Problems solved by technology

[0002] At present, farmers who grow stevia in my country generally use manual methods to remove the leaves of stevia plants after shade drying. Although it is not easy to break the leaves of stevia, the speed of defoliation is slow and wastes manpower. Some people directly use soybean threshers to remove stevia. leaves, but because the principle of stevia defoliation is quite different from the threshing principles of various common crops, the rate of defoliation of stevia leaves with a soybean thresher is relatively high, and the defoliation speed is not fast enough, the defoliation is not clean, and the impurities contain Leaves, the protruding leaves contain a lot of stevia stalks and impurities, and the defoliation effect is not good. Due to the poor quality of the protruding stevia leaves, it directly affects the sales income of farmers

Embodiment 1

[0040] See figure 1 , A wind-driven stevia defoliation and collection integrated machine, comprising a defoliation warehouse 1, a collection warehouse 2, an air suction device 3, and an air duct 21. The defoliation warehouse 1 is used to defoliate the stems and leaves of the stevia Separation, the collection bin 2 is used to separate the blades from the air flow and collect the blades, the air duct 21 is connected to the defoliation bin 1 and the collection bin 2, and the suction device 3 is used to generate negative pressure to provide the air duct 21 and the collection bin 2 The air flow between the air guide tube 21 sucks the blades from the defoliation chamber 1 into the collection chamber 2.

[0041] See figure 2 , The specific structure of the defoliation bin 1 is as follows: the bin body is provided with a feed inlet 11 and a stem rod outlet 16, a first roller 12 and a second roller 13 are arranged up and down near the feed inlet 11 in the bin body, and the bin body is clo...

Embodiment 2

[0046] See figure 2 On the basis of Embodiment 1, the difference of this embodiment is that the specific operation modes of the first roller 12, the second roller 13 and the third roller 14 are:

[0047] The distance between the closest points of the first roller 12 and the second roller 13 is greater than the length of one elastic rod 15 and less than the length of the two elastic rods 15. The elastic rods 15 on the first roller 12 and the second roller 13 are mutually Staggered, the first roller 12 and the second roller 13 rotate in opposite directions;

[0048] The distance between the closest points of the second roller 13 and the third roller 14 is greater than the length of one elastic rod 15 and less than the length of the two elastic rods 15. The elastic rods 15 on the second roller 13 and the third roller 14 are mutually Staggered, the second roller 13 and the third roller 14 rotate in the same direction.

[0049] In this embodiment, the first roller 12 and the second rolle...

Embodiment 3

[0051] See image 3 On the basis of embodiment 1, the difference of this embodiment is that the collection bin 2 includes a cyclone separator 22 and a collecting hopper 24 that are connected to each other, and the cyclone separator 22 includes a cylindrical portion 223 and a cone portion 222. The part 223 is provided with a tangent inlet, the air inlet 221 is provided at the tangent inlet, the air outlet 224 is provided at the top of the cylindrical part 223, and the bottom of the cone part 222 is provided with a blade outlet 23, which is connected to the collecting hopper 24.

[0052] The cyclone separator 22 is used to separate the blades from the air flow. The separated blades reach the blade outlet 23 and fall into the collecting hopper 24. The separated air flow passes from the air outlet 224 to the suction port 31 of the suction device 3, and finally from the exhaust port 33 is discharged.

[0053] Furthermore, a pressure gate 241 is provided at the bottom of the collecting ...

Abstract

The invention discloses a wind-conveying type defoliation and collection integrated machine for stevia rebaudiana, relating to the technical field of defoliation of stevia rebaudiana. The machine comprises a defoliation bin, a collection bin, an air suction device and an air guiding pipe, wherein a feeding hole and a peduncle outlet are formed in a bin body of the defoliation bin, a first roller and a second roller are arranged on the upper and lower parts close to the feeding hole in the bin body, a third roller is arranged close to the peduncle outlet in the bin body, elastic rod bodies arerespectively fully distributed on the first roller, the second roller and the third roller along the radial direction, stevia rebaudiana is conveyed into a space between the first roller and the second roller and is subjected to peduncle-leaf separation, and the separated peduncles are discharged out of the defoliation bin by the third roller through the peduncle outlet. According to the wind-conveying type defoliation and collection integrated machine, the leaves are separated from the peduncles in the defoliation bin and are collected in the collection bin, so that the impurities are few, the leaf breaking rate is decreased, and the defoliation effect is good.

Description

Technical field [0001] The invention belongs to the technical field of stevia defoliation, and in particular relates to a wind transport type stevia defoliation and collection integrated machine. Background technique [0002] At present, farmers in China who grow stevia generally use artificial methods to defoliate stevia plants after shade drying. Although it is not easy to break the leaves of stevia, the defoliation speed is slow and wastes manpower. Some people directly use soybean thresher to defoliate stevia. But because the principle of defoliation of stevia is quite different from the principle of threshing of various common crops, the rate of breaking the leaves of stevia with soybean thresher is higher, and the defoliation speed is not fast enough, the defoliation is not clean, and the impurities are contained Leaves. The protruding leaves contain many stevia stems and impurities, and the defoliation effect is not good. Due to the poor quality of the protruding stevia le...
