Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

In the description of the utility model, unless otherwise specified, the meaning of "a plurality of", "several" is two or more than two, unless otherwise explicitly limited.

[0045] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0046] As shown in Figure 1 、 Figure 2 The utility model discloses a filter and impurity removal device for silage machine radiator, is installed in the air inlet side of silage machine radiator, and the filter and impurity removal device includes frame 100, filter screen subassembly 200, drive subassembly 300, impurity removal cover 400 and dust absorption subassembly 500. The frame 100 is installed on the air inlet side of the radiator, and the frame 100 is provided with air inlet 101, and the air inlet 101 is communicated with the air inlet side of the radiator. Filter screen subassembly 200 is rotatably installed in air inlet 101. Drive subassembly 300 is used to drive filter screen subassembly 200 to rotate in air inlet 101. Impurity removal cover 400 is installed on the air inlet side of frame 100, and impurity removal cover 400 shields part of filter screen subassembly 200, and the side of impurity removal cover 400 towards filter screen subassembly 200 is open to form opening 401, and the other side is provided with suction interface 410.

[0047] Dust absorption subassembly 500 is connected to suction interface 410, wherein dust absorption subassembly 500 includes dust suction pipe 510 and dust suction fan 520, dust suction pipe 510 is connected between dust suction fan 520 and dust suction interface, and dust suction fan 520 operates to form negative pressure in impurity removal cover 400.

[0048] During the operation of the silage machine, the radiator continuously dissipates heat through the external air, and the external air enters the radiator from the air inlet side of the radiator. Since the air inlet side of the radiator is provided with the filtering and impurity removing device, the filtering and impurity removing device filters the dust and impurities in the air. During the operation of the radiator, the driving assembly 300 rotates at a low speed, so that the filter screen assembly 200 rotates at a low speed while filtering the dust and impurities. When the rotating filter screen assembly 200 passes through the impurity removing cover 400, the dust and impurities on the filter screen assembly 200 are sucked away from the opening 401 in the impurity removing cover 400 by the negative pressure in the impurity removing cover 400, so that the filter screen assembly 200 is kept clean, and the accumulation of dust and impurities on the filter screen assembly 200 is avoided to affect the air inlet efficiency of the filter screen assembly 200.

[0049] The filtering and impurity removing device of the utility model, through the filter screen assembly 200 driven to rotate by the driving assembly 300 and the cooperation of the filter screen assembly 200 and the dust suction assembly 500 and the shielding of the filter screen assembly 200 by the impurity removing cover 400, the dust and impurities filtered on the filter screen assembly 200 can be continuously sucked away by the cooperation of the impurity removing cover 400 and the dust suction assembly 500, so that the filter screen assembly 200 is kept clean, the accumulation of dust and impurities on the filter screen assembly 200 is avoided, and the good air inlet efficiency of the filter screen assembly 200 is ensured.

[0050] In one embodiment, the filtering and impurity removing device based on the foregoing embodiments, as shown in Figure 4 、 Figure 5 The filter screen assembly 200 includes an outer frame 210 and a filter screen 220 installed in the outer frame 210. The air inlet 101 is circular, and the outer frame 210 is adapted to the shape of the air inlet 101. Since the outer frame 210 does not rotate with the filter screen assembly 200, by setting the air inlet 101 and the outer frame 210 of the filter screen assembly 200 to be circular, the interference between the filter screen assembly 200 and the frame 100 can be avoided, and the filtering area of the filter screen assembly 200 can be maximized.

[0051] Since the filter screen assembly 200 rotates relative to the frame 100, a rotating gap is provided between the filter screen assembly 200 and the air inlet 101 of the frame 100. In order to prevent dust and impurities from entering the radiator through the rotating gap, in this embodiment, the air inlet 101 is circumferentially provided with a brush extending towards the filter screen assembly 200. By isolating dust and impurities from entering the radiator through the rotating gap between the filter screen assembly 200 and the air inlet 101, the amount of dust and impurities entering the radiator is reduced.

