[0002] Tobacco leaf baking is a key step in the tobacco production process, which directly affects the quality, aroma, taste of tobacco leaves and the quality of the final tobacco products. The tobacco leaf baking process aims to control conditions such as temperature, humidity, and air flow to evaporate the moisture of tobacco leaves and carry out necessary chemical changes, so as to achieve the ideal state of tobacco leaves.

[0003] External substances on the tobacco leaf surface (foliar fertilizers, plant protection agents, etc.) refer to various substances directly applied through the leaves. By directly applying external substances on the tobacco leaf surface, it can provide necessary nutrients, resist pests and diseases, regulate growth, etc. for tobacco leaves. By selecting suitable foliar fertilizers, plant protection agents, growth regulators, sugars, organic substances, etc., the growth rate, yield and quality of tobacco leaves can be effectively improved, and the stress resistance can be improved.

[0004] In the prior art, before tobacco leaves are loaded into a bulk curing barn, for tobacco leaves carrying viruses or with low maturity, antiviral agents or hormonal substances need to be manually sprayed using a traditional medicine barrel before the tobacco leaves can be hung into the loading chamber for baking.

[0027] 1.

During the upward movement of the multiple other groups of mounting blocks, they respectively contact one end of the multiple groups of movable blocks. Since one end of the multiple groups of movable blocks is arc-shaped, the multiple groups of movable blocks displace, thereby driving the connecting column to displace, and further driving the first support block to displace, avoiding the multiple other groups of mounting blocks being blocked by the multiple groups of first support blocks during the continuous upward movement. After the multiple other groups of mounting blocks move to the upper region of the multiple groups of first support blocks, multiple groups of springs respectively push the multiple groups of movable blocks and the multiple groups of first support blocks to reset. The multiple groups of first support blocks respectively support the multiple other groups of mounting blocks.

A synchronous belt is connected between one of the first driving shafts 4 and one of the first limiting shafts 13. One of the first limiting shafts 13 rotates. The outer walls of the two first limiting shafts 13 are respectively threadedly connected to the inner walls of both ends of the scraper 12. The scraper 12 is displaced. The scraper 12 pushes the liquid medicine that has fallen to the bottom end of the main body 1 of the baking room, so that the liquid medicine falls into the diversion groove 10 and is discharged to the outside of the main body 1 of the baking room through the discharge pipe 10.

[0055] The working principle of the present invention is as follows: The staff place the tobacco leaves one by one in multiple sets of placing seats 14, and then cooperate multiple sets of clamping plates 15 with multiple sets of placing seats 14 to clamp and fix multiple sets of tobacco leaves. Then, the mounting blocks 16 at one end of multiple sets of placing seats 14 are respectively placed in the upper regions of multiple sets of first support blocks 23 and multiple sets of third support blocks 35, and the baking device 43 is turned on to perform the baking operation on the tobacco leaves;

[0056] When the tobacco leaves are baked for six hours, the external agent generator 8 injects the liquid or gaseous agent into the two sets of transmission pipes 9. Then, the transmission pipes 9 transmit the liquid or gaseous agent to the spraying plate 7, and the spraying plate 7 sprays the liquid or gaseous agent. At the same time, the first driving motor 3 starts to drive a set of first driving shafts 4 to rotate clockwise, and the two sets of first driving shafts 4 are connected by a synchronous belt. Therefore, the two sets of first driving shafts 4 rotate synchronously. The outer walls of the two sets of first driving shafts 4 are respectively threadedly connected to the inner walls of the two sets of movable seats 5, and the two sets of movable seats 5 are displaced, thereby driving the spraying plate 7 to be displaced;

[0057] When the two sets of movable seats 5 are displaced, they drive the two sets of first toothed plates 6 to be displaced. The two sets of first toothed plates 6 are respectively meshed and connected with the two sets of transmission gears 39, and the two sets of transmission gears 39 rotate to drive the two sets of first transmission shafts 17 to rotate. The two sets of first transmission rotating shafts 17 are respectively connected by a synchronous belt to the two sets of first linkage shafts 18, and the two sets of first linkage shafts 18 rotate, thereby driving the two sets of linkage bevel gears 19 to rotate. The two sets of linkage bevel gears 19 are respectively meshed and connected with the two sets of movable bevel gears 21, and the two sets of movable bevel gears 21 rotate, thereby driving the two sets of first movable shafts 20 to rotate;

[0058] When the two sets of first movable shafts 20 rotate, and the two sets of first movable shafts 20 are respectively connected by a synchronous belt to multiple sets of second limiting shafts 27 and multiple sets of second transmission shafts 29, therefore, multiple sets of second limiting shafts 27 and multiple sets of second transmission shafts 29 rotate. The outer walls of multiple sets of second limiting shafts 27 are respectively threadedly connected to the inner walls of multiple sets of first pushing plates 28, and multiple sets of first pushing plates 28 push multiple sets of mounting blocks 16 to be displaced. At the same time, multiple sets of second transmission shafts 29 rotate, and multiple sets of second transmission shafts 29 are respectively connected by a synchronous belt to multiple sets of second linkage shafts 30, and multiple sets of second linkage shafts 30 rotate. The outer walls of multiple sets of second linkage shafts 30 are respectively threadedly connected to the inner walls of multiple sets of second support blocks 31, and multiple sets of second support blocks 31 are displaced. One ends of multiple sets of second support blocks 31 respectively move into the grooves on one side of multiple sets of limiting bins 22, and then multiple sets of first pushing plates 28 respectively push multiple sets of mounting blocks 16 to move to the upper ends of multiple sets of second support blocks 31, so that multiple sets of tobacco leaves are arranged in a staggered manner inside the baking room, improving the spraying effect of the external agent on the surface of the tobacco leaves;

