Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to a vibrating trough conveying device. Background Technology

[0002] In tobacco production, vibrating troughs are commonly used to loosen and convey tobacco leaves due to technological requirements. Vibrating troughs are typically arranged in two stages. The downstream trough is positioned below the upstream trough and receives the tobacco leaves from its outlet. Normally, the amplitude and frequency of the two troughs differ during operation. This creates a strong positive pressure near the junction of the two troughs due to their relative motion. Falling tobacco leaves are then blown out of the downstream trough by this positive pressure, resulting in significant material leakage and spillage.

[0003] To address this, related technologies involve installing a material discharge baffle at the outlet of the upstream vibrating trough, extending towards the downstream vibrating trough to reduce the impact of positive pressure air on the tobacco leaves. However, a certain gap needs to be set between the material discharge baffle and the downstream vibrating trough to prevent collisions during vibration. As a result, the tobacco leaves will still be affected by positive pressure air as they travel from the material discharge baffle to the downstream vibrating trough, failing to effectively solve the problems of material leakage and severe material throwing. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating trough conveying device to solve the problems of serious material leakage and throwing of tobacco leaves during the vibrating trough conveying process.

[0005] This utility model provides a vibrating trough conveying device, including an upper vibrating trough, a lower vibrating trough, and a connecting assembly. Both the upper and lower vibrating troughs are used for conveying materials. The lower vibrating trough is located below the upper vibrating trough and is used to receive materials from the discharge end of the upper vibrating trough. The connecting assembly includes a connecting plate, an upper baffle, and a lower baffle. The connecting plate is fixedly connected to the lower vibrating trough, and the connecting plate is set at an angle to the bottom of the lower vibrating trough. The upper baffle is fixedly connected to the upper end of the connecting plate, and the lower baffle is fixedly connected to the lower end of the connecting plate. Both the upper and lower baffles are capable of elastic deformation. The upper baffle abuts against the outer surface of the bottom of the upper vibrating trough, and the lower baffle abuts against the inner surface of the bottom of the lower vibrating trough.

[0006] As a preferred technical solution for the vibrating trough conveying device, both sides of the connecting plate are provided with flanges, and the flanges are fixedly connected to the side plate of the lower vibrating trough.

[0007] As a preferred technical solution for the vibrating trough conveying device, the connecting plate is provided with a flat plate portion and an opening portion along the material conveying direction, and the opening portion is provided with multiple air vents.

[0008] As a preferred technical solution for the vibrating trough conveying device, the diameter of the vent hole is 0.5mm-2mm.

[0009] As a preferred technical solution for the vibrating trough conveying device, a water collection trough is provided on the opening portion. The water collection trough extends along the conveying direction perpendicular to the material and is used to collect condensate on the connecting plate.

[0010] As a preferred technical solution for the vibrating trough conveying device, the water collection trough is a V-shaped trough or a U-shaped trough.

[0011] As a preferred technical solution for the vibrating trough conveying device, two water collection troughs are provided, and the two water collection troughs are distributed in parallel along the material conveying direction.

[0012] As a preferred technical solution for the vibrating trough conveying device, the angle between the connecting plate and the bottom of the lower vibrating trough is 50°-70°.

[0013] As a preferred technical solution for the vibrating trough conveying device, it also includes a draining perforated plate, which is located between the bottom of the lower vibrating trough and the connecting assembly. The lower baffle abuts against the draining perforated plate, and the draining perforated plate can drain condensate to the bottom of the lower vibrating trough.

[0014] As a preferred technical solution for the vibrating trough conveying device, the lower vibrating trough is provided with a drain pipe, which is used to drain the condensate at the bottom of the lower vibrating trough.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides a vibrating trough conveying device. By fixing an upper baffle and a lower baffle to the upper and lower ends of a connecting plate, both the upper and lower baffles can undergo elastic deformation. The upper baffle abuts against the outer surface of the bottom of the upper vibrating trough, and the lower baffle abuts against the inner surface of the bottom of the lower vibrating trough. Thus, when the upper and lower vibrating troughs vibrate, the upper and lower baffles undergo elastic deformation and always remain in contact with the upper and lower vibrating troughs. During the process of the material falling from the upper vibrating trough to the lower vibrating trough, it always stays on the connecting plate, which avoids the influence of positive pressure air to a certain extent, thereby greatly reducing material leakage and material throwing.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] like Figures 1-4 As shown, this utility model provides a vibrating trough conveying device, including an upper vibrating trough 1, a lower vibrating trough 2, and a connecting assembly 4. Both the upper vibrating trough 1 and the lower vibrating trough 2 are used to convey materials; in this embodiment, the material is tobacco leaves. The lower vibrating trough 2 is located below the upper vibrating trough 1 and downstream of the upper vibrating trough 1 along the material conveying direction. The lower vibrating trough 2 is used to receive and convey the material from the discharge end of the upper vibrating trough 1. The connecting assembly 4 includes a connecting plate 41, an upper baffle 44, and a lower baffle. The connecting plate 41 is fixedly connected to the lower vibrating trough 2, forming an angle with the bottom wall of the lower vibrating trough 2, and extends towards the upper vibrating trough 1. The upper baffle 44 is fixedly connected to the upper end of the connecting plate 41 via an upper pressure strip 45. The lower baffle (not shown in the figure) is fixedly connected to the lower end of the connecting plate 41 via a lower pressure strip 42 and a side pressure strip 43. Both the upper baffle 44 and the lower baffle are capable of elastic deformation. The upper baffle 44 abuts against the outer surface of the bottom of the upper vibrating trough 1, and the lower baffle abuts against the inner surface of the bottom of the lower vibrating trough 2. When the upper vibrating trough 1 and the lower vibrating trough 2 vibrate, the upper baffle 44 and the lower baffle undergo elastic deformation and always remain in contact with the upper vibrating trough 1 and the lower vibrating trough 2. During the process of the material falling from the upper vibrating trough 1 to the lower vibrating trough 2, it always stays on the connecting plate 41, which to a certain extent avoids the influence of positive pressure air, thereby greatly reducing material leakage and material throwing.

