Description

Technical Field

[0001] This utility model belongs to the field of tobacco curing technology, specifically relating to a combination of a tobacco leaf grate box and a curing barn track. Background Technology

[0002] The current standard for intensive tobacco curing barns is 8000 mm long, 2700 mm wide, and 3500 mm high. Three to four layers of tobacco leaves can be hung vertically. Initially, intensive curing barns used hanging poles for loading tobacco, but this was gradually changed to using tobacco clips or loose leaves. In recent years, wire mesh boxes for tobacco curing have also emerged. Figure 1 As shown, two parallel tracks 6 are set on the ground along the length of the curing barn 1. The grate box 5 consists of a square frame composed of three layers of horizontal supports and two rows of vertical supports. There is a certain gap between the first horizontal support 51 at the top of the square frame and the top of the curing barn, which serves as the upwind duct 2. Wheels 7 are installed below the second horizontal support 52 at the bottom of the square frame. A person pushes the grate box along the tracks 6 using the wheels 7. There is a gap between the second horizontal support 52 and the third horizontal support 53 at the bottom of the square frame, which serves as the downwind duct 3. The air in the curing barn can only flow along the downwind duct, the bottom of the grate box to the top of the grate box, and the upwind duct. The bottom of the grate box, within a certain height, serves as the downwind duct, where tobacco leaves cannot be hung. The overall height of the grate box is nearly three meters, while its width is only 50 centimeters, resulting in poor overall stability and a tendency to tip over. Furthermore, a standard dense curing barn can hold 10-30 grate boxes along its length, leading to a significant waste of material in the bottom frame of the grate boxes, creating the downwind duct space. Summary of the Invention

[0003] To address the aforementioned problems in the existing technology, this utility model provides a combination of tobacco leaf grate box and curing barn track.

[0004] The purpose of this utility model is achieved in the following way: a combination of tobacco leaf net box and curing barn track, the net box includes a square frame composed of two layers of horizontal supports and two columns of vertical supports, a walking wheel is provided below the second horizontal support at the bottom of the square frame, curing barn tracks are provided on both side walls along the length of the curing barn, support legs are provided below the curing barn tracks, the curing barn tracks are at least 20cm above the ground, and the walking wheel travels on the curing barn tracks.

[0005] The drying oven track has at least three support legs.

[0006] Three or four layers of tobacco leaves are evenly distributed between the two horizontal supports. Each layer of tobacco leaves is fixed by two rows of pin assemblies. The upper row of pin assemblies is fixed 5-6 cm from the top of the tobacco leaf petiole, and the lower row of pin assemblies is fixed 22-25 cm from the top of the tobacco leaf petiole. Alternatively, tobacco leaves are scattered between the two horizontal supports and fixed by 5-8 rows of pin assemblies. Each row of pin assemblies is evenly distributed between the two horizontal supports.

[0007] Multiple pin assembly fixing holes are distributed on the opposite surfaces of the two vertical supports in the same row. Two pin assembly fixing holes at the same horizontal height on the two vertical supports are grouped together. A row of pin assemblies is fixed in a group of pin assembly fixing holes. Multiple pin support beams are set on the other row of vertical supports without pin assembly fixing holes. The number of pin support beams corresponds to the number of groups of pin assembly fixing holes.

[0008] Multiple pin assembly fixing holes on the same vertical support are arranged at equal or unequal intervals.

[0009] The pin assembly includes a crossbar and a row of pins evenly fixed on the crossbar. Both ends of the crossbar are provided with pin mechanisms. The pin mechanisms are inserted into the fixing holes of the pin assembly to connect the pin assembly to the vertical support. The ends of the pins are supported on the pin support beam.

[0010] Compared to existing technologies, this invention raises the two tracks inside the drying room from the ground via support legs, reducing the overall height of the grate without changing the amount of smoke it can hold, improving its stability, saving material on the bottom frame, and reducing costs.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various modifications or alterations to the present invention, and these equivalent forms also fall within the scope defined by the present invention.

