Technical Field

[0002] The inadequate opening and tight structure of the upper tobacco leaves of flue-cured tobacco have always been a problem in my country's tobacco production. Many scholars and technicians have explored a variety of technical means, including cultivation measures such as adjusting the planting density of tobacco plants, coordinating nutrient management, and coordinating the efficient use of water and fertilizer. They have also tried to promote the development and opening of the upper tobacco leaves by spraying plant growth regulators, so as to improve the tissue structure and looseness of the leaves and improve the quality and availability of tobacco leaves. However, there is currently a lack of suitable technical measures or methods to promote the opening of the upper tobacco leaves, which limits the quality improvement and industrial use value of the upper tobacco leaves. There are some methods that promote the opening of the upper leaves by using chemical regulators, but they have not been widely used. On the one hand, it may be that the opening effect is not ideal, the effect of improving the quality of the upper tobacco leaves is limited, the economic benefits are not high, and even the cost is too high, which is not accepted by tobacco farmers; on the other hand, it may be that the addition of exogenous substances changes the aroma and flavor of tobacco leaves, affecting the use of tobacco leaves in the formula and not being recognized by industrial applications.

[0060] Working principle: when the tobacco leaves need to be sprayed with the tablet solution, the spraying device is placed across the tobacco, and the concave support seat 1 is placed across the tobacco; the spraying device is moved to the top of the tobacco to be sprayed by pushing the handrail 15, and the position of the tobacco leaves is identified by the scanning device identification device 25;

[0061] First, the motor shaft of the servo motor drives the driving gear 65 to rotate, the driving gear 65 drives the limiting circular tube 63 to rotate, the limiting circular tube 63 drives the adjusting circular plate 6 to rotate, and the adjusting circular plate 6 drives the circular rod 54 to move when rotating, so that the circular rod 54 slides inward along the inclined groove 61 of the adjusting circular plate 6, and the circular rod 54 drives the T-shaped slider 53 to slide inward along the T-shaped groove 41, so that the inner rod 52 drives the lower end of the outer support sleeve 5 to open outward, and then the bending plate 51 opens outward;

[0062] At this time, the inner rod of the electric telescopic rod 2 extends downward to drive the lifting and moving plate 21 to move downward, and the lifting and moving plate 21 drives the rotating mechanism, the clamping mechanism, the driving mechanism and the spraying mechanism to move downward, so that the multiple curved plates 51 are distributed below the outer side of the tobacco leaves and are above the tobacco leaves that do not need to be sprayed;

[0063] Then, the motor shaft of the servo motor is reversed to reverse the driving gear 65, so that the limiting circular tube 63 drives the adjusting circular plate 6 to reverse, and the circular rod 54 is pushed outward by the adjusting circular plate 6, and the circular rod 54 drives the T-shaped slider 53 to slide outward along the T-shaped slot 41, so that the inner rod 52 drives the lower end of the outer supporting sleeve 5 to shrink inward, and then the bending plate 51 shrinks inward, so that the bending plate 51 is closely attached to the lower side of the tobacco leaf, and at the same time, the bending plate 51 pushes the tobacco leaf to flip upward, so that the tobacco leaf approaches the vertical shape near the curved plate 51, especially the tobacco leaf below the inner side of the curved plate 51 is the closest to the vertical shape;

[0064] At this time, the tablet opening solution in the liquid storage tank 17 is pumped out through the pump body 18 and transported to the liquid outlet pipe 7 through the spiral hose 72. A part of the tablet opening solution is sprayed out along the three-head nozzle 73, and the other part of the tablet opening solution is sprayed out along the second nozzle 75 at the lower end of the L-shaped bending tube 74, so that the tablet opening solution can be sprayed on the front and back sides of the tobacco leaves under the curved plate 51 at the same time.

[0065] At the same time, the inner rod of the electric telescopic rod 2 contracts upward, driving the lifting and moving plate 21 to move upward, so that the rotating mechanism, the clamping mechanism, the driving mechanism and the spraying mechanism move upward. During the upward movement of the curved plate 51, it slides upward along the side of the tobacco leaves, and at the same time pushes the tobacco leaves to reverse and approach a vertical state. At this time, the three-head nozzle 73 and the multiple second nozzles 75 move upward at the same time, so that the tablet solution can be evenly sprayed on the front and back sides of the tobacco leaves, and multiple tobacco leaves can be sprayed at one time, which greatly improves the work efficiency. At the same time, it can spray evenly, improving the effect of spraying the tablet solution on the tobacco leaves.

[0066] When the curved plate 51 is separated from the tobacco leaves, the tobacco leaves flip downward to return to their original state, and the spraying operation on one side is completed. At the same time, the lifting and moving plate 21, the rotating mechanism, the clamping mechanism, the driving mechanism and the spraying mechanism move upward to the top, that is, return to their original position.

[0067] When it is necessary to spray other tobacco leaves of the tobacco, the main gear 32 is driven to rotate by the output shaft of the stepper motor, the main gear 32 drives the annular outer gear 31 to rotate, the annular outer gear 31 drives the circular sleeve 3 to rotate along the circular groove 23, and at the same time the circular sleeve 3 drives the circular chassis 4 to rotate synchronously through the positioning frame 33 and the limiting side plate 34. The positioning frame 33 and the circular chassis 4 are coordinated to make the gripping mechanism, the driving mechanism and the spraying mechanism rotate synchronously, so that the curved plate 51 and the spraying mechanism rotate to the top of the tobacco leaves to be sprayed, and then the above operation is performed to make the gripping mechanism open outward, and then the curved plate 51 in the gripping mechanism moves downward to the bottom of the outer side of the tobacco leaves to be sprayed, so as to perform the spraying operation again.

[0068] When the spraying of one tobacco plant is completed, the spraying device is moved to the top of another tobacco plant, and the above operation is repeated. The spraying device of the present application only needs to spray on both sides of the tobacco leaves of one tobacco plant, which greatly improves the spraying efficiency, achieves a good uniform spraying effect, and greatly reduces the labor intensity of the staff.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
