Description

Technical Field

[0001] This invention belongs to the field of tea processing withering technology, specifically a withering device for tea processing. Background Technology

[0002] Tea contains catechins, cholesterol, caffeine, inositol, folic acid, pantothenic acid, and other components that can improve human health and are loved by consumers. In the complex process of tea processing, tea withering is a crucial preliminary step. Its quality directly affects the aroma, taste, color, and feasibility of subsequent processing. Tea withering is an important step in tea making and the first step in tea processing. It refers to treating freshly picked tea leaves under appropriate conditions to gradually evaporate their moisture. After a series of chemical reactions, the enzyme activity of the tea leaves is inhibited, meeting the requirements for tea making.

[0003] During tea withering, the tea leaves need to be spread in a withering trough. In current technology, tea spreading is mainly done manually. Manual spreading can easily lead to uneven distribution of tea leaves, resulting in some areas where the tea leaves are too thick, hindering air circulation and causing slow moisture loss, while other areas where the tea leaves are too thin, causing rapid moisture loss. This affects the withering effect. Moreover, it is difficult to control the thickness of the tea leaves spread manually as needed. In addition, during the withering process, the tea leaves usually need to be turned over manually to speed up the withering process. However, manual turning is not only inefficient but also consumes a lot of manpower and time, thus causing inconvenience to the withering process.

[0004] Therefore, the present invention proposes a withering device for tea processing to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0041] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various modifications or alterations to the invention, and these equivalent forms also fall within the scope defined by this application.

[0042] like Figure 1-15 As shown, the withering device for tea processing according to the present invention includes a withering trough 1, a placement plate 2 fixedly connected inside the withering trough 1, and several evenly distributed through holes on the top surface of the placement plate 2. Hot air components are fixedly connected to both sides of the withering trough 1. The hot air components can blow hot air into the withering trough 1, thereby heating and withering the tea leaves on the placement plate 2, thus improving the withering efficiency of the tea leaves.

[0043] The withering trough 1 is provided with connecting blocks 3 on both the front and rear sides. Each connecting block 3 is connected to the withering trough 1 through a transmission assembly. An inverted U-shaped plate 4 is fixedly connected between the top surfaces of two connecting blocks 3. A horizontal plate 5 is provided inside the U-shaped plate 4. The horizontal plate 5 is connected to the U-shaped plate 4 through an adjustment assembly. Several evenly spaced turning plates 6 are fixedly connected to both sides of the bottom surface of the horizontal plate 5. The turning plates 6 on both sides of the horizontal plate 5 are arranged opposite to each other. Driven by the transmission assembly, the connecting blocks 3 can be moved. The movement of the connecting blocks 3 drives the movement of the U-shaped plate 4. The movement of the U-shaped plate 4 drives the movement of the turning plates 6. The movement of the turning plates 6 turns the tea leaves on the placement plate 2, saving the operator's physical labor, saving the turning time, and improving the turning efficiency.

[0044] The top surface of the U-shaped plate 4 is fixedly connected to the feeding box 7. A discharge port 8 is opened on one side of the feeding box 7. A baffle plate 9 is slidably connected inside the discharge port 8. A first adjusting screw 10 is rotatably connected to one side of the top surface of the feeding box 7. The bottom end of the first adjusting screw 10 is threadedly connected to the top surface of the baffle plate 9. A buffer plate 11 is provided inside the feeding box 7. The buffer plate 11 is inclined. One side of the buffer plate 11 is rotatably connected to the feeding box 7 via a first connecting shaft 47. One side of the bottom surface of the buffer plate 11 is fixedly connected to... Connect the first spring 12, the bottom end of the first spring 12 is fixedly connected to the feeding box 7; when it is necessary to spread the tea leaves evenly on the placement plate 2, pour the tea leaves into the feeding box 7, and then rotate the first adjusting screw 10. The rotation of the first adjusting screw 10 drives the baffle plate 9 to move upward, thereby exposing the discharge port 8, so that the tea leaves flow out from the discharge port 8 and fall onto the placement plate 2. At the same time, when the U-shaped plate 4 moves, it will drive the feeding box 7 to move, so that the tea leaves can be evenly spread on the placement plate 2.

