As shown in fig. 1 and 2, the low-noise wall breaking machine comprises a main machine 1 with a working chamber 11, a motor assembly 2 arranged in the main machine, a stirring assembly 3 driven by the motor assembly, and a slurry receiving assembly 4 positioned on one side of the main machine, wherein the motor assembly comprises a motor with an output shaft, and the output shaft of the motor is in transmission connection with the stirring assembly. When juice is required to be squeezed and the food materials are crushed into slurry, the stirring assembly can be driven by the motor assembly to rotate at a high speed, so that the wall breaking treatment can be performed on the food materials in the working cavity.

Of course, the upper part of the main machine should be provided with an opening communicated with the working chamber, and the cup 12 should be arranged at the opening.

It should be noted that, as for the wall breaking machine, the main machine, the motor assembly, the stirring assembly, the slurry receiving assembly, and the like all belong to the prior art, and therefore, the basic structure thereof is not described in detail in this embodiment.

It is known that, in current broken wall machine, the motor element usually directly is connected with the stirring subassembly to through output shaft transmission connection, so that make the motor drive the high-speed rotation of stirring subassembly, consequently, the produced vibration of high-speed pivoted motor, stirring subassembly and corresponding vibration noise can direct mutual conduction, increase vibration intensity and noise then.

To this end, we can provide a connecting bracket 5 between the stirring assembly and the motor assembly, the stirring assembly being arranged on the upper side of the connecting bracket and the motor assembly being arranged on the lower side of the connecting bracket.

In addition, a sound insulation retaining ring which extends towards one side and surrounds the motor assembly and/or the stirring assembly can be arranged on the connecting support, so that the vibration noise of the motor assembly and the stirring assembly connected with the connecting support can be effectively blocked, and particularly, the radial transmission of the vibration noise can be effectively avoided. That is, the soundproof collar "meanders" the propagation path of the vibration noise in the radial direction, and thus effectively extends the propagation path of the noise, so that the noise is effectively attenuated.

In particular, the sound insulation retainer ring is only used for blocking the transmission of noise, so that the sound insulation retainer ring does not need to be in direct contact with the stirring assembly and the motor assembly, and the assembly of the stirring assembly and the motor assembly is not influenced.

It will be appreciated that the stirring assembly should include a knife assembly having an arbor and preferably, as shown in fig. 3, the sound isolation collar includes an upper collar 51 extending upwardly from the attachment bracket and surrounding the arbor.

Therefore, when the motor component drives the cutter component to rotate at a high speed, the cutter component, particularly the cutter shaft, can generate strong high-frequency vibration and corresponding vibration noise due to the existence of the connection relation, particularly when the connection part of the motor component and the cutter component has certain deviation and looseness. The upper baffle ring is arranged around the cutter shaft in the cutter assembly, so that the radial transmission of vibration noise generated by the cutter shaft can be effectively isolated, and the sound insulation baffle ring can play the maximum sound insulation effect.

It should be noted that we can properly control the diameter of the upper retainer ring, so that the upper retainer ring is as close to the cutter shaft as possible, so as to surround the vibration noise generated by the cutter shaft within a small range of the right, thereby maximally improving the sound insulation effect of the upper retainer ring, and simultaneously avoiding the unnecessary increase of the size of the whole wall breaking machine due to the connection of the bracket.

The installation sinking platform makes things convenient for the location installation of arbor, when last retaining ring and installation sinking platform overlap in the direction of height part, goes up retaining ring and the snake-shaped of the reciprocal tortuous of installation sinking platform formation in axial cross-section to the route of noise when radial transmission can be further prolonged, and then the effect of effective attenuation noise is reached.

It should be noted that, here, the upper retainer ring and the installation sinking platform are partially overlapped in the height direction, which may mean that they are overlapped with each other, or may be in a mutually separated state with different outer diameters, so as to facilitate the assembly of the stirring assembly on the connecting bracket.

Furthermore, a cutter shaft sealing ring 31 can be arranged between the cutter shaft and the installation sinking platform so as to seal the cutter shaft extending upwards into the working cavity, avoid leakage of slurry, form good elastic buffer matching and connection between the cutter shaft and the heating plate, effectively prevent vibration generated by the cutter shaft driving the cutter assembly to rotate at high speed from being transmitted to the host machine through the heating plate, and be beneficial to vibration reduction and noise reduction of the wall breaking machine.

It should be noted that, the upper retainer ring and the lower retainer ring can be provided with different outer diameters as required, that is, the upper retainer ring and the lower retainer ring divide the whole sound insulation retainer ring into two sections in height, so that the sound insulation retainer ring can be conveniently molded without reducing the height of the whole sound insulation retainer ring and the sound insulation effect.

In order to slow down the vibration conduction between the connecting bracket and the stirring assembly and between the connecting bracket and the motor assembly, the connecting bracket and the motor assembly can be respectively in elastic connection, so that two elastic connections exist between the motor assembly and the stirring assembly, the buffering effect of connection between the motor assembly and the stirring assembly can be greatly improved, and the vibration reduction and noise reduction are facilitated. In addition, the motor assembly and the stirring assembly need to transmit torque coaxially, and once deviation exists in coaxiality, strong vibration and vibration noise are generated.
