[0002] Stevia, also known as stevia leaves, sugar grass, and sweet grass, is a perennial herbaceous stem of the Asteraceae family. It is a natural sweet plant. The whole plant of stevia is sweet, and the leaves are the sweetest. They are widely used as sweeteners. Stevia leaves are a natural, green, and healthy functional beverage with a fragrant and refreshing taste. Stevia leaves are 30 times sweeter than sucrose, and the extracted stevioside is 300 times sweeter than sucrose, but the calories are very low. Its leaves are also rich in protein, cellulose, carbohydrates, iron, phosphorus, calcium, potassium, sodium, magnesium, zinc, rutin, vitamin C, vitamin A, and about 53 other ingredients.

[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a stevia leaf remover.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The present invention discloses a stevia leaf remover, comprising a leaf remover box fixed on a frame, a partition is fixed in the leaf remover box, a blower motor is fixed in the leaf remover box below the partition, a plurality of blower blades are evenly fixed on the output end of the blower motor, an air outlet pipe is fixed on the partition, a slag discharge pipe is also fixed on the partition, a vibration plate is arranged in the leaf remover box above the air outlet pipe, through holes penetrating the vibration plate are evenly arranged on the vibration plate, a feed port is also arranged on the leaf remover box above the vibration plate, and a machine A support ring is also fixed on the frame, and a suction cup rotatably connected to the support ring is provided on the support ring, and suction holes are evenly provided on the suction cup, and the suction cup is driven to rotate by a suction motor, and a material receiving box is also fixed on one side of the defoliation box, and a material receiving pipe is also fixed on the bottom of the material receiving box, and a suction barrel is also fixed on the frame above the suction cup and at a position corresponding to the defoliation box, and the suction barrel is connected to the defoliation box under the partition through the suction pipe, and a material receiving barrel is also fixed on the frame above the suction cup and at a position corresponding to the material receiving box, and an exhaust fan is also fixed on the material receiving barrel. The stevia leaves to be separated from the stems are discharged into the vibrating plate through the feed port, and the blower motor drives the blower blades to rotate. The blower blades push the air to form an airflow. The airflow passes through the air outlet pipe and enters the top of the vibrating plate. The airflow pushes the stevia leaves to fly above the vibrating plate. When the blower blades rotate, the air at the suction pipe position in the defoliation box forms an airflow, and a negative pressure is formed in the suction barrel. A negative pressure is formed at the suction hole position of the suction cup at the suction barrel position. The flying leaves are adsorbed on the suction hole, and the suction cup is driven to rotate by the suction motor. The leaves adsorbed on the suction cup move with the suction cup, and the suction After the disc moves to the top of the collecting box, the exhaust fan on the collecting barrel above the collecting box starts to work, and air enters the collecting barrel from outside the collecting barrel. After the blades reach the position of the collecting barrel, they fall into the collecting barrel and are collected and then discharged through the collecting pipe. Due to the small area of ​​the stem rods, the airflow cannot push the stem rods to fly. After the blades fly, the stem rods fall onto the vibrating disc, and the stem rods fall through the through holes to the bottom of the vibrating disc and are discharged and collected through the slag discharge pipe. This device can separate the stevia leaves from the stem rods, and the leaves are adsorbed at the suction hole position and then fall into the collecting box for collection, without damaging the stevia leaves.

The vibration motor drives the cam to rotate, and due to the action of the support springs, the vibration disk is attached to the cam surface, so that the vibration disk can vibrate up and down, and the stevia leaves are spread flat on the vibration disk.

[0010] Preferably, the air outlet pipe is also provided with a turntable rotatably connected to the air outlet pipe, the turntable is provided with an air outlet penetrating the turntable, a rotating rod is fixed to the turntable, and rotating blades are fixed to the rotating rod in the air outlet pipe. When the airflow flows in the air outlet pipe, the turntable is driven to rotate by the rotating blades, and the airflow is blown out from the air outlet, so that the airflow is gathered at the air outlet position, the flow rate of the airflow is increased, and the blades are flying.

[0021] The embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0022] Embodiment 1:

A support ring 23 is fixed, and a suction cup 21 rotatably connected to the support ring 23 is arranged on the support ring 23. Suction holes 24 are evenly arranged on the suction cup 21. The suction cup 21 is driven to rotate by a suction motor 22. A material collecting box 27 is also fixed on one side of the defoliation box 1, and a material collecting pipe is also fixed at the bottom of the material collecting box 27. A suction barrel 28 is also fixed on the frame at a position corresponding to the defoliation box 1 above the suction cup 21. The suction barrel 28 is connected to the defoliation box 1 below the partition 3 through a suction pipe 29. A material collecting barrel 30 is also fixed on the frame at a position corresponding to the material collecting box 27 above the suction cup 21, and an exhaust fan 31 is also fixed on the material collecting barrel 30. The stevia leaves to be separated from the stems are discharged into the vibrating plate 14 through the feed port 2, and the blower motor 6 drives the blower blades 7 to rotate. The blower blades 7 push the air to form an airflow. The airflow passes through the air outlet pipe 9 and enters the top of the vibrating plate 14. The airflow pushes the stevia leaves to fly above the vibrating plate 14. When the blower blades 7 rotate, the air at the suction pipe 29 in the defoliation box 1 is sucked to form an airflow, and a negative pressure is formed in the suction barrel 28. A negative pressure is formed at the suction hole 24 on the suction cup 21 at the suction cup 28. The flying leaves are adsorbed on the suction hole 24, and the suction cup 21 is driven to rotate by the suction motor 22. The leaves adsorbed on the suction cup 21 move with the suction cup 2 1 moves, after the suction cup 21 moves to the top of the material receiving box 27, the exhaust fan 31 on the material receiving barrel 30 above the material receiving box 27 works, and air enters the material receiving barrel 30 from the outside. After the blades reach the position of the material receiving barrel 30, they fall into the material receiving barrel 30 for collection and are discharged through the material receiving pipe. Due to the small area of ​​the stem rod, the airflow cannot push the stem rod to dance. After the blades dance, the stem rod falls onto the vibration plate 14, and the stem rod falls through the through hole to the bottom of the vibration plate 14 and is discharged and collected through the slag discharge pipe 5. The device can separate the stevia leaves from the stem rod, and the leaves are adsorbed at the position of the suction hole 24 and then fall into the material receiving box 27 for collection, without damaging the stevia leaves.
