Description

Technical Field

[0001] The invention belongs to the technical field of tea processing, and more specifically, particularly relates to a multi-layer sorting machine for tea processing. Background Art

[0002] Tea refers to the leaves and buds of the tea tree, which is a perennial woody plant belonging to the Theaceae family. Taking common tea as an example, tea usually needs to go through the steps of picking, sorting, withering, rolling, fermentation, and drying. Due to the differences in the quality of tea leaves of different sizes, shapes, and degrees of completeness, for example, complete tea leaves with plump buds usually have better taste and aroma than broken tea leaves. Sorting can distinguish high-quality tea leaves (such as premium tea, which often has complete buds and high uniformity) from general-quality tea leaves, thereby pricing them according to quality to meet the needs of different consumers. Sorting can also make each batch of tea relatively consistent in appearance, size, color, etc., so that consumers can get a relatively stable quality experience when purchasing the same type of tea.

[0003] At present, the existing device (such as announcement number: CN112007856B) discloses a tea sorting device and a method of using the same. The device screens tea leaves of different volumes by setting a plurality of screens with apertures from large to small. The rotation of the screens causes the tea leaves to generate centrifugal force and enter the collection box from the inclined pipe. At the same time, gravity is used to achieve layered screening through the upper and lower multi-level screens with apertures from large to small. The present invention effectively replaces manual screening, is conducive to the mechanized development of the tea industry, has the advantages of being able to prepare the volume on demand and being suitable for the needs of various production capacities, and has a simple structure and simple operation, and is suitable for use by small and micro tea processing enterprises or tea farmers. At the same time, the device introduces a speed change system, which can improve work efficiency according to actual needs.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the device sets a plurality of screens in the shell to realize layered screening with four screens from large to small, but this sorting method is easy to cause some of the currently falling tea leaves to fall directly from the current inclined pipe without being screened when the tea leaves fall between the screens, which leads to insufficient sorting effect. Summary of the invention

[0008] The reciprocating multi-layer sorting structure includes a first sorting layer, a second sorting layer and a third sorting layer, the first sorting layer is located above the second sorting layer, the third sorting layer is located above the second sorting layer, a first side end connecting cover is fixedly installed between the first sorting layer and the second sorting layer, a second side end connecting cover is fixedly installed between the second sorting layer and the third sorting layer, a first discharge hopper is provided on the side wall of the first sorting layer, a second discharge hopper is provided on the side wall of the second sorting layer, a third discharge hopper is provided on the side wall of the third sorting layer, a cover plate is fixedly installed on the upper end of the third discharge hopper, the first discharge hopper, the second discharge hopper and the third discharge hopper are all in different directions, and a second sorting hole group is provided inside the second sorting layer.

[0009] Preferably, a first sorting hole group is provided inside the third sorting layer, and a first reciprocating transport pipeline is fixedly installed at the lower end of the second sorting layer. The first reciprocating transport pipeline is located on the outside of the first sorting hole group, and the connection point of the first reciprocating transport pipeline on the second sorting layer is located on one side of the second discharge hopper.

[0010] Preferably, a second reciprocating transport pipe is fixedly installed at the lower end of the third sorting layer, the second reciprocating transport pipe is located on the outside of the second sorting hole group, the connection point of the second reciprocating transport pipe on the third sorting layer is located on one side of the third discharge hopper, and a first oblique baffle is provided on the inner side of the second sorting layer.

[0011] Preferably, the first inclined baffle is located below the second reciprocating transport pipeline, a second inclined baffle is provided on the inner side of the third sorting layer, a main feed hopper is fixedly installed on the upper end of the third sorting layer, the second inclined baffle is located on the outer side of the main feed hopper, and a plurality of columns are symmetrically fixedly installed on the upper end of the bracket.

