Problems solved by technology

[0003] In addition, in order to improve the flatness of the working ground as much as possible during the fine leveling condition of the motor grader, it is necessary to temporarily reduce the driving speed and then automatically return to the original constant speed when driving at a constant speed. However, the above-mentioned throttle linkage control The device does not solve the problem

Abstract

The invention discloses a land leveler and an engine throttle linkage control device of the land leveler. The engine throttle linkage control device comprises an acceleration pedal, a deceleration pedal, a hand accelerator, a first semi-shaft, a second semi-shaft, a second linkage shaft and a detection device. The first end of the first semi-shaft is connected with the hand accelerator, the first end of the second semi-shaft is connected with the acceleration pedal and a preset gap is reserved between the first semi-shaft and the second semi-shaft. Repelling force exists between the first semi-shaft and the second semi-shaft in a preset state. The detection device is used for detecting actions of the hand accelerator. According to the actions of the hand accelerator, the repelling force between the first semi-shaft and the second semi-shaft is controlled. The first end of the second linkage shaft is connected with the acceleration pedal and the second end of the second linkage shaft is connected with an engine. The deceleration pedal is connected with the acceleration pedal through a swinging mechanism. According to the engine throttle linkage control device, the engine revolves at the fixed speed, the acceleration pedal does not need to be stamped all the time and at the same time, the function that after the engine is slowed down temporarily, the speed of the engine is automatically restored to the original revolution speed is achieved.

Description

technical field [0001] The invention relates to engine throttle control technology, in particular to a motor grader and an engine throttle linkage control device thereof. Background technique [0002] The motor grader needs to run at a constant speed in transition conditions or some other working conditions. At present, to make the motor grader drive at a constant speed, it is necessary to keep pressing the accelerator pedal, which is likely to cause fatigue to the operator's legs. In order to solve the above problems, such as figure 1 As shown, the Chinese patent "ZL201020559746.3" discloses a throttle linkage control device for construction machinery, including a foot throttle 1, a first connecting flexible shaft 2 and a bracket 3, the foot throttle 1 is installed on the bracket 3, and the first connecting soft shaft One end of axle 2 is connected with foot accelerator 1, and the other end is connected on the engine of machine, and one end of foot accelerator 1 is provide...
