Description

Technical Field

[0001] This invention relates to a tea processing apparatus, specifically a tea processing apparatus that avoids damage to tea leaves. Background Technology

[0002] Tea processing involves multiple steps, one of which is sun-drying, as seen in Pu-erh tea. Sun-drying occurs under the sun's heat and light, causing cell sap to flow and increase in concentration, initiating a series of chemical changes. These include the volatilization of some low-boiling-point aromatic substances, the hydrolysis of chlorophyll by enzymes in the tea leaves to produce phytol and phytyl-derived chlorophyll, and the oxidation of these by polyphenol oxidase to form unstable o-benzoic acid compounds. Further non-enzymatic oxidation occurs, and chlorophyll also begins to decompose and disappear under the influence of light and enzymes. The fresh leaves change from their initial green color to grayish-yellow, grayish-white (with white down on the buds), or grayish-brown. The sun-drying process is essentially the transformation of fresh leaves into raw tea leaves.

[0003] Existing techniques for sun-drying tea involve placing the tea leaves on a winnowing tray and directly exposing them to sunlight. This method has two drawbacks: firstly, it requires a thick layer of tea leaves spread out, resulting in insufficient drying of piled-up tea leaves. These under-dried leaves are easily damaged during later processing, hindering quality improvement. Secondly, this flat-surface drying method is highly dependent on the production area and manual labor, as the leaves are prone to damage during the stacking process, making it unsuitable for use. Therefore, this invention proposes a tea processing device to prevent tea leaf damage. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a tea processing device that avoids damage to tea leaves.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A tea processing device for preventing damage to tea leaves includes a base plate with a through hole at the center of its top surface. Several fixed rods are evenly distributed on the upper side of the base plate, each fixed rod having a slot at its top. A plug rod is fixedly connected to the center of the bottom surface of each fixed rod, and the plug rods are inserted into adjacent slots, with the lowest plug rod inserted into the through hole. A clamping mechanism is provided on each plug rod. Two connecting plates are symmetrically and movably connected to the sidewalls of the fixed rods. An arc-shaped plate is movably connected to the sidewalls of the connecting plates away from the fixed rods. Arc-shaped grooves are formed on the sidewalls of the two arc-shaped plates facing each other at the same height, and movable mechanisms are provided within these grooves. A horizontal bar is fixedly connected to the fixed rod between the two connecting plates, and several vertical rods are evenly distributed and fixedly connected to the bottom surface of the horizontal bar.

[0007] As a preferred embodiment of the present invention, the clamping mechanism includes a through hole, and the insertion rod has a through hole near its bottom end. A first spring is provided in the through hole, and both ends of the first spring are fixedly connected to movable rods. The movable rods are movably connected to the through hole. A plurality of slots are evenly distributed on the inner wall of the slot and the through hole. The end of the movable rod away from the first spring extends out of the through hole and is inserted into the slot.

[0008] As a preferred embodiment of the present invention, the movable mechanism includes a rotating shaft. Several rotating shafts are evenly distributed and movably connected on the inner sidewall of the arc-shaped groove. A round wheel is fixedly connected to the sidewall of each rotating shaft. The top end of one of the rotating shafts penetrates the top surface of the arc-shaped plate and is fixedly connected to a motor. The motor is fixedly connected to the top surface of the arc-shaped plate.

[0009] As a preferred embodiment of the present invention, the connecting plate has a side groove on the side near the fixing rod, a round shaft is fixedly connected in the side groove, a connecting block is movably connected to the side wall of the round shaft, the connecting block is fixedly connected to the fixing rod, and two second springs are sleeved on the side wall of the round shaft. One end of the two second springs is fixedly connected to the connecting block, and the other end of the second springs is fixedly connected to the inner wall of the side groove.

[0010] As a preferred embodiment of the present invention, a plurality of rollers are evenly distributed and fixedly connected on the bottom surface of the base plate.

[0011] As a preferred embodiment of the present invention, the connecting plates on two adjacent fixed rods are staggered at a counterclockwise 90-degree angle from top to bottom.

[0012] As a preferred embodiment of the present invention, the end of the movable rod away from the first spring is conical, the slot is conical, and the movable rod and the slot are matched to each other.

[0013] This invention provides a tea processing device that avoids damage to tea leaves, and has the following beneficial effects:

[0014] 1. This invention, by setting up a movable mechanism, an arc-shaped plate, a connecting plate, a horizontal bar, and a vertical bar, allows the winnowing basket containing tea leaves to be placed between two connecting plates during use, with the side wall of the winnowing basket inserted into the arc-shaped groove. The winnowing basket is clamped by the second spring on the connecting plate and the arc-shaped groove. Then, the motor drives the rotating shaft to rotate, which in turn drives the wheel to rotate. The wheel drives the winnowing basket to rotate back and forth continuously, and the vertical bar turns the tea leaves in the winnowing basket, resulting in a better sun-drying effect and avoiding damage to the tea leaves in later processing due to insufficient sun-drying.

