Steering mechanism of self-propelled rice transplanter

Abstract

The invention discloses a steering mechanism of a self-propelling rice transplanter and belongs to the field of agricultural machines. An engine, a transmission assembly, a steering gear assembly and a rice transplanting operation mechanism assembly are installed on the front side and the rear side of an integral rigid rack. A gearbox assembly is rotationally installed on the lower side of the transmission assembly in a suspended mode. A gear shaft capable of being rotationally assembled with an upper bevel gear and a lower bevel gear is assembled to the portion between the inside of the lower side of the transmission assembly and the inside of the upper side of the gearbox assembly. An intermediate bevel gear shaft and the gear shaft are perpendicularly assembled to the upper portion of the gearbox assembly. An intermediate bevel gear is rotationally assembled to the intermediate bevel gear shaft. Traveling drive wheels are fixedly installed at the two ends of a power output shaft of the gearbox assembly. A circular arc internal tooth ring is fixedly installed on the gearbox assembly. A steering drive gear assembled to the steering gear assembly is engaged with the circular arc internal tooth ring. The steering mechanism is capable of saving labor during steering operation, high in turning efficiency, high in ridge combination efficiency, sufficient in driving power and reliable to use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a self-propelled rice transplanter. Background technique [0002] With the increase of rice planting area and the improvement of agricultural planting technology in Heilongjiang Province in northern my country, a self-propelled rice transplanter with moderate price, suitable for my country's planting scale and economic conditions, and labor-saving operation has been compared in rice transplanting operations. Extensive promotion and application. However, since the front and rear hinged combined frames are adopted in the structural design of the self-propelled rice transplanter, and the front frame is equipped with an engine, a storage battery, a gearbox assembly and a walking drive wheel, when the steering movement, the front machine The frame drives the engine, battery, gearbox assembly and travel drive wheel to rotate around the hinge point with the rear frame at the same time. The...

Problems solved by technology

However, since the front and rear hinged combined frames are adopted in the structural design of the self-propelled rice transplanter, and the front frame is equipped with an engine, a storage battery, a gearbox assembly and a walking drive wheel, when the steering movement, the front machine The frame drives the engine, battery, gearbox assembly and driving wheel to rotate around the hinge point with the rear frame at the same time. The operation is very laborious, the turning efficiency of the machine tool is low, and the cutting accuracy is difficult to control after turning.

In addition, the existing self-propelled rice transplanters are all driven by a single wheel, which is easy to slip during operation and lacks driving power
