Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco production, and particularly relates to a tobacco drying steel frame drying room. Background Art

[0002] As a traditional tobacco curing method, air-drying tobacco has a long history and is widely used in my country. The traditional air-drying process usually uses the 89-type air-drying room to adjust the tobacco leaves. However, with the development of technology and changes in social needs, this traditional air-drying method faces many challenges, among which the main problems include:

[0003] 1. Due to the shortage of agricultural land resources, it is strictly forbidden to occupy permanent basic farmland to build planting facilities that destroy the arable layer, resulting in strict restrictions on the promotion of the 89-style drying room;

[0004] 2. The existing 89-style drying room roofs are mostly made of cement tiles or colored steel tiles, which are not airtight enough all around, making it difficult to maintain internal humidity and effectively discharge excess moisture;

[0005] 3. When encountering unfavorable climatic conditions such as low temperature and high humidity or high temperature and low humidity, it is easy to cause tobacco leaves to rot in the shed (too wet) or dry quickly (too dry), affecting the quality of tobacco leaves;

[0006] 4. Since the Type 89 drying room cannot make full use of natural light, its internal temperature is relatively low, which makes the tobacco leaf drying process slow, especially the drying stage, which takes a long time.

[0007] In response to the above defects, the current conventional solution is to use coal, firewood or other biomass fuel particles as a heat source to increase the curing temperature and shorten the curing time, or after the tobacco leaves are harvested, first place them in a drying shed to quickly lose water and wither, then move them to the tobacco drying shed to complete the yellowing and browning stages of curing, and finally move them back to the drying shed to complete the dry rib stage. However, the above method is not accurate enough in temperature control, which can easily destroy the unique quality and flavor of air-dried tobacco, and increases labor costs. The tobacco leaves are easily damaged during multiple moves, and additional drying shed space is required, further exacerbating the tension of land resources. Summary of the invention

[0008] In view of the technical problems existing in the background technology, the utility model proposes a steel frame drying room for drying tobacco, which has a simple structure and is easy to build, so that tobacco leaves can be dried, air-dried and dried in the same shed. By using this tobacco drying shed, the curing time can be greatly shortened, the input cost and labor of tobacco farmers can be reduced, and the benefits of tobacco farmers can be improved.

[0009] In order to solve the above technical problems, the utility model adopts the following technical solutions to achieve:

The columns are vertically inserted into the ground and arranged side by side. Cross beams are vertically connected in the lateral direction of the columns, and shoulder beams are vertically connected in the longitudinal direction of the columns. Top beams are arranged in parallel between the lateral columns. The top beams are arranged at the midline position of the columns and above the columns. Arch rods are inserted between the two side shoulder beams and the top beam. Suspender rods are connected between the two ends of the top beam and the cross beam. The outer sides of the columns, shoulder beams, cross beams and arch rods are covered with shed films.

[0011] In a preferred embodiment, the columns, shoulder beams and cross beams are vertically inserted into each other through first sleeves.

[0012] In a preferred embodiment, the shoulder beams and arch rods are vertically inserted into each other through second sleeves.

[0013] In a preferred embodiment, drain grooves are provided on the outer sides of the columns, and the ends of the drain grooves are communicated with drain pipes.

[0014] In a preferred embodiment, rolling curtains are installed between the two end columns. Clasps are installed on the rolling curtains, and snap rings are installed on the ground below the rolling curtains. The rolling curtains are snap-connected through the clasps and the snap rings.

[0015] In a preferred embodiment, a clamping mechanism is installed on the side wall of the shoulder beam and is detachably connected to the shed film.

[0016] In a preferred embodiment, the clamping mechanism comprises a base, a clamping plate, a telescopic rod, a compression spring and a side plate. The base is fixedly connected to the side wall of the shoulder beam. A side plate is vertically connected to the lower end of the base. The telescopic rod passes through the base and the side plate and can slide along the axis with limited movement. A clamping plate is vertically connected to the end of the telescopic rod. A compression spring is sleeved on the outer wall of the telescopic rod, and the two ends of the compression spring are respectively connected to the side plate and the inner wall of the base.

[0017] A tobacco-curing steel-frame curing barn has the following beneficial effects during actual use:

[0018] 1. The steel-frame curing barn can be appropriately adjusted in length according to the characteristics of mountainous terrain, increasing the applicable range of the curing barn. The detachable design enables it to move flexibly and be reused between different seasons or locations;

The top beam 5 is arranged at the midline position of the column 1 and above the column 1. An arch rod 4 is inserted between the two side shoulder beams 2 and the top beam 5. A hanging rod 6 is connected between the two ends of the top beam 5 and the cross beam 3. The outside of the column 1, the shoulder beam 2, the cross beam 3 and the arch rod 4 is covered with a shed film 14;

[0031] During the actual construction of the curing barn, all its components are built with steel structures. The column 1 is usually set with a span of 4 meters, a column spacing of 2 meters, the spacing of the shoulder beams 2 is usually set at 2 meters, the top height of the arch rod is usually set at 2.9 meters, the arch spacing is 1 meter, and the span is 4 meters. Hexagon self-drilling screws are installed on the shoulder beam 2 every 10 cm for pulling curing ropes between two parallel shoulder beams;

[0032] The 6 parts of the hanging rod are connected to the top beam 5 through T-shaped duckbill clamps and bolts, and the lower part is connected to the end cross beam 2 through circular clamps and bolts. By adopting the above-mentioned building method, the drying house can be used under different terrain conditions, and at the same time, it can provide good ventilation, heat preservation and moisture-proof performance.

[0033] The preferred scheme is as Figure 4 and Figure 5 shown. The column 1, the shoulder beam 2 and the cross beam 3 are vertically inserted through the first sleeve 12; the shoulder beam 2 and the arch rod 4 are vertically inserted through the second sleeve 13. By adopting the above structure, the column 1, the shoulder beam 2, the cross beam 3 and the arch rod 4 can be quickly disassembled and connected, improving the building efficiency of the drying house and the reuse rate of materials.

[0034] The preferred scheme is as Figure 1 and Figure 3 shown. A rolling curtain 7 is installed between the columns 1 at both ends. A buckle 701 is installed on the rolling curtain 7, and a snap ring 8 is installed on the ground below the rolling curtain 7. The rolling curtain 7 is clamped with the snap ring 8 through the buckle 701. Through the above structure, the shed films at both ends of the drying house can be pulled up and down at any time, facilitating the adjustment of the ventilation volume to meet different requirements during the tobacco leaf drying process.

[0035] The preferred scheme is as Figure 1 and Figure 6 shown. A clamping mechanism 9 is installed on the side wall of the shoulder beam 2 and is detachably connected to the shed film 14; the clamping mechanism 9 includes a base 901, a clamping plate 902, a telescopic rod 903, a compression spring 904 and a side plate 905.

A clamping plate 902 is vertically connected to the end of the telescopic rod 903. A compression spring 904 is sleeved on the outer wall of the telescopic rod 903. The two ends of the compression spring 904 are respectively connected to the side plate 905 and the inner wall of the base 901;

[0036] After the heat preservation films on the top and side of the drying house are laid, the clamping plate 902 can be pulled outwards, and the end of the heat preservation film is placed between the clamping plate 902 and the base 901. Then, the clamping plate 902 is released. Under the action of the compression spring 904, the clamping plate 902 will move inwards and jointly clamp the heat preservation film with the outside of the base 901 to complete the fixing work of the heat preservation film. By adopting the above structure, the heat preservation film can be quickly installed and disassembled, facilitating the subsequent maintenance and replacement of the greenhouse.
