Problems solved by technology

The suspension device of the existing paddy field operation machine can only increase the tension through the deformation of the buffer spring to limit the inclination angle of the rear axle. It lacks the protection of the buffer spring. When the inclination angle of the rear axle is too large, the spring may collapse. Problems such as damage, mutual interference and collision between the wheels and the frame, and cracking of the frame caused by excessive freedom of the frame

Abstract

The invention provides a rear axle suspension device and a paddy field operation machine. The rear axle suspension device comprises a machine frame, a rear axle located under the machine frame, an elastic piece connected with the rear axle and the machine frame, and a limiting mechanism arranged between the rear axle and the machine frame. When the inclination angle of the rear axle relative to the machine frame is not greater than an inclination angle threshold value, a moving space is formed between at least one of a rack and the rear axle and the limiting mechanism; and when the inclination angle of the rear axle relative to the rack reaches an inclination angle threshold value, the limiting mechanism locks the rack and the rear axle. The paddy field operation machine comprises the rear axle suspension device. When the inclination angle of the rear axle relative to the rack reaches an inclination angle threshold value, the limiting mechanism locks the rack and the rear axle and limits the rear axle to continuously rotate relative to the rack, so that the safety distance between wheels and the rack is guaranteed, and mutual interference and collision between the wheels and the rack are prevented.

Description

technical field [0001] The invention relates to the field of paddy field operating machines, in particular to a rear axle suspension device and a paddy field operating machine. Background technique [0002] A common paddy field operation machine generally includes a frame and a rear axle arranged under the rear part of the frame, and the rear axle is used for connecting wheels. The rear axle is connected with the frame through springs to form a suspension device, and the rear axle can rotate relative to the frame. The suspension device of the existing paddy field operation machine can only increase the tension through the deformation of the buffer spring to limit the inclination angle of the rear axle. It lacks the protection of the buffer spring. When the inclination angle of the rear axle is too large, the spring may collapse. Damage, mutual interference and impact between the wheels and the frame, and cracking of the frame caused by excessive freedom of the frame. Cont...
