Description

Technical Field

[0001] The utility model relates to a drying device, specifically to a seed forced-air drying device. Background Art

[0002] In the process of seed production and storage, seed drying is an important link. By reducing the moisture content of seeds, the respiration of seeds and the growth and reproduction of microorganisms can be inhibited, the physical properties can be made more stable, and the occurrence of mildew, heating, germination and other adverse phenomena can be reduced, thereby prolonging the lifespan of seeds. For the convenience of research, seeds also need to be dried in the laboratory.

[0003] The electrothermal constant-temperature forced-air drying oven is a common laboratory drying equipment. Its structure is that a heating fan is arranged on the rear wall of the box body, a storage rack is arranged inside, and an air outlet is arranged at the top. During drying, the items are placed on the storage rack, the heating fan blows hot air into the box, and after the hot air flows through the surface of the items, it is discharged from the air outlet to achieve the drying purpose. When using the electrothermal constant-temperature forced-air drying oven to dry seeds, the seeds are generally placed on a tray. To ensure the drying effect, during the drying process, it is necessary to ensure the uniform heating and ventilation of the seeds to avoid local overheating or over-drying. In the prior art, generally, the box door is opened and the seeds are turned regularly. Due to the high temperature inside the box, this operation method has certain dangers and the operator is prone to injury.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a seed forced-air drying device, including a box body, a box door arranged on the front side of the box body, a heating fan arranged on the rear wall of the box body, and a storage rack arranged inside the box body. The storage rack includes four lifting rods, at least one layer board, and multiple pairs of layer board support grooves fixed on the inner walls of the left and right sides of the box body. The two side edges of the layer board extend into the layer board support grooves, and the layer board support grooves are provided with a shaking space for the layer board to move up and down. The four lifting rods are inserted through the four corners of each layer board, and four air outlets are opened at the four corners of the top wall of the box body. The top ends of the four lifting rods extend out from the four air outlets.

[0007] Based on the above, the shelf board includes a rectangular frame, two clips arranged at the front of the rectangular frame, and two card slots arranged at the rear of the rectangular frame. The middle of the rectangular frame is for the bottom of the tray to pass through, and the frame body is for supporting the edge of the tray. The two clips are for clamping the front edge of the tray, and the two card slots are for clamping the rear edge of the tray.

[0008] Based on the above, the lifting rod includes a threaded section and a clamping nut installed on the threaded section. The shelf board is provided with a through hole corresponding to the threaded section. The threaded section passes through the through hole and clamps the shelf board through the clamping nut.

[0009] Based on the above, a handle is provided at the top of the lifting rod.

[0010] Based on the above, an observation window is provided on the box door.

[0011] The present utility model has substantial features and progress compared with the prior art. Specifically, the shelf board in the present utility model is used to place the tray for holding seeds. By providing four lifting rods, and the lifting rods pass through the air outlet at the top, the shelf board can be lifted from the outside of the box body, so that the shelf board can move up and down in the shaking space, driving the seeds to turn over. It has the advantages of scientific design, being able to turn over the seeds without opening the box door, not being easy for operators to get injured, and strong practicability.

[0012] Furthermore, the edge of the tray is framed by the rectangular frame, the rear edge of the tray is clamped into the card slot, and the front edge of the tray is clamped by the clip, realizing firm fixation of the tray, avoiding the jumping amplitude of the tray getting out of control when turning over the seeds, and only setting the clip in the front, which is convenient for operation; the setting of the clamping nut can adjust the height according to the position of the shelf board and is convenient for the disassembly and assembly of the lifting rod; the setting of the handle is convenient for lifting the lifting rod, and the observation window is convenient for observing the turning over and drying conditions of the seeds.
