Description

Technical Field

[0002] The strip-type composite planting technology of soybean and corn mainly utilizes the differences in the genetic and biological characteristics of soybean and corn in shade tolerance and density tolerance to realize the intercropping of multiple rows of corn and multiple rows of soybean, thereby improving the utilization rate of light energy, nutrients and water. However, corn belongs to the grass family and soybean belongs to the broad-leaved plant. The stem and leaf herbicides used by both are lethal to each other. Therefore, how to achieve weed control in composite planting is an issue that must be considered in the existing technology.

[0003] The patent number CN218073219U in the prior art discloses a spraying device for corn and soybean strip intercropping fields, including a vehicle body, a liquid storage tank for storing liquid medicine, a spray pipe for spraying medicine to the field, a connecting pipe for connecting the liquid storage tank and the spray pipe, and a liquid pump used in conjunction with the connecting pipe; the spray pipe is arranged at the rear end of the vehicle body, slidably connected to the vehicle body, and the height of the spray pipe is adjustable; baffles are also arranged at both ends of the spray pipe to prevent pesticides from spraying outward. The device can adjust the height of the spray pipe and the nozzle according to the height of the crop, so that it can adapt to crops of different heights; the device can form a physical isolation between different crops in the strip intercropping field, so that one herbicide can only act on one crop and has no effect on other crops.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) The prior art device does not have the function of mixing and stirring the spray liquid, which can easily cause the nozzle to be blocked during use, resulting in reduced spraying efficiency.

[0006] (2) When the device of the prior art is used, only one crop can be sprayed with pesticides at a time during field operation. The efficiency of applying pesticides separately by a single sprayer is low, and the manpower and mechanical weeding input are doubled, which is time-consuming and labor-intensive, increases the labor intensity of the operator, and reduces the working efficiency of the device.

[0007] (3) The baffle of the prior art device cannot be adjusted in position according to the ratio of crop rows, and it is not convenient to adjust the spraying range according to the different spacing of intercropping during spraying, which is inconvenient to use. Utility Model Content
