Description

Technical Field

[0001] The utility model relates to the technical field of loader equipment, in particular to a multifunctional bucket. Background Art

[0002] In engineering machinery equipment, the bucket, as the main working component of a loader, the design of its structure and function is directly related to the working efficiency and application range of the equipment. The traditional bucket design is often relatively single, and its main function is to shovel and transport bulk materials, which limits its application ability in diverse working conditions.

[0003] Chinese invention patent CN104264728B discloses a multifunctional bucket. Through innovative structural design, this bucket realizes the switching of multiple working modes to adapt to different operation requirements. This bucket includes a pusher, two jaw plates, a scraper and other main components. The two jaw plates are respectively located at both ends of the pusher, perpendicular to the pusher, and are hinged to the pusher through jaw plate pins. The setting of the jaw plate rotating oil cylinder enables the jaw plates to rotate around the jaw plate pins, increasing the flexibility of the bucket. The scraper is located between the two jaw plates, and its upper parts at both ends are hinged to the jaw plates through scraper pins. The scraper rotating oil cylinder enables the scraper to rotate around the scraper pins, further expanding the functions of the bucket.

[0004] When the jaw plates bite with both ends of the pusher and the lower edge of the scraper is close to the lower edge of the pusher, the pusher, the jaw plates and the scraper jointly form a bucket-shaped container with an upper opening. This can not only realize the traditional function of shoveling bulk materials, but also carry out the stacking and pushing operation of a large amount of materials. In addition, the biting design between the jaw plates and the pusher enables the bucket to have the function of a clamp and fork, and the design of the scraper can be used for the functions of spreading and turning over materials.

[0005] Although the patent of CN104264728B provides a multifunctional bucket, in actual application, there is still the possibility of further improving the working efficiency and adapting to more working conditions. For example, the existing design may be insufficient in adaptability in some specific working environments, or there is still room for improvement in terms of operation convenience and maintenance simplicity.

[0036] A multi-functional bucket, as Figures 1-4 shown, includes

[0037] an upper bucket 1, the upper bucket 1 includes a bottom plate 3 and side wall plates 4 connected to both sides of the bottom plate 3;

[0038] Lower bucket 2, the lower bucket 2 includes a side plate assembly 6 and a plurality of lower fork teeth 5, the lower fork teeth 5 are located at the front end of the lower bucket 2 and are arranged at intervals, and the lower bucket 2 is hinged to the upper bucket 1;

[0039] Opening and closing oil cylinder 7, both ends of the opening and closing oil cylinder 7 are respectively connected to the upper bucket 1 and the lower bucket 2, and the upper bucket 1 rotates under the action of the opening and closing oil cylinder 7 and abuts against the lower bucket 2 to form a bucket cavity 8.

[0040] Working principle: When the upper bucket 1 abuts against the lower bucket 2 under the action of the opening and closing oil cylinder 7 to form a bucket cavity 8, at this time, the compensation baffle 33 is equivalent to the side plate of the bucket cavity 8, and the entire bucket cavity 8 can realize the function of shoveling bulk materials such as stones and sand by a conventional loader; when the upper bucket 1 opens under the action of the opening and closing oil cylinder 7, items such as wood and bales of hay can be grabbed through cooperation with the upper bucket 1. At this time, the compensation baffle 33 rotates under the action of the wood or bales of hay, and the sawtooth on the side wall plate 4 directly contacts the wood or bales of hay, increasing the stability of the grab; when the upper bucket 1 is removed, the lower bucket 2 equipped with the lower fork teeth 5 forms a forklift, and the goods can be forked and loaded. Through the cooperation of the upper bucket 1 and the lower bucket 2, this solution can achieve multi-purpose use of one machine and meet the diversified working condition requirements.

