Description

A kind of plane-surface round sifter

Technical field

The utility model belongs to tea prepn equipment field, and more specifically, the utility model relates to a kind of tea screening devices.

Background technique

Plane-surface round sifter is suitable for refining the processing of tealeaves, in process according to bar shaped tea, circular tea, block shape tea Granular size carries out sub-sieve operation.To reduce the damage to tealeaves, the sieve plate running track of plane-surface round sifter imitates sieve tea by hand Mode, there is the screening part whole (including shell) of inclination sieve plate in the horizontal plane by crank handle turns using the motor of bottom end It circles, spreads out tealeaves uniformly on sieve plate, biggish blade stays in above sieve plate during movement, lesser leaf Piece is fallen below sieve plate by sieve pore.

Sieve pore easily blocks during circular screening machine is run, and is easily made using conventional method such as scraper plate, nail-plate etc. come logical sieve Tealeaves is damaged, and reduces the grade of tealeaves, influences income.

Utility model content

The utility model provides a kind of plane-surface round sifter, and hitting sieve plate upwards by compartment of terrain makes its vibration to dredge The sieve pore of blocking, to reduce the damage led to during sieve to tealeaves.

To achieve the above object, the utility model uses the following technical solution:

A kind of plane-surface round sifter, including shell, be obliquely set to the intracorporal sieve plate of shell, further include with it is solid in inner walls The ram of fixed holder pivots connection；Housing top surface offers feed inlet；Sieve plate low side and housing sidewall are hinged, housing sidewall Discharge port is offered above hinged place；Sieve plate is high-end to be overlapped on the ram.

Compared with the prior art, the utility model has the following beneficial effects:

Sieve plate bottom is hit by ram, shakes sieve plate, so that the tealeaves blocked in sieve pore be shaken out.This is practical new Type structure is simple, and the mode for leading to sieve is also more mild, is not easy to cause damage on tealeaves and influence tea leaf quality.

The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through Research and practice of the invention are understood by the person skilled in the art.

Appended drawing reference in Figure of description include: shell 1, sieve plate 2, ram 3, feed inlet 4, discharge port 5, chain 6, Crash panel 7, sliding rail 9, advertises device 10, air blower 11, rocking handle 12 at roller 8.

Specific embodiment

In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to Understand, the utility model be further elaborated with reference to the accompanying drawings and detailed description:

Such as Fig. 1, a kind of plane-surface round sifter including shell 1, is obliquely set to sieve plate 2 in shell 1, further includes and shell The ram 3 of fixed holder pivots connection on 1 inner wall of body；1 top surface of shell offers feed inlet 4；2 low side of sieve plate and shell 1 Side walls hinged, 1 side wall of shell offers discharge port 5 above hinged place；Sieve plate 2 is high-end to be overlapped on the ram 3.

When the sieve pore blockade of sieve plate 2, control ram 32 bottom of sieve plate is hit, make sieve plate 2 be shaken and The tealeaves of most of blocking sieve pore is shaken, achievees the purpose that dredge sieve pore.

Preferably, the shell 1 is rectangle, and the sieve plate 2 is multiple groups and is arranged in parallel, and lower layer's sieve plate 2 The sieve pore of the small sieve plate of layer thereon 2 of sieve pore；The ram 3 distribution identical and upper and lower with 2 quantity of sieve plate, passes through each shock Fixed sprocket wheel and the linkage of each ram 3 is realized with the chain 6 of each sprocket engagement on part 3.Each linkage of ram 3 makes logical sieve Process is simpler, easily operated.Chain 6 has also meshed with a driving wheel, and driving wheel rotary shaft is fixedly connected with across shell 1 Rocking handle 12.In addition, motor, if selecting motor, can should be also fixedly installed in inside shell 1 by driving wheel by motor driven, It is only stayed outside shell 1 and sets switch.

When tea efficiency out reduces, can suspend circular screening machine circular motion (Patent No. CN201720796582.8's Utility model patent discloses the concrete mechanism that circular screening machine moves in a circle, and it is the public affairs of this field that circular screening machine, which moves in a circle, Know common sense, be also not belonging to present invention point, therefore, not repeat them here), logical sieve mode is hit in starting, makes ram 3 to sieve plate 2 It is hit, and temporarily dredges most of sieve pore, or logical sieve is timed to circular screening machine.Without sieve plate 2 being taken out clearly every time Reason or because use scraper plate or needle plate etc. to tealeaves caused by damage, improve the working efficiency of circular screening machine significantly, reduce production Cost.

Such as Fig. 2, it is preferred that the ram 3 is by rotary shaft and several circularizes array about rotating shaft center's line Crash panel 7 forms；Rotation axis horizontal setting, and connect with the bracket by bearing.Multiple crash panels 7 circularize array and set It sets, makes it that there is continuity to the shock of sieve plate 2, and fix crash direction, machine is stable, in addition, passing through selection Plate appropriate is long and quantity, it is ensured that sieve plate 2 is always positioned at 7 top of crash panel, and will not fall to 7 lower section of crash panel and to making With bringing inconvenience.

Some researches show that the tilt angles of sieve plate 2 largely to affect the screening effect of plane-surface round sifter；Circular screening machine Entirety is when moving in a circle, and can adjust 2 inclination angle of sieve plate by adjusting the height of its 7 end of crash panel when static of ram 3 Degree, to control screening effect.

Preferably, one end that the crash panel 7 is contacted with sieve plate 2 is provided with roller 8.The setting of roller 8, which can reduce, hits Plate 7 and sieve plate 2 are hit with respect to the frictional dissipation generated in sliding process, extends the service life of equipment.

Such as Fig. 3, it is preferred that be fixed with the sliding rail 9 being obliquely installed below bottom sieve plate 2 in the shell 1, make sliding rail Distance is kept relative constant between 9 and sieve plate 2；It is slidably connected on the sliding rail 9 and advertises device 10, the device 10 of advertising has Bar shaped gas outlet, gas outlet opening upwards, it is described advertise device 10 by pass through shell 1 piping connection be set to shell 1 Outer air blower 11.For the most thin sieve plate 2 of bottom setting, simple shake is extremely difficult to the effect of dredge blockage, therefore And can be selected and advertise device 10 to up-draught to be dredged, such method is also not easy to cause to damage to tealeaves.To guarantee wind-force, The utility model reduces air outlet, is set as bar shaped, and makes wind-force Relatively centralized, to reach the effect of the sieve pore of dredge blockage Fruit.It advertises device 10 in use, need to only open and keeps it slow along sliding rail 9 by the conventional driving method such as hydraulic stem, push rod, drawstring Slow sliding can successively dredge the sieve pore of entire sieve plate 2.Because sieve plate 2 is to be obliquely installed, so only sliding rail 9 is also tilted and is set It sets, distance is kept relative constant between sieve plate 2, just can guarantee that distance change will not be excessive between air outlet and sieve plate 2, to guarantee The effect stability of wind-force dredging.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
