Wheel type telescoping passive variable amplitude mower

Abstract

The invention discloses a wheel type telescoping passive variable amplitude mower. The mower includes a chassis walking device, a bottom mowing device and two sets of obstacle-avoiding and mowing devices; the two sets of the obstacle-avoiding and mowing devices are symmetrically arranged on the two sides of the chassis walking device; the chassis walking device includes a front axle, a rear axle,a vehicle rack, walking wheels and walking power mechanisms; the bottom mowing device includes a rack and a main mowing mechanism; the obstacle-avoiding and mowing devices include swing arms in hingedjoint with the middle part of the vehicle rack, auxiliary mowing mechanisms arranged on the tail ends of the swing arms, adaptive telescoping mechanisms and driving mechanisms, and the adaptive telescoping mechanisms include sliding holes arranged in the tail ends of the swing arms, telescoping members slidingly cooperated with the sliding holes and adaptive springs respectively arranged on the two sides of the telescoping members; one ends of the adaptive springs act on the swing arms, and the other ends of the adaptive springs act on the telescoping members; and the auxiliary mowing mechanisms are rotatably connected to the telescoping members. The mower is high in adaptability and large in weeding range, and can automatically avoid fruit trees on the two sides to mow the weeds around tree trunks and between the two front and back fruit trees.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a wheeled retractable passive luffing mower. Background technique [0002] Lawn mower is the most commonly used a kind of mowing equipment in the prior art, and lawn mower is also called weeder, lawnmower, lawn trimmer etc. A lawn mower is a mechanical tool for mowing lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, a blade, a handrail, and a control part. The cutterhead is installed on the walking wheel, the cutterhead is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, which saves the working time of the weeding workers and reduces a lot of human resources. [0003] With the continuous development of science and technology, modern lawn mowers have become more and more mature. For example, the patent...

AI Technical Summary

Problems solved by technology

But above-mentioned lawnmower has following deficiency: because the double-cutter disc throwing knife device is arranged under the chassis, if above-mentioned lawnmower is used in orchard, the scope of above-mentioned lawnmower mowing operation can only be limited to lawnmower In the direction of travel, the fruit trees on both sides cannot be automatically avoided, so that the mower cannot fully reach around the trunk, and cannot clear the weeds between the two fruit trees before and after. The range of weed removal is limited, and the adaptability and flexibility are not high.
