At the same time, a lot of tobacco dust is also loaded into the waste bin along with the waste materials. During the waste recycling process, the excess tobacco dust needs to be separated from the rest. Currently, the screening of waste tobacco dust is done manually using winnowing baskets, which is labor-intensive, inefficient, and has unsatisfactory results. The operating site is also messy with tobacco dust scattered all around. Utility Model Content

[0022] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0023] like Figure 1As shown, this application provides a smoke screening mechanism, including a frame 1, a vibrating groove 2, a spring 4, a first pneumatic pump (not shown in the figure), a second pneumatic pump (not shown in the figure), a material loading tray 5, and a material receiving tray 3.

[0024] The vibrating groove 2 is mounted on the frame 1 via a spring 4. The material tray 5 is mounted on the frame and located above the vibrating groove, with the material tray's outlet located at the upper left of the vibrating groove. The receiving tray is mounted on the frame below the vibrating groove. The first pneumatic pump is mounted at the bottom of the vibrating groove, and the second pneumatic pump is mounted at the bottom of the receiving tray. Both the first and second pneumatic pumps are connected to an air source.

[0025] In this application, the frame 1 includes a frame body 11 and a material tray support frame 13 located on the left side of the frame body. Rollers with brakes are provided below the frame body 11 for easy movement and fixation. A receiving tray support frame 12 is inclinedly arranged within the frame body; the material tray is disposed on the material tray support frame, and the receiving tray 3 is disposed on the receiving tray support frame 12. The vibrating groove 2 is disposed above the frame body 11 via a spring 4.

[0026] The frame body 11 is a cuboid structure composed of four uprights 111, four lower connecting beams 112, and four upper connecting beams 113. In this application, the uprights, lower connecting beams, and upper connecting beams are all made of square tubing with a square cross-section. Figure 1 As shown, four lower connecting beams are fixedly installed near the lower end of the four columns, and four upper connecting beams are fixedly installed on the upper end face of the four columns. On the two longer upper connecting beams, three support columns 114 are provided for the lower end of the spring 4 to be inserted.

[0027] The receiving tray support frame 12 includes a first inclined beam 121, a second inclined beam 122, and multiple crossbeams 123 disposed between the first inclined beam 121 and the second inclined beam 122. The first inclined beam, second inclined beam, and crossbeams of this application are also made of square tubing with a square cross-section. The first inclined beam is disposed between two front columns, and the second inclined beam is disposed between two rear columns, with the first and second inclined beams parallel to each other. The receiving tray is fixed to the receiving tray support frame by bolts, which pass through the receiving tray and the crossbeams and are then connected and fixed by nuts.

[0028] The lower bottom beam 131 of the material tray support frame 13 of this application is on the same plane and fixedly connected to the upper connecting beam 113. Four support columns 132 are provided on the lower bottom beam 131, and cross beams 133 are provided on the four support columns 132 to support the material tray. A reinforcing beam 134 is also provided between the bottom beam and the frame body.

[0029] The material carrier tray of this application includes a tray body without a top cover, and a discharge port is provided on the side of the tray body opposite to the vibrating trough. In other embodiments of this application, a third pneumatic pump is provided at the bottom of the tray to vibrate the tray, vibrating the waste material falling into the tray onto the vibrating trough. In other embodiments of this application, after the waste material is poured onto the tray, it is manually metered and directed into the vibrating trough to avoid excessive waste material entering the vibrating trough and affecting the dust screening effect.

[0030] In this application, the vibrating trough 2 includes a vibrating trough body, a waste outlet is provided at the right end of the vibrating trough body, φ5 screen holes 21 are evenly distributed at the bottom of the vibrating trough, and multiple spring mounting columns 22 are provided on both sides below the vibrating trough body, with the length of the spring mounting columns decreasing from left to right.

[0031] The number of springs 4 is the same as the number of spring mounting posts 22, and the length of the springs decreases from left to right. During installation, the springs are respectively fitted onto the support posts of the upper connecting beam and the spring mounting posts below the vibration groove. After installation, the vibration groove is inclined relative to the upper connecting frame body, and the springs play a role in buffering and damping vibration. When the upper end face of the support post abuts against the lower end face of the spring mounting post, it limits the vibration of the vibration groove.

[0032] A first pneumatic pump is installed at the bottom of the vibrating trough to provide power. Under the combined action of the spring and the tilt of the vibrating trough, the waste material is shaken, loosened and directionally conveyed. During this process, fine dust falls down to the receiving tray through the holes on the bottom plate of the vibrating trough.

[0033] In other embodiments of this application, a purging pipeline (not shown in the figure) is provided below the vibrating groove 2. The purging pipeline is connected to the air source through a pipeline. When the screen holes of the vibrating groove are blocked, the purging pipeline is opened to purge the screen holes in the reverse direction.

[0034] The receiving tray 3 is installed on the receiving tray support frame and is inclined (the bottom end is the smoke outlet section). A second pneumatic pump is installed at the bottom to make the smoke move in a direction on the receiving tray, which is convenient for collection and does not accumulate.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
