Description

Technical Field

[0001] The utility model relates to the technical field of grain drying, in particular to a hot air structure applied to a grain dryer. Background Art

[0002] As we all know, when the temperature and humidity conditions in the grain environment meet the growth and reproduction of microorganisms, mildew will occur. That is to say, moisture and temperature are two important factors for the reproduction of microorganisms such as mold in grain. Generally speaking, controlling the moisture content of grain below the safe moisture content may prevent the grain from mildewing. At present, the method to reduce the moisture content of grain is natural drying. In the main grain producing areas, due to the large output and insufficient drying space, the moisture content of grain purchased by grain depots often exceeds the safe moisture content, which is the main factor causing the mildew of grain in grain depots. Therefore, it is necessary to use hot air furnaces to dry the grain. When the existing hot air furnaces are drying the grain, in order to ensure the drying effect, they usually only It is capable of drying grains of the same humidity. However, when drying grains of different humidity, the drying effect is poor. To solve the above problem, a technical solution is disclosed in Patent No.: CN202221738669.7. However, when using this technical solution, the distance between the supporting frame and the hot air blower is changed to change the volume of the hot air. Although this operation can change the volume of hot air for drying, due to the uncertain thickness of the grains laid on the supporting frame, the drying efficiency and air permeability cannot be fully guaranteed during drying, which in turn affects the efficiency and quality of the equipment during drying.

[0003] Based on this, the utility model designs a hot air structure applied to a grain dryer to solve the above problems. Utility Model Content

[0023] Among them, the lower side of the placing plate 3 is mesh-shaped, and the side of the placing plate 3 is provided with a convex edge; it is convenient to block the placed grains and prevent the grains from spilling when the paddle 11 is moved.

[0024] Among them, the number of separation tubes 6 is the same as the number of placement trays 3. The separation tubes 6 are located on the upper side of the placement tray 3. A plurality of air holes are opened on the dial plate 11. The nozzle 14 is located on the lower side of the placement tray 3. This facilitates the introduction of hot air flow into the grain in the placement tray 3, thereby accelerating the drying efficiency and quality.

[0025] Among them, the driving mechanism 15 includes a driving motor 16 and a speed regulating box 17. The driving motor 16 is installed on the box body 1, and the output end of the driving motor 16 is connected to the rotating shaft 2 by transmission. The speed regulating box 17 is installed on the box body 1, and the speed regulating box 17 is connected to the rotating shaft 2 by transmission.
