Improved structure of hydraulic pipeline capable of supplying oil in box

The utility model relates to the technical field of agricultural machinery, in particular to an in-box oil supply type hydraulic pipeline improved structure which comprises a gearbox body, a hydraulic oil pump and a pipeline system, the hydraulic oil pump and the pipeline system are arranged in the gearbox body, and the hydraulic oil pump is communicated with the pipeline system. The hydraulic oil pump and the pipeline system are installed in the gearbox body, so that the hydraulic oil pump and the pipeline system are prevented from making contact with the outside, corrosion of the outside to the hydraulic oil pump and the pipeline system is avoided, the service life of the hydraulic oil pump and the service life of the pipeline system are prolonged, and the maintenance difficulty is reduced. 本实用新型涉及农业机械技术领域，尤其涉及一种箱内供油式的液压管路改进结构，包括变速箱体、液压油泵和管路系统，液压油泵和管路系统设置在变速箱体内部，液压油泵和管路系统连通。将液压油泵和管路系统安装在变速箱体的内部，从而避免了液压油泵、管路系统和外界接触，从而避免了外界对液压油泵和管路系统的腐蚀，从而延长了液压油泵和管路系统的使用寿命，减少了维护难度。