[0052] In one embodiment, the filtering and impurity removing device based on the foregoing embodiments, as shown in Figure 2 、 Figure 4 、 Figure 5As shown, multiple filters 220 are provided, and multiple filters 220 are detachably installed in the outer frame 210. Due to the working environment of the silage machine, the dust and debris filtered by the filters 220 contain a lot of moisture. Some dust and debris that are difficult to be sucked away by negative pressure will accumulate on the filters 220, and the operator needs to disassemble these filters 220 individually for cleaning.

[0053] By setting multiple filters 220 and detachably installing them in the outer frame 210, it is convenient for operators to remove, replace and clean individual filters 220 individually. Operators do not need to remove the entire filter assembly 200 during operation. At the same time, the filtration and impurity removal device can continue to work after replacing several filters 220, thereby speeding up the maintenance time of the filtration and impurity removal device and improving maintenance efficiency.

[0054] In one embodiment, the filtration and impurity removal device based on the foregoing embodiments, such as Figure 2 , Figure 3 As shown, the drive assembly 300 includes a drive belt 320 and a drive motor 310. The outer frame 210 has a belt groove 211 circumferentially arranged on its outer side to mate with the drive belt 320. The drive assembly 300 also includes a drive wheel 311, which is mounted on the drive motor 310. The drive belt 320 is tensioned in the belt groove 211 and the drive wheel 311. The operation of the drive motor 310 drives the drive wheel 311 to rotate, and the rotation of the drive wheel 311 drives the outer frame 210 to rotate via the drive belt 320, thereby causing the filter assembly 200 to rotate.

[0055] In one embodiment, the filtration and impurity removal device based on the foregoing embodiments, such as Figure 2 , Figure 3 As shown, the drive assembly 300 also includes a tensioning mechanism 330, which includes a tensioning wheel 331, a fixed support, a rotating arm 333, and an adjusting rod 334. The fixed support is fixed to the frame 100, the rotating arm 333 is rotatably connected to the frame 100, one end of the adjusting rod 334 is rotatably connected to the rotating arm 333, and the other end is screwed to the fixed bracket 332. The tensioning wheel 331 is rotatably connected to the end of the rotating arm 333 away from the adjusting rod 334.

[0056] The tension pulley 331 is pressed against the drive belt 320. By rotating the adjusting rod 334, the rotating arm 333 is rotated, thereby adjusting the force of the tension pulley 331 pressing against the drive belt 320, and thus adjusting the tension of the drive belt 320. A suitable tension of the drive belt 320 is beneficial to the transmission efficiency between the drive motor 310 and the filter assembly 200.

[0057] With the above settings, the tension of the drive belt 320 can be adjusted, so that the filter assembly 200 can rotate well with the operation of the drive motor 310, avoiding poor transmission effect between the filter assembly 200 and the drive motor 310, and improving the reliability of the filtration and impurity removal device.

[0058] In one embodiment, the filtration and impurity removal device based on the foregoing embodiments, such as Figure 1 , Figure 2 , Figure 4 As shown, the impurity removal hood 400 extends from the rotation axis of the filter assembly 200 toward the frame 100.

[0059] Specifically, the frame 100 includes a frame body 110 and a support frame 120. An air inlet 101 is located in the frame body 110, and the support frame 120 is located on the air outlet side of the frame body 110. A dust removal hood 400 is located on the air inlet side of the frame body 110. A rotating shaft is located in the center of the support frame 120. A filter assembly 200 is rotatably mounted on the rotating shaft. The rotation axis of the filter assembly 200 is concentric with the rotating shaft. One end of the dust removal hood 400 is connected to the rotating shaft, and the other end of the dust removal hood 400 extends towards the frame 100 and is connected to the frame 100.

[0060] With this configuration, the dust collector hood can have a large coverage area in the radial direction of the filter assembly 200, so that when the filter assembly 200 rotates, a large area can pass through the negative pressure area of ​​the dust collector hood, thereby improving the impurity removal efficiency of the filtration and impurity removal device and maintaining the air intake efficiency of the filter assembly 200.

[0061] In some other embodiments, the rotating shaft may also be disposed on the filter assembly 200, which is rotatably connected to the support frame 120 via the rotating shaft, and one end of the impurity removal cover 400 is connected to the rotating shaft.

