At this time, the common practice of transporting them to the next process is to use a conveyor belt. However, this method not only has low transportation efficiency, but also has the problem of secondary pollution during the transportation process. In the field of transportation, how to transport vegetables by other transportation methods without secondary pollution is a problem that needs to be solved.

Combined with its specification and drawings, its scheme can form a closed chamber due to the enclosure component, the first conveyor belt and the two partitions running into the walking channel. In this way, the air source can blow the waste vegetables on the first conveyor belt through the air outlet pipe into the waste conveying pipe, and the waste conveying pipe discharges the waste vegetables to the garbage collection point. However, this method only simply blows away the waste vegetables, and cannot achieve fast and continuous transportation of vegetables while unloading. Summary of the invention

At this time, the direction of the airflow mainly tends to be downward. This method of pressing down the airflow prevents most of the airflow from leaking out through the first lower hopper, so mustard can be continuously put into the first lower hopper during the production process; the inclination angle of the second inclined plate matched with the first inclined plate can not only further limit the airflow from leaking out through the first lower hopper, at least more than 90% of the airflow will be retained and continue to flow to the inside of the circular air duct, and the mustard will also slide along the second inclined plate to the middle position of the entire square air duct, to ensure that the falling mustard moves along with the blowing of the airflow.

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figures 1 to 5As shown, a device capable of continuously unloading and conveying vegetables by wind power comprises an air supply mechanism 1 capable of generating wind power, an air duct pipeline 2 being connected to the air outlet end of the air supply mechanism 1, the air supply mechanism 1 comprises a motor support frame 11, a driving motor 12, a fan housing 13 and an impeller 14, a driving motor 12 and a fan housing 13 are provided on the surface of the motor support frame 11, an impeller 14 is provided inside the fan housing 13, a rotating shaft of the driving motor 12 is connected to the impeller 14, and the air duct pipeline 2 comprises a square air duct 21 and a circular air duct 22, the shapes of the square air duct 21 and the circular air duct 22 are relatively simple, and can reduce the resistance of air flow, one end of the square air duct 21 is connected to the air outlet of the fan housing 13, and the other end is connected to one end of the circular air duct 22, the power of the driving motor 12 The power is selected from 0.5kw to 22kw. One side of the circular air duct 22 is connected to a duct support column 221. The bottom of the air duct support column 221 is provided with a circular support plate 222. The height of the circular support plate 222 relative to the air duct support column 221 can be adjusted to adapt to different ground surfaces. After this arrangement, the rotation shaft of the driving motor 12 can drive the impeller 14 to rotate. During the rotation of the impeller 14, the air molecules will be pushed to cause the air to start flowing. The air is accelerated and pushed toward the air outlet of the fan housing 13. The wind will flow along the shape of the square air duct 21 and the circular air duct 22. It should be noted that the wind force generated by the impeller 14 can blow up the mustard greens and put them in a suspended state. At this time, the external vegetables enter the square air duct 21 and the circular air duct 22 and move along the direction of the airflow.

[0018] In this embodiment, the surface of the air duct 2 is provided with a plurality of feeding mechanisms 3, and the feeding mechanisms 3 include a first feeding hopper 31 for receiving vegetables and a second feeding hopper 32 for receiving auxiliary materials. The outlet size range of the bottom of the first feeding hopper 31 can be selected between 4 cm and 20 cm, and the outlet size range of the bottom of the second feeding hopper 32 can be selected between 0.5 cm and 10 cm. The number of the first feeding hopper 31 and the second feeding hopper 32 can be increased or decreased according to production needs, and the increase or decrease will not affect the conveying rate of the entire conveying device. The structural design is ingenious. The bottom of the first feeding hopper 31 is provided with a A first airflow guide 4 and a second airflow guide 5 which can follow the airflow direction are provided at the bottom of the second lower hopper 32. The first lower hopper 31 is arranged on the square air duct 21, and the second lower hopper 32 is arranged on the circular air duct 22. The outside of the second lower hopper 32 is connected with a hopper support column 321, and the bottom of the hopper support column 321 is connected to the surface of the circular air duct 22. The horizontal cross-sectional area of ​​the top of the first lower hopper 31 and the second lower hopper 32 is larger than the horizontal cross-sectional area of ​​the bottom. This arrangement enables the material to have a sliding tendency to fall downward when entering the first lower hopper 31 and the second lower hopper 32.

