Description

Technical Field

[0001] The utility model relates to the technical field of excavator attachments, and particularly relates to a five-petal standing lotus grab. Background Art

[0002] A lotus grab is a grasping tool used in conjunction with an excavator. Generally, it includes multiple claw-shaped parts that resemble a lotus and cooperate with each other. Each claw is driven by a hydraulic cylinder. The power source of the excavator transmits power to each hydraulic cylinder through a diverter, thereby realizing the opening and closing action of the claws.

[0003] However, currently, when the lotus grabs on the market are closed, their bottoms are oval-shaped, that is, egg-shaped. Such lotus grabs are not easy to place when idle and cannot maintain a standing state. Moreover, when they need to be used, since the lotus grabs are placed obliquely, the difficulty of matching with the excavator is relatively high, and the lotus grabs that cannot maintain a standing state are not convenient for either placement or mating connection.

[0004] The authorized utility model patent with the publication (announcement) number CN219604434U and the publication (announcement) date of August 29, 2023, discloses a five-petal lotus grab, which includes an upper connection plate, a lower connection plate, and a support column. The upper connection plate is connected to the lower connection plate through the support column. An oil supply part is arranged between the upper connection plate and the lower connection plate. Five hydraulic cylinders are rotatably connected to the upper connection plate, and five grab teeth are rotatably connected to the lower connection plate. The grab teeth are rotatably connected to the end of the piston rod of the hydraulic cylinder. It can complete the grasping action well, but it can be seen that the overall shape of this lotus grab is also slender. When closed, its bottom is egg-shaped and cannot be placed standing. It has little impact during use, but when idle, it cannot be placed vertically neatly, and the difficulty of docking is high and it takes a lot of time, which is not convenient.

[0005] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, in the spirit of seeking excellence and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, a five-petal standing lotus grab is provided specifically to solve the problems that the current lotus grab cannot be placed standing when closed, and the difficulty of mating connection is high and it takes a lot of time.

[0006] In addition, for the new patent with the publication (announcement) number CN219604434U, the structure of its lower connection plate is composed of two layers of connection plates sandwiching a plum blossom-shaped connecting piece in the middle. Refer to Figure 3 of this document to see that the plum blossom-shaped connecting piece of this structure needs to be connected to both the upper and lower connection plates. Not only is the structure relatively complex, but also the connection strength of multiple connections and the overall structural strength need to be improved, and the service life will be affected to a certain extent. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide a five-petal standable lotus grab, which is used to solve the problems that the existing lotus grab cannot stand and be placed when closed, and it is difficult and time-consuming to cooperate and dock.

[0008] The technical solution of the present utility model is realized as follows:

[0009] The five-petal standable lotus grab includes a first connection disk, a second connection disk, a support connecting piece and a claw. There are five support connecting pieces. The top and bottom of the support connecting piece are respectively connected to the first connection disk and the second connection disk. The support piece is sequentially provided with a first connection hole and a second connection hole from top to bottom. The second connection hole is rotationally connected to the connection part at the root of the claw by a second connection shaft. The claw includes an intermediate area. The first connection hole is rotationally connected to the driving cylinder by a first connection shaft. The cylinder body of the driving cylinder penetrates through the hollow area and the other end of the driving cylinder is rotationally connected to the inner side of the claw;

[0010] The claw includes a claw beam and a claw surface located inside the claw beam. The claw surface includes an arc-shaped outer end face and a flat bottom end face. The arc-shaped outer end face and the flat bottom end face are connected. The end of the flat bottom end face is provided with a flat head. The flat bottom end face and the flat head are on the same horizontal plane. In the closed state of the claw, each flat bottom end face and flat head are spliced into a plane.

[0011] As a preferred implementation manner, five first installation protrusions are uniformly arranged along the periphery of the first connection disk. Five claw placement openings are arranged on the second connection disk, and each claw placement opening is respectively arranged at the bottom side of the corresponding position of the five first installation protrusions;

[0012] One support connecting piece is installed at the bottom side of each of the five first installation protrusions, and each claw placement opening is used to provide a moving space for the corresponding claw.

[0013] As a preferred implementation manner, second installation protrusions are respectively arranged on the left and right sides of the claw placement opening. The two end feet at the bottom of the support connecting piece are respectively arranged on the second installation protrusions on both sides of the corresponding claw placement opening.

[0014] As a preferred implementation manner, adjacent claws cooperate with each other, and adjacent flat heads cooperate with each other. In the closed state of the claws, each claw surface is spliced into an inner grasping surface and each flat head is spliced into a pentagonal plane.

[0015] As a preferred implementation manner, the top and bottom of the support connecting piece are provided with parallel strip-shaped connecting end feet, and the support connecting piece is connected to the first connection disk and the second connection disk by the connecting end feet at the top and bottom.

[0016] The beneficial effects of the present utility model are:

[0017] When the present lotus grab is in the closed state, its bottom is flat, enabling it to be placed vertically. When not in use, it can be neatly placed vertically, occupying less space. Moreover, during use, it can be more quickly and conveniently coordinated and docked with an excavator, saving time and solving the problems that the current lotus grab cannot stand upright when closed and has high difficulty and consumes more time during coordination and docking.

[0018] In the prior art, the structure rotatably connected to the middle of the claw is the lower connecting plate. The specific structure of the lower connecting plate is that two upper and lower connecting plates sandwich a middle plum-blossom-shaped connecting piece, which is composed of a three-layer structure. However, in this solution, the structure rotatably connected to the middle of the claw is an integrated support connecting piece, and only the second connecting plate needs to be added at the bottom. The structure is simpler, not only facilitating processing, but also having higher structural strength, being more durable, and having a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS
