They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts and fishways and other different types of hydraulic structures to achieve their goals. In water conservancy and hydropower construction projects, it is necessary to conduct quality inspections on the ground pits, so it is necessary to break ground at the water conservancy project construction site.

[0021] Reference Figure 1-2An embodiment of the utility model provides an earth-breaking device for quality inspection of water conservancy and hydropower construction projects, comprising: a base 1, a counterweight box 2, an impact rod 3 and a cyclic lifting device. A universal wheel 4 is provided at the bottom of the base 1, and a telescopic hole 5 pointing vertically downward is provided in the middle of the base 1. The counterweight box 2 is slidably connected to the top of the base 1 and is located directly above the telescopic hole 5. The upper end of the impact rod 3 is fixedly connected to the bottom of the counterweight box 2, and the lower end of the impact rod 3 passes through the telescopic hole 5. The base 1 is located at the front and rear sides of the counterweight box 2 and is symmetrically provided with the cyclic lifting device for repeatedly lifting and releasing the counterweight box 2. The counterweight box 2 is a hollow structure, and the counterweight box 2 is respectively provided with a feed inlet 6 and a discharge outlet 7.

[0022] Wherein, the lower end of the impact rod 3 is a conical structure.

[0023] In the above technical scheme, the impact rod 3 is arranged at the bottom of the counterweight box 2, and the counterweight box 2 is a hollow structure and is respectively provided with a feed port 6 and a discharge port 7. When working, the staff adjusts the water injection amount in the counterweight box 2 according to the soil hardness of different environments, thereby adjusting the weight of the counterweight box 2 and the impact force of the impact rod 3 on the ground. After the adjustment is completed, the cyclic lifting devices on the front and rear sides of the counterweight box 2 synchronously lift and release the counterweight box 2 repeatedly, so that the impact rod 3 reciprocates up and down to impact and break the ground. The utility model can adjust the impact force when breaking the ground according to actual conditions, adapt to soils in different environments, have high ground breaking efficiency, and have a simple structure, can operate stably even in harsh environments, and is easy to maintain.

[0024] In some embodiments, the base 1 is provided with vertical guide rods 8 on the left and right sides of the counterweight box 2, and the left and right sides of the counterweight box 2 are provided with connecting ears 9 with through holes, respectively, and the connecting ears 9 are slidably connected to the outer periphery of the guide rods 8 through the through holes. This structural design allows the counterweight box 2 and the impact rod 3 to reciprocate up and down stably and smoothly.

[0025] Furthermore, the lower periphery of the guide rod 8 is provided with an external thread, and the lower periphery of the guide rod 8 is threadedly connected with a limit nut 10. The limit nut 10 serves to limit the height of the counterweight box 2, preventing the counterweight box 2 and the impact rod 3 from breaking the ground too deep, and preventing the counterweight box 2 from being unable to be lifted due to exceeding the lowest lifting position of the cyclic lifting device; at the same time, when the device is not in use, the limit nut 10 can be adjusted upward to support the counterweight box 2, preventing the lower end of the impact rod 3 from contacting the ground, so as to facilitate the transfer of the earth-breaking device.

[0026] In some embodiments, the cyclic lifting device includes a cylinder 11 and a motor 12. The cylinder 11 is laterally rotatably connected to the top of the base 1 and driven by the motor 12. At least one lifting plate 13 is provided on the outer periphery of the cylinder 11. The length direction of the lifting plate 13 is the same as the length direction of the cylinder 11. Force plates 14 are respectively provided on the front and rear sides of the counterweight box 2. The cylinder 11 drives the lifting plate 13 to rotate from bottom to top to the side close to the counterweight box 2, and the lifting plate 13 is against the bottom of the force plate 14. During operation, the motor 12 drives the cylinder 11 to rotate, and the cylinder 11 drives the lifting plate 13 to rotate from bottom to top to the side close to the counterweight box 2, and the lifting plate 13 gradually contacts the bottom of the force-bearing plate 14, thereby lifting the counterweight box 2. When the lifting plate 13 moves upward to a position separated from the force-bearing plate 14, the counterweight box 2 drives the impact rod 3 downward to impact and break the ground under the action of gravity, and the lifting plate 13 continues to rotate to the bottom of the force-bearing plate 14, and the cycle is repeated to realize the function of repeatedly lifting and releasing the counterweight box 2, thereby impacting and breaking the ground.

[0027] In some embodiments, the outer wall of the counterweight box 2 is provided with a liquid level display tube 15 connected to the bottom of the counterweight box 2. The liquid level display tube 15 is convenient for the staff to observe and adjust the water injection amount in the counterweight box 2.

[0028] In some embodiments, a push handle 16 is provided on the rear side of the base 1. The push handle 16 facilitates the staff to push the earth-breaking device to move.

[0029] In some embodiments, the feed port 6 is disposed above the counterweight box 2, and the discharge port 7 is disposed at the bottom of the side of the counterweight box 2. This structural design facilitates the staff to inject water into the counterweight box 2, and also facilitates the complete discharge of water in the counterweight box 2, thereby reducing the overall weight of the earth-breaking device and facilitating transfer or transportation.
