DETAILED DESCRIPTION OF THE EMBODIMENTS
The technical solutions in the embodiments of the present in- vention will be clearly and completely described below in combina- tion with the accompanying drawings in the embodiments of the pre- sent invention. Apparently, the embodiments described are merely some rather than all of the embodiments of the present invention.
Based on the embodiments in the present invention, all other em- bodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
As shown in FIG. 1-FIG. 7, the present invention provides a tea winnowing machine with double air ducts, including: a primary air box 1, wherein a screening wind field perpen- dicular to a material falling direction is constructed in the pri- mary air box 1 by means of an axial flow fan 3 arranged on one side of the primary air box 1, a feed hopper 4 is arranged at a top of the primary air box 1, and the feed hopper 4 is arranged at a top of the primary air box 1 away from the axial flow fan 3; and a secondary air box 2 connected to a bottom of the primary air box 1, wherein a screening wind field perpendicular to a mate- rial falling direction is constructed in the secondary air box 2 by means of a centrifugal fan 14 arranged on one side of the sec- ondary air box 2; wherein a falling material collecting and transporting device 5 is arranged at a junction of the primary air box 1 and the sec- ond air box 2, and the falling material collecting and transport- ing device 5 is configured to collect a falling material screened in the screening wind field in the primary air box 1 and transport the falling material to a beginning end of the material falling direction of the secondary air box 2; and a screened material output device 6 is arranged at a bottom of the secondary air box 2.
According to the present invention, during specific work, tea leaves to be winnowed are put in the primary air box 1 by means of the feed hopper 4, and then the tea leaves entering the wind field are winnowed in the wind field constructed in the primary air box 1 by means of the axial flow fan 3. The process is coarse screen- ing. Of course, in the process, dust will be accumulated in a place close to the axial flow fan 3, sundries with large mass such as stones will be accumulated at the bottom of the feed hopper 4 directly facing the primary air box 1, the coarsely screened tea leaves will be distributed therebetween, and this area just covers the falling material collecting and transporting device 5. The tea leaves passing through the falling material collecting and trans- porting device 5 enter the secondary air box 2. Since the air cur- tain wind field constructed by the centrifugal fan 14 is used in the secondary air box 2, it is needed to transport the screened tea leaves by the falling material collecting and transporting de- vice 5 to the junction of the centrifugal fan 14 and the secondary air box 2 for material falling. The tea leaves are screened again in the wind field in the secondary air box 2, so that the screened tea leaves fall into the screened material output device 6.
Further, in order to improve the winnowing quality and effi- ciency of the tea leaves in the winnowing process, the primary air box 1 is internally provided with a plurality of primary tea re- taining plates 7, a material falling channel is formed between two adjacent primary tea retaining plates 7, and the falling material collecting and transporting device 5 is arranged below the plural- ity of primary tea retaining plates 7.
The secondary air box 2 is internally provided with a plural- ity of secondary tea retaining plates 8, a material screening channel is formed between two adjacent secondary tea retaining plates 8, and the screened material output device 6 is arranged on a bottom wall of the secondary air box 2 below the plurality of secondary tea retaining plates 8.
The falling material collecting and transporting device 5 in- cludes a plurality of successively connected material receiving trough bodies 11, and feed inlets of the plurality of successively connected material receiving trough bodies 11 are in one-to-one correspondence to the plurality of material screening channels.
The screened material output device 6 includes a plurality of successively connected discharging notches 13, and the discharging notches 13 are in one-to-one correspondence to the material screening channels.
A transporting device 12 is arranged at a bottom of the fall- ing material collecting and transporting device 5 and includes a conveyor belt 121, a transmission bar 122 and a driving motor 123, and the driving motor 123, driving the transmission bar 122 to ro- tate, drives transmission of the conveyor belt 121 to collect a falling material screened in the screening wind field in the pri- mary air box 1 and transport the falling material to a beginning end of the material falling direction of the secondary air box 2.
Transmission rollers 124 are arranged on two ends of the transmission bar 122, and the conveyor belt 121 is connected with the transmission bar 122 between the two transmission rollers 124.
Further, since in the tea leave winnowing process, the tea leaves moves in a parabolic manner, rotating shafts 15 are ar- ranged in the middle portions of two ends of the primary tea re- taining plates 7 and the secondary tea retaining plates 8, and the primary tea retaining plates 7 are rotatably connected to an inner wall of the primary air box 1 by means of the rotating shafts 15.
Its objective lies in that angles of the primary tea retaining plates 7 and the secondary tea retaining plates 8 relative to the primary air box 1 and the secondary air box 2 can be adjusted, so that the feed inlets of the material receiving trough bodies 11 can be matched with the winnowing movement state of the tea leaves in the upper air cavities 16, and therefore, an ideal sorting re- sult is obtained in the material receiving trough bodies 11.
