Telescopic track chassis for small-sized tractor

Abstract

The invention discloses a telescopic track chassis for a small-sized tractor. The telescopic track chassis consists of a telescopic mechanism and track walking mechanisms. The telescopic mechanism comprises a hydraulic oil cylinder, a hydraulic oil cylinder bushing, an edge frame, a guide bushing and a vehicle frame, wherein the edge frame is driven to move by the telescopic movement of the hydraulic oil cylinder, a distance of the edge frame and the vehicle frame is changed, meanwhile a baffle and a tensioning device are driven to move by the edge frame through a support, and a track is driven to move by the movement of a driving wheel and a guiding wheel which are respectively driven by the baffle and the tensioning device, so that the track walking mechanisms on two sides of the vehicle frame are enabled to transversely move to realize the adjustment of a rail distance of the track. According to the telescopic track chassis for the small-sized tractor, the rail distance of the track can be adjusted, the structure is small and exquisite, the mass is light, the center of gravity is low, the installation is convenient, and the telescopic track chassis is suitable for various working situations, such as a narrow space, smooth ground, a hill, a mountain and the like.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a chassis structure, in particular to a retractable crawler chassis of a small tractor with adjustable track gauge. Background technique [0002] The distance between the crawler running mechanism and the frame of the existing small tractor crawler chassis is fixed, and the track gauge cannot be adjusted. When the track gauge is small, it works well on flat land, and its stability is stable on uneven ground such as hills and mountains. Poor passability. When the track gauge is large, the stability and passability are better on uneven ground such as hills and mountains, but it is not suitable for small and flexible working conditions such as greenhouses with small spaces. At present, small tractors equipped with crawler chassis can only be used in specific environments, and the application range is relatively narrow, so they cannot maximize their working capabilities.
