Description

Technical Field

[0001] This utility model belongs to the technical field of grain dryers, specifically relating to a grain dryer based on the Internet of Things. Background Technology

[0002] Grain drying technology is a key link in the modern agricultural production chain. Its development is closely related to the process of agricultural mechanization. Early grain drying mainly relied on natural sun drying, which was significantly constrained by climate conditions and was inefficient. With the advancement of industrialization, mechanical drying equipment gradually became popular, and large-scale processing was achieved through technologies such as hot air circulation and fluidized bed. However, traditional equipment generally adopts independent control systems and relies on local manual operation.

[0003] Currently, the mainstream grain dryers on the market are still mainly based on single-machine control, lacking information interaction capabilities between devices. Due to the lack of integrated IoT modules, it is impossible to realize real-time collection and remote transmission of equipment operating parameters. Managers need to check the data on the instrument panel on-site, making it difficult to centrally monitor multiple devices. This offline state leads to production scheduling delays. For example, it is impossible to dynamically adjust drying parameters according to weather changes, which can easily cause energy waste or a decline in grain quality.

[0004] Therefore, for the existing grain dryers mentioned above, which cannot be remotely connected to the network and cannot be remotely and automatically controlled for drying, resulting in difficulties in remote production monitoring and low production efficiency, an Internet of Things-based grain dryer can be designed. Utility Model Content

[0005] To overcome the problems of existing grain dryers, which cannot be remotely networked and cannot be remotely automated to control the drying process, resulting in difficulties in remote production monitoring and low production efficiency.

[0006] The technical solution of this utility model is as follows: a grain dryer based on the Internet of Things, including a drying component, a feeding component, an air duct component, a blower, and a network controller; the feeding component is arranged on the upper side of one side of the drying component; the air duct component is arranged at the lower end of the drying component; a blower is arranged at one end of the air duct component; the network controller is arranged at the rear of the air duct component; the drying component includes a drying chamber, a lower exhaust pipe, a temperature and humidity sensor, a high-temperature resistant breathable mesh plate, and an alarm; the air duct component includes a heating air duct and an electric heating wire.

[0007] Preferably, the temperature and humidity inside the lower drain pipe are monitored in real time by a temperature and humidity sensor to determine the grain drying status. In conjunction with a network controller, the blower speed, the feed speed of the drive motor, and the temperature of the air heated by the heating wire are automatically controlled. This comprehensively adjusts the drying rate of the grain on the high-temperature resistant and breathable mesh plate, improving the convenience of drying adjustment. This solves the problem of existing grain dryers, which cannot be remotely networked and cannot be remotely automated to control the drying process, resulting in high difficulty in remote production monitoring and low production efficiency.

[0008] Preferably, a lower drain pipe is provided on one side of the drying chamber, and the interior of the lower drain pipe is connected to the drying chamber; a high-temperature resistant and breathable mesh plate is provided at the lower end of the drying chamber; a temperature and humidity sensor is provided inside the lower drain pipe; and an alarm is provided above the temperature and humidity sensor.

[0009] Preferably, the feeding assembly includes a feeding bin, a feeding screw, a reducer, and a drive motor; the feeding bin is located on one side of the drying chamber.

[0010] Preferably, a drive motor is installed at the rear end of the feeding hopper; a reducer is installed at one end of the drive motor; and a feeding screw is installed on one side of the reducer.

[0011] Preferably, the upper port of the feeding screw tube is connected to the lower port of the unloading hopper, and the output port of the feeding screw tube is connected to the interior of the drying chamber.

[0012] Preferably, a heating air duct is provided at the lower end of the drying chamber, and one end of the heating air duct is connected to the lower port of the drying chamber.

[0013] Preferably, the heating duct is equipped with an electric heating wire inside.

[0014] Preferably, a blower is provided at one end of the heating air duct, and the output end of the blower is connected to the heating air duct. The network controller is connected to the temperature and humidity sensor for information transmission, and the network controller controls the blower, heating air duct, and drive motor.

[0015] The beneficial effects of this utility model are:

[0016] 1. Existing grain dryers suffer from low production efficiency and difficulty in remote monitoring due to their inability to be remotely networked and automated. This new system uses temperature and humidity sensors to monitor the internal temperature and humidity of the lower drying pipes in real time, thereby determining the grain drying status. A network controller automatically adjusts the blower speed, the drive motor's feeding speed, and the temperature of the air heated by the heating wires. This comprehensive adjustment of the drying rate of the grain on the high-temperature resistant and breathable mesh plate improves the ease of drying control. This solution addresses the problem of low production efficiency and difficulty in remote monitoring caused by the inability to remotely network and automate the drying process in existing grain dryers.

