Description

Technical Field

[0001] This utility model belongs to the field of tobacco leaf processing technology, and in particular relates to a self-propelled tobacco curing barn lifting machine. Background Technology

[0002] The appearance quality of tobacco leaves refers to the quality factors that people can judge through their senses, usually by sight, touch, hearing, and smell. The appearance quality factors closely related to curing mainly include six aspects: color, chroma, oil content, identity, damage, and breakage. During the curing process, during the yellowing stage, a series of high-molecular-weight substances decompose into smaller molecules, forming the original aroma substances of the tobacco leaf; during the color-fixing stage, the original aroma substances dehydrate and condense, forming aroma compounds; during the drying stage, some aroma compounds decompose and volatilize, especially under high-temperature conditions above 68℃, where a significant amount of aroma compounds volatilize. The entire tobacco curing process fixes, presents, and enhances the quality of fresh tobacco leaves, forming the overall smoking quality of the first-cured tobacco leaves.

[0003] When tobacco leaves are cured, they need to be arranged sequentially on the curing supports before being transported to the curing barn, requiring transfer. Existing curing supports come in various lengths, while the existing transfer racks are fixed in size. These fixed-size transfer racks cannot accommodate supports of different lengths, potentially causing supports to be unstable or not fully loaded, necessitating repeated adjustments or even replacement of the transfer equipment, thus extending transfer time. If the transfer rack is smaller than the support length, it may only be able to load a portion of the supports, or inefficient space utilization may reduce the amount transferred per batch, requiring more transfers and lowering overall efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The following, in conjunction with the accompanying drawings, details the technical solution of a self-propelled tobacco curing barn lifting machine provided by various embodiments of this utility model.

[0023] Reference Figures 1 to 6 As shown, this utility model embodiment provides a self-propelled tobacco curing barn lifting machine, including a self-propelled tracked machine 1 and a hydraulic lift 2. The hydraulic lift 2 is mounted on the self-propelled tracked machine 1. The hydraulic lift 2 is provided with a horizontally arranged mounting plate 3. The mounting plate 3 is provided with a horizontally arranged extension plate 31. The extension plate 31 is slidably engaged with the mounting plate 3. The mounting plate 3 and the extension plate 31 are provided with four transfer frames 4. The four transfer frames 4 are rectangularly distributed on the top of the mounting plate 3 and the extension plate 31. Two fixing rods 5 are provided between two adjacent transfer frames 4. Several tobacco curing supports 6 are provided between two adjacent transfer frames 4. The two ends of the tobacco curing supports 6 are respectively placed on the transfer frames 4.

[0024] The hydraulic lift 2 is prior art, as can be found in Chinese Patent Publication No. CN211846997U. The self-propelled tracked machine 1 is also prior art. During the transfer of tobacco leaves, the self-propelled tracked machine 1 can transport the tobacco leaves to the tobacco curing barn. The hydraulic lift 2 can adjust the vertical position of the tobacco leaves. When placing the tobacco leaves on the curing fixture into the tobacco curing barn for curing, the worker can stand on the mounting plate 3. Then, the tobacco curing supports 6 on the two transfer frames 4 are moved into the tobacco curing barn. The hydraulic lift 2 can raise and lower the worker's position, swinging the tobacco leaves in the tobacco curing barn for curing.

[0025] Specifically, the transfer frame 4 is provided with several equally spaced diagonal bars 41, and a placement space 42 for placing the tobacco curing support 6 is provided between the diagonal bars 41 and the transfer frame 4. The bottom of the transfer frame 4 is provided with four mounting holes 43. The mounting holes 43 at the bottom of the transfer frame 4 can be bolted to the connecting holes 33 on the slider 32, thereby fixing the position of the transfer frame 4.

[0026] When transferring tobacco leaves, the two ends of the tobacco curing support 6 are placed in the corresponding two placement spaces 42 respectively. With several inclined rods 41 and several placement spaces 42, multiple tobacco curing supports 6 can be placed during the tobacco leaf transfer process, thereby enabling a larger number of tobacco leaves to be transferred at one time, thus improving the efficiency of the transfer.

[0027] Specifically, the fixing rod 5 includes a first connecting rod 51 and a second connecting rod 52. One end of the first connecting rod 51 is fixedly connected to one of the transfer frames 4, and the second connecting rod 52 is fixedly connected to the other transfer frame 4. The first connecting rod 51 and the second connecting rod 52 are interlocked. The second connecting rod 52 is provided with a plurality of equally spaced insertion holes 53, and a fixing pin 54 is provided between the first connecting rod 51 and the insertion holes 53. The fixing rod 5 can pull and fix the positions of two adjacent transfer frames 4, thereby fixing the position of the transfer frames 4.

[0028] Specifically, the top of the extension plate 31 is provided with two sliders 32, the top of the sliders 32 is flush with the top of the mounting plate 3, each slider 32 is provided with several sets of equally spaced connecting holes 33, and the two end side walls of the mounting plate 3 are provided with locking screws 34, which lock and fix the position of the extension plate 31.

[0029] During the transfer of tobacco leaves, the length of the extension plate 31 can be adjusted according to the length of the flue-curing support 6. When facing a shorter flue-curing support 6, the ends of the mounting plate 3 and the extension plate 31 are flush, and the mounting hole 43 on the transfer frame 4 can be connected to the corresponding connection hole 33 on the slider 32.

[0030] When dealing with a long tobacco curing support 6, the extension plate 31 can be moved outward from the mounting plate 3. After the two transfer frames 4 are moved outward to the length corresponding to the tobacco curing support 6, the two locking screws 34 are rotated to lock the position of the extension plate 31 on the mounting plate 3. When the extension plate 31 moves outward, the pin 54 is pushed outward, which allows the second connecting rod 52 to move outward from the first connecting rod 51. This makes the lengths of the first connecting rod 51 and the second connecting rod 52 match the width between the two transfer frames 4. Then, the pin 54 is inserted into the insertion hole 53 in the second connecting rod 52 to lock and fix the first connecting rod 51 and the second connecting rod 52.

[0031] During the transfer of tobacco leaves, the spacing and distance between the two transfer frames 4 can be adjusted according to the different sizes of the flue-cured tobacco support 6. The adjustable spacing of the transfer frames 4 can cover flue-cured tobacco support 6 of different lengths, eliminating the need to configure a separate transfer frame for each specification, thus reducing equipment procurement and management costs. It can improve adaptability and efficiency, cover flue-cured tobacco support 6 of different lengths, eliminate the need to replace equipment, quickly adjust the spacing to shorten preparation time, reduce the risk of tobacco leaf damage, accurately position to avoid support shaking and squeezing, and evenly distribute force to prevent deformation of the flue-cured tobacco support 6.

[0032] Specifically, the tobacco curing support 6 includes a placement frame 61 and a number of placement rods 62 arranged at equal intervals within the placement frame 61; tobacco leaves can be placed within the placement rods 62, thereby enabling the tobacco curing support 6 to place tobacco leaves in layers and to provide support and load-bearing capacity during subsequent curing.

[0033] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
