Problems solved by technology

[0003] Most of the current self-leveling mechanisms on the chassis of small agricultural vehicles use hydraulic systems. When the chassis of small agricultural vehicles is tilted, the hydraulic push rod pushes the chassis to rotate around the fulcrum to keep the chassis level, but it is bulky and heavy

Abstract

The invention discloses an automatic leveling chassis, an agricultural vehicle and a leveling method. The chassis includes a frame, a first wheel, a second wheel and a traveling drive mechanism. The first wheel is arranged at the front of the frame, and the second There are two wheels, and the two second wheels are symmetrically arranged at the rear of the frame, and the travel drive mechanism is arranged on the frame; each second wheel includes a wheel disc, a wheel shaft, a stepping motor, a gear assembly, and a plurality of sliding mechanisms , a mounting plate and a plurality of arc-shaped tires, the stepping motor drives the wheel to rotate through the gear assembly, and there are multiple strip grooves on the wheel, and each strip groove forms a certain angle with the corresponding sliding mechanism, and corresponds The first end of the sliding mechanism is slidingly connected, and the second end of each sliding mechanism is fixedly connected with the corresponding arc tire; the axles of the two second wheels are connected. The invention can achieve a balanced state by adjusting the diameter of the wheel, has small volume and greatly reduced weight, and can better adapt to slope terrain such as hills and mountains.

Description

technical field [0001] The invention relates to a chassis, in particular to an automatic leveling chassis, an agricultural vehicle and a leveling method, belonging to the technical field of agricultural machinery. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. [0003] Most of the automatic leveling mechanisms on the chassis of small agricultural vehicles currently use hydraulic systems. When the chassis of small agricultural vehicles ...