[0045] The first motor 13 is fixedly connected to the front of the feeding box 7. One end of the shaft of the first motor 13 is fixedly connected to the horizontal shaft 14. The horizontal shaft 14 is rotatably connected to the feeding box 7. Several evenly distributed top rods 15 are fixedly connected to the outer periphery of the horizontal shaft 14. Each top rod 15 is fixedly connected to a rubber ball 16 at its free end. The rubber ball 16 slides and contacts the top surface of the buffer plate 11. When the tea leaves are laid out, the first motor 13 works, driving the horizontal shaft 14 to rotate. The rotation of the horizontal shaft 14 drives the top rods 15 and the rubber ball 16 to rotate. The rubber ball 16 intermittently contacts the buffer plate 11 and applies a downward pressure to the buffer plate 11. The first spring 12 is compressed and undergoes elastic deformation. With the cooperation of the rubber ball 16 and the first spring 12, the buffer plate 11 can swing up and down around the first connecting shaft 47, so that the tea leaves can fall smoothly from the discharge port 8, thus achieving the spreading of the tea leaves.

[0046] like Figures 1-4 As shown, the transmission assembly includes two fixed plates 17, both of which are fixedly connected to the withering groove 1. A second motor 18 is fixedly connected to one of the fixed plates 17. One end of the shaft of the second motor 18 is fixedly connected to a threaded rod 19. The threaded rod 19 is fixedly connected to the other fixed plate 17. Each threaded rod 19 passes through a corresponding connecting block 3 and is threadedly connected to the connecting block 3. A first limiting rod 20 is slidably connected to each connecting block 3. The first limiting rod 20 is located below the threaded rod 19, and both ends of the first limiting rod 20 are fixedly connected to the corresponding fixed plate 17.

[0047] Specifically, the second motor 18 operates, driving the threaded rod 19 to rotate. Under the limitation of the first limiting rod 20, the rotation of the threaded rod 19 can drive the connecting block 3 to move along the threaded rod 19. The movement of the connecting block 3 drives the U-shaped plate 4 to move. The first limiting rod 20 has a limiting effect on the connecting block 3, enabling the connecting block 3 to move stably along the threaded rod 19.

[0048] like Figure 1 , Figure 2 and Figure 5 As shown, the hot air assembly includes: a housing 21, which is fixedly connected to the withering trough 1; a blower fan 22 is fixedly connected inside the housing 21; an electric heating rod 37 is provided on one side of the blower fan 22 and is fixedly connected to the housing 21; air inlets 23 are opened on both sides of the withering trough 1 and are distributed front to back; an inspection port is opened on the housing 21 and a protective plate 24 is installed on each inspection port; a control box 25, an operation panel 26 and a control button 27 are fixedly connected to one of the housings 21.

[0049] Specifically, the heating rod 37 operates to generate heat, the fan 22 operates to generate airflow, and the heat is blown into the withering trough 1 through the air inlet 23, thereby withering the tea leaves on the placement plate 2; the control box 25 can control the electrical equipment in this invention, the operation panel 26 can operate and control the operation of this device, and the control button 27 can control the emergency stop of this device.

[0050] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the adjustment assembly includes: a second adjusting screw 28, which is rotatably connected to the U-shaped plate 4. The two ends of the second adjusting screw 28 have opposite threads. Both ends of the second adjusting screw 28 are threadedly connected to moving blocks 29. The bottom surface of each moving block 29 is hinged to two left and right distributed support rods 30. The bottom end of each support rod 30 is hinged to the top surface of the horizontal plate 5. Two left and right distributed second limiting rods 31 are fixedly connected to the U-shaped plate 4. The two second limiting rods 31 pass through the two moving blocks 29 and are slidably connected to the moving blocks 29.

