Description

Technical Field

[0001] This utility model relates to the field of green tea preparation technology, and in particular to a tea color sorter. Background Technology

[0002] Tea color sorters are high-tech optoelectronic mechanical devices that use the color differences between tea stems, yellow leaves and genuine tea leaves to select tea leaves using high-definition CCD optical sensors. In order to improve the quality of tea, it is often necessary to separate the tea buds and tea stems, but traditional color sorters cannot meet this requirement well.

[0003] Patent CN217616168U discloses a tea color sorter, which includes a feeding hopper. A discharge assembly is installed at the outlet of the feeding hopper. The discharge assembly includes a discharge roller, a discharge motor, and partitions. The discharge motor drives the discharge roller to rotate, causing tea leaves to continuously fall between the two partitions. As the discharge roller rotates, it continuously flips the tea leaves in the feeding hopper to the outlet, thus placing the tea leaves on a conveying device and improving the uniformity of tea conveying. It also includes a leveling assembly, which includes a support base, a leveling shaft, a leveling motor, and leveling paddles. The leveling motor drives the leveling shaft to rotate, causing the leveling paddles to rotate accordingly. When the leveling paddles rotate, they disperse the accumulated tea leaves on the conveying device, spreading them evenly and reducing mutual interference between tea leaves when passing through the separation assembly. This ensures that all tea stems and buds are separated, guaranteeing the quality of the tea.

[0004] While the aforementioned tea color sorter can separate buds and stems, and further improves the separation effect to some extent by evenly spreading the tea leaves, it suffers from the following problems: When the discharge roller flips the tea leaves outside the discharge port, the leaves tend to accumulate near the central axis of the conveying device, resulting in extremely uneven distribution along the width of the device. The spreading component can only spread the tea leaves along the conveying direction, not along the width, thus limiting its dispersing effect. Consequently, the separation of stems and buds is limited, significantly compromising the quality of the tea. Improvement is urgently needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tea color sorter that solves the problem that the distribution of tea leaves in the width direction of the conveying device remains uneven after passing through the discharge component and the flattening component, thus reducing the subsequent separation effect of tea stems and buds.

[0006] According to an embodiment of this utility model, a tea color sorter includes a frame body and a feeding hopper and a conveying device fixedly connected to the frame body. The feeding hopper is provided with a discharge port, and a discharge assembly is provided inside the discharge port. The discharge assembly includes a discharge motor, which is connected to the outer wall of the feeding hopper. It also includes a uniform material distribution assembly, which comprises:

[0007] The material distribution ladder is located below and connected to the discharge port, and material distribution partitions are spaced apart inside it along the width direction of the conveying device.

[0008] A horizontal screen assembly includes a screen frame, which is arranged along the width direction of the conveying device and located between the material distribution ladder and the conveying device; an elastic element is provided between one end of the screen frame along the width direction of the conveying device and the frame body, and the other end of the screen frame abuts against an intermittent pushing mechanism connected to the discharge motor.

[0009] The technical principle of this utility model is as follows: On the one hand, the material distribution partition divides the interior of the material distribution ladder into multiple discharge spaces along the width direction of the conveying device. The tea leaves flipped down by the discharge component enter the multiple discharge spaces respectively, thereby guiding the tea leaves to the corresponding positions of the multiple discharge spaces above the conveying device, so as to improve the uniformity of the tea leaf distribution in the width direction of the conveying device. On the other hand, the discharge motor drives the intermittent pushing mechanism to intermittently push the screen frame towards the elastic element. At this time, the elastic element is compressed. When the pushing force of the intermittent pushing mechanism on the screen frame disappears, the screen frame resets under the elastic force of the elastic element, and is then pushed towards the elastic element again. This cycle repeats, so that the screen frame moves back and forth along the width direction of the conveying device. When the tea leaves in the multiple discharge spaces fall into the corresponding area of ​​the screen frame, the back and forth movement of the screen frame can continue to spread the tea leaves evenly along the width direction of the conveying device. The evenly spread tea leaves then fall onto the conveying device, further ensuring the uniformity of the tea leaf distribution in the width direction of the conveying device.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Improved uniform material distribution. By employing a distribution ladder and a horizontal sieve assembly, the tea leaves tumbled from the discharge assembly undergo an initial diversion along the width of the conveyor, followed by further sieving and uniform distribution. This solves the problem in existing technologies where the tea leaves remain unevenly distributed along the width of the conveyor even after passing through the discharge and flattening assemblies. It ensures better uniformity of tea leaf distribution along the width of the conveyor, thereby ensuring better separation of tea stems and buds, and improving tea production efficiency and quality.

