Description

Technical Field

[0001] The utility model relates to the field of tobacco processing, in particular to an electric lifting and loading device for tobacco in a dense curing barn. Background Art

[0002] Tobacco curing is a key step in realizing the economic value of tobacco. The basic process involves placing tobacco leaves on tobacco clips, which are then mounted on racks within the curing barn. Currently, manual loading is the predominant method for attaching the clips to the racks within the curing barn. Loading is a labor-intensive and multi-tasking process. During the tobacco curing season of June and July, tobacco leaves weigh approximately 5,000 kg in a flue-curing barn, typically loaded in three layers: upper, middle, and lower. Loaders work continuously for 3-4 hours in scorching weather to fully load a flue-curing barn. Loading the upper layer of tobacco leaves is particularly challenging, as the tobacco clips are hung 290 cm above the ground and must be hung at a height of at least 160 cm. Due to space constraints within the flue-curing barn, the hangers must constantly adjust the position of the clips mid-air to position them on the hanging beams, a time-consuming and labor-intensive process. During the peak season for tobacco curing, there is a significant imbalance between the total number of tobacco loaders and the demand for tobacco curing personnel. However, under the current intensive baking barn types and baking modes, the mechanical smoke loading devices available in the smoke loading process are relatively complex and sophisticated in structure, with high costs, making them difficult to apply on a large scale. Utility Model Content

[0003] In order to solve the problems of high manual labor intensity in the current smoke loading process and high cost of using mechanical smoke loading devices, the utility model provides a intensive baking barn electric lifting smoke loading device that solves the above problems.

[0004] An electric lifting and smoking device for a dense baking barn comprises a base, a lifting unit and a smoking unit arranged in sequence. The smoking unit is provided with a smoking clamp hanging plane which is a frame structure inclined relative to the horizontal ground.

[0005] In a preferred embodiment of the electric lifting and smoke loading device for a dense baking barn provided by the present invention, the base is a square frame with a width of 50 to 70 cm and an unlimited length.

[0006] The base is parallel to the horizontal ground, and is provided with a plurality of rollers on one side close to the horizontal ground, and the lifting unit is provided on the other side at an angle perpendicular to the base. The rollers are universal wheels with brake devices.

[0007] In a preferred embodiment of the electric lifting and smoke loading device for a dense baking room provided by the present invention, the lifting unit is a single-column electric lift with an external power supply; the chassis of the lifting unit is fixed to the base, and the lifting end is connected to the smoke loading unit.

[0008] In a preferred embodiment of the electric lifting and smoking device for the intensive baking room provided by the present invention, the smoking unit is a right-angled triangle frame, including a strand frame, a hook frame perpendicular to the strand frame, and a chord frame arranged between the two and inclined compared to the horizontal ground.

[0009] The main frame is parallel to the horizontal ground and connected to the lifting end of the lifting unit. The hook frame is perpendicular to the horizontal ground, and the chord frame is inclined relative to the horizontal ground. The main frame width is 115.3-120.6 cm and the length is ≤56 cm; the hook frame width is 42.9-55.5 cm and the length is ≤56 cm; the chord frame width is 128 cm and the length is ≤56 cm. The chord frame is inclined 19.6-25.7 degrees relative to the horizontal ground.

[0010] Compared to existing technologies, the electric lift-loading device for intensive tobacco curing barns provided by this utility model achieves mechanically assisted tobacco loading. This not only reduces the labor intensity of manual tobacco leaf transport and hanging, but also eliminates the need for manual transfer and ladder climbing. No additional personnel are required, and a single person can complete the entire operation, from removing and transporting tobacco leaves to hanging them. Statistics show that the labor efficiency of conventional manual tobacco loading per curing cycle is approximately 399.1 kg per person. However, using the electric lift-loading device for intensive tobacco curing barns provided by this utility model increases the labor efficiency to 1635 kg per person.

