Many specific details are set forth in the following description to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.
[0031] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.
[0032] In addition, if the term "and / or" appears, "and / or" is merely a correlative relationship describing associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this text, the character " / " generally indicates that the associated objects before and after are in an "or" relationship. If terms such as "first" and "second" appear, these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" can explicitly or implicitly include at least one such feature. In the description of this application, if the term "plural" appears, the meaning of "plural" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0033] In this application, unless otherwise clearly specified and defined, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense.

If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.
[0036] Refer to Figure 1As shown in the figure, an embodiment of the present application provides a paving device 100, which can be used for the paving process of waste smoke 200 during the waste smoke 200 recovery process, so as to make the paving of waste smoke 200 uniform and avoid affecting subsequent treatment processes due to the accumulation of waste smoke 200. It should be noted that the paving device 100 provided in the present application can be applied to various paving scenarios. For the convenience of understanding, the waste smoke 200 treatment scenario is taken as an example for illustration.
[0037] Specifically, the paving device 100 includes a frame 110, a first paving component 120 and a second paving component 130. The frame 110 can be installed on the ground or a working platform, and both the first paving component 120 and the second paving component 130 are installed on the frame 110. Thus, during the treatment process of waste smoke 200, the waste smoke 200 is successively subjected to multiple thinning and flattening operations by the first paving component 120 and the second paving component 130 to prevent the accumulation of waste smoke 200.
[0038] Refer to together Figure 3 As shown in the figure, the first paving component 120 includes a first driving mechanism 121, at least one vibrating screen 122 and a plurality of first elastic members 123. Among them, each vibrating screen 122 is connected to the output end of the first driving mechanism 121 and vibrates under the drive of the first driving mechanism 121 to shake and disperse the waste smoke 200 located on the vibrating screen 122 and initially thin the accumulated waste smoke 200. The first elastic member 123 is installed on the vibrating screen 122, and the end of each first elastic member 123 away from the vibrating screen 122 is connected to the frame 110 to elastically support the vibrating screen 122. And during operation, it undergoes elastic deformation under the action of the first driving mechanism 121, and then drives the vibrating screen 122 to vibrate. The first elastic members 123 on each vibrating screen 122 are arranged oppositely and are located at both ends of the vibrating screen 122 to ensure the stable vibration of each part of the vibrating screen 122 and fully disperse the waste smoke 200. An outlet is provided on one side of each vibrating screen 122 close to the frame 110, so that the dispersed waste smoke 200 falls onto the second paving component 130 through the outlet.
[0039] Exemplarily, the first elastic member 123 can be a shrapnel structure, so as to have a certain support strength. In the non-operating state, it can stably support the vibrating screen 122, and during the operation process, it can vibrate and deform under the drive of the first driving mechanism 121, and then drive the vibrating screen 122 to vibrate.
[0040] The number of the vibrating screens 122 can be one, two, three, four, etc., which can be selected according to actual needs so that the waste smoke 200 can be spread in an appropriate manner. The number of the first elastic members 123 can also be one, two, three, four, etc., as long as the installation support of the vibrating screen 122 is met. Preferably, each vibrating screen 122 is provided with two first elastic members 123, and the two first elastic members 123 are symmetrically arranged at both ends of the vibrating screen 122 to stably support the vibrating screen 122.
[0041] In some embodiments, a plurality of vibrating screens 122 are provided, and each vibrating screen 122 is stacked at the feeding end of the second paving assembly 130, so as to facilitate the shaking off of the waste smoke 200 after the initial thinning to the second paving assembly 130 for secondary paving. At the same time, the stacking arrangement of the vibrating screens 122 can reduce the overall space occupied by the device and reduce the floor area. Each vibrating screen 122 has a feed port and a discharge port. Among the two adjacent vibrating screens 122, the discharge port of the vibrating screen 122 located above the gravity direction faces the feed port of the vibrating screen 122 located below the gravity direction, so that the waste smoke 200 passes through the vibration dispersion of multiple vibrating screens 122 in sequence, thereby improving the paving uniformity of the waste smoke 200.
[0042] In this embodiment, there are two vibrating screens 122, which are stacked vertically up and down. The discharge port of the upper vibrating screen 122 faces the feed port of the lower vibrating screen 122, so that the waste smoke 200, after being vibrated and thinned by the upper vibrating screen 122, falls into the lower vibrating screen 122 for secondary spreading, so that the waste smoke 200 is fully dispersed.
