DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 6 As shown, a multi-layer nut automatic turning baking oven according to an embodiment of the present invention comprises a drying oven 1;

[0032] A drying frame 7 is slidably installed inside the drying box 1, a feed port 8 is provided at the top of the drying frame 7, a discharge port 9 is provided at the bottom of the drying frame 7, a plurality of drying frames 7 are provided, and ventilation holes are provided at the top and bottom of the drying frame 7;

[0033] A visual door 2 is rotatably mounted on the drying box 1;

[0034] Open the visual door 2, open the feed port 8 provided at the top of the drying frame 7, put the nuts into the drying frame 7, and after drying, open the discharge port 9 at the bottom to take the nuts out.

[0035] The interior of the drying frame 7 is hollow, and multiple drying frames 7 are arranged equidistantly up and down. The hot air inside the bottom drying frame 7 can enter the drying frame 7 located above through the ventilation holes opened on the top of the drying frame 7. Through the flow of hot air, the nuts in multiple drying frames 7 can be effectively dried at the same time.

[0036] A ventilation pipe 6 is rotatably installed inside the drying box 1, and a rotating plate 13 is provided on the outer wall of the ventilation pipe 6. The rotating plate 13 is provided with a cavity, and a plurality of air outlets 17 are provided on the rotating plate 13. The rotating plates 13 are all located inside the drying frame 7;

[0037] A drying assembly for conveying hot air toward the inside of the ventilation duct 6 is arranged inside the drying box 1 .

[0038] The hot air is transported to the interior of the ventilation duct 6 through the drying component. The hot air entering the ventilation duct 6 will flow upward, and then the hot air will be transported to the interior of the drying frame 7 through the multiple air outlets 17 opened on the rotating plate 13. The hot air can be directly transported to the interior of the drying frame 7 to directly contact the nuts, which can further improve the drying efficiency.

[0039] At the same time, when the ventilation pipe 6 rotates, it can drive the rotating plate 13 to rotate inside the drying frame 7. There are multiple rotating plates 13. When the multiple rotating plates 13 rotate, the nuts inside the drying frame 7 can be stirred to make the nuts roll inside the drying frame 7. By stirring the nuts while blowing hot air through the rotating plates 13, the drying effect of the nuts can be further improved.

[0040] The top of the ventilation duct 6 is sealed, so the hot air entering the ventilation duct 6 can only be discharged through the air outlet 17 opened on the rotating plate 13. At the same time, the hot air inside the drying frame 7 located at the bottom will also flow upward through the ventilation holes set on the drying frame 7 and pass through multiple drying frames 7, which can further improve the utilization rate of the hot air.

[0041] As a preferred embodiment of the present invention, the drying component includes a fan 3, a heating box 5 and a conveying pipe 14. The fan 3 is arranged on one side of the drying box 1, and the heating box 5 is fixedly installed inside the drying box 1. One end of the fan 3 extends to the inside of the heating box 5. One end of the conveying pipe 14 is fixedly connected to the heating box 5, and the other end is fixedly connected to the ventilation pipe 6.

[0042] By starting the fan 3, the air flow is transported to the interior of the heating box 5. At this time, the air flow entering the heating box 5 will be heated, and then the heated air flow will enter the interior of the ventilation pipe 6 through the conveying pipe 14, and then enter the interior of each drying frame 7 through the multiple air outlets 17 opened on the rotating plate 13.

[0043] As a preferred embodiment of the present invention, a transmission rod 15 is fixedly installed inside the ventilation pipe 6, one end of the transmission rod 15 passes through the conveying pipe 14 and extends to the inside of the drying box 1, and is rotatably connected to the inside of the drying box 1, and an impeller 16 is fixedly installed on the outer wall of the transmission rod 15.

[0044] When the hot air enters the interior of the ventilation pipe 6 through the conveying pipe 14, the airflow will impact the impeller 16 on the transmission rod 15, causing the impeller 16 to drive the transmission rod 15 to rotate. Since the transmission rod 15 is fixedly connected to the ventilation pipe 6, when the impeller 16 drives the transmission rod 15 to rotate, it will also drive the ventilation pipe 6 to rotate. At this time, the ventilation pipe 6 will drive multiple rotating plates 13 inside the drying frame 7 to stir the nuts while conveying hot air to the nuts to dry them.

[0045] As a preferred embodiment of the present invention, a transmission disk 18 is fixedly installed on the outer wall of the ventilation duct 6, and a top pressure block 19 is fixedly installed on the top of the transmission disk 18. There are multiple top pressure blocks 19, and the multiple top pressure blocks 19 are arranged in a ring shape on the top of the transmission disk 18. An arc-shaped top block 10 is fixedly installed on the bottom end of the drying frame 7, and a slider 12 is fixedly installed on the side wall of the drying frame 7. A slide groove 11 is opened inside the drying box 1, and one end of the slider 12 extends to the inside of the slide groove 11.

