Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production, in particular to a spraying device for preventing and controlling corn diseases and insect pests. Background Art

[0002] Corn is the most widely distributed crop in the world, and people in parts of my country rely on it as their staple food. During the initial planting phase, corn requires the use of various pesticides to prevent diseases such as brown leaf spot. Furthermore, after the corn has grown, farmers must constantly monitor the condition of their fields and spray pesticides promptly to control pests. This requires the use of a corn pest control sprayer. However, traditional corn pest control sprayers have some shortcomings.

[0003] While conventional sprayers have some design options for nozzle height adjustment, their functionality is relatively limited. Most can only adjust the nozzle height within a limited range, and cannot adjust the nozzle angle. In actual cornfield spraying operations, the height and density of corn plants vary significantly across different growth stages and plots. Simply adjusting the nozzle height cannot ensure uniform spraying of the pesticide to all parts of the corn plant, especially the front and back of leaves, stems, and lower parts of the plant, which are vulnerable to pests and diseases. This results in insufficient spraying of the pesticide in some areas, significantly reducing pest control effectiveness, while excessive spraying may occur in other areas, resulting in not only pesticide waste but also potentially adversely affecting the soil and environment. Furthermore, the design of the spray tank in existing sprayers also has flaws. The pesticide often settles in the tank, especially for mixed pesticides containing multiple ingredients. Due to the lack of an effective stirring mechanism, the concentration difference between the pesticide at the bottom of the tank and the concentration in the upper part gradually increases as the spraying operation progresses. This results in unstable spray concentration and affects the consistency of pest control effectiveness. Utility Model Content

[0004] The utility model discloses a spraying device for preventing and controlling corn diseases and insect pests, aiming to solve the technical problems of single adjustment mode and sedimentation of medicine tanks proposed in the background art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A spraying device for controlling corn diseases and insect pests comprises a frame, two adjusting vertical bins are fixedly connected to the right side of the top of the frame, an adjusting mechanism is fixedly connected to the top of the adjusting vertical bin, and the adjusting mechanism passes through the top of the adjusting vertical bin and is rotatably connected to the inner wall of the bottom of the adjusting vertical bin, a medicine tank is fixedly connected to the top of the medicine tank, a tank cover is fixedly connected to the top of the tank cover, a stirring mechanism is fixedly connected to the top of the medicine tank, a medicine tank mounting plate is fixedly connected to the bottom of the medicine tank, and a plurality of mounting fasteners are provided on the medicine tank mounting plate.

[0007] In a preferred solution, a vertical bin cavity is opened inside the adjustment vertical bin, and the vertical bin cavity includes a height adjustment cavity and a swing head groove. A swing head guide groove is opened on the inner surface of the height adjustment cavity, and an adjustment guide groove is opened on the back of the adjustment vertical bin.

[0008] In a preferred solution, the adjustment mechanism includes an adjusting motor, an adjusting screw is fixedly connected to the driving end of the adjusting motor, an adjusting sleeve is threadedly connected to the surface of the adjusting screw, an adjustment guide block is fixedly connected to both the top and bottom sides of the adjusting sleeve, a swing head block is rotatably connected to the outer surface of the adjusting sleeve, an agent connecting pipe is fixedly connected to the back of the swing head block, a nozzle is fixedly connected to the front of the swing head block, and swing head guide rods are fixedly connected to the left and right sides of the swing head block.

[0009] In a preferred solution, the adjustment motor is fixedly connected to the top of the adjustment vertical bin, the adjustment guide block is slidably connected to the inner surface of the adjustment guide groove, and the swing head guide rod is adapted to the swing head guide groove.

[0010] In a preferred solution, a liquid medicine inlet is provided on the top of the tank cover, and a water inlet is provided on the top of the tank cover.

[0011] In a preferred embodiment, the stirring mechanism includes a stirring mounting plate, to which a stirring motor is fixedly connected, a driving column is fixedly connected to the driving end of the stirring motor, and stirring rods are fixedly connected to the left and right sides of the driving column.

[0012] In a preferred solution, a medicine pump is fixedly connected to the top of the frame, a pushing frame is fixedly connected to the left side of the frame, two push handles are fixedly connected to the pushing frame, and four universal wheels are fixedly connected to the bottom of the frame.

[0013] From the above, it can be seen that the spraying device for controlling corn diseases and insect pests provided by the utility model has the following technical effects.

[0014] First: by setting up an adjustment mechanism that cooperates with the adjustment vertical bin, the adjustment motor is used to drive the adjustment screw to rotate, and the adjustment sleeve can be made to perform vertical linear motion on the adjustment screw through the threaded connection and the adjustment guide block, thereby making the swing head block move up and down. In the process of the swing head block moving up and down, due to the matching swing head guide rod and swing head guide groove, the swing head block swings left and right during the up and down movement, causing the spraying angle of the sprinkler head in the swing head groove to change. The sprinkler head is connected to the agent connecting pipe. The design of the changeable sprinkler head angle enables the device to adapt to the shape and growth condition of the corn plant more flexibly when spraying corn. No matter whether the plants are short and have fewer leaves in the early stage of corn growth, or when the plants are tall and have dense leaves in the middle and late stages of growth, the sprinkler head angle can be adjusted to ensure that the agent is evenly sprayed on all parts of the corn plant.

[0015] Secondly, a stirring mechanism is installed. After the pesticide and mixing water are introduced into the medicine tank through the liquid inlet and the water inlet, the stirring motor is activated, and the drive column on the stirring motor begins to rotate, which in turn causes the stirring rod to move in a circular motion around the drive column inside the medicine tank, stirring the pesticide inside the tank and effectively preventing the pesticide from settling in the tank. During the spraying process, regardless of the duration of the spraying operation, the concentration of the pesticide sprayed from the tank remains stable, avoiding fluctuations in the control effect caused by changes in pesticide concentration, and improving the reliability and accuracy of pest control.
