Description

Technical Field

[0001] This utility model relates to the technical field of tea sorting equipment, and in particular to a tea blowing sorting and conveying line with a slide rail docking structure. Background Technology

[0002] Tea, as an agricultural product with high quality requirements, often needs to be sorted according to physical parameters such as shape, weight, density, and windward area during its processing to improve the accuracy of subsequent packaging, sales, and quality grading. Among these methods, the blower sorting method has become a commonly used method in current tea grading due to its advantages such as non-contact, non-damaging, and highly adaptable processing.

[0003] The tea leaf sorting and conveying line is an automated device that integrates air sorting, material receiving, and synchronous conveying into a single system. Its core principle is to generate a stable airflow through a blower system, causing tea leaves with different physical properties to follow different flight paths in the air and fall into their respective sorting and receiving areas. From there, the conveying structure transports them to the corresponding collection ports, thus achieving integrated, highly efficient, and continuous graded conveying.

[0004] However, existing tea leaf sorting and conveying equipment still has some technical problems. For example, the airflow zones between layers in the multi-layer sorting structure are uneven, with many dead zones, resulting in unstable sorting effects; the conveying paths after material is received at each layer are chaotic, often leading to tea mixing and overlapping conveying trajectories; the conveying modules are generally fixed structures, which are not conducive to cleaning, disassembly, maintenance, or structural expansion, resulting in insufficient equipment versatility and flexibility; material blockage is prone to occur in the unloading stage, causing airflow obstruction or disordered sorting rhythm, affecting the overall stability of the machine. Therefore, there is an urgent need for a compact, functionally coordinated, detachable and expandable, and high-precision blower sorting and conveying line to improve the intelligence and standardization of tea processing. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a tea blowing sorting and conveying line with a sliding rail docking structure to solve the problems of low sorting accuracy, low utilization rate of the wind zone, and easy confusion of the conveying path in the existing tea blowing sorting and conveying equipment.

[0006] To achieve the above objectives, this utility model provides a tea leaf air-blowing sorting and conveying line with a slide rail docking structure, including a shell, sorting components, feeding components, and conveying components;

[0007] The sorting component is located inside the outer casing and is used to sieve and separate the tea leaves according to their size and weight, and then process them into separate zones.

[0008] The feeding component, located above the outer shell, is used to feed tea leaves at a directional position. It works in conjunction with the sorting component to achieve uniform sorting of tea leaves.

[0009] A conveying assembly, located inside the housing and on one side, is used to directionally separate and convey the sorted tea leaves to their respective locations.

[0010] Preferably, the sorting assembly includes a blower body, which is fixedly installed on one side of the housing. An air guide is fixedly installed on one side of the blower body, and one side of the air guide is connected to the interior of the housing. A first pulley is rotatably installed on one side of the blower body. Multiple conveyor belts are rotatably installed inside the housing. The distance between the conveyor belts and the air guide is gradually increasing. That is, the starting point of the uppermost conveyor belt is farthest from the air guide, the starting point of the middle conveyor belt is less than the starting point of the uppermost conveyor belt, and the starting point of the lowermost conveyor belt is the smallest.

[0011] Preferably, the feeding assembly includes a feeding hopper, which is fixedly installed on one side of the housing. The feeding hopper is located directly above the feed inlet of the housing. A third pulley is rotatably installed on one side of the feeding hopper. The third pulley is connected to the first pulley via a belt. A spring is fixedly installed on one side of the third pulley, and an impact hammer is fixedly installed on the other end of the spring. The length of the spring is greater than the distance between the third pulley and the feeding hopper.

[0012] Preferably, the conveying assembly includes multiple slide rail bodies, which are inserted into the lower part of the housing. The number and position of the slide rail bodies correspond to the number of conveyor belts. A slot is provided on one side of each slide rail body, and a plug is fixedly installed on the other side of each slide rail body. The plug and the slot cooperate with each other.

[0013] Preferably, a ventilation plate is fixedly installed on one side of the slide rail body, and the ventilation plate is a plate-shaped part with a grid.

