Description

Technical Field

[0001] This utility model relates to the field of tea conveying technology, and in particular to a primary tea conveying device. Background Technology

[0002] Black tea gets its name from the red color of the tea soup and tea leaves after brewing. It belongs to the category of fully fermented tea and is made from the buds and leaves of the tea tree through typical processes such as withering, rolling, fermentation, and drying.

[0003] Currently, after black tea undergoes withering, rolling, fermentation, and drying processes, it needs to be sorted and packaged for storage and sale. In existing technology, after the black tea is taken out of the drying equipment, it needs to be transported to the sorting and packaging area via a conveyor system. Since the temperature of the black tea is high when it is taken out of the drying equipment, it needs to be cooled during the transportation process in order to evaporate excess moisture, promote aroma release and improve taste, extend shelf life and stabilize quality, and optimize subsequent processing steps. This step is indispensable in tea processing and is of great significance for improving tea quality and market competitiveness.

[0004] When existing black tea is spread out and cooled on a conveyor belt, it is usually cooled naturally. Since the spread-out black tea has a certain thickness, the top layer of black tea on the conveyor belt has the largest contact area with the air. However, the air around the black tea in contact with the conveyor belt is thin, and the air flow rate around it is much lower than that around the top layer of black tea. As a result, the black tea in contact with the conveyor belt cannot be completely cooled before being bagged, which reduces the taste and quality of the black tea and significantly shortens its shelf life.

[0005] To overcome the above deficiencies, this utility model provides a primary tea processing conveying device, which aims to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a primary tea processing conveying device, comprising:

[0007] The conveyor belt has multiple conveyor boxes fixedly installed on its upper and lower sides along its own rotation direction;

[0008] The drive shaft is rotatably installed in the inner cavity of the conveyor box, and multiple flipping plates for turning the tea leaves are fixedly installed in a ring on the outer wall of the drive shaft.

[0010] The guide rail is fixedly installed on the top of the conveyor belt. One end of the air duct extends to the outside of the conveyor box and is located between the guide rail and the conveyor box. Multiple air supply pipes are fixedly installed horizontally on the end of the guide rail away from the conveyor box. An air pump is fixedly installed on one side of the conveyor belt. The air outlet of the air pump is fixedly connected to one end of the multiple air supply pipes through a conduit.

[0011] As a further description of the above technical solution:

[0012] The conveyor box is curved away from its own open end inner wall, and the straight-line distance between the middle of the conveyor box's inner wall away from its own open end and the bottom of the drive shaft is the same as the height of the tilting plate.

[0013] As a further description of the above technical solution:

[0014] The drive shaft has a cavity inside that is compatible with the air duct, and the outer wall of the drive shaft has multiple through holes that communicate with the cavity in a ring. The end of the air outlet that is away from the air duct passes through the through holes and extends to the outside of the drive shaft.

[0015] As a further description of the above technical solution:

[0016] The driving component includes a rotating shaft and a driving gear.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, when the conveyor belt rotates, the drive shaft rotates under the action of the drive component, and multiple flipping plates push the black tea on the top layer to the bottom layer, while flipping the black tea on the bottom layer to the top layer.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 One embodiment of this utility model is a primary tea processing conveying device, comprising:

[0031] The conveyor belt 1 has multiple conveyor boxes 5 fixedly installed on its upper and lower sides along its rotation direction. The dried black tea can be transported through the multiple conveyor boxes 5 to facilitate the sorting and packaging of the black tea. After the conveyor box 5 containing black tea moves to the bottom of the conveyor belt 1, the black tea inside the conveyor box 5 falls to the outside of the conveyor box 5 under the action of gravity, so as to empty the black tea inside the conveyor box 5. The dried black tea can be continuously transported through the conveyor boxes 5. This is the prior art and will not be described in detail here.

[0032] The drive shaft 2 is rotatably installed in the inner cavity of the conveyor box 5, and multiple flipping plates 3 for turning the tea leaves are fixedly installed in a ring on the outer wall of the drive shaft 2. The outside of the conveyor belt 1 is provided with a drive component for the rotation of the drive shaft 2. As the conveyor belt 1 continues to rotate, the drive shaft 2 located at the top of the conveyor belt 1 rotates continuously under the action of the drive component. At this time, the multiple flipping plates 3 can push the black tea at the top layer to the bottom layer, and at the same time flip the black tea at the bottom layer to the top layer, so as to achieve the purpose of continuous turning of the black tea inside the conveyor box 5, which is conducive to the rapid cooling of the black tea inside the conveyor box 5.

[0033] To prevent the tea from being squeezed and broken when the flipping plate 3 rotates, causing the tea located between the bottom of the drive shaft 2 and the bottom of the inner cavity of the conveying box 5, the inner wall of the conveying box 5 away from its opening is bent. The straight-line distance between the middle of the inner wall of the conveying box 5 away from its opening and the bottom of the drive shaft 2 is the same as the height of the flipping plate 3. As the drive shaft 2 rotates, the ends of multiple flipping plates 3 away from the drive shaft 2 alternately fit against the bottom side wall of the inner cavity of the conveying box 5. This prevents a large gap between the end of the flipping plate 3 away from the drive shaft 2 and the inner wall of the conveying box 5, which would cause the tea located between the bottom of the drive shaft 2 and the bottom of the inner cavity of the conveying box 5 to be squeezed and broken, thus ensuring the quality of the tea.

