Description

Technical Field

[0001] The invention relates to the field of tea production and processing, in particular to an integrated tea leaf shaking and airing machine. Background Art

[0002] The so-called "overturned rivers and seas produce oolong tea" refers to the process of shaking tea leaves, which is an important step in making oolong tea. Shaking tea leaves means putting many tea leaves together and shaking them continuously to make them collide with each other, slightly damaging the leaf edge cells of the green leaves and causing local oxidation, which provides the basis for forming the appearance characteristics of "green leaves with red edges", promotes and intensifies the production of various reactions of tea substances and the formation of quality, coordinates the tea quality, and reduces green smell. Shaking tea leaves plays a role in moving water, dissipating heat, and promoting quality formation.

[0003] Tea leaves are generally shaken four times: The first time, the shaking time should be short and gentle, in order to preserve the green and water, ensure that the fresh leaves remain active and breathe normally, so as to achieve the purpose of "water loss". The second time, the shaking time can be slightly longer, at this time, observe the color and smell the fragrance. The third and fourth times, the shaking should be heavier, so that the green smell in the fresh leaves can be dispersed, and the formation of aromatic substances in the fresh leaves can be better enhanced. Each time, the green smell should be light, the leaves should be light yellow in the green, and the edges of the leaves should have red edges. The time interval between each shaking is: stop shaking until the green smell disappears and the leaves on the surface become wilt and soft, then shake it in time to "live" to prevent the leaves from "dying green" due to excessive water loss. It is related to the temperature and humidity in the room, and needs to be observed carefully.

[0004] Therefore, at present, high-quality tea withering still adopts manual withering. Workers judge the withering time according to experience. However, pure manual withering consumes a great deal of physical strength of tea-making masters. Moreover, with a large number of withering times, the number of baskets that a master can be responsible for is limited, resulting in low tea production efficiency. To save the physical strength of masters and improve production efficiency, in the prior art, there is an artificial auxiliary device exemplified by the patent application number: 200710009912.5, and the patent name: A water sieve withering machine. Placing the basket containing tea on this device can replace manual withering. Due to the structural characteristics of the device itself, the tea after withering will gather in the middle of the basket, and the basket is always in an inclined state. After withering, it is necessary to manually adjust the angle of the basket and spread the tea around the middle position of the basket. Although it solves the problem of physical strength consumption in withering to a certain extent, there are still many inconveniences, and the actual production efficiency has not been significantly improved. The prior art also provides a device with the patent application number: 201410432697.X, and the patent name: A tea withering machine. This device is a drum-type withering machine, which realizes withering by placing a large amount of tea in the roller and can wither a large amount of tea in sequence. However, when withering tea, it is necessary to adjust in time according to the situation of the tea, and it takes a period of time for the tea to stop withering after each withering. In this device, it is not convenient to observe the withering condition of the tea, and it is also inconvenient to disperse and air-dry the tea during the stop-withering link. Therefore, it is not suitable for high-quality tea.

[0005] Therefore, in order to ensure the withering effect and quality while greatly improving production efficiency and reducing the labor intensity of workers, there is an urgent need for a new device to improve the deficiencies existing in the original device at present. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an integrated tea withering and air-drying machine, which effectively solves the problems raised in the background art.

[0007] The technical solution for solving the problem includes a vertical circular tube, in which a smooth rod is slidably installed coaxially. At the upper end of the circular tube, an electric cylinder is fixed to drive the smooth rod to move up and down. Along the length direction of the circular tube, multiple groups of withering units are evenly distributed at intervals. Each group of withering units includes a horizontal support rod fixed on the smooth rod. Below the free end of the support rod, a horizontal telescopic rod is rotatably installed. Multiple telescopic rods can be driven to rotate synchronously. Each group of withering units also includes an L-shaped rod placed below the support rod and fixed on the circular tube. The upper end of the L-shaped rod is coaxial with the rotation center of the telescopic rod. Above the L-shaped rod, a disc-shaped groove is provided. The center position of the lower end face of the disc-shaped groove is connected to the upper end of the L-shaped rod through a spherical hinge. An annular groove is provided on the outer circular surface of the disc-shaped groove. A spherical slider is provided in the annular groove. The free end of the telescopic rod is connected to the spherical slider through an L-shaped connecting rod. Below the telescopic rod, an arc-shaped baffle is fixed. The lower end of the arc-shaped baffle gradually increases from the inside to the outside of the rotation center of the telescopic rod.

