The downward movement of the toothed plate pulls the telescopic column and the pressure-relieving spring, causing the pressure-relieving spring to generate tension. The toothed plate can also drive the impact component to move downward and impact the bearing plate, causing the support seat to move downward under pressure and compress the telescopic spring, causing the telescopic spring to generate elasticity. When the missing gear does not mesh with the toothed plate, both the pressure-relieving spring and the telescopic spring can release their tension and elasticity, pulling the impact component back to its initial position and pushing the support seat back. This causes the tea leaves in the bearing plate to vibrate and tumble back and forth, achieving the effect of assisting in the drying of the tea leaves. Attached Figure Description

[0046] Dryer 1;

[0047] Support base 2: Four support bases 2 are provided, and the four support bases 2 are located inside the dryer 1;

[0048] Support plate 3: There are four support plates 3, and the lower surfaces of the four support plates 3 are slidably connected to the inner wall of the support base 2;

[0049] Scraping mechanism 4: The scraping mechanism 4 is located inside the dryer 1, and includes:

[0050] Scraper 410: Several scraper 410s are provided, and all of the scraper 410s are provided on the upper surface of the bearing plate 3;

[0051] Connecting block 420: The outer surface of connecting block 420 is fixedly connected to the opposite side of scraper 410, and the lower surface of connecting block 420 is slidably connected to the inner wall of dryer 1;

[0052] Limiting groove 430: There are four limiting grooves 430. All four limiting grooves 430 are opened on the upper surface of the bearing plate 3 and the support base 2. The inner wall of the limiting groove 430 is slidably connected to the outer surface of the connecting block 420.

[0053] Transmission assembly 440: Transmission assembly 440 is located on the upper side of the bearing plate 3.

[0054] refer to Figure 3 As shown, the transmission assembly 440 includes:

[0055] Transmission block 441: The lower surface of transmission block 441 is fixedly connected to the upper surface of connecting block 420, and both the left and right sides of transmission block 441 are fixedly connected to the opposite end of the upper scraper 410.

[0056] Threaded rod 442: The outer surface of threaded rod 442 is rotatably connected to the inside of transmission block 441 by thread, and threaded rod 442 passes through the rear surface of dryer 1;

[0057] Motor 443: The output end of motor 443 is fixedly connected to the rear end face of threaded rod 442.

[0058] The above solution is adopted: the motor 443 is started, and the motor 443 drives the threaded rod 442 to rotate, so that the transmission block 441 moves along the outer surface of the threaded rod 442. The transmission block 441 can drive the connecting block 420 to move along the inner wall of the limiting groove 430. The connecting block 420 then drives the scraper 410 to move, so that the scraper 410 scrapes and stirs the tea leaves in the bearing plate 3, thereby increasing the drying efficiency of the tea leaves.

[0059] refer to Figure 3As shown, a fixing member 5 is provided on the front end face of the threaded rod 442. The interior of the fixing member 5 is rotatably connected to the front end face of the threaded rod 442 through a bearing. The upper surface of the fixing member 5 is fixedly connected to the inner wall of the dryer 1.

[0060] Using the above scheme: the fastener 5 mainly serves to support the threaded rod 442.

[0061] refer to Figure 3 As shown, the inner wall of the dryer 1 is provided with a spring-loaded assembly 6, and several spring-loaded assemblies 6 are provided. The several spring-loaded assemblies 6 include:

[0062] Sliding groove 601: The sliding groove 601 is formed on the inner wall of the dryer 1, and the outer surface of the support base 2 is slidably connected to the inner wall of the sliding groove 601;

[0064] The above scheme is adopted: during the stir-frying of tea leaves, the support seat 2 also moves downward along the inner wall of the sliding groove 601. The sliding groove 601 moves downward and squeezes the telescopic spring 602, causing the telescopic spring 602 to generate elastic force. Then, the telescopic spring 602 can release the elastic force and quickly push the support seat 2 back to the initial position. This cycle repeats to achieve the vibration effect and speed up the drying efficiency of the tea leaves.

[0065] refer to Figure 4 As shown, impact components 7 are provided on both the left and right sides of the threaded rod 442. Several impact components 7 are provided, and the several impact components 7 include:

[0066] Support plate 701: The opposite side of support plate 701 is fixedly connected to the inner wall of dryer 1;

[0067] Telescopic column 702: The upper end face of the telescopic column 702 is fixedly connected to the lower surface of the support plate 701;

[0070] Missing gear 705: The outer surface of missing gear 705 is in a meshing relationship with the opposite side of tooth plate 704;

[0071] Impact component 706: The upper surface of the impact component 706 is fixedly connected to the lower surface of the toothed plate 704.