[0043] Furthermore, a baffle is provided on the peripheral side of the vibrating screen 122 to form an opening structure on the top, which can be the feed port of the vibrating screen 122. At the same time, the baffle is restricted to prevent the waste smoke 200 from scattering from the peripheral side of the vibrating screen 122 during the vibration process.
[0044] Furthermore, the discharge ports of the two vibrating screens 122 are respectively located at ends of the two vibrating screens 122 that are away from each other, thereby increasing the vibration path of the waste smoke 200 .
[0045] See also Figure 2 As shown, in some embodiments, the first driving mechanism 121 includes a driving motor 1211 , an eccentric shaft 1212 , an exciting block 1213 , an input spring piece, a vibration dividing block 1217 and at least one output spring piece 1218 .
[0046] Specifically, the eccentric shaft 1212 is connected to the output shaft of the driving motor 1211 through a transmission structure so as to rotate under the drive of the driving motor 1211. Exemplarily, the transmission structure can be structures such as belts and belt pulleys, chains and sprockets, etc., and no more specific elaboration is made here. The excitation block 1213 is rotatably mounted on the eccentric shaft 1212 and performs reciprocating up and down movement as the eccentric shaft 1212 rotates. The input elastic piece is connected to the end of the excitation block 1213 away from the eccentric shaft 1212, moves up and down following the excitation block 1213, and generates a certain elastic deformation. The sub-vibration block 1217 is rotatably arranged above the frame 110 through a pin shaft, and one side is connected to the input elastic piece, so that during the up and down movement of the input elastic piece, it reciprocally rotates along the pin shaft.
[0047] Exemplarily, the number of output elastic pieces 1218 can be one, two, three, four, five, etc., and can be specifically selected according to the number of vibrating screens 122 to satisfy the connection of one output elastic piece 1218 to one vibrating screen 122. In this embodiment, the number of output elastic pieces 1218 can be two. One end of the output elastic piece 1218 is connected to the sub-vibration block 1217, and the ends away from the sub-vibration block 1217 are respectively connected to the two vibrating screens 122. Thus, during the rotation of the sub-vibration block 1217, the output elastic piece 1218 pulls the corresponding vibrating screen 122 to vibrate, and the paving operation of the waste smoke 200 is carried out.
[0048] In some embodiments, a threaded rod 1214 is provided at the end of the excitation block 1213 away from the eccentric shaft 1212, and a threaded sleeve 1215 is provided at the end of the input elastic piece away from the sub-vibration block 1217. The threaded rod 1214 is in threaded cooperation with the threaded sleeve 1215. Thus, by screwing and moving between the threaded rod 1214 and the threaded sleeve 1215, the distance between the excitation block 1213 and the input elastic piece is adjusted, and the vibration frequency of the vibrating screen 122 is adjusted.
[0049] In one embodiment, the threaded rod 1214 is rotatably connected to the excitation block 1213, and the threaded sleeve 1215 is fixedly connected to the input elastic piece. Thus, by screwing the threaded rod 1214 to rotate relative to the threaded sleeve 1215, the distance between the excitation block 1213 and the input elastic piece can be adjusted.
[0050] In another embodiment, the threaded rod 1214 is fixedly connected to the excitation block 1213, and the threaded sleeve 1215 is rotatably connected to the input elastic piece. Thus, by screwing the threaded sleeve 1215 to rotate relative to the threaded rod 1214, the distance between the excitation block 1213 and the input elastic piece can be adjusted.
[0051] Furthermore, the second paving assembly 130 includes a vibrating trough 131, a second driving mechanism 132, and a second elastic member 133. The vibrating trough 131 is configured to receive the waste tobacco 200 scattered by the first paving assembly 120 and vibrate under the drive of the second driving mechanism 132 to perform a secondary leveling of the waste tobacco 200, ensuring the uniformity of the paving of the waste tobacco 200.
[0052] Specifically, the vibrating trough 131 is installed above the frame 110, and an opening 1311 is provided on the side of the vibrating trough 131 facing away from the frame 110 to receive the material flowing out of the discharge port through the opening 1311. At the same time, a discharge port 1312 is provided at one end of the vibrating trough 131 to discharge the evenly paved material through the discharge port 1312. Exemplarily, the vibrating trough 131 may include a bottom plate and a plurality of baffles located on the periphery of the bottom plate to form a trough structure with an opening 1311 at the top, and the waste tobacco 200 is blocked by each baffle to prevent the waste tobacco 200 from scattering from the side of the vibrating trough 131 during the vibration process.
