For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0041] Reference will be made below Figures 1-13 The dust suction device according to the utility model embodiment is described, which is used for dust suction operation of the receiving hopper of the color sorter. When the color sorter screens the material, the rejection mechanism changes the path of the material into the waste bin 41 by blowing, the dust blown up is dispersed in the space in the middle of the sorting chamber, the sorting chamber is the screening space, and is attached to the glass of the sorting chamber, causing more dust at the recognition device 2, and reducing the recognition accuracy of the recognition device 2. The dust suction device is connected to one side of the recognition device 2, the dust suction inlet of the dust suction device faces the waste bin 41, and is used for sucking the dust in the waste bin 41, thereby reducing the dust falling into the recognition device, improving the recognition accuracy of the recognition device 2, and simultaneously, at least the inner surface of the device body 5 of the dust suction device is a smooth surface, thereby reducing the possibility of dust accumulation of the device body 5, and facilitating cleaning of the dust suction cavity by setting the selectively opened cleaning port.

[0042] As Figures 1-13 shown, the dust suction device according to one embodiment of the utility model is used for connecting the waste bin 41 of the color sorter, and is located at one side of the recognition device of the color sorter, and comprises a device body 5.

[0043] The device body 5 is provided with a hollow dust suction cavity, and at least the inner surface of the dust suction cavity is a smooth surface in cross section; the device body 5 is provided with a dust suction inlet 512 facing the waste bin 41, so that the dust in the waste bin 41 enters the device body 5 through the dust suction inlet 512, and the device body 5 is provided with a cleaning port 511 which is selectively opened.

[0044] In addition, the identification device 2 is mainly used to identify whether the material is qualified according to color, and when identifying, the material needs to be photographed to determine whether the material meets the qualified requirements. When the material is identified as waste by the identification device, the material is rejected towards the waste bin 41, and the dust on the material in the waste bin 41 and the dust inside the waste bin 41 are blown up and fall on the identification device 2, which reduces the clarity of the photograph of the identification device 2 due to the dust, thereby affecting the accuracy of the material screening.

[0045] As shown in Figure 1 The device body 5 is installed on the left upper part of the waste bin 41, and the device body 5 is connected with the identification device 2 through a connecting frame 514. The device body 5 is also provided with a dust suction inlet 512 facing the waste bin 41, and the dust or impurities enter the device body 5 through the dust suction inlet 512, and the dust is sucked away by the device body 5, thereby reducing the dust adhered to the identification device 2. Specifically, as shown in Figure 1 The identification device 2 is arranged on the upper side of the device body 5, and the device body 5 first absorbs the dust on the lower side of the identification device 2, thereby preventing the dust from flying upwards and affecting the identification device 2.

[0046] At least the inner surface of the dust suction cavity of the device body 5 is a smooth surface in cross section, thereby reducing the probability of dust accumulation. In addition, the device body 5 is also provided with a cleaning port 511. When the device body 5 normally absorbs the dust, the cleaning port 511 is closed. When there is too much dust and impurities in the device body 5, the dust and impurities in the dust suction cavity can be cleaned through the cleaning port 511, thereby ensuring efficient dust absorption.

[0047] Therefore, the device body 5 is arranged at the identification device 2, thereby improving the accuracy of the identification device 2 in identifying the material, reducing the probability of dust accumulation of the dust suction device, and facilitating the cleaning of the dust suction cavity through the selectively opened cleaning port, thereby improving the efficiency of dust absorption.

[0048] In some embodiments, the device body 5 is connected with a dust suction door cover 52 at the cleaning port 511 through a locking member. The locking member can be selectively locked or loosened, and when loosened, the dust suction door cover 52 can be rotated outward to open the cleaning port 511 or separated from the cleaning port 511 to open.