The secondary tea retaining plates 8 are rotatably connected to an inner wall of the secondary air box 2 by means of the rotat- ing shafts 15.
In the present invention, further, the screening wind field perpendicular to the material falling direction constructed in the primary air box 1 by means of the axial flow fan 3 includes upper air cavities 16 located in the plurality of primary tea retaining plates 7 and lower air cavities 17 located between the plurality of primary tea retaining plates 7 and the falling material col- lecting and transporting device 5.
An air inlet 18 is formed in an end of the primary air box 1 away from the axial flow fan 3, and the feed hopper 4 is installed at the top of the primary air box 1 close to the air inlet 18.
Further, the tea winnowing machine with double air ducts pro- vided by the present invention can be used for more refined tea leaf winnowing. Specifically, a material transferring port 19 is formed in the bottom of each of the material receiving trough bod- ies 11 and an opening and closing door assembly 20 for opening and closing the material transferring port 19 is arranged below the material receiving trough bodies 11, and the opening and closing door assembly 20 is configured to successively open the plurality of material transferring ports 19 and to close the previous mate- rial transferring port 19 while opening the later material trans- ferring port 19.
That is to say, the material transferring ports 19 of the ma- terial receiving trough bodies 11 are opened and closed succes- sively by means of the opening and closing door assembly 20, so that the tea leaves in the material receiving trough bodies 11 successively fall into the secondary air box 2. Therefore, the tea leaves in each of the material receiving trough bodies 11 are in- dependently winnowed in the secondary air box 2, so that the re- fined winnowing operation is achieved.
The opening and closing door assembly 20 includes an angle plate 201 matched with the material transferring port 19, and a telescopic pole 202 driving the angle plate 201 to be close to and away from the material transferring port 19, two ends of the angle plate 201 are embedded into the inner wall of the primary air box 1, a guide slot where the angle plate 201 moves up and down is formed in the inner wall of the primary air box 1, the telescopic pole 202 is arranged in the guide slot, and an output end of the telescopic pole 202 is connected with an end of the angle plate 201.
A longitudinal section of the angle plate 201 is in a shape of obtuse triangle, and a length of one waist is much greater than a length of the other waist; and the angle plate 201 faces the air inlet 18 from a plane formed by the longer waist, which aims to guide the wind field in the lower air cavity 17.
Further, in the present invention, an air guantity adjusting assembly 21 is arranged at the air inlet 18, and the air quantity adjusting assembly 21 is configured to adjust air quantity distri- bution in the upper air cavities 16 and the lower air cavities 17 of the axial flow fan 3. Its major objective lies in that when the angular plate 201 needs to be matched with the material transfer- ring port 19 to seal the material transferring port 19, the air quantity adjusting assembly 21 decreases the air inlet of the up- per air cavity 16, and the air input of the upper air cavity 16 is decreased. Thus, the air quantity of the lower air cavity 17 en- ters the upper air cavity 16 by means of the material transferring port 19 so as to play an upward winnowing and cleaning role to the tea leavers entering the material receiving trough body 11, so that an error that the winnowed tea leaves in the upper air cavity 16 are not winnowed and fall into the material receiving trough body 11 as a result of adhesion can be avoided. Meanwhile, the tea leaves are prevented from being accumulated at the material trans- ferring port 19, so that the angular plate 201 quickly seals the material transferring port 19, and the tea leaves are prevented from being clamped and broken when the material transferring port is sealed. When the angular plate 201 seals the material transfer- ring port 19, the air quantity adjusting assembly 21 closes or de- creases the air quantity of the lower air cavity 17. The upper air cavity 16 enters a normal winnowing mode, and in an initial state, the angular plate 201 is hermetically connected with the material transferring port 19.
When it is needed to perform efficient coarse screening, the angular plate 201 can be directly opened in the initial state of screening. That is to say, the material transferring port 19 is in a state where materials fall into the secondary air box 2 all the time. At the time, the wind filed in the upper air cavity 16 pre- liminarily screens the tea leaves, and the lower air cavity 17 screens the preliminarily screened tea leaves again.
It is further to be noted that the right front and the tail of the secondary air box 2 are fixed by means of a first movable frame and a second movable frame. An air guide pipe is arranged at the front end of the secondary air box 2, the air guide pipe is fixed to the front end of the secondary air box 2 by means of the frame and is connected with the secondary air box 2, and the air guide pipe is internally provided with the centrifugal fan 14.
The driving motor 123 is a three-phase asynchronous alternat- ing current motor, with a specification of YD112M-6, a rated power of 2.2 KW and a terminal output rotating speed of 960 (r/min).
The axial flow fan is a T35-11 type axial flow fan, with a specification of T35-1-2.8, an output rotating speed of 2900 (r/min), an air quantity of 3202 m’/h, a motor model of YSF-6300 and a rated power of 0.25 KW.
