最后，主变速箱3上还设有用于连接耕作工具的工作输出轴26，发动机2的第二输出轴上还设有皮带轮，皮带轮通过齿轮泵连接有用于调节耕作工具高度的液压提升机构。液压提升机构包括油管、液压阀、液压操纵杆23和升降油缸25，通过调节液压操纵杆23来控制液压阀，以此来调节油管与升降油缸25之间的通断，实现升降液压缸25中活塞的伸缩。Finally, the main gearbox 3 is also provided with a working output shaft 26 for connecting the tillage tool, and the second output shaft of the engine 2 is also provided with a pulley, and the pulley is connected with a hydraulic lifting mechanism for adjusting the height of the tillage tool through a gear pump. The hydraulic lifting mechanism includes oil pipes, hydraulic valves, hydraulic joysticks 23 and lifting cylinders 25. By adjusting the hydraulic joysticks 23 to control the hydraulic valves, the on-off between the oil pipes and the lifting cylinders 25 is adjusted to realize the lifting of the hydraulic cylinders 25. The expansion and contraction of the piston.
优选的，本优选实施例中的机架1上还设有座椅24，以减少用户在作业过程中的疲劳程度。Preferably, the frame 1 in this preferred embodiment is also provided with a seat 24 to reduce the user's fatigue during the operation.
以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，熟悉该本领域的技术人员应该明白本实用新型包括但不限于附图和上面具体实施方式中描述的内容。任何不偏离本实用新型的功能和结构原理的修改都将包括在权利要求书的范围中。The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto, and those skilled in the art should understand that the present utility model includes but is not limited to the accompanying drawings and the above specific embodiments described in the content. Any modifications that do not deviate from the functional and structural principles of the present utility model shall be included in the scope of the claims.
