Weeding robot with both functions of targeted quantitative spraying and mechanical fixed point shoveling

Abstract

The invention relates to a weeding robot with both functions of targeted quantitative spraying and mechanical fixed point shoveling. The weeding robot consists of a double-hub electric driving mechanical platform, a robot vision system, an intelligent control system, an automatic steering system, a horizontal maintaining mechanism, a foldable weeding platform, an alternative targeted quantitative spraying system, an electric assisting system and a feedback system. After the weeding robot is powered on, the robot vision technique is adopted to track orientation of in-field seedling zones, and automatic intelligent navigation can be achieved. Meanwhile the foldable weeding platform is unfolded, in-field data are acquired through five sets of image acquisition devices in real time, weed information is analyzed and integrated a pulse instructions, an electromagnetic valve is controlled to be opened and closed to drive a stepper motor on the foldable weeding platform to drive double nozzles to rotate so as to achieve space fixed point quantitative targeting spraying. The extension length of a push rod motor is adjusted through feedback of the sensor so as to adjust the horizontal holding mechanism, then a weeding mechanism is normally kept in equal distance from the ground horizon, and accurate weeding can be achieved through the weeding mechanism. The weeding robot can be applied to agricultural weeding operation.

Description

technical field [0001] The invention relates to the field of agricultural weeding machinery and equipment, and more specifically refers to an intelligent weeding robot using machine vision and spatial weeding equipment. Background technique [0002] Due to the continuous growth of the world's population, land desertification and irrational use, the area of ​​arable land is constantly decreasing. Therefore, only by increasing the yield per unit area of ​​land and reducing the losses caused by weeds can we rely on limited land to feed the growing population. Higher requirements are placed on human resources and agricultural weeding implements. However, according to the statistics of relevant experts at home and abroad, the losses caused by weeds to global food production are as high as 95 billion U.S. dollars every year, which shows the necessity of spraying pesticides. However, most common spraying methods are extensive spraying, regardless of the distribution characteristic...

However, according to the statistics of relevant experts at home and abroad, the annual loss of weeds to global food production is as high as 95 billion U.S. dollars, which shows the necessity of spraying pesticides

However, most common spraying methods are extensive spraying, regardless of the distribution characteristics of weeds and crops in the spatial area, spraying pesticides evenly on the entire field, blindly spraying pesticides in large quantities leads to problems such as soil compaction and food pesticide residues , which is not conducive to people's health; on the other hand, the existing agricultural weeding equipment is not suitable for many disadvantages due to its poor ability to independently regulate the weeding platform, low efficiency of spraying on targets, low precision of mechanical weeding actuators, and inconvenient transportation. In line with the concept of modern agriculture