[0016] like Figure 2 , Figure 3As shown, a combination of tobacco leaf netting and curing barn track is provided. The netting 5 includes a square frame consisting of two layers of horizontal supports and two rows of vertical supports. A traveling wheel 7 is provided below the second horizontal support 52 at the bottom of the square frame. Curing barn tracks 6 are provided on both side walls along the length of the curing barn. Support legs 9 are provided below the curing barn tracks 6. The curing barn tracks 6 are at least 20cm above the ground, preferably 20-50cm. The traveling wheel 7 travels on the curing barn tracks 6.

[0017] This invention raises two tracks inside the curing barn from the ground, saving one horizontal support and one vertical support between the two horizontal supports at the bottom of each wire mesh box. A curing barn can accommodate 10-30 wire mesh boxes, saving even more materials. Furthermore, raising the two tracks 20-50cm upwards via a few support legs incurs minimal cost, resulting in significant cost savings compared to other methods. More importantly, without changing the amount of tobacco loaded into the wire mesh box, the overall height of the box is reduced, improving its stability.

[0018] A further optimized design includes at least three support legs 9. The curing barn track 6 is preferably made of U-shaped steel, and the support legs 9 are preferably made of square steel. The support legs 9 are welded and fixed to the curing barn track 6, providing support and making the track 6 more stable. The weight of the grate and tobacco leaves is directly distributed to the ground through the curing barn track 6 and support legs 9, without putting pressure on the side walls of the curing barn. Considering both the strength of the curing barn track 6 and the weight of the grate and tobacco leaves, the number of support legs can be adjusted. With a curing barn length of 8 meters and a grate width of 50cm, approximately 16 grate boxes are arranged along the length. In this case, 8-10 support legs 9 are preferred. If the width of the grate increases or decreases, the number of grate boxes arranged in the curing barn will change accordingly; the number of support legs can then be adjusted.

[0019] Furthermore, three or four layers of tobacco leaves are fixed between the two horizontal supports. Each layer of tobacco leaves is fixed by two rows of pin assemblies 8. The upper row of pin assemblies 8 is fixed 5-6 cm from the top of the tobacco leaf petiole, and the lower row of pin assemblies 8 is fixed 22-25 cm from the top of the tobacco leaf petiole. Alternatively, tobacco leaves are scattered between the two horizontal supports and fixed by 5-8 rows of pin assemblies 8, with each row of pin assemblies 8 evenly distributed between the two horizontal supports.

[0020] Furthermore, such as Figure 4 As shown, multiple pin assembly fixing holes 10 are distributed on the opposite surfaces of the two vertical supports in the same row. Two pin assembly fixing holes 10 at the same horizontal height on the two vertical supports 53 form a group. A row of pin assemblies 8 is fixed in a group of pin assembly fixing holes 10. Multiple pin support beams are provided on the other row of vertical supports without pin assembly fixing holes 10. The number of pin support beams corresponds to the number of groups of pin assembly fixing holes 10. The multiple pin assembly fixing holes 10 on the same vertical support are arranged at equal intervals or non-equal intervals.

[0021] The pin assembly 8 includes a crossbar 81 and a row of pins 82 evenly fixed on the crossbar. Both ends of the crossbar are provided with pin mechanisms 83. The pin mechanisms 83 are inserted into the pin assembly fixing holes 10 to connect the pin assembly 8 to the vertical support 53. The ends of the pins are supported on the pin support beam (not shown in the figure).

[0022] The pin insertion assembly 8 can be inserted using an automatic pin insertion machine, which improves insertion efficiency compared to inserting individual pins into tobacco leaves one by one in the prior art. Compared to the U-shaped pin in Chinese Patent Application No. 201520825591.6, the split two-row pin insertion assembly has less insertion resistance, and the gap between the two rows of pin insertion assemblies can be adjusted according to the size of the tobacco leaves, resulting in better fixing effect.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
