Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea stem and leaf separation technology, specifically to tea stem and leaf separation equipment. Background Technology
[0002] Tea refers to the leaves and buds of the tea plant, which, after processing, can be made into a beverage. Tea contains many beneficial components, including catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all of which contribute to improved human health. During tea production, separation devices are used to sieve the tea leaves to remove stems and debris, thus selecting tea that meets quality requirements.
[0003] Chinese utility model patent application number CN202123327151.2 discloses a leaf stem separation device for tea processing. By setting a separation net cylinder, guide plate and auxiliary rod, it can not only separate and screen the tea stems in the tea leaves, but also effectively reduce the probability of tea damage.
[0004] While the aforementioned patent achieves the function of separating tea leaves and stems, it has the following drawbacks in use: The tea processing stem-seed separation equipment can only separate tea leaves and stems during sieving; it cannot separate tea fragments and powder mixed in with the stems. These fragments and powder can be recycled and reused; directly removing them along with the stems would be a waste of resources and inconvenient to use. Therefore, we propose a tea stem-leaf separation device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a tea stem and leaf separation device. This solves the problem that when tea processing tea stem and leaf separation devices screen tea leaves, they can only separate tea leaves and tea stems, but cannot separate tea leaves and powder mixed in with the tea stems. Tea leaves and powder can be recycled and reused, while directly removing them along with the tea stems would result in resource waste.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A tea stem and leaf separation device includes a base plate, a fixed frame fixedly connected to the top of the base plate, a connecting box fixedly connected to one side of the fixed frame, a sliding frame slidably connected to the inner wall of the connecting box, connecting rods symmetrically fixedly connected to one side of the sliding frame, a sieve plate fixedly connected to the end of the connecting rod away from the sliding frame, a collection frame slidably connected inside the fixed frame and below the sieve plate, a support plate fixedly connected to the top of the fixed frame, a rotating shaft rotatably connected inside the support plate, and a sieve cylinder fixedly connected to one end of the rotating shaft. In use, the sliding frame drives the sieve plate to reciprocate via the connecting rod, thereby separating tea leaves and powder mixed in with the tea stems through the sieve plate. The collection frame collects the separated tea leaves and powder. The rotating shaft drives the sieve cylinder to rotate, thereby separating the tea stems and leaves.
[0008] Preferably, a connecting frame is fixedly connected to one side of the support plate, and a motor is fixedly connected to the outside of the connecting frame. The output end of the motor is fixedly connected to the rotating shaft, and the rotating shaft is driven to rotate by the motor.
[0009] Preferably, a drive shaft is rotatably connected inside the connecting frame. The drive shaft is connected to the rotating shaft via a drive belt. Fixed rods are symmetrically fixed to the outside of the drive shaft. A rubber striking ball is fixedly connected to the end of the fixed rod away from the drive shaft. The rotating shaft drives the pulley on the outside of the drive shaft to rotate through the pulley on its outside and the drive belt, thereby driving the drive shaft to rotate. The drive shaft drives the rubber striking ball to rotate through the fixed rods, so that the rubber striking ball strikes the screen cylinder during the separation process, preventing the screen cylinder from becoming blocked.
[0010] Preferably, a connecting shaft is rotatably connected between the connecting box and the connecting frame. A second bevel gear is fixedly connected to one end of the connecting shaft, and a first bevel gear that cooperates with the second bevel gear is fixedly connected to the outer side of the rotating shaft. The rotating shaft drives the second bevel gear to rotate through the first bevel gear, thereby driving the connecting shaft to rotate.
[0011] Preferably, a connecting ring is fixedly connected to the end of the connecting shaft away from the second bevel gear, and a push rod is fixedly connected to the side of the connecting ring away from the connecting shaft. The sliding frame has a connecting groove inside that works with the push rod. The connecting shaft and the connecting ring drive the push rod to rotate, thereby working with the connecting groove. This allows the push rod to compress and drive the sliding frame to move back and forth during rotation.
[0012] Preferably, the outer side of the sieve cylinder is threaded with a sealing cap at equal intervals, which facilitates the addition and removal of tea leaves.
[0013] This utility model provides a tea stem and leaf separation device. Compared with the prior art, it has the following advantages:

[0022] 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.
