[0001] The invention relates to the technical field of food processing, and in particular to a vegetable turning and air-drying device and a use method thereof. Background Art

[0002] In recent years, with the continuous advancement of automation technology and intelligent control systems, vegetable flipping and air-drying equipment has made significant technological progress. The chain elevator smoothly delivers the vegetables into the air-drying area, and then the air-drying equipment flips the vegetables to the other side and continues to move to the next air-drying area. This method ensures that both sides of the vegetables can be dried evenly, while supporting continuous material flow and improving production efficiency.

[0003] Some vegetable turning and air-drying equipment in the prior art usually requires workers to manually deliver vegetables to the surface of the chain elevator according to the conveying frequency during use. If too many vegetables are piled on the chain elevator at one time, when the vegetables are piled together, the vegetables inside may not be able to fully contact the airflow generated by the air-drying equipment, resulting in uneven drying, which in turn affects product quality.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Example 1

[0036] Reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a vegetable turning and air-drying device, the device comprising:

[0037] The drying mechanism 100 includes a fixed frame 101, a chain elevator 102 adapted to be installed inside the fixed frame 101 and to cooperate with conveying and turning vegetables, a support frame 103 arranged outside the fixed frame 101, and a plurality of box-type fans 104 fixedly installed on the top of the support frame 103 and to cooperate with drying the moisture on the surface of the vegetables;

[0038] It should be noted that the fixed frame 101 is the basic frame of the chain hoist 102. The chain hoist 102 is used to transport and flip the vegetables. The vegetables are lifted to the maximum stroke and dropped by the chain hoist 102, so that the vegetables are flipped during the falling process to ensure that both sides of the vegetables can be evenly exposed to the drying airflow. The conveyor belt of the chain hoist 102 adopts a stainless steel partition material with a flat surface, good corrosion resistance and stable operation. It can provide sufficient support to prevent the vegetables from rolling downward due to gravity during the lifting process. At the same time, its partition structure allows water to pass smoothly to achieve the effect of drainage. The support frame 103 is used to support the box fan 104. The box fan 104 is used to blow dry the moisture on the surface of the vegetables and accelerate the flipping speed of the vegetables during their falling process.

[0039] The feeding mechanism 200 includes a bearing assembly 201 disposed outside the fixed frame 101 for collectively storing vegetables, a push-pull assembly 202 and a feeding assembly 203 disposed outside the bearing assembly 201 for intermittently feeding the vegetables in the bearing assembly 201 to the surface of the chain hoist 102;

[0040] The bearing assembly 201 includes a support platform 201a located at the entrance of the fixed frame 101, a fixing rod 201b fixedly connected to the top of the support platform 201a, a hollow frame 201c fixedly installed at the other end of the fixing rod 201b, and a discharge port 201d opened on the outer surface of the hollow frame 201c;

[0041] It should be noted that a ladder is connected to the entrance of the support platform 201a, which can facilitate the staff to carry vegetables close to the hollow frame 201c. The fixed rod 201b is used to support the hollow frame 201c so that the hollow frame 201c is in a suspended state. The hollow frame 201c is used to store vegetables in a centralized manner. The opening of the discharge port 201d can facilitate the staff to easily put the vegetables into the hollow frame 201c.

[0042] The push-pull assembly 202 includes a mounting frame 202a fixedly connected to the surface of the support platform 201a on the side away from the fixed rod 201b, a first servo motor 202b adapted to be installed on the outer surface of the mounting frame 202a, a first connecting column 202c installed on the output end of the first servo motor 202b through a coupling, and a reciprocating roller 202d fixedly connected to the through end of the first connecting column 202c.

[0043] Specifically, a bearing sleeve for cooperation and rotation is installed at the connection between the first connecting column 202c and the mounting frame 202a, and the outer end surface of the reciprocating roller 202d is fixedly mounted on the inner wall of the mounting frame 202a through the bearing.

