In existing grain storage ventilation equipment, dust cannot be effectively collected, causing dust to re-adhere to the filter plate after cleaning, thus affecting the filtration effect.
A scraping assembly and a squeezing transmission assembly are installed inside the ventilation housing. The scraping assembly cleans the surface of the filter plate, and the squeezing transmission assembly causes the dust to enter the collection box during the scraping process. After resetting, the shielding assembly automatically shields the dust, thus achieving timely collection of the dust.
This effectively reduces the amount of dust that re-adheres to the filter plate after cleaning, improves the filtration effect, and ensures the continuous and efficient operation of the ventilation equipment.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ventilation equipment, specifically, it relates to a grain storage ventilation equipment. Background Technology
[0002] Grain silos, specialized buildings for storing large quantities of grain, are crucial for preventing mold and rot and ensuring grain quality. Maintaining a dry and well-ventilated environment is essential for safe storage and quality assurance. Therefore, ventilation is indispensable. When selecting ventilation systems, factors such as energy consumption, ventilation efficiency, control precision, and environmental friendliness must be considered to ensure the system meets practical needs and is sustainable.
[0003] Chinese utility model patent CN221948797U discloses a ventilation device for grain storage, including a ventilation duct, a support frame fixedly installed inside the ventilation duct, a ventilation fan rotatably installed on the support frame, a drive motor fixedly installed at the top of the ventilation duct, a rotating rod fixedly installed on one side of the drive motor, and a transmission belt connecting the rotating rod and the ventilation fan. A dustproof plate is fixedly installed on one side of the ventilation duct. Although this device, by setting up a cleaning scraper and threaded rod, can simultaneously drive the ventilation fan and the cleaning scraper to automatically clean the surface of the dustproof plate, thereby improving the ventilation effect, in actual use, when the scraper cleans the surface of the dustproof plate, the dust on the dustproof plate is scraped off. If the dust cannot be collected, the dust scraped off inside the duct will re-adhere to the dustproof plate, affecting the filtration effect.
[0004] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings.
[0027] Please see Figure 1-6 As shown, this embodiment provides a grain storage ventilation and air exchange device, including: an air exchange shell 1, an air inlet hood 2 and an air outlet pipe 3 respectively provided on both sides of the air exchange shell 1, a fan provided in the air outlet pipe 3, and a filter plate 8 provided in the air exchange shell 1. When the fan is started, it can ventilate the grain silo.
[0028] A placement groove 9 is provided on one side of the ventilation housing 1, and a collection box 6 is provided in the placement groove 9. A scraping component corresponding to the filter plate 8 is installed on one side of the inner wall of the ventilation housing 1. A blocking component 12 corresponding to the collection box 6 is installed at the opening of the placement groove 9. A pressing transmission component 14 corresponding to the scraping component is installed inside one side of the ventilation housing 1. The pressing transmission component 14 cooperates with the blocking component 12.
[0029] The scraping assembly installed inside the ventilation housing 1 can scrape the surface of the filter plate 8 from top to bottom, making it easier to clean the dust adhering to the surface of the filter plate 8. The extrusion transmission assembly 14 installed inside the ventilation housing 1 can drive the shielding assembly 12 to remove the shielding of the collection box 6 during the downward scraping process of the scraping assembly, so that the scraped dust falls into the collection box 6. After the scraping assembly returns to its upward position, the shielding assembly 12 automatically shields the collection box 6, which can collect and shield the dust in time, thereby reducing the possibility of the cleaned dust re-adhering to the filter plate 8 and affecting the filtration effect.
[0030] like Figure 3-4 As shown, the scraping assembly of this embodiment includes a scraper 10 that is slidably fitted on one side of the inner wall of the ventilation housing 1 and corresponds to the filter plate 8, a linear drive 11 that is installed on one side of the inner wall of the ventilation housing 1 and connected to the scraper 10, and a compression transmission assembly 14 that corresponds to the scraper 10; the linear drive 11 includes a linear motor or a slide rail.
[0031] like Figure 4-6 As shown, the shielding assembly 12 in this embodiment includes a fixing groove 1201 formed on one side of the placement groove 9, a shielding plate 1203 slidably fitted in the fixing groove 1201 and corresponding to the top of the collection box 6, and a plurality of springs 1202 installed between the shielding plate 1203 and the fixing groove 1201. The extrusion transmission assembly 14 cooperates with the shielding plate 1203. An installation groove 13 communicating with the fixing groove 1201 is formed on one side of the inner wall of the ventilation housing 1. The extrusion transmission assembly 14 includes a cylinder 1401 installed in the installation groove 13, a sliding... The cylinder 1401 is equipped with a first piston 1402 and a second piston 1403, a connecting rod 1404 fixedly connected to the baffle plate 1203 on one side of the first piston 1402, and a pressing rod 1405 installed on the upper side of the second piston 1403 and corresponding to the scraper 10. The cylinder 1401 has an L-shaped structure. The gas in the cylinder 1401 is sealed by the first piston 1402 and the second piston 1403. The first piston 1402 can compress the second piston 1403 and move it in the cylinder 1401.
[0032] When cleaning the dust adhering to the filter plate 8, the linear drive 11 drives the scraper 10 to move downward to scrape the dust adhering to the plate 8. During the downward movement of the scraper 10, the extrusion rod 1405 is squeezed and moved. The movement of the extrusion rod 1405 drives the second piston 140 to move. The second piston 1403 moves downward in the cylinder 1401 and squeezes the first piston 1402 to move through the atmosphere. The first piston 1402 moves horizontally in the cylinder 1401 and drives the connecting rod 1404 to move. The movement of the connecting rod 1404 drives the baffle plate 1203 to move and retract into the fixing groove 1201. The baffle plate 1203 retracts into the fixing groove 1201 and removes the obstruction of the collection box 6, so that the scraped dust can fall into the collection box 6 for collection.
[0033] When the linear drive 11 drives the scraper 10 to reset upward, the scraper 10 releases its pressure on the squeezing rod 1405. The baffle 1203 automatically blocks the top of the collection box 6 through the elastic force of multiple springs 1202, which can promptly collect and block the dust, thereby reducing the situation where dust re-adheres on the filter plate 8 after cleaning and affects the filtration effect. The linear drive 11 can be a linear motor or a slide rail.
[0034] like Figure 1-3 As shown, a groove 7 is provided on one side of the ventilation housing 1 in this embodiment, and the filter plate 8 is located in the groove 7. A mounting plate 4 located on one side of the ventilation housing 1 is installed on the side of the filter plate 8. A plurality of screws 5 are provided on the mounting plate 4 that are threadedly engaged with the ventilation housing 1. The plurality of screws 5 can detach the mounting plate 4 from the ventilation housing 1, thereby facilitating the removal and replacement of the filter plate 8 from the groove 7.
