foundation for the cleaning mechanism 4 and the grabbing mechanism 6. The cleaning mechanism 4 is set on the outside of the connecting block 2. The cleaning mechanism 4 is used to automatically remove the lees residue on the surface of the grab bucket, avoid material accumulation affecting the opening and closing efficiency and service life of the grab bucket, and reduce the frequency and cost of manual cleaning. The bottom of the connecting block 2 is set with a grabbing mechanism 6. The grabbing mechanism 6 realizes the opening and closing action of the grab bucket through precise mechanical transmission, and completes the grabbing and unloading operation of the lees. The grabbing mechanism 6 is equipped with a grab bucket protection mechanism 5.

[0034] The gripping mechanism 6 includes a second cylinder 61, which is a high-pressure, high-thrust double-acting cylinder. Through precise air pressure control, it achieves rapid and stable opening and closing of the grab. The second cylinder 61 is externally fixedly connected to the outside of the connecting block 2. A connecting ring 62 is fixedly connected to the drive end of the second cylinder 61. The connecting ring 62 converts the linear motion of the cylinder into the swinging motion of the hollow rod 63, ensuring effective power transmission and distribution. The hollow rod 63 is rotatably connected to both sides of the connecting ring 62. The hollow rod 63, through the lever principle, converts the linear displacement of the connecting ring 62 into the rotational motion of the rotating connecting plate 65, thereby opening and closing the grab. Rotating columns 64 are fixedly connected to the outer sides of the core rod 63. The rotating columns 64 are equipped with high-precision bearings to reduce frictional resistance, improve transmission efficiency, and ensure the smooth opening and closing of the grab bucket. Two rotating connecting plates 65 are rotatably connected to the outside of the rotating columns 64. The rotating connecting plates 65 directly drive the grab bucket protection mechanism 5 to open and close. The external rotating connecting plates 65 are rotatably connected to the inside of the grab bucket protection mechanism 5. The inside of the grab bucket protection mechanism 5 is equipped with a linkage component 66. During the opening and closing of the grab bucket, the linkage component 66 balances the force on each part of the grab bucket through its own linkage action, preventing structural deformation or shaking caused by uneven force, and improving the stability of the grab bucket operation.

[0035] The linkage component 66 includes a connecting plate 661, which is fixed inside the grab bucket protection mechanism 5 and provides installation support for components such as the rotating link 662. The external of the connecting plate 661 is fixedly connected to the inside of the grab bucket protection mechanism 5. The rotating link 662 is rotatably connected inside the connecting plate 661. When the grab bucket opens and closes, the rotating link 662 adjusts the force distribution of each part of the grab bucket by its own rotation, absorbing and dispersing the impact force generated during the grabbing process and avoiding local stress concentration. The external of the rotating link 662 is fixedly connected to a rotating ring 663, which cooperates with the support shaft 3 to provide a rotation fulcrum for the rotating link 662, ensuring its rotational flexibility and stability, while limiting the movement trajectory of the rotating link 662 and ensuring the linkage effect. The external of the rotating ring 663 is rotatably connected to the support shaft 3, which is fixed inside the support block 1, bearing and transmitting the force of the rotating link 662, and enhancing the overall structural strength of the grab bucket. The external of the support shaft 3 is fixedly connected to the inside of the support block 1.

[0036] Reference Figures 1 to 3The cleaning mechanism 4 includes a cylinder 41, which provides linear motion power to the cleaning mechanism 4. Through its extension and retraction, it controls the lifting and lowering of the cleaning block 49, enabling it to accurately approach or move away from the grab bucket surface, thus realizing the start and stop control of the cleaning operation. The cylinder 41 is externally fixedly connected to the outside of the connecting block 2. The drive end of the cylinder 41 is fixedly connected to a support frame 42. The support frame 42 is used to install components such as the motor 43 and the support ring 44, providing a stable support structure for the entire cleaning mechanism 4. The motor 43 is externally fixedly connected to the support frame 42, which enables the cleaning block 49 to rotate at the optimal speed, thereby improving cleaning efficiency.

