Description

Technical Field

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

[0002] Withering involves spreading the leaves evenly under specific temperature and humidity conditions, which moderately promotes the activity of enzymes in the fresh leaves, causing moderate physical and chemical changes in the internal substances, releasing some moisture, and causing the stems and leaves to wilt, turn dark green, and lose their grassy smell. During the withering process, the fresh leaves undergo a series of changes: moisture decreases, and the leaves change from brittle and hard to soft, making them easier to roll into strips.

[0003] In existing tea withering methods, tea leaves are placed in drying trays, and multiple trays are placed on drying racks for withering. However, the tea leaves cannot be turned over during the withering process, resulting in inconsistent withering conditions between the tea leaves in contact with the drying trays and the upper surfaces. This necessitates increasing the withering time and reducing withering efficiency. To address these issues, we propose a tea withering device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tea withering device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tea withering device includes a fixed frame, a driving mechanism installed inside the fixed frame, a drying rack fixedly connected to the end of the fixed frame, a placement mechanism installed inside the drying rack, a separating sieve plate placed inside the placement mechanism, and a turning mechanism provided inside the drying rack.

[0007] Preferably, the driving mechanism includes a mounting plate, which is fixedly connected to the top of the fixed frame, and a drive motor is mounted on the top of the mounting plate. The output end of the drive motor is connected to a drive shaft, and multiple sets of drive gears are sleeved on the surface of the drive shaft. The function of the drive motor can be conveniently installed through the mounting plate fixedly connected to the top of the fixed frame.

[0008] Preferably, the placement mechanism includes a fixed rotating shaft. The fixed rotating shaft is installed inside the drying rack body through a bearing, and a fixed plate is fixedly connected above the fixed rotating shaft. The side of the fixed plate is fixedly connected to one end of the connecting column, and a limit ring is fixedly connected to the other end of the connecting column. The fixed rotating shaft can cause the fixed plate to drive the connecting column and the limit ring to rotate.

[0009] Preferably, a driven gear ring is sleeved on the outer side of the limiting ring, and the driving gear meshes with the surface of the driven gear ring, so that the driven gear ring can be driven to rotate.

[0010] Preferably, the size of the separating screen plate is adapted to the inner wall size of the limiting ring, and the interior of the separating screen plate is provided with dense through holes. By adapting the size of the separating screen plate to the inner wall size of the limiting ring, the separating screen plate can be easily placed inside the limiting ring.

[0011] Preferably, the turning mechanism includes a drive column, which is inserted into the inside of the drying rack. A fixed crossbar is fixedly connected to the end of the drive column. Multiple sets of turning rods are fixed at equal intervals below the fixed crossbar. The multiple sets of turning rods fixed at equal intervals below the fixed crossbar facilitate the turning of the tea leaves.

[0012] Preferably, the drying rack body has multiple sets of through holes evenly spaced inside, and guide posts are fixedly connected to the inner walls of the through holes. The guide posts are cylindrical, and the drive post has a circular hole adapted to the guide post inside. A return spring is sleeved on the surface of the guide post, and a return spring is welded between the drive post and the inner wall of the through hole. The cylindrical shape of the guide post can reduce wear between it and the drive post.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device allows the tea leaves to wither by placing the tea drying tray inside the limiting ring. The drive motor can drive the rotating shaft to rotate multiple sets of drive gears, which in turn drives the driven gear ring to rotate the limiting ring. At this time, the limiting ring will drive the fixed rotating shaft and the fixed plate to rotate between the fixed frame and the flipping mechanism, which facilitates the rotation of the tea drying tray and improves the withering efficiency.

