Description

Technical Field

[0001] This utility model relates to the field of grab bucket technology, specifically a three-lobed grab bucket with an anti-slip structure. Background Technology

[0002] A three-lobed grab is a specialized tool for grabbing bulk cargo. It consists of three openable and closable bucket-shaped jaws. This design allows the three-lobed grab to form a relatively tight structure when closed, effectively preventing cargo spillage. However, in the use of existing three-lobed grabs, the jaw structure is simple. For some bulk cargo with a low coefficient of friction, it is easy to slip through the gaps between the jaws during transfer and grabbing, affecting the grabbing volume and grabbing efficiency. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a three-lobed grab bucket with an anti-slip structure. Through the cooperation of the three-lobed grab bucket component and the anti-slip component, a disassembled structure is formed inside the bucket plate during use, which makes it easy to directly add the anti-slip structure. This allows for the free selection of increasing the friction coefficient of the bucket plate, thereby playing a role in gripping goods without slipping and preventing small materials from falling.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a three-lobed grab bucket with an anti-slip structure, comprising:

[0006] An anti-slip assembly includes an anti-slip inner plate that fits against the inner side of the bucket plate, a threaded post fixed to the outer wall of the anti-slip inner plate, a through hole opened on the surface of the bucket plate, and a threaded ring disposed on the outer side of the bucket plate.

[0007] As a preferred embodiment of the three-lobed grab bucket with anti-slip structure described in this utility model, the main arm is rotatably connected to the flange, and the back ribs and the main arm are respectively distributed on both sides of the bucket plate.

[0008] As a preferred embodiment of the three-lobed grab bucket with anti-slip structure described in this utility model, two threaded posts are provided, and the two threaded posts are symmetrically arranged at the center line position of the anti-slip inner plate.

[0009] As a preferred embodiment of the three-lobed grab bucket with anti-slip structure described in this utility model, the anti-slip component further includes a long slot formed on the surface of the bucket plate and a strong magnet disposed in the long slot.

[0010] As a preferred embodiment of the three-lobed grab bucket with anti-slip structure described in this utility model, it further includes a locking assembly, which includes a first notch groove formed in the opening on the surface of the bucket plate and a second notch groove formed in the opening on the surface of the anti-slip inner plate.

[0011] As a preferred embodiment of the three-lobed grab bucket with anti-slip structure described in this utility model, the locking assembly further includes a rotating shaft disposed in the second notch groove, an L-shaped metal hook connected to the rotating shaft, and a metal cross plate connected to the rotating shaft.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides a three-lobed grab bucket with an anti-slip structure. Through the cooperation of the three-lobed grab bucket component and the anti-slip component, a disassembled structure is formed inside the bucket plate during use, which makes it easy to directly add the anti-slip structure. This allows for the free selection of increasing the friction coefficient of the bucket plate, thereby playing a role in gripping goods without slipping and preventing small materials from slipping.

[0026] Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shown is an overall structural schematic of one embodiment of a three-lobed grab bucket with an anti-slip structure according to this utility model. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The main structure of this embodiment includes: a three-lobed grab bucket assembly and an anti-slip assembly;

[0027] The three-lobed grab bucket assembly is used to gather and grab goods. Specifically, the three-lobed grab bucket assembly includes a hydraulic cylinder 11, a piston rod 12 connected to the output end of the hydraulic cylinder 11, a concave frame 13 connected to the housing of the hydraulic cylinder 11, a flange 14 connected to the piston rod 12, a connecting rod 15 movably connected to the concave frame 13, a back rib 16 movably connected to the connecting rod 15, a bucket plate 17 movably connected to the back rib 16, and a main arm 18 connected to the inner side of the bucket plate 17.

[0028] In actual use, the hydraulic cylinder 11 drives the piston rod 12 to move. During the movement of the piston rod 12, the flange 14 is pushed forward. The flange 14 directly drives the main arm 18 to move. Since the back rib 16 is movably connected to the connecting rod 15, the distributed bucket plates 17 can unfold outward. Thus, when the piston rod 12 moves upward, it can be gathered to grab the goods.

[0029] The anti-slip component is used to increase the coefficient of friction and improve gripping stability. Specifically, the anti-slip component includes an anti-slip inner plate 21 that is attached to the inner side of the bucket plate 17, a threaded post 22 that is fixed to the outer wall of the anti-slip inner plate 21, a through hole 24 that is opened on the surface of the bucket plate 17, and a threaded ring 23 that is provided on the outer side of the bucket plate 17. The anti-slip component also includes a long slot 25 that is opened on the surface of the bucket plate 17 and a strong magnet 26 that is provided in the long slot 25.

[0030] In practical use, the threaded post 22 passes through the through hole 24 and is threadedly connected to the threaded post 22 using a threaded ring 23, thereby locking the anti-slip inner plate 21 to the inside of the bucket plate 17. The anti-slip inner plate 21 provides anti-slip treatment to the inside of the bucket plate 17. During use, the strong magnet 26 embedded in the long slot 25 attracts the outer wall of the anti-slip inner plate 21 to prevent shaking during use and improve the stability of use.

[0031] Furthermore, the locking components ensure that the anti-slip plate automatically locks and tightens during installation, ensuring the stability of the anti-slip plate after installation and preventing it from shaking or coming off during use.

[0032] Specifically, it also includes a locking assembly, which includes a first notch 31 opened in the opening on the surface of the bucket plate 17, a second notch 32 opened in the opening on the surface of the anti-slip inner plate 21, and a pivot 33 disposed in the second notch 32, an L-shaped metal hook 34 connected to the pivot 33, and a metal cross plate 35 connected to the pivot 33.

[0033] In actual use, during the process of the bucket plate 17 and the anti-slip inner plate 21 being attached, the inner wall of the bucket plate 17 will directly press on the metal horizontal plate 35. At this time, the metal horizontal plate 35 will drive the L-shaped metal hook 34 to rotate until the L-shaped metal hook 34 and the first notch 31 are hooked and locked together. In this way, the threaded column 22 completes the secondary locking, ensuring the stability of the bucket plate 17 after anti-slip is used.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