[0012] Preferably, each of the pillars is located on both sides of the first sorting layer, the second sorting layer and the third sorting layer, and a plurality of springs are fixedly installed on the side walls of each of the pillars, and each of the springs is respectively parallel to the first sorting layer, the second sorting layer and the third sorting layer, and each of the springs is respectively fixedly installed to the first sorting layer, the second sorting layer and the third sorting layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, the first sorting layer, the second sorting layer and the third sorting layer are respectively arranged on the vibration base, so that the first sorting layer, the second sorting layer and the third sorting layer are stacked, so that the first sorting layer, the second sorting layer and the third sorting layer can perform multi-stage sorting on the tea leaves from top to bottom, thereby improving the sorting rate.

[0015] In the present invention, by installing the first side end connecting cover and the second side end connecting cover between the first sorting layer and the second sorting layer and between the second sorting layer and the third sorting layer respectively, it can be avoided that when the material is transported on the second sorting layer and the first sorting layer respectively through the first reciprocating transport pipe and the second reciprocating transport pipe, the tea leaves are not thrown out when sliding due to the vibration of the vibrating base, thereby improving reliability.

[0016] In the present invention, by arranging a second reciprocating transport pipeline between the second sorting layer and the third sorting layer, tea leaves that do not conform to the second sorting hole group on the third sorting layer can be screened, so that the tea leaves that do not conform to the third sorting layer can fall on the second side end connecting cover on the second sorting layer through the second reciprocating transport pipeline, thereby ensuring that the materials screened by the second sorting layer are screened throughout the process, further reducing the possibility of unqualified screening.

[0017] In the present invention, by arranging a second reciprocating transport pipeline between the second sorting layer and the third sorting layer, tea leaves that do not conform to the second sorting hole group on the third sorting layer can be screened, so that the tea leaves that do not conform to the third sorting layer can fall on the second side end connecting cover on the second sorting layer through the second reciprocating transport pipeline, thereby ensuring that the materials screened by the second sorting layer are screened throughout the process, further reducing the possibility of unqualified screening.

[0018] In the present invention, by respectively arranging the second inclined baffle bar and the first inclined baffle bar on the second sorting layer and the third sorting layer, the material transported through the main feed hopper and the material transported through the second reciprocating transport pipeline can be blocked when entering the second sorting layer and the third sorting layer for transportation and sorting, so that the material on the second sorting layer and the third sorting layer can be fully spread out, so that the material can be fully sorted with the first sorting hole group and the second sorting hole group on the second sorting layer and the third sorting layer, thereby greatly improving the overall sorting rate of the device.

[0019] In the present invention, a plurality of columns are arranged on the bracket, and a plurality of springs are arranged on the columns, and are respectively fixedly installed with each first sorting layer, the second sorting layer and the third sorting layer, so that when the vibration base is turned on, the vibration base as a whole transmits the vibration force to the first sorting layer, the second sorting layer and the third sorting layer through the connecting plate, thereby making the first sorting layer, the second sorting layer and the third sorting layer vibrate. At the same time, since the springs on the columns are respectively connected with the first sorting layer, the second sorting layer and the third sorting layer, the springs on the columns are adaptively irregularly stretched and contracted, so that the reciprocating multi-layer sorting structure can be limited in multiple directions and regions, avoiding excessive center of gravity, which causes the third sorting layer to vibrate violently and leads to a reduction in service life, thereby improving reliability.

DETAILED DESCRIPTION

[0028] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] See also Figure 1 - Figure 7 The present invention provides a multi-layer sorting machine for tea processing, comprising a bracket 11, a vibration base 12 is fixedly installed on the upper end of the bracket 11, a connecting plate 13 is provided on the upper end of the vibration base 12, and a screw 14 is threadedly installed between the connecting plate 13 and the vibration base 12;

[0030] The upper end of the screw 14 is provided with a reciprocating multi-layer sorting structure;

[0031] The reciprocating multi-layer sorting structure includes a first sorting layer 15, a second sorting layer 16 and a third sorting layer 17. The first sorting layer 15 is located above the second sorting layer 16, and the third sorting layer 17 is located above the second sorting layer 16. By respectively arranging the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 on the vibration base 12, the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 are stacked, so that the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 perform multi-stage sorting on the tea leaves from top to bottom, thereby improving the sorting rate.

