The arrangement enables qualified garbage grinding particles after being knocked by the grinding hammer and the convex hull to rapidly flow onto the second grinding device from the water leakage hole.

The garbage enters the operation area of the first grinding disc 41 through the water storage tank 1, and is changed into 4-5mm garbage grinding particles through the combined action of the grinding hammer, the convex hull, the cutting knife, the first grinding disc 41 and the common grinding ring 3 including the upper part of the first grinding hole 31 in the operation area of the first grinding disc 41, along the water leakage hole on the first grinding disc 41 and the first grinding hole 31, the clearance of first abrasive disk 41 and common abrasive ring 3 gets into the operation interval of second abrasive disk 42, through the grinding hammer of the interval of second abrasive disk 42 operation, second abrasive disk 42 and including first grinding hole 31 lower part, the combined action of common abrasive ring 3 including second grinding hole 32, rubbish abrasive particle is ground into 2-3mm granule that the volume is littleer, flows out and is arranged in the sewer along the hole that leaks on the second abrasive disk, second grinding hole 32, second abrasive disk 42 and the clearance of common abrasive ring 3 at last. If the garbage grinding particles are larger than 5mm, the garbage grinding particles are continuously ground in the working interval of the first grinding disk 41, and the garbage grinding particles can not enter the working interval of the second grinding disk 42 until the garbage grinding particles are ground into the garbage grinding particles smaller than or equal to 5mm, and similarly, the garbage grinding particles flowing into the working interval of the second grinding disk 42 can not flow out of the working interval of the second grinding disk 42 to be discharged into a sewer after being ground into the garbage grinding particles smaller than or equal to 2 mm.

In the embodiment of the present invention, a third grinding disc may be further included under the second grinding disc 42, the third grinding disc is fixed on the driving shaft 51, the third grinding disc cooperates with the common grinding ring 3 to further process the ground garbage particles, preferably, the third grinding disc is provided with grinding hammers and water leakage holes, and the grinding hammers on the third grinding disc are the same as those on the second grinding disc 42.

Alternatively, in the embodiment of the present invention, a second grinding ring and a third grinding disc located below the second grinding disc 42 may be further included, the third grinding disc is fixed on the driving shaft 51, the second grinding ring is arranged on the outer periphery of the third grinding disc and is installed on the inner wall of the grinding chamber 2, and the second grinding ring and the third grinding disc cooperate to further process the ground garbage particles.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
