[0004] The aforementioned organic tea leaf color sorting device proposes that by setting up a material distribution component, the material can be diverted. When one set of receiving boxes is full, the material is guided to another set of receiving boxes for collection. The full set of receiving boxes can be used for storage and packaging. However, during use, some tea leaves will adhere to the conveyor belt and need to be cleaned, which may result in waste of tea leaves. Utility Model Content

[0005] The purpose of this invention is to provide a tea color sorting and grading conveyor device to solve the problem that existing tea color sorting and grading conveyor devices are difficult to clean the conveyor belt.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tea color sorting and grading conveying device, including a base;

[0007] A workbench is mounted on the top of the base, a box is mounted on one side of the workbench, and a mounting bracket is mounted on the top of the workbench.

[0008] The mounting frame is equipped with a conveyor belt, and a box is installed at the top of the conveyor belt. A vision selection module is installed at the top of the box, and a channel is installed at the top of the workbench.

[0009] A cleaning mechanism is installed at the bottom of the workbench. The cleaning mechanism includes a bellows at the bottom of the workbench, a fan at the bottom of the bellows, and a trough at the top of the bellows.

[0010] In use, tea leaves can first be placed on the top of the conveyor belt. The conveyor belt will move the tea leaves. After the tea leaves move into the box, the vision selection module will identify the color of the tea leaves. After identification, it can issue a model number and then control the hydraulic cylinder to work. The hydraulic cylinder will move the push plate. The movement of the push plate and the inclined plane will guide the moving tea leaves, allowing them to move along the inclined plane and the push plate into different channels, and then into different boxes for storage and classification.

[0011] Furthermore, a sorting structure is installed at the top of the workbench. The sorting structure includes mounting plates at both ends of the top of the workbench. A hydraulic cylinder is installed at one end of the mounting plate, and a hydraulic rod is installed at one end of the hydraulic cylinder. A push plate is installed at one end of the hydraulic rod, and an inclined surface is installed on one side of the push plate. The sorting structure can adjust the position of the tea leaves so that they can enter different pipes.

[0012] Furthermore, a moving mechanism is installed at the top of the housing. The moving mechanism includes a servo motor installed on one side of the top of the housing, a threaded rod installed on one side of the servo motor, and a moving block installed on the outer side of the threaded rod. The moving mechanism can adjust the position of the visual selection module.

[0013] Furthermore, guide rods extend through both ends of the movable block, and the guide rods are symmetrically distributed about the central axis of the movable block. The guide rods can prevent the movable block from deviating when it moves.

[0014] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the moving block is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the moving block are threadedly connected, and the rotation of the threaded rod can drive the moving block to move.

[0015] Furthermore, a connecting plate is installed at the bottom of one side of the trough, and a spring is installed at the top of the connecting plate. A scraper is installed at the top of the spring. A drawer is installed inside the air box, and a screen is installed at the bottom of the drawer. When the fan is working, it can suck the scraped tea leaves into the air box.

[0016] Furthermore, the inner diameter of the bellows is larger than the outer diameter of the drawer, and the bellows and the drawer form a sliding structure, allowing the drawer to be pulled out.

[0017] The advantages of the tea color sorting and grading conveyor device provided by this utility model are as follows: during use, the conveyor belt can move the tea leaves, the tea leaves can be classified by the classification structure, allowing the tea leaves to enter different boxes, the visual selection module can be moved by the moving mechanism, allowing the visual selection module to adapt to different situations, and the surface of the conveyor belt can be cleaned by the cleaning mechanism.

[0018] A trough is installed at the bottom of the workbench. The connecting plate and scraper inside the trough are connected by a spring. The elasticity of the spring will cause the buckle to press against the bottom of the conveyor belt. When the conveyor belt passes the scraper, the scraper can scrape the tea leaves off the conveyor belt. Then, the blower will generate suction, which will suck the tea leaves into the drawer inside the blower box. The screen has holes to prevent tea leaves from entering the blower. When the tea leaves need to be processed, the drawer can be pulled out to process the tea leaves inside. This achieves the purpose of cleaning the conveyor belt of the tea color sorting and grading conveyor device.

