Description

Discharge rotor cover plate of grinder

Technical Field

The utility model relates to grinding mill accessories, in particular to a grinding mill discharge rotor cover plate.

Background

The discharge rotor cover plate is a plate-shaped structure used for supporting a discharge pipe at the discharge end of a spindle discharge type grinding machine, and because the state does not have the standard of the product, part of production enterprises also refer to the part as a front cover plate and refer to a discharge pipe connecting structure with a conical groove as a discharge cover plate. Only the "outfeed rotor cover plate", i.e. the "front cover plate", is discussed herein.

The existing discharging rotor cover plate has the defects that: the discharge pipe is a whole round metal plate (refer to a discharge device suitable for a grinding machine in Chinese patent No. 201220593715.9 as shown in figure 1), which is beneficial to vibration conduction, and the discharge pipe is sleeved with a main shaft, so that high-frequency vibration is inevitable, and the bolt connection part of a discharge rotor cover plate and other parts is easy to loosen after long-term use.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a grinding machine discharging rotor cover plate with a vibration reduction function.

The technical scheme of the utility model is as follows:

grind quick-witted ejection of compact rotor apron, it includes inner ring, outer loop, inner ring central authorities are provided with a through-hole for cup joint the discharging pipe that has the bell mouth, the outer loop is connected through a plurality of damping spokes in the inner ring periphery, the damping spoke equidistance sets up.

Furthermore, the damping spoke material is the damping alloy, because inner ring and outer loop are all necessarily the metal material, so use the damping alloy to make the damping spoke, do benefit to and weld or stamping forming with inner ring and outer loop.

Furthermore, a plurality of discharge pipe connecting holes are formed in the inner ring and used for connecting the discharge pipes, and a plurality of grinding machine connecting holes are formed in the outer ring and used for connecting the grinding machine shell.

Furthermore, the damping spokes are thick at two ends and thin in the middle, and the damping spokes have the advantages that the area of the joints between the damping spokes and the inner ring and the area of the joints between the damping spokes and the outer ring are increased, and the connection strength is improved.

The utility model has the beneficial effects that: the whole body is made of metal, so that the strength is high; the inner ring is used for connecting the discharging pipe, and the outer loop is used for connecting the machine of grinding, connects through the damping spoke between inner ring and the outer loop, can reduce the discharging pipe shake to the impact of grinding mill shell and bolt isotructure, avoids each junction to appear becoming flexible, has still objectively reduced the noise.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a perspective view of the present invention.

In the figure, 1, inner ring; 2. an outer ring; 3. damping spokes; 4. a through hole; 5. connecting holes of the discharge pipe; 6. the grinder is attached to the hole.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings:

as shown in figures 1 and 2, the discharging rotor cover plate of the grinding mill comprises an inner ring 1 and an outer ring 2, wherein a through hole 4 is formed in the center of the inner ring 1 and used for being sleeved with a discharging pipe with a conical groove, the periphery of the inner ring 1 is connected with the outer ring 2 through a plurality of vibration reduction spokes 3, and the vibration reduction spokes 3 are arranged at equal intervals.

The damping spoke 3 is made of damping alloy (in this embodiment, an iron-based damping alloy with high damping characteristics is adopted, see the chinese patent 201410192612.5 for details), and because the inner ring 1 and the outer ring 2 are both necessarily made of metal, the damping spoke 3 is made of damping alloy, which is beneficial to welding or punch forming with the inner ring 1 and the outer ring 2.

The inner ring 1 is provided with a plurality of discharge pipe connecting holes 5 for connecting discharge pipes, and the outer ring 2 is provided with a plurality of grinding machine connecting holes 6 for connecting a grinding machine shell.

The damping spokes 3 are thick at two ends and thin in the middle, and the damping spokes have the advantages that the area of the joints between the damping spokes and the inner ring 1 and the outer ring 2 is increased, and the connection strength is improved.

The working principle of the utility model is as follows:

the inner ring is sleeved with the discharge pipe, the outer ring is connected with the end part of the grinding machine and fastened through bolts, and then discharge is started. Because the discharging pipe can take place certain shake owing to arrange material motion and main shaft rotation in-process to drive the inner ring shake, thereby partial vibration is absorbed by it and slows down vibration and conduct to the outer loop when vibration conduction is conducted to the damping spoke, finally plays the damping effect.

The foregoing embodiments and description have been presented only to illustrate the principles and preferred embodiments of the utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model as hereinafter claimed.

Claims
