Description

Technical Field

[0001] This utility model relates to the field of tea sorting technology, and in particular to a rapid tea leaf sorting device. Background Technology

[0002] The tea production process involves sorting to separate qualified tea from unqualified tea, thus improving the quality of the tea. Tea processing generally includes fresh leaf processing, fixation and shaping, shaping, roasting, and sorting.

[0003] Chinese patent document CN220635161U discloses a tea sorting device. When it is necessary to sift out dust and small tea leaves from freshly picked tea leaves, the fresh leaves can be pre-input into the sieve cylinder through the first and second inlets. Then, the stirring component and the blower are operated simultaneously. The blower blows the tea leaves in the sieve cylinder, and the stirring component stirs the tea leaves. Then, the small, non-compliant tea leaves fall into the shell through the sieve holes. Then, the dust suction mechanism is activated to discharge the small tea leaves from the shell to the outside of the shell, and the dust suction mechanism sucks up the dust raised by the tea leaves. This sorts out non-compliant tea leaves from the fresh tea leaves and reduces the amount of tea leaves attached to the tea leaves. This makes tea sorting more convenient and efficient, allowing for more efficient sorting of smaller tea leaves. At the same time, it reduces the dust on the fresh tea leaves, making the tea leaves cleaner, thus enabling better subsequent processing and improving the taste of the tea.

[0004] The existing technology has the following problems:

[0005] The device directly filters fine tea leaves and gravel through sieve holes, but this method can cause some fine tea leaves and gravel to clog the filter holes, affecting the normal operation of the equipment. However, the device does not have any equipment to clean the materials that clog the filter holes. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, a rapid sorting device for fresh tea leaves includes an outer cover 1, a sieve cylinder 2 movably sleeved on the inner side of the outer cover 1, two fans 3 movably installed on the outer side of the sieve cylinder 2 near the bottom, a cleaning mechanism 4 rotatably connected to the inner side of the outer cover 1, an agitation mechanism 5 movably sleeved on the inner side of the sieve cylinder 2, and two rotating plates 6 rotatably connected on the inner side of the outer cover 1 near the front and rear sides.

[0028] The cleaning mechanism 4 includes a first motor 41, the lower side of which is fixedly connected to the rear side of the outer cover 1 near the upper left side. The output end of the first motor 41 is fixedly connected to two first gears 42 distributed front to back. The front and rear walls of the outer cover 1 are rotatably connected to two second gears 43 distributed front to back. The front and rear sides of the screen cylinder 2 are rotatably connected to two rotating frames 44 distributed front to back near the edge. The two rotating frames 44 are fixedly connected to two cleaning brushes 46 distributed left to right on the left and right sides of the side that is close to each other. The two rotating frames 44 are fixedly connected to two first gear rings 45 distributed front to back near the edge on the side that is far apart from each other.

[0029] It should be noted that the inner side of the rotating plate 6 is fixedly connected to the outer side of the rotating frame 44 to protect the components of the two rotating plates 6 that are far apart from each other. The left and right sides of the outer cover 1 are provided with rotating plates to seal the inner side of the outer cover 1. At the same time, there are interfaces for connecting ventilation pipes to remove dust from the inside of the outer cover 1. The screen cylinder 2 contains components and structures with the same function as those in the reference case. The first motor 41 drives the first gear 42 to rotate. The first gear 42 meshes with the second gear 43, so that the first gear 42 drives the second gear 43 to rotate. The second gear 43 meshes with the first gear ring 45, so that the second gear 43 drives the rotating frame 44 to rotate by the first gear ring 45. When the rotating frame 44 rotates, it drives the cleaning brush 46 to revolve around the screen cylinder 2, so that the cleaning brush 46 cleans the outer side of the screen cylinder 2, thereby clearing the blocked filter holes on the screen cylinder 2.

[0030] like Figure 4As shown, four rectangular rotating rods 47 are rotatably connected to the side of the two rotating frames 44 that are close to each other, near the left and right sides. The inner side of each of the four rotating rods 47 is movably sleeved with a transmission rod 48. The outer side of each of the four transmission rods 48 is fixedly connected to two vertically distributed dial plates 412 near the front and rear sides. Four rectangularly distributed dials 411 are rotatably connected to the side of the two rotating frames 44 that are far apart from each other, near the left and right sides. Four rectangularly distributed third gears 410 are rotatably connected to the side of the two rotating frames 44 that are far apart from each other, near the left and right sides. Two front-to-back distributed second gear rings 49 are fixedly connected to the inner side of the outer cover 1 near the front and rear sides. Several front-to-back distributed striking rods 413 are fixedly connected to the outer side of each of the four rotating rods 47.

[0031] It should be noted that a torsion spring is provided between the rotating rod 47 and the rotating frame 44, and the second gear ring 49 is meshed with the third gear 410. When the rotating frame 44 rotates, it drives the third gear 410 to revolve. Due to the presence of the second gear ring 49, the third gear 410 rotates. The third gear 410 drives the dial 411 to rotate by the fourth gear. When the dial 411 rotates, it pushes the dial plate 412, which drives the transmission rod 48 to rotate. In turn, the transmission rod 48 drives the rotating rod 47 to rotate, so that the striking rod 413 strikes the outside of the screen cylinder 2.

