Description

A kind of Tea screening machine

Technical field

The utility model relates to a kind of tea-processing equipment, and particularly a kind of Tea screening machine, belongs to machine for processing tea technical field.

Background technology

Along with the development of modern technologies, processing field of tea leaves has progressively entered automation age, and production of machinery starts a large amount of traditional manual works that replace, and the machinery production efficiency of tealeaves is high, output is large, can meet the tealeaves demand rising steadily both at home and abroad.But because mechanical operation is meticulous not, the tea quality of output is difficult to ensure, so drop into the mechanical processing quality of more energy research raising tealeaves, is very necessary.Tealeaves screening is by sieves, the foreign material such as the sandstone in tealeaves, dust to be separated.Tradition screening mode is all that artificial jitter filtering is screened, and efficiency is lower, and labor strength is large.Existing vibrations screening machine structure is more complicated, and each vibratory sieve all needs to arrange percussion mechanism, and manufacturing cost is higher, also cannot filter out the withered and yellow Lao Ye in tealeaves.Therefore need a kind of Tea screening machine, make it not only have that screening effeciency is high, screening accuracy is strong, also there is the features such as simple in structure, low cost of manufacture.

Utility model content

The utility model, on the basis of existing tealeaves screening technique, adopts the unique design of novelty, has proposed a kind of Tea screening machine.

The utility model adopts following technical scheme to solve existing issue.

, its primary structure comprises: screen frame, rocking bar, turning cylinder, frame, spring, fan, baffle plate, useless leaf groove, piano-wire screen, eccentric wheel, Connection Block.

Before and after the screen frame outside of described screening machine, be arranged with two rocking bars, rocking bar is hinged on eccentric wheel by turning cylinder, and during work, along with eccentric rotation, the two ends of screen frame alternately move up and down; Screen frame bottom is provided with as layer of steel wire sieve, and sieve density is less than standard tealeaves size.

In described screen frame, left end is provided with a fan, and during work, wind can level blow on the tealeaves on piano-wire screen surface, wind-force size can blow afloat withered and yellow leaf, can not blow standard weights tealeaves and be as the criterion; Screen frame right-hand member is provided with a baffle plate, inside baffle plate, bottom is provided with a useless leaf groove, described two ends, screening frame bottom left and right are arranged with two springs, the other end of spring is separately fixed on the frame both sides of screening machine, described eccentric wheel is hinged on Connection Block, and is fixed in frame by Connection Block.

The beneficial effects of the utility model: a kind of Tea screening machine the utility model proposes, its structural principle is simple, and design is unique ingenious.Screen frame is hinged on eccentric wheel by rocking bar and turning cylinder, and during work, along with eccentric rotation, the two ends of screen frame alternately move up and down, and makes the constantly tossed and upset of tealeaves in screen frame, thereby screens out impurity wherein; Meanwhile, the fan in work can blow away the lighter withered and yellow Lao Ye of weight in tealeaves, and utilizes baffle plate to block Lao Ye, makes it fall into useless leaf groove.Utilize this screening machine can improve efficiency and the precision of tealeaves screening; The spring at screen frame two ends when supporting screen frame, can effectively reduce screen frame to the impact of frame, extend service life of screening machine, be adapted at promoting the use of in Tea Production apparatus field.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a kind of Tea screening machine, its primary structure comprises: screen frame 1, rocking bar 2, turning cylinder 3, frame 4, spring 5, fan 6, baffle plate 7, useless leaf groove 8, piano-wire screen 9, eccentric wheel 10, Connection Block 11.

As shown in Figure 1 and Figure 2, be arranged with two rocking bars 2, and be hinged on eccentric wheel 10 by turning cylinder 3 before and after screen frame 1 outside of screening machine, during work, along with the rotation of eccentric wheel 10, the two ends of screen frame 1 alternately move up and down; Screen frame 1 bottom is provided with as layer of steel wire sieve 9, and sieve density is less than standard tealeaves size, and tealeaves during work in screen frame 1 is tossed and upset constantly, thereby screens out impurity wherein.

As shown in Figure 1 and Figure 2, the interior left end of screen frame 1 is provided with a fan 6, and during work, wind can level blow on the tealeaves on piano-wire screen 9 surfaces, wind-force size can blow afloat withered and yellow leaf, can not blow standard weights tealeaves and be as the criterion; Screen frame 1 right-hand member is provided with a baffle plate 7, and baffle plate 7 bottoms, inner side are provided with a useless leaf groove 8, and work fan 6 can blow away the lighter withered and yellow Lao Ye of weight in tealeaves, and utilizes baffle plate 7 to block Lao Ye, makes it fall into useless leaf groove 8.

As shown in Figure 1, screen frame 1 two ends, left and right, bottom are arranged with two springs 5, and the other end of spring 5 is separately fixed on frame 4 both sides of screening machine, bullet, and 5 can effectively reduce the impact of 1 pair of frame 4 of screen frame when supporting screen frame 1.

As shown in Figure 1 and Figure 2, eccentric wheel 10 is hinged on Connection Block 11, and is fixed in frame 4 by Connection Block 11.