[0014] Preferably, the conveyor belt is sleeved on two rotating rollers, which are rotatably mounted to the inner wall of the outer casing. A second pulley is fixedly mounted on the rotating roller near the blower body. The second pulley is located on the outer side of the outer casing. The second pulley is connected to the first pulley by a belt, and every two second pulleys are also connected by a belt for transmission.

[0015] Preferably, the slot is a T-shaped slot and the plug is a T-shaped block, and the two are plugged into each other and used together.

[0016] Preferably, an electric motor is fixedly installed on one side of the blower body, the drive shaft of the electric motor is fixedly connected to the fan blades inside the blower body, and a baffle is fixedly installed inside the outer casing at a position directly below the material discharge of the hopper.

[0017] The beneficial effects of this utility model are:

[0018] 1. This tea sorting and conveying line with a sliding rail docking structure utilizes a blower to generate a stable airflow. Multiple conveyor belts with progressively closer starting points to the air inlets create a sorting zone, allowing tea leaves with different physical properties to fall onto conveyor belts at different heights according to the airflow path. This achieves layered sorting, where light, flaky tea leaves are blown further and heavier tea stems fall shorter, significantly improving the fineness and accuracy of the screening. Simultaneously, the guiding structure of the air inlets and ventilation plates optimizes the airflow direction and pressure differential distribution, reducing dead zones and turbulent areas, and increasing the effective sorting area.

[0019] 2. This tea leaf sorting and conveying line with a sliding rail docking structure uses a third pulley linked to a spring and an impact hammer to construct a simple and efficient automatic feeding vibration mechanism. It can generate periodic slight impacts in accordance with the rhythm of the main drive, preventing tea leaves from getting stuck due to static electricity, moisture, or structural bridging. This achieves a continuous, intermittent, and uniform feeding method. In conjunction with the working rhythm of the air field, it effectively ensures the stability of the air pressure in the air screen zones, improves the overall sorting efficiency and consistency, and reduces the frequency of manual intervention.

[0020] 3. This tea sorting and conveying line with a sliding rail docking structure employs a T-shaped slot and 16-block modular connection structure between the sliding rail body and the outer casing. This ensures that each sorting conveyor belt is docked with its corresponding conveying channel, guaranteeing a clear, non-intersecting, and non-mixed path for the tea from sorting to conveying. This structure not only features self-guiding, self-limiting, and anti-misinstallation functions, but also supports quick disassembly and replacement of the sliding rail body. Users can expand and adjust the conveying direction and length of the sliding rails as needed, greatly improving the adaptability and maintainability of the equipment. Attached Figure Description

[0032] like Figures 1 to 6 As shown, a tea leaf sorting and conveying line with a sliding rail docking structure includes a housing 1, a sorting component, a feeding component, and a conveying component.

