Description

Technical Field

[0001] The present application relates to the technical field of tea screening, and in particular to a screening mechanism for fresh tea leaves. Background Art

[0002] Fresh tea refers to the tea made from the first few batches of fresh leaves picked from tea trees in the spring of that year. In order to make it fresh and tender, some tea farmers start picking tea before the Qingming Festival. Such tea is called Mingqian tea; tea picked before the Guyu solar term is called Yuqian tea. Tea, commonly known as tea, generally includes leaves and buds of tea trees. Tea ingredients include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages made from tea are one of the three major beverages in the world. When fresh tea leaves are picked from the tree, they need to be initially picked and screened out of the residual leaves, old leaves, and mixed branches in the fresh tea leaves. At present, the picked fresh leaves are usually spread flat in bamboo containers by hand, and then selected manually. This method is time-consuming and has poor work efficiency. It is often easy to miss through human naked eye observation, and the residual leaves and debris laid at the bottom are difficult to remove, which easily affects the taste of subsequent tea.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

The present application provides a screening mechanism for fresh tea leaves.

[0005] The present application provides a fresh tea screening mechanism that adopts the following technical solution:

[0006] A screening mechanism for fresh tea leaves comprises a tea screening box, a screening filter for screening tea leaves is clamped in the middle of the inner wall of the tea screening box, a support base is rotatably provided in the middle of the bottom end of the tea screening box, a vibration motor is fixedly connected to the bottom of the tea screening box, support frames are symmetrically provided on both sides of the tea screening box, and movable blocks that provide supporting force on both sides of the tea screening box are movably connected in the support frames.

[0008] Preferably, movable cavities adapted to the movable blocks are provided inside the two support frames, connecting slides are symmetrically fixed to the middle of the side walls of the movable blocks, and inner grooves adapted to the connecting slides are symmetrically provided on the inner walls of the movable cavities.

[0009] Preferably, buffer springs for support are connected between the movable block and the inner walls at both ends of the movable cavity, and rubber pads are bonded and connected to the middle parts of both ends of the movable block.

[0010] Preferably, a screening chamber is provided inside the tea screening box, a debris removal chamber is symmetrically provided at the bottom end of the inner wall of the screening chamber, a guide slope is provided inside the debris removal chamber, and both sides of the bottom of the tea screening box are fixedly connected with discharge pipes.

[0018] The following is combined with Figure 1-3This application is described in further detail.

[0019] The present application embodiment discloses a screening mechanism for fresh tea leaves. Figure 1 , including a tea screening box 1, a screening filter 13 for screening tea leaves is clamped in the middle of the inner wall of the tea screening box 1, and the aperture of the screening filter 13 is set to a size that does not allow standard tea leaves to pass through. A supporting base 3 is provided in the middle of the bottom end of the tea screening box 1, and a connecting plate 6 is welded to the top of the supporting base 3 in an integrated structure. The tea screening box 1 is rotatably connected to the connecting plate 6, so the tea screening box 1 can produce a small angle adjustment in the supporting base 3, and a vibration motor 16 is fixedly connected to the bottom of the tea screening box 1. The vibration motor 16 is located in the middle of the supporting base 3 and has strong protection. The vibration motor 16 can generate mechanical excitation force when it works and transmit it to the tea screening box 1, thereby promoting the screening of fresh tea leaves in the tea screening box 1.

[0020] Reference Figure 1-Figure 2 , support frames 2 are symmetrically arranged on both sides of the tea screening box 1, and movable blocks 4 that provide supporting force on both sides of the tea screening box 1 are movably connected inside the support frames 2, and the inner wall of the movable block 4 is fixedly connected with a connecting shaft 11, and the connecting shaft 11 is rotatably connected to the outer wall of the tea screening box 1, so that the tea screening box 1 can move with the movable block 4, and movable cavities 5 adapted to the movable blocks 4 are opened inside the two support frames 2, and buffer springs 8 for support are connected between the movable blocks 4 and the inner walls at both ends of the movable cavities 5. When the tea screening box 1 vibrates to screen leaves, the movable block 4 will slide in the movable cavity 5 to produce a corresponding amplitude movement. At this time, the buffer spring 8 will be subjected to force to perform telescopic movement, which plays a good supporting role.

[0021] A connecting slide plate 10 is symmetrically fixed in the middle of the side wall of the movable block 4, and an inner slide groove 7 adapted to the connecting slide plate 10 is symmetrically opened on the inner wall of the movable cavity 5, which has a positioning function for the movable block 4 to prevent the movable block 4 from falling off during movement, and rubber pads 9 are glued and connected in the middle of both ends of the movable block 4. The rubber pads 9 are made of flexible material to avoid hard collisions.

[0022] Combination Figure 3 A screening chamber 12 is provided inside the tea screening box 1, and a cleaning chamber 14 is symmetrically provided at the bottom of the inner wall of the screening chamber 12. Broken leaves and impurities screened by the screening filter 13 will be discharged into the screening chamber 12. Discharge pipes 15 are fixedly connected to both sides of the bottom of the tea screening box 1, and a guide slope 17 is provided inside the cleaning chamber 14, which has a guide effect to promote the discharge of broken leaves through the discharge pipe 15.

[0023] The implementation principle of a fresh tea screening mechanism in the embodiment of the present application is as follows: when in use, fresh tea leaves are placed in the screening chamber 12, and then the vibration motor 16 is started. The vibration motor 16 uses the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block to obtain an exciting force, thereby driving the tea screening box 1 to vibrate, and the support base 3 supports its bottom to help the tea screening box 1 to produce a corresponding angle adaptation inside it. At the same time, as the tea screening box 1 moves, the connecting shaft 11 will push the movable block 4 to move a corresponding distance in the movable cavity 5 and reciprocate to squeeze the buffer spring 8 for buffering. At this time, the connecting slide plate 10 slides and positions in the inner slide groove 7 to prevent the movable block 4 from falling off in the support frame 2, thereby promoting the movement of fresh tea leaves on the surface of the screening filter 13 for screening, and the screened impurities and residual leaves will be diverted to the impurity removal chamber 14 and discharged through the discharge pipe 15.
