The pile foundation construction methods include: hammering method, vibration method, pressing method, and water jetting method. The rotary drilling pile is a commonly used type of pile foundation. It uses a rotary drill bit to drill holes in the soil layer and simultaneously injects mud in a directional manner. While forming the pile hole, it ensures the stability of the hole wall and discharges the soil chips from the hole. Therefore, mud is very important for the construction process of rotary drilling piles. Due to the importance of mud in rotary drilling pile construction, it is necessary to monitor and control the quality of mud to ensure the construction quality. The main purposes of mud detection are: 1. Ensure that the quality of mud meets the design requirements; 2. Grasp the changes in mud process parameters and adjust them in a timely manner; 3. Provide reliable data support for the subsequent pile inspection during construction.

The existing stirring devices cannot separate the solid substances in the mud, which is not convenient for calculating the content of solid substances. Therefore, there is an urgent need in the market to develop a stirring device for mud testing in pile foundation construction to help people solve the existing problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0022] Please refer to Figures 1-4, an embodiment provided by the present utility model: a stirring device for mud testing in pile foundation construction, including a stirring device 1. In the middle of the lower end face inside the stirring device 1, a support pipe 101 is fixedly connected. In the middle of the lower end inside the stirring device 1, a stirring shaft 2 is rotatably connected. On the stirring shaft 2, a plurality of stirring rods 201 are fixedly connected in an annular array. In the middle of the upper end inside the stirring device 1, a separation barrel 3 is connected. On the separation barrel 3, a barrel-shaped filter screen 301 is provided. In the middle of the lower end face of the barrel-shaped filter screen 301, a connecting piece 302 is fixedly connected. In the middle of the inside of the barrel-shaped filter screen 301, a separation shaft 4 is rotatably connected. On the separation shaft 4, a plurality of separation rods 401 are fixedly connected in an annular array. In the middle of the upper end face of the stirring device 1, a first circular socket 104 is provided. The upper end of the separation barrel 3 extends out of the first circular socket 104 and is fixedly connected with an annular support plate 304. In the middle of the annular support plate 304, a second circular socket 305 is provided. The upper end of the second circular socket 305 is connected with a top cover 5.
[0023] Furthermore, in the middle of the lower end of the stirring device 1, a motor box 102 is fixedly connected, and a motor 103 is arranged inside the motor box 102.
[0024] Furthermore, the lower end of the stirring shaft 2 passes through the middle of the support pipe 101 and extends into the motor box 102 to be fixedly connected with the output shaft of the motor 103. The motor 103 drives the stirring shaft 2 to rotate, and then the stirring shaft 2 drives the stirring rods 201 to rotate, so that the stirring rods 201 fully stir the mud entering the inside of the stirring device 1, making the components in the mud evenly distributed, which is convenient for subsequent accurate detection.
[0025] Furthermore, a transmission groove 303 is arranged inside the connecting piece 302. The lower end of the separation shaft 4 passes through the upper end face of the connecting piece 302 and extends into the transmission groove 303 to be fixedly connected with a transmission part 402. In the middle of the lower end face of the transmission part 402, a circular limiting groove 403 is provided. Between the middle parts of both sides of the circular limiting groove 403 and the outer end face of the transmission part 402, rectangular sliding grooves 404 are arranged.
[0026] Furthermore, on both upper ends of the stirring shaft 2, limiting rods 202 are fixedly connected. The upper end of the stirring shaft 2 is inserted into the circular limiting groove 403, and the two limiting rods 202 respectively slide into the two rectangular sliding grooves 404. The stirring shaft 2 drives the connecting piece 302 to rotate inside the transmission groove 303, and then the connecting piece 302 drives the separation shaft 4 to rotate. When the separation shaft 4 rotates, it drives the separation rods 401 to rotate, so that the separation rods 401 disperse and stir the mud inside the separation barrel 3, separating the solid substances from the mud in the mud, which is convenient for subsequent stirring of the mud. The dispersed mud enters the inside of the stirring device 1 through the barrel-shaped filter screen 301, and the barrel-shaped filter screen 301 blocks the solid substances.
[0027] Furthermore, a ring-shaped limiting member 501 is fixedly connected to the lower end of the top cover 5, and a limiting tube 502 is fixedly connected to the middle of the lower end of the top cover 5.
[0028] Furthermore, the ring-shaped limiting member 501 at the lower end of the top cover 5 is inserted into the inner part of the second circular socket 305, and the upper end of the separation shaft 4 is inserted into the middle of the limiting tube 502. The top cover 5 closes the second circular socket 305, and at the same time, the limiting tube 502 ensures the stability of the rotation of the upper end of the separation shaft 4.
[0029] Working principle: During use, the mud material is fed into the separation barrel 3 through the second circular socket 305 and clean water is injected. The ring-shaped limiting member 501 at the lower end of the top cover 5 is inserted into the inner part of the second circular socket 305, and at the same time, the upper end of the separation shaft 4 is inserted into the middle of the limiting tube 502. The motor 103 drives the stirring shaft 2 to rotate. The upper end of the stirring shaft 2 is inserted into the circular limiting groove 403, and the two limiting rods 202 respectively slide into the two rectangular sliding grooves 404. The stirring shaft 2 drives the connecting member 302 to rotate in the transmission groove 303, and then the connecting member 302 drives the separation shaft 4 to rotate. When the separation shaft 4 rotates, it drives the separation rods 401 to rotate, so that the separation rods 401 disperse and stir the mud material in the separation barrel 3, separating the solid substances from the mud slurry in the mud material, which is convenient for the subsequent stirring of the mud slurry. The dispersed mud material enters the stirring device 1 through the barrel-shaped filter screen 301. The barrel-shaped filter screen 301 blocks the solid substances. The stirring shaft 2 drives the stirring rods 201 to rotate, so that the stirring rods 201 fully stir the mud slurry entering the stirring device 1, making the components in the mud slurry evenly distributed, which is convenient for subsequent accurate detection. After the stirring is completed, the separation barrel 3 is lifted out from the first circular socket 104 through the annular support plate 304, and the solid substances blocked inside the barrel-shaped filter screen 301 can be collected, which is convenient for calculating the solid substance content.
