Description

Non-contact scraper mounting rotator

Technical Field

The utility model belongs to the technical field of clear stifled machine, concretely relates to non-contact scraper installation rotator.

Background

The important part on the clear stifled machine is the rotator, and current rotator has following shortcoming:

1. the revolving body and the bearing inner ring are integrated, the manufacturing requirement precision is high, and the cost is high;

2. the included angle between the inside of the revolving body and the upper and lower bin bodies is larger than 90 degrees, and the manufacturing difficulty of the scraper is high.

3. The scraper has few fixing bolts and is easy to fall off.

4. The sealing packing is not easy to replace.

5. The sealing between the revolving body and the upper and lower bin bodies is not tight, and powder is easy to leak, thereby causing environmental pollution and bearing damage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect among the prior art and provide a structural design is reasonable, and is sealed effectual, can not take place the dust and reveal and scraper simple to operate clearly stifled effectual non-contact scraper installation rotator.

The purpose of the utility model is realized like this: the automatic plug cleaning machine comprises a speed reducer connected with a motor, wherein a pinion of the speed reducer is meshed with a rotary bearing outer ring on a rotary body to realize radial connection, the rotary body is fixed to the rotary bearing outer ring through a bolt in the axial direction, a first packing on an upper sealing surface of the rotary body is matched with a lower flange sealing surface of a plug cleaning machine cabin body, a second packing on a lower sealing surface of the rotary body is matched with an upper flange sealing surface of the plug cleaning machine cabin body, and an upper scraper and a lower scraper are symmetrically arranged on the inner side of the rotary body.

Preferably, the upper scraper and the lower scraper are obliquely arranged on the inner side wall of the rotating body and are consistent with the inclination angle of the inner wall of the rotating body.

Preferably, the inclination angle is 77 °.

Preferably, the upper scraper and the lower scraper are fixed on the scraper seat through threaded holes.

Preferably, the number of the threaded holes is 12.

The utility model has the advantages of structural design is reasonable, and is sealed effectual, can not take place the dust and reveal and scraper simple to operate is clear stifled effectual.

Drawings

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, in which like reference numerals refer to like parts in the drawings. For the sake of simplicity, only the parts related to the utility model are schematically shown in the drawings, and they do not represent the actual structure as a product.

As shown in fig. 1 and 2, the utility model relates to a non-contact scraper installation rotator, include the speed reducer 2 that links to each other with motor 1, radial connection is realized in the meshing of slewing bearing outer lane 5 on pinion 3 of speed reducer 2 and the rotator 4, it is fixed through bolt 6 between the axial of rotator 4 and the slewing bearing outer lane 5, first packing 8 on the last sealed face 7 of rotator 4 and the sealed face 9 looks adaptation of the lower flange of the clear stifled cabin body, second packing 11 on the lower sealed face 10 of rotator 4 and the sealed face 12 looks adaptations of the last flange of the clear stifled cabin body, upper scraper 13 and lower scraper 14 are installed to the inboard symmetry of rotator 4.

Further, the upper scraper 13 and the lower scraper 14 are arranged on the inner side wall of the rotating body 4 in an inclined manner and are consistent with the inclined angle of the inner wall of the rotating body 4; the inclination of the upper bin body and the lower bin body of the blockage removing machine is close, so that the scraper can be conveniently installed, and blockage removing and blanking are facilitated.

Further, the inclination angle is 77 °.

Further, the upper scraper 13 and the lower scraper 14 are fixed on a scraper seat 16 through a threaded hole 15; the fixing and fastening are realized, and the stability is ensured during the work.

Further, the number of the threaded holes 15 is 12.

The utility model discloses power passes through motor 1 and drives speed reducer 2 and then drive speed reducer pinion 3 and rotate, and it is rotatory to drive rotator 4 through the gear wheel transmission integrative with 5 slewing bearing outer lanes, passes power to scraper 13 and lower scraper 14, realizes the clear stifled purpose of stifled machine of clearing up.

The utility model discloses first packing 8 on the last sealed face 7 of rotator 4 and the sealed 9 looks adaptations of the lower flange of the clear stifled cabin body, second packing 11 on the 4 lower sealed faces 10 of rotator and the sealed 12 looks adaptations of the last flange of the clear stifled cabin body form a mechanical seal and the sealed double sealing rotary device of packing, make the likepowder granule in the storehouse not reveal when the wind pressure is used.

The above examples are merely illustrative for clarity and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art upon reference to the above description. It is not necessary or necessary to exhaustively enumerate all embodiments herein, and obvious variations or modifications can be made without departing from the scope of the invention as claimed.
