Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea production technology, specifically to an intelligent speed-controlled tea drum sorting device. Background Technology
[0002] Tea refers to the leaves, buds, or stems picked from the tea plant and processed using various techniques. Tea is one of the world's most important beverages, mainly categorized into green tea, black tea, oolong tea, white tea, yellow tea, and dark tea. Tea contains various bioactive substances, such as polyphenols, caffeine, and amino acids, which offer certain health benefits.
[0003] With the development of tea processing technology, intelligently controlled tea drum sorting equipment is being widely used. Currently available sorting equipment cannot completely and evenly disperse tea leaves during the sorting process; some areas have severe tea accumulation, while others are too sparse, affecting the sorting effect and efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent speed-controlled tea drum sorting device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] Intelligent speed-controlled tea drum sorting equipment includes:
[0007] The screen cylinder has openings at both ends to form a feed end and a discharge end;
[0008] The agitation assembly includes multiple agitators arranged annularly within the sieve cylinder, each agitator comprising:
[0009] The fixing rod has one end fixed to the inner wall of the feed end and the other end extending axially along the discharge end, and a gap is formed between the outer wall of the fixing rod and the inner wall of the screen cylinder.
[0010] Elastic swing blades, multiple elastic swing blades are vertically hinged to the outer wall of the fixed rod and arranged at equal intervals along the length of the fixed rod;
[0011] When the sieve cylinder rotates to the working position, the agitator's elastic oscillating blades undergo a complex motion due to the impact of the tea leaves, including:
[0012] Restricted oscillation around the hinge end;
[0013] Elastic deformation along the axial direction of the fixed rod;
[0014] Circumferential asynchronous flutter;
[0015] The composite motion forms a non-periodic disturbance field, causing the tea leaves to produce a three-dimensional spatial dispersion effect. The dispersion intensity is non-linearly positively correlated with the rotational speed of the sieve cylinder.
[0016] Preferably, the length of the elastic swing blade is less than the width of the gap formed between the outer wall of the fixed rod and the inner wall of the screen cylinder.
[0017] Preferably, the agitators are arranged in a ring at equal intervals within the sieve cylinder, forming uniformly spaced mechanical wave-like disturbances.
[0018] Preferably, the agitator is distributed in a ring-shaped, gradually expanding manner within the sieve cylinder, forming a gradient sorting process with gradually decreasing disturbance intensity.
[0019] Preferably, the material of the elastic swing blade is distributed in a radial gradient, with the near hinge end being a polyurethane elastomer and the far hinge end being a nylon composite material, and a silicone rubber buffer layer provided in the transition zone.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This invention incorporates an agitator inside the sieve cylinder.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0028] Example
[0029] like Figures 1-3 As shown, the intelligent speed-controlled tea drum sorting equipment includes:
[0030] Screen cylinder 1 has openings at both ends to form a feed end and a discharge end;
[0031] The agitation assembly includes multiple agitators 2 arranged annularly within the sieve cylinder 1, each agitator 2 comprising:
[0032] The fixing rod 21 has one end fixed to the inner wall of the feed end and the other end extending axially along the discharge end, and a gap is formed between the outer wall of the fixing rod 21 and the inner wall of the screen cylinder 1.
[0033] Elastic swing blades 22, multiple elastic swing blades 22 are vertically and downwardly hinged to the outer wall of the fixed rod 21 and are arranged at equal intervals along the length of the fixed rod 21;
[0034] When the agitator 2 rotates to the working position in the sieve cylinder 1, each elastic oscillating blade 22 undergoes a complex motion due to the impact of the tea leaves, including:
[0035] Restricted oscillation around the hinge end;
[0036] Elastic deformation along the axis of the fixed rod 21;
[0037] Circumferential asynchronous flutter;
[0038] The combined motion creates a non-periodic disturbance field, causing the tea leaves to exhibit a three-dimensional spatial dispersion effect. The dispersion intensity is non-linearly positively correlated with the rotational speed of the sieve cylinder 1.
[0039] Specifically, tea leaves enter the screen cylinder 1 from the feed end. The screen cylinder 1 rotates under the action of the power source in the machine body, and the tea leaves roll forward under the action of rotation. Multiple agitators 2 of the agitation assembly are distributed in a ring inside the screen cylinder 1. When the screen cylinder 1 rotates to the working position (that is, when the agitators 2 enter the tea accumulation area), the elastic oscillating blades 22 are impacted by the tea leaves, generating a compound motion and forming a non-periodic disturbance field, so that the tea leaves are evenly dispersed in three-dimensional space, thereby improving the screening efficiency.
[0040] Furthermore, the compound motion of the elastic oscillating leaf 22 is achieved through the coordinated action of the following three motion modes:
[0041] (1) Restricted oscillation about the hinge end
[0042] Movement mode: The elastic swing blade 22 swings around the hinge point of the fixed rod 21. The swing angle is limited by the mechanical structure (such as the damping mechanism of the hinge technology at the hinge point) to avoid excessive rebound.