[0015] 2. This invention comprises a base plate, a fixing rod, an insert rod, a slot, and a clamping mechanism. In use, the insert rod is inserted into the through hole on the base plate, and adjacent insert rods and slots are interlocked. Under the action of a first spring, the movable rod can be inserted into the slot, thus fixing the fixing rods. At this time, the connecting plate can be used to place the winnowing baskets in layers, which reduces the area for sun-drying, making it easier for later processing. On the other hand, it reduces excessive handling of the winnowing baskets, thereby further avoiding damage to the tea leaves, resulting in good performance. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figure 1-7 As shown, a tea processing device for preventing damage to tea leaves includes a base plate 1. A through hole 2 is formed at the center of the top surface of the base plate 1. Several fixing rods 3 are evenly distributed on the upper side of the base plate 1. Each fixing rod 3 has a slot 4 at its top. An insert rod 5 is fixedly connected to the center of the bottom surface of each fixing rod 3. The insert rods 5 are inserted into adjacent slots 4, with the lowest insert rod 5 inserted into the through hole 2. A clamping mechanism 6 is provided on the insert rod 5. The clamping mechanism 6 includes a through hole 13, which is formed near the bottom of the insert rod 5. A first spring 14 is provided inside the 3, and movable rods 15 are fixedly connected to both ends of the first spring 14. The movable rods 15 are movably connected to the through hole 13. Several slots 16 are evenly distributed on the inner wall of the slot 4 and the through hole 2. The end of the movable rod 15 away from the first spring 14 extends out of the through hole 13 and is inserted into the slot 16. This can realize the connection between two adjacent fixed rods 3 and between the bottom fixed rod 3 and the base plate 1, which facilitates the multi-layer sun-drying operation of tea leaves, reduces the damage to tea leaves caused by excessive operation, and has a good effect.

[0027] Among them, several rollers 24 are evenly distributed and fixedly connected on the bottom surface of the base plate 1, which facilitates the movement and operation of this device;

[0028] The movable rod 15 is conical at the end away from the first spring 14, and the slot 16 is conical. The movable rod 15 and the slot 16 are matched to each other to facilitate the clamping operation.

[0029] Two connecting plates 7 are symmetrically and movably connected to the side wall of the fixed rod 3. Arc plates 8 are movably connected to the side of the connecting plates 7 away from the fixed rod 3. Arc grooves 9 are opened on the side walls of the two arc plates 8 facing each other at the same height. A movable mechanism 10 is set in the arc groove 9. The movable mechanism 10 includes a rotating shaft 17. Several rotating shafts 17 are evenly distributed and movably connected to the inner side wall of the arc groove 9. A wheel 18 is fixedly connected to the side wall of each rotating shaft 17. The top of one of the rotating shafts 17 passes through the top surface of the arc plate 8 and is fixedly connected to a motor 19. The motor 19 is fixedly connected to the top surface of the arc plate 8. A horizontal bar 11 is fixedly connected to the fixed rod 3 between the two connecting plates 7. Several vertical bars 12 are evenly distributed and fixedly connected to the bottom surface of the horizontal bar 11. This can realize the reciprocating rotation operation of the tea in the winnowing basket and turn the tea over through the vertical bars 12. The tea drying effect is good, avoiding the possibility of damage to the tea in the later processing due to insufficient drying. The effect is good.

[0030] The connecting plate 7 has a side groove 20 near the fixed rod 3. A round shaft 21 is fixedly connected in the side groove 20. A connecting block 22 is movably connected to the side wall of the round shaft 21. The connecting block 22 is fixedly connected to the fixed rod 3. Two second springs 23 are sleeved on the side wall of the round shaft 21. One end of the two second springs 23 is fixedly connected to the connecting block 22, and the other end of the second springs 23 is fixedly connected to the inner wall of the side groove 20. The movement of the connecting plate 7 can fix the winnowing basket containing tea leaves, which is convenient for the stable sun-drying of tea leaves.

[0031] Among them, the connecting plates 7 on two adjacent fixed rods 3 are staggered at 90 degrees counterclockwise from top to bottom, which makes the sun-drying effect better.

[0032] Working principle: In use, this invention first selects an appropriate number of fixing rods 3, then moves the base plate 1 and the fixing rods 3 together to a suitable position. Next, the insert rod 5 on the fixing rod 3 is inserted into the through hole 2 on the base plate 1. Under the action of the first spring 14, the movable rod 15 is inserted into the slot 16 on the inner wall of the through hole 2, achieving positioning and fixing between the fixing rod 3 and the base plate 1. As described above, the insert rod 5 on another fixing rod 3 is inserted into the slot 4 fixed to the fixing rod 3 on the base plate 1, completing the positioning and fixing between the fixing rods 3, and ensuring that the connecting plates 7 on the fixing rods 3 are in an interlaced position. Then, a winnowing basket containing tea is placed between the two connecting plates 7. The device inserts the sidewalls of the winnowing basket into the arc-shaped grooves 9 on both sides. Under the action of the second spring 23, the circular wheel 18 on the inner sidewall of the arc-shaped groove 9 can be pressed tightly against the sidewall of the winnowing basket, thus completing the stable placement of the winnowing basket containing tea leaves. Through multi-layer distribution, convenient sun-drying processing of tea leaves can be achieved. When the device is connected to an external power source, the motor 19 is started by the external power source. The motor 19 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the circular wheel 18 on its sidewall to rotate. The circular wheel 18 drives the winnowing basket to move back and forth continuously. The vertical rod 12 continuously turns the tea leaves in the winnowing basket, resulting in a good sun-drying effect and avoiding damage to the tea leaves in later processing due to uneven sun-drying. The device has a good performance.