[0051] Specifically, by rotating the second adjusting screw 28, under the limit of the second limiting rod 31, the two moving blocks 29 can move relative to each other (or in opposite directions) along the second adjusting screw 28. The movement of the moving blocks 29 drives the support rod 30 to move, the movement of the support rod 30 drives the horizontal plate 5 to move, and the movement of the horizontal plate 5 drives the flipping plate 6 to move, thereby adjusting the height of the flipping plate 6 to meet the flipping requirements of tea leaves of different thicknesses.

[0052] like Figure 1 , Figure 12 and Figure 13 As shown, the front and rear sides of the feeding box 7 are rotatably connected to the fixing rods 33 via the second connecting shafts 32. The two fixing rods 33 are fixedly connected to the guide plate 34 on one side. Two first magnets 35 are fixedly connected to the side of the guide plate 34 near the feeding box 7. Two second magnets 36 are fixedly connected to the upper side of the side of the feeding box 7. The first magnets 35 and the second magnets 36 can be attracted and connected.

[0053] Specifically, pulling the guide plate 34 outward causes the fixed rod 33 to rotate around the second connecting shaft 32, separating the first magnet 35 from the second magnet 36. This causes the guide plate 34 to tilt, catching the tea leaves falling from the outlet 8 and guiding them onto the placement plate 2, preventing the tea leaves from falling outside and avoiding waste. After the tea leaves are spread out, pulling the guide plate 34 upward causes the fixed rod 33 to rotate upward around the second connecting shaft 32, bringing the guide plate 34 into contact with the feeding box 7. This causes the first magnet 35 and the second magnet 36 to attract and connect, thus limiting the position of the guide plate 34 and ensuring its stability.

[0054] like Figure 2 , Figure 12 and Figure 13 As shown, a handle 38 is fixedly connected to the side of the guide plate 34 away from the material box 7.

[0055] Specifically, the handle 38 allows the operator to easily pull the guide plate 34, making it convenient for the operator to use.

[0056] like Figure 1 , Figure 12 and Figure 13 As shown, two reinforcing ribs 39 are fixedly connected to both sides of the bottom surface of the feeding box 7. Connecting rods 40 are fixedly connected to one side of the two reinforcing ribs 39 near the guide plate 34. An L-shaped support plate 41 is fixedly connected between the two connecting rods 40. The L-shaped support plate 41 can contact and cooperate with the guide plate 34.

[0057] Specifically, the reinforcing rib 39 provides support for the feeding box 7, making the connection between the feeding box 7 and the U-shaped plate 4 more stable and secure, thus ensuring the stability of the feeding box 7; with the cooperation of the connecting rod 40 and the L-shaped support plate 41, it can support the guide plate 34 in the downward state, ensuring the stability of the guide plate 34, thereby ensuring that the tea leaves can fall smoothly and stably onto the placement plate 2.

[0058] like Figure 9 , Figure 10 and Figure 11As shown, a placement groove 42 is opened on the other side of the buffer plate 11. A connecting plate 43 is slidably connected in the placement groove 42. The connecting plate 43 is connected to the placement groove 42 by a second spring 44. A baffle plate 45 is fixedly connected to the top surface of one side of the connecting plate 43. The baffle plate 45 is in contact with the buffer plate 11.

[0059] Specifically, under the elastic force of the second spring 44, one side of the connecting plate 43 can always slide in contact with the inner wall of the feeding box 7, thereby avoiding gaps between the buffer plate 11 and the feeding box 7 and preventing tea leaves from sliding to the bottom of the feeding box 7. With the cooperation of the baffle plate 45, the gap between the connecting plate 43 and the buffer plate 11 can be blocked, thereby again preventing tea leaves from falling to the bottom of the feeding box 7, ensuring that the tea leaves can fall completely from the buffer plate 11 onto the placing plate 2, and avoiding tea waste.

