Description

Technical Field

[0001] The present invention relates to the technical field of grain storage and drying, and in particular to a grain storage and drying device. Background Art

[0002] In the grain production and storage industry chain, drying grain in the sun is a critical pretreatment step for ensuring grain quality. Freshly harvested grain has a high moisture content. Direct storage can easily lead to mold and sprouting due to microbial growth. This not only causes grain loss but can also produce harmful substances such as aflatoxins, threatening food security. Therefore, reducing grain moisture content to safe storage standards (typically 12%-14%) through drying is an essential step before grain storage. Currently, traditional methods of drying grain in rural areas and small and medium-sized grain depots in my country still predominate. This involves manually spreading grain out in open areas (such as drying yards and courtyards) and allowing moisture to evaporate through natural light and ventilation.

[0003] Traditional manual drying relies mainly on manual labor using tools such as wooden rakes and brooms to spread and turn the grain, which has the following significant problems:

[0004] 1. Poor drying uniformity: Manual operation makes it difficult to ensure uniform grain thickness, which can easily lead to localized accumulation or thin areas. Pile-up areas are poorly ventilated, resulting in slow evaporation of moisture and a tendency for grain to mold. Thin areas can also deteriorate due to excessive exposure to the sun.

[0005] 2. High labor intensity and low efficiency: For example, harvesting approximately 500 kilograms of wheat from one acre of land requires two to three people to work together for several hours, and frequent turning is required to ensure uniformity, which is time-consuming and labor-intensive. For large-scale growers or grain depots, labor costs are extremely high. Summary of the Invention

[0033] The following is combined with Figure 1-7 The present invention is described in further detail.

[0034] The embodiment of the present invention discloses a grain storage drying device. Figure 1-7 , a grain storage drying device, comprising a bottom frame 1;

[0039] The driving assembly includes a bidirectional screw 25 and two movable plates 26. A movable groove 23 connected to the two slide grooves 21 is provided inside the support platform 4. Two movable plates 26 are slidably installed inside the movable groove 23. The movable plate 26 is fixedly installed between the corresponding two sliders 24. The bidirectional screw 25 is rotatably installed inside the movable groove 23. The bidirectional screw 25 passes through the two movable plates 26 and is threadedly connected to them. A turntable 22 is provided on one side of the support platform 4. The turntable 22 is connected to the bidirectional screw 25 through a limiting assembly. The thread between the bidirectional screw 25 and the movable plate 26 can achieve self-locking. The thread self-locking condition depends on the spiral angle of the thread, the friction coefficient and the load it is subjected to. The thread self-locking condition can be calculated by the following formula: Self-locking condition = friction coefficient × tan (spiral angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above contents are all existing technologies, and in actual applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here.

A spreading roller 13 is fixedly sleeved on the side wall of the two connecting shafts 28 for spreading grain.

[0044] A protective shell 16 is provided on the side walls of the two fixing plates 12 via a fixing assembly. A drive motor 27 for driving the installation shaft 30 to rotate is fixedly installed on the inner side wall of one of the protective shells 16. The installation shaft 30 is connected to the two connecting shafts 28 via a transmission assembly. The transmission assembly is provided inside the other protective shell 16.

[0045] The fixing assembly includes two mounting plates 38, which are symmetrically fixed to the side walls of the protective shell 16. The side walls of the two mounting plates 38 are threaded with fixing bolts 20 for fixing them to the fixing plate 12;

[0046] The transmission assembly includes multiple synchronous wheels 31. One end of the mounting shaft 30 and the connecting shaft 28 are movable through the side wall of one of the fixed plates 12, and a synchronous wheel 31 is fixedly sleeved thereon. Two adjacent synchronous wheels 31 are connected by a synchronous belt 32.

[0047] An armrest 5 is fixedly mounted on one side of the bottom frame 1, and two rubber sleeves 6 are fixedly sleeved on the side walls of the armrest 5;

[0048] A placement plate 10 is fixedly mounted on the left side of the upper surface of the support platform 4. A plurality of placement slots 11 are evenly arranged on the upper surface of the placement plate 10 for placing agricultural tools.

