Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea stir-frying device. Background Technology

[0002] "Firing" is one of the initial processing steps for green tea, yellow tea, black tea, oolong tea, pu-erh tea, and some red teas. Its main purpose is to destroy and deactivate the oxidase activity in fresh leaves through high temperatures, inhibit the enzymatic oxidation of tea polyphenols, evaporate some of the moisture from the fresh leaves, soften the tea leaves, making them easier to roll and shape, and at the same time, remove any grassy odor and promote the formation of a pleasant aroma.

[0003] Chinese Patent Publication No. CN103652010A discloses a tea-stirring device, which consists of a heating furnace, a wok, a stirrer, a rotating rod, a support, a shaft rotor, a thermal sensor, an engine, and a track. The wok is placed on the heating furnace, and the support is fixedly connected to the wok by welding. The rotating rod passes through the support and is rotatably connected to the support through the shaft rotor. The stirrer is set on the rotating rod, and the longitudinal direction of the stirrer is set at a 90-degree angle to the axial direction of the rotating rod. The stirrer is made of a biomimetic material based on the texture of human bones and skin. A thermal sensor is set at the tip of the stirrer. The rotating rod is connected to the engine through the track. The engine speed can be controlled according to the temperature inside the wok through the thermal sensor. The beneficial effects of this invention are: by monitoring the temperature inside the wok, the engine speed can be regulated, thereby improving the color, aroma, and taste of mechanically stir-fried tea, while also greatly reducing labor costs.

[0004] The aforementioned patent documents still have the following defects in practice:

[0005] The stir-frying handle is made of biomimetic material that mimics the texture of human bones and skin, and has heat sensors at the fingertips. The handle is fixed at a 90-degree angle to the axis of the rotating rod. After stir-frying, the tea leaves are dispersed in the pot and distributed on both sides of the handle. Some tea leaves may get stuck in the gaps of the handle, making it difficult to remove the tea leaves from the pot when discharging, resulting in uneven discharge. The presence of the handle also obstructs the operator's view, making it inconvenient for staff to remove the tea leaves. Utility Model Content

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figure 1 , Figure 2As shown, a tea-stirring device includes a base 1, a box 2 fixedly connected to the upper end of the base 1, double-layer supports 3 fixedly connected to the left and right sides of the upper end of the box 2, a hydraulic cylinder 6 fixedly connected to the middle of the upper end of the double-layer supports 3, a connecting rod 5 fixedly connected to the piston rod at the output end of the hydraulic cylinder 6, a transmission mechanism 2 8 fixedly connected to the rear of the lower end of the connecting rod 5, a stirring mechanism 9 fixedly connected to the lower part of the transmission mechanism 2 8, a supporting mechanism 10 rotatably connected to the upper rear end of the box 2, a transmission mechanism 1 4 fixedly connected to the front of the supporting mechanism 10, a gas stove 11 fixedly connected to the bottom wall of the box 2, and a drive mechanism 7 fixedly connected to the top of the lower layer of the double-layer supports 3.

[0029] The double-layer support 3 consists of an upper concave frame and a lower concave frame, with the upper concave frame installed on top of the lower concave frame;

[0030] The gas stove used in this case is a single-burner gas stove, which is a type of existing technology.

[0031] In this embodiment, the hydraulic cylinder 6 is first activated to lift the stir-frying mechanism 9 and the supporting mechanism 10. After manually starting the gas stove 11, the stir-frying mechanism 9 and the supporting mechanism 10 are lowered. After the supporting mechanism 10 is heated to the required temperature, the tea leaves are poured into the supporting mechanism 10. Then, the drive mechanism 7 is activated. The drive mechanism 7 rotates and drives the transmission mechanism 2 8 and the stir-frying mechanism 9 to rotate and stir-fry the tea leaves. After the stir-frying is completed, the drive mechanism 7 is turned off. At this time, the hydraulic cylinder 6 is activated. The hydraulic cylinder 6 rotates and drives the connecting rod 5, the transmission mechanism 1 4, the transmission mechanism 2 8 and the stir-frying mechanism 9 to move upward together, so that the stir-frying mechanism 9 is separated from the supporting mechanism 10. After the transmission mechanism 1 4 moves upward a certain distance, it begins to drive the supporting mechanism 10 to flip until the connecting rod 5 can no longer move upward.

