Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology and discloses a weeding and spraying device for corn-soybean strip intercropping. Background Technology

[0002] Corn-soybean strip intercropping is a highly efficient intercropping model that makes full use of land and sunlight resources to increase crop yields. However, in this model, the corn and soybeans are distributed in strips with intervals, which places high demands on the precision and adaptability of weeding and spraying operations.

[0003] Existing spraying devices have many shortcomings. The width and row spacing of corn strips and soybean strips vary significantly in different regions and under different planting schemes. Furthermore, the layout parameters of the same plot may be adjusted at different planting cycles. Traditional spraying devices have a fixed spraying width, which cannot flexibly adapt to diverse strip layouts. This can easily lead to problems such as missed spraying in areas with dense weeds and over-spraying in crop planting areas, which not only affects the weeding effect but may also lead to pesticide waste or crop damage. The fixed nozzle angle cannot target and cover weed areas between crop rows. Utility Model Content

[0004] This invention addresses the problems of poor adaptability and inconvenient adjustment of existing spraying devices in corn-soybean strip intercropping by providing a weeding spraying device for corn-soybean strip intercropping.

[0005] To achieve the above-mentioned technical effects, the technical solution adopted by this utility model is: a corn-soybean strip intercropping weeding spraying device, comprising: a vehicle body, on which two placement slots are provided, each containing a mixing drum, the input end of which is connected to an injection pipe; two movable plates, on the outer wall of the vehicle body, with width adjustment components on the vehicle body for adjusting the movement of the two movable plates along the width direction of the vehicle body; and two mounting brackets, each on the two movable plates being slidably connected to a mounting bracket, and the movable plates being equipped with height adjustment components for adjusting the mounting... The bracket moves along the height of the movable plate; two rotating parts are rotatably connected to both of the mounting brackets, and the mounting brackets are equipped with locking components to lock the angle of the rotating parts; two pesticide nozzles are mounted on both of the rotating parts; two mounting plates are respectively mounted on the two movable plates, and the mounting plates are connected to adapter pipes. The input end of the adapter pipe is connected to the output end of the mixing drum through a first telescopic pipe. The output end of the mixing drum is equipped with a pump body, and the output end of the adapter pipe is connected to the input end of the pesticide nozzle through a second telescopic pipe.

[0011] As a preferred embodiment, both the first and second telescopic pipes are bellows-type telescopic pipes.

[0012] Compared to existing technologies, this novel width-adjusting component uses an electric telescopic rod to drive the movable plate, adapting to corn-soybean strip intercropping patterns of varying widths and preventing missed or excessive spraying. The height-adjusting component uses a screw drive to raise and lower the mounting bracket, flexibly adjusting the nozzle height according to crop growth, ensuring effective weed control while avoiding crop damage. The rotating component adjusts the nozzle angle, and the locking component locks the position, allowing for targeted coverage of weed areas between crop rows, improving spray accuracy.
