Description

Technical Field

[0001] The utility model relates to the field of tea processing, in particular to a pneumatic selection device for tea processing. Background Technique

[0002] In the process of tea processing, the pneumatic selection device, as an important screening tool, plays a significant role in improving the purity and quality of tea. With the continuous development of the tea industry and technological progress, the traditional screening methods have gradually been unable to meet the requirements of modern tea processing.

[0003] After retrieval, Chinese Patent Publication No.: CN218982335U discloses a pneumatic separator for tea processing. The utility model includes a support frame, a pneumatic selection channel is fixedly installed in the middle of the support frame, a plurality of baffle plates with different heights are fixedly installed at the top of the inner wall of the pneumatic selection channel, a plurality of grooves are opened at the bottom of the inner wall of the pneumatic selection channel, screening nets are arranged at the tops of the plurality of grooves, blanking devices are hermetically communicated with the bottoms of the plurality of grooves, and a plurality of discharging mechanisms are arranged on one side of the pneumatic selection channel. The beneficial effects of the utility model are as follows: By providing a vibration motor, it is convenient for the user to turn on the vibration motor, so that the vibration motor generates vibration and then vibrates the tea leaves blown onto the screening net by the fan blades, so that the residues in the tea leaves on the screening net enter the blanking device and are discharged outside the device through vibration, so that the residues in the tea leaves can be cleaned relatively cleanly, the impurity removal rate can be increased, and then the problem that a large amount of residues still exist in the tea leaves after screening is solved, and the quality of the tea is effectively improved.

[0004] In the above technology, although it is realized that by providing a vibration motor, it is convenient for the user to turn on the vibration motor, so that the vibration motor generates vibration and then vibrates the tea leaves blown onto the screening net by the fan blades, so that the residues in the tea leaves on the screening net enter the blanking device and are discharged outside the device through vibration. However, when a large amount of tea leaves enter the pneumatic selection channel at the same time, it may cause tea leaves of different weights and sizes to be blown simultaneously in a short time, resulting in uneven distribution of tea leaves in the pneumatic selection channel. In this case, light tea leaves may not be fully blown to a far position, and heavy tea leaves may also not be effectively separated due to the stacking effect, thus affecting the final screening effect. Therefore, a pneumatic selection device for tea processing is proposed to solve the above problems. Summary of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: a winnowing device for tea processing, including a winnowing machine body 1 for winnowing tea, which is a conventional structure and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. A blowing box 2 is fixedly connected to the right side of the winnowing machine body 1, and a feeding box 3 is fixedly connected to the top of the blowing box 2 for placing tea. A fan is arranged on the right inner wall of the blowing box 2 to generate air flow by rotation, providing wind power for the winnowing of tea. A driving motor 4 is fixedly connected to the rear side of the feeding box 3. The driving motor 4 is a reduction motor and serves as a power source. The rotation of its output shaft drives the rotation of a turntable 57. A transmission assembly is arranged on the inner wall of the feeding box 3. The transmission assembly includes a sliding plate 51. The sliding plate 51 and a fixed rod 52 move synchronously to achieve intermittent and regular control of feeding. The outer wall of the sliding plate 51 slides on the inner wall of the feeding box 3. A fixed rod 52 is fixedly connected to the rear side of the sliding plate 51 for connecting a moving plate 53 and the sliding plate 51 to drive the sliding plate 51 to move. A moving plate 53 that can reciprocate up and down is slidably connected to the inner wall of the feeding box 3 near the rear side of the fixed rod 52. A stabilizing column 58 is fixedly connected to the inner wall of the feeding box 3. The outer wall of the stabilizing column 58 slides in the inner wall of the moving plate 53 to improve the stability of the moving plate 53 when it moves.

[0033] Referring to Figure 3 - Figure 5, a guiding groove 54 is formed through the inner wall on the right side of the moving plate 53. The guiding groove 54 is inclined. The inclined design enables the fixing rod 52 to be converted into the horizontal movement of the moving plate 53 when sliding therein. The outer wall at the rear side of the fixing rod 52 slides on the inner wall of the guiding groove 54. A sliding groove 55 is formed through the middle part of the moving plate 53 in the horizontal direction to provide a sliding path for the sliding column 56. The inner wall of the sliding groove 55 is slidably connected with the sliding column 56. It slides in the sliding groove 55 of the moving plate 53, thereby driving the moving plate 53 to reciprocate up and down. A turntable 57 is fixedly connected to the rear side of the sliding column 56 and is driven to rotate by the driving motor 4. The rotational movement is converted into the reciprocating up and down movement of the moving plate 53 through the sliding column 56. The rear side of the turntable 57 is fixedly connected to the front end of the output shaft of the driving motor 4 and rotates with the output shaft of the driving motor 4, driving the sliding column 56 fixedly connected thereto to perform circular motion. There are two groups of the sliding plates 51 and the fixing rods 52. The two groups of the sliding plates 51 and the fixing rods 52 are symmetrically arranged with the center line of the feeding box 3 as the axis of symmetry, intercepting the tea leaves synergistically from both sides, improving the stability and consistency of feeding, and thus contributing to improving the working efficiency and the winnowing effect of the entire winnowing device.

