[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: This example addresses the shortcomings of existing slurry mixing and conveying systems, such as difficulty in screening impurities or lumps in the slurry, and the tendency for impurities or lumps to clog pipelines during transport, making it difficult to ensure the uniformity and stability of the slurry.

[0024] Please see Figure 1 - Figure 5 As shown, this embodiment is a slurry mixing and conveying mechanism for a water-utilizing cement mixing pile, including a frame 1, which is a rectangular frame. A water tank 2 is fixedly installed inside the frame 1. A control box 3 is fixedly installed on the side of the frame 1 closest to the water tank 2. A mixing mechanism is provided on the side of the frame 1 away from the control box 3. The mixing mechanism includes a storage cylinder 4 and a mixing cylinder 5. External cement raw materials are conveyed into the mixing cylinder 5 through a screw feeder. The mixing cylinder 5 mixes and stirs the slurry raw materials. The mixing cylinder 5 is located at the bottom of the storage cylinder 4. A connection port 9 for a conveying pump is fixedly connected to one side of the bottom wall of the storage cylinder 4. The connection port 9 is connected to the cement mixing pile through the conveying pump and pipeline. An auxiliary mechanism is provided between the storage tank 4 and the mixing tank 5. The auxiliary mechanism includes a filter box 12 located at the bottom discharge port of the mixing tank 5. A valve is provided at the discharge port at the bottom of the mixing tank 5 to control the discharge. A connecting seat 11 is provided directly above the storage tank 4. Two symmetrically arranged mounting plates 16 are fixedly connected to the upper surface of the connecting seat 11. Sliding rods 18 are fixedly connected to both sides of the filter box 12, passing through the mounting plates 16 and slidingly connected to the mounting plates 16 in a horizontal limiting manner. The two mounting plates 16 limit the horizontal movement of the filter box 12, ensuring that the filter box 12 can move stably in the horizontal direction. By reciprocating the movement of the filter box 12, impurities or lumps in the mixing tank 5 are screened and filtered to ensure their uniformity and stability, thereby improving the construction quality. At the same time, it prevents blockages during the conveying process, improves the continuity and stability of the conveying pump, and thus improves the construction efficiency.

[0025] A conveying pump is fixedly installed on one side of the control box 3 and connected to it. A conveying pipe 6 connected to the conveying pump is provided on one side of the control box 3. The conveying pipe 6 extends to the top of the mixing drum 5. The conveying pump is started to convey water from the water tank 2 into the mixing drum 5. A feed inlet is provided on the outer wall of the water tank 2. The feed inlet is connected to the external conveying end for feeding.

[0026] A connecting strip 10 is fixedly connected to the inner side of the frame 1 for the fixed installation of the connecting seat 11. The connecting seat 11 is penetrated and rotatably connected to the stirring shaft 17. A motor 2 is fixedly installed on the connecting seat 11. The output end of the motor 2 is connected to the stirring shaft 17 through a reducer. When the motor 2 is started, it drives the stirring shaft 17 to rotate. The stirring shaft 17 continuously stirs the slurry in the storage tank 4 to prevent the slurry from settling.

[0027] A fixed base 8 is fixedly installed on the upper surface of the frame 1. A stirring shaft 7 is rotatably connected to the lower surface of the fixed base 8. A motor 3 is fixedly installed on the fixed base 8. When the storage tank containing cement raw materials is fed into the mixing drum 5 through the conveying pipe 6, and water is conveyed into the mixing drum 5 through the conveying pipe 6, the motor 3 is started to drive the stirring shaft 7 to rotate, and the water and slurry added into the mixing drum 5 are stirred.

[0028] Example 2: This example addresses how to further improve the continuity and stability of slurry delivery.

[0029] Please see Figure 1 - Figure 5 As shown in this embodiment, a slurry mixing and conveying mechanism for a water-utilizing cement mixing pile has a spring 19 fitted on the outer contour of a sliding rod 18, which abuts against a filter box 12 and a mounting plate 16. A mounting base 13 is fixedly connected to one side of the mounting plate 16, and a cam 20 is rotatably connected to the surface of the mounting base 13. A push plate 15, which is fixedly connected to the sliding rod 18, is provided on one side of the cam 20. A motor is fixedly installed on the outer wall of the mounting base 13. When the motor is started, it drives the cam 20 to rotate. Under the reset action of the spring 19, the cam 20 can be pushed to move the filter box 12 back and forth to screen the slurry containing large particles or clumps.

[0030] The filter box 12 contains a detachable filter plate 14. The surface of the filter plate 14 is provided with evenly distributed filter holes. A handle is fixedly installed on the surface of the filter plate 14. The filter plate 14 can be removed from the filter box 12 by using the handle, which makes it easy to remove large particles or clumps on the filter plate 14.

[0031] Combining Embodiments 1 and 2, by setting up a stirring mechanism and an auxiliary mechanism, the mixing drum 5 and the storage drum 4 are combined. The slurry is stirred in the mixing drum 5 and then transported to the mixing drum 5 for continued stirring to prevent sedimentation. This facilitates the storage and transportation of the slurry after stirring and can effectively screen and filter impurities or lumps in the mixing drum 5, further ensuring the uniformity and stability of the slurry. By setting the cam 20 to rotate and cooperating with the reset action of the spring 19, the reciprocating movement of the filter box 12 is realized, which greatly improves the filtration efficiency and ensures the continuity and stability of screening and filtration, further improving the continuity and stability of the delivery pump.
