Through setting up first feeding mechanism 421 in feed portion 100, can push away rubbish to grinder 400's body 410, can overcome the poor problem of rubbish mobility, avoid adding water when the feeding, the rubbish input of being convenient for. In addition, set up second feeding mechanism 431 in second end 430, can make the rubbish of grinding for thick liquids in time release grinder 400 for in the grinding process, the rubbish solid content in body 410 is higher, is convenient for grind the slurrying, simultaneously, has improved grinding efficiency.

In this embodiment, the body 410 of the polishing apparatus 400 is a polishing barrel 410a, and the polishing elements 440 in the body 410 can be polishing balls with different diameters. The grinding cylinder 410a has a first end 420 and a second end 430 at its axial ends. Specifically, the first and second end portions 420 and 430 are hollow shafts for connecting with the inlet portion 100 and the outlet portion 200, and the first and second end portions 420 and 430 are connected to the base 450 through the bearing housing 460, respectively, so that the grinding apparatus 400 is fixed to the base 450. The driving device 300 is connected with the grinding device 400, so that the grinding device 400 rotates around the rotation axis thereof under the driving of the driving device 300, and in the rotation process of the grinding device 400, the grinding piece 440 is thrown up and falls down, rolls in the body 410 in a reciprocating manner and makes a parabolic motion, so that the garbage is crushed and extruded, and the solid garbage is made into slurry. Specifically, the driving device 300 may be electrically driven or pneumatically driven, or the like.

The feeding part 100 has a tubular structure, and the feeding hole 110 is provided at an upper side of the feeding part 100 so that the garbage can be transferred into the feeding part 100 from the upper side of the feeding part 100. The feed inlet 110 may also be provided at the left end of the feed part 100. The right end of the feeding portion 100 can be sleeved in the first end portion 420 and extend into the first end portion 420 for a certain distance, and the length of the feeding portion 100 extending into the first end portion 420 can be equal to the axial length of the first end portion 420, so that garbage entering the feeding portion 100 can be directly input into the body 410. A certain gap may exist between the outer circumferential surface of the feeding portion 100 and the inner circumferential surface of the first end portion 420, so as to prevent the first end portion 420 from rubbing against the feeding portion 100 during rotation, and prevent the first end portion 420 and the feeding portion 100 from aging and being damaged due to rubbing. It is contemplated that the feeding portion 100 may also be disposed outside the first end portion 420, so long as waste can be delivered to the grinding apparatus 400. Compared with the above, the feeding portion 100 is sleeved inside the first end portion 420, so that the garbage can be effectively prevented from escaping from the connection position of the feeding portion 100 and the first end portion 420.

The discharging part 200 is a tubular structure, in some embodiments, the discharging part 200 may be an L-shaped tubular structure, one end of the L-shaped discharging part 200 may be sleeved outside the second end 430, and a certain gap is provided between an inner circumferential surface of the discharging part 200 and an outer circumferential surface of the second end 430 to prevent the discharging part 200 and the second end 430 from being worn due to rotation of the grinding device 400; the other end of the discharging part 200 is set as a discharging port 210, the discharging port 210 can be arranged downward, and the ground garbage slurry is discharged quickly by using the gravity of the ground garbage slurry. It is conceivable that the axes of the inlet portion 100 and the outlet portion 200 are all aligned with the rotation axis of the grinding apparatus 400, thereby ensuring that the grinding apparatus 400 can move smoothly without interference between the inlet portion 100 and the outlet portion 200 when rotating.