[0012] 2. Energy saving. By connecting the intermittent drive mechanism to the discharge motor, the intermittent drive mechanism is driven by the discharge motor without the need for additional energy, thus giving the tea color sorter of this application the advantages of energy saving and consumption reduction, which is conducive to promotion.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-7As shown in the figure, this utility model embodiment proposes a tea color sorter, including a frame body 100 and a feed hopper 200 and a conveying device 400 fixedly connected to the frame body 100. The feed hopper 200 is provided with a discharge port 210, and a discharge component is provided inside the discharge port 210. The discharge component includes a discharge motor 310, which is connected to the outer wall of the feed hopper 200. It also includes a uniform material distribution component, which includes a material distribution ladder 710 and a horizontal screen group. The components include: the material distribution ladder 710 is located below and connected to the discharge port 210, and material distribution partitions 711 are spaced apart along the width direction of the conveying device 400 inside it; the horizontal screen assembly includes a screen frame, which is arranged along the width direction of the conveying device 400 and is located between the material distribution ladder 710 and the conveying device 400; an elastic element is provided between one end of the screen frame along the width direction of the conveying device 400 and the frame body 100, and the other end of the screen frame abuts against an intermittent pushing mechanism connected to the discharge motor 310.

[0023] In this embodiment, the direction perpendicular to the material conveying direction of the conveying device 400 is defined as the width direction of the conveying device 400. Correspondingly, the longitudinal section of the material distribution ladder cylinder 710 along the width direction of the conveying device 400 is preferably trapezoidal or similar to a trapezoid (e.g., the waist of the trapezoid is changed to an arc). Furthermore, the two side walls of the material distribution ladder cylinder 710 along the material conveying direction of the conveying device 400 are preferably arranged vertically to spread the tea leaves flipped down by the discharge component in the width direction of the conveying device 400, while simultaneously saving material distribution space. The space occupied by the ladder cylinder 710 in the material conveying direction of the conveying device 400; it should also be noted that the size of the material distribution ladder cylinder 710 along the width direction of the conveying device 400 should not be too large to avoid tea leaves falling onto both sides of the conveyor belt; each material distribution partition 711 is connected to the two inner walls of the material distribution ladder cylinder 710 along the material conveying direction of the conveying device 400, and preferably, the ends of the multiple material distribution partitions 711 away from the discharge port 210 are evenly distributed in the width direction of the conveying device 400, while their other ends are arranged in a manner similar to that of the material distribution partitions 711 in the width direction of the conveying device 400. Figure 6 and Figure 7 The uneven distribution shown is addressed by the material distribution partition 711 dividing the interior of the material distribution ladder 710 into multiple discharge spaces 712 along the width direction of the conveying device 400. These multiple discharge spaces 712 can guide the tea leaves to various positions along the width direction of the conveying device 400 to the greatest extent possible, thereby increasing the uniformity of the tea leaf distribution. In addition, the discharge roller 320 is connected to the output end of the discharge motor 310. Preferably, the axis of the discharge roller 320 is parallel to the material conveying direction of the conveying device 400, and the end of the discharge roller 320 away from the discharge motor 310 extends out of the feed hopper 200 to connect with the intermittent push mechanism.