[0062] In this embodiment, the support frame 120 is arranged in a cross shape. In some other embodiments, the central support frame 120 may also be in a "Y" shape, "X" shape, or the like. This structure of the support frame 120 can enhance its strength, allowing the support frame 120 to remain stable when the filter assembly 200 rotates, and also keeping the dust collection hood stable.

[0063] With this configuration, the dust hood 400 can have a larger coverage area in the radial direction of the filter assembly 200, so that when the filter assembly 200 rotates, a larger area can pass through the negative pressure area of ​​the dust hood 400, thereby improving the impurity removal efficiency of the filtration and impurity removal device and maintaining the air intake efficiency of the filter assembly 200.

[0064] In one embodiment, the filtration and impurity removal device based on the foregoing embodiments, such as Figure 1 , Figure 2 , Figure 4As shown, the dust removal hood 400 extends downwards from the frame 100, and the dust suction port 410 is located at the lower end of the dust removal hood 400. In this way, on the one hand, the dust suction pipe 510 connected to the dust suction port 410 avoids the central area of ​​the filter assembly 200, thereby preventing the dust suction pipe 510 from blocking the air intake side of the filter assembly 200 and affecting the air intake efficiency of the filter assembly 200. On the other hand, after the dust and debris on the filter assembly 200 are sucked away by negative pressure, they are more easily sucked away by the dust suction assembly 500 under the combined action of negative pressure and gravity, reducing the escape of dust and debris from the filter assembly 200 and improving the dust removal efficiency.

[0065] In one embodiment, the filtration and impurity removal device based on the foregoing embodiments, such as Figure 5 As shown, a baffle plate 130 is provided on the air outlet side of the frame 100, and the baffle plate 130 is positioned opposite the opening 401 of the impurity removal hood 400. The baffle plate 130 is positioned opposite the opening 401 of the impurity removal hood 400, creating a negative pressure area between the impurity removal hood 400 and the baffle plate 130. The impurity removal hood 400 is located on the air inlet side of the frame 100, and the baffle plate 130 is located on the air outlet side of the frame 100. This allows the filter assembly 200 passing through the impurity removal hood 400 and the baffle plate 130 to be in the negative pressure area, improving the impurity removal effect on the filter assembly 200 within the negative pressure area.

[0066] The above-mentioned setup creates a negative pressure zone between the impurity removal hood 400 and the baffle plate 130, improving the impurity removal effect of the filter assembly 200 passing through the negative pressure zone, thereby enhancing the impurity removal effect of the filtration and impurity removal device.

[0067] Understandably, the optimal effect is achieved when the size of the baffle 130 and the opening 401 of the impurity removal hood 400 are roughly the same. If the baffle 130 is too small, it reduces the area of ​​the negative pressure zone; if the baffle 130 is too large, it blocks the air intake area of ​​the filter assembly 200, affecting the air intake effect.

[0068] In one embodiment, the filtration and impurity removal device based on the foregoing embodiment includes a scraper in the impurity removal hood 400, with one end of the scraper contacting the filter assembly 200. The scraper is used to scrape off dust and debris from the filter assembly 200, and the scraped dust and debris are sucked away by the suction assembly 500 under negative pressure. The scraper can directly contact the filter screen 220 of the filter assembly 200, for example, a flexible scraper can be used. Alternatively, flexible scraper strips or brushes can be installed on the scraper, and the filter screen 220 of the filter assembly 200 can be contacted through the flexible scraper strips or brushes.

[0069] In this embodiment, the length of the scraper extends along the extension direction of the impurity removal cover 400, thereby increasing the contact area between the scraper and the filter assembly 220.

[0070] In some other embodiments, the contact area between the scrapers and the filter assembly 220 is increased by arranging multiple scrapers along the extension direction of the impurity removal hood 400.

[0071] By installing a scraper in the impurity removal hood 400, the scraper can scrape off dust and debris from the filter assembly 220. The scraped-off dust and debris can be sucked away by the negative pressure of the dust collection assembly 500, thereby improving the impurity removal efficiency of the filtration and impurity removal device. At the same time, the length of the scraper extends along the extension direction of the impurity removal hood 400, or multiple scrapers are arranged along the extension direction of the impurity removal hood 400, which increases the contact area between the scraper and the filter assembly 200, further improving the impurity removal efficiency of the filtration and impurity removal device.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
