Description

Technical Field

[0001] This application relates to the technical field of rock tea preparation equipment, and in particular to a tea sorting machine. Background Technology

[0002] Rock tea, a traditional Chinese famous tea, belongs to the oolong tea category. It possesses the fragrance of green tea and the mellow sweetness of black tea, making it the finest among Chinese oolong teas. After the rock tea is harvested, it needs to be winnowed using a tea sorting machine to remove impurities such as sand, yellow leaves, and dust.

[0003] The existing Chinese utility model patent document with publication number CN202778958U discloses a tea sorting machine, which includes a machine body, a fan installed on the machine body, and multiple discharge ports. Tea leaves are added into the machine body from the feed hopper, and the air blown by the fan is blown into the machine body through the air inlet pipe. The tea leaves can be sorted by air force.

[0004] In this design, a baffle is slidably installed on the feed hopper to feed the tea leaves. However, when the baffle slides to feed the tea leaves, the tea leaves fall into the machine in clumps, which can easily affect the sorting effect when the air is used for sorting. Summary of the Invention

[0005] To improve the sorting effect of tea leaves, this application provides a tea sorting machine.

[0006] The technical solution adopted in this application is as follows: A tea sorting machine includes a body, a blower connected to the body, and a feed hopper mounted on the body. A partition for opening and closing the feed hopper is horizontally slidably mounted on the feed hopper. A support plate is rotatably mounted in the body, located directly below the feed hopper and above the air outlet in the body. The support plate and the partition are linked. When the partition opens the feed hopper, the support plate can rotate to a horizontal position. When the partition closes the feed hopper, the support plate can rotate to a downward tilting position towards the inner cavity of the machine.

[0007] By adopting the above technical solution, the material receiving plate is located below the feed hopper. When the partition is open, the material receiving plate can rotate to a horizontal state, and the tea leaves in the feed hopper can fall onto the material receiving plate. When the partition closes the feed hopper, the material receiving plate rotates to an inclined state, allowing the tea leaves to slide into the machine body. Under the action of wind, the screening of tea leaves becomes more effective, thereby improving the tea sorting effect.

[0008] Optionally, two frames are symmetrically installed on the inner wall of the machine body. The material support plate is rotatably connected between the two frames. Rotating shafts are installed on both sides of the material support plate. The rotating shafts rotatably pass through the frames, and synchronous pulleys are installed on the outer walls of the rotating shafts. A drive wheel is also rotatably installed on the frame. A first synchronous belt is installed between the synchronous pulley and the drive wheel. A gear is also rotatably installed on the inner wall of the machine body. A rack is installed on the lower surface of the partition. A second synchronous belt is installed between the gear and the drive wheel. When the partition slides, the rack can mesh with the gear.

[0009] By adopting the above technical solution, when the partition slides, the gear and rack mesh, so that the gear can drive the wheel to rotate through the second synchronous belt, and the wheel drives the synchronous wheel to rotate through the first synchronous belt, so that the material support plate can rotate synchronously with the sliding of the partition.

[0010] Optionally, an elastic element is installed on the inner wall of the machine body, and one end of the material support plate can abut against the elastic element. A limit rod is connected between the ends of the two frames near the inner cavity of the machine body. When the partition slides into the feed hopper, the gear and the rack disengage, and the elastic element can drive one end of the material support plate to move upward, so that the lower surface of one end of the material support plate abuts against the limit rod, and the material support plate forms a state of tilting downward towards the inner cavity of the machine body. When the partition slides out of the feed hopper to drive the material support plate to rotate to a horizontal state, the elastic element is compressed by the material support plate.

[0011] By adopting the above technical solution, limit rods are set between the frames. The material support plate rotates to abut against the limit rods, thereby limiting the rotation angle of the material support plate. Under the action of the elastic element, one end of the material support plate can be driven to move upward, so that the material support plate is stably abutted against the limit rods, making the material support plate more stable during the feeding process. When the partition slides into the feed hopper, the gear and rack disengage, and the elastic element continues to drive the material support plate to move upward, causing one end of the material support plate to hit the limit rods, which facilitates the tea leaves on the material support plate to slide towards the machine body.

[0012] Optionally, the inner wall of the machine body is provided with an installation groove, and the elastic element includes a first spring vertically installed in the installation groove and an abutment block connected to the upper end of the first spring. One end of the abutment block has a portion that extends beyond the inner wall of the machine body, and the abutment block can abut against the lower surface of one end of the material support plate.

[0013] By adopting the above technical solution, the contact block abuts against the lower surface of the support plate. When the support plate is in a horizontal state, the first spring is compressed, thereby providing elastic force for one end of the support plate to move upward.

[0014] Optionally, the mounting groove has a constricted structure.