[0034] The air duct 4 is fixedly installed inside the drive shaft 2, and multiple air outlets 12 are fixedly installed in a ring on the outer wall of the air duct 4. The drive shaft 2 has a cavity that matches the air duct 4. In actual production, the air duct 4 can be installed inside the drive shaft 2 through the cavity that matches it.

[0035] The outer wall of the drive shaft 2 has multiple through holes that communicate with the chamber in a ring. The end of the air outlet 12 away from the air guide pipe 4 passes through the through hole and extends to the outside of the drive shaft 2. The ring-shaped through holes are arranged in multiple rows along the axial direction of the drive shaft 2. The number of through holes and the number of air outlets 12 are the same and correspond one-to-one, so that one end of the multiple air outlets 12 can pass through the multiple through holes and extend to the outside of the drive shaft 2.

[0036] Multiple flip plates 3 and multiple air outlets 12 are staggered. When the flip plate 3 flips the black tea, the flipped black tea is located between two flip plates 3, so that the bottom layer of black tea between the two flip plates 3 can contact one end of the air outlet 12.

[0037] Multiple air outlets 12 extend from the end of the air duct 4 to the outside of the drive shaft 2. The guide rail 9 is fixedly installed on the top of the conveyor belt 1. The end of the air duct 4 extending to the outside of the conveyor box 5 is located between the guide rail 9 and the conveyor box 5. When the conveyor box 5 located at the top of the conveyor belt 1 moves, the end of the air duct 4 extending to the outside of the conveyor box 5 moves through one end of the guide rail 9 to the inside of the guide rail 9. Before the conveyor box 5 located at the top of the conveyor belt 1 moves to the outside of the guide rail 9 through the other end of the guide rail 9, so as to facilitate the continuous movement of the conveyor box 5.

[0038] Multiple air supply pipes 8 are fixedly installed horizontally at the end of the guide rail 9 away from the conveyor box 5. An air pump 7 is fixedly installed on one side of the conveyor belt 1. The air outlet of the air pump 7 is fixedly connected to one end of the multiple air supply pipes 8 through a duct. When the air pump 7 is started, the surrounding air enters the interior of the multiple air supply pipes 8 through the duct through the air inlet, and then enters the interior of the guide rail 9 through the air outlet of the air supply pipes 8. This speeds up the flow of air around one end of the air duct 4 into the interior of the air duct 4. The air inside the air duct 4 flows through multiple air outlets 12 to the space between the two flip plates 3, thereby increasing the air flow rate around the bottom layer of black tea between the flip plates 3. This allows the black tea inside the conveyor box 5 to be completely cooled before packaging, improving the taste and quality of the black tea and greatly extending its shelf life.

[0039] The driving component includes a rotating shaft 10 and a driving gear 11. The middle of both ends of the driving shaft 2 is fixedly installed with rotating shafts 10 that are rotatably connected to the inner wall of the conveyor box 5. The end of the rotating shaft 10 closest to the guide rail 9 extends to the outside of the conveyor box 5. The driving gear 11 is fixedly sleeved on the outer wall of the rotating shaft 10 extending to the outside of the conveyor box 5. The top of the conveyor belt 1 is fixedly installed with a rack plate 6 that engages with the driving gear 11. After the end of the air duct 4 extending to the outside of the conveyor box 5 moves to the inside of the guide rail 9 through the guide rail 9, the outer wall of the driving gear 11 engages with the top of the rack plate 6. As the conveyor belt 1 moves continuously, the driving gear 11 rotates under the action of the rack plate 6, causing the rotating shaft 10 that is sleeved with the driving gear 11 to rotate, thereby providing a power source for the rotation of the driving shaft 2 and improving the convenience of the rotation of the driving shaft 2.

[0040] One end of the rotating shaft 10 extending to the outside of the conveyor box 5 is provided with an insertion hole. One end of the air guide pipe 4 passes through the insertion hole and extends to the outside of the conveyor box 5, which can ensure that the rotation centers of the drive shaft 2, the rotating shaft 10 and the air guide pipe 4 are on the same horizontal line, and can ensure that one end of the air guide pipe 4 can smoothly enter the interior of the guide rail 9 and move stably inside the guide rail 9.

[0041] Supports are symmetrically installed on both sides of the conveyor belt 1. The top of one of the supports is fixedly connected to the guide rail 9 and the bottom of the rack plate 6. The support not only supports both ends of the conveyor belt 1 to improve the stability of the conveyor belt 1 rotation, but also supports the bottom of the guide rail 9 and the rack plate 6 to improve the stability of the guide rail 9 and the rack plate 6.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
