1-3, the utility model provides a sealed tobacco shred lifting device, which comprises a lifting machine 1 and a sealing assembly. The hoisting machine 1 can be divided into a horizontal transfer section 11, a transition section 12 and a lifting section 13 according to the location and function. The horizontal conveying section 11 is used for conveying tobacco in the horizontal direction, has a short length, and is mainly used for receiving falling cut tobacco and carrying out next conveying. The lifting section 13 is used for lifting the cut tobacco from a lower position to a cut tobacco dryer inlet at a higher position. The transition section 12 is used for connecting the horizontal conveying section 11 and the lifting section 13, so that the cut tobacco can be transported smoothly. The seal assembly 2 comprises a first seal 21 arranged over the whole section of the lifting section 13, a second seal 22 arranged at the transition section 12 and a third seal 23 arranged at the conveying end of the lifting section 13.

The conveyor belt surface is provided with a plurality of rows of uniformly arranged rake finger assemblies 25. The rake teeth assembly 25 is used for driving the cut tobacco to ascend and drive. The tine assembly 25 includes a mounting seat 251 fixedly provided on the surface of the conveyor belt and tines 252 disposed in the opposite direction of the depth of the side plate 14 in the direction of the surface of the mounting seat 251. The arrangement direction of the rake teeth 252 is arranged along the length direction of the mount 251 and equidistantly. The length of the mounting seat 251 is set in accordance with the width direction of the conveyor belt. Both ends of the mount 251 are partially covered by guide plates 15 (described in detail below).

The first seal 21 is mainly used to prevent the cut tobacco from falling partially into the gap between the side plate 14 and the conveyor belt during the lifting process. Specifically, the hoist 1 integrally includes a conveyor belt and side plates 14 provided on both sides of the conveyor belt. The side plates 14 are provided with guide plates 15 on the side close to the conveyor belt. It is worth noting that the guiding plates 15 may be provided only on the corresponding side plates 14 of the lifting section 13, so that the tobacco is lowered into the gap between the side plates 14 and the conveyor belt during lifting. The cross-sectional area of the guide plate 15 linearly decreases in the depth direction of the side plate 14. The guide plate 15 may have a slope or a smooth arc surface. The guide plate 15 is used for guiding the tobacco shreds towards the middle of the conveyor belt, so that the tobacco shreds are far away from the side plates 14 at the two ends as much as possible. In this way, the risk of tobacco shreds entering the gap between the side plates 14 and the conveyor belt is reduced. A gap is reserved between the guide plate 15 and the conveyor belt for the conveyor belt and the mounting seat to pass through. The guide plate 15 is provided with a first seal 21 on the side that matches the conveyor belt. The first seal 21 is arranged along the length direction of the guide plate 15. The first seal 21 is disposed along the length of the side plate 14 in the depth direction in cooperation with the height of the slit. The first seal 21 may be a brush or a flexible sheet with elastic deformation capability, which allows the passage of the mounting seat 251 and keeps the slit isolated from the cut tobacco on the conveyor belt.

A second seal 22 is provided at the transition section 12 for smooth connection of the side plates 14 of the horizontal transfer section 11 and the side plates of the lifting section 13. The connecting mode is different from the existing connecting mode of the side plates of the horizontal conveying section 11 and the lifting section 13, the existing connecting mode is linear connection and basically is a linear corner, and the connecting position between the transition section 12 and the side plate 14 is not easy to seal due to the fact that the corners of the connecting position are more. The second seal 22 is an arcuate plate that is form-fit to the transition section 12. The second seals 22 can smoothly connect the side plates of the horizontal transfer section 11 and the lifting section 13. In this way, the provision of the relevant sealing means of the transition piece 12 is facilitated.

A third seal 23 is provided at the lifting end of the lifting section 13 for scraping off the cut tobacco that has adhered to the tines 252 after the completed transport of the tobacco, thereby reducing the drop of cut tobacco into the conveyor belt interlayer. The third seal 23 includes a stop plate 24 with one end proximate the conveyor belt. The limiting plate 24 is maintained in the working condition position by welding, lapping or the like. The limiting plate 24 is provided with a limiting hole 241 with a position and a shape matched with the rake teeth 252, so that when the rake teeth 252 pass through the limiting hole 241, cut tobacco attached to the rake teeth 252 can be scraped off by the limiting plate 24.

The third seal 23 may also be a brush placed in the working position for brushing down excess cut tobacco that is attached to the tines 252 and falls into the cut tobacco dryer below the transport end of the conveyor. Therefore, the tobacco quantity in the interlayer falling into the lower part of the conveyor belt can be reduced, the tobacco loss is reduced, the quantity of tobacco falling into the elevator from the positions of the clearance between the conveyor belt and the side plate piece, the tail end of the conveying direction and the like is reduced, the part loss of the elevator is optimized to a certain extent, and the cost of the tobacco in the manufacturing process is saved.

According to the utility model, the first sealing element 21 is arranged on the whole lifting section 13 to prevent tobacco from entering a gap between the side plate 14 and the conveyor belt, the arc-shaped sealing assembly is arranged on the transition section 12 to facilitate the sealing measure installation, the third sealing element 23 for cleaning the rake teeth 252 is arranged at the tail end of the conveying direction of the lifting section 13 to prevent tobacco shreds attached to the rake teeth 252 from falling into the interlayer of the lifter.
