Embodiment 1
[0047] as attached Figure 1 to Figure 9 As shown, an agricultural all-terrain walkable deformable chassis device includes a chassis device and an auxiliary support device. The chassis device adopts a symmetrical structure and includes a turntable 1, legs and a drive unit 14. One end of the leg is hinged to the turntable 1. The other end of the leg is provided with a drive unit, and the auxiliary support device includes a telescopic support device 9 , which is arranged at the lower end of the turntable 1 .
[0048] The turntable 1 adopts a rectangular steel structure frame, with four hinged seats on the top and bottom respectively, and two connecting ears on the front and rear extending outwards around it, the front connecting ears have longitudinal connecting holes, and the rear connecting ears have horizontal connecting holes .
[0049] The supporting legs include two front supporting legs and two rear supporting legs which are arranged symmetrically respectively. The join...
Embodiment 2
[0061] An uphill method for an agricultural all-terrain walking-type deformable chassis device, comprising the following steps:
[0062] S1. Before climbing a slope, first carefully observe the driving slope, evaluate the site conditions, and judge whether the slope angle is within the maximum driving slope angle allowed by the all-terrain walking deformable chassis, and must be used when the slope angle exceeds 40° from the horizontal plane. safety guards;
[0063] Carefully check and remove debris on the slope that may affect the running of the chassis, such as large stones, fallen branches, and small stones that affect the running of the triangular track assembly, and at the same time fill in the larger unevenness on the running slope as much as possible place.
[0064]S2. Control the elongation of the lifting hydraulic cylinder 16, put down the telescopic support device 9, and the telescopic hydraulic cylinder 906 pushes the second telescopic arm 902 to stretch out. When ...
Embodiment 3
[0069] A downhill method for an agricultural all-terrain walking-type deformable chassis device, comprising the following steps:
[0070] S1. In order to avoid interference, the distance between the two rear outriggers should be greater than the length of the support plate. The ground is supported by the support claw 4, and the telescopic hydraulic cylinder 906 pushes the second telescopic arm 902 to extend, and the extended distance is the maximum stroke of the telescopic hydraulic cylinder 906, the telescopic arm is lowered by the lifting hydraulic cylinder 16, and the auxiliary support plate 903 is adaptively adjusted so as to maintain a parallel or nearly parallel state with the slope and support it on the ground;
[0071] S2. After the second telescopic arm 902 is fully extended, the pressure sensor 18 detects the oil pressure values of the telescopic hydraulic cylinders 906 on both sides. If the measured pressure values meet the threshold requirements and the values ...