[0044] Furthermore, the push-pull assembly 202 also includes a slider 202e movably connected to the outer surface of the reciprocating roller 202d, a connecting block 202f fixedly installed on the outer surface of the slider 202e through a bearing, and a guide block 202g fixedly connected to the top of the connecting block 202f.

[0045] The push-pull assembly 202 further includes a connecting rod 202h fixedly connected to the inner wall of the mounting frame 202a and used in conjunction with the connecting block 202f, and a guide rail 202i fixedly installed on the top of the supporting platform 201a through a support and used in conjunction with the guide block 202g.

[0046] It should be further explained that the first servo motor 202b is the driving source of the push-pull assembly 202, and can drive the first connecting column 202c and the reciprocating roller 202d to rotate synchronously through a coupling. The outer surface of the reciprocating roller 202d contains a series of spiral grooves, forming a thread-like effect. The structure of the slider 202e is in an arc shape, which can match the roller pattern on the surface of the reciprocating roller 202d. When the reciprocating roller 202d rotates, the roller pattern on its surface can drive the slider 202e to move along the reciprocating roller 202d. The slider 202e is limited by the connecting rod 202h and the connecting block 202f, so that the slider 202e can drive the connecting rod 202h, the connecting block 202f and the guide block 202g to move back and forth in a straight line through the rotation of the reciprocating roller 202d. The guide rail 202i is used to support the guide block 202g to ensure the smoothness of the movement process of the guide block 202g.

[0047] Preferably, the connecting block 202f is slidably mounted on the outer surface of the connecting rod 202h, and the inner surface of the guide block 202g is in sliding contact with the outer surface of the guide rail 202i.

[0048] Furthermore, the feeding assembly 203 includes a hollow plate 203a fixedly connected to the outer surface of the guide block 202g, a material distribution barrel 203b fixedly connected to the inner surface of the hollow plate 203a, and a barrel cover 203c hinged to the bottom of the material distribution barrel 203b through a hinge.

[0049] Furthermore, the feeding assembly also includes an extrusion plate 203d fixedly connected to the top of the supporting platform 201a and used in conjunction with closing the barrel cover 203c, and a shielding plate 203e fixedly connected to the outer side of the hollow plate 203a and used in conjunction with preventing the vegetables in the hollow frame 201c from leaking out.

[0050] It should be explained that when the guide block 202g drives the hollow plate 203a to move to the bottom of the hollow frame 201c, some vegetables in the hollow frame 201c will fall into the distribution barrel 203b through the hollow plate 203a and be blocked by the barrel cover 203c. When the guide block 202g drives the hollow plate 203a to move to a position close to the chain elevator 102, the barrel cover 203c gradually loses the force of the squeezing plate 203d. When the barrel cover 203c completely loses the force of the squeezing plate 203d, it opens due to the gravity of the vegetables, causing the vegetables in the distribution barrel 203b to fall to the surface of the chain elevator 102. At the same time, the shielding plate 203e follows the hollow plate 203a to move to the bottom of the hollow frame 201c, thereby preventing the vegetables in the hollow frame 201c from leaking out.

[0051] Specifically, when the material distribution barrel 203b is located directly below the first connecting column 202c, the inner cavity of the first connecting column 202c is communicated with the inner cavity of the material distribution barrel 203b.

[0052] Furthermore, the extrusion plate 203d is close to the end surface of the fixing frame 101 and is the force-applying end used to close the barrel cover 203c.

