Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a high-efficiency tea collection and screening device. Background Technology

[0002] Tea leaves refer to the leaves of the tea plant, an evergreen shrub used for brewing tea. Tea leaves contain catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all of which are beneficial to health. During tea production, processing is required. This processing involves screening the harvested tea leaves, removing smaller leaves to improve their quality.

[0003] Chinese utility model patent No. 202420876685.5, entitled "A Tea Collection and Screening Device," describes a method where tea leaves are placed in a screening box within a housing. A motor 34 on the bottom surface of the side plate drives a cam to rotate, which in turn moves a push rod on one side of the screening box, allowing the screening box to move within the housing. As the screening box moves, it compresses a return spring on a limiting rod. The combination of the limiting rod and the return spring allows the screening box to move back and forth within the housing. The tea leaves are then screened through screening holes on the screening box. However, this method, by placing tea leaves in the screening box and moving it left and right, separates smaller tea leaves through screening holes at the bottom of the box. However, because tea leaves are sheet-like and often stacked together, smaller tea leaves at the top are often blocked by tea leaves at the bottom during the left-right movement, making them difficult to screen. This results in poor screening efficiency. If only a thin layer of tea leaves is placed at the bottom of the screening box for screening, the efficiency of tea screening is further reduced. Utility Model Content

[0004] In order to overcome the problems existing in the background art, this utility model provides a high-efficiency tea collection and screening device to solve the technical problems of poor screening effect and low tea screening efficiency of existing tea screening devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0011] Preferably, a collection box 9 for collecting the screened tea leaves is provided below the discharge port 8.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a drum screen to screen tea leaves. When the drum screen rotates, the tea leaves are turned over, and smaller tea leaves leak out through the screening holes. The screened tea leaves are discharged from the end of the drum screen, thus achieving tea leaf screening. This drum screen avoids the situation where tea leaves on the upper layer cannot be screened, as it turns over the entire tea pile, allowing all tea leaves in the drum screen to be screened. At the same time, when the drum screen rotates, the stirring rod agitates the tea leaves, making it easier for smaller tea leaves to be screened out, improving the efficiency and quality of tea leaf screening. Furthermore, the stirring rod, which is set on the inner wall of the drum screen, rotates along with it, only contacting the tea leaves and not contacting or colliding with other parts of the device, thus avoiding damage to the tea leaves when the stirring rod agitates them.

