Document Type and Number:
WIPO Patent Application WO/2021/093414
Kind Code:
A1
Abstract:
An implement working attitude detection device, an agricultural working machine, and a ground engaging working method for the agricultural working machine. The device comprises a bracket (1) and a mounting plate (2) used for being connected to a walking chassis; a rotating part (3) which can move up and down is mounted on the mounting plate (2); the bracket (1) is connected to the rotating part (3) and can adjust a tilt angle by means of rotation of the rotating part (3); ground wheels (11) used for supporting the bracket (1) to walk are provided on the two sides of the bracket (1) correspondingly; the detection device further comprises a height measurement assembly used for measuring the height of the rotating part (3) and a tilt angle measurement assembly used for measuring the tilt angle of the bracket (1). The agricultural working machine comprises the walking chassis, a working implement (100) capable of adjusting the height and the tilt angle, and the implement working attitude detection device. The method comprises the steps: obtaining a height difference and an angle difference; and adjusting the height and the angle of the working implement (100) according to the comparison results of the height difference and the angle difference with preset thresholds. The implement working attitude detection device has the advantages that the structure is simple and compact, the costs are low, manufacturing and assembling are easy, working is stable and reliable, detection is accurate, and the working effect can be improved.
