This embodiment further includes a base 1 , and the motor 42 and the collection bin 2 are mounted on the base 1 .

[0026] The working principle of this embodiment:

[0027] In this solution, a centrifugal turntable 3 and a crushing structure are arranged in the crushing chamber 22, so that the crushing chamber 22 is divided into a crushing chamber 221 and a sewage discharge chamber 222 by the centrifugal turntable 3 and the crushing structure. The crushing chamber 221 is connected to the collection channel 23, and the sewage discharge chamber 222 is connected to the sewage discharge port 223. The crushing chamber 221 and the sewage discharge chamber 222 are connected through a crushing gap. When in use, after the external conveying mechanism delivers the sand block from the port of the collection bin 2 to the collection chamber 21, the water supply mechanism starts to inject water into the collection chamber 21, and the driving mechanism 4 drives the centrifugal turntable 3 to rotate. Under the driving action of the centrifugal turntable 3, the sand block is pushed onto the crushing structure. Under the mutual cooperation of the centrifugal turntable 3 and the crushing structure, the sand block is crushed. Since the sand block can only enter the sewage discharge chamber 222 from the crushing chamber 221 through the crushing gap, it is ensured that the sand block can enter the sewage discharge chamber 222 and be discharged through the sewage discharge port 223 after being fully crushed, so that the sand block processing module has a good crushing effect.

[0028] like Figure 3 and Figure 4As shown, the crushing structure includes three rows of toothed cutters 24, which are arranged in sequence along the radial direction of the channel opening of the collecting channel 23; each row of toothed cutters 24 includes a connecting portion and a sawtooth segment, the connecting portion is an annular structure arranged around the channel opening of the collecting channel 23, and the sawtooth segment of each row of toothed cutters 24 is arranged on the side of the connecting portion facing the centrifugal turntable 3 along the walking path of the connecting portion. Between each two adjacent rows of toothed cutters 24: the connecting portion of the row of toothed cutters 24 far from the channel opening of the collecting channel 23 is higher than the connecting portion of the row of toothed cutters 24 close to the channel opening of the collecting channel 23, so that the distance between the crushing gaps along the radial direction of the channel opening of the collecting channel 23 is smaller. With such a structure, the sand blocks can be crushed more fully, improving the crushing effect.

[0029] like Figures 3 to 5 As shown, a concave structure 31 with a low center and high surroundings is formed on the top surface of the centrifugal turntable 3, and the crushing gap is formed between the position near the surrounding edges of the concave structure 31 and the crushing structure. A boss portion 32 is formed at the center of the concave structure 31, and a plurality of extension portions 33 are formed on the circumferential surface of the boss portion 32. The plurality of extension portions 33 are arranged around the central axis of the boss portion 32, and each extension portion 33 is connected to the concave structure 31 and extends in the radial direction of the concave structure 31 in the direction away from the boss portion 32. Such a structure can improve the stirring effect of the centrifugal turntable 3, and can better push the sand blocks to move toward the crushing structure.

[0030] like Figures 3 to 5 As shown, four groups of crushing knife groups are formed on the concave structure 31, and the four groups of crushing knife groups are arranged around the central axis of the concave structure 31, wherein two groups of crushing knife groups include two crushing knives 34 arranged in sequence along the radial direction of the concave structure 31, and the other two groups of crushing knife groups include three crushing knives 34 arranged in sequence along the radial direction of the concave structure 31. With such a structure, the sand block can be preliminarily crushed by the crushing knife group before being pushed to the crushing structure, so that the sand block can be crushed more fully and the crushing effect is improved.

[0031] like Figures 3 to 5 As shown, a plurality of blades are formed on the edges of the centrifugal turntable 3, and the blades are arranged around the rotation axis of the centrifugal turntable 3. On the one hand, the blades can further crush the sand blocks entering the sewage discharge chamber 222, so that the sand blocks are crushed more fully; on the other hand, the blades can also play a stirring role, so that the crushed sand blocks can be fully mixed with the water to form mortar.

[0032] like Figure 3 and Figure 4As shown, a mounting hole is formed on the bottom surface of the pulverizing chamber 22, and a clamping hole 36 connected to the bottom surface of the centrifugal turntable 3 is formed on the top surface of the boss portion 32 of the centrifugal turntable 3; the driving mechanism 4 includes a driving shaft 41 and a motor 42; the driving shaft 41 is sequentially formed with a mounting portion 411, a clamping portion 412 and a stirring portion 413 along its axis, the mounting portion 411 and the stirring portion 413 are connected through the clamping portion 412, and one end of the stirring portion 413 passes through the mounting hole, the clamping hole 36 and the collection channel from the bottom surface of the collecting bin 2 in sequence. 23 is arranged in the collecting chamber 21, the mounting portion 411 passes through the mounting hole, and the clamping portion 412 is coaxially fixedly connected with the clamping hole 36, so that the driving shaft 41 can drive the centrifugal turntable 3 to rotate by rotating; a synchronous wheel 43 is coaxially fixedly installed on the driving shaft 41, and the synchronous wheel 43 is located below the crushing chamber 22, and a driving wheel 44 is coaxially fixedly installed on the output shaft of the motor 42, and a synchronous belt 45 is wound between the synchronous wheel 43 and the driving wheel 44, so that the motor 42 can drive the driving shaft 41 to rotate. In this embodiment, a sealing boss 25 is formed on the bottom surface of the crushing chamber 22, and a sealing groove is formed on the end surface of the sealing boss 25, and the mounting hole is connected with the bottom of the sealing groove; it also includes a sealing ring 6, which is sleeved on the mounting portion 411 of the driving shaft 41 and is located in the sealing groove, so as to prevent the water in the sewage discharge chamber 222 from flowing out of the mounting hole. In addition, a positioning boss 11 is formed on the base 1 , and a positioning groove is formed on the end surface of the positioning boss 11 , and one end of the mounting portion 411 of the driving shaft 41 can be rotatably embedded in the positioning groove for positioning.

[0033] like Figure 3 and Figure 4 As shown, an extrusion slope 414 is formed on the circumferential surface of the stirring portion 413, and the extrusion slope 414 is inclined inward along the axial direction of the stirring portion 413 as it approaches the clamping portion 412. With such a structure, the driving shaft 41 can push the sand block to move downward when rotating, ensuring that the sand block is in full contact with the centrifugal turntable 3, which is beneficial for the centrifugal turntable 3 to drive the sand block to move, and improve the crushing effect of the crushing knife group and the crushing structure.

[0034] like Figures 1 to 4As shown, a flow guide structure 211 is formed on the inner wall of the collecting chamber 21, and the travel path of the flow guide structure 211 is a spiral structure arranged around the axis of the collecting chamber 21. A water inlet 212 connected to the outer surface of the collecting bin 2 is formed on the wall of the flow guide structure 211; the water supply mechanism is connected to the water inlet of the collecting bin 2. The water supply mechanism includes a water inlet solenoid valve 5, one end of which is connected to the water inlet 212 of the collecting bin 2 through a pipeline, and the other end of the water inlet solenoid valve 5 is connected to an external tap water pipeline. The collecting chamber 21 can be filled with water by controlling the water inlet solenoid valve 5. Through such a structure, the water entering the collecting chamber 21 can flow and flush along the wall of the collecting chamber 21 to prevent sand block residues from remaining on the wall of the collecting chamber 21, ensuring that the collecting bin 2 remains clean and tidy, and is more convenient to clean.
