[0046] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] In order to solve the technical problem that the upper and lower shells of the polishing machine are directly hard-connected, which causes the polishing machine to vibrate, the utility model provides a main structure of the polishing machine, which can slow down the transmission of the polishing machine vibration.

[0048] It should be noted that the main structure of the polishing machine described in the present invention is used for but not limited to rice polishing machines, etc. For the convenience of explanation, in the present invention, only the main structure of the polishing machine is applied to rice polishing equipment as an example for explanation. The principle of applying the main structure of the polishing machine to other types of equipment is essentially the same as the principle applied to the rice polishing equipment, and will not be repeated here.

[0049] See also Figures 1 to 3 The main structure of a polishing machine includes a base 1, a buffer and vibration reduction component 2, a bran collecting hopper 3 and a frame 4. The buffer and vibration reduction component 2 includes a vibration reduction pad 21, which is connected to the base 1 and is arranged on the top of the base 1; the bran collecting hopper 3 is built into the base 1, and a rib 31 is formed on the top, and the rib 31 is arranged on the side of the vibration reduction pad 21 away from the base 1; the frame 4 is arranged on the side of the rib 31 away from the base 1, and is detachably connected to the base 1. The frame 4 is used to fix the polishing structure of the polishing machine.

[0050] Specifically, in the present invention, the base 1 and the frame 4 are connected in a detachable manner, so that the base 1 and the frame 4 can be processed and transported separately, which is convenient for manufacturing and transportation; by forming the bran collecting bucket 3 into a baffle, and arranging the baffle between the vibration-damping pad 21 and the frame 4, the bran collecting bucket 3 is fixed by clamping the frame 4, the base 1 and the vibration-damping pad 21; by arranging the vibration-damping pad 21 between the frame 4 and the base 1, when the rice polisher is working, the vibration generated by the rotation and polishing of the polishing structure is transmitted to the frame 4, and is transmitted to the vibration-damping pad 21 through the frame 4, and the vibration transmitted to the frame 4 is damped by the vibration-damping pad 21, thereby slowing down or buffering the vibration transmitted to the base 1.

[0051] It should be understood that the material of the vibration damping pad 21 can be rubber, foam, sponge, etc.

[0052] It should be understood that the base 1 and the frame 4 can be a bracket and a frame formed by splicing various profiles, plates, etc.

[0053] It should be understood that the ribs 31 can be provided on both sides of the bran collecting hopper 3 . In one embodiment, the baffle is provided around the bran collecting hopper 3 .

[0054] It should be understood that the above-mentioned polishing structure is the polishing roller and screen of the rice polishing machine.

[0055] Since the retaining edge 31 of the bran collecting hopper 3 is provided between the vibration damping pad 21 and the frame 4, there will be a distance between the side of the frame 4 that does not correspond to the baffle and the vibration damping pad, which will affect the balance of the frame 4. Therefore, in one embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, the buffer vibration reduction assembly 2 further includes a gasket 22 . The gasket 22 is disposed on the vibration reduction pad 21 , away from the side of the base 1 , and the gasket 22 is disposed between the frame 4 and the vibration reduction pad 21 .

[0056] By arranging a gasket 22 between the vibration damping pad 21 and the frame 4, the gasket 22 can fill the gap between the side of the frame 4 not corresponding to the retaining edge 31 and the vibration damping pad 21, thereby preventing the gap from affecting the balance and stability of the machine body.

[0057] like Figure 2 and Figure 3 As shown, in one embodiment, the thickness of the gasket 22 is equal to the thickness of the rib 31 .

[0058] By setting the thickness of the gasket 22 to be equal to the thickness of the rib 31 , the bottom of the frame 4 can be supported by the flush gasket 22 and the rib 31 , thereby effectively maintaining the balance of the frame 4 .

[0059] During assembly, the vibration damping pad 21 is first placed on the base 1, and then the rib 31 is placed on the vibration damping pad 21. However, during the placement of the rib 31, the vibration damping pad 21 may move relative to the base 1, causing the installation position of the vibration damping pad 21 to shift. Therefore, in one embodiment, as shown in FIG. Figure 6 As shown, the buffer vibration reduction assembly 2 further includes an adhesive layer 23 . The adhesive layer 23 is disposed on a side of the vibration reduction pad 21 close to the base 1 and is bonded to the base 1 .

