The utility model discloses a tobacco leaf grading and sorting device based on intelligent identification, which relates to the technical field of tobacco leaf conveying and storage and comprises a conveying unit, a grading unit, a sorting unit and a control unit. The conveying unit comprises a first conveying belt, the sorting unit is arranged at the tail end of the first conveying belt, the grading unit is arranged above the first conveying belt, the control unit is arranged on the outer side of the conveying unit, and the control unit is in control connection with the conveying unit, the grading unit and the sorting unit. The first conveying belt is used for conveying tobacco leaves, the grading unit is used for scanning and grading the tobacco leaves, and the control unit is used for controlling the sorting unit to sort the tobacco leaves according to grading information of the grading unit on the tobacco leaves. By means of the arrangement, the whole process of tobacco leaf grading can be achieved without manual participation in the whole process, the slicing, grading and grading efficiency is effectively improved, cost is reduced, and the tobacco leaf grading device has wide application prospects.

The utility model relates to tobacco prevention and cure with precision dispenser of pesticide class belongs to tobacco prevention and cure technical field, this tobacco prevention and cure with precision dispenser of pesticide class, including placing plate and the battery of installation in the top of placing plate, the top fixedly connected with mixing bucket of placing plate has installed filter mechanism in mixing bucket, the bottom fixed communication of mixing bucket has water pump, the liquid discharge end of water pump is fixedly communicated with the pesticide spraying frame through the liquid injection pipe, the bottom of pesticide spraying frame is provided with pesticide spraying hole, the adjusting mechanism for adjusting the height of pesticide spraying frame is fixedly connected on the placing plate. The utility model discloses the cooperation of elevating motor, elevating screw rod, fixed bin and slide board is used, when carrying out the plant disease and insect pest control to tobacco, can adjust the height of pesticide spraying frame distance tobacco according to the growth of tobacco, and further reduces the pesticide waste problem caused by the large pesticide drift amount of the high pesticide spraying frame and pesticide height, thereby realizes the precision pesticide application to tobacco, guarantees the quality of tobacco plant disease and insect pest control.

The invention relates to a smoke-control coarse moxa stick integrally rolled by multiple layers of kraft paper, and belongs to the technical field of traditional Chinese medicine instruments. According to the moxa stick, 3-6 layers of kraft paper are adopted to directly wrap moxa to form an integrated structure, a traditional double-layer process of thin paper roll core and thick paper tube is replaced, the length of a final product is 150-250 cm, and the diameter of the final product is 5-10 cm. By controlling the layer number of the kraft paper, the rolling compactness and the breathable micro-pore design, the breathability is ensured while the structural strength is maintained, and the moxa is fully combusted. The combustion time can reach 15-18 hours, the center temperature is stabilized in a low-temperature interval of 180-220 DEG C, and the residue rate and the smoke amount are remarkably reduced. The preparation method comprises the steps of kraft paper cutting (the width is 2.05-2.5 times of the length of a moxa stick), adhesive coating (the adhesive width is 1-3 cm), multi-roller synchronous rolling and pressing and cutting forming, the production process is simplified, and addition of a smoke control additive is avoided. According to the scheme, the problems that a traditional technology is tedious in procedure, insufficient in combustion and large in smoke are solved, and the method is suitable for large-scale production of thick moxa sticks with the diameter being 5-10 cm.

This invention discloses a control method, control device, central smoke control system, and computer-readable storage medium for a central smoke control system. The control method includes: acquiring the actual required air volume and total pressure rise for each floor; matching the operating conditions of auxiliary fans and terminal smoke control fans based on the actual required air volume and total pressure rise to obtain the target speeds of the auxiliary fans and terminal smoke control fans; the auxiliary fans are installed in the terminal smoke ducts, which connect to the common smoke duct and the terminal smoke control fans; controlling the auxiliary fans to operate at their target speeds, and controlling the fans of the terminal smoke control fans to operate at their target speeds. This control method, by adding auxiliary fans to the terminal smoke control fans, allows the auxiliary fans to provide total pressure rise, reducing the pressure rise at the fans of the terminal smoke control fans, which helps improve noise levels and also widens the coverage of the total pressure difference between two floors, significantly expanding the operating condition coverage of the central smoke control system.
