Wheeled agricultural robot with self-adaptive wheel track adjusting function and adjusting method thereof

Abstract

The invention discloses a wheeled agricultural robot with a self-adaptive wheel track adjusting function and an adjusting method of the wheeled agricultural robot, the wheeled agricultural robot comprises a control system and a vehicle body provided with four driving wheel legs, and the wheeled agricultural robot is characterized by further comprising a wheel track adjusting executing mechanism. The wheeled agricultural robot provided by the invention can work according to the row-line spacing of crops and the terrain change; the wheel track is adaptively adjusted; the seedling pressing phenomenon is greatly reduced; the applicable terrain range of the agricultural robot for executing the operation is widened; the working efficiency is improved, the operation cost is reduced, multiple adjustment modes such as synchronous adjustment of wheel track, independent adjustment of two wheels and independent adjustment of four wheels are achieved, the chassis can smoothly pass through complex terrains such as obstacles and narrow road sections, the structural planning is reasonable, the operation and maintenance are easy, and the chassis is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a wheeled agricultural robot with an adaptive wheelbase adjustment function and an adjustment method thereof. Background technique [0002] As the contradiction between the growing population and the shortage of water and land resources and labor in agricultural production becomes increasingly apparent, it is urgent to improve the efficiency of agricultural production. It is an inevitable trend in the development of agricultural mechanization to use agricultural robots to replace humans in whole or in part to complete complex tasks efficiently, safely and reliably. [0003] For example, the prevention and control of crop diseases, insect pests and weeds in my country has become the most labor-intensive, labor-intensive, and most frequent operation link in the agricultural production process, and spraying pesticides, herbicides and other pesticides and liquid chemic...

Problems solved by technology

[0004] However, there are many hilly and mountainous cultivated lands in our country. Planting crops planted or transplanted by machinery will cause inconsistent planting row spacing due to the precision of the machinery and uneven ground.

Manned boom sprayers, intertillage weeders, and conventional self-driving agricultural robots will all have wheel pressure. Although in most cases the driver is driving the machine along the crop row, the autonomous navigation robot will follow the crop row in real time. Adjust the course of the chassis, but these field management tools do not have the function of adaptive wheelbase adjustment, and ground obstacles such as bumps and pits will still cause chassis bumps or small agricultural robots cannot pass