[0015] By adopting the above technical solution, the mounting groove has a constricted structure, and after the first spring is installed in the mounting groove, the first spring is not easy to detach from the mounting groove.

[0016] Optionally, a rotating rod is rotatably installed in the feed hopper, and a power source for driving the rotating rod to rotate is installed on the outer wall of the feed hopper.

[0017] By adopting the above technical solution, tea leaves can easily accumulate in the feed hopper. When the power source drives the rotating rod to rotate, it can help the tea leaves in the feed hopper fall onto the receiving plate, thereby improving the smoothness of feeding.

[0018] Optionally, the upper surface of the support plate is provided with flanges on both sides, and the length direction of the flanges is parallel to the length direction of the frame.

[0019] By adopting the above technical solution, baffles are provided on both sides of the material support plate, so that when tea leaves fall onto the material support plate, they are not easy to fall off the sides of the material support plate.

[0020] Optionally, the feed hopper is provided with a sliding groove, the partition is horizontally inserted into the slot, and a driving component is installed on the outer wall of the feed hopper. The driving component is connected to the partition to drive the partition to slide back and forth.

[0021] By adopting the above technical solution, the driving component drives the partition to slide back and forth, thereby controlling the opening and closing of the feed hopper and facilitating the feeding of tea leaves.

[0022] In summary, this application includes at least one of the following beneficial effects: 1. The tea leaves first fall onto the receiving plate. After the receiving plate is rotated to an inclined state, the tea leaves slide down from the receiving plate. Under the action of the wind, it is easier to sort out the dead leaves and other parts of the tea leaves. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a tea sorting machine. (Refer to...) Figure 1 and Figure 2 The tea sorting machine includes a body 1, a blower 2 installed at one end of the body 1, and a feed hopper 3 installed at the top of the body 1. The feed hopper 3 is connected to the inner cavity of the body 1, and the blower 2 is connected to one side of the body 1 through an air pipe. Tea leaves enter the body 1 through the feed hopper 3, and the airflow generated by the blower 2 sorts the tea leaves. Multiple discharge ports are provided at the bottom of the body 1 for discharging and collecting the sorted tea leaves.

[0027] Reference Figure 2 and Figure 3 A partition 4 is horizontally slidably mounted on the feed hopper 3, and the partition 4 is used to open and close the feed hopper 3. When feeding is required, the partition 4 slides out of the feed hopper 3, and the tea leaves in the feed hopper 3 can fall into the machine body 1. When the feed hopper 3 needs to be closed, the partition 4 slides into the feed hopper 3, thereby preventing the tea leaves from falling into the machine body 1. Furthermore, a sliding groove 20 is opened on the side wall of the feed hopper 3, and the sliding groove 20 is opened through the side of the feed hopper 3 near the blower 2, and the sliding groove 20 is connected to the inner cavity of the feed hopper 3. The partition 4 is horizontally inserted into the sliding groove 20. A driving component 21 is also installed on the outer wall of the feed hopper 3, and the driving component 21 is used to drive the reciprocating sliding of the partition 4, thereby realizing the opening and closing of the feed hopper 3. Preferably, the driving component 21 is a cylinder. Two cylinders are provided and symmetrically fixed to the outer wall of the feed hopper 3. The piston rod of the cylinder is connected to the end of the partition 4. The partition 4 can be driven to slide horizontally on the feed hopper 3 by the cylinder.

[0028] Reference Figure 2 and Figure 4A material support plate 5 is rotatably installed on the inner wall of the machine body 1. The material support plate 5 is located directly below the discharge port of the feed hopper 3 and above the air blowing position in the machine body 1. The area of ​​the material support plate 5 is larger than the area of ​​the lower outlet of the feed hopper 3. The partition plate 4 and the material support plate 5 can be linked. When the partition plate 4 slides outward from the feed hopper 3, the material support plate 5 can rotate to a horizontal state, and the tea leaves in the feed hopper 3 can fall onto the material support plate 5. When the partition plate 4 slides back into the feed hopper 3, the material support plate 5 can rotate to a state tilted downward towards the inner cavity of the machine body 1. Therefore, the tea leaves on the material support plate 5 can slide down along the material support plate 5 and fall into the machine body 1. At this time, when the airflow sorts the tea leaves, the tea leaves are not easy to accumulate together, and the contact area with the tea leaves is larger, thus improving the sorting effect of the tea leaves. In order to make the tea leaves fall more easily from the material support plate 5 into the machine body 1, the surface of the material support plate 5 can be a smooth surface.