[0008] Preferably, a base is provided below the circular tube, and the circular tube is fixed on the base.

[0009] Preferably, the support rod penetrates and is fixed on the smooth rod. The lengths of the telescopic rods extending out of the smooth rod are different. Below the longer end of the support rod extending out of the smooth rod, a first pulley is rotatably installed. The telescopic rod is fixed on the first pulley. The axis of rotation of the telescopic rod is the axis of the first pulley. Below the shorter end of the support rod extending out of the smooth rod, an internal gear ring is rotatably installed. Below the internal gear ring, a second pulley is fixed. A belt is connected between the first pulley and the second pulley. The diameter of the second pulley is larger than that of the first pulley. The circular tube is placed inside the belt. A gear shaft driven by a motor is provided on the outer side of the circular tube. Multiple second pulleys and the internal gear rings are sleeved on the gear shaft. The second pulley does not contact the gear shaft, and the internal gear ring meshes with the gear shaft for transmission.

[0010] Preferably, through grooves for the support rod to penetrate and slide are provided on both sides of the circular tube.

[0011] Preferably, a spring for assisting the telescopic rod to retract and reset is sleeved on the telescopic rod.

[0012] Preferably, a ball head is fixed at the center position of the lower end of the disc-shaped groove through a support block. A ball head hinge seat is fixed at the upper end of the L-shaped rod. The ball head and the hinge seat can only allow the disc-shaped groove to swing up and down, and cannot realize the rotation of the disc-shaped groove.

[0013] Preferably, the arc-shaped baffle is a comb-shaped plate.

[0014] The device realizes the up and down movement of the support rod through the telescopic movement of the electric cylinder to change the position of the force swing of the disc groove. When the disc groove is under force at the highest position and the lowest position, the disc groove is in an inclined state in essence. However, when the disc groove is under force at the highest position, the arc-shaped baffle does not contact. The rapid rotation of the motor causes the disc groove to swing circumferentially around the ball hinge position to realize the shaking of the tea leaves, and makes the tea leaves pile up in the middle. When the disc groove is under force at the lowest position and the disc groove is driven to swing around the ball hinge position, the arc-shaped baffle contacts. At this time, the rotation speed of the motor is relatively low, so that the piled-up tea leaves are evenly dispersed into the bamboo basket under the action of the arc-shaped baffle, which is convenient for the withering of the tea leaves. The whole process can realize semi-automatization, and with the addition of the experience of workers, it can effectively improve the production efficiency of the tea leaves and ensure the quality of the tea leaves.

[0019] The following further describes in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0020] As Figures 1 to 4 can be seen, the present invention includes a vertical circular tube 1. A polished rod 2 is coaxially and slidably installed in the circular tube 1. An electric cylinder 3 capable of driving the polished rod 2 to move up and down is fixed at the upper end of the circular tube 1. Along the length direction of the circular tube 1, multiple groups of tea leaf shaking units are evenly distributed at intervals. Each group of tea leaf shaking units includes a horizontal support rod 4 fixed on the polished rod 2. Below the free end of the support rod 4, a horizontal telescopic rod 5 is rotatably installed. Multiple telescopic rods 5 can be synchronously driven to rotate. Each group of tea leaf shaking units further includes an L-shaped rod 6 placed below the support rod 4 and fixed on the circular tube 1. The upper end of the L-shaped rod 6 is coaxial with the rotation center of the telescopic rod 5. Above the L-shaped rod 6, there is a disc groove 7. The center position of the lower end surface of the disc groove 7 is connected to the upper end of the L-shaped rod 6 through a ball hinge. An annular groove 8 is provided on the outer circular surface of the disc groove 7. A spherical slider 9 is provided in the annular groove 8. The free end of the telescopic rod 5 is connected to the spherical slider 9 through an L-shaped connecting rod 10. Below the telescopic rod 5, an arc-shaped baffle 11 is fixed. The lower end of the arc-shaped baffle 11 gradually increases from the inside to the outside of the rotation center of the telescopic rod 5.

