Description

Technical Field

[0001] This invention relates to the field of bucket technology, specifically to a multi-functional bucket for a loader. Background Technology

[0002] A loader bucket is an engineering machinery device used for loading, transporting, and unloading various materials. It is typically mounted at the front of the loader and its movement is controlled by a hydraulic system. The loader bucket consists of bucket teeth, bucket housing, bucket arm, and hydraulic cylinders. Because traditional buckets have a single function, they lack protection at the top when loading or transporting low-density, easily floating objects (such as foam in construction waste). Therefore, existing buckets generally have intercepting grilles at the top to prevent objects from spilling out, thus intercepting and protecting the contents of the bucket. However, existing buckets only have loading and protection functions, making them relatively simple. When it comes to moving items on pallets (such as curbs placed on pallets in road construction), it becomes difficult. Therefore, the existing loader buckets have a limited function and narrow application range.

[0003] For example, patent CN205314150U discloses a multi-functional bucket for a loader. The bucket body has a rotating baffle on top, and protective plates on both sides to prevent material leakage. These protective plates consist of a fixed plate and a folding plate. The fixed plate is welded to the outer wall of the bucket body, and the folding plate is hinged to the fixed plate via a pivot. A cylinder is located at the rear of the bucket body, with its extension end connected to the rear end of the rotating baffle. A support plate is located below the cylinder at the rear of the bucket body, and the cylinder is fixed to the support plate. The rotating baffle consists of a straight plate and an arc-shaped plate. A fixed seat with through holes is located at each end of the upper part of the bucket body, and pins are located on both sides of the straight plate corresponding to the fixed seats. Several shovel teeth are evenly distributed on the lower edge of the bucket body, and these teeth are movably connected to the bucket body. This bucket, equipped with a rotating baffle and folding side baffles, prevents material leakage from the front and sides during operation, maximizing the bucket's working volume.

[0004] Although the bucket in the aforementioned patent can prevent material from spilling from the front and sides during operation, existing buckets cannot move pallets or objects on them (such as curbs placed on pallets in road construction). To move pallets and objects on them, a forklift must be used. Therefore, the existing buckets used in loaders have limited functionality and narrow applicability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-functional bucket for loaders, which solves the problems mentioned in the background art, enabling the bucket to have multiple functions, including loading and unloading goods, and temporarily serving as a forklift.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional bucket for a loader, comprising a bucket body, a protective frame connected to the top of the bucket body, a rotating shaft rotatably connected to the lower end of the protective frame, a side baffle connected to the outer wall of the rotating shaft, threaded bushings threaded to both ends of the rotating shaft, the threaded bushings being slidably connected to the protective frame, a motor box connected to the lower end of the protective frame, an electric motor connected inside the motor box, a drive gear connected to the output end of the electric motor, a transmission gear meshing on one side of the drive gear, the transmission gear being sleeved on the outer wall of one end of the rotating shaft, and the transmission gear being connected to the rotating shaft.

[0007] Furthermore, two sets of locking blocks are connected to the middle position of the outer wall of the rotating shaft. One side of each locking block is provided with a limiting ring connected to the rotating shaft. A central baffle is connected to the middle position of the outer wall of the rotating shaft. The end of the central baffle near the rotating shaft has a locking groove that matches the locking block. A horizontal plate is connected to the middle position of the protective frame. A cylinder is connected to the middle position of the horizontal plate. A limiting push block is connected to the output end of the cylinder. A protrusion is connected to the side of the limiting push block away from the horizontal plate. A limiting groove that matches the protrusion is provided on the side of the central baffle near the protrusion.

[0008] Furthermore, a positioning ring is connected to the end of the side wall of the limiting push block away from the protrusion, and the positioning ring is rotatably connected to the rotating shaft. A limiting plate is connected to the side of the horizontal plate away from the protrusion, and the limiting plate matches the central baffle.

[0009] Furthermore, side plates are connected to both sides of the central baffle.

[0010] Furthermore, the top and bottom of the side baffle are provided with cavities, an extension plate is slidably connected in the cavity, an elastic element is connected to one end of the extension plate near the cavity, the other end of the elastic element is connected to the inner wall of the cavity, and both ends of the horizontal plate are connected to ejection fixing components.

