Problems solved by technology

The patent for invention with the publication number CN104542546A "A Height-Adjustable High-Gap Sprayer Full Hydraulic Drive Chassis and Its Hydraulic System" discloses a chassis with chassis height adjustment function, but the adjustment amount is small, and it does not have a wheelbase Adjustment function; the vehicle frame disclosed in the Chinese patent "Adjustable Wheelbase Combined Tractor Telescoping Frame" with the application number CN201020217950.7 has a wheelbase adjustment function, but the direct push adjustment method of a single hydraulic cylinder is not applicable For the loaded chassis, and it is difficult to coordinate the movement during adjustment, so it is easy to produce wheelbase deviation at the left and right ends
Therefore, the chassis equipment in the prior art all has a single limitation, such as a height-adjustable chassis that can only be adjusted in height, and a wheelbase-adjustable chassis that can only adjust the wheelbase
At the same time, their adjustment mechanism is complicated, the reliability is poor, and the steering mechanism has not been redesigned, so the applicability is limited

Abstract

The invention provides a high-clearance self-propelled type chassis with adjustable axle distance and height and a steering mechanism of the high-clearance self-propelled type chassis. The invention aims at providing the high-clearance self-propelled type chassis capable of realizing the adjustable axle distance and height according to different working requirements and having the advantages of simple structure, wide adjustment range and high reliability, and the steering mechanism of the high-clearance self-propelled type chassis. The chassis and the steering mechanism of the chassis comprise a rack (1), the steering mechanism (26), an axle distance adjusting mechanism (27), a height adjustable mechanism (28), a driving wheel (41) and a steering wheel (42); the rack (1) is provided with a first reinforcing beam (2) and a second reinforcing beam (3); the steering mechanism (26) is mounted on the rack (1); one end of the axle distance adjusting mechanism (27) is hinged onto the rack (1) and the other end of the axle distance adjusting mechanism (27) is hinged onto the height adjustable mechanism (28); the height adjustable mechanism (28) is mounted on the driving wheel (41) and the steering wheel (42).

Description

technical field [0001] The invention relates to the technical field of agricultural vehicle chassis, in particular to a high-gap self-propelled chassis with adjustable wheelbase and height and a steering mechanism thereof. [0002] technical background [0003] With the development of my country's agricultural modernization and the improvement of people's living standards, people have put forward higher requirements for agricultural machinery. Since field crop cultivation, weeding, pesticide spraying and fertilization all have high requirements on the passability of agricultural machinery, there is an urgent need for a chassis with reliable steering and adjustable wheelbase and height. At present, there are many chassis with adjustable chassis height and adjustable wheelbase. The patent for invention with the publication number CN104542546A "A Height-Adjustable High-Gap Sprayer Full Hydraulic Drive Chassis and Its Hydraulic System" discloses a chassis with chassis height adj...
