Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing equipment, and particularly relates to a tea stem picking machine. Background Art

[0002] During tea preparation, a tea stem sorter is required to separate tea leaves from tea stems. Existing tea stem sorters are mostly vibrating screens, which use high-speed vibrations to separate tea leaves and tea stems as they move forward. However, existing tea stem sorters still have the following drawbacks: First, the screening portion of existing tea stem sorters is fixedly connected to the machine housing. While high-speed vibrations can separate tea leaves from tea stems, efficiency still needs to be improved. Second, there is a problem with the discharge port of the feed hopper. If the discharge port is too small, it can easily become clogged, affecting the screening process. If the discharge port is too large, a large amount of tea leaves can be discharged simultaneously, causing accumulation on the screen and resulting in incomplete screening of tea leaves and tea stems.

[0003] In view of this, in order to solve the above technical problems, the utility model proposes a tea stem picking machine which further improves the vibration efficiency of the original high-speed vibration screening of tea leaves and tea stems, effectively controls the tea discharge amount to avoid blockage and further separates the tea leaves and tea stems better. The tea stem picking machine has a simple structure and is easy to operate. Summary of the Invention

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See Figure 1-7 The tea leaves are picked up by the teacup 2 and the tea leaves are picked up by the teacup 2. The teacup 2 is a tea stalk picking machine, comprising a frame 1 and a casing 2 arranged on the frame 1. A feed hopper 3 is fixedly provided at one end of the casing 2. The upper end opening of the feed hopper 3 is larger than the lower end opening. A discharging paddle assembly 4 for controlling the discharging of the tea leaves is provided in the feed hopper 3. The discharging paddle assembly 4 is used to prevent the tea leaves from being blocked at the discharging end of the feed hopper 3 and to allow the tea leaves to be discharged evenly. An array screening assembly 5 is arranged from top to bottom in the casing 2. The array screening assembly 5 is arranged in a stepped shape, wherein the high end of the uppermost screening assembly 5 is located just below the discharging port of the feed hopper 3, and a tea discharging hopper 6 is provided on the lower side of the lowermost screening assembly 5. A tea stalk discharging hopper 7 is provided on the lower side of the bottom end of the array screening assembly 5. A vibration motor 8 is provided on the bottom surface of the casing 2, and an auxiliary vibration assembly 9 is provided on the casing 2 at the lower side of the array screening assembly 5. The auxiliary vibration assembly 9 is used to improve the vibration efficiency, thereby improving the speed of picking tea stems.

[0024] The auxiliary vibration component 9 includes a compression spring 901 and a fixed seat 902. The fixed seats 902 are horizontally provided on the casing 2 on both sides of the bottom surface of the array screening component 5. The compression spring 901 is arranged between the bottom end of the screening component 5 and the fixed seat 902 to support the screening component 5. When the vibration motor 8 is started, the screening component 5 can obtain more shaking power with its vibration force, so that the tea leaves and tea stems keep rolling.

[0025] The bottom surface of the screening component 5 is fixedly connected with a stepped fixing plate 903 adapted thereto, and the compression spring 901 is fixedly connected between the fixing plate 903 and the fixing seat 902. The stepped fixing plate 903 can securely connect the screening components 5 on the same layer together to improve stability.

[0026] The material diverter assembly 4 includes an electric telescopic rod 401 and a material diverter plate 402. The material diverter plate 402 is an inverted L-shaped structure and its horizontal part is located on the lower side. The material diverter plate 402 is arranged between the two sides of the inside of the feed hopper 3, and the two sides of the upper end of the material diverter plate 402 are respectively rotatably connected to the side walls of the feed hopper 3. The electric telescopic rod 401 is arranged on one side of the feed hopper 3. The output end of the electric telescopic rod 401 passes through the side wall of the feed hopper 3 and is hingedly connected to the side of the material diverter plate 402. When in use, it is only necessary to control and start the electric telescopic rod 401.

A stem-pushing roller 10 is provided between each pair of guide plates. The front side of the stem-pushing roller 10 has a slot for tea leaves to pass through. When the stem-pushing roller 10 rotates, the tea leaves can be pushed to the guide plate on the next layer and the tea stems can be pushed forward to the guide plate on the same layer. The plurality of stem-pushing rollers 10 are driven to rotate by a drive motor.

[0030] The end of the guide plate at the lower side of the feed hopper 3 is tilted upward and provided with a baffle plate 11 to prevent the tea leaves from falling to the rear side.

[0031] When the tea leaves fall from the bottom screening assembly 5 to the tea discharging hopper 6, the tea leaves can be discharged through it, thereby completing the separation of the tea stems from the tea leaves.