[0011] Because the labor intensity of tobacco packing has been significantly reduced and the operation is simple and easy to learn, both men and women with moderate or higher skills can operate independently. This effectively alleviates the current labor shortage constraints of tobacco packing and alleviates the imbalance between labor supply and demand during the tobacco baking period. This helps to slow the trend of tobacco farmers leaving due to the difficulty of hiring workers and alleviate the obstacles to tobacco leaf development caused by labor shortages. At the same time, it can reduce tobacco packing costs and increase tobacco farmers' income. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the electric lifting and smoke loading device of the intensive baking barn. DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0014] See also Figure 1 , is a structural diagram of the electric lifting and smoke loading device 1 for a dense baking barn provided by the present invention. It includes a base 2, a lifting unit 3 and a smoke loading unit 4.

[0015] The base 2 is a square frame welded from hot-dip galvanized square steel pipes with a side length of 60 cm. A plurality of support beams are welded inside the square frame to form a platform for installing the lifting unit 3. The support beams are also made of hot-dip galvanized square steel pipes.

[0016] At the four corners of the bottom of the base 2, there is a universal wheel 21 with a brake device. The universal wheel 21 is used to manually push the electric lifting and loading device 1 of the intensive baking room to move, and is fixed by the brake device during the operation of the loading link.

[0017] The smoke loading unit 4 is a wedge-shaped frame welded with hot-dip galvanized square steel. Two right-angled triangle frames are welded using 128cm, 117.2cm and 51.4cm hot-dip galvanized square steels, and three 56cm long hot-dip galvanized square steel pipes are welded between the vertices of the two. Under the above-mentioned length limit, the chord frame forms an angle of 23.7° with the horizontal ground. From the perspective of the figure, the lower side is recorded as the stock frame, the side is recorded as the hook frame, and the inclined surface is recorded as the chord frame. Two support beams are welded in the middle of the stock frame to form a platform for connecting the lifting end of the single-column electric lift. The support beams are made of the same hot-dip galvanized square steel pipes.

[0018] Lifting unit 3 is a single-post electric lift with a lifting height of 375cm, a load capacity of 185kg, a chassis length and width of 60*60cm, and a mechanical lift rod height of 100cm. It is powered by an external wire. The chassis of the single-post electric lift is welded to the center of base 2, and the lifting end is bolted to the center of the frame.

[0019] The interior space of the smoke-loading chamber of a conventional intensive curing barn is 800cm long, 270cm wide and 350cm high, and is divided into two 135cm wide smoke-loading spaces by smoke-hanging beams in the middle; the smoke-hanging beams are generally divided into three layers, with distances from the ground of 2.9m, 2.1m and 1.3m respectively.

[0020] The tobacco clip used to hold tobacco leaves is 138cm long overall, with a 128cm section in the middle used to hold tobacco leaves, and 5cm of free space left at each end for placement on the tobacco hanging beam.

[0021] Before loading tobacco, the tobacco leaves are first clamped on the tobacco clamps. Then, the four tobacco clamps with tobacco leaves are placed on the string frame of the tobacco loading unit 4 in the electric lifting tobacco loading device 1 of the intensive flue-curing barn, with one end of the tobacco clamp placed higher and the other lower. The electric lifting tobacco loading device 1 of the intensive flue-curing barn with the tobacco clamps and tobacco leaves mounted is pushed and moved into the flue-curing barn.

[0022] During the smoke loading process, first power the lifting unit 3 to the plug, and then adjust the position of the electric lifting smoke loading device 1 of the intensive baking room to ensure that the smoke loading unit 4 and the smoke clamps mounted on it will not scratch the smoke hanging beam or wall during the rising process.

[0023] Control the lifting unit 3 to drive the smoke loading unit 4 and its mounted smoke clamp to the appropriate height, ensuring that the lower end of the smoke clamp is 1-2 cm above the smoke hanging beam where it is to be placed. Then, fine-tune the position of the electric lifting smoke loading device 1 for the intensive curing barn to ensure that the ends of the smoke clamp are directly above the smoke hanging beams on both sides.

[0024] Finally, the lifting unit 3 is controlled to drive the cigarette loading unit 4 and the cigarette clamp mounted thereon to descend. First, the lower side of the cigarette clamp is hung on the cigarette hanging beam on one side. As it continues to descend, the higher side of the cigarette clamp is also hung on the cigarette hanging beam on the other side, completing a set of cigarette loading operations.

[0025] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
