Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0038] See also Figure 1-Figure 5 In an embodiment of the present invention, a dual-chamber mud preparation device with built-in stirring includes a frame 1 and a pulping mechanism 3 installed on the frame 1, the pulping mechanism 3 includes an outer shell, a stirring member and a filter member, wherein: the inner side of the outer shell is divided into a filter tank 3052 and a mixing tank 3053 by a partition 317, and the side ends of the filter tank 3052 and the mixing tank 3053 are both provided with a slurry discharge pipe; the stirring member includes a stirring unit rotatably installed in the mixing tank 3053, and a plurality of buckets 315 are fixed to one end of the stirring unit facing the filter tank 3052, and the buckets 315 can rotate with the stirring unit to shovel impurities in the mixing tank 3053 into the filter tank 3052; the filter member includes a conical filter cartridge 310 rotatably installed in the filter tank 3052, and the conical filter cartridge 310 is used to receive impurities shoveled by the bucket 315 and filter the entrained slurry.

[0039] See also Figure 6 and Figure 7 The side end of the frame 1 is also provided with a lifting and loading mechanism 4 for transporting soil into the pulping mechanism 3, and the lifting and loading mechanism 4 is provided with a folding feeding hopper 5 for adding soil to the inside of the lifting and loading mechanism 4, and the outer shell is provided with a feeding port 307 that can be docked with the lifting and loading mechanism 4.

[0040] In this embodiment, water is introduced into the mixing tank 3053, and soil is transported into the mixing tank 3053 through the lifting and loading mechanism 4. The water and soil are fully stirred and mixed by the provided stirring unit to improve the mud preparation effect. At the same time, the provided bucket 315 can rotate with the stirring unit to intermittently shovel the impurities in the mixing tank 3053 into the conical filter cartridge 310 and finally discharge them. At the same time, when the conical filter cartridge 310 rotates, the slurry shoveled by the bucket 315 can be filtered out to reduce the waste of mud.

[0041] To sum up, the pulping equipment provided by the utility model can automatically and effectively filter the impurities in the soil, ensure the high cleanliness of the prepared mud, reduce the content of particulate impurities in the mud to a certain extent, and at the same time filter the impurities through the filter element before discharging them, and filter out the excess mud shoveled in for utilization, effectively reducing the waste of mud and meeting environmental protection requirements.

[0042] The above-mentioned outer shell includes a lower shell 305 fixed on the frame 1 and an upper shell 301 that can be detachably connected to the lower shell 305. After the upper shell 301 and the lower shell 305 are installed, a horizontal cylindrical structure is formed, and the two ends of the cylindrical structure are sealed. The upper shell 301 and the lower shell 305 are detachably connected to facilitate the installation and maintenance of the stirring element and the filter element.

[0043] It should also be noted that in order to facilitate the movement of the device, wheels 2 are installed at the bottom of the frame 1, and brakes are provided on the wheels 2 to ensure the stability of the dual-chamber mud preparation device with built-in stirring during use.

[0044] Further, see Figure 3-Figure 5 , the stirring unit includes:

[0045] The first drive shaft 309 is rotatably mounted in the mixing tank 3053 , and one end of the first drive shaft 309 protruding from the mixing tank 3053 is connected to a first drive source mounted outside the outer shell;

[0046] A plurality of stirring rods 313 are arranged along the circumference of the first driving shaft 309 . The stirring rods 313 are fixed to the first driving shaft 309 via a second connecting frame 319 . The bucket 315 is fixed to one end of the stirring rod 313 facing the filter tank 3052 .

[0047] Exemplarily, in one embodiment, the first driving source includes a second motor 306 mounted on the vehicle frame 1 , and the output shaft of the second motor 306 is rotationally connected to the first driving shaft 309 via a second transmission belt 308 .

[0048] The first drive shaft 309 is driven to rotate continuously by the second motor 306. When the first drive shaft 309 rotates continuously, it drives multiple stirring rods 313 and buckets 315 to rotate. The stirring rods 313 fully mix the water and soil in the mixing tank 3053 to achieve uniformity of the mud. The bucket 315 shovels the impurities at the bottom of the mixing tank 3053, and when the current bucket 315 rotates to the highest point (or close to the highest point), the mud and impurities in the bucket 315 fall out under the action of gravity, thereby achieving the discharge of impurities.

[0049] Preferably, a plurality of inclined material-discharging plates 314 are fixed on the stirring rod 313, which are used to push the slurry and impurities in the mixing tank 3053 toward the filter tank 3052 when the stirring rod 313 rotates, thereby transporting the impurities in the mixing tank 3053 toward one side of the partition 317, so that the bucket 315 can scoop them up when it moves to the bottom of the mixing tank 3053.

[0050] In order to facilitate the entry of impurities into the conical filter cartridge 310 , an inclined guide plate 316 for receiving impurities conveyed by the bucket 315 and conveying the impurities toward the conical filter cartridge 310 is fixed to the partition plate 317 .

[0051] Further, see Figures 1-4 A second drive shaft 311 is coaxially arranged on the inner side of the conical filter cartridge 310. The second drive shaft 311 is fixed to the conical filter cartridge 310 through multiple first connecting frames 318. The second drive shaft 311 is driven to rotate by a second drive source installed on the outer shell.

[0052] Exemplarily, in one embodiment, the second driving source includes a first motor 302 mounted on the upper shell 301, and the output shaft of the first motor 302 is rotatably connected to the second driving shaft 311 through a first transmission belt 303. The first motor 302 drives the first driving shaft 311 to rotate through the first transmission belt 303, and the first driving shaft 311 drives the conical filter cartridge 310 to rotate to filter impurities so that the mud shoveled in is discharged through the slurry discharge pipe.

[0053] Furthermore, a through groove 3051 for discharging impurities in the conical filter cartridge 310 is formed at the end of the outer shell, and a slag discharge plate 304 is fixed to the outer shell on the side of the through groove 3051 facing the ground. A spiral blade 312 is installed on the inner side of the conical filter cartridge 310, and the spiral blade 312 rotates with the conical filter cartridge 310 to transport the impurities in the conical filter cartridge 310 to one end of the conical filter cartridge 310.

[0054] In this embodiment, when the conical filter cartridge 310 rotates, the spiral blade 312 is driven to rotate, so as to transport the impurities in the conical filter cartridge 310 toward the position of the through groove 3051, and drop them from the through groove 3051 to the slag discharge plate 304, thereby achieving the discharge of impurities.

[0055] Preferably, a drainage groove 3151 is formed on the bucket 315 along one side of the bucket 315 in the direction of rotation of the stirring rod 313. When the bucket 315 scoops up impurities and mud and rotates upward, when the bucket 315 is off the ground, the mud in the bucket 315 can fall back into the mixing tank 3053 through the drainage groove 3151, thereby reducing the amount of mud entering the filter tank 3052 to a certain extent.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