[0021] In order to facilitate the installation and fixation of the device, a base 12 is provided below the circular tube 1, and the circular tube 1 is fixed on the base 12.

[0022] In order to achieve the synchronous drive of multiple telescopic rods 5, the support rod 4 penetrates and is fixed on the optical rod 2. The lengths of the telescopic rods 5 extending out of the optical rod 2 are different. A first belt pulley 13 is rotatably installed below the longer end of the support rod 4 extending out of the optical rod 2. The telescopic rod 5 is fixed on the first belt pulley 13. The rotation center axis of the telescopic rod 5 is the axis of the first belt pulley 13. A ring gear 14 is rotatably installed at the shorter end of the support rod 4 extending out of the optical rod 2. A second belt pulley 15 is fixed below the ring gear 14. The first belt pulley 13 and the second belt pulley 15 are connected by a belt. The diameter of the second belt pulley 15 is larger than that of the first belt pulley 13. The circular tube 1 is placed inside the belt. A gear shaft 16 driven by a motor is provided on the outer side of the circular tube 1. Multiple second belt pulleys 15 and the ring gear 14 are sleeved on the gear shaft 16. The second belt pulley 15 does not contact the gear shaft 16. The ring gear 14 meshes with the gear shaft 16 for transmission.

[0023] In order to facilitate the passing of the support rod 4, through grooves 17 for the support rod 4 to pass through and slide are provided on both sides of the circular tube 1.

[0024] In order to achieve the auxiliary reset of the telescopic rod 5, a spring 18 that can assist it to retract and reset is sleeved on the telescopic rod 5.

[0025] In order to achieve the ball hinge between the disc-shaped groove 7 and the L-shaped rod 6, a ball head is fixed at the center position of the lower end of the disc-shaped groove 7 through a support block. A ball head hinge seat is fixed at the upper end of the L-shaped rod 6. The ball head and the hinge seat can only satisfy the up and down swing of the disc-shaped groove 7 and cannot achieve the rotation of the disc-shaped groove.

[0026] In order to achieve a better combing and guiding effect of the arc-shaped baffle, the arc-shaped baffle 11 is a comb-shaped plate.

[0027] The specific working process of the present invention: When the device is in use, the electric cylinder 3 is used to control the optical rod 2 to rise. The rising of the optical rod 2 causes the optical rod 2 to drive multiple support rods 4 to rise. During this process, the first belt pulley 13, the second belt pulley 15, the ring gear 14, and the telescopic rod 5 all move upward synchronously, but the L-shaped rod 6 does not move. Therefore, when the electric cylinder 3 moves upward, the disc-shaped groove 7 will be inclined and the spherical slider 9 will be at the highest position of the annular groove 8 in the inclined disc-shaped groove 7. At this time, the motor is rotated to make the free end of the telescopic rod 5 face the direction of the circular tube 1. At this time, the device is in a Figure 1The state shown is such that a bamboo basket filled with tea leaves can be placed in the notch of the disc-shaped groove 7. The depth and size of the notch of the disc-shaped groove 7 exactly match the bamboo basket installed thereon, and the bamboo basket will not fall out of the notch of the disc-shaped groove 7 during shaking. After installation, the motor can be started to make the motor rotate. The motor here can drive forward and reverse rotation, and the rotation speed of the motor can be adjusted. The rotation of the motor causes the connecting rod 10 on the telescopic rod 5 to be the driving force, and the connecting rod 10 rotates around the disc-shaped groove 7, making the trajectory of the spherical slider 9 driven by the connecting rod 10 the highest position of the inclined disc-shaped groove 7. When the connecting rod 10 rotates and the highest position of the disc-shaped groove 7 rotates accordingly, the withering of the tea leaves is realized. During this withering process, the tea leaves will gather towards the middle of the bamboo basket and finally form a bulge in the middle of the bamboo basket. During this process, due to the shape of the arc-shaped baffle 11 being similar to a right triangle and the relatively large gap between the telescopic rod 5 and the disc-shaped groove 7, the arc-shaped baffle 11 never contacts the tea leaves during the process of the telescopic rod 5 rotating to drive the disc-shaped groove 7 to shake and sieve.