[0024] In this utility model:

[0025] On the one hand, the uniform distribution effect is better. By using the distribution ladder cylinder 710 and the horizontal screen assembly, the tea leaves turned over by the discharge assembly are first divided in the width direction of the conveying device 400, and then further screened in the width direction of the conveying device 400. This solves the problem in the prior art that the distribution of tea leaves is still uneven in the width direction of the conveying device 400 after passing through the discharge assembly and the flat distribution assembly. It ensures that the tea leaves are distributed more evenly in the width direction of the conveying device 400, thereby ensuring a better separation effect of tea stems and buds in the subsequent process, and improving the efficiency and quality of tea production.

[0026] On the other hand, it saves energy. By connecting the intermittent drive mechanism to the discharge motor 310, the intermittent drive mechanism does not require additional energy, thus giving the tea color sorter of this application an energy-saving and consumption-reducing advantage, which is conducive to its promotion.

[0027] like Figures 1-5 As shown, according to another embodiment of the present invention, the intermittent pushing mechanism includes a cam 737 and a transmission mechanism. The cam 737 is horizontally arranged and one end of it abuts against the screen frame. One end of the transmission mechanism is connected to the cam 737, and the other end of it is fixedly connected to the output shaft of the discharge motor 310, so as to convert the rotational motion of the discharge motor 310 in the vertical plane (the rotation axis of the discharge motor 310 is in the horizontal direction) into the rotational motion of the cam 737 in the horizontal plane (the rotation axis of the cam 737 is in the vertical direction). The cam 737 has a simple structure and is easy to implement the intermittent pushing function of the screen frame.

[0028] Furthermore, such as Figures 1-3 As shown, the transmission mechanism includes a first bevel gear 731, a second bevel gear 732, a third bevel gear 733, and a fourth bevel gear 734. The first bevel gear 731 is fixedly connected to the output shaft of the discharge motor 310. Specifically, the output shaft of the discharge motor 310 is connected to the discharge roller 320. The end of the discharge roller 320 away from the discharge motor 310 extends out of the feed hopper 200 and is connected to the first bevel gear 731. The second bevel gear 732 is arranged vertically and is perpendicular to and meshes with the first bevel gear 731. The third bevel gear 733 is parallel to the second bevel gear 732 and is connected to the second bevel gear 732 through a transverse rotating rod 735 connected to the outer wall of the feed hopper 200. The fourth bevel gear 734 is arranged horizontally and is perpendicular to and meshes with the third bevel gear 733. The fourth bevel gear 734 is connected to the cam 737 through a longitudinal rotating rod 736 connected to the transverse rotating rod 735.

[0029] Furthermore, such as Figures 1-5As shown, the screen frame includes two abutment plates 721, which are symmetrically arranged on both sides of the width direction of the distribution ladder 710, where the width direction of the distribution ladder 710 is consistent with the width direction of the conveying device 400. One of the two abutment plates 721 abuts against the cam 737 and the other is connected to the elastic element. The two abutment plates 721 are connected by two connecting bridges 722, and the two connecting bridges 722 are connected by a plurality of screen rods 723 arranged at intervals between the two abutment plates 721. Note that the number of screen rods 723 should be moderate to ensure that the tea leaves can fall smoothly and have a good distribution effect on the tea leaves.

[0030] Based on the above solutions, such as Figures 1-5 As shown, the frame body 100 has two parallel and spaced-apart slides 110. Each slide 110 has a groove 111 along its length at its top. A slide rod 724 is slidably disposed within each groove 111, and the two slide rods 724 are connected to two connecting bridges 722 in a one-to-one correspondence. Preferably, the length of the slide rod 724 is equal to the length of the connecting bridge 722, and the shape of the slide rod 724 is preferably narrower at the top and wider at the bottom. Simultaneously, the shape of the groove 111 is adapted to the slide rod 724, ensuring stable sliding of the slide rod 724 and preventing it from slipping out of the groove 111. An elastic element is provided in each groove 111 and connected to one end of the corresponding slide rod 724. Here, the elastic element is preferably a spring 740. The cooperation between the two sliding rods 724 and the two sliding tables 110 not only makes the structure simple and stable, but also ensures that the screen frame moves stably in the width direction of the conveying device 400, thereby ensuring that the screen rods 723 have a good distribution effect on the tea leaves.

