Multifunctional tractor chassis with adjustable ground clearance

Abstract

The invention particularly relates to a multifunctional tractor chassis with an adjustable ground clearance. The problems that according to an existing tractor chassis, the overall size is large, and the ground clearance is small are solved. Each wheel spacing adjusting mechanism comprises a wheel spacing adjusting sleeve and a wheel spacing adjusting rod. Wheel spacing adjusting oil cylinders are arranged between the wheel spacing adjusting sleeves and the wheel spacing adjusting rods correspondingly. Each rack lifting mechanism comprises a rack lifting upper connecting rod and a rack lifting lower connecting rod which are hinged to the corresponding wheel spacing adjusting sleeve. Rack lifting oil cylinders are arranged at the left and right ends of a rack correspondingly. Each steering mechanism comprises a steering oil cylinder and a steering vertical shaft. Steering connecting rods are arranged between the steering oil cylinders and the steering vertical shafts. Each ground clearance adjusting mechanism comprises a steering vertical shaft connecting piece, a driving wheel and a driving wheel rod, wherein a ground clearance adjusting upper connecting rod and a ground clearance adjusting lower connecting rod are arranged between the driving wheel rod and the steering vertical shaft connecting piece. A ground clearance adjusting oil cylinder is arranged between each steering vertical shaft connecting piece and the corresponding ground clearance adjusting lower connecting rod. A driving motor is further arranged at the axis of each driving wheel. The multifunctional tractor chassis meets the intertillage agriculture ground clearance requirement and inter-row operation requirement of most crops.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an off-road machine that can realize the conversion between a compact structure and a high-gap structure and meet special agronomic requirements such as intertillage of high-stem crops, inter-row operation of field management, and weeding and management operations under the canopy of orchards. Multifunctional tractor chassis with adjustable ground clearance. Background technique [0002] In the development process of agricultural mechanization, the mechanization of planting technology has always been the focus, and it is also the main symbol of modern agriculture. However, the development of various types of planting machinery is very uneven, and the degree of mechanization varies greatly. For operations such as plowing, land preparation, sowing, and wheat harvesting, the degree of mechanization has reached a relatively high level, which has played a huge role in promoting t...
