[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Example: Please see Figure 1-4 This utility model provides a technical solution: A foundation pit cleaning and leveling device includes a bucket 1, bucket teeth 2 and mounting sleeve 3. The bucket teeth 2 are evenly arranged and fixed on the right side of the bucket 1. The mounting sleeve 3 is located outside the bucket teeth 2 and its left side contacts the right side of the bucket 1. A scraper 4 is fixed on the right side of the mounting sleeve 3. The foundation pit can be cleaned by moving the scraper 4. The mounting sleeve 3 is internally connected to a longitudinally rotating lead screw 5. The lower end of the lead screw 5 is rotatably connected to the lower end of the inner wall of the mounting sleeve 3 via a bearing. The upper end of the lead screw 5 is fixed with a rotating block 6. The rod wall of the lead screw 5 is threadedly connected to a lifting plate 7. The right side of the lifting plate 7 is slidably connected to the right end of the inner wall of the mounting sleeve 3. The lower left end of the lifting plate 7 is fixed with a pressing pad 8. The lower side of the lifting plate 7, located at the right end of the pressing pad 8, is fixed with evenly arranged limiting blocks 9. Rotating the rotating block 6 causes the lead screw 5 to rotate, which in turn causes the lifting plate 7, which is threadedly connected to the rod wall, to move downward. The lifting plate 7 causes the pressing pad 8 on the lower side to press against the upper end of the evenly arranged bucket teeth 2, thereby limiting the mounting sleeve 3 to the left and right. The evenly arranged limiting blocks 9 are also engaged between adjacent bucket teeth 2, thereby limiting the mounting sleeve 3 to the front and rear.

[0017] The pressing pad 8 is a rubber layer. The lower side of the pressing pad 8 contacts the upper side of the bucket tooth 2. By increasing the degree of deformation of the rubber layer, the pressing pad 8 is fully attached to the bucket tooth 2, thereby increasing the friction between them.

[0018] The front and rear sides of the limiting block 9 are in contact with the side wall of the bucket tooth 2.

[0019] Adjustment mechanisms are fixed on both the front and rear sides of the mounting sleeve 3. Reinforcing strips 10 are fixed to the opposite ends of the two adjustment mechanisms. The upper end of the reinforcing strip 10 is threaded with a clamping bolt 11. The two clamping bolts 11 are engaged with the front and rear sides of the bucket 1. The distance between the two reinforcing strips 10 can be adjusted by the adjustment mechanism, so that the reinforcing strip 10 can adapt to the front and rear width of the bucket 1. The clamping and pressing between the clamping bolt and the bucket 1 increases the friction, ensuring that the reinforcing strip 10 can better connect the mounting sleeve 3 to the bucket 1.

[0020] The adjustment mechanism includes a limiting tube 12, which is fixedly connected to the front and rear sides of the mounting sleeve 3 respectively. The mounting sleeve 3 has symmetrical adjusting rods 13 slidably connected inside. Both adjusting rods 13 are slidably connected to the limiting tubes 12. The upper sides of both mounting sleeves 3 are threaded with adjusting bolts 14. The lower ends of the two adjusting bolts 14 extend into the interior of the limiting tubes 12 and engage with the adjusting rods 13. The adjusting bolts 14 are fixed by tightening the adjusting rods 13.

[0021] Both the mounting sleeve 3 and the scraper 4 have inclined surfaces on their right sides, which makes it easier for soil to enter the interior of the bucket 1 during the leveling process.

[0022] Working principle: When the pit needs to be leveled using the trench clearing and leveling device, the mounting sleeve 3 is placed on the outside of the evenly arranged bucket teeth 2. The lower end of the inner wall of the mounting sleeve 3 is in contact with the lower side of the bucket teeth 2. By rotating the rotating block 6, the rotating block 6 drives the screw 5 on the side wall to rotate. The screw 5 drives the lifting plate 7 and the pressing pad 8 on the rod wall to move down, clamping and fixing multiple bucket teeth 2. The evenly arranged limiting blocks 9 are locked between adjacent bucket teeth 2. Move the two adjusting rods 13. When the appropriate distance is reached, tighten the adjusting bolts 14 to fix the adjusting rods 13 and the limiting tubes 12. And use the clamping bolts 11 to clamp and fix the other end of the reinforcing strip 10 to the side wall of the bucket 1.
