Description

Technical Field

[0001] The invention relates to the technical field of integration of tobacco agriculture, agricultural machinery and agronomy, and in particular to a handheld adjustable cigar tobacco leaf topping and bud suppression integrated device and a use method thereof. Background Art

[0002] Cigars are a type of air-cured tobacco, and their production and sales have been in a state of sustained growth. At present, they have developed into a key development area in the tobacco industry. Cigars are very dependent on high-quality raw materials - cigar tobacco leaves. Due to the high economic value of cigar tobacco leaves and the high agronomic requirements for planting, cigar tobacco leaf production at home and abroad is mostly completed by manual labor. my country's cigar tobacco leaf planting history is short, the scale is small and scattered, the degree of mechanization is low, and there are few special plant protection machinery related to field management and the functions are single, resulting in high labor intensity for tobacco farmers and the failure to provide effective supply guarantees for high-quality raw materials. Therefore, mechanical research and development and production promotion are effective measures to reduce labor intensity, improve the quality of cigar tobacco leaf field management, and promote the construction of domestic high-quality cigar raw material supply guarantees.

[0003] Topping and bud suppression is an important technical measure in the field management of cigar tobacco leaves. Specifically, it refers to removing the top buds of the tobacco plants at an appropriate time and using bud inhibitors to block the growth of the top buds and axillary buds, so as to achieve directional regulation of the plant shape, leaf growth and ultimate yield and quality formation of the tobacco plants. Therefore, topping and bud suppression operations play an important role in the growth and quality shaping of cigar tobacco leaves.

[0004] Since the top buds of cigar tobacco leaves have multiple degrees of freedom, mechanized topping and bud suppression need to limit their multiple degrees of freedom, which is difficult. Therefore, the topping and bud suppression of cigar tobacco leaves in China and abroad are currently completed by manual operation. The operation process adopts a two-person mode of one person topping and one person suppressing buds. However, due to the high height of cigar tobacco plants, the manual operation speed is slow, the efficiency is low, the labor cost is high, and there are problems such as excessive and uneven spraying of bud suppressants, resulting in unsatisfactory bud suppression effects and high per-acre pesticide costs. Therefore, it is urgent to develop a machine that can realize the combined operation of topping and bud suppression of cigar tobacco plants in production to improve work efficiency, reduce labor intensity, reduce labor costs, and improve the comprehensive economic benefits of cigar tobacco planting.

During the closing process, the top bud clamping assembly 4 first contacts the top bud of the cigar tobacco leaf and gradually clamps it under the action of the pressure spring, and the top bud shearing assembly 5 contacts the top bud of the cigar tobacco leaf and starts cutting. After the fixed nozzle plate assembly 601 and the movable nozzle plate assembly 602 are completely closed, the top buds are completely cut off.

[0072] In the third step, the operator presses the pressure switch 1102 on the valve body 1105, and the bud inhibitor is filled into the internal pipe inside the semicircular arc protrusion 604 under the action of the valve body 1105, and a plurality of evenly arranged nozzles 605 are used to spray out an inverted cone-shaped bud inhibitor liquid column, which converges at the position of the top bud incision of the cigar tobacco leaf and flows along the cigar tobacco leaf stem to the side bud to complete the bud inhibition operation;

[0073] In the fourth step, the operator presses the control button 1104 again, and the servo 2 controls the movable nozzle plate assembly 602 to open. The operator collects the cut terminal buds and repeats the above operation to complete the bud suppression work of other cigar tobacco leaves.

[0074] The operation method is simple to operate and easy to execute, and can realize the combined operation of topping and bud suppression by a single person. It is adaptable to different cigar tobacco leaf topping heights, solves the problem of excessive application of bud suppressants in cigar tobacco leaf bud suppression operations, meets the agronomic requirements of cigar tobacco leaf topping and bud suppression, reduces labor, improves efficiency, and realizes efficient and high-quality cigar tobacco leaf topping and bud suppression operations.

[0075] 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.