[0031] When using this embodiment:

[0032] The discharge roller 320 rotates, driving the first bevel gear 731 to rotate in the first vertical plane. The second bevel gear 732 transmits the rotation of the first bevel gear 731 in the first vertical plane to a second vertical plane perpendicular to the first vertical plane. Then, the third bevel gear 733 transmits the rotation of the second bevel gear 732 in the second vertical plane parallel to a third vertical plane away from the feed hopper 200. The fourth bevel gear 734 then transmits the rotation of the third bevel gear 733 in the third vertical plane to a fourth horizontal plane perpendicular to the third vertical plane. Finally, the cam 737 transmits the rotation of the fourth bevel gear 734 in the fourth horizontal plane parallel to the horizontal plane where the cam 737 is located. Thus, through the mutual cooperation of the above four bevel gears, the rotational motion of the discharge motor 310 in the vertical plane (the rotation axis of the discharge motor 310 is in the horizontal direction) is converted into the rotational motion of the cam 737 in the horizontal plane (the rotation axis of the cam 737 is in the vertical direction). When cam 737 rotates, when the end of cam 737 furthest from its rotation axis begins to abut against the corresponding abutment plate 721, it applies a thrust towards spring 740 to the abutment plate 721. The abutment plate 721 then drives slide rod 724 to slide closer to spring 740 within slide groove 111, thereby moving the entire screen frame closer to spring 740 until the point on cam 737 furthest from its rotation axis abuts against the corresponding abutment plate 721. Then, cam 737 continues to rotate, and the end of cam 737 furthest from its rotation axis begins to move away from the corresponding abutment plate 721, creating a gap between cam 737 and abutment plate 721. At this point, the abutment plate connected to spring 740... 721 begins to move away from spring 740 under the elastic force of spring 740, thereby driving slide bar 724 to slide away from spring 740 in slide groove 111, thus causing the entire screen frame to move away from spring 740 until it stops when the other point on cam 737 opposite to the point farthest from its rotation axis abuts against the corresponding abutment plate 721, at which point the screen frame resets; then cam 737 continues to rotate, and with the elastic force of spring 740, the screen frame moves back and forth along the width direction of conveying device 400, thereby causing screen bar 723 to move back and forth in the direction perpendicular to the falling tea leaves to push the tea leaves to be evenly distributed along the width direction of conveying device 400.

[0033] like Figure 6 and Figure 7As shown, according to another embodiment of the present invention, and in conjunction with the preferred arrangement of the material distribution partition 711 described above, it is further preferred that there are three material distribution partitions 711, and each material distribution partition 711 is arranged at an angle. Thus, the material distribution partitions 711 divide the interior of the material distribution ladder 710 into four discharge spaces 712 along the width direction of the conveying device 400, and the four discharge spaces 712 can guide the tea leaves to various positions along the width direction of the conveying device 400 to the greatest extent possible, thereby increasing the uniformity of tea leaf distribution. In addition, the angled arrangement of the material distribution partitions 711 can also improve the guiding effect of the tea leaves, while better protecting the shape of the tea leaves.

[0034] Based on the above solutions, such as Figure 7 As shown, the side wall of the material distribution partition 711 is arc-shaped, and correspondingly, the two side walls of the material distribution ladder 710 along the width direction of the conveying device 400 are also arc-shaped. The arc-shaped design allows the tea leaves to be spread out to the maximum extent along the width direction of the conveying device 400 when they pass through each of the discharge spaces 712, which not only improves the space utilization rate but also improves the uniformity of tea leaf distribution.