[0033] Furthermore, such as Figures 1 to 3As shown, the sorting component, located inside the outer casing 1, is used to sieve and separate tea leaves according to size and weight, and process them into different zones. It includes a blower body 3, which is fixedly installed on one side of the outer casing 1. An air guide 10 is fixedly installed on one side of the blower body 3, and one side of the air guide 10 is connected to the interior of the outer casing 1. A first pulley 4 is rotatably installed on one side of the blower body 3. Multiple conveyor belts 8 are sequentially mounted inside the outer casing 1, with the distance between the conveyor belts 8 and the air guide 10 gradually increasing. Specifically, the starting point of the topmost conveyor belt 8 is furthest from the air guide 10, the middle conveyor belts 8 are less distant from the air guide 10 than the topmost conveyor belt 8, and the bottommost conveyor belt 8 is furthest from the air guide 10. The distance between the air vents 10 and the outer casing 1 is minimized. A ventilation plate 7 is fixedly installed on one side of the slide rail body 11. The ventilation plate 7 is a plate-shaped part with a grid. The conveyor belt 8 is sleeved on two rotating rollers. The rotating rollers are rotatably installed on the inner wall of the outer casing 1. A second pulley 5 is fixedly installed on the rotating roller near the blower body 3. The second pulley 5 is located on the outside of the outer casing 1. The second pulley 5 is connected to the first pulley 4 by a belt. Each pair of second pulleys 5 is also connected by a belt for transmission. A motor 12 is fixedly installed on one side of the blower body 3. The drive shaft of the motor 12 is fixedly connected to the fan blades inside the blower body 3. A baffle 9 is fixedly installed inside the outer casing 1 at the position directly below the material discharge of the hopper 2. Multiple conveyor belts 8 are arranged sequentially inside the outer casing. Its starting point gradually approaches the air guide 10, allowing tea leaves to fall onto conveyor belts 8 at different heights according to their different characteristics such as weight and area under the action of wind. Multi-stage screening is more refined, the sorting efficiency is high, dead zones of wind are reduced, and the utilization rate is improved. The blower body 3 is equipped with a first pulley 4 on one side, which drives multiple second pulleys 5 through a belt, so that multiple conveyor belts 8 can be linked in a unified manner with strong synchronization. This avoids material accumulation or jamming caused by misalignment of conveyor belts 8. The structure is compact, and the transmission system is uniformly arranged on one side for centralized maintenance. The sorting belt speed can be adjusted by changing the belt or pulley ratio to adapt to different tea leaves. The blower body 3 is directly driven by an electric motor 12, and the transmission shaft is fixedly connected to the internal fan blades to form a high-efficiency blowing force field, which can form with the conveyor belts 8 at different starting points below. The well-designed air-screening partition, with baffle 9 positioned directly below the feed hopper 2, helps control the tea leaves' drop position, preventing disordered drop that could affect the air-sorting effect and avoiding direct drop into the bottom layer. This ensures tea leaves enter the air-screening partition sequentially from the top, reducing sorting errors. The ventilation plate 7, designed in a mesh pattern, effectively guides airflow in conjunction with the blower, while also facilitating dust removal. The multi-stage conveying, adjustable airflow, and sliding rail combination structure allow the equipment to adapt to various sizes, densities, and shapes of tea raw materials, including loose leaves, fragments, powder, and tea stems. The sliding rail body 11 is located on one side of the housing 1, enabling sliding docking of equipment modules for quick installation / disassembly and subsequent expansion of the conveying length or sorting function units. During operation, the tea raw materials enter the equipment through the feed hopper 2.The tea leaves fall above the sorting area, guided by baffle 9 during the dropping process to prevent direct penetration to the bottom layer, ensuring step-by-step sorting from top to bottom. Motor 12 starts, driving the fan blades inside blower body 3 to rotate at high speed, generating a stable airflow. This airflow is guided into the outer casing through air vent 10, forming a wind force action surface at a certain angle in the sorting area. The airflow blows from one side to multiple conveyor belts 8 (divided into upper, middle, and lower layers according to height), classifying the tea leaves according to their physical characteristics (weight, shape, and windward area). Lighter, flaky tea leaves are easily blown further by the wind and fall onto the uppermost conveyor belt 8, while medium-density tea leaves have moderate wind resistance. Heavy, dense, or stemmed tea leaves fall onto the middle conveyor belt 8. Heavier, denser tea leaves, or those containing stems, are less affected by the airflow and fall onto the bottom conveyor belt 8 or directly to the bottom. Each conveyor belt 8 is fitted between two rotating rollers and driven by a second pulley 5 at one end. All second pulleys 5 are driven by the initial first pulley 4 via a belt linkage, achieving synchronous transmission. Tea leaves of different grades are transported along their respective conveyor belts 8 to different outlets or collection areas, achieving material zoning processing. The ventilation plate 7, as a grid plate assembly, assists in adjusting the airflow path, enhances the air pressure effect, and also prevents debris from penetrating, protects the conveying area, and facilitates daily maintenance and cleaning.

