Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a device for removing residual leaves. Background Technology

[0002] In the tea processing industry, tea leaves are often mixed with solid impurities (such as soil, sand, etc.) and residual leaves after harvesting. The presence of these impurities and residual leaves seriously affects the quality and taste of the tea, and also fails to meet the quality standards for tea products. Traditional tea screening methods are often unable to efficiently remove solid impurities and residual leaves simultaneously, resulting in low tea processing efficiency and inconsistent product quality.

[0003] Existing tea sorting equipment is not effective at removing solid impurities. For example, simple sorting devices cannot accurately separate solid impurities such as soil and sand from tea leaves, causing them to interfere with subsequent processing, increasing processing costs and difficulty. Moreover, this method cannot effectively separate residual leaves, and simple air separation equipment cannot effectively separate tea leaves and residual leaves based on their characteristics, resulting in a large amount of residual leaves remaining in the tea leaves, affecting the purity and quality of the tea.

[0004] To address the aforementioned issues and improve the efficiency and quality of tea processing, developing a device capable of simultaneously and efficiently removing solid impurities and residual leaves is of significant practical importance. Utility Model Content

[0005] In view of this, the present invention provides a residual leaf removal device, which can not only effectively separate dirt and other impurities in tea leaves through a solid screening component, but also effectively separate residual leaves through a residual leaf screening component, thereby improving the purity and quality of the tea leaves.

[0006] To solve the above-mentioned technical problems, this utility model provides a leaf residue removal device, including a device base, on which a solid screening component and a leaf residue screening component disposed on one side of the solid screening component are respectively included. The leaf residue screening component is used to receive tea leaves after solid screening. The solid screening component includes a material trough mounted on the device base by a support column, and a vibrating screen is connected and installed inside the material trough. A first discharge port is connected and disposed below the vibrating screen. That is, the vibrating screen in the solid screening component is used to screen and separate the soil from the tea leaves, and the soil is discharged through the first discharge port at the bottom of the vibrating screen.

[0007] The residual leaf screening assembly includes an air duct mounted on the base of the device, with a vibrating plate connected to the duct for conveying tea leaves. The vibrating plate has air holes for airflow. Below the vibrating plate is a guide air duct, with a blower connected to its bottom. In other words, by utilizing the airflow generated by the blower, the residual leaves in the tea leaves are screened through the guide air duct and the air holes on the vibrating plate. The airflow blows up and separates lighter impurities such as residual leaves, while the tea leaves remain on the vibrating plate for continued conveying, thus achieving the separation of tea leaves and residual leaves and improving the purity of the tea.

[0008] Extending platforms are staggered on both sides of the duct, and each platform is symmetrically equipped with damping springs. The vibrating plate is mounted on the duct via these damping springs. In other words, the damping springs reduce the vibration of the vibrating plate during operation, thus mitigating the impact on the duct and the overall operating environment of the equipment, while also reducing the noise generated by the equipment during operation.

[0009] The vibrating screen is symmetrically equipped with compression springs at its bottom, and the screen is positioned within the material trough via these springs. In other words, the compression springs enhance the vibration effect of the screen, allowing it to buffer and regulate vibrations during operation, preventing damage from excessive vibration, and improving screening accuracy and efficiency.

[0010] Both the vibrating plate and the vibrating screen are fixedly equipped with vibrating motors at their bottom. The vibrating motors provide power to the vibrating plate and screen, causing them to vibrate. For the vibrating screen, vibration accelerates the material screening speed and improves screening efficiency; for the vibrating plate, vibration promotes the transport of tea leaves and, in conjunction with airflow, better separates residual leaves, ensuring the normal operation and high efficiency of the equipment.

[0011] The top outlet of the duct serves as the second discharge port. That is, debris such as fallen leaves blown up by the airflow is discharged through the discharge port located at the top of the duct, which facilitates the centralized processing of the separated impurities, ensures the cleanliness and normal operation of the equipment, and simultaneously removes fallen leaves.

[0012] The outlet of the vibrating plate serves as the third discharge port. That is, the qualified tea leaves remaining after the residual leaves have been screened out are discharged through this outlet, which facilitates the collection and subsequent processing of the processed tea leaves.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. First, the material is preliminarily screened by the vibrating screen of the solid screening component to remove solid impurities. Then, the screened tea leaves are conveyed to the residual leaf screening component for further residual leaf screening, which can effectively separate solid impurities and residual leaves in the tea leaves, significantly improve the purity of the tea leaves, and ensure the quality of the tea leaves.

[0015] 2. An exhaust fan generates airflow through an air duct. The airflow passes through the pores on the vibrating plate and acts on the tea leaves. Because the residual leaves are relatively light, they are separated from the tea leaves by the airflow and discharged through the outlet at the top of the duct (second discharge port). This method of separating residual leaves by airflow is more efficient and environmentally friendly than traditional screening methods, avoiding the use of chemical agents or other methods that may contaminate the tea leaves.

[0016] 3. Shock-absorbing springs are symmetrically installed on the expansion platforms on both sides of the air duct, and the vibrating plate is set on the air duct through the shock-absorbing springs; compression springs are also symmetrically installed at the bottom of the vibrating screen, and the vibrating screen is set in the material trough through the compression springs. This can effectively reduce the vibration and noise generated during equipment operation, which can not only extend the service life of the equipment, but also provide a relatively quiet working environment for operators, while ensuring the stability of equipment operation and improving the screening effect.

