Description
Technical Field
[0001] This utility model relates to the field of hot air box technology, specifically a hot air drying box. Background Technology
[0002] Soil drying using a hot air drying oven is a common laboratory technique used to remove moisture from soil samples for subsequent chemical analysis or other experiments. When a soil sample is placed in the hot air drying oven, the heat from the hot air is transferred to the soil sample, causing moisture evaporation. The hot air drying oven provides a stable supply of hot air to evaporate the moisture from the soil sample, thus drying it. This method is generally fast and effective in removing moisture from soil samples. However, careful control of the drying temperature and time is necessary during operation to avoid damaging the sample. However, existing methods for drying soil in hot air drying ovens often result in uneven drying, with some soil drying while others remain undried, affecting subsequent experimental analysis. Therefore, those skilled in the art have developed a hot air drying oven to address the problems mentioned in the background section. Utility Model Content
[0003] The purpose of this invention is to provide a hot air drying oven to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solutions:
[0005] A hot air drying oven includes a main body. A fixed base is fixedly connected to the bottom wall of the inner end of the main body. A support block is fixedly connected to one side of the upper end of the fixed base. A servo motor is fixedly connected to the upper end of the support block. Four sets of sliding rods are fixedly connected to the other side of the upper end of the fixed base. A vibrating plate is slidably connected to the outer side of the four sets of sliding rods. A roller is rotatably connected to the lower end of the vibrating plate. Springs are fixedly connected to the lower sides of both ends of the vibrating plate.
[0006] Preferably, the other end of the spring is fixedly connected to a fixed base, the output end of the servo motor is fixedly connected to a rotating rod, the rotating rod is rotatably connected to a rotating rod fixing bracket near both ends of the rotating rod, a cam is fixedly connected to the middle of the rotating rod, a connecting rod is fixedly connected to the upper end of the vibrating plate, a soil placement box is fixedly connected to the upper end of the connecting rod, a fixing rod is fixedly connected to both ends of the soil placement box, and a fixing rod movable groove is opened on both sides of the inner wall of the hot air drying box body on the outside of the fixing rod.
[0007] Preferably, a movable cover is hinged to the upper end of the hot air drying oven body, a temperature detector is fixedly connected to one end of the hot air drying oven body, a data screen is fixedly connected to the side of the upper end of the hot air drying oven body away from the temperature detector, an adjustment knob is fixedly connected to the side of the upper end of the hot air drying oven body near the data screen, and a switch is fixedly connected to the side of the upper end of the hot air drying oven body near the adjustment knob.
[0008] Preferably, a lower fixing member is fixedly connected to the other end of the hot air drying oven body, an upper fixing member is fixedly connected to the end of the movable cover near the lower fixing member, a bolt is threaded to the inner end of the upper fixing member, a rotating cover is fixedly connected to the upper end of the bolt, and a movable door handle is fixedly connected to the upper end of the movable cover near the upper fixing member.
[0009] Compared with the prior art, the beneficial effects of the present invention are:
[0010] 1. The servo motor rotates, driving the rotating rod to rotate, which in turn drives the cam to rotate. The cam then drives the roller to rotate, causing the vibrating plate to move up and down. Springs at both ends of the vibrating plate are fixed to the base, ensuring close contact between the cam at the lower end of the vibrating plate and the roller. The vibrating plate slides up and down on the sliding rod, causing the connecting rod to vibrate up and down. The connecting rod then vibrates the soil placement box up and down. The fixed rods at both ends of the soil placement box move within their movable slots. During operation in the hot air drying chamber, the soil placement box vibrates and tumbles. This up-and-down vibration and tumbling allows the soil to continuously change position within the chamber, resulting in more uniform heating, improved drying efficiency, and shorter drying time. This ensures more consistent drying speed and effect. The vibration and tumbling also increase contact and friction between soil particles, improving heat transfer efficiency and accelerating the evaporation of moisture from the soil. Furthermore, the up-and-down vibration and tumbling effectively prevents soil accumulation and clumping within the box, ensuring more uniform heating during the drying process.
[0011] 2. When soil drying is required, first rotate the rotating cover. The rotating cover will cause the bolts to rotate, loosening the upper and lower fixing parts. Then, open the movable cover using the handle. The switch controls the power supply of the hot air drying oven, and the adjustment knob adjusts the temperature and time. The data screen will display important parameters such as the current internal temperature and time of the hot air drying oven. Operators can monitor the temperature to ensure that the drying process is carried out within a suitable temperature range to avoid damage to the sample or affecting the analysis results due to excessively high temperatures. The temperature detector is responsible for real-time monitoring of the internal temperature of the hot air drying oven, which is crucial to ensuring that the drying process is carried out within an appropriate temperature range. By continuously monitoring the temperature, operators can promptly detect temperature abnormalities or fluctuations and take corresponding measures to adjust the temperature, ensuring that the sample is not damaged by excessively high or low temperatures. Place the soil into the soil placement box, close the movable cover using the handle, and then rotate the rotating cover. The rotating cover will cause the bolts to rotate, tightening the lower and upper fixing parts to prevent the hot air drying oven from opening during operation. The fixed base secures the vibrating body. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the movable cover 16 is fixedly connected to a movable door handle 25 close to the upper fixing piece 22.
[0018] The working principle of this utility model is as follows: When soil drying is required, first rotate the rotating cover. The rotating cover drives the bolts to rotate, loosening the upper and lower fixing parts. Then, open the movable cover using the movable door handle. The switch controls the power supply of the hot air drying oven, and the adjustment knob adjusts the temperature and time of the hot air drying oven. The data screen displays important parameters such as the current internal temperature and time of the hot air drying oven. Operators can monitor the temperature to ensure that the drying process is carried out within a suitable temperature range, avoiding damage to the sample or affecting the analysis results due to excessively high temperatures. The temperature detector is responsible for real-time monitoring of the internal temperature of the hot air drying oven, which is crucial to ensuring that the drying process is carried out within an appropriate temperature range. By continuously monitoring the temperature, operators can promptly detect temperature abnormalities or fluctuations and take corresponding measures to adjust the temperature, ensuring that the sample is not damaged by excessively high or low temperatures. Place the soil into the soil placement box, close the movable cover using the movable door handle, and then rotate the rotating cover. The rotating cover drives the bolts to rotate, and the bolts tighten the lower and upper fixing parts, preventing the hot air drying oven from opening during operation. The fixed base secures the vibrating body. Turning on the switch activates the servo motor, which in turn drives a rotating rod. This rotating rod, in turn, drives a cam, which in turn drives a roller. The cam then causes the vibrating plate to move up and down. Springs at both ends of the vibrating plate are fixed to the fixed base, ensuring close contact between the cam at the lower end of the vibrating plate and the roller. The vibrating plate slides up and down on a sliding rod, causing the connecting rod to vibrate up and down. The connecting rod, in turn, causes the soil placement box to vibrate up and down. The fixed rods at both ends of the soil placement box move within their movable slots. During operation in the hot air drying chamber, the soil placement box vibrates and tumbles. This up-and-down vibration and tumbling allows the soil to continuously change position within the chamber, resulting in more even heating, improved drying efficiency, and shorter drying time. This ensures more consistent drying speed and effect. The vibration and tumbling also increase contact and friction between soil particles, improving heat transfer efficiency and accelerating the evaporation of moisture from the soil. Furthermore, the up-and-down vibration and tumbling effectively prevents soil accumulation and clumping within the box, ensuring more even heating during the drying process.
