The utility model discloses intelligent weeding equipment based on visual navigation, and relates to the technical field of intelligent weeding equipment. In order to solve the problems that transverse movement in a field and increase and decrease of the operation number of weeding components of an existing weeding machine in the using process need manual adjustment, ridges are prone to being damaged in the working process, the using convenience of the weeding machine is reduced, mechanical weeding mostly refers to inter-row weeding, the inter-plant weed effect is not ideal, weeds cannot be intelligently recognized, and the weeding efficiency is high. And the operation path of the weeding machine is planned for efficient weeding. The device comprises a connecting frame, a translation mechanism, a turnover mechanism and a visual navigation mechanism, one side of the connecting frame is movably connected with a weeding mechanism, the other side of the connecting frame is connected with a supporting wheel, and the weeding mechanism comprises a rack, a weeding shovel and weeding fingers; the rack is movably connected to the connecting frame, a plurality of weeding shovels and a plurality of weeding fingers are arranged on the rear side of the rack, and a visual navigation mechanism is arranged at the upper end of the rack. The farmland weeding machine is used for farmland weeding.

This invention discloses a design method and device for a wheat field weeding actuator based on an operational power consumption model. The weeding actuator includes a rotary blade and a roller, with multiple rotary blades connected to the roller. The initial position is taken as the tip of the rotary blade contacting the soil. The entire weeding process is divided into four working conditions: contacting the soil, cutting the soil, chopping the grass, and lifting the soil. The rotary blade weeding actuator then employs a power consumption model during operation: W = ∑ i 1(W1+W2+W3+W4); The wheat field weeding device mainly consists of a rotary blade, rollers, a drive motor, a controller, and auxiliary mechanisms. The actuator of this invention uses a weeding wheel structure. By analyzing the robot-soil-weed interaction during wheat field weeding, a power consumption model of the rotary blade weeding robot actuator is constructed, and the structural parameters with the lowest power consumption during operation are determined. This not only results in a wide working area, low operating resistance, and high weeding efficiency, but also effectively solves the problem of high seedling damage rate when weeding crops with small row spacing.

The invention discloses a wheat field hoeing actuator design method and device based on an operation power consumption model, the hoeing actuator comprises hobs and rollers, a plurality of hobs are connected to the rollers, and the whole hoeing process is divided into four working conditions: soil touching, soil cutting, grass chopping and soil raising by taking the contact of the end points of the blades of the hobs of the actuator with soil as the initial position. A power consumption model is adopted when the hob type weeding actuator works, wherein W = sigma i1 (W1 + W2 + W3 + W4); the wheat field weeding device is mainly composed of a hob, a roller, a driving motor, a controller and an auxiliary mechanism. The actuator adopts a weeding wheel type structure, the robot-soil-weed interaction relation in the wheat field hoeing process is analyzed, a hob type hoeing robot actuator power consumption model is constructed, structural parameters with the lowest power consumption in operation are determined, the working breadth is wide, the operation resistance is small, the hoeing efficiency is high, and the hoeing efficiency is high. And the problem of high seedling damage rate during weeding of small-row-spacing crops is effectively solved.

The invention discloses a surface object collection device and method with a comb-shaped shovel rotary structure and an integrated conveying-separating structure. The surface object collection device comprises a frame, two electric drive tracks, a battery, an automatic baler, a hollow conveyor belt, a frequency-adjustable vibrating screen, a rotary comb-shaped shovel, rake teeth, a hard brush and an image recognition and sensor module. The image recognition and sensor module comprises a camera device, an infrared sensor, a deep learning algorithm module and a pressure sensor. By identifying the characteristic size, type, density and burial degree of surface objects and measuring the force applied to the rotary comb-shaped shovel, the sand entry angle of the rotary comb-shaped shovel, the operating speed of the hollow conveyor belt and the vibration frequency of the frequency-adjustable vibrating screen are adjusted to reduce the sand entry resistance of the rake teeth, and adjustments are made for bottom materials with different particle sizes, types and densities and objects of different scales to improve the sand screening efficiency of the mixture.