[0049] In practice, the cleaning port 511 is provided with a dust suction door cover 52, which is provided with a handle 521. When the handle 521 is pulled to open the dust suction door cover 52, the inside of the device body 5 can be cleaned to ensure smooth and efficient dust suction. When the locking member locks the dust suction door cover 52, the dust suction door cover 52 is fixedly connected at the cleaning port 511. When the locking member is released, the dust suction door cover 52 can be rotated outward. For example, the dust suction door cover 52 is rotatably connected at the cleaning port 511. When the dust suction door cover 52 is closed, the dust suction door cover 52 is locked by the locking member to prevent rotation, thereby improving the stability of the connection between the dust suction door cover 52 and the cleaning port 511 and preventing the dust suction door cover 52 from rotating due to excessive pressure during dust suction. That is, the cleaning port 511 can be opened by partially disassembling the dust suction door cover 52 to improve the convenience of operation. When actually operated, the dust suction door cover 52 can be completely opened as needed.

[0050] Further, the cleaning port 511 can be arranged at the middle of the device body 5. In this way, the distance between the cleaning port 511 and other positions inside the device body 5 is not too far, and each position inside the device body 5 can be easily reached through the cleaning port 511 to clean the blockage. Of course, when the length of the device body 5 is sufficient, multiple cleaning ports 511 can be arranged at intervals on the device body 5.

[0051] In some embodiments, the cleaning port 511 is provided with a locking member on each side along the length direction of the device body 5, and the dust suction door cover 52 is provided with a clamping groove 551 that is open downward. The locking member locks the dust suction door cover 52 at the clamping groove 551.

[0052] Referring to Figure 2As shown, the locking member is a bolt, and the clamping groove 551 at the dust suction door cover 52 is open towards the lower side, the device body 5 is provided with a door cover connecting hole 513 at the side of the cleaning port 511, the bolt includes a head and a rod body, the rod body is connected to the device body 5 at the clamping groove 551 along the door cover connecting hole 513, and the head of the bolt is locked and pressed against the dust suction door cover 52. In the normal dust suction state, the dust suction door cover 52 is fixedly connected to the device body 5 at the cleaning port 511; when it is necessary to disassemble the dust suction door cover 52, the bolt can be rotated to separate the head of the bolt from the dust suction door cover 52, so that the bolt cannot press the dust suction door cover 52. At this time, since the dust suction door cover 52 is provided with the clamping groove 551, the dust suction door cover 52 can be lifted and rotated outward relative to the cleaning port 511, and after the blockage in the device body 5 is cleaned, the dust suction door cover 52 is lowered and the bolt is locked again to press the head of the bolt against the dust suction door cover 52, so that the dust suction door cover 52 can be fixedly connected to the cleaning port 511. In this way, the dust suction door cover 52 does not need to be completely disassembled to facilitate quick connection of the dust suction door cover 52 to the cleaning port 511 for next time dust suction.

[0053] In some embodiments, the dust suction inlet 512 is a plurality of, and the plurality of dust suction inlets 512 are distributed at intervals along the length direction of the device body 5.

[0054] As shown in Figure 1 , Figure 2 and Figure 3 , the device body 5 is provided with a plurality of dust suction inlets 512 distributed at intervals, and dust passes through the plurality of dust suction inlets 512 to reach the inside of the device body 5, thereby improving the dust absorption efficiency to make the identification device 2 more accurate in identifying materials.

[0055] As shown in Figure 2 , a plurality of material receiving devices 4 can be provided at the bottom in the distribution direction of the plurality of dust suction inlets 512, each of the material receiving devices 4 is provided with a waste removing member 3, the plurality of material receiving devices 4 share one device body 5, and each dust suction inlet 512 corresponds to one material receiving device 4, so that one device body 5 can simultaneously absorb dust in a plurality of material receiving devices 4 or more effectively absorb dust in one material receiving device 4.

[0056] In some embodiments, the device body 5 is configured in a cylindrical structure, and the cylindrical structure includes a body part 51 and an end cover 515, and the end cover 515 is connected to the body part 51 through a rounded corner structure.

[0057] In this way, by setting the device body 5 as a dust suction cylinder, and the transition connection between the body part 51 and the end cover 515 also being a rounded corner structure, the device body 5 with a circular cavity can reduce the dead angle inside the dust suction cavity, reduce the settlement of dust in the dust suction cavity, and improve the overall dust removal efficiency.

