[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-Figure 5As shown, the present embodiment discloses a foundation pit cleaning and leveling device, including a mounting sleeve 1, a receiving groove 101 is provided on one side of the mounting sleeve 1, and a scraper 2 is connected to the other side; there are multiple threaded sleeves 3, and the multiple threaded sleeves 3 are arranged at intervals along the length direction of the receiving groove 101, and the threaded sleeves 3 are staggered with the bucket teeth 7 of the excavator bucket; the connecting bolts 4 are arranged in a one-to-one correspondence with the threaded sleeves 3, and the screw ends of the connecting bolts 4 penetrate into the receiving groove 101 and are threadedly connected with the threaded sleeves 3; there are two clamping plates 5, and the two clamping plates 5 are slidably arranged on both sides of the receiving groove 101; there are two adjusting components 6, and the two adjusting components 6 are respectively arranged on both sides of the mounting sleeve 1, and are respectively connected to the corresponding clamping plates 5.

[0026] In this embodiment, the accommodating groove 101 is used to accommodate the bucket teeth 7 on the excavator bucket, the scraper 2 is fixedly connected to the mounting sleeve 1, and the scraper 2 is used to remove the original soil with a thickness of 200mm-300mm reserved in the foundation pit; a connecting sleeve 102 is fixed on the bottom wall of the accommodating groove 101, and a threaded sleeve 3 is fixed in the connecting sleeve 102, and the threaded sleeve 3 is arranged vertically; the adjustment assembly 6 is used to drive the clamping plate 5 to move in a straight line, so that the clamping plate 5 and the bucket teeth 7 located at the edge are clamped or released from the abutment relationship.

[0027] By adopting this scheme, the threaded sleeve 3, connecting bolts 4, clamping plate 5 and adjustment assembly 6 are provided to facilitate the installation, fixing and disassembly of the installation sleeve 1; the scraper 2 is provided to achieve the effect of mechanical cleaning of the foundation pit without disturbing the original soil, which not only saves manpower, but also improves the efficiency of cleaning and speeds up the construction progress.

[0028] A further optimized solution is that the adjusting assembly 6 includes a horizontally arranged adjusting screw 61, one end of the adjusting screw 61 passes through the clamping plate 5 and is rotatably connected to the mounting plate 62, the mounting plate 62 is fixedly connected to the groove wall of the accommodating groove 101, and the adjusting screw 61 is threadedly connected to the clamping plate 5; the other end of the adjusting screw 61 passes through the outside of the accommodating groove 101, and the adjusting screw 61 is rotatably connected to the mounting sleeve 1.
