Problems solved by technology

[0003] For a long time, planting, harvesting and other work have required the participation of a large number of laborers. Due to the obstruction of complex terrain, the operation process is time-consuming and laborious, and there are still some unsafe human operations.
Many of the machinery and equipment currently in use are directly transferred from agricultural and garden machinery in the plains to the production process. The chassis structure used is not fully suitable for the irregular operating environment of hills and mountains, such as crossing ravines, ridges, etc. Obstacles, there are problems such as relatively poor driving passability; at the same time, the large-slope operating conditions in hilly and mountainous areas put forward higher requirements for the chassis of the mechanical equipment currently used, but the chassis of the mechanical equipment currently used has limited climbing ability, and the large-slope Stability at work also needs to be improved

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 ​...

Abstract

The invention relates to the technical field of vehicle chassis, in particular to an agricultural all-terrain walking type deformable chassis device and an uphill and downhill method.The agricultural all-terrain walking type deformable chassis device comprises a chassis device body and an auxiliary supporting device.The chassis device body comprises a rotary table, supporting legs and a driving unit, one end of each supporting leg is hinged to the rotary table, and the other end of each supporting leg is provided with the driving unit; the auxiliary supporting device comprises a telescopic supporting device, and the telescopic supporting device is arranged at the lower end of the rotary table. The robot can adapt to complex and changeable terrains such as hills and mountains through movement cooperation between the supporting legs and the auxiliary supporting devices, is flexible and has good obstacle crossing ability, the climbing performance is improved, and the large-gradient working stability is more excellent.

Description

technical field [0001] The invention relates to the technical field of vehicle chassis, and more specifically, relates to an agricultural all-terrain walking-type deformable chassis device and a method for going up and down slopes. Background technique [0002] On the vast land of China, there are complete types and shapes of terrain, among which hilly and mountainous areas are vast, accounting for about 2 / 3 of the total area of ​​the country. In recent years, with the proposal of our country's rural revitalization strategy, people living in hilly and mountainous areas, with the encouragement and help of government policies, rely on the unique advantages of terrain to develop characteristic industries and cultivate characteristic economies, such as characteristic forest fruit economy, cultivation of economic trees, etc. . With the development of fruit and wood industry, practical problems such as low degree of mechanization and lack of advanced machinery and equipment will ...
