Description

Technical Field

[0001] This utility model relates to the field of tea storage and feeding technology, specifically an automatic feeding device for tea production. Background Technology

[0002] Freshly picked tea leaves contain high levels of moisture and other impurities, making them prone to fermentation and spoilage under unsuitable conditions, affecting their taste and quality. Using a tea drying machine effectively removes excess moisture and impurities, ensuring tea quality. After drying in the drying chamber, the tea leaves need to be discharged. Currently, a discharge pipe is installed at the bottom of the drying chamber, but its diameter cannot cover the entire interior of the chamber, resulting in incomplete discharge and potential blockages during the discharge process. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic feeding device for tea production, thereby solving the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: an automatic feeding device for tea processing, including a tea drying box, a feeding plate provided inside the tea drying box, the feeding plate being a thin metal plate, the high end of the feeding plate being connected to the inner side wall of the tea drying box, the low end of the feeding plate being connected to the inner bottom wall of the tea drying box, a vibration mechanism being provided below the feeding plate, the vibration mechanism being used to cause the feeding plate to vibrate, a feeding port being provided at the bottom of the tea drying box, the feeding port being truncated cone-shaped, the large-diameter end of the feeding port being formed between the low end of the feeding plate and the side wall of the tea drying box, and the small-diameter end of the feeding port being connected to a feeding pipe.

[0005] Furthermore, the vibration mechanism includes a motor and a cam. The motor is mounted on the inner bottom wall of the tea drying box, and the output shaft of the motor is connected to the cam. The cam is used to collide with the feeding plate to generate vibration.

[0006] Furthermore, the tea drying box is equipped with a pusher plate, which contacts the top surface of the feed plate and has the freedom to move along the inclined surface of the feed plate.

[0007] Furthermore, a pusher cylinder is installed at an angle on the outer wall of the tea drying box, and the telescopic shaft of the pusher cylinder passes through the tea drying box and connects to the pusher plate.

[0008] Furthermore, a sealing plate is provided at the top of the discharge port, and the sealing plate has the freedom to move in the horizontal direction.

[0009] Furthermore, a horizontal cylinder is installed at the bottom of the tea drying box, and one end of the sealing plate extends through the telescopic shaft of the tea drying box that connects to the horizontal cylinder.

[0010] Furthermore, the top of the tea drying box is fixed with multiple support legs, and the top of the tea drying box is equipped with a feed hopper.

[0011] Furthermore, the top of the feed hopper is threadedly connected to a cover plate.

[0012] The beneficial effects of this utility model are:

[0013] The tea leaves are guided into the feeding port by the feeding plate and then discharged through the feeding pipe, making the discharge more thorough. Secondly, the feeding plate is vibrated by the vibration mechanism, which accelerates the movement of the tea leaves, making the discharge efficiency higher and avoiding the problem of discharge blockage.

[0017] Example 1

[0018] like Figure 1 and Figure 2As shown, an automatic feeding device for tea processing includes a tea drying box 1. A feeding plate 2, made of thin metal sheet, is installed inside the tea drying box 1. The upper end of the feeding plate 2 is connected to the inner side wall of the tea drying box 1, and the lower end is connected to the inner bottom wall of the tea drying box 1. A vibration mechanism is installed below the feeding plate 2 to cause it to vibrate. A feeding port 3, shaped like a frustum, is opened at the bottom of the tea drying box 1. The larger diameter end of the feeding port 3 is formed between the lower end of the feeding plate 2 and the side wall of the tea drying box 1, and the smaller diameter end of the feeding port 3 is connected to a feeding pipe 4. Multiple support legs 11 are fixed to the top of the tea drying box 1, and a feeding hopper 12 is installed at the top of the tea drying box 1 to feed tea leaves. Inside the drying chamber 1, an electric heating element is installed between the inner and outer walls of the tea drying chamber 1. The electric heating element dries the tea leaves inside the tea drying chamber 1. The tea drying chamber 1 is equipped with a stirring mechanism, which includes a rotating shaft and rotating blades mounted on the rotating shaft. The rotating shaft is driven by a stirring motor installed on the top of the tea drying chamber 1. This is existing technology and will not be described in detail. After the tea leaves are dried, they are discharged from the tea drying chamber 1 through the discharge pipe 4. The tea leaves are guided by the discharge plate 2 to enter the discharge port 3, and then discharged through the discharge pipe 4, making the discharge of tea leaves more thorough. In addition, the vibration mechanism causes the discharge plate to vibrate, accelerating the movement of the tea leaves, making the discharge efficiency higher, and also avoiding the problem of discharge blockage.

[0019] Furthermore, the top of the feed hopper 12 is threadedly connected to a cover plate 13. During the drying operation, the opening of the feed hopper 12 is blocked by the cover plate 13 to prevent heat loss from the tea drying box 1. Several exhaust holes are provided on the cover plate 13 to discharge water vapor from the tea drying box 1.

[0020] Example 2

[0021] Based on Embodiment 1, the vibration mechanism includes a motor 5 and a cam 6. The motor 5 is installed on the inner bottom wall of the tea drying box 1. The output shaft of the motor 5 is connected to the cam 6. The cam 6 is used to collide with the feeding plate 2 to generate vibration. The motor 5 drives the cam 6 to rotate. The cam 6 collides with the feeding plate 2, causing the feeding plate 2 to undergo frequent recoverable deformation, thereby generating vibration in the feeding plate 2, accelerating the discharge efficiency of tea and avoiding blockage.

[0022] Example 3

[0023] Based on Example 2, such as Figure 1As shown, a pusher plate 7 is provided inside the tea drying box 1. The pusher plate 7 contacts the top surface of the feed plate 2. The pusher plate 7 has the freedom to move along the inclined surface of the feed plate 2. A pusher cylinder 8 is installed at an angle on the outer wall of the tea drying box 1. The telescopic shaft of the pusher cylinder 8 passes through the tea drying box 1 and connects to the pusher plate 7. The pusher cylinder 8 drives the pusher plate 7 to move on the upper inclined surface of the feed plate 2. The pusher plate 7 scrapes off the tea leaves adhering to the feed plate 2, reducing the amount of tea waste.

[0024] Example 4

[0025] Based on Example 3, such as Figure 1 As shown, a sealing plate 9 is installed at the top of the feeding port 3. The sealing plate 9 has the freedom to move in the horizontal direction. A horizontal cylinder 10 is installed at the bottom of the tea drying box 1. One end of the sealing plate 9 passes through the telescopic shaft of the horizontal cylinder 10 connected to the tea drying box 1. The sealing plate 9 is moved by the telescopic movement of the horizontal cylinder 10. When the tea is drying, the sealing plate 9 moves to the top of the feeding port 3 and seals the feeding port 3, so that the tea leaves remain in the tea drying box 1 for drying. After drying is completed, the sealing plate 9 moves to one side of the feeding port 3, so that the feeding port 3 is opened and the tea leaves can enter the feeding pipe 4 through the feeding port 3 and be discharged through the feeding pipe 4.
