Four-wheel self-leveling vibration reduction orchard operation chassis and leveling vibration reduction method thereof

Abstract

The invention discloses a four-wheel self-leveling vibration reduction orchard operation chassis and a leveling vibration reduction method thereof. The four-wheel self-leveling vibration reduction orchard operation chassis comprises a chassis body; the chassis body is provided with a hydraulic assembly, a leveling vibration reduction assembly, a signal sensing assembly and a control unit; the hydraulic assembly is connected with the leveling vibration reduction assembly through a hydraulic pipeline; the control unit is electrically connected with the hydraulic assembly, the leveling vibration reduction assembly and the signal sensing assembly; the control unit is used for obtaining signals collected by the signal sensing assembly. According to the vertical displacement and speed of the wheel center of each wheel, the vertical displacement and speed of the four corners of the chassis body, the vertical acceleration of the mass center of the chassis body, the roll angle of the mass center of the chassis body and the roll angle acceleration of the mass center of the chassis body, the pitch angle of the mass center of the chassis body and the pitch angle acceleration of the mass center of the chassis body, an adjustment strategy of the leveling vibration reduction assembly is determined; and the elongation amount of the leveling vibration reduction assembly is controlled according to the adjustment strategy. According to the invention, the orchard operation chassis can be leveled.

Description

technical field [0001] The invention relates to the technical field of orchard picking operations, in particular to a four-wheel self-leveling orchard operating chassis and a method for leveling and vibration reduction. Background technique [0002] The orchard planting industry is one of the important pillars of my country's agricultural planting industry, and the mechanization of orchard operations is of great significance for improving the efficiency of operations. Although researchers at home and abroad have developed a variety of orchard operating machines, the existing orchard operating machines have unsatisfactory chassis leveling effects during driving, especially when driving on rough orchard roads, increasing the number of personnel on the operating machines. It is difficult to work, and while reducing the operation efficiency, there is also a large safety hazard, which makes the operation chassis at risk of rollover and pitching; in addition, when studying the lev...

AI Technical Summary

Problems solved by technology

Although researchers at home and abroad have developed a variety of orchard operating machines, the existing orchard operating machines have unsatisfactory chassis leveling effects during driving, especially on roads with large orchard unevenness, which increases the number of people on the operating machines. While reducing the working efficiency, there are also great potential safety hazards, which make the working chassis rollover and pitching dangerous; in addition, when studying the leveling effect of the orchard working chassis, less comprehensive consideration is given to the unevenness of the road surface Vibration of the operating chassis caused by high frequency. Excessive chassis vibration not only affects the comfort of the operators and easily causes fatigue of the personnel, but also increases the vibration damage of the operating machinery connected to the operating chassis, reducing the operating chassis and operating conditions.

Especially when picking fruit, the tilting and vibration of the auxiliary picking machine will also cause damage to the fruit
