Description

Technical Field

[0001] The utility model relates to the technical field of grain bin ventilation equipment, in particular to an intelligent grain bin ventilation device. Background Art

[0002] A grain bin, that is, a special building for storing grain, is used to store a large amount of grain. Since a large amount of grain is stored inside, in order to prevent the occurrence of grain dampness and mildew caused by poor internal air circulation, a grain bin ventilation device is required.

[0003] The prior art has the following deficiencies: In the "Intelligent Grain Bin Ventilation Device" with the publication number of CN205389564U in the prior art, "it includes a ventilation duct communicated with the inner cavity of the grain bin, a nitrogen generator, a grain cooler, a grain conditioning ventilator, a phosphine generator and a phosphine tail gas processor communicated between the inlet and outlet sections of the ventilation duct, a grain moisture detector, a grain temperature sensor, a nitrogen concentration detector and a phosphine concentration detector installed in the inner cavity of the grain bin and connected to the input end of the control device, an outdoor temperature and humidity sensor and a rain sensor installed outside the grain bin and connected to the input end of the control device; the nitrogen generator, the grain cooler, the grain conditioning ventilator, the phosphine generator and the phosphine tail gas processor are connected to the control end of the control device; valves are installed at the inlets and outlets of the nitrogen generator, the grain cooler, the grain conditioning ventilator, the phosphine generator and the phosphine tail gas processor".

[0004] The above structure performs automatic detection through the cooperation of structures such as a nitrogen generator, a grain cooler, a grain conditioning ventilator, a phosphine generator and a phosphine tail gas processor. However, the internal pipeline structure of this equipment does not make any treatment for dust adhesion. Since there is a large amount of grain stored in the grain bin, a large amount of dust is generated during the process of grain transportation, transfer and taking. Although the dust can be discharged through the ventilation duct, some dust will adhere and accumulate on the inner wall of the ventilation duct. After a long time of dust accumulation, due to long-term drying, it will form a hard shell, and a new round of dust accumulation will be established on its surface, which not only affects the cleanliness of the inside of the ventilation duct, but also makes it difficult to maintain and clean the inside of the ventilation duct. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an intelligent grain bin ventilation device, which solves the problem of dust adhesion and crust formation inside the ventilation duct that exists nowadays.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An intelligent ventilation device for a granary, comprising a ventilation pipe, a mounting ring, a front support frame, and a fan. The mounting ring is connected to the front end of the ventilation pipe. The front support frame penetrates through the interior of the front end of the ventilation pipe. The fan is disposed at the front end of the front support frame. A front motor is connected to the rear end of the fan. A connecting column extending outward is fixedly connected to the outer peripheral end face of the front motor. The end of the connecting column is fixedly connected to the inner wall end face of the ventilation pipe;

[0007] A middle shaft is disposed behind the front motor. A rear support frame is disposed on one side of the rear end of the middle shaft. A dust sensor mechanism is further disposed at the front end of the mounting ring;

[0008] The middle shaft further includes a rotating scraper, a plastic scraping head, and a rear motor. One end of the rotating scraper close to the middle shaft is in a tubular structure and is sleeved on the outer peripheral end face of the middle shaft through the tubular structure. The plastic scraping head is fixedly connected to the outer end of the rotating scraper. The rear motor is movably connected to the rear end of the middle shaft.

[0009] As a preferred technical solution of the present utility model, the front end of the middle shaft is connected to the rear side of the front motor, and a shaft seat structure is provided at the connection. The rear end of the middle shaft extends through the rear support frame, and a bearing structure is provided at the connection with the rear motor.

[0010] As a preferred technical solution of the present utility model, four tooth groove structures are provided inside the outer end of the plastic scraping head.

[0011] As a preferred technical solution of the present utility model, both the front support frame and the rear support frame are internally hollow structures and vertically penetrate through the front and rear ends of the ventilation pipe.

[0012] As a preferred technical solution of the present utility model, the number of the rotating scrapers can be customized and adjusted. The specific number is positively correlated with the length of the front section of the ventilation pipe. The lengths of the rotating scraper and the plastic scraping head need to refer to the specific dimensions of the ventilation pipe. After the plastic scraping head is installed, it needs to just touch the inner wall of the ventilation pipe.

[0013] As a preferred technical solution of the present utility model, the dust sensor mechanism needs to be connected to an external display control device for signal transmission, and the front motor and the rear motor also need to be connected to an external control structure for use.

[0014] As a preferred technical solution of the present utility model, the rotating scraper itself is in a rectangular structure, and the two corners facing the inner wall of the ventilation pipe are rounded, and the inside is provided with a hollowed-out treatment with a rectangular inner rounded corner.

