[0066] like Figures 1 to 2 As shown, in one embodiment, the connecting mechanism 4 further includes a second connector 42, which is used to fix the first tooth 1 and the second tooth 2 onto the rake head 72.

[0067] In this embodiment, the second connector 42 enables a stable connection between the rake teeth 721 and the rake head 72, greatly ensuring the connectivity and strength of the rake teeth 721 and the rake head 72, and ensuring the working stability of the rake head 72 and the rake teeth 721.

[0068] As needed, the second connector 42 may include bolts, nuts, etc. Correspondingly, the first tooth 1, the second tooth 2 and the rake head 72 are provided with corresponding threaded holes, so as to realize the fixed connection of the first tooth 1, the second tooth 2 and the rake head 72, ensure the overall working strength and extend the service life.

[0069] like Figure 2 As shown, in one embodiment, the first connector 41 includes a first connecting block 411, a first bolt 412, and a second bolt 413. The first connecting block 411 is connected to the first tooth 1 via the first bolt 412, and the first connecting block 411 is connected to the second tooth 2 via the second bolt 413.

[0070] The second connector 42 includes a third bolt, through which the first tooth 1, the second tooth 2, and the rake head 72 are connected.

[0071] In this embodiment, the first connecting block 411 can be securely connected to the first tooth 1 and the second tooth 2 respectively by the first bolt 412 and the second bolt 413, and the first tooth 1, the second tooth 2 and the rake head 72 can be securely connected by the third bolt, which greatly ensures the overall tight connection effect and overall strength of the rake tooth 721 formed by this combination, and ensures the working stability of the rake tooth 721.

[0072] Correspondingly, the first tooth 1, the second tooth 2, the first connecting block 411, and the rake head 72 are provided with corresponding threaded holes, thereby realizing the fixed connection of the first tooth 1, the second tooth 2, and the first connecting block 411, as well as the fixed connection of the first tooth 1, the second tooth 2, and the rake head 72, ensuring overall working strength and extending service life.

[0073] like Figure 3 , Figure 5 As shown, in one embodiment, the first connecting block 411 has a mounting surface, the first tooth 1 is provided with a first contact surface 124, and the second tooth 2 is provided with a second contact surface 214. The mounting surface is in contact with the first contact surface 124 and the second contact surface 214 respectively.

[0074] In this embodiment, the mounting surface of the first connecting block 411 is respectively attached to the first mating surface 124 of the first tooth body 1 and the second mating surface 214 of the second tooth body 2, which greatly ensures the overall tight connection effect and overall strength of the rake teeth 721 formed by this combination, and ensures the working stability of the rake teeth 721.

[0075] It should be noted that when the first mating surface 124 and the second mating surface 214 are on the same surface, the mounting surface is set as a plane; when the first connecting surface and the second connecting surface are parallel to each other and are located on different surfaces, the mounting surface is set as a corresponding stepped surface.

[0076] like Figures 6-7 As shown, an excavator rake head includes:

[0077] The mounting mechanism 5 has a first connecting part 51 and a second connecting part 52 at its upper end. The first connecting part 51 is used to rotatably connect with the end of the excavator's stick, and the second connecting part 52 is used to rotatably connect with the connecting rod connected to the excavator's bucket cylinder. When the bucket cylinder is working, the connecting rod drives the mounting mechanism 5 to rotate around the first connecting part 51 on the first plane. The first connecting part 51 and the second connecting part 52 are located on the same side of the mounting mechanism 5.

[0078] The turntable mechanism 6 is connected to the lower end of the mounting mechanism 5;

[0079] The excavating mechanism 7 includes a mounting platform 71 and a rake head 72. The rake head 72 is mounted on the mounting platform 71, and the mounting platform 71 is connected to the turntable mechanism 6 for transmission. The turntable mechanism 6 is used to drive the excavating mechanism 7 to rotate circumferentially along the second plane. The first plane is perpendicular to the second plane, and the rake head 72 is equipped with any of the above-mentioned rake teeth 721.

[0080] In this embodiment, the digging mechanism 7 is installed at the lower end of the mounting mechanism 5 via the turntable mechanism 6. The turntable mechanism 6 enables the rake head 72 to rotate 360° on the second plane, ensuring that the rake head 72 can adjust the digging direction and angle according to actual working needs, thus providing work adaptability. The first connecting part 51 of the mounting mechanism 5 is rotatably connected to the end of the excavator's stick, and the second connecting part 52 of the mounting mechanism 5 is rotatably connected to the connecting rod connected to the excavator's bucket cylinder. This allows the mounting mechanism 5 to perform a flipping action around the first connecting part 51 on the first plane under the drive of the bucket cylinder. Since the first and second planes are set perpendicularly, the rake head 72 can adjust the digging direction and angle in different dimensions during operation, further improving its work adaptability and enabling it to quickly, efficiently, and conveniently complete various special digging tasks and digging work.

[0081] As needed, the rake head 72 can be mounted on the mounting platform 71 using fasteners such as bolts.

[0082] like Figures 6-7 As shown, in one embodiment, the turntable mechanism 6 includes:

[0083] The turntable body is fixedly connected to the mounting mechanism 5;

[0084] The drive unit is installed on the turntable body. The drive end of the drive unit is connected to the installation platform 71 for transmission. The drive unit is used to drive the installation platform 71 to rotate, so as to drive the rake head 72 to rotate around the turntable body.

[0085] In this embodiment, by installing the drive component on the turntable body, the working stability of the drive component is ensured. The drive end of the drive component is connected to the installation platform 71 through transmission, so that when the drive component is working, it drives the installation platform 71 to rotate and drives the rake head 72 to rotate circumferentially along the turntable body on the second plane, so that the rake head 72 can rotate 360° on the second plane, thereby improving the work adaptability and working stability.

[0086] It should be understood that the turntable body has a groove on the end face near the mounting platform 71, and a bearing is installed in the groove. The turntable body is bolted to the outer ring of the bearing, and the mounting platform 71 is bolted to the inner ring of the bearing. The driving component is a motor, and a gear is installed on the driving end of the motor. The mounting platform 71 is provided with a transmission part, and the transmission part has a groove corresponding to the gear. The inner wall of the groove is provided with internal teeth that mesh with the gear. Thus, when the driving component is working, the gear on the driving end of the driving component drives the mounting platform 71 to rotate.

[0087] like Figure 7As shown, in one embodiment, the rake head 72 includes a support member 722 and a plurality of rake teeth 721. The support member 722 is connected to the turntable mechanism 6 via a mounting platform 71, and the plurality of rake teeth 721 are mounted on the support member 722.

[0088] In this embodiment, a number of rake teeth 721 are installed on the support member 722 by the second connector 42, and the support member 722 is installed on the mounting platform 71 by fasteners, thereby achieving connection with the turntable mechanism 6. This ensures that when the turntable mechanism 6 is working, the support member 722 is driven to work by the mounting platform 71, so that all the rake teeth 721 on the support member 722 can move in unison and improve the overall strength.
