Problems solved by technology

The traditional suspension mechanism can adjust the length of the lifting rod to adapt to a certain slope and terrain changes, but it must be adjusted before the operation. The operation process is in a locked state, and the adjustment effect is limited, which cannot realize the real-time ground profiling operation function.

Abstract

The invention discloses a ground contour following suspension mechanism for a tractor used in hilly and mountainous areas. The ground contour following suspension mechanism comprises a left lifting hydraulic cylinder, a right lifting hydraulic cylinder, an upper pull rod, a left lower pull rod, a right lower pull rod, a limiting hydraulic cylinder and a self-regulating limiting rod. The suspension mechanism has a transverse posture adjustable function, the maximum transverse adjustable gradient of the suspension mechanism can reach 15 degrees, and the tractor can draw a farm instrument to implement ploughing operation in the hilly and mountainous areas. The suspension mechanism can adapt to large longitudinal gradient, the maximum adaptable longitudinal gradient can reach 23 degrees, and requirements of climbing and operation of the hilly and mountainous areas can be met. The suspension mechanism can be used as an executing mechanism of the ground contour following suspension mechanism, with the aid of a terrain following hydraulic control system, ground contour following can be controlled automatically, agricultural requirements of cultivated depth uniformity of operation and gradient adaptation of the hilly and mountainous areas are met further, the operation efficiency can be greatly improved, and the operation quality is improved.

Description

technical field [0001] The invention belongs to the technical field of tractor traction suspension, and in particular relates to a tractor ground profiling suspension mechanism in hilly and mountainous areas. Background technique [0002] The tractor traction suspension mechanism is the main device for the tractor to pull the farm implements for agricultural operations. When working in a flat or undulating farmland, the existing traditional suspension mechanism can make the farm implement work normally. In areas with relatively large terrain fluctuations such as hilly and mountainous areas, the use of traditional suspension mechanisms to mount agricultural tools will cause large changes in the position and attitude between the agricultural tools and the ground. The adjustment is in a locked state and cannot be adjusted with the terrain undulations, thus resulting in poor operation quality and low operation efficiency. With the continuous improvement of the degree of agricu...