[0053] When in use, the vegetables are placed in the hollow frame 201c, and the chain elevator 102, the box fan 104 and the first servo motor 202b are turned on at the same time. The first servo motor 202b drives the first connecting column 202c and the reciprocating roller 202d to rotate synchronously, and the reciprocating roller 202d drives the driving slider 202e to move along the roller pattern on its surface, and then the slider 202e is limited by the connecting rod 202h and the connecting block 202f, so that the slider 202e can drive the connecting rod 202h, the connecting block 202f and the guide block 202g to move back and forth in a straight line. When the guide block 202g drives the hollow plate 203a to move to the bottom of the hollow frame 201c, the hollow frame 201c is The vegetables will fall into the material distribution barrel 203b through the hollow plate 203a and be blocked by the barrel cover 203c. When the guide block 202g drives the hollow plate 203a to move to a position close to the chain elevator 102, the barrel cover 203c gradually loses the force of the squeezing plate 203d. When the barrel cover 203c completely loses the force of the squeezing plate 203d, it is opened by the gravity of the vegetables, so that the vegetables in the material distribution barrel 203b fall to the surface of the chain elevator 102. The vegetables are lifted to the maximum stroke by the chain elevator 102 and fall down, so that the vegetables are turned over in the falling process. Then, the box-type fan 104 accelerates the turning speed of the vegetables in the falling process to ensure that both sides of the vegetables can be evenly exposed to the air drying airflow.

[0054] At the same time, the shielding plate 203e follows the hollow plate 203a to move to the bottom of the hollow frame 201c, thereby preventing the vegetables in the hollow frame 201c from leaking out. When 203a moves to a position away from the chain elevator 102, the barrel cover 203c gradually contacts the squeezing plate 203d and is closed by the reaction force of the squeezing plate 203d, so as to achieve the effect of closing the distributing barrel 203b and allowing the distributing barrel 203b to continue to collect some vegetables.

[0055] In summary, through the drying mechanism 100, the vegetables can be turned over during the falling process from the highest point, so that both sides of the vegetables can fully contact the airflow, thereby ensuring the uniformity of the vegetable drying; through the cooperation of the bearing component 201, the push-pull component 202 and the feeding component 203, through the cooperation of the bearing component 201, the push-pull component 202 and the feeding component 203, the piles of vegetables can be evenly and orderly delivered to the surface of the chain elevator 102, and each vegetable can be evenly air-dried without manual operation, so as to achieve the effect of improving the overall drying efficiency and quality.

[0056] Example 2

[0057] Reference Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a method of use, including a vegetable flipping and air-drying device.

[0058] S1: Put the vegetables in the hollow frame 201c, and start the chain elevator 102, the box fan 104 and the first servo motor 202b at the same time, so that the first connecting column 202c and the reciprocating roller 202d are driven to rotate synchronously by the first servo motor 202b;

[0059] S2: The reciprocating roller 202d drives the driving slider 202e to move along the roller pattern on its surface, and then the slider 202e is limited by the connecting rod 202h and the connecting block 202f, so that the slider 202e can drive the connecting rod 202h, the connecting block 202f and the guide block 202g to move reciprocatingly in a straight line;

[0060] S3: When the guide block 202g drives the hollow plate 203a to move to the bottom of the hollow frame 201c, the vegetables in the hollow frame 201c will fall into the distribution barrel 203b through the hollow plate 203a and be blocked by the barrel cover 203c. When the guide block 202g drives the hollow plate 203a to move to a position close to the chain elevator 102, the barrel cover 203c gradually loses the force of the squeezing plate 203d. When the barrel cover 203c completely loses the force of the squeezing plate 203d, it opens by the gravity of the vegetables, causing the vegetables in the distribution barrel 203b to fall onto the surface of the chain elevator 102.

[0061] In summary, through the drying mechanism 100, the vegetables can be turned over during the falling process from the highest point, so that both sides of the vegetables can fully contact the airflow; through the cooperation of the bearing component 201, the push-pull component 202 and the feeding component 203, through the cooperation of the bearing component 201, the push-pull component 202 and the feeding component 203, the piles of vegetables can be evenly and orderly delivered to the surface of the chain elevator 102, and each vegetable can be evenly air-dried without manual operation.

When the guide block drives the hollow plate to move to a position close to the chain elevator, the barrel cover gradually loses the force of the squeezing plate. When the barrel cover completely loses the force of the squeezing plate, it opens by the gravity of the vegetables, causing the vegetables in the distribution barrel to fall onto the surface of the chain elevator.
