[0044] like Figure 2 and Figure 5-Figure 7 As shown, the frame 1 is a rectangular frame, and sliding grooves are provided on the inner walls of the left and right frames of the frame 1.

[0045] like Figure 2-Figure 4 and Figure 6-Figure 12 As shown, both side edges of the gauze net 2 are slidably assembled in the slide grooves of the frame 1 , and a plurality of positioning holes 21 are provided on both side edges of the gauze net 2 for use in conjunction with the winding mechanism 4 .

[0046] like Figure 6-Figure 10As shown, the winding box 3 is divided into an upper accommodating chamber 31 and a lower storage chamber 32 by a partition. A first strip hole 33 is provided on the top of the winding box 3, and the first strip hole 33 allows the gauze 2 to enter the winding box 3. A second strip hole 34 is provided between the accommodating chamber 31 and the storage chamber 32. The accommodating chamber 31 and the storage chamber 32 are connected through the second strip hole 34, so that the sundries dropped into the accommodating chamber 31 can enter the storage chamber 32 through the second strip hole 34. A storage box is movably installed in the storage chamber 32, so that the storage box can be replaced in time. The accommodating chamber 31 is connected to the first strip hole 33, and grooves are also provided on the left and right side walls of the accommodating chamber 31 for the rotatable installation of the winding mechanism 4, the shaking mechanism 5, and the rotary scraping mechanism 7.

[0047] like Figure 3 and Figure 6-Figure 12 As shown, the winding mechanism 4 includes a winding rod 41, a first guide rod 42, a second guide rod 43, a belt transmission mechanism 44, and a driving motor 45. The winding rod 41, the first guide rod 42, and the second guide rod 43 are arranged parallel to each other, and both ends of the winding rod 41, the first guide rod 42, and the second guide rod 43 are installed in grooves on the left and right side walls of the accommodating chamber 31 around an axis extending left and right. In this embodiment, both ends of the winding rod 41, the first guide rod 42, and the second guide rod 43 are placed in the grooves for rotation. In other embodiments, bearings can be installed on the left and right side walls of the accommodating chamber 31, and both ends of the winding rod 41, the first guide rod 42, and the second guide rod 43 are placed in the bearings for rotation. The installation method of the winding rod 41, the first guide rod 42, and the second guide rod 43 in the accommodating chamber 31 is a conventional rotation installation method, which will not be described in detail. The winding rod 41, the first guide rod 42 and the second guide rod 43 are synchronously rotated by a belt transmission mechanism 44. In this embodiment, the belt transmission mechanism 44 is a belt. In other embodiments, the belt transmission mechanism 44 can also be a chain mechanism. A driving motor 45 is installed on the inner wall of the accommodating chamber 31. The driving motor 45 is equipped with a first gear 451 for driving the winding rod 41 to rotate.

[0048] Specifically, Figure 3 and Figure 6-Figure 12 As shown, a second gear 411 is provided at one end of the winding rod 41 close to the driving motor 45, and the second gear 411 is meshed with the first gear 451. The driving motor 45 drives the second gear 411 to rotate through the first gear 451, thereby driving the winding rod 41 to rotate and wind up the gauze 2.

[0049] like Figure 3 and Figure 6-Figure 12 As shown, the first guide rod 42 and the second guide rod 43 are provided with guide wheels, and a plurality of protrusions are evenly distributed on the guide wheels. When the guide wheels rotate, the protrusions are inserted into a plurality of positioning holes 21 on the gauze 2. With the cooperation of the protrusions and the positioning holes 21, the gauze 2 located between the first guide rod 42 and the second guide rod 43 has a slack section.

[0050] like Figure 11-Figure 14 As shown, the shaking mechanism 5 includes a rectangular frame 51, a shaking member 52, and a driving assembly 53. The rectangular frame 51 is fixedly installed in the winding box 3, the shaking member 52 is slidably assembled in the rectangular frame 51, and the driving assembly 53 is connected to the shaking member 52 and drives the shaking member 52 to move back and forth in the rectangular frame 51.

[0051] like Figure 11-Figure 14 As shown, the shaking member 52 includes a limit block 521 and a connecting column 522. The limit block 521 is slidably installed in the rectangular frame 51 through the connecting column 522, and a through slot 5211 is provided on the limit block 521 for the slack section of the gauze 2 to pass through. When the limit block 521 moves back and forth in the rectangular frame 51, the limit block 521 drives the slack section to move back and forth, and the sundries hanging on the slack section are shaken off.

[0052] like Figure 11-Figure 14 As shown, the driving assembly 53 includes a rack 531, a shaking motor 532, a partial gear 533, a reset spring 534, and a mounting plate 535. The rack 531 is connected to the limit block 521 through a connecting column 522, and the rack 531 and the limit block 521 are respectively located on both sides of the rectangular frame 51. The shaking motor 532 is mounted on the mounting plate 535, and the two ends of the mounting plate 535 are respectively rotated and sleeved on the outside of the first guide rod 42 and the second guide rod 43. The partial gear 533 is assembled on the shaking motor 532 and meshed with the rack 531, so as to drive the rack 531 to move through the partial gear 533, and then drive the limit block 521 to move. The connecting column 522 is connected to the rectangular frame 51 through a reset spring 534, and when the rack 531 and the partial gear 533 are disengaged, the limit block 521 is driven to move in the opposite direction for reset.

