[0002] Bucket teeth are composed of a tooth seat and a tooth tip. They are used to be installed on the bucket of an excavator. They are responsible for the front-end excavation work. They are similar to human teeth and are easily damaged parts. They need to be replaced after long-term use. They are generally divided into sand casting, forging casting and precision casting. Precision casting has the advantages of being strong and wear-resistant, which is superior to the other two casting methods.
[0003] Existing excavator bucket teeth are generally installed by fixed welding, and the degree of the bucket teeth cannot be adjusted. When the bucket teeth are damaged, they need to be replaced as a whole, which is relatively wasteful. In view of this, we need an excavator bucket tooth with an adjustment structure.

DETAILED DESCRIPTION
[0021] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: an excavator bucket tooth with an adjustment structure, comprising a bucket tooth 1, a mounting seat 2 is arranged on the side of the bucket tooth 1, an adjusting rod 3 is fixedly installed on the outer wall of the bucket tooth 1, the adjusting rod 3 passes through the interior of the mounting seat 2, a baffle 4 is fixedly installed on the outer wall of the adjusting rod 3, and by continuously rotating the bidirectional threaded rod 5 counterclockwise, the two limit rods 63 can continue to be brought together to release the limit of the baffle 4, so as to facilitate the replacement of the bucket tooth 1, a bidirectional threaded rod 5 is rotatably connected to the inner wall of the mounting seat 2, and an adjustment mechanism 6 is arranged inside the mounting seat 2.
[0022] In this embodiment, an adjustment mechanism 6 is provided inside the mounting seat 2, and the threaded block 61 in the adjustment mechanism 6 can drive the limit rod 63 to be clamped in the inside of the clamping groove 69, so as to facilitate the adjustment of the position of the bucket tooth 1 and the replacement of the bucket tooth 1. During installation, the outer wall of the extrusion plate 65 is squeezed by the edge of the clamping groove 69, so that the extrusion plate 65 can drive the protrusion 68 on the outer wall of the fixing block 67 to rotate, and then the protrusion 68 is clamped in the inside of the groove 610, so that the position of the adjustment rod 3 can be clamped and fixed, which is convenient for the use of the bucket tooth 1.
[0023] The above-mentioned adjusting mechanism 6 includes a threaded block 61, which is threadedly connected with the bidirectional threaded rod 5. The bidirectional threaded rod 5 is screwed clockwise to make the two threaded blocks 61 move back to back, which is convenient for installation. The threaded block 61 is slidably connected with the inner wall of the mounting seat 2. A fixing plate 62 is fixedly installed on the outer wall of the threaded block 61. A limiting rod 63 is fixedly installed on the outer wall of the fixing plate 62. The installation is completed by clamping the limiting rod 63 in the inside of the slot 69. A rotating rod 64 is rotatably connected to the inner wall of the limiting rod 63. An extrusion plate 65 is fixedly sleeved on the outer wall of the rotating rod 64. The outer wall of the extrusion plate 65 is squeezed by the edge of the slot 69. The extrusion plate 65 is able to drive the protrusion 68 on the outer wall of the fixing block 67 to rotate. The outer wall of the extrusion plate 65 is fixedly connected to one end of the load-bearing spring 66. The other end of the load-bearing spring 66 is fixedly connected to the inner wall of the limiting rod 63. A fixing block 67 is installed on the outer wall of the extrusion plate 65. A protrusion 68 is fixedly installed on the outer wall of the fixing block 67. The protrusion 68 is clamped in the inside of the groove 610 to fix the position of the adjusting rod 3. A clamping groove 69 is provided on the outer wall of the adjusting rod 3. The clamping grooves 69 are distributed in an array on the adjusting rod 3. A groove 610 is provided on the adjusting rod 3. The grooves 610 are arranged on both sides of the clamping groove 69.
[0024] The two-way threaded rod 5 is screwed clockwise to make the two threaded blocks 61 move in opposite directions, and the threaded block 61 drives the limiting rod 63 on the outer wall of the fixing plate 62 to move in the direction of the adjusting rod 3, so that the limiting rod 63 is clamped in the inside of the clamping groove 69 for limiting. At the same time, the outer wall of the extrusion plate 65 is squeezed by the edge of the clamping groove 69, so that the extrusion plate 65 drives the protrusion 68 on the outer wall of the fixing block 67 to rotate. Finally, the protrusion 68 is clamped in the inside of the groove 610, so that the position of the adjusting rod 3 is clamped and fixed, which is convenient for the use of the bucket tooth 1. When the position of the bucket tooth 1 needs to be adjusted, the two-way threaded rod 5 is rotated counterclockwise to make the limiting rod 63 move out of the inside of the clamping groove 69, so that the limit is released for convenient adjustment. Continuing to rotate the two-way threaded rod 5 counterclockwise can make the two limiting rods 63 continue to close together to release the limit of the baffle 4, which is convenient for replacing the bucket tooth 1.
[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
