Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a mixing device for lime-soil compaction piles. Background Art

[0002] Compaction piles are made by pressing or driving a steel pipe with a pipe plug, valve or cone head into the underground compacted soil layer to form a hole, and then putting ash, sand and gravel and other filling materials into the hole. The ash, sand and gravel need to be stirred and mixed before being put into the ground.

[0003] Among them, the announcement number CN217992969U discloses a mixing device for lime-soil compaction piles, including a mixing box and a water tank, the top of the mixing box is provided with a through opening, and a fixed plate is installed on the top of one end of the mixing box, a top plate is installed on the top of the fixed plate, and a sliding assembly is installed on the bottom of the top plate, an L-shaped plate is slidably installed on the bottom of the sliding assembly, and a second motor is installed on the top of the L-shaped plate, and a second stirring shaft is installed on the output end of the second motor. The utility model is equipped with a push-pull rod, a rotating disk, a bearing, a fixed rod, a rotating shaft and a third motor. When in use, the third motor drives the rotating disk to rotate at a uniform speed through the rotating shaft, so that the push-pull rod can repeatedly push and pull the L-shaped plate to move, and the second stirring shaft and the stirring rod can be moved to different positions inside the mixing box for stirring, and there is no easy stirring dead angle, so that the raw materials can be mixed evenly.

[0004] During use of the device, the second stirring shaft drives the stirring rod to rotate and stir inside the mixing box while moving left and right. Although there is no dead angle for stirring and the amount of ash and soil mixing is increased, in actual use, when the second stirring shaft moves to the left, the ash and soil on the right will be in a stationary state, and when the second stirring shaft moves to the right, the dust on the left will be in a stationary state, and the ash and soil cannot be stirred as a whole, which will cause the mixing degree of the ash and soil on the left and right sides to be different, resulting in a low ash and soil mixing effect, and a long time is required for stirring, and the mixing efficiency is low.

[0005] Therefore, it is necessary to invent a mixing device for lime-soil compaction piles to solve the above problems. Utility Model Content