[0053] Refer to Figure 5 As shown, furthermore, the second driving mechanism 132 includes at least one vibrating motor 1321, and each vibrating motor 1321 is installed at the bottom of the vibrating trough 131 to drive the vibrating trough 131 to perform a vibrating operation and improve the operation intensity of the vibrating trough 131. Exemplarily, the number of vibrating motors 1321 may be one, two, three, four, etc., and can be specifically selected according to actual needs.
[0054] In some embodiments, an inclined surface 134 is provided on the side of the vibrating trough 131 away from the first paving assembly 120, and each vibrating motor 1321 is installed on the side of the inclined surface 134 close to the vibrating screen 122, so as to control the vibration frequency of the vibrating trough 131 through the setting of the inclined surface 134 and limit the feeding speed of the waste tobacco 200.
[0055] In this embodiment, the number of vibrating motors 1321 may be two, and the two vibrating motors 1321 are symmetrically installed at the same end of the inclined surface 134 to synchronously vibrate both sides of the vibrating trough 131 and ensure that the vibration frequencies of each area are the same.
[0056] Furthermore, the second elastic member 133 is respectively connected to the frame 110 and the vibrating trough 131 to provide elastic buffering for the vibration process of the vibrating trough 131, reduce device damage, and extend the service life. Exemplarily, the second elastic member 133 may be a helical spring to provide elastic support during the vibration process of the vibrating trough 131.
[0057] Refer to Figure 4As shown, in some embodiments, the second paving assembly 130 further includes a guide plate 135. The guide plate 135 is installed at one end of the vibrating trough 131 close to the vibrating screen 122 to receive the waste tobacco 200 scattered by the first paving assembly 120 through the guide plate 135, and convey the waste tobacco 200 to the discharge port 1312 under the drive of the drive motor 1211.
[0058] Refer to Figure 6 As shown, in some embodiments, the guide plate 135 has a plurality of guide bars 1351 arranged along the conveying direction. A guide groove 1352 is defined between two adjacent guide bars 1351 to initially lay flat the waste tobacco 200 through the guide groove 1352.
[0059] Specifically, the guide bars 1351 can be installed on the guide plate 135 by welding or other fixing methods, and the spacing between two adjacent guide grooves 1352 can be preset according to design requirements, so that multiple waste tobaccos 200 are laid flat in the guide groove 1352 to make the waste tobacco 200 evenly paved.
[0060] Refer to Figure 4 and Figure 7 As shown, in some embodiments, the second paving assembly 130 further includes at least one sieve plate 136 installed in the vibrating trough 131. Each sieve plate 136 is on the same horizontal plane as the guide plate 135, and one sieve plate 136 is closely arranged with the guide plate 135 to receive the waste tobacco 200 conveyed by the guide plate 135. Each sieve plate 136 is provided with a V-shaped groove 1361, and the groove width of the V-shaped groove 1361 is smaller than the groove width of the guide groove 1352 to further disperse and flatten the waste tobacco 200.
[0061] Exemplarily, the number of sieve plates 136 can be one, two, three, four, etc., and can be specifically selected according to the overall size of the device. In this embodiment, the number of sieve plates 136 can be two, and the V-shaped grooves 1361 of the two sieve plates 136 have the same specifications. The groove width of the V-shaped groove 1361 can be set to be the same as the outer diameter of a single waste tobacco 200, so as to limit the waste tobacco 200 to be arranged in a single form in the V-shaped groove 1361 and flatten the waste tobacco 200 to the greatest extent.
[0062] In some embodiments, the frame 110 includes a main bracket 111 and a sub-bracket 112. The main bracket 111 includes a plurality of columns 1111 and a cross beam 1112. The columns 1111 are connected to the vibrating trough 131 through the second elastic member 133, and one end of the cross beam 1112 is connected to one column 1111. The sub-bracket 112 is connected to the end of the vibrating trough 131 where the vibrating screen 122 is installed and overlaps the cross beam 1112, so as to realize the cross connection between the sub-bracket 112 and the main bracket 111, and make the sub-bracket 112 not fixed to the main bracket 111, increasing the vibration performance of the overall device.
[0063] Specifically, the auxiliary support 112 includes two support rods 1121 and a connecting rod 1122 connecting the two support rods 1121 respectively. One support rod 1121 is connected to the end of the vibration groove 131, and the other support rod 1121 is arranged in the middle of the vibration groove 131 to provide a certain support and protection during the vibration of the vibration groove 131.
