Problems solved by technology

However, due to the limitation of many factors such as the overall weight requirements of the machine tool, the overall size of the gearbox on the stubble removal side and the gearbox on the rotary tillage side of the current combined land preparation machine is relatively small, and the amount of lubricating oil for the gears filled inside is limited. In actual operation, The temperature of the lubricating oil in the gearbox on the stubble removal side and the gearbox on the rotary tillage side is too high, the viscosity drops, and even gasification occurs, the pressure in the box increases, the lubricating oil film cannot be formed, the impurities increase, the oil quality decreases, and the lubricating ability is greatly reduced , resulting in increased wear of gears, bearings and other parts, serious oil leakage from the box, shortened service life, increased failure rate, increased maintenance costs, and reduced operating efficiency

Abstract

The invention discloses a circulating cooling system for gearbox lubricating oil of a combined land preparation machine, belonging to agricultural machinery. A rack assembly is provided with a stubble ploughing main gearbox, a rotary tillage main gearbox, a stubble ploughing side gearbox and a rotary tillage side gearbox, wherein the stubble ploughing main gearbox and the rotary tillage main gearbox are respectively and fixedly provided with a first oil pump and a second oil pump, a first connecting oil pipe provided with a first filter is used for communicating the first oil pump with the stubble ploughing main gearbox, a lubricating oil heat-dissipation output pipe and a return pipe of the stubble ploughing gearboxes are used for communicating the first oil pump, the stubble ploughing side gearbox and the stubble main gearbox to form a lubricating oil circulating cooling system of the stubble ploughing gearboxes; and a second connecting oil pipe provided with a second filter is usedfor communicating the second oil pump with the rotary tillage main gearbox, and a lubricating oil heat-dissipation output pipe and a return pipe of the rotary tillage gearboxes are used for communicating the second oil pump, the rotary tillage side gearbox and the rotary tillage main gearbox to form a lubricating oil circulating cooling system of the rotary tillage gearboxes. The circulating cooling system disclosed by the invention is reasonable in design, has a good effect of cooling the lubricating oil, and has a long service life.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a gearbox lubricating oil cooling system on a soil preparation machine tool that completes the combined operations of stubble removal and rotary tillage. Background technique [0002] Stubble removal and rotary tillage combined soil preparation machine is currently one of the main models in dry farming in northern my country, which has played a positive role in improving the level of agricultural mechanization. However, due to the limitation of many factors such as the overall weight requirements of the machine tool, the overall size of the gearbox on the stubble removal side and the gearbox on the rotary tillage side of the current combined land preparation machine is relatively small, and the amount of lubricating oil for the gears filled inside is limited. In actual operation, The temperature of the lubricating oil in the gearbox on the stubble removal side and the gearbox on the...