[0046] When the ventilation pipe 6 rotates, it will drive multiple top pressing blocks 19 to rotate and push the arc-shaped top block 10 at the bottom of the drying frame 7. When the arc-shaped top block 10 is located between the two top pressing blocks 19, the drying frame 7 will drive the slider 12 to be located at the bottom of the slide groove 11. When the ventilation pipe 6 drives the transmission plate 18 to rotate, so that the arc-shaped top block 10 is located at the top of the top pressing block 19, the drying frame 7 will drive the slider 12 to slide to the top of the slide groove 11, and then through the rotation of the transmission plate 18, the arc-shaped top block 10 is located in the gap between the two top pressing blocks 19 again. The drying frame 7 will slide down under the action of gravity and cause the nuts inside to vibrate. At the same time, when the drying frame 7 slides, the rotating plate 13 inside it will also change the height inside the drying frame 7, thereby achieving the effect of stirring nuts of different depths and improving the drying efficiency.

[0047] As a preferred embodiment of the present invention, an exhaust port is provided at the top of the drying box 1, and a filter screen 4 is provided inside the exhaust port.

[0048] When the ventilation pipe 6 drives the rotating plate 13 to stir the nuts, the dust on the nut skin will fly inside the drying box 1. The filter screen 4 can effectively filter the dust to prevent the dust from being discharged outside the drying box 1, thereby affecting the air quality.

[0049] As a preferred embodiment of the present invention, a placement box 20 is fixedly installed on the top of the ventilation pipe 6, and a film 21 is rotatably installed inside the placement box 20, and the outer wall of the film 21 is in contact with the bottom end of the filter screen 4.

[0050] When the ventilation pipe 6 rotates, it will also drive the placement box 20 to rotate at the same time. At this time, the rotating placement box 20 will drive the film 21 to rotate at the bottom end of the filter screen 4. Through the viscosity of the film 21, the dust filtered at the bottom end of the filter screen 4 is adhered, thereby ensuring the ventilation volume of the filter screen 4.

[0051] As a preferred embodiment of the present invention, a winding roller 22 is rotatably installed inside the placement box 20 , and one end of the film 21 is fixedly connected to the outer wall of the winding roller 22 .

[0052] By controlling the rotation of the winding roller 22, the tape on the surface of the film 21 can be torn off, and the tape with dust can be wound up, so that the new tape contacts the filter 4, ensuring the effect of the tape cleaning the dust at the bottom of the filter 4.

[0053] As a preferred embodiment of the present invention, a rotating groove is opened inside the drying box 1, and a rotating shaft 23 is fixedly installed on the axial end of the winding roller 22. One end of the rotating shaft 23 passes through the placement box 20 and extends to the inside of the rotating groove. A rotating gear 24 is fixedly installed on the outer wall of the rotating shaft 23, and a gear ring 25 is fixedly installed inside the rotating groove, and the rotating gear 24 is meshed with the gear ring 25.

[0054] When the ventilation pipe 6 rotates, it can drive the placement box 20 to rotate, and at the same time, the rotating shaft 23 will rotate inside the rotating groove. Through the cooperation of the gear ring 25 and the rotating gear 24 set inside the rotating groove, the placement box 20 can rotate and at the same time, the rotating shaft 23 drives the winding roller 22 to rotate, so that when the ventilation pipe 6 rotates, the bottom of the filter screen 4 can be cleaned at the same time.

[0055] Working principle: by starting the fan 3, the air flow is transported to the interior of the heating box 5. At this time, the air flow entering the heating box 5 will be heated, and then the heated air flow will enter the interior of the ventilation pipe 6 through the conveying pipe 14. When the hot air enters the interior of the ventilation pipe 6 through the conveying pipe 14, the air flow will impact the impeller 16 on the transmission rod 15, so that the impeller 16 drives the transmission rod 15 to rotate. Since the transmission rod 15 is fixedly connected to the ventilation pipe 6, when the impeller 16 drives the transmission rod 15 to rotate, it will also drive the ventilation pipe 6 to rotate. At this time, the ventilation pipe 6 will drive multiple rotating plates 13 inside the drying frame 7 to stir the nuts while transporting hot air to the nuts to dry them.

[0056] The ventilation pipe 6 drives multiple top pressing blocks 19 to rotate and push the arc-shaped top block 10 at the bottom end of the drying frame 7. When the arc-shaped top block 10 is located between the two top pressing blocks 19, the drying frame 7 will drive the slider 12 to be located at the bottom of the slide groove 11. When the ventilation pipe 6 drives the transmission plate 18 to rotate and makes the arc-shaped top block 10 located at the top of the top pressing block 19, the drying frame 7 will drive the slider 12 to slide to the top of the slide groove 11, and then through the rotation of the transmission plate 18, the arc-shaped top block 10 is located in the gap between the two top pressing blocks 19 again. The drying frame 7 will slide down under the action of gravity and cause the nuts inside to vibrate. At the same time, when the drying frame 7 slides, the rotating plate 13 inside it will also change the height inside the drying frame 7, thereby achieving the effect of stirring nuts of different depths and improving the drying efficiency.

[0057] When the ventilation pipe 6 rotates, it can drive the placement box 20 to rotate, and at the same time, the rotating shaft 23 will rotate inside the rotating groove. Through the cooperation of the gear ring 25 and the rotating gear 24 set inside the rotating groove, the placement box 20 can rotate and at the same time, the rotating shaft 23 drives the winding roller 22 to rotate, so that when the ventilation pipe 6 rotates, the bottom of the filter screen 4 can be cleaned at the same time.
