Problems solved by technology

However, the inventors have found that the excessive rigidity of the touch lever is very easy to be damaged due to entanglement of weeds or collision during detection, and at the same time, it is easy to cause collision damage to the plant body, which is not conducive to the harvest of vegetables and other crops
Although a hard pole with too much elasticity can reduce the chance of entanglement with weeds or collision damage, the hard surface will inevitably cause collision damage to the plant body, and the greater elasticity will strongly interfere with the detection signal, which is not conducive to accurate detection.

Embodiment 2

[0034] This embodiment discloses a harvester, the front end of the harvesting platform is fixedly connected to the flexible touch-type plant body detection sensor described in Embodiment 1 through a threaded mounting hole, and the output terminal on the housing is connected to the harvester through a connecting wire. Machine controller connection.

[0035] Two flexible touch-type plant body detection sensors described in Embodiment 1 are installed on the harvesting platform of the harvester, and the movable ends of the two flexible touch-type plant body detection sensors are arranged close to each other, which can detect the movement of the harvester. The offset can also detect the volume and outer contour of the plant body.

[0036] In another embodiment, two flexible touch-type plant body detection sensors described in Embodiment 1 are installed on the harvesting platform of the harvester. The row offset of the harvester.

Embodiment 3

[0038] This embodiment discloses a working method of the flexible touch-type plant body detection sensor described in Embodiment 1. When the touch bar touches the crop plant body, it will be bent and deformed, and the touch bar will be squeezed after being bent and deformed. The pressure strain gauges of the pressure strain gauge group, so that the pressure strain gauges generate voltage signals, each pressure strain gauge on the pressure strain gauge group can output an independent signal to the signal processor, when the crop plant is closer to the sensor, the flexible touch The greater the bending deformation of the touch strip, the flexible touch strip will sequentially squeeze the pressure strain gauges on the strain gauge group with the increase of the bending deformation, and the position of the maximum extrusion force will also change on the pressure strain gauges. The signal processor analyzes each The pressure change of a pressure strain gauge can analyze the bending ...

Abstract

The invention relates to a flexible touch type plant sensor, a harvester and a method; a shell is included, and the shell is fixedly connected with one end of a touch strip made of a flexible material; the shell is provided with an arc-shaped surface, the arc-shaped surface is provided with a pressure strain gauge set, the touch strip can touch a plant to be bent, the bent touch strip can make contact with the pressure strain gauge set on the arc-shaped surface, and the sensor cannot cause collision damage to the plant during work.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a flexible touch-type plant body sensor, a harvester and a method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As an important part of agricultural production, the harvester is difficult to operate and the driving intensity is high. The driver needs to constantly adjust the direction of the harvester to align it with the crop growth line to ensure smooth harvesting. In view of the cumbersome operation of the harvester, researchers have gradually developed the auxiliary driving technology of guided harvesting. At present, the detection methods that this technology mainly relies on are mostly rigid or elastic touch detection methods, which mainly collide with the crop plant body through a rigid metal or nylon plastic touch rod, causing the touch rod ...