[0059] Two groups of movable seats 5 continue to move, and the two groups of movable seats 5 drive the two groups of first toothed plates 6 to move to one side of the other two groups of transmission gears 39, driving the other two groups of transmission gears 39 to rotate. Due to the setting of the one-way bearings at the central ends of the other two groups of first linkage shafts 18, the bottom ends of the other two groups of first linkage shafts 18 do not rotate. After the two groups of movable seats 5 move to one end of the two groups of first drive shafts 4, the first drive motor 3 is turned off, and the two groups of second drive motors 32 are started, driving the two groups of second drive shafts 33 to rotate clockwise. The two groups of second drive shafts 33 are respectively connected to the two groups of contraction cylinders 34 through synchronous belts, and the two groups of contraction cylinders 34 rotate. The multiple contraction cylinders 34 are respectively connected through synchronous belts, and the multiple contraction cylinders 34 rotate. The inner walls of the multiple contraction cylinders 34 are threadedly connected to the outer walls of the multiple telescopic columns, so the multiple telescopic columns move upward, thereby pushing the multiple third support blocks 35 upward;

[0060] After the multiple third support blocks 35 move upward, the multiple third support blocks 35 respectively move into the multiple limit bins 22, and then push the other multiple mounting blocks 16 upward. During the upward movement of the other multiple mounting blocks 16, they respectively touch one end of the multiple movable blocks 25. Since one end of the multiple movable blocks 25 is arc-shaped, the multiple movable blocks 25 move, thereby driving the connecting columns 24 to move, and further driving the first support blocks 23 to move, avoiding the obstruction of the other multiple mounting blocks 16 by the multiple first support blocks 23 during the continuous upward movement. After the other multiple mounting blocks 16 move to the upper region of the multiple first support blocks 23, the multiple springs 26 respectively push the multiple movable blocks 25 and the multiple first support blocks 23 to reset, and the multiple first support blocks 23 respectively support the other multiple mounting blocks 16;

[0061] During the upward movement of the other multiple mounting blocks 16, the first drive motor 3 drives the two groups of first drive shafts 4 to rotate counterclockwise. The two groups of first toothed plates 6 are respectively meshed with the other two groups of transmission gears 39, driving the other two groups of transmission gears 39 to rotate, thereby driving the other two groups of first transmission shafts 17 to rotate, enabling the multiple first push plates 28 and the multiple second support blocks 31 to reset. The multiple second support blocks 31 release the support for the multiple mounting blocks 16, and the multiple mounting blocks 16 fall to the bottom ends of the multiple limit bins 22. The rubber cushions on the outer walls of the multiple mounting blocks 16 respectively touch the inner walls of the multiple limit bins 22, slowing down the falling speed of the mounting blocks 16 and protecting the multiple mounting blocks 16, causing the tobacco leaves originally in the upper space to move to the lower space, and the tobacco leaves originally in the lower space to move to the upper space, changing the regions where the multiple tobacco leaves are located, and changing the positions where the multiple tobacco leaves are sprayed by external aids, further improving the spraying effect of external aids on the surface of the tobacco leaves;

[0062] After multiple groups of first support blocks 23 respectively support multiple other groups of mounting blocks 16, two groups of second drive motors 32 drive two groups of second drive shafts 33 to rotate counterclockwise, thereby driving multiple groups of contraction cylinders 34 to rotate counterclockwise, thereby driving multiple groups of telescopic columns to displace downward, and further driving multiple groups of third support blocks 35 to displace downward. Multiple groups of third support blocks 35 move out of multiple groups of limit bins 22. Among them, two groups of third support blocks 35 drive two groups of second toothed plates 36 to move into the wall of the baking room main body 1, so that the two groups of second toothed plates 36 are respectively meshed and connected with two groups of movable gears 38, and the two groups of movable gears 38 rotate, thereby driving two groups of second movable shafts 37 to rotate;

[0063] When the two groups of second movable shafts 37 rotate, the two groups of second movable shafts 37 are respectively connected to two groups of third limit shafts 40 through synchronous belts, and the two groups of third limit shafts 40 rotate. Moreover, the outer walls of multiple groups of third limit shafts 40 are respectively connected to two groups of third movable shafts 42 through synchronous belts. Therefore, the two groups of third limit shafts 40 respectively drive the two groups of third movable shafts 42 to rotate, thereby driving multiple groups of third limit shafts 40 to rotate synchronously. The threaded grooves on the outer walls of multiple groups of third limit shafts 40 are respectively movably connected to the convex blocks on the inner walls of multiple groups of second push plates 41. Multiple groups of second push plates 41 displace, thereby pushing multiple groups of mounting blocks 16 to displace, so that multiple groups of mounting blocks 16 move to the upper region of multiple groups of third support blocks 35, and then multiple groups of second push plates 41 reset;

[0064] When the two groups of first drive shafts 4 rotate, one group of first drive shafts 4 is connected to one group of first limit shafts 13 through a synchronous belt, and one group of first limit shafts 13 rotates. Moreover, the outer walls of the two groups of first limit shafts 13 are respectively threadedly connected to the inner walls at both ends of the scraper 12. The scraper 12 displaces, and the scraper 12 pushes the liquid medicine that has fallen to the bottom end of the baking room main body 1, so that the liquid medicine falls into the diversion groove 10 and is discharged to the outside of the baking room main body 1 through the discharge pipe 10, avoiding the influence of the liquid medicine remaining at the bottom end of the baking room main body 1 on the baking effect of the tobacco leaves inside the baking room main body 1.