[0034] Furthermore, such as Figure 1 , 2 3 and Figure 5As shown, the feeding assembly, located above the outer casing 1, is used for directional feeding of tea leaves. It works in conjunction with the sorting assembly to achieve uniform sorting of the tea leaves. The assembly includes a feeding hopper 2, which is fixedly installed on one side of the outer casing 1. The feeding hopper 2 is positioned directly above the feed inlet of the outer casing 1. A third pulley 6 is rotatably mounted on one side of the feeding hopper 2. The third pulley 6 is connected to the first pulley 4 via a belt. A spring 13 is fixedly mounted on one side of the third pulley 6, and an impact hammer 14 is fixedly mounted on the other end of the spring 13. The length of the spring 13 is greater than the distance between the third pulley 6 and the feeding hopper 2. The feeding hopper 2 is fixed above the outer casing 1, directly opposite the feed inlet, a reasonable position that ensures the tea leaves directly enter the sorting area, avoiding spillage or leakage. The third pulley 6 is linked to the first pulley 4 via a belt, achieving unified power source drive, simplifying the transmission system structure, reducing the number of individual drive motors, saving costs and energy consumption, ensuring the feeding rhythm is consistent with the blowing / conveyor actions, and improving the overall machine coordination. One end of the spring 13... The third pulley 6 is connected to the third pulley 6, and the other end is connected to the impact hammer 14, forming an eccentric wheel driving the spring 13 to impact the structure. This can generate intermittent mechanical vibration. As the third pulley 6 rotates, the spring 13 is periodically stretched and released, which drives the impact hammer 14 to make a slight impact on the hopper 2 or its surroundings. This effectively prevents tea leaves from accumulating or getting stuck at the discharge port. It is especially suitable for damp, static-filled, or flaky tea leaves that are easy to bridge, enhancing the smoothness of the discharge and reducing the frequency of manual cleaning. Since the position of the hopper 2 matches the sorting components and has an automatic light impact mechanism, the tea leaves will not fall in large quantities at once, but will be fed evenly and intermittently. This creates a more stable airflow sorting condition for the blower and avoids uneven air pressure in a certain area due to tea leaf accumulation, which would affect the screening effect of the multi-layer conveyor belt 8. As the core component of the transmission, the third pulley 6 does not require additional electrical control or complex encoder control. It achieves its own rhythm function (operating naturally with the transmission rhythm) and perfect synchronization with the main transmission system solely through its mechanical structure.

[0035] Furthermore, such as Figure 1 , 2 3, 4 and Figure 6As shown, the conveying assembly, located inside and on one side of the housing 1, is used for the directional conveying of sorted tea leaves to their respective locations. It includes multiple slide rail bodies 11, which are inserted into the lower part of the housing 1. The number and position of the slide rail bodies 11 correspond to the number and position of the conveyor belts 8. One side of each slide rail body 11 has a slot 15, and the other side has a fixed insert 16. The insert 16 and slot 15 cooperate with each other. The slot 15 is a T-shaped groove, and the insert 16 is a T-shaped block. The slide rail body 11 adopts a "T-shaped insertion structure" of slot 15 and insert 16. The slot 15 is a T-shaped groove, and the insert 16 is a T-shaped protrusion. After insertion, the two automatically limit and prevent detachment, eliminating the need for bolts or other additional fasteners. Assembly is quick and alignment is accurate. In the future, if it is necessary to change the conveying path, adjust the structural height, or maintain the track, it can be quickly plugged in and disassembled, significantly improving efficiency. With high maintenance efficiency and equipment reconfigurability, each slide rail body 11 corresponds to a conveyor belt 8, forming a one-to-one sorting-conveying relationship. During the sorting process, tea leaves falling into different levels of conveyor belts 8 slide down to the corresponding slide rail body 11, ensuring that graded materials do not mix during the conveying process, achieving directional conveying, maintaining the air-separation grading effect until the end, improving the sorting accuracy and traceability of the entire line. Users can replace slide rail bodies 11 with different lengths, materials, or angles as needed to adjust the tea conveying angle, speed, or landing position. It can adapt to different workshop layouts or connect to different packaging / collection equipment, improving the flexibility of the entire line. After the T-shaped insert 16 is inserted into the T-shaped slot 15, it can only slide in and out along the track and cannot sway up and down or be misaligned. It has a self-guiding structural characteristic, reducing assembly errors, ensuring precise docking between the slide rail and the discharge port of the conveyor belt 8, improving the tea guiding efficiency, and reducing the workload of manual debugging.
