[0026] In order to adjust the thickness of pumpkin seeds according to the needs and avoid uneven heating caused by inconsistent thickness of pumpkin seeds due to manual feeding, a seed leveling device 2 is provided on the upper side of one side of the frame 1 to level the pumpkin seeds. This device is used to adjust the leveling thickness according to the dryness or wetness of the pumpkin seeds.
[0027] like Figure 3 As shown, the seed leveling device 2 includes a feeding hopper 21, which is fixedly mounted on the upper end of the frame 1. Fixed frames 22 are fixedly mounted on both sides of the feeding hopper 21. The lower ends of the fixed frames 22 are fixedly connected to the upper end of the frame 1. A support frame 23 is fixedly mounted on the upper end of the frame 1. A threaded sleeve 26 passes through the inner side of the support frame 23. A threaded post 24 is threadedly connected to the inner side of the threaded sleeve 26. A turntable 25 is fixedly mounted on the upper end of the threaded post 24. A movable connecting seat 27 is movably mounted on the outer surface of the protrusion at the lower end of the threaded post 24. The movable connecting seat 27 is adapted to the protrusion at the lower end of the threaded post 24. A leveling plate 28 is fixedly mounted on the lower end of the movable connecting seat 27. The upper ends of the leveling plate 28 are respectively... A fixed limiting rod 29 is provided, with two limiting rods 29 passing through the inner through groove of the support frame 23. Pumpkin seeds are poured in through the feeding funnel 21, and the pumpkin seeds will flow out from the outlet of the feeding funnel 21.

The height of the spreading plate 28 can be adjusted by using the threaded connection between the threaded column 24 and the threaded sleeve 26, and by cooperating with the protrusion at the lower end of the threaded column 24 and the movable connecting seat 27. The limiting rod 29 slides within the support frame 23, which can achieve stable movement of the spreading plate 28. This allows the thickness of the pumpkin seeds to be spread according to the needs, avoiding the problem of uneven heating caused by uneven thickness of pumpkin seeds due to manual feeding.
[0028] Furthermore, in order to remove impurities from the surface of the pumpkin seeds by vibration and let the impurities fall into the recycling box 34, a vibrating screening device 3 is provided on the inner side of the frame 1, which can drive the porous track 8 to vibrate, and is used to vibrate the porous track 8 and the pumpkin seeds to screen out impurities such as debris and soil on the surface of the pumpkin seeds.
[0029] like Figure 4As shown, the vibrating screening device 3 includes a connecting plate 31, which is fixedly installed inside the frame 1. Both ends of the connecting plate 31 are fixedly connected to the inner walls of the frame 1.

When the pumpkin seeds are conveyed to the middle section of the dry heat sterilization box 4, the high temperature of the dry heat can dry the surface of the pumpkin seeds. When they reach the middle section, the vibration will remove impurities from the surface of the pumpkin seeds. Using the through holes of the perforated track 8, the impurities can fall into the recycling box 34, thereby improving the overall quality of the pumpkin seeds.
[0030] The working principle is as follows: When using this utility model, pumpkin seeds are poured into the feeding funnel 21. The thickness of the pumpkin seeds spread on the porous conveyor belt 8 is adjusted according to the dryness of the pumpkin seeds using the seed leveling device 2. The rotating motor 6 drives the rotating roller 7 to rotate, thus driving the porous conveyor belt 8. When the pumpkin seeds enter the middle section of the dry heat sterilization box 4, the impurities on the surface of the pumpkin seeds can be removed and screened by the vibrating screening device 3. After the impurities are removed, the pumpkin seeds continue to be dry heat sterilized at high temperature in the rear section of the dry heat sterilization box. After dry heat sterilization, the pumpkin seeds are discharged into the collection box through the guide plate 9. This improves the practicality of this utility model, avoids the problem of uneven heating of pumpkin seeds, and improves the overall quality of pumpkin seeds.