[0023] Please see Figures 1 to 5 This utility model provides a technical solution:
[0024] The tea stem and leaf separation device includes a base plate 3, a fixed frame 1 fixedly connected to the top of the base plate 3, a connecting box 13 fixedly connected to one side of the fixed frame 1, a sliding frame 20 slidably connected to the inner wall of the connecting box 13, a connecting rod 21 symmetrically fixedly connected to one side of the sliding frame 20, a sieve plate 4 fixedly connected to the end of the connecting rod 21 away from the sliding frame 20, a collection frame 2 slidably connected inside the fixed frame 1 and below the sieve plate 4, a support plate 8 fixedly connected to the top of the fixed frame 1, a rotating shaft 11 rotatably connected inside the support plate 8, and a sieve cylinder 5 fixedly connected to one end of the rotating shaft 11. In use, the sliding frame 20 drives the sieve plate 4 to reciprocate through the connecting rod 21, thereby separating the tea leaves and powder mixed in with the tea stems through the sieve plate 4. The collection frame 2 can collect the separated tea leaves and powder. The rotating shaft 11 drives the sieve cylinder 5 to rotate, thereby separating the tea stems and leaves.
[0025] Furthermore, a connecting frame 9 is fixedly connected to one side of the support plate 8, and a motor 10 is fixedly connected to the outside of the connecting frame 9. The output end of the motor 10 is fixedly connected to the rotating shaft 11, and the rotating shaft 11 is driven to rotate by the motor 10.
[0026] Furthermore, a drive shaft 7 is rotatably connected inside the connecting frame 9. The drive shaft 7 is connected to the rotating shaft 11 via a drive belt 14. A fixing rod 6 is symmetrically fixed to the outside of the drive shaft 7. A rubber striking ball 19 is fixedly connected to the end of the fixing rod 6 away from the drive shaft 7. The rotating shaft 11 drives the pulley on the outside of the drive shaft 7 to rotate via its outer pulley and the drive belt 14, thereby driving the drive shaft 7 to rotate. The drive shaft 7 drives the rubber striking ball 19 to rotate via the fixing rod 6, so that the rubber striking ball 19 strikes the screen cylinder 5 during the separation process, preventing the screen cylinder 5 from becoming blocked.
[0027] Furthermore, a connecting shaft 12 is rotatably connected between the connecting box 13 and the connecting frame 9. A second bevel gear 18 is fixedly connected to one end of the connecting shaft 12. A first bevel gear 15 that works with the second bevel gear 18 is fixedly connected to the outer side of the rotating shaft 11. The rotating shaft 11 drives the second bevel gear 18 to rotate through the first bevel gear 15, which in turn drives the connecting shaft 12 to rotate.
[0028] Furthermore, a connecting ring 17 is fixedly connected to the end of the connecting shaft 12 away from the second bevel gear 18, and a push rod 16 is fixedly connected to the side of the connecting ring 17 away from the connecting shaft 12. The sliding frame 20 has a connecting groove 22 inside that works with the push rod 16. The connecting shaft 12 and the connecting ring 17 drive the push rod 16 to rotate, thereby working with the connecting groove 22. This allows the push rod 16 to squeeze and drive the sliding frame 20 to move back and forth during rotation.
[0029] Furthermore, the outer side of the sieve cylinder 5 is connected with a sealing cap by equidistant threads, which facilitates the addition and removal of tea leaves.
[0030] In use, unscrew the sealing cap on the outside of the sieve cylinder 5, add the tea leaves to be separated into the sieve cylinder 5, and start the motor 10. The motor 10 drives the sieve cylinder 5 to rotate via the rotating shaft 11, thereby separating the stems and leaves of the tea. The separated tea stems and tea fragments fall onto the sieve plate 4. At the same time, the rotating shaft 11 drives the pulley on the outside of the drive shaft 7 to rotate via its outer pulley and drive belt 14, which in turn drives the drive shaft 7 to rotate. The drive shaft 7 drives the rubber striking ball 19 to rotate via the fixed rod 6, thereby striking the sieve cylinder 5 during the separation process to prevent the sieve cylinder 5 from becoming blocked. During the rotation of the rotating shaft 11, the rotating shaft 11 drives the second bevel gear 18 to rotate through the first bevel gear 15. The second bevel gear 18 drives the push rod 16 to rotate through the connecting shaft 12 and the connecting ring 17, thereby cooperating with the connecting groove 22. This causes the push rod 16 to squeeze and drive the sliding frame 20 to move back and forth during the rotation. The sliding frame 20 drives the sieve plate 4 to move back and forth through the connecting rod 21, thereby separating the tea leaves and powder mixed in with the tea stems through the sieve plate 4. The collection frame 2 can be used to collect and process the separated tea leaves and powder, making the operation convenient.