[0058] In some embodiments, the device body 5 is provided with an exhaust port 561 for connecting to a dust removal fan. In practice, the device body 5 is constructed as a suction tube, and each end of the suction tube is provided with an extension 56 at an angle to the body part 51. Each extension 56 is provided with an exhaust port 561. By setting an angle between the extension 56 and the body part 51, so that the extension 56 and the body part 51 are not on the same straight line, it is convenient to connect to the dust removal fan, and the dust removal fan does not affect the absorption of dust and impurities by the body part 51 of the device body 5.

[0059] In addition, exhaust vents 561 are provided at both ends of the main body 51. By using two dust removal fans to jointly remove dust, impurities and other contaminants from the main body 5, the suction pressure and suction efficiency can be increased.

[0060] In some embodiments, the device body 5 is disposed above the side wall of the waste bin 41, and the dust inlet 512 faces downward, so as to draw dust in the waste bin 41 from the lower edge into the dust inlet 512.

[0061] First, the device body 5 is directly placed on the side wall of the waste bin 41. The unobstructed dust inlet 512 can easily suck up the material together. Moreover, the dust in the waste bin 41 is sucked into the dust inlet 512 from the bottom edge, while the material falls from top to bottom, which can prevent the material from being sucked up. In addition, the dust is relatively light and tends to float upwards. By sucking the dust from bottom to top, it is also easier to suck up the dust.

[0062] In some embodiments, the dust inlet 512 is used to communicate with the dust suction channel 53 located in the waste bin 41. The waste bin 41 is provided with a dust suction baffle 417, and a dust suction channel 53 is formed between the dust suction baffle 417 and the inner wall of the waste bin 41.

[0063] In practice, refer to Figure 1 As shown, a dust suction channel 53 is formed between the dust suction baffle 417 and the side wall of the waste bin 41. The dust suction channel 53 is connected to the dust suction inlet 512. By setting the dust suction channel 53, when the dust removal fan is working, the dust raised in the waste bin 41 is concentrated and guided by the dust removal fan to the dust suction channel 53. Since the dust suction inlet 512 faces the dust suction channel 53 and is connected to the dust suction channel 53, the dust can more easily enter the dust suction inlet 512 of the device body 5, thereby improving the dust removal efficiency in the waste bin 41.

[0064] In some embodiments, the outer side of the device body 5 is covered with flexible pads, including a first flexible pad 7, a second flexible pad 8 and a third flexible pad 6 located at different positions on the outer side of the dust collection device. The device body 5 is provided with a dust collection fixing plate 54 adapted to be pressed between the dust collection baffle 417 through the first flexible pad 7. The device body 5 is used to be pressed between the waste bin 41 through the second flexible pad 8, and the device body 5 is also used to be pressed with the identification device 2 through the third flexible pad 6.

[0065] In practice, as shown in Figure 4 and Figure 5 , the dust collection baffle 417 connected to one end of the device body 5 is provided with a top folding edge 4114, and the top folding edge 4114 of the dust collection baffle 417 is provided with a first flexible pad 7 between the dust collection fixing plate 54. The first flexible pad 7 is sealed by high foaming coefficient rubber plastic polyethylene cotton, which has the advantages of green environmental protection, noise reduction and vibration reduction, long service life, good fireproof performance and good sealing of the connection between the device body 5 and the dust collection baffle 417. The dust in the waste bin 41 is guided by the dust collection channel 53 as much as possible to be sucked into the dust collection cavity, improving the dust collection efficiency.

[0066] In addition, the waste bin 41 is pressed between the device body 5 through the second flexible pad 8, and the device body 5 is pressed with the identification device 2 through the third flexible pad 6.

[0067] The second flexible pad 8 and the third flexible pad 6 are both high foaming coefficient rubber plastic polyethylene cotton, as shown in Figure 4 , the second flexible pad 8 is used to press between the waste bin 41 and the device body 5, which can prevent a large amount of dust from flying out of the waste bin 41 and protect the environment outside the waste bin 41. At the same time, the device body 5 is pressed on the second flexible pad 8, which has a certain buffering effect on the device body 5, preventing hard contact between the device body 5 and the waste bin 41. In addition, during dust removal by the dust removal fan, the device body 5 may vibrate and wear against the waste bin 41. Therefore, the second flexible pad 8 not only seals but also has a buffering effect.

