Technical Field

[0001] The utility model relates to the technical field of food processing, and particularly relates to a wind screening device for vegetable products. Background Technique

[0002] Dried plum vegetables are a kind of fermented food deeply loved by people. The traditional processing of dried plum vegetables is still mostly the traditional production of family workshops. When industrializing the production of dried plum vegetables, it is inevitable to automate each process step. Among them, the screening after cutting the dried plum vegetables is a process that consumes a lot of labor, and it is necessary to screen out dried plum vegetables of appropriate size according to needs.

[0003] The authorized announcement number is CN208768491U, which discloses a wind screening and cleaning machine. Combining its specification and drawings, its scheme is the design of the wind selection sequence and the falling distance of 30 mm to 40 mm. The discharged materials are conveyed to the inclined screen of the punching disc by the elevator through the feeding hopper. The discharged materials bounce back and forth on the inclined screen of the punching disc. At the same time, due to the centrifugal rotation of the inclined screen of the punching disc, the large impurities are separated from the grains. However, when adopting this scheme, it is impossible to realize the screening of the processed dried plum vegetables. At present, there is a particular lack of screening dried plum vegetables by the wind selection method in production. Summary of the Invention

[0018] The present utility model will be further described below in conjunction with the embodiments shown in the drawings:

[0019] As Figures 1 to 4 shown, a wind screening device for vegetable products includes a conveying assembly 1 and a support frame 2. The conveying assembly 1 includes a conveying frame 11, a driving shaft 12, a driving motor 13, a transmission chain 14 and a conveyor belt 15. Driving shafts 12 are provided at both ends of the conveying frame 11, and a conveyor belt 15 is drivingly connected between the driving shafts 12. A number of limiting baffles 16 are provided on the surface of the conveyor belt 15. One side of at least one driving shaft 12 is drivingly connected to the transmission chain 14, and the transmission chain 14 is drivingly connected to the driving motor 13. It should be noted that the support frame 2 and the conveying frame 11 are fixedly connected to each other by a number of aluminum metal profiles, so that better strength and supportability can be achieved. After such a setting, the rotating shaft of the driving motor 13 can drive the driving shaft 12 through the transmission chain 14, and the driving shaft 12 can drive the conveyor belt 15 when rotating. Workers can put the dried plum vegetables to be screened into the gaps between a number of limiting baffles 16, and thus the conveyor belt 15 can complete the transportation.

[0020] In this embodiment, a first bin 3 and a second bin 4 are provided on the support frame 2. A material guiding bin 7 is provided above the first bin 3. The discharging end of the conveyor belt 15 is inserted into the interior of the material guiding bin 7. The bottom of the material guiding bin 7 is open and faces the interior of the first inlet 31. A second bin 4 is provided on one side of the first bin 3. A blanking assembly 5 is provided between the first discharging port 32 of the first bin 3 and the second inlet 41 of the second bin 4. A blowing channel 6 is connected to the top of the second bin 4, and the blowing channel 6 is connected to an external blower. Whenever the blower operates, the blowing channel 6 can generate an upward suction force on the materials inside the second bin 4. A second discharging port 42 is provided at the bottom of the second bin 4. The first bin 3 includes a first chamber 33 and a second chamber 34, which are integrated. The cross-sectional area of the first chamber 33 is larger than that of the second chamber 34. The connection between the first chamber 33 and the second chamber 34 is an inclined surface, which can control the quantity of the dried plum vegetables falling. The second bin 4 includes a third chamber 43 and a fourth chamber 44, which are integrated. The cross-sectional area of the third chamber 43 is larger than that of the fourth chamber 44. Similarly, the connection between the third chamber 43 and the fourth chamber 44 is also an inclined surface, which can control the quantity of the dried plum vegetables falling, facilitating subsequent other transportation processes. The blanking assembly 5 includes a blanking baffle 51 and a lifting cylinder 52. One end of the blanking baffle 51 is inserted into the interior of the third chamber 43 through the second inlet 41. Both sides of the blanking baffle 51 are rotatably connected to the side wall of the third chamber 43 by means of hinges. A rotating shaft boss 53 is provided at the other end of the blanking baffle 51. The lifting cylinder 52 is installed on the support frame 2, and the end of the lifting cylinder 52 is rotatably connected to the interior of the rotating shaft boss 53. After such a setting, whenever the dried plum vegetables inside the first bin 3 fall onto the surface of the blanking baffle 51, the telescopic shaft of the lifting cylinder 52 will extend and push against the rotating shaft boss 53. In this case, when one end of the blanking baffle 51 receives an upward thrust, the blanking baffle 51 will rotate relative to the third chamber 43, and the dried plum vegetables on the surface of the blanking baffle 51 will gradually slide down under the inclined guiding action. At this time, the dried plum vegetables with too small a weight will fly upward under the suction force generated by the blowing channel 6, while the dried plum vegetables of appropriate size will fall into the outside through the fourth chamber 44. The rotation angle of the blanking baffle 51 determines the falling speed of the dried plum vegetables, which is beneficial to the adjustment of efficiency in production and brings convenience to production.

[0021] Working principle and usage method of the utility model:

[0022] First, the preserved vegetables to be screened are placed in the gap between several limit baffles 16. Then, the rotating shaft of the driving motor 13 can drive the driving shaft 12 through the transmission chain 14. When the driving shaft 12 rotates, it can drive the conveyor belt 15, and the conveyor belt 15 can transport the preserved vegetables into the interior of the material guiding bin 7. Then, the preserved vegetables will fall onto the surface of the blanking baffle 51 through the first bin 3. Next, the telescopic shaft of the lifting cylinder 52 will extend and push against the rotating shaft boss 53. In this way, when one end of the blanking baffle 51 receives an upward thrust, the blanking baffle 51 will rotate relative to the third chamber 43, and the preserved vegetables on the surface of the blanking baffle 51 will gradually slide down under the inclined guiding action. At this time, the preserved vegetables with too small a weight will fly upward under the suction force generated by the air blowing channel 6, while the preserved vegetables of the appropriate size will fall outside through the third chamber 43 and the fourth chamber 44 in sequence. Among them, the rotation angle of the blanking baffle 51 determines the falling speed of the preserved vegetables.