[0041] In another preferred embodiment, the number of the opening and closing oil cylinders 7 is two groups. The side plate assembly 6 is provided with a side plate 9. The front part of the side plate 9 is provided with a connecting cross beam 11. The back of the side plate 9 is provided with a reinforcing cross beam 12, a hinge seat 13 connected to the opening and closing oil cylinder 7, and a support 14 connected to the loader. Each side end of the side plate 9 is provided with a group of boom plates 10. The upper end of each group of boom plates 10 is provided with a first hinge shaft 15 connected to the side wall plate 4, and the lower fork teeth 5 are connected to the connecting cross beam 11. By arranging the reinforcing cross beam 12 on the back of the side plate 9, the structural stability of the entire bucket can be significantly improved, especially during heavy-duty operations. The design of the connecting cross beam 11 at the front of the side plate 9 and the boom plates 10 at both side ends provides additional support points for the bucket, which helps to disperse the load and improve the load-bearing capacity of the bucket. The design of the two groups of opening and closing oil cylinders 7 allows for more precise and flexible control of the opening and closing actions of the bucket, thereby improving the operation efficiency and accuracy. The design of the hinge seat 13 and the support 14 simplifies the connection and fixation of the bucket to the loader, facilitating maintenance and operation. The design of connecting the lower fork teeth 5 to the connecting cross beam 11 enables the bucket to be used not only for traditional loading operations but also for forking operations, increasing the versatility of the equipment. The design of the reinforcing cross beam 12 and the connecting cross beam 11 helps to improve the overall durability of the bucket and extend the service life of the equipment.

[0042] In another preferred embodiment, the lower fork teeth 5 are provided with a first flange plate 16 connected to the connecting cross beam 11. One end of the first flange plate 16 is provided with a first convex shaft 17, and the other end is provided with a tooth portion 18. The connecting cross beam 11 is provided with a first bearing socket 19 that cooperates with the first convex shaft 17. The design of the first flange plate 16 increases the contact area between the lower fork teeth 5 and the connecting cross beam 11, thereby enhancing the connection stability between the two. The cooperative design of the first convex shaft 17 and the first bearing socket 19 simplifies the installation and maintenance process of the lower fork teeth 5, making disassembly and replacement more convenient and rapid. The tooth portion 18 of the first flange plate 16 provides additional support, enhancing the structural strength of the lower fork teeth 5 so that they can withstand greater loads. The cooperation mode of the first convex shaft 17 and the first bearing socket 19 helps to more effectively transmit mechanical loads, reduce stress concentration, and extend the service life of the components. This connection method can ensure the precise positioning of the lower fork teeth 5 during operation, improving the accuracy and efficiency of the operation. The cooperative design of the first convex shaft 17 and the first bearing socket 19 can reduce wear during operation and improve the durability of the components. If it is necessary to adjust the position of the lower fork teeth 5 or replace worn components, the design of the first convex shaft 17 and the first bearing socket 19 makes this process simpler. This design enables the lower fork teeth 5 to more easily adapt to different operating conditions and material types, improving the versatility of the bucket. By enhancing the connection stability and structural strength, this design helps to improve the safety during operation and reduce the risk of accidents caused by connection failure.

[0043] In another preferred embodiment, the tooth portion 18 includes a tooth front end 20, a tooth middle end 21, and a tooth rear end 22. The upper surfaces of the tooth front end 20, the tooth middle end 21, and the tooth rear end 22 are all provided with an inclination angle, and a stop block 23 is provided at the connection position between the tooth front end 20 and the tooth middle end 21. The inclination angle design of the upper surfaces of the tooth front end 20, the tooth middle end 21, and the tooth rear end 22 helps to reduce the resistance of the material inside the bucket, making it easier for the material to be loaded and moved. The inclination angle design makes the unloading of the material smoother, reduces the situation of the material adhering to the inner wall of the bucket, and improves the unloading efficiency. The setting of the stop block 23 helps to protect the front edge of the bucket, reduces the wear of the front part of the bucket by the material during the shoveling process, and extends the service life of the bucket. The addition of the stop block 23 enhances the structural strength of the tooth portion 18, enabling it to withstand greater loads and impacts. The inclination angle design helps to guide the material to flow towards the center of the bucket, reduces the overflow and scattering of the material during the loading process, and improves the loading efficiency. The setting of different inclination angles enables the bucket to adapt to different types of materials and operating conditions, improving the flexibility and adaptability of the operation. By reducing the resistance and overflow of the material inside the bucket, the potential risks during the operation are reduced, improving the safety of the operation.

