Wheeled agricultural robot with adaptive wheelbase adjustment function and its adjustment method

Abstract

The invention discloses a wheeled agricultural robot with adaptive wheelbase adjustment function and its adjustment method. The wheeled agricultural robot includes a control system and a car body with four driving wheel legs. There is a wheelbase adjustment actuator. The wheeled agricultural robot of the present invention can make adaptive adjustments to the wheel base according to changes in the row spacing of crops and terrain, greatly reducing the occurrence of seedling pressing, widening the applicable terrain range for agricultural robots to perform operations, and improving work efficiency. , to reduce operating costs, and the present invention has multiple adjustment modes such as synchronous adjustment of the wheel base, independent adjustment of two wheels and independent adjustment of four wheels, etc., if encountering obstacles, narrow roads and other complex terrains, it can also ensure that the chassis can run smoothly Passed, the structure planning is reasonable, easy to operate and maintain, and suitable for popularization and use.

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
