[0035] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] In the prior art, tobacco shreds output by the vibrating conveyor often go moldy and deteriorate. The applicant has discovered that the reason why tobacco shreds go moldy and deteriorate is that the air in the cigarette workshop becomes warm and humid during the cigarette production process, and the surface temperature of the conveying mechanism 2 is low when the vibrating conveyor is stopped, and condensed water is generated when the hot and humid air from the outside contacts the conveying mechanism 2. When the vibrating conveyor conveys tobacco shreds, the dry tobacco shreds absorb moisture in the conveying mechanism 2 and go moldy.

[0037] The embodiment of the utility model provides a vibrating conveyor, such as Figure 1 As shown, it includes a frame 1, a conveying mechanism 2, a protective cover 3 and two shielding curtains 6. The conveying mechanism 2 is arranged on the frame 1, and the conveying mechanism 2 is used to Figure 1 The protective cover 3 is detachably connected to the frame 1, and a through cavity extending in the length direction is provided inside the protective cover 3. The conveying mechanism 2 is provided inside the through cavity, and the through cavity includes an inlet 4 and an outlet 5. The inlet 4 is provided near the input end, and the outlet 5 is provided near the output end. Two shielding curtains 6 are provided on the inlet 4 and the outlet 5, respectively, and each shielding curtain 6 is used to cover the inlet 4 and the outlet 5 when the conveying mechanism 2 stops conveying materials.

[0038] The above technical solution is adopted, by setting a protective cover 3 on the conveying mechanism 2 of the vibrating conveyor, so that the protective cover 3 covers the outside of the conveying mechanism 2, and a shielding curtain 6 that can be opened and closed is set at both ends of the protective cover. When the conveying mechanism 2 conveys tobacco, the lower end of the shielding curtain 6 contacts the tobacco, which can reduce the open area of ​​the inlet 4 and the outlet 5, and reduce the contact of the conveying mechanism 2 with the external airflow. When the conveying mechanism 2 is stopped, the shielding curtain 6 can be used to close the through cavity of the protective cover to prevent the external hot and humid air from entering the conveying mechanism 2 and contacting the inner wall of the conveying mechanism 2 to form condensed water. This prevents the tobacco in the conveying mechanism 2 from contacting the condensed water and becoming moldy and deteriorating.

[0039] Furthermore, the conveying mechanism 2 includes a vibration groove 7, a plurality of rocker arms 8, a connecting frame 9, a connecting rod 10 and a motor 11. The vibration groove 7 is used to convey tobacco. Each rocker arm 8 is respectively arranged along the width direction ( Figure 2 The connecting frame 9 is provided below the vibration groove 7, and the lower ends of the rocker arms 8 are hinged to the connecting frame 9. The connecting frame 9 is provided with a connecting shaft extending along the Y direction. The connecting rod 10 is provided with a first through hole and a second through hole at both ends thereof, and the first through hole is sleeved on the connecting shaft.

[0042] The protective cover 3 includes a top plate 13 and side plates 12 arranged on both sides of the top plate 13 along the width direction. The top plate 13 and the side plates 12 are both made of transparent organic glass, which is convenient for operators to observe the running status of the tobacco on the conveying mechanism 2 through the organic glass. In the length direction, the lengths of the side plates 12 and the top plate 13 are both greater than or equal to the length of the frame 1.

[0043] Furthermore, the upper edge of the shielding curtain 6 is connected to the top plate 13, and the two side edges of the shielding curtain 6 are respectively connected to the two side plates 12. The shielding curtain 6 is provided with an opening extending in the vertical direction, and a zipper 19 is provided on the opening. The zipper 19 is used to close the opening when the conveying mechanism 2 stops running. Specifically, the number of openings can be one, and the distance between the opening and the two side plates 12 is equal (such as Figure 2 As shown), the number of openings can also be two, and the two openings are respectively arranged near the two side panels 12. When the conveying mechanism 2 conveys tobacco, the tobacco can push the shielding curtains 6 on both sides of the opening to open, and the shielding curtains 6 can smooth the tobacco passing through the opening.

Figure 1As shown, the first cover body 14 and the second cover body 15 are detachably connected, and the second cover body 15 covers the output end. In the process of conveying tobacco, tobacco is easy to gather briefly at the output end and rub against the protective cover 3, causing the protective cover 3 to wear out the part close to the output end. By setting the second cover body 15, the second cover body 15 can be replaced according to the degree of wear, reducing the maintenance cost. The first cover body 14 includes a top plate 13 and side plates 12 arranged on both sides of the top plate 13 along the width direction. The top plate 13 and the side plates 12 are made of transparent organic glass, which is convenient for operators to observe the operation of tobacco on the conveying mechanism 2 through the organic glass. The second cover body 15 includes a bracket 16 and a waterproof cloth 17. The waterproof cloth 17 can be transparent or opaque. The bracket 16 is detachably connected to the frame 1. The shape of the bracket 16 is a rectangular parallelepiped. The waterproof cloth 17 covers the top surface and side surface of the bracket 16. The end of the bracket 16 away from the entrance 4 is provided with a shielding curtain 6.

[0046] Furthermore, the upper edge of the shielding curtain 6 is connected to the upper edge of the bracket 16, and the two side edges of the shielding curtain 6 are respectively connected to the two side edges of the bracket 16. The shielding curtain 6 is provided with an opening extending in the vertical direction, and a zipper 19 is provided on the opening. The zipper 19 is used to close the opening when the conveying mechanism 2 stops running. Specifically, the number of openings can be one, and the distance between the opening and the two side panels 12 is equal (such as Figure 2 As shown), the number of openings can also be two, and the two openings are respectively arranged near the two side panels 12. When the conveying mechanism 2 conveys tobacco, the tobacco can push the shielding curtains 6 on both sides of the opening to open, and the shielding curtains 6 can smooth the tobacco passing through the opening.
