Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the present invention, the terms "upper", "lower", "left", "right", "middle" and "one" are used for clarity of description, but not for limiting the range of the present invention, and the relative relationship changes or adjustments without substantial technical changes should be regarded as the scope of the present invention.

Referring to fig. 1-4, a tea leaf screening device comprises a screening box 1, wherein discharge ports are symmetrically formed in the top end of the screening box 1, an assembly cavity 2 is formed in an equal division position inside the screening box 1, a first fixing block 3 is fixedly installed on the inner wall of the assembly cavity 2 close to the lower end, a sliding column 5 is slidably installed on the equal division position of the first fixing block 3 through a first spring 4, the sliding column 5 is controlled to slide through a driving device, the driving device comprises a switch type reluctance motor 16 and a cam 17, the switch type reluctance motor 16 is fixedly connected to the inner wall of the screening box 1, the cam 17 is fixedly sleeved on an output shaft of the switch type reluctance motor 16, a convex end of the cam 17 is in contact with the sliding column 5, an output shaft of the switch type reluctance motor 16 rotates to drive the cam 17 fixedly sleeved with the cam 17 to rotate, and accordingly the convex end of the cam 17 discontinuously extrudes the bottom end of the sliding column 5 when rotating, so that the sliding column 5 slides up and down on the first fixing block 3, a second fixing block 6 is fixedly sleeved at one end of the sliding column 5 departing from the first fixing block 3, and the two ends of the second fixing block 6 are connected with the clamping piece through a first supporting device.

Each first supporting device comprises a third fixing block 8, a cross rod 9 and a second spring 10, the third fixing block 8 is fixedly connected to the inner wall of the assembly cavity 2, the third fixing block 8 is connected with a hollow column 11 through a support, a disc is arranged at one end of the cross rod 9, which is arranged inside the hollow column 11, one end of the second spring 10 is fixedly connected to the inner wall of the hollow column 11, the other end of the second spring is fixedly connected to the disc at one end of the cross rod 9, the other end of the cross rod 9 is rotatably connected with a clamping piece, the force generated when the second fixing block 6 and the first sieve plate 7 vibrate up and down is driven by the sliding column 5 due to the extrusion of a cam 17 and the elasticity of the first spring 4 are mainly balanced, so that the sliding column 5 can effectively act on the first sieve plate 7, when the force is transmitted to the sliding column 5 from the cam 17, the sliding column 5 moves up and down, and the cross rod 9 rotatably connected with the clamping piece is driven to swing up and down, follow closely horizontal pole 9 passes to the effort and installs in hollow post 11 and the cover is pulled to hollow post 11 inner wall to second spring 10 on horizontal pole 9, because hollow post 11 deviates from the one end of horizontal pole 9 and is connected with third fixed block 8 through rotating the connection, so make the frequency that traveller 5 reciprocated slow down on the one hand, on the other hand avoids tealeaves in first sieve 7 too much to lead to the gross weight to be greater than the elasticity of first spring 4 and the effect of vibrations about can't realizing, clamping piece and 6 lateral wall fixed connection of second fixed block, traveller 5 deviates from the one end of first fixed block 3 and is located the first sieve 7 of top fixedly connected with of second fixed block 6.

The left side and the right side of the lower wall of the first sieve plate 7 are symmetrically connected with a second sieve plate 15 vertically downwards through support rods 14, the sieve nets on the two sides of the first sieve plate 7 and the corresponding sieve nets in the second sieve plate 15 are on the same vertical plane, the support rods 14 vertically downwards corresponding to four corners of the first sieve plate 7 connect the second sieve plate 15 with the first sieve plate 7, so that when the first sieve plate 7 vibrates up and down for screening, force can be exerted on the second sieve plate 15, thereby realizing secondary screening of tea leaves, the aperture of the sieve net in the first sieve plate 7 is larger than that of the sieve net in the second sieve plate 15, a collecting box 19 is arranged under the second sieve plate 15, mainly for ensuring that impurities in the tea leaves are removed more cleanly, the aperture of the first sieve plate 7 is just the longest length in the tea leaves, so that the large impurities in the tea leaves can be filtered in one step of screening, the aperture size of second sieve 15 is minimum in the tealeaves length, prevents that the in-process of screening from falling the waste of good tealeaves, and will drop out from second sieve 15 and get into collecting box 19 than the impurity that tealeaves is little in, wait that whole screening is good after take out impurity pour can, four angles of first sieve 7 all through second strutting arrangement and screening case 1 inner wall connection.

The second strutting arrangement includes third spring 12, support column 13 and mounting groove 18, mounting groove 18 fixed connection is on screening case 1 inner wall, the one end fixed connection of third spring 12 is in the cell wall of mounting groove 18, the other end fixed connection of third spring 12 is on one end of support column 13, the other end of every support column 13 and the corresponding one corner fixed connection of first sieve 7, when upwards extrudeing through support column 13 from first sieve 7 as the strength, support column 13 extrudees to the third spring 12 rather than fixed connection this moment, play the ascending extruded buffering of effort on the one hand, on the other hand can let first sieve 7 also can have some slight vibrations from top to bottom when power slowly reduces, but all vibrations begin to end for the time of cam 17 rotation a week.

The utility model discloses in, the user is when using the device, at first open drive arrangement's power, when reaching the traveller 5 from cam 17 with exerting force on, thereby extrude first spring 4 this moment and make traveller 5 drive first sieve 7 upward movement, first spring 4 extrudees between second fixed block 6 and first fixed block 3 simultaneously, the first strutting arrangement of cooperation work promotes the upper and lower vibrations that traveller 5 drove first sieve 7 and second sieve 15 this moment, thereby obtain carrying out effectual screening to tealeaves, all vibrations effort from beginning to the end are the time of cam 17 rotation a week among the drive arrangement this moment, just can realize that cam 17 does not extrude once traveller 5 and just can produce the effect of vibrations from top to bottom this moment, and reduce the off-time between last vibrations effect and the next vibrations effect.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