[0019] In this embodiment, the first airflow guide 4 includes a first inclined plate 41 and a second inclined plate 42. The length of the first inclined plate 41 is greater than that of the second inclined plate 42. One end of the first inclined plate 41 is connected to the inner wall of the square air duct 21. The other end of the first inclined plate 41 is connected to one end of the second inclined plate 42 and the end is lower than the center line of the square air duct 21 in the horizontal direction. The other end of the second inclined plate 42 is connected to the bottom of the first lower hopper 31. The side walls of the first inclined plate 41 and the second inclined plate 42 are both in contact with the inner wall of the square air duct 21. After such arrangement, the airflow coming out of the air outlet of the fan housing 13 is firstly continuously pressed downward under the guiding action of the first inclined plate 41. At this time, the air The direction of the flow tends mainly to be downward, and this downward pressure trend exceeds the leftmost end of the discharge port of the first lower hopper 31. The first inclined plate 41 thus presses down the airflow to prevent most of the airflow from leaking out through the first lower hopper 31. The inclination angle of the second inclined plate 42 further limits the airflow from leaking out through the first lower hopper 31. The two work together to retain at least 90 percent of the airflow and continue to flow into the circular air duct 22. Vegetables can be continuously placed into the first lower hopper 31 during the production process, and the vegetables will slide along the second inclined plate 42 to the middle position of the entire square air duct 21. Vegetables in this position are most likely to fly away with the blowing of the airflow.

[0020] In this embodiment, the second airflow guide 5 includes a third inclined plate 51 and a first horizontal plate 52. The third inclined plate 51 and the first horizontal plate 52 are hollow inside. Since some vegetables need to be pickled during production, for example, mustard greens need to be pickled, the second feed hopper 32 is mainly used to put some salt, water or other condiments into the air duct. The hollow feed method can prevent the airflow from dispersing to the outside through the third inclined plate 51 and the first horizontal plate 52. The first horizontal plate 52 is arranged inside the circular air duct 22 and is parallel to the airflow direction. One end of the third inclined plate 51 is connected to The bottom of the second lower hopper 32 is connected to one end of the first horizontal plate 52 at the other end. It should be noted that the side walls of the third inclined plate 51 and the first horizontal plate 52 are not in contact with the inner wall of the circular air duct 22. Since the first horizontal plate 52 is parallel to the wind direction, the material coming out of the end of the first horizontal plate 52 will first be transported to the next process along the air flow inside the circular air duct 22, and the wind inside the circular air duct 22 is difficult to leak out from the end of the first horizontal plate 52, so that seasoning or water can be added to the inside without affecting the transportation of mustard by the circular air duct 22, which can facilitate subsequent pickling.

[0021] Working principle and use method of the present invention: During the transportation of the washed mustard greens for pickling, the shaft of the driving motor 12 is first driven to rotate, which can drive the impeller 14 to rotate. During the rotation of the impeller 14, the air molecules are pushed, causing the air to start flowing. The air is accelerated and pushed to the air outlet of the fan housing 13, and the wind flows along the shape of the square air duct 21 and the circular air duct 22. The airflow coming out of the air outlet of the fan housing 13 is first continuously pressed downward under the guidance of the first inclined plate 41. At this time, the direction of the airflow mainly tends to be downward, and this downward pressure trend exceeds the leftmost end of the discharge port of the first lower hopper 31. Then, the first inclined plate 41 suppresses the airflow in such a way as to prevent most of the airflow from leaking out through the first lower hopper 31. The inclination angle of the second inclined plate 42 further limits the airflow from leaking out through the first lower hopper 31. The two cooperate with each other, and at least more than 90 percent of the airflow will be retained. Then, some salt, water or other condiments are put into the second lower hopper 32, and they will flow along the third inclined plate 51 and finally out from the end of the first horizontal plate 52. Since the first horizontal plate 52 is parallel to the wind direction, the material coming out from the end of the first horizontal plate 52 will first be transported to the next process along the airflow inside the circular air duct 22, and the wind inside the circular air duct 22 is difficult to leak out from the end of the first horizontal plate 52, thereby realizing the addition of condiments or water to the inside without affecting the circular air duct 22 to transport the mustard, which can facilitate the subsequent pickling.
