Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tobacco curing equipment, and in particular to a rapid loading and unloading device for tobacco curing. Background Technology
[0002] After the tobacco leaves are stalked, they need to be placed on the drying rack in the tobacco loading chamber of the curing barn for curing. After curing, they need to be removed from the drying rack. Currently, the standard size of a dense curing barn is generally 8m × 2.7m × 3.5m (length × width × height). The second and top layers of tobacco hanging racks are quite high, making it impossible for tobacco farmers to move up and down the drying racks while standing on the floor of the loading chamber. There are two existing methods for moving tobacco up and down the drying racks: one is for farmers to climb the hanging racks, where one person stands on the rack and another person stands on the ground to pass tobacco between them. This method is labor-intensive, costly, and poses safety hazards. The other method is to use mechanical equipment to move tobacco up and down the drying racks, where the equipment passes tobacco from one stalk to another, but this method is also inefficient. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a device for rapid loading and unloading of tobacco in the curing process, so as to solve the technical problems mentioned in the background art.
[0004] The objective of this utility model is achieved through the following technical solution: The rapid loading and unloading device for flue-cured tobacco includes three rows of columns positioned near the two side walls and the middle of the tobacco loading chamber. The three rows of columns provide fixed support for a bottom-level tobacco hanging rack. A middle-level tobacco hanging rack and a top-level tobacco hanging rack are movably mounted on the three rows of columns. The middle-level and top-level tobacco hanging racks are respectively fixedly connected to the three rows of columns via connectors. The device also includes a rope winding and unwinding mechanism located within the tobacco loading chamber. The rope winding and unwinding mechanism has at least one set of pulling ropes. At least one set of pulleys is located at the top of the tobacco loading chamber. The at least one set of pulling ropes passes around the at least one set of pulleys and connects to the middle-level or top-level tobacco hanging rack.
[0005] Furthermore, the rope winding and unwinding mechanism includes a rotating mechanism and a rotating shaft. The rotating shaft is vertically mounted on the smoke chamber door, and the rotating mechanism drives the rotating shaft to rotate.
[0006] Furthermore, the bottom, middle, and top smoke racks each include three smoke beams, which are connected to three rows of columns respectively. Each set of pull ropes includes three pull ropes, and each set of pulleys includes three sets of pulleys. Each set of three pull ropes passes around each set of three sets of pulleys and connects to the three smoke beams of the middle smoke rack or the three smoke beams of the top smoke rack.
[0007] Furthermore, in each set of three pulleys, one pulley consists of one pulley located in the middle of the smoke loading chamber, while the other two pulleys each consist of two pulleys. In the other two pulleys, one pulley is located in the middle of the smoke loading chamber, and the other pulley is located near the side walls of the smoke loading chamber.
[0008] Furthermore, the smoke beams on the two rows of columns near the sides of the smoke loading chamber are made of angle steel, with one side of the angle steel parallel to the column. The smoke beams on the row of columns in the middle of the smoke loading chamber are made of channel steel, with the web of the channel steel perpendicular to the column.
[0009] Furthermore, the middle and top layer cigarette racks are provided with ball bearing sleeves on the side of the angle steel parallel to the column, and the web of the channel steel is provided with ball bearing sleeves vertically, and the ball bearing sleeves are sleeved on the column.
[0010] The beneficial effects of this utility model are: The rapid loading and unloading device for flue-cured tobacco proposed in this utility model allows tobacco farmers to load tobacco onto the top-level tobacco rack while standing on the floor of the tobacco loading chamber. Once the top-level rack is full, the end of the pull rope is connected to the rack, and the pull rope is pulled through a rope retraction mechanism to move the top-level rack to a set position (the existing height of the top-level rack within the loading chamber). It is then fixed to the three rows of uprights via connectors. The device also allows farmers to load tobacco onto the middle-level tobacco rack while standing on the floor of the loading chamber. Once the middle-level rack is full, the end of the pull rope is connected to the rack, and the pull rope is pulled through a rope retraction mechanism to move the middle-level rack to a set position (the existing height of the middle-level rack within the loading chamber). The device can be fixed to the three rows of uprights via connectors. Connect the end of the pull rope to the middle-level tobacco rack, disconnect the middle-level tobacco rack from the three rows of uprights, and slowly release the pull rope using the rope retraction mechanism to lower the middle-level tobacco rack to a position accessible to the tobacco farmer standing on the ground of the tobacco loading chamber. Then, lower the tobacco from the middle-level tobacco rack. Connect the end of the pull rope to the top-level tobacco rack, disconnect the top-level tobacco rack from the three rows of uprights, and slowly release the pull rope using the rope retraction mechanism to lower the top-level tobacco rack to a position accessible to the tobacco farmer standing on the ground of the tobacco loading chamber. Then, lower the tobacco from the top-level tobacco rack. This device allows multiple people to simultaneously load and unload tobacco from the top-level or middle-level tobacco racks, resulting in high efficiency, low labor intensity, and reduced safety hazards.

Each set of three pulleys 9 passes over each set of three pulleys 10 and connects to the three smoke beams 5 of the middle-layer smoke rack 3 or the three smoke beams 5 of the top-layer smoke rack 4. The pulleys 9 are connected to the smoke beams 5 by passing through holes in the beams and connecting to wire rope clips. The holes on the middle-layer and top-layer smoke racks correspond, and the pulleys pass through the holes on the top-layer rack when connecting to the middle-layer rack. One end of each set of three pulleys can be connected to a main pulley, which is wound around a rotating shaft.
[0018] When this device is used for loading tobacco onto the loading bed, the middle-layer tobacco rack 3 and the top-layer tobacco rack 4 are first lowered to a position that the tobacco farmer can reach from the ground of the loading chamber. Then, tobacco is loaded onto the top-layer tobacco rack 4. After it is full, the ends of the three pull ropes 9 in each group are connected to the top-layer tobacco rack 4. The rope retraction mechanism is activated to retract the pull ropes 9, which pull the top-layer tobacco rack 4 upward. When the top-layer tobacco rack 4 reaches the set position (the set position here is the existing height of the top-layer tobacco rack in the loading chamber), it is connected using a connector. Then, tobacco is loaded onto the middle-layer tobacco rack 3. After it is full, the ends of the three pull ropes 9 in each group are connected to the middle-layer tobacco rack 3. The rope retraction mechanism is activated to retract the pull ropes 9, which pull the middle-layer tobacco rack 3 upward. When the middle-layer tobacco rack 3 reaches the set position (the set position here is the existing height of the middle-layer tobacco rack in the loading chamber), it is connected using a connector. Finally, tobacco is loaded onto the bottom-layer tobacco rack 2.
[0019] When using this device to unload tobacco from the tobacco drying rack, first unload the tobacco from the bottom layer tobacco rack 2, then connect the ends of the three pull ropes 9 in each group to the middle layer tobacco rack 3, disconnect the connection between the middle layer tobacco rack 3 and the three rows of uprights 1, start the rope retraction mechanism, and slowly release the pull ropes 9 to lower the middle layer tobacco rack 3 to a position that the tobacco farmer can reach from the ground of the tobacco loading chamber, then unload the tobacco from the middle layer tobacco rack 3.
