[0002] The bucket teeth of an excavator are important parts of the excavator. They are similar to human teeth and are also vulnerable parts. They are composed of a tooth seat and a tooth tip, which are connected by a pin. Since the tooth tip is the part that fails due to wear, you only need to replace the tooth tip.

[0003] Bucket teeth need to be calcined many times during the production process. During the calcination process, the bucket teeth are clamped and fixed manually, the workstations are transferred and calcined, which is very labor-intensive and inefficient. Some bucket tooth processing equipment uses corresponding molds when maintaining the workstations during the calcination of bucket teeth. First, the contact area between the bucket teeth and the mold is large, which greatly reduces the calcination efficiency and makes demolding more difficult.

[0034] The driving mechanism drives the sliding frame 3 to pass through the bottom of the bucket tooth loading mechanism, and the bucket tooth loading mechanism loads the bucket teeth to be processed into the transfer cylinder 4 in the bucket tooth material transfer unit in the sliding frame 3;

[0035] The bucket tooth material transfer unit includes a rotating barrel 4, the vertical height difference between the top of the heating box 12 and the bottom of the rotating barrel 4 is less than 0.2 cm, each rotating barrel 4 is fixed to each other and to the vertical inner wall of the sliding frame 3, the top view cross section of the rotating barrel 4 is rectangular, and the bottom size of the rotating barrel 4 is larger than the top size, and the bottom inner wall of the rotating barrel 4 is bucket-shaped and gathers upward, and side holes are formed on both sides of the top cylinder of the rotating barrel 4, and sliding splints 5 are slidably connected in the side holes, and a plurality of support rods 6 are fixedly installed on the side where the two sliding splints 5 are close to each other , and the length of each support rod 6 matches the shape of both sides of the bucket teeth. The outer vertical sliding sleeve of the rotating barrel 4 is provided with a vertical sliding ring 7 for controlling the horizontal movement of the two sliding clamping plates 5. Each vertical sliding ring 7 is fixed to each other. The ring bodies on both sides of the vertical sliding ring 7 are provided with oblique sliding cavities, and a horizontal circular shaft 9 is slidably connected in the sliding cavity.
