[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2 , which is the first embodiment of the present invention, and this embodiment provides a fan-type excavating cutter disc device, which includes a bearing unit 100, the bearing unit 100 includes a mounting column 101 and a rotating disk 102 rotatably arranged below the mounting column 101; a clamping unit 200, the clamping unit 200 includes a slide 201 and a clamping claw 202 fixedly installed below the slide 201; an excavating unit 300, the excavating unit 300 includes a first component 301 and a second component 302 rotating at one end of the first component 301.

[0028] The carrying unit 100 provides installation conditions for the clamping unit 200 and the digging unit 300 and provides support for them. Through the setting of the clamping unit 200, it can cooperate with the carrying unit 100, so that the clamping unit 200 slides on the carrying unit 100, so that it can drive the digging unit 300 to rise. Through the setting of at least two digging units 300, the cutter disc spliced ​​by the digging unit 300 can be disassembled and folded, which is conducive to storage. In the case of mud and water appearing at the cutter disc, it is also convenient to replace the first tool 301d or the second tool 302d.

[0029] Specifically, a mounting groove 101 a is formed on the outer side of the mounting column 101 , and electric slide rails 101 b are symmetrically fixedly mounted on both sides of the mounting groove 101 a , and the electric slide rails 101 b are slidably matched with the slide seat 201 .

[0030] By setting the electric slide rail 101b, the clamping unit 200 can be driven to move up and down, thereby driving the single excavation unit 300 to move, and realizing the lifting and lowering of the excavation unit 300. The electric slide rail 101b is controlled by the shield machine control system. The control system is a prior art and will not be described in detail here.

[0031] Specifically, at least two convex grooves 102a are evenly formed on the outer ring of the rotating disk 102, and first electric push rods 102b are symmetrically installed inside the two sides of the convex grooves 102a.

[0032] The number of convex grooves 102a can be determined according to actual usage, wherein the number of convex grooves 102a is the same as the number of excavation units 300, the setting of the convex grooves 102a can cooperate with the first component 301, and the first component 301 is engaged and limited by the first electric push rod 102b, so that the first component 301 can be stably located in the convex groove 102a, wherein the first electric push rod 102b is controlled by a control system.

[0033] Example 2

[0034] Reference Figure 3-4 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes a first component 301 including a straight rib 301a, two first plug holes 301c symmetrically opened on both sides of one end of the straight rib 301a, a first disc 301e fixed to one end of the straight rib 301a, and a blocking member 301h arranged on the outer ring of the first disc 301e, two grooves 301b are symmetrically opened at the bottom of the straight rib 301a, and a first tool 301d is arranged at the bottom of the straight rib 301a.

[0035] Furthermore, the straight rib 301a is matched with the convex groove 102a, the raised part of the convex groove 102a is matched with the groove 301b, the first electric push rod 102b is plugged into the first socket 301c, and a clamping groove 301i is provided on the top of the straight rib 301a, which is matched with the clamping claw 202.

[0036] The mutual cooperation between the groove 301b and the convex groove 102a can limit the straight rib 301a, and through the plug-in cooperation between the first socket 301c and the first electric push rod 102b, the straight rib 301a can be stably fixed on the rotating disk 102 to realize the excavation of soil.

[0037] The first tool 301d is detachably installed, and the specific number can be set according to actual usage. The first tool 301d has a corresponding driving device, and the specific installation position can be determined according to the spatial layout during actual use, and its driving device is controlled by a control system.

[0038] Specifically, a stepper motor 301f is fixedly installed on the top of the first disk 301e, and a rotating shaft 301g is fixedly connected to the output end of the stepper motor 301f, and the rotating shaft 301g is rotatably matched with the first disk 301e.

[0039] Furthermore, the blocking member 301h includes a blocking block 301h-1 fixed to the outer ring of the first disk 301e, a limiting groove 301h-2 is provided at the bottom of the blocking block 301h-1, and a second electric push rod 301h-3 is installed inside one side of the limiting groove 301h-2.

[0040] The first disc 301e drives the rotating shaft 301g to rotate, which can provide the power required for the rotation of the second component 302 and provide support for the second component 302. The outer arc surface of the blocking block 301h-1 is tangent to the farthest point of the first disc 301e from the straight rib 301a, and the outer arc surface of the blocking block 301h-1 is tangent to the outer arc surface of the second component 302 after it is unfolded, forming a ring, ensuring that the soil can be excavated smoothly through the device. The blocking block 301h-1 is close to the lower part of one side of the first disc 301e, and cooperates with the second component 302 for rotation, and is tightly attached to the outer side of the second component 302, which can ensure the smooth operation of the second component 302 while ensuring that no soil enters to affect its flexibility.

[0041] The limiting groove 301h-2 can cooperate with the second component 302 and fix the second component 302 through the second electric push rod 301h-3. At the same time, the side of the limiting groove 301h-2 close to the rotating shaft 301g is set as an arc, and the arc takes the center of the second disc 302b as the center, which can ensure that the second component 302 can fit smoothly with it when rotating, so that the gap at the intersection is minimized, ensuring the stability of the connection and preventing mud and the like from accumulating therein.