[0032] like Figure 4 As shown, the front and rear ends of the four transmission rods 48 are rotatably connected to connecting plates 416, and the eight connecting plates 416 are fixedly connected to telescopic rods 415 on the side near the screen cylinder 2. The outer sides of the telescopic rods 415 are fixedly connected to the left and right sides of the rotating frame 44.

[0033] It should be noted that the telescopic rod 415 can control its own length, so that the telescopic rod 415 drives the connecting plate 416 to move, which in turn drives the transmission rod 48 to move, so that only one of the two rotating rods 47 located on the same side is driven by the dial plate 412 when rotating clockwise or counterclockwise.

[0034] like Figure 4 As shown, the outer sides of the four transmission rods 48 are provided with spiral grooves 414.

[0035] It should be noted that the spiral groove 414 is designed so that the transmission rod 48 drives the rotating rod 47 to rotate when it moves, thereby causing the striking rod 413 on the rotating rod 47, which is not in use for driving, to move away from the screen cylinder 2.

[0036] like Figure 6 As shown, several striking rods 413 are fixedly connected to rubber pads near the screen cylinder 2.

[0037] It should be noted that the rubber pad is used to prevent the striking rod 413 from making rigid contact with the screen cylinder 2, which would cause deformation of the component. At the same time, the fixing method is to use glue to fix it, which makes it convenient to replace and maintain it.

[0038] like Figure 6 As shown, the stirring mechanism 5 includes a second motor 51. The front side of the second motor 51 is fixedly connected to the middle of the rear side of the outer cover 1. The output end of the second motor 51 is fixedly connected to a stirring frame 52. The outer side of the stirring frame 52 is movably sleeved on the inner side of the sieve cylinder 2. A bearing seat 54 is fixedly connected to the outer side of the stirring frame 52 near the front end. A sealing frame 53 is movably sleeved on the outer side of the bearing seat 54. The outer side of the sealing frame 53 is movably sleeved on the inner side of the front wall of the outer cover 1 and the inner side of the front wall of the sieve cylinder 2. The front side of the sealing frame 53 is fixedly connected to the front side of the outer cover 1 by screws.

[0039] It should be noted that the second motor 51 drives the stirring frame 52 to rotate. The coupling connecting the second motor 51 and the stirring frame 52 is located inside the screen cylinder 2. Removing the sealing frame 53 allows the bearing seat 54 to be separated from the sealing frame 53, making it easy to remove the stirring frame 52 from the second motor 51, thereby enabling quick maintenance inside the screen cylinder 2.

[0040] like Figure 6 As shown, the sealing frame 53 is made of transparent material.

[0041] It should be noted that the rear side of the sealing frame 53 is coated with Teflon to enhance the wear resistance of the rear side of the sealing frame 53 and facilitate cleaning. At the same time, the transparent material allows observation of the inside of the sieve cylinder 2.

[0042] The working principle of this utility model is as follows: First, the first motor 41 drives the first gear 42 to rotate. The first gear 42 meshes with the second gear 43, causing the first gear 42 to drive the second gear 43 to rotate. The second gear 43 meshes with the first gear ring 45, causing the second gear 43 to drive the rotating frame 44 to rotate via the first gear ring 45. When the rotating frame 44 rotates, it drives the cleaning brush 46 to revolve around the screen cylinder 2, causing the cleaning brush 46 to clean the outside of the screen cylinder 2, thus clearing the blocked filter holes on the screen cylinder 2. The rotating rod 47 and the rotating frame 44... A torsion spring is provided, and the second gear ring 49 is meshed with the third gear 410. When the rotating frame 44 rotates, it drives the third gear 410 to revolve. Due to the presence of the second gear ring 49, the third gear 410 rotates. The third gear 410 drives the dial 411 to rotate via the fourth gear. When the dial 411 rotates, it pushes the dial plate 412, which in turn drives the transmission rod 48 to rotate. This causes the transmission rod 48 to drive the rotating rod 47 to rotate, so that the striking rod 413 strikes the outside of the screen cylinder 2. The rotating frame is driven by the first motor 41. Rotation of the rotating frame 44 causes the cleaning brush 46 to clean the outside of the screen cylinder 2. As the rotating frame 44 rotates, the striking rod 413 is driven to rotate and strike the screen cylinder 2, further facilitating the removal of debris clogging the filter holes on the screen cylinder 2. This facilitates equipment maintenance and prevents any impact on the equipment's performance. Finally, the second motor 51 drives the stirring frame 52 to rotate. The coupling connecting the second motor 51 and the stirring frame 52 is located inside the screen cylinder 2. Removing the sealing frame 53 allows the bearing seat 54 to separate from the sealing frame 53, making it easier to install the stirring frame 52. 2. The seal frame 53 is removed from the second motor 51, allowing for quick maintenance of the inside of the screen cylinder 2. The rear side of the seal frame 53 is coated with Teflon to enhance its wear resistance and facilitate cleaning. The transparent material allows observation of the inside of the screen cylinder 2. By observing the inside of the blower 3 through the seal frame 53, it is easy to inspect the condition inside the screen cylinder 2. When necessary, the seal frame 53 can be directly removed, allowing users to quickly maintain the components inside the screen cylinder 2. This avoids the situation where the entire structure is sealed, making it difficult to inspect the internal condition and affecting equipment maintenance.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