[0072] Using the above scheme: In order to move the support 2 downward, the missing gear 705 rotates and meshes with the toothed plate 704, causing the toothed plate 704 to move downward. The downward movement of the toothed plate 704 can pull the telescopic column 702 and the pressure relief spring 703, causing the pressure relief spring 703 to generate tension. The toothed plate 704 can drive the impact member 706 to move downward and impact the bearing plate 3, causing the support 2 to move downward under pressure. When the missing gear 705 does not mesh with the toothed plate 704, the pressure relief spring 703 can release the tension and pull the impact member 706 back to the initial position.

[0073] refer to Figure 2 and Figure 4 As shown, a drive assembly 8 is provided on the rear surface of the missing gear 705. The drive assembly 8 includes:

[0074] Connecting rod 801: Several connecting rods 801 are provided. The front end face of several connecting rods 801 is fixedly connected to the rear surface of the missing gear 705. The connecting rods 801 pass through the rear surface of the dryer 1.

[0075] Toothed pulley 802: Several toothed pulleys 802 are provided, and the toothed pulleys 802 are connected to each other by toothed belt drive. The rear end face of the connecting rod 801 is fixedly connected to the front surface of the toothed pulley 802, the outer surface of the connecting rod 801 is fixedly connected to the inside of the toothed pulley 802, and the inner wall of the middle toothed pulley 802 is fixedly connected to the outer surface of the threaded rod 442.

[0076] Auxiliary gear 803: The front surface of auxiliary gear 803 is fixedly connected to the rear end face of the upper left connecting rod 801;

[0077] Main gear 804: The outer surface of the main gear 804 and the outer surface of the auxiliary gear 803 are meshed with each other. The front surface of the main gear 804 is fixedly connected to the rear end face of the threaded rod 442, and the inner surface of the main gear 804 is fixedly connected to the outer surface of the output end of the motor 443.

[0078] The above scheme is adopted as follows: In order to make the missing gear 705 rotate, the main gear 804 is driven to rotate by the motor 443. The rotation of the main gear 804 meshes with the auxiliary gear 803. The auxiliary gear 803 drives the left toothed pulley 802 to rotate through the left connecting rod 801. The left toothed pulley 802 can drive the remaining left connecting rod 801 to rotate. The connecting rod 801 then drives the missing gear 705 to rotate. The right toothed pulley 802 is driven by the threaded rod 442.

[0079] refer to Figure 2 As shown, a fixing sleeve 9 is fixedly connected to the outer surface of the motor 443, and the front surface of the fixing sleeve 9 is fixedly connected to the rear surface of the dryer 1.

[0080] Using the above scheme: the fixing sleeve 9 mainly serves to fix and support the motor 443.

[0081] The working principle of this utility model:

[0082] In use, tea leaves are placed inside the bearing tray 3. The dryer 1 and motor 443 are started. Motor 443 drives the threaded rod 442 to rotate, causing the transmission block 441 to move along the outer surface of the threaded rod 442. The transmission block 441 drives the connecting block 420 to move along the inner wall of the limiting groove 430. The connecting block 420 then drives the scraper 410 to move, causing the scraper 410 to scrape and stir-fry the tea leaves in the bearing tray 3. Simultaneously, the threaded rod 442 drives the right-side toothed pulley 802 to rotate. Motor 443 drives the main gear 804 to rotate. The main gear 804 meshes with the auxiliary gear 803. The auxiliary gear 803 drives the left-side toothed pulley 802 to rotate via the left-side connecting rod 801. Finally, the connecting rods 801 on both sides rotate together, causing the missing gear 705 to rotate. The toothed gear 705 rotates and meshes with the toothed plate 704, causing the toothed plate 704 to move downwards. The downward movement of the toothed plate 704 pulls the telescopic column 702 and the pressure-relieving spring 703, causing the pressure-relieving spring 703 to generate tension. The toothed plate 704 can drive the impact member 706 to move downwards and impact the bearing plate 3, causing the support seat 2 to move downwards under pressure and squeeze the telescopic spring 602, causing the telescopic spring 602 to generate elasticity. When the toothed gear 705 does not mesh with the toothed plate 704, both the pressure-relieving spring 703 and the telescopic spring 602 can release tension and elasticity, pulling the impact member 706 back to its initial position and pushing the support seat 2 to move back, causing the tea leaves in the bearing plate 3 to be vibrated and turned back and forth, accelerating the drying efficiency of the tea leaves. After drying is completed, the dryer 1 and motor 443 can be turned off, and the dryer 1 can be turned on again. The bearing plate 3 can be pulled out to remove the tea leaves.

[0083] In summary, this tea leaf dryer, through its dryer 1, support base 2, bearing plate 3, scraping mechanism 4, fixing component 5, rebound component 6, impact component 7, drive component 8, and fixing sleeve 9, solves the problem that tea leaves are often stacked inside the dryer, which leads to different drying efficiencies between the tea leaves pressed inside and those on the outside, resulting in the tea leaves inside not being completely dried and greatly affecting the overall quality of the tea.
