[0001] This utility model relates to the field of tea processing technology, specifically to a pre-treatment device for fixing tea leaves. Background Technology

[0002] The main purpose of fixing tea leaves is to destroy and deactivate the oxidase activity in fresh leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols, evaporate some moisture, soften the tea leaves, make them easier to roll and shape, and at the same time remove the grassy smell and promote the formation of a good aroma.

[0003] Before the tea leaves are completely withered, they need to undergo pretreatment to achieve the purpose of withering. The working principle is to control the temperature, humidity and ventilation conditions so that the tea leaves lose water evenly in a suitable environment. However, when the existing pretreatment equipment is used to wither the tea leaves, the staff has to grab the processed tea leaves from the mesh plate for collection. Some tea leaves will remain on the mesh plate. Since the mesh plate is directly fixed in the tank and the surface is mesh-like, it is easy to make it difficult to pick up the remaining tea leaves.

[0023] 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.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A pre-treatment device for processing tea leaves, comprising:

[0026] The main body includes a withering trough 1, with a mesh plate 11 installed on the inner surface of the withering trough 1. A blower body 12 is fixedly connected to the surface of the withering trough 1, and a control panel 13 is fixedly connected to the surface of the blower body 12. When withering pretreatment is carried out before fixing the tea leaves, the tea leaves are first laid on the surface of the mesh plate 11, and then the blower body 12 blows hot air into the withering trough 1, so that the hot air penetrates the tea leaf layer laid on the mesh plate 11, causing the moisture in the tea leaves to vaporize and evaporate, making the leaves gradually soften, while taking away the moisture on the surface of the leaves, forming a water vapor pressure difference, which accelerates the evaporation of moisture inside the tea leaves. The blower body 12 and the control panel 13 are existing equipment and will not be described in detail here.

[0027] The lifting mechanism includes a frame plate 2, which is fixedly connected to the surface of the mesh plate 11. A hand handle 21 is fixedly connected to the surface of the mesh plate 11, and a rotating cylinder 22 is rotatably connected to the surface of the hand handle 21. A movable plate 23 is fixedly connected to the surface of the rotating cylinder 22. A threaded rod 24 is fixedly connected to the outer surface of the withering trough 1. A slot 25 is opened on the surface of the movable plate 23. A threaded cap 26 is installed on the surface of the threaded rod 24, and a grip 27 is fixedly connected to the surface of the threaded cap 26. The surface of the frame plate 2 is rectangular and its outer surface is aligned with the edge of the mesh plate 11. Under the action of the frame plate 2, the tea leaves placed on the mesh plate 11 can be blocked to prevent the tea leaves from falling off the edge when the staff moves the mesh plate 11 by lifting the hand handle 21.

[0028] Furthermore, there are two sets of hand levers 21 and threaded rods 24. The two sets of hand levers 21 are installed on both sides of the frame plate 2, and the two sets of threaded rods 24 are installed on both sides of the withering trough 1. Each set of hand levers 21 and threaded rods 24 consists of two. The surface of the hand lever 21 is U-shaped, and the threaded rod 24 is engaged with the surface of the slot 25. Under the action of the hand lever 21, the operator can move the mesh plate 11 and the frame plate 2 together by pulling the hand lever 21. Both ends of the hand lever 21 are fixed to the surface of the mesh plate 11. The threaded rod 24 is connected to the surface of the movable plate 23 through the slot 25, and the installation effect of the movable plate 23 and the threaded cap 26 can be achieved under the action of the threaded rod 24.

[0029] Furthermore, the inner diameter of the rotating drum 22 is the same as the diameter of the hand lever 21, and the surface of the movable plate 23 is "L" shaped. One end of the movable plate 23 is fixedly connected to the outer surface of the rotating drum 22, and the other end of the movable plate 23 is abutted against the outer surface of the withering trough 1. With the connection between the hand lever 21 and the rotating drum 22, the movable plate 23 can rotate around the hand lever 21 as the center. The connection between the hand lever 21, the rotating drum 22 and the movable plate 23 can achieve the connection effect between the mesh plate 11 and the withering trough 1.

