Abstract

The invention discloses a land leveler, belongs to the technical field of engineering machinery, and solves the problems that in the prior art, due to the arrangement of a traditional land leveler, various elements are inconvenient to daily repair, check and maintain, and the elements are easy to collide by accidents. The land leveler is provided with a main body structure comprising a front frameand a rear frame, wherein the front frame and the rear frame are connected; a gearbox is arranged on the rear frame; a urea tank is arranged between the rear end of the rear frame and the gearbox; afuel tank is arranged in a framework of the front frame; a first protection plate is arranged on the bottom parts of the gearbox and the urea tank; and a second protection plate is arranged on the bottom part of the fuel tank. The invention is mainly applied to the land leveler.

Description

Technical field: [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a motor grader. Background technique: [0002] With the improvement of national environmental protection requirements, it is imperative to upgrade the emission of construction machinery. For this reason, the engine must deal with exhaust gas by adding an after-treatment system to meet the emission requirements. According to the requirements of the national T4 emission regulations, it is an inevitable technical solution to increase SCR and DPF in engine aftertreatment. The urea required by SCR needs to be refilled frequently during use. Therefore, the layout of the transmission system is very important for daily urea refilling, fuel refilling and daily maintenance. Maintenance has a big impact. At present, there is no layout design for domestic motor graders, while foreign motor graders mainly have two layout methods: one is that the engine and gearbox ...
