[0001] This utility model belongs to the field of grain drying, and specifically relates to a grain dryer that is easy to clean. Background Technology
[0002] A grain dryer is a device used to reduce the moisture content of grains to a level suitable for storage and transportation. Grains such as rice, wheat, corn, and soybeans typically need to be dried after harvesting to prevent mold, fermentation, or rot.
[0003] Traditional dryers have a relatively simple structure, which often leads to over-drying of some grains, resulting in waste. In addition, the traditional tank-turning structure has limited effect on turning the grains, and blind spots are easily created during actual use, making it difficult to reach the turning structure. Furthermore, in order to ensure the drying effect, existing dryers are often designed as an integrated unit. Such integrated dryers are difficult to clean after use, and dust or grain particles can easily remain inside the dryer, affecting its service life.
[0004] Therefore, in response to the problems of existing grain dryers being inconvenient to clean and having poor grain drying effects, a grain dryer that is easy to clean is developed. By adding a wind-assisted structure, a wind-cleaning structure, and a stirring and turning structure to the grain dryer, the drying effect and efficiency of traditional grain dryers can be effectively improved, and the ease of self-cleaning can be enhanced.

Detailed Implementation
[0023] A grain dryer is a device used to reduce the moisture content of grains to a suitable level for storage and transportation. Grains such as rice, wheat, corn, and soybeans typically need to be dried after harvest to prevent mold, fermentation, or rot. Grain dryers effectively control drying temperature and humidity to ensure drying quality while reducing energy waste.
[0024] Working principle of a grain dryer:
[0025] Hot air drying: The dryer heats air and blows it evenly into the grains, causing the moisture in the grains to evaporate. The air temperature and flow rate are adjustable to ensure uniform drying of the grains.

Different heat sources have different advantages and disadvantages in different applications. Moisture removal: Moisture generated during the drying process is removed, ensuring effective removal of moisture from the grains. Automatic control system: Modern grain dryers are usually equipped with an automatic control system that can control the temperature according to the set drying time and humidity, ensuring the stability and effectiveness of the drying process.
[0026] Types of grain dryers:
[0027] Fluidized bed dryer: Suitable for small, easily flowing grains. It works by using high-speed hot air to blow the grains into a fluidized state, thereby accelerating moisture evaporation. Rotary drum dryer: Grains are dried through rotating drums. It is suitable for large-scale drying needs, is highly efficient, and suitable for batch production. Belt dryer: Grains are conveyed by a conveyor belt and receive hot air evenly. It is suitable for continuous production. Batch dryer: Suitable for small-scale drying needs. It is usually operated in batches and is often used in small farms or experimental operations.
[0028] Advantages of grain dryers:
[0029] Energy efficient: Modern equipment adopts efficient heat exchange and intelligent control systems, which can maximize the utilization of heat energy and reduce energy consumption. Reduced loss: By scientifically controlling temperature and humidity, grain loss caused by overheating or uneven heating in traditional drying methods is avoided.

