Description

Active suspension adjustment detection assembly and suspension type mower Technical Field The invention relates to the technical field of suspension adjustment detection, in particular to an active suspension adjustment detection assembly and a suspension mower. Background The suspended mower is widely applied to the scenes of grasslands, hills and public greens of agricultural/pasture areas by virtue of flexible operation characteristics, is used for the operations of harvesting pasture, trimming lawns and the like, and the adjustment rationality of a suspended structure directly determines the cutting quality and the service life of equipment. At present, the existing suspension type mower is mainly in a manual operation mode, an operator is relied on to adjust cutting height, a clearance between a movable blade and a fixed blade and a suspension angle according to experience, active self-adaptive regulation and control based on an actual working environment cannot be achieved, and a plurality of technical defects exist. In the aspect of ground height adaptation, the working area often has the conditions of unevenness, gradient change and the like, and the existing suspension mower lacks an effective ground height real-time detection mechanism and cannot dynamically sense the ground fluctuation change. The operator is difficult to accurately adjust the suspension height in real time, so that the cutter disc is easy to insert into the soil and collide with the ground bulge, or the problems of uneven stubble cutting height, missing cutting and the like occur, the cutting effect is affected, the abrasion of parts such as the cutter disc and a blade protector is aggravated, and the operation efficiency is reduced. In the aspects of hard object detection and cutting parameter regulation, hard objects such as stones, stumps and the like often exist in an operation area, and the existing equipment lacks a specific hard object detection component and cannot timely identify the hard objects and automatically adjust cutting gaps and heights in the cutting process. When the cutter disc contacts hard objects, blade abrasion and deformation are easy to occur, even the hanging structure is damaged, equipment is damaged, maintenance cost is increased, potential safety hazards exist, meanwhile, the area near the hard objects is easy to form missed cutting, and operation integrity is affected. Although the existing part of intelligent mowers try to integrate sensors to realize height adjustment or obstacle avoidance, the intelligent mowers are mostly aimed at small-sized flat ground scenes, are not suitable for complex working environments of suspension mowers, cannot realize ground height detection, hard object identification, cutting clearance and height linkage active adjustment and control, and are poor in suitability and practicality. Therefore, an active hanging adjustment detection assembly capable of detecting the ground height and the hard objects in the cutting path in real time and automatically adjusting and controlling the cutting gap and the hanging height and a hanging mower are developed, the defects of the prior art are overcome, and the technical problem to be solved in the prior art is solved. Disclosure of Invention The invention aims to solve the technical problems that a suspension regulating mechanism of a suspension type mower in the prior art has a limited adjustable range, weak capability of identifying obstacles, weak coping capability and poor universality.
