Intelligentized intra-row and intra-plant weeding device for crops in seedling stage

Abstract

The invention discloses an intelligentized intra-row and intra-plant weeding device for crops in a seedling stage. The intelligentized intra-row and intra-plant weeding device for the crops in the seedling stage comprises a frame, travelling wheels are arranged under the frame, the frame is provided with a power driving mechanism, an intra-row weeding mechanism, an intra-plant weeding mechanism and an intelligent electronic control system, wherein the power driving mechanism is connected with the intra-row weeding mechanism and the intra-plant weeding mechanism in a transmission mode respectively, and the intelligent electronic control system is connected with the intra-plant weeding mechanism through wires. According to the intelligentized intra-row and intra-plant weeding device for the crops in the seedling stage, the intra-row weeding mechanism and the intra-plant weeding mechanism are both compact in structure, flexible in movement and convenient to dismantle and install, the intra-plant weeding mechanism achieves axial free extension of intra-plant weeders by utilizing electromagnetic induction effects, so that the mechanical structure is greatly simplified, and the intelligent control of intra-plant weeding is achieved in combination with an image sensor, a distance measuring sensor and an AT89C52 chip.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly agricultural machinery, and in particular relates to an intelligent inter-row weeding device for crops at the seedling stage. Background technique [0002] Due to the close distance between the seedlings and the crops, weeds directly compete with the crops for water, nutrients and sunlight, seriously affecting the growth of the crops. At present, the methods of weeding the farmland after sowing and before harvesting of crops mainly rely on manual weeding or chemical weeding. Manual weeding is labor-intensive, time-consuming and labor-intensive, and the work efficiency is low; although chemical agents are effective in controlling weeds, chemical weeding is often Because the residual toxicity of chemical herbicides brings problems to crops and soil, such as biological extinction, weed community changes, weed resistance enhancement and resistance spectrum expansion, env...

AI Technical Summary

Problems solved by technology

Most of the mechanical weeders sold on the market are used for weeding in a wide area, such as lawns, forest farms, pastures, etc., and the bottom of the existing weeding device is close to the ground, so it can only walk between rows without crops. , and then use the weeding mechanism at the bottom to remove or pull out the weeds between the rows, so we can only remove the weeds between the rows and cannot remove the weeds between the seedlings in the row

In addition, there is a rotary tiller with weeding function. Pre-weeding is carried out before planting. The loosening shovel is mainly used for shallow loosening. Weeding is only an auxiliary function, and the operation effect is not ideal.