[0030] Furthermore, one end of the threaded rod 24 is fixedly connected to the outer surface of the withering trough 1, and the other end of the threaded rod 24 is threadedly connected to the inner surface of the threaded cap 26. The threaded cap 26 abuts against the surface of the movable plate 23. Two sets of gripping rods 27 are provided, and the two sets of gripping rods 27 are installed on both sides of the threaded cap 26. With the connection of the threaded rod 24, the slot 25, and the threaded cap 26, the movable plate 23 can be limited and fixed on the surface of the withering trough 1, and the mesh plate 11 can be limited and fixed on the inner surface of the withering trough 1. The outer diameter of the threaded cap 26 is larger than the width of the slot 25. Under the action of the two sets of gripping rods 27, the operator can rotate it to move the threaded cap 26 together.

[0031] Furthermore, the surface of the control panel 13 is provided with a protective mechanism, which includes a cover plate 3. The cover plate 3 is movably connected to the surface of the blower body 12. The surface of the blower body 12 is fixedly connected to a mounting plate 31. The outer surface of the cover plate 3 is fixedly connected to a rotating block 32 and a movable block 34. The surface of the mounting plate 31 is provided with a rotating hole 33 and a sliding groove 35. The size of the cover plate 3 is larger than the size of the control panel 13. Under the action of the cover plate 3, it can cover the control panel 13 and play a protective role. Both the cover plate 3 and the mounting plate 31 are made of transparent and visible material.

[0032] Furthermore, there are two sets of mounting plates 31 and rotating blocks 32. The two sets of mounting plates 31 are abutted and connected to both sides of the cover plate 3, and the two sets of rotating blocks 32 are fixedly connected to both sides of the cover plate 3. The rotating blocks 32 are rotatably connected to the surface of the rotating holes 33. The diameter of the rotating holes 33 is the same as the diameter of the rotating blocks 32. The cover plate 3 can be installed through the two sets of mounting plates 31. With the connection between the rotating blocks 32 and the rotating holes 33, the cover plate 3 can rotate around the rotating blocks 32 as the center.

[0033] Furthermore, the cross-section of the movable block 34 is "T" shaped, and there are two sets of movable blocks 34. The two sets of movable blocks 34 are installed on both sides of the cover plate 3. The movable blocks 34 are slidably connected to the surfaces of the mounting plate 31 and the sliding groove 35. The surface of the sliding groove 35 is arc-shaped. The movable blocks 34, the mounting plate 31, and the sliding groove 35 generate a damping sliding effect, which allows the cover plate 3 to rotate to a certain angle under human action and stop without moving under the action of friction damping. At the same time, the arc of the sliding groove 35 will be centered on the rotating block 32.

[0034] Working principle: After the tea leaves are withered in the pretreatment device, the handles 27 on both sides of the withering trough 1 are rotated so that the threaded cap 26 moves on the surface of the threaded rod 24 through the thread and cancels the engagement with the movable plate 23. Then the threaded cap 26 is removed from the surface of the threaded rod 24. After that, the operator pulls the handles 21 on both sides towards the top of the withering trough 1 so that the screen plate 11 and the frame plate 2 are removed from the inside of the withering trough 1, thereby canceling the engagement between the threaded rod 24 and the slot 25. At this time, the screen plate 11 and the frame plate 2 are slowly tilted so that the tea leaves withered on the inner surface can be poured out from the tilted side and the tea leaves stuck in the mesh can be collected by patting the screen plate 11.

[0035] After the operator controls the blower body 12 by operating the control panel 13 and stops using it, the cover plate 3 is first moved towards the control panel 13 and slid between the two sets of mounting plates 31, so that the cover plate 3 rotates around the rotating block 32, and the rotating block 32 rotates on the surface of the rotating hole 33, so as to drive the movable block 34 to slide on the surface of the mounting plate 31 and the sliding groove 35 with damping. When the cover plate 3 is in close contact with the outer surface of the blower body 12, the cover plate 3 covers the top of the control panel 13, so that the cover plate 3 can protect the control panel 13 without obstructing the operator from observing the data on its surface.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
