Description

Technical Field

[0001] This patent relates to the technical field of grain processing equipment, specifically an automatic grain drying device suitable for small and medium-sized farms or farmers, and particularly an automated device for grain spreading, turning, and rapid collection based on environmental monitoring and mechanical linkage. Background Art

[0002] Current grain drying is an essential link in agricultural production. Traditional drying methods rely on manual spreading, turning, and collection, resulting in low efficiency and being restricted by weather conditions. In the prior art, some mechanized drying equipment has been applied, but there are still the following problems:

[0003] Low degree of automation: For example, the "Grain Turning and Drying Device" disclosed in Patent CN201620178376.6 requires manual operation for grain turning and drying and cannot respond to changes in environmental temperature and humidity in real time.

[0004] Insufficient collection efficiency: The "Grain Turning and Drying Mechanism and Device" disclosed in Patent CN202322463050.0 adopts a fixed structure and cannot quickly collect grains in case of sudden rain, leading to the risk of mildew.

[0005] Poor protection ability: Most existing devices are designed for open-air collection and are difficult to adapt to quickly collecting grains and keeping them dry in the face of approaching rainy days, resulting in grains getting damp and moldy.

[0006] Based on the above background, this patent aims to provide a grain drying device integrating environmental monitoring, automatic turning, and rapid collection functions to solve the problems of insufficient automation, low collection efficiency, and poor protection ability in the prior art. Summary of the Invention

[0007] In order to overcome the defects in the prior art that existing drying equipment relies on manual intervention, cannot protect the dryness of grains, lacks a rapid collection mechanism, and has poor ability to cope with sudden weather, this patent provides a new structure to solve the related problems of grain drying.

[0008] The technical solution adopted by the present invention to solve its technical problems is: an automatic drying device for grains, including a grain gathering device, a grain conveying device, a grain storage device, and a grain turning and drying device; the gathering device includes: a propeller plate rotating column: it is placed on the inner walls of both sides of the support plate, and the inner walls of the through holes opened on the surfaces of the two support plates are movably connected to this rotating column; the grain conveying device includes: a rotating grain conveying crawler: this crawler has a grain hanging belt, which can turn up the grain, and is placed on the inner wall of the grain conveying channel. After the propeller plate rotating column gathers the grain, it conveys the grain to the storage box through the rotating grain conveying crawler; a grain conveying rain cover: the grain conveying channel is sealed on all sides and used as a rain cover; the grain storage device includes: a grain storage box: an inner warehouse with a larger capacity, provided with a rain cover; the grain turning and drying device includes: a grain turning and drying board: when turning and drying is required, the turning and drying board is lowered to turn and sieve the grain on the ground for drying.

[0009] The above-mentioned automatic drying device for grains, the propeller plate rotating column is a cylindrical axis with propellers in opposite directions on the left and right sides respectively, which can gather the grains on the ground where the collecting device passes to the middle, and the propeller plate rotating column is placed on the inner walls on both sides of the support plate. The inner walls of the through holes opened on the surfaces of the two support plates are movably connected to the rotating column, and the rotating column is connected to an electric motor. When the device is working, the motor starts to rotate and drives the rotation of the propeller plate, thereby realizing the collection and gathering of the grains spread on the ground.

[0010] The aforementioned automatic grain drying device features a rotating grain conveyor belt with an angled grain-hanging belt, i.e., an extension that can carry the gathered grain. To ensure the belt's proper rotation, motors are built into each end of the belt. The motors drive the belt, and the movement of the belt with the grain-hanging belt transfers the gathered grain to a storage bin. To prevent the gathered grain from being blown away by wind or affected by rain, the grain conveyor is covered with a rain cover, providing both wind and moisture protection.

[0011] The above-mentioned automatic drying device for grains, the grain storage device is a large storage space for holding the grains collected by the grain conveying device, and in order to prevent the wind from blowing the grains away and the rain from causing the grains to become wet, a rain cover is also added to the storage bin, which can effectively alleviate the impact of the external environment. At the same time, in order to cope with emergency rainy weather, there is also an emergency drying mode, which can dry the gas in the storage bin to ensure that the grains are kept as dry as possible.