[0060] By setting an adhesive layer 23 on the side of the shock-absorbing pad opposite to the base 1, during the installation of the shock-absorbing pad 21, the shock-absorbing pad 21 is bonded to the base 1 through the adhesive layer 23, thereby fixing the position of the shock-absorbing pad 21 and preventing the shock-absorbing pad 21 from moving relative to the base 1 during subsequent installation.

[0061] It should be understood that the adhesive layer 23 can be a solid adhesive, a double-sided tape, etc.

[0062] like Figure 7As shown, in one embodiment, a plurality of threaded holes 1a are formed on the top of the base 1, and a plurality of first through holes 21a are formed on the vibration damping pad 21 relative to the threaded holes 1a, and the first through holes 21a are arranged in a one-to-one correspondence with the threaded holes 1a.

[0063] By opening multiple first through holes 21a on the vibration damping pad 21, and the first through holes 21a correspond one-to-one to the threaded holes 1a, during the installation of the vibration damping pad, the multiple first through holes 21a are aligned with the multiple threaded holes 1a, so that the vibration damping pad 21 can be positioned during the installation process.

[0064] like Figure 6 As shown, in one embodiment, the gasket 22 defines a second through hole 22 a opposite to the first through hole 21 a.

[0065] By forming a second through hole 22a on the gasket 22 relative to the first through hole 21a, the gasket 22 can be positioned during installation by aligning the second through hole 22a with the corresponding first through hole 21a on the shock-absorbing pad.

[0066] like Figure 5 As shown, in one embodiment, the frame 4 is provided with a plurality of third through holes 4a relative to the threaded holes 1a, and the third through holes 4a are arranged in a one-to-one correspondence with the threaded holes 1a.

[0067] By providing a plurality of third through holes 4 a on the rack 4 relative to the threaded holes 1 a , when the rack 4 is installed, the rack 4 to be installed can be positioned by matching the third through holes 4 a with the threaded holes 1 a .

[0068] like Figure 4 As shown, in one embodiment, the rib 31 is provided with a plurality of fourth through holes 31 a relative to the threaded hole 1 a.

[0069] By opening a plurality of fourth through holes 31a on the retaining edge 31 relative to the threaded hole 1a, during the process of installing the retaining edge 31 on the vibration damping pad 21, the first through holes 21a of the vibration damping pad 21 correspond one-to-one with the threaded holes 1a, and the fourth through holes 31a on the retaining edge 31 are aligned with the corresponding threaded holes 1a, thereby realizing the positioning of the retaining edge 31 relative to the base 1.

[0070] It should be understood that the frame 4 and the base 1 can be detachably connected by bolts, screws, buckles, etc. In one embodiment, Figure 1 and Figure 2 As shown, the main structure of the polishing machine also includes a connecting assembly 5, which includes a plurality of first connecting bolts 51. The threaded ends of the first connecting bolts 51 pass through the third through hole 4a, the fourth through hole 31a and the first through hole 21a, and are threadedly connected to the threaded hole 1a.

[0071] By passing the threaded end of the first connecting bolt 51 through the third through hole 4a, the fourth through hole 31a and the first through hole 21a, the threaded end of the first connecting bolt 51 is able to pass through the frame 4, the retaining edge 31 and the vibration damping pad 21, and be threadedly connected to the threaded hole 1a, thereby realizing the connection between the frame 4 and the base 1, and realizing the fixation between the base 1, the vibration damping pad 21, the bran collecting hopper 3 and the frame 4.

[0072] like Figure 1 and Figure 2 As shown, in one embodiment, the connecting assembly 5 further includes a second connecting bolt 52, a threaded end of the second connecting bolt 52 passes through the third through hole 4a, the second through hole 22a and the first through hole 21a, and is threadedly connected to the threaded hole 1a.

[0073] By passing the threaded end of the second connecting bolt 52 through the third through hole 4a, the second through hole 22a and the first through hole 21a, the threaded end of the second connecting bolt 52 is able to pass through the frame 4, the gasket 22 and the shock-absorbing pad, and be threadedly connected to the threaded hole 1a, thereby achieving fixation between the base 1, the shock-absorbing pad 21, the gasket 22 and the frame 4.

[0074] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
