[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0029] like Figures 1-4 As shown in the figure, this utility model provides a high-efficiency tea leaf air separation and destemming machine, including a screening box 1, a top cover 2, and a suction pump 8. The top cover 2 is snap-fitted to the screening box 1. It should be noted that locks are installed on the screening box 1 and the top cover 2 to lock their positions. The suction pump 8 is installed on the top cover 2, and a tea leaf suction box 7 communicating with the suction pump 8 is provided on one side of the suction pump 8. The tea leaf suction box 7 is inserted into the top cover 2. The suction pump 8 can generate suction to draw lighter tea leaves into it, thereby completing the separation and collection of tea leaves.
[0030] For reference Figure 3 , Figure 4 The screening box 1 is equipped with a screening plate 14, which is tilted to one side and is used to store tea leaves containing tea stems.
[0031] To allow the tea leaves to spread out and separate the tea stems, a vibration motor 3, support rods, a strong spring 4, and a support frame 5 are installed at the bottom of the screening box 1. The vibration motor 3 is installed on the screening box 1, and four support rods are installed at the four corners of the bottom of the screening box 1. The strong spring 4 is sleeved on the outside of the support rods. One end of the strong spring 4 is connected to the screening box 1, and the other end of the strong spring 4 is connected to the support frame 5. The support frame 5 includes vertical tubes and horizontal tubes. There are four vertical tubes, and the four vertical tubes are rectangularly distributed. Adjacent vertical tubes are connected by horizontal tubes. A base plate for support is provided at the bottom of the vertical tubes.
[0032] When the vibration motor 3 starts, it can cause the screening box 1 and the top cover 2 located above the support frame 5 to shake. The tea leaves on the upper side of the screening plate 14 in the screening box 1 are dispersed during the shaking. Under the action of wind, the tea stems in the tea leaves remain on the screening plate 14 because they are heavier, while the tea leaves are sucked away by the suction pump 8. At the same time, as the screening plate 14 shakes, the tea stems on the upper side of the screening plate 14 can move towards the side of the tea stem collection pipe 15, which facilitates the subsequent collection of tea stems.
[0033] To facilitate the feeding of raw materials, a feeding hopper 6 is provided on the top cover 2, and a tea stem collection pipe 15 is provided on the bottom side of the screening box 1 away from the feeding hopper 6. The screening plate 14 guides the tea stem collection pipe 15.
[0034] To accelerate the efficiency of air separation, a blower 9 is installed at the bottom of the screening box 1. An air inlet pipe 10 is installed at the air outlet of the blower 9. The air inlet pipe 10 is located at the bottom of the screening plate 14. Several exhaust ports 11 are installed inside the air inlet pipe 10. The blower 9 can generate airflow, which is discharged through the exhaust ports 11, forming an upward airflow. The airflow will blow the tea leaves on the screening plate 14, causing the tea leaves to float upwards, which assists the suction pump 8 in separating the tea leaves and tea stems.
[0035] In order to flatten the raw materials on the upper side of the screening plate 14, prevent the raw materials from piling up, and allow the wind to blow the lighter tea leaves, a flattening mechanism 13 is provided inside the screening box 1. The flattening mechanism 13 includes a rotating roller 1301, a drive device, and a push plate 1302. The drive device is connected to the rotating roller 1301 and is used to drive the rotating roller 1301 to rotate. The drive device is installed on the inner wall of the screening box 1. The drive device can be a motor. The output end of the motor is connected to the rotating roller 1301 through a coupling. The rotating roller 1301 is inserted into a bearing seat, and the bearing seat is installed on the inner wall of the screening box 1.
[0036] It should be noted that the push plate 1302 is installed on the outer wall of the rotating roller 1301. The push plate 1302 is located on the upper side of the screening plate 14, and the rotation direction of the push plate 1302 is opposite to the movement direction of the tea leaves on the screening plate 14.
[0037] The drive device can drive the rotating roller 1301 and the push plate 1302 to rotate. The push plate 1302 will push the tea leaves on the screening plate 14 that reach the height of the push plate 1302 to move towards the feed hopper 6. In this way, the upper layer of the pile of tea leaves on the screening plate 14 is pushed away by the push plate 1302, and the bottom layer of tea leaves moves to the other side of the push plate 1302 through the gap between the push plate 1302 and the screening plate 14. Under the action of the blower 9 and other components, the tea leaves and tea stems in the raw materials are separated. The tea leaves pushed by the push plate 1302 will be spread on the screening plate 14 when there are not many tea leaves on the screening plate 14.
[0038] To prevent blockage at the push plate 1302, a cavity is provided at the center of the rotating roller 1301, and a power pump 1304 is installed inside the cavity. Several through holes are provided inside the rotating roller 1301, and a baffle 1303 is provided on the outer side of the rotating roller 1301. The baffle 1303 is mounted on the screening box 1, and has an opening facing the feed hopper 6. A connecting groove is provided inside the push plate 1302 at the position corresponding to the baffle 1303. The baffle 1303 is installed in the screening box 1 via a bracket, and a break is provided in the push plate 1302 at the position corresponding to the bracket. (See reference...) Figure 3 , Figure 4 The rotating roller 1301 and the push plate 1302 can rotate synchronously. When rotating, the baffle 1303 attached to the outer wall of the rotating roller 1301 can rotate relative to the rotating roller 1301. The power pump 1304 is started, which can discharge gas from the through hole. However, most of the through holes are blocked by the baffle 1303, so the gas will only be discharged from the through hole at the bottom. The discharged gas will blow the raw material to move towards the side closer to the feed hopper 6, so as to prevent the raw material from jamming the push plate 1302.
[0039] In a specific embodiment, components such as baffle 1303 and rotating roller 1301 can also be installed on the top cover 2. As the top cover 2 is fastened to the screening box 1, the positions of components such as baffle 1303 and screening plate 14 are fixed.
[0040] In summary, this utility model embodiment provides a high-efficiency tea leaf air separation and stem removal machine. The driving device can drive the rotating roller 1301 and the push plate 1302 to rotate. The push plate 1302 will push the tea leaves on the screening plate 14 that reach the height of the push plate 1302 to move towards the feed hopper 6. In this way, the upper layer of the pile of tea leaves on the screening plate 14 is pushed away by the push plate 1302, and the bottom layer of tea leaves moves to the other side of the push plate 1302 through the gap between the push plate 1302 and the screening plate 14. Under the action of the blower 9 and other components, the tea leaves and tea stems in the raw materials are separated. The tea leaves pushed by the push plate 1302 will spread on the screening plate 14 when there are not many tea leaves on the screening plate 14. This can avoid the situation where the tea leaves cannot be completely screened due to the uneven thickness of the tea leaves falling on the screening plate 14.
[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
