Abstract
The utility model discloses a circular sieve machine and relates to the technical field of tea making equipment. The circular sieve machine comprises a circular sieve mounted on a frame and provided with an eccentric shaft, wherein the lower part of the eccentric shaft is connected with a rotary table fixed on the frame through a bearing sleeved on the rotary table. Compared with the prior art, the circular sieve machine can solve the problems that a current circular sieve machine is required to maintain and replace parts frequently and is low in working efficiency.
Description
Technical field
The utility model relates to tea prepn equipment technology for making field, especially a kind of machine that gross tea is carried out to vibrosieve length.
Background technology
Plane-surface round sifter is one of main screening plant in tealeaves finishing step, also be irreplaceable equipment in Tea Processing, use this equipment to sieve different tealeaves, tealeaves identical length is collected, thereby obtain the gross tea of various different sizes.Have a kind of circular screening machine, this circular screening machine comprises respectively and is contained in the rotary strainer in frame by active eccentric and driven eccentric, and initiatively eccentric is connected with engine; Described driven eccentric dress comprises by bearing and is contained in the rotating shaft in frame, and the top of described rotating shaft is provided with eccentric block, and described eccentric block is connected with rotary strainer by the eccentric shaft of establishing thereon.In use there are the following problems for the circular screening machine of this structure: when 1, eccentric shaft rotates around the shaft with rotary strainer; because rotating shaft is relatively elongated; easily produce bearing inner race unbalance stress that flexural deformation makes to be contained in rotating shaft two ends and serious wear; cause the stationarity of rotary strainer running poor; needs are often shut down and are keeped in repair, renewal part, inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of circular screening machine, this circular screening machine can solve existing circular screening machine need often to shut down keep in repair, renewal part, ineffective problem.
In order to address the above problem, the technical solution adopted in the utility model is: this circular screening machine comprises the rotary strainer that is provided with eccentric shaft being contained in frame, in the bottom of described eccentric shaft, is connected with rotating disk, and described rotating disk is fixed in frame by suit bearing thereon.
In technique scheme, technical scheme can also be more specifically: described eccentric shaft and described rotating disk are welded to connect.
Owing to having adopted technique scheme; the utility model compared with prior art has following beneficial effect: rotary strainer is by being welded on rotating disk with eccentric shaft; substituted original rotating shaft with rotating disk; eliminated the yielding hidden danger that bearing inner race compressing is caused to bearing wear that causes of rotating shaft; need not often shut down keep in repair, renewal part, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the circular screening machine of prior art.
Fig. 2 is the structural representation of the utility model circular screening machine.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Be illustrated in figure 1 the circular screening machine of prior art, this circular screening machine comprises respectively and is contained in the rotary strainer 1a in frame by active eccentric and driven eccentric, and initiatively eccentric is connected with engine; Driven eccentric dress comprises by bearing 6a and is contained in the rotating shaft 5a in frame, the top of rotating shaft 5a has been coated with eccentric block 4a, on eccentric block 4a, be coated with rotating shaft 5a and be the eccentric shaft 3a that offset distance arranges, it is upper that eccentric shaft 3a is contained in eccentric mounting 2a by bearing, and eccentric mounting 2a is bolted on the bottom of rotary strainer 1a.The eccentric shaft 3a of this structure is with rotary strainer 1a 5a when rotation around the shaft; because rotating shaft 5a is relatively elongated; easily produce inner ring unbalance stress that flexural deformation makes to be contained in rotating shaft 5a bearings at both ends 6a and serious wear; cause the stationarity of rotary strainer running poor; needs are often shut down and are keeped in repair, renewal part, inefficiency.
Circular screening machine as shown in Figure 2 comprises by bolt and is contained in the eccentric mounting 2 on rotary strainer 1, on eccentric mounting 2, be fitted with eccentric shaft 3, in the bottom of eccentric shaft 3, be connected with rotating disk 4, rotating disk 4 and the eccentric shaft 3 of the present embodiment are welded to connect, rotating disk 4 centers and eccentric shaft 3 centers be offset distance setting, rotating disk of the present utility model 4 centers equate to the distance of eccentric shaft 3a to the distance at eccentric shaft 3 centers and the rotating shaft 5a of prior art rotary strainer, and two segment distances are all a value, and a of the present embodiment is 37 millimeters; Rotating disk 4 is contained on bearing block 7 by suit bearing 5 thereon, and bearing block 7 is bolted in frame 6.
Because rotary strainer 1 is by being welded on rotating disk 4 with eccentric shaft 3; rotating disk 4 is fixed in frame 6 by bearing; substituted original rotating shaft 5a with rotating disk 4; eliminated the yielding hidden danger that bearing inner race compressing is caused to bearing wear that causes of rotating shaft; need not often shut down keep in repair, renewal part, improved operating efficiency.
Claims (2)
1. a circular screening machine, comprise the rotary strainer that is provided with eccentric shaft (3) (1) being contained in frame (6), it is characterized in that: in the bottom of described eccentric shaft (3), be connected with rotating disk (4), described rotating disk (4) is fixed in frame (6) by suit bearing (5) thereon.