[0032] After closing the hydraulic cylinder 6, the staff removes the tea leaves from inside the supporting mechanism 10. After removing the tea leaves, the staff starts the hydraulic cylinder 6, causing it to rotate in reverse. Then, the hydraulic cylinder 6 begins to drive the connecting rod 5, transmission mechanism 1 4, transmission mechanism 2 8, and stirring mechanism 9 to move downwards. After the transmission mechanism 1 4 moves downwards a certain distance, it drives the supporting mechanism 10 to rotate in reverse until it returns to its initial state. Then, the hydraulic cylinder 6 is closed.

[0033] In the above implementation process, in order to make the stirring mechanism 9 automatically rise so as to facilitate the discharge of the tea leaves after the stirring is completed, please refer to [reference needed]. Figure 4 The transmission mechanism 2 8 includes a shaft 1 81, the upper end of which extends through the lower row of concave frames to the upper part and is fixedly connected to the shaft of the pulley 2 74. A shaft 2 82 is slidably connected to the outer surface of the shaft 1 81. A rotating ring 83 is rotatably connected to the middle of the outer surface of the shaft 2 82. The shaft 2 82 has several block-shaped grooves 821 inside.

[0034] During implementation, shaft 82 is rotatably connected to rotating ring 83. Therefore, when shaft 81 drives shaft 82 to rotate, it will not drive rotating ring 83 to rotate. When connecting rod 5 drives rotating ring 83 to rise, rotating ring 83 will drive shaft 82 to rise. Since shaft 82 is slidably connected to the outer surface of shaft 81, when shaft 82 moves upward, it will not drive shaft 81 to move upward.

[0035] The inner annular array of shaft 2 82 has several block-shaped grooves 821, and the outer annular array of shaft 1 81 has several protrusions that match the block-shaped grooves 821.

[0036] During implementation, since the inner annular array of shaft 2 82 has several block-shaped grooves 821, and the outer surface of shaft 1 81 has several protrusions that are adapted to the block-shaped grooves 821, shaft 1 81 can drive shaft 2 82 to rotate, and shaft 2 82 can move up and down along the outer surface of shaft 1 81.

[0037] In order for the supporting mechanism 10 to rotate, see Figure 6 The supporting mechanism 10 includes a table 103, the rear end of which is rotatably connected to the upper rear end of the box 2, a wok 101 is fixedly connected to the inner cavity of the table 103, and a retaining ring 102 is fixedly connected to the upper part of the wok 101.

[0038] The front of the tabletop 103 rests on the front of the retaining ring 102, and the height of the front of the box 2 is lower than the height of the rear, so that the tabletop 103 remains stable in the initial state;

[0039] During implementation, when the transmission mechanism 4 moves upward, it will drive the wok 101, the retaining ring 102 and the table 103 to rotate together around the connection between the rear end of the table 103 and the upper rear end of the box 2, until the transmission mechanism 4 can no longer move upward.

[0040] The tea leaves are poured into the inner cavity of the wok 101 and stir-fried. During the stir-frying process, the baffle ring 102 extends the height of the wok 101 to prevent the tea leaves in the wok 101 from flying out of the wok 101 during the stir-frying.

[0041] Furthermore, in order to allow the stirring mechanism 9 to rise a certain distance before the supporting mechanism 10 flips over, see [reference needed]. Figure 5 The transmission mechanism 4 includes a connecting rod 41, the rear end of which is rotatably connected to the middle of the front end of the table 103. The front end of the connecting rod 41 is rotatably connected to a connecting rod 42, the upper end of which is rotatably connected to a connecting rod 43. The rear end of the connecting rod 43 is fixedly connected to the middle of the front end of the connecting rod 5. The rear end of the stop block 44 is fixedly connected to the middle of the front end of the retaining ring 102.

[0042] During implementation, the connecting rod 5 moves upward, causing the connecting rod 3 43 and the connecting rod 2 42 to move upward. The connecting rod 2 42 causes the connecting rod 1 41 to rotate around the front end of the table 103 until the connecting rod 1 41 is stopped by the stop block 44. As the connecting rod 5 continues to rise, the angle between the connecting rod 1 41 and the stop block 44 is fixed, while the angle between the connecting rod 1 41 and the connecting rod 2 42 continues to increase. Therefore, when the connecting rod 5 continues to rise, the connecting rod 1 41 and the stop block 44 begin to drive the table 103 to rotate around the rear end of the box 2 until the connecting rod 5 stops rising.

