The utility model can achieve preliminary screening of tea leaves by arranging a vibrating screening component 400 at the lower part of the tea separation box 1, and guide the screened tea leaves by the guide plates 200 inclinedly arranged on the left and right sides of the tea separation box 1, thereby solving the problem that the feed hopper 300 of the existing tea screening machine usually only has the function of conveying tea leaves and does not have the function of preliminary screening of tea leaves. This leads to a large workload in the subsequent screening process for the tea leaves falling through the feed hopper 300, which can easily cause large and small tea leaves to be mixed together and blocked or fall together along the screen plate into the classification box, resulting in the problem that the screened tea leaves are still mixed with tea leaves of different sizes, requiring manual secondary screening operations. There is no need for manual secondary sorting, the operation is simpler, and the screening efficiency of the tea leaves is greatly improved.
[0019] According to one embodiment of the present invention, Figure 1 、 Figure 2 and Figure 3As shown, a collecting bucket is placed on the outside of each guide plate 200, and a motor is provided on the outside of the output shaft of the conveying auger. The housing of the motor is fixed on the outer wall of the separation box, and a storage box is provided in the cavity between the output shaft of the motor and the arc-shaped baffle 401. The lower part of the storage box is provided with a discharge port with a sealing plug, which is a rubber plug. The rubber sealing plug can effectively seal the discharge port of the storage box. The telescopic sleeve 403 includes a fixed end hingedly arranged in the arc-shaped through groove 402, and a spring is provided inside the fixed end. The other end of the spring is provided with a telescopic end. The utility model can drive the conveying auger to rotate by the rotation of the output shaft of the motor. The rotating conveying auger can guide and convey the tea leaves falling through the feed hopper 300, and the falling tea leaves and the slight vibration of the conveying auger itself can drive the elasticity of the telescopic sleeve 403. The spring contracts, and then pushes the telescopic end with the arc-shaped sliding sleeve 404 and the arc-shaped screen drum 405 to reciprocate along the circumference of the arc-shaped baffle 401, thereby producing an effect similar to a vibrating screen, realizing the vibration screening of the tea leaves. The tea leaves with a smaller aperture than the screen holes of the arc-shaped screen drum 405 fall through the guide plate 200 and slide out to be collected by the collecting device pre-placed at the lower part of the guide plate 200. With the rotation of the conveying auger, the tea leaves with a larger aperture than the drying mesh holes of the arc-shaped screen drum 405 will be conveyed to the storage box under the guidance and conveying action of the conveying auger. After screening for a certain period of time, the screening operation is stopped and the sealing plug is opened.

Through the cooperation of the baffle and the limit plate, the rotation angle of the arc-shaped screen drum 405 can be limited, and the operation is more convenient.
[0021] The use method of this utility model:
[0022] First of all, it should be made clear that the screening machine involved in the present invention is mainly used for screening tea leaves. The present invention takes the screening of tea leaves as an example to explain its method of use in detail. When the tea leaves need to be screened, the output shaft of the motor is started to rotate, and the tea leaves to be screened are poured into the top of the feed hopper 300 at the same time. The rotation of the output shaft of the motor drives the conveying auger to rotate. The rotating conveying auger can guide and transport the tea leaves falling through the feed hopper 300. The falling tea leaves and the slight vibration of the conveying auger itself can drive the auger to move. The spring of the retracting sleeve rod 403 contracts, and then pushes the telescopic end with the arc-shaped sliding sleeve 404 and the arc-shaped screen drum 405 to reciprocate along the circumference of the arc-shaped baffle 401, thereby producing an effect similar to a vibrating screen, realizing the vibration screening of the tea leaves. The tea leaves with a diameter smaller than the sieve holes of the arc-shaped screen drum 405 fall through the guide plate 200 and slide out to be collected by the collecting device pre-placed at the lower part of the guide plate 200. With the rotation of the conveying auger, the tea leaves with a diameter larger than the drying mesh holes of the arc-shaped screen drum 405 will be guided and transported by the conveying auger. The tea leaves are transported to the storage box, and after being screened for a certain period of time, the screening operation is stopped and the sealing plug is opened. At this time, the tea leaves in the storage box will fall through the discharge port at the bottom of the storage box, slide out through the guide hopper arranged at the bottom thereof and be collected by the pre-placed collection bucket, thereby realizing the screening and classification storage of the tea leaves, and the operation is more convenient and efficient. The utility model can realize the preliminary screening of the tea leaves by arranging a vibrating screening component 400 at the bottom of the tea separation box 1, and the screening is realized by the guide plates 200 arranged at an angle on the left and right sides of the tea separation box 1. The tea leaves after screening are guided, which solves the problem that the feed hopper 300 of the existing tea screening machine usually only has the function of conveying tea leaves, but does not have the function of preliminary screening of tea leaves. This leads to a large workload in the subsequent screening process of the tea leaves falling through the feed hopper 300, which can easily cause large and small tea leaves to be mixed together and blocked or fall together along the screen plate into the classification box, resulting in the tea leaves after screening still being mixed with tea leaves of different sizes, requiring manual secondary screening operations. Without manual secondary sorting, the operation is simpler, and the screening efficiency of the tea leaves is greatly improved.
[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0024] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