[0044] In another preferred embodiment, the bottom plate 3 includes a front material shoveling part 24 and a rear material shoveling part 25.

The bottom of the bottom plate 3 is provided with multiple groups of cavity grooves for accommodating the lower fork teeth 5, which are composed of rib plates 26. A transition cavity groove 27 is provided at the position of the front material shoveling part 24 corresponding to the lower fork teeth 5. The inclination angle design of the upper end surfaces of the front material shoveling part 24 and the rear material shoveling part 25 helps to reduce the resistance of the material inside the bucket, making it easier for the material to be loaded and moved. The inclination angle design enables the material to be unloaded more smoothly, reducing the situation where the material adheres to the inner wall of the bucket and improving the unloading efficiency. The rib plate 26 design at the bottom of the bottom plate 3 enhances the structural strength of the bottom plate, enabling it to withstand greater loads and impacts. The design of the transition cavity groove 27 helps to guide the material to flow towards the center of the bucket, reducing the overflow and scattering of the material during the loading process and improving the loading efficiency. The setting of different inclination angles enables the bucket to adapt to different types of materials and operating conditions, improving the flexibility and adaptability of the operation. Due to the design of the rib plates 26 and the transition cavity groove 27 reducing wear, the maintenance cost of the bucket is reduced, improving the economy of the equipment. By reducing the resistance and overflow of the material inside the bucket, the potential risks during the operation process are reduced, improving the safety of the operation. The design of the cavity groove provides a stable installation position for the lower fork teeth 5, facilitating installation and maintenance. The rib plate 26 design helps to disperse stress and reduce local stress concentration, thereby improving the durability and service life of the bucket.

[0045] In another preferred embodiment, multiple groups of upper fork teeth 28 arranged at intervals are further provided at one end of the bottom plate 3 away from the front material shoveling part 24. The upper fork teeth 28 are detachably connected to the bottom plate 3. The design of the upper fork teeth 28 enables the bucket to adapt to more operation requirements, such as grasping wood, bale of forage, etc., increasing the versatility of the equipment. The detachable connection design between the upper fork teeth 28 and the bottom plate 3 enables the upper fork teeth to be quickly installed or disassembled when needed, facilitating the quick switching of the bucket function according to the operation requirements. The presence of the upper fork teeth 28 increases the single-grab volume, especially when dealing with materials with a larger volume, improving the operation efficiency. The upper fork teeth 28 and the lower fork teeth 5 of the lower bucket 2 form a clamping fork structure, increasing the stability when grasping the material and reducing the slippage of the material during the handling process. The detachable design enables the upper fork teeth 28 to be replaced individually when damaged or worn, without the need to replace the entire bottom plate 3, reducing the maintenance cost. The design and material selection of the upper fork teeth 28 can be optimized according to specific operation requirements, improving their durability and load-bearing capacity. The design of the upper fork teeth 28 enables the bucket to adapt to different materials and operating environments, such as use in specific occasions like a wood yard, a forage yard, etc. The detachable upper fork teeth 28 facilitate regular maintenance and inspection, promptly discovering and solving problems to ensure the normal operation of the equipment.

