Problems solved by technology

[0005] In view of the fact that the existing technology of scallion combine harvester is not mature enough, its reliability and stability are poor, and it is easy to fail in the whole process of loosening the soil at a limited depth, excavating and conveying, removing soil, clamping and smoothing, and terminal collection during on-site operations. Problem, the object of the present invention is to provide a hydraulic system of a scallion combine harvester and a scallion combine harvester, which can realize automatic and continuous harvesting of scallions from the links of limited depth loosening, excavation and transportation, soil removal, clamping and smoothing, and terminal collection. Improve operation efficiency and automation level

Abstract

The invention discloses a hydraulic control system for a scallion combine harvester, which relates to the field of agricultural machinery and includes a hydraulic oil tank, a travel control system, an operation control system and an auxiliary manipulation control system, wherein the travel control system is a closed system, and the travel control system, Both the job control system and the auxiliary steering control system are connected to the hydraulic oil tank, and the job control system and the auxiliary steering control system are open systems; the job control system includes an electromagnetic reversing valve group and multiple hydraulic motor units. In parallel, multiple hydraulic motor units are connected to electromagnetic reversing valve groups. The invention can realize automatic and continuous harvesting of scallions from links such as limited depth loosening, excavation and transportation, soil removal, clamping and smoothing, terminal collection, etc., and improves operation efficiency and automation level.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a hydraulic system of a scallion combine harvester and a scallion combine harvester. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Green onions are one of the main characteristic economic crops in my country. They have a long history of cultivation in China. Because of their strong adaptability to the environment, they are planted all over the country. At present, the harvesting of scallions is still mainly done manually, with high labor intensity, low efficiency, relatively backward harvesting equipment, and low level of mechanized harvesting, which has become a bottleneck restricting the mechanized production of scallions. Foreign research on green onion combine harvesters started earlier, with a high level of intelligence and automation. Most...
