Description

Technical Field

[0001] This utility model relates to the field of grain moisture-proof technology, specifically a moisture-proof preservation device for grain crop samples. Background Technology

[0002] In scientific research and quality inspection of grain crops, the proper preservation of grain crop samples is of paramount importance.

[0003] Through long-term work and market research, the inventors discovered that most common grain crop sample preservation devices currently rely on sealed structures for moisture prevention. However, this method has the following problems: although the sealed environment can isolate external moisture, it cannot handle the moisture generated by the respiration of the sample itself. Long-term storage can easily lead to increased internal humidity, causing mold and quality deterioration of the sample. To solve this problem, patent number CN202220028651.1 proposes a grain crop sample moisture-proof preservation device that effectively ensures airflow inside the device, making it easier to preserve the grain inside. Although the grain crop sample in this device can achieve air circulation, it only removes the moisture generated by respiration from the outer edges of the grain crop sample. The moisture generated by the respiration of the grain crop in the middle part cannot be removed in time due to the small air gaps between the grains, leading to mold and deterioration. It is difficult to meet the requirements of long-term, high-quality preservation of all grain crop samples.

[0004] To solve this problem, this utility model proposes a moisture-proof preservation device for grain crop samples. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a moisture-proof preservation device for grain crop samples.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A moisture-proof preservation device for grain crop samples includes:

[0008] The outer cylinder is preserved, and a cylindrical space is formed inside it;

[0009] The inner storage cylinder is coaxially arranged with the outer storage cylinder, and a drying space for drying the grain crops inside the inner storage cylinder is formed between the inner storage cylinder and the outer storage cylinder. Multiple ventilation holes communicating with the drying space are opened on the side wall of the inner storage cylinder.

[0010] The central shaft is vertically rotatably installed at the center of the bottom of the inner cylinder of the storage cylinder. A turning part is vertically slidably installed on its surface. Multiple turning holes that match the grain crop sample particles are opened at equal intervals on its side wall. The turning part on the side wall of the central shaft rotates around the inner wall of the storage cylinder and turns the grain crop sample in the storage cylinder through the turning holes, increasing the air circulation and ventilation gap between the sample particles.

[0011] Preferably, the inclined strip-shaped turning hole has a lower horizontal height at the front end than at the rear end in its rotation direction.

[0012] Preferably, a fixing block located below the turning part is fixedly installed on the side wall of the central shaft, and an elastic element is fixedly installed on the upper end face of the fixing block, with the upper end of the elastic element fixedly installed to the bottom of the turning part.

[0013] Preferably, a pin is fixedly installed on the bottom of the opposite side of the turning part, and the bottom of the pin is conical.

[0014] Preferably, the bottom surface of the storage outer cylinder is provided with multiple protrusions along the movement trajectory of the pin, and the top of the protrusions is arc-shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, as the grain sample particles pass through the strip hole, they will be driven to flow from the front end of the hole to the rear end of the hole, which increases the ventilation gap formed between the grain sample particles and the turning part. This is beneficial for the water vapor generated by the respiration of the middle part of the grain crop sample to be discharged in time through the ventilation gap, thus avoiding the grain crop sample from becoming moldy and deteriorating when stored for a long time, and meeting the needs of long-term, high-quality preservation of all grain crop samples.

[0017] 2. This utility model has a fixed block fixedly installed on the side wall of the central shaft, located below the turning part. An elastic element is fixedly installed on the upper end face of the fixed block. The upper end of the elastic element is fixedly installed to the bottom of the turning part. A pin is fixedly installed on the bottom of the turning part away from the center. The bottom of the pin is conical. Multiple protrusions are provided on the bottom surface of the outer cylinder along the movement trajectory of the pin. The top of the protrusions is arc-shaped. When the pin passes through multiple protrusions in sequence, it rises along the arc surface and then falls along the arc surface, causing the turning part to shake periodically, further expanding the ventilation gap, thereby increasing the dehumidification effect and meeting the requirements for long-term, high-quality preservation of all grain crop samples.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] Example

[0028] like Figures 1-6 As shown, a moisture-proof preservation device for grain crop samples includes:

[0029] The outer storage cylinder 4 has a cylindrical space inside, which is convenient for holding grain crop samples. The top of the outer storage cylinder 4 is equipped with a lid 5, which can prevent dust and moisture in the air from entering the outer storage cylinder 4.

[0030] The inner storage cylinder 10 is coaxially arranged with the outer storage cylinder 4. A drying space for the grain crop inside the inner storage cylinder 10 is formed between the inner storage cylinder 10 and the outer storage cylinder 4. Multiple ventilation holes 9 are provided on the side wall of the inner storage cylinder 10 to connect with the drying space. Each ventilation hole 9 is connected to the drying space. The ventilation holes 9 can promote the air circulation and exchange between the inner storage cylinder 10 and the outer storage cylinder 4, and remove the water vapor generated by the respiration of the grain crop sample.