[0034] Refer to Figure 3 and Figure 4 , an adjusting assembly is arranged on the outer wall of the sliding plate 51. The adjusting assembly includes an extrusion plate 61, which slides on the inner wall at the top end of the sliding plate 51 and cooperates with the adjusting column 64 to adjust the distance from the sliding plate 51, thus effectively avoiding the possible damage to the tea leaf quality caused by excessive extrusion and ensuring the integrity of the tea leaves. The bottom end of the extrusion plate 61 is slidably connected to the inner wall at the top end of the sliding plate 51. A sliding rod 63 is fixedly connected to the right side at the lower end of the extrusion plate 61 and is connected to the extrusion plate 61 and slides in the inner wall of the sliding plate 51 to ensure the stability of the sliding of the extrusion plate 61. The outer wall on the right side of the sliding rod 63 slides in the inner wall of the sliding plate 51. The sliding rod 63 and the sliding plate 51 are elastically connected by a compression spring 62 to connect the sliding rod 63 and the sliding plate 51 and provide an elastic restoring force for the sliding rod 63. The adjusting column 64 is threadedly connected to the inner wall on the left side of the extrusion plate 61. Rotating the adjusting column 64 can change the position of the extrusion plate 61. There are multiple groups of the adjusting columns 64, and the multiple groups of the adjusting columns 64 are symmetrically arranged with the center line of the extrusion plate 61 as the axis of symmetry. When it is necessary to adjust the distance between the extrusion plate 61 and the sliding plate 51, by rotating the adjusting column 64, since the adjusting column 64 is threadedly connected to the inner wall on the left side of the extrusion plate 61, rotating the adjusting column 64 will cause it to move axially, thereby pushing or pulling the extrusion plate 61 to slide relative to the sliding plate 51 and changing the distance between the two, so as to adapt to different specifications of tea leaves and improve the practicability of the equipment. A distributing rod 65 is fixedly connected to the inner wall at the bottom end of the feeding box 3 for distributing the falling tea leaves, thereby improving the working efficiency and the winnowing effect of the winnowing device.

[0035] Working principle: When in use, during the winnowing operation, the fan rotates on the inner wall on the right side of the blowing box 2 to generate an air flow, providing the wind force for the winnowing of the tea leaves.

[0036] First, put the tea leaves into the feeding box 3, and then start the driving motor 4. The output shaft thereof drives the turntable 57 to rotate. The sliding column 56 fixed on the turntable 57 will perform a circular motion accordingly. The sliding column 56 slides in the sliding groove 55 in the middle of the moving plate 53, thereby driving the moving plate 53 to reciprocate up and down. The guiding groove 54 on the right inner wall of the moving plate 53 is inclined. The fixed rod 52 slides in the guiding groove 54. When the moving plate 53 moves up and down, due to the inclined design of the guiding groove 54, the fixed rod 52 will drive the sliding plate 51 to slide horizontally and reciprocally on the inner wall of the feeding box 3. The two groups of sliding plates 51 and fixed rods 52 symmetrically arranged with the center line of the feeding box 3 as the axis work together to intercept the tea leaves from both sides, realizing the intermittent and regular control of feeding, improving the stability and consistency of feeding, and helping to improve the working efficiency and winnowing effect of the winnowing device.

[0037] By rotating multiple groups of symmetrically arranged adjusting columns 64, since the adjusting columns 64 are threadedly connected to the left inner wall of the pressing plate 61, rotating the adjusting columns 64 will cause them to move axially, changing the distance between the pressing plate 61 and the sliding plate 51 to adapt to different specifications of tea leaves, effectively avoiding damage to the tea leaf quality caused by excessive pressing, ensuring the integrity of the tea leaves, improving the usability of the equipment. At the same time, the sliding rod 63 slides on the inner wall of the sliding plate 51 to ensure the stability of the sliding of the pressing plate 61, and the compression spring 62 provides an elastic restoring force for the sliding rod 63.

[0038] After the tea leaves are adjusted and quantitatively pushed in the feeding box 3, they enter the blowing box 2 for winnowing.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