[0032] A first side end connecting cover 27 is fixedly installed between the first sorting layer 15 and the second sorting layer 16, and a second side end connecting cover 28 is fixedly installed between the second sorting layer 16 and the third sorting layer 17. By respectively installing the first side end connecting cover 27 and the second side end connecting cover 28 between the first sorting layer 15 and the second sorting layer 16 and between the second sorting layer 16 and the third sorting layer 17, it is possible to avoid the tea leaves being thrown out when sliding due to the vibration of the vibrating base 12 when the material is transported on the second sorting layer 16 and the first sorting layer 15 respectively through the first reciprocating transport pipe 25 and the second reciprocating transport pipe 26, thereby improving reliability.

[0033] A first discharge hopper 18 is provided on the side wall of the first sorting layer 15, a second discharge hopper 19 is provided on the side wall of the second sorting layer 16, and a third discharge hopper 21 is provided on the side wall of the third sorting layer 17. A cover plate 22 is fixedly installed on the upper end of the third discharge hopper 21. The first discharge hopper 18, the second discharge hopper 19 and the third discharge hopper 21 all have different directions. Since the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 are stacked and are all vibrated by the vibration base 12 under the first sorting layer 15, the third sorting layer 17 will shake more violently than the first and second discharge hoppers 18 and 19 due to excessive vibration. By arranging the cover plate 22 on the third discharge hopper 21, it can be avoided that when the third discharge hopper 21 discharges materials, the material falls on the first and second discharge hoppers 18 and 19 due to excessive shaking, thereby affecting the sorting quality.

[0034] A second sorting hole group 24 is provided inside the second sorting layer 16, a first sorting hole group 23 is provided inside the third sorting layer 17, a first reciprocating transport pipe 25 is fixedly installed at the lower end of the second sorting layer 16, the first reciprocating transport pipe 25 is located outside the first sorting hole group 23, and the connection point of the first reciprocating transport pipe 25 on the second sorting layer 16 is located on one side of the second discharge hopper 19, a second reciprocating transport pipe 26 is fixedly installed at the lower end of the third sorting layer 17, the second reciprocating transport pipe 26 is located outside the second sorting hole group 24, and the second reciprocating transport pipe The connection point of the channel 26 on the third sorting layer 17 is located on one side of the third discharge hopper 21. By arranging a second reciprocating transport pipeline 26 between the second sorting layer 16 and the third sorting layer 17, the tea embryos that do not meet the second sorting hole group 24 on the third sorting layer 17 can be screened, so that the tea embryos that do not meet the third sorting layer 17 can fall on the second side end connecting cover side of the second sorting layer 16 through the second reciprocating transport pipeline 26, thereby ensuring that the materials screened by the second sorting layer 16 are fully screened, further reducing the possibility of unqualified screening.

[0035] A first oblique baffle 29 is provided on the inner side of the second sorting layer 16, and the first oblique baffle 29 is located below the second reciprocating transport pipe 26. A second oblique baffle 31 is provided on the inner side of the third sorting layer 17. A main feed hopper 32 is fixedly installed on the upper end of the third sorting layer 17, and the second oblique baffle 31 is located on the outer side of the main feed hopper 32. By respectively arranging the second oblique baffle 31 and the first oblique baffle 29 on the second sorting layer 16 and the third sorting layer 17, the materials transported through the main feed hopper 32 and the materials transported through the second reciprocating transport pipe 26 can be blocked when entering the second sorting layer 16 and the third sorting layer 17 for transportation and sorting, so that the materials on the second sorting layer 16 and the third sorting layer 17 can be fully spread out, so that the materials can be fully sorted with the first sorting hole group and the second sorting hole group 24 on the second sorting layer 16 and the third sorting layer 17, thereby greatly improving the overall sorting rate of the device.

