Crawler-type rear obstacle avoiding mower

Abstract

The invention discloses a crawler-type rear obstacle avoiding mower which comprises a chassis walking device, a bottom mowing device and two groups of obstacle avoiding mowing devices, wherein the twogroups of the obstacle avoiding mowing devices are symmetrically arranged at the rear end of the chassis walking device; the chassis walking device comprises a frame, a crawler-type walking mechanismand a walking power mechanism; the bottom mowing device comprises a rack and a main mowing mechanism; the obstacle avoiding mowing devices comprise swinging arms, secondary mowing mechanisms, self-adaptive telescopic mechanisms and driving mechanisms; the self-adaptive telescopic mechanisms comprise sliding holes which are formed in the tail ends of the swinging arms, telescopic parts which are in sliding matching with the sliding holes, and self-adaptive springs which are respectively arranged on both sides of the telescopic parts; the sliding holes extend along axis directions of the swinging arms; one end of each self-adaptive spring acts on one swinging arm; the other ends of the self-adaptive springs act on the telescopic parts; and the secondary mowing mechanisms are rotationally connected with the telescopic parts. The mower is capable of automatically avoiding fruit trees on both sides and mowing off grass around trunks and grass between front trees and rear trees, and is large in mowing range, good in adaptability and good in flexibility.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a crawler type rear obstacle avoidance lawn 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 ...

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.
