[0046] This utility model provides a curbstone removal device for installation on the bucket 1 of an excavator. The front end of the bucket 1 is provided with multiple toothed seats 11, and the curbstone removal device is fixedly connected to the toothed seats 11. The curbstone removal device will be described in detail below through embodiments.

[0047] Figure 1 This invention illustrates one embodiment of the curbstone removal device provided by this utility model.

[0048] In this embodiment, the curbstone removal device includes a base plate 2, multiple tooth tips 3, a shovel plate 4, and a connecting structure 5.

[0049] The base plate 2 is used to fit on the bottom of the bucket 1. Multiple tooth tips 3 are used for detachable connection with corresponding tooth seats 11, and the multiple tooth tips 3 are fixedly connected to the top surface of the base plate 2. A shovel plate 4 is located on one side of the base plate 2, with its front end extending beyond the front ends of the multiple tooth tips 3. A connecting structure 5 connects the base plate 2 and the shovel plate 4.

[0050] Specifically, the bucket 1 has multiple tooth seats 11 facing forward, and multiple tooth tips 3 arranged laterally, each corresponding to one of the tooth seats 11. The corresponding tooth tips 3 and tooth seats 11 are detachably fixedly connected to distribute the force. After connection, the multiple tooth tips 3 also face forward. The multiple tooth tips 3 are close to the front side of the bottom plate 2, which rests against the bottom of the bucket 1. The length direction of the shovel plate 4 is consistent with the front-rear direction of the bucket 1. In the front-rear direction, the front end of the shovel plate 4 extends beyond the front end of the bucket 1, facilitating the excavation of curb stones. The shovel plate can be made of a long strip of metal.

[0051] Multiple tooth tips 3 of the curbstone removal device are fixedly connected to the corresponding tooth seats 11 of the bucket 1. Then, the excavator is operated to remove the curbstone located at the edge of the road using the front end of the shovel plate 4. The shovel plate 4 is connected to one side of the base plate 2 through the connecting structure 5, which can better adapt to the position of the curbstone. As the excavator travels along the road, with the curbstone located at the edge of the road, the shovel plate 4 is closer to the curbstone, making it easier to operate. The shovel plate 4 applies force from the end of the curbstone to dig it out. The excavated curbstone is not easily damaged, has a high reuse rate, saves materials, and also avoids damage caused by the bucket 1 directly applying force to the curbstone.

[0052] The curbstone removal device has a simple structure and low manufacturing cost. Installing the curbstone removal device on an excavator to remove curbstones can replace the traditional manual removal method, which can save manpower, speed up the process, improve the efficiency of road engineering operations, reduce the breakage rate of curbstones, and reduce material waste and cleaning costs.

[0053] The base plate 2 and the shovel plate 4 are parallel, and the multiple tooth tips 3 all face the front of the base plate 2. After being installed on the bucket 1, the multiple tooth tips 3 are aligned with the multiple tooth seats 11, so that the front end of the shovel plate 4 is aligned with the front end of the bucket 1. The excavator operator can judge the orientation of the shovel plate 4 based on the orientation of the bucket 1.

[0054] Depending on the actual construction situation, the shovel plate 4 can be connected to the left or right side of the base plate 2 via the connecting structure 5 to facilitate the removal of the curb stone on the corresponding side.

[0055] Fasteners 6 are mounted on multiple tooth tips 3, and the tooth tips 3 and their corresponding tooth seats 11 are detachably fixedly connected by the fasteners 6. The fasteners 6 can be bolts, pins, etc. The connection method between the tooth tips 3 and the tooth seats 11 is prior art well known to those skilled in the art. The tooth tips 3 can be fixedly connected to the base plate 2 by welding.

[0056] The base plate 2, the shovel plate 4, and the connecting structure 5 can be a single integrated structure, ensuring high stability. The connecting structure 5 can be a connecting rod, a connecting plate, etc. The connecting structure 5 can be fixedly connected to the base plate 2 and the shovel plate 4 by welding. Alternatively, the connecting structure 5 can be detachably connected to the base plate 2 and the shovel plate 4, for example, by fixing it with a bolt and nut assembly.

[0057] In one specific embodiment, the connecting structure 5 includes multiple fixed connecting rods 50, one end of which is connected to the base plate 2 or the tooth tip 3, and the other end is connected to the shovel plate 4. The multiple fixed connecting rods 50 are distributed along the front-back direction of the shovel plate 4 to increase the stability of the shovel plate 4.

[0058] Figure 2 and Figure 3 Embodiment 2 of the curbstone removal device provided by this utility model is shown.

[0059] The difference between this embodiment and Embodiment 1 lies in the connection structure 5.

