Abstract

The invention discloses a limiting device for limiting the overturning angle of matching agricultural machinery, which comprises a connecting U-shaped plate, a limiting bracket, a limiting rod, a lower suspension connecting rod, a spring box, a rake knife, a counterweight groove, and a limiting rake frame, upper suspension link, connecting frame, connecting hinge, spring, rear spring hanging shaft, front spring hanging shaft. The connecting U-shaped plate and the rake frame are connected through a space four-link, which can generate relative movement. The rake knife and the limit rake frame are rigidly connected by bolts, and the reaction given by the spring is transmitted to the ground. The spring box is just connected to both sides of the limit rake frame, through vibration absorption including the kinetic energy generated by the relative movement between the U-shaped plate and the limit rake frame. The limit rod and the limit rake frame are connected by bearings, and the two sides are respectively inserted into the limit holes of the limit bracket to limit the range of relative swing angles. It has strong practicability and high environmental adaptability, and can effectively reduce the overturning angle of supporting agricultural machinery. .

Description

technical field [0001] The invention relates to the field of machinery for agricultural production, and is a highly adaptable and effective limiting rake mechanism for limiting the overturning angle of agricultural machinery. Background technique [0002] Agricultural mechanization is a symbol to measure the level of agricultural modernization. my country is a big agricultural country, and the development of modern agriculture cannot be separated from the continuous improvement and innovation of agricultural machinery. Tractor is the main agricultural machinery used in field agriculture. It can not only be used as a traction tool, but also can hang various types of agricultural machinery for operation. As an important power output mechanism of wheeled tractors, the power output shaft can provide power for various types of supporting agricultural machinery with double cross shaft universal joints. had a direct impact. When agricultural machinery encounters obstacles with h...
