Abstract

The utility model relates to the field of tea processing equipment, in particular to a tea screening device comprising a filter screen and a drive unit. The filter screen is suspended by means of elastic support. The drive unit comprises a motor and a turnplate. The motor drives the turnplate to rotate around a spindle of the turnplate in the horizontal plane. The spindle of the turnplate is disposed at the center of the surface of the turnplate. An auxiliary shaft of the turnplate and the spindle are spaced at certain distance. The bottom of the filter screen is in hinged fit with the auxiliary shaft. The novel drive mode allows the filter screen to move in the horizontal range, the effect of manual tea screening is fully simulated, tea injury is little while the tea is screened, and in addition, the tea screening device which is automated is higher in screening efficiency and low in labor cost.

Description

Tea screening device

Technical field

The utility model relates to tea-processing equipment field, particularly a kind of tea screening device.

Background technology

Black tea is a kind of full fermentation teamain Tea product in the tea culture of ，Shi west.Black tea can help gastro-intestinal digestion, promote appetite to have the effect of diuresis, elimination oedema, strong heart, can also play in addition prevention decayed tooth, food poisoning, reduces the effect of blood sugar and blood pressure.Black tea be through plucking, wither, knead, fermentation, drying and other steps produces, general fermentation, the dry semi-finished product black tea making later also needs through again drying sterilization, could on market, sell after mixing, sieve, packing.

When tealeaves is sieved, need to use tea screening device.Traditional tea screening device mostly is vibration-type, and the screening plant of this mode is easily shatter by tealeaves, damages the original form of tealeaves; During artificial screening, by manual operation sieves, make sieves in horizontal extent, do the circular motion moving in circles, this screening mode is comparatively soft, but owing to being pure manual operations, is unfavorable for large-scale production.

Utility model content

The purpose of this utility model is to provide a kind of tea screening device, can fully simulate artificial screening mode, reduces tealeaves damage when tealeaves is carried out to effectively screening.

For realizing above object, the technical solution adopted in the utility model is: a kind of tea screening device, comprise sieves, driver element, described sieves is by resiliency supported the shape that suspends and arranges, described driver element comprises motor, rotating disk, and described motor drives rotating disk to rotate in horizontal plane around its main shaft, and the main shaft of rotating disk is positioned at card center position, the setting that is spaced a distance of the countershaft of rotating disk and main shaft, the bottom of sieves coordinates with described countershaft is hinged.

Compared with prior art, there is following technique effect in the utility model:

Owing to having adopted new type of drive, sieves is taken exercises in horizontal extent, fully simulated the effect of artificial screening tealeaves, also less to the damage of tealeaves when assurance realizes screening to tealeaves, in addition, this device is for automatically, improve screening efficiency, less cost of labor.

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 7, the utility model is described in further detail:

Consult Fig. 1, Fig. 2, a kind of tea screening device, comprise sieves 10, driver element 20, described sieves 10 is by resiliency supported the shape that suspends and arranges, because whole device is positioned on ground, resiliency supported can be that shaft-like support or rope form hang, mainly make sieves 10 be suspended in above the ground, described driver element 20 comprises motor 21, rotating disk 22, described motor 21 drives rotating disk 22 to rotate in horizontal plane around its main shaft 221, the main shaft 221 of rotating disk 22 is positioned at card center position, the setting that is spaced a distance of the countershaft 222 of rotating disk 22 and main shaft 221, the bottom of sieves 10 coordinates with described countershaft 222 is hinged.Like this, when rotating disk 22 is when its main shaft 221 rotates, countershaft 222 moves in a circle around main shaft 221, sieves 10, under the driving of countershaft 222, is also done same circular motion, but because sieves 10 and countershaft 222 are hinged cooperation, therefore, the motion class that sieves 10 is done is like doing translation along the movement locus of countershaft 222, very similar to artificial sieve tea mode, and the effect of its screening tealeaves is also better.

Consult Fig. 4, Fig. 5, as preferred version of the present utility model, described countershaft 222 is arranged on rotating disk 22 edge, is provided with balancing weight 223 with opposite side rotating disk 22 upsides and/or the downside of countershaft 222 symmetries, stability when the arranging of balancing weight 223 guarantees that rotating disk 22 rotates.Hinged cooperation between countershaft 222 and sieves 10 can be: on described countershaft 222, be provided with bearing and be fixedly connected with the bottom of sieves 10; Or between countershaft 222 and rotating disk 22, bearing is set, and two schemes there is no essential distinction, and what in the utility model, adopt is front a kind of scheme.

Consult Fig. 2, in actual screening tealeaves, not only need screening to fall the impurity in tealeaves, sometimes, also need the tealeaves of variable grain size to carry out sorting.Therefore, described sieves 10 comprises screen frame (unit) 11 and is arranged on the screen cloth 12 in screen frame (unit) 11; Described screen frame (unit) 11 is the box-like of lateral openings, described screen cloth 12 is skewed layout, the number of plies of screen cloth 12 is arranged according to actual needs, it should be noted that, the screen cloth 12 that is positioned at upside is comparatively sparse, more past lower screen cloth 12 is closeer, and screen frame (unit) 11 tops that are positioned at the higher side of screen cloth 12 are provided with charging aperture 111, a discharging opening 112 of corresponding layout on the screen frame (unit) 11 of every layer of lower side of screen cloth 12.

Equally, when the tealeaves sieving is different, the specification of screen cloth 12 is also different, and in order to be applicable to more occasions, described screen cloth 12 comprises that wooden framework 121 and screen cloth 122 are made into integration, and described framework 121 is Tian Zizhuan, as shown in Figure 6; Described 11 two relative medial surfaces of screen frame (unit) are provided with limit track 113, and described framework 121 forms locating slip with limit track 113 and coordinates, as shown in Figure 3.Screen cloth 12 is detachable with respect to sieves 10, according to different tealeaves demands, selects the screen cloth 12 of different meshes.In addition, when screen cloth 12 has breakage, also can disassemble and change.

Because whole device is arranged in factory building, the height of factory building is higher, sieves 10 adopts rope to hang and is rather amiss, sieves 10 described in the utility model is supported by support 30, when guaranteeing that sieves 10 obtains support 30 and effectively supports, can also carry out translational motion along the movement locus of countershaft 222, support 30 adopts following scheme setting:

Consult Fig. 7, support 30 comprises base 31, the body of rod 32, and described base 31 fixes on the ground, and the body of rod 32 is hinged by universal joint and base 31; Described sieves 10 bottom periphery are provided with holder 13 and are connected with body of rod 32 upper end.Described holder 13 has four, is arranged symmetrically in respectively screen frame (unit) 11 both sides; Each holder 13 place arranges a support 30.On described holder 13, offer the diameter that the through hole of up/down perforation and the diameter of through hole are greater than the body of rod 32, holder 13 is set on the body of rod 32 and is resisted against on the first locating part 321 arranging on the body of rod 32, be positioned on the body of rod 32 of holder 13 upsides and be provided with the second locating part 322, between first and second locating part 321,322 and holder 13, be provided with rubber blanket 33.

In " the tea screening device support bar " that above scheme is applied on the same day in our company and " tea screening device fixture ", be documented, repeat no more herein.The selection that it is pointed out that support 30 is not unique, if can guarantee sieves 10 secure support, motion be not obstructed.