[0037] A support ring 44 is fixedly connected to the outside of the support frame 42. The support ring 44 provides auxiliary support and positioning for the motor 43, enhancing the stability of the motor 43 installation. The support ring 44 is fixedly connected to the outside of the motor 43. A rotating plate 45 is fixedly connected to the drive end of the motor 43. The rotating plate 45 transmits the rotational power of the motor 43 to the connecting column 46. Through its own rotation, it drives the connecting column 46, rotating ring 47, and other components to rotate synchronously, realizing the circumferential motion of the cleaning block 49. The rotating plate 45 is fixedly connected to the outside of the connecting column 46, which transmits rotational power. A rotating ring 47 is fixedly connected to the outside of the connecting column 46. 7 cooperates with the rotating rod 48 to convert the rotational motion of the connecting column 46 into the swing of the rotating rod 48, which in turn drives the cleaning block 49 to rotate and clean around the surface of the grab bucket. The rotating rod 48 is rotatably connected to the outside of the rotating ring 47. The rotating rod 48 drives the cleaning block 49 to adhere to the surface of the grab bucket for all-round cleaning through its own swing. The outside of the rotating rod 48 is rotatably connected to the inside of the support frame 42. The cleaning block 49 is fixedly connected to the outside of the rotating rod 48. The cleaning block 49 is used to directly contact the surface of the grab bucket. It is made of highly elastic and wear-resistant rubber or special fiber material, which can effectively remove the residual lees on the surface of the grab bucket, while avoiding scratching the protective layer of the grab bucket surface.

[0038] The grab bucket protection mechanism 5 includes an anti-rust layer 51, which is made of a special anti-rust coating or stainless steel. It isolates air and moisture, preventing the metal surface of the grab bucket from rusting and corrosion. It is especially suitable for working conditions in the humid and acidic environment of the distillery, where rust is easily caused by acidic substances. The anti-rust layer 51 is externally fixedly connected to the outside of the rotating connecting plate 65. The anti-rust layer 51 is externally fixedly connected to a buffer layer 52, which is made of elastic rubber or polyurethane material. During the grab bucket grabbing, unloading and hoisting process, it absorbs external impact force and reduces the vibration and deformation of the grab bucket structure. The buffer layer 52 is externally fixedly connected to an anti-corrosion layer 53, which is made of acid and alkali resistant and corrosion resistant polymer material. It resists the chemical corrosion of the grab bucket by acidic and alkaline substances in the distillery, and extends the service life of the grab bucket. The anti-rust layer 51 is externally fixedly connected to the outside of the linkage component 66.

[0039] Working Principle: The hoisting equipment moves the grab bucket device above the storage area of ​​the lees using hook 7. After positioning, cylinder 61 pushes the connecting ring 62 downward. The connecting ring 62 drives the hollow push rods 63 on both sides to move downward synchronously. Since the hollow push rods 63 are rotatably connected to the rotating connecting plate 65 through the rotating column 64, the downward movement of the hollow push rods 63 causes the rotating connecting plate 65 to rotate around the rotating column 64, thereby causing the grab bucket protection mechanism 5 to open outward. When the grab bucket opens to a suitable angle, the hoisting equipment lowers the grab bucket, inserting it into the lees pile. Subsequently, cylinder 61 drives in the reverse direction, the connecting ring 62 moves upward, pulling the hollow push rod 63 to drive the rotating connecting plate 65 to rotate, causing the grab bucket protection mechanism 5 to close inward, clamping and grabbing the lees. During the grabbing process, the linkage component 66 plays a role. The rotating connecting rod 662, through the cooperation of the rotating ring 663 and the support shaft 3, maintains the stability of the overall structure of the grab bucket when the rotating connecting plate 65 moves, ensuring the smooth execution of the grabbing action.

[0040] After the grab bucket successfully grabs the distiller's grains, the hoisting equipment lifts the grab bucket and moves it above the designated unloading position. During the transfer process, the anti-rust layer 51, buffer layer 52, and anti-corrosion layer 53 in the grab bucket protection mechanism 5 come into play. The anti-rust layer 51 prevents the grab bucket from rusting due to external environmental factors, the buffer layer 52 reduces the impact force caused by shaking or collision during movement, and the anti-corrosion layer 53 resists corrosive substances such as distiller's grains, protecting the grab bucket structure and extending its service life.

[0041] After the grab bucket completes one or more grabbing and unloading operations, it needs to be cleaned to prevent residue from affecting subsequent operations. At this time, cylinder 41 pushes the support frame 42 downwards, bringing the cleaning block 49 closer to the grab bucket surface. Motor 43 drives the rotating plate 45 to rotate, which in turn drives the rotating ring 47 to rotate via connecting column 46. The rotating ring 47 cooperates with the rotating rod 48, causing the rotating rod 48 to rotate within the support frame 42. This causes the cleaning block 49 to rotate around the grab bucket surface, thoroughly cleaning the grab bucket and removing any remaining residue. After cleaning, cylinder 41 drives the support frame 42 upwards, resetting the cleaning block 49 to its original position, awaiting the next cleaning command.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