[0043] Example 2

[0044] To achieve the purpose of rotating the stirring mechanism 9 to stir-fry the tea leaves, please refer to... Figure 3 The drive mechanism 7 includes a first pulley 72, a transmission belt 73, and a second pulley 74. The first pulley 72 and the second pulley 74 are installed on the upper side of the top of the lower concave frame of the double-layer bracket 3. The transmission belt 73 is sleeved on the outer surface of the first pulley 72 and the second pulley 74. The lower end of the first pulley 72 is fixedly connected to a motor 71. The upper part of the motor 71 is fixedly connected to the lower side of the top of the lower concave frame of the double-layer bracket 3.

[0045] During implementation, motor 71 drives pulley 74 through pulley 72 and transmission belt 73. Pulley 74 drives transmission mechanism 8 to rotate. Transmission mechanism 8 drives frying mechanism 9 to start rotating and frying tea leaves.

[0046] For further details, please refer to [link / reference]. Figure 4 The stir-frying mechanism 9 includes a cross spatula 91, the upper center of the cross spatula 91 is fixedly connected to the lower end of the shaft 82, and several fixed rods 92 are fixedly connected to the upper end of the cross spatula 91.

[0047] During implementation, motor 71 drives pulley 72, transmission belt 73 and pulley 74 to rotate, shaft 82 drives cross spatula 91 to rotate, cross spatula 91 drives fixed rod 92 to rotate, stir-frying the tea leaves. The end of cross spatula 91 away from shaft 82 is raised, so that the bottom of cross spatula 91 is in contact with the upper surface of wok 101. When stir-frying the tea leaves, fixed rod 92 breaks up the clumps of tea leaves, so that the tea leaves are stir-fried more evenly.

[0048] Several heat dissipation slots are provided at both ends of the casing 2;

[0049] To prevent the gas stove 11 from continuously heating up and causing excessive gas pressure inside the housing 2, which could lead to an explosion, several heat dissipation slots are provided at both ends of the housing 2 to reduce gas pressure and maintain a certain temperature.

[0050] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic cylinder 6 and motor 71 used in this utility model are all conventional designs, and will not be described in detail here.

[0051] The working principle of this utility model is as follows: First, the hydraulic cylinder 6 is activated to lift the stirring mechanism 9 and the supporting mechanism 10. After manually starting the gas stove 11, the stirring mechanism 9 and the supporting mechanism 10 are lowered. After the wok 101 is heated to the required temperature, the tea leaves are poured into the inner cavity of the wok 101. Then, the motor 71 is started, which drives the shaft 81 and shaft 82 to rotate through the pulley 72, the transmission belt 73 and the pulley 74. The shaft 82 drives the cross spatula 91 and the fixed rod 92 to rotate and stir-fry the tea leaves. After the stir-frying is completed, the motor 71 is turned off. At this time, the hydraulic cylinder 6 is activated. The operation of the hydraulic cylinder 6 drives the connecting rod 5, the connecting rod 43, the connecting rod 42 and the rotating ring 83 upward. The moving and rotating ring 83 drives the shaft 82, the cross spatula 91 and the fixed rod 92 to move upward together, so that the cross spatula 91 separates from the inner cavity of the wok 101. At the same time, the connecting rod 42 moves upward, causing the connecting rod 41 to rotate around the front end of the table 103. When the connecting rod 5 rises to a certain distance, the connecting rod 41 is stopped by the stop block 44. At this time, the connecting rod 5 continues to rise, and the angle between the connecting rod 41 and the connecting rod 42 continues to increase. The connecting rod 41 and the stop block 44 simultaneously drive the wok 101, the retaining ring 102 and the table 103 to rotate around the rear end of the box 2 until the connecting rod 5 stops moving upward, the hydraulic cylinder 6 is closed, and then the staff takes out the tea leaves on the upper surface of the wok 101.

[0052] After the tea leaves are removed, the hydraulic cylinder 6 is started in reverse. The operation of the hydraulic cylinder 6 drives the connecting rod 5, connecting rod 3 43, connecting rod 2 42 and rotating ring 83 to move downward. The rotating ring 83 drives the shaft 2 82, the cross spatula 91 and the fixed rod 92 to move downward together. At the same time, the angle between connecting rod 2 42 and connecting rod 1 41 gradually decreases. Connecting rod 1 41 and stop block 44 simultaneously drive the wok 101, the retaining ring 102 and the table 103 to rotate around the rear end of the table 103 to the initial state. As the connecting rod 5 continues to move downward, it drives the connecting rod 1 41 to rotate around the rear end of the connecting rod 1 41 until the connecting rod 5 descends to the initial state, and then the hydraulic cylinder 6 is closed.