[0012] The above-mentioned automatic grain drying device, the grain turning and drying device is a plow-shaped plate that can be freely controlled to unfold and close. When it is necessary to turn and dry the grain on the ground, the plow-shaped plate is lowered. At this time, when the device moves freely in the grain drying factory, the lowered plow-shaped plate can be used to scrape and turn the grain to complete the turning and drying of the grain.

[0013] The automatic grain drying device of this patent realizes the full automation of the grain drying process by integrating gathering, conveying, storing and turning and drying modules, combining closed-loop temperature and humidity monitoring with mechanical linkage. The device can automatically adjust the turning and drying frequency to ensure drying uniformity. It has a built-in quick folding mechanism that can complete the grain storage in the warehouse within 5 minutes in case of sudden weather, and adopts a rain-proof cover and an emergency drying mode to cope with the risk of rain. Its modular design supports multi-crop adaptation, operates with low energy consumption and is convenient to maintain. At the same time, it supports remote data monitoring, effectively solving the problems of traditional drying relying on manual labor, low efficiency and poor risk resistance, and is suitable for large-scale agricultural scenarios.

Detailed Description of the Invention

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the following further details the present invention in conjunction with specific examples.

[0019] See Figure 1, note that the direction with the storage box 4 is the positive direction. The propeller shaft 17 is fixed to the outer wall of the top of the bottom plate 24. The inner walls of the through holes opened on the surfaces of the two support plates 22 are both movably connected to the propeller shaft 17, and the propeller plates 2 are welded between the propeller shafts 17. During normal operation, the rotation of the motor drives the second gear 12 to rotate. Under the rotation of the second gear 12, the transmission belt 13 is driven to move. Through the transmission effect, the propeller shaft 17 also starts to rotate. Since the welding directions of the propeller plates on the left and right sides of the propeller shaft 17 are opposite, the grains can be gathered to the middle position under the rotation of the propeller shaft 17. At the same time, the grain baffle 1 can also play a role in gathering the grains on the ground. When this device passes over the ground where the grains are dried, the grain baffle 1 can retain the grains, making it more convenient for the propeller plate 2 to collect the grains.

[0020] See Figure 2 , a grain conveyor rain cover 3 has a grain conveyor belt shaft 14 fixed to the inner top. There is also a shaft in the middle of the propeller shaft 17. The grain conveyor belt 15 is wound around the two shafts. The rotation of the propeller shaft 17 can drive the rotation of the grain conveyor belt 15. There are hanging grain belts 16 on the surface of the grain conveyor belt 15, evenly distributed on the surface of the grain conveyor belt 15. As Figure 2 shown, the included angle between the hanging grain belt 16 and the grain conveyor belt 15 is an acute angle, which can store grains more effectively. Through the rotation of the grain conveyor belt 15, the gathered grains can be collected by the hanging grain belt 16 and then transported to the storage box 4, thus realizing the collection and transportation of grains.

[0021] See Figure 2 , the ploughing grain plate 5 can be adjusted in direction to meet the working requirements at different angles. One end of it is connected to the third gear 23 and fixed by the gear fixer 18. The third gear 23 meshes with the first gear 9. The center of the first gear 9 is connected to the motor shaft. Through the rotation of the motor, the first gear 9 rotates, and the rotation of the first gear 9 drives the rotation of the third gear 23. Thus, the movement of the ploughing grain plate 5 can be driven, so the ground angle of the ploughing grain plate 5 can be adjusted to meet different working requirements.

[0021] See Figure 2 and Figure 3There is a lifting hydraulic rod 6 under the storage box 4, which can be used to lift the storage box 4, and the grain in the storage box 4 can also be unloaded. The design of the lifting hydraulic rod 6 is convenient for loading and unloading grains. At the same time, there is a grain placing plate 20 at the rear of the storage box 4, the upper part of which is made into an axis shape, and there are two raised shaft grooves on both sides of the rear of the storage box 4. The upper shaft of the grain placing plate 20 is placed in the shaft groove, thereby realizing the free rotation of the grain placing plate 20. At the same time, in order to prevent the grain from flowing out, a grain-stopping rod 19 is also designed. The lower end of the grain-stopping rod 19 is connected to a motor, and the rotation of the motor drives the rotation of the grain-stopping rod 19. When unloading the grain, the grain-stopping rod 19 is lifted to allow the grain to flow out. When the grain is not unloaded, the grain-stopping rod 19 is lowered to press against the grain placing plate 20, thereby effectively preventing the grain from flowing out.
