Grass height detection device and mower

Abstract

The invention provides a grass height detection device and a mower. The grass height detection device is mounted on a moving part and includes a shift plate and a height measuring mechanism; the upperend of the shift plate is rotationally connected with the moving part through a rotary shaft; the lower end of the shift plate is above a ground; the axis of the rotary shaft is perpendicular to a moving direction of the moving part such that when the moving part is in motion, the shift plate is driven by grass to rotate; the height measuring mechanism helps detect real-time rotational angle of the shift plate; the greater the rotational angle of the shift plate, the taller the grass, and on the contrary, the smaller the rotational angle of the shift plate, the more dwarf the grass; grass height can be judged according to angle changes, the grass is quantified to great extent, fewer manual judgments are required, and obtained results are accurate; since manually judging grass height by eyes is not required, automation level is high, workload is reduced for workers, and working efficiency is improved; a work strategy can be adjusted according to grass height, the work strategy with lowlabor intensity can be achieved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of lawnmowers, in particular to a grass height detection device and a lawnmower. Background technique [0002] In recent years, with the improvement of people's awareness of environmental protection, the area of ​​green space in cities has increased day by day, and the workload of daily maintenance of lawns has become increasingly heavy. In order to improve the working efficiency of lawn mowers and reduce the workload of maintaining lawns, according to Highly adjust the working strategy of the mower in real time. At present, the height of the grass on the grass is basically judged by the naked eye, which is easy to make mistakes in judgment and cause large errors, and the work efficiency is also relatively low. Contents of the invention [0003] The object of the present invention is to provide a grass height detection device and a lawn mower with accurate measurement. [0004] In order to achieve the ab...