[0068] The third flexible pad 6 is pasted on the tangent line of the device body 5 with a circular tube structure. After the device body 5 is fixed on the identification device 2, the two can be well buffered, which has a buffering effect on the identification device 2, reducing the influence of the vibration of the device body 5 on the identification device 2, that is, reducing the influence of the vibration of the device body 5 on the identification accuracy of the identification device 2 during work.

[0069] The utility model discloses an embodiment further discloses a color sorter 100, including dust extraction device above. In addition, the utility model discloses an embodiment further includes material receiving device 4 and feeding device 1, and material receiving device 4 is equipped with finished product bin 42 and waste bin 41, and finished product bin 42 is located at one side of waste bin 41, and material receiving device 4 is equipped with the feeding port that is communicated with finished product bin 42 and waste bin 41 simultaneously, and the feeding port is equipped with waste removing piece 3, and feeding device 1 conveys material to the position of waste removing piece 3, and waste removing piece 3 is used to blow waste to waste bin 41 after identifying device 2 identifies material.

[0070] In actual, feeding device 1 conveys material to the position of waste removing piece 3, and waste removing piece 3 sprays air towards waste bin 41, so that waste removing piece 3 successfully removes waste to waste bin 41, and finished product can fall into finished product bin 42 by gravity, and finished product flows out from finished product bin outlet 421, and the feeding port can be located directly above finished product bin 42 and above one side of waste bin 41, so that finished product falls into finished product bin 42 by gravity, that is, finished product material and waste are screened by waste removing piece 3, and finished product and waste are screened to different bins respectively, to realize the screening operation of material.

[0071] In some embodiments, waste bin 41 is equipped with waste sampling port, and the waste sampling port is equipped with openable waste sampling door 414, and waste bin 41 is further equipped with waste buffer plate 411, and the waste buffer plate 411 is located at the side of waste sampling door 414 close to waste removing piece 3, and the waste buffer plate 411 forms dust extraction channel 53 with the side wall of waste bin 41 and / or waste sampling door 414, and the dust extraction channel 53 is communicated with dust extraction inlet 512.

[0072] When waste sampling door 414 is opened to sample and analyze waste, waste is easy to overflow from waste sampling door 414, and the waste buffer plate 411 between waste sampling door 414 and the passing space of waste can effectively block material and prevent overflow from the opened waste sampling door 414.

[0073] Specifically, as shown in Figure 1 When waste sampling door 414 is located at waste sampling port of waste bin 41 in an oblique up-down direction, waste buffer plate 411 is parallel to waste sampling door 414 and is located inside waste bin 41, at this time, the bottom of waste buffer plate 411 can be higher than the bottom of waste sampling port, that is, when waste sampling door 414 is opened, due to the effect of waste buffer plate 411, waste does not overflow in large quantities, but the height difference between the bottom of waste buffer plate 411 and the bottom of waste sampling port can make a small amount of waste be taken out from waste sampling port, so as to achieve orderly taking out of waste.

[0074] Figure 13 For the structure of the waste sampling door 414, the waste sampling door 414 includes a lock catch 4142 and a first chain 4141, the waste sampling door 414 can be opened by rotating the first chain 4141, and the waste sampling door 414 is locked with the waste bin 41 through the lock catch 4142, when it is needed to open the waste sampling door 414, the lock catch 4142 is rotated, and the waste sampling door 414 is rotated outward at the first hinge 4141 to open, the principle is the opening mode of a conventional door body and a lock, and when the waste bin 41 needs to be kept closed, the waste sampling door 414 is kept closed.

[0075] It should be noted that the dust baffle 417 can be used as the waste buffer plate 411, and of course the waste buffer plate 411 can exist independently between the dust baffle 417 and play its own role; the dust baffle 417 and the waste buffer plate 411 can also be arranged at different positions of the waste bin 41, for example, arranged on opposite sides or adjacent two sides respectively.

[0076] Referring to Figure 1 It is shown that the waste buffer plate 411 of the embodiment of the utility model is also the dust baffle 417, the waste sampling door 414 is arranged at the position opposite to the dust baffle 417 of the waste bin 41, and the dust baffle 417 is used as the waste buffer plate 411, so as to reduce the internal structure and facilitate manufacturing and assembly.