[0035] like Figure 1 As shown, according to another embodiment of the present invention, the tea color sorter further includes a separation device, which includes a slide 510, a baffle 520 disposed within the slide 510, and a nozzle 530 disposed on one side of the slide 510 to spray tea leaves discharged from the discharge port 410 of the conveying device 400 onto the baffle 520; wherein, in the prior art, the baffle 520 is arranged vertically (see patent CN217616168U for details, which will not be repeated here), and the spray direction of the nozzle 530 is perpendicular to it. When the tea leaves are sprayed vertically onto the baffle 520, some tea leaves, buds, and tea stems are propelled to a higher position by the reaction force of the baffle 520, and when they fall, they are easily mixed with the newly sprayed tea leaves. The separation effect of the new batch of buds and tea stems is affected, and the quality of tea leaves, buds and tea stems is also affected by the secondary spray from the jet nozzle 530. Based on this, in the preferred embodiment of the present invention, the baffle 520 is inclined and the distance between it and the conveying device 400 gradually increases from its upper end to its lower end. This makes the reaction force of the baffle 520 on the tea leaves sprayed on it and the newly separated buds and tea stems mainly concentrated in the downward direction. As a result, each batch of tea leaves, buds and tea stems sprayed on it tends to fall rather than rush to a higher position. This solves the above-mentioned problems of the vertically arranged baffle 520 in the prior art, greatly improves the efficiency and effect of bud and tea stem separation, and improves the quality of tea.

[0036] Furthermore, such as Figure 1As shown, the separation device further includes a guide hopper 540, which is connected between the feed inlet 511 and the discharge outlet 410 of the slide 510. Specifically, the opening of the guide hopper 540 is located on the bottom side of the corresponding end of the conveying device 400, and extends as close as possible to the conveying device 400 to maximize the collection of tea leaves on the conveying device 400. In addition, the bottom of the guide hopper 540 is narrow and inclined to better guide the tea leaves falling from the conveying device 400 to the spray range of the jet nozzle 530, further improving the tea leaf separation effect. Furthermore, preferably, this embodiment is a further optimization based on the aforementioned embodiments.

[0037] When using:

[0038] After tea leaves are fed into the feed hopper 200, they fall into the discharge port 210. The discharge motor 310 drives the discharge roller 320 to rotate, which in turn drives the partition 330 on it to rotate, causing the tea leaves to continuously fall between the two partitions 330. As the partitions 330 rotate, the tea leaves are flipped out of the discharge port 210. The flipped tea leaves then fall evenly into the four discharge spaces 712 in the distribution ladder cylinder 710, and the four discharge spaces 712 guide the tea leaves evenly to various positions in the width direction of the conveying device 400. Finally, the tea leaves fall from the four discharge spaces 712 into the area where the screen rod 723 is located. Through the mutual cooperation of the aforementioned four bevel gears, the rotational motion of the discharge motor 310 in the vertical plane (the rotation axis of the discharge motor 310 is in the horizontal direction) is converted into the rotational motion of the cam 737 in the horizontal plane (the rotation axis of the cam 737 is in the vertical direction). When the cam 737 rotates, it intermittently impacts the abutment plate 721. A thrust is applied, and combined with the elastic force of the spring 740 on the abutment 721, the sieve frame moves back and forth along the width direction of the conveying device 400. This causes the sieve rod 723 to move back and forth in a direction perpendicular to the falling tea leaves, further pushing the tea leaves to be evenly distributed along the width direction of the conveying device 400. The tea leaves then fall onto the conveying device 400, where they are evenly distributed along the width direction. The tea leaves then enter the guide hopper 540 from the discharge port 410 of the conveying device 400. After being guided by the guide hopper 540, the tea leaves fall precisely from the feed port 511 of the slide 510 into the spray range of the corresponding air nozzle 530. The tea leaves are then sprayed onto the inclined baffle 520, where the impact causes the buds and stems to separate. The separated tea leaves, under the reaction force of the baffle 520 pointing downwards, fall through the slide 510 into the subsequent sieving device 600 for further processing.

[0039] It should be noted that the basic structure of the tea color sorter in this application is basically the same as that of the existing tea color sorter. It mainly consists of the frame body 100, the feed hopper 200, the discharge port 210, the discharge assembly, the conveying device 400, the separation device, and the sieving device 600. The discharge roller 320 and the partition plate 330 are located in the discharge assembly, and the slide 510, the baffle 520, and the air nozzle 530 are located in the separation device. For details, please refer to patent CN217616168U, which will not be repeated here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