[0036] A plurality of columns 33 are symmetrically fixedly installed on the upper end of the bracket 11, each of which is located on both sides of the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17, and a plurality of springs 34 are fixedly installed on the side wall of each column 33, each spring 34 is respectively parallel to the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17, and each spring 34 is respectively fixedly installed with the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17, by arranging a plurality of columns 33 on the bracket 11, and arranging a plurality of springs 34 on the columns 33, and respectively fixing them with each of the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17, so that the vibration When the moving base 12 is turned on, the vibration base 12 as a whole transmits the vibration force to the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 through the connecting plate 13, thereby causing the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 to vibrate. At the same time, since the springs 34 on the columns 33 are respectively connected to the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17, the springs 34 on the columns 33 are adaptively irregularly stretched and contracted, so that the reciprocating multi-layer sorting structure can be limited in multiple directions and regions, thereby avoiding excessive center of gravity that causes the third sorting layer 17 to vibrate violently, resulting in a reduction in service life, thereby improving reliability.

[0037] Working principle:

[0038] The first step is that when in use, the staff can first pour the tea embryos to be processed into the main feed hopper 32, and at the same time, the staff can turn on the vibration base 12, so that the vibration base 12 as a whole transmits the vibration force to the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 through the connecting plate 13, thereby making the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17 vibrate, and at the same time, because the springs 34 on the pillars 33 are respectively connected to the first sorting layer 15, the second sorting layer 16 and the third sorting layer 17, the springs 34 on the pillars 33 are adaptively irregularly stretched and contracted;

[0039] In the second step, due to the vibration of the third sorting layer 17, the tea leaves will be gradually discharged from the main feed hopper 32, and transported to the third discharge hopper 21 on the third sorting layer 17. The second oblique baffle 31 is provided, and the second oblique baffle 31 will block the tea leaves, so that the tea leaves are in a spread state and move to the third discharge hopper 21 on the third sorting layer 17. The third sorting layer 17 will screen the tea leaves that do not meet the second sorting hole group 24 on the third sorting layer 17, so that the tea leaves that do not meet the third sorting layer 17 are on the second reciprocating transport pipe 26. At the same time, the tea leaves that meet the second sorting hole group 24 on the third sorting layer 17 will be discharged through the third discharge hopper 21.

[0040] In the third step, when the tea leaves that do not meet the screening requirements of the second sorting hole group 24 on the third sorting layer 17 fall from the second sorting hole group 24, the tea leaves will fall into the second reciprocating transport pipe 26 between the second sorting layer 16 and the third sorting layer 17. Since the second reciprocating transport pipe 26 is inclined and the falling end is located on the side of the second sorting layer 16 away from the second discharge hopper 19, the tea leaves falling from any position on the third sorting layer 17 will slide through the second reciprocating transport pipe 26 to one end of the second side end connecting cover 28 and enter the second sorting layer 16. On, it can be ensured that the tea embryos sorted from the second sorting hole group 24 can be fully sorted again on the second sorting layer 16. At the same time, by setting the first inclined blocking bar 29, the tea embryos sliding down from the second reciprocating transport pipe 26 can be blocked when they fall on the second sorting layer 16 and move toward the second discharge hopper 19, so that the tea embryos falling on the second sorting layer 16 can be fully screened, so that the tea embryos falling on the second sorting layer 16 can be transported to the second discharge hopper 19 and transported through the second discharge hopper 19.

[0041] In the fourth step, most of the tea leaves will be sorted by the second sorting layer 16 and the third sorting layer 17 and transported through the third discharge hopper 21 and the cover plate 22 respectively. At the same time, the sorted tea leaves that do not conform to the first sorting hole group 23 on the second sorting layer 16 will eventually slide through the first reciprocating transport pipe 25 to the first sorting layer 15 near the first side end connecting cover 27, and finally be transported down from the side of the first discharge hopper 18.

Many modifications and variations will be apparent to those of ordinary skill in the art.
