Grain storage is a continuation of agricultural cultivation, and storage technology has developed along with the development of agriculture. my country is a major agricultural country. After entering the new era, with the development of agriculture, agricultural production has formed a certain scale, and there is more and more grain. The demand for granaries is increasing. How to effectively preserve the dryness of grain through ventilation has also become an important direction for granaries.

[0003] After searching, the Chinese patent with authorization announcement number CN221178539U discloses a ventilation device for granaries. This structure can ventilate the interior of the granary by setting a ventilation component to ensure the dryness of the grain inside the granary. At the same time, the filter can be disassembled and installed through the ventilation component, which is convenient for cleaning or replacing the filter. The sealing component can be used to seal the ventilation pipe when the ventilation component is not in use.

[0025] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, a flipping structure is provided at the bottom of the mounting plate 1, and the flipping structure includes a motor 4, which is fixedly mounted on the outer wall of the mounting plate 1, and a rotating rod 5 is fixedly mounted on the output end of the motor 4, and a plurality of outer cylinders 6 are fixedly distributed on the outside of the rotating rod 5, and an inner rod 7 is slidably mounted inside the plurality of outer cylinders 6, and a plurality of limiting holes 19 are provided on the surfaces of the outer cylinder 6 and the inner rod 7, and a limiting bolt 20 is installed on the internal thread of the limiting hole 19, and a material shovel 8 is detachably mounted on one end of the inner rod 7.

During the rotation, the digging shovel 8 will scoop up the grain inside the granary and rotate it to a high place, and then scatter it freely, thereby achieving a tumbling operation on the grain. During the scattering of the grain, the ventilation effect inside the grain can be improved, and the grain can be prevented from piling up inside the granary and affecting the internal ventilation effect.

[0027] At the same time, the inner rod 7 slides inside the outer cylinder 6, which can adjust the spacing between multiple material shovels 8, increase the turning range of grain inside the granary, and limit and tighten the adjusted inner rod 7 and outer cylinder 6 through the limiting bolt 20, thereby improving the stability of the outer cylinder 6 and the inner rod 7 during rotation.

[0028] In a specific embodiment, as shown in the attached Figure 4 、 5 As shown, the outer wall of the mounting plate 1 is provided with an embedding groove 9, the interior of the embedding groove 9 is provided with a mounting frame 10, the interior of the mounting frame 10 is provided with a dustproof net 11, the surface of the mounting frame 10 is provided with a pull groove 12, and the two inner walls of the embedding groove 9 are provided with T-shaped grooves 13. T-shaped blocks 14 are fixedly installed at both ends of the mounting frame 10, the T-shaped blocks 14 are adapted to the structure of the T-shaped groove 13, and the T-shaped blocks 14 are slidably connected inside the T-shaped groove 13.

[0029] Specifically, when the two ventilation fans 3 are used to ventilate the grain inside the granary, the dustproof net 11 can not only prevent external dust from entering the granary, but also prevent rats from entering.

[0030] Once the dust screen 11 is clogged or damaged, the operator can lift the installation frame 10 upwards by pulling the groove 12, so that the T-block 14 is disengaged from the inside of the T-slot 13, and then the installation frame 10 can be removed from the inside of the embedding groove 9, making it easier to clean and maintain the filter screen inside the installation frame 10;

[0031] Similarly, after the T-shaped block 14 is slid into the interior of the T-shaped slot 13 , the mounting frame 10 can be installed in the interior of the embedding slot 9 for use.

[0032] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, the outer portion of the rotating rod 5 is sleeved with a support tube 15 , and an L-shaped rod 16 is fixedly provided at the bottom of the support tube 15 .

[0034] In a specific embodiment, as shown in the attached Figure 3 As shown, a sleeve 17 is fixedly mounted on the surface of the digging shovel 8, the inner rod 7 is located inside the sleeve 17, and a fastening bolt 18 is provided between the inner rod 7 and the sleeve 17, and the fastening bolt 18 is used to detachably connect them.

[0035] Specifically, in this structure, the inner rod 7 and the sleeve 17 can be disassembled and assembled by fastening the bolts 18, which makes it convenient for the operator to disassemble and assemble the material shovel 8 and the inner rod 7, and to replace the damaged or worn material shovel 8, and different specifications of material shovels 8 can be installed.

[0036] Working principle of this utility model:

[0037] The present application provides a grain tumbling ventilation device for a granary. When in use, first, a mounting plate 1 is installed at a location in the granary where ventilation is required, and two ventilation fans 3 are used to rotate inside corresponding ventilation rings 2 to ventilate the grain inside the granary.

[0038] During ventilation, the motor 4 drives the rotating rod 5 to rotate, and drives the corresponding digging shovel 8 to rotate through the sleeve 17 and the inner rod 7. During the rotation, the digging shovel 8 will scoop up the grain inside the granary and rotate it to a high place, and then scatter it freely, so as to achieve the purpose of tumbling the grain. During the free scattering period, the contact area of ​​the grain with the ventilation environment 2 is maximized, thereby improving the ventilation effect inside the grain and preventing the grain from accumulating inside the granary and affecting the internal ventilation effect.

[0039] At the same time, during ventilation, the dustproof net 11 can not only prevent external dust from entering the interior of the granary, but also prevent mice from entering. Once the dustproof net 11 is blocked or damaged, the operator can lift the installation frame 10 upwards through the pull groove 12, so that the T-block 14 is detached from the inside of the T-slot 13, and then the installation frame 10 can be removed from the inside of the embedded groove 9, which is convenient for cleaning and maintenance of the filter inside the installation frame 10.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
