Problems solved by technology

In order to ensure the smoothness of the construction, the position of the blade needs to be controlled during the operation of the grader to ensure that the scraped road grooves meet the requirements. Since the position of the blade of the grader is controlled by multiple oil cylinders, each cylinder is controlled by The operator manually operates the control, which brings two problems: first, the operator has high requirements on the level of the operator, and at the same time, the labor intens

Example Embodiment

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0057] Such as Figure 1 to Figure 3 As shown, a leveling control system for a motor grader provided by the present invention includes a reference surface generating device 101 for generating a reference surface b at the work site of the motor grader. The sensor is used to detect the state parameters of the motor grader when it is working and generate a detection signal. The controller 102 is used to receive and process the detection si...

Abstract

The invention relates to a land leveler leveling control system, a control method and a land leveler. The leveling control system comprises a datum plane generation device, a sensor, a controller, a target order input device and reference points, wherein the reference points and the land leveler are arranged at interval; the spatial position of reference points is calculated by a signal detected by the sensor and the controller; the scraper knife target position is calculated by being combined with an input target position information; and the control signal of the corresponding motion amountis calculated and is sent to a driving mechanism in the land leveler. Because the reference points are arranged in the whole control process, the position of the scraper knife is controlled in space to have a relative reference object. The motion amount of each oil cylinder and each motor in the land leveler is accurately controlled to precisely control the position of the scraper knife. The landleveler provided with a leveling control system can perform the action on precisely controlling the scraper knife and improving leveling effect. With the leveling control method, a method for causingthe land leveler to effectively control leveling and improve the operation efficiency of the land leveler is provided.

Description

technical field [0001] The invention relates to a leveling control system for a grader. In addition, the invention also relates to a leveling control method for a grader and a grader equipped with a leveling control system. Background technique [0002] As a multi-purpose continuous operation earthmoving machine for land leveling and shaping operations, the motor grader plays an incomparable role in the roadbed leveling construction. In order to ensure the smoothness of the construction, the position of the blade needs to be controlled during the operation of the grader to ensure that the scraped road grooves meet the requirements. Since the position of the blade of the grader is controlled by multiple oil cylinders, each cylinder is controlled by The operator manually operates the control, which brings two problems: first, the operator has high requirements on the level of the operator, and at the same time, the labor intensity is high; second, the leveling accuracy cannot...
