Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco disease prevention and control, and specifically relates to a tobacco diseased plant pesticide application device. Background Art

[0002] Common tobacco diseases include black root rot, black shank, etc., and most of them are fungal diseases. They often occur after the tobacco seedlings are transplanted into the field. In particular, high temperature and high humidity environments are more likely to cause the onset and spread of tobacco pathogens. Generally, tobacco plants infected with black rot are basically incurable and can easily trigger large-scale infections.

[0003] Tobacco root black rot mainly occurs on the root system of tobacco plants. The pathogen invades from the rhizome, and the lesions surround the stem, invade upward to the leaves and downward to the lateral roots, causing the entire seedling to die and the roots to turn specifically black and rot.

[0004] The existing pesticide application device uses a sprayer to apply the pesticide in a circular shape to the bottom stem of the tobacco plant, and then the pesticide flows along the stem to the root. However, in order to ensure that the pesticide liquid covers the stem and root system of the tobacco plant, the pesticide must be applied all around the stem of the tobacco plant, and the pesticide applicators need to apply the pesticide from multiple angles. The operation is cumbersome, inconvenient, time-consuming and labor-intensive. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a tobacco diseased plant pesticide application device to solve the problem that the existing pesticide application device is inconvenient to apply pesticides to the tobacco plant stems.

[0006] The utility model solves the above technical problems through the following technical means:

[0007] A tobacco diseased plant pesticide application device comprises a hollow sleeve with upper and lower openings, the bottom end of the sleeve is fixedly connected to two connecting plates, the end of the connecting plate is fixedly connected to the bottom plate, and two connecting frames are rotatably connected between the two connecting plates; the connecting frame comprises a straight arm and an arc-shaped arm, one end of the straight arm is rotatably connected to the connecting plate, and the other end of the straight arm is connected to the arc-shaped arm; a spring is provided on the side wall of the straight arm away from the bottom plate, and the other end of the spring is fixedly connected to the side wall of the sleeve; a pull rope is provided in the spring, one end of the pull rope is fixedly connected to the straight arm, and the other end of the pull rope extends to the inside of the sleeve, a pull rod is slidably connected in the sleeve, the top end of the pull rod extends to the outside of the top opening of the sleeve, and the bottom end of the pull rod is connected to the pull rope; a drug delivery tube is connected to the bottom of the sleeve, a switch valve is provided on the sleeve, and brackets are evenly distributed on the inner side wall of the arc-shaped arm, an annular hole is provided on the bracket, a nozzle is provided in the annular hole, the nozzle is connected to the drug delivery tube, and nozzles are evenly distributed on the nozzle.

[0008] On the basis of the above technical solution, the present invention also makes the following improvements:

[0009] Furthermore, a linkage valve is also provided on the drug delivery tube, and the linkage valve includes a valve body, a cylindrical cavity is provided in the valve body, connecting cavities communicating with the cylindrical cavity are provided at both ends of the valve body, a valve core is rotatably connected in the cylindrical cavity, a gear for driving the valve core to rotate is provided on the outside of the valve body, the gear is located inside the sleeve, a rack matching the gear is provided on the pull rod, and the valve core is in an open state in a natural state. By pulling the pull rod, the connecting frame can be opened at the same time, and the switch valve can be closed. When the connecting frame is opened for changing plants and applying medicine, the switch valve is in a closed state, which can save more liquid medicine, avoid waste, and make the operation simpler and more convenient.

[0010] Furthermore, a handle is provided on the top of the pull rod, and an anti-slip cover is provided on the handle.

[0011] Furthermore, the draw cord is made of anti-corrosion material.

[0012] Furthermore, the inner cavity of the sleeve is a rectangular cavity, and the outer shape of the pull rod matches the cavity of the sleeve.

[0013] The beneficial effects of the utility model are as follows: when the pull rod is pulled, the pull rod pulls the pull rope, the pull rope pulls the connecting frame to rotate, the connecting frame squeezes the spring, and the two connecting frames can be opened. The opened connecting frames are placed on both sides of the stems of the diseased tobacco plants, and then the pull rod is released. Under the elastic force of the spring, the spring can squeeze the connecting frames back onto the bottom plate, so that the two connecting frames are closed. The closed connecting frames can cover the stems of the diseased tobacco plants, and then the switch valve is opened, and the medicine liquid can flow into the nozzle and be sprayed around the stems through the nozzle, so that multi-angle spraying can be achieved at one time, avoiding multiple operations and being more convenient to use.
