[0002] A bucket excavator is an excavating machine with the bucket as its core component. It completes excavation operations by driving a linkage mechanism through hydraulic cylinders. The bucket is welded together from components such as a toothed plate, bottom plate, and side plates, and is equipped with ear plates. However, when the bucket is subjected to uneven force, the ear plates will bear additional leverage stress, causing local stress to exceed the material's yield strength. At this time, the welded area of ​​the ear plate and the edge teeth are prone to plastic deformation due to stress concentration. As the core connecting component between the bucket and the boom, the ear plate needs to transmit multi-directional forces during excavation. Bending of the bucket ear plate will seriously affect the use of the bucket. To facilitate the straightening operation of the bucket ear plates, a bucket ear plate straightening device is provided.

The following describes embodiments of the invention based on its overall structure.

[0019] Please see Figures 1 to 7In this embodiment of the invention, a bucket ear plate straightening device includes symmetrically arranged mounting plates 1. The mounting plates 1 straighten the ear plates 3 on the bucket 2 through a straightening mechanism 4. The straightening mechanism 4 includes a side plate 401, which is fixedly connected to one side of the mounting plate 1. The outer wall of the side plate 401 has a movable groove 402, and the inner wall of the movable groove 402 is slidably connected to a movable seat 403. One end of the side plate 401 is rotatably connected to a rotating column 404. The outer wall of the rotating column 404 is fixedly connected to a first threaded rod 405, which passes through the movable seat 403. A cylinder 406 is installed on the outer wall of the movable seat 403. The output end of the cylinder 406 is fixedly connected to a straightening plate 407 with a "∩" shape. One end of the straightening plate 407 is provided with a positioning plate 408, and the position of the positioning plate 408 is adjusted by an adjustment mechanism 5. The straightening mechanism 4 also includes a displacement groove 409. A groove 409 is formed on the outer wall of the mounting plate 1. A displacement rod 410 is slidably connected to the inner wall of the displacement groove 409. A clamping plate 411 is fixedly connected to the outer wall of the displacement rod 410. A locking block 412 extending into the inner cavity of the displacement groove 409 is slidably connected inside the mounting plate 1. The locking block 412 extends out of the mounting plate 1. A first spring 413 is connected between the locking block 412 and the mounting plate 1. A sliding groove 414 is formed on the outer wall of the locking block 412 inside the mounting plate 1. A sliding plate 415 extending into the inner cavity of the sliding groove 414 is slidably connected inside the locking block 412. A rotating block 419 is rotatably connected to the outer wall of the locking block 412. A second bevel gear 418 is fixedly connected to one end of the rotating block 419. A first bevel gear 417 is rotatably connected to the outer wall of the second bevel gear 418 inside the locking block 412. A second threaded rod 416 is fixedly connected to one end of the first bevel gear 417. The second threaded rod 416 passes through the sliding plate 415.

[0020] In this embodiment: when straightening the ear plate 3, the side plate 401 is placed on the outer wall of the bucket 2 and located on one side of the ear plate 3. The mounting plate 1 is placed in the inner cavity of the bucket 2. The clamping plate 411 is located on one side of the bucket 2. Then, the clamping plate 411 is pushed to move. The movement of the clamping plate 411 causes the displacement rod 410 to slide in the displacement groove 409. The clamping plate 411 and the mounting plate 1 are clamped together on one side of the bucket 2 (to increase the clamping firmness, anti-slip rubber pads can be provided on the clamping surfaces opposite to the mounting plate 1).

[0021] At this time, the locking block 412 is engaged with the displacement rod 410 by the elastic force of the first spring 413, thereby fixing the position between the clamping plate 411 and the mounting plate 1. Then, the rotating block 419 is rotated, which drives the second bevel gear 418 to rotate. The second bevel gear 418 drives the first bevel gear 417 to rotate. The first bevel gear 417 drives the second threaded rod 416 to rotate. The second threaded rod 416 drives the slide plate 415 to move. The slide plate 415 slides in the slide groove 414. The slide plate 415 slides to the end of the slide groove 414 away from the displacement groove 409, so that the locking block 412 cannot move away from the displacement groove 409, thereby reinforcing the position of the clamping plate 411.