[0029] Reference Figure 2 and Figure 4 Two frames 6 are fixedly installed on the inner wall of the machine body 1. The frames 6 are horizontally arranged, and the material support plate 5 is rotatably installed between the two frames 6. Rotating shafts 7 are symmetrically fixed on both sides of the material support plate 5, and the rotating shafts 7 are rotatably installed on the frames 6 via bearings. There is a gap between the side of the frame 6 away from the material support plate 5 and the inner wall of the machine body 1. One end of the rotating shaft 7 extends beyond the surface of the frame 6 and is coaxially fixed with a synchronous pulley 8. A drive wheel 9 is also rotatably installed on the frame 6, and a first synchronous belt 10 is installed between the synchronous pulley 8 and the drive wheel 9. A gear 11 is rotatably installed on the upper end of the machine body 1. The gear 11 is rotatably installed on the side wall of the feed hopper 3 via a round shaft, and a second synchronous belt 13 is connected between the gear 11 and the drive wheel 9. A round wheel is coaxially fixed on the gear 11 to provide the connection position for the second synchronous belt 13. An opening is provided on the machine body 1 corresponding to the position of the second synchronous belt 13 to provide space for the movement of the second synchronous belt 13. Part of the partition 4 is located outside the feed hopper 3, and a rack 12 is mounted on its lower surface. The rack 12 is located outside the feed hopper 3. When the partition 4 slides, the rack 12 can mesh with the gear 11. In other embodiments, a bearing seat can also be fixed on the upper surface of the machine body 1, and the gear 11 can be rotatably mounted on the bearing seat.

[0030] When the partition plate 4 slides out of the feed hopper 3, the rack 12 and the gear 11 mesh, the gear 11 rotates and drives the drive wheel 9 to rotate through the second synchronous belt 13, and the drive wheel 9 drives the synchronous wheel 8 to rotate through the first synchronous belt 10, so that the material support plate 5 can rotate to a horizontal state. When the partition plate 4 slides into the feed hopper 3, the material support plate 5 rotates to an inclined state.

[0031] Reference Figure 2 and Figure 5An elastic element 14 is installed on the inner wall of the machine body 1, and the lower surface of the material receiving plate 5 near the blower 2 can abut against the elastic element 14. A limit rod 15 is fixed between the ends of the two frames 6 away from the inner wall of the machine body 1, and the limit rod 15 is set horizontally. When the material receiving plate 5 rotates to a horizontal state, the elastic element 14 is compressed by the material receiving plate 5. When the partition plate 4 slides into the feed hopper 3, after the rack 12 and gear 11 disengage, the elastic force of the elastic element 14 can continue to drive one end of the material receiving plate 5 to move upward, and cause the lower surface of the other end of the material receiving plate 5 to hit the limit rod 15. Under the action of the elastic element 14, the material receiving plate 5 can be driven to abut against the limit rod 15 to maintain the tilted state of the material receiving plate 5. When the material receiving plate 5 hits the limit rod 15, the tea leaves on the material receiving plate 5 can slide better into the machine body 1, thereby promoting the sorting of tea leaves. Furthermore, upwardly extending guardrails 19 are fixed on both sides of the material support plate 5. The length direction of the guardrails 19 is parallel to the length direction of the frame 6, so that the tea leaves are not easy to fall from both sides of the material support plate 5.

[0032] A mounting groove 16 is formed on the inner wall of the machine body 1. The mounting groove 16 is arranged vertically and extends to the surface of the inner wall of the machine body 1. The elastic element 14 includes a first spring 141 installed in the mounting groove 16 and an abutment block 142 fixed to the upper end of the first spring 141. The abutment block 142 extends out from the mounting groove 16, so that the lower surface of the support plate 5 can abut against the abutment block 142. The cross-section of the mounting groove 16 is a constricted structure, so that the first spring 141 is not easily dislodged from the mounting groove 16. In order to increase the force on the support plate 5, two mounting grooves are formed, and elastic elements 14 are installed in both of them.

[0033] In a further embodiment, refer to Figure 3 A rotating rod 17 is installed in the feed hopper 3, and a power source 18 for driving the rotating rod 17 to rotate is installed on the outer wall of the feed hopper 3. The power source 18 is preferably an electric motor. During feeding, the rotating rod 17 rotates, making it easier for the tea leaves in the feed hopper 3 to fall downwards and prevent them from accumulating in the feed hopper 3. To further improve the feeding effect, brush bristles can also be fixed to the outer wall of the rotating rod 17.

[0034] The implementation principle of a tea sorting machine according to an embodiment of this application is as follows: the drive partition 4 slides out of the feed hopper 3, the support plate 5 rotates to a horizontal state, and the tea leaves fall onto the support plate 5 during this process. The partition 4 slides into the feed hopper 3, the support plate 5 starts to rotate to an inclined state, and when the rack 12 and gear 11 disengage, the elastic element 14 drives the support plate 5 to continue moving and impact the limit rod 15, so that the tea leaves on the support plate 5 fall better from one end of the support plate 5 into the machine body 1, thereby better sorting.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