[0031] The circulation pipe 6, with its two ends bent upwards at 90 degrees, passes through the bottom of the outer storage cylinder 4 and the gap to allow air to pass through. A dehumidification component is installed inside the circulation pipe 6 to remove moisture from the air inside the outer storage cylinder 4. The dehumidification component includes a dehumidifying filter element 15 and an air pump 14 located on both sides of the impeller 7. Both the dehumidifying filter element 15 and the air pump 14 are fixedly installed inside the circulation pipe 6 and are detachable from the circulation pipe 6. After the air pump 14 is started, the air inside the outer storage cylinder 4 enters through one end of the circulation pipe 6, passes through the dehumidifying filter element 15, the impeller 7 and the air pump 14, and is discharged back into the outer storage cylinder 4 through the other end of the circulation pipe 6. After the dehumidifying filter element removes moisture from the inside of the device, the air re-enters the device, ensuring that the air inside the device is dry and preventing the grain crop samples from becoming moldy and deteriorating. When the airflow passes through the impeller 7, it will drive the impeller 7 to rotate, which in turn drives the central shaft 11 to rotate.

[0032] The central shaft 11 is rotatably mounted on the axis of the inner storage cylinder 10 and is driven by an external power source. A turning part 12 that slides against the inner wall of the inner storage cylinder 10 is fixedly mounted on its surface. Multiple turning holes 13 that match the grain crop sample particles are opened at equal intervals on its side wall. The central shaft 11 is driven by a drive source, namely a fan wheel 7, which drives the turning part 12 to rotate around the inner wall of the inner storage cylinder 10. The grain crop sample inside the inner storage cylinder 10 is turned over through the turning holes 13. When the grain sample particles pass through the turning holes 13, an air gap is formed between the grain sample and the turning part 12. The air gap is connected to at least one air hole 9 on the inner storage cylinder 10, forming an air circulation channel.

[0033] The lower end of the central shaft 11 passes through the outer storage cylinder 4 and the circulation pipe 6 and is fixedly installed with a fan 7. When the fan 7 rotates, it drives the turning part 12 on the side wall of the central shaft 11 to rotate around the inner wall of the inner storage cylinder 10. The turning part 13 turns the grain crop sample in the inner storage cylinder 10, increasing the ventilation gap between the grain sample particles and the turning part 12. This allows the water vapor generated by the respiration of the middle part of the grain crop sample to be discharged in time through the ventilation gap, avoiding the grain crop sample from becoming moldy and deteriorating when stored for a long time, and meeting the requirements of long-term, high-quality preservation of all grain crop samples.

[0034] In one embodiment, a bearing 8 is fixedly installed between the outer cylinder 4 and the base 1, and the central shaft 11 is fixedly inserted in the inner ring of the bearing 8. The bearing 8 reduces the friction when the central shaft 11 rotates, thus avoiding excessive heat and wear caused by friction.

[0035] In one embodiment, the turning hole 13 is an inclined strip hole, with the horizontal height of the front end of the hole being lower than that of the rear end in the direction of rotation. When the grain sample particles pass through the strip hole, they will be driven to flow from the front end to the rear end of the hole, thus turning the particles over and increasing the ventilation gap. This facilitates the timely removal of water vapor generated by the respiration of the grain particles, meeting the requirements for long-term, high-quality preservation of all grain crop samples.

[0036] In one embodiment, a controller 3 is fixedly installed on the side wall of the outer storage cylinder 4. Its signal receiving end is electrically connected to a humidity sensor, which is embedded in the inner wall of the outer storage cylinder 4. Its signal transmitting end is electrically connected to the air pump 14. When the humidity sensor detects that the humidity inside the device exceeds the critical value, the controller 3 will control the air pump 14 to start working, extracting and drying the air inside the device before discharging it back into the device.

[0037] In one embodiment, a base 1 is fixedly installed at the bottom of the outer storage cylinder 4 to prevent the outer storage cylinder 4 from contacting the ground and absorbing moisture from the ground.

[0038] In one embodiment, a fixing block 19 located below the turning section 12 is fixedly installed on the side wall of the central shaft 11. An elastic element 18 is fixedly installed on the upper end face of the fixing block 19. The upper end of the elastic element 18 is fixedly installed with the bottom of the turning section 12. A pin 17 is fixedly installed on the bottom side of the turning section 12 away from 11. The bottom of the pin 17 is conical. Multiple protrusions 20 are provided on the bottom end face of the storage outer cylinder 4 along the movement trajectory of the pin 17. The top of the protrusions 20 is arc-shaped. When the pin 17 passes through the multiple protrusions 20 in sequence, it rises along the arc surface of the protrusions 20 and then falls along the protrusions 20, causing the turning section 12 to shake periodically, further expanding the ventilation gap and thus increasing the dehumidification effect.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
