[0002] The application of fluidized solidified soil is becoming increasingly widespread, but the equipment used to produce this material is relatively simple. The commonly used mixing mechanisms are largely similar, with only one type of mixing mechanism installed inside the equipment. They all involve adding a certain proportion of solidifying agent and water to the soil, mixing it thoroughly through the mixing structure to form a material with a certain degree of fluidity, and then flowing to the construction site through the discharge port. This has the following problems:

[0003] 1. Larger clay lumps or stones cannot be crushed in the mixing equipment, and the mixing mechanism is easily damaged, shortening the service life of the equipment;

[0004] 2. Clay lumps or stones are difficult to discharge and tend to accumulate at the bottom, clogging the discharge port and affecting the normal operation of the equipment, requiring frequent cleaning;

[0005] 3. The internal space of the mixing equipment is small, and the removal of soil or stones requires operators to enter the mixing equipment, which poses a safety hazard. At the same time, the cleaning is difficult, resulting in reduced production efficiency and increased maintenance costs. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fluid soil mixer with a simple structure and easy cleaning.

[0007] To solve the above problems, the technical solution of this utility model is as follows:

[0008] A fluid soil mixer, comprising:

[0009] The mixing tank has a discharge port on one side of the bottom end and a waste discharge port on the other side of the bottom end. A horizontally arranged mixing shaft is rotatably installed inside. The mixing shaft is driven by a drive motor, and a spiral mixing bar assembly is coaxially fixedly installed on the mixing shaft.

[0010] The cleaning box is a box structure with an opening on the side. The cleaning box is fixed at the waste discharge port of the mixing box, and the interior of the cleaning box is connected to the interior of the mixing box.

[0011] The sealing groove is movable up and down inside the cleaning box, and the shape of the sealing groove corresponds to the shape of the debris discharge outlet.

[0012] The lifting device is located below the cleaning box. The output shaft of the lifting device passes through the bottom end of the cleaning box and is fixed on the sealing groove, which is suitable for driving the sealing groove to move up and down.

[0013] When the drive motor drives the mixing shaft to rotate forward, the sealing groove moves upward and seals the discharge outlet of the debris, which is suitable for mixing fluid soil.

[0014] When the drive motor drives the stirring shaft to reverse, the sealing groove moves downward to the bottom of the cleaning box, the debris discharge port opens, and the stirring bar assembly drives the debris to move to the debris discharge port and discharge it into the cleaning box.

[0015] In a further embodiment, the stirring bar assembly includes a large stirring bar and a small stirring bar, wherein the diameter of the large stirring bar is larger than that of the small stirring bar.

[0016] In a further embodiment, the large stirring bar and the small stirring bar have opposite spiral directions.

[0017] In a further embodiment, a groove cover is hinged to the bottom end of the side of the mixing tank, and the groove cover blocks the side opening of the cleaning tank.

[0018] In a further embodiment, a door stop is threaded onto the bottom end of the cleaning box, and the door stop is located at the side opening of the cleaning box;

[0019] The door stop is located on the outside of the groove cover. When tightening the door stop, the groove cover will be pressed against the cleaning box.

[0020] In a further embodiment, the height of the sealing groove is less than the height of the cleaning box.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] 1. This mixer has a simple structure and is easy to install. A waste discharge outlet is located at the bottom of the mixing tank, and a cleaning box is installed at the outlet. Inside the cleaning box is a liftable sealing groove. During mixing, the sealing groove is pushed upwards to seal the waste discharge outlet, ensuring normal mixing. After mixing, when discharging the waste, the sealing groove is lowered, and the mixing shaft is reversed. This causes the large mixing bars of the shaft to push the waste to the waste discharge outlet, where it falls into the sealing groove and cleaning box. The waste can be cleaned by opening the side cover of the cleaning box, eliminating the need for personnel to enter the mixing equipment. This allows for convenient and quick removal of large clay blocks or stones from the mixing tank, reducing wear and tear or mechanical failures during production, extending the equipment's lifespan, and improving safety while significantly increasing production efficiency and reducing maintenance costs.

