Problems solved by technology
However, the existing agricultural crawler tractors are mainly aimed at operations in plain areas, and the posture of the body cannot be adjusted to meet the operation requirements in complex hilly and mountainous areas. A safe and reliable miniature mountain crawler tractor with adjustable posture to meet the requirements of farmland operations in hilly and mountainous areas and improve the level of agricultural mechanization in hilly and mountainous areas of our country
[0003] Due to the complex structure of the miniature mountain crawler tractor, the adjustment of the pure mechanical mechanism cannot realize the attitude adjustment of the tractor to meet the requirements of the mountain crawler tractor operation.

Abstract
The invention belongs to the field of miniature mountain tractors, and relates to a tractor rack test system, in particular to a miniature mountain track tractor rack test system. The miniature mountain track tractor rack test system comprises a tractor steering brake oil way, a tractor transverse posture adjusting oil way, a tractor longitudinal posture adjusting oil way, a tractor three-point suspension oil way, a matched farm implement oil way, a first integrated block, a second integrated block, a second one-way valve, an engine, a hydraulic pump, a filter, a hydraulic oil tank, a two-position two-way electromagnetic overflow valve, a pressure gauge and a tractor rack electrical system. According to the miniature mountain track tractor test system, the working requirements of a mountain track tractor with an adjustable posture are met, and the reliability of the system and the part of the miniature mountain track tractor is verified.
Description
technical field [0001] The invention belongs to the field of miniature mountain tractors, and relates to a tractor bench test system, in particular to a miniature mountain crawler tractor bench test system. Background technique [0002] Our country has a vast territory, including a large area of hills and mountains. These areas have complex terrain, steep slopes, and irregular road surfaces. When agricultural tractors are operating in this area, due to the sideways shift of the center of gravity, the adhesion of the tracks on both sides is different, and the risk of tipping is extremely prone to occur. In recent years, with the country's support for agricultural equipment in weak areas, my country's agricultural crawler tractors have developed rapidly. However, the existing agricultural crawler tractors are mainly aimed at operations in plain areas, and the posture of the body cannot be adjusted to meet the operation requirements in complex hilly and mountainous areas. A...
