Description

Technical Field

[0001] This utility model belongs to the field of tea processing technology, and in particular to a flat tea sorting device. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. From picking to finished tea, tea leaves require multiple processes, among which screening is a very important one. Traditional screening devices mostly use horizontal shaking to screen, but if flat tea leaves are inserted into the holes of the filter screen, it will not only easily damage the tea leaves, but also affect the normal screening process.

[0003] A search revealed a Chinese patent document (authorization announcement number CN221413896U) entitled "A Tea Sorting Device for Tea Processing," relating to the field of tea processing technology. The device includes a sorting body with a collection box slidably inserted inside, and a handle fixedly mounted on the collection box. A drying sieve plate is also located inside the sorting body. Furthermore, it includes a sieving component and a limiting component. The sieving component is rotatably inserted inside the sorting body and is used to sieve the tea leaves on the drying sieve plate. This invention has a reasonable structure. The harvested tea leaves are poured onto the drying sieve plate, and then a drive motor operates. The drive motor rotates the camshaft on the sieving component, allowing the drying sieve plate to vibrate against the camshaft due to spring force, ensuring even spreading of the tea leaves. The structure is simple and easy to operate. While this even spreading arrangement allows for good sieving, if flat tea leaves are inserted into the holes of the filter screen, it can easily damage the tea leaves and interfere with the sieving process. Utility Model Content

[0004] The purpose of this invention is to provide a flat tea leaf sorting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat tea leaf sorting device, comprising:

[0006] A screening bin with openings on both sides is used to screen flat tea leaves;

[0007] The receiving bucket, located on the outer periphery of the screening mesh bucket, is used to receive the tea leaves that have been screened out.

[0008] Two connecting ring plates are fixedly connected to the outer periphery of the screening screen barrel. The outer periphery of the connecting ring plates is rotatably connected to bearings. The fixed outer ring of the bearings is connected and fixed to the receiving barrel through multiple connecting rods.

[0009] One of the connecting ring plates has a fixed ring plate for blocking material fixedly connected to its side. A T-shaped connecting rod is fixedly connected to the inner wall of the fixed ring plate. A rotary motor that provides power to the connecting rod is installed on the vertical inner wall of the receiving hopper. Another connecting ring plate has a movable ring plate for blocking material abutting its side. Multiple transverse electric push rods are installed on the vertical inner wall of the receiving hopper away from the rotary motor. The moving parts of the transverse electric push rods are rotatably connected to the movable ring plate through auxiliary bearings.

[0010] As a preferred embodiment, the receiving hopper has an inclined rectangular channel on its vertical outer wall near the rotary motor, an inclined feeding frame is installed on the inner wall of the rectangular channel, and a movable frame corresponding to the position of the fixed ring plate is provided on the outer periphery of the feeding frame.

[0011] As a preferred embodiment, a material hopper is embedded in the top of the feeding frame, and multiple inclined electric actuators are installed on the outer periphery of the feeding frame. The moving parts of the inclined electric actuators are connected and fixed to the movable frame.

[0012] As a preferred embodiment, a viewing window is installed on the outer periphery of the receiving hopper.

[0013] As a preferred embodiment, the lower half of the receiving hopper is rotatably connected to a discharge plate, which is fixed to the receiving hopper by a latch.

[0014] As a preferred embodiment, a counterweight plate is provided below the receiving bucket, a lifting lug is fixedly connected to the bottom of the receiving bucket, a support plate is fixedly connected to the top of the counterweight plate, and the lifting lug is rotatably connected to the support plate through a rotating shaft.

[0015] As a preferred embodiment, two hydraulic rods are installed at the top of the counterweight plate, located on both sides of the support plate, and the moving parts of the hydraulic rods are connected to pulleys for abutting the receiving bucket.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] This flat tea leaf screening device uses a barrel-shaped screening mesh to screen flat tea leaves. A rotating motor drives a connecting rod to rotate, which in turn drives the screening mesh to rotate, achieving rotary filtration. Compared to flat filtration, even if flat tea leaves are inserted into the screening mesh, they will fall down when the device rotates to the top. Although they may still be inserted into the holes, they will not be continuously inserted and will not continuously affect the screening, thus ensuring the screening effect.

[0018] This flat tea leaf screening device uses two hydraulic rods that extend and retract in opposite directions to adjust the tilt angle of the receiving bucket, change the state of the flat tea leaves, improve the screening effect, and facilitate the unloading of tea leaves from the discharge plate. After the tea leaves are unloaded, the horizontal electric push rod is controlled to retract, releasing the movable ring plate from the screen bucket, allowing the flat tea leaves to be unloaded along the screen bucket and the receiving bucket.

[0019] When the flat tea leaves are to be fed, the tilting electric push rod is extended to allow the movable frame to penetrate into the circular channel of the fixed ring plate. The hopper can receive the falling flat tea leaves, which then move down along the feeding frame and the movable frame and finally fall into the screening bin. If the receiving bin is tilted at this time, the feeding efficiency and thoroughness can be improved.

[0020] This flat tea leaf screening device not only enables better screening but also assists in feeding and discharging the tea leaves. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can adopt existing methods such as bonding, welding, bolting, etc., depending on the actual needs.