[0028] Specifically, both sides of the connecting plate 41 are provided with flanges 414, and the flanges 414 are fixedly connected to the side plate of the lower vibrating groove 2 by fasteners, so as to avoid the fasteners being located on the material conveying channel and obstructing the material conveying.

[0029] Furthermore, such as Figure 1 and Figure 3As shown, along the material conveying direction, the connecting plate 41 is provided with a flat plate portion 411 and an opening portion 412, with multiple ventilation holes in the opening portion 412. These ventilation holes are evenly distributed in a matrix on the opening portion 412. The ventilation holes can guide the positive pressure air, reducing its intensity and further reducing its impact on the tobacco leaves, thus minimizing material leakage and spillage. Furthermore, the ventilation holes on the connecting plate 41 can also drain some of the condensate generated in the previous process, preventing the condensate from affecting the tobacco leaves. The diameter of the ventilation holes is set to 0.5mm-2mm, for example, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, or 2mm. In this embodiment, the vent hole has a diameter of 1mm, which ensures the smooth flow of positive pressure air while also filtering out small particles of dust and other waste materials mixed in with the tobacco leaves.

[0030] Optionally, a water collection trough 413 is also provided on the opening 412. The water collection trough 413 extends perpendicular to the material conveying direction and is used to collect condensate on the connecting plate 41. Part of the condensate on the connecting plate 41 drains out through the vent holes, while the other part flows along the surface of the connecting plate 41 to the water collection trough 413, where it accumulates and drains out through the vent holes. By providing the water collection trough 413, the drainage effect of the connecting plate 41 on condensate is improved.

[0031] Specifically, the water collection tank 413 is configured as a V-shaped or U-shaped groove, which can effectively prevent the condensate accumulated in the water collection tank 413 from overflowing. In addition, there are two or more water collection tanks 413, which are distributed in parallel along the material conveying direction to improve the drainage effect of condensate.

[0032] In this embodiment, the upper vibrating trough 1 and the lower vibrating trough 2 are arranged in parallel. The angle between the connecting plate 41 and the bottom of the lower vibrating trough 2 is 50°-70°, for example, it can be 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69° or 70°. In this embodiment, the angle between the connecting plate 41 and the bottom of the lower vibrating trough 2 is 60°, so that the material falls at an appropriate speed, avoiding being thrown out by the vibrating lower vibrating trough 2 due to falling too fast, and also avoiding conveying jams due to falling too slowly.

[0033] Furthermore, such as Figure 1As shown, the vibrating trough conveying device also includes a draining perforated plate 3, which is located between the bottom of the lower vibrating trough 2 and the connecting assembly 4. The lower baffle abuts against the draining perforated plate 3, allowing the draining perforated plate 3 to drain condensate to the bottom of the lower vibrating trough 2. This also drains any condensate that has not drained from the connecting plate 41 onto the draining perforated plate 3, preventing the condensate from affecting the tobacco leaves. The lower vibrating trough 2 is also equipped with a drain pipe 21, located at the bottom of the lower vibrating trough 2. The drain pipe 21 is used to drain the condensate at the bottom of the lower vibrating trough 2. The condensate drained from the connecting plate 41 and the condensate drained from the draining perforated plate 3 accumulates at the bottom of the lower vibrating trough 2 and is discharged through the drain pipe 21.

[0034] When using the vibrating trough conveying device in this embodiment to convey tobacco, the draining perforated plate 3 is placed in the lower vibrating trough 2. The connecting plate 41 is fixedly connected to the lower vibrating trough 2 by the two flanges 414 of the connecting plate 41. The upper baffle 44 is installed on the upper end of the connecting plate 41 by the upper pressure strip 45, and the lower baffle is installed on the lower end of the connecting plate 41 by the lower pressure strip 42 and the two side pressure strips 43. The upper baffle 44 abuts against the outer surface of the bottom of the upper vibrating trough 1, and the lower baffle abuts against the draining perforated plate 3. During the operation of the upper vibrating trough 1 and the lower vibrating trough 2, the tobacco leaves are conveyed from the upper vibrating trough 1 to the lower vibrating trough 2. When passing through the connecting plate 41, the tobacco leaves are less affected by the positive pressure wind. At the same time, some condensate water can be drained, reducing the loss of tobacco leaves during the production process.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
