Background

In recent years, domestic and foreign mowing machines are rapidly developed and can be classified into a pushing type, a riding type and a tractor suspension type according to operation modes. In agriculture and forestry, mowers are generally used for grass harvesting and lawn mowing. With the rise of orchard agriculture, people put forward higher requirements on orchard management in order to seek for higher economic benefits, ecological benefits and social benefits for orchards. In this context, orchard mowers are gradually emerging. The push type mower is a mowing mode of manually pushing a small mower to mow, wastes time and labor and is not suitable for orchard operation of large area; the orchard mower at home and abroad mostly adopts riding type large-scale mowing machinery, and has the defects of uneven cutting and serious cutting missing phenomenon. Due to the difference of the landform and the landform of various regions in China, in orchards with smooth lands in some regions, stubbles are simple to leave, and the common lawn mowers can work adequately. However, as one of the three fruit growing areas in China, in Shaanxi, the orchard growing area is mostly distributed in hilly and mountainous lands, the flatness is poor, the terrain is complex and uneven, a common mower cannot be used as power, the complicated working environment cannot be adapted, the operation effect is poor, and the efficiency is low. Therefore, a multidirectional terrain-imitating mowing operation device suitable for hilly and mountainous orchards is urgently needed. The device changes the angle of the mowing plane of the cutter head by compressing or stretching three springs provided with pneumatic push rods so as to reduce the cutting missing phenomenon of the mower in the working process, realize the profile modeling of uneven ground and improve the adaptability of the mower in hilly mountains.
