The bottom of the drying rack 2 is provided with casters, and the front and back of the drying tray 201 are provided with ventilation holes. The casters at the bottom of the drying rack 2 facilitate the positioning cover 303 to clamp and fix the drying rack 2, so that the reduction motor 3 drives the drying rack 2 to move in a circle inside the drying device body 1 through the positioning cover 303. This allows multiple drying racks 2 to be close to the hot air pipe 101, improving the uniform heating and drying of multiple drying racks 2 by the hot air pipe 101.

[0032] Reference Figures 4-6As shown in this embodiment: the top left side of the drying tray 201 is provided with a reciprocating slide groove that matches the connecting frame 204, and the top right side of the drying tray 201 is provided with a limiting slide rail that matches the connecting frame 204. The bottom plate 202 is fixedly connected to the bottom of the drying tray 201 by bolts, and the surface of the bottom plate 202 is also provided with ventilation holes. By moving the connecting frame 204 back and forth on the drying tray 201, the connecting frame 204 can drive the rake claw 205 to move back and forth, so that the rake claw 205 pushes the agricultural product particles on the drying tray 201 to move, so that hot air can come into contact with and heat the agricultural product particles through the ventilation holes on the surface of the bottom plate 202.

[0033] Reference Figures 2-6 As shown in this embodiment: the interior of the drying device body 1 is provided with a rotation space that matches the support plate 301 and the drying rack 2. The front of the connecting toothed ring 304 is provided with an inlet / outlet notch that matches the drying rack 2. The connecting toothed ring 304 meshes with the helical gear 206 through the tooth groove. Inclined push plates are provided on both sides of the bottom end of the rake claw 205. The inlet / outlet notch on the front of the connecting toothed ring 304 that matches the drying rack 2 facilitates the drying rack 2 to move out or in through the inlet / outlet notch.

The inclined push plates push the agricultural product particles on the drying tray 201 to turn over, which facilitates the full contact between the agricultural product particles and the hot air, thereby improving the heating efficiency of the agricultural product particles.

[0034] Working principle: By opening the cabinet door of the drying unit body 1, the user can push the drying rack 2 into the drying unit body 1, causing the top of the drying rack 2 to slide into the positioning cover 303. Then, the electric telescopic rod 302 is activated, causing it to move the positioning cover 303 downwards. The positioning cover 303 then engages with the top of the drying rack 2 through the limiting clamping groove, thus clamping and fixing the top of the drying rack 2. At this time, the controller starts the reduction motor 3, which drives the support plate 301 to rotate 90 degrees. The rotation of the support plate 301, through the electric telescopic rod 302 and the positioning cover 303, moves the drying rack 2 into the drying unit body 1. By repeating the above steps multiple times, multiple drying racks 2 can be dried in the drying unit. The internal installation and connection of the main body 1 is completed, and the cabinet door is closed. The controller then uses the hot air pipe 101 to deliver hot air to heat the drying trays 201 on the drying racks 2. At the same time, the geared motor 3 is started, which drives the support plate 301 to rotate. The rotation of the support plate 301, through the electric telescopic rod 302 and the positioning cover 303, causes multiple drying racks 2 to move in a circular motion inside the main body 1 of the drying device. This allows multiple drying racks 2 to approach the hot air pipe 101 on the left side of the main body 1 of the drying device, making the heating and drying time of the multiple drying racks 2 more uniform. This ensures that the multiple drying trays 201 on the drying racks 2 are evenly heated by the hot air, improving the heating uniformity of the agricultural product particles on the drying trays 201.

[0035] The drying rack 2 moves circumferentially inside the main body 1 of the drying device. The movement of the drying rack 2 drives the helical gear 206 on the drying tray 201 to rotate through the meshing of the toothed ring 304. The rotation of the helical gear 206 drives the reciprocating screw 203 to rotate. The rotation of the reciprocating screw 203 drives the connecting frame 204 to move back and forth on the drying tray 201. The reciprocating movement of the connecting frame 204 drives the rake claw 205 to move back and forth inside the drying tray 201. This allows the rake claw 205 to push and turn the agricultural product particles inside the drying tray 201 through the push plate. At the same time, the drying tray 201 has ventilation holes on the front and back and the surface of the bottom plate 202, which facilitates the hot air to fully contact the turned agricultural product particles, thereby improving the drying efficiency of the agricultural product particles and the uniformity of heating. This avoids uneven heating of the agricultural product particles during the drying process and improves the drying efficiency and quality of the agricultural product particles in the main body 1 of the drying device.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