[0042] When in use and during installation, first insert one end of the straight rib 301a with the groove 301b into the convex groove 102a. After insertion, open the first electric push rod 102b, insert the first electric push rod 102b into the first socket 301c, limit the first socket 301c, and after the installation is completed, install the first tool 301d to ensure the normal operation of the first tool 301d, and then install the second component 302.

[0043] Example 3

[0044] Reference Figure 3-4 , which is the third embodiment of the present invention, is based on the previous two embodiments, and also includes a second component 302 including an arc rib 302a, a second disc 302b fixed to one end of the arc rib 302a, a through hole 302c opened on the second disc 302b, a second tool 302d arranged at the bottom of the arc rib 302a, and an arc block 302e fixed to one end of the arc rib 302a away from the second disc 302b.

[0045] Furthermore, the second disc 302b is fixedly sleeved on the outer ring of the rotating shaft 301g through the through hole 302c. The second disc 302b is located below the first disc 301e. The arc rib 302a and the straight rib 301a have the same thickness.

[0046] Furthermore, a second plug hole 302f is provided on the top of the arc block 302e, and the second plug hole 302f is engaged with the second electric push rod 301h-3.

[0047] The second disk 302b is fixedly matched with the rotating shaft 301g through the through hole 302c. When the stepping motor 301f drives the rotating shaft 301g to rotate, it can also drive the second disk 302b to rotate. The outer arc surface of the arc rib 302a is tangent to the second disk 302b. On the one hand, it can ensure that after the excavation unit 300 is installed, the outer ring formed by the second component 302 is a circle, and the connected outer arc surface is relatively smooth. On the other hand, the rotation angle of the arc rib 302a can be limited. When the arc rib 302a rotates to form a circle with the blocking block 301h-1, the end of the arc rib 302a close to the second disk 302b will engage with the blocking block 301h-1, so that the maximum angle of the arc rib 302a to rotate outward is to form a ring with the outer side of the blocking block 301h-1.

[0048] The side of the arc block 302e away from the arc rib 302a is an arc surface, and the arc surface is concentric with the arc surface on the side of the limiting groove 301h-2 close to the first disk 301e. The two slide together to ensure the smooth rotation of the arc rib 302a while ensuring the stability of the connection. Through the plug-in setting of the second electric push rod 301h-3 and the second socket 302f, the blocking block 301h-1 can be effectively spliced ​​with the arc rib 302a to ensure its firmness and stability.

[0049] Further, as attached Figure 5 As shown, the limit groove 301h-2 is a groove with a protrusion in the middle, and the arc block 302e is a block with a groove in the middle. When the two are combined, not only can the connection between the two be made tighter, but the two can also form a mutually supporting state to ensure the normal operation of the device.

[0050] When in use or during installation, the through hole 302c is fixedly connected to the rotating shaft 301g, and after connection, the Figure 4 As shown, this is a schematic diagram of the structure of the second component 302 after being folded. When it needs to be unfolded, the stepper motor 301f is turned on and the second electric push rod 301h-3 is retracted. Then the stepper motor 301f drives the arc rib 302a to rotate outward through the rotating shaft 301g. When the arc rib 302a rotates to the maximum angle, the arc block 302e enters the limit groove 301h-2, and the second socket 302f corresponds to the second electric push rod 301h-3. Then the stepper motor 301f stops working, and the second electric push rod 301h-3 starts to extend and is inserted into the second socket 302f to fix the second socket 302f.

[0051] In summary, when in use, first install the excavating unit 300 on the ground according to the steps of Example 2 and Example 3. After the installation is completed, start excavation. During the excavation process, when the first tool 301d or the second tool 302d is damaged or needs to be replaced under different soil environments, first determine through the control system that the straight rib 301a of the first tool 301d or the second tool 302d needs to be replaced, rotate the rotating disk 102, rotate the excavating unit 300 to be replaced to correspond to the clamping claw 202, open the second electric push rod 301h-3 installed thereon and the second electric push rod 301h-3 matched with the arc rib 302a connected to the straight rib 301a, and then the entire excavating unit that needs to be disassembled is opened. The unit 300 is in an unconnected state, and then the stepper motor 301f is turned on to drive the arc rib 302a to rotate inward. When it rotates to a suitable position, the stepper motor 301f is stopped; then the first electric push rod 102b and the electric slide rail 101b are turned on, and the electric slide rail 101b drives the slide seat 201 to slide downward. When the clamping jaw 202 contacts the clamping groove 301i, the clamping jaw 202 is opened to cooperate with the clamping groove 301i to clamp the excavating unit 300. After clamping, the excavating unit 300 is transported upward by the electric slide rail 101b. After the first tool 301d or the second tool 302d is replaced, it is moved downward again, and then the excavating unit 300 is installed and fixed, and the device can continue to work.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
