[0034] However, the moisture content of the tobacco to be dried is relatively high, and there will be wet balls and agglomerations, which will lead to uneven thickness and incorrect position of the tobacco thrown to the fluidized bed by the vibration trough, resulting in uneven drying of the tobacco on the fluidized bed, affecting the quality requirements of the tobacco.
[0035] In the embodiment of the utility model, by arranging inclined first and second guide plates at the material inlet end of the vibration trough and arranging a material dispersion unit at the material outlet end of the vibration trough, wet balls and agglomerated tobacco are initially dispersed under the action of the first and second guide plates, and then the material dispersion unit is used to evenly disperse the tobacco, thereby changing the distribution of the tobacco on the vibration trough, thereby improving the uniformity of the tobacco entering the fluidized bed, providing better conditions for the fluidized bed to dry the tobacco, thereby solving the problem of uneven feeding in the vibration trough.
[0036] Combine the following Figures 1 to 3 The utility model is described in detail. The utility model relates to a vibrating conveyor material leveling device.

The vibration trough 1 is arranged on the vibration conveyor, and the vibration trough 1 can intermittently vibrate on the vibration conveyor. The vibration trough 1 is used to receive tobacco conveyed from the previous process. After the intermittent vibration of the vibration trough 1, the tobacco is thrown to the next fluidized bed drying equipment to dry the tobacco. Baffles are provided on both sides of the vibration trough 1 to prevent the tobacco in the vibration trough 1 from falling from both sides of the vibration trough 1 during the vibration process, but can only move along the conveying direction of the vibration trough 1. The vibration trough 1 has a material inlet end and a material outlet end. The first guide plate 2 and the second guide plate 3 are arranged on the vibration trough 1 and are located at the material inlet end of the vibration trough 1.

The first guide plate 2 and the second guide plate 3 can be completely symmetrically arranged with respect to the central axis of the vibration groove 1, or they can be staggered, but a material tightening area must always be formed between the first guide plate 2 and the second guide plate 3, the material tightening area is used to receive the tobacco delivered from the previous process of the vibration groove 1, and a guide port 4 is formed at the end of the first guide plate 2 and the second guide plate 3 away from the material inlet end, that is, the guide port 4 is formed on the side of the material tightening area away from the material inlet end, the first guide plate 2 and the second guide plate 3 can be made of a stainless steel plate with a thickness of 2 mm cut into a rectangular shape, or angle steel can be used, the first guide plate 2 and the second guide plate 3 can be welded to the vibration groove 1 by welding, the height of the first guide plate 2 and the second guide plate 3 can be consistent with the height of the baffles on both sides of the vibration groove 1, or can be higher than the height of the baffles on both sides of the vibration groove 1.
[0038] The material dispersing unit 5 is arranged at the material outlet end of the vibration trough 1. The material dispersing unit 5 is connected to the material tightening area through the guide port 4. The material dispersing unit 5 is used to disperse the material diverted from the guide port 4. Specifically, the material dispersing unit 5 may include a plurality of rollers. The wet balls and agglomerated tobacco are broken up by the blocking of the plurality of rollers, accompanied by the vibration of the vibration trough 1, so that the tobacco on the vibration trough 1 is evenly thrown to the fluidized bed for drying. The plurality of rollers in the material dispersing unit 5 may be arranged in parallel along the material transport direction, or may be arranged in a scattered manner, that is, the inclination directions of the plurality of rollers are inconsistent, and a certain gap is left between the rollers for the tobacco to pass through, which can further improve the uniformity of the distribution of the tobacco on the vibration trough 1 and ensure that the tobacco falls evenly on the fluidized bed for drying.
[0039] The implementation process of the embodiment of the utility model is as follows: the tobacco shreds conveyed from the previous process fall into the material tightening area formed between the first guide plate 2 and the second guide plate 3 on the vibration trough 1, and under the guiding effect of the inclined first guide plate 2 and the second guide plate 3, the tobacco shreds are tightened in the material tightening area, accompanied by the vibration of the vibration trough 1, the vibration time of the wet bulb and the agglomerated tobacco shreds can be increased, and the wet bulb and the agglomerated tobacco shreds can be preliminarily broken up, and the preliminarily broken up tobacco shreds are mixed with the remaining dispersed tobacco shreds and enter the material dispersing unit 5 through the guide port 4. Under the action of the material dispersing unit 5, the distribution of the tobacco shreds on the vibration trough 1 is changed, thereby improving the uniformity of the tobacco shreds entering the fluidized bed, providing better conditions for the fluidized bed drying of the tobacco shreds, thereby solving the problem of uneven feeding in the vibration trough 1.