[0060] like Figure 1 , Figure 2 and Figure 4 As shown, universal wheels 46 are fixedly connected to the four corners of the bottom surface of the withering trough 1, and the universal wheels 46 have a braking function.

[0061] Specifically, the omnidirectional wheels 46 can move the device by rolling, which improves the flexibility of the device, makes it easier to move, and saves the operator's physical labor; the omnidirectional wheels 46 have a braking function, which can lock the omnidirectional wheels 46 in the use position and ensure the stability of the device.

[0062] The control box 25 of this solution includes a controller, which is one of an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It also includes a motherboard, memory modules, storage media, and a power supply, which is either AC power or a lithium battery. When a display screen is included, a graphics card is also provided. For the operating principle of the controller, please refer to "Automatic Control Principles," "Microcontroller Principles and Application Simulation Cases," and "Sensor Principles and Applications" published by Tsinghua University Press. Other books in this field can also be consulted. Other automation control and electrical components not mentioned are well-known to those skilled in the art and will not be elaborated upon here.

[0063] Working principle: First, the device is moved to the usage position by the rolling of the caster wheel 46, and then the caster wheel 46 is locked in the usage position by the braking function of the caster wheel 46.

[0064] Pour tea leaves into the feeding box 7, then rotate the first adjusting screw 10. The rotation of the first adjusting screw 10 causes the baffle plate 9 to move upward, thereby exposing the discharge port 8, which in turn causes the first motor 13 to work. The first motor 13 drives the horizontal shaft 14 to rotate, and the rotation of the horizontal shaft 14 drives the top rod 15 and the rubber ball 16 to rotate. The rubber ball 16 intermittently contacts the buffer plate 11 and applies a downward pressure to the buffer plate 11. The first spring 12 is compressed and produces elastic deformation. With the cooperation of the rubber ball 16 and the first spring 12, the buffer plate 11 can swing up and down around the first connecting shaft 47, so that the tea leaves can fall smoothly from the discharge port 8.

[0065] At the same time, the second motor 18 works, driving the threaded rod 19 to rotate. Under the limit of the first limit rod 20, the rotation of the threaded rod 19 can drive the connecting block 3 to move along the threaded rod 19. The movement of the connecting block 3 drives the U-shaped plate 4 to move. The movement of the U-shaped plate 4 drives the feeding box 7 to move. The movement of the feeding box 7 allows the tea leaves to be evenly spread on the placement plate 2, ensuring the uniformity of the tea leaf spreading, while reducing the physical labor of the operators and improving the efficiency of tea leaf spreading.

[0066] Then the heating rod 37 works to generate heat, and the fan 22 works to generate airflow, blowing the heat into the withering trough 1 through the air inlet 23, thereby withering the tea leaves on the placement plate 2. The two hot air components are set opposite to each other, so as to ensure that the hot air can evenly fill the withering trough 1 and ensure the uniformity of tea leaf withering.

[0067] When the tea leaves need to be turned over during the withering process, firstly, the second adjusting screw 28 is rotated. Under the limit of the second limiting rod 31, the two moving blocks 29 can move relative to each other (or in opposite directions) along the second adjusting screw 28. The movement of the moving blocks 29 drives the support rod 30 to move, the support rod 30 drives the horizontal plate 5 to move, and the horizontal plate 5 drives the turning plate 6 to move, thereby adjusting the height of the turning plate 6 to meet the turning requirements of tea leaves of different thicknesses. Then, the second motor 18 works, driving the threaded rod 19 to rotate. Under the limit of the first limiting rod 20, the rotation of the threaded rod 19 can drive the connecting block 3 to move along the threaded rod 19. The movement of the connecting block 3 drives the U-shaped plate 4 to move, and the movement of the U-shaped plate 4 drives the turning plate 6 to move, thereby turning the tea leaves over. Since the turning plate 6 is symmetrically distributed on both sides, the U-shaped plate 4 can continuously turn the tea leaves over during the forward and reverse rotation of the second motor 18, thus ensuring the turning effect.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
