Bulldozer

The invention relates to the field of engineering machinery and discloses a bulldozer. The bulldozer comprises a frame (3), a cabin (1), a portal frame (2) and a cab (4), wherein the cabin (1), the portal frame (2) and the cab (4) are arranged on the frame (3) in the front-back direction. The portal frame (2) and the cab (4) are spaced and not directly connected. According to the bulldozer disclosed by the technical scheme, the portal frame and the cab are spaced and not connected, vibration and noise generated by the cabin can be prevented from being more directly transmitted into the cab through the portal frame, the vibration and noise of the cab can be reduced, and the operation experience of operators is improved. 本发明涉及工程机械领域，公开了一种推土机，其中，所述推土机包括车架(3)、以及沿前后方向排列在所述车架(3)上的机舱(1)、龙门架(2)和驾驶室(4)，所述龙门架(2)和所述驾驶室(4)彼此间隔且不直接连接。通过上述技术方案，龙门架与驾驶室彼此间隔而不连接，可以避免机舱产生的振动和噪音通过龙门架更为直接地传递到驾驶室中，可以减少驾驶室的振动和噪音，提升操作人员的操作体验。
