[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 , an air-cooling drying device based on a rice dumpling production line, comprising a conveying frame 1 and an air-cooling device 2, a conveying device 3 is provided on the top of the conveying frame 1, and a plurality of brackets 4 are fixedly installed above the conveying device 3, and at least one of the air-cooling devices 2 is provided on the top of the bracket 4;

[0023] The air cooling device 2 includes a support frame 21, a flip cover 22 and an exhaust fan 7. The exhaust fan 7 is installed in the support frame 21, and its top is rotatably connected to the flip cover 22 through a rotating component 5. A filter 6 is detachably connected to the flip cover 22.

[0024] It should be added that the conveying device 3 includes a pair of rollers, which are rotatably connected to both sides of the top of the conveying frame 1, and a conveyor belt is arranged between them. A motor is fixedly installed on the side of the conveying frame 1, and the shaft end of the motor is connected to the end of one of the rollers;

[0025] In addition, when the exhaust fan 7 stops being used, closing the flip cover 22 can utilize the filter 6 to prevent external dust from adhering to the exhaust fan 7. Among them, when the flip cover 22 is kept open by the rotating component 5, it can avoid affecting the air intake of the exhaust fan 7.

[0026] Furthermore, the rotating assembly 5 includes a rotating rod 51, and the side of the support frame 21 is fixedly connected to the rotating rod 51 through a protrusion 211. The side of the flip cover 22 has a hinge part 221, and the hinge part 221 is arranged corresponding to the protrusion 211 and is rotatably connected to both ends of the rotating rod 51.

[0027] Furthermore, it also includes a fixing portion 52, which has a cylindrical structure and is recessed inward on one side to form a cavity. The fixing portion 52 is threadedly connected to one side of the hinge portion 221, and the center point of its end face passes through to form a through hole 521. The through hole 521 is adapted to the rotating rod 51. Of course, in other embodiments, an integral molding design can be adopted between the fixing portion 52 and the hinge portion 221 to avoid rotation and thereby improve the locking strength.

[0028] It is worth mentioning that a groove is provided on one side of the hinged portion 221, and one end of the rotating rod 51 is provided in the groove. The fixed portion 52 is adapted to the groove and is threadedly connected to the groove through internal and external threads. The fixed portion 52 avoids the rotating rod 51 through the through hole 521 and does not conflict with the rotating rod 51 to avoid getting stuck.

[0029] In more detail, the end face of the fixing portion 52 has a plurality of paving grooves 522 arranged in a circumferential array along the through hole 521, and an elastic portion 523 is formed by the paving grooves 522, and the end face of the elastic portion 523 has a protrusion 53, wherein one end of the rotating rod 51 has an extension portion 511, and the extension portion 511 is arranged between a pair of the protrusions 53 and slides in contact with the protrusion 53.

[0030] It should be noted that the fixing portion 52 is preferably made of a deformable material such as rubber or plastic. When the flip cover 22 rotates, the fixing portion 52 is driven to rotate. The protrusions 53 are provided on both sides of the extension portion 511. By abutting against the extension portion 511, the protrusions 53 create resistance when the flip cover 22 rotates, thereby preventing the flip cover 22 from rotating freely when opened.

[0031] The protrusion 53 is resisted by the extension portion 511 and deformed under the action of the clearance groove 522 , so as to avoid the extension portion 511 , thereby achieving the effect of adjusting the angle of the flip cover 22 .

[0032] In general, the cross-section of the flip cover 22 is a U-shaped structure, and its connected top forms an air inlet. The bottom of the flip cover 22 is relatively provided with at least a pair of through grooves, and a stop portion 222 is formed by the through grooves. The stop portion 222 is bent inward to form an L-shaped structure.

[0033] Finally, a baffle 223 is further provided at the bottom of the flip cover 22. The baffle 223 avoids the stop portion 222 through an opening 224 provided on the periphery. The opening 224 and the stop portion 222 can be staggered, wherein the filter 6 is provided between the baffle 223 and the flip cover 22.

[0034] In specific operation, the stopper 222 is bent into an L-shaped structure, and there is a certain gap between it and the inner side of the flip cover 22, and the filter 6 is placed in the gap;

[0035] Among them, the opening 224 is arranged corresponding to the stop part 222. After the baffle 223 passes through the opening 224 to avoid the stop part 222, the opening 224 and the stop part 222 are staggered by rotating the baffle 223. In this way, the baffle 223 cooperates with the stop part 222 to fix the filter 6, and the baffle 223 can be disassembled and replaced in the same way.

[0036] Working mode; when working, the dumplings are placed on the conveyor belt for transportation. During the transportation process, the exhaust fan 7 cooperates with the support frame 21 to blow and dry the dumplings;

[0037] Then, when the exhaust fan 7 is not in use, the flip cover 22 is rotated to close the opening of the support frame 21, and the filter 6 is used to prevent dust from adhering to the exhaust fan 7. In addition, when the flip cover 22 rotates, the fixed portion 52 is driven to rotate. As the fixed portion 52 rotates, the protrusion 53 abuts against the extension portion 511 and is deformed by the clearance groove 522, avoiding the extension portion 511, so that the flip cover 22 can be rotated.

[0038] After the flip cover 22 is rotated to a suitable position, the extension portion 511 is located between the protrusions 53 on both sides, and the protrusions 53 abut against the extension portion 511 to prevent the flip cover 22 from rotating freely.

[0039] Finally, the baffle 223 is rotated to align the opening 224 with the stopper 222 , and then the baffle 223 can be disassembled to facilitate replacement of the filter screen 6 .

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