[0053] Among them, Figure 11-Figure 14 As shown, the rack 531 includes a first tooth segment 5311 and a second tooth segment 5312, and the partial gear 533 is an incomplete tooth, including a gear tooth segment 5331 and an empty tooth segment 5332. When the gear tooth segment 5331 is engaged with the first tooth segment 5311, the rack 531 moves in the rectangular frame 51. When the empty tooth segment 5332 contacts the first tooth segment 5311, the rack 531 is disengaged from the partial gear 533, and the rack 531 moves and resets in the rectangular frame 51 under the action of the reset spring 534.

[0054] Specifically, the partial gear 533 is driven to rotate by the shaking motor 532. When the gear segment 5331 meshes with the first tooth segment 5311, the rack 531 moves in the rectangular frame 51 and drives the limit block 521 to move upward in the rectangular frame 51 through the connecting column 522. The gauze 2 passes through the through groove 5211 of the limit block 521 and moves upward together with the limit block 521. The reset spring 534 is squeezed at the upper end of the rectangular frame 51 by the connecting column 522. When the empty tooth segment 5332 contacts the first tooth segment 5311, the rack 531 is disengaged from the partial gear 533. The rack 531 moves and resets in the rectangular frame 51 under the action of the reset spring 534, and drives the limit block 521 to move downward quickly with the gauze 2, shaking off the debris hanging on the gauze 2, and ensuring the cleanliness of the gauze 2.

[0055] like Figure 7 and Fig.11 As shown, two groups of bellows 6 are provided, which are spaced apart between the first guide rod 42 and the second guide rod 43. The bellows 6 include a box body 61, an air nozzle 62 and a fan. The fan is provided in the box body 61 to supply air to the air nozzle 62. Supplying air through the fan is a relatively conventional method and is not described in detail. The air nozzle 62 has a plurality of spaced apart portions arranged on the box body 61. The air nozzle 62 faces the gauze 2, so as to facilitate blowing of the slack section of the gauze 2 between the first guide rod 42 and the second guide rod 43, so as to blow off the debris hanging on the slack section of the gauze 2 and improve the cleaning effect of the gauze 2.

[0056] like Figure 6-Figure 10 As shown, the scraping mechanism 7 includes a fixed plate 71, a hollow shaft 72, a rotating roller 73, and a scraper 74. The fixed plate 71 is installed on the inner wall of the accommodating chamber 31, and is staggered with the second strip holes 34, leaving the second strip holes 34. The end of the hollow shaft 72 away from the shaking mechanism 5 is fixedly installed on the inner wall of the accommodating chamber 31, the rotating roller 73 is sleeved on the outer peripheral wall of the hollow shaft 72, and can rotate around the hollow shaft 72. The scraper 74 is installed on the rotating roller 73, and a third gear 731 is provided at the end of the rotating roller 73 close to the shaking mechanism 5. The third gear 731 is meshed with the second tooth segment 5312 of the rack 531.

[0057] like Figure 6-Figure 10 As shown, specifically, Fig.10 As shown in the figure, when viewed from the left side of the winding box 3, the initial position of the scraper 74 is located on the right side of the fixed plate 71. When the gear segment 5331 of the partial gear 533 contacts the first gear segment 5311 of the rack 531, the rack 531 is driven to move upward in the rectangular frame 51, and the second gear segment 5312 of the rack 531 contacts and meshes with the third gear 731, and drives the third gear 731 and the rotating roller 73 to rotate counterclockwise, thereby driving the scraper 74 to rotate counterclockwise until the scraper 74 rotates to the position shown in the figure. Figure 6As shown, at the left side of the fixed plate 71 , the scraper 74 scrapes the debris dropped from the gauze 2 onto the scraper 74 during counterclockwise rotation, and then the debris scraped and collected on the scraper 74 can fall into the second strip hole 34 and then enter the storage cavity 32 .

[0058] like Figure 6-Figure 10 As shown, a plurality of air holes 721 penetrating the shaft body of the hollow shaft 72 are provided in the length direction of the hollow shaft 72, and a plurality of air jets 732 corresponding to the air holes 721 are provided on the rotating roller 73. The air jets 732 and the scraper 74 are staggered. When the rotating roller 73 rotates around the hollow shaft 72 until the air holes 721 and the air jets 732 coincide with each other, gas is ejected from the air jets 732 to blow the debris on the scraper 74 off into the second strip hole 34, thereby ensuring the cleaning effect of the scraper 74. In this embodiment, the hollow shaft 72 can be connected to a conventional air supply mechanism such as an air pump, an air cylinder, or a fan at the end away from the shaking mechanism 5 to provide gas or wind to the hollow inside of the hollow shaft 72. Such mechanisms for providing gas or wind belong to conventional prior art and will not be described in detail.

