[0019] Below in conjunction with the attached Figures 1 to 3 , the technical solutions in the embodiments of the utility model are clearly and completely described, but the protection scope of the utility model is not limited to the following.
[0020] Example 1
[0021] A plant extract drying device, such as Figure 1 and Figure 2As shown, the drying device comprises a box body 100, a box door arranged on one side of the box body 100, and a plurality of placement plates 110 distributed vertically inside the box body 100, wherein the placement plates 110 have a circular cross section; in addition, the drying device further comprises a first connecting rod 120 arranged above each of the placement plates 110, a plurality of rake teeth 130 arranged at the bottom end of each of the first connecting rods 120, and a driving device for driving the first connecting rods 120 to rotate with the vertical axis of the placement plates 110 as the rotation axis. Further, as Figure 1 As shown, the driving device includes a vertical rod 140 arranged outside the placement plate 110 and connected to all the first connecting rods 120, an L-shaped rod 150 arranged at the top of the vertical rod 140, and a motor 160 arranged at the top of the box 100 and connected to the L-shaped rod 150. The axis of the vertical section of the L-shaped rod 150 is in line with the vertical axis of the placement plate 110. Further, the box 100 is also provided with a heating component (selecting a heating component of the prior art), such as heating tube heating, hot air heating, etc. If the heating tube is heated, the heating tube can be directly arranged on the inner wall of the box 100. If the hot air is heated, a fan is arranged outside the box 100, and an air duct is arranged at the air outlet end of the fan. The air outlet end of the air duct is connected to the inside of the box 100, and a heating wire is arranged in the air duct. Regardless of the heating method, air vents are arranged on the side wall or top wall of the box 100. Among them, the fan, air duct, heating wire and heating tube are all existing technologies and are not shown in the figure.
[0022] Working principle: Spread the plant extracts to be dried one by one on the placement plate 110, and then close the box door. Then turn on the heating component. Under the action of the heating component, heat can be generated in the box body 100 to heat the material. During the heating process, turn on the motor 160. Under the action of the motor 160, the L-shaped rod 150, the vertical rod 140, the first connecting rod 120, and the multiple rake teeth 130 are synchronously rotated with the vertical axis of the placement plate 110 as the rotation axis. During the rotation of the rake teeth 130, the material on the placement plate 110 can be scraped off, thereby improving the uniformity of heating of the material and improving the drying efficiency.
[0023] Further, such as Figure 1-2As shown, a rotating shaft 170 is vertically passed through the middle of the plurality of placement plates 110, and the bottom end of the rotating shaft 170 is rotatably connected to the bottom wall of the box body 100; the vertical projection of a section of the first connecting rod 120 located directly above the placement plate 110 is located inside one of the radii of the placement plate 110. In this solution, by connecting the plurality of placement plates 110 through the rotating shaft 170 and rotatably installing the rotating shaft 170 inside the box body 100, the plurality of placement plates 110 can be rotated with the rotating shaft 170 as the rotating shaft, thereby improving the convenience of taking and placing materials, such as rotating the materials inside the box body 100 to the outside for easy taking.
[0024] Further, such as Figure 1 and Figure 3 As shown, a plurality of second connecting rods 180 are disposed outside the rotating shaft 170, and an annular block 190 is commonly disposed at one end of the plurality of second connecting rods 180 away from the rotating shaft 170, and an annular groove 230 rotatably connected to the annular block 190 is disposed inside the box body 100 through a support rod. In this solution, the annular block 190 and the annular groove 230 can improve the rotation stability of the rotating shaft 170, thereby improving the rotation stability of the placement plate 110.
[0025] Furthermore, since the rake teeth 130 will slightly contact the placement plate 110 during the process of scraping the materials, and the placement plate 110 itself can rotate, the rake teeth 130 may drive the placement plate 110 to rotate, and then the rake teeth 130 and the placement plate 110 rotate synchronously, resulting in the failure of the scraping operation. Figure 2 As shown, a limit block 200 is provided on one side of the box door close to the box body 100, and a limit groove (not shown in the prior art, not shown in the figure) matching with the limit block 200 is provided on the side wall of the placement plate 110 located at the bottom. When drying, the limit groove on the placement plate 110 is first rotated to face the box door, and then the box door is closed. After the box door is closed, the limit block 200 is just inserted into the limit groove, thereby achieving the purpose of limiting the placement plate 110 and preventing it from rotating with the rake teeth 130.
[0026] Further, such as Figure 1 and Figure 2 As shown, an annular baffle 220 is provided around the edge of the placement plate 110. The annular baffle 220 can reduce the probability of material falling.
[0027] In the description of this patent, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "horizontal" and the like indicate the directions or positional relationships based on the attached Figure 1The orientation or positional relationship shown is only for the convenience of describing this patent and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of this patent.
