Abstract

The invention relates to the technical field of agricultural machinery for weeding, in particular to a symmetrical and rotary seedling weeding unit, which comprises a symmetrical weeding cutter device and a rotation information detection device. The weeding unit is characterized in that two disc-shaped weeding cutters with notches are symmetrically arranged, and meanwhile, the gear transmission is adopted, so as to effectively realize the symmetrical and same-speed rotation of the weeding cutters in the working and engineering processes, improve the coverage rate of the weeding cutters in the seedlings, and further improve the weeding rate in the seedlings; and two sensors for detecting rotation speed information and position information are adopted, and the rotation speed information and the position information are fed back to the controller of the intelligent seedling weeding machine, so as to realize the closed loop control, and more accurately control the movement of the weeding cutters. The symmetrical and rotary seedling weeding unit has the advantages that the structure is simple, the components are compact, the processing and the installation are convenient, the practicality is high, the sealing performance is good, and the operation in rainy days is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery for weeding, in particular to a symmetrical rotating inter-seedling weeding unit, which is suitable for an intelligent inter-seedling weeding machine. Background technique [0002] The commonly used weeding methods in my country are manual weeding and chemical weeding. Among them, manual weeding takes up a lot of labor and the efficiency of weeding is low. Although chemical weeding saves manual labor, long-term spraying of chemical herbicides will lead to replacement of weed populations in farmland, frequent herbicide damage, and weed resistance. Enhancement, residue accumulation in food and environmental pollution, coupled with people's extensive demand for green food, mechanical weeding with high efficiency, no pollution, and no associated hazards has become the development trend of weeding in the future. At present, automated mechanical weeding, as one of the key technologies of...
