[0039] In this embodiment, the peripheral side surface of the hollow seat 31 is welded and fixed with L-shaped heat dissipation rods 315, one end of the L-shaped heat dissipation rod 315 extends into the hollow seat 31 and is located below the movable plate 32, the other end of the L-shaped heat dissipation rod 315 is welded and fixed with the top of the bottom plate 37, the number of L-shaped heat dissipation rods 315 is set to be multiple, and the plurality of L-shaped heat dissipation rods 315 are distributed in equal intervals in a ring shape. The hollow seat 31, the L-shaped heat dissipation rod 315 and the bottom plate 37 are all made of stainless steel, and the plurality of L-shaped heat dissipation rods 315 are designed to dissipate the heat generated during the damping process in time, a part of the heat is dissipated in the air, and another part of the heat is transmitted to the ground through the bottom plate 37, so as to avoid the performance degradation of the damping support seat 3 due to the heat accumulation caused by long-time work, and maintain the high damping performance of the damping support seat 3.

[0040] In this embodiment, the bottom surface of the bottom plate 37 is provided with anti-skid lines, the design of the anti-skid lines increases the friction with the ground, prevents the damping support seat 3 from sliding and shifting during the operation of the flat rotary screen main body 2, ensures the stable installation of the equipment, guarantees the safety of the rice processing process, reduces the safety hidden dangers and processing accidents caused by the sliding of the equipment.

[0041] By the above structure, the rice processing flat sieve damping device provided by the application can reduce the vibration of the flat sieve main body 2 during the rice processing operation, and the vibration force is transmitted to the bearing plate 1, which transmits the vibration force to the plurality of damping support seats 3. At this time, the bearing plate 1 will drive the top plate 35 to move slightly in the vertical direction, and the top plate 35 will drive the vertical movement of the column 34, the movable plate 32 and the damping ring 33. A plurality of equally spaced damping springs 36 can absorb and disperse the vibration energy from the bearing plate 1, convert the vibration into elastic potential energy of the spring, and use the damping force generated by the movement of the damping ring 33 to suppress the reciprocating bounce of the plurality of damping springs 36, thereby achieving preliminary energy absorption and damping. At the same time, the space below the movable plate 32 changes constantly during the movement of the movable plate 32 in the hollow seat 31. When the space becomes smaller, the air inside is compressed, and the force of the compressed air will push the movable plate 32 and the damping ring 32 to move in the fixed cylinder 39. The damping spring 312 is deformed under stress, absorbing the remaining vibration energy. The damping force generated by the damping ring 311 can suppress the reciprocating bounce of the damping spring 312, so that the vibration generated by the flat sieve main body 2 during operation can be greatly reduced through the cooperation of the damping spring 36, the damping ring 33, the damping spring 312 and the damping ring 311, thereby achieving the effect of effective damping and greatly reducing the noise caused by vibration.

[0042] During the damping process, the heat generated by the damping support seat 3 is transmitted through the plurality of L-shaped heat dissipation rods 315, so that part of the heat is dissipated in the air, and another part of the heat is transmitted to the bottom plate 37, and then transmitted to the ground through the bottom plate 37, thereby realizing efficient dissipation of heat on the damping support seat 3, avoiding performance degradation due to heat accumulation of the damping support seat 3, and ensuring continuous and efficient operation of the damping support seat 3.