[0015] 2. By pulling the drive column, the drive column can be moved along the surface of the guide column, which makes it easy for the fixed crossbar to drive the flipping rod away from the limit ring. This allows the tea drying tray to be placed inside the limit ring. Furthermore, through the elastic force of the return spring, the drive column can move the fixed crossbar and the flipping rod into the tea drying tray. This allows the flipping rod to turn the tea leaves when the tea drying tray rotates, thus reducing the withering time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4 A tea withering device includes a fixed frame 1, a driving mechanism 2 installed inside the fixed frame 1, and a drying rack 3 fixedly connected to the end of the fixed frame 1. The fixed frame 1 and the drying rack 3 can be used to conveniently limit the installation of the placement mechanism 4 as a whole. The drying rack 3 has the placement mechanism 4 installed inside, and a partition sieve plate 5 is placed inside the placement mechanism 4. The drying rack 3 is equipped with a flipping mechanism 6 inside.

[0028] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the driving mechanism 2 includes a mounting plate 21. The mounting plate 21 is fixedly connected to the top of the fixed frame 1, and a drive motor 22 is installed on the top of the mounting plate 21. The output end of the drive motor 22 is connected to a drive shaft 23, and multiple sets of drive gears 24 are sleeved on the surface of the drive shaft 23. The drive motor 22 can drive the drive shaft 23 to drive the multiple sets of drive gears 24 to rotate synchronously.

[0029] Furthermore, refer to Figure 2 and Figure 3It can be seen that the placement mechanism 4 includes a fixed rotating shaft 41. The fixed rotating shaft 41 is installed inside the drying rack 3 through a bearing, and a fixed plate 42 is fixedly connected above the fixed rotating shaft 41. The side of the fixed plate 42 is fixedly connected to one end of the connecting column 43, and the other end of the connecting column 43 is fixedly connected to a limit ring 44. Multiple sets of connecting columns 43 can conveniently provide auxiliary support for the separating screen plate 5, and at the same time improve the air circulation effect below the separating screen plate 5.

[0030] Furthermore, refer to Figure 2 and Figure 3 It can be seen that a driven gear ring 45 is sleeved on the outer side of the limiting ring 44, and the driving gear 24 meshes with the surface of the driven gear ring 45. Through the rotation of the driving gear 24, the driven gear ring 45 can drive the limiting ring 44 to rotate as a whole.

[0031] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the size of the separating screen plate 5 is compatible with the inner wall size of the limiting ring 44, and the interior of the separating screen plate 5 is provided with dense through holes, which facilitates air circulation.

[0032] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the flipping mechanism 6 includes a driving column 61. The driving column 61 is inserted inside the drying rack 3, and a fixed crossbar 62 is fixedly connected to the end of the driving column 61. Multiple sets of flipping rods 63 are fixed at equal distances below the fixed crossbar 62. The driving column 61 can drive the fixed crossbar 62 and the flipping rods 63 to be placed in the limiting ring 44.

[0033] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the drying rack body 3 has multiple sets of through holes at equal intervals inside, and guide posts 64 are fixedly connected to the inner wall of the through holes. The guide posts 64 are cylindrical. The inside of the driving post 61 has a round hole that matches the guide post 64. A return spring 65 is sleeved on the surface of the guide post 64. The return spring 65 is welded between the driving post 61 and the inner wall of the through hole. By moving the driving post 61 along the surface of the guide post 64, the return spring 65 can be compressed. And by the elastic force of the return spring 65 itself, the driving post 61 can be reset.

[0034] Working principle: When this utility model is in use, when the fixing frame 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4By pulling the drive column 61, the drive column 61 can move along the surface of the guide column 64, causing the return spring 65 to be compressed. At this time, the fixed crossbar 62 can drive the flipping rod 63 away from the limit ring 44, so that the tea drying tray can be placed into the limit ring 44. The connecting column 43 and the partition screen plate 5 provide auxiliary support for the tea drying tray. At this time, the fixed crossbar 62 and the flipping rod 63 are released, and the elastic force of the return spring 65 can push the drive column 61 to reset. At this time, the drive column 61 can drive the fixed crossbar 62 and the flipping rod 63 into the tea drying tray. Thus, when the drive motor 22 drives the drive shaft 23 and the drive gear 24 to rotate, the driven gear ring 45 drives the limit ring 44 to rotate, which facilitates the rotation of the tea drying tray. The flipping rod 63 can turn the tea leaves, improving the tea withering efficiency.
