Automatic adjusting device for chassis height of agricultural machinery

Abstract

The invention provides an automatic adjusting device for the chassis height of agricultural machinery. The automatic adjusting device comprises a chassis, a hydraulic pump, a transverse horizontal sensing mechanism, a longitudinal horizontal sensing mechanism, a reversing valve, swinging sensors, a first hydraulic cylinder and a second hydraulic cylinder, the hydraulic pump, the transverse horizontal sensing mechanism, the longitudinal horizontal sensing mechanism, the reversing valve, the swinging sensor, the first hydraulic cylinder and the second hydraulic cylinder are arranged on the chassis, a movable steering wheel set and a corner adjusting drive arm are connected at the front end and the rear end of the chassis, two ends of the first hydraulic cylinder are connected with the chassis and the corner adjusting drive arm, two ends of the second hydraulic cylinder are connected with the chassis and the movable steering wheel set, and the transverse horizontal sensing mechanism and the longitudinal horizontal sensing mechanism are connected with the reversing valve through swinging sensors. The automatic adjusting device is designed by the aid of a modular structure, so that device overcomes the shortcoming that the chassis height cannot be automatically adjusted in the prior art, transverse horizontal and longitudinal horizontal of the chassis can be kept, so that travelingwheels sufficiently contact with the ground, stress of the traveling wheels is uniform, the agricultural machinery is good in working quality, high in efficiency and low in running cost, and the automatic adjusting device is widely matched with various agricultural machinery.

Description

technical field [0001] The invention relates to agricultural machinery equipment, in particular to an automatic chassis height adjustment device for agricultural machinery. Background technique [0002] During the design and operation of agricultural machinery, it is required to maintain a certain horizontality of the operating mechanism and thermal power in the horizontal and vertical directions to ensure the quality of agricultural machinery, power performance and operational safety. It does not have the function of automatically adjusting the height of the chassis when working on uneven mountainous terrain, and the chassis is prone to contact with the ground, resulting in unstable operation quality of agricultural machinery and frequent failures of agricultural machinery, resulting in high maintenance costs for agricultural machinery. Contents of the invention [0003] In view of the above situation, the purpose of the present invention is to provide a chassis height au...