[0015] Compared with the prior art, the present utility model provides an intelligent ventilation device for a granary, having the following

[0016] Beneficial effects:

[0017] For a kind of intelligent ventilation device for granaries, by setting up a dust sensor mechanism, a middle shaft, a rotating scraper and a plastic scraper head, when the device is installed and the granary ventilation operation is carried out, the operator turns on the front motor, the rear motor and the dust sensor mechanism through the externally connected control device and conducts real-time monitoring. During normal ventilation operation, the operator only needs to turn on the front motor to drive the fan to rotate to promote air circulation and achieve the ventilation purpose. When transferring grain inside the granary or changing the position of the grain, a large amount of dust is generated. The dust floats up and is discharged from the granary through the ventilation pipe. Some dust may adhere to the inner wall of the pipe when passing through the ventilation pipe. When the dust sensor mechanism at the front end of the device senses that the dust density in the air is relatively high, it sends a signal to the control mechanism, and the operator turns on the rear motor. The rear motor drives the middle shaft to rotate, and the middle shaft drives the rotating scraper and the plastic scraper head to rotate. Multiple groups of plastic scraper heads scrape the inner wall of the pipe, causing the dust adhering to the inner wall of the pipe to gather and fall, and finally being discharged from the ventilation pipe along with the air flow;

[0018] Through the above process, the device can have the following beneficial effects:

[0019] Through the cooperation of multiple groups of rotating scrapers and plastic scraper heads, the dust adhering to the inner wall of the pipe for a short time can be quickly gathered at the front end of the plastic scraper head and finally fall off. Through the perception of the dust sensor mechanism, when the dust density is high, the inner wall of the pipe will be cleaned, so that the time for the dust to adhere to the inner wall of the pipe will not be too long, and it will be removed before the dust forms a hard shell state, ensuring the cleanliness of the inner wall of the ventilation pipe and facilitating the later maintenance and regular cleaning of the inside of the ventilation pipe.

[0026] Please refer to Figures 1-4 , in this implementation: An intelligent ventilation device for a granary includes a ventilation pipe 1, a mounting ring 2, a front support frame 3, and a fan 5. The mounting ring 2 is connected to the front end of the ventilation pipe 1. The mounting ring 2 bears the installation of the dust sensor mechanism 4. The front support frame 3 penetrates through the interior of the front end of the ventilation pipe 1. The front support frame 3 supports the front motor 6.

[0027] A middle shaft 8 is arranged behind the front motor 6. The middle shaft 8 bears the installation of the rotating scraper 801. A rear support frame 9 is arranged on one side of the rear end of the middle shaft 8. The rear support frame 9 supports the rear motor 803 and the middle shaft 8. A dust sensor mechanism 4 is also arranged at the front end of the mounting ring 2. The dust sensor mechanism 4 detects the dust density and sends information to an external control structure;

[0028] The middle shaft 8 further includes a rotating scraper 801, a plastic scraper head 802, and a rear motor 803. One end of the rotating scraper 801 close to the middle shaft 8 is in a tubular structure and is sleeved on the outer peripheral end face of the middle shaft 8 through this tubular structure. The plastic scraper head 802 is fixedly connected to the outer end of the rotating scraper 801. The rear motor 803 is movably connected to the rear end of the middle shaft 8.

The rear end of the middle shaft 8 extends through the rear support frame 9, and a bearing structure is arranged at the connection with the rear motor 803; Four tooth groove structures are formed inside the outer end of the plastic scraper head 802;

[0030] It should be noted that: when the rotating scraper 801 drives the plastic scraper head 802 to scrape the inner wall of the pipeline, the end of the plastic scraper head 802 closely adheres to the inner wall of the pipeline, and the four groups of tooth-shaped grooves increase the friction force when rubbing against the inner wall of the pipeline, forcing the dust to be completely scraped off;

[0031] In this embodiment, both the front support frame 3 and the rear support frame 9 have a hollow structure inside and vertically penetrate through the front and rear ends of the ventilation pipe 1; the number of the rotating scrapers 801 can be customized and adjusted, and the specific number is positively correlated with the length of the front section of the ventilation pipe 1. Moreover, the lengths of the rotating scrapers 801 and the plastic scraping heads 802 need to refer to the specific size of the ventilation pipe 1, and the plastic scraping heads 802 need to just touch the inner wall of the ventilation pipe 1 after installation;

[0032] Specifically, the position where dust accumulates in the ventilation pipe 1 is usually in the front section of the ventilation pipe 1. Therefore, different numbers of rotating scrapers 801 can be set according to the length of the front section of the ventilation pipe 1 to ensure sufficient cleaning efficiency while saving costs for equipment investment;

[0033] In this embodiment, the dust sensor mechanism 4 needs to be connected to an external display control device for signal transmission, and the front motor 6 and the rear motor 803 also need to be connected to an external control structure for use; the rotating scraper 801 itself is in a rectangular structure, and the two corners facing the inner wall of the ventilation pipe 1 are rounded, and the inside is made of a hollowed-out treatment with a rectangular inner fillet.

[0034] The working principle and usage process of the present utility model: When the equipment is installed and the ventilation operation of the granary is carried out, the operator turns on the front motor 6, the rear motor 803, and the dust sensor mechanism 4 through the externally connected control device and monitors them in real time. During normal ventilation operation, the operator only needs to turn on the front motor 6 to drive the fan 5 to rotate to promote air circulation and achieve the ventilation purpose. When transporting grain inside the granary or changing the position of the grain, a large amount of dust is generated. The dust floats up and is discharged from the granary through the ventilation pipe 1. Some dust may adhere to the inner wall of the pipe when passing through the ventilation pipe 1. When the dust sensor mechanism 4 at the front end of the equipment senses that the dust density in the air is relatively high, it sends a signal to the control mechanism, and the operator turns on the rear motor 803. The rear motor 803 drives the middle shaft 8 to rotate, and the middle shaft 8 drives the rotating scrapers 801 and the plastic scraping heads 802 to rotate. The multiple plastic scraping heads 802 scrape the inner wall of the pipe, causing the dust adhering to the inner wall of the pipe to gather and fall, and finally being discharged from the ventilation pipe 1 along with the airflow.
