Description

Technical Field

[0001] This utility model belongs to the field of bucket technology, specifically relating to a bucket with a quick-change bucket clamp. Background Technology

[0002] An excavator bucket clamp is an accessory device installed on the excavator bucket, mainly used for grabbing, moving, and clamping various objects to expand the excavator's operational capabilities. It typically consists of a hydraulic drive system and a gripper mechanism. The hydraulic system provides power through the excavator's hydraulic oil circuit to control the opening and closing of the gripper.

[0003] Currently, welding is the mainstream method for connecting the bucket clamp and the telescopic boom. Welding, with its ability to create a strong metallurgical bond, greatly improves the stability and reliability of the connection, ensuring that the bucket clamp and telescopic boom remain tightly connected during high-intensity operations such as digging and grabbing, thus effectively guaranteeing the smooth progress of the operation.

[0004] However, this seemingly perfect connection method reveals significant drawbacks in equipment maintenance. Once the bucket clamp wears out or becomes damaged due to prolonged use, or if a different type of bucket clamp needs to be replaced to adapt to new tasks, disassembly becomes extremely difficult. Because the welded connection is extremely strong, conventional disassembly tools are ineffective, often requiring complex and time-consuming processes such as cutting and grinding. This not only greatly increases the workload of maintenance personnel, prolongs equipment downtime, and reduces production efficiency, but may also cause irreversible damage to the telescopic boom during disassembly, thereby affecting the overall performance and service life of the excavator and increasing subsequent maintenance costs. Utility Model Content

[0005] The purpose of this invention is to provide a bucket with a quickly replaceable bucket clip, aiming to solve the problem of difficult disassembly when the bucket clip wears out or is damaged due to long-term use, or when different types of bucket clips need to be replaced to adapt to new work tasks. Because the welded connection has extremely high strength, conventional disassembly tools are ineffective, often requiring complex and time-consuming processes such as cutting and grinding. This not only greatly increases the workload of maintenance personnel, prolongs equipment downtime, and reduces production efficiency, but may also cause irreversible damage to the telescopic boom during disassembly, thereby affecting the overall performance and service life of the excavator and increasing subsequent maintenance costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bucket with a quick-change bucket clamp, including a clamping jaw, a connecting rod installed between the two clamping parts of the clamping jaw, a docking post installed at one end of the two clamping parts of the clamping jaw, a connecting block welded to one side of the docking post, and the other side of the connecting block welded to the outer wall of the side plate.

[0007] Two side plates are symmetrically welded to the other side of the side plate, and a rotating block is provided between the two side plates. A fixed plate is welded to the other side of the rotating block. One side of the fixed plate is pre-welded to the telescopic arm of the excavator when in use. A bucket is connected to the bottom of the telescopic arm.

[0008] In order to enable the side plates to be mounted on the telescopic arm via the fixing plate, as the bucket of the present invention with quick-change bucket clamp, preferably, a round hole is opened through both the two side plates and the rotating block in the same horizontal direction, and a connecting rod is installed through the round hole of the two side plates and the rotating block.

[0009] The connecting rod has a recessed threaded hole at each end, and a tightening bolt is threaded into each threaded hole of the connecting rod. A ring of pressure posts is installed at equal intervals on one end of the tightening bolt.

[0010] A ring groove is formed on the outer edge of the circular hole on the side away from the two side plates. A gasket is embedded in the ring groove. After the tightening bolt is tightened, one end of the pressure column is pressed against the outer wall of the gasket.

[0011] To prevent the side plates from shifting left and right on the connecting rod as the grippers rotate, the bucket of this invention, which allows for quick-change bucket clamps, preferably has a ring of positioning posts installed at equal intervals on the outer edge of the circular holes on opposite sides of the two side plates. The end of the positioning post away from the side plate is a semi-circular structure, and the semi-circular end of the positioning post is in contact with the outer wall of the rotating block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When it is necessary to replace the gripper, remove one of the tightening bolts and then pull the other tightening bolt. When the tightening bolt is under tension, it will drive the connecting rod to move. Eventually, the connecting rod will disengage from the fixed block and the rotating block. Thus, the side plate can be separated from the fixed plate, and the gripper can be removed from the telescopic arm. This method is more convenient than the disassembly method after welding, and is more convenient for actual operation.

[0014] When installing the gripper, the rotating block is positioned between the two fixed blocks, and the rotating block will make movable contact with the positioning post on the outer wall of the fixed blocks. This achieves a positioning effect, aligning the through hole on the rotating block with the through hole on the fixed block. Next, the connecting rod is inserted into the through holes of the rotating block and the fixed blocks, and a tightening bolt is tightened on both sides of the fixed block. When the pressure post on one side of the tightening bolt presses against the outer wall of the gasket, the connection between the tightening bolt and the fixed block is secure. In this way, the gripper can complete the connection with the telescopic arm. In actual use, this connection method simplifies the gripper installation process and facilitates the installation operation for workers. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a bucket with a quick-change bucket clamp, including a clamp 1, a connecting rod 2 installed between the two clamps of the clamp 1, a docking post 3 installed at one end of the two clamps of the clamp 1, a connecting block 4 welded to one side of the docking post 3, and the other side of the connecting block 4 welded to the outer wall of the side plate 5.