[0011] Furthermore, the ejector fixing assembly includes an extrusion block and an extrusion groove. A set of extrusion blocks are connected to both ends of the horizontal plate. An extrusion groove matching the extrusion block is opened in the middle of the extension plate. The top of the extrusion block is an inclined surface.

[0012] Furthermore, a plug rod is connected inside the cavity, and a slot matching the plug rod is provided inside the extension plate.

[0013] Furthermore, the outer wall of the threaded bushing is connected to a plurality of positioning blocks, which are equidistantly distributed.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of loader uses a multi-functional bucket. When the loader needs to move pallets and objects on the pallets (such as curbs placed on pallets during road construction) at the construction site, the protective frame can be lowered first, and then the motor can be started. The motor controls the side panels to be in a horizontal state, and then the side panels can be used as forks to move the pallets or objects placed on them. This improves the functionality of the loader bucket and gives the loader bucket multiple functions. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-10 A multi-functional bucket for a loader includes a bucket body 1, a protective frame 2 connected to the top of the bucket body 1, a rotating shaft 8 rotatably connected to the lower end of the protective frame 2, a side baffle 11 fixedly connected to the outer wall of the rotating shaft 8, threaded bushings 9 threadedly connected to both ends of the rotating shaft 8, the threaded bushings 9 being slidably connected to the protective frame 2, a motor box 4 connected to the lower end of the protective frame 2, an electric motor 5 connected inside the motor box 4, a drive gear 6 connected to the output end of the electric motor 5, a transmission gear 7 meshing on one side of the drive gear 6, the transmission gear 7 being sleeved on the outer wall of one end of the rotating shaft 8, and the transmission gear 7 being connected to the rotating shaft 8.

[0029] The multi-functional bucket of the loader in this invention allows for the following operation: When the loader needs to move a pallet and objects on it (such as curbs placed on the pallet during road construction) at a construction site, the protective frame 2 can be lowered so that it is inside the main body 1 of the bucket. Then, the motor 5 inside the motor box 4 is started, controlling the side baffle 11 to rotate to a horizontal position. The side baffle 11 can then be used as forks (such as...). Figure 2 As shown), this allows for the handling of pallets or objects placed on them, thereby improving the functionality of the loader bucket body 1. The loader bucket body 1 can not only load and unload goods but also protect the items inside, and can temporarily function as a forklift, thus expanding its applicability. Meanwhile, the motor 5 inside the motor box 4 is part of the loader, controlled and powered by it. Since the motor 5 is a product of existing mature technology, it is not described in detail here. Furthermore, the structure of the bucket body 1 and the protective frame 2 in this invention is similar to the multi-functional bucket structure for loaders disclosed in patent patent authorization announcement number CN205314150U, so it will not be elaborated upon here.

[0030] As a preferred embodiment of the present invention, two sets of locking blocks 20 are connected to the middle position of the outer wall of the rotating shaft 8. A limiting ring 21 connected to the rotating shaft 8 is provided on one side of the locking block 20. A central baffle 10 is connected to the middle position of the outer wall of the rotating shaft 8. A locking groove 19 matching the locking block 20 is opened at the end of the central baffle 10 near the rotating shaft 8. A horizontal plate 3 is connected to the middle position of the protective frame 2. A cylinder 22 is connected to the middle position of the horizontal plate 3. A limiting push block 23 is connected to the output end of the cylinder 22. A protrusion is connected to the side of the limiting push block 23 away from the horizontal plate 3. A limiting groove 25 matching the protrusion is opened on the side of the central baffle 10 near the protrusion.

[0031] Specifically, when the bucket body 1 needs to transport wide objects, before starting the motor 5 to rotate the side baffle 11 to a horizontal position, the cylinder 22 drives the limit push block 23 to move, thereby causing the center baffle 10 to move towards the locking block 20, so that the locking groove 19 at one end of the center baffle 10 is locked onto the locking block 20. Then, the motor 5 is started. At this time, when the motor 5 drives the rotating shaft 8 to rotate, the side baffle 11 and the center baffle 10 will rotate synchronously until they are rotated to a horizontal position, thus forming a horizontal placement platform, which is convenient for transporting wide objects (that is, the entire bucket body 1 is transformed from...). Figure 1 The state transition to Figure 3 (State); After the object is transported, start the motor 5 and flip it so that the center baffle 10 is tightly attached to the horizontal plate 3 again. After the center baffle 10 is tightly attached to the horizontal plate 3, the cylinder 22 can be started to move the limit push block 23 to its original position. At this time, the protrusion on the limit push block 23 will be inserted into the limit groove 25, thereby driving the center baffle 10 to move and restricting the center baffle 10 to prevent displacement. At the same time, the cylinder 22 is controlled and powered by the loader. Since the cylinder 22 is a mature technology, it will not be elaborated on here.

