Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of caterpillar track travelling agricultural machinery braking quality test device, including test device ontology 2 and belt
8, the both sides of test device ontology 2 are symmetrically arranged with holder 3, are rotated on holder 3 and are provided with roll shaft 6, and between two roll shafts 6
It is sequentially connected by belt 8, the inner horizontal of belt 8 is provided with support plate 11, and symmetrical before and after the both ends outside of support plate 11
It is provided with fixed block 12, the bottom of fixed block 12 is connected by the first telescopic rod 5 and the transmission of the first MYT3-23 hydraulic drivers 4
It connects, the front and rear sides of belt 8 are symmetrically arranged with supporting block 9, and the bottom of supporting block 9 passes through the second telescopic rod 10 and second
MYT3-23 hydraulic drivers 13 are sequentially connected.
The outside of holder 3 is both provided with gradient plate 1, and the front side of holder 3 is fixedly installed rangefinder 7, gradient plate 1 and water
