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.

    本发明公开一种履带式后置避障割草机,包括底盘行走装置、底部割草装置以及两组避障割草装置;两组避障割草装置对称设置在底盘行走装置的后端;底盘行走装置包括车架、履带行走机构以及行走动力机构;底部割草装置包括机架以及主割草机构;避障割草装置包括摆臂、副割草机构、自适应伸缩机构以及驱动机构;自适应伸缩机构包括设置在摆臂末端的滑孔、与滑孔滑动配合的伸缩件以及分别设置在伸缩件两侧的自适应弹簧;滑孔沿着摆臂轴线方向延伸,自适应弹簧一端作用于摆臂,另一端作用于伸缩件,副割草机构转动连接在所述伸缩件,该割草机能够自动避让两侧的果树,割除树干周围以及前后两棵果树之间的杂草,除草范围大,适应性高,灵活性强。
