[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a mud screening device for bored pile production, comprising a steel grating filter 1, the steel grating filter 1 is arranged in a frame assembly 2, the steel grating filter 1 and the frame assembly 2 are both provided with two, the frame assembly 2 comprises two inner ring steel frames 201 and two outer ring steel frames 202, and a plurality of steel bar hooks 203 are distributed in a ring matrix between the two inner ring steel frames 201 and the two outer ring steel frames 202, the two inner ring steel frames 201 are fixedly connected with the two outer ring steel frames 202 and the plurality of steel bar hooks 203, the steel grating filter 1 and the filter cotton 3 are movably placed in the frame assembly 2 in sequence, the steel grating filter 1 and the filter cotton 3 are both in a ring shape, and the plurality of steel bar hooks 203 are hung on the steel casing 5 for use. The setting of the inner steel frame 201 and the outer steel frame 202 can connect a plurality of steel hooks 203, and the setting of a plurality of steel hooks 203 can support the steel grid filter 1 and the filter cotton 3. The steel grid filter 1 and the filter cotton 3 can be confined by the inner steel frame 201, the outer steel frame 202, and the plurality of steel hooks 203. The setting of the steel grid filter 1 and the filter cotton 3 can screen the mud, and the filter cotton 3 can reduce the clogging of the steel grid filter 1.

[0026] Two clamping assemblies 4 for fixing the steel grating filter 1 are arranged on the steel bar hook 203, and the clamping assemblies 4 are slidably connected to the steel bar hook 203. The two clamping assemblies 4 are respectively arranged on both sides of the steel bar hook 203 close to the inner ring steel frame 201 and the outer ring steel frame 202. The clamping assembly 4 includes a moving rod 401 slidably arranged on the steel bar hook 203, and a limiting protrusion limited within the steel bar hook 203 is arranged at one end of the moving rod 401 and the sliding of the steel bar hook 203. A vertical slide groove 204 and an annular slide groove 205 for the moving rod 401 to slide are arranged on the steel bar hook 203, and the vertical slide groove 204 and the annular slide groove 205 are through-connected, and a clamp plate 402 is hingedly arranged at one end of the moving rod 401, and a spring 403 is fixedly arranged between the moving rod 401 and the clamp plate 402. By sliding the moving rod 401 in the vertical slide groove 204 and the annular slide groove 205, the positions of the moving rod 401 and the clamping plate 402 can be adjusted, so that the steel grating filter 1 and the filter cotton 3 can be placed in the frame assembly 2. Through the setting of the spring 403, a pulling force can be applied to the clamping plate 402. Since the moving rod 401 and the clamping plate 402 are hinged to each other, the clamping plate 402 is rotated so that the clamping plate 402 is buckled in the steel grating filter 1.

[0027] The working principle of this utility model:

[0028] When the slurry needs to be screened during the production of cast-in-place piles, the steel grid filter 1 and the screening cotton 3 are first placed in the frame assembly 2 in sequence, and then the moving rod 401 is slid on the annular slide groove 205 and then slides to the vertical slide groove 204. When the clamping plate 402 blocks the steel grid filter 1, the clamping plate 402 can be pulled to deform the spring 403, and then the moving rod 401 is slid downward so that the clamping plate 402 is buckled in the steel grid filter 1, and then the clamping plate 402 is released. The elastic force of the spring 403 can pull the clamping plate 402 so that one side of the steel grid filter 1 is clamped by the clamping plate 402 and the inner ring steel frame 201, and the other side of the steel grid filter 1 is clamped by the clamping plate 402 and the outer ring steel frame 202. Then, a plurality of steel bar hooks 203 can be hung on the steel casing 5, so that the cast-in-place pile can be cast, and the mud has a screening effect when passing through the steel grid filter 1 and the screening cotton 3.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