[0046] In another preferred embodiment, the upper fork teeth 28 are provided with a second flange plate 29 connected to the bottom plate 3. One end of the second flange plate 29 is provided with a second convex shaft 30. The end of the second convex shaft 30 is provided with a thread, and the other end is provided with an arc-shaped tooth 31. The bottom plate 3 is provided with a second bearing socket 32 that cooperates with the second convex shaft 30. The end of the second convex shaft passes through the second bearing socket and is fixed by a nut. The design of the second flange plate 29 enables the upper fork teeth 28 to be quickly and conveniently installed and disassembled, improving the efficiency of maintenance and replacement. The cooperation between the second convex shaft 30 and the second bearing socket 32, as well as the design of fixing by a nut, ensures the connection stability between the upper fork teeth 28 and the bottom plate 3, preventing loosening during operation. The thread design at the end of the second convex shaft 30 and the configuration of the arc-shaped tooth 31 increase the load-bearing coefficient of the upper fork teeth 28, enabling them to bear greater loads. The design of the arc-shaped tooth 31 helps to reduce the wear when the material contacts the upper fork teeth 28, extending the service life of the upper fork teeth. This design allows the upper fork teeth 28 to be adjusted according to different operation requirements, improving the adaptability and versatility of the bucket. The ability to be quickly installed and disassembled enables the operator to quickly adjust the bucket configuration according to different operation scenarios, thereby improving the operation efficiency. When the upper fork teeth 28 need to be maintained or replaced, due to their detachable design, it can be easily carried out, reducing the maintenance time and cost. The stable connection reduces the safety risks caused by unstable connection during operation, improving the operation safety. The detachable design makes it easier to regularly check the condition of the upper fork teeth 28, helping to detect and solve problems in a timely manner.

[0047] In another preferred embodiment, each set of the side wall plates 4 is provided with a set of complementary baffle plates 33. The complementary baffle plates 33 are connected to the side wall plates 4 by bolts 34 and can rotate around the bolts 34 under the action of an external force. The design of the complementary baffle plates 33 helps to provide additional support and fixation when grasping materials such as wood and baled hay, increasing the stability of grasping. Under the action of an external force, the complementary baffle plates 33 can rotate to adapt to materials of different shapes, reducing the slipping and scattering of materials during handling. The complementary baffle plates 33 can be adjusted according to the characteristics of different materials, improving the adaptability of the bucket to different materials. The complementary baffle plates 33 are connected to the side wall plates 4 by bolts 34. This design makes the baffle plates easy to disassemble and replace, facilitating maintenance and repair. The design of the complementary baffle plates 33 helps to disperse the impact force of the materials on the side wall plates 4, reducing the wear of the side wall plates and thus improving the durability of the entire bucket. The rotation function of the complementary baffle plates 33 makes the bucket more efficient when loading and unloading materials, reducing the operation time. The complementary baffle plates 33 help to keep the materials stable when grasping, reducing safety accidents caused by the movement or slipping of the materials. The complementary baffle plates 33 can be adjusted according to the operation requirements, enabling the bucket to adapt to more types of working environments and materials. The rotatable complementary baffle plates 33 facilitate the operator to check the condition of the baffle plates and promptly discover and solve problems.

[0048] In another preferred embodiment, each set of the side wall plates 4 is further provided with saw teeth for grasping goods. The design of the saw teeth increases the friction between the side wall plates 4 and the goods, improving the stability and safety during grasping. During handling, the saw teeth can effectively prevent the goods from slipping off the side wall plates 4, especially when handling materials with wet or smooth surfaces. The saw teeth help to quickly and firmly grasp the goods, reducing the number of re-grasping times and thus improving the operation efficiency. The design of the saw teeth enables the side wall plates 4 to adapt to goods of various shapes and sizes, increasing the versatility of the bucket. The saw teeth are usually made of wear-resistant materials, which helps to extend the service life of the side wall plates 4 and reduce the wear caused by frequent contact with the goods. If the saw teeth are worn or damaged, they can be relatively easily replaced or repaired to maintain the best working condition of the bucket. The presence of the saw teeth gives the operator more control during the grasping operation, improving the flexibility of the operation. Compared with sharp edges, the grasping method of the saw teeth can reduce damage to the surface of the goods, especially suitable for handling vulnerable goods. By reducing the movement and slipping of the goods during handling, the saw teeth help to reduce the safety risks during the operation.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
