Description

Technical Field

[0001] This invention provides a precision application device for tobacco diseases, belonging to the field of tobacco disease control technology. Background Technology

[0002] Tobacco is one of my country's major economic crops and an important source of national fiscal revenue. In tobacco cultivation, tobacco diseases are one of the major natural disasters threatening tobacco production in the ecological environment, affecting tobacco yield and quality, and even causing significant economic losses. Therefore, during the tobacco cultivation period, in order to prevent the occurrence of tobacco diseases in the early stages, it is necessary to use pesticide application devices to apply pesticides to the root and stem parts of the tobacco plant.

[0003] Current pesticide application devices for tobacco diseases can generally meet normal usage needs, but they still have certain shortcomings: Since tobacco diseases are typically divided into stem and leaf diseases and root diseases, the nozzles of existing pesticide application devices often have a fixed orientation and a fairly wide spray range. This easily leads to low utilization of pesticide resources, with a significant portion of the sprayed pesticide going to waste, resulting in relatively imprecise application to tobacco plants. Therefore, this invention provides a precision pesticide application device for tobacco diseases. Utility Model Content

[0004] The technical problem solved by this utility model is that the spraying range is quite wide when applying pesticides, resulting in a considerable portion of the sprayed pesticide solution being wasted, low utilization rate of pesticide solution resources, and insufficient precision when applying pesticides to tobacco plants.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a precision spraying device for tobacco diseases, including a base, a medicine box on the top of the base, spraying components on both sides of the medicine box, a pump on the top of the medicine box for supplying liquid to the spraying components, the spraying components including a support block 1 and a driving part for driving the support block 1 to move, electric push rods symmetrically arranged on both sides of the support block 1, a support block 2 at the telescopic rod end of the electric push rod 2, a spray pipe at the bottom of the support block 2, a C-shaped frame at the bottom of the spray pipe, a laser rangefinder for measuring the distance of the spray pipe at the bottom inside the C-shaped frame, a nozzle 2 at the bottom outside the C-shaped frame, and a three-way valve connecting the spray pipe and the nozzle 2.

[0006] Furthermore, the drive unit includes a slide groove fixedly installed on the side wall of the medicine box, a slider slidably connected in the slide groove, an electric push rod on the side wall of the slider, the telescopic rod end of the electric push rod being fixedly connected to one side wall of the support block, a screw threadedly connected to the slider being rotatably connected between the upper and lower side walls of the slide groove, and the top end of the screw protruding from the top of the slide groove and having a handle.

[0007] Furthermore, the two inner sidewalls of the slide are symmetrically provided with limiting rails that match the sidewalls of the slider.

[0008] Furthermore, the nozzle has several nozzles equidistantly arranged on its body, and the top of each nozzle is provided with a connecting pipe that is fixedly connected to the bottom of the C-shaped frame. A diversion pipe is provided between the connecting pipe and one side of the three-way valve, and between the nozzle and the other side of the three-way valve.

[0009] Furthermore, the pump has a pumping port with a pumping tube that is inserted into the lower part of the medicine box, and a delivery port with a three-way connector. The two sides of the three-way connector are equipped with delivery tubes, and a delivery hose is connected between the delivery tubes and the three-way valve.

[0010] Furthermore, the top of the medicine box is provided with support plates placed on both sides of the liquid pump to support the infusion tube.

[0011] Furthermore, the base is symmetrically equipped with casters at the four corners of the bottom, the medicine box is symmetrically equipped with handles on one side wall, the medicine box is equipped with a battery box on the side wall, and the battery box is equipped with a controller on the top.

[0012] The beneficial effects of this utility model are:

[0013] The drive unit raises and lowers the nozzle and nozzle 2 to the appropriate position. Activating the electric push rod 1 moves the nozzle and nozzle 2 to the middle of adjacent tobacco plants. Activating the electric push rod 2 moves the nozzle and nozzle 2 left and right. A laser rangefinder measures the distance between the nozzle and the tobacco plant, allowing the nozzle and nozzle 2 to move to the appropriate position next to the adjacent tobacco plant, achieving precise application of pesticides. Operating the three-way valve starts the pump, allowing the pesticide solution in the tank to be sprayed from nozzle 2 onto the soil around the tobacco roots, and from several nozzles 1 onto the stems and leaves of the tobacco plants, according to the needs of treating root and leaf diseases. This allows for precise application of pesticides to the stems, leaves, and roots based on the tobacco disease situation, improving the utilization rate of pesticide resources and effectively preventing a significant portion of the sprayed solution from being wasted, making the application more flexible.