[0019] By installing a servo motor at the top of the housing, the servo motor drives the threaded rod to rotate. The threaded rod and the moving block form a threaded connection. The rotation of the threaded rod drives the moving block to move, and the movement of the moving block drives the visual selection module fixed at the bottom to move. The movement of the visual selection module allows it to adapt to different situations. It can move back and forth repeatedly to scan the tea leaves at the bottom, making the scanning effect better. This achieves the purpose of making it easy to adjust the position of the visual selection module in the tea color sorting and grading conveying device. Attached Figure Description

[0027] Please see Figures 1-5 One embodiment of this utility model is a tea color sorting and grading conveying device, which includes a base 5.

[0028] A workbench 3 is installed at the top of the base 5. A sorting structure 10 is installed at the top of the workbench 3. The sorting structure 10 includes mounting plates 1005 at both ends of the top of the workbench 3. A hydraulic cylinder 1001 is installed at one end of the mounting plate 1005, and a hydraulic rod 1002 is installed at one end of the hydraulic cylinder 1001. A push plate 1003 is installed at one end of the hydraulic rod 1002, and an inclined surface 1004 is installed on one side of the push plate 1003.

[0029] See attached document Figure 1-2 and attached Figure 4 As shown, tea leaves can be placed at the top of conveyor belt 1. When conveyor belt 1 operates, it will move the tea leaves. After the tea leaves move into the box 6, the vision selection module 4 will identify the color of the tea leaves. The vision selection module 4 identifies the color differences of the tea leaves through a high-precision optical sensor or camera. The high-speed camera captures images of the tea leaves and transmits them to the processing system in real time. After identification, the system can issue a model number and then control the hydraulic cylinder 1001 to operate. The operation of the hydraulic cylinder 1001 will cause the hydraulic rod 1002 to extend and retract. The extension and retraction of the hydraulic rod 1002 will cause the push plate 1003 to move. The movement of the push plate 1003 and the inclined plane 1004 will guide the moving tea leaves, allowing them to move along the inclined plane 1004 and the push plate 1003 into different channels 9, and then into different boxes 8 for storage and classification.

[0030] A box 8 is installed on one side of the workbench 3, and a mounting bracket 2 is installed on the top of the workbench 3.

[0031] The mounting frame 2 has a conveyor belt 1 installed inside, and a box 6 is installed at the top of the conveyor belt 1. A moving mechanism 11 is installed at the top of the box 6. The moving mechanism 11 includes a servo motor 1101 installed on one side of the top of the box 6, and a threaded rod 1102 installed on one side of the servo motor 1101. External threads are evenly provided on the outer side wall of the threaded rod 1102, and internal threads that cooperate with the external threads are evenly provided on the inner side wall of the moving block 1104. The threaded rod 1102 and the moving block 1104 are threadedly connected.

[0032] A movable block 1104 is installed on the outer side of the threaded rod 1102. Guide rods 1103 pass through both ends of the movable block 1104. The guide rods 1103 are symmetrically distributed about the central axis of the movable block 1104.

[0033] See attached document Figure 2 and attached Figure 5 As shown, the servo motor 1101 drives the threaded rod 1102 to rotate. The threaded rod 1102 and the moving block 1104 form a threaded connection. The rotation of the threaded rod 1102 drives the moving block 1104 to move. The movement of the moving block 1104 drives the visual selection module 4 fixed at the bottom to move. The movement of the visual selection module 4 allows it to adapt to different situations. It can move back and forth repeatedly to scan the tea leaves at the bottom, making the scanning effect better. The guide rod 1103 passes through the moving block 1104 and can prevent the moving block 1104 from deviating.

[0034] A vision selection module 4 is installed at the top inside the housing 6, and a channel 9 is installed at the top of the workbench 3.

[0035] A cleaning mechanism 7 is installed at the bottom of the workbench 3. The cleaning mechanism 7 includes a bellows 705 installed at the bottom of the workbench 3.

[0037] See attached document Figure 2-3As shown, the connecting plate 703 and scraper 701 inside the tank 704 are connected by a spring 702. The elasticity of the spring 702 will cause the buckle to press against the bottom of the conveyor belt 1. When the conveyor belt 1 passes through the scraper 701, the scraper 701 can scrape the tea leaves off the conveyor belt 1. Then the blower 706 will work to generate suction. The suction generated by the blower 706 will suck the tea leaves into the drawer 708 inside the blower box 705. The screen 707 is provided with holes. The screen 707 can prevent the tea leaves from entering the blower 706. When the tea leaves need to be processed, the drawer 708 can be pulled out to process the tea leaves inside.