[0038] Example 1:

[0039] A type of fluid soil mixer, such as Figures 1 to 5As shown, the mixer body includes a mixing tank 1, a top frame 8, and a bottom frame 9. The bottom ends of several support rods are fixedly installed at intervals on the top part of the bottom frame 9. The top ends of the support rods are all fixedly installed on the bottom end of the top frame 8, which is suitable for connecting the top frame 8 and the bottom frame 9 into a whole. The mixing tank 1 is installed at the bottom end of the top frame 8, and is located between the top frame 8 and the bottom frame 9. The mixing tank 1 has a horizontally rotating mixing shaft 10 installed inside the mixing tank 1. The length of the mixing shaft 10 corresponds to the width of the mixing tank 1. A spiral-shaped large mixing bar 101 and a small mixing bar 102 are fixedly installed around the mixing shaft 10. Several connecting rods are fixedly installed at intervals between the large mixing bar 101 and the mixing shaft 10, and between the small mixing bar 102 and the mixing shaft 10, to connect the mixing shaft 10, the large mixing bar 101 and the small mixing bar 102 into a whole. The diameter of the large mixing bar 101 is larger than that of the small mixing bar 102. The large mixing bar 101 and the small mixing bar 102 rotate in opposite directions, which is suitable for uniformly mixing fluid soil. The bottom end face of the mixing tank 1 has an arc-shaped structure. The diameter of the large mixing bar 101 corresponds to the diameter of the bottom end face of the mixing tank 1, which is suitable for pushing the material to move when the mixing shaft 10 reverses. A motor mount is fixedly installed on the side end of the top frame 8, and a drive motor 81 is fixedly installed on the motor mount. The output shaft of the drive motor 81 is connected to one end of the mixing shaft 10 via a conveyor belt. By rotating the drive motor 81 forward or backward, the mixing shaft 10 is driven to rotate forward or backward, thereby mixing the fluidized soil or discharging impurities. Preferably, a rotating shaft can be fixedly installed on the side of the top frame 8 away from the drive motor 81. A gear is rotatably installed on the rotating shaft, and the gear is connected to the other end of the mixing shaft 10 via a conveyor belt, which is suitable for support.

[0040] like Figures 1 to 3 As shown, a discharge port 7 is provided on one side of the bottom of the mixing tank 1. Various devices such as pipes or collection tanks can be installed at the discharge port 7 to output or collect the mixed fluid soil. In this embodiment, a vertically installed pipe is fixed at the discharge port 7, and the end of the pipe is inclined outward to facilitate the output of fluid soil. A debris discharge port 11 is provided on the other side of the bottom of the mixing tank 1. When the drive motor 81 rotates forward, it drives the mixing shaft 10 to rotate forward, and the mixed fluid soil moves towards the discharge port 7 and is discharged from the discharge port 7. When the drive motor 81 rotates in reverse, it drives the mixing shaft 10 to rotate in reverse, and the debris is pushed by the large mixing bar 101 of the mixing shaft 10 to move towards the debris discharge port 11 and is discharged from the debris discharge port 11.

[0041] like Figures 1 to 3As shown; a cleaning box 2 is provided at the bottom of the mixing tank 1, corresponding to the position of the waste discharge outlet 11. The top of the cleaning box 2 is fixedly connected to the bottom of the mixing tank 1. The cleaning box 2 is a cuboid structure with openings on both sides, including a top opening at the top of the cleaning box 2 and a side opening on the side of the cleaning box 2 near the trough cover 5. The top edge of the cleaning box 2 is tightly fitted to the bottom of the mixing tank 1. The height of the cleaning box 2 is greater than or equal to the height of the waste discharge outlet 11, and the width of the cleaning box 2 is equal to the width of the waste discharge outlet 11. A trough cover 5 is provided on the outer wall of the mixing tank 1 away from the discharge outlet 7, corresponding to the position of the waste discharge outlet 11. The top of the trough cover 5 is hinged to the outer wall of the mixing tank 1 by a hinge, the bottom of the trough cover 5 is a free end, and the width of the trough cover 5 is equal to the width of the side opening of the cleaning box 2. The height of the trough cover 5 is greater than the height of the side opening of the cleaning box 2. When the trough cover 5 hangs down naturally, the bottom of the trough cover 5 is flush with the top of the bottom plate of the cleaning box 2. The bottom plate of the cleaning box 2 has a threaded hole on the side near the trough cover 5. A door stop 6 is threaded into the threaded hole. The door stop 6 is located on the outside of the trough cover 5. When the door stop 6 is tightened, the door stop 6 pushes against the trough cover 5 inward, so that the trough cover 5 can completely seal the side opening and keep the inside of the cleaning box 2 in a closed state.