[0049] A solar panel 7, a controller 8 and a battery 9 are fixedly installed on the right side of the upper surface of the support platform 4 from front to back. The solar panel 7, the battery 9 and the drive motor 27 are all electrically connected to the controller 8 to realize intelligent control of the equipment.

[0050] The working principle of a grain storage drying device according to an embodiment of the present invention is as follows: During use, all electrical components in the present invention are connected to an external power source and control switch. The grain storage drying device is supported by a base frame 1 and is flexibly moved by running wheels 2. A solar panel 7, a controller 8, and a battery 9 above a support platform 4 form an energy supply system, powering a drive motor 27 and cooperating with the mechanical structure to complete the grain distribution and drying operations. During use, the device is first pushed to the grain storage area using handrails 5. Solar panels 7 absorb solar energy and convert it into electrical energy, which is processed by controller 8 and stored in battery 9. Battery 9 provides stable power for drive motor 27. Drive motor 27 is activated, driving mounting shaft 30 to rotate. Mounting shaft 30, via a transmission assembly (synchronous pulley 31 and synchronous belt 32), drives two connecting shafts 28 to rotate synchronously. Connecting shaft 28 rotates the tanning roller 13 mounted thereon. Mounting shaft 30, in turn, drives roller shaft 29 and the tanning plate 15 mounted thereon. The tanning plate 15 and tanning roller 13 work in conjunction with each other. The spreading plate 15 first breaks up and spreads the accumulated grain, and then the drying roller 13 further spreads the grain evenly, realizing continuous operation from centralized stacking to even drying. If the height of drying needs to be adjusted, the wheel 22 can be rotated to adjust the position of the slider 24 in the slide 21 through the drive assembly. Pulling the wheel 22 can drive the connecting rod 37 to move, so that the second magnetic piece 36 on the connecting rod 37 is away from the first magnetic piece 35. At the same time, the limit block 34 on the connecting rod 37 can slide in the limit groove 33. Then, rotating the wheel 22 can drive the connecting cylinder 17 to rotate through the limit block 34. The connecting cylinder 17 can drive the two-way screw 25 to rotate, so that the movable plate 26 drives the slider 24 to slide along the movable groove 23. The slider 24 can drive the first connecting seat 18 thereon to move. The first connecting seat 18 can be connected to the connecting plate 14 and the second connecting seat 19 drives the fixed plate 12 to move vertically, which in turn drives the distributing plate 15 and tanning roller 13 mounted thereon to change their operating range. When the distributing plate 15 and tanning roller 13 are adjusted to the appropriate height, the rotating wheel 22 drives the connecting rod 37 to move and reset, allowing the second magnetic plate 36 to align with the first magnetic plate 35. The magnetic forces of the first and second magnetic plates 35, 36, and the self-locking action of the bidirectional screw 25 and movable plate 26 ensure the height stability of the distributing plate 15 and tanning roller 13. The protective housing 16 is secured to the fixed plate 12 via a fixing assembly (mounting plate 38 and fixing bolts 20), protecting the internal motor and transmission components from dust and collisions. Raising the fixed plate 12 to a certain height facilitates subsequent installation or removal of the protective housing 16. During operation, the placement slot 11 on the placement plate 10 can temporarily store farm tools such as rakes and brooms, making it convenient for operators to sort out missed grains at any time; the armrest 5 wrapped with the rubber sleeve 6 improves the comfort when pushing the device and reduces operator fatigue.

[0051] During this process, the coordinated design of the spreading plate 15 and the drying roller 13 first breaks up the accumulated grain and then evenly spreads it out, solving the problem of uneven grain thickness in traditional manual drying. This ensures that the grain is more evenly exposed to light and ventilated, and the evaporation rate is consistent, effectively reducing the risk of localized mildew or excessive exposure, and improving the quality of drying. The coordination of the drive assembly and the connecting assembly allows for flexible adjustment of the drying height to accommodate the drying needs of different types of grain, such as wheat, corn, and rice. The operating range can also be adjusted according to the size of the site, making it highly versatile.

[0052] Here, the models of the controller 8 and the drive motor 27 can be optimized according to actual conditions. They are existing technologies and are widely used in society, so they will not be described in detail.