[0059] like Figure 3-Figure 4 and Figure 9-12 As shown, the traction mechanism 8 includes a large reel 81, a small reel 82, and a traction rope 83. The large reel 81 is installed on the driving motor 45. There are several small reels 82, which are rotatably installed on the winding box 3 and the frame 1 respectively. One end of the traction rope 83 is wound around the large reel 81, and the other end is connected to one end of the gauze 2 against the inner wall of the upper frame of the frame 1. The middle part of the traction rope 83 is wound around the small reel 82.

[0060] like Figure 3-Figure 4 and Figure 9-12 As shown, combined Fig.10 As shown in the description, when observed from the left side of the winding box 3, when the first gear 451 of the driving motor 45 rotates clockwise, the second gear 411 is driven to rotate counterclockwise to drive the winding rod 41 to wind up the gauze 2, and the winding rod 41 pulls the lower end of the gauze 2 to move, and the large reel 81 rotates clockwise with the first gear 451, so that one end of the traction rope 83 wound on the large reel 81 is unwound, so that the traction rope 83 connected to the gauze 2 moves downward with the upper end of the gauze 2. After the gauze 2 is cleaned of the debris hanging on it, the first gear 451 of the driving motor 45 rotates counterclockwise, and then one end of the traction rope 83 wound on the large reel 81 is reeled on the large reel 81, and the other end lifts the gauze 2 upward. The function of the small reel 82 is to facilitate the movement of the traction rope 83.

[0061] Working process:

[0062] like Figure 3-Figure 4 and Figure 6-Figure 12As shown, observed from the left side of the winding box 3, under the drive of the driving motor 45, the first gear 451 rotates clockwise, and the large winding wheel 81 rotates clockwise with the first gear 451, so that one end of the traction rope 83 wound on the large winding wheel 81 is unwound, and the other end moves downward with the upper end of the gauze net 2, and the first gear 451 drives the winding rod 41 to rotate through the second gear 411 to pull the lower end of the gauze net 2 to rotate and wind it on the winding rod 41.

[0063] At the same time, the partial gear 533 is driven to rotate by the shaking motor 532. When the gear segment 5331 meshes with the first tooth segment 5311, the rack 531 moves in the rectangular frame 51 and drives the limit block 521 to move upward in the rectangular frame 51 through the connecting column 522. The gauze 2 passes through the through groove 5211 of the limit block 521 and moves upward together with the limit block 521. The reset spring 534 is squeezed at the upper end of the rectangular frame 51 by the connecting column 522. When the empty tooth segment 5332 contacts the first tooth segment 5311, the rack 531 is disengaged from the partial gear 533. The rack 531 moves and resets in the rectangular frame 51 under the action of the reset spring 534, and drives the limit block 521 to move downward quickly with the gauze 2, shaking off the debris hanging on the gauze 2, and ensuring the cleanliness of the gauze 2.

[0064] When viewed from the left side of the winding box 3, the initial position of the scraper 74 is located on the right side of the fixed plate 71. When the gear segment 5331 of the partial gear 533 contacts the first gear segment 5311 of the rack 531, the rack 531 is driven to move upward in the rectangular frame 51, and the second gear segment 5312 of the rack 531 contacts and meshes with the third gear 731, and drives the third gear 731 and the rotating roller 73 to rotate counterclockwise, thereby driving the scraper 74 to rotate counterclockwise until the scraper 74 rotates to the position shown in FIG. Figure 6 As shown, at the left side of the fixed plate 71, the scraper 74 scrapes the debris that falls from the screen 2 onto the scraper 74 during counterclockwise rotation. When the air holes 721 correspond to the air jets 732 one by one, gas is ejected from the air jets 732 to blow the debris on the scraper 74 into the second strip hole 34 and then into the storage chamber 32.

[0065] In other embodiments, in order to enable the gauze 2 to be unfolded upward, a reel can be provided at the top of the frame 1 and equipped with a motor, and a traction rope 83 can be wound around the reel to achieve the effect of lifting the gauze 2 upward. A pulley can also be provided at the upper end of the gauze 2, and a traction rope 83 can be wound around the pulley. The traction rope 83 can be manually pulled to lift the gauze 2 upward and unfold it. The above is only a more preferred embodiment of the present invention, and other mechanisms that can lift the gauze 2 upward are also possible, without making too many restrictions.

[0066] In other embodiments, the bellows 6 and the scraping mechanism 7 may be eliminated, and the second strip hole 34 may be opened larger so that the storage chamber 32 is directly located below the slack section of the gauze 2, thereby facilitating the collection of debris dropped from the gauze 2.

[0067] In other embodiments, in order to facilitate the installation of the shaking motor 532 , the shaking motor 532 may also be directly installed on the winding box 3 .

[0068] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "width", "horizontal", "top", "bottom", "inside", "outside" and the like, which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the drawings of this specification, and are only for the purpose of facilitating the explanation of the scheme of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the present invention.
