TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco leaf curing equipment, in particular to a high-layer tobacco rack structure of a tobacco leaf curing barn. BACKGROUND

[0002] The curing of flue-cured tobacco is different from the curing of air-cured tobacco. The curing of flue-cured tobacco mainly utilizes the hot air in the curing barn to remove the moisture from fresh tobacco leaves and to transform the chemical components in the tobacco leaves. In order to ensure the curing quantity of tobacco leaves, the existing curing barns are provided with multiple curing racks from top to bottom to realize the hanging and curing of 3-4 layers of tobacco leaves at the same time. That is, the existing technology is to hang the two ends of the carrier (tobacco rod or tobacco clamp) on two curing racks at the same height after the tobacco leaves are baled (carrier is tobacco rod) or clamped (carrier is tobacco clamp), and then to complete the hanging of 3-4 layers of tobacco leaves from top to bottom. This requires the workers to move from the inside to the outside of the curing barn and repeatedly climb up to realize the hanging of the high-layer tobacco leaves. Moreover, the space inside the curing barn is narrow and cramped, the overall operation is very complicated, and the spacing between the tobacco leaves cannot be uniformly arranged, which leads to poor flow of hot air in the later stage, and thus affects the heating and moisture removal effects of the tobacco leaves.

[0012] Preferably, the connecting assembly comprises a plurality of connecting plates arranged in the cavity, the connecting plates span two adjacent pitch adjustment sliding seats, and the connecting plates and the positioning boxes on the pitch adjustment sliding seats are arranged in a staggered manner.

[0013] The positioning box of the pitch adjustment sliding seat at the end of the interior of the drying room is provided with a positioning rod, and the positioning boxes of the remaining pitch adjustment sliding seats are provided with connecting rods sequentially penetrating the positioning boxes and the corresponding connecting plates.

[0014] The end of the positioning rod and the connecting rod away from the end of the positioning box is provided with a flange, and the cavity of the pitch adjustment frame is further provided with a limiting sliding groove matched with the flange in a gap.

[0015] Preferably, a connecting long hole for slidingly cooperating with the connecting rod is arranged on the plate body of the connecting plate, and a positioning long hole for slidingly cooperating with the connecting rod or the positioning rod is arranged on the box body of the positioning box.

[0016] When the pitch adjustment sliding seats are in contact with each other, the connecting long hole of the connecting plate coincides with the positioning long hole of the corresponding pitch adjustment sliding seat positioning box, and the distance between the positioning rod and the adjacent connecting rod and the distance between the connecting rods are the same.

[0017] One end of the connecting plate towards the interior of the drying room is fixedly connected with the end of the adjacent pitch adjustment sliding seat positioning box towards the outside, and the other end is free and slidingly cooperates with the corresponding connecting rod.

[0018] Preferably, the end of the positioning rod and the connecting rod away from the flange is coaxially provided with a positioning disc located in the positioning box, and the top surface and the bottom surface of the positioning box are both provided with a positioning groove for cooperating with the positioning disc, and the disc surface of the positioning disc is exposed from the positioning groove to the cavity.

[0021] Preferably, the end of the distance adjusting frame facing the outside world is provided with a notch through which the adjusting rod is inserted, and the end of the adjusting rod exposed to the outside world is provided with a length scale.

[0022] The working process of the present application is as follows:

[0023] Firstly, the present application is in an initial state before loading the tobacco, that is, the distance adjusting slides are in contact with each other and located at the end of the distance adjusting frame facing the outside world, and the driving slides are in contact with each other and located at the end of the driving frame facing the outside world, at this moment, the adjusting rod is located below the positioning rod and the connecting rod and keeps separated from the positioning rod and the connecting rod. Then the staff climbs at the door of the curing barn to load the tobacco, and embeds the two ends of the tobacco rod after rolling tobacco or the tobacco clamp after clamping tobacco leaves into the corresponding grooves of the distance adjusting slides and the driving slides until all the tobacco loading actions are completed.

[0024] After the manual loading of tobacco is completed, the staff returns to the ground and starts the motor to drive the lead screw to rotate forward, the lead screw drives the driving block at the end of the inside direction of the curing barn through the screw thread sleeve to move along the driving frame towards the inside of the curing barn, and at the same time, the driving slide moves the corresponding distance adjusting slide (i.e. the distance adjusting slide provided with the positioning rod) and the connecting plate fixedly connected thereto in a synchronous manner through the corresponding tobacco rod or tobacco clamp. When the connecting plate of the distance adjusting slide moves to the inside wall of the connecting hole in contact with the connecting rod of the adjacent distance adjusting slide, it will pull the connecting rod and the corresponding distance adjusting slide to continue moving, and at the same time, it will also drive the corresponding driving slide to move synchronously through the tobacco rod or tobacco clamp, so that all the distance adjusting slides and driving slides are arranged at equal distances in sequence.

[0025] After the curing and re-humidification are completed, the door of the curing barn is opened, the motor is started to drive the lead screw to rotate reversely, the lead screw drives the driving block at the end of the inside direction of the curing barn through the screw thread sleeve to move along the driving frame towards the outside of the curing barn, and at the same time, the driving slide moves the corresponding distance adjusting slide (i.e. the distance adjusting slide provided with the positioning rod) and the connecting plate fixedly connected thereto in a synchronous manner, and in the subsequent movement process, it sequentially touches and pushes the adjacent distance adjusting slide and driving slide to the initial state, and the staff can unload the tobacco at the door of the curing barn.

[0026] Due to the differences in width, thickness and other agronomic characteristics of different varieties and different parts of tobacco leaves in actual curing operation, the distance between the tobacco leaves in the curing barn needs to be adjusted to meet the uniformity of hot air distribution and the effective moisture removal process requirements of the tobacco leaves in the yellowing stage during the conditioning process. Therefore, the present application can change the distance between the adjacent driving slides and the adjacent distance adjusting slides after loading the tobacco by the following operations:

[0027] First, the driving slide and the distance adjustment slide are adjusted to the initial state, in which the clamping seat on the adjusting rod can correspond to the positioning rod and the connecting rod of each distance adjustment slide; then the adjusting rod is lifted along the gap, so that the clamping seat of the adjusting rod can be clamped on the corresponding positioning rod and connecting rod above, and the positioning rod and the connecting rod are moved upwards to move out of the gap of the positioning protrusion in the corresponding positioning long hole. Then the adjusting rod is moved horizontally outward or inward, so that the positioning rod and the connecting rod move upwards inside the positioning long hole and the connecting long hole, and the distance between the end of the connecting long hole of the corresponding connecting plate is changed, then the adjusting rod is moved downwards, and the adjusting rod falls into the positioning protrusion groove below, thereby finally realizing the maximum distance adjustment of the adjacent distance adjustment slide.

[0028] Compared with the prior art, the present application has the following advantages:

[0029] 1) The present application has a simple structure, which can effectively realize the equidistant arrangement of the tobacco carriers in the curing barn, and the loading and unloading operations of the tobacco carriers in the curing barn can be performed at the door of the curing barn, so that the operation space is larger.

[0030] 2) The present application can adjust the distance between adjacent tobacco carriers according to the width, thickness and other agronomic characteristics of the tobacco to be cured, thereby adjusting the density of the tobacco in the curing barn and improving the flowability of the hot air flow in the curing barn.
