A high-speed rice transplanter chassis driven by hydrostatic pressure

Abstract

The invention relates to a hydrostatic drive high-speed transplanter chassis. An engine provides a power source for a two-way plunger variable pump and an auxiliary gear pump. The two-way plunger variable pump is connected with a two-stage variable traveling transplant motor through a closed circuit and provides power for a parking brake control valve. An output shaft of the two-stage variable traveling transplant motor is connected with a mechanical transfer case, and the mechanical transfer case transmits power to an inter-axle differential and transplant mechanism speed change and power separation boxes. The transplant mechanism speed change and power separation boxes are connected with a transplant drive mechanism, the power separation box determines whether a transplant mechanism works or not, and the transplant mechanism speed change box adjusts the transplant plant spacing according to different transmission ratios. The output end of the auxiliary gear pump is connected with a flow distribution valve. The flow distribution valve distributes oil liquid to a high-speed electromagnetic reversing valve and a profiling mechanism control valve, the high-speed electromagnetic reversing valve and a steering gear control a steering oil cylinder, the profiling mechanism control valve controls a profiling mechanism oil cylinder, and a transplant mechanism lifting oil cylinder is controlled by a transplant mechanism lifting control valve.

Description

technical field [0001] The invention relates to a chassis of a high-speed rice transplanter, in particular to a chassis of a high-speed rice transplanter driven by hydrostatic pressure, and belongs to the technical field of rice transplanters. Background technique [0002] With the advancement of Made in China 2025 technological innovation, agricultural machinery is required to develop towards mechanization, automation, and intelligence. Especially in recent years, my country has become the world's largest agricultural equipment production and use country. The development of agricultural equipment is to continuously increase land output. The most basic material guarantee and core support for realizing agricultural modernization. [0003] Paddy field agricultural machinery has been working in paddy fields with poor driving conditions for a long time, and it is necessary to ensure its normal driving and operation quality, which makes the drive design of the chassis extremely st...
