[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a slope protection excavation device for water conservancy and hydropower engineering construction, including an excavator body 1. A compaction mechanism 2 is connected to the connecting rod of the excavator body 1 by a pin. A disassembly and assembly mechanism 3 is fixedly connected to the outer surface of the compaction mechanism 2. The disassembly and assembly mechanism 3 includes a pin 301 that is slidably connected to the outer surface of the bucket body 201. A connecting plate 309 is fixedly connected to the outer surface of the pin 301, and a toothed groove 303 is opened on the outer surface of the pin 301. A limit block 304 is engaged with the outer surface of the toothed groove 303.

[0032] Specifically, the outer surface of the pin 301 is slidably connected to the limiting plate 310, the outer surface of the limiting plate 310 is fixedly connected to the fixed housing 302, the inner wall of the fixed housing 302 is slidably connected to the lifting frame 305, the outer surface of the lifting frame 305 is fixedly connected to the outer surface of the limiting block 304, the inner wall of the fixed housing 302 is rotatably connected to the bidirectional bolt 307, the outer surface of the bidirectional bolt 307 is threadedly connected to the outer surface of the lifting frame 305, the outer surface of the bidirectional bolt 307 is fixedly connected to the worm gear 308, the outer surface of the worm gear 308 is meshed with the handle 306, one end of the handle 306 passes through the outer surface of the fixed housing 302 and is fixedly connected to the knob 311.

[0033] Furthermore, by utilizing the coordinated operation of components such as the knob 311, handle 306, worm gear 308, double-acting bolt 307, and lifting frame 305, the bucket body 201 can be quickly disassembled and assembled. When encountering different geological conditions that require bucket replacement, operators can quickly complete the replacement work, improving construction efficiency and avoiding delays in project progress due to excessively long bucket replacement times.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The tamping mechanism 2 includes a bucket body 201 connected to the connecting rod of the excavator body 1. A fixed frame 202 is fixedly connected to the outer surface of the bucket body 201. A fixed plate 207 is fixedly connected to the inner wall of the fixed frame 202. A first hydraulic telescopic rod 203 is fixedly connected to the outer surface of the fixed plate 207. An extrusion plate 206 is fixedly connected to the output end of the first hydraulic telescopic rod 203 through the outer surface of the bucket body 201.

[0036] The specific compaction mechanism 2 also includes a protective frame 204 fixedly connected to the outer surface of the bucket body 201. A second hydraulic telescopic rod 205 is fixedly connected to the inner wall of the protective frame 204. The output end of the second hydraulic telescopic rod 205 is fixedly connected to the outer surface of the extrusion plate 206. A through hole 208 is opened on the outer surface of the first hydraulic telescopic rod 203, and a gap is left between the outer surface of the first hydraulic telescopic rod 203 and the inner wall of the fixed frame 202.

[0037] The first hydraulic telescopic rod 203 and the second hydraulic telescopic rod 205 are further used to compress and shape the slope, which not only enhances the structural stability of the slope, but also effectively prevents the collapse of the inner side of the slope, thus improving the safety and reliability of the project.

[0038] Working Principle: The excavator body 1 achieves precise control of the compaction mechanism 2 through its hydraulic system and control panel. In water conservancy and hydropower engineering construction, the excavator body 1 is first adjusted to a suitable excavation position and angle. The bucket body 201 in the compaction mechanism 2 is connected to the connecting rod of the excavator body 1 via a pin, ensuring that the angle and depth of the bucket can be flexibly adjusted during excavation. When the excavator starts working, the control panel activates the first hydraulic telescopic rod 203 and the second hydraulic telescopic rod 205. The output ends of these two telescopic rods push the extrusion plate 206 to move towards the inner side of the slope, thereby compressing and shaping the slope. This compression not only enhances the structural stability of the slope but also effectively prevents the collapse of the inner side of the slope.

[0039] When different specifications of the bucket body 201 need to be replaced due to different geological conditions, the operation procedure is as follows: First, the operator rotates the knob 311. The knob 311 is fixedly connected to the handle 306, so the rotation of the knob 311 will drive the handle 306 to rotate synchronously. The handle 306 meshes with the worm gear 308. When the handle 306 rotates, it drives the worm gear 308 to rotate. The worm gear 308 is fixed on the double-acting bolt 307, which in turn causes the double-acting bolt 307 to rotate. The double-acting bolt 307 is threadedly connected to the lifting frame 305. When the double-acting bolt 307 rotates, the lifting frame 305 slides along the thread direction on the inner wall of the fixed housing 302. Since the lifting frame 305 is fixedly connected to the limiting block 304, the sliding of the lifting frame 305 will drive the limiting block 304 to move, causing the limiting block 304 to separate from the toothed groove 303 on the pin 301. At this point, the pin 301 is no longer restricted by the limiting block 304, allowing the limiting plate 310 and the pin 301 to be easily separated, thus enabling quick replacement of the bucket body 201 with different specifications. After replacement, reverse the above steps to re-engage the limiting block 304 with the toothed groove 303 of the pin 301, securing the bucket body 201 and ensuring a stable connection of the bucket body 201 during subsequent operations.

[0040] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
