Hydraulic output connection structure used in conjunction with tractors and agricultural implements

Abstract

A hydraulic output connection structure applied to tractors and used with agricultural implements comprises a hydraulic output bottom plate, a bolt, a hydraulic output cover plate, an O-shaped seal ring I, two O-shaped seal rings II, a hydraulic output valve connecting plate, hydraulic output oil pipes, O-shaped seal rings III, and hydraulic output pipe joints. The hydraulic output valve connecting plate is mounted on the hydraulic output bottom plate. The O-shaped seal rings II are mounted at the end of the hydraulic output valve connecting plate which is fastened through the bolt; one end of one hydraulic pipe joint and one end of the other hydraulic pipe joint are tightened in two threaded holes of the hydraulic output connecting plate; the O-shaped seal rings III are set at the other ends of the hydraulic pipe joints; and the hydraulic pipe joints are connected with two hydraulic output oil pipes. The hydraulic output connection structure has the advantages that the structure need of the tractors used with various types of agricultural implements for multi-unit hydraulic output is met, the hydraulic output connection structure is convenient to mount and demount, simple in structure, low in cost and reliable in performance, and the application range of tractors, required by users, is wider.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a hydraulic output connection structure used in conjunction with tractors and agricultural implements. Background technique [0002] At present, the wheeled tractors developed in our country have been widely used in the use of hydraulic output for supporting agricultural machinery. With the rapid development of agricultural mechanization and the extensive adoption of modern operation methods such as single operation and compound operation, more and more types of agricultural machinery and implements are required for tractors, and the supporting methods tend to be diversified. In addition to the commonly used rear suspension and rear lifting devices, there are also a large number of operating tools, such as front suspension, front loading, bulldozing, rear excavation, mowing, plowing, rotary tillage and other equipment that require tractors to provide hydraulic output. However, most domesti...

AI Technical Summary

Problems solved by technology

However, most domestic tractor manufacturers use the hydraulic output valve as an optional part when the whole machine leaves the factory, and generally do not add a hydraulic output valve, or the number of hydraulic output valve groups that have been selected cannot meet the needs of users. It is difficult to find a suitable hydraulic output connection structure to externally connect the hydraulic output valve for hydraulic output operations, which limits the scope of use of the tractor