[0018] like Figure 1-4As shown, this utility model provides a high-efficiency tea collection and screening device, including a housing 1, a feeding mechanism 2, and a screening mechanism 3. The screening mechanism 3 is installed in the housing 1, and the feeding mechanism 2 is also installed in the housing 1, with its lower end connected to the feed inlet of the screening mechanism 3 and its upper end positioned on the top of the housing 1. The screening mechanism 3 includes a fixed cylinder 31, a drum screen 32, a stirring rod 33, and a motor 34. The fixed cylinder 31 is fixedly installed inside the housing 1. The drum screen 32 has screening holes 321 evenly arranged on its side wall and is rotatably installed in the fixed cylinder 31. The drum screen 32 is connected to annular slide rails at both ends. The agitator 35 is rotatably installed in the annular groove 36 provided on the inner wall of the fixed cylinder 31; the fixed cylinder 31 and the drum screen 32 are inclinedly arranged in the machine box 1, the agitator 33 is evenly arranged on the inner wall of the drum screen 32, the end of the drum screen 32 is provided with a funnel-shaped inlet that connects with the discharge end of the feeding mechanism 2, the side wall of the inlet is provided with an annular groove for belt connection, the annular groove is connected to the motor 34 installed at the bottom of the machine box 1 through the belt, driving the drum screen 32 to rotate in the fixed cylinder 31, and the bottom of the fixed cylinder 31 is provided with a discharge window 311 to facilitate the leakage of small tea leaves. When screening tea leaves, the tea leaves are poured into the feeding mechanism 2 in sequence. The tea leaves then enter the screening mechanism 3 along with the feeding mechanism 2. The motor 34 drives the drum screen 32 to rotate under the support of the fixed cylinder 31, thereby turning over the tea leaves in the drum screen 32. Smaller tea leaves are allowed to pass through the screening holes 321 on the side wall of the drum screen 32 and be discharged from the discharge port at the bottom of the fixed cylinder 31. The screened tea leaves move with the inclined drum screen 32 and are discharged from the bottom of the drum screen 32, thus achieving the screening of tea leaves. The stirring rod 33 stirs the turning tea leaves, so that smaller tea leaves can be screened out as much as possible. The drum screen 32 rotates under the support of the annular slide rail 35 and the annular slide groove 36. Lubricating oil can be applied to the annular slide rail 35 to facilitate the rotation of the drum screen 32. This utility model, through the setting of the drum screen The drum screen 32 is used to screen tea leaves. When the drum screen 32 rotates, the tea leaves are turned over. Smaller tea leaves leak out through the screening holes 321, and the screened tea leaves are discharged from the end of the drum screen 32, thus achieving the screening of tea leaves. The drum screen 32 avoids the situation where the upper layer of tea leaves cannot be screened. It turns the tea leaves as a whole, so that all the tea leaves in the drum screen 32 can be screened. At the same time, when the drum screen 32 rotates, the stirring rod 33 stirs the tea leaves, which makes it easier for smaller tea leaves to be screened out, improving the efficiency and quality of tea leaf screening. The stirring rod 33, which is set on the inner wall of the drum screen 32, rotates with it and only contacts the tea leaves, without contacting or colliding with other parts of the device, thus avoiding damage to the tea leaves when the stirring rod 33 stirs the tea leaves.

[0020] The fixed cylinder 31 has multiple air blowing pipes 4 evenly arranged axially along its sidewall, blowing air towards the sidewall of the drum screen 32. These air blowing pipes 4 are connected to the sidewall of an air supply pipe 5 located on the outer wall of the housing 1. The air supply pipe 5 is connected to a fan 6 installed on the sidewall of the housing 1. When tea leaves are screened in the drum screen 32, some tea leaves may become stuck in the screening holes 321, blocking smaller tea leaves from being screened out. The fan 6 generates airflow, which is blown from the air blowing pipes 4 and hangs on the sidewall of the drum screen 32, thus blowing the tea leaves stuck in the screening holes 321 into the drum screen 32, preventing them from affecting the screening process.

[0021] The bottom of the casing 1 is provided with a discharge hopper 7 located below the drum screen 32 to facilitate the discharge of smaller tea leaves.

[0022] The end of the casing 1 is provided with an outlet 8 that connects with the discharge end of the drum screen 32 to facilitate the discharge of the screened tea leaves.

[0023] Below the outlet 8 is a collection box 9 for collecting the screened tea leaves.

[0024] Work process:

[0025] When screening tea leaves, the tea leaves are poured into the feeding mechanism 2 in sequence. The tea leaves enter the screening mechanism 3 along with the feeding mechanism 2. The motor 34 drives the drum screen 32 to rotate under the support of the fixed cylinder 31, thereby turning over the tea leaves in the drum screen 32. Smaller tea leaves are allowed to leak out from the screening holes 321 on the side wall of the drum screen 32 and be discharged from the discharge port at the bottom of the fixed cylinder 31. The screened tea leaves move with the inclined drum screen 32 and are discharged from the lower end of the drum screen 32, thus achieving the screening of tea leaves. The stirring rod 33 stirs the turning tea leaves so that smaller tea leaves can be screened out as much as possible. The fan 6 generates air force, and the air blows out from the blower pipe 4 and hangs on the side wall of the drum screen 32, thereby blowing the tea leaves stuck in the screening holes 321 into the drum screen 32, preventing the tea leaves stuck in the screening holes 321 from affecting the screening of tea leaves.