[0033] Please see Figures 1-6 The present invention provides an embodiment comprising a drying tank 3, a support platform 1, and a foot 7, as well as a drive motor 4, a blower 5, and stirring blades 6. The drying tank 3 is equipped with heating wires inside. A support plate 12 is installed at the upper opening of the drying tank 3. Through holes 13 are opened at both the upper and lower ends of the support plate 12. The drive motor 4 is installed at the upper end of the support plate 12. The output end of the drive motor 4 is fixedly connected to a drive shaft 15 through the through holes 13. Several sets of stirring blades 6 are fixedly connected to the outer wall of the drive shaft 15 at equal intervals. Stirring grooves 16 are opened on the stirring blades 6 and are evenly distributed around the stirring blades 6. The blower 5 is divided into two sets distributed on the left and right sides. The blower 5 is connected to the drying tank 3 through a pipe.
[0034] The drying tank 3, equipped with heating wires, can perform preliminary drying of the grains inside. Then, the drive motor 4 drives several sets of stirring blades 6 to stir and mix the grains in the drying tank 3, so that they are constantly tumbling in the drying tank 3, thereby improving the drying effect and efficiency of the drying tank 3. The blowers 5 distributed on the left and right can not only assist the heat in the drying tank 3 to circulate in the drying tank 3 with wind power during drying, but also use strong wind to clean the dust or particles in the drying tank 3 when cleaning is required.
[0035] Please see Figure 3 In this embodiment, feet 7 are fixedly connected to the four corner edges of the lower end of the support platform 1. The upper and lower ends of the support platform 1 are provided with first grooves 8. In use, the feet 7 and the support platform 1 can provide stable support for the drying tank 3, thereby improving the stability of the device in use. Arc rods 2 are fixedly connected to the four corner edges of the upper end of the support platform 1. A ring frame 9 is fixedly connected between the arc rods 2. In use, the arc rods 2 and the ring frame 9 can provide limiting support for the center of the outer wall of the drying tank 3, thereby improving the stability of the drying tank 3 in use.
[0036] Please see Figure 4In this embodiment, a feed hopper 10 is fixedly connected to the upper outer wall of the drying tank 3. A hinged cover 11 is hinged to the upper opening of the feed hopper 10. During use, the hinged cover 11 can be rotated and closed after feeding to prevent grain from splashing out of the feed hopper 10 during turning. A discharge pipe 14 is installed at the lower end of the drying tank 3. A valve is installed in the discharge pipe 14. During use, the valve on the discharge pipe 14 can control the grain to be discharged out of the discharge pipe 14 after drying. The lower outer wall of the drying tank 3 is fixedly connected to the first trough 8. The central outer wall of the drying tank 3 is fixedly connected to the annular frame 9. During use, the outer wall of the drying tank 3 can be limited at multiple points by the first trough 8 and the annular frame 9 to improve its stability during use.
[0037] Please see Figure 6 In this embodiment, the stirring blades 6 are distributed along the inner wall of the drying tank 3. Several sets of stirring blades 6 are distributed in a shape that is narrow at the top and bottom and wide in the middle. During use, the stirring blades 6, which are narrow at the top and bottom and wide in the middle, can fully stir and mix the grains in the drying tank 3 to prevent them from being overheated during the turning process.
[0038] Before use, turn the opening and closing cover 11 to open, then pour the grains to be dried into the feed hopper 10 so that the grains enter the drying tank 3, and then close the opening and closing cover 11.
[0039] During drying, the drive motor 4 is started first, which drives the drive shaft 15 and the stirring blades 6 on it to rotate at a uniform speed so that the grains in the drying tank 3 are turned over and stirred. Then the drying tank 3 is started, and the electric heating wire inside it heats and dries the grains that are turned over in the drying tank 3.
[0040] Next, start the two sets of blowers 5, which will deliver air to the drying tank 3 to assist in the circulation of heat inside, thereby efficiently drying the grains in the drying tank 3.
[0041] After drying is complete, activate the valve inside the discharge pipe 14 to open the discharge pipe 14 so that the dried grain can be discharged downwards.
[0042] When it is necessary to clean the drying tank 3, open the discharge pipe 14 and the opening and closing cover 11, and start the blower 5. The blower 5 will deliver strong air into the drying tank 3 to blow out the dust or particulate matter inside the drying tank 3 through the air force.
[0043] Through the above steps, the grains inside the drying tank 3, which is equipped with heating wires, can be initially dried. Then, the drive motor 4 drives several sets of stirring blades 6 to stir and mix the grains inside the drying tank 3, so that they are constantly tumbling inside the drying tank 3, thereby improving the drying effect and efficiency of the drying tank 3. The blowers 5 distributed on the left and right can not only help circulate the heat inside the drying tank 3 with air force during drying, but also use strong air force to clean the dust or particles inside the drying tank 3 when cleaning is needed. This solves the problems of existing grain dryers being inconvenient to clean and having poor grain drying effect.
[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