[0017] 2. Through the setup of drying components, feeding components, air duct components, and blowers, grains are first fed into the feeding hopper. The drive motor drives the reducer to rotate the screw inside the feeding screw tube, thus pushing the grains falling into the feeding screw tube into the drying hopper. The grains falling into the drying hopper stay on the high-temperature resistant and breathable mesh plate. At this time, the blower blows air heated by the heating wire into the drying hopper along the heating air duct. The hot air heats and dries the grains, and the evaporated water vapor is discharged from the upper port of the drying hopper with the airflow. Because the internal moisture of the grains evaporates after drying, their weight is reduced, and the upward airflow blows the dried grains into the feeding hopper to complete the collection function. At this time, in conjunction with the temperature and humidity sensor, the network controller automatically controls the blowing speed of the blower, the feeding speed of the drive motor, and the temperature of the air heated by the heating wire in real time.

[0026] Please see Figure 1-5 In this embodiment, a lower drain pipe 102 is provided on one side of the drying chamber 101, and the interior of the lower drain pipe 102 is connected to the drying chamber 101; a high-temperature resistant and breathable mesh plate 104 is provided at the lower end of the drying chamber 101; a temperature and humidity sensor 103 is provided inside the lower drain pipe 102; an alarm 105 is provided above the temperature and humidity sensor 103; the feeding assembly 2 includes a feeding bin 201, a feeding screw 202, a reducer 203, and a drive motor 204; a feeding bin 201 is provided on one side of the drying chamber 101; a drive motor 204 is provided at the rear end of the feeding bin 201; a reducer 203 is provided at one end of the drive motor 204; a feeding screw 204 is provided on one side of the reducer 203. The feeding screw tube 202 is configured to connect the upper port of the feeding hopper 201 to the lower port of the feeding hopper 201, and the output port of the feeding screw tube 202 is configured to connect to the interior of the drying chamber 101; a heating air duct 301 is configured at the lower end of the drying chamber 101, and one end of the heating air duct 301 is configured to connect to the lower port of the drying chamber 101; an electric heating wire 302 is configured inside the heating air duct 301; a blower 4 is configured at one end of the heating air duct 301, and the output end of the blower 4 is configured to connect to the heating air duct 301; a network controller 5 is connected to the temperature and humidity sensor 103 for information transmission, and the network controller 5 controls the blower 4, the heating air duct 301, and the drive motor 204.

[0027] During operation, grains are first fed into the feeding hopper 201. The drive motor 204 drives the reducer 203 to rotate the screw in the feeding screw tube 202, thus pushing the grains falling into the feeding screw tube 202 into the drying hopper 101. The grains falling into the drying hopper 101 stay on the high-temperature resistant and breathable mesh plate 104. At this time, the blower 4 blows the air heated by the heating wire 302 into the drying hopper 101 along the heating air pipe 301. The hot air heats and dries the grains and discharges the evaporated water vapor from the upper port of the drying hopper 101 with the airflow. Since the internal moisture of the grains evaporates after drying, its weight is reduced, and the upward airflow blows the dried grains into the feeding hopper 201 to complete the collection function.

[0028] Next, the temperature and humidity inside the lower drain pipe 102 are monitored in real time by the temperature and humidity sensor 103 to determine the grain drying status.

This solves the problem of existing grain dryers, which cannot be remotely networked and cannot be remotely automated to control the drying process, resulting in high difficulty in remote production monitoring and low production efficiency.

[0029] Through the above steps, the temperature and humidity inside the lower pipe 102 are monitored in real time by the temperature and humidity sensor 103 to determine the grain drying status. In conjunction with the network controller 5, the blowing speed of the blower 4, the feeding speed of the drive motor 204, and the temperature of the air heated by the heating wire 302 are automatically controlled. This comprehensively adjusts the drying rate of the grain on the high-temperature resistant and breathable mesh plate 104, improving the convenience of drying adjustment. This avoids the problems of existing grain dryers, which cannot be remotely networked and cannot be remotely automated to control the drying process, resulting in high difficulty in remote production monitoring and low production efficiency.