However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0031] Please see Figures 1 to 3 As shown, a flat tea leaf sorting device, in this embodiment, includes:

[0032] The screening bin 1, which has openings on both sides, is used to screen flat tea leaves. The mesh size of the screening bin 1 is selected according to actual needs.

[0033] The receiving bucket 2 is located on the outer periphery of the screening bucket 1 and is used to receive the tea leaves that have been screened out.

[0034] Two connecting ring plates 3 are fixedly connected to the outer periphery of the screening screen barrel 1. The outer periphery of the connecting ring plate 3 is rotatably connected to the bearing 4. The fixed outer ring of the bearing 4 is connected and fixed to the receiving barrel 2 through multiple connecting rods 5.

[0035] One of the connecting ring plates 3 is fixedly connected to a fixed ring plate 6 for blocking material. A T-shaped connecting rod 7 is fixedly connected to the inner wall of the fixed ring plate 6. A rotary motor 8 that provides power to the connecting rod 7 is installed on the vertical inner wall of the receiving barrel 2. When the rotary motor 8 is turned on, the connecting rod 7 is driven to rotate, which indirectly drives the screening barrel 1 to rotate, realizing rotary filtration and screening. During this process, the opposite extension and retraction of the two hydraulic rods 19 are controlled back and forth to adjust the tilt angle of the receiving barrel 2, change the state of the flat tea leaves, and improve the screening effect.

[0036] Another connecting ring plate 3 has a side abutting a movable ring plate 9 for blocking material. Multiple horizontal electric push rods 10 are installed on the vertical inner wall of the receiving bucket 2 away from the rotating motor 8. The moving part of the horizontal electric push rod 10 is rotatably connected to the movable ring plate 9 through an auxiliary bearing. The tea residue is discharged from the channel at the discharge plate 15. After the tea residue is discharged, the horizontal electric push rod 10 is controlled to retract, releasing the movable ring plate 9 from the state of blocking the screening screen bucket 1, so that the flat tea leaves are discharged along the screening screen bucket 1 and the receiving bucket 2.

[0037] To meet the feeding requirements, the receiving hopper 2 has an inclined rectangular channel on its vertical outer wall near the rotary motor 8. An inclined feeding frame 11 is installed on the inner wall of the rectangular channel. A movable frame 12 corresponding to the position of the fixed ring plate 6 is set on the outer periphery of the feeding frame 11. A material gathering hopper 13 is embedded in the top of the feeding frame 11. Multiple inclined electric push rods 14 are installed on the outer periphery of the feeding frame 11. The moving part of the inclined electric push rod 14 is connected and fixed to the movable frame 12. When feeding is required, the inclined electric push rod 14 is controlled to extend, so that the movable frame 12 goes deep into the circular channel of the fixed ring plate 6. The material gathering hopper 13 can receive the falling flat tea leaves. The flat tea leaves move down along the feeding frame 11 and the movable frame 12 and finally fall into the screening screen hopper 1. After feeding is completed, the inclined electric push rod 14 is controlled to reset.

[0038] The outer periphery of the receiving hopper 2 is equipped with a viewing window, and multiple vibrators can also be installed at the bottom of the receiving hopper 2 to improve the thoroughness of material discharge.

[0039] The lower half of the receiving bucket 2 is rotatably connected to the side of the receiving bucket 2. The unloading plate 15 is connected and fixed to the receiving bucket 2 by a lock. A counterweight plate 16 is provided at the bottom of the receiving bucket 2. A lifting lug 17 is fixedly connected to the bottom of the receiving bucket 2. A support plate 18 is fixedly connected to the top of the counterweight plate 16. The lifting lug 17 is rotatably connected to the support plate 18 by a rotating shaft. Two hydraulic rods 19 are installed at the top of the counterweight plate 16, which are located on both sides of the support plate 18. The moving part of the hydraulic rod 19 is connected to a pulley 20 for abutting the receiving bucket 2.

[0040] The rotary motor 8, the transverse electric actuator 10, the tilting electric actuator 14, and the hydraulic rod 19 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0041] Working principle

[0042] When the flat tea leaf screening device needs to be fed, the inclined electric push rod 14 is extended, so that the movable frame 12 is inserted into the circular channel of the fixed ring plate 6. The hopper 13 can receive the falling flat tea leaves. The flat tea leaves move down along the feeding frame 11 and the movable frame 12 and finally fall into the screening barrel 1. After feeding is completed, the inclined electric push rod 14 is reset, the rotary motor 8 is turned on, and the connecting rod 7 is rotated, which indirectly drives the screening barrel 1 to rotate, realizing rotary filtration and screening. During this process, the opposite extension and retraction of the two hydraulic rods 19 are controlled back and forth to adjust the tilt angle of the receiving barrel 2, change the state of the flat tea leaves, improve the screening effect, and facilitate the unloading of tea residue from the channel at the unloading plate 15. After the tea residue is unloaded, the horizontal electric push rod 10 is retracted to release the state of the movable ring plate 9 blocking the screening barrel 1, so that the flat tea leaves are unloaded along the screening barrel 1 and the receiving barrel 2.