[0043] Effects: Provides gentle stirring to prevent tea leaves from breaking; creates non-rigid disturbance to loosen the tea leaf layer.
[0044] (2) Elastic deformation along the axis of the fixed rod 21
[0045] Movement method: Since the elastic swing blade 22 is made of elastic material (such as polyurethane or engineering plastic), when it is impacted by tea leaves, the elastic swing blade 22 bends and deforms along the axis of the fixed rod 21.
[0046] Effects: Absorbs impact energy, reduces tea leaf damage, enhances flexible disturbance, disperses tea leaves in the axial direction, and generates rebound force when the deformation recovers, assisting the tea leaves to flow forward.
[0047] (3) Circumferential asynchronous flutter
[0048] Movement mode: Due to the independent hinge of multiple elastic swing blades 22 and the random variation of the impact force of the tea leaves, the swing of each elastic swing blade 22 is asynchronous, forming a high-frequency micro-amplitude flutter.
[0049] Effects: Breaks up the static accumulation of tea leaves, prevents clumping, generates non-periodic disturbances, avoids uneven sieving caused by resonance, increases the probability of tea leaf tumbling, and fully separates tea leaves of different sizes.
[0050] Formation and effects of non-periodic perturbation fields:
[0051] Disturbance field characteristics: Due to the randomness of the composite motion, the elastic oscillating leaf 22 will not form a fixed trajectory, but will generate chaotic disturbances, so that the tea leaves are uniformly dispersed in three-dimensional space (radial, axial and circumferential).
[0052] Nonlinear speed correlation:
[0053] Low speed (<30rpm): The flexible oscillating leaf 22 provides gentle disturbance, suitable for delicate tea leaves (such as green tea buds);
[0054] Medium to high speed (30-60 rpm): Increased disturbance, suitable for ordinary tea grading;
[0055] High speed (>60rpm): Significant flutter effect, suitable for high-volume sorting, but requires damping control to prevent leaf breakage.
[0056] Furthermore, the length of the elastic swing blade 22 is less than the width of the gap formed between the outer wall of the fixed rod 21 and the inner wall of the screen cylinder 1.
[0057] The system ensures that the flexible oscillating blades 22 do not collide with the inner wall of the sieve cylinder 1 during movement, avoiding mechanical interference and wear. It also allows the flexible oscillating blades 22 to oscillate freely when impacted by tea leaves, improving the flexibility of agitation. The gaps allow the tea leaves to flow smoothly between the flexible oscillating blades 22 and the inner wall of the sieve cylinder 1, reducing the risk of clogging.
[0058] Furthermore, the agitator 2 is distributed in a ring at equal intervals within the screen cylinder 1, forming a uniformly spaced mechanical wave disturbance.
[0059] Mechanism of action:
[0060] (1) Periodic disturbance: The equidistant agitators 2 generate regular mechanical waves when rotating, causing the tea leaves to be evenly dispersed in the sieve cylinder 1.
[0061] (2) Stable sorting: The disturbance intensity remains consistent, which is suitable for conventional tea sorting and ensures the controllability of the screening process.
[0062] (3) Reduce blind spots: Even distribution avoids local accumulation and improves sorting efficiency.
[0063] (4) Applicable scenarios: Suitable for single-variety tea or working conditions with high requirements for sorting uniformity.
[0064] Furthermore, the agitator 2 is distributed in a ring-shaped, gradually expanding manner within the screen cylinder 1 (such as being dense in the initial stage and gradually becoming sparse in the later stage), forming a gradient sorting with gradually weakening disturbance intensity.
[0065] Mechanism of action:
[0066] (1) Gradient perturbation: In the initial stage, high-intensity perturbation quickly breaks up the tea clumps, while in the later stage, low-intensity perturbation avoids excessive rolling and leaf breakage.
[0067] (2) Matching the flow characteristics of tea leaves: When tea leaves are first placed, they are piled up thickly and require stronger disturbance; later, they have been partially screened, so the disturbance can be reduced appropriately.
[0068] (3) Applicable scenarios: Suitable for high-yield continuous sorting or tea density changes.
[0069] Furthermore, the material of the elastic swing blade 22 is distributed in a radial gradient, with the near hinge end being a polyurethane elastomer (flexible and fatigue-resistant), the far hinge end being a nylon composite material (rigid and wear-resistant), and a silicone rubber buffer layer (energy absorption) provided in the transition zone.
[0070] Mechanism of action:
[0071] (1) Flexibility near the hinge end: reduces stress concentration during swing and extends service life.
[0072] (2) Rigidity of the far hinge end: enhances the effect of the leaf tip on tea leaves.
[0073] (3) Transition zone buffer: smoothly transmits impact energy and avoids fracture caused by sudden stress changes.
[0074] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
