Description

Technical Field

[0001] This utility model relates to the field of pile hole construction technology, specifically to an adjustable mixer. Background Technology

[0002] During the construction of pile holes, the complex underlying environment, particularly in special sites where the bottom of the pile hole is a layer of quicksand, makes drilling difficult. Current solutions primarily involve chemical reinforcement, which involves injecting chemical grout into the quicksand layer using drilling or high-pressure jetting. The grout mix ratio and injection volume are determined based on the properties of the quicksand layer and the reinforcement requirements. However, this method requires careful control of injection pressure and speed to prevent grout from overflowing onto the ground or impacting the surrounding environment, making it technically challenging and costly. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable mixer that can pass through the pile hole and enlarge the bottom of the pile hole, thus providing conditions for subsequent pile bottom construction. It solves the problems of difficult hole formation in quicksand layers, easy hole collapse, and large amount of sediment at the bottom of the hole. The mixer has a simple and compact structure and is easy to operate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable stirrer includes a bottom support, a drive rod detachably mounted above the bottom support, an adjusting rod slidably mounted inside the drive rod, an adapter fixedly mounted at the bottom of the adjusting rod, multiple support rods hinged to the side wall of the adapter, and multiple stirring rods hinged to the side wall of the bottom support. One end of each support rod is movably connected to a corresponding stirring rod. When the adjusting rod is pulled upward, the multiple stirring rods are spread out into an umbrella shape via the support rods; when the adjusting rod is pushed downward, the multiple stirring rods are retracted via the support rods.

[0006] Preferably, a tapered insertion portion is provided at the bottom of the adapter.

[0007] Preferably, one end of the support rod is hinged to the stirring rod at the corresponding position via a pin.

[0008] Preferably, an upper limit switch and a lower limit switch are provided at the top of the adjusting rod, and a scale line is provided on the adjusting rod between the upper limit switch and the lower limit switch.

[0009] Preferably, the end of the support rod is provided with a U-shaped connecting part, and the stirring rod is installed in the U-shaped connecting part.

[0010] Preferably, the top of the adapter is slidably mounted within the bottom support.

[0011] In this invention, by controlling the raising and lowering of the adjusting rod, multiple mixing rods can be spread out to form an umbrella-shaped structure. Driven by the drive rod, the quicksand layer is stirred. Combined with manually added dry-mixed cement and aggregate, an enlarged head pile end bearing layer is reconstructed at the pile bottom, solving the problems of difficult drilling, easy hole collapse, and large amount of sediment at the bottom of the hole in quicksand layers. The conical insertion part facilitates the overall insertion into the quicksand layer. The upper and lower limiters limit the extreme positions of the mixing rods to avoid excessive force. The scale lines allow the operator to control the angle of the mixing rods, enabling precise control of the mixing range. The top of the adapter is slidably installed in the bottom support, so the adjusting rod does not bear the force transmitted by the support rod during the mixing process, ensuring the structural stability of the overall structure during operation.

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figure 1 , Figure 2 and Figure 3 An adjustable mixer, as shown, includes a bottom support 1, a drive rod 2 detachably mounted above the bottom support 1, an adjusting rod 3 slidably mounted within the drive rod 2, an adapter 4 fixedly mounted at the bottom of the adjusting rod 3, multiple support rods 5 hinged to the side wall of the adapter 4, and multiple mixing rods 6 hinged to the side wall of the bottom support 1. One end of each support rod 5 is movably connected to a corresponding mixing rod 6. When the adjusting rod 3 is pulled upwards, the multiple mixing rods 6 are spread out into an umbrella shape via the support rods 5, and the drive rod 2 is rotated by a motor or other rotating device, causing the mixing rods 6 to perform mixing operations. When the adjusting rod 3 is pushed downwards, the multiple mixing rods 6 are retracted via the support rods 5. In this state, the mixer can be inserted into quicksand layers and penetrate into and out of pile holes without damaging the pile holes.

[0018] A tapered insertion part 7 is provided at the bottom of the adapter 4. The tapered insertion part 7 facilitates the insertion of the device into the quicksand layer and reduces the insertion resistance. The top of the adapter 4 is slidably installed inside the bottom support 1. When stirring is performed, the resistance of the stirring rod 6 during the stirring process is transmitted to the support rod 5 and finally to the bottom support 1, avoiding the problem of damage caused by the adjusting rod 3 bearing the force.

[0019] One end of the support rod 5 is hinged to the corresponding stirring rod 6 via a pin. Multiple hinge holes are provided on the stirring rod 6. By connecting the support rod 5 to hinge holes at different positions, different opening angles can be adjusted. Stirring rods 6 of different lengths can be replaced according to the different diameters of the pile holes.

[0020] An upper limit device 8 and a lower limit device 9 are provided at the top of the adjusting rod 3. A scale line 10 is provided on the adjusting rod 3 between the upper limit device 8 and the lower limit device 9. The operator can accurately understand the opening angle of the stirring rod 6 according to the different scale lines 10. The upper limit device 8 and the lower limit device 9 can limit the two extreme positions of the stirring rod 6 to avoid excessive force and damage.

[0021] A U-shaped connecting part 11 is fixedly provided at the end of the support rod 5. The stirring rod 6 is hinged in the U-shaped connecting part 11 by a pin. The U-shaped connecting part 11 can stably support the stirring rod 6 and improve the stability of the stirring operation.

[0022] Multiple sliding bearings are installed inside the drive rod 2, and the adjusting rod 3 is slidably installed inside the sliding bearings.

[0023] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