[0017] 4. The vibrating motor can generate vibration, which makes the tea leaves on the vibrating screen and vibrating plate move continuously, preventing the tea leaves from piling up and allowing the tea leaves to come into fuller contact with the screen or airflow, thereby enhancing the screening effect, improving the separation efficiency of residual leaves and impurities, and further improving the quality of tea leaves and screening efficiency.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] like Figure 1-5 As shown: This embodiment provides a leaf residue removal device, including a device base 100. The device base 100 includes a solid screening component 200 and a leaf residue screening component 300 disposed on one side of the solid screening component 200. The leaf residue screening component 300 is used to receive tea leaves after solid screening. The solid screening component 200 includes a material trough 202 disposed on the device base 100 by a support column 201. A vibrating screen 203 is connected and installed inside the material trough 202. A first discharge port 204 is connected and disposed below the vibrating screen 203. When tea leaves are placed on the vibrating screen 203 of the material trough 202, the vibrating screen 203 operates. Solid impurities in the tea leaves cannot pass through the vibrating screen 203 and fall through the screen holes on the vibrating screen 203 into the first discharge port 204 for discharge. Meanwhile, the tea leaves pass through the vibrating screen 203 and fall from the tail of the vibrating screen 203 into the residual leaf screening component 300, thereby achieving the screening of solid impurities in the tea leaves. The tea leaves after solid screening are then transported to the residual leaf screening component 300 for further processing, initially separating the tea leaves and solid impurities and improving the purity of the tea leaves.

[0026] The residual leaf screening assembly 300 includes an air duct 301 mounted on the device base 100. A vibrating plate 302 for conveying tea leaves is connected and installed on the air duct 301. The vibrating plate 302 has air holes 303 for air circulation. A guide air duct 304 is installed below the vibrating plate 302, and a blower 305 is connected to the bottom of the guide air duct 304. When the tea leaves are conveyed through the vibrating plate 302, the blower 305 operates, causing the airflow to flow upward through the air holes 303 via the guide air duct 304. Since the residual leaves are lighter, they are carried away by the airflow, while the tea leaves, which are relatively heavier, remain on the vibrating plate 302, thus achieving the separation of residual leaves and tea leaves.

[0027] Extending platforms are staggered on both sides of the duct 301, and each extending platform is symmetrically equipped with a shock-absorbing spring 306. The vibrating plate 302 is mounted on the duct 301 via the shock-absorbing spring 306. When the vibration motor 400 on the vibrating plate 302 operates to vibrate the vibrating plate 302, the shock-absorbing spring 306 can absorb and buffer the vibration energy, reducing the vibration transmitted to the duct 301, thereby ensuring the stability of the duct 301 and thus ensuring the stable operation of the entire equipment.

[0028] Compression springs 205 are symmetrically installed at the bottom of the vibrating screen 203, and the vibrating screen 203 is positioned within the material trough 202 via the compression springs 205. When the vibrating motor 400 on the vibrating screen 203 operates, the compression springs 205 extend and retract with the vibration of the vibrating screen 203, playing a role in buffering and enhancing the vibration. On the one hand, this makes the vibration of the vibrating screen 203 more uniform and stable; on the other hand, it increases the vibration amplitude of the vibrating screen 203, allowing the tea leaves to tumble and move better on the vibrating screen 203, thereby improving the screening efficiency and effect of solid impurities.

[0029] Both the vibrating plate 302 and the vibrating screen 203 have a vibrating motor 400 fixedly installed at their bottom. When the vibrating motor 400 is working, it will generate vibration, which is transmitted to the vibrating screen 203 and the vibrating plate 302. This allows the vibrating screen 203 to screen solid impurities in the tea leaves, and the vibrating plate 302 to transport the tea leaves and, in conjunction with the airflow, screen residual leaves.

[0030] The top outlet of the duct 301 serves as the second discharge port 307. When the induced draft fan 305 causes the airflow to carry away the residual leaves, the residual leaves will rise with the airflow through the duct 301 and eventually be discharged from the second discharge port 307 at the top, which facilitates the unified collection and treatment of the residual leaves.

[0031] The outlet of the vibrating plate 302 serves as the third discharge port 308. After solid screening and residual leaf screening, qualified tea leaves will move towards the outlet under the vibration of the vibrating plate 302 and finally be discharged from the third discharge port 308, thus completing the entire process of removing residual tea leaves and facilitating the subsequent collection and utilization of qualified tea leaves.

[0032] The method of using this utility model is as follows: When removing residual leaves from tea leaves, the tea leaves should first be poured into the material trough 202. The vibrating screen 203 and the vibrating motor 400 at the bottom of the vibrating plate 302 are then started to convey the tea leaves. As the tea leaves move on the vibrating screen 203, dirt and other impurities are separated and discharged through the first discharge port 204. The tea leaves fall into the residual leaf screening component 300 through the conveying of the vibrating screen 203. The induced draft fan 305 operates while the tea leaves are conveyed by the vibrating plate 302. The airflow is directed upwards through the air vents 303 via the air duct 304. Since the residual leaves are lighter, they are carried away by the airflow, while the tea leaves, which are relatively heavier, remain on the vibrating plate 302 and move to one side. After the blower 305 carries away the residual leaves with the airflow, the residual leaves will rise through the air duct 301 with the airflow and finally be discharged from the second discharge port 307 at the top. After solid screening and residual leaf screening, the qualified tea leaves will move towards the outlet under the vibration of the vibrating plate 302 and finally be discharged from the third discharge port 308.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
