Description

Technical Field

[0001] This utility model relates to a drying device, specifically a low-temperature drying box for crop seeds, belonging to the field of agricultural equipment technology. Background Technology

[0002] To ensure rice can be planted the following year, seeds are typically saved for future planting. This requires reducing the moisture content of the seeds to a certain level for stable preservation and to prevent mold growth. Currently, there are two common methods for drying seeds: one involves spreading the seeds flat on the ground and drying them in the sun, but this method is time-consuming, requires regular turning, and is greatly affected by weather conditions; the other uses a dryer, where the seeds are spread flat on drying trays and dried using the dryer's temperature. This method is unaffected by external weather and can be continuous. However, because the seeds remain stationary on the trays, the two sides dry at different rates, requiring manual turning, making it difficult to control the drying process and resulting in less than ideal drying outcomes.

[0003] Therefore, a low-temperature drying box for crop seeds is proposed here. Utility Model Content

[0004] This invention proposes a low-temperature drying box for crop seeds to solve the problems in the prior art where the two sides of the seeds need to be dried at different speeds, requiring manual turning, making it difficult to control the degree of drying and resulting in poor drying effect.

The box body moves on the upper surface of the base through the adjustment component. A filter plate and a limiting component are also provided inside the box body. The filter plate is fixed to the side of the box body through the limiting component.

[0006] The adjustment assembly includes a motor, the base has a transmission chamber inside, the motor is fixed to the inner wall of the transmission chamber, the output end of the motor is fixed to a rotating plate, the surface of the rotating plate is hinged to a connecting rod, the side of the motor is provided with a connecting plate, the other end of the connecting rod is hinged to the surface of the connecting plate, and the upper surface of the connecting plate is fixed to the lower surface of the housing.

[0007] The box body has a drying chamber inside, and the inner wall of the drying chamber is fixed with a temperature guide plate. There are multiple temperature guide plates, which are arranged in a zigzag pattern.

[0008] Furthermore, the surface of the box is provided with a feed inlet, which is connected to the drying chamber. The feed inlet is located above the temperature guide plate. A guide plate is fixed on the inner wall of the drying chamber. An air inlet pipe is also provided on the side of the box. One end of the air inlet pipe passes through the guide plate, and the other end of the air inlet pipe is connected to an external air supply device.

[0009] Furthermore, a first slider is fixed on the lower surface of the housing, and a first groove is provided on the upper surface of the base. The first slider moves in the first groove. The housing moves on the upper surface of the base via a motor, a rotating plate, a connecting rod, a connecting plate, the first slider, and the first groove. There are two first sliders and two first grooves, which are symmetrically arranged on the lower surface of the housing.

[0010] Furthermore, a second slider is fixed on the lower surface of the connecting plate, and a second groove is provided on the inner wall of the transmission chamber. The second slider moves inside the second groove, and the connecting plate moves inside the transmission chamber via a motor, a rotating plate, a connecting rod, the second slider, and the second groove.

[0011] Furthermore, the limiting component includes a support rod, a limiting groove is formed on the surface of the housing, one end of the support rod is fixed to the inner wall of the limiting groove, a limiting rod is sleeved on the surface of the support rod, a limiting groove corresponding to the limiting rod is formed on the surface of the filter plate, one end of the limiting rod is engaged in the limiting groove, a lever is fixed to the side of the limiting rod, a movable groove is formed on the surface of the housing, the limiting groove is connected to the movable groove, one end of the limiting rod passes through the movable groove, and a spring is sleeved on the surface of the support rod.

[0012] Furthermore, the limiting component also includes a limiting block fixed to the side of the housing, and a fixing rod is hinged to the side of the housing. The limiting block and the fixing rod are respectively disposed on both sides of the lever. The surface of the limiting block is provided with a fixing groove corresponding to the fixing rod, and the fixing rod can be engaged in the fixing groove.

[0013] Furthermore, a discharge port is provided at the bottom of the drying chamber, and a temperature sensor is fixed on the side of the drying chamber.

[0014] This utility model provides a low-temperature drying box for crop seeds, which has the following beneficial effects:

[0015] 1. This low-temperature drying oven for crop seeds pours crop seeds into the drying chamber through the feed inlet. The seeds then move from top to bottom on the temperature guide plate. During this movement, the position of the seeds changes. The upper and lower air inlets and the guide plate can introduce hot air into the drying chamber, allowing it to fully contact the tumbling seeds. This avoids over-drying or under-drying due to uneven temperature or humidity, and directly acts on the seed surface, improving the efficiency of heat exchange and facilitating the rapid reduction of moisture on the seed surface.

[0016] 2. The low-temperature drying box for crop seeds is driven by a motor to rotate a rotating plate. The rotating plate drives the connecting rod and the connecting plate hinged to the other end of the connecting rod to move, causing the box to reciprocate. This prevents the damp seeds from clumping on the temperature-conducting plate, which would cause uneven drying. At the same time, different sides of the seeds are alternately exposed to hot air, which prevents one side from being heated for a long time during the drying process, further reducing the risk of uneven drying.

[0017] 3. This low-temperature drying oven for crop seeds can quickly install and remove the filter plate through a limiting component. The filter plate can prevent impurities and foreign objects from entering the drying chamber, reducing contamination of the seeds and keeping the drying environment clean. During the low-temperature drying process, the filter plate can help improve air circulation, promote faster evaporation of moisture on the seed surface, and improve drying efficiency. The limiting component can ensure that the filter plate remains in a fixed position during operation, preventing the filter plate from shifting due to movement or vibration.