[0042] like Figure 3 , Figure 4 As shown, a sealing groove 3 is placed inside the cleaning box 2, and a through hole 21 is provided in the middle of the bottom plate of the cleaning box 2; a lifting device 4 is fixed on the top of the base frame 9, corresponding to the position below the cleaning box 2; the output rod of the lifting device 4 passes through the through hole 21 and is fixed to the bottom of the sealing groove 3, so as to realize the up and down movement of the sealing groove 3 along the inner cavity of the cleaning box 2. The top edges of the cleaning box 2 and the sealing groove 3 are set according to the bottom shape of the mixing box 1 to ensure that the top edges of the cleaning box 2 and the sealing groove 3 can fit tightly with the bottom of the mixing box 1 during use, ensuring its sealing performance during operation. The cross-sectional dimensions of the sealing groove 3 correspond to the cross-sectional dimensions of the inner cavity of the cleaning box 2, that is, there is a small gap between the sealing groove 3 and the inner cavity of the cleaning box 2, ensuring that the sealing groove 3 can move smoothly up and down in the cleaning box 2 and preventing debris from falling into the cleaning box 2 during discharge. The height of the sealing groove 3 is less than the height of the cleaning box 2, which better realizes the up and down movement of the sealing groove 3 in the cleaning box 2. To ensure the structural stability of the sealing groove 3, several side supports 31 are spaced apart on the outer wall of the sealing groove 3. The side supports 31 can be triangular, columnar, or planar structures, or made of materials with strength higher than that of the sealing groove 3, which is suitable for strengthening the structure of the sealing groove 3. Preferably, the lifting device 4 is a hydraulic device, such as an oil cylinder or a pneumatic cylinder, which has a lifting function; a rubber strip is fixed to the periphery of the top part of the sealing groove 3, which is suitable for better sealing of the debris discharge port 11.

[0043] The working principle of this utility model is as follows: When the mixer is in working condition, the sealing groove 3 is raised from the bottom of the cleaning box 2 to the top of the cleaning box 2 by the lifting device 4 until the top edge of the sealing groove 3 is tightly attached to the bottom of the mixing box 1. The door stop 6 is tightened to clamp the groove cover 5 to the side wall edge of the cleaning box 2. At this time, the mixing box 1 is in a closed state and can produce and mix fluid soil normally.

[0044] When the mixer needs to discharge material, the mixing shaft 10 is rotated in the reverse direction. The large mixing bar 101 of the mixing shaft 10 pushes the large clay blocks or stones that cannot be crushed to the waste discharge outlet 11. Then, the sealing groove 3 is lowered from the top of the cleaning box 2 to the bottom of the cleaning box 2 through the lifting device 4. At this time, the sealing groove 3 is separated from the bottom of the mixing box 1, and the large clay blocks or stones fall from the waste discharge outlet 11 into the sealing groove 3. Loosen the door stop 6 and open the groove cover 5. The waste can be removed from the sealing groove 3 through the side opening of the cleaning box 2 to complete the cleaning work.

[0045] This utility model has a simple structure and is easy to install. By adding a liftable sealing groove 3 to the bottom of the mixing tank 1, and combining it with the cleaning box 2 to limit the sealing groove 3, large clay blocks or stones in the mixing tank 1 can be easily and quickly cleaned out without the need for staff to enter the mixing equipment for cleaning. This reduces the wear and tear or mechanical failures of the mixing equipment during production, making it safer and greatly improving production efficiency and reducing maintenance costs.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