[0024] Two side plates 5 are symmetrically welded on the other side of the side plate 5. A rotating block 7 is set between the two side plates 5. A fixed plate 8 is welded on the other side of the rotating block 7. When in use, one side of the fixed plate 8 is pre-welded to the telescopic boom 11 of the excavator. The bottom of the telescopic boom 11 is connected to the bucket 12.

[0025] During use, the fixing plate 8 is pre-welded to the telescopic boom 11 of the excavator. After welding, the fixing plate 8 will maintain a stable fixed docking structure with the telescopic boom 11. In the subsequent disassembly process, the welded fixing structure between the telescopic boom 11 and the fixing plate 8 will not be removed.

[0026] The connecting rod 2 on the gripper 1 is connected to the corresponding telescopic cylinder, and the other end of the telescopic cylinder is installed on the telescopic arm 11. In this way, the movement of the telescopic cylinder can drive the gripper 1 to complete the corresponding clamping operation.

[0027] Preferably, a circular hole is provided through both side plates 5 and the rotating block 7 in the same horizontal direction, and a connecting rod 61 is installed through the circular holes of the two side plates 5 and the rotating block 7.

[0028] Each end of the connecting rod 61 has a recessed threaded hole, and a tightening bolt 62 is threaded into each threaded hole of the connecting rod 61. A ring of pressure posts 63 is installed at equal intervals on one end of the tightening bolt 62.

[0029] A ring groove 64 is formed on the outer edge of the circular hole on one side of the two side plates 5. A gasket 65 is embedded inside the ring groove 64. After the tightening bolt 62 is tightened, one end of the pressure column 63 is pressed against the outer wall of the gasket 65.

[0030] In practical use, the gasket 65 is installed in the annular groove 64. When the tightening bolt 62 is tightened, the pressure post 63 at one end of the tightening bolt 62 will press against the outer wall of the gasket 65. At this time, the operator can clearly feel the resistance of the tightening bolt 62, so as to stop the further tightening operation in time to prevent stripping.

[0031] In addition, the flexible gasket 65 can reduce the vibration force experienced by the connecting parts in this area when they are working, thereby improving the stability between the connecting parts in this area.

[0032] Preferably, a ring of positioning posts 66 is installed at equal intervals on the outer edge of the circular holes on the opposite side of the two side plates 5. The end of the positioning post 66 away from the side plate 5 is a semi-circular structure, and the semi-circular end of the positioning post 66 is in contact with the outer wall of the rotating block 7.

[0033] When the gripper 1 clamps, it will drive the fixed block 6 to rotate synchronously. When the fixed block 6 rotates, it will drive the positioning post 66 to rotate. When the positioning post 66 rotates, it will press against the outer wall of the rotating block 7. In this way, the fixed block 6 will not wobble from side to side when it rotates.

[0034] In practical use, when the gripper 1 needs to be replaced, firstly, remove one of the tightening bolts 62. Then, pull the other tightening bolt 62. Under the pulling force, the tightening bolt 62, through its secure connection with the connecting rod 61, drives the connecting rod 61 to move synchronously. As the connecting rod 61 moves, it gradually disengages from the preset mounting holes in the fixing block 6 and the rotating block 7. Once the connecting rod 61 is completely disengaged, the connection between the side plate 5 and the fixing plate 8 is released, and the gripper 1 is smoothly removed from the telescopic arm 11.

[0035] Compared with the traditional method of welding and then disassembling, this operation avoids tedious processes such as cutting and grinding, which not only greatly shortens the disassembly time and reduces labor intensity, but also effectively avoids damage to other parts of the equipment, thus greatly meeting the convenience requirements of actual operation.

[0036] When installing gripper 1, first place the rotating block 7 between the two fixed blocks 6. The side wall of the rotating block 7 will contact the positioning post 66 on the outer wall of the fixed block 6. Through this positioning method, the through hole on the rotating block 7 can be quickly aligned with the through hole on the fixed block 6. Then, smoothly insert the connecting rod 61 into the aligned through hole of the rotating block 7 and the fixed block 6. On both sides of the fixed block 6, tighten a tightening bolt 62 with a wrench. As the tightening bolt 62 rotates, the pressure post 63 on one side gradually presses against the outer wall of the gasket 65. When the pressure post 63 and the gasket 65 are tightly fitted, generating sufficient friction and pressure, the tightening bolt 62 and the fixed block 6 are firmly connected, and gripper 1 is successfully installed with the telescopic arm 11. This connection method reduces complex positioning and tightening steps, effectively simplifies the installation process of gripper 1, reduces the professional skills required of workers, greatly improves installation efficiency, and provides great convenience for equipment maintenance and adjustment in actual production.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