[0060] In this embodiment, the connecting structure 5 includes a first connecting rod 51 and a second connecting rod 52. One end of the first connecting rod 51 is fixedly connected to the base plate 2, and the other end is connected to the shovel plate 4 through the first connecting structure 53. The second connecting rod 52 includes a fixed screw 521, a movable screw 522, and a threaded sleeve 523. The opposite ends of the threaded sleeve 523 are respectively provided with internal threads in opposite directions. One end of the threaded sleeve 523 is threadedly connected to the fixed screw 521, and the other end is threadedly connected to the movable screw 522. Rotating the threaded sleeve 523 in both directions can extend or shorten the second connecting rod 52. The end of the fixed screw 521 away from the threaded sleeve 523 is fixedly connected to the base plate 2, and the end of the movable screw 522 away from the threaded sleeve 523 is connected to the shovel plate 4 through the second connecting structure 54. By rotating the threaded sleeve 523 to extend or retract the second connecting rod 52, the angle between the shovel plate 4 and the base plate 2 can be adjusted.

[0061] Specifically, the first connecting structure 53 is a rotating shaft or bolt and nut assembly perpendicular to the shovel plate 4, allowing the angle between the first connecting rod 51 and the shovel plate 4 to be adjustable; the second connecting structure 54 is a rotating shaft or bolt and nut assembly perpendicular to the shovel plate 4, allowing the angle between the second connecting rod 52 and the shovel plate 4 to be adjustable. Two through holes can be provided on the shovel plate 4 to connect the first connecting structure 53 and the second connecting structure 54 respectively. If the first connecting structure 53 and the second connecting structure 54 are bolt and nut assemblies, the bolt and nut assemblies can be disassembled or loosened first, and then the length of the second connecting rod 52 can be adjusted using the threaded sleeve 523.

[0062] The first connecting rod 51 is located behind the second connecting rod 52. One end of the first connecting rod 51 is fixedly connected to the base plate 2, and the other end is close to the rear end of the shovel plate 4. One end of the second connecting rod 52 is fixedly connected to the base plate 2, and the other end is spaced from the front end of the shovel plate 4 to allow for a greater range of adjustment of the front end of the shovel plate 4.

[0063] Excavators have certain blind spots. When working on curves, if the position of the shovel plate 4 is blocked, the angle of the shovel plate 4 can be adjusted through the threaded sleeve 523 to bring the front end of the shovel plate 4 into the field of vision of the excavator operator, which facilitates the construction operation.

[0064] Figure 4 , Figure 5 and Figure 6 Embodiment 3 of the curbstone removal device provided by this utility model is shown.

[0065] The difference between this embodiment and Embodiment 1 or Embodiment 2 is that it also includes a reinforcement component 7.

[0066] Two reinforcement components 7 are provided, located on opposite sides of the bucket 1. Each reinforcement component 7 includes a snap-fit ​​plate 71 and a reinforcement link 72, which can be one or more. The snap-fit ​​plate 71 engages with the edge of the side plate 12 on the corresponding side of the bucket 1, and the reinforcement link 72 connects the bottom plate 2 and the snap-fit ​​plate 71. The two reinforcement components 7, connected between the bottom plate 2 and the side plate 12 of the bucket 1, increase the stability of the bottom plate 2 and distribute the force across the bottom of the bucket 1, the side plate 12, and the tooth holder 11, thereby reducing wear on the tooth holder 11 and the tooth tip 3, without altering the structure of the bucket 1.

[0067] Since the edges of the side plates 12 on both sides of the bucket 1 are beveled, the snap-fit ​​plate 71 can be set at an angle consistent with the inclination angle of the edge of the side plate 12. The cross-section of the snap-fit ​​plate 71 is an "L" shaped structure or a "U" shaped structure, which can better engage with the side plate 12.

[0068] The reinforcing link 72 includes a first screw 721, a second screw 722, and an adjusting sleeve 723. The top and bottom ends of the adjusting sleeve 723 are respectively provided with internal threads in opposite directions. The top end of the adjusting sleeve 723 is threadedly connected to the bottom end of the first screw 721, and the bottom end of the adjusting sleeve 723 is threadedly connected to the top end of the second screw 722. Rotating the adjusting sleeve 723 allows the reinforcing link 72 to extend or retract, adjusting its length. The top end of the first screw 721 is hinged to a locking plate 71, and the tilt angle of the locking plate 71 is adjustable. The bottom end of the second screw 722 is connected to the base plate 2. The bottom end of the second screw 722 can be welded to the base plate 2 or detachably fixed. By adjusting the length of the reinforcing link 72 and the tilt angle of the locking plate 71, the reinforcing assembly 7 can adapt to different models of excavator buckets 1, exhibiting high versatility.

[0069] Specifically, the reinforcement component 7 includes a snap-fit ​​plate 71 and two reinforcing connecting rods 72. The snap-fit ​​plate 71 is configured as a strip structure, and the two reinforcing connecting rods 72 are respectively located near the opposite ends of the snap-fit ​​plate 71. Adjusting the length of the two reinforcing connecting rods 72 can adjust the tilt angle of the snap-fit ​​plate 71, ensuring that the tilt angle of the snap-fit ​​plate 71 is consistent with the edge of the side plate 12 of the bucket 1, so as to achieve stable engagement.
