Description

[0001] The invention belongs to the technical field of agricultural product drying, and in particular relates to an energy-saving circulating drying system for agricultural products. Background Art

[0002] Modern agriculture is developing rapidly, and the level of mechanization and scientific planting is constantly improving. The quality and output of various plant agricultural products have increased significantly. After being harvested, these plant agricultural products must go through multiple links such as procurement, transportation, and sales before they can reach consumers. These links require a long time and take up a lot of processing space. Some products with high water content not only take up a lot of space and weight, but are also easily damaged or rotten during transportation and sales. In order to sell a large amount of plant agricultural products, farmers will process many plant agricultural products that cannot be purchased in time. This processing is freezing or dehydrating plant agricultural products with high water content. However, freezing cannot reduce the volume and weight, while dehydration can reduce the volume and weight, and can be stored for a longer time. To remove water and reduce the volume of plant agricultural products, farmers generally spread them out for airing. This drying efficiency is low and is greatly affected by the weather, which cannot effectively meet the needs. Therefore, the utility model designs an energy-saving circulating drying system for agricultural products, thereby solving the above problems. Technical issues

The first U-shaped sealing plate 503 and the second U-shaped sealing plate 507 are both components made of rubber material. Through the combined use of the first U-shaped sealing plate 503 and the second U-shaped sealing plate 507, the drying box body 501 and the drying box door 506 can be connected more tightly.

[0049] A U-shaped handle 508 is fixedly mounted on the front surface of the drying box door 506 . A protective ring is sleeved on the outer side of the U-shaped handle 508 . The protective ring is a rubber component.

[0050] The diameter of the rotating roller 6011 is the same as the inner diameter of the circular through hole 505 , and the peripheral side surface of the rotating roller 6011 and the inner wall of the circular through hole 505 are both smooth.

[0051] A motor support 6015 is fixedly mounted on the back of the drying box 501 , and a driving motor 6016 is fixedly mounted on the motor support 6015 .

[0052] The sliding collar 6030 and the blocking ring 6031 are both sleeved on the outside of the first material storage barrel 6022 , and mesh holes are provided on the first material storage barrel 6022 , the second material storage barrel 6023 and the blocking ring 6031 .

[0053] A guide hole is formed inside the guide block 6032 , and the connecting post 6024 passes through the guide hole. The diameter of the connecting post 6024 is the same as the inner diameter of the guide hole, and the peripheral side surface of the connecting post 6024 and the inner wall of the guide hole are both smooth.

[0054] When it is necessary to dry the agricultural products, the staff first pushes the energy-saving circulating drying system for agricultural products of the present invention to a suitable position through the mobile roller 2 on the lower surface of the supporting base plate 1. After the energy-saving circulating drying system for agricultural products of the present invention is pushed to a suitable position, the brake pads on the mobile roller 2 are used to fix the energy-saving circulating drying system for agricultural products of the present invention to avoid the energy-saving circulating drying system for agricultural products of the present invention from moving when the agricultural products are being dried, thereby affecting the drying. When the energy-saving circulating drying system for agricultural products of the present invention is fixed in a suitable position, the energy-saving circulating drying system for agricultural products of the present invention is prevented from moving when the agricultural products are being dried, thereby affecting the drying. After the drying device 3 is in the appropriate position, the control switch of the first electric telescopic rod 4 is activated. The first electric telescopic rod 4 will shrink and drive the drying device 3 to tilt. When the drying device 3 is tilted to a certain angle, the staff will hold the "U"-shaped handle 508 to open the drying box door 506, and then activate the control switch of the second electric telescopic rod 6029. The second electric telescopic rod 6029 will drive the blocking ring 6031 to move downward through the sliding ring 6030. At this time, the blocking ring 6031 will no longer block the feed inlet. Since the drying device 3 is in a tilted state, the storage device 602 will also be in a tilted state. At this time, the agricultural products to be dried can be poured into the interior of the storage device 602, and then the second electric telescopic rod 6029 will be activated. The electric telescopic rod 6029 blocks the feed port of the storage device 602. After the feed port of the storage device 602 is blocked, the control switch of the first electric telescopic rod 4 is started, so that the first electric telescopic rod 4 is extended as a whole, so that the drying device 3 is in a vertical state. Then the drying box door 506 is closed and the control switch of the drive motor 6016 is started at the same time. The drive motor 6016 will drive the rotating roller 6011 to rotate, thereby rotating the storage device 602 between the connecting plates 6012. The rotation of the rotating roller 6011 drives the large gear 6013 to rotate. Since the large gear 6013 and the small gear 6026 are meshed and connected, the rotation of the large gear 6013 can drive the small gear 6026 to rotate. 026 rotates, thereby driving the storage device 602 to rotate. The storage device 602 can rotate while revolving, and the agricultural products inside it will continue to roll. Then, by starting the control switch of the heater 701, the heater 701 will convey hot air to the interior of the drying box 501 through the diverter pipe 703 and the air outlet 704, thereby drying the agricultural products inside the storage device 602. Since the storage device 602 can rotate while revolving, the agricultural products inside it will continue to roll, thereby increasing the contact area between the agricultural products and the hot air, thereby improving the drying effect. In addition, the present invention can sterilize the interior of the drying box 501 by arranging the ultraviolet sterilization lamp 502.

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