[0028] The master can control the withering time according to different withering sequences, so as to control the withering effect. When the withering is completed, the electric cylinder 3 is controlled to extend, causing the polished rod 2 to move downward. During this process, the spherical slider 9 driven by the telescopic rod 5 and the connecting rod 10 moves downward. During this process, the disc-shaped groove 7 gradually changes from an inclined state to a horizontal state and then to an inclined state. At this time, the spherical slider 9 is placed at the lowest point of the inclined annular groove 8. As shown in the attached Figure 2 figure. In this state, the spherical slider 9 has reached the driving point, but the position of this driving point is the lowest end position of the inclined disc-shaped groove 7. At this time, due to the shape of the arc-shaped baffle 11 being similar to a right triangle, the lower end of the arc-shaped baffle 11 is parallel to the upper end surface of the disc-shaped groove 7. The comb teeth near the middle position of the arc-shaped baffle 11 are inserted into the tea leaves bulging in the middle of the bamboo basket, and under the drive of the motor, the tea leaves contact the comb teeth and are gradually dispersed evenly in the bamboo basket under the action of the comb teeth. During this process, the rotation speed of the motor should be slow, and the rotation direction of the motor should adapt to the arc direction of the arc-shaped baffle 11. After the tea leaves are processed, the motor is turned off to make the tea leaves stop withering. According to the master's experience, controlling the opening and closing of the motor can realize withering again until the tea leaves are completely withered, and then the withered tea leaves can be directly air-dried on this device.

[0029] The advantages of this device compared with traditional equipment are as follows:

[0030] 1. This device holds the bamboo baskets through multiple evenly spaced disk-shaped grooves 7 arranged vertically. With the drive of a single motor, synchronous withering operations can be achieved for multiple groups of bamboo baskets up and down. The reason for this operation is that the quality of the tea leaves in the same batch is quite similar. Therefore, based on the state of the tea in one bamboo basket, the state of the tea in multiple bamboo baskets can be analogized synchronously. Achieving withering for the tea in multiple bamboo baskets at one time can effectively improve efficiency. At the same time, mechanical automation for withering can greatly reduce the labor intensity of workers. During this process, workers only need to control the motor based on experience.

[0031] 2. The telescopic movement of the electric cylinder 3 is used to move the support rod 4 up and down, changing the position where the disk-shaped groove 7 sways under force. When the disk-shaped groove 7 is at the highest position and the lowest position under force, the disk-shaped groove 7 is essentially in an inclined state. However, when the disk-shaped groove 7 is at the highest position under force, the arc-shaped baffle 11 does not contact. The rapid rotation of the motor causes the disk-shaped groove 7 to swing circularly around the ball hinge position to achieve withering, and makes the tea leaves pile up in the middle. After the disk-shaped groove 7 is at the lowest position under force and is driven to swing around the ball hinge position, the arc-shaped baffle 11 contacts. At this time, the rotation speed of the motor is relatively low, so that the piled-up tea leaves can be evenly dispersed into the bamboo basket under the action of the arc-shaped baffle 11, facilitating the static withering of the tea leaves. The whole process can achieve semi-automation. With the addition of workers' experience, it can effectively improve the production efficiency of tea leaves and ensure the quality of tea leaves.

[0032] 3. This device has a delicate structure and is easy for workers to operate. The whole process only requires workers to control the rotation of the motor and the telescopic movement of the electric cylinder 3. The production cost of this device is low, which is convenient for large-scale production, procurement, and use. Using this device can also reduce the operation space in the workshop, saving labor costs and space costs.