[0022] After completion, the rotating column 404 can be rotated. The rotation of the rotating column 404 drives the first threaded rod 405 to rotate. The rotation of the first threaded rod 405 drives the movable seat 403 to slide within the movable groove 402. The displacement of the movable seat 403 causes the cylinder 406 and the straightening plate 407 to move synchronously, so that the outer side or hollow part of the straightening plate 407 is aligned with the ear plate 3 and contacts the part to be straightened. By adjusting the parts in the adjusting mechanism 5, the position of the positioning plate 408 is adjusted. The plane on which the side of the ear plate 3 to be straightened is located is the correct position of the ear plate 3 facing the positioning plate 408 after straightening. The cylinder 406 is started. The cylinder 406 rotates and drives the straightening plate 407 to move. The straightening plate 407 performs a squeezing and straightening operation on the ear plate 3 until the ear plate 3 is aligned with the positioning plate 408, thus completing the straightening operation.

[0023] When the ear plate 3 is straightened inward, the outer side wall of one end of the straightening plate 407 contacts the outer side of the ear plate 3, pushing the ear plate 3 to deform; when the ear plate 3 is straightened outward, the ear plate 3 is moved to the inner wall of the hollow part of the straightening plate 407, the straightening plate 407 moves outward, causing the ear plate 3 to deform.

[0024] When disassembling the mounting plate 1, rotating the rotating block 419 drives the sliding plate 415 to reset, allowing the locking block 412 to move away from the displacement groove 409. Pushing the locking block 412 to move causes compression on the first spring 413, separating the locking block 412 from the displacement rod 410, canceling the positioning of the clamping plate 411, and pushing the clamping plate 411 away from the mounting plate 1 to move. At this time, the mounting plate 1 can be moved off the bucket 2.

[0025] Please refer to this carefully. Figures 6 to 7The adjusting mechanism 5 includes an adjusting groove 501, which is located inside the movable seat 403. A fixing groove 502 is provided on one side of the inner wall of the adjusting groove 501. An adjusting frame 503 is slidably connected to the inner wall of the adjusting groove 501. A fixing block 504 extending to the outer wall of the adjusting frame 503 is slidably connected inside the adjusting frame 503. A second spring 505 is connected between the fixing block 504 and the adjusting frame 503. An adjusting column 508 is rotatably connected to the outer wall of the adjusting frame 503. The bottom end of the adjusting column 508 is fixedly connected to... There is a third threaded rod 507, and a pressing rod 506 is connected to the outer wall of the third threaded rod 507.

The third threaded rod 507 passes through the toothed plate 511.

[0026] In this embodiment: when adjusting the position of the positioning plate 408, the positioning plate 408 is pushed to slide in the transverse groove 509 to move the positioning plate 408 laterally; the adjusting frame 503 is pushed to slide in the adjusting groove 501 to move the positioning plate 408 vertically, thereby adjusting the position of the positioning plate 408. Then, the adjusting column 508 is rotated, which drives the third threaded rod 507 to rotate. The rotation of the third threaded rod 507 drives the toothed plate 511 and the lower pressure rod 506 to move synchronously. The lower pressure rod 506 moves downward and pushes the fixing block 504 to move. The fixing block 504 moves and inserts into the fixing groove 502, fixing the adjusting frame 503 in the adjusting groove 501. The toothed plate 511 moves downward and contacts the toothed block 510. The toothed plate 511 and the toothed block 510 engage, fixing the positioning plate 408 in the transverse groove 509, thereby fixing the position of the positioning plate 408. This design facilitates the adjustment of the position of the positioning plate 408.