[0032] As a preferred technical solution of the present invention, a positioning ring 24 is connected to the end of the side wall of the limiting push block 23 away from the protrusion. The positioning ring 24 is rotatably connected to the rotating shaft 8. A limiting plate 301 is connected to the side of the horizontal plate 3 away from the protrusion. The limiting plate 301 matches the central baffle 10. When the cylinder 22 drives the limiting push block 23 to move, the positioning ring 24 will move synchronously. When the slot 19 at one end of the central baffle 10 is engaged with the block 20, the positioning ring 24 will be in close contact with one side of the central baffle 10, while the other side of the central baffle 10 will be in close contact with the limiting ring 21, thereby restricting the central baffle 10 and preventing it from moving laterally in a horizontal state, which would affect the transportation of the object. After the object is transported and the central baffle 10 is reset, the protrusion on the limiting push block 23 will be inserted into the limiting groove 25 on one side of the central baffle 10, while the other side of the central baffle 10 will be in close contact with the limiting plate 301, thereby improving the stability of the central baffle 10.

[0033] As a preferred embodiment of the present invention, side plates 26 are connected to both sides of the central baffle 10. The side plates 26 increase the area of ​​the central baffle 10, making the object more stable to be placed, and when used as the vertical bar of the protective frame 2, they can also improve the protective interception effect and prevent objects with low density from falling out of the bucket body 1.

[0034] As a preferred embodiment of the present invention, cavities 13 are provided at both the top and bottom of the side baffle 11. An extension plate 14 is slidably connected within the cavity 13. An elastic element 17 is connected to one end of the extension plate 14 near the cavity 13, and the other end of the elastic element 17 is connected to the inner wall of the cavity 13. Both ends of the horizontal plate 3 are connected to ejection fixing components. When the motor 5 drives the side baffle 11 to rotate towards the horizontal plate 3, the ejection fixing components will eject the extension plate 14, thereby expanding the interception area of ​​the side baffle 11 and improving the interception and protection effect. When the motor 5 drives the side baffle 11 to rotate away from the horizontal plate 3, the extension plate 14 will retract into the cavity 13 under the action of the elastic element 17, thereby reducing the area of ​​the side baffle 11 and facilitating its use as a fork.

[0035] As a preferred embodiment of the present invention, the ejector fixing assembly includes an extrusion block 12 and an extrusion groove 18. A set of extrusion blocks 12 are connected to each end of the horizontal plate 3. An extrusion groove 18 matching the extrusion block 12 is provided in the middle of the extension plate 14. The top of the extrusion block 12 is inclined. When the side baffle 11 approaches the horizontal plate 3, the extrusion block 12 inserts into the extrusion groove 18 in the middle of the extension plate 14. Because the top of the extrusion block 12 is inclined, the extension plate 14 is slowly pushed away from the side baffle 11 by the extrusion block 12.

[0036] As a preferred embodiment of the present invention, a plug rod 16 is connected inside the cavity 13, and a slot 15 matching the plug rod 16 is provided inside the extension plate 14. The plug rod 16 is located in the slot 15 of the extension plate 14, thereby preventing the extension plate 14 from tilting or getting stuck when it moves.

[0037] As a preferred embodiment of the present invention, the outer wall of the threaded bushing 9 is connected with a plurality of positioning blocks, which are evenly distributed. The positioning blocks restrict the threaded bushing 9, and when the rotating shaft 8 rotates, the threaded bushing 9 will move away from the rotating shaft 8, thereby inserting into the grooves on both sides of the bucket body 1, thereby restricting the protective frame 2 and preventing the protective frame 2 from shaking.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
